Description
Technical Field
[0001] The utility model relates to the field of screen printing, and particularly to a screen printing pallet device. Background Art
[0002] Screen printing refers to using a screen as a printing plate base and making a screen printing plate with patterns and texts through a photosensitive plate-making method. Screen printing is to stretch a silk fabric, synthetic fiber fabric or metal wire mesh on a screen frame and make a screen printing plate by means of manual lacquer film engraving or photochemical plate-making.
[0003] Screen printing mainly includes simple single-color printing and multicolor overprinting. For single-color printing, it only needs to install the item to be printed once. However, for multicolor overprinting, it is necessary to disassemble, move and replace the printing template multiple times. For example, when printing multi-color patterns on clothes, it is necessary to frequently replace the screen plate and the clothes to print different colors. Due to the frequent movement, disassembly and replacement of the screen printing module, it is difficult to reset the clothes to the position of the previous printing during printing. The large error makes the pattern effect of multicolor overprinting poor and reduces the printing quality. Summary of the Utility Model

[0034] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments, all of which do not depart from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes and not for limiting the present invention.
[0035] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indication of the direction or positional relationship (such as up, down, left, right, front, and back, etc.) is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. When these elements are in the positions shown in the drawings, these descriptions are appropriate. If the description of the positions of these elements changes, the indication of these directions also changes accordingly.
[0036] Please refer to Figure 1 and Figure 2 , this embodiment provides a screen printing pallet device 10. The screen printing pallet device 10 can be a small desktop screen printer and is applicable to ordinary families. The screen printing pallet device 10 of this embodiment includes a base 11, a pallet 12, and a screen printing platform 13. The screen printing platform 13 is placed on the base 11, and the pallet 12 is placed on the screen printing platform 13.
[0037] The base 11 is used to support the screen printing platform 13. The base 11 can be placed on a desktop. The base 11 can facilitate the movement of the screen printing pallet device 10 and is convenient for placing the screen printing pallet device 10 on a desktop or other supporting surfaces. The base 11 is also used to support a screen frame (not shown in the figure), and the screen frame is a template with a screen printing pattern. The screen frame is arranged above the screen printing platform 13.
[0038] The pallet 12 is used to set the workpiece to be processed 20. The workpiece to be processed 20 can be clothes, sailcloth bags, paper, etc. Specifically, in this embodiment, the workpiece to be processed 20 is described by taking clothes as an example.
[0039] The pallet 12 is a rectangular plate-like structure. The pallet 12 includes a front surface 121 and a back surface 122 that are oppositely arranged. The front surface 121 of the pallet 12 faces the screen frame. The position to be printed of the workpiece to be processed 20 is set on the front surface 121 of the pallet 12. The back surface 122 of the pallet 12 faces the screen printing platform 13. Among them, the front surface 121 of the pallet 12 is provided with scale grid lines. The scale grid lines can be used as a reference for and measure the placement position of the workpiece to be processed 20. The scale grid lines can make the placement position of the workpiece to be processed 20 more accurate.
[0040] Please refer to Figure 3 , in other embodiments, a hook 123 can also be provided at one end of the pallet 12. The hook 123 is used to hang the pallet 12 on an external support. After a screen printing is completed on the workpiece to be processed 20 on the pallet 12, the pallet 12 can be directly hung on an external support by using the hook 123, which is convenient for drying.
[0041] The screen printing pallet 12 device 10 further includes a positioning member 14. The positioning member 14 is used to fix the workpiece 20 to be processed on the pallet 12. When the workpiece 20 to be processed is placed on the pallet 12 and multi-color overprinting is performed, during the process of repeatedly removing and installing the pallet 12, the positioning member 14 can fix the workpiece 20 to the pallet 12 to prevent the workpiece 20 from moving and causing printing errors. Therefore, the above screen printing pallet 12 device 10 can achieve the relative position fixation between the pallet 12 and the workpiece 20 through the positioning member 14, preventing the workpiece 20 from shifting and causing printing errors.
[0042] The positioning member 14 can be one or more of a binding strap 141, a clamp 142, a magnetic attraction block 143, a viscous layer (not shown in the figure), and an adhesive strip (not shown in the figure).
[0043] Specifically, in the embodiment, the positioning member 14 can be a binding strap 141. After the workpiece 20 to be processed is placed in place, the binding strap 141 can be used to bind and fix the workpiece 20 to prevent the workpiece 20 from moving during the movement process. The binding strap 141 can be an elastic band and is detachably arranged on both sides of the pallet 12. The setting position of the binding strap 141 and the binding position of the binding strap 141 on the workpiece 20 do not affect normal screen printing.
[0044] Please refer to Figure 4 , in another embodiment, the positioning member 14 can be a clamp 142. Then the clamp 142 can clamp and fix both sides of the workpiece 20 to the pallet 12. The clamp 142 is detachably arranged on the pallet 12. The setting position of the clamp 142 and the clamping position of the clamp 142 on the workpiece 20 do not affect normal screen printing.
[0045] Please refer to Figure 5 , in another embodiment, the positioning member 14 can be a magnetic attraction block 143. The pallet 12 can be a magnetic attraction plate. The magnetic attraction block 143 can be magnetically attracted to the pallet 12. After the workpiece 20 is placed in place, the magnetic attraction block 143 presses on the workpiece 20. The magnetic attraction pressure between the magnetic attraction block 143 and the pallet 12 prevents the workpiece 20 from shifting. Moreover, the pressing position of the magnetic attraction block 143 on the workpiece 20 does not affect normal screen printing operations. The magnetic attraction block 143 can be long and narrow to provide a larger pressing area and press on both sides of the workpiece 20.
[0046] In another embodiment, the positioning member 14 can be an adhesive layer. The adhesive layer at least partially covers the front surface 121 of the pallet 12. The adhesive layer is used for adhesively fixing the workpiece 20 to be processed on the pallet 12. When the workpiece 20 to be processed is disposed on the front surface 121 of the pallet 12, the adhesive layer can generate an adhesive effect with the workpiece 20 to be processed, and the damping force between the workpiece 20 to be processed and the pallet 12 is relatively large, so that the workpiece 20 to be processed cannot move relative to the pallet 12. The adhesive layer can be a 0111 vector removable adhesive layer, and this adhesive layer can withstand a high temperature of 150° and be reused more than 6000 times.
[0047] In another embodiment, the positioning member 14 can also be an adhesive strip. When the workpiece 20 to be processed is a textile, the positioning member 14 can be an adhesive strip such as a magic tape. The adhesive strip can also fix the workpiece 20 to be processed to prevent it from moving and does not affect the normal screen printing operation.
[0048] Please refer to again Figure 1 , the screen printing platform 13 is a rectangular platform, and its surface is a support surface 131. For the convenience of description, the long side direction of the screen printing platform 13 is the longitudinal direction, and the short side direction of the screen printing platform 13 is the transverse direction.
[0049] The screen printing platform 13 is supported on the base 11. One end of the screen printing platform 13 is disposed on the base 11, and there is a gap between the other end of the screen printing platform 13 and the base 11. The screen printing platform 13 is used for carrying the pallet 12. Specifically, in this embodiment, the pallet 12 is detachably disposed on the support surface 131. The pallet 12 is provided with a magnetic attraction portion 124, and the screen printing platform 13 and the pallet 12 are fixedly connected by magnetic attraction. When performing multi-color overprinting, the pallet 12 needs to be removed and installed from the screen printing platform 13 multiple times. By connecting in a magnetic attraction manner, it is convenient for installation and ensures that the pallet 12 can be stably disposed on the screen printing platform 13. In other embodiments, the pallet 12 and the screen printing platform 13 can also be detachably connected by adhesion or the like.
[0050] A positioning structure 15 is provided between the screen printing platform 13 and the pallet 12. The positioning structure 15 is positioned and connected with the pallet 12 to place the pallet 12 at a predetermined position on the screen printing platform 13. This predetermined position is: when the pallet 12 is placed on the support surface 131, the workpiece 20 to be processed can be directly opposite to the printing position of the screen printing frame. When performing multi-color overprinting and the pallet 12 needs to be removed and installed multiple times, if the pallet 12 can be placed at the predetermined position each time, it can ensure that the error between multiple printed patterns is relatively small.
[0051] The positioning structure 15 can include a positioning groove and a convex post. The convex post is received in the positioning groove, and the positioning groove and the convex post are provided between the pallet 12 and the screen printing platform 13.
[0052] Specifically, in this embodiment, the positioning groove 125 is formed on the back surface 122 of the pallet 12. The convex column 132 is provided on the screen printing platform 13, and the convex column 132 protrudes from the support surface 131. In other embodiments, the positioning groove 125 can also be formed on the screen printing platform 13, and the convex column 132 protrudes from the back surface 122 of the pallet 12. As long as the convex column 132 and the positioning groove 125 can cooperate with each other between the pallet 12 and the screen printing platform 13, the pallet 12 can be placed at a predetermined position on the screen printing platform 13.
[0053] The positioning groove 125 can be a groove, and the front surface 121 of the pallet 12 is a uniformly smooth plane. Please refer to Figure 8 , in other embodiments, the positioning structure 15 can also be provided at the end edge of the pallet 12. The convex column 132 is also provided at the end edge of the screen printing platform 12. Then the positioning groove 125 can also be a through hole. Then the positioning groove 125 does not affect the smoothness of the front surface 121 of the pallet 12, ensuring the supporting effect of the pallet 12 on the workpiece 20 to be processed.
[0054] An installation groove 133 is formed on the screen printing platform 13, and the convex column 132 is also installed in the installation groove 133. The top end of the convex column 132 protrudes from the support surface 131 of the screen printing platform 13. Specifically, in this embodiment, the installation groove 133 is long and narrow, and the convex column 132 is movably provided in the installation groove 133. An adjusting knob 134 is provided at the end of the screen printing platform 13. The adjusting knob 134 is in transmission connection with the convex column 132. When the adjusting knob 134 rotates, it can drive the convex column 132 to slide along the installation groove 133. Between the adjusting knob 134 and the convex column 132, structures such as a transmission shaft and a universal joint can be used to achieve the purpose of driving the convex column 132 to move along the installation groove 133 by rotating the adjusting knob 134.
[0055] Moreover, in this embodiment, the pallet 12 can adjust its position along the first direction and the second direction that are perpendicular to each other. Then the installation groove 133 is long and narrow, and the positioning groove 125 is also long and narrow. The extending directions of the positioning groove 125 and the installation groove 133 corresponding to the same convex column 132 are perpendicular to each other. The first direction can be horizontal, and the second direction is longitudinal.
[0056] Specifically, in this embodiment, there can be three adjusting knobs 134, respectively driving and connecting the convex columns 132 of a positioning structure 15. There are three corresponding positioning structures 15. The positioning structure 15 includes a first positioning structure 151 and two second positioning structures 152. Among them, the first positioning structure 151 is provided at the end of the screen printing platform 13. The two second positioning structures 152 are distributed at intervals along the longitudinal direction on one side of the screen printing platform 13.
[0057] The first positioning structure 151 is provided with a first convex post 1321, a first positioning groove 1251, and a first installation groove 1331. The first positioning groove 1251 extends horizontally, and the first installation groove 1331 extends vertically. When the first convex post 1321 is installed in the first installation groove 1331, the first convex post 1321 can move along the first installation groove 1331, thereby driving the pallet 12 to move and adjust longitudinally.
[0058] The second positioning structure 152 is provided with a second convex post 1322, a second positioning groove 1252, and a second installation groove 1332. The second positioning groove 1252 extends vertically, and the second installation groove 1332 extends horizontally. When the second convex post 1322 is installed in the second installation groove 1332, the second convex post 1322 can move along the second installation groove 1332, thereby driving the pallet 12 to move and adjust horizontally.
[0059] Therefore, for the settings of the positioning groove 125 and the installation groove 133 of the positioning structure 15, the pallet 12 can be positioned and adjusted in two perpendicular directions. During multi-color overprinting, when the workpiece 20 to be processed moves and causes a certain error, in order to reduce the error, by adjusting the position of the pallet 12, the processing position of the workpiece 20 to be processed can be ensured to be accurate, improving the accuracy of multi-color overprinting.
[0060] It can be understood that the first positioning structure 151 and the second positioning structure 152 can be one or more, and are specifically set according to design requirements, as long as the pallet 12 can be positioned and set on the screen printing platform 13.
[0061] Now, in combination with the screen printing process of the workpiece 20 to be processed, the above-mentioned screen printing pallet 12 device 10 will be described. For the convenience of description, the workpiece 20 to be processed is taken as an example of a piece of clothing:
[0062] First, put the pallet 12 into the clothing, so that the printing surface of the clothing is above the front surface 121 of the pallet 12. Use the positioning member 14 to position the clothing on the pallet 12. For example, use the binding straps 141 to bind both sides of the clothing, and the binding straps 141 fix and position the clothing and the pallet 12.
[0063] Then, put the clothing over the screen printing platform 13, so that the screen printing platform 13 is also received in the clothing, and the screen printing platform 13 can abut against the lower side of the pallet 12. The pallet 12 is carried on the screen printing platform 13.
[0064] The pallet 12 is positioned with the screen printing platform 13 through a positioning structure, so that the pallet 12 is placed at a predetermined position on the screen printing platform 13. That is, the convex posts 132 of the screen printing platform 13 are correspondingly snapped into the positioning grooves 125 on the back surface 122 of the pallet 12. Then, the pallet 12 and the screen printing platform 13 are fixed by magnetic attraction. The clothes on the pallet 12 are subjected to and completed the first screen printing. The pallet 12 and the clothes are taken down together, and the screen printing frame is replaced to prepare for subsequent multiple screen printings.
[0065] When subsequent multiple screen printings are carried out, the pallet 12 and the clothes need to be installed on the screen printing platform 13 again. Then, the convex posts 132 of the screen printing platform 13 are snapped into the corresponding positioning grooves 125 of the pallet 12 again. Then, the pallet 12 is set at the predetermined position again without deviation, ensuring the accuracy of the positions of subsequent multiple screen printings, thereby improving the printing quality of multicolor overprinting.
[0066] During this process, if it is found that the position to be printed on the clothes has a slight displacement, then the adjustment knob 134 is adjusted. When it is necessary to move the pallet 12 longitudinally, the adjustment knob 134 corresponding to the first convex post 1321 is adjusted. When it is necessary to move the pallet 12 transversely, the adjustment knob 134 corresponding to the second convex post 1322 is adjusted. By using the movement of the convex posts 132, the position of the pallet 12 is driven to be adjusted, so that the position to be printed on the clothes remains accurate. Therefore, even if multiple subsequent screen printings are required, the operations of assembling the pallet 12 and adjusting the pallet 12 can be repeated to keep the position to be printed on the clothes accurate, thereby improving the screen printing quality of multicolor overprinting.
[0067] The above embodiments are only illustrative examples of the structure. The structures in each embodiment are not fixedly combined structures. Without structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used.
