Description

Technical Field

[0001] This utility model relates to the field of feed processing equipment technology, and in particular to a novel feed extrusion die. Background Technology

[0002] Feed extrusion molding is a crucial step in feed production, and its die design directly affects the shape, density, and production efficiency of feed pellets. Traditional extrusion dies are mostly one-piece structures, with the extrusion orifice directly formed on the die body, which presents the following problems:

[0003] (1) Non-removable maintenance: When the local extrusion hole is blocked or worn, the entire mold needs to be replaced, which is costly and wasteful;

[0004] (2) Poor adaptability: The entire mold needs to be replaced for different sizes of feed, resulting in insufficient flexibility;

[0005] (3) Low extrusion uniformity: The hole distribution of traditional molds is uniform, which easily leads to uneven material output. Utility Model Content

[0006] (1) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a novel feed extrusion die, including a die body, mounting holes, and a die assembly. The die body is installed at the discharge end of an extruder. The die body has a plurality of mounting holes evenly distributed on it. The die assembly is detachably installed in the mounting holes. The die assembly is a boss structure integrally formed by a first truncated cone and a second truncated cone. The diameter of the first truncated cone is larger than the diameter of the second truncated cone. The die assembly has a plurality of extrusion holes.

[0008] Preferably, the mold body has several fixing holes at its center, and the mold body is installed at the discharge end of the extruder by bolts fitting into the fixing holes.

[0009] Preferably, the shape and size of the mounting hole are adapted to the mold assembly.

[0010] Preferably, the mold body is disc-shaped, and a plurality of mounting holes form a multi-layered annular array along the center to the edge of the mold body, with the mounting holes between adjacent layers being staggered.

[0011] Preferably, the mold assembly is made of high-temperature and high-pressure resistant plastic material.

[0012] (2) Beneficial effects

[0013] This utility model provides a novel feed extrusion die, which has the following advantages compared with the prior art:

[0014] 1. Mold components can be independently disassembled and replaced, reducing maintenance costs;

[0015] 2. The multi-layered, staggered mounting holes and porous structure within the components ensure uniform distribution of discharge pressure and improve feed forming quality;

[0016] 3. By changing mold components of different specifications, the shape and size of feed pellets can be quickly adjusted, making it highly adaptable. Attached Figure Description

[0022] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown, the present invention discloses a novel feed extrusion die, comprising a die body 1, mounting holes 2, and a die assembly 3. The die body is installed at the discharge end of an extruder. The die body 1 has a plurality of mounting holes 2 evenly distributed thereon. The die assembly 3 is detachably installed within each mounting hole 2. The die assembly 3 is a boss structure integrally formed from a first frustum 31 and a second frustum 32. The diameter of the first frustum 31 is larger than the diameter of the second frustum 32, and a limiting step is formed at their connection to ensure stable installation. The die assembly 3 has a plurality of extrusion holes 33 for feed extrusion molding.

[0024] The mold body 1 has several fixing holes 11 at its center. The mold body 1 is installed at the discharge end of the extruder by the fit between the bolts and the fixing holes 11.

[0025] The shape and size of the mounting hole 2 are adapted to the mold assembly 3, and the width of the mounting hole 2 is set from wide to narrow along the feed extrusion direction.

[0026] The mold body 1 is disc-shaped, and a number of mounting holes 2 form a multi-layered annular array along the center to the edge of the mold body 1. The mounting holes 2 between adjacent layers are staggered to ensure uniform distribution of discharge pressure and improve feed forming quality.

[0027] The mold assembly 3 is made of high-temperature and high-pressure resistant engineering plastics (such as reinforced nylon or polyether ether ketone PEEK).

[0028] Working principle:

[0029] Mold installation: Fix the mold body 1 to the extrusion end of the extruder with bolts, ensuring that the fixing hole 11 is aligned with the extruder flange;

[0030] Component assembly: Press the mold component 3 into the mounting hole 2. The material enters the mold component 3 through the inner cavity of the mold body 1 and is formed into strip-shaped feed through the extrusion hole 33.

[0031] Replacement procedure: Use tools to push the blocked or worn mold assembly 3 out of the mounting hole 2;

[0032] Install new components: Press the new mold component axially along the mounting hole.

[0033] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
