Automatic control method for temperature and pressure of hot air seam sealing machine

Abstract

The invention relates to an automatic control method for the temperature and the pressure of a hot air seam sealing machine. The method comprises the steps that temperature parameters and pressure parameters are preset on a control interface; a temperature detection element detects the temperature of air in real time and transmits a temperature signal to the control interface during heating of a heating tube; a pressure detection element detects the pressure in the heating tube in real time and transmits a pressure signal to the control interface; and the control interface processes the temperature signal fed back by the temperature detection element or the pressure signal fed back by the pressure detection element, outputs a control signal, and controls the hot air seam sealing machine towork according to the preset temperature or the preset pressure. The automatic control method has the effect of improving the product machining quality of the hot air seam sealing machine.

Description

technical field [0001] The present application relates to the technical field of hot air seam sealing machines, in particular to an automatic control method for the temperature and pressure of the hot air seam sealing machines. Background technique [0002] The hot air seam sealing machine is mainly used for seam processing of windbreaker, sportswear, ski suit, waterproof cap and other waterproof clothing. Before use, it is necessary to set the appropriate temperature and pressure according to the product type to ensure the processing quality of the product. Specifically, first control the heat pipe of the hot air seam sealing machine to heat the air through PLC until the air temperature reaches the temperature value required by the product; then adjust the pressure regulating valve of the hot air seam sealing machine until the air volume is appropriate; The surface of the product is processed and rotated by the upper and lower pressure rollers of the hot air seam sealing m...

AI Technical Summary

Problems solved by technology

[0003] At present, the temperature and pressure control methods of the hot air seam sealing machine process mainly rely on human experience to set parameters, and it is difficult to monitor the temperature and pressure changes in the hot air seam sealing machine process in real time, making it difficult to control the amplitude fluctuations of temperature and pressure. It is found that the processing temperature or pressure of the hot air seam sealing machine is difficult to match the processing conditions of the product, which affects the processing quality of the product

[0004] In view of the related technologies mentioned above, the inventor believes that the temperature and pressure control methods of the hot air seam sealing machine are mainly manual control, and it is difficult to monitor and find changes in temperature or pressure in real time, which affects the quality of product processing.
