Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing technology, specifically to a homogenizing and mixing device for powdered medicinal materials in pharmaceutical processing. Background Technology

[0002] Pharmaceutical processing is an important link in the pharmaceutical industry chain. It involves processing raw materials into drugs that can be directly used in clinical practice through a series of processes. The pharmaceutical processing industry also includes the processing of Chinese herbal medicine pieces and the manufacturing of traditional Chinese medicine preparations.

[0003] A pharmaceutical powder homogenizing and mixing device, also known as a pharmaceutical mixer, is a machine specifically designed to mix two or more drugs in a certain proportion. The main structure of a pharmaceutical mixer includes a main body, a mixing tank, a stirrer, and a sealing cover. Among these, the stirrer is the core component, which achieves uniform mixing of drugs through its rotational motion. During the mixing process, the design and movement of the stirrer have a significant impact on the mixing effect.

[0004] The prior art patent document CN220878610U provides a homogenizing and mixing device for pharmaceutical processing of powdered medicinal materials. This device, by setting a transmission structure on the processing box, allows the drive mechanism to drive the transmission structure to move the stirring rod back and forth while also rotating it. This allows the device to move within the processing box while mixing the powdered medicinal materials, expanding the mixing range and effectively improving the homogenizing and mixing efficiency of the powdered medicinal materials.

[0005] The aforementioned prior art, although the mixing device drives the stirring rod to reciprocate and rotate through a transmission structure, thereby moving within the processing chamber while mixing powdered medicinal materials and expanding the mixing range, cannot further pulverize or sieve the medicinal materials during use. When grinding the medicinal materials into powder, a small portion may not be completely pulverized, and some medicinal material particles may be too large to be mixed as powdered drugs, affecting the mixing effect. This necessitates manual grinding and sieving, which greatly reduces work efficiency. Therefore, we need a homogenizing mixing device for powdered medicinal materials in pharmaceutical processing. Utility Model Content

[0006] The purpose of this invention is to provide a homogenizing and mixing device for powdered medicinal materials in pharmaceutical processing, in order to solve the problem mentioned in the background art that the mixing device cannot further pulverize or sieve the medicinal materials during use. When the medicinal materials are ground into powder, a small part may not be completely pulverized, and some medicinal material particles may be too large. This makes it impossible to mix some powdered drugs, which will affect the mixing effect. Therefore, manual grinding and sieving are required, which greatly reduces the work efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A homogenizing and mixing device for powdered medicinal materials in pharmaceutical processing includes a mixing drum, a support leg fixedly connected to the bottom of the mixing drum, a sieving component installed inside the mixing drum, and a discharge component provided at the bottom of the mixing drum.

[0009] The screening assembly includes a motor, the output end of which is detachably connected to a first transmission rod via a coupling, and a first striking block is provided at one end of the first transmission rod. A pulley assembly is rotatably connected to the outer wall of the first transmission rod, and a second transmission rod is provided on the inner wall of the pulley assembly. A second striking block is installed at one end of the second transmission rod. A first screen is slidably connected to the inner wall of the mixing tank, and a spring is installed on the top of the first screen. A second screen is provided on the top of the spring.

[0010] The discharge assembly includes a discharge port, a first rotating shaft is provided on one side of the discharge port, and a connecting block is rotatably connected inside the first rotating shaft. An adjusting plate is fixedly connected to one side of the connecting block. A second rotating shaft is installed on the inner wall of the discharge port, and a hydraulic cylinder is rotatably connected inside the second rotating shaft. A third rotating shaft is provided at the bottom of the hydraulic cylinder.

[0011] Preferably, the mixing tank is equipped with a stirring mechanism inside, and the top of the mixing tank is provided with a feed inlet.

[0012] Preferably, the motor forms a rotating structure with the first striking block via a first transmission rod, and the first transmission rod is installed between the motor and the first striking block.

[0013] Preferably, the first transmission rod forms a rotating structure with the second transmission rod through a pulley assembly, and the pulley assembly is installed between the first transmission rod and the second transmission rod. The pulley assembly forms a rotating structure with the second impact block through the second transmission rod.

[0014] Preferably, the first screen and the second screen form an elastic structure through springs, and the number of springs is two.

[0015] Preferably, the discharge port forms a rotating structure with the connecting block via the first rotating shaft, and the connecting block is installed on one side of the discharge port. The first rotating shaft forms a rotating structure with the adjusting plate via the connecting block.

[0016] Preferably, the second rotating shaft forms a movable structure with the third rotating shaft via a hydraulic cylinder, and the hydraulic cylinder is installed between the second rotating shaft and the third rotating shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this is a homogenizing and mixing device for powdered medicinal materials in pharmaceutical processing.

[0018] Firstly, this utility model includes a motor, a first transmission rod, a first striking block, a pulley assembly, a second transmission rod, a second striking block, a first screen, a spring, and a second screen. Starting the motor drives the first transmission rod to rotate, which in turn drives the first striking block to rotate. The rotation of the first striking block causes it to strike and vibrate the first screen, thus sieving the powdered medicinal materials on both screens. The first and second screens are connected by a spring; when struck, the spring's elasticity generates vibration, effectively vibrating and sieving the powdered medicinal materials on both screens. This assembly eliminates the need for manual sieving, significantly improving work efficiency.

[0019] Secondly, this utility model is equipped with a discharge port, a first rotating shaft, a connecting block, an adjusting plate, a second rotating shaft, a hydraulic cylinder, and a third rotating shaft. After the medicinal materials are mixed, they need to be discharged. The extension and retraction of the hydraulic cylinder can move the third rotating shaft. The movement and rotation of the third rotating shaft can cause the adjusting plate to rotate and open. When the adjusting plate rotates, the first rotating shaft also rotates simultaneously through the connection of the connecting block. This can keep the rotation of the adjusting plate balanced and stable. The setting of this component can automatically adjust the opening and closing of the discharge port and control the discharge amount, thus increasing its practicality. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A homogenizing and mixing device for powdered medicinal materials in pharmaceutical processing includes a mixing tank 1, a support leg 2 fixedly connected to the bottom of the mixing tank 1, a sieving component 3 installed inside the mixing tank 1, and a discharge component 6 provided at the bottom of the mixing tank 1.

[0027] The screening assembly 3 includes a motor 301. The output end of the motor 301 is detachably connected to a first transmission rod 302 via a coupling. A first striking block 303 is provided at one end of the first transmission rod 302. A pulley group 304 is rotatably connected to the outer wall of the first transmission rod 302. A second transmission rod 305 is provided on the inner wall of the pulley group 304. A second striking block 306 is installed at one end of the second transmission rod 305. A first screen 307 is slidably connected to the inner wall of the mixing tank 1. A spring 308 is installed on the top of the first screen 307. A second screen 309 is provided on the top of the spring 308.

[0028] The discharge assembly 6 includes a discharge port 601. A first rotating shaft 602 is provided on one side of the discharge port 601, and a connecting block 603 is rotatably connected inside the first rotating shaft 602. An adjusting plate 604 is fixedly connected to one side of the connecting block 603. A second rotating shaft 605 is installed on the inner wall of the discharge port 601, and a hydraulic cylinder 606 is rotatably connected inside the second rotating shaft 605. A third rotating shaft 607 is provided at the bottom of the hydraulic cylinder 606.

[0029] Through the above technical solution, starting the motor 301 drives the first transmission rod 302 to rotate, which in turn drives the first striking block 303 to rotate. The rotation of the first striking block 303 causes it to vibrate and sieve the first screen 307. Simultaneously, the rotation of the first transmission rod 302, connected by the pulley group 304, drives the second transmission rod 305 to rotate, which in turn causes the second striking block 306 to rotate. The second striking block 306 rotates synchronously with the first striking block 303, causing it to strike the second screen 309. The first screen 307 and the second screen 309 are connected by a spring 308. When struck, the elasticity of the spring 308 generates vibration, thereby achieving the effect of vibrating and sieving the powdered medicinal materials on the first screen 307 and the second screen 309. This component can perform the sieving function without manual sieving, greatly improving work efficiency.

[0030] Specifically, the mixing tank 1 is equipped with a stirring mechanism 4 inside, and a feed inlet 5 is provided on the top of the mixing tank 1.

[0031] Through the above technical solution, the stirring mechanism 4 can be used to stir and mix the sieved powdered medicinal materials without the need for manual mixing, thus improving work efficiency. The feed inlet 5 allows personnel to easily put the raw materials into the mixing tank 1 for mixing.

[0032] Specifically, the motor 301 forms a rotating structure with the first striking block 303 through the first transmission rod 302, and the first transmission rod 302 is installed between the motor 301 and the first striking block 303.

[0033] Through the above technical solution, the motor 301 drives the first transmission rod 302 to rotate, which in turn drives the first striking block 303 to rotate. The rotation of the first striking block 303 causes it to strike and vibrate the first screen 307, thereby achieving the function of vibrating screening.

[0034] Specifically, the first transmission rod 302 forms a rotating structure with the second transmission rod 305 through the pulley assembly 304, and the pulley assembly 304 is installed between the first transmission rod 302 and the second transmission rod 305. The pulley assembly 304 forms a rotating structure with the second impact block 306 through the second transmission rod 305.

[0035] Through the above technical solution, the pulley assembly 304 consists of two pulleys and a belt. The first transmission rod 302 drives one pulley to rotate, and through the belt connection, it drives the other pulley to rotate synchronously. The rotation of the other pulley causes the second transmission rod 305 to rotate, which in turn drives the second striking block 306 to rotate and strike. The pulley assembly 304 plays the role of transmitting power in this device.

[0036] Specifically, the first screen 307 and the second screen 309 form an elastic structure through springs 308, and there are two springs 308.

[0037] Through the above technical solution, the first screen 307 and the second screen 309 are connected by a spring 308. When they are struck, the elasticity of the spring 308 can generate a vibration effect, which can achieve the effect of vibration screening of the powdered medicinal materials on the first screen 307 and the second screen 309. Since the aperture sizes of the first screen 307 and the second screen 309 are different, they can play a further screening role.

[0038] Specifically, the discharge port 601 forms a rotating structure with the connecting block 603 via the first rotating shaft 602, and the connecting block 603 is installed on one side of the discharge port 601. The first rotating shaft 602 forms a rotating structure with the adjusting plate 604 via the connecting block 603.

[0039] Through the above technical solution, the rotation of the first rotating shaft 602 can drive the connecting block 603 to rotate, and the connection of the connecting block 603 can enable the adjusting plate 604 to rotate, thus playing an auxiliary role in the rotation of the adjusting plate 604.

[0040] Specifically, the second rotating shaft 605 forms a movable structure with the third rotating shaft 607 via a hydraulic cylinder 606, and the hydraulic cylinder 606 is installed between the second rotating shaft 605 and the third rotating shaft 607.

[0041] Through the above technical solution, the extension and retraction of the hydraulic cylinder 606 pushes the third rotating shaft 607, and the rotation of the third rotating shaft 607 enables the adjusting plate 604 to rotate and open, thus adjusting the size of the opening and facilitating the control of the discharge amount.

[0042] Working Principle: When using this pharmaceutical powder homogenizing and mixing device, the raw materials are first manually fed into the mixing drum 1 through the feed inlet 5. The motor 301 is then started, driving the first transmission rod 302 to rotate. This rotation of the first transmission rod 302 drives the first striking block 303 to rotate, and simultaneously causes the pulley assembly 304 to rotate. Through the pulley assembly 304, the second transmission rod 305 rotates, causing the second striking block 306 to rotate synchronously with the first striking block 303. This causes the first screen 307 and the second screen 309 to be struck. The first screen 307 and the second screen 309 are then connected by the spring 308. The material rebounds, generating vibration to vibrate and sieve the powdered medicinal materials. During the sieving process, the stirring mechanism 4 is activated to mix the sieved powdered medicinal materials. After mixing, the hydraulic cylinder 606 is activated, and the extension and retraction of the hydraulic cylinder 606 pushes the third rotating shaft 607. The rotation of the third rotating shaft 607 opens the adjusting plate 604. The rotation of the first rotating shaft 602 assists in the rotation of the adjusting plate 604. This completes the opening and closing of the discharge port 601, thus completing all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit defined by the appended claims and their equivalents.
