Abstract
The invention discloses a push-pull double-screw extruder, which comprises a fixed base, a sliding base, a motor and a speed reducer. The push-pull double-screw extruder is characterized in that: a cavity is formed at one end above the fixed base; a push-pull guide rail is arranged in the cavity and is controlled to perform rectilinear motion by a hydraulic system; the sliding base which can slide linearly is arranged at the other end above the fixed base; the sliding base is connected with the push-pull guide rail; the motor and the speed reducer are arranged above the cavity; the output shaft of the motor is connected with the input shaft of the speed reducer through a shaft coupling; a screw tube is arranged above the sliding base; double screws are arranged in the screw tube; and a feeding hopper is arranged on the screw tube. The push-pull double-screw extruder solves the problems of low production efficiency, poor plastic granulation quality and troubles in arranging, maintaining and replacing screws in a single-screw extruder in the prior art, and the invention provides the push-pull double-screw extruder which can save production cost, remarkably improve the production efficiency and is easy to maintain and replace.
Description
Technical field
The present invention relates to a kind of plastic extruder, particularly relate to a kind of push-pull double-screw extruder.
Background technology
At present, the single screw extrusion machine that is used for plastic granulating, its structure generally includes: frame, the power set that frame is provided with a barrel and is made up of motor and speed reducer, barrel is provided with heater, be provided with screw rod in the barrel, an end of screw rod is connected with the output shaft of reductor, and the power shaft of reductor is connected with the output shaft of motor.The operation principle of above-mentioned extruder is: waste or used plastics enters into barrel from feeding hopper, plastifies and homogenizing under the promotion of screw rod then, extrudes needed plastic pellet at last.There is following shortcoming in the extruder of said structure: 1, single screw extrusion machine fricative heat of when work is bigger, and the suffered shearing of material is also inhomogeneous, and conveying capacity can be less, and extrusion capacity is lower, and speed of production is slow, and efficient is low; 2, material time of staying in barrel short, mix inhomogeneous, the plastic pellet inferior quality of producing; 3, can easily not mount and dismount maintenance, the compound mode of changing screw rod and screw flight comparatively bothers, and can not remove the leftover materials that reach machine barrel inside above the screwing element fast,
Summary of the invention
Low in order to solve in the prior art single screw extrusion machine production efficiency, the problem that screw rod comparatively bothers is changed in the installation and maintenance simultaneously of plastic granulating inferior quality, the invention provides a kind of saving production cost, significantly improve production efficiency, for ease of maintenaince the push-pull double-screw extruder of Geng Huaning.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of push-pull double-screw extruder, comprise firm banking, sliding bottom, motor, reductor, it is characterized in that: also comprise barrel and twin-screw, an end is provided with cavity above firm banking, in cavity, be provided with sliding rail, and sliding rail is by the HYDRAULIC CONTROL SYSTEM rectilinear motion, above firm banking the other end be provided with can linear slide sliding bottom, sliding bottom is connected with sliding rail; Above cavity, be provided with motor and reductor, the output shaft of described motor is connected by shaft coupling with the power shaft of reductor, above sliding bottom, be provided with barrel, in barrel, be provided with twin-screw, one end of described twin-screw is connected with speed reducer output shaft by connector, is provided with feeding hopper on barrel.
Aforesaid a kind of push-pull double-screw extruder is characterized in that: described firm banking is provided with line slide rail, and described sliding bottom has linear ramp, and described line slide rail and linear ramp are suitable.
Aforesaid a kind of push-pull double-screw extruder is characterized in that: be provided with the cylindrical shell guard shield in the outside of barrel.
Aforesaid a kind of push-pull double-screw extruder is characterized in that: the type of cooling of described barrel is air-cooled or water-cooled.
The invention has the beneficial effects as follows: the present invention adopts the twin-screw mode, and the feeding characteristic is better, than single screw extrusion machine better mixing, exhaust, reaction and self-cleaning function is arranged.The shearing that fricative heat is less, material is suffered simultaneously is also comparatively even, big, more stable, the high efficiency of extrusion capacity of the conveying capacity of twin-screw, reduced the cost of enterprise, material time of staying in barrel is long in addition, mix, the plastic pellet quality of producing is higher.Sliding bottom of the present invention can linear slide, when not producing, barrel can be separated with reductor, and the screw rod of being convenient to like this in the barrel is changed, and installs and keep in repair more convenient.
Description of drawings
Fig. 1 is view before the push-pull double-screw extruder push-and-pull of the present invention;
Fig. 2 is view after the push-pull double-screw extruder push-and-pull of the present invention.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, push-pull double-screw extruder, comprise firm banking 1, sliding bottom 2, motor 8, shaft coupling 9, reductor 10, barrel 12 and twin-screw 19, an end is provided with cavity 7 above firm banking 1, in cavity 7, be provided with sliding rail 6, and sliding rail 6 is connected with hydraulic system 5, hydraulic system 5 control sliding rails 6 are done rectilinear motion, the other end is provided with sliding bottom 2 above firm banking 1, on firm banking, be provided with line slide rail 4, have linear ramp 3 at sliding bottom 2, line slide rail 4 is suitable with linear ramp 3, makes sliding bottom 2 to slide along line slide rail 4 front and back.Above cavity 7, be provided with motor 8 and reductor 10, the output shaft 16 of described motor 8 is connected by shaft coupling 9 with the power shaft 17 of reductor 10, above sliding bottom 2, pass through to support 14 fixedly connected barrels 12, in barrel 12, be provided with twin-screw 19, one end of described twin-screw 19 is connected with the output shaft 18 of reductor 10 by connector 11, be provided with cylindrical shell guard shield 13 in the outside of barrel 12, on barrel 12, be provided with feeding hopper.The type of cooling of described barrel 12 can be air-cooled or water-cooled, is provided with into return pipe 15 in barrel 12 bottoms, is used for cooling off barrel 12.
