AI Technical Summary
Existing sewing machines are prone to thread breakage during the stitching process, resulting in high costs and low consistency in the sewing process.
The intelligent anti-bird's nest method is adopted to cancel the electronic thread clamp. Through the cooperation of the thread shifting mechanism and the thread return mechanism, the control system shifts the thread end to the top of the presser foot after the thread cutting action, and adjusts the thread end length through the thread return mechanism. When the needle enters under the needle plate, it is brought under the needle plate by the rotary shuttle and the thread return mechanism to realize the length and position adjustment of the thread end.
It reduces the occurrence of bird's nest yarn balls, avoids thread waste, improves the quality and consistency of the sewing process, and reduces overall costs.

[0004] The present application aims to provide a kind of intelligent bird nest cancellation method of electronic thread clamp to solve the above problems.
[0005] To achieve the above object, the present application provides the following technical scheme: a kind of intelligent bird nest cancellation method of electronic thread clamp, including head and control system, head is provided with rotating shuttle, needle plate, needle, thread shifting mechanism, loop mechanism and face line, loop mechanism is used to realize clamping action and loop action, executes the following steps: S1: control system in the process of cutting thread action or after cutting thread action, thread shifting mechanism is moved to the needle residual thread head above presser foot, and during this period, according to the length control requirement of thread head, loop mechanism makes or does not make thread length adjustment to the thread head of face line; S2: when starting sewing, needle enters below needle plate from top to bottom, while rotating shuttle rotates, by rotating shuttle and / or loop mechanism cooperation, the thread end of face line is brought into below needle plate, so that the length adjustment and position adjustment of this time thread end of face line are completed.
[0006] Further, the movement of needle is driven by the main shaft of sewing machine, and the control system of sewing machine can control the rotation of main shaft.
[0007] Further, the driving source of loop mechanism is step motor or servo motor or electromagnet or air valve.
[0008] Further, the driving source of thread shifting mechanism is step motor or servo motor or electromagnet or air valve.
[0009] The present application has the beneficial technical effects that: the sewing machine anti-bird nest action is realized through the thread supply amount detection sensor, the anti-bird nest assembly and the anti-bird nest control device, the occurrence of the bird nest thread ball and the sewing broken needle during the sewing process are reduced, and the sewing quality during the sewing process is ensured; the thread waste is eliminated and the thread processing trouble is reduced through the thread return instead of the thread cutting; the thread return amount of the thread return part is ensured and the thread return precision is improved through the monitoring of the thread length by the thread supply amount detection sensor and the cooperation of the thread return part and the thread clamping part to ensure the thread tension of the face thread during the thread return.
