[0019] like Figures 1-5 As shown, a tableting structure for processing traditional Chinese medicine includes: Fixed base 1, wherein a material discharge port 11 is opened on the upper right rear side of the fixed base 1; Rotary disk 2 is rotatably connected to the upper end of fixed base 1. Four Chinese herbal medicine grooves 21 are evenly opened in a ring on the outer side of the upper end of the rotary disk 2. The Chinese herbal medicine groove 21 on the right rear side is located on the same vertical line as the material discharge port 11. The Chinese herbal medicine grooves 21 on the rotary disk 2 are used to place Chinese herbal medicine particles. In this way, the Chinese herbal medicine particles will be located on the upper end of fixed base 1. When the rotary disk 2 rotates, it can drive the Chinese herbal medicine particles to move together. An intermittent motion mechanism 3 is installed at the lower end of the fixed base 1 and connected to the rotating disk 2. The intermittent motion mechanism 3 drives the rotating disk 2 to rotate horizontally at an intermittent 90-degree angle. The intermittent motion mechanism 3 includes a transmission box 31, a rotating shaft 32, a grooved wheel 33, a dial 34, and a round pin 35. The transmission box 31 is fixed at the lower end of the fixed base 1. The rotating shaft 32 is rotatably connected inside the transmission box 31. The upper part of the rotating shaft 32 movably passes through the fixed base 1 and is fixed to the rotating disk 2. The grooved wheel 33 is fixed... The dial 34 is located outside the rotating shaft 32 and is rotatably connected to the inside of the transmission box 31 on one side of the grooved wheel 33. The round pin 35 is fixed to the side of the dial 34 and is inserted into the groove on the outer wall of the grooved wheel 33. The intermittent motion mechanism 3 also includes a rotary encoder 36, a permanent magnet synchronous motor 37, and a PLC controller 38. The permanent magnet synchronous motor 37 is fixedly installed at the lower end of the transmission box 31, and its output shaft is fixed to the dial 34. The rotary encoder 36 is located on one side of the permanent magnet synchronous motor 37 and is fixedly installed at the lower end of the transmission box 31. Its input shaft is fixed to the lower part of the rotating shaft 32. The PLC controller 38 is located on the other side of the permanent magnet synchronous motor 37 and is fixedly installed at the lower end of the transmission box 31. The rotary encoder 36 is signal-connected to the PLC controller 38, and the PLC controller 38 is signal-connected to the permanent magnet synchronous motor 37. The permanent magnet synchronous motor 37 drives the dial 34 to rotate clockwise one revolution, which in turn drives the round pin 35 to move in a circular motion. During this process, the pin 35 will slide into the groove at the left rear end of the grooved wheel 33 and move out of the groove when the groove moves to the left front end. During this process, the grooved wheel 33 will rotate 90 degrees counterclockwise. In this way, the grooved wheel 33 can drive the rotating disk 2 to rotate 90 degrees counterclockwise through the rotating shaft 32. At the same time, the rotating shaft 32 drives the input shaft of the rotary encoder 36 to rotate 90 degrees. Then the rotary encoder 36 sends the rotation signal to the PLC controller 38, and the PLC controller 38 controls the permanent magnet synchronous motor 37 to stop. A tablet pressing mechanism 4 is fixedly installed on the right end of a fixed base 1. The tablet pressing mechanism 4 is inserted into the herbal medicine troughs 21 on the right front and right rear sides. The tablet pressing mechanism 4 includes an electric cylinder 41, an L-shaped connecting arm 42, a concave pressure rod 43, a force sensor 44, a first pressure plate 45, and a second pressure plate 46. The electric cylinder 41 is fixedly installed on the fixed base 1. The L-shaped connecting arm 42 is fixed to the upper actuating end of the electric cylinder 41. The concave pressure rod 43 is fixed to the end of the L-shaped connecting arm 42. The force sensor 44 is fixedly installed at the lower front end of the concave pressure rod 43. The first pressure plate 45 is fixedly installed at the lower end of the force sensor 44. The force sensor 44 is signal-connected to a PLC controller 38, which is also signal-connected to the electric cylinder 41. The second pressure plate 46 is fixedly installed at the lower rear end of the concave pressure rod 43. While the PLC controller 38 controls the permanent magnet synchronous motor 37 to stop, it can also control the electric cylinder 41 to move the L-shaped connecting arm 42 downwards. The L-shaped connecting arm 42 drives the concave pressure rod 43 to move downwards. This causes the concave pressure rod 43 to move the first pressure plate 45 and the second pressure plate 46 downwards together. The first pressure plate 45 moves downwards and inserts into the right front side of the herbal medicine trough 21 to compress the herbal medicine granules into tablets. The second pressure plate 46 moves downwards and inserts into the right rear side of the herbal medicine trough 21 to push out the compressed herbal medicine tablets. Because the lower end face of the second pressure plate 46 is lower than the lower end face of the first pressure plate 45, the second pressure plate 46 will first insert into the right rear side... The herbal medicine trough 21 is used to ensure that the herbal medicine slices after compression can be pushed out of the herbal medicine trough 21 and fall from the material outlet 11 during the tableting process. When the pressure value received by the force sensor 44 exceeds the threshold set in the PLC controller 38, a signal can be sent to the PLC controller 38. The PLC controller 38 then controls the electric cylinder 41 to extend, so as to drive the first pressure plate 45 and the second pressure plate 46 to move upward together. After that, the PLC controller 38 will control the permanent magnet synchronous motor 37 to start. The hopper mechanism 5 is fixed to the left rear side of the fixed base 1. The hopper mechanism 5 and the herbal medicine trough 21 on the left rear side are on the same vertical line. The hopper mechanism 5 includes a sleeve 51, a sliding rod 52, a fixed plate 53, and a hopper 54. The sleeve 51 is fixed to the fixed base 1. The sliding rod 52 is slidably connected inside the sleeve 51. The upper part of the sliding rod 52 extends out of the sleeve 51 and is fixed to the fixed plate 53. The hopper 54 is fixed to the front of the fixed plate 53. Herbal medicine granules are pre-stored inside the hopper 54. During the rotation of the rotating disk 2, the bottom of the hopper 54 slides against the upper end of the rotating disk 2. When the rotating disk 2 rotates to the point where the herbal medicine trough 21 on the left rear side is on the same vertical line as the hopper 54, the herbal medicine granules inside the hopper 54 fall into the herbal medicine trough 21 due to gravity. Thus, feeding is carried out simultaneously during the tableting and feeding process.
[0020] A sealing ring 55 is fixedly connected to the lower end of the hopper 54. The sealing ring 55 is in contact with the rotating disk 2. When the bottom of the hopper 54 slides with the upper end of the rotating disk 2, the sealing ring 55 directly contacts the rotating disk 2, which can improve the sealing between the hopper 54 and the rotating disk 2.
[0021] A spring 56 connects the lower part of the slide rod 52 to the upper part of the sleeve 51. A rectangular guide channel 58 is opened at the center of the lower part of the slide rod 52. A rectangular guide rod 57 is fixed at the center of the lower end of the sleeve 51. The upper part of the rectangular guide rod 57 extends into the rectangular guide channel 58 and slides in connection with the rectangular guide channel 58. The spring 56 can give the slide rod 52 a downward elastic force. The cooperation between the rectangular guide rod 57 and the rectangular guide channel 58 can prevent the slide rod 52 from rotating, thus preventing the hopper 54 from shifting and ensuring that the hopper 54 is in close contact with the rotating disk 2.
[0022] Working principle: First, the hopper 54 pre-stores medicinal herb granules, which are conveyed into the hopper 54 by an automatic conveyor. Then, the permanent magnet synchronous motor 37 drives the dial 34 to rotate clockwise once, which in turn drives the pin 35 to rotate once. During this process, the pin 35 slides into the groove at the left rear end of the grooved wheel 33 and moves out of the groove when it reaches the left front end. During this process, the grooved wheel 33 rotates counterclockwise by 90 degrees. Thus, the grooved wheel 33 drives the rotating disk 2 to rotate counterclockwise by 90 degrees via the rotating shaft 32. When the medicinal herb trough 21 on the left rear side is on the same vertical line as the hopper 54, the medicinal herb granules inside the hopper 54 fall into the medicinal herb trough 21 due to gravity. At the same time, the rotating shaft 32 drives the input shaft of the rotary encoder 36 to rotate 90 degrees. Then, the rotary encoder 36 sends the rotation signal to the PLC controller 38. The PLC controller 38 stops the permanent magnet synchronous motor 37 and simultaneously controls the electric cylinder 41 to retract, causing the L-shaped connecting arm 42 to move downwards. The L-shaped connecting arm 42 then causes the concave pressure rod 43 to move downwards. This causes the concave pressure rod 43 to move the first pressure plate 45 and the second pressure plate 46 downwards together. The first pressure plate 45 moves downwards and inserts into the Chinese herbal medicine trough 21 on the right front side to compress the Chinese herbal medicine granules into tablets. The second pressure plate 46 moves downwards and inserts into the Chinese herbal medicine trough 21 on the right rear side to push the compressed Chinese herbal medicine tablets out of the trough 21 and fall from the discharge port 11. When the pressure value received by the force sensor 44 on the first pressure plate 45 exceeds the threshold set in the PLC controller 38, the PLC controller 38 controls the electric cylinder 41 to extend, causing the first pressure plate 45 and the second pressure plate 46 to move upwards together. Afterwards, the PLC controller 38 also controls the permanent magnet synchronous motor 37 to start, thus performing the next round of feeding, tableting, and unloading synchronously.
[0023] The rotary encoder 36, permanent magnet synchronous motor 37, PLC controller 38, electric cylinder 41 and force sensor 44 mentioned above are all externally powered.
