Description

Technical Field

[0001] The utility model relates to the technical field of PVC particle screening, in particular to a material shaking screening structure of a PVC particle screening machine. Background Art

[0002] PVC plastic particles are a kind of soft plastic particles. Due to its soft characteristics, it is often used to be processed into transparent tape. In addition, adding some additives to itself can increase its hardness. Another type is PVC injection molding particles, which can be roughly divided into gray, yellow and red. It has very good corrosion resistance, weather resistance, stability, and non-flammability. It is very durable when made into various products. Therefore, it is one of the most popular products on the market.

[0003] Compared with the shaking screening structure of the PVC particle screening machine of CN211054184U, by driving the rotation of the motor and through mechanical transmission, the two groups of screening frames can screen the PVC plastic particles by shaking up and down under the limiting action of the limiting card plate, thereby reducing the clogging of PVC particles on the screening filter plate and the impact on the production efficiency of PVC plastic products due to clogging. At the same time, the design of the upper and lower layered screening filter plates can filter out PVC particles in layers to obtain PVC particle products with different pore sizes. Of course, it is not necessary to achieve all the advantages mentioned above at the same time for any product implementing the utility model.

[0004] At present, most PVC particle screening machines on the market have a material shaking screening structure. When screening PVC particles, there is no shaking screening mechanism, which causes the screening effect of the PVC particle screening machine to be poor, thus affecting the screening effect of the PVC particle screening machine.
