Abstract
Claims
1. Cutting device for renewable recycled infill, comprising a frame, characterized in that The top left and right ends of the frame are fixedly connected to connecting frames, and multiple connecting rods are evenly distributed between the two connecting frames. One end of each connecting rod is movably connected to a clamp, and the bottom of each clamp is connected to the same limiting baffle. The front side of the frame is fixedly connected to a cutting mechanism, and the rear side of the frame is connected to an expansion cutting mechanism.
2. The cutting device for recyclable cyclic fillers according to claim 1, characterized in that The clamp consists of a U-shaped clamping rod and a screwing component. The U-shaped clamping rod is movably connected to the screwing component, and a clamping hole is provided inside the U-shaped clamping rod.
3. The cutting device for recyclable fillers according to claim 1, characterized in that... The cutting mechanism includes a cutting frame, a rotary motor B, a fixing component, a moving plate, a rotating rod, and cutting blades. The cutting frame is fixedly installed at the front end of the frame body. A moving slot is provided inside the cutting frame, and a moving plate is installed in the moving slot. The rotary motor B is connected to one side of the moving plate. The output end of the rotary motor B passes through the moving plate and is connected to the rotating rod. Multiple cutting blades are connected to the rotating rod. The moving plate is detachably connected to the cutting frame through the fixing component.
4. The cutting device for recyclable fillers according to claim 1, characterized in that... The expansion and cutting mechanism includes a first gear, a second gear, a connecting gear, a driven gear, a chain, a driving gear, a rotary motor D, a first expansion and cutting roller, and a second expansion and cutting roller.
