Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0032] Example: A drug tableting machine that facilitates automatic feeding and unloading, such as... Figs. 1-3 As shown, the device includes a pressure table 1, a cavity 2 inside the pressure table 1, a rotating shaft 3 rotatably connected inside the cavity 2, a drive motor 13 on the pressure table 1, the drive motor 13 driving the rotating shaft 3 to rotate, a cylinder 4 fixedly sleeved on the outer wall of the rotating shaft 3, four grooves 5 evenly arranged along the outer circumference of the cylinder 4, a mold 6 fixedly mounted in the grooves 5, a buffer spring 7 fixedly mounted between the grooves 5 and the mold 6, one end of the buffer spring 7 fixedly connected to the mold 6, the other end fixedly connected to the bottom of the groove 5, a circular baffle 8 fixedly mounted inside the cavity 2, the baffle 8 slidably connected to and abutting against the outer wall of the cylinder 4, the baffle 8 having an upper opening, a lower opening, and a right opening on the top, bottom, and right sides respectively, a pressure assembly 9 above the upper opening, the pressure assembly 9... The device includes a hydraulic cylinder 91 and a pressing block 92. The hydraulic cylinder 91 is fixedly mounted on the pressing table 1. The right opening is connected to the feeding channel 10. The feeding channel 10 is equipped with a pushing assembly 11 and a feeding assembly 12 at the inlet. The pushing assembly 11 includes a cylinder 111 and a pushing plate 112. The cylinder 111 is fixedly mounted on the pressing table 1. The feeding assembly 12 includes a storage hopper 121 with a sealing cover 17. The bottom of the storage hopper 121 is equipped with a powder solenoid valve 122 connected to the feeding pipe 123. The feeding pipe 123 is connected to the feeding channel 10 and is located between the cylinder 111 and the right opening. The lower opening is equipped with a discharge channel 14. Below the discharge channel 14 is a tablet storage box 15 with a rubber buffer pad 16 at the bottom.
[0033] Working principle: The drive motor 13 on the pressure table 1 is started to drive the rotating shaft 3 to rotate, which in turn causes the cylinder 4 on the outer wall of the rotating shaft 3 to rotate synchronously. When the groove 5 of the cylinder 4 rotates to the feeding channel 10 which is connected to the right opening of the circular baffle 8, the feeding assembly 12 is started. The powder solenoid valve 122 at the bottom of the storage hopper 121 controls the flow of material. The material flows into the feeding channel 10 through the feeding pipe 123. The piston rod of the cylinder 111 in the pushing assembly 11 extends and pushes the pushing plate 112 forward along the feeding channel 10, pushing the material in the feeding channel 10 into the mold 6 in the groove 5, thus completing the feeding process.
[0034] After the loading is completed, the cylinder 4 continues to rotate, and the mold 6 loaded with the material is rotated with the cylinder 4 to below the upper opening of the circular baffle 8. At this time, the pressing assembly 9 starts to operate, the hydraulic cylinder 91 drives the pressing block 92 to move downward along the vertical direction, and the pressing block 92 applies uniform and stable pressure to the material in the mold 6, so as to gradually compact and form the loose material into tablets that meet the specification requirements.
[0035] After the tabletting is completed, the mold 6 rotates with the cylinder 4 to the lower opening position of the circular baffle 8. At this time, the tablets are separated from the mold 6 under the action of gravity and fall into the tablet storage box 15 below through the discharging channel 14 at the lower opening.
