Folding machine

Abstract

The invention relates to a folding machine which comprises a rack and a folding device. A paper conveying device is arranged on the rack and comprises an upper-layer paper conveying device and a lower-layer paper conveying device. The upper-layer paper conveying device comprises a mounting rack and transmission rollers. A tightening device is arranged on a transfer roller and comprises a first tightening roller, a second tightening roller, a third tightening roller and a tightening belt, the tightening belt is mounted on the first tightening roller, the second tightening roller, the third tightening roller and the transfer roller, and the third tightening roller and the lower-layer paper conveying device are located on the same plane. The folding device comprises a folding knife drive device, and the folding knife drive device comprises a motor and a mounting seat. The mounting seat comprises a motor mounting seat and a knife rod, and the knife rod is mounted on the motor mounting seat. A knife retracting device is arranged between the motor mounting seat and the knife rod. Knife discs are mounted at one end of the knife rod, and a folding knife mounting groove is formed on each knife disc. The folding machine is ingenious in structure and high in stability, the folding efficiency and effect of the folding machine can be effectively guaranteed, and application and popularization of the folding machine in the market are facilitated.

Description

technical field [0001] The invention relates to the technical field of folding machines, in particular to folding machines. Background technique [0002] Folding machine is a modern printing equipment produced with the modern printing industry. Modern printing plants usually include three processing procedures: pre-press, printing, and post-press. The main carrier medium is paper. Due to the rise of packaging printing, on other material media, Such as plastics, fabrics, leather, metal surfaces, etc. are also on the rise, but the main carrier is still dominated by paper. Printing industry processing is usually divided into book and newspaper processing and packaging processing. Folding machines are mainly used for folding paper of various sizes and thicknesses within the design range. It is suitable for high-volume printing centers, production enterprises, official documents, business letters, etc. of the fold. [0003] The folding machine is mainly composed of a paper sepa...

AI Technical Summary

Problems solved by technology

[0003] The folding machine is mainly composed of a paper separation system, a paper feeding system, a curved parallel folding system, a vertical folding knife folding system, a frame, a transmission system, an electrical control system, and a post receiving system. During the folding process, due to the poor stability of the transportation device used to transport the products to be folded, the products to be folded placed on the transportation device are often scattered and dropped, and the folding knife is not fixed stably during the folding process, resulting in folding The page efficiency is low, the folding effect is poor, and the phenomenon of resource waste abounds, which is not conducive to the promotion and application of folding machines in the market.
