what is the composition of die face cutting plastic recycling machine?

Date: 29th Jul, 2017

(1) head and die: die face cutting plastic recycling machine head from the alloy steel sleeve and carbon steel jacket, the machine head with a molding die. The role of the nose is to rotate the plastic melt into a parallel linear motion, uniform and smooth into the mold sleeve, and give the plastic to the necessary molding pressure. Plastic in the barrel of plastic compaction, the porous filter plate along a certain flow through the nose of the nose into the nose forming mold, mold core sleeve with the appropriate cross-section to form a continuous reduction of the annular gap, so that the plastic melt in the A thick, tubular coating is formed around the core. In order to ensure that the plastic channel inside the machine is reasonable, to eliminate the accumulation of plastic dead ends, often placed a shunt sleeve, to eliminate the pressure when the plastic extrusion fluctuations, but also set the pressure ring. The head is also equipped with mold correction and adjustment of the device, easy to adjust and correct the core and die sets of concentricity.

(2) barrel: a metal cylinder, generally with heat, pressure strength is high, durable wear, corrosion-resistant alloy steel or alloy steel alloy made of composite steel pipe. The barrel is screwed with the screw to achieve crushing, softening, melting, plasticizing, venting and compaction of the plastic, and continuously conveying the compound to the forming system. The length of the general barrel is 15 to 30 times its diameter, so that the plastic is fully heated and fully plasticized to the principle.

(3) Hopper: The bottom of the hopper is equipped with a truncation device to adjust and cut the material. The side of the plastic pellet hopper is equipped with a viewing hole and a calibration metering device.

(4) screw: the extruder is the most important components, it is directly related to the scope of application of extruder and productivity, made of high strength corrosion-resistant alloy steel.

The mainframe of die face cutting plastic recycling machine is the extruder, which consists of an extrusion system, a drive system and a heating and cooling system. 1. Extrusion system The extrusion system consists of screws, barrels, hoppers, heads, and molds, which are plasticized into a uniform melt through the extrusion system and are created under pressure.
