Description

Technical Field

[0001] The utility model relates to the technical field of tire processing equipment, in particular to a tire processing device for a rice transplanter. Background Art

[0002] Rice transplanter tires are specially designed for rice transplanters to support and move the machine. Compared with traditional vehicle tires, rice transplanter tires usually use solid rubber wheels or pneumatic rubber wheels, while traditional vehicle tires usually use pneumatic rubber wheels. Solid rubber wheels have no inner tube and gas support, so they are more wear-resistant, pressure-resistant, and not easy to rupture. At the same time, they do not need to be inflated, are safer, and have a relatively long service life.

[0003] During the production of some rice transplanter tires, the outer side of the metal wheel hub is directly placed in the mold, so that the molded rubber tire and the wheel hub can be directly integrated into one. At the same time, since the rice transplanter tire is a solid rubber structure, the tire and the mold will stick together after molding, and it is difficult to quickly demold the molded tire from the mold. The traditional ejector demolding method, because the solid rubber tire is heavy and the diameter of the ejector is usually small, if the tire is large or heavy, the ejector may not be able to withstand the pressure, resulting in the tire cannot be ejected smoothly. The ejector is usually made of metal. If it is not operated properly or used in an irregular manner, it may cause scratches or damage to the tire, affecting the quality and service life of the tire.
