[0027] In the present embodiment, after the warp knitting machine has knitted the yarn into cloth, it is necessary to wind up the cloth. At this time, the end of the cloth needs to be fixed on the winding roller 3. During operation, the first motor 10 is turned on first. Driven by the first motor 10, the first screw rod 11 will rotate, thereby driving the first support column 7 to move, and then driving the vacuum pump 8 to move. During the movement of the vacuum pump 8, the docking head 9 will be driven to move, so that the docking head 9 is docked with the connecting pipe 6 at one end of the winding roller 3. At this time, the vacuum pump 8 is turned on, and the air in the internal cavity 4 of the winding roller 3 is filled with air through the vacuum pump 8. The air is sucked out, thereby generating a lower air pressure in the cavity 4, and at the same time, the outside air enters the cavity 4 through the through hole 5, thereby forming a local low-pressure area near the roller surface of the winding roller 3, and the suction force generated by this low-pressure area is used to firmly adsorb the end of the cloth on the winding roller 3. This design realizes the automatic adsorption and fixation of the end of the cloth, reduces manual intervention and labor intensity, simplifies the preparation work flow before winding, shortens the production cycle and improves the overall production efficiency. After the end of the cloth is fixed on the winding roller 3, the winding roller 3 can be rotated to wind the cloth.

[0028] Further, such as Figure 1 and Figure 3 As shown, grooves 12 are respectively provided at both ends of the top of the mounting frame 2, and the winding roller 3 is movably connected to the groove 12. A second support column 13 is fixedly connected to the end of the base 1 away from the vacuum pump 8, and a second motor 14 is fixedly connected to the top of the second support column 13. The output shaft of the second motor 14 is connected to the winding roller 3 through a coupling 15;

[0029] In this embodiment, the second motor 14 is designed to provide driving force for the rotation of the winding roller 3. The coupling 15 is designed to allow the winding roller 3 to be removed from the output shaft of the second motor 14. The groove 12 is designed to allow the winding roller 3 to be removed from the mounting frame 2, thereby facilitating the replacement of a new winding roller 3 to wind up the fabric.

[0030] Further, such as Figure 1 and Figure 4 As shown, the base 1 is provided with a first slide groove 16 below the second support column 13, a first slider 17 is fixedly connected to the bottom of the second support column 13, and the first slide groove 16 is slidably connected to the first slider 17;

[0031] In this embodiment, the design of the first sliding block 17 and the first sliding groove 16 allows the first supporting column 7 to be smoothly slidably connected to the base 1 .

[0032] Further, such as Figure 1As shown, a U-shaped frame 18 is fixedly connected to one end of the top of the base 1 away from the winding roller 3, and two feeding rollers 19 are rotatably connected to the inner wall of the U-shaped frame 18. A third motor 20 is fixedly connected to one end of the outer wall of the U-shaped frame 18, and the output end of the third motor 20 is fixedly connected to the feeding roller 19;

[0033] In this embodiment, the end of the cloth is placed between two feed rollers 19, and then one of the feed rollers 19 is driven to rotate by the third motor 20, thereby driving the cloth and the other feed roller 19 to rotate, so as to realize the feeding process during the cloth winding process, wherein a gap is left between the two feed rollers 19 to facilitate the passage of the cloth, and when the cloth is located between the two feed rollers 19, the two feed rollers 19 can realize synchronous reverse rotation.

[0034] Further, such as Figure 1 and Figure 5 As shown, the base 1 is located between the winding roller 3 and the feeding roller 19 and is fixedly connected to a support frame 21, a movable plate 22 is slidably connected to the top of the support frame 21, and two cylinders 23 are fixedly connected to the bottom of the movable plate 22, and the output ends of the two cylinders 23 are commonly fixedly connected to a connecting plate 24, and the two ends of the bottom of the connecting plate 24 are respectively fixedly connected to electric telescopic rods 25, and the output ends of the two electric telescopic rods 25 are commonly fixedly connected to a movable plate 26, and the connecting plate 24 and the movable plate 26 are both fixedly connected to a clamping block 27; a fourth motor 30 is fixedly connected to one end of the top of the support frame 21, and a second screw rod 31 is fixedly connected to the output end of the fourth motor 30, and a connecting block 32 is fixedly connected to the top of the movable plate 22, and the second screw rod 31 is threadedly connected to the connecting block 32;

[0035] In this embodiment, when the end of the cloth passes through between the two feeding rollers 19, the fourth motor 30 is turned on, and the second screw rod 31 is driven to rotate by the fourth motor 30, thereby driving the movable plate 22 to move. When the movable plate 22 moves to the adjacent position of the feeding roller 19, the cylinder 23 is opened, so that the two clamping blocks 27 move downward. When the end of the cloth is located between the two clamping blocks 27, the movable plate 26 is driven to move upward by the electric telescopic rod 25, so that the two clamping blocks 27 are closed together, thereby clamping the end of the cloth. At this time, the fourth motor 30 is turned on again, and the movable plate 22 is driven by the fourth motor 30 to move to above the winding roller 3, thereby Drive the clamping block 27 to move above the winding roller 3, so as to pull the end of the cloth above the winding roller 3. At this time, the two clamping blocks 27 can be driven to separate by the electric telescopic rod 25, so as to release the end of the cloth. One end of the cloth will contact the winding roller 3 during the falling process. At this time, the end of the cloth will be adsorbed on the winding roller 3 by the action of the vacuum pump 8, so that the cloth can be rolled up. During operation, in order to allow the end of the cloth to accurately fall onto the winding roller 3, the clamping block 27 can be driven downward by the cylinder 23, so that the end of the cloth is closer to the winding roller 3, and then the end of the cloth can fall onto the winding roller 3 smoothly.

[0036] Further, such as Figure 1 and Figure 5 As shown, the two ends of the movable plate 22 are respectively fixedly connected with second sliders 28, and the two ends of the top of the support frame 21 are respectively provided with second slide grooves 29, and the second sliders 28 are slidably connected with the second slide grooves 29;

[0037] In this embodiment, the second sliding block 28 and the second sliding groove 29 are designed so that the movable plate 22 can be smoothly slidably connected to the supporting frame 21 .

[0038] Further, such as Figure 1 As shown, a connecting ear 33 is fixedly connected to one end of the top of the support frame 21 away from the fourth motor 30, and the connecting ear 33 is rotatably connected to the second screw rod 31;

[0039] In this embodiment, the connecting ear 33 is designed to support the end of the second screw rod 31 away from the fourth motor 30, thereby ensuring the stability of the second screw rod 31 when rotating.

[0040] Working principle: After the warp knitting machine weaves the yarn into cloth, it is necessary to roll up the cloth. The end of the cloth is placed between the two feed rollers 19, and then the third motor 20 drives one of the feed rollers 19 to rotate, thereby driving the cloth and the other feed roller 19 to rotate, so as to realize the transmission of the cloth. When the end of the cloth passes between the two feed rollers 19, the fourth motor 30 is turned on, and the second screw rod 31 is driven to rotate by the fourth motor 30, thereby driving the moving plate 22 to move. When the moving plate 22 moves to the feed roller 19 When the cloth ends are located between the two clamping blocks 27, the movable plate 26 is driven upward by the electric telescopic rod 25, so that the two clamping blocks 27 are closed together, thereby clamping the cloth ends. At this time, the fourth motor 30 is turned on again, and the movable plate 22 is driven by the fourth motor 30 to move to the top of the winding roller 3, thereby driving the clamping block 27 to move to the top of the winding roller 3, so that the cloth ends are pulled to the top of the winding roller 3, and then the electric telescopic rod 25 can be driven to move the movable plate 22 to the top of the winding roller 3. The two clamping blocks 27 are separated to release the end of the cloth. One end of the cloth will contact the winding roller 3 during the falling process. Before releasing the end of the cloth, the first motor 10 is turned on. Driven by the first motor 10, the first screw rod 11 will rotate, thereby driving the first support column 7 to move, and then driving the vacuum pump 8 to move. During the movement of the vacuum pump 8, the docking head 9 will be driven to move, so that the docking head 9 is docked with the connecting pipe 6 at one end of the winding roller 3. At this time, the vacuum pump 8 is turned on to fill the internal cavity of the winding roller 3 with air. The air in the cavity 4 is evacuated, thereby generating a lower air pressure in the cavity 4, and at the same time, the outside air enters the cavity 4 through the through hole 5, thereby forming a local low-pressure area near the roller surface of the winding roller 3, and the suction force generated by this low-pressure area is used to firmly adsorb the end of the cloth on the winding roller 3 during the falling process. In addition, in order to allow the end of the cloth to accurately fall on the winding roller 3, the clamping block 27 can be driven downward by the cylinder 23, so that the end of the cloth is closer to the winding roller 3, and then the end of the cloth can smoothly fall on the winding roller 3.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
