Cutter of plastic crusher and plastic crusher

Technical Field

The utility model relates to a plastics rubbing crusher's reducing mechanism's cutter and adopt the plastics rubbing crusher of this kind of cutter, more specifically say and relate to a rational in infrastructure, be difficult to the cutter of the plastics rubbing crusher who damages and adopt the plastics rubbing crusher of this kind of cutter.

Background

The crushing knife of the plastic crusher is a rotating shaft which drives the linear blade to rotate so as to cut plastic articles, so that the linear blade is an important structure. The parallel wide structure of the linear blade is suitable for crushing large-volume thin-wall and thin-material products.

The cutter of the plastic crusher, disclosed in the chinese patent document with the publication number CN208410398U, and the name "V-shaped blade structure of the plastic crusher", comprises a rotating shaft, wherein two baffles are symmetrically arranged on the rotating shaft, four blade group installation seats are arranged between the two symmetrically arranged baffles, two blade groups are detachably installed on the four blade group installation seats, and an outer splayed structure is formed between two adjacent blade groups. The blade group comprises a first blade and a second blade, two second fixing holes are formed in the blade group, the two second fixing holes are not located on the same horizontal height, and the two second fixing holes respectively penetrate through the first blade and the second blade.
