1. Field of the Invention
This invention relates to a movable spray painting stand, particularly to one able to be moved around freely and having a function of filtering the exhaust and odor of paint produced in a spray painting process, conforming to environmental protection and ensuring workers' health.
2. Description of the Prior Art
Nowadays, most people have become do-it-yourself fans. They prefer to make, assemble and beautify things themselves so as to attain sense of fulfillment and sense of gratification. Spray painting is one of do-it-yourself work liked by people.
However, conventional spray-painting work always produces exhaust and odor of paint, not only affecting workers' health but also causing pollution to environment. A common family does not have a room to be exclusively used for doing spray painting work; therefore some of such work has to be done in a spray painting workshop, thus unable to obtain pleasure of DIY and possible to cause much inconvenience.
The objective of the invention is to offer a movable spray-painting stand having a wind-exhausting device and a filtering device assembled on a worktable having its four legs respectively provided with a caster. The wind-exhausting device has an air inlet communicating with the wind outlet of the filtering device. A separating device is provided at its wind inlet of the filtering device for forming a spray-painting space enclosed by blocking plates. A collapsible work frame is pivotally assembled with the work table under the separating device, able to be moved in the spray painting space after articles to be spray painted are placed on its upper plate.
The spray painting stand in the present invention can be moved around freely, and the wind-exhausting device is able to suck the exhaust and the odor of paint produced during spray painting into the filtering device to be filtered and, after filtered, the clean air is exhausted out through the wind-exhausting device, preventing air pollution, achieving an effect of environmental protection and ensuring workers' health.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a movable spray painting stand in the present invention, as shown in
The worktable 10 has four legs 12 fixed under its tabletop 11, having a caster 13 assembled at the lower end of each leg 12.
The wind-exhausting device 20 assembled on the flat stand 11 of the worktable 10 is composed of a motor 21, a cover 22 and a blade wheel 23. The blade wheel 23 is assembled on the rotating shaft 211 at the front end of the motor 21 to be driven to rotate. The cover 22 is covered around the entire blade wheel 23, having its front side bored with an air inlet 221 and its topside bored with an air outlet 222.
The wind-power indicator 30, as shown in
The filtering device 40 includes a machine housing 41, a first filtering plate 42 and a second filtering plate 43. The machine housing 41 has. its rear half portion formed with a rectangular body and its front half portion formed with a trumpet-shaped body able to increase an air sucking area and enlarge a spray painting space. The filtering device 40 assembled on the table top 11 of the work table 10 has its front end formed with a wind inlet 411, the upper side of its intermediate portion formed with a cut groove 412 and its rear end formed with a wind outlet 413 communicating with the air inlet 221 of the cover 22 of the wind-exhausting device 20. The first filtering plate 42 is assembled at the location of the wind inlet 411 of the machine housing 41, able to be disassembled from the machine housing 41, and the second filtering plate 43 is fitted in the cut groove 412 of the machine housing 41, able to be pulled out of the cut groove 412. The first and the second filtering plate 42, 43 are made of active carbon screen and non-woven fabric .
The separating device 50 consists of an upper blocking plate 51 and two side blocking plates 52. The upper blocking plate 51 is assembled on the topside of the machine housing 41 of the filtering device 40 and positioned above the wind inlet 411, expanding forward in a flaring shape. The two side blocking plates 52 are respectively and pivotally positioned at the opposite sides of the wind inlet 411 of the machine housing 41, respectively expanding outward gradually. The two side blocking plates 52 have their upper edges respectively connected with the upper blocking plate 51 together to form a spray painting space 53. Further, the two side blocking plates 52 respectively have the outer lower end provided with an elastic insert member 521 able to be elastically moved downward or pulled upward. Furthermore, the upper blocking plate 51 and the two side blocking plates 52 are respectively provided with a frame 511, 522 attached thereon with a cloth screen 512, 523.
The work frame 60 consists of plural feet 61 and an upper plate 62 positioned on the lower supporter 61, which are able to be collapsed and laid under the stand 62. The upper plate 62 is used for placing articles to be spray painted, having its inner end pivotally assembled with two opposed legs 12 of the work table 10 and able to be collapsed inward. The upper plate 62. of the work frame 60 has the outer ends of its opposite sides respectively bored with a positioning hole 621 for the elastic insert member 521 of the two side blocking plates 52 to be inserted and positioned therein to stabilize the two side blocking plates 52 on the work frame 60.
In operating, as shown in
If the first and the second filtering plate 42, 43 of the filtering device 40 have been used for a period of time, they are likely to be stuck with dust and particles of paint and become clogged to lower their sucking force and filtering capability. Judging from the location of the index hand 34 of the wind-power indicator 30, a user is able to know the strength of air exhausted out through the air outlet 222 of the wind-exhausting device 20 and then judge whether or not the first and the second filtering plate 42, 43 are clogged and need to be replaced with new ones or cleaned, always maintaining an excellent effect of filtration.
As can be understood from the above description, this invention has the following advantages.
1. It is provided with the wind-exhausting device 20 to produce a sucking force, and the filtering device 40 with the first and the second filtering plate 42, 43 to carry out multiple filtration, able to effectively filter the exhaust and the odor of paint produced in a spray painting process to prevent environment from polluted and ensure workers' health.
2. The work table 10 has its four legs respectively provided with a caster 13 to enable the work table to be moved around freely, and both the separating device 50 and the work frame 60 are collapsible, facilitating operating and suitable for a common family or a small-sized workshop to use.
3. The wind-power indicator 30 is able to indicate the strength of exhausted wind so as to remind a user whether or not the first and the second filtering plate 42, 43 of the filtering device 40 are clogged and need to be replaced with new ones or cleaned, able to maintain an excellent effect of filtration.
4. The first filtering plate 42 is able to be disassembled from the filtering device 40, and the second filtering plate 43 can be pulled out of the cut groove 412 of the filtering device 40; therefore, both the first and the second filtering plate 42, 43 can easily be assembled or disassembled to be replaced with new ones or cleaned.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
