Description

Technical Field

[0001] The utility model relates to the technical field of rubber primary processing, in particular to a production line layout for continuous drying of sheet-shaped natural rubber. Background Art

[0002] Natural rubber is divided into smoked sheet rubber, standard rubber, crepe rubber and latex according to the manufacturing process and appearance. Smoked sheet rubber is the most representative variety of natural rubber. It was once the variety with the largest consumption and the widest application. Its main use is in the production and manufacturing of rubber tires, cables and conveyor belts. Its production process is mainly to make smoked rubber sheets (RSS3) after filtering, acid coagulation, sheet pressing, drying and smoking. Crepe rubber is mainly made of latex clots or mixed rubber as raw materials, which are washed, pressed and refined into rubber with wrinkles on the surface, and dried naturally or with hot air. Crepe rubber is divided into three types according to the appearance, chemical composition and physical and mechanical properties. The quality is assessed, including white crepe sheets, brown crepe sheets and black crepe sheets. Each type is divided into several grades, and there are thin sheets and thick sheets.

[0003] At present, in the drying process of sheet rubber, due to the uneven skills of workers, the baking process is not properly supervised and the firepower is not well controlled, resulting in the product being not baked well, and the residual moisture causing the film to bubble and become raw, which in turn causes mold and other problems. Production practice shows that in the traditional production process, the qualified rate of finished products of smoked sheet rubber is about 75%, and the qualified rate of grades above RSS3 is about 50%. At the same time, due to the low degree of automation in the natural rubber production process, a large amount of manual labor is required to transport and control materials throughout the production process.

[0004] Therefore, in order to solve the problems of low automation and low yield of the existing flaky natural rubber production process, the inability to timely monitor and control the status of each production equipment during the production process, high manual operation intensity and low production efficiency, it is necessary to develop a method for continuous drying of flaky natural rubber and a production line layout.
