Special forced feeding mechanism for gunpowder in double discharge tablet press

Abstract

one A special forced feeding mechanism for gunpowder in a double-discharging tablet press, which is composed of a lower hopper connected up and down, a transmission box and a forced feeding impeller box. The transmission box and the impeller box are separated by a pad column, and the surface of the impeller box is provided with a pressure relief ventilation device. Since multiple elongated explosion venting openings are provided at the lower hopper, the explosion venting function is effectively played. According to the particularity of gunpowder material, dust is not allowed to enter the transmission box and cause friction with the bearing. Therefore, the transmission box and the impeller box are separated by the support column, and the separation height is reasonably designed to ensure that the impeller rotation does not fluctuate, which not only ensures the filling accuracy, but also solves the problem of dust entering the transmission box. The upper surface of the impeller box is equipped with a pressure relief ventilation device, which not only plays the role of ventilation to reduce the pressure inside the box, but also has an explosion-proof function, and prevents dust from flying out, thus meeting the requirements for pressing powder tablets.

Description

Technical field [0001] The present invention involves the special forced feeding agency of the gunpowder of the double -out -of -the -ware paddling machine, which can fill the gun material into the various medium -sized holes in the turning table to complete the compulsive feeding function. Background technique [0002] The existing domestic high -speed film machine forced feeding mechanism is composed of feeding buckets, deceleration motor transmission boxes, and compulsive feed impeller boxes. Using the meshing of the gear to convert the unidirectional rotation of the deceleration motor into the reverse rotation of the two dial impeller, use the dial -up dial.The impeller fills the material from the ingredients to the module hole in the turntable. [0003] This structured domestic high -speed chip machine forced feeding mechanisms to complete the material added in the closed environment are only applicable to ordinary materials.Because the transmission box is closed on the impe...

AI Technical Summary

Problems solved by technology

If the material is too fine, the oil seal is damaged and other problems occur, the dust will enter the transmission box through here and cause friction with the bearing, causing the bearing to be damaged

And the inside of the impeller box cannot release pressure, and it is not suitable for special materials such as gunpowder
