By adopting the structure, the tablet can be pressed into a porous tablet by utilizing the occupying column positioned in the forming cavity, thereby increasing the contact area between the tablet and liquid and being beneficial to improving the disintegration degree of the tablet.

Description

Tabletting device

Technical Field

The utility model provides a tabletting device.

Background

Tablets are usually made by compression molding, and are usually compressed into a tablet form, which is relatively unitary. Such a form of tablet greatly affects the disintegration of the tablet, resulting in sufficient consideration in the compounding, compression, and the like.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model aims to provide a novel tabletting device.

In order to achieve the purpose, the tabletting device comprises a cylindrical cavity, wherein more than two occupation columns are upwards arranged at the bottom in the cavity, and each occupation column is parallel to the axis of the cavity; the height of the occupying column is equivalent to that of the cavity;

a piston is further arranged in the cavity, a through hole is formed in the piston corresponding to each occupying column, and the diameter of each through hole is matched with that of each occupying column;

the pushing device is connected with the piston and is used for pushing the piston to move up and down in the cavity; and

the diameter of the upper pressing die is matched with the inner diameter of the cavity, and the upper pressing die and the cavity are coaxially arranged;

and the upper pressing die driving device drives the upper pressing die to reciprocate towards the cavity.

Preferably, the upper pressing die is provided with a hole at a position corresponding to the position occupying column.

Preferably, the ejector rod holes are distributed at the vacant positions between the adjacent occupying columns at the bottom of the cavity; the ejector rod hole is internally provided with an ejector rod in a penetrating way; one end of the ejector rod, which is positioned in the cavity, is connected to the lower end surface of the piston; and one end of the ejector rod, which is positioned outside the piston, is connected with the pushing device.

By adopting the structure, the tablet can be pressed into a porous tablet by utilizing the occupying column positioned in the forming cavity, thereby increasing the contact area between the tablet and liquid and being beneficial to improving the disintegration degree of the tablet.

Detailed Description

The invention will be further described with reference to the accompanying drawings and examples

Example 1

Fig. 1 shows a tabletting device of the present invention, which comprises a cylindrical cavity 1, wherein more than two occupying columns 2 are arranged upwards at the bottom in the cavity, and each occupying column is parallel to the axis of the cavity; the height of the occupying column is equivalent to that of the cavity;

a piston 3 is further arranged in the cavity, a through hole 31 is formed in the piston corresponding to each occupying column, and the diameter of each through hole is matched with that of each occupying column;

the pushing device 4 is connected with the piston and is used for pushing the piston to move up and down in the cavity; and

Preferably, the upper die is provided with holes 51 corresponding to the position of the occupation column.

The ejector rod holes 6 are distributed at the vacant positions between the adjacent occupied columns at the bottom of the cavity; the ejector rod hole is internally provided with an ejector rod 7 in a penetrating way; one end of the ejector rod, which is positioned in the cavity, is connected to the lower end surface of the piston; and one end of the ejector rod, which is positioned outside the piston, is connected with the pushing device. Wherein, the quantity of ejector pin can design as required, can be one, also can be many.

Example 2

Fig. 15 and 16 show another embodiment of the present invention, which is a modification of embodiment 1. As can be seen from the figure, one side (or more sides) of the piston 3 is connected with a transverse mandril 7, and the up-and-down motion of the piston is realized by connecting the transverse mandril with a reciprocating pushing device.

According to the above embodiments, the present invention is directed to a novel tabletting device for pressing porous tablets. The cross-sectional shape of the cavity can be designed according to the requirement, for example, the cross-sectional shape can be designed to be circular, quadrilateral or hexagonal; likewise, the cross-sectional shape of the placeholder column may be designed as circular or polygonal as desired. The pushing device can be selected by those skilled in the art as a pneumatic cylinder, a hydraulic cylinder, or an electric push rod or other mechanical reciprocating mechanism according to the requirement, and will not be described herein.
