Description

Automatic bead extracting machine from used tire by rack gear mechanism}

With the development of the automobile industry and the improvement of living standards, tens of millions of waste tires are generated annually, which is a serious environmental pollution problem, but it is not easy to deal with it. It is difficult to incinerate continuously because of the bead remaining after incineration even if you try to incinerate, and the bead, which is a high-strength steel wire, is buried even if you want to crush and reuse Not only was it easy to grind, but it was also difficult to separate rubber and steel wire even after grinding.

BID is embedded in the ring part of the tire and is covered with high-strength polyester yarn, and it is extremely difficult to separate it, so the efficient machine has not been developed until now. As a method of using a method such as the tire is divided into a press and withdrawal using a hydraulic hook, but there is a limit in processing because the productivity is not high because it is not automated.

The present invention relates to a machine for automatically removing and removing beads from a tire as a machine for solving such a problem.

The present invention automatically withdraws the bead from the input waste tires, and automatically discharges the bead-removed tires to increase productivity, and promote the recycling of waste tires.
