Technical Field

[0001] This utility model relates to the field of granulator drums, and more particularly to a drum structure for a granulator. Background Technology

[0002] The textile fleece mill is a core piece of equipment used in the textile industry to produce fleece. It uses mechanical action to curl the disordered fluff on the surface of the fabric into granules, and high-frequency vibration causes the granular material to tumble and jump on the screen surface, achieving stratified screening by utilizing the density differences of different particles.

[0003] Chinese patent CN210712186U discloses a granulator. This technical solution, through the setting of circulating pipelines and circulating fans, can realize the recycling of heating gas, reduce gas heating time, improve drying efficiency, and reduce energy consumption.

[0004] However, the roller structure of this granulator has a problem: during the granulation process, the lint and fibers on the surface of the fabric can clog the openings on the roller surface. It does not have an automatic cleaning function for the openings, which will affect the drying effect when the hot air flows, thus hindering the granulation of the fabric.

[0005] Therefore, it is necessary to provide a drum structure for a pellet mill to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a drum structure for a granulator, which solves the problem that the drum structure of the granulator does not have an automatic cleaning function for the inlet, which will cause the drying effect when the hot airflow is flowing, which is not conducive to the use of fabric granulation.

[0007] To solve the above-mentioned technical problems, the present invention provides a drum structure for a granulator, comprising two mounting plates, with a drum body rotatably disposed between the two mounting plates. The surface of the drum body has several openings. A fixing plate is fixedly connected to the side wall of the mounting plates. A receiving box is fixedly connected between the two fixing plates. A moving box that moves horizontally is disposed on the inner side of the receiving box via a transmission mechanism. A central control arc plate that moves vertically is disposed on the upper and lower parts of the inner side of the moving box. A hair suction port is disposed on the inner side of the central control arc plate. Several brushes are fixedly connected to the lower surface of the central control arc plate.

[0008] Preferably, the inner wall surface of the mounting plate is fixedly connected with a plurality of protrusions, and the plurality of protrusions are evenly spaced and distributed in a ring along the inner wall surface of the mounting plate.

[0009] Preferably, one end of the sidewall of the mounting plate is fixedly connected to a drive gear that is connected to an external drive device.

[0010] Preferably, the transmission mechanism includes a threaded rod, a motor, and a threaded sleeve. The threaded rod is rotatably disposed within the inner cavity of the receiving box. The motor is fixedly connected to one end face of the receiving box. The other end of the threaded rod extends to the outside of the receiving box and is fixedly connected to the output shaft of the motor. The threaded sleeve is threadedly connected to the surface of the threaded rod. A connecting rod is fixedly connected to the inner side of the threaded sleeve. The other end of the connecting rod extends movably to the outside of the receiving box and is fixedly connected to the outer side of the movable box.

[0011] Preferably, the inner side of the receiving box has a first movable opening for the connecting rod to move.

[0012] Preferably, a bidirectional electric telescopic rod is vertically fixedly connected to the middle of the inner cavity of the mobile box. A horizontal plate is fixedly connected to both the top and bottom of the bidirectional electric telescopic rod. The other end of the horizontal plate extends movably to the outside of the mobile box and is fixedly connected to the surface of the corresponding central control arc plate. A vertical pipe is connected to the outer side of the central control arc plate, and a flange is provided at the other end of the vertical pipe.

[0014] Compared with related technologies, the drum structure of the granulator provided by this utility model has the following beneficial effects:

[0015] This utility model provides a drum structure for a granulator. During the rolling process, multiple brushes clean the surfaces of multiple openings on the drum body. Simultaneously, a transmission mechanism drives a central control arc plate to move along the length of the mounting plate, thoroughly cleaning the mounting plate surface. This prevents lint fibers from clogging the openings, improves the smoothness of hot airflow into the drum body's internal cavity, and enhances the drying of the fabric during granulation. Furthermore, during cleaning, by drawing airflow from the central control arc plate, a negative pressure is created inside, which then draws out the cleaned lint fibers through the suction port for centralized collection, facilitating subsequent recycling.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] First Embodiment

[0023] Please refer to the following: Figure 1 , Figure 2 and Figure 4 The drum structure of the granulator includes two mounting plates 1, with a drum body 2 rotatably mounted between the two mounting plates 1. The surface of the drum body 2 has several openings 3. A fixing plate 6 is fixedly connected to the side wall of the mounting plate 1, and a receiving box 7 is fixedly connected between the two fixing plates 6.

[0024] The inner side of the container 7 is provided with a movable box 13 that moves horizontally via a transmission mechanism. The upper and lower parts of the inner side of the movable box 13 are provided with a central control arc plate 17 that moves vertically. The inner side of the central control arc plate 17 is provided with a hair suction port 18. Several brushes 19 are fixedly connected to the lower surface of the central control arc plate 17.

[0025] In this embodiment, during the rolling process, the roller body 2 can be cleaned by brushing the surfaces of multiple openings 3 on the surface of the roller body 2 with multiple brushes 19. During the brushing and cleaning process, the central control arc plate 17 is moved along the length direction of the surface of the mounting plate 1 by the transmission mechanism.

[0026] A thorough cleaning of the surface of the mounting plate 1 is performed to prevent lint fibers from clogging the surface of the inlet 3, thereby improving the smoothness of hot airflow entering the inner cavity of the drum body 2 and thus improving the drying of the fabric during the shredding process.

[0027] During the cleaning process, by drawing airflow from the central control arc plate 17, a negative pressure is generated inside the central control arc plate 17, which then draws out the cleaned lint fibers through the lint suction port 18 and collects the lint fibers for subsequent recycling.

[0028] The inner wall of the mounting plate 1 is fixedly connected with several protrusions 4. The multiple protrusions 4 are evenly distributed in a ring along the inner wall of the mounting plate 1. One end of the side wall of the mounting plate 1 is fixedly connected with a drive gear 5 that is connected to an external drive device.

[0029] The raised strip 4 enhances the kneading effect on the fabric during the rotation of the roller body 2, thereby improving the quality of the pelletizing process and facilitating the use of the fabric pelletizing process.

[0030] Second Embodiment

[0031] Please refer to the following: Figure 3 Based on the same concept as the first embodiment described above, the transmission mechanism includes a threaded rod 9, a motor 8, and a threaded sleeve 10. The threaded rod 9 is rotatably disposed in the inner cavity of the receiving box 7. The motor 8 is fixedly connected to one end face of the receiving box 7. The other end of the threaded rod 9 extends to the outside of the receiving box 7 and is fixedly connected to the output shaft of the motor 8. The threaded sleeve 10 is threadedly connected to the surface of the threaded rod 9.

[0032] A connecting rod 12 is fixedly connected to the inner side of the threaded sleeve 10. The other end of the connecting rod 12 extends movably to the outside of the receiving box 7 and is fixedly connected to the outer side of the movable box 13. A first movable opening 11 for the connecting rod 12 to move is opened laterally on the inner side of the receiving box 7.

[0033] In this embodiment, after the motor 8 drives the threaded rod 9 to rotate, the threaded sleeve 10 can move along the surface of the threaded rod 9. Then, by using the connection of the connecting rod 12, the movable box 13 can be moved.

[0034] Third Embodiment

[0035] Please refer to the following: Figure 1 , Figure 2 and Figure 4 Based on the same concept as the first embodiment described above, a bidirectional electric telescopic rod 14 is vertically fixedly connected to the middle of the inner cavity of the mobile box 13. A horizontal plate 15 is fixedly connected to the top and bottom of the bidirectional electric telescopic rod 14. The other end of the horizontal plate 15 extends movably to the outside of the mobile box 13 and is fixedly connected to the surface of the corresponding central control arc plate 17. A vertical pipe 20 is connected to the outer side of the central control arc plate 17. A flange 21 is provided at the other end of the vertical pipe 20. The upper and lower parts of the inner side of the mobile box 13 are vertically opened with second movable openings 16 for the horizontal plate 15 to move.

[0036] In this embodiment, after the bidirectional electric telescopic rod 14 extends and retracts, the distance between the two central control arc plates 17 can be adjusted. Thus, during the operation of the mounting plate 1 shaking pellets, the two central control arc plates 17 are driven to move away from each other. In the process of not cleaning, the brush 19 is kept out of contact with the surface of the roller body 2, reducing the wear rate of the brush 19 and extending the service life of the brush 19.

[0037] The working principle of the drum structure of the granulator provided by this utility model is as follows:

[0038] During the rolling process, the roller body 2 can be cleaned by brushing the surfaces of multiple openings 3 on the surface of the roller body 2 with multiple brushes 19. During the brushing process, the central control arc plate 17 is moved along the length direction of the surface of the mounting plate 1 by the transmission mechanism, so that the surface of the mounting plate 1 can be thoroughly cleaned.

[0039] Compared with related technologies, the drum structure of the granulator provided by this utility model has the following beneficial effects:

[0040] During the rolling process of the roller body 2, multiple brushes 19 clean the surfaces of multiple openings 3 on the roller body 2. During the brushing process, the transmission mechanism drives the central control arc plate 17 to move along the length of the mounting plate 1, thus thoroughly cleaning the surface of the mounting plate 1. This prevents lint fibers from clogging the surfaces of the openings 3, improves the smoothness of hot airflow into the inner cavity of the roller body 2, and enhances the drying of the fabric during the shaking process. Furthermore, during the cleaning process, by drawing airflow from inside the central control arc plate 17, a negative pressure is generated inside the central control arc plate 17, which then draws out the cleaned lint fibers through the lint suction port 18 for centralized collection, facilitating subsequent recycling.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
