Description

Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a clothing repairing sewing machine with a thread-breaking prevention structure. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper. The stitches are neat, beautiful, flat, and firm, and the sewing speed is fast and easy to use. Art forms such as hand-push embroidery and computer embroidery have been derived from it. At present, with the continuous development of science and technology, the use of sewing machines has become more and more widespread. However, when general sewing machines are working, the device cannot dissipate heat well, which leads to the phenomenon of thread breakage, thus affecting the use effect.

[0003] The existing clothing repair sewing machine usually has a chassis that cannot dissipate heat well, and cannot provide power to the take-up roller during operation, which makes the thread break easily. Therefore, we propose a clothing repair sewing machine with an anti-thread break structure. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing equipment that the chassis usually cannot dissipate heat well and cannot provide power for the take-up roller during operation, resulting in easy thread breakage, and to propose a clothing repair sewing machine with an anti-thread breakage structure.

[0011] Preferably, a worm is fixedly sleeved on the second transmission rod, a worm wheel is fixedly sleeved on the third transmission rod, and the worm is meshingly connected with the worm wheel.

[0012] Preferably, the second transmission rod and the third transmission rod are both rotatably connected to the same protection box, a support frame is fixedly mounted on the bottom of the base, and a universal wheel is fixedly mounted on the bottom of the support frame.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] (1) In this scheme, since a first transmission rod and a wire feeding roller are provided, the output shaft of the motor drives the first transmission rod to rotate, the first transmission rod drives the wire feeding roller to rotate, and the wire feeding roller drives the wire taking-up roller to rotate, so that the wire on the wire taking-up roller can be unwound, avoiding the wire being subjected to excessive force.
