Embodiment 1

[0034] Such as figure 1 , 2 As shown, an intermittent quantitative blanking device includes a sheet metal silo module, a quantitative blanking control mechanism 4, and a blanking tube 5. The sheet metal silo module includes a transition cone storage bin 2 and is connected to a transition cone The blanking bin 3 at the lower part of the storage bin 2 is connected to one end of the quantitative blanking control mechanism 4 in the blanking bin 3, and the lower part of the blanking bin 3 is connected to the feeding pipe 5 through a docking piece 11, and a feeding pipe 5 is arranged outside the feeding pipe 5. The level sensor 6 , specifically the material level sensor 6 is arranged at the lower part of the feeding pipe 5 . Wherein, the upper part of the transitional conical storage bin 2 is connected to the feeding mechanism through the flange plate 1, and the lower end of the feeding pipe 5 is connected to the equipment feeder through the docking port 7. In the figure, componen...

Embodiment 2

[0043] The present invention also provides a control method of an intermittent quantitative blanking device, comprising:

[0044] When the material is lower than the position of the material level sensor 6, the PLC controller of the intelligent control module controls the solenoid valve to issue an action command, the solenoid valve opens, the double-axis cylinder 41 moves, and the cylinder drive shaft 42 drives the connecting shaft 46 to reciprocate to realize alternate filling, Blanking work, specifically:

[0045] When the cylinder transmission shaft 42 is stretching out, the second gap 48 between the two pusher plates 49 away from the connecting block 44 is separated from the blocking plate 43 to start the discharge work, and the two pusher plates 49 close to the connecting block 44 The first gap 47 and the blocking plate 43 form the quantitative storage bin 9 and start the filling work;

[0046] When the cylinder transmission shaft 42 is retracted, the first gap 47 betwe...

Abstract

The invention discloses an intermittent quantitative blanking device and a control method thereof. The intermittent quantitative blanking device comprises a metal plate bin module, a quantitative blanking control mechanism and a blanking pipe, the metal plate bin module comprises a transition conical storage bin and a blanking bin connected to the lower portion of the transition conical storage bin, and the blanking pipe is installed on the lower portion of the blanking bin; and the inside of the blanking bin is connected with one end of the quantitative blanking control mechanism, a material level sensor is further arranged on the outer side of the blanking pipe, the material level sensor is electrically connected with an intelligent control module, and the intelligent control module is electrically connected with the quantitative blanking control mechanism. Quantitative alternate filling and blanking work is controlled through the quantitative blanking control mechanism, the amount of materials is proper, and the extrusion condition does not exist. When the material level is lower than a control material level reference line every time, a material level sensing signal is output to automatically control to complete each blanking action and supplement the material level, the influence of the filling speed is avoided, quantitative materials are ensured to be supplied to a feeder, and the consistency of parameters such as the material consumption, the density and the fluidity is realized.

Description

technical field [0001] The present application relates to the technical field of pharmaceutical machinery and equipment, in particular to an intermittent quantitative feeding device and a control method thereof. Background technique [0002] Medium and large high-speed rotary tablet presses are mainly used in the pharmaceutical industry to process tablets, to press granular or powdery media into round, special-shaped or tablets with text, symbols or graphics, and are suitable for batch production. Key equipment for production. The tablet press workflow includes feeding, quantitative filling, pre-compression, main compression and tablet discharge. In recent years, the demand for the promotion and application of high-speed tablet presses has shown a stable state, and the performance and quality requirements of high-speed tablet presses have become higher and higher. Hardness), tablet dimensions (height dimension and radial dimension) requirements, but also a high degree of a...
