Referring to fig. 1, the utility model relates to a feed granulating ring mould, which comprises a ring mould body 1, and is characterized in that: a pressing mechanism is arranged in the ring die body 1, the pressing mechanism is provided with a frame body 2, compression rollers 3 are symmetrically arranged at two ends of the frame body 2, and each compression roller 3 is correspondingly provided with a refining mechanism close to the compression roller 3; the material homogenizing mechanism is provided with a fixed rod 4, one end of the fixed rod 4 is in bolted connection with the frame body 2, the other end of the fixed rod 4 is fixedly provided with a material homogenizing plate 5, one end, close to the compression roller 3, of the material homogenizing plate 5 is matched with the inner wall of the ring die body 1, and an included angle is formed between one end, far away from the compression roller 3, of the material homogenizing plate 5 and the inner wall of the ring die body 1; the ring die body 1 is provided with a plurality of sectional die holes 6 along the radial direction.

The main problems of the feed granulating ring mold are that the material enters between the ring mold and the press roll in the process of granulating the ring mold, the ring mold is driven by a motor (not shown in the figure) to rotate through a speed reducer, the press roll arranged in the ring mold only rotates and does not revolve under the action of the material between the mold rolls and the friction force between the material and the press roll, meanwhile, the material rotates under the action of the friction force, the material is unevenly distributed and enters between the press roll and the ring mold to be pressed, the material is continuously extruded from a straight hole/a conical hole or a mold hole formed by combining the conical hole and the straight hole, so that the distribution is uneven in the granulating process, and the problem that the compactness of the extruded columnar feed is uneven, the granules are loose and high in pulverization rate and the quality of the granules is influenced due to the unreasonable design of the shape of the mold hole. And this application is close to through refining mechanism and corresponding compression roller 3, and refining plate 5 keeps away from the one end of compression roller 3 and the inner wall of ring mould body 1 and has the contained angle, makes in the material gets into the contained angle space earlier, again by the even tiling of part with the inner wall looks adaptation of ring mould body 1 of refining plate 5, the flattening back is forced immediately by the compression roller 3 that is close to it and is impressed the ring mould hole and discharge in the sectional type nib. Because the material homogenizing plate 5 is close to the press roller 3, the press roller is prevented from being driven to rotate by the ring die when the motor drives the ring die to rotate, and the material is prevented from being paved in time and better when rotating under the action of friction force. And the material homogenizing mechanism is matched with the sectional type die holes 6, so that the prepared particles are hard, good in strength and good in particle quality.

In one embodiment, referring to fig. 2, the sectional die hole 6 comprises a feeding inner cone hole 601, a curved hole 602, a straight effective hole 603 and a straight pressure reducing hole 604 which are communicated in sequence from inside to outside.

The cone opening of the feeding inner cone hole 601 can be 30-60 degrees, the aperture of the feeding inner cone hole gradually decreases from the feeding end to the discharging end, and the design can reduce the inlet hole resistance of the material and is beneficial to the smooth entry of the material into a die hole. The outlet of the feeding inner cone hole 601 is smoothly transited to the inlet of the curved hole 602, and the curved hole 602 can prolong the extrusion time of materials in the die hole, so that hard feed granules can be conveniently prepared. The outlet of the curved hole 602 is in smooth transition with the inlet of the straight effective hole 603, and the straight effective hole 603 is a granulating hole, so that the columnar feed with the same diameter can be produced conveniently. The straight pressure relief vent 604 ensures that the feed can quickly come out of the straight effective vent 603. And the die holes of 6 groups of two adjacent rows of sectional die holes on the ring die 1 are arranged in a staggered manner, so that the aperture ratio of the ring die holes is increased, and the yield of feed granulation is improved. Due to the designed sectional die hole 6, the stroke of extruding the material is long, the pellet feed coming out from the straight pressure reducing hole 604 has higher density, less moisture content, difficult dispersion, smooth surface and good pellet quality.

In one embodiment, referring to fig. 2, the inner diameter of the curved hole 602 is gradually decreased. By the design, according to the extrusion direction of the material, the inner diameter of the curved hole 602 is gradually reduced, so that the material can be gradually compacted, and the density of material particles is increased, so that the material particles are harder.

In one embodiment, referring to fig. 2, the inner diameter of the outlet of the curved hole 602 is the same as the inner diameter of the straight effective hole 603. By the design, stable transition of materials to the straight effective holes 603 is facilitated, and feed with uniform compactness can be conveniently prepared.

In one embodiment, referring to FIG. 2, the inner diameter of the straight relief vent 604 is greater than the inner diameter of the straight relief vent 603. By the design, the granular feed can be extruded out of the straight pressure reducing hole 604 more easily, and energy consumption is reduced.

In an embodiment, referring to fig. 3, a cross-hatch 301 is formed on a surface of the press roller 3. The press roll 3 thus designed greatly enhances the performance of preventing the press roll 3 from slipping.

In an embodiment, referring to fig. 1, a roll surface of the press roll 3 is in clearance fit with an inner wall of the ring die body 1. The design is convenient for forcedly pressing the material into the ring die holes and discharging the material from the sectional die holes.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the present invention.
