This application claims the benefit of priority from Chinese Patent Application No. 202322656263.5, filed on Sep. 28, 2023. The content of the aforementioned application, including any intervening amendments made thereto, is incorporated herein by reference in its entirety.
This application relates to printing devices, and more specifically to a heat press machine.
The surface of flat carriers, such as clothing and advertisements, may be printed with personalized characters and patterns through heat transfer printing with a heat press machine. Specifically, the characters or patterns are usually printed onto a release material substrate by, for example, an ultraviolet (UV) printer. Furthermore, a solid hot melt adhesive is formed on the surface of the characters or patterns, and is heated by the heat press machine such that the characters or patterns can be thermally transferred onto the surface of the clothing and advertisements.
Furthermore, the formation of the solid hot melt adhesive of the substrate is usually completed in an oven. For example, the hot melt powder is evenly spread by using a powder spreader on the area of the substrate on which the characters or patterns are printed, and then the substrate is heated in an oven to allow the hot melt powder to become a solid hot melt adhesive.
Therefore, the heat transfer printing of characters and patterns involves many devices, such as a UV printer for printing on the substrate, a powder spreader for spreading powder on the substrate surface, an oven for heating the substrate, and a heat press machine for thermal transfer of characters and patterns, which result in large space consumption, and high cost, thereby restricting the promotion and popularization of the heat transfer process among individual consumers.
An objective of the present disclosure is to solve, at least to some extent, one of the existing technical problems. To this end, this application provides a heat press machine, which integrates the function of heating the substrate and the function of thermal transfer, reducing the number of machines.

The heat press machine of this embodiment can be operated according to the following steps.
It can be seen from the above steps that the heat press machine of the present embodiment is capable of integrating the function of heating the substrate 201 and the function of thermal transfer printing, reducing the number of devices. Specifically, by providing the first heating portion 102 below the working platform 107 of the heat press machine, in combination with the second heating portion 104 on the cover 103, the heating power of the heat press machine can be increased to heat the hot melt powder 203. In addition, by alternately using the first tray 105 for carrying the substrate 201 for heating the hot melt powder 203 and the second tray 106 for carrying the transfer object 202 for transferring, the thermal transfer printing can be carried out after the heating of the hot melt powder 203 is completed by using the heat press machine. Further, by forming a cavity 108 in the first tray 105, it prevents the cover 103 from contacting with the substrate 201 (and the hot melt powder 203). Thus, the heat press machine of the present embodiment integrates the function of heating the substrate 201 and the function of performing the thermal transfer printing, which reduces the number of devices and the cost, thereby facilitating the promotion of the thermal transfer printing and the heat press machine among individual consumers.

Furthermore, to inhibit the offset of the first tray 105 or the second tray 106 on the working platform 107, two sides of the working platform 107 in a first direction is each provided with a baffle 114, where the first direction is a direction orthogonal to the direction in which the first tray 105 and the second tray 106 are dismantled. For example, the first tray 105 and the second tray 106 may be placed onto the working platform 107 substantially along a horizontal direction, and the baffles 114 are accordingly arranged on the left and right sides of the working platform 107, respectively. As a result, by providing the baffles 114, the offset of the first tray 105 or the second tray 106 on the working platform 107 can be suppressed, and the positioning accuracy of the first tray 105 or the second tray 106 can be improved.
A linkage mechanism 115 may be provided at the second end of the L-shaped base 101, and the base portion of the linkage mechanism 115 may be swingingly arranged on the base 101. The cover 103 is arranged on a distal end of the linkage mechanism 115, and moves closer to or farther away from the working platform 107 in a swinging manner by the linkage mechanism 115. The distal end indicates an end of the linkage mechanism 115 away from a hand-holding portion of the linkage mechanism 115. The linkage mechanism 115 is not particularly limited, as long as it can allow the cover 103 to be moved closer to or further away from the working platform 107. For example, the linkage mechanism 115 can be a linkage mechanism 115 used in existing heat press machines.
The cover 103 may be made, for example, of metal (such as a metal sheet) that can conduct heat efficiently. Furthermore, to prevent an operator from accidentally touching the cover 103, a heat insulating material is wrapped around the periphery and on the top of the cover 103, respectively, rendering the side of the cover 103 opposite to the working platform 107 visible. A second mounting cavity (not labeled in the drawings) is formed in the cover 103, and the second heating portion 104 is housed in the second mounting cavity. The second heating portion 104 includes a plurality of second heating tubes 116 or second heating wires, and the second heating tubes 116 or second heating wires are accommodated in the cover 103. In this case, the heat from the second heating tubes 116 or the second heating wires provided in the second mounting cavity can be transferred to the working platform 107 via a side of the cover 103 opposite the working platform 107 when the cover 103 is approached toward the working platform 107 and covers the working platform 107.

Alternatively, in some embodiments, the first support plate 117 may not be provided with the cavity 108, but the first buffer 118 may be provided directly on the upper surface of the first support plate 117, where the first buffer 118 is annular and defines the cavity 108 on the surface of the first support plate 117. Similarly, in this embodiment, the thickness of the first buffer 118 is not particularly limited, as long as the cover 103 can press against the first buffer 118 and does not contact with the substrate 201 when the cover 103 is in a working state.
In some embodiments, to improve the heat transfer efficiency of the first heating portion 102, the first support plate 117 is provided with a hollow portion 119 in the position where the cavity 108 is located. For example, the first support plate 117 may be substantially flat, where the cavity 108 is formed in the middle of the first support plate 117, and the hollow portion 119 extends through the cavity 108 along the direction of the thickness thereof. For the sake of support of the first support plate 117, the hollow portion 119 may include a plurality of through-slots 120 extending in a left-right direction, and the plurality of through-slots 120 are spaced apart along a back-front direction.
In addition, to prevent the operator from being burned, the first support plate 117 may be selected from an insulating material such as bakelite. In addition, to strengthen the overall support of the first support plate 117, the first tray 105 may also include a support sheet 121, which is located in the cavity 108 and covers the hollow portion 119. The support sheet 121 may be made of a metal material, such as stainless steel, which is easily conductive to heat, and the thickness of the support sheet 121 is not particularly limited, such as 1-3 mm. As a result, by using a heat-insulating first support plate 117 and providing the hollow portion 119 in the cavity 108, it is possible to prevent the first support plate 117 from scalding the operator while ensuring that the heat from the first heating portion 102 can be transmitted to the cavity 108. Moreover, by placing the support sheet 121 that is easily heat-conductive in the cavity 108, it possible to enhance the overall support force of the first tray 105 and improve the transfer efficiency of heat from the first heating portion 102.
Continuing to refer to
Although the heat (residual heat) from the first heating portion 102 may not necessarily be able to affect the transferring step due to the transferring step consumes less time, to inhibit the rapid transfer of the heat from the first heating portion 102 to the second tray 106 that may affect the transferring step, the second support plate 122 may also be made of a heat-insulating material, such as bakelite. In this case, the heat from the first heating portion 102 can be reduced, and the risk of operator burns can also be reduced.
In addition, in some embodiments, the second tray 106 may also include a heat-insulating member (not shown in the drawings). The heat-insulating member is provided between the second support plate 122 and the second buffer 123. Similarly, the heat-insulating member may be made of bakelite. In this embodiment, the second support plate 122 can also be machined from a sheet metal part.
Although the present disclosure has been described in detail above with reference to the embodiments, one of ordinary skill in the art can still make a variety of changes, modifications, substitutions and variations to these embodiments. It should be understood that those changes, modifications, substitutions and variations made without departing from the principles and purposes of the present disclosure shall fall within the scope of the present disclosure defined by the appended claims.
