Description

Technical Field

[0001] The utility model relates to the technical field of tire processing, in particular to a rubber vulcanization preheating device. Background Art

[0002] Tire vulcanization refers to the vulcanization of the outer tire, which is carried out by model pressurization. Through vulcanization, the linear polymer in the plastic rubber undergoes a cross-linking reaction to generate a network of polymer materials, which appears to be solidified on a macro scale and becomes a highly elastic rubber with practical value. In the existing production process, the tire blank needs to be preheated before being transported to the vulcanizer, and then transported to the side of the vulcanizer before vulcanization, and vulcanized in the vulcanizer.

[0003] A rubber vulcanization preheating device is disclosed in a Chinese utility model patent with a publication number of CN217729400U. By setting a rotating disk structure, the problem of uneven heating of the tire during use of the preheating device of the patent cited in the background technology is solved. A plurality of electric heating tubes are inserted on both sides of the inner cavity, and a motor mechanism is installed at the bottom of the rotating disk. When the tire is preheated, the rotating disk is driven by the motor to rotate at a uniform speed, so that the outside of the tire can be fully preheated to avoid the situation of concentrated heat accumulation in a certain part. The overall structure is simple and practical.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: after preheating the rubber tire, the device is not convenient enough to take out the preheated tire, and workers need to reach into the box to take out the tire. At the same time, when the tire is taken out, the limit rod and the column may affect the removal of the tire, which is very inconvenient and easily affects the overall work efficiency of rubber vulcanization.
