Description

Technical Field

[0001] The utility model relates to the technical field of livestock and poultry feed pellet granulators, in particular to a flat die of a poultry pellet feed granulator. Background Technique

[0002] The main components of a flat die feed pellet machine are a flat round steel die and a set of grooved rollers that can rotate freely. The raw materials fall from top to bottom into the gap between the rollers and are pressed into the die holes by the rotating rollers. Long cylindrical objects are extruded from below the die holes and cut into pellets by knives. Essentially, it uses grooved rollers to extrude and granulate the materials. Among them, the die holes of the flat die bear great frictional force and extrusion force. After working for a period of time, the temperature of the flat die rises and the heat cannot be dissipated in time, resulting in deformation of the flat die or even deformation of some die holes. Once the above situation occurs, the entire flat die can only be replaced, causing problems such as low utilization rate of the flat die and increased production costs.

[0003] In the existing Chinese patent CN205962766U, a flat die for a feed pellet machine is disclosed. By setting bolt holes, grooves, tapered forming holes, strengthening blocks, etc., the materials can effectively enter the forming holes, achieving effects such as improving the material utilization rate. However, it still cannot solve the problems faced in the prior art, such as insufficient heat dissipation capacity of the flat die, easy deformation, inconvenient maintenance, and low utilization rate.

[0004] Now, a flat die for a poultry feed pellet granulator is provided. With an assembled design, it greatly enhances the heat dissipation efficiency of the flat die. At the same time, it is also convenient to perform local maintenance on the flat die, which can greatly increase the utilization rate of the flat die and is beneficial to cost savings. Content of the Utility Model

[0005] In view of the above situation, in order to overcome the deficiencies of the prior art, the utility model provides a flat die of a poultry pellet feed granulator, effectively solving the problems of insufficient heat dissipation capacity of the flat die, easy deformation, inconvenient maintenance, and low utilization rate faced in the prior art.

[0006] The technical solution it adopts is as follows: It includes two horizontal and coaxial circular plates with a gap between them. There are multiple cylindrical blocks in the gap. The two circular plates can clamp the two ends of the cylindrical blocks to make them fixed. Vertical first through holes are provided on the cylindrical blocks, and the end openings of the through holes are in the shape of a conical surface. Multiple conical protrusions corresponding to the cylindrical blocks one by one are provided on the circular plates, and the outer edge surface of the conical protrusions is in close contact with the conical surface at the end of the through hole; second through holes are provided at the conical protrusions, and the second through holes correspond to the first through holes one by one and are coaxial.

[0007] Furthermore, a vertical bolt is fixed on the upper circular plate. The bolt passes through the lower circular plate, and a nut is screwed at the lower end of the bolt. Screwing the nut can make the two circular plates approach each other and clamp the multiple cylindrical blocks.

[0008] Furthermore, the diameter of the first through hole is smaller than that of the second through hole.

[0009] The structure of the utility model is ingenious. With an assembled design, the heat dissipation efficiency of the flat die is greatly enhanced. At the same time, it is convenient to perform local maintenance on the flat die, which can greatly increase the utilization rate of the flat die and is beneficial to cost saving.

[0016] The following further elaborates on the specific embodiments of the utility model with reference to the accompanying drawings.

[0017] As given by Figures 1 to 6 , the utility model includes two horizontal and coaxial circular plates 1. There is a gap between the two circular plates 1. Inside the gap, there are multiple cylindrical blocks 2. The two circular plates 1 can clamp the two ends of the cylindrical blocks 2 to make them fixed. A vertical first through hole 3 is provided on the cylindrical block 2. The opening at the end of the through hole is a conical surface. Multiple conical protrusions 4 corresponding to the cylindrical blocks 2 are provided on the circular plate 1. The outer edge surface of the conical protrusion 4 is in close contact with the conical surface at the end of the through hole; A second through hole 5 is provided at the conical protrusion 4. The second through hole 5 corresponds to the first through hole 3 one by one and is coaxial.

[0018] In order to firmly fix the multiple cylindrical blocks 2 between the two circular plates 1, a vertical bolt 6 is fixed on the upper circular plate 1. The bolt 6 penetrates the lower circular plate 1. A nut 7 is screwed at the lower end of the bolt 6. Screwing the nut 7 can make the two circular plates 1 approach each other and clamp the multiple cylindrical blocks 2.

[0019] In order to facilitate feeding and discharging better, the diameter of the first through hole 3 is smaller than that of the second through hole 5.

[0020] It should be noted that the shape of the die holes of the existing flat die is as shown in Figure 1 and is similar to a stepped shape. Such a design is for the material to be more conveniently extruded into the die holes and for the material to be easily separated from the die holes, reducing the extrusion resistance. Thus, the thinnest part in the middle of the stepped holes is the main heat generation part and also the part with the fastest wear. In this solution, the die holes are divided into three sections, and the middle section that determines the particle diameter is the first through hole 3 in this application. When a large deformation or damage occurs in the first through hole 3, only the damaged cylindrical block 2 needs to be replaced.

[0021] Of course, there are gaps between adjacent cylindrical blocks 2. Thus, even if heat appears during the pelletizing extrusion process, the heat can be dissipated in time, preventing the cylindrical blocks 2 from expanding due to heat absorption and also facilitating the normal progress of the pelletizing work.

[0022] During use, this device is fixed on a flat die pelletizer, and then the grooved roller rotates to extrude the material. The material enters through the second through hole 5 in the upper circular plate 1, then becomes strip-shaped after passing through the first through hole 3 in the cylindrical block 2, and finally goes downward through the second through hole 5 on the lower side and is finally formed into pellets after being cut by the cutting tool.

[0023] After using for a period of time, the first through hole 3 in some of the cylindrical blocks 2 is severely worn. Only the nut 7 needs to be removed and the severely worn cylindrical block 2 replaced, which is convenient for maintenance and greatly improves the utilization rate.

[0024] The utility model has a clever structure and adopts an assembled design, greatly enhancing the heat dissipation efficiency of the flat die. At the same time, it can also facilitate local maintenance of the flat die, greatly increasing the utilization rate of the flat die and being beneficial to cost saving.
