[0019] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] Example

[0021] refer to Figures 1 to 4A granulation device for fiber production with adjustable particle size includes a frame 1 and a forming cylinder 2 mounted on the frame 1. A hopper 21 for feeding is provided on the forming cylinder 2. An extrusion screw 22 is rotatably mounted inside the forming cylinder 2. An extrusion motor 221 and its reducer are connected to the extrusion screw 22 for driving its rotation. A fixed discharge plate 23 is provided at the output end of the forming cylinder 2. A movable discharge plate 24 is fitted onto the fixed discharge plate 23. Several primary discharge ports 231 are evenly distributed around the center of the fixed discharge plate 23. The movable discharge plate 24 is rotatably mounted on the forming cylinder 2. The movable discharge plate 24 is provided with an adjustment handle 242 extending radially outward, providing convenience for the operator. The operation is simple and convenient. The position of the movable discharge plate 24 can be adjusted directly by rotating the adjustment handle 242, thereby changing the overlapping area of ​​the primary discharge port 231 and the secondary discharge port 241, and realizing the rapid adjustment of the granulation hole 25. The operation is simple, convenient and quick, without the need for complicated tools or equipment. Several secondary discharge ports 241 are evenly opened along the center of the movable discharge plate 24. The primary discharge port 231 and the secondary discharge port 241 are both strip-shaped hole structures. Each primary discharge port 231 and each secondary discharge port 241 corresponds one-to-one. The overlapping opening areas form the granulation hole 25 for material output. A cutting disc 26 for material cutting is rotatably arranged on the frame 1 located outside the movable discharge plate 24. A cutting motor 261 is connected to the cutting disc 26 to drive its rotation to realize the cutting action. This technical solution forms a granulation hole 25 by overlapping the primary discharge port 231 on the fixed discharge plate 23 and the secondary discharge port 241 on the movable discharge plate 24. The movable discharge plate 24 is rotatable, which can flexibly adjust the overlap area of ​​the primary discharge port 231 and the secondary discharge port 241, thereby changing the size of the granulation hole 25. This allows for adjustable particle size in fiber production, meets different production needs, and improves the versatility and adaptability of the device. The extrusion screw 22, fixed discharge plate 23, movable discharge plate 24, cutting disc 26, and other components are integrated on the frame 1 and forming cylinder 2. The overall layout is compact, occupies a small area, and is easy to operate and maintain. At the same time, the close cooperation between the components ensures the stability and efficiency of the granulation process.

[0022] Structurally, a protective cover 27 is provided on the outside of the forming cylinder 2 on one side of the cutting disc 26. The protective cover 27, covering the forming cylinder 2 on one side of the cutting disc 26, effectively prevents splashes or fragments generated by the cutting disc 26 during high-speed operation from injuring operators and surrounding equipment, improving equipment safety and ensuring the safety of personnel and equipment on the production site. During the cutting process, some dust may be generated; the protective cover 27 can confine the dust within a certain range, reducing its diffusion to the surrounding environment, minimizing its impact on operator health and production equipment, and improving air quality in the working environment. The protective cover 27 also provides some sound insulation, reducing the noise generated by the cutting disc 26 during operation and providing operators with a relatively quiet working environment, which helps improve work efficiency and quality.

[0023] Structurally, the secondary discharge port 241 has an extension ring 243 extending along the edge of the secondary discharge port 241 on one side surface near the cutting disc 26. The extension ring 243, located on the side surface of the secondary discharge port 241 near the cutting disc 26 and extending along the edge of the secondary discharge port 241, can support particles not cut by the cutting disc 26, preventing deformation or damage due to uneven force during cutting, thus ensuring particle integrity and quality. During cutting, the extension ring 243 provides a stable support surface for the particles, allowing them to be cut more smoothly under the action of the cutting disc 26, reducing particle swaying or deviation during cutting, improving cutting stability and precision, and thus ensuring the consistency of particle size and shape.

[0024] Furthermore, due to the supporting effect of the extended ring 243 on the particles, the impact and wear of the particles on the cutting disc 26 are reduced, the wear rate of the cutting disc 26 is reduced, the service life of the cutting disc 26 is extended, and the maintenance cost of the equipment is reduced.

[0025] In this embodiment, the forming cylinder 2 located at the secondary discharge port 241 has several cooling water holes 28 for connecting cooling water. Water flows from these holes 28 and acts on the extension ring 243. The cooling water flowing through the cooling water holes 28 and acting on the extension ring 243 rapidly conducts heat away from the extension ring 243, quickly cooling the granules extruded from the secondary discharge port 241. Rapid cooling helps to shape the granules, preventing deformation or sticking due to excessive temperature in subsequent processes, thus ensuring the shape and quality of the granules. Rapid cooling shortens the cooling time of the granules, allowing them to reach a collectable state more quickly, thereby accelerating the production speed of the entire granulation process and improving production efficiency. By removing heat with cooling water, the temperature near the forming cylinder 2 is reduced, improving the working environment for operators and also helping to reduce the risk of equipment failure due to high-temperature operation, thus improving the operational stability of the equipment.

[0026] In this embodiment, a collection bucket 3 is installed on the lower frame 1 of the cutting disc 26. The collection bucket 3 contains a collection liquid to prevent particle adhesion. The collection liquid in the collection bucket 3 can buffer and protect the particles cut by the cutting disc 26, preventing them from breaking or deforming due to collision during the fall, ensuring the integrity of the particles and improving the product qualification rate. The collection liquid is usually tap water. It can effectively prevent particles from sticking together in the collection bucket 3, allowing the particles to maintain a good dispersion state, which is convenient for subsequent collection, packaging and use. At the same time, preventing adhesion also helps to keep the collection bucket 3 clean, reducing the difficulty and frequency of cleaning. The setting of the collection bucket 3 provides a centralized collection area for the particles, so that the particles can be collected smoothly, avoiding the particles from scattering around the equipment or on the ground, reducing material waste, and also facilitating the subsequent processing and transportation of the particles.
