Double-edge cutting automatic device and cutting method for special vibration-damping sound-absorbing adhesive tape for high-speed rail carriage

Abstract

The invention relates to a double-edge cutting automatic device and a cutting method for a special vibration-damping sound-absorbing adhesive tape for a high-speed rail carriage. The method comprisesthe following steps of: rotating a transverse moving right hand wheel clockwise or anticlockwise to finally position the distance between a left cutter and a right cutter; rotating a lifting hand wheel clockwise or anticlockwise to finally position the distance between the left cutter and a driving guide roller and the distance between the right cutter and the driving guide roller; correspondinglymounting a left paper tube and a right paper tube on two slip shafts; starting an electromagnetic valve and a pneumatic valve, wherein one path of the pneumatic valve provides an air source for the slip shafts through an air filling gun, and the other path of the pneumatic valve provides an air source for a right water spraying valve and a left water spraying valve through the electromagnetic valve; and starting a left cutter motor assembly and a right cutter motor assembly to cut double edges of the sound-absorbing adhesive tape, and winding waste edges on the left paper tube or the right paper tube, wherein the width of anti-sticking paper of the cut sound-absorbing adhesive tape is not changed, and an aluminum foil and glue are cut according to set sizes. According to the device, the qualified special vibration-damping sound-absorbing adhesive tape for the high-speed rail carriage is produced, the production efficiency is improved by more than ten times, and the requirement on large-batch production is met.

Description

technical field [0001] The invention relates to an automatic device and a cutting method for cutting both sides of vibration-damping and sound-absorbing tapes specially used for high-speed railway carriages. According to the size requirements of finished products, the aluminum foil layers and adhesive layers on both sides of the sound-insulating tapes are cut. Background technique [0002] Due to the high speed of the high-speed railway train, all parts of the car body are doing work, and affected by the climate, rails and various factors, the car body will generate vibration and noise. For the riding environment, the processed vibration-absorbing and sound-absorbing tape is generally used to paste the inner position of the compartment to achieve the purpose of controlling the noise in the compartment. [0003] The processed vibration-absorbing and sound-absorbing tape must meet the geometric dimensions after processing to ensure the safe use range of high-speed rail train c...

AI Technical Summary

Problems solved by technology

[0007] The aluminum foil cut by hand is not neat, has burrs, and there are dimensional errors after the tape is finished; it is difficult to complete the cutting of aluminum foil and glue without cutting the anti-adhesive paper, resulting in a high scrap rate;

[0008] The realization of the finished product is completely manual cutting, which is time-consuming, labor-intensive, and the production efficiency is low, which cannot meet the time and quality requirements of mass production
