Ultrasonic cutting device and cutting method

Abstract

The invention belongs to the technical field of tire molding, and discloses an ultrasonic cutting device and cutting method. The ultrasonic cutting device is disposed on a conveying device of sizing material composite parts, and the ultrasonic cutting device comprises a driving mechanism, an ultrasonic cutter assembly, a position detecting mechanism, a storage unit and a control unit. The ultrasonic cutter assembly is driven by the driving mechanism to move in the width direction of the conveying device. The position detecting mechanism is used for detecting position information of the ultrasonic cutter assembly. The sizing material composite parts have different thickness values at different positions in the width direction of the conveying device, and the storage unit is used for storingstate information corresponding to the thickness values. The control unit adjusts the working state of the ultrasonic cutter assembly according to the position information detected by the position detecting mechanism and the state information stored in the storage unit. According to the ultrasonic cutting device and cutting method, the control unit cooperates with the position detecting mechanismand the storage unit to adjust the working state of the ultrasonic cutter assembly, so that the precise control over ultrasonic cutters is realized.

Description

technical field [0001] The invention relates to the technical field of tire building, in particular to an ultrasonic cutting device and a cutting method. Background technique [0002] At present, in the processing of rubber tires, it is necessary to cut the rubber material according to the tire specifications and manufacturing process. Different from the previous physical cutting, the existing more advanced and widely used cutting process is to use ultrasonic cutting device. Ultrasonic cutting uses ultrasonic high-frequency oscillation to vibrate the molecular chain of the rubber material, so the cross-section of the rubber material is relatively smooth, and the adhesiveness of the subsequent rubber material lamination is also better. However, it is necessary to be very cautious when using an ultrasonic cutting device, because the ultrasonic cutter body must not experience air vibration and stagnation during cutting, otherwise it is very easy to cause damage.

Problems solved by technology

In the existing tire building equipment, a proximity switch is set according to the thickness distribution position of the rubber compound to determine the control switching point of the cutting knife walking speed. Therefore, when it is necessary to cut rubber compound parts of different sizes The installation position of the proximity switch should match the thickness distribution of the rubber compound. The whole adjustment process is difficult and time-consuming, which makes it difficult for the tire building equipment to adapt to the processing and production requirements of tires with different size parameters.
