High-precision servo conveying dust removal paper feeding machine

Abstract

The application discloses a high-precision servo conveying dust-removing paper feeding machine and relates to the technical field of corrugated paper processing equipment. The paper feeding deviation correcting mechanism is used for correcting the conveying position of the corrugated paperboard. The paper feeding deviation correcting mechanism, the one-section paper feeding mechanism, the two-section air suction conveying mechanism and the three-section servo auxiliary conveying mechanism are arranged. The three-section servo auxiliary conveying mechanism plays a key role in conveying small-size corrugated paperboard and warped paperboard. The air suction area is small during the paper feeding process of the small-size paperboard. In addition, the paper feeding precision of the warped paperboard is worse than that of the large paperboard. When the paperboard is conveyed to the two-section air suction box and the three-section servo auxiliary conveying mechanism, the two-section air suction box can be adjusted up and down and the three-section servo auxiliary conveying mechanism clamps the corrugated paperboard for conveying. When errors occur, all the servos participating in the paper feeding can be corrected in real time through the motion control system, the paper feeding precision can be extremely high, the economic benefits are met, the application prospect is wide, and the production yield of the corrugated paperboard is ensured.

Description

TECHNICAL FIELD

[0002] Corrugated paper is a board-shaped object bonded by face paper and corrugated paper formed by corrugated roller, generally divided into single, double and three-layer corrugated paper board three categories, divided into A, B, C, E, F five types according to the size of corrugation. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, convenient storage and transportation, etc. More than 80% of corrugated paper can be recycled, and corrugated paper can be used for packaging of food or digital products, which is relatively environmentally friendly and widely used.

[0003] At present, when customers customize corrugated paper, they usually require printing patterns on the corrugated paper, which requires the use of corrugated paper printing equipment. Since the front end of the paper board of the corrugated paper printing equipment has a front stop positioning, it ensures that only one paper board can pass through each time. When the lowermost paper is sent forward, it will generate friction with the second paper board below, and the second paper board will be driven forward and hit the front stop plate to be limited from entering. The height of the paper board stack is constantly changing, the friction between the first paper board and the second paper board below is also constantly changing, and the force of the second paper board hitting the front stop is also constantly changing. Since the edge of the paper board is flexible, the initial positioning of each paper board changes, and the slipping of the paper feeding wheel, two uncontrollable factors directly affect the paper feeding accuracy, resulting in increased paper board scrap rate, slow production speed, increased equipment operation difficulty and labor intensity. The paper feeding method of the present application has absolute guarantee for the physical indicators such as surface pressure, breaking resistance and edge pressure of the paper box after being made into a paper box, which means that under the precondition of meeting the above physical indicators, the paper usage can be saved by 5-20%.
