[0002] With the continuous development of society and the continuous advancement of science and technology, the technology related to plastic product processing is also constantly improving. At present, in the processing of plastic sheets, electroplating equipment is often used to assist in the electroplating of plastic sheet products, which can enhance the corrosion resistance and wear resistance of plastic sheets and make them more beautiful.

When the device metal-plates a large number of plastic products, it is necessary to repeatedly rotate the threaded rod many times to clamp the plastic products between the fixed plate and the electrode connecting plate. The threaded rod and the fixed plate are prone to slippage after long-term use, resulting in the inability to normally clamp and metal-plate the plastic products subsequently, which is not conducive to the use of the device. A device for metal-plating the surface of plastic products is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The plastic product is clamped between the clamping block and the electrode connecting plate. The mass of the gravity block is large enough to prevent the horizontal plate and the plug shaft from moving upward. The plug shaft and the horizontal plate cannot move along the clamping block, thereby preventing the rectangular block and the clamping block from moving.

Then, the rectangular rod and the inner wall of one side of the groove are clamped to prevent the rotating rod and the rotating block from rotating at will, so as to improve the stability of the connection between the clamping block and the limit groove. When the clamping block or the electrode connecting plate is damaged, it is convenient to replace it in time so that the subsequent device can work normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1-6 A device for plating metal on the surface of plastic products, comprising a workbench 1, a washing tank, an inkjet tank, a copper plating tank 3, a chrome plating tank, a moving block 4, a hydraulic lift cylinder 2, and two graphite cartridges 9. The driving end of the hydraulic lift cylinder 2 is fixedly connected to a fixed rod 10, and a fixed sleeve 12 with an inverted T-shaped cross section is provided at the lower end of the fixed rod 10. A fixed plate 15 and an electrode connecting plate 17 are fixedly connected to the lower surface of the fixed sleeve 12. The cross section of the fixed plate 15 is L-shaped, and a cross-section is slidably connected to the fixed plate 15. The clamping block 16 is set with a T-shaped cross-section, and a rectangular block 14 is fixedly connected to the clamping block 16. A mounting groove 25 is provided on the rectangular block 14, and a limit assembly is provided in the mounting groove 25. The limit assembly includes a cross plate 13 and an insertion shaft 26. The cross plate 13 is slidably set in the mounting groove 25. An opening for the cross plate 13 to move up and down is provided on one side of the mounting groove 25. The insertion shaft 26 is fixedly connected to the lower surface of the cross plate 13. A plurality of equally spaced card slots are provided on the fixed plate 15, and the insertion shaft 26 is clamped into the card slots.

[0030] A gravity block 30 is rotatably provided in the mounting groove 25, and the surface of the gravity block 30 fits the surface of the cross plate 13, and the lower inner wall of the mounting groove 25 is fixedly connected to the first spring 24, and one end of the first spring 24 away from the inner wall of the mounting groove 25 is fixedly connected to the lower surface of the cross plate 13. During the rotation of the gravity block 30, the surface of the gravity block 30 will move downward together with the upper surface of the cross plate 13, and the first spring 24 will deform at the same time. The inner wall of one side of the mounting groove 25 is rotatably connected to the rotating shaft 23, and the gravity block 30 is fixedly connected to the rotating shaft 23. The cross section of the rotating shaft 23 is T-shaped, and the rotating shaft 23 is provided with anti-slip grooves, so that the rotating shaft 23 rotates in the mounting groove 25, and the gravity block 30 will rotate at the same time. The anti-slip grooves can increase the friction when in contact with the rotating shaft 23, and the rotation of the gravity block 30 is more conveniently controlled by the rotating shaft 23.

[0031] One side surface of the mounting groove 25 is rotatably connected to a limit plate 28 for supporting the gravity block 30, and a torsion spring 29 is fixedly connected to the limit plate 28, and one end of the torsion spring 29 is fixedly connected to the side inner wall of the mounting groove 25. In the initial state, the gravity block 30 is tilted, and the gravity block 30 contacts the upper surface of the limit plate 28. Under the elastic force of the torsion spring 29, the gravity block 30 can be prevented from flipping downward under the action of gravity. Grooves 27 are provided on both side surfaces of the fixing sleeve 12, and a rotating rod 18 is rotatably connected in each groove 27. A rectangular through hole is provided on the rotating rod 18, and a rectangular rod 11 is slidably connected in the rectangular through hole. The cross section of the rectangular rod 11 is T-shaped, and one end of the rectangular rod 11 is engaged with the inner wall of the groove 27.

[0032] Each rotating rod 18 is fixedly connected to a rotating block 19, and a clamping block 20 is fixedly connected to one side of the rotating block 19. A limiting groove for connecting the clamping block 20 is provided on the fixed rod 10, and a rubber pad 21 is fixedly connected to the outer surface of the clamping block 20. The lower end of the fixed rod 10 is extended into the fixed sleeve 12. At this time, the two rotating blocks 19 are located on both sides of the fixed rod 10. Then, the two rotating rods 18 are rotated in sequence. When the rotating rod 18 rotates in the direction close to the fixed rod 10, the clamping block 20 at one end of the rotating block 19 will be connected to the limiting groove, and the rubber pad 21 on the outside of the clamping block 20 will be in close contact with the inner wall of the limiting groove, which is conducive to improving the tightness when the clamping block 20 and the limiting groove are connected.

[0033] A support plate 22 is fixedly connected to each groove 27, and the rotating rod 18 is rotatably set on the support plate 22. The support plate 22 has a certain supporting effect on the rotating rod 18, so as to improve the stability of the rotating rod 18 when rotating. A nozzle is fixedly connected to each graphite cartridge 9, and a nozzle 8 is provided on one side of the nozzle. A threaded sleeve 7 is fixedly connected to the nozzle 8, and the threaded sleeve 7 is threadedly connected to the nozzle. By threading the threaded sleeve 7 and the nozzle, the nozzle 8 and the nozzle can be firmly connected together. Similarly, when the nozzle 8 is damaged due to long-term use, it is convenient to replace the nozzle 8 in time.

[0034] A screw rod 6 is rotatably provided on the workbench 1, and a limit slide 5 and a servo motor are fixedly installed on the workbench 1. The driving end of the servo motor is fixedly connected to one end of the screw rod 6, the moving block 4 is threadedly connected to the screw rod 6, and the moving block 4 is slidably connected to the limit slide 5. Under the driving action of the servo motor, the screw rod 6 and the workbench 1 rotate relative to each other, and the moving block 4 moves along the screw rod 6. At the same time, the moving block 4 slides relative to the limit slide 5. The limit slide 5 can limit the moving trajectory of the moving block 4 to prevent the moving block 4 from rotating.

[0035] In the present invention, when in use, first place the plastic product (not shown) between the fixed plate 15 and the electrode connecting plate 17, then push the clamping block 16. During the relative sliding of the clamping block 16 and the fixed plate 15, one side surface of the clamping block 16 will fit with the surface of the plastic product. Then continue to push the clamping block 16 until the plastic product is clamped between the clamping block 16 and the electrode connecting plate 17. The two side surfaces of the plastic product are respectively tightly attached to the surfaces of the clamping block 16 and the electrode connecting plate 17. In the initial state, the gravity block 30 is tilted, and the gravity block 30 contacts the upper surface of the limit plate 28. Under the elastic force of the torsion spring 29, the gravity block 30 can be prevented from flipping downward under the action of gravity.

[0036] Then, the position of the clamping block 16 is kept unchanged, and the rotating shaft 23 is manually rotated in the mounting groove 25. After the gravity block 30 rotates together, one end surface of the gravity block 30 contacts the upper surface of the horizontal plate 13. As the gravity block 30 continues to rotate, the gravity block 30 moves downward against the upper surface of the horizontal plate 13, and the first spring 24 is deformed at the same time. When the gravity block 30 is set vertically (as shown in the attached figure), the first spring 24 is deformed. Figure 6 As shown), at this time, the lower end of the plug shaft 26 will extend into the corresponding card slot, and the mass of the gravity block 30 is large enough to prevent the horizontal plate 13 and the plug shaft 26 from moving up, and the plug shaft 26 and the horizontal plate 13 cannot move along the clamping block 16, thereby preventing the rectangular block 14 and the clamping block 16 from moving, so that the clamping block 16 and the electrode connecting plate 17 can stably clamp the plastic product, which can effectively avoid the phenomenon of thread slippage, so that after a long period of use, the device can also normally clamp and metal-plate the plastic product, which is beneficial to the use of the device.

[0037] When the lever 10 is moved in a direction close to the fixed rod 10 , the block 20 at one end of the lever 19 will be connected with the limit groove, and the rubber pad 21 on the outside of the block 20 will be in close contact with the inner wall of the limit groove, which is conducive to improving the tightness of the connection between the block 20 and the limit groove. Then, the rectangular rod 11 is pushed, and during the relative sliding of the rectangular rod 11 and the lever 18 , one end of the rectangular rod 11 will be engaged with the inner wall of one side of the groove 27, thereby preventing the lever 18 and the lever 19 from rotating at will, so as to improve the stability of the connection between the block 20 and the limit groove. When the clamping block 16 or the electrode connecting plate 17 is damaged, it is convenient to replace it in time so that the subsequent device can work normally.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
