[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 kinds and subdivided into thousands of kinds. Common plastic particles include general plastics, engineering plastics, and special plastics.
[0003] In order to realize the transportation of plastic particles, the Chinese patent "Modified Plastic Particle Production Line" (patent number: 201410071119.8) improves the environment of the workshop and protects human health by setting a dust cover and a smoke cover outside the extruder heating unit. The Chinese patent discloses a feeding device for the production and processing of plastic particles (authorization announcement number CN217098826U). The patent technology discloses a feeding device for the production and processing of plastic particles, including a bottom plate, the top of the bottom plate is fixedly connected with a first support column and a second support column by bolts, the first support column is located on one side of the second support column, and the tops of the first support column and the second support column are fixedly connected with a feeding box by bolts, the top of the feeding box is fixedly connected with a storage barrel by bolts, and a first motor is fixedly connected with a first motor on one side of the outer wall of the feeding box by bolts, and a guide platform is arranged on one side of the inner wall of the feeding box. The feeding equipment for the production and processing of plastic particles can realize the conveying and weighing of the raw materials for plastic particle processing through the cooperation of the storage cylinder, the feeding tube and the metering cylinder, so as to ensure the accuracy of the raw material mixing ratio, and then ensure the quality of the processed plastic particles, and avoid the problem of inaccurate feeding caused by the idle rotation of the screw caused by the traditional screw conveying to achieve quantitative feeding through the rotation speed. This patented technology solves the problem that the stirring feeder in the plastic particle production line can only realize the stirring and mixing feeding of the plastic particle raw materials, and cannot accurately measure and proportion the plastic proportion raw materials, thereby causing the low quality of subsequent plastic particle processing.
