Embodiment 1

[0031] like figure 1 As shown, the anti-fragmentation tablet press includes a frame 1, on which an upper die 4, a middle die 2 and a lower die 6 are arranged from top to bottom, and the upper die 4 is connected to drive the upper die 4 to move up and down The upper drive mechanism 5, the lower punch 6 is connected with the lower drive mechanism 7 that drives the lower punch 6 to move up and down, the middle die 2 is provided with a die hole 3, the die head of the upper die 4 and the die head of the lower die 6 are all connected to the die hole 3, and the axes of the upper die 4, the lower die 6 and the die hole 3 are coincident; the right side of the frame 1 is provided with a feeding hopper 8, and the upper part of the frame 1 is also provided with an upper drive mechanism 5 to control the upper Time relay 12 for the dwell time when the die 4 is pressed down onto the tablet.

Embodiment 2

[0039] like figure 1 As shown, similar to embodiment 1, the difference is:

[0040] Also be provided with recovery tank 13 between charging box 9 and middle mold 2, recovery tank 13 comprises tank body and connecting rod, the central axis of the tank body of recovery tank 13 coincides with the central axis of charging hole, the bottom surface of tank body and middle mold The upper end faces of 2 are located on the same horizontal plane. The area of ​​the tank body of the recovery tank 13 should be larger than that of the feeding hole. This is because there is a gap between the feeding hole and the feeding box 9, and the powder is easy to leak from the gap, resulting in waste of raw materials. The setting of the recovery tank 13 can prevent powder leakage. , to reduce waste.

[0041] The connecting rod of the recovery tank 13 is connected with the box pushing mechanism 11, and the middle mold 2 is positioned on the right side of the die hole 3 and is also provided with a limi...

Abstract

The invention discloses a tabletting machine capable of preventing fragmentation. The machine comprises a machine frame, wherein an upper stamping die, a middle die and a lower stamping die are arranged on the machine frame from top to bottom, the upper stamping die is connected with an upper driving mechanism for driving the upper stamping die to move up and down, the lower stamping die is connected with a lower driving mechanism for driving the lower stamping die to mode up and down, and a die hole is formed in the middle die; a die head of the upper stamping die and a die head of the lower stamping die are both matched with the hole diameter of the die hole; the axes of the upper stamping die, the lower stamping die and the die hole coincide; a feed hopper is arranged on the right side of the machine frame; a time relay which is connected with the upper driving mechanism to control stay time when the upper stamping die is downwards pressed on a tablet is also arranged above the machine frame. The tabletting machine is simple in structure and convenient to operate, can increase the rate of finished tablet products, improve the production efficiency, can also reduce generated dust, and can reduce a mixing rate of impurities in the tablet in a manufacturing process.

Description

technical field [0001] The invention relates to the field of pharmaceutical machinery, in particular to an anti-fragmentation tablet press. Background technique [0002] At present, tablets are one of the most common dosage forms of medicines. In actual production, tablet machines are often used to compress medicines or other raw materials. The tablet often falls off after being pushed out in the die hole. The falling off refers to the slivers. The reasons for the slivers are as follows: [0003] 1. There is air in the particles; [0004] 2. The compression speed is also faster; [0005] 3. The pressure is relatively high; [0006] 4. The particles are too dry; [0007] 5. Improper compression behavior of particles; [0008] 6. Uneven pressure; [0009] Tablet fragmentation will have a great impact on productivity and production cost. How to solve the problem of tablet fragmentation has become one of the focuses of tablet compression. Aiming at the problem that tablet...
