Description
Technical Field
The utility model relates to a granulator circular mold, especially a large-scale circular mold of material granulator of novel nib.
Background
The ring die is an important part of the material granulator. The material is pressed by the press rolls through the holes of the ring die and then broken into material particles.
Conventional material pelletizers typically increase the density of the material pellets by increasing the depth of the shaping holes to reduce the expansion spring back of the material pellets. However, increasing the depth of the forming hole requires increasing the thickness of the ring die, which causes an increase in the material cost of the ring die and makes it difficult to effectively increase the density of the material particles.
SUMMERY OF THE UTILITY MODEL
For solving the not enough of prior art, the utility model provides a novel material granulator ring mould in nib can effectively promote the density of material granule.

the inner ring die is provided with a primary feeding hole and a primary forming hole; the die orifice piece is provided with a transition hole, a secondary feeding hole, a secondary forming hole and a pressure reducing hole; the primary feeding hole, the primary forming hole, the transition hole, the secondary feeding hole, the secondary forming hole and the pressure reducing hole are communicated in sequence and are coaxially arranged; the primary feeding hole and the secondary feeding hole are both conical holes; the primary forming hole, the transition hole and the secondary forming hole are all cylindrical holes; the diameter of the transition hole is larger than the diameters of the primary forming hole and the secondary forming hole.
Further, the depth of the secondary molding hole is greater than the depth of the primary molding hole.
Further, the diameter of the large end of the primary feeding hole is larger than that of the transition hole; the diameter of the small end of the primary feed hole is equal to the diameter of the primary forming hole.
Further, the diameter of the large end of the secondary feeding hole is equal to that of the transition hole; the diameter of the small end of the secondary feeding hole is equal to the diameter of the secondary forming hole.

The utility model discloses an useful part lies in, can effectively promote the density of material granule.
After the pressure of the transition hole is released, the secondary extrusion molding is carried out through the secondary feeding hole and the secondary molding hole, so that the density of material particles can be effectively improved. Compared with the traditional mode of increasing the depth of the forming hole and increasing the density, the increase of the material cost caused by the over-thick wall thickness of the ring die is avoided, and because the secondary extrusion forming is carried out again after pressure release, the rebound expansion rate of the formed material particles is lower, and the density of the material particles is effectively improved.
The abrasion degree of the inner ring die is far greater than that of the outer ring die due to the action force directly transmitted by the compression roller in the working process.

After the outer ring die is worn, the outer ring die can be maintained by replacing the die hole piece, the whole outer ring die does not need to be replaced, and the maintenance cost is low.
The relief vent does not bear the primary extrusion force as compared to the post-forming vent, and the thickness of the outer ring mold can be reduced by projecting the portion of the relief vent to the outside of the outer ring mold.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, a novel material granulator circular mold 100 with mold holes comprises: an inner ring die 10, an outer ring die 20, a die orifice 30, and a nut 40. The outer ring mold 20 is fitted around the outer circumference of the inner ring mold 10. The outer ring mold 20 is formed with a mounting hole. Specifically, the mounting hole is a stepped hole. The orifice member 30 is a T-shaped column. The orifice member 30 is fitted into the mounting hole. One end of the orifice member 30 is provided with an external thread structure. The nut 40 forms a threaded connection with the external thread structure to fix the die orifice 30 to the outer ring die 20.
As a preferred embodiment, the inner ring die 10 is formed with primary feed holes 11 and primary molding holes 12. The orifice member 30 is formed with a transition orifice 31, a secondary feed orifice 32, a secondary shaping orifice 33, and a relief orifice 34. The primary feeding hole 11, the primary forming hole 12, the transition hole 31, the secondary feeding hole 32, the secondary forming hole 33 and the pressure reducing hole 34 are communicated in sequence and coaxially arranged.
The primary feed hole 11 and the secondary feed hole 32 are both tapered holes. The primary molding hole 12, the transition hole 31 and the secondary molding hole 33 are all cylindrical holes. The diameter of the transition hole 31 is larger than the diameters of the primary molding hole 12 and the secondary molding hole 33.
After the pressure of the transition hole 31 is released, the secondary extrusion molding is carried out through the secondary feeding hole 32 and the secondary molding hole 33, so that the density of material particles can be effectively improved. The conventional way to increase the density is usually to increase the depth of the molding holes. Compared with the traditional density increasing mode, the secondary extrusion forming mode avoids the increase of material cost caused by the over-thick wall thickness of the ring die, and because the secondary extrusion forming mode is subjected to secondary extrusion forming after pressure relief, the rebound expansion rate of the formed material particles is lower, and the density of the material particles is effectively improved.
As a preferred embodiment, the depth of the secondary molding hole 33 is greater than the depth of the primary molding hole 12. The wall thickness of the inner ring die 10 may be set to be thin, and the inner ring die 10 is worn to a much greater extent than the outer ring die 20 by the force directly transmitted from the press rolls during operation. And after the inner ring die 10 is worn, the cost for replacing the inner ring die 10 is low. After the outer ring die 20 is worn, the die hole can be maintained by replacing the die hole piece 30, the whole outer ring die 20 does not need to be replaced, and the maintenance cost is low.
As a specific embodiment, the diameter of the large end of the primary feed hole 11 is larger than the diameter of the transition hole 31. The diameter of the small end of the primary feed hole 11 is equal to the diameter of the primary molding hole 12. The diameter of the large end of the secondary feed hole 32 is equal to the diameter of the transition hole 31. The diameter of the small end of the secondary feed hole 32 is equal to the diameter of the secondary molding hole 33. The depth of the secondary feed holes 32 is greater than the depth of the primary feed holes 11. Can effectively keep the particle size of the finished product of the material and has high stability.
In a specific embodiment, the ratio of the depth of the transition hole 31 to the diameter of the transition hole 31 is 0.3 or more and 0.5 or less.
As a specific embodiment, the pressure relief vent 34 is a cylindrical vent. The diameter of the pressure-reducing hole 34 is larger than that of the secondary molding hole 33. The relief vent 34 is partially located outside of the outer ring mold 20. The relief holes 34 do not bear the primary pressing force as compared to the secondary molding holes 33, and the portion of the relief holes 34 protruding outside the outer ring mold 20 can reduce the thickness of the outer ring mold 20.
As a specific embodiment, the secondary molding hole 33 has a smaller diameter than the primary molding hole 12.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
