Vertical plastic additive grinding and screening machine

Abstract

The invention discloses a vertical plastic additive grinding and screening machine. The vertical plastic additive grinding and screening machine is characterized in that a partition plate and screensare arranged in a cylinder body, the partition plate is fixedly connected with the inner wall of the cylinder body, and the screens are horizontally arranged below the partition plate; a rotating shaft is arranged in the cylinder body, the upper end of the rotating shaft is rotationally connected with the top of the cylinder body, and the lower end of the rotating shaft is correspondingly connected with the partition plate and the screens in a rotating mode; a grinding plate is fixedly arranged on the rotating shaft, and the grinding plate is arranged between the partition plate and the screens; a first grinding surface is arranged on the lower surface of the partition plate, a second grinding surface is arranged on the upper surface of the grinding plate, and a gap is formed between the first grinding surface and the second grinding surface; material guide holes are formed in the partition plate, and the bottoms of the material guide holes communicate with the gap; and transverse rodsare fixedly arranged on the rotating shaft and located above the screens, brush bristles are arranged on the transverse rods, and the bottoms of the brush bristles are attached to the screens. According to the vertical plastic additive grinding and screening machine, the ground plastic additive powder enters the screens and moves on the screens through the brush bristles, so that the powder on the screens is leveled and scattered, and the screening effect is improved; and meanwhile, the integral structure is sealed, so that dust is effectively prevented from entering the machine.

Description

technical field [0001] The invention relates to the field of production and processing equipment for plastic additives, in particular to a vertical grinding and screening machine for plastic additives. Background technique [0002] Plastic additives, also known as plastic additives, are compounds that must be added to improve or enhance the performance of plastic products during the production and processing of plastic products. [0003] Generally, the ground plastic additive powder must be sieved to screen out powders of different finenesses to meet the needs of actual production and processing. When sieves are used for sieving, because the powder is easy to concentrate and accumulate on the sieve, the sieve is easy to block, and the screening effect is not good. Contents of the invention [0004] In view of the above-mentioned technical problems, the object of the present invention is to propose a vertical grinding and screening machine for plastic additives, which inte...
