Description

Technical Field

[0001] The utility model relates to the technical field of strip steel trimming, in particular to a trimming waste material collecting mechanism for a trimming disc shear. Background Art

[0002] The disc shear is only used for strip trimming in the cross-cutting unit, and can perform longitudinal continuous shearing of narrow and wide strips in the longitudinal shearing unit. It can be used for longitudinal shearing of raw materials for cold-rolled strips, and is also the main equipment for the cold-rolled strip longitudinal shearing and rewinding production line. When traditionally trimming the strip, the edge waste of the cold-rolled strip that falls off is in the form of long strips and has sharp edges, which will cause scratches to the staff, posing a safety hazard. At the same time, the edge waste generated extends from the edge of the cold-rolled strip to the ground, increasing the space occupied. After the processing is completed, the staff will handle it, which greatly increases the labor intensity of the staff.

[0003] To this end, the patent specification with publication number CN214978115U discloses a disc shearing edge device with waste collection, a waste winding device is provided on the front side of the disc shearing machine body, and a collection box is provided on the side of the waste winding device away from the disc shearing machine body. The device has a simple structure and is easy to operate and use. The waste winding device can collect and roll up the waste cut from the edge of the cold-rolled strip, avoiding scratches on the staff caused by dragging and placing it, greatly increasing the safety of use. The reciprocating mechanism can realize the uniform winding of the waste cut from the edge of the cold-rolled strip on the first and second winding discs, increasing the uniformity of winding. At the same time, the adjustment device can realize the adjustment between the first and second winding discs, so as to achieve the clamping effect on the end of the waste cut from the edge of the cold-rolled strip, and at the same time, the waste cut from the edge of the cold-rolled strip can be dropped after winding, increasing the convenience of use.

[0004] However, this waste collection mechanism for trimming disc shears has some shortcomings. First, the waste is easy to break due to the high speed of winding, and it cannot be continuously wound after breaking. Second, the debris generated during the trimming process cannot be processed in time. Therefore, it is necessary to optimize and improve its structure. Utility Model Content
