Description

Make things convenient for pressure regulation's paper conveying part

Technical Field

The utility model relates to the technical field of paper conveying equipment, in particular to a paper conveying part convenient for pressure adjustment.

Background

In paper processing, paper conveying equipment is generally used when paper is conveyed, most of paper pressing and conveying parts have basically the same structure, the lower belt is powered, the upper belt is passive and unpowered, and the lower belt rotates to drive the upper belt to rotate through friction between paper and the belt between the upper belt and the lower belt (see figure one). The disadvantage of this is that the middle paper is adversely affected, and after all, the belt power is transmitted through the middle paper, so that the surface of the paper is seriously damaged, and the skin is poked.

Usually the upper belt needs to be powered in two ways; one is that the upper belt is also added with a power motor (see figure two) which is the same as the lower belt, thus the structure is complex and the cost is high. The other is that the power of the lower belt is transmitted to the upper belt through a chain and a reverse gear, the repeated winding structure of the power transmission chain on a machine wallboard is quite complex, and the upper belt cannot move back and forth randomly (see the third picture), so that the size of the paper box or paper to be pressed is adjusted, and the structure is also not ideal; in addition, the belt pressure of the conveying part usually adopts tension springs to tighten rollers on the upper belt and the lower belt to fix a spring, so that the purpose of compacting paper and paper boxes is achieved when the middle paper box passes through the belt and the rollers. Two groups of springs and an adjusting hand wheel are needed for one unpowered roller, and at least 20-28 groups of springs and the adjusting hand wheel are needed for one pressing and conveying part (see fourth). When the belt pressure is regulated, the regulating hand wheel needs to be moved 20-28, and the complicated operation pressure is not uniform. In addition, the spring and the regulating hand wheel are changed into air cylinders, so-called pneumatic pressing tables (see third). The advantages are two points, namely, the pressure is conveniently adjusted in place in one step, and the pressure is uniform. However, the cost is high, 20-28 cylinders are needed for one pressure feeding part, the air pipe is complex to arrange, the space is occupied, and the failure rate is high.
