Automatic feeding sewing machine

Abstract

The invention discloses an automatic feeding sewing machine. The automatic feeding sewing machine structurally comprises a yarn feeding wheel belt frame plate, a material supporting truss block, a sewing machine suspension arm, a speed regulation wheel disc, a yarn rope strand disc seat, a folding buckle pull rod strip and a base column block. According to the automatic feeding sewing machine, the yarn feeding wheel belt frame plate is matched with the material supporting truss block, the adaptive needle threading operation is carried out through sewing cloth; in lead wire feeding, through the cooperation of a convex pin block spinning yarn winding and the axial movement of a feeding cap nozzle fan plate wheel disc frame and a push rod spring ring frame, the rotation operation of a lining channel yarn clamping frame wheel belt shaft guiding a same-angle-distance rotating disc buckle to be matched a supporting pad is achieved, so that the continuity of subsequent yarn feeding is guaranteed; and when the yarn is driven to generate a threading and yarn tightening phenomenon, a spring bead wire ring groove is pressed and pushed through a bevel shifting piece rod to form a shaft-disengaging type rotor for accelerating yarn supply operation, so that it is guaranteed that a single yarn is prevented from being broken, the winding compactness of spun yarn is improved, cracking is avoided, the yarn feeding continuity is guaranteed, the effect that needle feeding belt yarn penetrates through cloth to prepare lace edges is improved, and the attractiveness of the cloth and the smooth yarn comfort are guaranteed.

Description

technical field [0001] The invention is an automatic feeding sewing machine, which belongs to the field of sewing machines. Background technique [0002] The yarn feeding of the sewing machine is the key for low-level supplementary sewing and threading, which ensures the continuous supply of thread materials for needle thread traction, improves the precision and sensitivity of the sewing machine during continuous operation, and also improves the integrity and beauty of finished product preparation. Degree, the shortcomings of the current technology to be optimized are: [0003] The automatic yarn feeding of the sewing machine is easy to cause high-risk yarn drawing toughness and excessive tension due to the low-level liner input fabric and sewing operation, resulting in cracked yarn entanglement, resulting in subsequent needle threading with strands entangled knots piled on the surface of the fabric After the operation of affecting the sewing and processing cloth, the surfa...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an automatic feeding sewing machine to solve the problem that the automatic yarn feeding of the sewing machine is easy to cause the high-risk tension of the yarn drawing toughness to be too high due to the low liner board input cloth and the sewing operation. The entanglement of the cracked silk thread will cause the subsequent threading and threading to have knots entangled with the strands to pile up on the surface of the fabric, which will affect the sewing and processing of the fabric. Insufficient feeding fineness for sewing processing, and the problem of plugging and entanglement of the shedding yarn end caused by the wheel guide and cap mouth of the hanging yarn feeding
