Description

Technical Field

[0001] This utility model relates to the field of Dendrobium officinale processing technology, specifically to a Dendrobium officinale ultrafine pulverizer. Background Technology

[0002] Dendrobium officinale, a traditional and precious Chinese medicinal herb, has its stems ground into powder, making its active ingredients more easily absorbed by the human body. It is widely used in health products and traditional Chinese medicine preparations. Grinding is one of the core processes in the processing of Dendrobium officinale; the fineness and uniformity of the powder directly affect the efficacy and quality of the product. Therefore, high precision and efficiency are required for the grinding equipment.

[0003] Most current Dendrobium officinale grinding devices employ a single-stage grinding structure, processing the stems only once through a single grinding gap. Due to the tough texture and high fiber content of Dendrobium officinale stems, single-stage grinding is insufficient to fully break down the fiber structure. Furthermore, the uneven grinding of materials during single-stage grinding easily leads to over-grinding and clumping of some materials, while others remain incompletely ground, severely affecting powder uniformity. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide an ultra-fine pulverizer for Dendrobium officinale, which solves the problem mentioned in the background art that most current Dendrobium officinale grinding devices adopt a single-stage grinding structure, which makes it difficult to fully break the fiber structure, resulting in some materials not being ground thoroughly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrafine pulverizer for Dendrobium officinale, comprising a cylinder, an annular feeding block on the inner wall of the cylinder, a bottom plate at the bottom of the cylinder, a screw threaded through the center of the surface of the bottom plate and connected to the screw threadedly, the top end of the screw being rotatably connected to a support frame, the support frame being fixedly connected to the bottom of a circular plate, and a multi-level, layered grinding cone being rotatably connected to the top end of the circular plate, the grinding cone being located directly below the feeding block.

[0006] In this technical solution, after the medicinal materials are pulverized, they enter the gap between the feed block and the grinding cone. At this time, the grinding cone rotates to grind the medicinal materials. By utilizing the gradient gap formed by the multi-stage layering and the feed block, the material is ground layer by layer. Compared with traditional single-stage grinding, this structure makes it easier to process materials from coarse particles to fine powder, greatly reduces the number of grinding times, significantly improves grinding efficiency and powder uniformity, fully breaks down the fiber structure of Dendrobium, and facilitates the release of effective ingredients.

[0007] Preferably, a No. 3 servo motor is fixedly connected to the center of the bottom of the circular plate, and the tail end of the drive shaft of the No. 3 servo motor is connected to the grinding cone above via a coupling.

[0008] Preferably, the bottom of the support frame on both sides of the screw is fixedly connected with a limiting rod, the bottom end of the limiting rod penetrates the surface of the base plate and is slidably connected to the base plate, and a scale strip is fixedly connected to the bottom of the base plate.

[0009] Preferably, a top frame is fixedly connected to the top of the cylinder, and a servo motor is fixedly connected to the center of the top of the top frame. The tail end of the drive shaft of the servo motor is connected to the top of the drive rod via a coupling, and a spiral blade is fixedly connected to the surface of the drive rod.

[0010] Preferably, two horizontal crushing rollers are rotatably connected between the inner sidewalls of the cylinder. One end of each crushing roller is fixedly connected to a gear, and the two gears mesh with each other. The other end of one crushing roller is connected to the tail end of the drive shaft of the second servo motor, which is fixedly connected to the outer sidewall of the cylinder, via a coupling.

[0011] Preferably, the bottom of the grinding cone is fixedly connected to two storage frames, the bottom of the storage frames is telescopically fitted with a lifting rod, the top of the lifting rod is fixedly connected to the inner wall of the storage frame with a spring, and the bottom of the lifting rod is fixedly connected to a scraper.

[0012] Preferably, a central cylinder is fixedly connected to the top of the bottom plate on the outer side of the support frame, the bottom of the scraper is in contact with the bottom plate, and the left and right ends of the scraper are in contact with the inner wall of the cylinder and the outer wall of the central cylinder, respectively.

[0013] Preferably, the left and right side walls of the base plate are fixedly connected to lower support blocks, the left and right outer side walls of the cylinder are fixedly connected to upper support blocks, and an electric push rod is fixedly connected between the upper support blocks and the lower support blocks.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model incorporates a feeding block and a rotatable grinding cone inside the cylinder. After the medicinal materials are pulverized, they enter the gap between the feeding block and the grinding cone. At this time, the grinding cone rotates to grind the medicinal materials. By utilizing the gradient gap formed by the multi-stage layering and the feeding block, the material is ground layer by layer. Compared with traditional single-stage grinding, this structure makes it easier to process materials from coarse particles to fine powder, significantly reduces the number of grinding times, significantly improves grinding efficiency and powder uniformity, fully breaks down the fiber structure of Dendrobium, and facilitates the release of effective ingredients.

[0015] 2. This utility model, by setting a support frame and a screw below the grinding cone, allows for precise changes in the gap between the grinding cone and the feed block. When the grinding fineness needs to be adjusted, simply rotating the screw will cause the circular plate and the grinding cone to move up and down synchronously through the support frame. This flexibly adapts to different fineness requirements, greatly improves the adaptability of the device to different processing scenarios, and expands the application range of the device.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0019] A Dendrobium officinale ultrafine pulverizer, see [link / reference] Figures 1 to 5 The device includes a cylinder 1, with an annular feeding block 7 on the inner wall of the cylinder 1. A bottom plate 2 is provided at the bottom of the cylinder 1. A screw 12 passes through the center of the surface of the bottom plate 2 and is threadedly connected to the screw 12. The top end of the screw 12 is rotatably connected to a support frame 11. The support frame 11 is fixedly connected to the bottom of a circular plate 9. A multi-level grinding cone 8 is rotatably connected to the top end of the circular plate 9. The grinding cone 8 is located directly below the feeding block 7. A third servo motor 10 is fixedly connected to the center of the bottom of the circular plate 9. The tail end of the drive shaft of the third servo motor 10 is connected to the grinding cone 8 above via a coupling.

[0020] In the above technical solution, the No. 3 servo motor 10 is started, driving the grinding cone 8 at the top of the circular plate 9 to rotate at high speed; Dendrobium officinale material is put into the cylinder 1, and after preliminary crushing, it falls onto the annular feeding block 7, and is evenly dispersed along the feeding block 7, falling into the gap between the grinding cone 8 and the feeding block 7; using the multi-level layered structure of the grinding cone 8, the material passes through different levels of grinding gaps in sequence under the action of the rotating grinding cone 8, realizing progressive fine grinding. Compared with traditional single-stage grinding, this structure makes it easier to process the material from coarse particles to fine powder, greatly reducing the number of grinding times, significantly improving grinding efficiency and powder uniformity, fully breaking the Dendrobium officinale fiber structure, and facilitating the release of effective ingredients.

[0021] Specifically, such as Figure 5 As shown, the bottom of the support frames 11 on both sides of the screw 12 is fixedly connected to limit rods 121. The bottom end of the limit rod 121 penetrates the surface of the base plate 2 and is slidably connected to the base plate 2. The limit rod 121 slides along the base plate 2 with the support frame 11, limiting the rotation direction of the support frame 11 and ensuring that the grinding cone 8 moves only in the vertical direction. The bottom of the base plate 2 is fixedly connected to a scale strip 122, which allows for direct observation of the movement distance of the limit rod 121 and precise control of the grinding gap adjustment. When it is necessary to adjust the grinding fineness, the screw 12 is rotated. Since the screw 12 is threadedly connected to the base plate 2, the rotation of the screw 12 drives the support frame 11 at the top to move up and down. The support frame 11 simultaneously drives the circular plate 9 and the grinding cone 8 to rise and fall, changing the gap between the grinding cone 8 and the feed block 7. This allows for flexible adaptation to different fineness requirements, greatly improving the adaptability of the device to different processing scenarios and expanding the application range of the device.

[0022] Furthermore, such as Figure 3 and Figure 4 As shown, two storage frames 14 are fixedly connected to the bottom of the grinding cone 8. A lifting rod 15 is telescopically sleeved at the bottom of the storage frame 14. A spring 151 is fixedly connected between the top of the lifting rod 15 and the inner wall of the storage frame 14. A scraper 16 is fixedly connected to the bottom of the lifting rod 15. A central cylinder 13 is fixedly connected to the top of the bottom plate 2 on the outer side of the support frame 11. The bottom of the scraper 16 contacts the bottom plate 2, and the left and right ends of the scraper 16 contact the inner wall of the cylinder 1 and the outer wall of the central cylinder 13, respectively. By scraping the surface of the bottom plate 2 with the scraper 16 during the grinding process, it is convenient to collect the ground powder in the future.

[0023] In the above technical solution, the ground powder falls onto the bottom plate 2, and when the grinding cone 8 rotates, it drives the bottom collection frame 14 to rotate synchronously. The collection frame 14 drives the scraper 16 to slide along the surface of the bottom plate 2 through the lifting rod 15. Under the elastic force of the spring 151, the scraper 16 is always in close contact with the bottom plate 2. At the same time, its left and right ends are attached to the inner wall of the cylinder 1 and the outer wall of the central cylinder 13, scraping and concentrating the powder on the bottom plate 2, which facilitates cleaning the bottom plate 2 and improves the powder collection rate. The spring 151 can adaptively extend and retract according to the slight undulations of the bottom plate 2 surface to ensure that the scraper 16 is continuously attached to the bottom plate 2.

[0024] It is worth noting that, such as Figure 1 As shown, lower support blocks 301 are fixedly connected to the left and right side walls of the base plate 2, and upper support blocks 302 are fixedly connected to the left and right outer side walls of the cylinder 1. An electric push rod 3 is fixedly connected between the upper support block 302 and the lower support block 301. When it is necessary to repair the internal parts of the cylinder 1 or collect the ground material, the electric push rod 3 is activated. The piston rod of the electric push rod 3 drives the upper support block 302 to move upward, and the upper support block 302 simultaneously drives the cylinder 1 to rise vertically, increasing the space between the cylinder 1 and the base plate 2. After the repair or maintenance is completed, the piston rod of the electric push rod 3 is controlled to retract, driving the cylinder 1 to descend and reset, restoring the normal processing state of the device. It should be noted that the two electric push rods 3 are controlled by the same controller, thus ensuring simultaneous lifting and lowering.

[0025] It is worth noting that, such as Figure 1 and Figure 2 As shown, two horizontal crushing rollers 6 are rotatably connected between the inner walls of the cylinder 1. A gear 601 is fixedly connected to one end of each crushing roller 6, and the two gears 601 mesh with each other. The other end of one crushing roller 6 is connected to the tail end of the drive shaft of a second servo motor 602 fixedly connected to the outer wall of the cylinder 1 via a coupling. The gear 601 transmission ensures that the two crushing rollers 6 rotate synchronously in opposite directions, guaranteeing a stable crushing process and preventing stems from getting stuck between the rollers. The initial crushing process breaks large stems into small particles, reducing the processing load on the subsequent grinding cone 8 and improving overall grinding efficiency.

[0026] It is worth noting that, such as Figure 1 and Figure 3 As shown, a top frame 4 is fixedly connected to the top of the cylinder 1. A servo motor 5 is fixedly connected to the center of the top of the top of the top frame 4. The tail end of the drive shaft of the servo motor 5 is connected to the top of the drive rod 501 via a coupling. A spiral blade 502 is fixedly connected to the surface of the drive rod 501. The spiral structure generates a downward thrust on the material, which is uniformly conveyed to the crushing roller 6 area below, while avoiding the accumulation and blockage of material at the top of the cylinder 1.

[0027] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
