Abstract
The utility model discloses an extrusion die, including the extrusion die head, in the overhead shaping hole that is equipped with of extrusion die, include taper hole and a cylinder hole more than the two -stage in proper order according to material extruded direction shaping hole, according to material extruded direction, the taper hole reduces at the tapering gradually. This structure has reduced the extrusion force of each grade, let density of pellet big, structure more closely, the content of better reduction moisture.
Description
Technical field
This utility model relates to extrusion die, especially relates to manufacture the extrusion die of the granular material such as feedstuff, biologic grain.
Background technology
For the granular material such as feedstuff, biologic grain, extruded generally by extrusion die.The extrusion die of the above-mentioned granular material of traditional molding is generally cylindrical hole, this sample loading mode, and material is through cylindrical hole, material is not subject to bigger pressure, and therefore, the density of the granule squeezed out is little, easily dispersion, the content of moisture is big, the moisture in bad control granule.
Now, the extrusion die with taper hole is occurred in that.Such as be 201420041582.3 applyings date to be 2014.1.23 authorized announcement date be disclosed in the patent documentation of 2014.7.30 in Chinese Patent Application No. a kind of fish meal forming ring mold, this fish meal forming ring mold includes annular die body and the multiple circular forming hole being arranged on annular die body, forming hole is in the cone ports that the aperture of circular die body Nei Bi one end is 60 °～70 °, fish meal is squeezed into forming hole by cone ports, the feed structure produced is tightr, water-soluble slowly, can in water suspension time longer, be conducive to the edible of fish.Although this forming ring mold can allow the structure of feedstuff more tight, but owing to material is extruded only in one-level cone ports, accordingly, it would be desirable to extruding force big, cause energy consumption big, and the time that material is extruded be short, be unfavorable for removing in material more moisture.
At Chinese Patent Application No. be 201420473260.6 applyings date to be 2014.8.20 authorized announcement date be disclosed in the patent documentation of the 2014.12.17 Novel ring-like mould of a kind of feeding stuff cuber; including ring mould body; ring mould body two ends are provided with bulge loop, are covered with the cylindrical hole of cylinder on ring mould body；Also being installed with one in ring mould body in the internal ring mould with heart shaped distribution, described internal ring mould is provided with bellmouth, and described bellmouth and cylindrical hole communicate.Its advantage is: the degree of depth of cylindrical hole just can greatly reduce, when using a period of time cylindrical hole blocking, owing to the material powder degree of depth being accumulated in cylindrical hole is shallower, wire brush is therefore adopted can ring mould to be cleared up, without boring machine, it is greatly improved the work efficiency of cleaner；Additionally, when being extruded by Inner extrusion device, material powder first passes through bellmouth, enter back into cylindrical hole, bellmouth can play pressure buffer effect from large to small so that material powder is subject to comparatively uniform pressure when being extruded, and can be effectively improved the forming effect of feedstuff through test, cut off back edge not cracky by cutter, decrease disqualification rate.
Although this forming ring mold can allow the structure of feedstuff more tight, but owing to material is extruded only in one-level cone ports, accordingly, it would be desirable to extruding force big, cause energy consumption big, and the time that material is extruded be short, be unfavorable for removing in material more moisture.
Summary of the invention
In order to reduce the extruding force of every one-level, allowing grain density is more big, structure is more tight, better reduce the content of moisture, this utility model provides a kind of extrusion die.
For reaching above-mentioned purpose, a kind of extrusion die, including extrusion die, extrusion die is provided with forming hole；Including the taper hole of more than two-stage and a cylindrical hole successively according to the direction forming hole of material extruding, according to the direction of material extruding, taper hole is gradually reduced at tapering.
Above-mentioned extrusion die structure, owing to being provided with multistage taper hole, and the tapering of taper hole is gradually reduced, therefore, direction according to material extruding, material is by compacting gradually, the density making granule is big, structure is more tight, and, extruding force required for every one-level is little, reduce energy consumption, simultaneously, the extruding of every one-level can squeeze out moisture, relative to prior art, allow in granule containing moisture better, additionally, owing to being provided with multistage taper hole, the stroke that material is extruded is long, in sum, from forming hole, grain density out is bigger, structure is more tight, moisture is few, it is not easy dispersion, smooth surface, the quality of granule is good.
Further, according to the direction of material extruding, taper hole includes one-level taper hole and two grades of taper holes successively, and the tapering of one-level taper hole is more than the tapering of two grades of taper holes.
Further, extrusion die is ring mould.It is easy to the granule such as formed feed, biologic grain.
Further, according to the direction of material extruding, it is provided with big cylindrical hole in the front of cylindrical hole.This structure, can shorten the length of cylindrical hole, and the granule of molding is easier to from forming hole to extrude, reduce the friction of granule and cylindrical hole, reduces energy consumption, and is more prone to clean cylindrical hole.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of extrusion die.
Fig. 2 is the sectional view of A-A in Fig. 1.
Fig. 3 is the enlarged drawing of B in Fig. 2.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.
As shown in Figure 1 to Figure 3, extrusion die includes pressurization die head 1, in the present embodiment, extrusion die 1 is ring mould, has cavity in ring mould, is provided with multiple forming hole 2 on the sidewall of ring mould, forming hole can be distributed on the sidewall of ring mould, it is possible to arranges forming hole 2 as required in other ways.
Including the taper hole of more than two-stage, a cylindrical hole 23 and big cylindrical hole 24 successively according to the direction forming hole 2 of material extruding, taper hole includes one-level taper hole 21 and two grades of taper holes 22 successively, and the tapering of one-level taper hole 21 is more than the tapering of two grades of taper holes 22.21, two grades of taper holes 22 of one-level taper hole, cylindrical hole 23 and big cylindrical hole 24 are coaxial, and the diameter of big cylindrical hole 24 is more than the diameter of cylindrical hole 23.In the present embodiment, the direction of material extruding refers to direction from inside to outside.
Above-mentioned extrusion die structure, owing to being provided with multistage taper hole, and the tapering of taper hole is gradually reduced, therefore, direction according to material extruding, material is by compacting gradually, the density making granule is big, structure is more tight, and, extruding force required for every one-level is little, reduce energy consumption, simultaneously, the extruding of every one-level can squeeze out moisture, relative to prior art, allow in granule containing moisture better, additionally, owing to being provided with multistage taper hole, the stroke that material is extruded is long, in sum, from forming hole, grain density out is bigger, structure is more tight, moisture is few, it is not easy dispersion, smooth surface, the quality of granule is good.
Owing to being provided with big cylindrical hole 24, so, can shortening the length of cylindrical hole 23, the granule of molding is easier to from forming hole 2 to extrude, reduce the friction of granule and cylindrical hole 23, reduces energy consumption, and is more prone to clean cylindrical hole 23.
