[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0014] like Figures 1-5 As shown, an antistatic screen printing machine includes a base 1, a support frame 2 is fixedly installed on one side of the upper surface of the base 1, and a screen mold 4 is rotatably installed between the two sides of the inner wall of the support frame 2 through a positioning rod 3. A scraping component 5 for scraping ink on the screen is provided on one side of the upper surface of the screen mold 4. A support platform 6 is fixedly installed on the upper surface of the base 1 near the support frame 2; The screen mold 4 has movable plates 7 on both sides of its surface. Two support plates 8 are movably arranged between the two movable plates 7. Mounting brackets 9 are fixedly installed on opposite sides of the two support plates 8. Static rods 11 are rotatably installed between the inner walls of the two mounting brackets 9 via rotating rods 10. Electric slip rings 19 are installed on one side of the inner wall of each of the two mounting brackets 9, and the power supply terminals of the two electric slip rings 19 are electrically connected to the corresponding electrostatic bars 11.

[0015] After placing the workpiece on the upper surface of the support platform 6, the operator rotates the screen printing mold 4 to make it fit the workpiece on the support platform 6. Then, the operator activates the scraping component 5 to scrape the surface of the screen printing mold 4, so that the pattern is screen-printed onto the workpiece surface. Before applying ink to the surface of the screen printing mold 4, the operator rotates the screen printing mold 4 and then manually pushes the mounting bracket 9 to move the electrostatic bar 11 along the surface of the screen printing mold 4. This allows the electrostatic bar 11 to eliminate static electricity on both sides of the screen printing mold 4, avoiding quality problems such as pitting and pinholes caused by static electricity.

[0016] The rotor of the slip ring 19 is connected to the wire of the electrostatic bar 11 and rotates with it. The stator of the slip ring 19 is connected to an external flexible power line and kept fixed. By using a flexible power line, the power line is prevented from being pulled and broken when the slip ring 19 moves, so as to achieve continuous and stable power supply to the electrostatic bar 11 during rotation. The electrostatic bar 11 is connected to an external high-voltage power supply through the slip ring 19. After the power supply is started, the discharge electrode of the electrostatic bar 11 generates a large number of positive and negative ions. These ions are guided to the surface of the wire mesh mold 4 under the action of electric field force and airflow, and neutralize the static charge, thereby eliminating static electricity.

[0017] In another embodiment of the present invention, grooves 12 are provided on both sides of the screen mold 4, and sliders 13 are slidably arranged in both grooves 12. The two sliders 13 are respectively fixedly connected to the corresponding moving plate 7 on the side away from each other. Two slide bars 14 are fixedly installed between the two sides of the inner wall of the two slide grooves 12. Two sliders 13 are slidably disposed on one side of the corresponding slide bar 14. A first spring 1401 is sleeved on both sides of the slide bar 14.

[0018] The slider 13 is adapted to the shape of the slide groove 12 to prevent the slider 13 from twisting when the slide groove 12 moves, so that the moving plate 7 can move stably along the direction of the slide groove 12. With the first spring 1401, under the elastic force of the first spring 1401, the electrostatic rod 11 will not move due to external force when the screen printing work is in progress, and it can automatically move back to its original position after the operator releases the electrostatic rod 11, which increases stability and practicality.

[0019] In another embodiment of the present invention, two moving grooves 15 are provided on the opposite side surfaces of the two moving plates 7, and a moving block 16 is slidably disposed in each moving groove 15. The two support plates 8 are respectively fixedly installed between the opposite moving blocks 16.

[0020] Each movable groove 15 has a movable rod 17 fixedly installed between the two sides of its inner wall. Each movable block 16 is slidably disposed on one side of the corresponding movable rod 17. A second spring 18 is sleeved on the other side of each movable rod 17.

[0021] By setting a second spring 18, it can push the moving block 16 inside the moving groove 15, so that the electrostatic bar 11 can move synchronously along the moving groove 15 while moving along the slide groove 12. This allows the electrostatic bar 11 to move closely against the wire mesh of the wire mesh mold 4, enhancing the effect of static elimination. Then, when the electrostatic bar 11 returns to its original position, the operator can push the electrostatic bar 11 to prevent it from getting stuck.

[0022] The first spring 1401 and the second spring 18 are made of 65Mn spring steel, providing stable elastic force.

[0023] In another embodiment of the present invention, the scraping assembly 5 includes a vertical plate 501, which is fixedly installed on one side of the upper surface of the screen mold 4. A cylinder 502 is fixedly installed on one side of the vertical plate 501, and the output end of the cylinder 502 passes through the vertical plate 501 and is fixedly installed with a scraper blade 503.

[0024] The staff activated cylinder 502, enabling the doctor blade 503 to scrape the ink off the surface of the screen mold 4.

[0025] The working principle of this antistatic screen printing machine: In use, after placing the workpiece on the upper surface of the support platform 6, the operator rotates the screen printing mold 4 to bring it into contact with the workpiece on the support platform 6. Then, the operator activates the scraping component 5 to scrape the surface of the screen printing mold 4, transferring the pattern onto the workpiece surface. Before applying ink to the surface of the screen printing mold 4, the operator rotates the mold 4 and then manually pushes the mounting bracket 9, causing the electrostatic bar 11 to move along the surface of the screen printing mold 4. This allows the electrostatic bar 11 to eliminate static electricity on both sides of the screen printing mold 4, preventing defects such as pitting and pinholes caused by static electricity. To address the issue of power supply, the rotor of the slip ring 19 is connected to the wires of the electrostatic bar 11 and rotates with it. The stator of the slip ring 19 is connected to an external flexible power supply line and remains fixed. By using a flexible power supply line, the situation of the power supply line being pulled and broken when the slip ring 19 moves is avoided, thus achieving continuous and stable power supply to the electrostatic bar 11 during rotation. The electrostatic bar 11 is connected to an external high-voltage power supply through the slip ring 19. After the power supply is started, the discharge electrode of the electrostatic bar 11 generates a large number of positive and negative ions. These ions are guided to the surface of the wire mesh mold 4 under the action of electric field force and airflow, and neutralize the static charge, thereby eliminating static electricity.

[0026] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
