A mixing and extruding device for raw materials for sealing ring production

Abstract

The invention provides a seal ring production raw material mixing and extruding device and belongs to the technical field of seal ring production. The seal ring production raw material mixing and extruding device comprises a charging barrel. A partition plate is arranged in the charging barrel, a material mixing area is arranged above partition plate, a heating area is arranged below the partitionplate, a stirring assembly is arranged in the material mixing area, a heating assembly is arranged on the inner wall of the heating area, and an extruding assembly is arranged at the bottom of the heating area. The stirring assembly comprises a vertically arranged driving shaft and a plurality of stirring columns which are rotatably mounted on the side wall of the driving shaft and extend horizontally. The upper end of the driving shaft extends outside the charging barrel and is fixedly connected to a motor. A plurality of stirring rods are arranged on the side walls of the stirring columns.The seal ring production raw material mixing and extruding device provided by the embodiment has the advantages of good raw material mixing effect and high uniform mixing effect. The stirring columnsand the stirring rods rotate alternately forward and backward as a plurality of groups of first tooth sheets and second tooth sheet are engaged intermittently and alternately to stir raw materials from different directions, so that the uniform mixing effect of the raw materials is improved.

Description

technical field [0001] The invention belongs to the technical field of seal ring production, in particular to a raw material mixing and extrusion device for seal ring production. Background technique [0002] Sealing rings are mostly made of rubber materials. In the production of sealing rings, a rubber extruder is required to extrude molten rubber raw materials for preliminary molding. Rubber extruder is a basic equipment in the rubber industry and one of the key equipment that affects product quality. [0003] In addition to rubber, the composition of the sealing ring also contains more auxiliary materials for improving the quality of the sealing ring. When producing the sealing ring, it is necessary to fully mix the rubber raw materials and auxiliary materials. In the prior art, the rubber raw materials and auxiliary materials are usually mixed according to a certain The ratio is put into the mixing barrel and stirred by the stirring equipment, but this mixing method has...

Problems solved by technology

[0003] In addition to rubber, the composition of the sealing ring also contains more auxiliary materials for improving the quality of the sealing ring. When producing the sealing ring, it is necessary to fully mix the rubber raw materials and auxiliary materials. In the prior art, the rubber raw materials and auxiliary materials are usually mixed according to a certain The ratio is put into the mixing barrel and stirred by the stirring equipment, but this mixing method has certain disadvantages. Due to the existing mixing equipment, the stirring direction is relatively single, and it is necessary to mix the raw materials and auxiliary materials evenly. It takes a long time, and the uniformity between raw materials and auxiliary materials cannot be guaranteed
