Description

Technical Field

[0001] The present application belongs to the technical field of aluminum honeycomb core production, and in particular relates to a high-speed cutter for aluminum foil. Background Art

[0002] The aluminum honeycomb core is a regular hexagonal honeycomb core formed by laminating and stretching multiple layers of aluminum foil. The commonly used aluminum honeycomb core material is aluminum foil with a thickness of 0.01-0.1 mm. It has the advantages of clean and flat surface, high strength, corrosion resistance and aging resistance.

[0003] In the fixed-length cutting section of the aluminum honeycomb glue coating machine, the aluminum sheet needs to be cut into the same size as the aluminum honeycomb core to facilitate its bonding with the adhesive. The existing equipment for cutting aluminum sheets basically uses the upper cutter to cut the aluminum sheet downward with the lower cutter below, and the aluminum sheet needs to be paused between the upper cutter and the lower cutter before the cutting is completed, that is, the other traction rollers need to stop traction. When the cutting is completed, the traction continues and the aluminum sheet is sent between the upper cutter and the lower cutter for cutting. This pause time greatly affects the cutting speed.

There are two cutting knife brackets 3.1, which are respectively installed on both sides of the frame of the traction roller group 1. The rotating knife frame 3.2 is installed between the two cutting knife brackets 3.1. The servo drive motor 3.4 is installed on one side of the cutting knife bracket 3.1, and its output shaft is connected to the mounting shaft of the rotating knife frame 3.2 through a universal joint coupling. The servo drive motor 3.4 drives the rotating knife frame 3.2 to rotate, and then drives the upper cutting knife 3.3 to rotate. When the upper cutting knife 3 .3 is located above the lower cutter 4, the rotation direction is opposite to the traction direction, when the upper cutter 3.3 is located below the lower cutter 4, the rotation direction is the same as the traction direction, when the lower cutter 4 and the lower cutter 3.3 blades are aligned, the lower cutter 4 and the upper cutter 3.3 are on the same plane, the rotating upper cutter 4 can cut the aluminum film without stopping traction, and does not hinder the traction; the servo drive motor 3.4 can be a reduction motor, a servo motor, etc. The servo drive motor adopts a cam control mode, which is convenient for setting the cutter speed. The upper cutter rotation speed can be set according to the length of the aluminum film, and then aluminum films with different length requirements can be cut.

[0029] The rotating tool holder 3.2 is a cylinder, and a mounting groove 3.21 is opened on the rotating tool holder 3.2 along the axial direction. The bottom surface of the mounting groove 3.21 coincides with the axis of the rotating tool holder 3.2. The upper cutter 3.3 is installed in the mounting groove 3.21.
