An electromagnetic suture tension adjustment device

Abstract

The invention discloses a tension adjusting device for electromagnetic stitches. The tension adjusting device comprises a stitch clamping disc and an installation screw rod and is characterized in that the tension adjusting device further comprises an electromagnetic coil and an armature; the electromagnetic coil and the armature are respectively arranged on two sides of the stitch clamping disc; the installation screw rod penetrates through the electromagnetic coil, the armature and the stitch clamping disc to be fixed on a machine head of a sewing machine; and the tension adjusting device comprises a buffer spring, shielding discs and shielding gaskets. Compared with the prior art, the tension adjusting device for electromagnetic stitches has following advantages: by utilizing a clamping structure in that the electromagnetic coil cooperates with the armature, thrust adjusting operation is performed on the stitch clamping disc conveniently; by installing the buffer spring, adjusting strength of the electromagnetic coil can be effectively absorbed so that the effect of buffering adjusting force is exerted; stability of sewing operation is ensured and occurrence probability of emergencies is decreased; and the shielding disc is configured for avoiding influence of magnetic force generated by the electromagnetic coil on internal parts of the machine head of the sewing machine.

Description

technical field

[0001] The invention relates to the field of garment processing equipment, in particular to an electromagnetic suture tension adjusting device. Background technique

[0002] At present, the sewing machines generally used in industrial sewing, in order to make each sewing thread smoother, a tension adjustment device is usually installed on the sewing machine frame to adjust the tension or slack of the thread passing through the sewing needle. However, this method will be inconvenient to adjust due to the setting of the suture tension adjustment device in application. During the sewing operation, when the operator finds that the tension of some sutures is too loose or too tight and needs to be adjusted, Adjustments have to be made manually, which is extremely inconvenient. Furthermore, due to lack of timely adjustments, defective products are often produced, especially for unattended template sewing machines, which often cause great losses when they are discov...
