A sewing machine with automatic thread trimming function

Abstract

The invention belongs to the technical field of sewing, in particular to a sewing machine with automatic thread trimming function, comprising a supporting unit, a thread trimming unit and a sewing unit; the supporting unit includes a table body, a supporting rod and a supporting frame; The manufacturing unit includes a sewing machine head and sewing needles; the upper surface of the table body is fixedly connected with a support rod on the right side; the upper surface of the support rod is fixedly connected with the support frame; the end of the support frame away from the support rod is fixed with the sewing machine head; The sewing machine head is slidably connected to the sewing needle and thread; thus the automatic cutting of the sewing thread is realized, thereby reducing the use of manpower, speeding up the sewing efficiency, avoiding the direct contact between the operator and the cutting edge, and avoiding the operator's injury caused by the operation error. The waste fabric accumulated on the table should be cleaned up in time, so as to avoid the accumulation of waste fabric on the table top of the sewing machine during sewing, which will affect the sewing efficiency. Efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of sewing, in particular to a sewing machine with automatic thread trimming function. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material; the sewing machine can sew cotton, linen, silk, wool , man-made fibers and other fabrics and leather, plastic, paper and other products, the stitches sewn are neat and beautiful, flat and firm, fast sewing speed and easy to use. And derived from it, hand-pushed embroidery computer embroidery and other art forms. However, the traditional sewing machine manually cuts the sewing thread after sewing, so that the length of the sewing thread on the needle is not appropriate, which causes the need to re-thread the thread when sewing again, which reduces the sewing efficiency. When sewing fabrics, it is easy to cause some pro...

Problems solved by technology

[0003] In order to make up for the deficiencies in the prior art, the operator is easily injured by manual thread trimming. Manual thread trimming causes the sewing thread on the needle to be cut in different lengths, which easily makes the sewing thread on the needle off the thread, and waste is accumulated on the sewing machine. Cloth cannot be cleaned and crushed in time to affect the sewing efficiency, and the waste cloth crushing blade is easy to entangle the thread. This invention proposes a sewing machine with automatic thread trimming function.
