Material unwinding and winding device and speed regulating method thereof

Abstract

The invention discloses a material unwinding and winding device and a speed regulating method thereof. By adopting the device and the method for automatically monitoring and controlling the winding speed of mat cloth, the winding speed of the mat cloth can be reduced gradually in stages, so that the winding speed of the mat cloth is roughly kept stable and basically synchronous with the material conveying speed, the material is continuously and uniformly conveyed to a feeding rack on the premise that shutdown and speed limit are not needed, and the production efficiency of winding, jointing and fixed length cutting of the material is improved. The material unwinding and winding device comprises a material winding device, a mat cloth winding device and an unwinding bracket. A thickness detection device for detecting the winding thickness of the mat cloth and a driving device for driving a scroll to rotate and regulating the revolution speed of the scroll according to the thickness detection result are arranged on one side of the mat cloth winding device. The scroll continuously rotates to wind the mat cloth under the action of the driving device, and meanwhile, the material is separated from the mat cloth on the unwinding bracket and conveyed forwards to the feeding rack.

Description

technical field [0001] The invention relates to a material guiding and coiling device and a speed regulating method thereof, which belong to the field of rubber machinery. Background technique [0002] The existing rubber tire manufacturing process requires lamination and rolling of various parts that constitute the semi-finished tire on the forming drum, such as conveying and winding materials such as steel cord, inner liner or belt layer to the forming drum in sequence Then cut to length. [0003] According to the requirements of laminating process, the above materials need to be separated from the pad cloth wrapped in the outer layer. In order to improve the separation efficiency and relieve the labor load of manual operation, the motor is usually used to drive the reel to rotate. At the same time, the pad cloth is rolled up on the other side. [0004] The unwinding of the material and the take-up of the pad cloth are carried out at the same time, because the thickness ...

AI Technical Summary

Problems solved by technology

When the take-up speed of the pad cloth obviously exceeds the material conveying speed, it will not only form a pull on the material and affect its surface tension, but also disturb the rhythm control of the material conveyed to the feeding frame, and affect the winding and fixed length of the material on the forming drum Cutting process control

[0005] The usual solution is to temporarily stop feeding the material to the feed rack or to manually limit the speed of the pad cloth from being too fast, so it cannot fundamentally solve the problem that the speed of the pad cloth is not synchronized with the material conveying speed. This kind of problem will occur again, and the repeated stop and speed limit will lead to the reduction of the whole work efficiency
