Abstract
This utility model relates to a kind of full-automatic screw extruder, the barrel including support, being arranged on described support and the hopper connected with described barrel and motor, it is provided with screw rod in described barrel, described barrel is divided into several sub-material cylinders, each sub-material cylinder constitutes a cooling water system by water inlet and outlet, hopper is provided with charging absorption pump, by being equipped with cooling water system and cyclic feeding system, keeps the constant temperature of screw machine and can reduce production cost.
Description
Technical field
This utility model relates to the extrusion molding machine of a kind of film blowing device, specifically a kind of full-automatic screw extruder.
Background technology
When cast-sheet start produces, first with charging absorption pump suction in hopper, hopper is delivered to pressing die head extrusion sheet by screw extruder after powder material and particulate material mix homogeneously.
There is following Railway Project in traditional extruder: hopper mix stages, compound due to granular materials Yu powder body material, hopper is sucked by charging absorption pump, work is continuous, some raw material can the most filled or powder body material fly upward to the pump housing of charging absorption pump, affect the operating of pump, and also have waste of raw materials, improve production cost.Furthermore, the plastic pellet in raw material is sheared in twin screw, friction can produce heat, and too high or too low temperature can make compound really up to the mark or excessively flow when extruder discharging, is unfavorable for follow-up extrusion sheet.
Utility model content
For the problems referred to above, this utility model provides a kind of full-automatic screw extruder, and hopper arranges a water cooling system by using a cyclic feeding system to save in production cost, and work, maintains the constant temperature of screw extruder.
This utility model is achieved through the following technical solutions: a kind of full-automatic screw extruder, including support, it is arranged on the barrel on described support and the hopper connected with described barrel, and motor, it is provided with screw rod in described barrel, described barrel is divided into several sub-material cylinders, each sub-material cylinder is equipped with water inlet and outlet, described water inlet connects cooling-water machine by conveyance conduit, described outlet connects cooling-water machine by conveyance conduit, constitute a water cooling system, it is provided with temperature sensor in described barrel, described temperature sensor data connects cooling-water machine, described cooling-water machine, motor data connects a controller.
Temperature sensor can detect the temperature that screw extruder is real-time, and when temperature exceedes setting value, controller controls cooling-water machine conveying cooling water, and screw machine is carried out cooling down.If cooling water inflow big cooling efficiency is high, when temperature is less than setting value, then can close cooling-water machine and stop the cooling water that conveying is new.
Preferably, described hopper be arranged over charging absorption pump, the entrance of charging absorption pump is by connecting flexible pipe suction in feed bin, described charging absorption pump is provided with an outlet poly-dirt cabinet, described poly-dirt cabinet is connected to feed bin by conveying pipeline, and the bottom of described poly-dirt cabinet is provided with pressure transducer, and described pressure sensor data connects controller, control valve, described control valve data cube computation controller it is provided with between described poly-dirt cabinet and feed bin.
When charging absorption pump is during hopper suction, if there have raw material surplus to have not enough time to from hopper to be processed, or the powder flown upward departs from particulate material, i.e. can enter in poly-dirt cabinet, will not adhere to in the pump housing of charging absorption pump, when the pressure transducer in poly-dirt cabinet exceedes setting value, and the material in poly-dirt cabinet is delivered in feed bin by controller opening controlling valve again, continue to mix with particulate material in suction hopper, constitute a fill cycles system.
This utility model takes above-mentioned corrective measure, and its beneficial effect is notable: by screw extruder is equipped with cooling water system and cyclic feeding system, keeps the constant temperature of screw extruder, reduces production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment 1；
In figure, 1 is support, and 2 is controller, and 3 is hopper, and 4 is barrel, and 5 is cooling-water machine, and 6 is poly-dirt cabinet, and 7 is charging absorption pump, and 8 is control valve, and 9 is feed bin, and 10 is flexible pipe.
Detailed description of the invention
