Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to an anti-splashing pelletizing device for plastic pellet production. Background Art

[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic particles include general plastics, engineering plastics, and special plastics. General plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate silicone, etc. When the cut plastic particles are output from the discharge end, splashing will occur, which is not only inconvenient for the collection of plastic particles, but also easy to pollute the surrounding environment.

[0003] After searching, a Chinese patent with publication number CN216884734U discloses an anti-splashing pelletizing device for plastic pellet production, including a plastic pellet forming device, a first cooling bin is fixedly installed on one side of the plastic pellet forming device, a rotating connecting shaft is connected in the first cooling bin, a main gear is fixedly connected to the rotating connecting shaft, a fixed connecting shaft is fixedly connected in the first cooling bin, a driven gear is rotatably connected to the position of the fixed connecting shaft corresponding to the main gear, the driven gear is meshed with the main gear, an upper connecting piece is rotatably connected to the driven gear, the lower end of the upper connecting piece is rotatably connected to the lower connecting piece, the lower end of the lower connecting piece is rotatably connected to a movable screen plate, an inclined baffle is installed in the first cooling bin, and the lower end of the inclined baffle is slidably connected to the movable screen plate.

[0004] The device drives the cutting blade to cut by rotating the connecting shaft, and at the same time drives the main gear to rotate, so that the driven gear rotates and drives the movable screen plate to move to screen the plastic particles.

[0005] However, the device still has the following problems: the device drives the rotating connecting shaft to rotate through the first motor, and then drives the cutting blade to rotate through the rotating connecting shaft, so as to facilitate the cutting of the plastic strips output at the discharge end. In actual use, the first electrode drives the rotating connecting shaft and the cutting blade to rotate in a relatively single direction. When the cutting blade in a single cutting direction contacts the plastic strip, the plastic strip is prone to partial deformation and partial breakage, which makes it difficult to effectively improve the pelletizing efficiency of the device.
