Description
Technical field
The utility model belongs to technical field of mechanical equipment, is specifically related to a kind of plastic extruder.
Background technology
In use, inside screw pressure is suddenly big or suddenly small, extremely unstable for existing plastic extruder, can not regulate extruded velocity at any time according to the size of internal pressure, and in machine barrel, heating is uneven, the plastic shaping weak effect extruded.
Summary of the invention
The purpose of this utility model is for above problem, provides a kind of plastic extruder, and structure is simple, maintains easily, and can realize speed and regulate, reduce the impact injury to equipment when producing according to inside screw pressure size, extension device service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of plastic extruder, comprise machine barrel, machine barrel inside is cavity design, and screw rod is provided with in cavity, the top of machine barrel one end is provided with hopper, between hopper and machine barrel, movable valve is installed, the other end of machine barrel is provided with extrusion die, described screw rod is connected with drive unit, and drive unit adopts 220kw variable-frequency motor, is provided with heat-insulation layer outside described machine barrel, the barrel of machine barrel is double-decker, and inside is provided with heating element heater.
Described heating element heater is solenoid or resistance wire, is evenly distributed in the barrel of machine barrel.Adopt the Electromagnetic Heating heating-up time greatly to shorten, and heating-up temperature is accurate, the efficiency of heating surface is high, and the plastic shaping extruded is good.
Described drive unit comprises the variable-frequency motor, belt and the decelerator that connect successively, and screw rod is connected with decelerator.Owing to adopting variable-frequency motor, dragging load that can be stable, service life of equipment is long, by the setting of reductor, like the screw rod pressure stability of bearing, and can adjusting rotary speed as required, and then the extruded velocity of control plastics.
Described hopper is also provided with shaking device and agitating device.Promote powder machine particular plastics and mixing by shaking and stirring, cut can be smooth the machine barrel inside that enters into heat.
Also dust cap is installed above described hopper, entering of dust can be avoided, improve the quality of product.
The utility model adopts variable-frequency motor, is convenient to the rotating speed of adjusting screw(rod), has reduced the impact injury to equipment, on the other hand, can also save energy consumption.Meanwhile, multiple optimization is carried out to the structure of hopper, can the charging of stable and uniform, improve the quality of extrusion plastic, finally improve the quality of the composited aluminum and plastic decking of production.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Further illustrate the utility model below in conjunction with embodiment, but the claimed scope of the utility model is not limited to the scope of embodiment statement.
As shown in Figure 1, a kind of plastic extruder, comprises machine barrel 1, machine barrel 1 inside is cavity design, and in cavity, being provided with screw rod 2, the top of machine barrel 1 one end is provided with hopper 3, is provided with movable valve 4 between hopper and machine barrel 1, the other end of machine barrel 1 is provided with extrusion die 5, described screw rod 2 is connected with drive unit 6, and drive unit adopts 220kw variable-frequency motor, is provided with heat-insulation layer outside described machine barrel 1, the barrel of machine barrel 1 is double-decker, and inside is provided with heating element heater.
In preferred scheme, described heating element heater is solenoid or resistance wire, is evenly distributed in the barrel of machine barrel 1.
In preferred scheme, described drive unit 6 comprises the variable-frequency motor, belt and the decelerator that connect successively, and screw rod 2 is connected with decelerator.
Further, described hopper is also provided with shaking device and agitating device.
Further, also dust cap is installed above described hopper.
During use, open the heating element heater of machine barrel 1, preheating is carried out to machine barrel and screw rod, then open drive unit 6, think to add plastic raw materials in hopper, by machine barrel by plastic molting, and moved ahead by the rotation propelling fluid plastics of screw rod, after extrusion die sizing, carry out the process of subsequent step.
