Description

Technical Field

[0001] The utility model relates to the field of tire production devices, in particular to a cooling roller. Background Art

[0002] As is known to all, the cooling method of the cooling roller used in the tire component production process is as follows: low-temperature water enters the clean water cavity of the main shaft of the cooling roller through the rotary joint water inlet pipe, enters the interlayer through the water inlet pipe to cool the cooling roller, and finally returns to the rotary joint through the return water branch pipe and the return water clean water cavity, forming a low-temperature water circulation system. However, the scale generated by the long-term circulation of the low-temperature circulating water of the existing cooling roller in the interlayer exists in the cooling roller for a long time, blocking the channel; after being blocked, it cannot be cleaned, causing the water circulation system to be blocked, affecting the cooling effect of the cooling roller. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a cooling roller, which avoids the blockage of the circulation channel of the cooling medium by impurities, reduces the purchase cost, and improves the quality of the semi-finished rubber parts.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a cooling roller, provided with a cylindrical roller body, the roller body is coaxially installed on a hollow shaft, a cooling cavity is formed between the inner wall of the roller body and the outer wall of the hollow shaft, the cooling cavity is respectively connected with a water inlet pipe and a water return pipe, shaft heads are installed at both ends of the hollow shaft, and the utility model is characterized in that end covers are fixed at both ends of the roller body, cleaning ports are evenly distributed on the end covers, and sealing pads are installed on the cleaning ports.

[0005] The beneficial effect of the utility model is that the scale or impurities in the roller can be cleaned at any time according to the actual use situation, so as to avoid the impurities blocking the circulation channel of the cooling medium, reduce the purchase cost and improve the quality of the semi-finished rubber parts.
