Technical Field

The application relates to the field of branch sieve device, especially relate to a plastic grain divides sieve device.

Background

The plastic is a polymer material widely used, and can be applied to the fields of household appliances, automobiles, mobile phones, PCs, medical instruments and the like, and in the production process, the plastic is usually produced into plastic particles, and then the plastic particles are molded to obtain finished products.

When the plastic particles are produced, the master batch is firstly mixed, extruded into strips after mixing is finished, and then cut into particles, and finally the required plastic particles are obtained. Owing to cut grain in-process, there is the inhomogeneous condition of cutting grain, and partial plastic grain undersize promptly, partial plastic grain is too big, though do not influence follow-up processing, but can make the off-the-shelf quality variation, so cut grain and accomplish the back, can filter the plastic grain, at this in-process, use plastic grain sieving mechanism to sieve the plastic grain usually.

Generally, plastic grain divides sieve device includes the main part, and the main part is provided with vibrating part and screen cloth, and the both ends of main part are provided with feed inlet and discharge gate respectively, and the screen cloth is used for the screening, and vibrating part can drive the main part vibration for the main part carries out the screening of plastic grain at the in-process of shake. In the screening process, the plastic particles are put into the main body from the feeding hole, then screened, and the plastic particles with proper size are discharged from the discharging hole after screened.

However, in the actual production process, the time for putting part of the raw materials into the plastic granules is different in the mixing process, so that the color of the plastic granules may be different, and the screened plastic granules need to be uniformly mixed, so that the plastic granules have good color when leaving the factory. Therefore, the plastic particles can enter the next process after being screened and mixed evenly. However, at present, in the transfer process, the plastic pellets at the discharge port are generally collected in a container and then manually transported to the next process for feeding, but generally, the feed port at the next process is high, so that a forklift is required for feeding, which is troublesome. Therefore, there is a need for a plastic particle sieving device that can facilitate the transportation of plastic particles at the discharge port to the next process.
