PE casting machine capable of realizing longitudinal drawing

Abstract

The invention discloses a PE casting machine capable of realizing longitudinal drawing. The PE casting machine comprises a main machine unit, a casting unit, a corona cooling unit and a traction winding unit; the main machine unit comprises a main motor arranged at the upper end of a main machine support; the output end of one side of the main motor is in transmission connection with a transmission gearbox; an extruding machine is mounted at one end of the transmission gearbox; a screw sleeve is mounted at the discharging end of the extruding machine; a hopper is mounted on the upper side of the extruding machine; a continuous net changer is mounted at one end of the screw sleeve; a metering pump is mounted at one end of the continuous net changer; a compact type connecting elbow is arranged at the discharging end of the metering pump. According to the PE casting machine capable of realizing longitudinal drawing, the main extruding structure of the machine is compact, and the whole machine flow is designed in an optimized manner; full-closed-loop control is performed on the extrusion pressure and temperature, so that the stable conveying pressure is guaranteed; the whole machine adopts PLC for centralized control, data are monitored by the aid of a touch screen in real time, and remote maintenance and diagnosis are realized; and a non-stop pulse type automatic net drawing device is adopted, so that the pressure is constant during production, the quality is high, and waste products are few.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a longitudinal stretching PE casting machine. Background technique [0002] Casting machine refers to the special equipment for making cast film. A high-precision electronic ceramic casting machine is used to use alumina as the main raw material for ceramic casting. Firstly, the pulverized powder is mixed with a binder, a plasticizer, a dispersant, and a solvent to make a slurry with a certain viscosity. It flows down from the hopper, and is scraped and coated on the special base tape with a certain thickness by a scraper. After drying and curing, it is peeled off from the top to become the film of the green tape, and then the green tape is punched and cut according to the size and shape of the finished product. Lamination and other processing are made into finished blanks to be sintered. It has the advantages of low cost, high quality, non-toxic, simple production pr...
