Description

Technical Field

[0001] The utility model relates to the technical field of a heddle drawing-in machine, and more specifically to a fast yarn feeding mechanism of an automatic heddle drawing-in machine. Background Art

[0002] A drawing-in machine is a device used in the textile industry to pass yarn through the fabric on the loom. It is commonly used to make various fabrics, such as cotton, wool, silk, etc. The main function of the drawing-in machine is to guide the yarn from one edge to the other and form the fabric on the loom. The yarn guide device is used to guide the path of the yarn and ensure that the yarn passes through the loom in the correct direction. The threading mechanism is responsible for passing the yarn through the shuttle of the fabric and forming the fabric on the loom. The fabric winding device is used to wind up the fabric and complete the entire drawing-in process.

[0003] However, the common yarn feeding mechanism cannot adaptively adjust the tension according to different types of yarns, resulting in the yarn being tight or broken easily if the yarn tension is too large during the yarn feeding process; and the yarn being shaken easily during transmission if the yarn tension is too small. Both too large and too small tensions will affect the quality of the final product. Utility Model Content
