Description

Technical Field

[0001] The utility model relates to the field of plastic product processing, in particular to a plastic product extrusion molding device. Background Art

[0002] The so-called plastic is actually a kind of synthetic resin. Its shape is similar to pine resin in natural resin. It is artificially synthesized by chemical means and is called plastic. Plastic is a high-molecular compound polymerized by addition polymerization or condensation polymerization with monomers as raw materials, commonly known as plastic or resin. It can freely change its composition and shape. Nowadays, plastic molding is mostly achieved by extruders. Plastic extruders are also a type of plastic machinery. The extruder head can be divided into right-angle heads and bevel heads according to the direction of the material flow in the head and the angle between the center line of the screw. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die.

[0003] The existing feed ports and barrels are mostly fixed structures, making it difficult to clean and repair the barrel alone. In addition, most of the existing extruders rely on manual feeding, where the raw materials are fed into the feed port and then transferred to the inside of the extruder for melting and extrusion. However, the existing extruders cannot adjust the amount of raw materials fed according to the extrusion rate of the extruder. When the discharge speed of the extruder is reduced, the amount of raw materials fed should be reduced to avoid blockage caused by excessive feeding of raw materials. Utility Model Content
