A sewing machine with convenient installation of thread gripper

Abstract

The invention relates to the technical field of sewing machines, in particular to a sewing machine with a thread tensioner which is easy to install, comprising a workbench, a machine head and a thread tensioner, the machine head is fixedly arranged at one end of the upper surface of the workbench, and There is a first threaded hole on the side, and a thread clamp installation cylinder is arranged in the first thread hole, and the outer surface of the thread clamp installation cylinder is provided with an external thread that matches the first thread hole. Limit slots are provided on the upper surface of the device mounting cylinder; during the disassembly or installation process of the thread tensioner on the sewing machine of the present invention, the thread tensioner only needs to be pushed inward or outward to realize the disassembly of the thread tensioner Or installation, its operation is extremely convenient, no need to open the cover of the machine head, and then use a screwdriver to tighten it, which brings great convenience to the operator, reduces the downtime caused by maintenance and replacement of the tensioner, and effectively improves The efficiency of the sewing machine.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine with a thread tensioner which is easy to install. Background technique [0002] Sewing machine is a common fabric processing equipment, which is mainly composed of a few parts such as workbench, body, machine head and so on. A thread clamp is installed on the machine head of the sewing machine, which mainly clamps the suture when sewing, and gives the suture an appropriate clamping force. When the clamping force is too large, the tension on the suture will be too large when the needle guides the sewing thread to sew, and it is easy to break the thread. If the clamping force is too small, the tension on the suture will If it is too small, it will affect the stitch quality. At present, the thread tensioner on the machine head of the existing sewing machine is fixed on the machine head by screws or bolts. When the thread tensioner breaks down, it is necess...

AI Technical Summary

Problems solved by technology

When the clamping force is too large, the tension on the suture will be too large when the needle guides the sewing thread to sew, and it is easy to break the thread. If the clamping force is too small, the tension on the suture will If it is too small, it will affect the quality of stitches

At present, the thread tensioner on the machine head of the existing sewing machine is fixed on the machine head by screws or bolts. When the thread tensioner breaks down, it is necessary to open the cover on the machine head and use a screwdriver to remove the thread tensioner from the machine head. Take it off for maintenance and replacement, which brings great inconvenience to the operators

[0003] The utility model with the patent No. CN209428721U discloses a new type of household sewing machine panel thread tensioner, which includes a connecting rod. The surface of the connecting rod is provided with evenly distributed six-thread threads. One end of the connecting rod and the threaded hole provided in the middle of the rotary button Threaded connection, the other end of the connecting rod is interspersed with the through holes opened in the middle of the two clamping discs, and the surface of the connecting rod is covered with a first spring; the thread clamping device is installed on the head of the sewing machine, by turning the bolt It can only be fixed on the through hole, so when the thread tensioner is damaged and needs to be repaired or replaced, the steps are cumbersome

Therefore, for the inconvenient installation of the thread clamp on the existing sewing machine, it is a technical problem to be solved to design a sewing machine that can quickly and easily install the thread clamp
