Description

Technical Field

[0001] This utility model relates to the field of Polygonatum processing technology, and in particular to a powdering device for Polygonatum. Background Technology

[0002] The rhizome is cylindrical, and due to the swelling of the nodes, the internodes are thicker at one end and thinner at the other, with short branches at the thicker end (in traditional Chinese medicine records, this type of rhizome is used to make the medicinal material called "chicken-head polygonatum"). Polygonatum has a sweet and refreshing taste and is a key ingredient in many traditional Chinese medicine prescriptions, with a long tradition of its use in the Qinling Mountains. Polygonatum can be used to treat symptoms such as spleen and stomach weakness, fatigue, dry mouth and poor appetite, lung deficiency and dry cough, insufficient essence and blood, and internal heat and thirst, as well as to treat tuberculosis and tinea. However, in the field of traditional Chinese medicine, Polygonatum needs to be washed, dried, and finally pulverized into powder for use, thus requiring the use of pulverizing equipment.

[0003] In existing Polygonatum sibiricum powdering technology, grinding rollers are typically used to crush the material by rotating relative to each other. This crushing method has high crushing efficiency and good crushing effect, and can meet the production of Polygonatum sibiricum powder with various fineness requirements. However, in existing technologies, after the Polygonatum sibiricum material is crushed by the grinding rollers, some material residue often adheres to the surface of the grinding rollers. If these residues are not cleaned in time, they will not only reduce the crushing efficiency, but also easily affect the purity and quality of the crushed material. In current technologies, although the crushing effect of the grinding rollers is good, there is generally a lack of effective means to clean the residual material on the surface of the grinding rollers. This not only increases the difficulty of equipment maintenance, but also leads to accelerated wear and tear on the equipment, thereby shortening the service life of the equipment. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a powdering device for Polygonatum sibiricum, which aims to improve the problem that existing powdering devices for Polygonatum sibiricum cannot clean the grinding rollers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a powdering device for Polygonatum sibiricum, comprising a housing, a support frame fixedly connected to the right side of the housing, a motor fixedly connected to the upper part of the support frame, a drive gear fixedly connected to the output end of the motor, a driven gear meshing with the front part of the drive gear, grinding rollers fixedly connected inside both the drive gear and the driven gear, hydraulic cylinders fixedly connected to both outer sides of the housing, movable plates fixedly connected to the output ends of both hydraulic cylinders, and cleaning components fixedly connected to opposite sides of both movable plates, the cleaning components being used to clean the surface of the grinding rollers, a feed hopper fixedly connected to the upper part of the housing, and a discharge hopper fixedly connected to the bottom of the housing.

[0006] Furthermore, a cylinder is fixedly connected to the right side of the box, and a fixed frame is fixedly connected to the output end of the cylinder.

[0007] Furthermore, the cleaning assembly includes connecting rods and scrapers, with one end of each of the connecting rods fixedly connected to opposite sides of the two movable plates, and the other end of each of the connecting rods fixedly connected to opposite sides of the two scrapers.

[0008] Furthermore, both sides of the inner side of the box are fixedly connected to limit frames, and multiple connecting rods are slidably connected inside the limit frames.

[0009] Furthermore, both of the movable plates are slidably connected inside the limiting frame, and grinding rollers are provided on opposite sides of both scrapers.

[0010] Furthermore, each of the two scrapers is fixedly connected to a limiting rod on the side away from each other, and the multiple limiting rods are slidably connected inside the limiting frame.

[0024] 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.

[0025] Reference Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a powdering device for Polygonatum sibiricum, comprising a housing 1, a support frame 2 fixedly connected to the right side of the housing 1, a motor 3 fixedly connected to the upper part of the support frame 2, a drive gear 4 fixedly connected to the output end of the motor 3, a driven gear 5 meshing with the front part of the drive gear 4, grinding rollers 6 fixedly connected inside both the drive gear 4 and the driven gear 5, hydraulic cylinders 7 fixedly connected to both sides of the outer side of the housing 1, movable plates 9 fixedly connected to the output ends of both hydraulic cylinders 7, and cleaning components fixedly connected to opposite sides of both movable plates 9 for cleaning the surface of the grinding rollers 6, and a feed hopper fixedly connected to the upper part of the housing 1. 22. A discharge hopper 20 is fixedly connected to the bottom of the box body 1. The cleaning assembly includes connecting rods 10 and scrapers 11. One end of each connecting rod 10 is fixedly connected to the opposite side of two moving plates 9, and the other end of each connecting rod 10 is fixedly connected to the opposite side of two scrapers 11. Limiting frames 8 are fixedly connected to both sides of the inside of the box body 1. Each connecting rod 10 is slidably connected to the inside of the limiting frames 8. Each moving plate 9 is slidably connected to the inside of the limiting frames 8. Grinding rollers 6 are provided on the opposite side of each scraper 11. Limiting rods 12 are fixedly connected to the opposite side of each scraper 11. Each limiting rod 12 is slidably connected to the inside of the limiting frames 8.

[0026] First, the material is evenly poured into the box 1 through the feed hopper 22. Then, the motor 3 is started, and the output end of the motor 3 drives the drive gear 4 to rotate. The drive gear 4 meshes with the driven gear 5, thereby driving the driven gear 5 to rotate synchronously. As the drive gear 4 and the driven gear 5 rotate, the two grinding rollers 6 rotate relative to each other, performing efficient crushing of the Polygonatum. After the crushing operation is completed, the two hydraulic cylinders 7 are started. The output end of the hydraulic cylinders 7 pushes the moving plate 9 to slide smoothly within the limit frame 8. The limit frame 8 is the moving plate 9 and the scraper. The movement of 11 provides guidance and restraint, ensuring that they move smoothly on the predetermined track. As the moving plate 9 moves, the connecting rod 10 moves accordingly, thereby driving the scraper 11 to move. The movement of the scraper 11 causes the limiting rod 12 to slide synchronously inside the limiting frame 8. The limiting rod 12 moves with the scraper 11. Its function is to assist the movement of the scraper 11 and maintain the correct position of the scraper 11. The two scrapers 11 approach each other and fit tightly against the surface of the grinding roller 6, effectively scraping off the material residue on the roller surface.

[0027] Reference Figure 1 , Figure 4 and Figure 6A cylinder 13 is fixedly connected to the right side of the housing 1. A fixed frame 17 is fixedly connected to the output end of the cylinder 13. A screen frame 18 is set inside the fixed frame 17. Limit seats 14 are fixedly connected to both sides of the inside of the housing 1. Limit blocks 15 are slidably connected inside the two limit seats 14. A fixed frame 17 is fixedly connected to the opposite side of the two limit blocks 15. A locking block 16 is fixedly connected to the upper part of the two limit blocks 15. The two locking blocks 16 are slidably connected inside the limit seats 14. A fixed frame 21 is fixedly connected to the outside of the housing 1. A baffle 19 is rotatably connected to the left side of the housing 1. A guide plate 23 is fixedly connected to the inside of the housing 1. The guide plate 23 is set on the upper part of the screen frame 18.

[0028] The function of the guide plate 23 is to guide the crushed material smoothly into the screen frame 18, ensuring that the material is evenly distributed in the screen frame 18, preparing for the screening operation. The crushed material, guided by the guide plate 23, falls smoothly into the interior of the screen frame 18. Then, the cylinder 13 is activated, and its output end pushes the fixed frame 17 to move precisely. During the movement of the fixed frame 17, the limiting block 15 and the locking block 16 slide synchronously inside the limiting seat 14. The limiting seat 14 provides a sliding track for the limiting block 15 and the locking block 16, ensuring that the screen frame 18 moves smoothly within the box. The movement inside the body 1 is confined to the correct path. Under the interaction of the limit seat 14 and the limit block 15, the fixed frame 17 precisely controls the reciprocating movement of the screen frame 18 inside the box 1. Qualified fine powder material falls downwards as it passes through the screen holes and is discharged to the outside through the discharge hopper 20. Unqualified larger particles and impurities are intercepted by the screen frame 18. After the screening operation is completed, the cylinder 13 is started again to push the fixed frame 17 to the left and open the baffle 19. After the fixed frame 17 is moved out, the screen frame 18 can be easily removed, which facilitates a thorough cleaning of the inside of the screen frame 18.

[0029] Working Principle: First, the material is poured into the box 1 through the feed hopper 22. The motor 3 is started, and the output end of the motor 3 drives the drive gear 4 to rotate. The drive gear 4 drives the meshing driven gear 5 to rotate. When the drive gear 4 and driven gear 5 rotate, they drive the two grinding rollers 6 to rotate relative to each other. The two grinding rollers 6 grind the Polygonatum. After grinding, the two hydraulic cylinders 7 are started. The output ends of the two hydraulic cylinders 7 push the moving plate 9 to slide inside the limit frame 8. When the moving plate 9 moves, it drives the connecting rod 10 to move. When the connecting rod 10 moves, it drives the scraper 11 to move. When the scraper 11 moves, it drives the limit rod 12 to slide inside the limit frame 8. Multiple limit rods 12 move with the scraper 11. The two scrapers 11 approach each other, scraping off the powder on the grinding rollers 6, effectively cleaning the grinding rollers 6 and removing material residue from the roller surface to ensure grinding. The surface of the grinding roller 6 is smooth, which improves the crushing efficiency. Next, the crushed material falls into the inside of the screen frame 18 through the guide plate 23. The cylinder 13 is started, and the output end of the cylinder 13 pushes the fixed frame 17 to move. When the fixed frame 17 moves, it drives the limiting block 15 and the locking block 16 to slide inside the limiting seat 14. Under the action of the limiting seat 14 and the limiting block 15, the fixed frame 17 drives the screen frame 18 to move back and forth inside the box 1 to screen the material. The qualified material falls downward and is discharged outward through the discharge hopper 20. The unqualified material and impurities remain inside the screen frame 18. The cylinder 13 is started to push the fixed frame 17 to move to the left and open the baffle 19. After the fixed frame 17 is removed, the screen frame 18 can be removed to clean the inside. This makes it easy to screen the material, remove powder and impurities that do not meet the fineness requirements, and improve the quality and consistency of the product.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
