Description

Technical Field

[0001] The utility model relates to the technical field of roller brushes, in particular to a roller brush mechanism and a pill making machine. Background Art

[0002] Currently, there are two types of roller brush devices for pill making machines: one is able to rotate actively, and is driven by the gear in the transmission box of the pill making machine to drive the pill making knife wheel to move, and the direction of rotation is the same as that of the pill making knife wheel; the other roller brush cannot rotate actively, and is driven by the rotation of the pill making knife wheel, and the direction of the roller brush is opposite to that of the pill making knife wheel.

[0003] In the actively rotating roller brush device, the roller brush is driven to rotate by the gear pair in the transmission case. The distance between the roller brush and the pill-making cutter wheel cannot be adjusted. When the roller brush is worn, it can only be replaced with a new roller brush. Therefore, the roller brush device needs to replace the roller brush frequently, which increases production costs. In the non-active roller brush device, the roller brush rotates passively in the opposite direction to the pill-making cutter wheel, making it difficult to brush off all the pills stuck on the pill-making cutter. Instead, the pills are easily "bitten" into the pill-making cutter wheel again, affecting subsequent pill-making. In addition, the roller brush devices of both structures require the additional addition of a large amount of alcohol to prevent the pills from sticking to the cutter wheel. Because alcohol is volatile, flammable, and explosive, when the alcohol volatile concentration in the workshop reaches a certain level, it is prone to danger, increasing safety hazards in the production workshop. Meanwhile, a large amount of alcohol input increases costs. Utility Model Content
