Since the printing module, the powder-sprinkling module and the baking module are located in the same housing, the printing equipment in this solution is not a simple stacking of different processing modules, but rather the structure of the printing module, the powder-sprinkling module and the baking module is adaptively adjusted so that the three can be placed in the same housing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0037] This utility model proposes a heat transfer printing device (hereinafter referred to as the printing device), which can be a direct-to-film (DTF) white ink heat transfer printer, an all-in-one heat transfer printer, and an offset white ink heat transfer powder shaker, etc. The printing media for DTF white ink heat transfer printers and offset white ink heat transfer powder shakers is typically heat transfer PET film (PET, "Polyethylene Terephthalate"). The printing media for all-in-one heat transfer printers is typically transfer paper, such as thermal transfer paper or inkjet transfer paper.
[0038] Please see Figures 1 to 3 In one embodiment of the present invention, the printing device includes a housing 100, and a printing module 11, a powder-spreading module 12, and a baking module 13 disposed within the housing 100. The printing module 11 is used to print a pattern on a printing medium 200. The powder-spreading module 12 is used to spread hot melt adhesive powder onto the printing medium 200 so that the hot melt adhesive powder adheres to the pattern. The baking module 13 is used to bake the printing medium 200 so that the hot melt adhesive powder is cured into the pattern. The movement trajectory 101 of the printing medium 200 includes a first trajectory segment 102 and a second trajectory segment 103, and the projections of the first trajectory segment 102 and the second trajectory segment 103 in a first direction are at least partially overlapping. A portion of the printing module 11, the powder-spreading module 12, and the baking module 13 are distributed in the first trajectory segment 102, and another portion is distributed in the second trajectory segment 103.
[0039] During operation, the printing device first inputs a pattern, then prints it through the printing module 11 to form a pattern on the printing medium 200; then, the powder-spraying module 12 sprays hot melt adhesive powder onto the printing medium 200 to form a layer of hot melt adhesive powder on the pattern on the printing medium 200; then, the baking module 13 bakes it to solidify the hot melt adhesive powder onto the pattern, forming a stable and transferable pattern. In this solution, the printing module 11, powder-sprinkling module 12, and baking module 13 are all housed within the housing 100. This means that at least the printing module 11, powder-sprinkling module 12, and baking module 13 are housed within the same housing 100, forming an integrated unit within the same housing. This facilitates the integration of different processing modules into a single device, saving space and eliminating the need for manual or automated material transfer between different devices, thus improving the efficiency of the heat transfer printing equipment. Furthermore, since the printing module 11, powder-sprinkling module 12, and baking module 13 are housed within the same housing 100, the printing device in this solution is not simply a combination of different processing modules. Instead, the structures of the printing module 11, powder-sprinkling module 12, and baking module 13 are adaptively adjusted to allow them to be placed within the same housing 100.
[0040] In some embodiments, the printing device further includes a take-up module 14 and a roll-up module 15, wherein the take-up module 14 is used to take up the printing medium 200 after the hot melt adhesive powder has cured, and the printing medium 200 is rolled up in the roll-up module 15, thereby supplying material to the printing module 11. The take-up module 14 and the roll-up module 15 can both be disposed within the housing 100, in which case they can be installed on an adjacent processing module or installed inside the housing 100; alternatively, the take-up module 14 and the roll-up module 15 can both be disposed outside the housing 100, in which case a hanging structure can be provided on the outer side of the housing 100, and the take-up module 14 and the roll-up module 15 are hung on the hanging structure, thus eliminating the need to reserve installation space for them within the housing 100. In other embodiments, one of the take-up module 14 and the roll-up module 15 can be disposed outside the housing 100, and the other inside the housing 100.
[0041] As the printing medium 200 is processed, it flows sequentially between different processing modules, thus forming a motion trajectory 101. This motion trajectory 101 flows sequentially through the printing module 11, the powder-spreading module 12, and the baking module 13, that is, the printing module 11, the powder-spreading module 12, and the baking module 13 are distributed along the motion trajectory 101.
[0042] The motion trajectory 101 includes a first trajectory segment 102 and a second trajectory segment 103. That is, the motion trajectory 101 can be at least divided into a first trajectory segment 102 and a second trajectory segment 103. A portion of the printing module 11, the powder-spreading module 12, and the baking module 13 are located in the first trajectory segment 102, and another portion is located in the second trajectory segment 103. The first trajectory segment 102 and the second trajectory segment 103 are at least partially overlapped in the projection direction of the first direction. That is, the processing position located in the first trajectory segment 102 and the processing position located in the second trajectory segment 103 are spatially superimposed on each other along the first direction. That is, at least one of the printing module 11, the powder-spreading module 12, and the baking module 13 is superimposed on the arrangement direction of the others. That is, the motion trajectory 101 of the printing medium 200 is bent, which helps to reduce the possibility of the housing 100 being too large in the first direction and is conducive to product miniaturization.
[0043] For ease of explanation, let the first direction be the thickness direction of the printing device. Figure 1 The first direction is the direction along the X-axis, which is the front-to-back direction when the printing device is placed on the ground, with the forward direction being the positive direction and the backward direction being the negative direction; the second direction is the height direction of the printing device. Figure 1 The direction of the Y-axis (i.e., the vertical direction when the printing device is placed on the ground), with the upward direction being the positive direction of the second direction and the downward direction being the negative direction of the second direction; the third direction is the length direction of the printing device ( Figure 1 The direction of the third direction (the direction where the Z-axis is located), that is, the left-right direction when the printing device is placed on the ground, with the left direction being the positive direction and the right direction being the negative direction. However, it is understood that the first direction in this application is not necessarily completely parallel to the X-axis, the second direction is not necessarily completely parallel to the Y-axis, and similarly, the third direction is not necessarily completely parallel to the Z-axis. Furthermore, the third direction, the first direction, and the second direction are not necessarily perpendicular to each other; they may only be set at a certain angle, such as 85°, 75°, 105°, etc. This solution does not impose any restrictions on this.
[0044] For example, the housing 100 has a first space and a second space that overlap in the front-rear direction (first direction). The printing module 11 and the powder-spreading module 12 are both located in the first space, that is, in the first trajectory segment 102. The baking module 13 is located in the second space, that is, in the second trajectory segment 103. The second trajectory segment 103 overlaps with the first trajectory segment 102. In this case, compared with the printing module 11, the powder-spreading module 12 and the baking module 13 being arranged sequentially in the vertical direction (second direction), the height of the printing equipment in this solution is necessarily lower and the layout is easier. Compared with the printing module 11, the powder-spreading module 12 and the baking module 13 being arranged sequentially in the front-rear direction (first direction), the floor area of the printing equipment in this solution is necessarily smaller. Therefore, this solution reduces the floor area required for the receiving position 1005. That is, this solution further optimizes the arrangement of different processing modules inside the printing equipment by optimizing the movement trajectory 101 of the printing medium 200. Of course, in other embodiments, the printing module 11 may be distributed in the first trajectory segment 102, and the baking module 13 and the powdering module 12 may be distributed in the second trajectory segment 103.
[0045] In other embodiments, the first direction may also be Figure 1 The direction of the Y-axis corresponds to the second direction. Figure 1 In the direction of the X-axis, the first trajectory segment 102 and the second trajectory segment 103 overlap vertically. That is, one of the printing module 11, the powder-spreading module 12, and the baking module 13 is arranged vertically with the other two. In other words, in this solution, the arrangement direction of the first trajectory segment 102 and the second trajectory segment 103 is not restricted. As long as at least one of the printing module 11, the powder-spreading module 12, and the baking module 13 overlaps with the others in a certain direction, the movement trajectory 101 of the printing medium 200 will be bent. This will prevent the printing module 11, the powder-spreading module 12, and the baking module 13 from being laid flat in that direction, thereby reducing the possibility that the size of the printing device is too large in a certain direction. All of these are within the protection scope of this solution.
[0046] In other embodiments, the movement trajectory 101 of the printing medium 200 further includes a third trajectory segment, with the take-up module 14 disposed on the third trajectory segment, which may overlap with the first trajectory segment 102; or, the roll-up module 15 disposed on the third trajectory segment, which may overlap with the second trajectory segment 103; or, the take-up module 14 disposed on the first trajectory segment, and the roll-up module 15 disposed on the second trajectory segment. However, if a third trajectory segment exists, and the third trajectory segment overlaps with the first trajectory segment 102 or the second trajectory segment 103, then its overlapping direction is set in the same way as the overlapping direction of the first trajectory segment 102 and the second trajectory segment 103, that is, the movement trajectory 101 of the printing medium 200 extends in an "S" shape.
[0047] Please refer to it again. Figures 1 to 3 In an embodiment of this utility model, the printing module 11 is distributed in the first trajectory segment 102, the baking module 13 is distributed in the second trajectory segment 103, and the printing module 11 and the baking module 13 are arranged at intervals along the first direction. The powder shaking module 12 is disposed on one side of the printing module 11 or the baking module 13 along the second direction, and the first direction and the second direction are arranged at an angle.
[0048] The printing module 11 is located on the first trajectory segment 102, the baking module 13 is located on the second trajectory segment 103, and the powder dispensing module 12 is located on one side of the printing module 11 or the baking module 13 along the second direction. This allows the powder dispensing module 12 to be located at the connection between the first trajectory segment 102 and the second trajectory segment 103, that is, the first trajectory segment 102 and the second trajectory segment 103 intersect at the location of the powder dispensing module 12. In other words, the movement trajectory of the printing medium 200 bends at the powder dispensing module 12, thereby causing the first trajectory segment 102 between the printing module 11 and the powder dispensing module 12 and the second trajectory segment 103 between the powder dispensing module 12 and the baking module 13 to overlap in the first direction, thereby reducing the overall length of the movement trajectory 101 and thus preventing the housing 100 from being too tall.
[0049] The printing module 11 and the baking module 13 are arranged at intervals along the first direction, that is, the printing module 11 and the baking module 13 are opposite each other along the first direction. The powder-spraying module 12 can be located on one side of the printing module 11 along the second direction, or on one side of the baking module 13 along the second direction, or between the printing module 11 and the baking module 13. This can divide the internal space of the housing 100 into a first space layer and a second space layer that are arranged overlappingly in the vertical direction. The printing module 11 and the baking module 13 are located in the first space layer, and the powder-spraying module 12 is located in the second space layer. At this time, the area occupied by the first space layer is often equal to the total area occupied by the housing 100, thereby saving the total area occupied by the housing 100. Furthermore, the printing module 11, the powder-sprinkling module 12, and the baking module 13 are not located on the same straight line, but are roughly arranged in a triangular shape. This not only effectively compresses the size of the housing 100 in a certain direction, but also ensures that the printing module 11, the powder-sprinkling module 12, and the baking module 13 are all relatively close to each other, which helps to improve the rationality of the internal structure of the housing 100.
[0050] In some embodiments, the powder-sprinkling module 12 is located below the baking module 13, meaning the powder-sprinkling module 12 is positioned close to the baking module 13. This means the working path from the powder-sprinkling module 12 to the baking module 13 is shorter than the working path from the powder-dissipating module to the printing module. This allows the pattern with the hot melt adhesive powder adhering to it to be quickly transported to the baking module 13 for baking and curing, reducing uneven patterns caused by accidental hot melt adhesive powder falling during transport and improving the yield rate. Furthermore, the powder-sprinkling module 12 is located below the baking module 13, meaning its height is lower than both the baking module 13 and the powder-sprinkling module 12. Based on the principle of gravity, this arrangement facilitates the powder-sprinkling module 12 in recovering excess hot melt adhesive powder from the printing medium 200. It also simplifies the movement trajectory 101, further reducing the footprint of the housing 100. In other embodiments, the powder-sprinkling module 12 may also be located below the printing module 11; or above the printing module 11 or the baking module 13. It is understandable that the baking module 13 and the printing module 11 are set opposite each other along the first direction, but this does not mean that they are set completely opposite each other; there may be a certain degree of misalignment.
[0051] Furthermore, since the printing module 11, the powder-spraying module 12, and the baking module 13 in this solution are roughly arranged in a triangular shape, and the powder-spraying module 12 is located at the bottom, the bottom of the housing 100 may also have empty space, which can be used to place other structures, such as waste ink cartridges.
[0052] In an embodiment of this utility model, the powder-spreading module 12 includes a powder box 121, a powder-spreading component 122, and a powder-shaking component 123. The powder box 121 is located on one side of the baking module 13 along the second direction. The powder-spreading component 122 is located on the powder box 121 and on the side of the printing medium 200 facing the baking module 13. The powder-shaking component 123 is located on the side of the printing medium 200 away from the powder-spreading component 122. The powder-spreading component 122 is used to spread the hot melt adhesive powder from the powder box 121 onto the printing medium 200. The powder-shaking component 123 is used to shake off excess hot melt adhesive powder from the printing medium 200. The powder box 121 is used to store hot melt adhesive powder and receive hot melt adhesive powder that falls from the printing medium 200.
[0053] The powder dispensing component 122 dispenses hot melt adhesive powder onto the printing medium 200, allowing the powder to remain on the pattern. Excess powder falls off or is shaken off by the powder shaking component 123. The powder cartridge 121 stores the hot melt adhesive powder and can catch excess powder. Therefore, the opening of the powder cartridge 121 faces upwards, and the powder dispensing component 122 is positioned above or above the powder cartridge 121. This allows the powder cartridge 121 to catch falling hot melt adhesive powder when the powder dispensing component 122 dispenses powder onto the printing medium 200, and also to catch powder shaken off by the powder shaking component 123, thus reducing the amount of hot melt adhesive powder scattered to other parts of the housing 100. Therefore, the powder cartridge 121 is typically located at the bottom of the housing 100. The powder dispensing component 122 is located on the side of the printing medium 200 facing the baking module 13; that is, both the powder dispensing component 122 and the baking module 13 are located on the side where the pattern is located, facilitating pattern processing.
[0054] In related technologies, the powder-dispensing component 123 can swing to tap the surface of the printing medium 200, thereby causing the printing medium 200 to vibrate; or the powder-dispensing component 123 can be configured as a powder-dispensing wheel 124, which rolls on the surface of the printing medium 200. At this time, multiple protrusions are provided at intervals along the circumference of the powder-dispensing wheel 124, and the protrusions continuously push up the printing medium 200 to cause the printing medium 200 to vibrate. Therefore, the powder-dispensing component 123 is located on the side of the printing medium 200 away from the powder-spreading component 122, that is, the powder-dispensing component 123 is located on the side away from the pattern, thereby avoiding direct contact between the powder-dispensing component 123 and the pattern.
[0055] In some embodiments, a partition plate 104 is provided between the printing module 11 and the baking module 13, and a powder-dispensing assembly 123 is installed on the side of the partition plate 104 facing the printing medium 200. The partition plate 104 can provide heat insulation. This partition plate 104 not only spatially isolates the printing module 11 and the baking module 13, but also has a heat insulation function, thereby preventing the baking module 13 from baking the printing module 11, reducing mutual interference between the two during operation, and eliminating the need to consider the safety distance between them. This helps to reduce the size of the housing 100, which is beneficial to the miniaturization of the product. Furthermore, the powder-dispensing assembly 123 can also be directly installed on the side of the partition plate 104 facing the printing medium 200, thus eliminating the need for an additional installation structure to install the powder-dispensing wheel 124, further reducing the size of the housing 100.
[0056] In one embodiment, the printing module 11 includes a printing platform 111 and a print head 112 slidably disposed on the printing platform 111 along a third direction, and the discharge side of the printing platform 111 is the side away from the baking module 13, and the third direction is set at an angle with both the first direction and the second direction. The printhead 112 reciprocates upward along the third direction on the printing platform 111, thereby printing a pattern on the printing medium 200. The powder-spraying module 12 is used to receive the printing medium 200 flowing out from the discharge side of the printing platform 111. Therefore, if the discharge side of the printing platform 111 is located close to the baking module 13, the relative distance between the first trajectory segment 102 between the printing module 11 and the powder-spraying module 12 and the second trajectory segment 103 between the baking module 13 and the powder-spraying module 12 may be relatively short. The angle of the corner of the printing medium 200 at the powder-spraying module 12 is very small, which is not conducive to the operation of the powder-spraying module 12 and the setting of the powder-dissipating component 123. Therefore, the discharge side of the printing platform 111 is located away from the baking module 13, thereby expanding the relative distance between the first trajectory segment 102 and the second trajectory segment 103 without increasing the distance between the printing module 11 and the baking module 13, thus facilitating the operation of the powder-dissipating device.
[0057] In an embodiment of this utility model, the housing 100 further includes a take-up module 14, which is distributed in the second track segment 103. The take-up module 14 is used to take up the printing medium 200 after the hot melt adhesive powder has cured. The take-up module 14 is disposed inside the housing 100 and located at the take-up position 1005, thereby hiding the take-up module 14 inside the housing 100, which helps to improve the overall structural integrity of the product and enhances the integration of the housing 100.
[0058] In some embodiments, the receiving module 14 is disposed on the second trajectory segment 103 and on the side of the baking module 13 opposite to the powder-spreading module 12. That is, the receiving module 14 and the powder-spreading module 12 are disposed on opposite sides of the baking module 13, so that the receiving module 14, the baking module 13 and the powder-spreading module 12 are arranged sequentially along the second direction, which helps to simplify and shorten the movement trajectory 101, thereby contributing to the miniaturization of the product. In other embodiments, the receiving module 14, the baking module 13 and the printing module 11 are arranged along the first direction, or the receiving module 14 is disposed on the side of the baking module 13 facing the powder-spreading module 12.
[0059] The housing 100 also includes a roll material module 15, which is distributed in the first track segment 102. The roll material module 15 is used to roll up the printing medium 200 to supply material to the printing module 11, thereby also hiding the roll material module 15 inside the housing 100, which helps to improve the overall structure of the product and enhances the integration of the housing 100.
[0060] In some embodiments, in the second direction, the roll-to-roll module 15 is located on the side of the printing module 11 away from the powder-spraying module 12, that is, the roll-to-roll module 15 is located on the side of the printing module 11 facing the take-up module 14. In other words, the roll-to-roll module 15 and the take-up module 14 are located in the same spatial layer, and the roll-to-roll module 15 and the take-up module 14 can be arranged at intervals along the first direction. Since the working modes of the roll-to-roll module 15 and the take-up module 14 are basically the same, and they often work simultaneously, the roll-to-roll module 15 and the take-up module 14 can be driven by the same drive structure, thereby saving a drive structure and contributing to product miniaturization. Furthermore, the roll-to-roll module 15 is located close to the printing module 11, and the take-up module 14 is located close to the baking module 13, thereby further reducing the movement trajectory 101 of the housing 100.
[0061] Furthermore, to ensure the stability and accuracy of the flow of printing media 200 between the roll-to-roll module 15 and the printing module 11, in some embodiments, a conveying structure, such as a conveyor roller or conveyor belt, is provided between the roll-to-roll module 15 and the printing module 11 to assist in transmission. In other embodiments, conveying structures may also be provided between the printing module 11 and the powder-spreading module 12, and between the baking module 13 and the receiving module 14.
[0062] The housing 100 includes a main housing portion 105 and a mounting cover 106 that can be detachably installed on one side of the main housing portion 105. The printing module 11, the powder dispensing module 12 and the baking module 13 are all located inside the main housing portion 105, and the material receiving module 14 and the roll material module 15 are all located inside the mounting cover 106. The main shell 105 serves as the main body of the outer shell, and its interior is provided with a first mounting space 1051. The printing module 11, the powder-spreading module 12, and the baking module 13 are installed in the first mounting space 1051, thereby facilitating the overall maintenance of the printing module 11, the powder-spreading module 12, and the baking module 13. The mounting cover 106 is located on one side of the main shell 105, thereby forming a second mounting space 1061 with the main shell. The receiving module 14 and the roll-up module 15 are both located in the second mounting space 1061, thereby dividing the processing modules within the shell 100 into modules, which helps to modularize the structure of the shell 100. Since the receiving module 14 and the roll-up module 15 need to continuously load and unload materials, the second mounting space 1061 needs to be continuously opened and closed. Therefore, the mounting slot is detachably installed on one side of the main shell 105. When loading or unloading materials is required, only the mounting cover 106 needs to be removed, which facilitates the operation of the operator.
[0063] In one embodiment, the internal space of the main housing 105 is isolated from the internal space of the mounting cover 106, thereby reducing the direct observation of the internal structure of the housing 100 when the mounting cover 106 is removed, which is also not conducive to the independent operation of each working module, and also reduces the amount of dust falling into the main housing 105. At this time, the main housing 105 has a through hole on the side facing the mounting cover 106, which connects the first mounting space 1051 and the second mounting space 1061. In some embodiments, the mounting cover 106 is located on the upper side of the main housing 105, that is, the receiving module 14 and the winding module 15 are located above the printing module 11 and the baking module 13, thereby facilitating loading and unloading.
[0064] To facilitate ink refilling of the printing module 11, in one embodiment, the housing 100 further includes an ink supply module 16. The ink supply module 16 and the roll material module 15 are located on the same side of the printing module 11. The ink supply module 16 is connected to the printing module 11 to supply ink to the printing module 11. In related technologies, the ink supply module 16 is usually located on the printing platform 111. However, in this solution, the printing module 11 is hidden inside the housing 100, which makes it inconvenient to refill or replace ink in the ink supply module 16. Therefore, the ink supply module is located on the side of the printing module 11 near the roll material module 15, thereby facilitating ink replacement or refilling by the operator. Furthermore, the ink supply module 16 is located on the side of the printing module 11 close to the roll material module 15. Since the roll material module 15 and the take-up module 14 have simpler structures than the printing module 11 and the baking module 13, they may occupy less space. This allows the ink supply components to be placed in the empty space inside the printing device, thereby helping to reduce the overall size of the printing device.
[0065] In this embodiment, the ink supply module 16 includes an ink supply box 161, which can be pulled out and installed in the housing 100, thereby facilitating the operator to change the ink and improving the overall structural integrity of the housing 100.
[0066] To further reduce the overall size of the housing 100, in one embodiment, the printing module 11, the powder-spreading module 12, and the baking module 13 are all arranged along a first direction and / or a second direction, and all three extend along a third direction. The first direction, the second direction, and the third direction are arranged at an angle, meaning that the longer ends of the printing module 11, the powder-spreading module 12, and the baking module 13 are arranged approximately parallel, i.e., the printing module 11, the powder-spreading module 12, and the baking module 13 are arranged in parallel, thereby improving the rationality of their arrangement and helping to reduce the overall size of the main body of the device. It is understood that, to facilitate the insertion of the printing medium 200 into the printing module and the winding of the cured printing medium 200, the roll-up module 15 and the take-up module 14 also extend along a third direction, thereby further reducing the overall size of the housing 100.
[0067] To facilitate maintenance of the housing 100, in this embodiment of the invention, the heat transfer printing equipment further includes a maintenance door 108. The housing 100 has a maintenance opening 107 on one side in the third direction, and the maintenance door 108 is installed on the maintenance opening 107 to open or close it. The housing 100 has two sidewalls spaced apart along the third direction, one of which has the maintenance opening 107. This allows operators to directly observe the printing module 11, the powder-spraying module 12, and the baking module 13 through the maintenance opening 107, facilitating timely maintenance. The maintenance door 108 is installed on the maintenance opening 107 and can open and close it, thus reducing the need for operator intervention while maintaining the structural integrity of the housing 100.
[0068] In some embodiments, the maintenance door 108 and the ink supply module 16 are respectively located on opposite sides of the housing 100, thereby reducing the possibility of interference between the maintenance door 108 and the ink supply module 16 during installation.
[0069] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
