Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT

[0025] Please refer to Figures 1-10 The present application provides the following technical solutions: a granule preparation device, comprising a device box 1, a driving structure installed inside the device box 1, a granulation box body structure installed on the upper end face of the device box 1, the driving structure being inserted in the granulation box body structure to realize granulation work, a limiting flow being further installed in the granulation box body structure, and a moving structure for stirring up and down being further installed in the granulation box body structure, the moving structure comprising a top mounting plate 6, an air cylinder 7, a sleeve 8, a sealing bearing 9, a limiting plate 10, and a stirring rod 11; the top mounting plate 6 is installed on the upper end of the granulation box body structure, the air cylinder 7 is installed on the upper end face of the top mounting plate 6 and has a telescopic end extending downward through the top mounting plate 6 into the granulation box body structure, the sealing bearing 9 is installed at the upper end of the inner surface of the sleeve 8, the inner ring of the sealing bearing 9 is connected with the telescopic end, recesses are symmetrically formed on the inner surface of the sleeve 8, the sleeve 8 is in contact with the driving structure, the limiting plate 10 is installed on the outer surface of the sleeve 8, and the stirring rod 11 is further installed on the lower side of the limiting plate 10 close to the surface of the sleeve 8.

[0026] In the present embodiment, the specific working principle is as follows: when the device is started, the material is extruded out of the granulation box body structure in an extrusion manner through the action of the driving structure, so as to produce granular material. In order to prevent a large amount of material from adhering to the inside of the granulation box body structure due to accumulation, thereby reducing the granulation efficiency, the sleeve 8 is driven to move up and down by the air cylinder 7, and the sleeve 8 is driven to rotate by the driving structure through the action of the sealing bearing 9, and the sealing bearing 9 can prevent the material from directly entering the sleeve 8. At this time, the sleeve 8 rotates and moves up and down, and the limiting plate 10 (see Figure 3Visible) can limit the flow of material, prevent a large amount of material from entering the granulation box structure directly at a moment, specifically when the limiting plate 10 moves downward, the distance between the limiting plate 10 and the inner side of the granulation box structure is reduced, so the amount of material entering can be reduced, only when the limiting plate 10 moves upward, most of the material can fall, in this way, the amount of material entering can be effectively controlled, so as to prevent the material from accumulating in the granulation box structure and causing poor particle preparation efficiency, and when the material falls, the material block adhered together can be crushed by the action of the stirring rod 11, so as to prevent the material from falling in block shape and affect the particle preparation efficiency, thereby solving the problem that the existing particle preparation equipment cannot control the amount of material entering while stirring, so as to effectively improve the particle preparation efficiency and prevent the problem of adhesion from occurring, and facilitating subsequent cleaning.

[0027] According to the above, wherein the granulation box structure can specifically refer to Figure 1 And Figure 3 Visible, the granulation box structure includes a granulation box 2, a feeding plate 3, a protective shell 4, and a feeding hopper 5; the granulation box 2 is bolted to the upper end face of the device box 1, the outer surface of the granulation box 2 is sequentially provided with the feeding plate 3 and the protective shell 4 from bottom to top, the upper end of the granulation box 2 is provided with the feeding hopper 5, the upper end of the feeding hopper 5 is provided with the top mounting plate 6, the surface of the granulation box 2 is provided with a hole, by rotating the driving structure, the material can be extruded, then extruded from the hole in the surface of the granulation box 2, so as to realize particle preparation, the prepared particles fall onto the feeding plate 3 for unified collection, and then in order to prevent the particles from splashing when extruding from the hole, the protective shell 4 is used for protection.

[0028] In order to prevent the limiting plate 10 from being stuck with the inner surface of the granulation box 2 when it moves downward, specifically refer to Figure 3 Visible, the diameter of the limiting plate 10 is smaller than the diameter of the inner cavity of the granulation box 2 at the middle, and the cross section of the limiting plate 10 is a triangular pyramid.

[0029] The driving structure can specifically refer to Figure 3 And Figure 9It can be seen that the driving structure comprises a first mounting frame 12, a servo motor 13, a second mounting frame 14, a pulley 15, a transmission belt 16, a rotating shaft 17 and a granulating roller 18. The first mounting frame 12 and the second mounting frame 14 are both mounted on the inner bottom end face of the device box 1. The servo motor 13 is mounted on the upper end of the first mounting frame 12, and the pulley 15 is connected to the output end of the servo motor 13. The bearing seat is mounted on the upper end of the second mounting frame 14, and the inner ring is connected to the rotating shaft 17. The pulley 15 is mounted on the lower end of the rotating shaft 17. The transmission belt 16 is wound between the two pulleys 15. The rotating shaft 17 extends upward into the granulating box 2. The granulating roller 18 is mounted on the surface of the rotating shaft 17 in the granulating box 2. The upper end of the rotating shaft 17 is also symmetrically provided with a protrusion which is inserted into the groove in the inner side of the sleeve 8. The servo motor 13 drives the pulley 15 to rotate, thereby realizing the rotation of the rotating shaft 17 through the transmission belt 16. After rotation, the granulating roller 18 is driven to rotate, realizing the extrusion of the material in the inner surface of the granulating box 2 through the hole.

[0030] In order to further disturb the material, please refer to Figure 6 and Figure 7 It can be seen that the upper end face of the granulating roller 18 is also provided with an arc-shaped plate 19. Even if a large amount of material appears in the interior of the granulating box 2, it can also be stirred by the arc-shaped plate 19 to prevent the occurrence of adhesion phenomenon. And due to the effect of the moving structure, when the stirring rod 11 performs the first layer stirring, the arc-shaped plate 19 further stirs to realize the crushing of the material, thereby facilitating the particle preparation efficiency of the granulating roller 18.

[0031] Working principle: in use, the limiting plate 10 is located at the connection between the granulating box 2 and the feeding hopper 5. Then the material is poured into the feeding hopper 5, and then the device is started. At this time, the servo motor 13 drives the rotating shaft 17 to rotate through the pulley 15 and the transmission belt 16. At this time, the rotating shaft 17 in the granulating box 2 drives the granulating roller 18 to rotate. Then the cylinder 7 is started to drive the sleeve 8 to move up and down, and the sleeve 8 is rotated by the rotating shaft 17, thereby realizing the crushing of the falling material by the stirring rod 11, thereby preventing the material from forming a group. Therefore, the limiting plate 10 realizes the control of the amount of material entering, preventing a large amount of material from entering the granulating box 2 and causing adhesion phenomenon, thereby reducing the efficiency of particle preparation. After the material falls from the limiting plate 10 to the granulating roller 18, it is crushed again by the arc-shaped plate 19, thereby effectively improving the extrusion of the material by the granulating roller 18, which helps to improve the granulation efficiency. Then the material is extruded through the hole in the surface of the granulating box 2 and falls onto the discharging plate 3 for collection.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
