Description

Technical Field

[0001] The utility model relates to the technical field of rubber product production, in particular to a calendering device for producing natural rubber products. Background Art

[0002] Rubber products refer to the production of various rubber products using natural and synthetic rubber as raw materials, including rubber products recycled from waste rubber. Synthetic rubber production has significantly surpassed natural rubber, with styrene-butadiene rubber (SBR) producing the largest output. Calendering involves pressing a rubber compound through a calender to form sheets of a specific shape and size. This is why a calender is required. A calender consists of two or more rollers arranged in a specific pattern, which, at a specific temperature, press and stretch rubber or plastic into sheets of a specific thickness and surface shape. It can also coat fiber cords, canvas, or steel cords with rubber.

[0003] Calendering is suitable for making simple sheet and plate products. It is a method of pressing the mixed rubber into a certain shape and size of rubber through a calender. It is called calendering molding. Some rubber products, such as tires, tapes, hoses, etc. The textile fiber materials used must be coated with a thin layer of glue. Coating glue on the fiber is also called gluing or rubbing glue. The gluing process is generally completed on the calender. The fiber material needs to be dried and dipped in glue before calendering. The purpose of drying is to reduce the water content of the fiber material to prevent water evaporation and bubbling, and to increase the temperature of the fiber material to ensure the quality of the calendering process. Dipping is a necessary process before gluing. The purpose is to improve the bonding performance of the fiber material and the rubber.

[0004] In the production process of rubber seals, the rubber raw materials must first be mixed, and then manually transported to the rollers of the calender for sheeting. However, this manual handling method has significant drawbacks: manual handling is not only inefficient but also has high labor costs; the mixed rubber raw materials are not only heavy but also hot, making it difficult for workers to handle, and are prone to burns during the handling process, resulting in a low work safety factor. Currently, most production processes use manual feeding, but this is labor-intensive, poses certain safety risks to workers, and results in low production efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a calendering device for producing natural rubber products, which can realize the loading of rubber raw materials during calendering and the demoulding operation after calendering and molding.
