Description
Technical field
It the utility model is related to a kind of comminutor, and in particular to a kind of screw extrusion type comminutor.
Background technology
Benzoic acid, sodium benzoate are in order that used time quickening is dissolved, it is necessary to prepare granular material.Benzoic acid, benzoic acid
Sodium crystallizes first is cut into flat crystal by slicer, then squeezes out granular material using squash type comminutor.Squash type
Comminutor is in conveying, extrusion process, and when feed worm retreats, conveying screw thread is easy to strip backward, so as to cause returning charge.
The content of the invention
In order to solve the above problems, there is provided a kind of screw extrusion type comminutor for preventing returning charge in conveying, extrusion process.
The technical solution adopted in the utility model is：Screw extrusion type comminutor, including the cylinder 1 laterally set, cylinder 1
Top is provided with the funnelform storehouse 2 that feeds intake, and one end of the cylinder 1 is provided with extrusion die 3, and the inside of cylinder 1 is provided with feed worm 4,
The one end of feed worm 4 is provided with rotating driving device 5, and rotating driving device 5 is outside cylinder 1, it is characterised in that feed worm 4
On the Unequal distance of conveying screw thread 6, by the side of 5 lateral extrusion mould of rotating driving device 3, conveying screw thread 6 is by dilute to close.
Optimization of the present utility model, it is from coarse to fine by the side of 5 lateral extrusion mould of rotating driving device 3, cylinder 1.
Further optimization, the inwall of cylinder 1 are provided with anti-returning charge screw thread 7, and the anti-cross section of returning charge screw thread 7 is oblique triangle, tiltedly
Triangle tilts towards the direction of extrusion die 3.
Further optimization, extrusion die 3 includes the extrusion correspondence of preceding mould 31 and rear mold 32, preceding mould 31 and rear mold 32, preceding
Mould 31 is fixed with cylinder 1, and the relatively preceding mould 31 of rear mold 32 is rotatable.
Operation principle of the present utility model is：For feed worm 4 during material is conveyed, material enters the front end of screw rod,
Because pressed end conveying screw thread is closeer than rear end, pressed end conveying material pressure is big, natural to extrude material from extrusion die 3.
The utility model has the advantage that and positive had the technical effect that：The utility model passes through Unequal distance conveying screw thread solution
Determine conveying, extrusion process returning charge problem, it is simple in construction, suitable for large-scale promotion.
Brief description of the drawings
Fig. 1 is the structural representation of screw extrusion type comminutor；
Fig. 2 is the optimization structural representation of screw extrusion type comminutor；
Fig. 3 is the structural representation of extrusion die；
Reference：Cylinder -1, the storehouse -2 that feeds intake, extrusion die -3, preceding mould -31, rear mold -32, feed worm -4, rotation are driven
Dynamic device -5, conveying screw thread -6, anti-returning charge screw thread -7.
Embodiment
In order that technological means of the present utility model, creation characteristic, reached purpose and effect are easy to understand, in conjunction with
Specific embodiments and the drawings, the utility model is further elaborated.
Refer to shown in Figure of description 1 and Fig. 3, the utility model provides screw extrusion type comminutor, including transverse direction
The cylinder 1 of setting, the top of cylinder 1 are provided with the funnelform storehouse 2 that feeds intake, and one end of the cylinder 1 is provided with extrusion die 3, in cylinder 1
Portion is provided with feed worm 4, and the one end of feed worm 4 is provided with rotating driving device 5, and for rotating driving device 5 outside cylinder 1, it is special
Sign is, the Unequal distance of conveying screw thread 6 on feed worm 4, by the side of 5 lateral extrusion mould of rotating driving device 3, conveying screw thread 6
By dilute to close.
This specific embodiment feed worm 4 is during material is conveyed, and material enters the front end of screw rod, because pressed end is defeated
Expect that screw thread is closeer than rear end, pressed end conveying material pressure is big, natural to extrude material from extrusion die 3.
The utility model has the advantage that and positive had the technical effect that：The utility model passes through Unequal distance conveying screw thread solution
Determine conveying, extrusion process returning charge problem, it is simple in construction, suitable for large-scale promotion.
In order to further be easy to extrude, returning charge in course of conveying is avoided.The optimization of above-mentioned embodiment, such as specification
It is from coarse to fine by the side of 5 lateral extrusion mould of rotating driving device 3, cylinder 1 shown in accompanying drawing 2.
In order to further avoid returning charge in course of conveying.Further optimization, the inwall of cylinder 1 are provided with anti-returning charge screw thread 7,
The anti-cross section of returning charge screw thread 7 is oblique triangle, and oblique triangle tilts towards the direction of extrusion die 3.
Feed worm rotary squeezing extrusion die 3 in rotary course, feed worm will be to squeezing in spin extrusion process
Go out mould 3 and produce torsion breakage.Further optimization, extrusion die 3 include preceding mould 31 and rear mold 32, preceding mould 31 and rear mold 32 it is crowded
Outlet is corresponding, and preceding mould 31 is fixed with cylinder 1, and the relatively preceding mould 31 of rear mold 32 is rotatable.Feed worm in spin extrusion process, after
Mould 32 rotates together with feed worm, and because the extrusion of rear mold 32 and preceding mould 31 is corresponding, therefore rear mold 32 rotates and do not influenceed
Pressing materials.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
