Description

Technical Field

[0001] The utility model relates to the technical field of material dividing and feeding structures, in particular to a material dividing and feeding device for a plastic extrusion granulator. Background Art

[0002] Plastic granulation is a process of plastic mechanical processing. Plastics of various forms are prepared into uniform granules that are convenient for subsequent processing through processes such as melting, extrusion, and granulation. In the plastic granulation production line, more and more granulation feeding mechanisms are used in the production line. Feeding equipment is an auxiliary equipment in the mechanized storage and transportation system of granulation production enterprises. Its main function is to feed processed or unprocessed materials from a certain equipment (hopper, storage bin, etc.) to the receiving equipment or transportation machinery continuously and evenly. However, although the existing plastic granulation feeder can increase production output, the ordinary plastic granulation feeding mechanism often encounters feeding technology bottlenecks in the granulation production process, including low feeding efficiency and low feeding automation. However, the existing granulation feeder still has certain problems when in use:

[0003] For example, a PVC granulation feeding mechanism with publication number CN208730057U has the following technical solution: it includes a feed hopper and a motor, cross frames are symmetrically installed on both sides of the motor, a movable groove is provided inside the cross frame, a movable block is installed on the outer side of the movable groove, a slide groove is provided inside the cross frame, sliders are installed on both sides of the movable block, the sliders are installed in the slide groove, an outer splint is installed on the left side of the bottom of the movable block, an inner splint is installed on the right side of the bottom of the movable block, the inner splint is placed on the inner wall of the feed hopper, and bolts are passed horizontally through the outer splint. The utility model clamps the two sides of the feed hopper by inner and outer clamps, and then rotates in the outer clamp by bolts, thereby driving the clamp to move rightward, so that the right end of the clamp is meshed with the outer wall of the feed hopper, and the inner and outer clamps can be fixed to the feed hopper through the meshing. However, the existing granulating feeding mechanism cannot separate materials during the feeding process, and the screening of raw materials causes large particles of raw materials to block the feed pipe. The feeding speed is too fast, so that the small particles of raw materials cannot be screened for secondary processing.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0005] In view of the above problems, an innovative design is carried out based on the original granulation feeding mechanism. Utility Model Content
