DETAILED DESCRIPTION

[0019] In the following, the application will be further described in conjunction with the drawings and the specific embodiments, it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.

[0020] As Figures 1-3 shown, the high-strength electroplating drum screen plate, including the bottom plate 1 in the form of mesh, a plurality of bottom plate 1 can be spliced into a drum, the top of the bottom plate 1 is provided with the clamping strip 2, the clamping strip 2 is connected end to end into a rectangle, the top of the clamping strip 2 is provided with the sliding groove 21, the sliding groove 21 is provided with the first spring 22 and the frame 3, one end of the frame 3 is connected with the first spring 22, the other end of the frame 3 extends above the sliding groove 21, the inner side of the frame 3 is provided with the baffle 4 in the form of mesh, the baffle 4 is close to the workpiece to be electroplated, the inner side of the baffle 4 is provided with the cross beam 41 and the longitudinal beam 42 which are staggered with each other; a plurality of nozzles 5 are arranged between the bottom plate 1 and the baffle 4, the nozzles 5 are used for spraying the electroplating liquid outside the bottom plate 1 towards the inner side of the baffle 4.

[0021] In the process of drum rolling, the workpiece will collide and extrude with the baffle 4, the baffle 4 will displace after being impacted, thereby driving the frame 3 to slide towards the inner side of the sliding groove 21 and compressing the first spring 22, realizing the buffering effect and preventing the baffle 4 from being damaged, while the bottom plate 1 and the baffle 4 are separated from each other, after the baffle 4 is accidentally damaged, the bottom plate 1 can play a role in resisting the workpiece, ensuring that the workpiece can reliably roll in the drum and complete the electroplating operation. Through the arrangement of the cross beam 41 and the longitudinal beam 42, the strength of the baffle 4 is significantly improved, further, through the arrangement of the nozzle 5, the flow efficiency of the electroplating liquid is improved, thereby ensuring that the external electroplating liquid can quickly enter the inner side of the drum, improving the electroplating efficiency.

[0022] When the first spring 22 is in a completely compressed state, the baffle 4 is attached to the clamping strip 2, so that the clamping strip 2 plays a limiting role on the baffle 4, ensuring that the baffle 4 and the bottom plate 1 are in a state of mutual separation, thereby providing sufficient buffering space.

[0023] The longitudinal beam 42 intersects the cross beam 41 and connects the cross beams 41, the top of the longitudinal beam 42 is provided with a groove 421, one end of the nozzle 5 is located outside the bottom plate 1, and the other end of the nozzle 5 is close to the baffle 4; the side of the baffle 4 facing the bottom plate 1 is provided with a sleeve 43, the bottom of the sleeve 43 is arranged on the baffle 4 and below the groove 421, the bottom of the sleeve 43 is provided with a water outlet hole 430, the water outlet hole 430 is communicated with the groove 421, the other end of the nozzle 5 is inserted into the sleeve 43 and can slide in the sleeve 43, and the nozzle 5 sprays water to the inside of the baffle 4 through the water outlet hole 430. There is no overlapping part between the cross beam 41 and the longitudinal beam 42, which can reliably improve the strength of the baffle 4 and improve the flatness of the appearance. Further, the electroplating liquid sprayed by the nozzle 5 first enters the sleeve 43 and then is discharged into the groove 421 through the water outlet hole 430, so that the pressure of the electroplating liquid in the sleeve 43 can be adjusted by adjusting the flow of the nozzle 5, that is, when the flow of the nozzle 5 is greater than the discharge flow of the water outlet hole 430, the electroplating liquid will lift the sleeve 43, so that the baffle 4 is away from the bottom plate 1, thereby reducing the impact force of the workpiece on the baffle 4 and improving the buffering effect.

[0024] The groove 421 is provided with a movable plate 422 and a second spring 423, one end of the second spring 423 is connected with the groove bottom of the groove 421, the other end of the second spring 423 is connected with the movable plate 422, the outer diameter of the movable plate 422 gradually decreases from top to bottom, the minimum outer diameter of the movable plate 422 is smaller than the inner diameter of the groove 421, and the maximum outer diameter of the movable plate 422 is greater than the inner diameter of the groove 421. When the second spring 423 is in a natural elongation state, there is a gap between the outer wall of the movable plate 422 and the inner wall of the groove 421, at this time, the pressure of the electroplating liquid in the sleeve 43 is small, and the electroplating liquid can flow into the groove 421 through the water outlet hole 430 and be discharged to the inside of the baffle 4 through the groove 421. When the movable plate 422 moves towards the inside of the groove 421 under the impact force of the workpiece, the movable plate 422 will block the groove 421, so that the electroplating liquid sprayed by the nozzle 5 cannot be discharged outward through the water outlet hole 430, at this time, the pressure in the sleeve 43 will rapidly increase to provide a supporting force for the reset of the baffle 4.

[0025] The outer side of the bottom plate 1 is provided with a water pump 50, and the output end of the water pump 50 is communicated with the nozzle 5. The power of the water pump 50 can be remotely controlled by the controller, so that the flow of the electroplating liquid sprayed by the nozzle 5 can be reliably controlled.

[0026] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
