However, during the cloth rolling process, as the cloth roll diameter on the surface of the winding roller increases, the linear speed of the winding roller increases, so that the number of cloth rolled per unit time increases, which is likely to cause the cloth to break, and after the winding is completed, the device is likely to cause the cloth on the surface of the winding roller to become loose, affecting the winding effect. To this end, we propose a large circular knitting machine pulling and winding mechanism. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0021] like Figure 1-4 As shown, the utility model is a pulling and winding mechanism of a large circular machine, comprising a base plate 1, two brackets 11 are arranged above the base plate 1, a motor 2 is fixedly arranged on the bracket 11 on one side, a rotating rod 21 is arranged at the output end of the motor 2, a driving wheel 22 is fixedly sleeved on the rotating rod 21, a belt 23 is arranged outside the driving wheel 22, and a driven wheel 24 is sleeved at the other end of the belt 23. By turning on the switch of the motor 2, the rotating rod 21 at the output end of the motor 2 starts to rotate, and the rotation of the rotating rod 21 can rotate the driving wheel 22 sleeved outside it, and the rotation of the driving wheel 22 can drive the driven wheel 24 connected to the belt 23 to rotate.

[0022] The driven wheel 24 is fixedly sleeved with the winding roller 4, and the other end of the rotating rod 21 is fixedly connected to the winding roller 3. The rotation of the rotating rod 21 can drive the winding roller 4 and the winding roller 3 to rotate synchronously.

[0023] The winding roller 3 is fixedly connected to a limit plate 31 on the outside, and a sleeve 32 is fixedly installed in the bracket 11. The winding roller 3 is rotatably arranged in the sleeve 32, and a cloth opening 33 is opened on the side surface of the sleeve 32. When the cloth is wound on the surface of the winding roller 3, the other end of the cloth is pulled out from the cloth opening 33 and connected to the winding roller 4. When the winding roller 3 starts to rotate inside the sleeve 32, the limit plate 31 is spiral, and the winding roller 3 can evenly pull the cloth produced by the large circular knitting machine. The spirally arranged limit plate 31 can rotate the cloth from the other end of the winding roller 3 and lead it out from the cloth opening 33, thereby ensuring that the cloth wound at the winding roller 3 can be evenly led out, avoiding the phenomenon that the cloth is broken due to excessive force during the winding and winding process.

[0024] A slide groove 12 is provided on the inner wall of the bracket 11 on the other side, and a telescopic rod 13 is provided inside the slide groove 12. A spring 14 is sleeved outside the telescopic rod 13. One end of the spring 14 is fixedly connected to the bottom of the slide groove 12, and the other end thereof is connected to the bottom of a slider 15. A slider 15 is fixedly provided on the top of the telescopic rod 13. The slider 15 is slidably connected to the slide groove 12. A connecting plate 5 is provided on the side of the slider 15. A rotating seat 51 is provided above the connecting plate 5. A pressing wheel 52 is rotatably provided on the rotating seat 51. The pressing wheel 52 is in contact with the cloth on the surface of the winding roller 4. When one end of the cloth is wound around the winding roller 4, the pressing wheel 52 is in close contact with the cloth. During the winding process, the cloth When the diameter starts to increase, it can push the pressing wheel 52 below, and the pressing wheel 5 drives the connecting plate 5 at the bottom to move downward. The connecting plate 5 drives the sliders 15 at both ends to slide in the slide groove 12, and then the spring 14 can be squeezed to generate a reverse thrust, so that the pressing wheel 52 can be in close contact with the cloth, which can avoid the cloth being torn and broken due to excessive speed during the cloth winding process. At the same time, after the winding is completed, the pressing wheel 52 can compact the cloth to make the cloth tighter, and inevitably loosen, which is not conducive to later transportation. The pressing wheel 52 is rotatably connected to the rotating seat 51, which can ensure the smoothness of the cloth winding, and the sliding friction is converted into rolling friction, thereby reducing the risk of cloth breakage.

[0025] Working principle:

[0026] The pulling and winding mechanism of the large circular machine, when working, winds the cloth produced by the large circular machine onto the winding roller 3, and then winds it onto the winding roller 4 again through the cloth opening 33. By turning on the switch of the motor 2, the motor 2 can drive the winding roller 3 and the winding roller 4 to rotate. The limiting plate 31 is arranged inside the winding roller 3 to transport the cloth at a uniform speed to avoid breakage during the pulling process of the cloth. The pressure wheel 52 at the bottom of the winding roller 3 can make the cloth be wound more tightly, and at the same time, it can avoid the winding roller 3 from speeding up when the cloth winding diameter is too large, resulting in cloth breakage.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
