Description

Technical Field

[0001] This utility model relates to the field of Dendrobium powder processing technology, and in particular to a low-temperature sealed grinding machine for Dendrobium powder processing. Background Technology

[0002] In the current dendrobium powder processing field, traditional grinding equipment has significant shortcomings: manual feeding easily introduces impurities such as sand and soil, requiring additional manual sorting, increasing costs and posing a high risk of contamination; the powder particles after grinding are uneven in size, lacking a precise sieving mechanism, resulting in a low yield of qualified products; and the absence of a coarse material recycling system means that coarse powder is either directly discarded or requires manual refeeding, leading to raw material waste and efficiency loss. To solve these problems and meet the market demand for high-quality, high-purity dendrobium powder, a low-temperature sealed grinding machine for dendrobium powder has emerged.

[0003] The prior art patent publication number CN209222322U discloses a grinding device for processing Dendrobium officinale, including a grinding machine body. The grinding machine body has an internal crushing mechanism, and a partition plate is welded to the lower part of the grinding machine body near the crushing mechanism. A screening mechanism is also located inside the grinding machine body near the lower part of the partition plate, and a weighing mechanism is located on the inner bottom of the grinding machine body. The weighing mechanism facilitates the weighing of the ground Dendrobium officinale powder, improving the efficiency of Dendrobium officinale production and processing, and making the grinding machine body more functional. The crushing mechanism can crush the Dendrobium officinale before grinding, achieving better grinding results. The screening mechanism can screen the ground Dendrobium officinale, separating unground particles for secondary grinding, reducing labor costs and improving production efficiency.

[0004] Existing technologies improve the grinding effect of Dendrobium through the inclusion of crushing and screening mechanisms. However, in practical use, these grinding devices lack measures for screening sand and soil from the Dendrobium, as well as for the rapid recovery of the screened coarse Dendrobium material. This necessitates manual assistance during operation, reducing processing efficiency and increasing production costs. To address this, we propose a low-temperature sealed grinding machine for Dendrobium powder processing. This solves the problems of inconvenient impurity screening and coarse material handling in existing grinding devices, improving the cleanliness and efficiency of Dendrobium processing while simultaneously reducing labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a low-temperature sealed grinding machine for processing Dendrobium powder, which solves the problems of inconvenient impurity screening and coarse material processing in existing grinding devices mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature sealed grinding machine for processing Dendrobium powder, comprising a feeding hopper, a feeding mechanism at the bottom of the feeding hopper, a processing box connected to the bottom of the feeding hopper, a first screening mechanism movably installed at the upper end of the processing box, an impurity guide plate fixedly installed at the bottom of the first screening mechanism, an impurity discharge port fixedly installed at one end of the impurity guide plate, a grinding machine fixedly installed inside the processing box, the feeding port of the grinding machine being located below the discharge end of the first screening mechanism, a second screening mechanism being provided at the bottom of the grinding machine, and a coarse material guide plate being provided below the discharge end of the second screening mechanism.

[0007] The feed hopper is hinged to a cover at the top. The feeding mechanism includes a drive motor, which is fixedly installed at the top of the processing box. A feeding shaft is rotatably installed at the lower end of the feed hopper. Feeding plates are fixedly welded to the outside of the feeding shaft. There are no fewer than six feeding plates. The six feeding plates are evenly distributed in an array on the outer surface of the feeding shaft with the axis of the feeding shaft as the base point.

[0008] The first screening mechanism includes a first screening screen, one end of which is elastically connected to the inner wall of the processing box near the impurity discharge outlet, and the other end of which is hinged to the inner wall of the processing box via a hanger and a pin. A first vibrator is fixedly installed on the bottom side of the first screening screen near the impurity discharge outlet, and the angle between the first screening screen and the inner wall of the processing box is not less than 60 degrees.

[0009] The second screening mechanism includes a second screening screen. The end of the second screening screen away from the coarse material guide plate is elastically connected to the inner wall of the processing box, and a second vibrator is fixedly installed on its bottom side. The end of the second screening screen near the coarse material guide plate is hinged to the inside of the processing box.

[0010] The processing box is equipped with a coarse material circulation mechanism, which includes a circulation cylinder. An auger is rotatably installed inside the circulation cylinder.

[0012] This utility model discloses a low-temperature sealed grinding machine for processing Dendrobium officinale powder. It employs a feeding mechanism inside the hopper, with a first screening mechanism installed below it. The feeding mechanism controls the feeding speed of the Dendrobium officinale raw material. Combined with the vibrating screening action of the first screening screen, impurities such as sand and soil in the raw material are screened out and guided to the impurity discharge outlet by an impurity guide plate. This improves the cleanliness of the Dendrobium officinale before grinding, thus enhancing the quality of the Dendrobium officinale powder. A circulation cylinder connected to one end of the coarse material guide plate, with a rotatable auger inside, allows the coarse material produced after screening by the second screening mechanism to be fed back into the grinding machine for secondary grinding. This structure eliminates the inconvenience of manual material receiving and feeding, reduces the risk of environmental pollution of the Dendrobium officinale powder, alleviates the burden of manual labor, and improves processing efficiency and quality.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a low-temperature sealed grinding machine for processing Dendrobium officinale powder, including a feeding hopper 1, a feeding mechanism 2 provided at the bottom of the feeding hopper 1, a cover 14 hinged to the top of the feeding hopper 1, the feeding mechanism 2 including a drive motor 15, the drive motor 15 fixedly installed at the top of the processing box 3, a feeding shaft 16 rotatably installed at the lower end of the inside of the feeding hopper 1, feeding plates 17 fixedly welded to the outside of the feeding shaft 16, and at least six feeding plates 17, which are evenly distributed in an array on the outer surface of the feeding shaft 16 with the axis of the feeding shaft 16 as the base point. The bottom end of the feeding hopper 1 is connected to the processing box 3, and the upper end of the processing box 3 is movably mounted... The system is equipped with a first screening mechanism 4, with an impurity guide plate 5 fixedly installed at the bottom of the first screening mechanism 4. An impurity discharge port 6 is fixedly installed at one end of the impurity guide plate 5. The first screening mechanism 4 includes a first screening screen 18. One end of the first screening screen 18 near the impurity discharge port 6 is elastically connected to the inner wall of the processing box 3, and the other end is hinged to the inner wall of the processing box 3 through a hanging rod 19 and a pin 20. A first vibrator 21 is fixedly installed on the bottom side of the end of the first screening screen 18 near the impurity discharge port 6. The included angle between the first screening screen 18 and the inner wall of the processing box 3 is not less than 60 degrees. A baffle plate 26 is slidably embedded inside the impurity discharge port 6. A handle 27 is fixedly installed on the top surface of the cover 14.

[0021] During operation, the cap 14 closes to achieve a seal, and the Dendrobium officinale raw material is fed into the feed hopper 1. The drive motor 15 drives the feeding shaft 16 to rotate, and the feeding plate 17 evenly feeds the raw material into the processing box 3. The Dendrobium officinale raw material falls onto the first screening screen 18, and the first vibrator 21 vibrates, causing the screen to tilt and vibrate. Sand and soil fall through the screen holes to the impurity guide plate 5 and are discharged through the impurity discharge outlet 6. The baffle plate 26 can control the discharge. This structure allows the Dendrobium officinale raw material to be cleaned before entering the grinder 7, improving the cleanliness of the Dendrobium officinale raw material and thus improving the quality of Dendrobium officinale powder production.

[0022] A grinder 7 is fixedly installed inside the processing box 3. The feed inlet of the grinder 7 is located below the discharge end of the first screening mechanism 4. A second screening mechanism 8 is set at the bottom of the grinder 7. A coarse material guide plate 9 is set below the discharge end of the second screening mechanism 8. The second screening mechanism 8 includes a second screening screen 22. The end of the second screening screen 22 away from the coarse material guide plate 9 is elastically connected to the inner wall of the processing box 3, and a second vibrator 23 is fixedly installed on its bottom side. The end of the second screening screen 22 near the coarse material guide plate 9 is hinged to the inside of the processing box 3.

[0023] The raw materials screened by the first screening mechanism 4 fall into the feed inlet of the grinding mill 7 below for grinding. The ground material enters the second screening mechanism 8, where the second vibrator 23 drives the second screening screen 22 to vibrate. Fine powder is discharged and collected through the screen holes, while coarse material that does not meet the standards slides along the screen surface to the coarse material guide plate 9.

[0024] A coarse material circulation mechanism 10 is fixedly installed on one side of the processing box 3. The coarse material circulation mechanism 10 includes a circulation cylinder 11. An auger 12 is rotatably installed inside the circulation cylinder 11. The bottom inlet of the circulation cylinder 11 is connected to the coarse material guide plate 9. The top outlet is located above the inlet of the grinding mill 7. A servo motor 13 is fixedly installed at the bottom inside the circulation cylinder 11. The output end of the servo motor 13 is fixedly connected to the shaft end of the auger 12 through a coupling. A powder discharge port 24 is fixedly installed at the bottom of the processing box 3. A solenoid valve 25 is fixedly installed on the outside of the powder discharge port 24. A PLC controller 28 is fixedly installed on the outer wall of the processing box 3. The PLC controller 28 controls the start and stop and speed of the servo motor 13 and the drive motor 15. The PLC controller 28 controls the start and stop of the first vibrator 21, the second vibrator 23, and the solenoid valve 25.

[0025] The coarse material is connected to the feed inlet on the bottom side of the circulation cylinder 11 via the coarse material guide plate 9. In the coarse material circulation mechanism 10, the servo motor 13 drives the auger 12 to lift the coarse material and feed it back into the feed inlet of the grinder 7 for secondary grinding. This eliminates the inconvenience of manual material handling and feeding, and improves the airtightness and production efficiency of the Dendrobium powder production process.

[0026] Working principle: First, open the cover 14 and pour the Dendrobium into the feed hopper 1. Then close the cover 14 and turn on the first vibrator 21, the second vibrator 23, the grinder 7 and the servo motor 13 through the PLC controller 28 to put the grinding equipment into the working preparation state. Then turn on the drive motor 15, which drives the feeding shaft 16 to rotate, thereby driving the multiple arrayed feeding plates 17 to rotate synchronously, so that the Dendrobium raw material can be evenly fed. The Dendrobium first falls onto the first screening screen 18. The first vibrator 21 drives the first screening screen 18 to vibrate, which can screen out impurities such as sand and soil in the Dendrobium. The screened impurities fall onto the impurity guide plate 5 and are discharged from the impurity outlet 6. The Dendrobium after impurity removal rolls down along the first screening screen 18 into the grinder 7. The ground Dendrobium powder falls through the outlet of the grinder 7 onto the second screening screen 22 to achieve coarse material sorting. Dendrobium powder that meets the particle size requirements falls into the powder discharge outlet 24 and is discharged. The coarse material that has been screened falls along the second screening screen 22 into the coarse material guide plate 9 and enters the circulation cylinder 11 along the coarse material guide plate 9. Through the spiral feeding action of the auger 12, the Dendrobium coarse material is sent back into the grinder 7 for secondary grinding. This cycle is repeated until all the Dendrobium raw materials are ground into powder that meets the requirements.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
