Description
Technical field
The utility model discloses a kind of single screw extrusion machines, specially extruder technology field.
Background technology
In field of plastics processing, using machining is squeezed out, single screw extrusion machine is normal for the processing of most of plastics
A kind of extruder, single screw extrusion machine can provide larger torque, be the extruder of large-scale processing factory's favor, existing list
Screw extruder mostly uses greatly external heating device and is heated, and the former material uneven heating inside extruder causes former material to melt
When, mixes uneven, and finished product defect rate is higher, and existing extruder drive noise is larger, causes working environment poor.
Utility model content
The purpose of this utility model is to provide a kind of single screw extrusion machines, mentioned above in the background art existing to solve
There are former material uneven heating inside extruder, the larger problem of drive noise.
To achieve the above object, the utility model provides the following technical solutions：A kind of single screw extrusion machine, including extruder
The outer wall of shell, the extruder shell is installed with three groups of external heating devices, the top left part of the extruder shell
It is welded with hopper, the hopper is connected to extruder shell, and the inner cavity of the extruder shell is equipped with shaft, the shaft
Outer wall is welded with screw thread, and the outer wall right part of the shaft is connected with angular wheel, before the output shaft of the angular wheel and motor
Active tooth engagement, the inner cavity right part of the shaft is held to be connected with internal heater by bearing, the right wall of the screw thread is welded with
Agitating device.
Preferably, external heating device described in three groups is electromagnetic heater, and the temperature of left part electromagnetic heater is less than
The temperature of its two groups of electromagnetic heater of right part.
Preferably, the internal heater is ceramic heating.
Preferably, the outer wall of the external heating device is enclosed with foam heat-insulation layer.
Preferably, the angular wheel is 40Cr alloy angular wheels.
Compared with prior art, the utility model has the beneficial effects that：This practicality uses internal heater and agitating device,
It is heated simultaneously inside and outside realizing so that former material internal/external heating is uniform, and using angular wheel, stable drive, noise is small and bearing capacity
Greatly, working environment is improved, the present apparatus may make internal former material to be heated evenly so that be uniformly mixed when former material melts, reduce finished product
Defect rate.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model shaft elevational cross-sectional view；
Fig. 3 is the utility model shaft left view.
In figure：1 extruder shell, 2 external heating devices, 3 hoppers, 4 shafts, 5 angular wheels, 6 motors, 7 screw threads, in 8
Set heater, 9 agitating devices.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of single screw extrusion machine, including outside extruder
The outer wall of shell 1, the extruder shell 1 is installed with three groups of external heating devices 2, and the top of the extruder shell 1 is left
Portion is welded with hopper 3, and the hopper 3 is connected to extruder shell 1, and the inner cavity of the extruder shell 1 is equipped with shaft 4, institute
The outer wall for stating shaft 4 is welded with screw thread 7, and the outer wall right part of the shaft 4 is connected with angular wheel 5, the angular wheel 5 and electricity
The inner cavity right part of the output shaft front end active tooth engagement of machine 6, the shaft 4 is connected with internal heater 8, the spiral shell by bearing
The right wall of tooth 7 is welded with agitating device 9.
Wherein, three groups of external heating devices 2 are electromagnetic heater, and the temperature of left part electromagnetic heater is less than its right part
The temperature of two groups of electromagnetic heaters, last one of the screw thread of material mouth 7 start to cry transportation section, and requirement cannot be plasticized former material here, but
It preheats, be pressurized compacted, internal heater 8 is ceramic heating, and the thermal efficiency is high, and heating is rapid, efficient, external heating device
2 outer wall is enclosed with foam heat-insulation layer, prevents heat excessive, results in waste of resources, and angular wheel 5 is 40Cr alloy conical tooths
Wheel, excellent in abrasion resistance improve service life.
Operation principle：Start external heating device 2, internal heater 8, is preheated, when temperature reaches requirement, former material
Enter the inner cavity of extruder shell 1 by hopper 3, start motor 6 so that the angular wheel 5 of shaft 4 rotates so that 4 turns of shaft
It is dynamic so that former material is moved by screw thread 7 towards the outlet of the present apparatus, former material by the external heating device of left part 2 be heated precompressed, squeeze
It is real, then pass through two groups of external heating devices 2 of right part and internal heater 8 so that former material compresses fusion plastification, passes through screw thread 7
On agitating device 9 be mixed, then pass through head outlet squeeze out.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
