Description

Technical Field

[0001] This utility model relates to the field of ring die pellet mills, and more particularly to a mold for small ring die pellet mills. Background Technology

[0002] A ring die pellet mill (also known as a ring die feed mill or ring die pellet forming machine) is a feed pelleting equipment mainly used to directly compress crushed materials such as corn, soybean meal, straw, grass, and rice husks into pellet feed. Ring die pellet mills are widely used in large, medium, and small-scale aquaculture, grain and feed processing plants, livestock farms, poultry farms, individual farmers, and small and medium-sized farms.

[0003] The pellet mill die is an important component of the ring die pellet mill. Its structure and performance have a crucial impact on the production efficiency and product quality of the pellet mill. Small ring die pellet mill dies usually adopt a circular design with die holes and die heads. The size and shape of the die holes can be adjusted as needed.

[0004] The following problems exist with the molds used in small ring die pellet mills:

[0005] 1. The pellet mill molds are all fixed by fixing blocks. On average, a machine needs to use several fixing blocks to fix the molds. Each fixing block needs to be fixed with 2 high-strength screws of ≥8.8. When it is necessary to change the pellet mill mold with different mold holes, multiple screws need to be disassembled and installed, which is slow.

[0006] 2. The pellet mill mold is a flat surface, and the synchronous feeding disc sits directly on the flat surface. This connection method will cause a gap between the synchronous feeding disc and the mold. When the feeding disc rotates, the material will leak out from the gap between the two and dust will be generated.

[0007] Therefore, there is a need to propose a mold for small ring die pellet mills to solve the problems mentioned in the background art. Utility Model Content

[0008] The purpose of this utility model is to provide a mold for a small ring die pellet mill. The device has a threaded hole and a positioning groove that cooperate with each other, which makes the installation and disassembly more efficient. At the same time, the sealing groove cooperates with the feeding plate to eliminate the gap between the ring die body and the feeding plate, reducing material leakage and dust.

[0009] The purpose of this utility model is to provide a mold for a small ring die pellet mill, including a ring die body. The annular surface of the ring die body is provided with multiple through ring die holes. One side surface of the ring die body is provided with a positioning groove that cooperates with the ring die pellet mill. The surface of the ring die body is provided with multiple threaded holes for fixing the ring die body. Two sealing grooves for sealing are provided on the upper and lower sides of the annular inner side of the ring die body.

[0010] Furthermore, multiple ring mold holes are arranged in a honeycomb array on the annular surface of the ring mold body.

[0011] Furthermore, one end of each of the multiple ring die holes on the inner side of the ring die body is tapered.

[0012] Furthermore, multiple threaded holes are provided on the other side surface of the ring die body for fixing to the ring die pellet mill.

[0013] Furthermore, an annular connecting groove is provided on the other side surface of the ring die body for sealing connection with the ring die pellet mill.

[0014] The working principle and usage principle of this utility model are as follows: During installation, the positioning groove engages with the positioning pin of the ring die pellet mill body, aligning multiple threaded holes with the holes in the ring die pellet mill body. Then, screws with a strength ≥8.8 are used for fixing. During disassembly, simply loosen the screws fastened to the ring die pellet mill body. The sealing groove connects with the feeding disc inside the ring die pellet mill. During operation, the feeding disc interlocks with the sealing groove inside the ring die body, eliminating the gap between them. Only after the ring die pellet mill and the positioning groove are engaged, the screws need to be tightened. Compared to the old-style mold, this reduces the equipment manufacturing cost. The interlocking of the threaded holes and positioning groove results in higher efficiency during installation and disassembly. Simultaneously, the sealing groove and feeding disc eliminate the gap between the ring die body and the feeding disc, reducing material leakage and dust generation.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: During installation, the positioning groove engages with the positioning pin of the ring die pellet mill body, aligning multiple threaded holes with the holes in the ring die pellet mill body. Then, screws with a strength ≥8.8 are used for fixing. During disassembly, simply loosen the screws fastened to the ring die pellet mill body. The sealing groove connects with the feeding disc inside the ring die pellet mill. During operation, the feeding disc interlocks with the sealing groove inside the ring die body, eliminating the gap between them. Only after the ring die pellet mill and the positioning groove are engaged, the screws need to be tightened. Compared with the old-style mold, this reduces the equipment manufacturing cost. The interlocking of the threaded holes and positioning groove results in higher efficiency during installation and disassembly. Simultaneously, the engagement of the sealing groove and the feeding disc eliminates the gap between the ring die body and the feeding disc, reducing material leakage and dust generation.

[0016] 1. Compared with the existing technology, this utility model has the advantage that it only requires the ring die pellet mill and the positioning groove to be matched and the screws to be tightened. Compared with the old mold, it reduces the manufacturing cost of the equipment. The threaded hole and the positioning groove cooperate with each other, which makes the installation and disassembly more efficient.

[0017] 2. Compared with the prior art, the present invention has the advantages of sealing groove and material feeding plate cooperating to eliminate the gap between the ring die body and material feeding plate, thereby reducing material leakage and dust. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0024] A mold for a small ring die pellet mill, as described in this specific embodiment, is as follows: Figure 1-4 As shown, a mold for a small ring die pellet mill includes a ring die body 1, which is installed inside the small ring die pellet mill. Multiple through-holes 2 are formed on the annular surface of the ring die body 1, which granulate the material inside the ring die body 1. A positioning groove 3, which mates with the ring die pellet mill, is formed on one side of the ring die body 1. Multiple threaded holes 4 are formed on the surface of the ring die body 1 for fixing the ring die body 1. The positioning groove 3 aligns with the positioning pins of the ring die pellet mill body, and is then fixed with screws. Two sealing grooves 5 are formed on the upper and lower sides of the annular inner side of the ring die body 1, and the sealing grooves 5 are connected to the feeding disc inside the ring die pellet mill.

[0025] With the above technical solution, during installation, the positioning groove 3 engages with the positioning pin of the ring die pellet mill body, aligning multiple threaded holes 4 with the holes in the ring die pellet mill body. Then, screws with a strength ≥8.8 are used for fixing. During disassembly, simply loosen the screws fastened to the ring die pellet mill body. The sealing groove 5 connects to the feeding disc inside the ring die pellet mill. During operation, the feeding disc interlocks with the sealing groove 5 inside the ring die body 1, eliminating the gap between them. Only after the ring die pellet mill and the positioning groove 3 are engaged, the screws need to be tightened. Compared to the old-style mold, this reduces the equipment manufacturing cost. The interlocking of the threaded holes 4 and the positioning groove 3 improves efficiency during installation and disassembly. Simultaneously, the sealing groove 5, in conjunction with the feeding disc, eliminates the gap between the ring die body 1 and the feeding disc, reducing material leakage and dust generation.

[0026] like Figure 1-4 As shown, multiple ring mold holes 2 are arranged in a honeycomb pattern on the annular surface of the ring mold body 1.

[0027] The above technical solution facilitates the uniform discharge of particles when the material in the ring die body 1 passes through multiple ring die holes 2 for granulation.

[0028] like Figure 1-4 As shown, one end of each of the multiple ring die holes 2 on the inner side of the ring die body 1 is tapered.

[0029] The above technical solution facilitates the smoother delivery of particles into multiple ring die holes 2 during the granulation process.

[0030] like Figure 1-4 As shown, multiple threaded holes 6 are provided on the other side surface of the ring die body 1 for fixing to the ring die pellet mill.

[0031] The above technical solution allows for the fixed connection between the ring die pellet mill and multiple threaded holes 6, facilitating the stabilization of the ring die body 1.

[0032] like Figure 1-4 As shown, an annular connecting groove 7 for sealing connection with the ring die pellet mill is provided on the other side surface of the ring die body 1.

[0033] By using the above technical solution, the ring die pellet mill and the annular connecting groove 7 are slidably engaged, which can prevent the material inside the ring die body 1 from floating out and reduce material leakage and dust.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
