Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine grinding technology, and in particular to a powder preparation device. Background Technology

[0002] In many fields such as traditional Chinese medicine preparation, food processing, and chemical raw material handling, it is often necessary to grind lumpy or granular materials into powder for subsequent processing, use, or storage. Traditional grinding methods mostly involve manual grinding using mortars and pestles. This method is not only inefficient and labor-intensive, but also produces powders with uneven particle size, making it difficult to meet the requirements of large-scale production and high quality.

[0003] With the development of technology, some mechanical grinding equipment has emerged, but most of these devices have some problems. For example, some grinding equipment uses a single grinding method, only achieving simple rotational grinding of materials, and cannot subject the materials to grinding forces in multiple directions, resulting in insufficient grinding and poor grinding effect. In addition, in terms of equipment maintenance and repair, some grinding equipment has a complex protective structure, making disassembly difficult. When key components such as gears and racks inside the equipment malfunction, timely and convenient repairs are not possible, increasing equipment maintenance costs and downtime, and affecting the continuity and stability of production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing grinding equipment, which suffers from a single grinding method, only achieving simple rotational grinding of materials without subjecting them to grinding forces in multiple directions, resulting in insufficient grinding and poor grinding effect. Furthermore, in terms of equipment maintenance and repair, some grinding equipment has complex protective structures that are difficult to disassemble. When key components such as gears and racks inside the equipment malfunction, timely and convenient repairs are not possible, increasing equipment maintenance costs and downtime, and affecting the continuity and stability of production. Therefore, this invention proposes a powder preparation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A powder preparation apparatus includes a frame, a plurality of grinding grooves are provided on the top of the frame, a discharge hole is provided at the bottom of each grinding groove, a side hole is provided on one side of the frame, and two sets of sealing components for sealing the discharge hole are provided inside the side hole. The set of sealing components near the inner side of the side hole is fixedly set, and the set of sealing components near the outer side of the side hole is slidably set.

[0007] Fixed plates are fixedly installed on both sides of the top of the frame;

[0008] A grinding assembly is disposed between the two fixed plates. The grinding assembly includes a connecting shaft that passes through the fixed plates. Multiple grinding blocks are fixedly sleeved on the outer wall of the connecting shaft. Operating blocks are rotatably connected to both ends of the connecting shaft.

[0009] The top two sides of the frame are provided with strip-shaped grooves, the bottom inner wall of the strip-shaped grooves is fixedly installed with a rack, and the outer wall of the connecting shaft is fixedly sleeved with a gear, which meshes with the rack.

[0010] During operation, pulling the operating block causes the connecting shaft to move laterally, and the gear rotates on the rack, causing the grinding block to rotate and move at the same time, thereby grinding the material.

[0011] In one possible design, the sealing assembly includes multiple strip-shaped limiting boxes, which are fixedly connected to each other by multiple connecting rods. The inner strip-shaped limiting boxes are fixedly installed on the top inner wall of the side hole, and the outer strip-shaped limiting boxes are slidably connected to the top inner wall of the side hole. A tension spring is provided between one side of one of the outer strip-shaped limiting boxes and one side inner wall of the side hole. An arc-shaped groove is formed on the top side of the strip-shaped limiting box, which is located directly below the discharge hole and communicates with the discharge hole.

[0012] In one possible design, a U-shaped limiting block is also included, which is slidably connected to the top inner wall of the side hole to limit the two middle strip-shaped limiting boxes. The U-shaped limiting block is offset from the connecting rod.

[0013] In one possible design, the fixed plate has a clearance hole inside, the connecting shaft passes through the clearance hole, and the connecting shaft is movable within the clearance hole.

[0014] In one possible design, a protective box is also included, which is placed on one side of the fixing plate. The protective box has a threaded groove on one side, and the fixing plate has a threaded hole inside. The threaded hole and the threaded groove are connected by mounting screws.

[0015] In one possible design, a protective side plate is also included, which is rotatably fitted onto the outer wall of the connecting shaft. The bottom of the protective side plate abuts against the top of the frame. When the connecting shaft moves laterally, it drives the protective side plate to move to block the sides of the fixing plate and the protective box.

[0016] In one possible design, a collection box is also included, placed at the bottom of the frame, for collecting powder discharged from the discharge port, and a handle is fixedly installed on one side of the collection box.

[0017] In this application, when in use, the Chinese medicine to be ground is placed inside the grinding tank. At this time, two operating blocks can be pulled by hand to move laterally. The operating blocks drive the connecting shaft to move laterally, and the connecting shaft drives multiple grinding blocks to move laterally. The connecting shaft always moves inside the clearance hole, and the connecting shaft drives the gear to move laterally. The gear rotates continuously on the surface of the rack, which in turn drives the grinding blocks to rotate and move at the same time, thereby realizing the grinding operation of the Chinese medicine and obtaining powder.

[0018] After the powder is ground, the U-shaped limiting block can be pulled horizontally. At this time, the U-shaped limiting block will detach from the two middle strip limiting boxes, and then the outer strip limiting boxes will be pulled by the tension spring. The two strip limiting boxes in the same position will move away from each other, so that the discharge hole can be exposed. The two arc grooves are misaligned, which can facilitate the discharge of the powder inside, which can be collected by the collection box below.

[0019] When the connecting shaft moves laterally, it will drive the two protective side plates to move laterally, thereby appropriately sealing the sides of the fixing plate and the protective box. When maintenance is required, the protective side plates can be moved to both sides to expose the mounting screws. At this time, the mounting screws can be unscrewed from the inside of the threaded hole and threaded groove, thereby releasing the braking state of the protective box. The protective box can be moved up to allow for maintenance of the gears and racks.

[0020] Beneficial effects: By pulling the operating block, the connecting shaft moves laterally, and the gear on the connecting shaft rotates on the rack surface, which in turn drives the grinding block to rotate and move at the same time. This unique grinding method can achieve thorough grinding of Chinese medicine, effectively improve grinding efficiency, and make Chinese medicine be ground into powder faster, meeting the needs of rapid powder preparation.

[0021] Two sets of sealing components are set up. By pulling the U-shaped limiting block laterally, the two sets of strip limiting boxes are moved away from each other under the action of the tension spring, thus exposing the discharge hole. The two arc-shaped grooves are misaligned to facilitate the smooth discharge of internal powder, which is then collected by the collection box below. The operation is simple and convenient, improving the discharge efficiency and reducing powder residue.

[0022] The connecting shaft drives the protective side plate to move laterally, appropriately sealing the sides of the fixed plate and protective box to prevent powder from splashing out or debris from entering and affecting the grinding effect during the grinding process. Simultaneously, when maintenance is required, the protective side plate can be moved to the sides to expose the mounting screws. Unscrewing the mounting screws releases the braking effect on the protective box, allowing the protective box to be moved upwards for inspection of the gears and rack, facilitating equipment maintenance and extending its service life.

[0023] The overall device has a compact structure and a reasonable layout of components. The grinding tank, discharge hole, sealing components, and grinding components work together to form a complete powder preparation system, which not only ensures the smooth realization of grinding and discharge functions, but also makes the overall structure of the equipment stable and easy to operate.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In one embodiment: Refer to Figure 1-5 The specific implementation method of this preparation device is as follows:

[0032] The frame 1 serves as the main support for the entire device. Multiple grinding grooves 10 are evenly spaced on its top, used to hold materials such as traditional Chinese medicine to be ground. Each grinding groove 10 has a discharge hole 11 on its bottom inner wall for discharging powder after grinding. A side hole 6 is provided on one side of the frame 1, and two sets of sealing assemblies are installed inside the side hole 6. In the sealing assembly, multiple outer strip-shaped limiting boxes 14 are slidably connected to the top inner wall of the side hole 6. A first slider is fixedly installed on the top of the outer strip-shaped limiting box 14. Multiple corresponding first sliding grooves are provided on the top inner wall of the side hole 6, and the first sliders are slidably connected inside the first sliding grooves. The multiple strip-shaped limiting boxes 14 are fixedly connected by multiple connecting rods 12 to ensure the relative position stability between the strip-shaped limiting boxes 14. Multiple inner strip-shaped limiting boxes 14 are fixedly installed on the top inner wall of the side hole 6. A tension spring 15 is provided between one side of one of the outer strip-shaped limiting boxes 14 and one side inner wall of the side hole 6. When the tension spring 15 is in a stretched state, the outer strip-shaped limiting box 14 moves laterally to block the discharge hole 11. An arc-shaped groove 16 is opened on one side of the top of the strip-shaped limiting box 14. A U-shaped limiting block 13 is slidably connected to the top inner wall of the side hole 6. A second slider is fixedly installed on the top of the U-shaped limiting block 13. A corresponding second sliding groove is opened on the top inner wall of the side hole 6. The second slider is slidably connected inside the second sliding groove. The U-shaped limiting block 13 is offset from the connecting rod 12. The U-shaped limiting block 13 is used to limit the two middle strip-shaped limiting boxes 14 to prevent them from moving due to the action of the tension spring 15 during normal grinding.

[0033] The top of the frame 1 has two strip-shaped grooves 9 on both sides, and a fixing plate 5 is fixedly installed on each side. The fixing plate 5 is located on one side of the strip-shaped groove 9. A grinding assembly is set between the two fixing plates 5. The fixing plate 5 of the grinding assembly has a clearance hole 22 inside, and the same connecting shaft 3 passes through the two clearance holes 22. The connecting shaft 3 can move within the clearance holes 22. Multiple grinding blocks 4 are fixedly fitted on the outer wall of the connecting shaft 3. The shape and size of the grinding blocks 4 are designed according to the actual grinding requirements to ensure that the material can be fully ground. The two ends of the connecting shaft 3 are rotatably connected to the operating block 17. The operator can move the connecting shaft 3 by pulling the operating block 17. A gear 23 is also fixedly fitted on the outer wall of the connecting shaft 3. A rack 24 is fixedly installed on the bottom inner wall of the strip-shaped groove 9. The gear 23 meshes with the rack 24. When the connecting shaft 3 moves laterally, the gear 23 rotates on the surface of the rack 24, thereby driving the grinding blocks 4 to rotate and move at the same time, so as to grind the material.

[0034] A collection box 7 is placed at the bottom of the frame 1. The collection box 7 is used to collect the powder discharged from the discharge hole 11. A handle 8 is fixedly installed on one side of the collection box 7 to facilitate the operator to move the collection box 7.

[0035] In actual use, the Chinese medicine to be ground is placed inside the grinding tank 10. The operator manually pulls the two operating blocks 17 to move them laterally, or a linear drive mechanism, such as an electric cylinder, is used to move the blocks 17 laterally. The operating blocks 17 drive the connecting shaft 3 to move laterally, and the connecting shaft 3 drives multiple grinding blocks 4 to move laterally. At the same time, the connecting shaft 3 drives the gear 23 to move laterally. The gear 23 rotates continuously on the surface of the rack 24, thereby driving the grinding blocks 4 to rotate and move at the same time, thoroughly grinding the Chinese medicine to obtain a uniform powder. After the powder is ground, the U-shaped limiting block 13 is pulled outward, so that it is detached from the two strip-shaped limiting boxes 14 in the middle. At this time, the outer strip-shaped limiting boxes 14 are pulled by the tension spring 15, and the two strip-shaped limiting boxes 14 in the same position move away from each other, allowing the discharge hole 11 to leak out. The two arc-shaped grooves 16 are also misaligned to facilitate the smooth discharge of the powder inside, which is then collected by the collection box 7 below. When equipment maintenance is required, the protective side plate 18 is moved to both sides to expose the mounting screws 20. The mounting screws 20 are then unscrewed from the threaded holes 19 and threaded grooves 21 to release the braking state of the protective box 2. The protective box 2 is then moved upwards to allow maintenance of the gear 23 and rack 24. This device, through its unique structural design, achieves efficient grinding, convenient material discharge, and easy maintenance, meeting the requirements of large-scale production and high quality.

[0036] This application can be used in the field of grinding traditional Chinese medicine, or in other fields applicable to this application.

[0037] In another embodiment: Reference Figure 1-5 A powder preparation device is disclosed for use in the field of traditional Chinese medicine grinding. The device includes a protective box 2, which is placed on one side of a fixed plate 5. Two symmetrically arranged threaded grooves 21 are formed on one side of the protective box 2. Two symmetrically arranged threaded holes 19 are formed inside the fixed plate 5. The threaded holes 19 and the threaded grooves 21 are connected by the same mounting screw 20, which secures the protective box 2 to the fixed plate 5, thus protecting the internal gears 23 and racks 24. Two symmetrically arranged protective side plates 18 are rotatably fitted onto the outer wall of the connecting shaft 3. The bottom of the protective side plates 18 abuts against the top of the frame 1. When the connecting shaft 3 moves laterally, it causes the two protective side plates 18 to move laterally as well, appropriately sealing the sides of the fixed plate 5 and the protective box 2 to prevent powder from splashing out during the grinding process.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
