Scrap chopper device of tension leveling machine

Abstract

The invention discloses a scrap chopper device of a tension leveling machine. The scrap chopper device comprises a movable cutter mounting seat mounted on a base and a roller cutter mounted on the movable cutter mounting seat. A static blade horizontally disposed on the base is disposed on one side of the roller cutter. A pair of movable blades which are in 180-degree symmetrical distribution is fixedly mounted on the roller cutter. The two movable blades can synchronously rotate along with the roller cutter and perform cutting motions. The two movable blades are arranged along a spiral direction, so that the cutting edges of the two movable blades are spiral lines. The two movable blades can move along the trajectory of the spiral lines to contact with the static blade so as to perform aluminum foil cutting. By the structure, the scrap chopper has the advantages that shearing force is reduced, shearing power is correspondingly reduced as compared with an original single-roller scrap chopper, the scrap chopper is low in noise, the cutting edges of the scrap chopper are less prone to abrasion, and the service life of the cutting edges is prolonged; when the scrap chopper is used for cutting strip materials of different thicknesses, edge gaps can be adjusted conveniently by adjusting the static blade, and the long-term continuous production requirements of the tension leveling machine can be satisfied.

Description

technical field [0001] The invention relates to a device used together with disc shears in the complete set of equipment for aluminum foil stretch bending straightening machines to process waste edges of aluminum foil and ensure long-term continuous production of the stretch bending straightening machine. Specifically, it is a stretch bending straightening device. Machine crushing side shearing device. Background technique [0002] During the working process of the aluminum foil stretch bending straightening machine, after the aluminum foil is cut by the disc, the waste edge is cut off by the edge cutter and then recycled. At present, the following are usually used: (1) Single-drum edge cutting shears, which have a simple structure, the lower cutting blade is fixed, and the upper cutting blade rotates (both cutting blades are straight blades). When cutting, the impact is large, the noise is large, and the cutting edge is easy to become blunt. (2) Drum scraping shears, ...

AI Technical Summary

Problems solved by technology

When cutting, the impact is large, the noise is large, and the cutting edge is easy to become blunt

(2) Drum scraping shears, which have small impact and low noise when shearing, but their structure is relatively complicated. In order to prevent the phenomenon of biting the knife, it is necessary to install a mechanism that specifically eliminates the backlash of the gear. Finally, after the cutting blade becomes dull, grind it The cutting edge is difficult, and it is also time-consuming and laborious to adjust the cutting edge gap, which is inconvenient
