Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an anti-rewinding device for a circular knitting machine. Background Art

[0002] In the textile industry, the stability and reliability of cloth winders are crucial to production efficiency and product quality. During the cloth winding process, the uniformity of the cloth tension plays a decisive role in the winding effect. Improper tension settings or malfunctions in the tension control system can lead to inconsistent tension on both sides of the cloth, which can easily cause uneven fabric sliding and, in turn, backwinding. The bearings of the cloth winder are key components that support and rotate the parts. Prolonged operation or lack of effective maintenance can lead to increased bearing wear and even failures, such as bearing imbalance and seizure. These can cause the cloth winder to backwind, which not only impacts production schedules but can also compromise fabric quality and potentially damage the equipment itself. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, a knitting circular knitting machine cloth winding machine anti-rewinding device includes a main body 1 and a bracket 8. The auxiliary roller 4 and the second rubber roller 3 are rotatably connected on the inner side of the main body 1, the first rubber roller 2 is installed on the inner side of the main body 1, the inner side of the bracket 8 is rotatably connected to the winding roller 7, the inner side of the bracket 8 is installed with an anti-rewinding mechanism 6, the inner side of the main body 1 is rotatably connected to the first limiting roller 5, and the first limiting roller 5 is located above the second rubber roller 3.

[0035] Example 2

[0036] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0037] The anti-rewind mechanism 6 includes an elastic telescopic rod 606, the end of which is fixedly connected to the connecting piece 603, and the side of the connecting piece 603 is rotatably connected to the cloth winding roller 601. A groove 604 is provided on the side wall of the bracket 8, and the elastic telescopic rod 606 is fixedly connected to the lower surface of the groove 604. A pressure sensor 605 cooperating with the connecting piece 603 is fixedly connected to the side wall of the groove 604. The side of the winding roller 7 is rotatably connected to the second limiting roller 602. The second limiting roller 602 is located above the cloth winding roller 601. The tension on the surface of the cloth will act on the surface of the cloth winding roller 601. Therefore, the greater the tension on the surface of the cloth, the greater the pressure on the cloth winding roller 601. When the cloth winding roller 601 is subjected to pressure, the cloth winding roller 601 drives the connecting piece 603 to press the elastic telescopic rod 606 downward. When the connecting piece 603 contacts the pressure sensor 605, the pressure sensor sends a signal to alert the operator.

[0038] Example 3

[0039] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0040] The surfaces of the first rubber roller 2 and the second rubber roller 3 are against each other. The first rubber roller 2 and the second rubber roller 3 have the same model. The diameters of the first rubber roller 2 and the second rubber roller 3 are larger than the common diameter specifications. The end of the second rubber roller 3 passes through the main body 1 and is fixedly connected to a turntable. The end of the first rubber roller 2 is fixedly connected to the first gear 10, and the end of the second rubber roller 3 is fixedly connected to the second gear 9. The second gear 9 is engaged with the first gear 10. The second gear 9 and the first gear 10 are located outside the main body 1. The end of the first rubber roller 2 is rotatably connected to the slider, and the slider is slidably connected to the main body 1. A convex portion is provided at the end of the slider, and the convex portion is fixedly connected to the main body 1 by a bolt. The diameters of the first rubber roller 2 and the second rubber roller 3 are larger than the common diameter specifications, which can increase the surface stroke of the first rubber roller 2 and the second rubber roller 3 and increase the service life.

[0041] Working principle: The cloth passes through the auxiliary roller 4, between the first rubber roller 2 and the second rubber roller, the cloth rolling roller 601 and the winding roller 7 in sequence. When the cloth passes between the first rubber roller 2 and the second rubber roller, if the cloth deviates, the first limiting roller 5 can limit the position of the cloth. When passing through the cloth rolling roller 601, the second limiting roller 602 is similar. If the surface tension of the cloth is too large, it may roll back. When the surface tension of the cloth increases, the cloth presses the cloth rolling roller 601, and the pressing of the cloth rolling roller 601 drives the connecting piece 603 to move downward, and the elastic telescopic rod 606 is compressed and contracted. When the surface tension of the cloth winding roller 601 reaches the expected value, the connecting piece 603 moves downward and contacts the pressure sensor 605. At this time, the pressure sensor 605 sends a signal to remind the staff to reduce the occurrence of backwinding. The end of the first rubber roller 2 is rotatably connected to the slider, and the slider is slidably connected to the main body 1. A convex portion is provided at the end of the slider, and the convex portion is fixedly connected to the main body 1 by a bolt, which can facilitate the staff to adjust and disassemble the position of the first rubber roller 2 for maintenance, so that the interval between the first rubber roller 2 and the second rubber roller 3 can be adjusted according to the different thickness of the cloth, and the applicability is wider.
