Low-permeability fuel pipe extrusion production equipment

Abstract

The invention relates to low-permeability fuel pipe extrusion production equipment. The low-permeability fuel pipe extrusion production equipment comprises a core release machine, a front traction machine, a composite extruder, a fluoroplastic extruder, an air cooling device, a wrapping extruder, a cooling tank and a rear traction machine, wherein the front traction machine, the composite extruder, the fluoroplastic extruder, the air cooling device, the wrapping extruder, the cooling tank and the rear traction machine are sequentially arranged along a core conveying path. The fluoroplastic extruder comprises an extruder body, a servo motor, a speed reducer, a feeding barrel mounted on the extruder body, a screw, a cover mounted on the extruder body, an extrusion barrel penetrating throughthe cover, multiple heating rings mounted on the extrusion barrel in a sleeving manner and an extrusion head connected to an outlet of the extrusion barrel. A feeding opening is formed in the feedingbarrel, one end of the feeding barrel is connected to the extrusion barrel, and the other end of the feeding barrel is connected to the speed reducer. The screw is located in an inner cavity formed bythe extrusion barrel and the feeding barrel together. All the heating rings are located in the cover. A heat insulation plate is arranged between every two adjacent heating rings. Fuel pipes producedthrough the production equipment meet the requirements of the CN6 standard and standards before the CN6 standard, and the production equipment belongs to the techncialfield of fuel pipe production.

Description

technical field [0001] The invention relates to the technical field of fuel pipe production, in particular to low-permeability fuel pipe extrusion production equipment. Background technique [0002] With the continuous strengthening of the country's environmental protection, the country has issued the National Sixth Stage Motor Vehicle Pollutant Emission Standards, hereinafter referred to as the National Sixth Standard. In order to meet the requirements of the National Sixth Standard, it is necessary to increase the requirements for vehicle emissions. The fuel pipe is an important part of it. Good-quality fuel pipes can greatly reduce vehicle pollution emissions. The current production of fuel pipes does not meet the emission requirements of the National Sixth Standard. Contents of the invention [0003] In view of the technical problems existing in the prior art, the object of the present invention is to provide a low-permeability fuel pipe extrusion production equipment,...
