Technical Field

[0001] The utility model relates to the technical field of composite screen printing, in particular to a multi-color composite screen printing component. Background Art

[0002] Multi-color composite screen printing is a screen printing technology. Screen printing is to transfer ink through the mesh holes of the screen onto the printing substrate to form graphics and texts by extrusion of a squeegee. On this basis, multi-color composite screen printing uses multiple screens (each screen corresponding to one color) to print multiple different colors of ink on the same printing substrate in sequence or simultaneously, so as to combine complex and colorful patterns.

[0003] For the existing multi-color composite screen printing, the screen needs to be frequently replaced. Since it involves printing of multiple colors, it is difficult to ensure accurate registration of the patterns of each color, and it requires high-precision positioning and skilled operation techniques by workers, wasting a large amount of time for positioning and replacement. To solve the foregoing problems, a multi-color composite screen printing component is provided. Summary of the Utility Model

[0018] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0019] Existing multi-color composite screen printing requires frequent replacement of the screen. Since it involves printing multiple colors, it is difficult to ensure that the pattern of each color is accurately registered. It requires workers to perform high-precision positioning and skilled operation techniques, wasting a lot of time on positioning and replacement.

[0020] To resolve this issue, see Figure 1-4 , a multi-color composite silk-screen printing component, comprising: a positioning component 1, the positioning component 1 comprises a supporting barrel 11, a motor 111 is fixed in the supporting barrel 11, a disc 12 is fixed at the output end of the motor 111, a positioning disc 121 is fixed on the upper end surface of the disc 12, a cylinder 122 is fixed on the upper end surface of the disc 12, a turntable 13 is rotatably provided on the supporting barrel 11, a sleeve 14 is fixed on the lower end surface of the turntable 13, the sleeve 14 passes through the top of the supporting barrel 11, an intermittent disc 15 is fixed at the bottom of the sleeve 14, at least three groups of U-shaped grooves 151 are provided on the intermittent disc 15, an arc groove 152 is provided in the middle of every two groups of U-shaped grooves 151, and the arc groove 152 is intermittently rotatably connected to the positioning disc 121, at least three groups of supporting frames 16 are fixed around the turntable 13, a connecting frame 17 is rotatably provided on the supporting frame 16, a screen frame 18 is detachably fixed on the connecting frame 17, a silk screen 19 is fixed in the screen frame 18;

[0021] The rotating assembly 2 is fixedly mounted on the bottom of the support frame 16 .

[0022] During use, different silk screens are fixedly installed on the connecting frame 17 in sequence. After the silk screen printing is completed, the staff starts the motor 111. The motor 111 drives the disc 12 to rotate one circle. The disc 12 drives the intermittent disc 15 to rotate intermittently through the positioning disc 121, the cylinder 122, the U-shaped groove 151 and the arc groove 152. The intermittent disc 15 drives the turntable 13 to rotate intermittently through the sleeve 14. The turntable 13 drives the connecting frame 17 to rotate intermittently through the support frame 16. The connecting frame 17 drives the silk screen 19 to rotate intermittently through the screen frame 18. The silk screen 19 that has been silk-screened is turned away through the intermittent rotation, and the next silk screen 19 is turned in a more orderly manner for the next silk screen printing.

[0023] The rotating assembly 2 includes a barrel 21 and a rack 23. The barrel 21 is fixedly provided at the bottom of the support frame 16. An elastic member 22 is fixedly provided inside the barrel 21. A rack 23 is slidably provided inside the barrel 21. The other end of the elastic member 22 is fixedly connected to the rack 23. A gear 24 is fixedly provided on the connecting frame 17, and the gear 24 is meshed with the rack 23 respectively.

[0024] During use, the screen mesh 19 that is rotated is pulled upward to move the rack 23. The rack 23 moves upward to stretch the elastic member 22 inside the cylindrical barrel 21. The upward movement of the rack 23 drives the connecting frame 17 to rotate through the gear 24. The connecting frame 17 drives the screen mesh 19 to rotate through the screen frame 18, making the screen mesh 19 horizontal for screen printing. When the screen printing is completed, release the rack 23. The elastic member 22 contracts and pulls the rack 23 downward. The rack 23 drives the gear 24 to rotate. The gear 24 stands up through the connecting frame 17 and is perpendicular to the support frame 16. The connecting frame 17 drives the screen mesh 19 to stand up through the screen frame 18, enabling it to stand up during rotation to save space.

[0025] A support rod 3 is fixedly provided on the support barrel 11. An electric push rod 31 is fixedly provided on the support rod 3. A pull plate 32 is fixedly provided at the piston rod end of the electric push rod 31. A U-shaped frame 33 is fixedly provided on the rack 23.

[0026] During use, when it is necessary to pull the rack 23, start the electric push rod 31 to retract the piston rod. The electric push rod 31 drives the pull plate 32 to pull the rack 23 upward through the U-shaped frame 33. When it is necessary to rotate the turntable 13, push the pull plate 32 at the piston rod end of the electric push rod 31. The rack 23 descends to the bottom, making the pull plate 32 located in the middle of the U-shaped frame 33. When the turntable 13 drives the rack 23 to rotate intermittently through the cylindrical barrel 21, the rack 23 drives the U-shaped frame 33 to rotate intermittently. After rotation, the next U-shaped frame 33 is rotated to the position of the pull plate 32, making the pull plate 32 located in the middle of the next U-shaped frame 33, and repeat the operation in this way.

[0027] There is an arc-shaped groove notch on the side of the positioning disk 121, which is crescent-shaped. The cylinder 122 is located at the edge of the disk 12 facing the arc-shaped groove notch of the positioning disk 121.

[0028] During use, the disk 12 drives the intermittent disk 15 to rotate a certain angle through the cylinder 122 and the U-shaped groove 151. The positioning disk 121 and the arc-shaped groove 152 position the intermittent disk 15, making the angle of each rotation fixed. The arc-shaped groove notch on the side of the positioning disk 121 enables the intermittent disk 15 to rotate.

[0029] The support rod 3 is located at the center of the support barrel 11. The support rod 3 passes through the turntable 13. The support rod 3 is located at the center of the sleeve 14.

[0030] During use, the support rod 3 being located at the center of the support barrel 11 enables the turntable 13 to rotate intermittently without being affected. The support rod 3 passing through the turntable 13 enables it to support the electric push rod 31.

[0031] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed herein are intended to be covered by the claims of the present invention.
