Brake device of roll-dividing machine

Abstract

The invention discloses a brake device of a roll-dividing machine, and relates to the brake device. The brake device of the roll-dividing machine comprises a supporting frame, brake calipers and a hydraulic cylinder, wherein a cylinder body of the hydraulic cylinder is fixed to the supporting frame; the brake calipers are arranged on the left side and the right side of a track; a linkage mechanism is arranged below the hydraulic cylinder; a push rod is fixed to the lower end of a piston of the hydraulic cylinder; the linkage mechanism is composed of a left portion and a right portion which are symmetrical, and the left portion and the right portion each comprise an upper connecting rod and a lower connecting rod of which one ends are hinged together; the other end of each upper connecting rod is hinged to the lower end of the push rod; the other end of each lower connecting rod is hinged through a fixing pin shaft which is fixed to the supporting frame; and the brake calipers are fixed to the middles of the lower connecting rods of the left portion and the right portion correspondingly. In the brake device of the roll-dividing machine, the linkage mechanism is of a multi-connecting-rod hinge structure, so that the structure and force transmission are more stable. The linkage mechanism is a parallelogram mechanism and has a high gain effect, so that the braking effect is improved.

Description

technical field [0001] The invention relates to a brake device, in particular to a brake device for a winding machine. Background technique [0002] The slitting machine is mainly composed of a frame, an upper knife, a bottom knife and a braking device, which is suitable for cutting plastic products; the frame is equipped with guide rails, and the braking device relies on the guide rails for braking. [0003] The brake device of the slitting machine is an essential device to ensure safe operation. The existing brake device includes a brake groove and a drive cylinder; usually one end of the brake groove is hinged on the frame, and the middle of the brake groove is provided with a bar The brake hook is also hinged on the piston rod through the strip hole to form a clamp-type brake hook brake, which clamps the two sides of the track. The brake hook can be opened to the two outer sides. And lift it above the track surface, so as to avoid the brake hook being exposed at ordinar...

AI Technical Summary

Problems solved by technology

Since the brake channel is hinged with the piston rod through the strip hole, the stability of the hinged structure is low, and the force transmission is unstable, that is, the impact force between the brake channel and the piston rod will be large, resulting in a longer service life of the drive cylinder. short; in addition, the existing braking structure is essentially a lever structure, but it is not a labor-saving lever, so the required braking driving force is relatively large, and the braking effect is not good
