Novel middle waste absorbing punching roller

Abstract

The invention discloses a novel middle waste absorbing punching roller. The novel middle waste absorbing punching roller comprises an upper punching roller body, a lower punching roller body and a waste outlet. The upper punching roller body and the lower punching roller body are hollow rollers. The waste outlet is communicated with the lower punching roller body. The upper punching roller body and the lower punching roller body are provided with an upper punching die and a lower punching die respectively, and the upper punching die and the lower punching die are meshed with each other. The novel middle waste absorbing punching roller has the advantages of being high in speed and precision and low in noise, the working efficiency can be improved, and the comprehensive cost can be lowered.

Description

technical field [0001] The invention relates to the field of web printing, in particular to a novel intermediate waste-absorbing punching roller. Background technique [0002] refer to Figure 1 to Figure 4 At present, the punching roller in the domestic and foreign markets consists of an upper punching shaft 100, a lower punching shaft 200, an upper punching plate 300, a lower punching plate 400, a guide wheel 500, a waste suction plate 600, a waste suction pipe 700, and a support frame 800. The upper die 301 (male die) is installed on the upper punching plate 300, the lower die 401 (female die) is installed on the lower punching plate 400, the paper passes through the middle of the upper and lower punching plates, the paper is punched by the upper and lower dies, and the punched waste falls to The waste suction tray 600 is sucked from the waste suction pipe 700 . There are more gaps between the rollers of this structure, and the noise is larger when running at high speed....

AI Technical Summary

Problems solved by technology

There are more gaps between the rollers of this structure, and the noise is louder when running at high speed

When running at high speed (600m / min), more waste will block the waste area, so that the waste will fall from the gap between the waste suction plate and the lower punching plate to the outside of the workstation

In this way, the appeal problem can only be improved by reducing the running speed of the roller (300m / min), but this will reduce the work efficiency

It is not difficult to see that there are defects such as slow punching roller speed, insufficient precision and high noise in the prior art
