Problems solved by technology

Tablet presses currently on the market are usually complex in structure and high in cost, and are not suitable for use in small-scale laboratories and other small-scale preparations of tablets
In addition, the raw materials used for tableting are usually solid powder, so a lot of dust is usually generated during the use of the tableting machine, which does not reduce the cleanliness of the processing operation room, and is easy to cause raw material pollution between different processes

Embodiment 1

[0021] like figure 1 As shown, the tablet press with sweeping function comprises an upper die 1, a middle die 2 and a lower die 3 arranged from top to bottom; the middle die is provided with die holes 4, and the upper die and the lower die are The diameters are equal to the diameter of the die hole; and the upper punch, the die hole and the lower punch are on the same axis; one side of the middle die is provided with a feeding mechanism, and the other side is provided with a powder suction mechanism.

[0022] The upper punch is connected with an upper punch drive mechanism 5 that drives the upper punch to move up and down.

[0023] The lower punch is connected with a lower punch drive mechanism 6 that drives the lower punch to move up and down.

[0024] The powder suction mechanism includes a powder suction nozzle 7, a powder delivery hose 8 and a vacuum cleaner 9. The opening of the powder suction nozzle is arranged on the middle mold, and the other end of the powder suction...

Embodiment 2

[0029] like figure 2 As shown, the difference between the present embodiment and embodiment 1 is that since the compressed material is generally a chemical and pharmaceutical tablet, the compressed raw material is a powder in a powder state. During punching, part of the medicinal powder must overflow, so the medicinal powder is generally pressed and stuck on the upper surface of the lower die 3 during stamping, and if it goes on for a long time, it will have an impact on the later pressing effect. Therefore, it is necessary to carry out bottom hanging treatment on the upper surface of the lower die 3 . Therefore, in this embodiment, a bottom sweeping blade 18 is connected to the side of the feeding box 11 close to the powder suction mechanism. Like this, when the upper surface of the lower die 3 is flush with the upper surface of the middle mold 2, under the promotion of the material box pushing mechanism 13, the feeding box 11 drives the sweeping blade 18 to move toward the...

Abstract

The invention discloses a sheeting machine with a floor sweeping function. The sheeting machine comprises an upper stamping die (1), a middle die (2) and a lower stamping die (3), wherein the upper stamping die (1), the middle die (2) and the lower stamping die (3) are arranged from top to bottom. A die hole (4) is arranged on the middle die, diameter of the upper stamping die and diameter of the lower stamping die are the same as pore size of the die hole, the upper stamping die, the die hole and the lower stamping die are on the same axis, a feeding mechanism is arranged on one side of the middle die, and a powder suction mechanism is arranged on the other side of the middle die. A powder suction nozzle and a dust collector connected with the powder suction nozzle are arranged nearby the middle die. During sheeting operation, dust in an operation room can be removed in time, cleanliness in the operation room is improved, and raw material pollution between different sheeting processes is avoided.

Description

technical field [0001] The invention belongs to the field of pharmaceutical equipment, in particular to a tablet press with a bottom-sweeping function. Background technique [0002] Tablets are one of the most common dosage forms of medicines. Tablets are tablet-shaped preparations that are uniformly mixed with drugs and excipients and compressed. Because the tablet has the following advantages: first, it is more convenient to transport, store, carry, and apply; second, the product has stable properties, accurate dosage, and low cost and selling price. Therefore, the range of tablets is also getting wider. Research on tablet preparation methods and related equipment is also very important. [0003] Currently, tablets are usually made by tablet presses. Existing tablet presses on the market are usually complex in structure and high in cost, and are not suitable for use when preparing tablets in small quantities such as small laboratories. In addition, the raw materials u...
