Description

Technical Field

[0001] This utility model relates to the technical field of electroplating operations, and in particular to a roller for preventing material jamming. Background Technology

[0002] Barrel plating is a high-volume electroplating process suitable for small parts. It involves placing the parts in a rotating drum, causing them to tumble in an electroplating solution, thus achieving a uniform electroplating layer deposition. Currently, commercially available barrels all require a cover plate to seal the opening. For example, Chinese patent CN201420287344.0 discloses a diode electroplating barrel, which includes a barrel body and a cover plate, both of which have several electroplating solution inlet holes. When using this barrel, the cover plate must be opened first, the parts placed in, and then the cover plate closed. Over time, the continuous friction between the cover plate and the barrel body creates gaps. During barrel plating of small parts, parts may become stuck in these gaps, leading to incomplete electroplating and increasing the need for subsequent defective product sorting. Summary of the Invention

[0003] In view of this, the present invention provides an anti-jamming roller to solve the above problems.

[0004] An anti-jamming roller includes two opposing wall panels and a cylinder disposed between the two wall panels. The cylinder includes four long wall panels connected in pairs, a short wall panel disposed on one side of the last long wall panel, an inner wall panel disposed on the side of the short wall panel away from the long wall panels, and an outer wall panel disposed on one side of the first long wall panel. The angle between the inner wall panel and the short wall panel is greater than the angle between the short wall panel and the long wall panels connected to it, and the length of the inner wall panel is the same as the length of the short wall panel. The angle between the outer wall panel and the long wall panels connected to it is greater than the angle between two adjacent long wall panels, and the length of the outer wall panel is the same as the length of the long wall panels. The inner wall panel is located inside the outer wall panel, and an opening exists between the inner wall panel and the outer wall panel.

[0005] Furthermore, the outer circumferential wall of the wall panel is toothed.

[0006] Furthermore, a circular hole is provided at the center of the wall panel.

[0007] Furthermore, the cross-section of the cylinder along the direction perpendicular to the arrangement of the two wall panels is generally hexagonal, octagonal, or circular.

[0008] Furthermore, the included angle between the two connected long wall panels is 120°.

[0009] Furthermore, the angle between the short wall plate and the long wall plate connected to it is 120°, and the length of the short wall plate is two-thirds of the length of the long wall plate.

[0010] Furthermore, the included angle between the inner wall plate and the short wall plate is 125°-130°.

[0011] Furthermore, the included angle between the outer wall panel and the long wall panel connected thereto is 125°-130°.

[0012] Compared with existing technologies, the anti-jamming roller provided by this utility model is located inside the outer wall plate via the inner wall plate, and there is no need to use a cover plate to close the opening. During the barrel plating operation, the cylinder rotates counterclockwise, and the screws will fall from the inner wall plate onto the outer wall plate without falling out of the opening. This avoids the gaps created when closing the opening with a cover plate that could trap the screws, preventing incomplete zinc plating of the screws and improving the efficiency of the barrel plating operation. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the anti-jamming roller provided by this utility model.

[0014] Figure 2 for Figure 1 A schematic diagram of the cross-section of the anti-jamming roller. Detailed Implementation

[0015] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0016] like Figure 1 The diagram shows the structure of the anti-jamming roller provided by this utility model. The anti-jamming roller includes two opposing wall plates 10 and a cylinder 20 disposed between the two wall plates 10. It is conceivable that the anti-jamming roller also includes some other functional modules, such as a drive rotation module, an electroplating module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0017] It should be noted that the anti-jamming roller is made entirely of PP material and is used for barrel plating of small parts such as screws. The roller has drive modules on both sides that enable it to rotate. During barrel plating, the anti-jamming roller is placed horizontally, meaning its axis is parallel to the horizontal direction.

[0018] The outer circumferential wall of the wall panel 10 is toothed, so that the two wall panels 10 are toothed with the drive rotation module to transmit the power required for the roller to rotate.

[0019] A circular hole 11 is provided in the center of the wall panel 10, so that the two cables of the cathode and anode pass through the two circular holes 11 respectively to discharge into the inside of the anti-jamming roller, thereby completing the electroplating operation.

[0020] Please see Figure 2 The cross-section of the cylinder 20 along the direction perpendicular to the arrangement of the two wall panels 10 is hexagonal, octagonal, or circular, with hexagonal being the most preferred. This allows the screws to fall more widely when turned over, resulting in more thorough mixing of the screws and significantly improving the stability of the screw plating thickness.

[0021] The cylinder 20 includes four long wall plates 21 connected in pairs, a short wall plate 22 disposed on one side of the last long wall plate 21, an inner wall plate 23 disposed on the side of the short wall plate 22 away from the long wall plate 21, and an outer wall plate 24 disposed on one side of the first long wall plate 21.

[0022] The four long wall panels 21 are arranged in a hexagonal pattern, with each of the four sides of the hexagon connected in pairs, and the included angle between two adjacent long wall panels 21 is 120°.

[0023] The included angle between the short wall plate 22 and the long wall plate 21 connected thereto is 120°, and the length of the short wall plate 22 is two-thirds of the length of the long wall plate 21.

[0024] The angle between the inner wall panel 23 and the short wall panel 22 is greater than the angle between the short wall panel 22 and the long wall panel 21 connected to it. Specifically, the angle between the inner wall panel 23 and the short wall panel 22 is 125°-130°, preferably 128°. The length of the inner wall panel 23 is the same as the length of the short wall panel 22.

[0025] The angle between the outer wall panel 24 and the long wall panel 21 connected to it is greater than the angle between two adjacent long wall panels 21. Specifically, the angle between the outer wall panel 24 and the long wall panel 21 connected to it is 125°-130°, preferably 128°. The length of the outer wall panel 24 is the same as the length of the long wall panel 21. Since the length of the short wall panel 22 is two-thirds of the length of the long wall panel 21, the inner wall panel 23 connected to the short wall panel 22 is located inside the outer wall panel 24, thereby creating an opening 25 between the inner wall panel 23 and the outer wall panel 24. During the counter-clockwise barrel plating operation, the screws are guided to fall from the inner wall plate 23 onto the long wall plate 24. As the rotation continues, they fall onto the long wall plate 21 connected to the long wall plate 24, without falling out of the opening 25. Therefore, the opening 25 does not need to be sealed with a cover plate, thus avoiding the gaps caused by friction between the barrel and the cover plate during long-term use of traditional barrels, which can trap small parts such as screws and prevent incomplete electroplating of the parts.

[0026] During the barrel plating operation, the cylinder 20 is made to conform to... Figure 2 As the screw rotates counterclockwise, it continuously rolls inside the cylinder 20. When it passes through the opening 25, the screw falls from the inner wall plate 23 onto the outer wall plate 24 and does not fall out of the opening 25. This avoids the screw getting stuck in the gap when the opening is closed by the cover plate, prevents the screw from being incompletely galvanized, and improves the efficiency of barrel plating.

[0027] When it is necessary to remove the screws after the barrel plating operation is completed, simply make the cylinder 20 conform to... Figure 2 Rotating clockwise for one full rotation will cause the screw to fall out of the cylinder 20 through the opening 25 from the outer wall plate 24, thus completing the unloading operation.

[0028] Compared with the prior art, the anti-jamming roller provided by this utility model forms the opening 25 through the inner and outer wall plates 23 and 24, and there is no need to use a cover plate to close the opening 25. During the barrel plating operation, the cylinder 20 rotates counterclockwise, and the screws will fall from the inner wall plate 23 onto the outer wall plate 24, and will not fall out of the opening 25. This avoids the gaps created when closing the opening with a cover plate that can trap the screws, prevents incomplete zinc plating of the screws, and improves the efficiency of barrel plating.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
