Bottom paper and top paper synchronous paper feeding device and control method

Abstract

The invention provides a synchronous body paper and face paper feeding device and a control method. The device is characterized in that a face paper front lay gauge, a face paper pressing wheel, a face paper side lay gauge, a body paper front lay gauge and a body paper lifting plate assembly are configured with cam mechanisms respectively and are driven by the respective cam mechanisms; a face paper motor drives a low-speed face paper feeding belt assembly, a body paper induced draft air distribution valve, a face paper side pull gauge and cam mechanisms thereof through a synchronous toothed belt or a roller chain; a paper injection driving roller, an upper pressing driving roller, a paper feeding driving roller, a high-speed face paper injection wheel and a high-speed face paper conveying belt assembly are driven by a body paper motor at the same speed. The distance between the face paper front lay gauge and a laminating roller is equal to the distance between the body paper front lay gauge and the laminating roller, so that body paper and face paper reach a converging point at the same time, and surface lamination is completed. The functions of synchronously feeding the body paper and the face paper at a high speed and automatically aligning the body paper with the face paper can be realized, the use of the motors is reduced, and the phenomenon that the motors are frequently started is avoided. The working efficiency is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of corrugated cardboard equipment, and relates to a paper feeding system for overlay processing in the corrugated cardboard processing process, in particular to a synchronous paper feeding device and control method for the bottom paper and surface paper of the corrugated cardboard. Background technique [0002] During the cladding process of corrugated cardboard, at least two edges must be aligned when the backing paper and face paper are laminated. Generally, the method of aligning the front edge and one side edge is adopted. [0003] At present, the conveying of the backing paper and the top paper are respectively driven by two sets of drive systems, and the two drive systems are not synchronous. That is to say, adjust the limit plate of the surface paper side pull gauge and the side baffle of the bottom paper to the same position, and the side is always aligned during the entire conveying process of the b...

Problems solved by technology

[0004] In this cardboard processing method, the cover lamination of each cardboard, the bottom paper feeding motor, the air distribution valve motor and the face paper feeding motor must be started and stopped once. Such frequent starting and stopping have higher performance requirements for the motor and are also Increased the start-stop control link of the motor, especially affecting the processing efficiency
