Description

Technical Field

[0001] The utility model relates to the technical field of coiling devices, in particular to a coiling device for a textile warp knitting machine. Background Art

[0002] The woven fabric after warp knitting needs to be coiled and stored. Most of the existing coiling devices adopt a structure similar to a new coiling device for a textile warp knitting machine disclosed in the patent document CN213864651U. During the coiling process, since the diameter of the coiling tube gradually increases, the coiling linear speed gradually increases, resulting in an increasing tension on the fabric during coiling. To overcome this problem, in the prior art, usually two parallel and co-rotating rollers in the same direction are adopted, and then the coiling tube is placed thereon, and then the coiling tube is driven to rotate by the two rollers in the same direction at the same speed to achieve coiling. During this process, the coiling speed on the outer circumferential surface of the coiling tube is always consistent, and the tension of the fabric remains unchanged all the time, achieving good results. However, in practice, there are still some obvious defects. Since the coiling tube is relatively thin, the distance between the two rollers cannot be too large. As a result, when the coiling tube becomes thicker and thicker, the coiling tube is easily disengaged from between the two rollers, causing the fabric to fall off.

[0003] Now a coiling device for a textile warp knitting machine is provided, which can always maintain a large contact area with the coiling tube, can provide sufficient support for the coiling tube, and can effectively prevent the coiling tube from disengaging and falling off. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a coiling device for a textile warp knitting machine, effectively solving the problem that the existing coiling tube is easily disengaged from between the two rollers during the coiling process.

[0005] The technical solution it adopts is that it includes a frame, and there are two symmetrically arranged rotating units on the frame. The rotating unit includes two rollers arranged in the front-rear direction, and at least one of the two rollers can rotate actively. A belt is wound around the two rollers, there are small plates on the front and rear sides of the belt, the end of the roller is rotatably connected to the small plate, the end of the small plate far from the center of the frame is hinged to the frame, and a telescopic unit is hinged to the end of the small plate close to the center of the frame. The lower end of the telescopic unit inclines towards the side away from the center of the frame and is hinged to the frame; the rotation of the telescopic unit can drive the small plate to rotate.

[0006] Further, the telescopic unit is an electric cylinder or a hydraulic cylinder.

[0007] Further, there is a motor in the rotating unit, the motor is fixed on the frame, and the motor can drive the roller to rotate.

[0008] The structure of the utility model is ingenious, which can always maintain a large contact area with the coiling tube, provide sufficient support for the coiling tube, and effectively prevent the coiling tube from jumping off and falling. Description of the Drawings

[0010] Figure 2 This is the front cross-sectional view of the utility model.

[0011] Figure 3 This is the top cross-sectional view of the utility model. Detailed Description of the Preferred Embodiment

[0012] The following further elaborates on the detailed implementation of the utility model in conjunction with the drawings.

[0013] As shown by Figures 1 to 3 , the utility model includes a frame 1, and there are two rotation units symmetrically arranged left and right on the frame 1. The rotation unit includes two rollers 2 arranged in the front-rear direction. At least one of the two rollers 2 can rotate actively. A belt 3 is wound around the two rollers 2. There are small plates 4 on the front and rear sides of the belt 3. The ends of the rollers 2 are rotatably connected to the small plates 4. One end of the small plate 4 far from the center of the frame 1 is hinged to the frame 1, and one end of the small plate 4 close to the center of the frame 1 is hinged with a telescopic unit 5. The lower end of the telescopic unit 5 inclines towards the side away from the center of the frame 1 and is hinged to the frame 1; the rotation of the telescopic unit 5 can drive the rotation of the small plate 4.

[0014] The telescopic unit 5 is an electric cylinder or a hydraulic cylinder.

[0015] There is a motor 6 in the rotation unit. The motor 6 is fixed on the frame 1, and the motor 6 can drive the rotation of the roller 2.

[0016] It should be noted that in the front view perspective, the height of the roller close to the center of the frame 1 in the rotation unit cannot be higher than the height of the other roller 2.

[0017] During use, in the initial state, as shown in Figure 1 , 2 , 3, the coiling tube is placed between the two rotation units. The rotation of the motor 6 can drive the belts 3 on the two rotation units to rotate at the same speed, thereby making the coiling tube rotate; as time goes by, more and more fabrics are wound on the coiling tube, and the diameter of the coiling tube becomes larger and larger. At this time, in order to prevent the coiling tube from jumping off and falling, the telescopic unit 5 is started at this time so that the telescopic unit 5 shortens, and one end of the small plate 4 close to the center of the frame 1 descends. The coiling tube is lifted by the belts 3 on the two rotation units, and the contact area between the two is larger, so that finally the coiling tube is not easy to jump off.

[0018] Of course, it can also be concluded from the above that this solution is not only applicable to relatively thin coiled pipes, but also applicable to relatively thick coiled pipes, with strong adaptability. Compared with the traditional coiling structure, the performance of this solution is safer and more reliable.

[0019] The structure of the present utility model is ingenious, capable of maintaining a large contact area with the coiled pipe all the time, providing sufficient support for the coiled pipe, and effectively preventing the coiled pipe from jumping off and falling.
