Extruded plastic plate cooling and shaping equipment of screw extruder

Abstract

The invention discloses extruded plastic plate cooling and shaping equipment of a screw extruder, and belongs to the technical field of plastic plate cooling and shaping. The extruded plastic plate cooling and shaping equipment comprises two oppositely arranged mounting plates, an extrusion end of the screw extruder is arranged between the two mounting plates, and two extrusion belts are arranged between the two mounting plates; in the plastic plate extrusion process, the extrusion belt is cooled, so that the extruded plastic plate is indirectly cooled, slow cooling of the plastic plate is facilitated, and the situation that the plastic plate is hardened after being cooled too fast, consequently, extrusion and stretching are difficult, and the production and machining difficulty is increased is avoided; the surface of the extrusion belt is wiped with a lubricant through the first lubricating box, so that when the extrusion belt extrudes the plastic plate, the plastic plate cannot be adhered to the extrusion belt; the cooling mechanism and the lubricating mechanism can change the cooling degree and the lubricating degree according to different thicknesses of extruded plastic plates.

Description

technical field [0001] The invention relates to the technical field of cooling and shaping of plastic plates, in particular to an extruded plastic plate cooling and shaping equipment of a screw extruder. Background technique [0002] Most plastics have a series of advantages such as light weight, chemical stability, no rust, good impact resistance, good transparency and wear resistance, good insulation, good coloring, and low processing cost, so they are widely used in daily life. and industrial production are widely used. Different physical and chemical properties of various plastics can be divided into two types: thermoplastic and thermosetting. The processing technology of thermoplastics is mostly extrusion. [0003] In the prior art, when using a screw extruder to produce plastic sheets, the freshly extruded plastic sheets will be in a high-temperature molten state. Generally, water cooling will be performed after the plastic sheets are extruded to cool the plastic shee...

Problems solved by technology

[0005] The object of the present invention is to provide a cooling and shaping equipment for extruded plastic sheet material of a screw extruder, to solve the above-mentioned background technology. When using a screw extruder to produce plastic sheet material in the prior art, It will be in a high-temperature molten state. Generally, water cooling will be carried out after the plastic sheet is extruded to cool the plastic sheet to a certain extent, and then the plastic sheet will be extruded and stretched by using a constant temperature conveying roller. However, in the process of water cooling, the water is directly Spray on the surface of the plastic sheet, the evaporation of the water will take away more heat, and it is easy to overcool the plastic sheet, resulting in hardening of the plastic sheet, making it difficult to extrude and stretch, and increasing the processing difficulty of the plastic sheet during production.
