Description

technical field [0001] The invention relates to the technical field of heat shrink tube processing equipment, in particular to a processing equipment. Background technique [0002] The axial stretch rate of heat-shrinkable tubing is one of the important indicators to measure its quality. With the continuous improvement of automation in various industries, the process of using heat-shrinkable tubing in the downstream factories of the industrial chain gradually adopts automated equipment to replace the transmission process. The development and application of equipment has gradually increased the quality and consistency requirements of heat shrinkable tubes. Heat shrinkable tubes with an unstable axial stretch rate will seriously affect the operation stability of subsequent automation equipment and will inevitably be eliminated by the market. [0003] In the related art, the heat shrinkable tube dry expansion machine production line generally consists of three parts: a tube unw...

AI Technical Summary

Problems solved by technology

Heat-shrinkable tubing needs to go through main processes such as masterbatch, extrusion, irradiation, expansion, and packaging during the processing process. During the expansion process, the stretch rate of the heat-shrinkable tube changes dynamically, and the stretch rate cannot be effectively controlled.

At the same time, after the heat-shrinkable tube undergoes a series of processes before expansion, the original tube will continue to accumulate defects of uneven axial stretch rate, and conventional heating methods cannot eliminate the problem of unstable axial stretch rate during expansion. Defects, these defects will cause the axial stretch rate of the finished heat shrinkable tube after expansion to be unstable, resulting in product quality problems
