A large number of plastic electroplating products have been used in industries such as electronics, automobiles, and household goods.
[0003] Before plastic electroplating, the plastic needs to be cleaned to remove dirt and fingerprints left in the plastic molding process. It can be cleaned with an alkaline agent and then neutralized with acid immersion and washed with water. When cleaning existing plastics, a larger container is used to hold the solution, and then the plastic to be cleaned is directly immersed in the solution. The plastic surface is cleaned by contact between the solution and the plastic surface. Since the solution and the plastic are relatively static, the decontamination efficiency is low. When the plastic is immersed in the solution, the plastics overlap, resulting in poor cleaning effect of the overlapping parts. A solution is proposed below to address the above problems.

The support member 14 can prevent the plastic from rubbing against the partition 4 when moving, and convert the sliding friction into rolling friction with the ball 17 to avoid damage to the plastic. At the same time, the spring 16 can control the distance that the ball 17 extends out of the outer frame 15, so as to be suitable for plastics of different thicknesses.
[0030] See also Figure 5 The cleaning tank 5 is symmetrically provided with inclined plates inside, and a drainage pipe 18 for drainage is provided at the bottom of the cleaning tank 5. The drainage pipe 18 is located between the two inclined plates, and the inclined plates can facilitate the movement of the solution inside the cleaning tank 5 toward the drainage pipe 18, so as to facilitate discharge and avoid aggregation. A valve 19 for controlling the opening and closing of the drainage pipe 18 is installed on the drainage pipe 18. The drainage pipe 18 is opened and closed by the valve 19, and the design of multiple drainage pipes 18 allows each cleaning tank 5 to be used separately. The bottom thread of the drainage pipe 18 is matched with a receiving pipe 20, and a filter screen 21 for receiving impurities is installed at the bottom of the receiving pipe 20.

[0031] See also Figure 5 and Figure 6 A support plate 6 for supporting the plastic is provided inside the cleaning tank 5. The support plate 6 and the cleaning tank 5 slide up and down in cooperation.

The cleaning tank 5 is symmetrically provided with stabilizing rods 22, which pass through the corresponding support plates 6. The stabilizing rods 22 and the support plates 6 slide in cooperation. The design of the stabilizing rods 22 can limit the support plates 6 so that the stabilizing rods 22 are always in a horizontal device when moving up and down, thereby ensuring the stability of the movement. An eccentric wheel 7 for pushing the support plate 6 to move up and down is rotatably provided inside each cleaning tank 5. The movement of the support plate 6 is driven by the rotation of the eccentric wheel 7. The support plate 6 will push the solution on the one hand and move the plastic on the other hand, thereby improving the cleaning effect of the solution on the plastic.
[0032] See also Figure 2A driving device 8 for driving all eccentric wheels 7 to rotate simultaneously is provided on one side of the container 1. The driving device 8 includes a motor 9 and a driving shaft 10. The motor 9 is arranged on one side of the container 1. The driving shaft 10 passes through all the cleaning slots 5 in sequence. The driving shaft 10 and the cleaning slots 5 rotate in cooperation. The driving shaft 10 passes through all the eccentric wheels 7 in sequence. The eccentric wheels 7 and the driving shaft 10 are fixedly connected. All the eccentric wheels 7 can be synchronously driven by the driving shaft 10. The eccentric wheels 7 are arranged at an angle of 90 degrees in the same direction. The eccentric wheels 7 are located at the bottom of the support plate 6 and are in contact with the support plate 6. The adjacent eccentric wheels 7 are at an angle of 90 degrees, which can balance the force. , so that each rotation will push multiple support plates 6 into sequential pushes, avoiding the large power required to push multiple support plates 6 at the same time, reducing the power of the motor 9, and extending the service life of the motor 9 and the drive shaft 10. One end of the drive shaft 10 is connected to the output shaft of the motor 9, and one end of the drive shaft 10 is connected to a driven wheel 11. The output end of the motor 9 is connected to a driving wheel 12. The driving wheel 12 and the driven wheel 11 are covered with a transmission belt 13 on their outer sleeves. The diameter of the driving wheel 12 is smaller than the diameter of the transmission wheel. The diameter of the driving wheel 12 is smaller than the diameter of the driven wheel 11, which can ensure that the speed of the motor 9 is reduced, thereby increasing the power and ensuring the stability of the rotation.
[0033] Working principle:
[0034] When in use, each individual plastic is placed inside each cleaning tank 5, and the plastic will be located between the support members 14 on both sides of the cleaning tank 5. The plastic will squeeze the ball 17 to move inside the outer frame 15, thereby squeezing the spring 16. The elastic force of the spring 16 will support the plastic, and the pneumatic motor 9 will drive the driving wheel 12 to rotate. The driving wheel 12 will drive the driven wheel 11 to rotate through the transmission belt 13, thereby driving the drive shaft 10 to rotate through the driven wheel 11. When the driving wheel rotates, it will drive the cam to rotate, and the cam will push the support plate 6 to move upward. When the cam passes the highest point, the support plate 6 will move downward under the action of its own gravity. The support plate 6 will drive the solution inside the cleaning tank 5 to shake, and at the same time drive the plastic to move, thereby increasing the impact of the solution on the plastic, thereby improving the cleaning performance.
[0035] When the plastic moves up and down, rolling friction occurs between the plastic and the rolling ball 17. The addition of the rolling ball 17 converts the sliding friction between the plastic and the cleaning tank 5 into rolling friction, which can reduce the wear of the plastic and ensure the quality of the plastic.
[0036] After cleaning, the plastic is taken out from the cleaning tank 5, and the valve 19 is opened. The solution in the cleaning tank 5 flows out through the drain pipe 18 under the action of its own gravity, and enters the receiving tube 20 after passing through the distribution pipe, and finally passes through the filter 21. The filter 21 allows the solution to pass through, but separates the impurities in the solution to facilitate subsequent treatment of the solution. The threaded combination of the receiving tube 20 and the distribution pipe can facilitate the removal of the receiving tube 20, thereby facilitating the cleaning of the impurities inside the receiving tube 20.
