Thread clamp assembly for a sewing machine and sewing machine

By using an electromagnet assembly to drive the thread release lever and top column structure, combined with the adjustment of the nut and rubber pad, a uniform distribution of the thread clamping force is achieved on the sewing machine. This solves the problem of unevenness in traditional mechanical thread clamps, improves sewing quality, and reduces the thread breakage rate.

AI Technical Summary

Technical Problem

Traditional mechanical thread clamps cannot guarantee a uniform distribution of clamping force on the contact surface of the clamping disc, resulting in uneven sewing quality and a high thread breakage rate.

Method used

An electromagnet assembly drives the wire release rod to move. Force is transmitted through limit blocks and evenly distributed top columns, so that the wire clamping plate is stably connected to the main wire clamping plate, achieving a uniform distribution of clamping force. Combined with nuts and rubber pads, the space of the wire passage area is adjusted, and the clamping force is adjusted in segments by electronic control.

Benefits of technology

It achieves a uniform distribution of thread clamping force on the thread clamping plate, improves sewing quality, reduces thread breakage rate, and ensures the stability and adjustability of thread clamping force in different sewing zones.

Abstract

The utility model provides a kind of thread clipper assembly of sewing machine and sewing machine, belong to sewing machine electronic thread clipper technical field.It solves how to make the clamping force more uniform etc. technical problems that thread clipper is transmitted on it.The thread clipper seat is connected with thread clipper shaft, thread clipper shaft inside is equipped with thread pressing pin, electromagnet component can drive thread pressing pin left and right movement by thread loosening rod, one end of thread pressing pin is connected with thread loosening rod, the other end of thread pressing pin is connected with limit block, limit block is abutted or connected with thread pressing disc.The utility model moves thread loosening rod by electromagnet component drive, make thread pressing pin move left and right, limit block moves along with thread pressing pin, by limit block and thread pressing disc abut or connect, so that thread pressing disc can receive uniform thrust, thread pressing disc transmits force to main thread clipper disc, main thread clipper piece moves to vice thread clipper piece after receiving pressure and compresses the space of threading area, to reach the function of clamping thread.
