Abstract

The utility model discloses a kind of single screw extrusion machine, comprise frame, be arranged on the machine barrel in frame, motor and decelerator, be arranged on the screw rod in machine barrel, the output shaft of motor is connected with the power shaft of decelerator, and the output shaft of decelerator is connected with screw rod, and machine barrel is provided with hopper, machine barrel inside is communicated with hopper by the charging aperture be arranged on machine barrel, and the described screw rod thread be positioned near discharging opening is zigzag.The utility model has the advantages that: after utilizing zigzag thread to be smashed by the film in waste material, just easy by waste material thawing, thus reach twice laid.

Description

Single screw extrusion machine
Technical field
The utility model relates to a kind of single screw extrusion machine.
Background technology
Extruder is a kind of conventional equipment in molding machine industry, along with industrial expansion, environmental protection is the problem that a lot of enterprise faces, but common extruder can only use pure material, in the face of waste material has just been had no way, reason is waste material is the difficult things stirred such as film mostly.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of waste material that can use as the single screw extrusion machine of material.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of single screw extrusion machine, comprise frame, be arranged on the machine barrel in frame, motor and decelerator, be arranged on the screw rod in machine barrel, the output shaft of motor is connected with the power shaft of decelerator, the output shaft of decelerator is connected with screw rod, machine barrel is provided with hopper, and machine barrel inside is communicated with hopper by the charging aperture be arranged on machine barrel, and the described screw rod thread be positioned near discharging opening is zigzag.
Described charging aperture is rectangle, and the projection on charging aperture vertical direction is positioned at the side of pitch line.
Described charging aperture is that chamfer is trapezoidal in the cross section of machine barrel radial direction, and the hypotenuse of right-angled trapezium is near the center line of machine barrel.
The position described machine tube inner wall being positioned at screw rod thread indentation is provided with one section of helicla flute, and spiral fluted rotation direction is identical with the thread rotation direction of screw rod.
Described machine barrel outer wall is covered with heater.
The beneficial effects of the utility model are: after utilizing zigzag thread to be smashed by the film in waste material, just easy by waste material thawing, thus reach twice laid.
Accompanying drawing explanation
Fig. 1 is the utility model single screw extrusion machine structure chart;
Fig. 2 is A-A profile in Fig. 1.
In figure: 1, frame, 2, machine barrel, 3, motor, 4, decelerator, 5, screw rod, 6, hopper, 7, charging aperture, 8, zigzag thread, 9, helicla flute, 10, heater.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As depicted in figs. 1 and 2, single screw extrusion machine described in the utility model, comprise frame 1, be arranged on the machine barrel 2 in frame 1, motor 3 and decelerator 4, be arranged on the screw rod 5 in machine barrel 2, the output shaft of motor 3 is connected with the power shaft of decelerator 4, the output shaft of decelerator 4 is connected with screw rod 5, machine barrel 2 is provided with hopper 6, machine barrel 2 inside is communicated with hopper 6 by the charging aperture 7 be arranged on machine barrel 2, and described screw rod 5 thread be positioned near discharging opening 7 is zigzag.Such waste material is smashed by the zigzag thread 8 of screw rod 5 once entering machine barrel 2.In order to make material enter machine barrel 2 faster and smash, described charging aperture 7 is rectangle, and the projection on charging aperture 7 vertical direction is positioned at the side of screw rod 5 center line.In order to improve entering of waste material further, described charging aperture 7 is that chamfer is trapezoidal in the cross section of machine barrel 2 radial direction, and the hypotenuse of right-angled trapezium is near the center line of machine barrel 2.Such waste material on the hypotenuse falling machine barrel 2 after, can rotate along the rotation direction of screw rod 5 faster, thus improve smash efficiency.In order to prevent waste material from skidding in machine barrel 2, efficiency is smashed in impact, and the position described machine barrel 2 inwall being positioned at screw rod 6 zigzag thread 8 is provided with one section of helicla flute 9, and the rotation direction of helicla flute 9 is identical or staggered or mutually oblique with the thread rotation direction of screw rod 6.For improving the melting speed of waste material, described machine barrel 2 outer wall is covered with heater 10.The utility model has the advantages that: after utilizing zigzag thread to be smashed by the film in waste material, just easy by waste material thawing, thus reach twice laid.
