Description

Technical Field

[0001] The utility model relates to the technical field of engineering plastic masterbatch processing, in particular to a grinding device for the research, development and processing of ultra-light and high-strength modified engineering plastic masterbatch. Background Art

[0002] Plastic masterbatch is a concentrate made by loading an extraordinary amount of plastic additives into resin. It is one of the most important forms of plastic additive application in the world today. Plastic materials can be made into specific shapes through granulators for easy subsequent use. They are usually in the form of masterbatches, so the materials need to be ground and pulverized in advance through grinding equipment.

[0003] In the existing technology, plastic masterbatch production process requires the plastic masterbatch to be crushed and ground. However, the existing plastic masterbatch crushing and grinding equipment lacks screening function when crushing materials. When the material needs to be screened, other screening equipment needs to be used for screening, which reduces the production efficiency.

[0004] The existing patent (publication number: CN212170984U) discloses a crushing and grinding device for plastic masterbatch, which enters between the fixed grinding block and the movable grinding block through a through hole for grinding. Plastic masterbatch larger than the diameter of the through hole continues to be crushed. The rotation of the movable grinding block drives the rotation of the grinding bar, and the rotation of the grinding bar grinds the plastic masterbatch after secondary crushing. The ground plastic masterbatch enters the screening frame. The extension and retraction of the electric telescopic rod drives the screening frame to move back and forth to screen the plastic masterbatch. The crushed and ground plastic masterbatch smaller than the aperture of the screening frame is discharged through the discharge pipe, and the plastic masterbatch larger than the aperture of the screening frame is discharged through the discharge pipe.

[0005] In response to the above problems, although the solution given in the existing patent can crush and grind the material by cooperating with components such as fixed grinding blocks, in actual use, the screen of the equipment is a static design, and the screening efficiency is low, which easily causes the crushed plastic masterbatch to accumulate and form blockage, and larger particles require the screen to be disassembled for cleaning, which is inconvenient to use.
