A pharmaceutical intermediate grinding and crushing device with screening function

Abstract

The utility model relates to the technical field of pharmaceutical equipment, and discloses a pharmaceutical intermediate grinding and crushing device with a screening function, comprising a cushion block, a pretreatment box fixedly installed on the top of the cushion block, a grinding mechanism arranged inside the functional box, and an adjusting mechanism arranged inside the pretreatment box. An intermediate falls between a grinding roller A and a grinding roller B for grinding, and unqualified intermediates rise to the top between the dividing blocks as a screening drum rotates, and fall between the grinding roller A and the grinding roller B under the action of gravity, and are repeatedly ground until all are qualified. A top column repeatedly impacts a mounting plate, driving the screening drum to vibrate slightly, so that qualified intermediates fall, and abnormal use caused by the intermediates being blocked in the hole of the screening drum is avoided. The gap between two arc blocks changes, so that the intermediates fall evenly inside the crushing mechanism for pre-crushing, and also avoid oversized intermediates falling into the crushing mechanism to cause damage to the crushing mechanism, thereby protecting the device.

[0036] Furthermore, the rack 93 is slidably installed inside the pre-treatment box 2, and the slider B94 is slidably installed inside the connecting rod 96, driving the two arc blocks 95 to rotate.

[0037] In actual operation, when the device is used, the fourth motor 91 is started to drive the gear C92 to rotate, and the gear C92 meshes with the two racks 93, so that the rack 93 slides inside the pretreatment box 2 and drives the slider B94 to move inside the connecting rod 96, driving the two arc blocks 95 to rotate, so that the gap between the two arc blocks 95 changes, so that the flow rate can be adjusted at will, so that the intermediate falls evenly into the crushing mechanism 5 for pre-crushing, so that the crushing mechanism 5 crushes more finely and speeds up the speed, which is convenient for subsequent grinding. When a larger intermediate is stuck in the gap, it can be adjusted to take out the intermediate for manual crushing to prevent the oversized intermediate from falling into the crushing mechanism 5 and causing damage to it, thereby protecting the device. The first motor 813 is started to drive the gear A814 and the gear B815, so that the grinding roller A816 and the grinding roller B817 move relative to each other. After pre-crushing, the intermediate enters the screening drum 8110 through the collecting inclined block 6 and the transmission pipe 7, and falls to the grinding roller A816 and the grinding roller B817. The intermediates that have passed the grinding process are ground between the grinding rollers B817, and the second motor 819 drives the screening drum 8110 to rotate. The intermediates that have passed the grinding process fall into the collection drawer 4 through the hole, and the intermediates that have failed the grinding process are between the partition blocks 8111. As the screening drum 8110 rotates, they rise to the top and fall between the grinding rollers A816 and B817 under the action of gravity. The grinding process is repeated until all the intermediates are qualified. The third motor 828 is started to drive the cam 829 to rotate and contact the roller 826, so that the roller 826 drives the protrusion 825 to move, so that the slider A823 slides inside the T-block 821, so that the spring 824 is compressed, and the top column 822 hits the mounting plate 812. The spring 824 makes the slider A823 rebound, so that the top column 822 repeatedly hits the mounting plate 812, driving the screening drum 8110 to vibrate slightly, so that the qualified intermediates fall, avoiding abnormal use caused by clogging in the hole of the screening drum 8110, so that the device can be used continuously.
