Embodiment 1
[0028] Embodiment one: see attached figure 1 to attach Figure 7 shown.
[0029] A rotary cutter for a film crusher, comprising a rotating cutter shaft 1, a plurality of cutter heads 2 that are sequentially fixedly fitted on the rotating cutter shaft 1 and rotate coaxially with the rotating cutter shaft 1, and a moving knife fixedly mounted on the cutter head 2 Component 3.
[0030] Each cutter head 2 is provided with three second key grooves 4 , and the second key grooves 4 are evenly distributed on the inner surface of the cutter head 2 . The outer surface of the rotary knife shaft 1 is provided with a first keyway 5 matching with the second keyway 4, and the first keyway 5 is arranged on the outer surface of the rotary knife shaft 1 in a three-line helical shape along the axial direction of the rotary knife shaft 1 superior. The centerlines of two adjacent first key grooves 5 on each helical line have a second included angle on a plane perpendicular to the axial directi...

The invention relates to a rotary cutter of a film crusher, comprising a rotating cutter spindle, a plurality of cutterheads and a movable cutter assembly. The plurality of cutterheads are sleeved on the rotating cutter spindle; the movable cutter assembly is fixedly mounted in cutter mounting positions on the periphery of the cutterheads; the rotating cutter spindle comprises a first end and a second end; in every two adjacent cutterheads, a cutterhead close to the second end rotates at a first included angle around the rotating cutter spindle relative to a cutterhead close to the first end; the cutter assembly comprises a movable cutter mounting seat, a movable cutter limit block and a movable cutter; the movable cutter limit block is fixedly mounted on the movable cutter mounting seat; the movable cutter is fixedly mounted on the movable cutter mounting seat, attached to the movable cutter limit block and provided with a first inclined plane and an outer plane; a first cutting blade is formed between the first inclined plane and the outer plane and inclines to the axial direction of the rotating cutter spindle; and each first cutting blade of each cutterhead is arranged on the same cylindrical surface. When in use, the rotary cutter of the film crusher has the advantages of high crushing efficiency, small crushing vibration, low noise and stable working current and prevents heat generation.
Description
technical field [0001] The invention relates to a film crusher, in particular to a rotary cutter used in the film crusher. Background technique [0002] With the development of the plastic industry, waste plastic films (agricultural mulch film, agricultural shed film, packaging film, etc.) appear in large quantities and need to be properly recycled. Therefore, different types of film shredders have been developed in the industry. [0003] At present, the structure of the rotary cutter of the common film crusher on the market can be basically divided into several types such as "one-shaped", "V-shaped" or "claw type". The structures of these types of rotary cutters all have common disadvantages: low crushing efficiency, large crushing vibration, loud noise, and large impact of working current. Contents of the invention [0004] The object of the present invention is to provide a rotary cutter of a film crusher with high crushing efficiency, small crushing vibration, low noi...
