Description

Automatic rolling device for tearing cloth of tire bead ring wrapping cloth

Technical Field

The utility model relates to a tire equipment technical field, concretely relates to tire bead ring infantees that simple structure, adaptability can be strong, efficient tear automatic rolling up device of cloth.

Background

In the manufacturing process of the existing high-load steel wire tire, a layer of nylon wrapping cloth formed by wrapping rubber outside nylon wires needs to be wound on the surface of a steel wire ring by a wrapping cloth winding machine, the nylon wrapping cloth wound on the steel wire ring is generally formed by rolling rubber materials on the surface of a nylon cord fabric through calendering equipment to form a large wrapping cloth roll, then the large wrapping cloth roll is cut into wrapping cloth strips with certain width through a multi-blade longitudinal cutting machine and a slitting machine, and finally the wrapping cloth roll is obtained through winding of a wrapping cloth rewinding machine to be used in the process of wrapping the steel wire ring. However, the nylon wrapping cloth has partial quality defects in the processes of gluing, removing the lining cloth from the wrapping cloth, and slitting the wrapping cloth, and in order to improve the yield of the nylon wrapping cloth, the defective wrapping strips need to be cut and removed after slitting. However, the wrapping cloth rewinder among the prior art generally adopts the mode of coaxial with fast coiling, and partial wrapping cloth tape leads to wrapping cloth to roll up the diameter and diminishes the back because of the quality problems intercepting, can cause wrapping cloth to roll up external diameter linear velocity different to can make and produce the problem of dragging because of the winding speed is asynchronous between a plurality of wrapping cloth tapes, not only influence the rolling quality, can lead to wrapping cloth tape to tear apart when serious moreover. Therefore, a plurality of independent tensioning wheels are arranged between the slitting machine and the wrapping cloth rewinding machine to adjust the tightness of wrapping cloth belts with different lengths, but the adjustment range of the tensioning wheels is limited, so that the wrapping cloth rewinding machine is difficult to adapt to the wrapping cloth belt winding after large-section cutting. Also have and set up a plurality of guide pulleys that independently go up and down from top to bottom between branch strip machine and infantees rewinder, through balancing weight on the guide pulley and the photoelectric switch who sets up from top to bottom, guide pulley and balancing weight are automatic to carry out the fine setting individually, and photoelectric switch cooperation controller adjusts the rolling speed of infantees rewinder and carries out the overall adjustment, thereby solve when batching respectively treat that the infantees strap is asynchronous and the problem of dragging that produces, but to the infantees strap after the intercepting overlength, need only can start the infantees rewinder behind the infantees strap of other overlengths of manual coiling alone, not only need controller and photoelectric switch cooperation, overall structure is comparatively complicated, and the reforming adaptability of infantees strap is relatively weak, production efficiency hangs down excessively.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, self-adaptability can the reinforce, efficient tire bead wire winding infantees tear automatic rolling up device of cloth.

The utility model discloses a realize like this: including deflector, drive roller, rolling running roller, rolling arm, back shaft, frame, vertical installation of frame and middle one side lower extreme set up horizontal deflector, the drive roller is rotatable to be set up in the middle of the frame of deflector side top, the one end of drive roller and drive arrangement's drive shaft connection, the back shaft is fixed to be set up in the middle one side of keeping away from the deflector in the frame, the articulated a plurality of rolling arms in interval on the back shaft, the rolling running roller is rotatable to be set up in the rolling arm and to keep away from the one end of back shaft and outer disc and tangent with the surface of drive roller.

The utility model has the advantages that: the utility model discloses a plurality of independent rolling arms are articulated on the back shaft, set up rotatable rolling running roller and tangent with the drive roller external diameter at the rolling arm other end, behind the infantees belt coiling on the rolling running roller excircle, can not take place to interfere between the wrapping cloth book on each rolling running roller, the wrapping cloth book that forms in the rolling process is tangent with the drive roller external diameter and rotates under the frictional force effect, because each rolling running roller can be along with rolling arm relative back shaft independent rotation, though the diameter of each corresponding wrapping cloth book after intercepting unqualified wrapping cloth section is different in the coiling process, but the external diameter linear velocity of each wrapping cloth book can keep in step under the effect of drive roller, thereby not only reach the coiling after the different length of self-adaptation wrapping cloth area intercepting, can also avoid the problem that can only start wrapping cloth rewinder after needing other overlength wrapping cloth tapes of independent manual coiling, improved production efficiency, the problem of dragging caused by different wrapping cloth roll lengths is effectively avoided; and the winding force of the wrapping cloth roll comes from the friction force between the wrapping cloth roll and the driving roller, so that the tension on the wrapping cloth belt can be in a controllable range during winding, and the problem that the wrapping strip is torn off in the winding process can be effectively avoided. Therefore, the utility model has the characteristics of simple structure, adaptability can the reinforce, efficient.
