[0002] With the continuous advancement of pharmaceutical technology and the diversification of people's demands for drug dosage forms, chewable tablets, as a convenient, quick, and easily accepted dosage form, have gradually gained popularity. From the initial simple calcium and vitamin chewable tablets to today's chewable tablets covering a variety of drug types, their variety and application scope have been continuously expanding. The main process in the production of chewable tablets is the use of tablet presses for molding. There are various types of tablet presses available, and they are modified according to different needs to meet the tableting requirements of different chewable tablets. Although existing rotary tablet presses have a fast tableting speed, the parts that cooperate with the track wear out quickly, while traditional tablet presses have a slower tableting speed, mainly because they are not suitable for batch processing.

The tablet pressing mechanism 2 and the feeding mechanism 3 are mounted on the fixed frame 1. The loading mechanism 4 is mounted on the feeding mechanism 3 and is connected to the power unit via a transmission connection. The power unit is mounted on the fixed frame 1. The loading mechanism 4 includes a fixed column 41, a shifting column 42, a shaking column 43, a shifting plate 45, a shaking circular plate 46, and a shaking bucket 47. One end of the shifting column 42 passes through the fixed column 41 and is connected to the shifting plate 45. One end of the shaking column 43 passes through the shifting column 42 and the shifting plate 45 and is connected to the shaking circular plate 46. The shifting column 42 and the shaking column 43 are located away from each other. One end of each vibrating circular plate 46 is connected to a helical gear 44. Several vibrating buckets 47 are mounted on a shifting plate 45 and their discharge ends cooperate with the tableting mechanism 2. A feeding slant plate is connected to the side of the vibrating bucket 47 near the discharge end of the tableting mechanism 2. The circumference of the vibrating circular plate 46 is wavy and cooperates with the vibrating buckets 47. The tableting mechanism 2 includes a tableting lifting plate 21, a tableting template 22, a tableting cylinder 23, and a stamping column 24. At least two tableting cylinders 23 are mounted on the tableting lifting plate 21 and their piston rods are connected to the fixed frame 1. The tableting template 22 is connected to the fixed frame 1. One end of several stamping columns 24 is connected to the tableting lifting plate 21 and the other end passes through the tableting template 22. The feeding mechanism 3 includes a feeding cylinder 31, a feeding lifting plate 32, lifting columns 33, a material plate 34, guide pressure columns 35, and a positioning plate 36. The feeding cylinder 31 is mounted on the feeding lifting plate 32, and its piston rod is connected to the fixed frame 1. One end of each of the lifting columns 33 is connected to the feeding lifting plate 32, and the other end is connected to the material plate 34 through the pressing template 22. The material plate 34 is slidably connected to the fixed column 41. The positioning plate 36 is connected to the pressing template 22 through the fixed column 41. One end of each of the guide pressure columns 35 is connected to the positioning plate 36. The material plate 34 has several pressing holes 37 for the guide pressure columns 35 to pass through, and the pressing holes 37 are arranged around the fixed column 41. A feeding avoidance groove 38 is provided on the material plate 34 between adjacent pressing holes 37 to cooperate with the shaking bucket 47; each shaking bucket 47 includes a slide 48, a bearing 49, a hopper 410 and a return spring 411. The slide 48 is slidably connected to the shaking circular plate 46. The bearing 49 is connected to the slide 48 and cooperates with the circumferential surface of the shaking circular plate 46. The hopper 410 is connected to the slide 48 and its outlet is in contact with the upper surface of the tablet pressing template 22. One end of the return spring 411 is connected to the shaking circular plate 46 and the other end is connected to the slide 48. The end of the hopper 410 near the tablet pressing template 22 is inclined to avoid the material plate 34. A silicone layer is sintered on the outlet of the hopper 410.

[0020] The power unit consists of two motors and two helical gears. The motors drive the helical gears to rotate, which in turn drive the corresponding helical gears 44 to rotate. For ease of understanding, the hole on the tableting template 22 through which the punching column 24 passes is referred to as the drug measurement hole. The feeding cylinder 31 drives the feeding lifting plate 32 to rise and fall, which in turn drives the lifting column 33 to rise and fall, which in turn drives the material plate 34 to rise and fall, so that the material plate 34 is in close contact with the tableting template 22. The tableting cylinder 23 drives the tableting lifting plate 21 to rise and fall, which in turn drives the punching column 24 to rise and fall. When the punching column 24 rises, it pushes the drug powder in the drug measurement hole into the pressing hole 37. At the same time, the punching column 24 and the guide pressing column 35 work together to compress the drug powder into chewable tablets. After the chewable tablets are formed, they are in the pressing hole 37. When the material plate 34 rises, it will cause the chewable tablets in the pressing hole 37 to be ejected. Then, the shaking bucket 47 is shaken. The feeding sloping plate pushes the chewable tablets out and into the material box; the power unit drives the helical gear 44 to rotate, the helical gear 44 drives the shifting column 42 to rotate, the shifting column 42 drives the shifting plate 45 to rotate at a certain angle, so that the discharge port of the hopper 410 of the shaking hopper 47 on the shifting plate 45 covers the dosage hole; at the same time, the power unit drives another helical gear 44 to rotate, the helical gear 44 drives the shaking column 43 to rotate, the shaking column 43 drives the shaking circular plate 46 to rotate, and the wave-like shape of the circumference of the shaking circular plate 46 drives the bearing 49, the bearing 49 drives the slide 48 to move back and forth, so that the hopper 410 moves back and forth synchronously, so that the material in it enters the dosage hole; after the hopper 410 fills the dosage hole, it moves to the feeding avoidance groove 38 area to prevent the material plate 34 from falling and colliding with the hopper 410; the silicone layer prevents the hopper 410 from directly rubbing against the tableting template 22.
