batte continuous screen changer system

The continuous screen changer extrusion system includes screw, cylinder, Hopper, head, and mould. The plastic is moulded into a uniform melt through the extrusion system.

(1) Screw: is the main part of the continuous screen changer extruder, which is directly related to the application range and productivity of the extruder, made of high strength corrosion resistant alloy steel.

(2) Machine cylinder: is a metal cylinder, generally made of heat resistant, high compressive strength, strong wear-resistant, corrosion-resistant alloy steel or alloy steel lining composite steel tube. The machine barrel and screw cooperate to realize the crush, soften, melt, plasticize, exhaust and compaction of plastic, and continuous uniform delivery of rubber to the molding system. Generally, the length of the cylinder is 15 to 30 times its diameter, so that the plastic is fully heated and plasticized.

(3) continuous screen changer Hopper: the bottom of the hopper is provided with a truncation device to adjust and cut the flow of the Hopper and the side of the hopper is provided with a viewing hole and calibration.

(4) continuous screen changer Machine head and molds: The continuous screen changer head consists of an alloy steel inner sleeve and a carbon steel jacket. The function of the head is to transform the rotating plastic melt into a parallel straight motion, to be uniformly and smoothly introduced into the mould and to give the plastic the necessary molding pressure. The plastic is plasticized and compacted in the cylinder, and through a porous filter plate, through a certain flow path into the head of the head and neck of the head molding mould, the core mould sleeve fits in properly, forming a ring void with decreasing cross section, making the plastic melt form a continuous dense tubular overlay around the core line. In order to ensure that the plastic flow line in the head of the machine is reasonable, eliminate the accumulation of plastic dead angle, often installed shunt sleeve, in order to eliminate the pressure fluctuation of plastic extruding, there are also set equal pressure ring. The head of the machine is also equipped with the die calibration and adjustment device, easy to adjust and adjust the core and die sleeve of the concentric.
