Abstract
The invention relates to a plasticizing extrusion device provided with the air cooling filtering function. The plasticizing extrusion device comprises a feeding hopper, a machine barrel, a screw rod and a heater. A motor, a reducer, an extrusion die head and the screw rod are coaxially installed in the machine barrel. One end of the screw rod in the machine barrel is connected with the motor through the reducer, and the extrusion die head is installed at the other end of the screw rod of the machine barrel. A front-arranged heating stock bin is installed on the upper portion of the feeding hopper. An insulating layer is installed on the feeding hopper wall. A filter is installed between the front-arranged heating stock bin and the feeding hopper. The heater is divided into a first-level heater, a second-level heater and a third-level heater. The first-level heater, the second-level heater and the third-level heater are sequentially arranged on the machine barrel from the side of the feeding hopper to the side of the die head. An air cooler is installed on the first-level heater, the second-level heater and the third-level heater. The plasticizing extrusion device is simple in structure, scientific and reasonable in design, and capable of effectively reducing energy consumption, shortening the starting time and improving the production efficiency.
Description
Technical field
The invention belongs to extrusion blow-molded field, especially a kind of plasticizing extrusion device with air-cooled filtering function.
Background technology
Along with rapid development of economy, plastic package material uses more and more extensive, the such as plastic bottle of filling milk, in the production process of this plastic bottle, plastic master batch is poured hollow extrusion blowing formation machine into and is carried out forming processes, in molding process, first plastic master batch will plastify and extrude, form intermediate products, existing plasticizing extrusion device comprises feed hopper, machine barrel, screw rod, motor and extrude with die head, screw coaxial to be arranged in machine barrel and to be driven by the motor being arranged on machine barrel one end, the other end of machine barrel is installed and is extruded with die head, feed hopper is installed above machine barrel, the outer wall of machine barrel is set with heater, be melt into rheid state to make plastic master batch to enter die head and carry out being extruded as intermediate products, because heater installs indirect master batch at machine barrel outer wall, so power consumption is large, time is long, reduce production efficiency, when shutting down, machine barrel and screw rod can not cool having certain influence equipment life fast in addition, sometimes some impurity of people are mixed in addition in plastic master batch, certain influence is had to quality of finished.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of plasticizing extrusion device with air-cooled filtering function is provided, this plasticizing extrusion device structure is simple, design science rationally, effectively can reduce power consumption, shortening start-up time, improve production efficiency, improve the quality of products, improve service life.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of plasticizing extrusion device with air-cooled filtering function, comprise feed hopper, machine barrel, screw rod, heater, motor, decelerator and extrusion die, screw coaxial is arranged in machine barrel, screw rod one end in machine barrel connects motor by decelerator, the machine barrel of the screw rod other end installs extrusion die, feed hopper is arranged on machine barrel, mounting heater on machine barrel, it installs front-mounted heating feed bin on feed hopper top, charging headwall installs heat-insulation layer, between front-mounted heating feed bin and feed hopper, filter is installed, heater is divided into primary heater, second level heater and third level heater, to the machine barrel of die head side, primary heater is arranged successively from feed hopper side, second level heater and third level heater, at primary heater, second level heater and third level heater air-cooler is installed above.
And described motor is frequency control motor.
And, described machine barrel is provided with temperature sensor.
Advantage of the present invention and beneficial effect are:
Originally there is the plasticizing extrusion device of air-cooled filtering function, comprise feed hopper, machine barrel, screw rod, heater, motor, decelerator and extrusion die, screw coaxial is arranged in machine barrel, screw rod one end in machine barrel connects motor by decelerator, the machine barrel of the screw rod other end installs extrusion die, feed hopper is arranged on machine barrel, mounting heater on machine barrel, it installs front-mounted heating feed bin on feed hopper top, charging headwall installs heat-insulation layer, between front-mounted heating feed bin and feed hopper, filter is installed, heater is divided into primary heater, second level heater and third level heater, to the machine barrel of die head side, primary heater is arranged successively from feed hopper side, second level heater and third level heater, at primary heater, second level heater and third level heater air-cooler is installed above, structure of the present invention is simple, design science is reasonable, effectively can reduce power consumption, start-up time shortens, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of plasticizing extrusion device with air-cooled filtering function, comprise feed hopper 4, machine barrel 10, screw rod 8, heater, motor 1, decelerator 14 and extrusion die 13, screw coaxial is arranged in machine barrel, screw rod one end in machine barrel connects motor by decelerator, the machine barrel of the screw rod other end installs extrusion die, feed hopper is arranged on machine barrel, mounting heater on machine barrel, it installs front-mounted heating feed bin 3 on feed hopper top, charging headwall is installed heat-insulation layer 5, filter 2 is installed between front-mounted heating feed bin and feed hopper, heater is divided into primary heater 6, second level heater 7 and third level heater 12, to the machine barrel of die head side, primary heater is arranged successively from feed hopper side, second level heater and third level heater, at primary heater, second level heater and third level heater air-cooler 9 is installed above.Motor is frequency control motor.Machine barrel is provided with temperature sensor 11, extrusion temperature is accurately controlled.
Frequency control motor of the present invention passes to screw rod by decelerator, under the effect of rotary screw, the rubbing action of machine tube inner wall and screw surface, plastic master batch conveying and the compacting of screw rod will be entered from feed hopper, plastic master batch and through preheating in front-mounted heating feed bin, transporting velocity can improve than for the speed through preheating, becoming viscous state through primary heater, second level heater and third level heater plastic master batch, level pressure, quantitatively and constant temperature enter extrusion die.
