Description

Technical Field

[0001] The utility model relates to the technical field of edge trimming machines, in particular to an edge trimming mechanism for producing and processing knitted fabrics. Background Art

[0002] The trimming machine is a device that processes both sides of the cloth. It is mainly used to cut off the rough edges on both sides of the cloth to make the cloth more regular.

[0003] The patent document with the prior art publication number CN216269316U provides a trimming mechanism for knitted fabric production and processing, including a frame, a cloth output frame, a transmission roller, an adjustable tool, a gathering box, a cloth guide roller, a pressure strip, and a first motor. The adjustable tool is optimally set, and the distance of the movable ring is adjusted by using a distance adjusting rod, a fixed hole and a first screw rod to adjust the distance of the tool, thereby adjusting the tool position. At the same time, the second screw rod, a spring and a connecting rod are used to adjust the longitudinal distance of the tool so that it can adapt to different cloth thicknesses, which greatly increases the practicality of the trimming mechanism; the gathering box is optimally set, and the knitted fabric edge material is evenly gathered by the gathering roller, a bidirectional screw and an edge material guide wheel, thereby avoiding the hidden dangers caused by the accumulation of fabric edge materials and replacing the manual gathering of fabric edge materials to improve production efficiency.

[0004] However, during the use of the existing trimming mechanism for knitted fabric production and processing, due to the different widths of the fabric and the different trimming widths, when the mechanism needs to be adjusted, the staff needs to manually adjust the trimming machine to adjust it properly, resulting in poor flexibility of the trimming mechanism. In addition, during the trimming process, due to the weaving of the knitted fabric, the knitted fabric is prone to broken lines at the trimming point after trimming. For this reason, we propose a trimming mechanism for knitted fabric production and processing. Utility Model Content
