The utility model discloses a control roll moment and obtain the sheet of different density, utilize the operation of the unified control feed part of motion controller of control roll, pay-off part and rotating valve part simultaneously, make sheet density even in succession, solved the unstable international technological problem of quality that dry process granulator production changes the medicine granule and appears.
Description
Technical Field
The utility model relates to a pharmaceutical machinery technical field, concretely relates to feed mechanism of dry process granulator.
Background
The dry granulating machine is used for producing granular products, and aims to compress powder with different flowability into qualified granular finished products with specified sizes. The structure of the feeding mechanism of the dry-method granulator is as follows: the dry granulating machine comprises a charging bucket and a feeding part, wherein the charging bucket is arranged in the feeding part, the feeding part comprises a feeding motor and a screw, during operation, vacuum is formed in the charging bucket to suck powder in a powder storage bucket, and then the screw is driven by the rotation of the feeding motor to extrude the powder in the charging bucket into a feeding mechanism of a dry granulating machine. However, the feeding mechanisms of the dry granulating machine adopting the mechanism and other prior art have the problems of powder blockage and uneven feeding in the feeding process in different degrees, especially for the powder with large viscosity, and the feeding effect is not good.
Disclosure of Invention
In view of the defects of the prior art, the present invention aims to provide a feeding mechanism of a dry granulating machine, which can obtain sheets with different densities by controlling the moment of a roller, and simultaneously uniformly control the operations of a feeding part, a feeding part and a rotating valve part by using a motion controller, so as to make the density of the sheets continuously uniform.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to accomplish:
the dry method granulator feed mechanism comprises a feeding part, a feeding part and a rotating valve part, wherein a valve body of the rotating valve part is provided with an upper opening connected with an outlet at the bottom of a material barrel, a lower opening connected with an inlet of a feeding material barrel of the feeding part, the feeding material barrel is obliquely installed at the right side, an outlet of the feeding material barrel is connected with an inlet of the feeding material barrel of the feeding part, the feeding material barrel is obliquely installed at the left side, an outlet of the feeding material barrel is provided with an upper roller and a lower roller, a feeding screw rod of the feeding part is driven by a first servo motor, a feeding screw rod of the feeding part is driven by a second servo motor, and a rotating blade of the rotating valve part is driven by: the upper roller is driven by a fourth servo motor, the lower roller is driven by a fifth servo motor, and the first servo motor, the second servo motor, the third servo motor, the fourth servo motor and the fifth servo motor are controlled by a motion controller in a unified mode.
In the feeding mechanism of the dry granulating machine in the technical scheme, when the feeding mechanism works, medicinal powder is discharged from the material barrel, then the medicinal powder is fed into the feeding material barrel through the rotation of the rotating blade, then the feeding screw rod rotates to feed the medicinal powder into the feeding material barrel, then the feeding screw rod rotates to feed the medicinal powder out of the feeding material barrel, and finally the medicinal powder is pressed into a sheet with certain density by the upper roller and the lower roller; in the working process, the motion controller can obtain the sheets with different densities by controlling the torque of the upper roller and the lower roller, and simultaneously the motion controller uniformly controls the rotating speeds of the rotating blades, the feeding screw and the feeding screw, so that the feeding of the powdered medicine meets the production requirements of the sheets with different densities, the motion controller enables the actions of all related parts to quickly respond, the density of the sheets extruded by the rollers is unchanged, and the sheets are continuous and uniform, and further the international technical problem of unstable quality in the production of ever-changing medicine particles by a dry granulating machine is solved. In addition, as the upper roller and the lower roller are driven by different servo motors, the center distance can be quickly adjusted to adapt to the production of sheets with different thicknesses.
Preferably, three rotating blades of the rotating valve part are uniformly distributed on the circumference.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
