Paper deviation rectifying device and deviation rectifying method

Abstract

The invention discloses a paper deviation rectifying device and a deviation rectifying method. The paper deviation rectifying device comprises a rack; at least one deviation rectifying steel roller set used for paper to bypass is vertically arranged on the front side of the rack, electric eye deviation rectifying devices used for paper to pass and detecting whether the paper deviates or not are further arranged on the deviation rectifying steel roller sets, and movable supporting seats are arranged at the two ends of the deviation rectifying steel roller set; and the movable supporting seats are connected with sliding blocks through bearings, two guide columns penetrate through the sliding blocks, pushing air cylinders are further arranged on the rack, and the pushing ends of the pushing air cylinders are connected with the sliding blocks. The paper deviation rectifying device has the beneficial effects that during deviation rectifying, the pushing air cylinders push the sliding blocks, the deviation rectifying steel roller sets are forced to turn over relative to the bearings along with movement of the sliding blocks, the deviation rectifying steel roller set is inclined integrally, the paper is driven to rectify deviation, and the problem of uneven tension is well solved.

Description

technical field [0001] The invention relates to the field of paper tube making machine equipment, in particular to a paper deviation correcting device and method. Background technique [0002] The tube making machine is a special equipment for producing paper bag tubes with pasted bottoms. It can produce paper tubes with trapezoidal ends and flat ends. The paper tubes made are suitable for packaging cement, chemical fertilizers, flour and other powders or granules. Shaped materials, thus gaining people's wide welcome. [0003] When the tube making machine is working, because the strip-shaped paper is easily affected by uncontrollable forces during the conveying process, it will deviate laterally from the original preset reference line, showing a serpentine lateral deviation, which seriously affects the quality of paper processing. Accuracy and continuity of normal operation of production equipment, therefore, the paper needs to be corrected during the conveying process. ...

Problems solved by technology

[0003] When the tube making machine is working, because the strip-shaped paper is easily affected by uncontrollable forces during the conveying process, it will deviate laterally from the original preset reference line, showing a serpentine lateral deviation, which seriously affects the quality of paper processing. Accuracy and continuity of normal operation of production equipment, therefore, the paper needs to be corrected during the conveying process

[0004] The deviation correction device in the prior art generally uses a tension roller for deviation correction, but there is a problem of uneven tension in the way of using the tension roller for deviation correction, resulting in poor deviation correction effect
