Description

Technical Field

[0001] The utility model relates to the field of plastic particles, in particular to a cutting and collecting device of a plastic particle extruder. Background Art

[0002] Plastic extruder is a common plastic production equipment that can be used for melt granulation. Its working principle is: the screw rotates in the barrel, the material is continuously pushed and compacted, and under the action of strong shear, friction and external heater, it gradually melts and is extruded from the head at a certain pressure and flow rate. The extruded plastic is cut into plastic particles, and then the plastic particles are collected.

[0003] The Chinese patent with publication number CN217318745U discloses a cutting and collecting device for a recycled plastic pellet extruder, comprising a workbench, a supporting foot is arranged on the lower outer surface of the workbench, a material taking window is opened on the front outer surface of the workbench, a mounting plate is fixedly installed on the upper outer surface of the workbench, an extruder body is arranged on the upper outer surface of the mounting plate, and an automatic rotating cutting device is arranged. After the output shaft of the driving motor rotates, the rotating shaft is driven to rotate. After the rotating shaft rotates in the positioning plate through the mounting bearing, the cutting blade on the handle at the other end of the rotating shaft is driven to rotate. After the cutting blade rotates, the plastic is cut into pellets. However, there are still some shortcomings in the existing device. During the processing, the plastic pellets need to be heated and mixed, and after being cut into pellets, they need to be cooled. The cooling method of the existing device is usually to directly drop the pellets into cold water for cooling, but the pellets sink to the bottom of the water tank and are prone to accumulation and sticking. For this reason, we propose a cutting and collecting device for a plastic pellet extruder to solve the above problems. Utility Model Content
