Description

Technical Field

[0001] This utility model belongs to the technical field of traditional Chinese medicine processing equipment, and in particular relates to an automatic cutting device for a high-efficiency pill-making machine for traditional Chinese medicine pills. Background Technology

[0002] Traditional Chinese medicine pills are one of the traditional dosage forms of Chinese medicine. With the continuous development of the modern Chinese medicine industry, the demand for the production of traditional Chinese medicine pills is increasing, and higher requirements are being placed on their production quality and efficiency.

[0003] Under existing granulation roller shearing and rounding mechanisms, when producing larger pills, the supply of strip-shaped medicinal materials needs to be significantly increased. The granulation rollers struggle to effectively shear and uniformly round more material, potentially leading to irregular shapes and inconsistent internal density in the larger pills during production. To address these issues, we provide an automatic slitting device for a high-efficiency pill-making machine for traditional Chinese medicine. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic cutting device for a high-efficiency pill-making machine for traditional Chinese medicine pills. By combining the ejection component and the pill-rolling component, it solves the problem that existing pill-making machines are prone to producing irregular shapes and different internal densities when making larger pills.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to an automatic slitting device for a high-efficiency pill-making machine for traditional Chinese medicine pills. It includes a support column, a screw extruder mounted on one side of the support column, a circular shell connected to the bottom outlet of the screw extruder, a slitting disc movably connected inside the circular shell, and a slitting hole inside the slitting disc. An ejection assembly is provided inside the slitting disc, comprising an ejection rod slidably connected inside the slitting disc, a slider mounted on one end of the ejection rod, a cam slidably connected to one side of the slider, and an ejection block slidably connected inside the slitting hole.

[0023] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1, please refer to Figures 1-4 This utility model relates to an automatic slitting device for a high-efficiency pill-making machine for traditional Chinese medicine pills. It includes a support column 1, with a screw extruder 2 mounted on one side of the support column 1. A circular shell 3 is connected to the bottom outlet of the screw extruder 2. When the screw extruder 2 is working, a motor drives the screw to rotate. The mixed traditional Chinese medicine is placed inside the barrel, and the screw groove pushes the medicine downwards. As the screw pitch gradually decreases and resistance at the die head increases, the medicine is continuously compacted and plasticized under pressure, eventually being extruded into strips through the die head. These strips are then discharged into the circular shell 3 and enter the slitting holes 5, completing the automatic feeding process. Simultaneously, the squeezing action of the screw extruder 2 keeps the medicine strips inside the slitting holes 5 tightly packed. A slitting disc 4 is movably connected inside the circular shell 3, and the slitting disc 4 has four slitting holes 5, allowing for simultaneous feeding and discharging of the medicine strips, thus improving the pill-making efficiency. To improve processing efficiency, the slitting disc 4 is equipped with an ejector assembly, which includes an ejector rod 6 slidably connected inside the slitting disc 4, a slider 7 installed at one end of the ejector rod 6, and a cam 8 slidably connected to one side of the slider 7. The cam 8 is located inside the slitting disc 4, and the protruding position of the cam 8 remains vertically downward. When the slitting disc 4 rotates, it can drive four sets of sliders 7 to slide on the surface of the cam 8. An ejector block 9 is slidably connected inside the slitting hole 5. A shot-rolling assembly is provided on one side of the support column 1. The shot-rolling assembly includes a guide rail plate 10 installed on one side of the support column 1. The shot-rolling groove 11 at the top of the guide rail plate 10 and the shot-rolling plate 12 at the bottom form a circular channel. The inner wall of the shot-rolling groove 11 has a friction coating. When pushing the medicine strip, it can roll the medicine strip into a circle. The shot-rolling groove 11 is opened at the top of the guide rail plate 10, and the shot-rolling plate 12 is slidably connected to the top of the guide rail plate 10.

[0025] Example 2, please refer to Figures 1-4 Based on Embodiment 1, the shot rubbing assembly also includes a hydraulic rod 13 installed at the bottom of the guide rail plate 10. The output end of the hydraulic rod 13 is fixedly connected to the shot rubbing plate 12. A discharge groove 14 is provided at the bottom of the circular shell 3. A baffle column 15 is installed inside the discharge groove 14. A drive motor 16 is installed on one side of the support column 1. A drive shaft 17 is installed at the output end of the drive motor 16. The other end of the drive shaft 17 is fixedly connected to the slitting disc 4. The surface of the slitting disc 4 is movably connected to the inner wall of the circular shell 3 through a bearing. One side of the circular shell 3 is fixedly connected to the support column 1 through a crossbar. A spring 18 is sleeved on the surface of the ejector rod 6. The spring 18 has the function of compression and energy storage, which can reset the ejector rod 6. One end of the spring 18 is fixedly connected to the slider 7. A crossbar 19 is fixedly connected to one side of the cam 8. A column 20 is fixedly connected to the other end of the crossbar 19. The bottom of the column 20 is fixedly connected to the support column 1. A collection shell 21 is provided on one side of the column 20.

[0026] The working principle of this utility model is as follows: The operator starts the screw extruder 2, which extrudes the medicine strip into shape and then conveys it downward to the circular shell 3 and into the slitting hole 5. The capacity of the slitting hole 5 is the weight of a single pill. Then, the drive motor 16 is started. The drive motor 16, together with the drive shaft 17, drives the slitting disc 4 to rotate. When the slitting disc 4 rotates, it divides the medicine strip and continues to rotate 180 degrees with the drive shaft 17 as the axis. At the same time as the slitting disc 4 rotates, it drives the slider 7 to slide on the surface of the cam 8. When the slider 7 rotates to the protruding position at the bottom of the cam 8, the cam 8 can push the slider 7 and the ejector rod 6 to move. The ejector rod 6 drives the ejector block 9 to move, pushing the medicine strip in the slitting hole 5 out of the slitting disc 4. When the slitting disc 4 continues to rotate, the medicine strip can contact the baffle post 15 and be pushed into the pill rolling groove 11 by the baffle post 15.

[0027] Then, the hydraulic rod 13 is activated, which drives the pellet rolling plate 12 to move. The pellet rolling groove 11 at the top of the guide plate 10 and the bottom of the pellet rolling plate 12 form a circular channel. When pushing the medicine strip, the medicine strip can be rolled into a circle. Then, the pellet rolling plate 12 continues to move. When the pellet rolling plate 12 moves, it can push the pill to continue to rotate until it falls into the collection shell 21. In this way, the density and weight of the processed pills can be kept uniform, which is suitable for mass production of large-particle Chinese medicine pills and improves the processing efficiency of the pills.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
