Abstract

The invention relates to a cutoff device, which comprises a rack, a sliding guide rail, conveyor belt mechanisms, a cutter rod, two cutters and a cutter driving mechanism, wherein the sliding guide rail is arranged on the rack; the conveyor belt mechanisms are arranged on two sides of the sliding guide rail; the two cutters are symmetrically arranged on the cuter rod above the sliding guide rail in a sliding mode; the cutter driving mechanism comprises a pneumatic rod, a guide slope and a spacing roll, wherein the pneumatic rod drives the cutter rod to vertically slide on the cutoff rack; the guide slope is arranged on the back of the cutters; the spacing roll is arranged on the rack and is in touch connection with the guide slope; the conveying surfaces of the conveyor belt mechanisms are opposite to the two side surfaces of the sliding guide rail; the conveying surfaces are provided with vertical stripes used for increasing conveying static frictional force; and when the two cutters downwards move, the two cutters simultaneously approach to the sliding guide rail under the action of the guide slope and the spacing roll. According to the cutoff device disclosed by the invention, a U-shaped raw material paper board can be cut off at a fixed length, the working efficiency is higher, and the requirement of the cutoff operation can be satisfied.

Description

technical field [0001] The invention relates to a cutting device. Background technique [0002] Coiled steel needs to be protected by wrapping when it leaves the factory, and paper corners are often used. Existing paper corner protectors usually process one side of origami with an L-shaped cross-section into a zigzag shape, and the generated paper corner protectors can be naturally curled when wrapping the sides of the coiled steel and then fully bonded to the sides of the coiled steel, which can effectively Protect the coiled steel by wrapping. However, a large amount of useless cardboard scraps will be generated in the process, resulting in great waste. In order to overcome the above problems, the applicant in this case cut the middle surface of the U-shaped raw cardboard according to the zigzag pattern, and separated the hard origami after cutting the middle surface, and then formed two L-shaped paper corners. This process does not exist. Waste, more economical and env...
