Description

Utilize liquid CO 2Make the make-up machine of extrusion molding type foamed plastics
Technical field
The utility model belongs to the improvement of foam type sheet material extruding machine structure, particularly utilizes liquid CO 2Make the make-up machine of extrusion molding type foamed plastics.
Background technology
The design feature of the manufacturing process of existing relevant foaming plate or sheet material: can freon or F22 etc. are added nitrogen supercharging, directly squeeze into to produce in the main frame body by plunger displacement pump and stir with the abundant melting of material, being advanced into the mould ground by screw rod extrudes wink and asks foaming, make sheet material through shaping, its shortcoming is: (1) price height; (2) not environmental protection damages the ozone layer.
The utility model content
The purpose of this utility model is to provide a kind of liquid CO that utilizes 2Make the make-up machine of extrusion molding type foamed plastics, go for utilizing liquid CO 2Produce foamed plastic sheet material or sheet material as environment-friendly foaming agent extruding, the foamed plastic sheet material of its output or sheet material price are low cheap, and environmental protection does not damage the ozone layer, and has improved the fire resistance of foamed plastic sheet material.
Order of the present utility model is achieved in that a kind of liquid CO that utilizes 2Make the make-up machine of extrusion molding type foamed plastics, comprise the heater that is arranged in the main frame, extrusion dies and with the blowing agent transfer pipeline, the blowing agent transfer pipeline is communicated with the cooperation of conveying pipeline road, the conveying pipeline road is communicated with the die cavity of extrusion dies, liquid CO 2Storage tank is connected with the cooling device entrance point by check-valves, liquid-transport pipe-line, the cooling device port of export is connected with blowing agent transfer pipeline charging aperture by infusion pump, flow sensor, the liquid-transport pipe-line that is communicated with infusion pump and blowing agent transfer pipeline also is communicated with energy storage canister by lateral, is being communicated with check valve being connected in series on the pipeline between flow sensor and the blowing agent transfer pipeline charging aperture; Infusion pump and flow sensor are connected by cable and data on flows controller respectively.
Technological difficulties of the present utility model are liquid CO 2Be difficult to stable, accurate measurement ground injection extruding machine body, the correlative flow data are difficult to control, cause reasonably to reach the purpose that makes sheet material inside be full of fixing carbon dioxide bubble, pass through CO 2Liquid CO 2The aux. pressure that the pressure of storage tank reaches at energy storage canister makes liquid CO 2Entering the cryogenic piping (the temperature setting of pipeline is not less than-35 ℃) of refrigeration system, is for fear of liquid CO through the purpose of apparatus for supercooling K cryogenic treatment 2Gasification (pressure 35MPa); Because liquid CO 2HIGH PRESSURE TREATMENT has guaranteed liquid CO after having taked first low temperature 2Do not gasify or form dry ice, had good flowability, in the time of again by pipeline, through (that the effect of energy storage canister is mainly played is stable in the extruding machine body, inject liquid CO continuously with the energy storage canister current stabilization effect of pipeline connection 2), under the control of data on flows controller, make infusion pump subsequently with CO 2Stably, accurate measurement pass through unidirectional injection valve injection body (body pressure 15MPa-20MPa), make raw material cooperate to mix mutually and make foam board or the sheet material that inside is full of the qualified moulding of carbon dioxide bubble by die head with blowing agent.According to the specification requirement of sheet material or sheet material products to CO 2The injection rate and temperature, the pressure data of main frame adjust accordingly to reach and produce qualified sheet material or sheet material.Therefore, the utility model goes for utilizing liquid CO 2As foamed plastic sheet material or the sheet material that environment-friendly foaming agent extruding is produced, foamed plastic sheet material that it is made or sheet material price are low cheap, and environmental protection does not damage the ozone layer, and has improved the fire resistance of foamed plastic sheet material.
