The dish knife is the core part of the aluminum foil slitting machine, which directly determines the quality of the aluminum foil slitting and represents the technical level of the aluminum foil slitting machine. The disc cutter structure is optimized for the problems existing in the existing disc cutter. The optimized disc-shaped knife has no radial slotting, and the overall rigidity is good and the precision is high. The disc-shaped blade has the same positioning reference, accurate positioning, and does not swing during use. The movement and locking of the disc cutter on the cutter shaft changes the previous idea of ​​using the radial groove of the cutter seat to shrink, and the method of adding a positioning key and a ring spring on the seat is used instead. The optimized disc-shaped knife can ensure the positioning accuracy of the disc-shaped blade and realize the movement and locking of the disc-shaped knife on the cutter shaft. In the production application, the disc-shaped aluminum foil has no burrs and curled edges at the edges, and has been well received by users, which has won the market for the enterprise.

During the use of the disc-shaped knife, according to the different cutting width of the aluminum foil, the movement of the disc-shaped knife on the cutter shaft can be realized, and the radial slot of the cutter seat can realize this function, which is the design idea of ​​the existing disc-shaped cutter. However, the radial deformation of the tool holder will cause machining deformation, which will reduce the accuracy of the tool holder, and thus cause quality problems such as burrs and curling of the edge of the aluminum foil after slitting. The improvement idea of ​​the existing butterfly knife structure is proposed: under the requirement of using the function, the overall rigidity of the knife seat is ensured, and the radial slotting is avoided. The disc-shaped insert is mounted on the seat, and is positioned by the stepped surface of the seat, and the spring presses the blade. The locating pin cooperates with the hole in the disc blade to prevent the blade from rotating. When the width of the slit aluminum foil changes, the screw is loosened, and under the action of the annular spring, the positioning key moves away from the center of the holder, and there is a slight gap between the holder and the cutter shaft, and the disc cutter moves on the cutter shaft. After adjusting to the proper position, tighten the screw and push the positioning button to move toward the center of the holder, so that the gap between the holder and the cutter shaft becomes smaller, and the holder is tightly hung on the cutter shaft. The optimized disc-shaped knife has a simple structure, and the blade seat has no radial groove, which effectively reduces the processing cost and improves the precision. During use, the disc-shaped insert has high positioning accuracy, no wobble phenomenon, and high reliability. The optimized disc-shaped knife can effectively improve the cutting precision of the aluminum foil and solve the problem of edge burr and curling.
