Description
Technical Field
The invention belongs to the technical field of XPS (extruded polystyrene) foaming special-shaped material processing, and relates to a pre-diffusion oil injection system.
Background
The XPS foamed special-shaped material is mostly used for manufacturing a heat-insulation and decoration integrated plate, and is a novel external wall heat-insulation and decoration integrated plate which is researched and developed by manufacturers in order to meet the national energy-saving building transformation requirements. The board combines the heat-insulating material and the facing material together by a special adhesive compounding method, integrates two functions of heat insulation and decoration of the building enclosure structure with high safety, forms ten series products in three compounding forms according to the requirements of building energy-saving design indexes, building styles, fireproof performance, structural performance, weather resistance and the like, can realize the building energy-saving exterior complete plate type upper wall, and realizes the replacement of the traditional thin-plastered outer wall heat-insulating decoration system.
In the extrusion molding process of the XPS foaming special-shaped material, a layer of lubricating oil is coated on the outer edge surface of the melted foaming raw material before foaming extrusion molding, and the lubricating oil can make the product molding easy, improve the yield and make the product surface smooth and beautiful.
The existing lubricating oil injection coating mode is that a section of runner is added between an extruder and a forming die, and one or more oil injection holes are drilled at the inlet end of the section of runner, because lubricating oil and raw materials are not mutually soluble, when the raw materials flow in the runner, the lubricating oil is naturally driven to be gradually coated on the outer surface of the raw materials.
The greatest defect of the oil injection coating mode is that the thickness of an oil film is not uniform, and when the number of oil injection ports is small, the phenomenon that the surface of a molded product does not have oil at all can even occur. In order to increase the uniformity of oil film coating, the length of the flow channel is usually increased, and in the actual use process, the length of the flow channel is limited due to factors such as heat preservation conditions, site conditions, equipment cost, equipment operation energy consumption and the like.

As a preferable technical scheme of the invention, an outer pipe wall is formed by dividing a conical surface between the front flow pipeline and the rear flow pipeline.
As a preferred technical scheme of the invention, a net-shaped oil pipe is connected between the front flow pipeline and the rear flow pipeline, and the net-shaped oil pipe is formed by combining uniform concave-convex parts on the surfaces of the front flow pipeline and the rear flow pipeline.
As a preferred technical scheme of the invention, the front flow pipeline and the rear flow pipeline are made of PVC high-temperature resistant materials.
As a preferable technical scheme of the invention, a sealing ring is arranged at the joint of the oil injection port and the front flow pipeline.
Has the advantages that: at the position of an oil injection port of an original flow channel, the outer pipe wall of the flow channel is divided into a front flow channel pipe and a rear flow channel pipe by a conical surface, meshed concave-convex parts are uniformly cut on the inner and outer conical surfaces matched with the two parts, and a uniform meshed oil injection pore channel is formed after the two parts are combined, so that lubricating oil is diffused into a uniform oil film before entering the flow channel, and the uniform oil film is formed in advance, so that the condition of non-uniform oil film coating does not exist, the surface of a product is free of oil and is more unlikely to generate, the length of the flow channel can be greatly shortened, the material and the processing cost consumed by manufacturing the flow channel are saved, and corresponding heat insulation materials and consumed energy are also saved simultaneously due to the shortened flow channel.
