Description

A scrap rubber crawler steel wire cutter mechanism

technical field

The invention relates to the field of waste rubber material recycling, in particular to a scrap rubber crawler steel wire cutter mechanism.

Background technique

The track consists of track shoes and track pins. The track pins connect each track shoe to form a track link. There are holes at both ends of the track shoe, which mesh with the driving wheel, and there are guiding teeth in the middle, which are used to straighten the track and prevent the track from falling off when turning or rolling. In order to improve the firmness of the track shoes and the adhesion between the track and the ground. According to the classification of raw materials, the crawler can be mainly divided into rubber crawler and steel crawler. Among them, the rubber rubber crawler chassis is mostly suitable for small light industry and small construction machinery industry. Light industry is generally agricultural machinery within one ton to four tons; construction machinery industry is mostly used in small drilling industry. When the crawler is worn or damaged after long-term use of the machine, which affects the performance of the crawler, it is necessary to replace the rubber crawler, and the replaced crawler is treated as waste rubber material.

The main structure of the rubber track is the rubber attached to the surface, the internal embedded parts and the steel wire. In view of the increasing number of waste rubber tracks, the recycling of waste rubber is an important environmental issue. The purpose of using the recycling device for waste rubber tracks is to separate and classify the embedded parts, steel wires and surface rubber of the rubber track. Recycle. After cutting off the rubber track, removing the surface rubber, and peeling off the embedded parts, there are still steel wires left in the waste rubber material, and each steel wire has a long length. The collection of steel wire waste is very difficult. It is necessary to use the cutting mechanism of the steel wire to cut it in sections to ensure that the steel wire is collected in the form of small sections. The existing waste rubber material recovery device is not specially provided with a cutting device for the tie wire, which causes the tie wire to be too long and coiled, and it is difficult to collect the wire.
