Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material processing equipment, specifically to a multi-stage high-efficiency medicine refining machine. Background Technology

[0002] In the processing of pills, the medicine first needs to be refined using a refining machine. This machine processes the wet-mixed Chinese medicinal materials or excipients, refining the different components into a soft material with a uniform texture, consistent hardness, and density. The refining machine is an auxiliary device to the pill-making machine, serving as a pre-processing unit in the pill-making production line. It mixes, refines, kneads, and extrudes materials into a soft, uniform paste with appropriate hardness. It is particularly effective for processing difficult-to-uniform medicinal materials, such as liquid-powder mixtures or high-hardness, high-viscosity materials (concentrated pastes and dry powders, or honey and dry powders), achieving uniform refining with high production efficiency. It is an indispensable piece of equipment in the pharmaceutical, food, and chemical industries. Especially for Tibetan medicines with poor viscosity, refining can improve the drug's viscosity, making the medicine easier to form into pills. Existing pharmaceutical refining machines work by placing pre-mixed medicinal materials into a feed pan, which then gradually enters a hopper. Under the pressure of a pressure plate, the materials are propelled forward by a screw propeller, extruding them into multiple strips to complete the refining process. However, directly feeding the materials into the screw propeller is difficult because the materials are already in a preliminary mixed state and form clumps. These clumps are prone to clumping during transfer, and directly feeding them into the refining stage would affect the quality of the pills. Furthermore, combinations of different medicinal materials may require multiple refining stages to achieve the pill-forming state, and the number of repetitions needs to be flexibly adjusted according to the state of the clumps. A common practice is to re-feed the extruded clumps into the screw propeller through the feed inlet, during which the clumps come into contact with the outside environment again. This repeated refining increases the possibility of contamination and requires repeated manual transport, resulting in low refining efficiency. Therefore, a multi-stage high-efficiency pharmaceutical refining machine is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a multi-stage high-efficiency pharmaceutical refining machine that is easy to feed and allows for selection of the number of refining cycles based on the actual refining conditions of the pharmaceutical pellet, thereby achieving automated refining and reducing the probability of contamination of the pharmaceutical pellet.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0017] Reference Figures 1 to 3This embodiment provides a multi-stage high-efficiency pharmaceutical refining machine, including a feeding chamber 1, a primary refining chamber 2, and a secondary refining chamber 3. The feeding chamber 1 has a discharge port at its bottom, which communicates with the primary refining chamber 2. The primary refining chamber 2 has a primary refining outlet, which communicates with the secondary refining chamber 3. The feeding chamber 1 is equipped with a compression mechanism for dispersing agglomerated pharmaceutical lumps. The primary refining chamber 2 is equipped with a first spiral propeller 4, and the secondary refining chamber 3 is equipped with a second spiral propeller 5. The primary refining outlet is located at the tail end of the first spiral propeller 4, and the tail end of the second spiral propeller 5 is equipped with a secondary refining outlet 7. A transfer platform 11 is located directly below the secondary refining outlet 7, and a first conveyor belt 12 is mounted on the transfer platform 11, which can move in both forward and reverse directions. The secondary refining chamber 3 is also equipped with a second feed inlet 6. A second conveyor belt 10 is provided between the second feed inlet 6 and the first conveyor belt 12, and the second conveyor belt 10 is used to connect the first conveyor belt 12 and the second feed inlet 6. A third conveyor belt 13 and a receiving box 9 are also provided. One end of the third conveyor belt 13 is connected to the end of the first conveyor belt 12 away from the second conveyor belt 10, and the other end of the third conveyor belt 13 is connected to the receiving box 9. The transfer platform 11 is equipped with a dust cover 8, and the dust cover 8 has a visualization window. That is to say, when the pre-mixed clump of medicine is added into the feed chamber 1, the extrusion mechanism in the feed chamber 1 will pre-extract the clump of medicine by extrusion, so that the clump of medicine is dispersed. The dispersed medicinal materials enter the primary refining chamber 2 for the first stage of refining, and then enter the secondary refining chamber 3 for the second stage of refining. The refined medicinal slurry is extruded through the secondary refining outlet 7. The operator can observe the mixing of the extruded medicinal slurry and adjust the movement direction of the first conveyor belt 12. If the medicinal slurry needs to be refined, the first conveyor belt 12 is controlled to move towards the second conveyor belt 10, and the medicinal slurry is sent back to the second feed inlet 6 to enter the secondary refining chamber 3 for the third stage of refining, and so on until the medicinal slurry reaches the standard. Then, the first conveyor belt 12 is controlled to move towards the third conveyor belt 13, and the extruded medicinal slurry is sent to the receiving box 9.

[0018] The second conveyor belt 10 and the third conveyor belt 13 are respectively equipped with a second dust cover 8 and a third dust cover 8. Setting up multiple dust covers 8 can ensure that the slurry is not contaminated during the refining process or during the feeding process.

[0019] The first conveyor belt 12 is connected to a motor, and the motor realizes the forward and reverse movement of the first conveyor belt 12 by rotating forward and reverse.

[0020] The first-stage refining chamber is equipped with a first motor, the output end of which is connected to the first spiral propeller 4 to drive the first spiral propeller 4 to rotate; the second-stage refining chamber is equipped with a second motor, the output end of which is connected to the second spiral propeller 5 to drive the second spiral propeller 5 to rotate.

[0021] The extrusion mechanism includes a first extrusion cylinder 101 and a second extrusion cylinder 102, which are symmetrically arranged along the vertical central axis of the extrusion chamber. The first extrusion cylinder 101 contains a first rotating shaft that passes through the extrusion chamber and connects to the output end of a third motor 107 located outside the extrusion chamber. The second extrusion cylinder 102 contains a second rotating shaft parallel to the first rotating shaft. The first rotating shaft has a driving gear 105, and the second rotating shaft has a driven gear 106, which meshes with the driving gear 105. Through the engagement of the driving gear 105 and the driven gear 106, the first extrusion cylinder 101 and the second extrusion cylinder 102 can rotate simultaneously in opposite directions: the first extrusion cylinder 101 rotates towards the second extrusion cylinder 102, and the second extrusion cylinder 102 rotates towards the first extrusion cylinder 101.

[0022] The first extrusion cylinder 101 has first extrusion teeth 103 on its outer periphery, and the second extrusion cylinder 102 has second extrusion teeth 104 on its outer periphery. The first extrusion teeth 103 and the second extrusion teeth 104 mesh with each other. The first extrusion teeth 103 are arranged in a row along the length of the first extrusion cylinder 101, and multiple rows of first extrusion teeth 103 are arranged on the outer periphery of the first extrusion cylinder 101. Similarly, the second extrusion cylinder 102 also adopts a similar arrangement of second extrusion teeth 104, so that when the first extrusion cylinder 101 and the second extrusion cylinder 102 rotate, the first extrusion teeth 103 and the second extrusion teeth 104 mesh precisely at the point where the two extrusion cylinders are close together, thereby achieving the dispersion of the drug clump.

[0023] The top of the feeding chamber 1 is provided with a feeding port for easy feeding.

[0024] This invention provides a multi-stage high-efficiency pharmaceutical refining machine. A transfer platform is located directly below the secondary refining outlet. The first conveyor belt on this platform has an adjustable direction, allowing for flexible selection of whether the extruded pharmaceutical slurry is further refined or sent to a receiving box. The number of refining cycles can also be flexibly selected, making operation more flexible. Furthermore, the entire refining process eliminates the need for manual transfer of the pharmaceutical slurry, reducing contact with the slurry and preventing contamination.
