Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a grinding device for processing polygonatum raw materials. Background Art

[0002] Polygonatum sibiricum is a traditional Chinese medicine, and its main effects include clearing away heat and detoxifying, replenishing deficiency and invigorating qi, calming the nerves and calming convulsions, etc. Polygonatum sibiricum contains a variety of active ingredients, such as polygonatin, polygonatin alcohol, and polygonatinone, which have antioxidant, anti-inflammatory, and anti-tumor effects.

[0003] In order to improve the absorption effect of active ingredients, it is necessary to grind Polygonatum into powder. In the existing grinding device, after the Polygonatum raw material is put into the grinding bin for grinding, the raw material enters the grinding chamber from the feeding port at the upper end of the grinding seat for grinding. In order to ensure the adequacy of grinding, the feeding port at the upper end of the grinding seat is as narrow as the grinding chamber space, and the feeding port space cannot be adjusted. Since the Polygonatum put in is large in size in the initial state, it is difficult to quickly roll it into the grinding chamber from the feeding port, and it takes a certain amount of time. Therefore, during the grinding process, in order to avoid blockage at the feeding place of the grinding seat, it is generally necessary to slowly feed the material into the grinding bin, which results in the inability to improve the material grinding efficiency. Therefore, there is an urgent need for a grinding device for processing Polygonatum raw materials. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a grinding device for processing Polygonatum sibiricum raw materials, which is used to solve the problem that the material is limited by the fixed space of the feeding port of the grinding seat, resulting in a long waiting time for the material to be drawn into the grinding chamber for grinding, resulting in the inability to improve the material grinding efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Combination Figure 1-Figure 4 As shown, the utility model provides: a grinding device for processing polygonatum raw material, including a grinding box 1 made of stainless steel, a grinding table 2 for grinding polygonatum is installed inside the grinding box 1, and a discharge mechanism 3 for discharging the ground material is connected to the bottom of the grinding table 2, the grinding table 2 is composed of a first body 201 fixed on the inner wall of the upper end of the grinding box 1 and a second body 202 that can move up and down relative to the first body 201, and a grinding cavity is formed between the two, and the first body 201 is also equipped with grinding balls for grinding the polygonatum material.

[0026] In order to solve the problem that the grinding chamber gap between the first platform 201 and the second platform 202 in the traditional grinding device cannot be adjusted, the present invention is to install a driving mechanism 4 for driving the second platform 202 up and down on the bottom inner wall of the grinding box 1, and the specific structure includes a driving roller 401 rotatably installed under the second platform 202, and the surface of the driving roller 401 is installed with a recessed area 401a, and the height difference between the surface of the recessed area 401a and the outer wall of the rotating roller is 8mm, and one end of the rotating roller is connected to a gear set 402, and the gear set 402 is composed of a gear 1 and a gear 2 with different diameters and rotating with each other, and the gear 1 is connected to one end of the rotating roller, and one end of the gear 2 is connected to a motor 1 403, and the top of the driving roller 401 is movably connected with a driving plate 404 for driving the second platform 202 to move upward, and the bottom of the driving plate 404 is installed with four telescopic units 405, 03 When the rotating roller is driven to rotate by the gear set 402, different from the traditional cylindrical driving roller 401, the driving roller 401 in this scheme has a recessed area 401a on its surface. Since the driving plate 404 above is always in contact with the surface of the rotating roller, when the recessed area 401a on the surface of the rotating roller rotates to contact with the driving plate 404, the driving plate 404 will move slightly downward by a certain distance under the action of gravity and the spring. At this time, the second platform 202 in contact with the upper surface of the driving plate 404 will also move downward, thereby expanding the grinding chamber gap between the first platform 201 and the second platform 202, so that the material originally at the upper port of the grinding chamber can enter the grinding chamber more smoothly, reducing the risk of blockage at this position, and because the rotating roller is always rotating, the grinding chamber is expanded into a cyclic and short process, ensuring repeated grinding while accelerating the material to enter the grinding chamber, effectively improving the overall grinding efficiency.

[0027] In order to solve the problem of excessive friction when the top of the driving plate 404 contacts the bottom of the second platform 202, a number of guide balls are movably installed on the surface of the driving plate 404. The telescopic unit 405 includes a telescopic rod fixed between the bottom of the driving plate 404 and the bottom inner wall of the grinding box 1. The surface of the telescopic rod is sleeved with a spring. The upper surface of the driving plate 404 is supported by the rotating roller and will always be in contact with the bottom of the second platform 202. Since the second tower body always keeps horizontal rotation, the guide ball 1 will replace the driving plate 404 to contact the second platform 202. The guide ball 1 forms a rolling support, which greatly reduces the friction caused by the driving plate 404 contacting the second platform 202.

[0028] In order to solve the problem of poor stability of the second platform 202 due to its only support by the driving plate 404 during the up and down sliding process, a plurality of support columns 6 distributed in a ring shape are welded on the bottom inner wall of the grinding box 1, and a support ring 7 is welded between the top ends of the plurality of support columns 6. A plurality of guide balls 2 are evenly installed on the surface of the support ring 7 for uniform rotation. When the second platform 202 moves downward to expand the grinding chamber, the guide balls on the support ring 7 will form a rolling support for the bottom of the descending second platform 202, thereby reducing friction and improving the stability of the second platform 202.

[0029] In order to ensure that the second platform 202 can always maintain horizontal rotation during the up and down movement process, a driving mechanism 2 5 is installed at the upper end of the driving box. The driving mechanism 2 5 includes a motor 2 501 fixed to the upper part of the grinding box 1 by bolts. A rectangular rotating shaft 502 is connected to the output shaft of the motor 2 501. A rectangular mounting groove is opened on the upper part of the second platform 202. The rotating shaft 502 is movably inserted in the rotating shaft 502. When the second platform 202 moves up and down, since the mounting grooves on the rotating shaft 502 and the second platform 202 are both rectangular, the rotating shaft 502 and the second platform 202 are limited to each other, so that the second platform 202 can not only slide relative to the rotating shaft 502, but also the rotating shaft 502 can always drive the second platform 202 to rotate through the motor 2 501.

[0030] In order to solve the problem that the Huangjing material in the grinding box 1 is not easy to discharge after grinding, in this solution, a collecting groove 8 with a ring-shaped cross-section width of 20 cm is opened at the edge of the bottom inner wall of the grinding box 1, the bottom end port of the grinding chamber is located directly above the collecting groove 8, and a discharge port penetrating the outer wall of the grinding box 1 is opened on one side of the collecting groove 8, and a push plate 301 that can rotate around the collecting groove 8 is installed in the collecting groove 8, and the push plate 301 is fixed to the bottom of the second platform 202 through a connecting rod 302. The second platform 202 is driven by rotation during grinding, so that the push plate 301 can be synchronously driven to rotate in the collecting groove 8, so that the materials that fall into the collecting groove 8 can be gathered and finally discharged from the grinding box 1 when passing through the discharge port.

[0031] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0032] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
