Description

Technical Field

[0001] The utility model relates to the field of granulators, in particular to an anti-adhesion cutting device of a plastic granulator. Background Art

[0002] The existing cutting device cannot adjust the cutting angle of the blade. During the production process, materials of different properties may have different performances during the cutting process. When the properties of the materials change, the original cutting angle is no longer applicable and needs to be adjusted accordingly. Generally, the cutting knives are fixedly mounted on the knife seat, and the cutting angle is fixed. If the cutting angle needs to be adjusted, the knife seat with the corresponding angle needs to be replaced, which is very troublesome and increases the production cost, reduces the applicability and practicality, and is not convenient for replacing the blade. Generally, the blade is fixed to the knife seat by bolts. When replacing the blade, tools are needed to disassemble and assemble the bolts. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the work efficiency. In order to solve the above-mentioned problems, we propose an anti-adhesion cutting device for a plastic granulator. Utility Model Content
