High-precision automatic cutting machine for paper products and working method thereof

Abstract

The invention relates to a high-precision automatic cutting machine for paper products and a working method thereof. The high-precision automatic cutting machine for the paper products comprises an independent unwinding machine, a cutting machine body and a control system, wherein the independent unwinding machine and the cutting machine body are sequentially connected from front to back; the cutting machine body comprises a traction mechanism, a transverse cutting assembly, a longitudinal cutting assembly and a discharging mechanism; the front end of the traction mechanism is connected with the independent unwinding machine; the rear end of the traction mechanism is connected with the discharging mechanism; the traction mechanism is composed of two pinch roll sets; a deviation rectifyingmechanism is arranged between the two pinch roll sets; the transverse cutting assembly and the longitudinal cutting assembly are sequentially arranged between the traction mechanism and the discharging mechanism from front to back; and tension detection modules are arranged on the independent unwinding machine and the pinch roll sets. According to the high-precision automatic cutting machine for the paper products and the working method thereof provided by the invention, the structural design is reasonable, the working method is simple, the automation degree is high, real-time adjustment and position deviation rectification are conducted on tension in the unwinding and traction process, the production efficiency and the precision are improved, and the prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of cutting machines, and in particular relates to a high-precision automatic cutting machine for paper products and a working method thereof. Background technique [0002] The automatic cutting machine is used for the division and cutting of sheets in various industries. It has a high automation program and is easy to operate. It is a cutting equipment used in many industries, such as the paper industry. The paper industry is one of the important components of the national economy. In the past two decades, my country's paper industry has achieved leapfrog development. According to a survey by the China Paper Association, the total output of machine-made paper and cardboard in the country (excluding Hong Kong, Macao and Taiwan) in 2019 was 106.3022 million tons. In the papermaking process, cutting machine-made paper and cardboard for paper products is one of the important processes. The key equipment in th...

Problems solved by technology

[0003] At present, most domestic cutting machines have a single structure, little consideration for personalized design, inconvenient operation, low cutting accuracy, and there is still room for improvement in deviation correction control, cutting form, etc. With the development of market demand, it is necessary to develop A high-precision automatic cutting machine for paper products and its working method, so as to solve the above technical problems

[0004] Chinese patent application No. CN201220238875.1 discloses a paper cutter, which includes a paper cutter moving guide rail, a paper cutter motor, a paper cutter timing belt, a moving slide, a paper cutter support arm, a paper cutter blade, and a control cutter. The paper cutting motor that rotates the paper blade has a low degree of automation and intelligence, and it does not solve the problems of inconvenient operation and poor mobility of the cutting machine
