[0028] In an embodiment of the present application, as shown in Figures 1-4 A printing jig for screen printing is provided, which comprises a base 10, a limiting seat 20 and a printing frame 30. The base 10 is centrally provided with a cavity. The limiting seat 20 is arranged in the cavity and detachably connected to the base 10 at both ends. The limiting seat 20 is provided with a limiting groove corresponding to the outer surface of the product. One end of the printing frame 30 is rotatably arranged on one end of the base 10 and located above the limiting seat 20, used for printing the product on the limiting seat 20.
[0029] By setting the limiting seat 20 and the limiting groove, the product to be printed is placed in the limiting groove, so that the product can be quickly and accurately positioned at the printing position, without the need for tedious steel mesh 32 debugging based on the product as before, greatly reducing the time of repeated calibration and adjustment. At the same time, through the detachable connection of the limiting seat 20 at both ends and the base 10, the limiting seat 20 can be replaced according to the size and shape of different products, without the need to replace the entire base 10, improving the versatility of the jig, so that the same base 10 can adapt to the printing needs of a variety of different products, thereby reducing production costs and storage space requirements.
[0030] Preferably, the limiting seat 20 is provided with a fixed part 21 extending outward at both ends. The fixed part 21 is detachably connected with the base 10. Through the detachable connection between the fixed part 21 and the base 10, the replacement of the limiting seat 20 becomes simple and fast to adapt to the printing of different products, thereby improving the versatility of the jig.
[0031] Further, the fixed part 21 and the base 10 are provided with a connecting block 22. The fixed part 21 is provided with a first connecting hole 23. The connecting block 22 is provided with a second connecting hole 24 coaxially arranged with the first connecting hole 23. The fixed part 21 is provided with a first locking member. One end of the first locking member is sequentially threaded from top to bottom through the first connecting hole 23, the second connecting hole 24, and is threadedly connected with the second connecting hole 24. In this embodiment, the first locking member is a locking bolt or a locking screw, and the connecting block 22 on the base 10 is detachably connected with the fixed part 21 through the first locking member, so that the replacement of the limiting seat 20 becomes simple and fast to adapt to the printing of different products, thereby improving the versatility of the jig.
[0032] Further, the connecting block 22 is provided with a third connecting hole 25. The base 10 is provided with a fourth connecting hole coaxially arranged with the third connecting hole 25. The base 10 is provided with a second locking member. The second locking member is sequentially threaded from bottom to top through the fourth connecting hole and the third connecting hole 25, and is threadedly connected with the third connecting hole 25. In this embodiment, the second locking member is a locking bolt or a locking screw, and the connecting block 22 is detachably connected with the base 10 through the second locking member, and the limiting seat 20 is replaced to adapt to different connecting spaces, thereby further improving the versatility of the jig. At the same time, the damaged connecting block 22 can also be replaced to ensure the stable connection of the limiting seat 20, thereby improving the service life of the jig.
[0033] Preferably, the printing frame 30 includes an upper positioning frame 31, a steel mesh 32, and a lower positioning frame 33. One end of the lower positioning frame 33 is rotatably mounted on the base 10. The upper positioning frame 31 is fixedly mounted on the lower positioning frame 33. The steel mesh 32 is disposed between the upper positioning frame 31 and the lower positioning frame 33. By setting the upper positioning frame 31 and the lower positioning frame 33, the steel mesh 32 can be quickly and stably installed between the upper positioning frame 31 and the lower positioning frame 33, improving the installation efficiency of the steel mesh 32 and facilitating its replacement, thus ensuring the normal use of the printing frame 30.
[0034] Furthermore, the lower positioning frame 33 has four upwardly protruding first limiting blocks 34 at its four corners. A second limiting block 35 is provided between two adjacent sets of first limiting blocks 34. The bottom of the upper positioning frame 31 has a first limiting groove corresponding to the first limiting block 34 and a second limiting groove corresponding to the second limiting block 35. The steel mesh 32 has a first positioning groove corresponding to the first limiting block 34 and a second positioning groove corresponding to the second limiting block 35. The first limiting block 34 has an "L" shape, and the second limiting block 35 has an "I" shape. By setting the first limiting blocks 34 and the second limiting blocks 35, the steel mesh 32 can be quickly positioned on the lower positioning frame 33, simplifying the installation steps of the steel mesh 32. At the same time, it also avoids printing quality problems caused by the steel mesh 32 not being securely fixed.
[0035] Furthermore, an upper hinge 40 is provided on one side of the lower positioning frame 33. A lower hinge 41 is provided on one side of the base 10. The upper hinge 40 and the lower hinge 41 are located on the same side and are connected by a connecting shaft 42. By providing the upper hinge 40 and the lower hinge 41, the printing frame 30 can be easily opened and closed, facilitating the placement and removal of products and improving printing efficiency.
[0036] Furthermore, the upper positioning frame 31 is provided with an opening handle 36 on the side near the upper hinge 40 for opening the positioning frame. By providing the opening handle 36, the upper positioning frame 31 can be easily opened, reducing the physical exertion of the operator.
[0037] Furthermore, the upper positioning frame 31 is provided with an auxiliary opening lever 37 on the side away from the upper hinge 40. By setting the opening lever 37, the upper positioning frame 31 can be opened more easily with the cooperation of the opening handle 36 and the lever 37, further reducing the physical exertion of the operator.
[0038] The above are only preferred embodiments of the present application, and only the technical principles of the present application are specifically described, and these descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanation herein, any modification, equivalent replacement and improvement made within the spirit and principles of the present application, and other specific embodiments of the present application that can be conceived by those skilled in the art without creative labor, should be included in the protection scope of the present application.
