Background

At present, in the tire production process, after a belted layer passes through a conveying device, the belted layer enters a curling station, the belted layer is collected in a tool barrel, and meanwhile, a layer of plastic paper is arranged between every two belted layers to ensure that the belted layer is not firmly adhered. In the winding process, if the plastic paper unwinding tension and the tool winding speed are improperly controlled, the phenomena of material folding, drooping, curling deflection and the like are easily caused, so that the product quality is influenced. In order to effectively improve the product quality and reduce the production cost, a belt winding device is urgently needed.

Chinese patent CN101306581 discloses a method and a system for winding a tire tread, which specifically comprises extruding a rubber film by an extruder, cooling the rubber film by a film cooling roller, simultaneously pasting a plastic film by a film covering mechanism, and then winding and storing the film by a winding mechanism. Although the above patent discloses that the belt layer needs to be adhered with plastic paper for curling preservation, there is no specific solution to the specific structure of the curling mechanism and the problems of material folding, drooping and curling deflection caused by improper control of plastic paper unwinding tension and tool winding speed in the curling process. In addition, chinese patent CN210283177U discloses an automatic sheet winding speed tracking control system for a plastic extrusion line, which specifically comprises an HMI unit, a torque motor, an encoder, a winding motor, a winding frequency converter and a PLC controller. The HMI unit can receive traction speed parameters input by a user, and the torque motor is used for driving a traction roller of the tractor to rotate.

Above-mentioned technical scheme is only applicable to the rolling speed of single kind of sheet, do not relate to the laminating of two kinds of materials and the control mode of rolling speed, and the control mode of its rolling speed is for detecting the angle displacement information of carry over pinch rolls through the encoder, the PLC controller can be based on the pulse signal that the encoder sent, calculate the actual pulling speed of carry over pinch rolls, and send the analog signal for the rolling converter, thereby adjust the rotational speed of rolling motor, make the rotational speed of rolling axle and the rotational speed of carry over pinch rolls keep unanimous, can the rotational speed of automatically regulated rolling axle, but the encoder has the relatively poor problem of fault detection mechanism reliability, signal detection delay is too long, the problem that probably leads to the signal to miss the detection when speed is fast.
