Description

Technical Field

[0002] Plastic masterbatch is a concentrate made by attaching an extraordinary amount of plastic additives to resin. When manufacturing plastic products, it is not necessary to add this kind of plastic additives, just add this masterbatch with an extraordinary amount in proportion. Therefore, plastic masterbatch is a new type of special material for polymer material processing. There are many varieties, such as filling masterbatch, color masterbatch, flame retardant masterbatch, antistatic masterbatch, wear-resistant masterbatch, multifunctional masterbatch, etc. In the processing and production of plastic masterbatch, the plastic masterbatch formed by the plastic strips after pelletizing will have a smaller particle size and non-conforming plastic masterbatch due to the cutting of the cutter, and broken plastic fines will appear. These non-conforming plastic particles need to be screened out to ensure the uniformity of the particle size of the plastic masterbatch products.

[0003] After searching, it is found that the typical screening device in the prior art is disclosed in CN217670434U, which is a screening mechanism for the production and processing of plastic masterbatch, including: a conveying block, the top surface of which is fixedly connected with a screening plate, and the top surface of the screening plate is provided with screening holes; a screen, which is movably sleeved inside the screening holes; a cleaning component, which is arranged on the top surface of the screening plate and is used to clean the masterbatch on the screen, and the vibration motor is started to drive the vibration motor to vibrate the masterbatch on the top surface of the screening plate, and at the same time, the masterbatch is moved, so that the screen can screen the masterbatch. At the same time, by setting a driving motor, when the driving shaft of the driving motor drives the rotating rod to rotate, the conveyor belt can rotate inside the rotating groove, thereby driving the moving plate to move on the top surface of the placement block, so that the cleaning block can squeeze and push the masterbatch stuck on the screen in the later stage, effectively avoiding the masterbatch stuck in the screen, thereby accelerating the screening efficiency of the masterbatch in the later stage.
