DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A positioning and wire-breaking mechanism for coated yarn production in this embodiment includes a fixed plate 1, a transmission component and a shearing component are arranged on the fixed plate 1, a control panel 2 is installed on the fixed plate 1, and the fixed plate 1 is an "L"-shaped plate.

[0024] The transmission assembly includes a mounting frame 12 and a driving motor 13. The driving motor 13 is fixed on the mounting frame 12. The mounting frame 12 is fixedly mounted on the side wall of the fixed plate 1. A second rotating rod is fixedly connected to the output shaft of the driving motor 13. The second rotating rod penetrates the fixed plate 1 and is fixed with an upper guide wheel 3. A driving gear 14 is fixedly mounted on the outside of the second rotating rod. A first rotating rod 18 is rotatably connected to the inside of the fixed plate 1. A stabilizing plate rotatably connected to the first rotating rod 18 is fixed on the side wall of the fixed plate 1. A driven gear 17 is fixedly mounted on the outside of the first rotating rod 18. The driven gear 17 is meshed with the driving gear 14. A lower guide wheel 4 is fixedly connected to one side of the first rotating rod 18. An annular plate 15 is fixedly connected to the outside of the upper guide wheel 3. A resistance increasing strip is fixedly mounted on the outer wall of the annular plate 15. An annular groove 16 is provided on the outer wall of the lower guide wheel 4. One side of the annular plate 15 is located inside the annular groove 16.

[0025] The yarn pressed between the annular groove 16 and the annular plate 15 has a certain positioning effect, so that the moving yarn is not easily displaced.

[0026] It should be noted that a fixing rod 11 is fixedly connected between the wire tube 6 and the fixing plate 1 , and the wire tube 6 is in an inclined state, with the left side higher than the right side, so that the yarn cut in the wire tube 6 can slide out of the wire tube 6 by itself.

[0027] The cutting assembly includes a wire tube 6, which is installed on a fixed plate 1. A second fixed plate 8 is fixedly connected to the outer wall of the wire tube 6. An electric push rod 7 is fixed to the side of the second fixed plate 8 away from the wire tube 6. A cutting head 9 is fixedly connected to the telescopic end of the electric push rod 7.

[0028] It should be noted that the electric push rod 7 and the driving motor 13 are both electrically connected to the control panel 2. By driving the driving motor 13 to drive the driving gear 14 to rotate, the upper guide wheel 3 and the lower guide wheel 4 can be rotated relative to each other, thereby driving the yarn to move.

[0029] See also Figure 3 A wire assembly 5 is provided on the side of the wire tube 6 close to the upper guide wheel 3, and the wire assembly 5 includes a U-shaped plate 51, and an L-shaped rod 52 is fixedly connected to the bottom of the U-shaped plate 51. The L-shaped rod 52 is fixedly connected to the side of the wire tube 6 close to the upper guide wheel 3, and a wire wheel 53 is rotatably connected inside the U-shaped plate 51.

[0030] The wire assembly 5 is provided to guide the yarn, thereby preventing the yarn from rubbing against the end of the wire tube 6 during movement.

[0031] In this embodiment, the inner top wall of the wire tube 6 is fixedly connected to a support seat 10, and an arc groove is provided on the side of the support seat 10 close to the cutting head 9. The side of the cutting head 9 close to the support seat 10 is an arc structure, and an opening is provided on one side of the wire tube 6, and the cutting head 9 extends through the opening to the interior of the wire tube 6.

[0032] The arc surface of the cutting head 9 is matched with the arc groove, so that the yarn on the support seat 10 can be cut by the cutting head 9 moving and pressing on the support seat 10.

[0033] The working principle of the above embodiment is as follows: when in use, the upper guide wheel 3 and the driving gear 14 can be rotated counterclockwise by driving the second rotating rod 13 to rotate, and at the same time, the driven gear 17 can be driven to rotate, so that the lower guide wheel 4 can be rotated clockwise, so that the yarn passing through the annular groove 16 and pressed on the bottom of the annular plate 15 can move under the rotation of the annular plate 15. When the yarn needs to be cut, the driving motor 13 is turned off to stop moving the sand line, and then the electric push rod 7 is used to push the cutting head 9 to move and cut the yarn in contact with the support seat 10. The cut yarn will slide out of the wire tube 6, and then the relatively rotating upper guide wheel 3 and lower guide wheel 4 can drive the yarn to move to perform the next cutting, without pulling the yarn head over the cutting head 9.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
