Problems solved by technology

Due to the relative movement between the bottom of the tread and the conveyor belt, the actual movement distance of the tread is less than the set distance, which leads to an error in the length of the tread after cutting

Abstract

The invention relates to a tire forming device and especially relates to a conveying device capable of fixed-length cutting of a tire tread. The conveying device capable of the fixed-length cutting of the tire tread comprises a first servo motor, a second servo motor, a first servo drive, a second servo drive, a conveying belt, a cutter device, a length-counting encoder, a distance measurement sensor and a PLC control system. The device provided by the invention has the effects that (1) through coordination between guide rollers and pressing rollers, the tire tread can be kept smooth and centralized on the conveying belt in front of the cutter, and errors caused by deflection of the tire tread position can be reduced; (2) the laser distance measurement sensor detects a gradient of a cutting mouth, so that measurement errors caused by inaccurate detection can be effectively reduced; (3) by pressing feet of the cutter, the tire tread position can be kept steady during cutting; (4) by the novel detection method, accuracy for a cutting length can be increased; and (5) by the length-counting encoder, influences brought by sliding between the tire tread and the conveying belt can be reduced.

Description

technical field [0001] The invention relates to a tire building device, in particular to a tire tread cutting method to length. Background technique [0002] The tread fixed-length cutting device is an important part of the tread extrusion line. Its function is to cut the continuous tread on the production line according to the set length. Since the tread is the part that the tire directly contacts with the road surface, the cutting The accuracy of the rear tread length directly affects the performance of the tire. [0003] The working principle of the existing tread fixed-length cutting device is that after the tread moves longitudinally on the conveyor belt to a set length, the cutting knife performs horizontal cutting, and the conveyor belt and cutting are all servo-controlled. Due to the relative movement between the bottom of the tread and the conveyor belt, the actual movement distance of the tread is less than the set distance, which leads to an error in the length o...
