The existing thread pressing equipment mostly adopts manual or semi-automatic operation, mainly through heating elements to heat the sewing thread to a molten state, and then through a pressure roller to press the molten sewing thread onto the fabric to form a firm sewing stitch. Traditional thread pressing equipment usually uses resistance wire or heating plate as heating element, which heats the sewing thread to the required temperature by electric current. At the same time, a pressure roller or a pressure plate is used to apply pressure to the sewing thread to make it tightly combined with the fabric.

[0003] The existing pressure roller or pressure plate design is often not flexible enough to accurately adjust the pressure according to different sewing thread materials and thicknesses, which will affect the final thread pressing quality. SUMMARY

[0014] 2、the driving shaft can be coaxially designed with the transmission equipment of the sewing thread through the driving pulley, the synchronous belt and the driven pulley, which ensures that the rotation speed of the press line and the transmission speed of the sewing thread are consistent, and avoids the problem of stretching or breaking of the sewing thread caused by different speeds.

[0015] 3、the synchronous belt adopts the design of loose belt, which can maintain good transmission effect even when the relative position of the press roll connecting plate and the press roll lifting support changes, and reduces the maintenance frequency. BRIEF DESCRIPTION OF DRAWINGS
