[0012] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0013] Example 1:

[0014] As Figure 1 , Figure 2 , Figure 3As shown, this utility model discloses a warp knitting machine winding and cutting device, including a base plate 1 and a winding frame 2 disposed at one end of the base plate 1. A winding roller 3 is disposed on the winding frame 2. A column 4 is disposed on the base plate 1 at the other end relative to the winding frame 2, and a guide roller 5 is disposed on the column 4. A top frame 6 is disposed on the top of the winding frame 2 and the column 4. A vertical lifting mechanism is disposed on the base plate 1 between the guide roller 5 and the winding roller 3. A support plate 7 is disposed on the vertical lifting mechanism. A groove 8 is disposed in the middle of the support plate 7. The length direction of the groove 8 is consistent with the circumferential direction of the winding roller 3. Above the groove 8... A first vertical guide post 9 is provided on the top frame 6, and the first guide post 9 is slidably connected to the top frame 6. A horizontal guide rail 11 is fixed at the lower end of the first guide post 9. A sliding frame 12 is provided on the horizontal guide rail 11, and a cutting blade 20 is fixed on the sliding frame 12. The vertical downward projection of the cutting blade 20 is located within the groove 8. A power mechanism is provided on the sliding frame 12, and the power mechanism drives the sliding frame 12 to move on the horizontal guide rail 11. The length direction of the horizontal guide rail 11 is consistent with the length direction of the groove 8. A first electric push rod 10 is provided between the horizontal guide rail 11 and the top frame 6.

[0015] The fabric produced by the warp knitting machine is conveyed to the winding roller 3 via the guide roller 5 for winding. After the winding roller 3 has wound a certain diameter, the fabric needs to be cut, and the winding roller 3 is replaced for rewinding. When winding is complete, the winding roller 3 stops running, and the fabric remains stationary. The vertical lifting mechanism drives the support plate 7 to move upward until it is in contact with the fabric. Since the wound fabric is under a certain tension, when the first electric push rod 10 drives the horizontal guide rail 11 to move downward, the cutting blade 20 moves downward and contacts the fabric. Then, the sliding frame 12 moves on the horizontal guide rail 11 under the action of the power mechanism, thus realizing the cutting of the fabric. The process is fast and accurate, with a clean cut and high efficiency.

[0016] The power mechanism is as follows: a vertically downward motor 18 is installed on the sliding frame 12, and a rubber roller 19 is installed on the output shaft of the motor 18. The rubber roller 19 is pressed against the side wall of the horizontal guide rail 11. The sliding frame 12 is freely slidably connected to the horizontal guide rail 11. The motor 18 is installed on the sliding frame 12, and the rubber roller 19 is installed on the output shaft of the motor 18. The motor 18 drives the rubber roller 19 to rotate. Since the rubber roller 19 is in contact with the side wall of the horizontal guide rail 11, the rotation of the rubber roller 19 can drive the sliding frame 12 to move on the horizontal guide rail 11.

[0017] In other embodiments, the power mechanism comprises: a vertically downward-facing electric motor 18 mounted on the sliding frame 12; a gear mounted on the output shaft of the electric motor 18; and a horizontal rack mounted on the side wall of the horizontal guide rail 11, with the horizontal rack engaging with the gear. This solution uses the same principle as the aforementioned power mechanism, replacing the rubber roller 19 with a gear and installing a horizontal rack on the horizontal guide rail 11. The engagement of the gear and the horizontal rack results in higher operational stability.

[0018] A vertically downward second guide post 14 is provided on the top frame 6 corresponding to the support plate 7 on one or both sides of the groove 8. A pressure plate 13 is provided at the lower end of the second guide post 14 on the same side of the groove 8. A second electric push rod 15 is provided between the pressure plate 13 and the top frame 6. Preferably, pressure plates 13 can be provided at the corresponding positions of the support plates 7 on both sides of the groove 8. During actual cutting, the support plate 7 moves upward to fit against the fabric, while the upper pressure plate 13 moves downward under the action of the second electric push rod 15, pressing it against the fabric. Therefore, the fabric is pressed between the support plate 7 and the pressure plate 13, while the area corresponding to the groove 8 is exposed. The horizontal guide rail 11 moves downward under the action of the first electric push rod 10, and in conjunction with the action of the motor 18, moves the cutting blade 20 to cut the clamped fabric, resulting in a better cutting effect. Simultaneously, after cutting, the pressure plate 13 still clamps both ends of the fabric. The operator can glue the end closest to the winding roller 3 to the winding roller 3 to ensure the stability of the fabric on the winding roller 3. Then, the winding roller 3 is replaced. After replacing the winding roller 3, the operator can stretch the end of the other fabric onto the winding roller 3 for fixation to ensure stable winding. The winding roller 3 replacement process is faster and more efficient, improving processing efficiency.

[0019] The vertical lifting mechanism includes multiple third guide columns 16 mounted on the base plate 1. The third guide columns 16 are sleeve structures. The support plate 7 is fixed on the third guide columns 16. A third electric push rod 17 is provided between the support plate 7 and the base plate 1.

[0020] Since the base plate 1 is fixed to the ground, in order to ensure that the support plate 7 can be raised and lowered stably on the third guide column 16, the third guide column 16 is adopted as a sleeve structure. During the stable raising and lowering process, neither end of the third guide column 16 needs to exceed the base plate 1 and the support plate 7, and the support plate 7 can be raised and lowered along the third guide column 16, which is stable and reliable.
