Description

Technical Field

[0001] This application relates to the field of oven heating technology, and in particular to a polyurethane-coated wheel rotary oven for production. Background Technology

[0002] Polyurethane-coated wheels are an important industrial product widely used in various mechanical equipment and transportation vehicles. During the production process, polyurethane materials undergo a series of processing steps, including mixing, injection molding, and vulcanization, to obtain the final product. Drying is an indispensable part of the polyurethane-coated wheel production process, directly affecting the product's quality and performance.

[0003] Currently, ovens are used to dry rubber-coated wheels. These ovens mainly consist of a cabinet and multiple heating wires. The heating wires are arranged in the heating chamber inside the cabinet, and heat is generated by electricity to heat the internal space of the cabinet. To improve heating efficiency, through holes are made in the inner wall of the cabinet that communicate with the heating chamber, and fans are installed in the through holes. The purpose is to use the airflow generated by the fans to introduce hot air from the heating chamber into the cabinet, thereby promoting heat distribution.

[0004] However, the fan continuously blows air into a fixed area inside the cabinet, resulting in uneven heat distribution. The polyurethane-coated rollers are heated unevenly during the drying process, which in turn affects the overall heating quality and performance consistency of the product and needs to be improved.
