Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figure 1-4 As shown, this embodiment provides a grinding apparatus for drug production, including:

[0031] The base 1 has two support plates 2 installed on its upper side, and a material collection mechanism 6 is fixed between the two support plates 2.

[0032] The processing box 4 is located above the collecting mechanism 6. The upper end face of the processing box 4 is provided with a feeding hopper 401 that communicates with its inner cavity. A top cover is placed on the top of the feeding hopper 401. The processing box 4 is provided with a crushing and grinding mechanism 5. Two side plates 402 are symmetrically installed on the side of the processing box 4. The side plates 402 are located on the upper side of the support plate 2. A screw cylinder 403 that is slidably fitted in the support plate 2 is installed on the lower side of the side plates 402.

[0033] A grinding filter plate 8 is clamped between the processing box 4 and the collecting mechanism 6. A sleeve 801 is provided around the periphery of the grinding filter plate 8. The upper and lower parts of the sleeve 801 are respectively sleeved around the periphery of the processing box 4 and the collecting mechanism 6.

[0034] A lifting drive mechanism 7 is used to drive the screw barrel 403 to move up and down, and a rotary drive mechanism 10 is provided on the base 1 to drive the two lifting drive mechanisms 7 to rotate simultaneously.

[0035] One application of this embodiment is as follows: In use, first open the top cover of the feed hopper 401, then feed the drug to be ground into the inner cavity of the processing box 4 from the feed hopper 401, and close the top cover. Then, start the crushing and grinding mechanism 5 on the processing box 4 to crush and grind the drug. The ground drug particles move downwards under gravity onto the grinding filter plate 8, which is clamped between the processing box 4 and the collection mechanism 6. Because the grinding filter plate 8 is provided with a sleeve 801 on its periphery, and the upper and lower parts of the sleeve 801 are respectively fitted around the processing box 4 and the collection mechanism 6, forming a sealed clamping state, only fine powder that meets the particle size requirements can pass through the grinding filter plate 8 into the collection mechanism 6 for collection, and then... The material collection mechanism 6 discharges downwards. When the grinding filter plate 8 needs to be replaced or cleaned, the two lifting drive mechanisms 7 are driven to rotate simultaneously by the rotary drive mechanism 10 on the base 1. The lifting drive mechanism 7 drives the screw barrel 403 to slide upwards. Since the screw barrel 403 is installed on the lower side of the side plate 402, and the side plate 402 is symmetrically installed on the side of the processing box 4, the entire processing box 4 is driven to rise and fall, separating the processing box 4 from the material collection mechanism 6. The grinding filter plate 8 can be removed due to the loss of clamping force. After replacement or cleaning, the lifting drive mechanism 7 drives the processing box 4 to descend in the opposite direction. The sleeve 801 is then re-sleeved around the processing box 4 and the material collection mechanism 6, restoring stable clamping of the grinding filter plate 8. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0036] The rotary drive mechanism 10 and two lifting drive mechanisms 7 work together to drive the two screw cylinders 403 to slide simultaneously, which facilitates the overall lifting and lowering of the processing box 4. This makes it easier to disassemble and clean the grinding filter plate 8 clamped between the processing box 4 and the collection mechanism 6. The grinding filter plate 8 with a suitable aperture can be replaced according to the precision requirements of the medicinal material grinding, and the ease of disassembly and installation of the grinding filter plate 8 is improved. The sleeve 801 is fitted around the processing box 4 and the collection mechanism 6 to facilitate the stable clamping and sealing of the grinding filter plate 8, and also facilitates the positioning and installation of the grinding filter plate 8.

[0037] Specifically, two limiting sliders 404 are installed on the lower side of the screw barrel 403, and two channels are provided on the inner wall side of the support plate 2, with the limiting sliders 404 slidingly engaged in the channels.

[0038] By cooperating with the channel, the sliding distance and direction of the limiting slider 404 are limited, reducing the probability that the screw cylinder 403 will detach from the support plate 2 due to excessive upward movement.

[0039] To achieve the lifting and lowering of the screw barrel 403 by rotating the lifting drive mechanism 7, its specific structure is as follows: Figure 2-4 As shown. The lifting drive mechanism 7 includes an extension rod 702 that is rotatably fitted in the support plate 2. The lower end of the extension rod 702 extends into the base 1 and is equipped with a second bevel gear 701. The upper end of the extension rod 702 is equipped with a screw 704 that is threaded into the screw barrel 403.

[0040] The screw 704 and the screw barrel 403 work together to facilitate the conversion of the rotational motion of the lifting drive mechanism 7 into the linear lifting motion of the screw barrel 403; at the same time, the threaded relationship between the screw 704 and the screw barrel 403 facilitates the self-locking function, reduces the risk of the processing box 4 falling unexpectedly when not in operation, and enhances the safety of the equipment.

[0041] To limit the vertical displacement of the extension rod 702, its specific structure is as follows: Figure 3 As shown. The support plate 2 is fitted with a bearing 703, which is mounted on the upper circumference of the extension rod 702.

[0042] The bearing 703 is installed on the upper periphery of the extension rod 702, which facilitates the smooth rotation of the extension rod 702 within the support plate 2, reduces frictional resistance and wear, and improves the smoothness and durability of the lifting drive mechanism 7, thereby achieving the reliability and long-term stability of the lifting process of the processing box 4.

[0043] To enable the rotary drive mechanism 10 to drive the two second bevel gears 701 to rotate simultaneously, its specific structure is as follows: Figure 1-2As shown. The rotary drive mechanism 10 includes a first motor 1001 mounted on one side of the base 1. The output shaft of the first motor 1001 is equipped with a rotary shaft 1002 that is rotatably engaged in the base 1. The circumference of the rotary shaft 1002 is equipped with a first bevel gear 1003 that meshes with the second bevel gear 701.

[0044] The first motor 1001 drives the rotating shaft 1002 to rotate the two first bevel gears 1003. The first bevel gears 1003 mesh with the second bevel gear 701, which facilitates the simultaneous rotation of the two lifting drive mechanisms 7, improves the synchronicity and coordination of the lifting of the processing box 4, and reduces the risk of equipment deformation or uneven clamping of the grinding filter plate 8 caused by asynchronous lifting.

[0045] To improve the stability of the lifting and lowering process of the processing box 4, its specific structure is as follows: Figure 4 As shown. Guide posts 405 are installed on the lower sides of both ends of the side plate 402, and the guide posts 405 are slidably fitted inside the support plate 2.

[0046] The guide post 405 is slidably fitted inside the support plate 2, which facilitates vertical guidance when the treatment box 4 is raised and lowered, improves the straightness and stability of the raising and lowering, reduces the risk of lateral swaying or tilting, and improves the alignment accuracy between the treatment box 4 and the grinding filter plate 8.

[0047] To achieve the pulverization and grinding of medicinal materials, its specific structure is as follows: Figure 2 As shown. The crushing and grinding mechanism 5 includes a second motor 501 mounted on the upper end face of the processing box 4. The output shaft of the second motor 501 is fixedly fitted with a rotating shaft 502. The rotating shaft 502 extends into the processing box 4. A plurality of crushing blades 503 and a plurality of grinding blades 504 are mounted on the side of the rotating shaft 502. The crushing blades 503 are located above the grinding blades 504. The grinding blades 504 correspond to the grinding filter plate 8.

[0048] The second motor 501 drives the rotating shaft 502 to rotate the pulverizing blade 503 and the grinding blade 504, which facilitates the pulverization and grinding of the drug, improving grinding efficiency and particle uniformity. The grinding blade 504 cooperates with the grinding filter plate 8 to achieve grinding, which facilitates the efficient passage of fine powder through the grinding filter plate 8, improving the output quality and the ability to control the fineness of the drug.

[0049] To achieve the directed discharge of the ground medicine powder, its specific structure is as follows: Figure 1-3As shown. The material collection mechanism 6 includes a positioning ring 601, the upper part of which is located inside the sleeve 801. The lower end face of the positioning ring 601 is provided with a material collection hopper 602, and the bottom of the positioning ring 601 is provided with a discharge pipe 603. Both the positioning ring 601 and the discharge pipe 603 are connected to the material collection hopper 602. Connecting plates 201 are installed on the opposite inner sides of the two support plates 2. The connecting plates 201 are installed on the sides of the positioning ring 601 and the material collection hopper 602, and the sleeve 801 is located above the connecting plates 201.

[0050] The upper part of the positioning ring 601 is located inside the sleeve 801, which facilitates alignment with the processing box 4, so as to achieve accurate positioning and stable clamping of the grinding filter plate 8; the collection hopper 602 and the discharge pipe 603 are connected to facilitate the collection and continuous discharge of the ground medicine, thereby improving the collection efficiency and discharge smoothness; the support plate 2 and the collection mechanism 6 are connected by the connecting plate 201 to achieve stable support for the collection mechanism 6.

[0051] Specifically, sealing rings 9 are installed on the lower end face of the processing box 4 and the upper end face of the positioning ring 601, and the grinding filter plate 8 is located between the upper and lower sealing rings 9.

[0052] By using the sealing ring 9 in conjunction with the grinding filter plate 8, the sealing of the grinding area is enhanced, reducing drug particle leakage or contamination, improving the sealing and hygiene standards of the grinding environment, and reducing material loss.

[0053] To collect the powder discharged from the discharge pipe 603, its specific structure is as follows: Figure 1-2 As shown. The upper center of the base 1 is provided with a positioning frame 101 and a receiving box 3. The receiving box 3 is located below the discharge pipe 603, and the positioning frame 101 is located on the lower periphery of the receiving box 3.

[0054] The receiving box 3 is positioned by the positioning frame 101 set on the base 1, which facilitates the stable placement and quick replacement of the receiving box 3 and improves the convenience of receiving materials.
