Abstract
The utility model is related to a kind of nozzle cooling systems of plastic pipe extruder, it is characterised in that：Extruder nozzle, circulating pump, liquid reserve tank, cooler bin and babinet adjusting bracket；By using height-adjustable cooler bin in the utility model, the coolant liquid of different pressures is used according to the thermoplastic tube of unlike material, change coolant liquid to the height of extruder nozzle by flexibly changing modularization overflow plate or regulating box adjusting bracket to control pressure size, it realizes that the thermoplastic tube of unlike material uses the regulative mode of disparate modules, avoids the underproof problem of product caused by pressure is unstable.
Description
Technical field
The utility model is related to thermoplastic tube production field more particularly to a kind of nozzle cooling systems of plastic pipe extruder.
Background technology
Plastic grain is heated by extrusion molding by extruder in general thermoplastic tube production, it is general in the cold of extruder
But the precooling system of thermoplastic tube is provided at nozzle, general precooling system in the outlet of extruder by opening up connection
The cold of coolant liquid removes mouth so that coolant liquid is looped around on the outer wall of thermoplastic tube and is precooled when thermoplastic tube squeezes out, but past
It is improper toward the pressure control due to coolant liquid, cause just to go out in the thermoplastic tube of extruder and many cooling air marks occur, affects heat
Mould the appearance and product quality of pipe.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of nozzle cooling systems of plastic pipe extruder, can solve
Certainly general thermoplastic tube leads to the problem of many air marks when being precooled by extruder extrusion.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of nozzle cooling of plastic pipe extruder
System, innovative point are：Extruder nozzle, circulating pump, liquid reserve tank, cooler bin and babinet adjusting bracket；
It is joined end to end by cooling pipe between the extruder nozzle, liquid reserve tank and cooler bin；The liquid reserve tank with it is cold
But circulating pump is provided between case, the coolant pump in liquid reserve tank is sent in cooler bin by the circulating pump, on the cooler bin
It is provided with overflow plate；It is provided with filter in the liquid reserve tank；The cooler bin is arranged on babinet adjusting bracket, the cooler bin
Adjusting can be moved up and down on babinet adjusting bracket；
The height that the liquid level distance of the cooler bin squeezes out nozzle is denoted as H, the ranging from 1.0m-1.5m of the H；It is described cold
But the overflow plate on case is modularization plate, and the overflow plate, which can carry out replacing, ensure that the liquid level in cooler bin goes out to cooler bin
The pressure modularization of liquid mouth.
Further, cooling liquid inlet and cooling liquid outlet are respectively arranged on the extruder nozzle；The coolant liquid
Import is connected to by cooling pipe on cooler bin, and the cooling liquid outlet is connected to by cooling pipe on liquid reserve tank；It is described
The aperture of cooling liquid inlet is identical as the aperture of cooling pipe.
Further, it is provided with liquid level sensor on the inner wall of the cooler bin.
Further, solenoid electric valve, the liquid level sensor and the electromagnetism on circulating pump are provided on the circulating pump
Control valve signal intercommunication.
The utility model has the advantage of：
1）By using height-adjustable cooler bin in the utility model, according to the thermoplastic tube of unlike material using different
The coolant liquid of pressure changes coolant liquid to extruder pipe by flexibly changing modularization overflow plate or regulating box adjusting bracket
Mouthful height to control pressure size, realize unlike material thermoplastic tube use disparate modules regulative mode, avoid because
Pressure is unstable to cause the underproof problem of product.
