Abstract
The utility model provides a kind of herringbone grooved ring die of granulator; comprise ring mould body (1); ring mould internal circular surfaces is provided with some grooves; groove is divided into elongated slot and short groove along the axial direction of ring mould; two groups of grooves extend from the both ends of the surface of ring mould with the middle part of the contrary helix of rotation direction to ring mould respectively; each short groove extends between the corresponding two adjacent elongated slots in elongated slot, is processed with equidistant radial nib along groove direction on ring mould.Angle after described elongated slot and short groove and ring mould flatten is 45 °, and the distance between elongated slot is equal, and the distance between short groove is equal.Elongated slot extends beyond the center line of ring mould axial direction, and short groove extends not more than the center line of ring mould axial direction.Chevron shaped grooved ring mould is with pressure roller extrusion process, and material can produce micro-slip to both sides in groove, makes the material in non-compacted region move in nib, ring mould even wearing, and coiled strip is strong, improves the service life of ring mould, is easy to promote, good in economic efficiency.
Description
Technical field
The utility model relates to a kind of granulator key equipment, especially relates to a kind of herringbone grooved ring die of granulator, belongs to feed processing technology field.
Background technology
It is a kind of novel hay varieties in current feed industry that the stalk fibre mixed feed process of rubbing powdering is crushed to pellet, wherein ring mould granulator is most popular type, feed granules is in process, forage mixture enters ring mould nib by the extruding of ring mould and pressure roller, current ring die of granulator inner surface is processed into the smooth face of cylinder, the feed between blanketed zone is made to be subject to one dimension restraining force, the shearing strength of feed is lower, to exist and ring mould moves rightabout shear displacemant, the linear velocity of pressure roller is significantly less than the linear velocity of ring mould, the invalid wearing and tearing of pressure roller and ring mould are increased, thus reduce production efficiency, reduce the service life of ring mould.
Utility model content
In order to the invalid wearing and tearing overcoming the existence of existing ring mould are large, the deficiency that service life is shorter, the utility model provides a kind of herringbone grooved ring die of granulator.
The utility model for the taked technical scheme that achieves the above object is:
A kind of herringbone grooved ring die of granulator; comprise ring mould body (1); ring mould internal circular surfaces is provided with some grooves; described groove is divided into elongated slot and short groove along the axial direction of ring mould; two groups of grooves extend from the both ends of the surface of ring mould with the middle part of the contrary helix of rotation direction to ring mould respectively; each short groove extends between the corresponding two adjacent elongated slots in elongated slot, is processed with equidistant radial nib along groove direction on ring mould.
Angle after described elongated slot and short groove and ring mould flatten is 45 °.
Distance between described elongated slot is equal, and the distance between described short groove is equal.
Described elongated slot extends beyond the center line of ring mould axial direction, and described short groove extends not more than the center line of ring mould axial direction.
The beneficial effects of the utility model are:
A kind of herringbone grooved ring die of granulator of the present utility model; on ring mould internal circular surfaces, axial direction is provided with chevron shaped groove; chevron shaped grooved ring mould is with pressure roller extrusion process; material can produce micro-slip to both sides in groove, makes the material in non-compacted region move in nib, ring mould even wearing; coiled strip is strong; improve the service life of ring mould, be easy to promote, good in economic efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1: ring mould body.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
If Fig. 1 is structural representation of the present utility model; a kind of herringbone grooved ring die of granulator; comprise ring mould body (1); ring mould internal circular surfaces is provided with some grooves; described groove is divided into elongated slot and short groove along the axial direction of ring mould; two groups of grooves extend from the both ends of the surface of ring mould with the middle part of the contrary helix of rotation direction to ring mould respectively, and each short groove extends between the corresponding two adjacent elongated slots in elongated slot, is processed with equidistant radial nib along groove direction on ring mould.
Angle after described elongated slot and short groove and ring mould flatten is 45 °, chevron shaped grooved ring mould is with pressure roller extrusion process, material can produce micro-slip to both sides in groove, the material in non-compacted region is made to move in nib, ring mould even wearing, coiled strip is strong, improves the service life of ring mould, be easy to promote, good in economic efficiency.Distance between described elongated slot is equal, and the distance between described short groove is equal.Described elongated slot extends beyond the center line of ring mould axial direction, and described short groove extends not more than the center line of ring mould axial direction.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of embodiment of the present utility model shown in accompanying drawing, actual apparatus structure is not limited thereto.So those of ordinary skill in the art can also do other changes in the utility model spirit, these changes made according to the utility model spirit, all should be included in the scope required by the utility model certainly.
