Tire steel wire ring coating cloth tearing and automatic rolling-up device

Abstract

The invention discloses a tire steel wire ring coating cloth tearing and automatic rolling-up device. The device comprises a guide plate, a drive roller, a winding roller wheel, winding arms, a support shaft, and a machine frame, wherein the machine frame is vertically arranged, the guide plate is arranged on one side of the middle of the machine frame, the drive roller is rotatably arranged at the position, above the side of the guide plate, of the middle of the machine frame, one end of the drive roller is connected with a drive shaft of a drive device, the support shaft is fixedly arrangedon the side, away from the guide plate, of the middle of the machine frame, a plurality of winding arms are hinged to the support shaft at intervals, the winding roller wheel is arranged at the end, away from the support shaft, of the winding arm in a rotatable mode, and the outer circle surface of the winding roller wheel is tangent to the surface of the drive roller. According to the device, theplurality of independent winding arms are hinged to the support shaft, the other end of the winding arm is provided with the winding roller wheel which is tangent to the outer diameter of the drive roller, and thus the winding quality of various coating cloth coils after unqualified cloth segments are cut off in the winding process can be automatically adapted, the problem of pulling caused by the fact that the speeds of original winding roller wheels are the same but the coating cloth coil diameters are different is solved, and the device has the characteristics of being simple in structure,high in adaptability and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of tire equipment, in particular to an automatic rolling-up device for tire bead cloth tearing cloth with simple structure, strong self-adaptability and high efficiency. Background technique [0002] In the manufacturing process of existing high-load steel wire tires, it is necessary to use a wrapping winding machine to wind a layer of nylon wrapping cloth composed of nylon wire outer covering rubber on the surface of the bead ring, and the nylon wrapping cloth wrapped around the bead ring is generally passed through calendering equipment. Paste the rubber on the surface of the nylon cord and roll it into a large roll of cloth, and then cut it into a cloth tape of a certain width through a multi-knife slitting machine and a slitting machine, and finally take it out through a cloth rewinding machine Cloth wrapping rolls for use in the traveler wrapping process. However, there will be some quality defects in ...

AI Technical Summary

Problems solved by technology

However, there will be some quality defects in the process of coating the nylon cloth, removing the interlining cloth and cutting the cloth. In order to improve the yield of the nylon cloth, it is necessary to intercept and remove the defective edge strips after cutting.

However, the wrapping rewinding machines in the prior art generally adopt the coaxial and same-speed winding method. When part of the wrapping belt is intercepted due to quality problems and the diameter of the wrapping roll becomes smaller, the outer diameter of the wrapping roll will be reduced. The line speed is different, which will cause pulling problems between several wrapping belts due to the asynchronous winding speed, which not only affects the winding quality, but also causes the wrapping belts to break in severe cases

For this reason, there are also multiple independent tensioning wheels set between the slitting machine and the cloth rewinding machine to adjust the tightness of the cloth belts of different lengths. However, due to the limited adjustment range of the tensioning wheels, it is difficult to adapt to large sections. Rewinding of the cut wrapping tape

There are also multiple guide wheels that can be independently lifted up and down between the slitting machine and the cloth rewinding machine. Through the counterweight on the guide wheel and the photoelectric switch set up and down, the guide wheel and the counterweight are automatically fine-tuned individually. The photoelectric switch cooperates with the controller to adjust the winding speed of the cloth rewinding machine for overall adjustment, so as to solve the pulling problem caused by the out-of-synchronization of the cloth tapes to be rolled during winding, but for the cloth tapes that are cut too long , it is necessary to manually wind other too long wrapping tapes separately to start the wrapping rewinding machine, which not only requires the cooperation of the controller and photoelectric switch, but the overall structure is more complicated, and the adaptability of the wrapping tapes is weak, and the production efficiency too low
