Waste tire cutting device

Abstract

The invention provides a waste tire cutting device. The device comprises a rotary device, a lifting device, a feeding device, a cutting device and a discharging device, wherein the rotary device comprises a rotary shaft and a first telescopic device arranged on the rotary shaft, the first telescopic device is provided with a working state of extending outwards to abut against an inner ring of a tire so as to fix the tire and a contraction state of retracting and releasing limiting on the tire; the lifting device comprises a bearing plate which is arranged around the rotary shaft and a second driving device which drives the bearing plate to move along an axis of the rotary shaft, and the bearing plate has a first position where the inner ring of the tire is aligned with the first telescopicdevice and a second position where the tire gets rid of interference of the rotary device in the movement process; and the feeding device comprises an action end for moving the tire to the bearing plate. According to the design, firstly, automatic feeding and automatic discharging can be realized, the labor is saved, the efficiency is improved, and the safety in the machining process is improved;and secondly, the waste tire is fixed by expanding the waste tire through the first telescopic device, and the device has high adaptability to the waste tires with different types and sizes.

Description

technical field [0001] The invention relates to the technical field of waste tire recycling equipment, in particular to a waste tire cutting device. Background technique [0002] The annual waste tires produced in China are increasing at a rate of 8% to 10%. In 2010, the amount of waste tires produced in China reached about 250 million, while the recycling rate was only about 50%, resulting in a huge waste of resources. Therefore, the recycling and reuse of waste tires has attracted more and more attention. [0003] In the tax recycling process of waste tires, due to the complex structure and composition of waste tires, it is difficult to directly deal with them, so it is generally processed step by step. The first step in processing waste tires is usually shredding and cutting. The whole waste tires are cut into small pieces and the steel wires are removed. Therefore, how to efficiently and stably cut waste tires is a key issue to promote the recycling of waste tires. ...
