DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] See also Figures 1 to 4 The embodiment of the present application provides a high-precision cutting device for cotton yarn processing, including a frame 1, a yarn 101 and a movable plate 2, the frame 1 is rotatably connected with a pay-off roller 3 and a take-up roller 4, the frame 1 is provided with a receiving frame 5, the receiving frame 5 is slidably connected with an L-shaped plate 6, the L-shaped plate 6 is provided with a segmentation blade 7, the segmentation blade 7 is arranged in cooperation with the receiving frame 5, the movable plate 2 and the L-shaped plate 6 are slidably connected through a sliding card mechanism, a plurality of springs 8 are provided at the bottom of the movable plate 2, the bottom ends of the plurality of springs 8 are provided with the same electric heating plate 9, a rotating drive device 10 is provided on the receiving frame 5, a gear 11 is provided at the output end of the rotating drive device 10, a waist-shaped rack 12 is provided on the movable plate 2, the gear 11 is meshedly connected with the waist-shaped rack 12, a waist-shaped receiving groove 13 is provided on the movable plate 2, a circular receiving shaft 14 is provided at the axis of the gear 11, and the circular receiving shaft 14 slides in the waist-shaped receiving groove 13.

[0021] In this embodiment, the yarn 101 is released from the pay-off roller 3, passes through the surface of the receiving frame 5, and is wound around the take-up roller 4. The rotary driving device 10 drives the waist-shaped rack 12 to move through the gear 11. The movement trajectory of the waist-shaped rack 12 and the moving plate 2 is a waist-shaped hole. The circular receiving shaft 14 on the gear 11 supports the moving plate 2 through the waist-shaped receiving groove 13. When the gear 11 drives the moving plate 2 to move downward along the arc part on the waist-shaped hole, the moving plate 2 will drive the L-shaped plate 6 to move up and down through the sliding clamping mechanism, so that the dividing blade 7 on the L-shaped plate 6 can move up and down and cooperate with the receiving frame 5 to divide the yarn 101. When the moving plate 2 descends and moves along the straight part on the waist-shaped hole, the heating plate 9 will be driven by the spring 8 to move horizontally. Before that, when the moving plate 2 descends, the heating plate 9 abuts against the receiving frame 5 before the dividing blade 7. Then, through the contraction of the spring 8, the heating plate 9 and the receiving frame 5 squeeze and fix the yarn 101. Then the dividing blade 7 descends and After the yarn 101 is cut, the heating plate 9 starts to heat and moves along with the straight part of the waist hole in the sliding trajectory of the moving plate 2, thereby twisting and melting the broken end of the yarn 101, making it less likely to break. After the heating plate 9 squeezes and fixes the yarn 101, the moving trajectory of the moving plate 2 is still at the arc of the waist hole. Afterwards, before the moving plate 2 slides to the straight line of the waist hole, the heating plate 9 will produce a certain twisting effect on the squeezed and fixed yarn 101 in advance due to the special shape of the arc of the waist hole, but it will not affect the cutting of the yarn 101 by the cutting blade 7. When the moving plate 2 slides along the track of the waist hole shape, the L-shaped plate 6 is driven downward by the sliding clamping mechanism, and the moving plate 2 will slide on the L-shaped plate 6. After the heating plate 9 abuts against the receiving frame 5 to squeeze and fix the yarn 101 and move and heat it, the spring 8 undergoes a certain deformation, but it will not affect its use and the movement of the heating plate 9.

[0022] In some embodiments, in order to realize the sliding card connection relationship between the movable plate 2 and the L-shaped plate 6, a sliding card connection mechanism is provided, including a fixed plate 15, the fixed plate 15 is installed on the L-shaped plate 6, and a transverse card groove 16 is provided on the fixed plate 15. A card block 17 is installed on the movable plate 2, and the card block 17 slides in the transverse card groove 16.

[0023] In some embodiments, in order to protect the spring 8 , a plurality of telescopic rods 18 are installed at the bottom of the movable plate 2 . The telescopic rods 18 correspond to the springs 8 one by one, and the springs 8 are located inside the telescopic rods 18 .

[0024] In some embodiments, in order to reduce the weight of the rotary drive device 10 and avoid damage thereof, a second spring 19 is installed on the receiving frame 5 , and the bottom of the second spring 19 is connected to the L-shaped plate 6 .

[0025] In some embodiments, in order to facilitate the segmentation of the yarn 101 , a knife groove 20 is provided on the receiving frame 5 , and the knife groove 20 is matched with the segmentation blade 7 .
