Abstract
Description
Technical Field
[0001] This utility model relates to the field of pad printing machine technology, specifically to a pad printing machine with a self-cleaning function. Background Technology
[0002] Pad printing machines are printing equipment suitable for printing on various materials such as plastics, toys, glass, metals, ceramics, electronics, and IC packaging.
[0003] During the printing process, the pad printing head continuously moves back and forth between the printing plate and the product surface to transfer ink. After repeated accumulation, some ink residue remains on the surface of the pad, which affects the printing clarity. Therefore, it is necessary to clean the pad printing head. Current pad printing head cleaning methods involve installing a movable adhesive tape on the front or side. After the pad printing machine completes the set number of prints, it prints once on the tape, automatically removing the residual ink. This method reduces the need for manual cleaning of the pad, but it still has the following drawbacks:
[0004] 1. Adhesive tape cannot be reused and needs to be replaced in a timely manner, which is costly;
[0005] 2. Adhesive tape has a certain stickiness, and it is easy for adhesive residue to remain on the tape head, affecting the clarity and accuracy of subsequent printing operations. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0030] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, a pad printing machine with a self-cleaning function includes a machine body 1. The machine body 1 includes a support platform and an L-shaped plate disposed above the support platform. The horizontal side of the L-shaped plate is located at the top, and a pad 2 is disposed below the horizontal side. The pad 2 is controlled by a control system. A groove 11 is disposed below the horizontal side of the L-shaped plate. Opposite lead screws 12 are disposed in the groove 11. One of the lead screws is controlled by a motor to rotate. A slider 13 is sleeved on the lead screw 12. The lower end of the slider 13 is connected to an electric telescopic rod 14. The pad 2 is installed below the electric telescopic rod 14. The motor controls the rotation of the lead screw, so that the slider 13 moves back and forth restricted by the two lead screws. The electric telescopic rod 14 controls the up and down movement of the pad 2. That is, the pad 2 can move back and forth and up and down.
[0031] The machine body 1 has a placement platform 3 on the front side, which can move up and down. The lower end of the placement platform 3 is provided with a lead screw 15. The front side of the machine body 1 is fixed with a vertical rod 16, and a support plate 17 is provided below. The placement platform 3 is sleeved on the outside of the vertical rod 16, and the lead screw 15 rotates through the support plate 17. By rotating the lead screw 15, the placement platform 3 can be moved up and down to adjust its height. It cooperates with the printing head 2 to place the item to be printed on the placement platform 3 for printing.
[0032] The placement table 3 is equipped with a cleaning mechanism 4 that cooperates with the pad printing head 2. The cleaning mechanism 4 includes a water tank 5 without a top cover. A motor 6 is located at the bottom of the water tank 5. The output end of the motor 6 extends into the water tank 5 and is connected to a rotating rod 7. Multiple scrapers 8 are evenly arranged along the circumference at the upper end of the rotating rod 7. The scrapers 8 are arc-shaped curved structures that cooperate with the pad printing head 2. The upper end of the scrapers 8 is a raised curved structure and is made of a plastic material with a certain degree of elasticity. When the pad printing head 2 is inserted into the scraper 8, the ink adhering to it is thoroughly cleaned by the rotation of the scraper 8, so that the cleaning is thorough.
[0033] The water tank 5 has a water pipe 18 inserted into one side. The inner wall of the water tank 5 has a water level line 25. The upper end of the water level line 25 is at the same height as the end of the water pipe 18 inside the water tank 5, so that the water level in the water tank 5 can be checked and the water pipe 18 can be prevented from being submerged. The side wall of the water pipe 18 is equipped with a water pump 19. The other side of the water tank 5 is equipped with a drain pipe 23. The drain pipe 23 is equipped with a valve 24. After opening the valve 24, the wastewater can be discharged.
[0034] A support frame 9 is slidably mounted on the top of the water tank 5. The front and rear side walls of the water tank 5 are provided with grooves 20. Both ends of the support frame 9 are inserted into the grooves 20. A screw 21 is provided between the left and right inner walls of one of the grooves 20. One end of the screw 21 extends out of the water tank 5 and is connected to a motor 22. After the motor 22 is started, the screw 21 rotates, controlling the left and right movement of the support frame 9. A detachable absorbent sponge 10 is provided inside the support frame 9. The top of the support frame 9 has a rectangular groove that mates with the rubber head 2. The longitudinal section of the absorbent sponge 10 in the left and right directions is an I-shaped structure and is inserted into the rectangular groove, so that the absorbent sponge 10 is just inserted into the rectangular groove, which is convenient for disassembly and can clean the rubber head 2.
[0035] The specific usage method is as follows: The printing head 2 is controlled by the control system to move back and forth and up and down, and cooperates with the items to be printed on the placement table 3 to achieve printing. After multiple printings, the printing head 2 is moved into the water tank 5, which contains clean water, so that the printing head 2 and the scraper 8 are in close contact. By starting the motor 6, the rotating rod 7 is rotated, and the scraper 8 scrapes off the ink on the printing head 2, making the cleaning thorough. After cleaning, the printing head 2 rises to the top of the water tank 5. After starting the motor 22, the screw 21 rotates, controlling the support frame 9 to move left and right. The support frame 9 contains a water-absorbing sponge 10, which moves to the underside of the printing head 2, pressing down the printing head 2 to absorb the water on the printing head, making it clean and thorough, and facilitating clearer subsequent printing operations.
