Wheel refurbishment equipment is a kind of rubber machinery, which refers to a complete set of special equipment that can process and repair old tires to achieve tire recycling.
Wheel refurbishment equipment includes two types of cold rewinding equipment and hot rewinding equipment. There are sanders, tire presses, vulcanizers, and glue guns. Grinders are used to grind old tires out of the arc required for retreading. They are usually equipped with vacuum cleaners. There are horizontal sander, vertical sander and CNC sander. Tire press, also known as tread press. It is used to uniformly press the tread rubber on the carcass according to the size and tension specified by the process; it can effectively remove the air between the tread and the carcass. Also divided into vertical tire press, horizontal tire press, CNC tire press. The vulcanization tank is used to vulcanize the tire with a high temperature, so that the tread and the tire body are firmly combined. Divided into electric heating and steam heating. Electric heating vulcanizers have better performance.
Development of wheel refurbishment equipment:
Tire retreading has been in China for decades. Prior to the 1980s, relatively backward hot-rolling equipment had been used, with low production efficiency, great damage to the carcass, and low service life. A tire can only be retreaded once. After the 1980s, China began to introduce foreign advanced cold turning equipment. One vulcanizer can vulcanize multiple tires at the same time, greatly improving work efficiency. Because the cold vulcanization temperature is lower (the cold vulcanization temperature is generally about 115 degrees Celsius, while the hot turn is about 150 degrees Celsius), the tire is less harmful, mostly with strong wear resistance, and the service life can reach 80% of the new tire % Even higher! A tire can be retreaded multiple times. Therefore, domestic tire retreading plants mostly use cold-turning equipment, but there are still some tire-turning plants using hot-turning.
Since the introduction of cold turning equipment, it has a history of 30 years. With the efforts of several generations of tire retreaders, great progress has been made, but because of the impact of the domestic investment environment, there is still a little gap with the international level. Bai Ying, a domestic first-class engineer, once said to the author: “I can design the most advanced equipment in the world, but I have no market in China.”
In general, the technology and equipment quality of tire retreading equipment have been greatly improved in recent years. Cost performance is not necessarily worse than foreign equipment! At present, the most advanced equipment in the world is Italy’s horse wheel solid force. Their equipment is the best in the industry in terms of advanced level and service life, but it is not very good in the domestic market for some special reasons. The most advanced domestic equipment is the Shanghai Brads tire retreading equipment. Brads’ equipment is close to China’s national conditions and has a high cost performance.
