Referring to
The fan 204 is mounted on the housing 201. A pipe 207 is arranged between the fan 204 and the heating cavity 206, and an interior of the pipe 207 is configured as an air extraction channel 208o enable the fan 204 to extract air from the heating cavity 206. The filter 205 is provided in the air extraction channel 208.
The heating device according to the embodiment can reduce smoke and unpleasant odor generated with heating. Specifically, the fan 204 mounted on the housing 201 is connected the heating cavity 206 through the pipe 207, and the filter 205 is provided in the air extraction channel 208 formed through the pipe 207. Therefore, while the heating member 202 in the heating cavity 206 heats the powder 302 attached to the substrate 301, the hot air in the heating cavity 206 can be continuously discharged through the filter 205. Since the filter 205 can filter the dust generated by the heating of the powder 302, the smoke and unpleasant odor generated by the dust can be reduced.
In addition, the heating device of this embodiment is typically used by individual users in some confined rooms (e.g., print rooms, studios, etc.). Such rooms generally do not have the extraction system, smoke filtration system, dust removal system, etc. for factory environments. By mounting the fan 204 on the housing 201 of the heating device and connecting the fan 204 and the heating cavity 206 through the pipe 207, it is possible to realize a miniature filtration system on the heating device itself, which does not require the user to additionally add other filtration systems in the room, and facilitates the user's use.
With reference to
The spreading portion 100 is configured to spread powder on the substrate 301. The power spreading portion 100 includes a conveyor synchronous belt 102, a feed channel 103, and a power-spreading member 104 provided in the spreading cavity 101. where at least a bottom 105 of the power spreading cavity may be configured to store the powder 302. The feed channel 103 allows the conveyor synchronous belt 102 to pass through and store the powder 302 being carried by the conveyor synchronous belt 102. The power-spreading member 104 is provided below the upper portion of the conveyor synchronous belt 102. The power-spreading member 104 is communicated with the feed channel 103. The powder 302 is carried by the conveyor synchronous belt 102 through the feed channel 103, and is dispersed toward a storage space 106 via a through hole provided in the power-spreading member 104 as the conveyor synchronous belt 102 is operated.
The substrate 301 may, for example, be a film with text, patterns and the like printed thereon, which are placed both one by one in the power spreading cavity 101, and, in addition, which may also be stored in roll form, while continuously fed and passed through the power spreading cavity 101. The powder 302 may, for example, be a hot melt powder or the like. The substrate 301 is sent to the heating cavity 206 for heating after being powdered in the power spreading cavity 101.
Specifically, the housing 201 is welded together by, for example, a left side plate 209, a right side plate 210, a front side plate 211, a rear side plate 212, a bottom plate 214, and an intermediate spacer 213 provided between the front side plate 211 and the rear side plate 212. The left side plate 209, the right side plate 210, the rear side plate 212, the bottom plate 214, and the intermediate partition 213 collectively form the powder spreading cavity 101. The left side plate 209, the right side plate 210, the front side plate 211, and the intermediate partition 213 collectively form the heating cavity 206. In addition, the front side plate 211, the intermediate partition 213, and the rear side plate 212 are lower than the left side plate 209 and the right side plate 210, respectively, thereby forming a transfer channel capable of transferring the substrate 301.
With reference to
In some embodiments, in order to improve the heating efficiency in the heating cavity 206, the heating cavity 206 may be provided with a first specular member 216, the first specular member 216 being opposite to the heating member 202. The substrate 301 is between the first specular member 216 and the heating member 202. Specifically, as a material for the first specular member 216, for example, mirrored stainless steel may be selected. The first specular reflective member 216 is, for example, directly erected on the front side plate 211 and the intermediate partition 213. In the case where the cover 203 is closed, the first specular member 216 is disposed relative to the heating member 202 disposed in the accommodating cavity 215 of the cover 203. Consequently, the heat from the heating member 202 is reflected by the first specular member 216, which can increase the heating efficiency within the heating cavity 206. The substrate 301 transferred from the power spreading cavity 101 may be directly supported on the first specular member 216, in which case, even if the powder 302 to be heated, for example, hot melt powder, etc., on the substrate 301 is spilled, it will be spilled directly on the first specular member 216, and the spilling of the powder 302 to be heated onto the bottom of the housing 201, etc., can be prevented.
In some embodiments, in order to further improve the heating efficiency within the heating cavity 206, a second specular member 217 is provided on a side of the cover 203 opposite the heating cavity 206, and the heating member 202 is mounted on the side of the second specular member 217 opposite the heating cavity 206. Specifically, the second specular member 217 is provided, for example, within the accommodation cavity 215 of the cover 203, and the second specular member 217, for example, is substantially in the shape of a box and accommodates the heating member 202 within it. Thereby, in the case where the cover 203 is closed, the first specular member 216 and the second specular member 217 are opposite to each other, which can further improve the heating efficiency in the heating cavity 206. In addition, the first specular member 216 and the second specular member 217 are also capable of insulating the heating cavity 206 to a certain extent, inhibiting the heat in the heating cavity 206 from being transferred to the housing 201 and the cover 203, which may result in the surface temperature of the housing 201 and the cover 203 being too high. In addition, in order to facilitate the discharge of smoke and the like within the heating cavity 206, a plurality of air-permeable holes 218 may be provided in the second specular member 217.
The pipe 207 may, for example, be removably mounted to the cover 203 as well as to the housing 201. A first end of the pipe 207 is connected to the cover 203 and is communicated with the heating cavity 206, and a second end is connected to the housing 201 and is opposite to the fan 204. The shape and structure of the pipe 207 is not particularly limited as long as the pipe 207 is capable of connecting the heating cavity 206 and the fan 204 so as to form an air extraction channel 208 to enable the fan 204 to extract air from the heating cavity 206. For example, the pipe 207 may be a hard pipe such as a stainless steel pipe or a flexible pipe such as a bellows. In addition, the pipe 207 may be piped from the interior of the housing 201 or may be piped from the exterior of the housing 201.
In some embodiments, in order to facilitate installation and dismantling of the pipe 207 for users, the pipe 207 is a flexible pipe. The first end of the pipe 207 is removably mounted to a first flange 219 from an outside of the housing 201. The second end of the pipe 207 is removably mounted to a second flange 220. The first flange 219 is provided on the cover 203. And the second flange 220 is provided on the housing 201. The first flange 219 may, for example, be mounted directly to an outer side of the cover 203 by means of screws or the like, and the second flange 220 may also be mounted to an outer side of the housing 201 by means of screws or the like. The shapes of the first flange 219 and the second flange 220 are not particularly limited, and it is sufficient that they have protruding portions so as to facilitate installation of the pipe 207 as a flexible pipe. The pipe 207 can be mounted to the first flange 219 and the second flange 220, for example, by means of a clamp (not shown). By using the flexible pipe as the pipe 207 and configuring the first flange 219 and the second flange 220, it is very easy for the user to install or remove the pipe 207 as needed. In addition, by using the flexible pipe to connect to the cover 203 and the housing 201 from the outside, respectively, it is easy to open or close the cover 203 without interfering with the opening or closing of the cover 203.
With reference to
The filter 205 is, for example, removably mounted between the second flange 220 and the fan 204. Specifically, for example, the fan 204 is mounted into the housing 201 via a mounting bracket 221. The mounting bracket 221 presses the filter 205 to fit the filter 205 against the housing 201. For example, the mounting bracket 221 may also be substantially box shaped. The depth of the mounting bracket 221 is less than the thickness of the filter 205. The mounting bracket 221 is mounted to the inside of the housing 201 spaced apart from the filter 205 and is mounted at the location of mounting the second flange 220 of the housing 201. Thus, the filter 205 can be reliably mounted. In addition, the mounting bracket 221 can be provided with a notch for removal, and when the filter 205 needs to be removed and replaced, the filter 205 can be removed directly along the notch.
While the above illustrates an example of a heating device forming a the air extraction channel 208 through a pipe 207, it is not limited thereto.
Specifically, a second embodiment of the disclosure provides another heating device, which includes a housing 201, a heating member 202, a cover 203, a fan 204, and a filter 205.
The housing 201 is provided with a heating cavity 206 and an air extraction channel 208 formed therein, a first end of the air extraction channel 208 is communicated with the heating cavity 206. The heating member 202 is accommodated in the heating member 202, and is configured to heat the powder 302 (not shown in FIG. and
The heating device according to the present embodiment can reduce smoke generated with heating as well as an unpleasant odor. Specifically, the fan 204 is mounted on the housing 201, the air extraction channel 208 is provided in the housing 201 connecting the fan and the heating cavity 206, and the filter 205 is provided in the air extraction channel 208. Therefore, while the heating member 202 in the heating cavity 206 heats the powder 302 to be heated attached to the substrate 301, the hot air in the heating cavity 206 can be continuously discharged through the filter 205. Since the filter 205 can filter the dust generated by the heating of the powder 302 to be heated, the smoke and unpleasant odor generated by the dust can be reduced.
In addition, the heating device of this embodiment is typically used by individual users in some confined rooms (e.g., print rooms, studios, etc.). Such rooms generally do not have the extraction system, smoke filtration system, dust removal system, etc. for factory environments. By mounting the fan 204 on the housing 201 of the heating device and connecting the fan 204 and the heating cavity 206 through the air extraction channel 208 in the housing 201, it is possible to realize a miniature filtration system on the heating device itself, which does not require the user to additionally add other filtration systems in the room, and facilitates the user's use.
In this embodiment, the filter 205 may fill the entire air extraction channel 208 to improve the filtration efficiency. Specifically, since the air extraction channel 208 is directly opened in the housing 201, it can be set into various shapes according to practical needs. For example, the air extraction channel 208 may be provided at a corner location of the housing 201. Moreover, the path of the extension of the exaction channel 208 is not required to be long, as long as there is sufficient space to fill the filter 205. Thus, it is possible to easily fill the entire air extraction channel 208 with the filter 205. The filter 205 can be selected with reference to the filter 205 in the first embodiment.
In an embodiment, the heating member 202 may also be plate shaped and laid directly in the heating cavity 206.
The specific technical features described in the above embodiments can be combined in any way as long as no contradiction, and for the sake of unnecessary repetition, various possible combinations are not separately described herein.
Described above are only illustrative of the technical solutions of the present disclosure, and should not be construed as a limitation on the scope of the disclosure. Any modifications or equivalent replacements made by those skilled in the art without departing from the scope of the present disclosure shall fall within the scope of the present disclosure.
