Novel plastic extruding machine with high product forming rate for manufacturing PVC (Polyvinyl Chloride) pipeline and method

Abstract

The invention discloses a novel high-product-forming-rate plastic extruding machine for PVC pipeline manufacturing and a method, and relates to the field of pipeline extrusion molding. The novel high-product-forming-rate plastic extruding machine for PVC pipeline manufacturing comprises a base, wherein the top side of the base is fixedly provided with an extruding machine barrel through a supporting table, one side of the extruding machine barrel is fixedly provided with an extruding pipe die, and a driving motor is fixedly mounted on the top side of the base through a machine base. The extrusion machine is reasonable in structure. When a driving motor is started, an extrusion auger is driven to rotate for extrusion molding, and meanwhile, a plurality of first stirring rods and a plurality of second stirring rods are driven to rotate reversely to stir and mix raw materials uniformly, anti-blocking treatment is conducted on a filter screen, so that the situation that part of the raw materials are not completely molten but directly extruded is avoided, and therefore, the product quality is ensured; when a cooling motor is started, cooling fan blades can be driven to rotate and move circumferentially, uniform air cooling heat dissipation can be conducted on the extrusion pipe die, raw materials can be uniformly cooled and formed in the extrusion pipe die, so that the forming effect is good, and the forming rate is high.

Description

technical field [0001] The invention relates to the field of pipe extrusion, in particular to a novel extruder and method with high forming rate for PVC pipe manufacture. Background technique [0002] The extruder is an important plastic machine, and the production and manufacture of most plastic products can be realized by extrusion molding. When making PVC pipes, the raw materials are first put into the machine and heated and melted, and then the molten raw materials are extruded to finally obtain PVC pipes. [0003] Existing extruders for PVC pipe manufacturing generally melt raw materials directly when melting raw materials. Various raw materials are not mixed evenly, and it is easy to cause some raw materials to be directly extruded without being completely melted, which affects the quality of the finished product. At the same time, most of the existing extruders are naturally cooled in the extrusion molding of pipes, and the pipes are prone to deformation under high t...

Problems solved by technology

[0003] Existing extruders for PVC pipe manufacturing generally melt raw materials directly when melting raw materials. Various raw materials are not mixed evenly, and it is easy to cause some raw materials to be directly extruded without being completely melted, which affects the quality of the finished product. At the same time, most of the existing extruders are naturally cooled in the extrusion molding of pipes, and the pipes are prone to deformation under high temperature conditions, and the forming rate is relatively poor. Therefore, this application discloses a product with a forming rate High new extruder to meet people's needs
