Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to a cloth anti-wear device. Background Art

[0002] When the cloth is conveyed, rollers and support rods are needed to guide and support it. The cloth will deviate left and right on the rollers when moving, which will affect the winding and processing of the cloth. The edges of the cloth may even deviate to contact the frames on both sides, causing friction, wearing the edges of the cloth and reducing the quality of the cloth. Utility Model Content

[0003] The utility model aims to provide a cloth wear-proof device, which has the advantage of preventing the cloth from deviating left and right on a supporting rod.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A cloth wear prevention device comprises a support rod, a rod sleeve and a sliding sleeve, the rod sleeve is sleeved on the support rod and is slidably connected to the support rod, baffles are fixedly connected to the openings at both ends of the rod sleeve, a plurality of guide rods are fixedly connected between the baffles at both ends, a square slide groove is provided at the middle part of the rod sleeve, a square clamping block is embedded in the slide groove, a wedge block is fixedly connected to the end of the clamping block away from the sliding sleeve, a square through hole is provided in the sliding sleeve, the sliding sleeve is sleeved on the outside of the rod sleeve, the rod sleeve is located in the square through hole of the sliding sleeve, the guide rod passes through the sliding sleeve and is slidably connected to the sliding sleeve, a spring is sleeved on the outside of the rod sleeve, and both ends of the spring are respectively fixedly connected to the rod sleeve sliding sleeve.

[0006] By adopting the above technical scheme, the rod sleeves are respectively sleeved on the two ends of the cloth support rod, and the cloth is located between the two rod sleeves; the inner wall of the sliding sleeve generates pressure on the wedge block, so that the block is pressed against the support rod, the rubber pad is deformed, and friction is generated between the rubber pad and the support rod, thereby fixing it on the support rod; according to the cloth of different widths, the sliding sleeve is moved toward the end of the rod sleeve to separate the inner wall of the sliding sleeve from the wedge block, the rubber pad returns to its original state, and the friction between the rubber pad and the support rod is reduced; at the same time, the movement of the sliding sleeve causes the spring to generate elastic force, and the spring generates force on the blocking piece of the rod sleeve, thereby driving the rod sleeve to move close to the edge of the cloth, and then the spring rebounds, driving the sliding sleeve back to the middle of the rod sleeve, and the inner wall of the sliding sleeve pushes the blocking block to move along the sliding groove toward the inside of the rod sleeve and press against the support rod, so that the rod sleeve is fixed again, and the cloth is restricted by the blocking piece of the rod sleeve and will not deviate left and right.

[0007] Preferably, friction patterns are formed around the exterior of the sliding sleeve.

[0008] The adoption of the technical solution makes it easy to move the sliding sleeve.

[0009] Preferably, the width of the end of the block located in the rod sleeve is greater than the inner diameter of the sliding groove.

[0010] The above technical solution is adopted to prevent the block from falling out of the slide groove.

[0011] Preferably, there are four guide rods which pass through the sliding sleeve and are slidably connected thereto.

[0012] The above technical solution is adopted to increase the stability of the sliding sleeve.

[0013] Preferably, there are four clamping blocks, which are respectively embedded in the sliding grooves provided in the sliding sleeve and are slidably connected with the sliding sleeve.

[0014] By adopting the above technical solution, the friction between the sliding sleeve and the support rod is increased, so that they are fixed more firmly. BRIEF DESCRIPTION OF THE DRAWINGS
