Description

Technical Field

[0001] The utility model relates to the technical field of pelletizing equipment, and more specifically, to a pelletizing device for processing polyethylene pellets. Background Art

[0002] Polyethylene is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. It is made by the polymerization of ethylene and is divided into high-density polyethylene, medium-density polyethylene and low-density polyethylene according to different densities. During the processing of polyethylene, it is necessary to use an extrusion device to make polyethylene into granules.

[0003] In the process of polyethylene pelletizing, polyethylene is usually stored in a tank, and the polyethylene is pushed out through a hole-shaped mold by an internal hydraulic cylinder. The extruded long cylindrical polyethylene is cut into pellets by a reciprocating cutter on the top. Since polyethylene is continuously extruded from multiple holes, the cutter reciprocates from top to bottom, and the cutter first passes through the top circular hole and then the bottom circular hole, which will cause the cut pellets to be uneven in size and affect the molding quality of the polyethylene pellets.

[0030] A specific application of this embodiment is: the second pellet extrusion hole 83 is always kept opposite to and close to the first pellet extrusion hole 73 by the anti-slip mechanism 6, and the polyethylene enters the second pellet extrusion hole 83 after passing through the first pellet extrusion hole 73, and the motor 810 drives the rotating shaft 811 to rotate, and the rotating shaft 811 drives the missing gear 812 to rotate, and the missing gear 812 drives the driving gear 84 to rotate, and the driving gear 84 drives the matching barrel 82 to rotate intermittently, and the matching barrel 82 rotates a fixed angle each time.
