Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical lozenge production equipment, and in particular to a pharmaceutical lozenge production apparatus. Background Technology

[0002] In the production of Dai medicine lozenges, the raw materials are mostly plant powders or granular mixtures. Because some Dai medicinal materials (such as *Ligustrum lucidum* leaves and *Symplocos edulis*) contain viscous components, clumping and accumulation are prone to occur during the feeding stage. This leads to uneven distribution of the raw materials when they enter the tableting stage, resulting in significant differences in lozenge weight and unstable content of active ingredients. Existing rotary tablet presses do not have a dedicated stirring mechanism designed for the characteristics of Dai medicinal raw materials, making it difficult to solve the problem of clumping of viscous materials. Therefore, a pharmaceutical lozenge production device is proposed to address these issues. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a pharmaceutical tablet production device, which aims to improve the problem in the prior art that "existing rotary tablet presses lack a special stirring mechanism for the viscous raw materials of Dai medicine, resulting in the raw materials being prone to clumping and piling up during the feeding stage".

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pharmaceutical lozenge production device, comprising a machine body, wherein a stirring mechanism is provided on the outer side of the upper part of the feeding hopper of the machine body, the stirring mechanism including a mounting base fixedly connected to the outer side of the feeding hopper of the machine body by fixing bolts, a mounting cover rotatably connected to the left side of the mounting base, a motor being fixedly connected through the upper part of the mounting cover, a support member being fixedly connected to the inner wall of the mounting base, a stirring rod being rotatably connected through the middle of the support member, a baffle being fixedly connected to the outer side of the stirring rod, an elastic connecting component being fixedly connected to the lower part of the output shaft of the motor, and a connecting component that engages with the elastic connecting component being fixedly connected to the top of the stirring rod.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a pharmaceutical lozenge production device, including a machine body 1, which is a rotary tablet press. It integrates core functional units such as a feeding hopper and a tablet pressing mechanism, providing a stable operating platform for the production of Dai medicine lozenges. This technology is existing technology and therefore will not be described in detail. A stirring mechanism 2 is installed on the outer side of the upper part of the feeding hopper of the machine body 1. This mechanism is specifically designed to solve the problem of clumping and accumulation of Dai medicine raw materials, such as *Lysimachia christinae* and *Sargassum fusiforme*, which contain sticky components. Its core function is to uniformly stir the Dai medicine raw materials in the feeding hopper, ensuring the quality of subsequent tablet pressing. The stirring mechanism 2... The mounting base 21, which is fixedly connected to the outside of the feed hopper of the machine body 1 by fixing bolts 5, provides a stable mounting point for the mounting cover 22, support 23 and other components of the mixing mechanism 2, ensuring the stability of the overall structure during the mixing process. The fixing bolts 5 are threaded to the inner wall of the mounting base 21 and pass through the feed hopper of the machine body 1. A crank is provided on the front side of the fixing bolts 5 for easy rotation by the operator. The mounting cover 22 is rotatably connected to the left side of the mounting base 21 and can be opened and closed. This not only closes the feed hopper to reduce the contamination of the Dai medicine raw materials by external impurities, but also facilitates the addition of raw materials and maintenance of internal components.

[0033] Reference Figure 3 , Figure 4 and Figure 7 A motor 3, a servo motor, is fixedly connected through the upper part of the mounting cover 22, serving as the power source for the stirring mechanism 2. It drives the elastic connecting assembly 26 to rotate via the output shaft, thereby driving the stirring rod 24 to rotate, providing continuous power for stirring the Dai medicinal materials and ensuring thorough dispersion of viscous materials. A support member 23 is fixedly connected to the inner wall of the mounting base 21, providing radial support for the stirring rod 24 and preventing it from shaking during rotation, which would affect the stirring effect. The stirring rod 24 is rotatably connected through the middle of the support member 23. The lower part of the stirring rod 24 is designed in a cross shape, allowing for thorough dispersion during rotation. To address the clumping in the raw materials of Dai medicine, the contact area with viscous materials is increased, improving stirring efficiency. A baffle 25 is fixedly connected to the outside of the stirring rod 24. The bottom of the baffle 25 contacts the outside of the support member 23 to support the stirring rod 24. The upper part of the baffle 25 is set as an inclined surface to reduce raw material residue. An elastic connecting component 26 is fixedly connected to the lower part of the output shaft of the motor 3 to realize the power transmission and detachable connection between the motor 3 and the stirring rod 24. A connecting component 27 is fixedly connected to the top of the stirring rod 24, which engages with the elastic connecting component 26 and cooperates with the connecting teeth 264 to transmit power. The stirring mechanism 2, auxiliary mechanism 4, and fixing bolts 5 are all made of food-grade stainless steel.

[0034] Reference Figure 3 - Figure 5The elastic connection assembly 26 includes a housing 261, which is fixedly connected to the lower part of the output shaft of the motor 3, providing installation space for the sliding member 262 and the return spring 263. The sliding member 262 is vertically slidably connected to the inner wall of the housing 261, transmitting power to the motor 3 as the output shaft of the motor 3 rotates. The lower part of the sliding member 262 has connecting teeth 264, and multiple sets of connecting teeth 264 are arranged in a circular array. The connecting teeth 264 engage with the connecting member 27 and with the strip-shaped protrusion of the connecting member 27, ensuring that the rotational power of the motor 3 is stably transmitted to the stirring element. The upper part of the stirring rod 24 and the sliding member 262 are elastically connected to the inner wall of the outer shell 261 by a return spring 263. When the mounting cover 22 is closed, the sliding member 262 is driven to press the connecting member 27. At this time, the return spring 263 provides elastic force to the sliding member 262, so that the sliding member 262 can slide, thereby avoiding direct hard collision. The upper part of the connecting member 27 is provided with multiple sets of strip protrusions with right-angled triangle cross sections. When the stirring rod 24 is driven to rotate, the connecting teeth 264 contact the vertical surface of the right-angled triangle strip protrusions, thereby driving the stirring rod 24 to rotate.

[0035] Reference Figure 3 and Figure 6 An auxiliary mechanism 4 is provided on the right side of the mounting base 21. The auxiliary mechanism 4 includes two sets of limiting members 41, which are horizontally slidably connected to the inner wall of the right side of the mounting base 21. The limiting members 41 are J-shaped and normally abut against the outside of the fixing member 44, firmly locking the fixing member 44 through the J-shaped hook to prevent the mounting cover 22 from opening accidentally during equipment operation, thus ensuring production safety. A pull rod 43 is fixedly connected to the right side of the two sets of limiting members 41. When pressed, it can drive the limiting members 41 to slide synchronously to the right, disengaging them from the fixing member 44, facilitating quick opening of the mounting cover 22 for adding Dai medicine raw materials or cleaning the feed hopper. The operation is convenient. The installation cover 22 is fast and efficient. A fixing member 44 is fixedly connected to the right side of the installation cover 22. It works with the limiting member 41 to lock and fix the installation cover 22, ensuring the sealing of the feed hopper during mixing and reducing raw material contamination. The fixing member 44 is snapped into the inner wall of the right side of the installation base 21, and the limiting member 41 abuts against the outer side of the fixing member 44. A spring piece 42 is provided on the left side of the limiting member 41 on the inner wall of the installation base 21. It is an elastic metal piece made of stainless steel, which provides continuous elastic force to push the limiting member 41 against the fixing member 44 to ensure the stability of the installation cover 22. When the installation cover 22 is opened, it is compressed and deformed. After being released, it automatically resets and locks.

[0036] Working principle: In use, the mounting base 21 of the stirring mechanism 2 is first fixedly to the outside of the feed hopper of the machine body 1 by fixing bolts 5 to ensure the stability of the overall structure. In the initial state, the mounting cover 22 is closed with the mounting base 21 through the auxiliary mechanism 4: the fixing piece 44 is inserted into the inner wall of the right side of the mounting base 21, and the spring piece 42 pushes the J-shaped limiting piece 41 to press against the outside of the fixing piece 44, thereby locking the mounting cover 22 and closing the feed hopper to reduce impurity contamination.

[0037] When adding Dai medicinal materials, press the lever 43 to move the limiting piece 41 to the left, compress the spring piece 42, and disengage the limiting piece 41 from the fixing piece 44. At this time, the mounting cover 22 can be opened around the rotating shaft on the left side of the mounting base 21, and the Dai medicinal materials containing sticky components such as lampstand leaves and bitter vine can be poured into the feed hopper. After closing the mounting cover 22, release the lever 43, and the spring piece 42 will reset and push the limiting piece 41 to re-clamp the fixing piece 44, thus completing the addition of materials and restoring the closed state.

[0038] At this time, the connecting teeth 264 of the elastic connecting component 26 contact the right-angled triangular strip protrusion on the upper part of the connector 27. Under the pressure of the return spring 263, the stirring rod 24 rotates through the inclined surface to achieve automatic alignment and insertion.

[0039] When the motor 3 is started, its output shaft drives the elastic connecting component 26 to rotate. The outer shell 261 rotates with the output shaft of the motor 3. The sliding part 262 engages with the right-angled triangular strip protrusion on the upper part of the connecting part 27 through the connecting teeth 264, transmitting power to the stirring rod 24. The cross-shaped stirring rod 24 rotates stably under the support of the support part 23, stirring the Dai medicine raw materials in the feed hopper, breaking up clumps and preventing accumulation.

[0040] The uniformly mixed Dai medicinal raw materials enter the tableting mechanism of machine body 1 to complete the subsequent tableting process. When production is completed or maintenance is required, the mounting base 21 can be removed by turning the handle of the fixing bolt 5, and the mounting cover 22 can be opened to clean or repair components such as the stirring rod 24 and the support 23. The operation is convenient and meets the cleanliness requirements of equipment in Dai medicinal production.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
