High-effectively production roll paper core deformation repair device and method

Abstract

The invention provides a high-efficiency production roll paper core deformation repair device and method. The device comprises a drill bit, a transmission shaft, a locating sleeve and a handheld electric drill. The drill bit is composed of a section A and a second B. The section B is provided with sawteeth. The section B serves as the connecting end. The transmission shaft is a hollow cylindrical tube. The ends C and D of the transmission shaft are both provided with fixing screw holes. The section B of the drill bit is connected and fixed to the end C of the transmission shaft through a fixing sleeve. The locating sleeve is arranged on the transmission shaft and can move back and forth on the portion, between the screw holes of the two ends C and D of the transmission shaft, of the cylindrical tube. The end D of the transmission shaft is further provided with a connector. The handheld electric drill clamps the connector through a drill chuck to provide rotating power for the repair device. After deforming, a roll paper core tube can be quickly repaired through the device and method provided by the invention so that a paper core shaft can smoothly and rapidly penetrate through the roll paper core tube. The high-efficiency production roll paper core deformation repair device ensures normal use of roll paper, is easy to operate and fast and convenient to maintain and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the field of web printing production, in particular to a device and method for repairing deformation of a web core for efficient production. Background technique [0002] At present, the web is mainly used for high-volume and efficient production of rotary printing machines, ranging from newspapers, books, magazines, to bills and labels. The web mainly includes a paper core tube and a printing substrate wound around the paper core tube. Material. [0003] In the prior art, the feeding part of the rotary printing machine is that an air shaft passes through the paper core tube of the web, and then the paper core tube is locked on the air shaft by compressed air. There are mainly two types in the actual production process. The specifications of paper core tubes are 3 inches and 6 inches respectively, and the specific use is selected according to customer requirements and product conditions. Since the paper core tube is mainly ma...

Problems solved by technology

[0004] 1. It is time-consuming and labor-intensive for the air shaft to pass through the paper core tube, and it may even fail to pass through the paper core tube, resulting in return of goods, which affects the production effect and increases operating costs;

[0005] 2. The original perfect circle of the paper core tube of the roll paper becomes an ellipse or an irregular circle, so that the roll paper will swing during the rotation process, resulting in abnormal printing

In this way, in the normal production process, one or more sets of paper mandrels provided in the above-mentioned schemes need to be prepared, which will undoubtedly increase operating costs. At the same time, it is necessary to switch between the air shaft and the paper mandrel provided in the above-mentioned solutions, which will undoubtedly increase the workload and cause a certain amount of inconvenience

[0007] However, the technical solution disclosed in the Chinese utility model patent CN202829045U retains the function of the original air expansion shaft in the feeding part of the printing machine, refits the feeding part, adds two sets of air cap devices and related supporting parts, and realizes deformation through the gas cap device The paper core tube is repair-free and roll-up production. This kind of transformation will undoubtedly increase the transformation cost and increase the floor space of the original paper upper part.
