[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example:
[0029] Please see Figure 1 - Figure 4 In this embodiment, a powder granulator grinding disc with a cleaning device includes a granulator grinding disc 1 and a cleaning plate 2 disposed above the granulator grinding disc 1. The lower surface of the cleaning plate 2 is provided with a plurality of cleaning feet 3, which are adapted to the holes opened on the granulator grinding disc 1.
[0030] A rotating shaft 4 is fixedly connected to the upper end of the cleaning plate 2. A lower meshing tooth 5 is arranged in a ring on the outer side of the rotating shaft 4. The rotating shaft 4 is connected to a meshing ring 11 through the lower meshing tooth 5. A support ring 10 is arranged at the upper end of the meshing ring 11. A rotating disk 9 is arranged inside the support ring 10. A circular groove is opened at the same horizontal position as the rotating disk 9 and the support ring 10. A rotation limiting ring 6 is rolled in the circular groove. The rotation limiting ring 6 is sleeved on the outer side of the rotating shaft 4.
[0031] The upper half of the outer side of the rotating shaft 4 is provided with an upper meshing tooth 7, which meshes with a drive gear 8. The upper end of the drive gear 8 is fixedly connected to a rotating motor 12, and the upper end of the rotating motor 12 is fixedly connected to a support cylinder 14. A buffer assembly is connected inside the support cylinder 14, and a connecting arm 18 is fixedly connected to the upper end of the buffer assembly. An elastic rotating assembly is provided at the end of the connecting arm 18 away from the buffer assembly.
[0032] First, the holes on the granulator grinding disc 1 are evenly arranged. Then, the holes on the granulator grinding disc 1 are imprinted. The position of the cleaning foot 3 is set accordingly according to the specifications of the imprinted hole distribution. By setting the cleaning foot 3 on the cleaning plate 2 to the same installation method as the hole distribution position on the granulator grinding disc 1, the cleaning plate 2 and the cleaning foot 3 can be inserted into the holes on the granulator grinding disc 1 when they move down, thereby passively moving the material blocking the inside of the hole down, achieving the effect of quickly cleaning the holes on the granulator grinding disc 1.
[0033] With the support of the elastic rotating component, the cleaning plate 2, cleaning foot 3 and the upper part can be rotated and adjusted at the same time, which can facilitate the position adjustment when cleaning or not in use. With the combined use of the buffer component, both ends of the connecting arm 18 have elastic buffer, so that the cleaning plate 2 has the effect of automatic reset and pressing buffer when it is pressed down and moved.
[0034] Under the drive of the rotating motor 12, the active gear 8 is driven to rotate simultaneously. Under the meshing transmission of the active gear 8 and the upper meshing gear 7, and under the limiting guidance of the support ring 10 and the inner groove of the rotating disk 9, the cleaning plate 2 and the cleaning foot 3 can rotate with the center point of the rotating disk 9 as the center, thereby adjusting the position of the cleaning foot 3.
[0035] Under the meshing transmission between the lower meshing teeth 5 and the inner wall of the meshing ring 11, the rotating shaft 4 can rotate synchronously, thereby readjusting the angle of the cleaning foot 3. Combined with the rotation of the connecting arm 18, it is convenient to readjust the cleaning foot 3. In addition, the granulator grinding disc 1 itself has a rotating effect during use, ensuring that the cleaning foot 3 can be inserted into the inner hole of the granulator grinding disc 1 for cleaning when used in different positions.
[0036] The drive gear 8 is fixedly mounted on the output end of the rotating motor 12. The drive gear 8 is fixedly connected to the rotating disk 9. A support disk 13 is fixedly sleeved on the outside of the rotating motor 12. The support disk 13 is fixedly connected to the support ring 10 by bolts.
[0037] The inner wall of the meshing ring 11 is provided with a meshing groove that is compatible with the lower meshing teeth 5;
[0038] By connecting and securing the support plate 13, the meshing ring 11, and the bolts, and by connecting and positioning the rotating motor 12, the stability of the outer side of the internal drive gear 8 and the cleaning plate 2 is ensured when they rotate. Furthermore, by opening corresponding meshing grooves on the inner wall of the meshing ring 11, the stability of the cleaning plate 2 and the cleaning foot 3 in rotating when the remaining lower meshing teeth 5 mesh and drive are ensured.
[0039] The buffer assembly consists of a buffer spring 15, a buffer shell 16, and a limiting bolt 17. The buffer shell 16 is sleeved on the outside of the support cylinder 14. The upper end of the buffer spring 15 is located on the upper surface of the inner wall of the buffer shell 16, and the lower end of the buffer spring 15 is located on the bottom surface inside the support cylinder 14.
[0040] The limiting bolt 17 is fixedly connected to the lower end of the support cylinder 14, the limiting bolt 17 is slidably connected to the buffer shell 16, and the limiting bolt 17 extends out of the outer side of the buffer shell 16.
[0041] First, by using a buffer spring 15 of a certain strength, its elastic strength is greater than the weight of the support cylinder 14 and the lower part, and by setting a fastening nut at the upper end of the limit bolt 17, the effect of limiting the connection between the support cylinder 14 and the buffer shell 16 is achieved.
[0042] By pressing the connecting arm 18, the buffer shell 16 and the support cylinder 14 move down synchronously. After the cleaning foot 3 is inserted into the hole below, the connection is made. By continuously pressing the connecting arm 18, when the cleaning foot 3 touches the bottom, the buffer shell 16 will continue to be pressed down under the elastic action of the buffer spring 15, thereby achieving the buffering effect.
[0043] The upper surface of the buffer shell 16 is fixedly connected to one end of the connecting arm 18. The elastic rotating assembly includes a fixed base 19 that is inserted into the connecting arm 18. The connecting arm 18 is inserted into the fixed base 19. A limiting plate 20 for limiting support is fixedly connected to the lower end of the connecting arm 18.
[0044] The elastic rotation assembly also includes a limiting sleeve 22 and a limiting outer ring 23 for rotation limiting. The limiting outer ring 23 is fixedly sleeved on the outside of the connecting arm 18. A number of connecting springs 21 are provided at the lower end of the limiting sleeve 22. The lower end of the connecting springs 21 is provided on the upper surface of the fixed base 19. The limiting outer ring 23 is rotatably disposed inside the limiting sleeve 22.
[0045] When the connecting arm 18 is pressed, under the elastic support of the connecting spring 21 and the fixed support of the limiting outer ring 23 and the connecting arm 18, the connecting arm 18 moves down, causing the limiting sleeve 22 to move down synchronously, thus pressing the connecting spring 21 and causing it to contract. Under the limit of the limiting plate 20, the connecting arm 18 is prevented from moving beyond the limit when it is reset. At the same time, the reliability of the support position of the fixed base 19 and the connecting arm 18 is ensured. The fixed base 19 is fixedly or movably set on the side of the granulator grinding disc 1 for processing. The specific connection and placement of the fixed base 19 can be selected according to the actual situation.
[0046] When the connecting arm 18 rotates, the rotational connection between the limiting outer ring 23 and the limiting sleeve 22, as well as the limiting, ensure the reliability of the rotation angle of the connecting arm 18 and the stability of its connection.
[0047] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
