A propeller gluing type dipping tank and capsule production line

Abstract

The invention relates to the field of capsule production, and specifically discloses a propeller gluing type dipping tank used in a capsule production line, and a capsule production line with the dipping tank. In the glue dipping tank of the present invention, the glue in the liquid storage tank is injected through the glue hole in the bottom center of the overflow tank through the propeller, and the glue injected through the propeller spirals up, and the glue is sucked by the inclined surface on the blade of the anti-rotation propeller. At this time, the glue entering the overflow tank rushes to the middle of the steady flow device at a faster flow rate and higher pressure. In the length direction of the steady flow tank, the flow rate and pressure are relatively close, so that the liquid level of the glue in the glue chamber is relatively stable. After the capsule mandrel on the same rubber plate is dipped in glue, the capsule on the middle position of the capsule mandrel and the capsule at the edge position are relatively stable. The wall thickness consistency of the capsules on the mandrel is good, and the difference in grain weight is small.

Description

technical field [0001] The invention relates to the field of capsule production, in particular to a propeller-gluing type dipping tank used in a capsule production line, and a capsule production line with the dipping tank. Background technique [0002] The capsule production line usually includes processes such as brushing oil on the capsule mandrel on the rubber plate, dipping in glue, drying, and pulling out the glue. Among them, dipping in glue is a crucial part of the capsule production. It will affect the wall thickness, top thickness, uniformity and particle weight difference of the capsule. [0003] The Chinese utility model patent with the announcement number "CN202105191U" and the Chinese invention patent with the publication number "CN102241097A" disclose a dipping tank for capsule production, which includes an inner tank and an outer tank, the bottom of the inner tank and the bottom of the outer tank Keep a certain interval, there is an opening at the bottom of t...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned dipping tank uses the stirring rod to reciprocate the glue in the inner and outer tanks, under the action of the stirring rod, there is a large difference in flow velocity between the middle of the upper surface of the glue in the inner tank (directly above the stirring rod) and the edge. , the defect caused by this is that after the capsule mandrel on the same rubber board is dipped in glue, the wall thickness of the capsule on the capsule mandrel at the middle position is inconsistent with that on the capsule mandrel at the edge position, and the difference in grain weight is large
