Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a rolling die structure of a fertilizer granulator. Background Art

[0002] A granulator is a device used to press powdered or granular raw materials into granular or block products. It is usually used in the pharmaceutical, chemical, food processing and other industries. Granulators are divided into flat die granulators and roller die granulators according to the structure of the template. The roller die granulator is also called a ring die granulator.

[0003] For example, a ring die for a granulator disclosed in the authorization announcement number CN212701814U includes a ring die sleeve, a straight hole is provided on the ring die sleeve, and the straight holes are provided in a plurality, and the plurality of straight holes are arranged in a circle with the center of the ring die sleeve as the center, and a release-type stepped hole is provided at the rear end of the straight hole, and the setting structure of the release-type stepped hole is consistent with the setting of the straight hole. After adopting the above technical scheme, the beneficial effect of the utility model is as follows: through the setting of straight holes, release-type stepped holes, compression-type stepped holes, outer tapered holes and inner tapered holes, when the user uses the ring die for the granulator, the user can solve the problem of short service life of the ring die caused by severe wear or rupture during use by optimizing the compression ratio of the ring die and the straight holes, release-type stepped holes, compression-type stepped holes, outer tapered holes and inner tapered holes.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] Although the above patent can solve the problem of short service life of the ring die due to severe wear or breakage during use, the irregular arrangement of straight holes, release-type stepped holes, compression-type stepped holes, outer tapered holes and inner tapered holes arranged thereon makes it impossible to control the size of the fertilizer particles according to demand during granulation. Utility Model Content

[0015] Preferably, the outer movable sleeve of the guide rod is provided with a spring, and two ends of the spring are respectively fixedly connected to the movable plate and the chassis.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. A roller die structure of a fertilizer granulator is used in conjunction with a roller die body, a movable disk, a die hole and a conduit. When particles of different specifications need to be processed, the conduit is controlled to move to one side of the roller die body. When the conduit moves, it pushes the pressure roller and the movable disk forward, so that the movable disk moves toward the inside of the roller die body. At the same time, the conduit blocks the die hole at the front end of the roller die body, so that fertilizer particles of another specification can be made through the die hole in the middle of the roller die body. In this way, during processing, there is no need to replace roller die bodies of different models, and only the position of the movable disk needs to be adjusted.

[0018] 2. This kind of fertilizer granulator rolling die structure is used in conjunction with a guide rod, a spring, a movable disk and a guide tube. When the movable disk needs to be controlled to reset to the initial point, the guide tube is controlled to move outward. At this time, the compressed springs at both ends of the other side of the movable disk will rebound at the same time. The rebound force of the spring controls the movable disk to move outward synchronously until it is reset to the initial point. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A roller die structure for a fertilizer granulator comprises a chassis 1, a roller die body 2 is integrally formed on one side of the chassis 1, a movable disk 3 is movably installed inside the roller die body 2, and an extrusion mechanism is arranged in the middle of the movable disk 3; a plurality of regularly arranged die holes 4 are arranged in sequence from left to right on the inner and outer sides of the roller die body 2, and the aperture sizes of the plurality of die holes 4 increase in sequence from left to right; a guide tube 5 is movably sleeved on the side of the roller die body 2 away from the chassis 1; the extrusion mechanism comprises a motor 6, a swing arm 7 and a pressure roller 8, the motor 6 is fixedly installed on the middle part of one side of the movable disk 3 close to the chassis 1, the output shaft of the motor 6 passes through the movable disk 3 and is fixedly installed with the swing arm 7, both ends of the swing arm 7 are fixedly connected to the pressure roller 8, and the outer walls of the two pressure rollers 8 are both provided with diagonal grooves;

[0027] In this embodiment, during processing, the material is put in from the front of the conduit 5, and then the motor 6 on the other side of the movable disk 3 is started. The motor 6 controls the swing arm 7 on the front side of the movable disk 3 to rotate. When the swing arm 7 rotates, the fertilizer raw materials entering therein are squeezed from the inside of the roller mold body 2 through the pressure roller 8 until the raw materials pass through the die hole 4 and become granular. When particles of different specifications need to be processed, the conduit 5 is controlled to move to one side of the roller mold body 2. When the conduit 5 moves, it pushes the pressure roller 8 and the movable disk 3 forward, so that the movable disk 3 will move to the inside of the roller mold body 2. At the same time, the conduit 5 will block the die hole 4 at the front end of the roller mold body 2, so that fertilizer particles of another specification can be made through the die hole 4 in the middle of the roller mold body 2. In this way, during processing, there is no need to replace different types of roller mold bodies 2, and only the position of the movable disk 3 needs to be adjusted.

[0028] like Figure 2 and Figure 3 As shown, the four outer sides of the roller mold body 2 are all provided with side grooves 9, the inner wall of the guide tube 5 close to the roller mold body 2 is provided with an annular groove 10, and the inner wall of the annular groove 10 is symmetrically provided with side blocks 11 on both sides, the side blocks 11 are slidably connected with the side grooves 9, and the annular groove 10 is movably fitted with the roller mold body 2;

[0029] In this embodiment, when the conduit 5 moves, the annular groove 10 inside the conduit 5 will be inserted along one end of the roller mold body 2, and at the same time, the side block 11 slides along the inside of the side groove 9 for guidance.

[0030] like Figure 4 As shown, both ends of the chassis 1 are penetrated with rod grooves 12, and guide rods 13 are symmetrically arranged at both ends of one side of the movable plate 3 close to the rod groove 12, and the guide rod 13 is movably sleeved with the rod groove 12, and a spring 14 is movably sleeved outside the guide rod 13, and the two ends of the spring 14 are fixedly connected to the movable plate 3 and the chassis 1 respectively;

[0031] In this embodiment, when it is necessary to control the movable disk 3 to reset to the initial point, the control guide tube 5 is moved outward. At this time, the springs 14 compressed at both ends of the other side of the movable disk 3 will rebound at the same time. The rebound force of the springs 14 controls the movable disk 3 to move outward synchronously until it is reset to the initial point.

[0032] Working principle: During processing, the material is put in from the front of the conduit 5, and then the motor 6 on the other side of the movable disk 3 is started. The motor 6 controls the swing arm 7 on the front side of the movable disk 3 to rotate. When the swing arm 7 rotates, the fertilizer raw materials entering therein are squeezed from the inside of the roller mold body 2 through the pressure roller 8 until the raw materials pass through the die hole 4 and become granular. When particles of different specifications need to be processed, the conduit 5 is controlled to move to one side of the roller mold body 2. When the conduit 5 moves, it pushes the pressure roller 8 and the movable disk 3 forward, so that the movable disk 3 will move into the inside of the roller mold body 2. At the same time, the conduit 5 will block the die hole 4 at the front end of the roller mold body 2, so that fertilizer particles of another specification can be made through the die hole 4 in the middle of the roller mold body 2.
