Tension control device for zero-degree belt layer winding process

Abstract

The invention provides a tension control device for a zero-degree belt layer winding process. The tension control device comprises a winding displacement assembly, a driving system and a tension detecting system. The winding displacement assembly comprises a winding displacement frame, and the winding displacement frame is sequentially provided with a guide wheel, a first transition wheel, a powerwheel, a tension wheel, a second transition wheel and a third transition wheel from a rubber material inlet. The first transition wheel, the tension wheel and the third transition wheel are distributed on the upper area of the front side of the winding displacement frame, and the power wheel and the second transition wheel are distributed on the lower area of the front side of the winding displacement frame. A rubber material passes through the lower side of the guide wheel, is wound around the first transition wheel, goes out from the lower side of the power wheel, then is wound around the upper side of the power wheel, passes out from the lower side of the second transition wheel, and finally passes out from the upper side of the third transition wheel and enters a winding head. The driving system comprises a servo motor and a transmission assembly, and the servo motor drives the power wheel to run through the transmission assembly. The tension detection system comprises a sensing assembly and a detecting assembly, and the sensing assembly is connected with the tension wheel so as to be stressed in the vertical direction. The detecting assembly comprises a base plate and a sensor, the upper surface of the base plate abuts against the sensing assembly, the sensor is fixed to the lower surface of the base plate, and the sensing assembly applies vertical stress to the sensor through the base plate.

Description

technical field [0001] The invention belongs to the field of all-steel radial tire preparation, and in particular relates to a rubber material tension control device in the zero-degree belt layer winding process. Background technique [0002] The application of all-steel radial truck tires is increasing, and the cap winding machine is one of the important equipment in the production of high-grade radial tires. The currently commonly used cap winding machine is composed of a guide device, a material storage device and a winding device. After the rubber material is guided, it enters the cap winding device through a buffer device, and is finally attached to the belt drum by the winding head. During the winding process, the unstable tension of the rubber material not only affects the winding speed, but also causes tire defects such as rubber material detaching from the material tray, arching after winding, and winding too loose or too tight. Patent CN200720097973.7 relates to a...

Patent CN200720097973.7 relates to a wrapping machine for narrow crown belt parts. The tension control motor on the wrapping device keeps rotating synchronously with the drive motor of the belt drum, and then buffers and adjusts the tension through a plurality of guide rollers. The main force of the structural rubber is divided into the traction tension of the belt drum to the rubber and the feeding tension of the tension control motor to the rubber. In the actual application process, the motor on the belt drum side takes the positioning mode, and the tension control motor outputs torque. The two are difficult. Matching will cause large tension fluctuations
