As shown in fig. 1-4, a cloth winding mechanism comprises a delivery roller 1, a pressure bar 2, a cloth pressing roller 3 and a material receiving roller 4 which are arranged in sequence along the delivery direction of a cloth 5; wherein the lowest point of the pressure lever 2 is lower than the highest point of the cloth pressing roller 3; the cloth is conveyed from the conveying roller 1, firstly passes through the lower side of the pressure lever 2, then passes through the upper side of the cloth pressing roller 3 in an obliquely upward motion, and finally is wound by the material receiving roller 4; namely, in the area of the press rod 2 and the cloth pressing roller 3, the cloth 5 moves in an S shape.

The pressure lever 2 comprises a rotating sleeve 21 and a pressure lever shaft 22; two ends of the pressure lever shaft 22 are connected with the lifting support 6, so that the position of the pressure lever 2 can be adjusted in the vertical direction, and the tension of the cloth 5 in the coiling process can be flexibly adjusted according to the condition of the cloth and the actual production requirement.

The rotating sleeve 21 is sleeved on the pressure rod shaft 22 and is coaxially arranged (two ends of the pressure rod shaft 22 extend out of the rotating sleeve 21); when the cloth feeding device works, the outer surface of the rotating sleeve 21 is in contact with the cloth 5; the rotating sleeve 21 can rotate on the pressure rod shaft 22 by taking the central shaft of the pressure rod shaft 22 as a rotating shaft, namely, any point on the contact surface of the rotating sleeve 21 and the cloth 5 can rotate around the central shaft of the pressure rod shaft 22 (namely, the pressure rod 2); therefore, the cloth 5 can smoothly pass through the pressure lever 2, and compared with the traditional pressure lever which cannot rotate, the friction is reduced, so that the scratching and the damage to the cloth surface are reduced, the defective rate is reduced, and the quality of the cloth 5 is improved.

Limiting pieces 23 are symmetrically arranged on two sides of the rotating sleeve 21; the limiting piece 23 is of a circular cylindrical structure and is also sleeved on the pressure rod shaft 22; the side surface of the limiting piece 23 is provided with a threaded through hole 231; correspondingly, the pressure rod shaft 22 is provided with an insertion hole 221 which has the same inner diameter and corresponds to the threaded through hole 231; the threaded through hole 231 and the insertion hole 221 may be connected by a cylindrical connection member 7 (e.g., a screw or a stud) having a mating thread with the threaded through hole 231; thereby clamping the rotating sleeve 21 between the stoppers 23 so that the rotating sleeve 21 does not slide along the length direction of the pressure rod shaft 22 (i.e., the position of the rotating sleeve 21 in the length direction of the pressure rod shaft 22 is restricted); the end surfaces of the two ends of the rotating sleeve 21 (i.e. the contact surface between the rotating sleeve 21 and the limiting member 23) are provided with the smooth and wear-resistant first polytetrafluoroethylene layer 211, which not only facilitates the relative movement between the rotating sleeve 21 and the limiting member 23, but also reduces the wear.

The rotating sleeve 21 is a ceramic sleeve with smooth surface; compared with metal materials, the ceramic sleeve has better wear resistance and smaller friction coefficient; the inner surface of the ceramic sleeve (namely the contact surface of the rotating sleeve 21 and the pressure rod shaft 22) is provided with a second polytetrafluoroethylene layer 212, so that the rotating sleeve 21 can conveniently rotate on the pressure rod shaft 22, and the service life is prolonged; meanwhile, a phase-change material interlayer 213 with an annular radial section is arranged in the ceramic sleeve; the phase change material interlayer 213 is internally provided with a microcapsule solid-liquid phase change material with the phase change point of 20-35 ℃; the solid-liquid phase change material is in a solid state below a phase change point; when the ambient temperature exceeds the phase change point, the material undergoes phase change from a solid state to a liquid state and absorbs heat, thereby reducing the ambient temperature; the solid-liquid phase change material is encapsulated by microcapsules, so that the leakage of the solid-liquid phase change material during phase change into a liquid state can be reduced; when the rotating sleeve 21 rotates on the pressure rod shaft 22 for a long time, heat is generated due to long-term friction to increase the temperature; the phase-change material interlayer 213 can absorb heat and reduce temperature, so that the rotating sleeve 21 and the pressure rod shaft 22 are protected, and the cloth 5 is also protected; meanwhile, the temperature of the rotating sleeve 21 is also raised due to friction when the cloth 5 passes over the rotating sleeve 21 for a long time, and the phase-change material interlayer 213 can absorb heat through phase change to protect the rotating sleeve 21 and the cloth 5.

In addition, the surface of the cloth pressing roller 3 is sequentially provided with a phase change material sleeve 31 and a chromium coating 32 from inside to outside; the phase-change material sleeve 31 is of a cylindrical structure, and the wall of the phase-change material sleeve is hollow; the microcapsule phase change material is arranged in the cylinder wall, and heat generated by long-term friction of the cloth 5 on the cloth pressing roller 3 is reduced through phase change heat absorption of the phase change material; the phase-change material sleeve 31 is sleeved on the cloth pressing roller 3 and fixedly connected by a conventional method; the chromium plating layer 32 can improve the surface hardness and wear resistance of the cloth pressing roller 3.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
