Extruder for producing fluorinated silicone rubber hose

Abstract

The invention provides an extruder for producing fluorinated silicone rubber hose. The extruder comprises an extruder body, the top of the extruder body communicates with a premixing box, a driving motor is erected at the top of the premixing box, an output shaft of the driving motor is connected with a premixing shaft, the premixing shaft penetrates through the premixing box and is arranged at the inner bottom of the premixing box, a guide hopper is arranged in the premixing box. The guide hopper communicates with the extruder body. The driving motor is started, the premixing shaft rotates, and spiral stirring blades and stirring blades are driven to rotate, so that materials are fully dispersed, the premixing shaft rotates to drive a driving wheel to rotate, the driving wheel is connected with a driven wheel through a belt, the driven wheel rotates, then a longitudinal shaft rotates, a beating block is driven to rotate and is in contact with a coordination block. An extrusion column drives an extrusion sliding block to move, so that materials are extruded, and meanwhile, the beating block rotates to be away from the coordination block, a reset spring is reset, and continuous extrusion is achieved. Furthermore, stirring, premixing and extruding can be synchronously carried out, and the working efficiency of the extruder is improved.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to an extruder for the production of fluorosilicone rubber hoses. Background technique [0002] Rubber hose is a type of tubular rubber product used to convey gas, liquid, slurry or granular materials. Usually, the rubber hose is composed of an inner rubber layer, an outer rubber layer and an intermediate skeleton layer. The material of the skeleton layer can be synthetic fiber, carbon fiber or steel wire. The inner rubber layer of the rubber hose directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner body of the rubber hose from damage and erosion of the external environment; the skeleton layer is the pressure-bearing layer of the rubber hose, giving the hose body strength and rigidity. At present, in the metallurgical industry, rubber hoses are often used for coal injection and solid particle or gas-solid mixture materials....

Problems solved by technology

[0003] The existing extruder cannot pre-mix the material, and the hose material has poor uniformity, resulting in poor quality of the hose extruded product
