Vertical plastic assistant screening machine

Abstract

The invention discloses a vertical plastic assistant screening machine. A screening box is arranged on a bracket through a spring; a vibrating motor is arranged in the bottom of the screening box; a feeding box is arranged above the screening box; a quantitative feeding device is arranged in the feeding box; collecting tanks are arranged in a spaced manner from top to bottom in the screening box;a discharge pipe is arranged in the bottom of each collecting tank; transverse shafts are separately arranged on the left and right sides of the collecting tanks; two ends of the transverse shafts arerotatably connected to the screening box; penetrating semi-circular slide grooves are formed in the side face of the screening box centered by the centers of the corresponding transverse shafts; thedischarge pipe extends outward and penetrates through the slide groove to reciprocate in the slide groove; horizontal screens are correspondingly arranged in the collecting tanks; and the pore diameters of the screens are successively increased from top to bottom. As the pore diameters of the screens are successively increased from top to bottom, the plastic assistant with the minimum particle canbe screened for the first time, so that the screening speed is improved; meanwhile, by arranging the quantitative feeding device, accumulation of the plastic assistant on the screens is reduced, so that the screens are prevented from being blocked.

Description

technical field [0001] The invention relates to the field of plastic auxiliary agent production and processing equipment, in particular to a vertical plastic auxiliary agent screening machine. Background technique [0002] In the production and processing of plastic products, different processes require plastic additives with different particle diameters, so it is necessary to screen plastic additives. Most of the current screening methods are to put the plastic additives into the screening equipment as a whole, and then perform stirring or vibration screening. This screening method is likely to cause the concentrated accumulation of materials on the screen, which is easy to block and the screening effect is not good. Secondly, the aperture of the screen mesh used in the current screening method decreases sequentially from top to bottom; this screening method requires multiple reciprocating screening to screen out plastic additives with different particle diameters, and the ...
