Description

Technical Field

[0001] The utility model belongs to the technical field of clothing processing, in particular to a sewing machine with thread end processing function. Background Art

[0002] Sewing machines are needed in the process of clothing processing. Sewing machines are machines that use 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. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, and products such as leather, plastic, and paper. The stitches are neat, beautiful, flat, and firm, with fast sewing speed and easy use. During use, the sewing machine needs to cut off the excess thread ends. If the thread ends are not handled in time after cutting, it will affect subsequent processing.

[0003] A Chinese patent with application number CN202222564010.0 discloses a sewing machine that can absorb fallen thread ends, which belongs to the field of clothing processing technology. The sewing machine body includes a sewing machine body, on which a thread end collecting mechanism and a cloth carrying mechanism are provided. The thread end collecting mechanism includes a mounting plate installed on the sewing machine body, and a collecting fan and a collecting cylinder are fixed on the side of the mounting plate. The air inlet of the collecting fan is connected to a conveying pipe, and the other end of the conveying pipe is connected to an extraction hood installed on the sewing machine body, and the air outlet of the collecting fan is connected to the collecting cylinder.

[0004] The above scheme sets up a thread collection mechanism, uses a collection fan in conjunction with a collection barrel, draws the thread ends cut during the sewing process into the collection barrel through an extraction hood, and uses a breathable filter to achieve a good filtering and collection effect. However, in actual use, the thread ends drawn into the collection barrel by the collection fan will accumulate on the surface of the breathable filter under the influence of air circulation. When a large amount of thread ends accumulates, the ventilation effect of the filter will be affected and need to be cleaned in time. The above scheme realizes the processing of the thread ends in the collection barrel by removing the fixing bolts on the breathable filter. When cleaning the thread ends, the collection fan needs to be shut down, resulting in reduced processing efficiency.

[0005] In view of this, the present utility model is proposed. Utility Model Content
