Paperboard die cutting proofing press and method for replacing on-machine test

Abstract

The invention discloses a paperboard die cutting proofing press and a method for replacing on-machine testing, and belongs to the field of paperboard die cutting. The paperboard die cutting proofing press comprises an upper die, a lower die and a driving stamping device, wherein the driving stamping device comprises an air cylinder, an oil cylinder, a bottom plate, two guide columns and an upper plate, the two guide columns are arranged on the bottom plate, the upper plate is arranged at the upper ends of the guide columns, the air cylinder is fixed on the upper plate, the air cylinder is connected with the oil cylinder, and the upper die is arranged above the lower die. Through pre-positioning of the air cylinder and pressurization cutting of the oil cylinder, the situation that the upper die directly and vigorously collides with the lower die by directly using the oil cylinder is avoided, noise is reduced, and the service life of the upper die and the service life of the lower die are prolonged; and the situation of insufficient cutting pressure caused by direct use of the air cylinder is also avoided, and normal cutting of the paperboard is ensured. The die cutting pattern is used for replacing on-machine detection on large-scale production equipment.

Description

technical field [0001] The invention relates to the field of cardboard die-cutting, in particular to a cardboard die-cutting proofing machine and a method for replacing the test on the machine. Background technique [0002] Before the mass production of cardboard die-cutting, it is necessary to carry out a proofing test on the cutting blade to identify whether the blade meets the requirements. However, the start-up of large-scale production equipment is relatively slow. If it is only for a die-cutting proofing test, it is obviously not suitable to directly start the large-scale production equipment for testing. Therefore, a special device is required for die-cutting proofing test to simulate large-scale production equipment. Production equipment for die cutting. [0003] Because the cigarette wrapping paper has high requirements on the indentation and folding resistance after the machine is formed, the main raw material paper of cigarette rods and boxes and the semi-finishe...

AI Technical Summary

Problems solved by technology

There is a large gap between the folding indentation and the die-cutting indentation of the cigarette label, and the difference between the manual folding indentation is also large. It is impossible to accurately determine the indentation folding resistance of paper and semi-finished products, and can only vaguely judge the folding resistance. Others Performance cannot be judged

The second is to place the base paper and semi-finished large-sheet samples on the large-sheet die-cutting equipment in production. It is necessary to match the size of the large-sheet paper with the die-cutting equipment, and then die-cut the large-sheet samples into small box samples. Time-consuming normal production, installation of supporting knife plate mold, the whole process is cumbersome and time-consuming, and the work efficiency is low

However, unlike large-scale production equipment, the devices used for die-cutting and proofing are not designed to be particularly complicated, and often simply use a single power source (such as an oil cylinder, etc.) to provide power

In actual use, it is found that if the driving power of a single power source is too large, it is prone to the problem of high noise and large device loss. However, only by reducing the output power of the power source for adjustment, the output power is likely to be too small The problem of not being able to cut cardboard normally
