Control system and method for axial tension degree of heat shrink tube

Abstract

The invention discloses a control system for the axial tension degree of a heat shrink tube. The control system comprises a conveying roller set used for conveying the heat shrink tube, a heating furnace used for heating the heat shrink tube, an expansion mold used for expanding the heat shrink tube, and a traction roller set for providing tension traction force for the heat shrink tube. The control system is characterized in that the control system further comprises a sensor, a controller and a pressure regulating mechanism, wherein the sensor is arranged on the traction roller set and used for detecting the torque value of the traction roller set; the controller is connected with the sensor and used for comparing the torque value with a preset torque value range, and the inflation air pressure in the heat shrink tube is controlled according to comparison results; and the pressure regulating mechanism is connected with the controller and used for regulating the air pressure in the expansion mold. According to the control system, the axial tension degree of the heat shrink tube in the expansion process can be monitored, regulating is carried out according to monitoring results, andtherefore the product quality of the heat shrink tube is improved.

Description

technical field [0001] The invention relates to the field of heat-shrinkable tubes, in particular to a system and method for controlling the axial stretching degree of the heat-shrinkable tubes. Background technique [0002] Heat-shrinkable tube is a special heat-shrinkable sleeve with high-temperature shrinkage, softness, flame-retardant, insulation and anti-corrosion functions. Eclipse etc. [0003] At present, in the expansion production process of heat-shrinkable tubes, the axial stretch degree of heat-shrinkable tube products is an important index to calibrate the production quality of finished heat-shrinkable tubes. Shrunk products. [0004] However, during the expansion production process of general heat-shrinkable tube products, the axial stretch degree of the product is only detected at the end of the finished heat-shrinkable tube, and the axial stretch degree of the middle part of the product cannot be monitored and controlled online, so the heat shrinkage cannot...

Problems solved by technology

[0004] However, during the expansion production process of general heat-shrinkable tube products, the axial stretch degree of the product is only detected at the end of the finished heat-shrinkable tube, and the axial stretch degree of the middle part of the product cannot be monitored and controlled online, so the heat shrinkage cannot be guaranteed. Whether the axial stretch of the finished pipe is qualified
