[0031] Reference below Figures 1 to 6 To describe the yarn cloth and yarn cutting device according to an embodiment of the present utility model.

[0032] According to the embodiment of the present invention, the yarn cloth and yarn cutting device includes a base plate 110, a rotating part 200, a first pressing roller 300, a yarn picking roller 400 and a cutter 810. The base plate 110 is arranged longitudinally; the rotating part 200 is rotatably connected to the side wall of the base plate 110 and can rotate relative to the base plate 110; the first pressing roller 300 is connected to the rotating part 200, and the rotating part 200 rotates relative to the base plate 110 so that the first pressing roller 300 swings up and down; the yarn picking roller 400 is located above the first pressing roller 300 and is rotatably connected to the rotating part 200. The yarn picking roller 400 rotates relative to the rotating part 200 so that the yarn picking roller 400 swings left and right; the cutter 810 is connected to the base plate 110 and is arranged behind the yarn picking roller 400. The cutter 810 is driven by the driving mechanism to cut the first pressing roller 300 and the bottom of the yarn picking roller 400.

[0033] For example Figure 3 、 Figure 4 and Figure 5 As shown, the rotating portion 200 is connected to the side wall of the base plate 110 and can rotate relative to the base plate 110. The first pressing roller 300 and the yarn picking roller 400 are both arranged on the rotating portion 200. When the rotating portion 200 rotates relative to the base plate 110, the first pressing roller 300 and the yarn picking roller 400 can be driven to swing up and down.

[0034] There are various ways to drive the rotating portion 200 to rotate relative to the base plate 110, including driving the rotating portion 200 to rotate by rotating a driving motor, or driving the rotating portion 200 to rotate by a piston.

[0035] Furthermore, the yarn pick-up roller 400 can rotate relative to the rotating portion 200, thereby being able to swing left and right. There are also various ways to drive the yarn pick-up roller 400 to rotate relative to the rotating portion 200, including driving the yarn pick-up roller 400 by rotating a driving motor, or driving the yarn pick-up roller 400 by a piston.

[0036] The cutter 810 is connected to the base plate 110 and is arranged behind the yarn picking roller 400, for example Figure 5 When the yarn spreading and shearing device has finished spreading the yarn, the drive mechanism drives the cutter 810 to cut the fibers and directly cut the fibers, thereby completing the yarn shearing work.

[0037] For example Figure 6 As shown, the specific operating steps of the yarn cloth and yarn cutting device are as follows: after the fiber comes out of the yarn discharge device, passes under the first yarn pressing roller 300 and reaches the yarn cloth roller 700, the yarn pick-up roller 400 rotates relative to the rotating part 200 to leave the top of the first yarn pressing roller 300. The rotating part 200 rotates so that the first yarn pressing roller 300 and the yarn pick-up roller 400 swing downward at the same time, so that the fiber is located below the first yarn pressing roller 300, and a height difference is formed between the yarn cloth roller 700 and the first yarn pressing roller 300. At this time, the yarn pick-up roller 400 swings again and swings under the fiber. At this time, the rotating part 200 swings back, so that the yarn pick-up roller 400 picks up the fiber, thereby facilitating the yarn cloth device to place the fiber on the yarn cloth roller 700. After the fiber is wound on the yarn cloth roller 700, the yarn discharge device reverses to apply tension to the fiber, so that the fiber is in a taut state. At this time, the driving mechanism drives the cutter 810 to cut the fiber, thereby cutting the fiber.

[0038] The yarn spreading and cutting device according to the embodiment of the present invention is more intelligent and can automatically complete the operations of yarn picking, yarn spreading and yarn cutting, wind the fibers on the yarn spreading roller 700 and automatically cut the fibers after the fiber winding is completed.

[0039] In some specific embodiments of the present invention, a guide plate 820 and a fourth piston 640 are further included. The guide plate 820 is connected to the base plate 110. The fourth piston 640 is arranged on the guide plate 820. The fourth piston rod 641 of the fourth piston 640 is connected to the cutter 810 to drive the cutter 810 to move.

[0040] For example Figure 3 and Figure 5 As shown, the yarn cloth and shearing device also includes a guide plate 820 and a fourth piston 640, and the guide plate 820 is obliquely arranged and connected to the base plate 110. The orientation of the guide plate 820 enables the cutter 810 to be stably aligned with the bottom of the yarn picking roller 400 and the yarn pressing roller, thereby facilitating the cutting of the fibers.

[0041] The fourth piston 640 is disposed on the guide plate 820 . The fourth piston rod 641 of the fourth piston 640 is connected to the cutter 810 . The fourth piston rod 641 is retracted so that the cutter 810 can cut the fibers and cut the fibers.

[0042] In some specific embodiments of the present invention, a fifth piston 650 and a second pressing roller 310 are also included. The fourth piston 640 is arranged on the side of the guide plate 820 facing the first pressing roller 300 and the picking roller 400, and the fifth piston 650 is arranged on the side of the guide plate 820 facing away from the first pressing roller 300 and the picking roller 400; the second pressing roller 310 is arranged opposite to the first pressing roller 300, and the fifth piston rod 651 of the fifth piston 650 is connected to the second pressing roller 310 to drive the second pressing roller 310 to move.

[0043] For example Figure 3 and Figure 5 As shown, the yarn cloth and shearing device also includes a fifth piston 650 and a second pressing roller 310. The fourth piston 640 is located on the side of the guide plate 820 facing the first pressing roller 300 and the yarn pick-up roller 400, facilitating the movement of the cutter 810 to cut the fibers. The second pressing roller 310 is positioned opposite the first pressing roller 300, thereby providing a pressing roller on both sides of the cloth roller 700 for better yarn pressing.

[0044] The fifth piston 650 is disposed on a side of the guide plate 820 facing away from the first pressing roller 300 and the yarn pick-up roller 400. The fifth piston rod 651 of the fifth piston 650 is connected to the second pressing roller 310, driving the second pressing roller 310 to move closer to or away from the cloth roller 700. The arrangement of the fifth piston 650 and the fifth piston rod 651 allows the position of the second pressing roller 310 to be adjusted, thereby facilitating the gradual adjustment of the distance between the second pressing roller 310 and the cloth roller 700 as the yarn is being fed. As the thickness of the yarn layer on the cloth roller 700 increases, the second pressing roller 310 gradually moves away from the cloth roller 700, thereby maintaining a constant distance between the second pressing roller 310 and the cloth roller 700, thereby achieving the best yarn pressing effect.

[0045] In some specific embodiments of the present invention, an anvil 500 and a connecting plate 510 are also included. One end of the connecting plate 510 is connected to the side wall of the base plate 110. The anvil 500 is arranged above the yarn picking roller 400 and is rotatably connected to the bottom of the connecting plate 510 so that it can swing left and right.

[0046] For example Figure 3 and Figure 4 As shown, the yarn cloth and shearing device further includes an anvil 500 and a connecting plate 510. The connecting plate 510 is arranged longitudinally, and one end is connected to the side wall of the base plate 110, so that the connecting plate 510 and the base plate 110 are arranged in a T-shape. A hole is opened at the bottom of the connecting plate 510, and the top of the anvil 500 is connected to the hole at the bottom of the connecting plate 510 by a hinge, so that it can rotate relative to the connecting plate 510 to achieve left and right swing.

[0047] The anvil 500 can swing left and right, so as to adapt to the yarn picking roller 400, so that there is no gap between the anvil 500 and the yarn picking roller 400, the fibers can be clamped more firmly, and the air between the fibers can be removed, so that the fibers can be firmly stuck together.

[0048] Furthermore, the bottom of the anvil 500 is made of elastic material, which makes the anvil 500 more adaptable and enables the yarn picking roller 400 to be sunken into the elastic material at the bottom of the anvil 500 so that there is no gap between the anvil 500 and the yarn picking roller 400.

[0049] In some specific embodiments of the present invention, a first piston 610 and a first rotating plate 612 are further included. The first piston 610 is arranged on the base plate 110. One end of the first rotating plate 612 is connected to the first piston rod 611 of the first piston 610, and the other end is connected to the rotating shaft of the rotating part 200. The first piston rod 611 is extended and retracted so that the first rotating plate 612 drives the rotating part 200 to rotate.

[0050] For example Figure 3 and Figure 4As shown, the rotary unit 200 further includes a first piston 610 and a first rotating plate 612. The first piston 610 is fixedly mounted on the base plate 110, and the rotating unit 200 is rotatably mounted on the base plate 110. One end of the first rotating plate 612 is connected to the first piston rod 611 of the first piston 610, and the other end is connected to the rotating shaft of the rotating unit 200. The first piston rod 611 extends and retracts, thereby driving the first rotating plate 612 to rotate the rotating unit 200, thereby achieving clockwise or counterclockwise rotation of the rotating unit 200. The clockwise or counterclockwise rotation of the rotating unit 200 drives the first pressing roller 300 and the yarn picking roller 400 to swing up and down.

[0051] In some specific embodiments of the present invention, a second piston 620 and a second rotating plate are also included. The second piston 620 is arranged on the rotating part 200. One end of the second rotating plate is connected to the second piston rod 621 of the second piston 620, and the other end is connected to the yarn picking roller 400. The second piston rod 621 is extended and retracted so that the second rotating plate drives the yarn picking roller 400 to swing left and right.

[0052] For example Figure 3 As shown, the second piston 620 and a second rotating plate are also included. The second piston 620 is fixedly mounted on the rotating portion 200. One end of the second rotating plate is connected to the second piston rod 621 of the second piston 620, and the other end is connected to the yarn pick-up roller 400. The second piston rod 621 of the second piston 620 is extended and retracted, thereby driving the yarn pick-up roller 400 to swing left and right via the second rotating plate, so that the yarn pick-up roller 400 can go under the fiber and pick up the fiber.

[0053] In some specific embodiments of the present invention, a rotating rod 410 and a connecting arm 420 are further included. A rotating hole is provided on the rotating portion 200. One end of the connecting arm 420 is connected to the yarn picking roller 400, and the other end is connected to the rotating rod 410.

[0054] For example Figure 3 As shown, the rotary rod 410 and the connecting arm 420 are further included. The yarn pick-up roller 400 is connected to the connecting arm 420, and the connecting arm 420 is connected to the rotary rod 410. The rotary rod 410 is disposed in a rotating hole on the rotating portion 200, thereby fixing the position of the rotary rod 410. The second piston rod 621 pushes the second connecting plate 510, thereby driving the rotary rod 410, the connecting arm 420, and the yarn pick-up roller 400 to swing together, so that the yarn pick-up roller 400 can pick up fibers.

[0055] In some specific embodiments of the present invention, a movable plate 120 is further included. The movable plate 120 is longitudinally arranged. The movable plate 120 is provided with a slide rail 121 along the longitudinal direction. The base plate 110 is slidably arranged on the slide rail 121 .

[0056] For example Figure 1 and Figure 2 As shown, it also includes a movable plate 120, which is arranged longitudinally. The movable plate 120 is provided with two slide rails 121 along the longitudinal direction.

[0057] In some specific embodiments of the present invention, a plurality of the base plate 110 , the rotating portion 200 , the first pressing roller 300 and the yarn picking roller 400 are provided along the longitudinal direction of the movable plate 120 .

[0058] For example Figure 1 and Figure 2 As shown, four base plates 110, rotating parts 200, first pressing rollers 300 and yarn picking rollers 400 are arranged along the longitudinal direction of the movable plate 120, thereby greatly improving the yarn spreading efficiency of the yarn spreading and shearing device, which is four times the efficiency of setting a single base plate 110, rotating part 200, first pressing roller 300 and yarn picking roller 400, and the yarn spreading operation can be performed on four yarn spreading rollers 700 at the same time.

[0059] In some specific embodiments of the present invention, a third piston 630 is further included. The third piston 630 is disposed on the movable plate 120 .
