The output shaft of the second rotating motor 10 passes into the first mixing chamber 5 and is fixedly connected to the right end of a horizontally positioned stirring shaft 16. The left end of the stirring shaft 16 is rotatably connected to the center of the left inner wall of the first mixing chamber 5, ensuring stable rotation of the stirring shaft 16. Multiple stirring rods 17 are provided on the stirring shaft 16. The stirring rods 17 are N-shaped, which increases the contact area between the stirring rods and the material, improving the mixing effect and allowing the material to be more thoroughly mixed within the first mixing chamber 5.
[0030] Furthermore, the second mixing unit 2 includes a second mixing chamber 12, a discharge port 14, a stirring mechanism, and a discharge pipe 13. The second mixing chamber 12 is vertically arranged, and the first mixing unit 1 is located on the upper surface of the second mixing chamber 12. The upper surface of the second mixing chamber 12 is provided with a discharge port 14 and a feeding port 4. The discharge port 14 is located directly below the first mixing chamber 5 and is configured to cooperate with the material outlet sealing door 11. When the material outlet sealing door 11 is opened, the pre-mixed material in the first mixing chamber 5 can fall into the second mixing chamber 12 through the discharge port 14. The feeding port 4 is used to add other materials or additives to the second mixing chamber 12. The lower surface of the second mixing chamber 12 is provided with a discharge port, and an electric gate 18 is provided at the discharge port to control the discharge of materials. The discharge pipe 13 is inclinedly arranged on the lower end face of the second mixing chamber 12. The inlet end of the discharge pipe 13 is connected to the discharge port, and the outlet end of the discharge pipe 13 is equipped with a solenoid valve 19. When the electric gate 18 is opened and the solenoid valve 19 is opened, the mixed material can be discharged through the discharge pipe 13. The stirring mechanism is arranged inside the second mixing chamber 12.
[0031] Furthermore, the stirring mechanism includes a third rotary motor 15, a second stirring shaft 20, two scraper frames 21, two scrapers 22, and multiple stirring blades 23. The third rotary motor 15 is located in the middle of the lower end face of the second mixing chamber 12. The output shaft of the third rotary motor 15 extends vertically upward into the second mixing chamber 12 and is fixedly connected to the lower end of the vertically arranged second stirring shaft 20. The upper end of the second stirring shaft 20 is rotatably connected to the middle of the inner top wall of the second mixing chamber 12 to ensure stable rotation of the second stirring shaft 20. Scraper frames 21 are symmetrically arranged on the second stirring shaft 20, and the scraper frames 21 are shaped according to the inner wall of the second mixing chamber 12. Scrapers 22 are provided on the outer walls of both scraper frames 21. The scrapers 22 are fitted against the inner wall of the second mixing chamber 12 to better fit the inner wall of the second mixing chamber 12. The scrapers 22 are made of rubber, which has good flexibility and wear resistance, and can scrape off residual materials on the inner wall of the second mixing chamber 12 during the stirring process, reducing material waste. Multiple stirring blades 23 are arranged in two groups. One group is vertically arranged on one of the scraper frames 21, and the other group is horizontally arranged on the stirring shaft 20. This arrangement of stirring blades in different directions enables the material to form multi-dimensional mixing in the second mixing chamber 12, further improving the mixing effect.
[0032] I. Working Principle
[0033] This mixing device for preparing chewable tablets is designed specifically for the preparation characteristics of Penyanjing chewable tablets, employing a working principle that combines multi-stage mixing with high-efficiency stirring. In the first mixing unit 1, the rotation of the first mixing chamber 5 and the stirring action of the internal stirring rod 17 ensure that the raw materials for Penyanjing chewable tablets are initially mixed evenly, breaking down the agglomeration between raw materials and increasing the contact area between materials. Subsequently, the initially mixed material falls into the second mixing chamber 12. In the second mixing unit 2, the multi-dimensional stirring of the stirring mechanism and the scraping action of the scraper 22 on the chamber wall further ensure the thorough mixing of the raw materials for Penyanjing chewable tablets, resulting in a uniform distribution of various components and improving the consistency and stability of product quality.
[0034] II. Work Process
[0035] 1. Feeding stage
[0036] Raw material preparation: According to the formula of Penyanjing chewable tablets, accurately weigh the required Chinese herbal extracts and excipients such as fillers, disintegrants, and flavoring agents. For example, the Chinese herbal extracts may contain the effective components of honeysuckle vine, chicken blood vine, and cibotium barometz after extraction and concentration, while the excipients are selected according to the taste and shaping requirements of the chewable tablets.
[0037] Open the material inlet sealing door 11: The operator can manually or via a control device open the material inlet sealing door 11 on the side wall of the first mixing chamber 5. The material inlet sealing door 11 employs a reliable sealing structure to ensure that no material leakage occurs during the mixing process.
[0038] Raw material input: Slowly add the weighed raw materials for Penyanjing chewable tablets into the first mixing chamber 5. During the input process, care should be taken to avoid spilling raw materials outside the first mixing chamber 5, which would affect the mixing effect and production efficiency.
[0039] Close the material inlet sealing door 11: After the raw materials are fed in, close the material inlet sealing door 11 in time to ensure that the first mixing chamber 5 is in a sealed state, in preparation for subsequent mixing operations.
[0040] 2. First stage of mixing
[0041] Start Rotary Motor 9: Start Rotary Motor 9 via the control panel. Rotary Motor 9 is an AC asynchronous motor with stable output torque and speed regulation. Its output shaft drives the first mixing chamber 5 to rotate slowly around the axis of the rotating ring 7. The rotation speed can be adjusted according to the properties of the raw materials and mixing requirements.
[0042] Start the second rotating motor 10: Simultaneously, start the second rotating motor 10. The second rotating motor 10 is also an AC asynchronous motor, and its output shaft drives the first stirring shaft 16 to rotate. The stirring rod 17 on the first stirring shaft 16 has an N-shaped design, which increases the contact area between the stirring rod 17 and the material, improving the stirring efficiency. During the rotation of the stirring rod 17, the raw material of the Penyanjing chewable tablets in the first mixing chamber 5 is stirred, so that the raw material is initially mixed evenly under the combined action of rotation and stirring. The stirring time can be set according to the actual situation.
[0043] Mixing Process Monitoring: During the mixing process, operators can monitor the mixing status within the first mixing chamber 5 through an observation window or sensors (not shown in the attached diagram). The observation window is made of transparent, pressure-resistant material, allowing for a clear view of the material's mixing state. Sensors can monitor parameters such as temperature and humidity in real time during the mixing process, ensuring that the mixing process takes place under suitable environmental conditions.
[0044] 3. Material feeding stage
[0045] Opening the material inlet sealing door 11: After the first stage of mixing is completed, the operator opens the material inlet sealing door 11 by turning it toward the discharge port 14 using the control device. The opening angle of the material inlet sealing door can be adjusted as needed to ensure that the material can smoothly pass through the discharge port 14 and fall into the second mixing chamber 12.
[0046] Material falls into the second mixing chamber 12: Under the influence of gravity, the raw material of Penyanjing chewable tablets in the first mixing chamber 5 falls into the second mixing chamber 12 through the discharge port 14. The size and shape of the discharge port 14 are designed to ensure smooth material flow while preventing blockage during the material flow process.
[0047] 4. Second-level mixing stage
[0048] Start the rotating motor 315: After all the material has fallen into the second mixing chamber 12, start the rotating motor 315. The rotating motor 315 is a high-efficiency and energy-saving motor, and its output shaft drives the stirring shaft 20 to rotate. The stirring shaft 20 is symmetrically equipped with scraper racks 21 on the left and right sides. The scraper racks 21 are set according to the shape of the inner wall of the second mixing chamber 12, so as to better fit the inner wall of the second mixing chamber 12.
[0049] Multi-dimensional mixing: The mixing blades 23 on the second mixing shaft 20 are arranged in two groups. One group is vertically mounted on one of the scraper frames 21, and the other group is horizontally mounted on the second mixing shaft 20. This arrangement of mixing blades in different directions enables the material to undergo multi-dimensional mixing within the second mixing chamber 12, further improving the mixing effect. Simultaneously, the scraper 22 on the outer wall of the scraper frame 21 scrapes away residual material from the inner wall of the second mixing chamber 12 as the second mixing shaft 20 rotates. The scraper 22 is made of rubber, possessing good flexibility and wear resistance, and can scrape away material while avoiding damage to the chamber wall.
[0050] Mixing time control: The mixing time for the second stage is set according to the formula and mixing requirements of the Penyanjing chewable tablets. During the mixing process, the rotation speed of the rotary motor can be adjusted as needed to achieve the best mixing effect.
[0051] 5. Material Discharge Stage
[0052] Opening the electric gate 18 and solenoid valve 19: After the raw materials for Penyanjing chewable tablets are evenly mixed, the operator opens the electric gate 18 and solenoid valve 19 through the control device. The electric gate 18 is driven by an electric push rod, which can quickly and accurately open and close the discharge port. The solenoid valve 19 has the characteristics of fast response speed and good sealing performance, which can ensure the smooth progress of the discharge process.
[0053] Material Discharge: The mixed raw materials for Penyanjing chewable tablets are discharged through the discharge port and discharge pipe 13. The discharge pipe 13 is inclined, and the inclination angle of the discharge pipe 13 facilitates the smooth discharge of materials. During the discharge process, the operator can use a container to collect the discharged materials, preparing for the subsequent tableting process.
[0054] After discharge, clean the mixing device. First, close the electric gate 18 and the solenoid valve 19. Then, use clean water or detergent to rinse the first mixing chamber 5, the second mixing chamber 12, and the stirring mechanism to remove residual materials and impurities. After cleaning, air dry or bake the device for future use.
[0055] This invention relates to a mixing device for preparing chewable tablets, which effectively mixes the raw materials for Penyanjing chewable tablets, ensuring product quality and production efficiency. In actual production, parameters and operating steps can be adjusted appropriately according to specific circumstances to achieve the best mixing effect.
