[0030] In the description of this utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference Figures 1 to 4 According to some embodiments of the present invention, the thermal sublimation transfer device includes a chassis and a first heating module 10; wherein the chassis includes a box body 20 and a box cover 30, the top of the box body 20 is provided with an opening 210, the box cover 30 is rotatably connected to the top of the box body 20, and can open or close the opening 210; the first heating module 10 includes a slot 110 and a first heating element, the top of the slot body 110 is provided with a receiving slot 111 for receiving the product to be printed; the first heating element is provided in the slot The box body 110 is used to heat the box body 110, and then heat the product and film placed in the receiving groove 111; wherein, the first heating module 10 is arranged in the box body 20, and the top is exposed at the opening 210; a baking film groove 410 is provided in the box body 20, and the baking film groove 410 is located at the lower side of the first heating module 10, and the side of the box body 20 is formed with an inlet and outlet 220 connected to the baking film groove 410, and then the film that has just completed pattern printing can be placed in the baking film groove 410 through the inlet and outlet 220.

[0033] It should be understood that, since the baking slot 410 is arranged at the lower side of the groove 110 in the box 20, and the inlet and outlet 220 communicating with the baking slot 410 is arranged at the side of the box 20, after the printing of the pattern on the film sheet is completed, the film sheet just completed the printing of the pattern can be placed in the baking slot 410 through the inlet and outlet 220, and the heat emitted by the groove 110 and the first heating element is used to assist the baking of the film sheet, so that the pattern ink on the film sheet can be quickly dried, and then the film sheet can participate in the heat transfer printing faster, thereby facilitating the improvement of the transfer efficiency.

[0034] When the pattern transfer is performed, the product to be transferred can be placed in the containing groove 111, then the film sheet with the printed pattern is laid on the product, and then the box cover 30 is covered, so that the groove 110 and the product and the film sheet in the groove 110 are heated by the first heating element to transfer the pattern of the film sheet to the product.

[0035] It can be understood that the box 20 of the heat transfer printing equipment is also provided with a control panel and other components (for example, a vacuum pump and a negative pressure gauge to be mentioned below), in order to reduce the influence of the high temperature generated by the first heating module 10 on the work of other components during the transfer, in some embodiments, with reference to Figure 3 , the box 20 is also provided with a partition plate 230, and the partition plate 230 divides the upper part of the box 20 to form a transfer chamber 240, the opening 210 communicates with the transfer chamber 240, and the first heating module 10 is arranged in the transfer chamber 240, so as to isolate the first heating module 10 in the transfer chamber 240, thereby reducing the heat diffusion to the remaining areas of the box 20 except the transfer chamber 240.

[0036] In addition, since the first heating module 10 is relatively heavy, in order to effectively support the first heating module 10 and reduce the heat conduction of the first heating module 10 to the other areas of the box 20 except the transfer chamber 240 through the partition plate 230, in some embodiments, with reference to Figure 3A support frame 250 is provided within the housing 20. The support frame 250 passes through the partition 230 and is connected at its bottom to the bottom plate 260 of the housing 20. The first heating module 10 is disposed on top of the support frame 250. The support frame 250 allows the first heating module 10 to be suspended within the transfer chamber 240. This prevents the first heating module 10 from contacting the partition 230, thereby preventing the first heating module 10 from unloading its weight onto the partition 230 and damaging the partition 230. This also effectively prevents the first heating module 10 from transferring heat to the partition 230, thereby reducing the amount of heat transferred to areas of the housing 20 other than the transfer chamber 240 via the partition 230. Furthermore, because the first heating module 10 is suspended within the transfer chamber 240 via the support frame 250, a space 241 is formed between the bottom of the first heating module 10 and the partition 230, facilitating the placement of the film baking groove 410 at the bottom of the first heating module 10.

[0037] It is understood that in some of these embodiments, reference Figure 3 and Figure 5 The sublimation transfer equipment also includes a tray 40, which is arranged in the partition space 241 and connected to the partition 230. A baking film groove 410 is formed on the side of the tray 40 facing the first heating module 10; it should be understood that by arranging the baking film groove 410 on the tray 40 and arranging the tray 40 in the partition space 241 at the bottom of the first heating module 10, it can be beneficial for the first heating module 10 to better transfer heat to the film in the baking film groove 410, so as to improve the drying efficiency of the ink on the film.

[0038] It should be understood that to provide stable support for the first heating module 10 and prevent the support racks 250 from interfering with the installation of the tray 40 in the space 241, two support racks 250 are provided and spaced apart along the length of the first heating module 10. The two support racks 250 are used to support the first heating module 10 at both ends in the lengthwise direction, with the tray 40 positioned between the two support racks 250. Specifically, the tray 40 includes a tray body and flanges 420 disposed around the tray body. The flanges 420 adjacent to the inlet and outlet 220 are folded downward, while the remaining three flanges 420 are folded upward. The three upwardly folded flanges 420 and the tray body together form a film baking groove 410 having notches on both the top and the side facing the inlet and outlet 220. This not only facilitates the entry and exit of film into and out of the baking groove 410, but also facilitates better heat transfer from the first heating module 10 to the film in the baking groove 410. It should be understood that the baking film groove 410 can be fixedly connected to the partition 230 by fasteners passing through the plate body and the lower folded flange 420.

[0039] It can be understood that, in order to better heat the product to be transferred in the accommodating groove 111 and the film in the film baking groove 410, in some embodiments, the first heating member is arranged on the bottom wall of the groove body 110 and above the film baking groove 410, so that the first heating member can quickly heat the bottom wall of the groove body 110 when working, so that the heat can be quickly transferred to the product carried on the bottom wall and the film attached to the product; and since the heating member and the bottom wall of the groove body 110 are both located on the upper side of the film baking groove 410, the film baking groove 410 can be directly opposite to the area in the first heating module 10 which has relatively higher temperature and relatively larger amount of heat outward diffusion, thereby also being beneficial to the ink on the film being dried more quickly. For example, referring to Figure 4 In an embodiment, the bottom wall of the groove body 110 is provided with a mounting hole 114 extending along the width direction of the groove body 110, and the first heating member is an electric heating tube (not shown in the figure), which is mounted in the mounting hole 114 and located directly above the film baking groove 410.

[0040] It can be understood that, in order to enable the film to be more closely attached to the surface of the product, in some embodiments, the heat transfer printing equipment further comprises a vacuum generating device 50 and a vacuum pipeline (not shown in the figure), and the bottom wall of the groove body 110 is provided with a vacuum hole, which communicates with the accommodating groove 111. The vacuum generating device 50 communicates with the vacuum hole through the vacuum pipeline, so that after the box cover 30 is closed, the air in the accommodating groove 111 can be pumped out through the vacuum pipeline and the vacuum hole by starting the vacuum generating device 50, so that the air between the film and the product can also be pumped out, and the film is closely attached to the product under the action of negative pressure, thereby improving the quality of pattern transfer.

[0041] It should be understood that, in an embodiment, referring to Figure 3 and Figure 4 , the vacuum generating device 50 is a vacuum pump, and the vacuum hole includes a plurality of air suction holes 112 arranged on the groove bottom of the accommodating groove 111 and an air channel arranged on the bottom wall of the groove body 110 and communicating with each air suction hole 112. The air channel forms an air outlet 113 on one side surface of the groove body 110 and connects one end of the vacuum pipeline through the air outlet 113, the vacuum pipeline passes through the partition plate 230, and the other end of the vacuum pipeline is connected to the vacuum pump; and in order to detect the air pressure in the accommodating groove 111, the heat transfer printing equipment further comprises a negative pressure gauge 60 for measuring the air pressure in the vacuum pipeline or the air channel communicating with the accommodating groove 111, thereby obtaining the air pressure in the accommodating groove 111. It should be understood that the vacuum pump and the negative pressure gauge 60 are arranged in the box body 20 and located in the area outside the transfer chamber 240.

[0042] It can be understood that, in order to improve the heating effect of the product to be transferred and the film attached to the product, and to make the film and the product in the containing groove 111 more evenly heated during the product transfer, in some embodiments, the second heating module 310 is arranged on the side of the box cover 30 facing the containing groove 111, so that after the box cover 30 is closed, the second heating module 310 on the box cover 30 is directly above the product to be transferred and the film, so that the product and the film in the containing groove 111 can be heated from the bottom by the groove body 110 and the first heating element, and can also be heated from the top by the second heating module 310, so that the heating and warming speed can be faster, and the heating is more uniform.

[0043] It should be understood that, in some embodiments, the second heating module 310 includes a heat-conducting block and a second heating element, wherein the second heating element is arranged in the heat-conducting block and is used to heat the heat-conducting block to more evenly transfer heat to the product and the film through the heat-conducting block. It should be understood that, in order to facilitate the arrangement of the second heating element in the heat-conducting block, the second heating element can be selected as an electric heating tube.

[0044] It can be understood that, in order to make the product and the film in the containing groove 111 more evenly heated, in addition to the second heating module 310 being arranged on the box cover 30, in some embodiments, hot air can also be introduced into the containing groove 111 to heat the product and the film all around. For example, in one embodiment, referring to Figures 6 to 8 , the heat transfer printing equipment further comprises a hot air heating module (not shown in the figure) and an air guide assembly 70, both of which are arranged in the box body 20. The air guide assembly 70 is provided with a first air guide channel 710, the air inlet end of the first air guide channel 710 is communicated with the air outlet of the hot air heating module, the air outlet end of the first air guide channel 710 extends to the top of the box body 20 and is located on one side of the box cover 30; the box cover 30 is provided with a second air guide channel 320, the air inlet end of the second air guide channel 320 extends to the side of the box cover 30 connected with the box body 20, and when the box cover 30 is in the closed state, the air inlet end of the second air guide channel 320 is opposite and communicated with the air outlet end of the first air guide channel 710, and the air outlet end of the second air guide channel 320 is communicated with the containing groove 111, so that the hot air generated by the hot air heating module can enter the containing groove 111 through the first air guide channel 710 and the second air guide channel 320 in sequence, and the hot air can heat the product and the film all around after filling the heat-conducting groove.

[0045] It should be understood that, in some embodiments, the hot air heating module includes a fan, a heating element and an air guide cover, the heating element is arranged on the air outlet side of the fan, and the air guide cover and other air guide elements are used to guide the hot air formed by the heating element to the air inlet end of the first air guide channel 710.

[0046] It can be understood that, in some embodiments, referring to Figure 6 , the box cover 30 is provided with a diffusion groove 330 on the side facing the containing groove 111, and the air outlet end of the second air guide channel 320 communicates with the diffusion groove 330, so that the hot air flowing out of the second air guide channel 320 is first diffused in the diffusion groove 330 with a larger cross section, and then enters the containing groove 111 after diffusion, so that the hot air can flow more uniformly to each position of the containing groove 111, further improving the uniformity of heating the products and the film in the containing groove 111.

[0047] It can be understood that, in order to avoid the hot air from leaking out to the outside between the air outlet side of the first air guide channel 710 and the air inlet side of the second air guide channel 320, thereby improving the utilization rate of heat energy, in some embodiments, the heat transfer printing equipment further comprises an elastic sealing pad (not shown in the figure), which is arranged at the air outlet end of the first air guide channel 710 and abuts against the box cover 30. Since the elastic sealing pad has good elasticity and flexibility, it can not only prevent air leakage between the air guide assembly 70 and the box cover 30 when the box cover 30 is in the closed state, but also can deform with the opening and closing of the box cover 30, thereby reducing the hindering effect on the opening and closing of the box cover 30.

[0048] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the present application, and the scope of the present application is defined by the claims and their equivalents.
