Technical Field

[0001] The present application relates to the technical field of copper strip processing, and in particular to a copper strip thickening shearing device. Background Art

[0002] Copper strip is a strip-shaped metal component, mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, connectors, and mainly used as conductive, heat-conductive, and corrosion-resistant equipment, such as electrical components, switches, washers, gaskets, vacuum devices, radiators, conductive base materials, and various parts such as automobile water tanks, heat sinks, and cylinder plates.

[0003] During the production process of copper strips, the edges of the copper strips will be uneven, so the waste edges need to be sheared and then reeled to ensure the quality of the copper strips. However, the copper strips have a certain hardness. Improper winding during the reeling process can easily cause the waste edges to hit the good copper strips, thereby destroying the surface quality of the good copper strips and reducing the quality of the copper strips. Summary of the invention

[0004] In order to improve the quality of copper strip, the present application provides a copper strip thickening shearing device.

[0005] The present application provides a copper strip thickening shearing device, which adopts the following technical solution: A copper strip thick shearing device comprises a frame, a conveying roller for conveying the copper strip, and a cutting mechanism for shearing the copper strip to form waste edges, wherein a crushing mechanism is arranged on the frame, and the crushing mechanism comprises: Two crushing rollers are rotatably mounted on the frame and are used to crush the waste edges into chips; Two guide rollers are rotatably mounted on the frame and are used to guide the waste edges to the two crushing rollers for crushing; A driving assembly, used for driving the multiple crushing rollers to rotate; The collecting component is used for collecting the debris.

[0006] By adopting the above technical scheme, the conveying roller starts to drive the copper strip to be conveyed, and the cutting mechanism starts to shear the copper strip to form waste edges. The waste edges are guided and conveyed to two crushing rollers through two guide rollers. The driving component drives the two crushing rollers to rotate to crush the waste edges to form debris. The debris falls into the collecting component for collection, thereby reducing the probability of the waste edges hitting the good copper strip and improving the quality of the copper strip.

[0007] Moreover, the scrap edges have a certain hardness, so it is extremely troublesome to roll them up and it will take up a large space. Therefore, compared with rolling up the scrap edges for collection, crushing and collecting can greatly reduce the space occupied by the scrap edges, thereby improving the collection effect of the scrap edges. Moreover, the scrap edges of the copper strip need to be crushed before recycling, so while improving the collection effect, it does not increase energy consumption, thereby greatly improving the recycling efficiency of the scrap edges of the copper strip.

[0008] Optionally, the driving component includes: Two main gears are respectively arranged on the two crushing rollers and mesh with each other; A driving member is arranged on the frame; The secondary gear is arranged on the driving member and rotates under the action of the driving member and meshes with one of the main gears.

[0013] By adopting the above technical solution, the width of the waste edge is narrow, while the length of the crushing roller is long and much larger than the width of the waste edge. When the waste edge is crushed by the two crushing rollers, it is continuously concentrated in one place, which makes the crushing roller easy to be damaged, thereby greatly reducing the crushing effect of the waste edge. As a result, the crushing effect of the waste edge is deteriorated, thereby increasing the probability of the waste edge hitting the good copper strip and reducing the quality of the copper strip.

[0014] The swing assembly is started to push the sliding seat to move back and forth, and the reciprocating movement of the sliding seat drives the two guide rollers to move back and forth.

[0038] A copper strip can produce at most two scrap edges, so the scrap edges cut off by copper strips transported from multiple units or multiple locations can be guided to the guide roller 42 for transport, so that the two crushing rollers 41 can crush more scrap edges, thereby improving the crushing efficiency. At the same time, the swing assembly 7 drives the two sliding seats 12 to move back and forth, so that the two guide rollers 42 move back and forth, so that the scrap edges move back and forth along the axis of the crushing roller 41, so that the scrap edges can change the contact position with the crushing roller 41, reducing the probability of the crushing roller 41 being damaged by the crushing point of the crushing roller 41 concentrating on one place, thereby improving the crushing effect of the scrap edges.
