In this embodiment, the winding mechanism includes an upper winding mechanism and a lower winding mechanism (such as Figure 1 ), the number of winding mechanisms is determined according to the number of finished aluminum foil rolls after slitting.

[0018] A large roll of aluminum foil 19 to be slit is installed on the uncoiler 1, and a bridge frame 2 is provided between the uncoiler 1 and the slitting main machine 4. In this embodiment, the uncoiler 1 is an uncoiler on an existing aluminum foil slitting machine, so it is not described in detail. The aluminum foil strip 3 released by the uncoiler 1 first passes through the bridge frame 2, and a plurality of conduction rollers 5 are installed on the bridge frame 2. The conduction rollers 5 are used to introduce the aluminum foil strip 3 in the uncoiler 1 into the slitting main machine 4, and the aluminum foil strip 3 is threaded on each conduction roller 5.

[0019] The bridge frame 2 is provided with heating lamps 6 located on both sides of the aluminum foil strip 3, and the irradiation direction of the heating lamps 6 is toward the aluminum foil strip 3. The bridge frame 2 is provided with air knife tubes 7 located on both sides of the aluminum foil strip 3, and the air outlet ends of the air knife tubes 7 are toward the aluminum foil strip 3. The heating lamps 6 and the air knife tubes 7 are arranged in sequence along the traveling direction of the aluminum foil strip 3.

[0020] In this embodiment, if Figure 1 As shown, two groups of heating lamps 6 are arranged on the bridge frame 2, wherein one group of heating lamps 6 faces the front side of the aluminum foil strip 3, and the other group of heating lamps 6 faces the back side of the aluminum foil strip 3.

[0021] Specifically, Figure 2 As shown, a first support rod 8 is provided at the upper end of the bridge frame 2, a second support rod 10 is fixed on the first support rod 8, an end of the second support rod 10 is hinged to one end of a mounting seat 9, the baking lamp 6 facing the front of the aluminum foil strip 3 is fixed on the mounting seat 9, and the other end of the mounting seat 9 is connected to an adjustment mechanism, which is used to adjust the inclination of the mounting seat 9.

[0022] The adjustment mechanism includes a rope 13, a first hinge seat 11 fixed to one end of the first support rod 8 away from the bridge frame 2, and a second hinge seat 12 fixed to the other end of the first support rod 8. The second hinge seat 12 is rotatably connected to a rotating shaft. One end of the rope 13 is fixed to the rotating shaft, and the other end passes through the first hinge seat 11 and is fixed to the mounting seat 9. In this embodiment, the external machine that drives the rotating shaft to rotate can be an electric motor, a motor or manual, and its rotation can be controlled.

The pinch roller 17 includes two roller shafts arranged in pairs to flatten the aluminum foil strip 3 after slitting. After the two aluminum foil strips 3 are cut, they pass through the pinch rollers 17 and are led to the upper winding mechanism or the lower winding mechanism via the corresponding separation rollers 18 to form a first finished aluminum foil roll 20 and a second finished aluminum foil roll 21 .

[0026] When in use, the unwinder 1 with the large aluminum foil roll 19 to be cut is turned on, and the aluminum foil strip 3 released by the unwinder 1 first passes through the bridge frame 2. After the movable end of the aluminum foil strip 3 passes through each conductive roller 5 in the bridge frame 2, it enters the slitting main machine 4, and the aluminum foil strip 3 is threaded on each conductive roller 5. Finally, it is cut into two aluminum foil strips 3 through the cooperation of the grooved knife roller 15 and the knife 16, and then guided to the upper winding mechanism or the lower winding mechanism through the corresponding separation roller 18 to form the first finished aluminum foil roll 20 and the second finished aluminum foil roll 21. In this process, the heating lamps 6 and the air knife tubes 7 on both sides of the aluminum foil strip 3 are always in the on state to clean the rolling oil and aluminum powder on the surface of the aluminum foil strip 3.
