Automatic glue scraping device

Abstract

The invention particularly relates to an automatic glue scraping device applied to printing and packaging machinery. The automatic glue scraping device is characterized in that a middle scraper is arranged on an ejection rod of a first feeding air cylinder which is arranged at the front end of a middle scraper carrier; a left and right scraper carrier platform is arranged at upper ends of lower sliders which are arranged on a lower screw rod, and a left scraper carrier and a right scraper carrier are arranged on left and right sides of the front end of the left and right scraper carrier platform respectively; a left scraper is arranged on an ejection rod of a second feeding air cylinder which is arranged at the front end of the left scraper carrier; a right scraper is arranged on an ejection rod of a third feeding air cylinder which is arranged at the front end of the right scraper carrier; two supporting arms of the middle scraper carrier penetrate two supporting arm grooves, and the bottom of the middle scraper carrier is mounted on two linear bearing guide rails through linear bearings; a platform supporting column is arranged at the bottom of each of four corners of the left and right scraper carrier platform, and bottoms of the platform supporting columns are mounted on the two linear bearing guide rails through the linear bearings. The automatic glue scraping device has advantages of flexibility, convenience, high automation degree and effectiveness in glue removal.

Description

technical field [0001] The invention belongs to the field of glue removing devices, and in particular relates to an automatic glue scraping device applied to printing and packaging machinery. Background technique [0002] For printing and packaging machinery such as tape machines and coating machines, glue will remain on the rollers during operation. If it is not cleaned for a long time, the glue will accumulate more and more, resulting in unstable product quality. The traditional solution is to stop the machine for manual glue removal. Not only time-consuming and labor-intensive, but also the degumming effect is poor and unstable, and the roller is easily damaged during manual degumming. Contents of the invention [0003] The purpose of the present invention is to solve the defects that the current printing and packaging machinery needs to stop for manual degumming when degumming, which has long degumming time, poor degumming effect and instability, and provides an automa...

Problems solved by technology

[0003] The purpose of the present invention is to solve the defects that the current printing and packaging machinery needs to stop for manual degumming when degumming, which has long degumming time, poor degumming effect and instability, and provides an automatic glue scraping device, which is driven by a motor and a guide rail The scraper moves left and right, and the cylinder drives the scraper to move back and forth, and automatically removes the glue from the rotating roller, without stopping the machine. The glue removal speed is fast and the quality is good.
