Description

Technical Field

[0001] The utility model belongs to the field of machinery, and in particular relates to a cooling and crushing device for a tablet press. Background Art

[0002] The tablet press in the prior art usually uses an ordinary crushing roller, and the roller body is a solid body. For this tablet press structure, especially when the temperature is high in summer, since water cannot be passed through the crushing roller for cooling, and the overall length of the tablet press is short due to the limitation of the plant area, the temperature of the flakes is difficult to be reduced by natural cooling during the crushing process, and can only be cooled by reducing the production volume or adding auxiliary fans. When the production volume increases, the temperature of the flakes is not completely cooled during movement, and the materials are still soft or pressed into a screen shape, which is easy to be entangled on the crushing roller, causing the crushing roller to be bonded to the surface of the roller body by the material, so that the strip-shaped flakes behind cannot move forward, resulting in the front end flakes piling up on the conveyor belt. Moreover, when the fan is used to cool the flakes, the crushing roller cools unevenly, the color is seriously mixed, and the pollution is large, resulting in high production costs, low efficiency, and difficulty in cleaning the machine.
