[0002] Aluminum coils and sheets are rectangular thin sheet materials made from aluminum through processes such as rolling and calendering. They are lightweight and corrosion-resistant, and are widely used in the production of aluminum parts. Aluminum coils and sheets need to be rolled into different thicknesses and widths by a cold rolling mill, and then slit by a slitting machine. When producing aluminum parts, aluminum coils and sheets need to be unwound.

[0003] Existing aluminum coil unwinding devices are not convenient for quickly positioning the aluminum coil on the rotating seat during actual use, and the coating on the aluminum coil is not easy to detach from the sheet, affecting the coating winding and recycling. A new aluminum sheet unwinding device for aluminum parts production is proposed to solve the above problems. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-6A device for unwinding aluminum sheet raw materials for aluminum parts production includes a drive base 1 and an aluminum sheet roll 2. A rotating shaft 3 is provided on the right side of the drive base 1, and a limiting seat 4 is provided at one end of the rotating shaft 3 near the drive base 1. Four cross-shaped arc-shaped blocks 5 are fixedly connected to the right side wall of the limiting seat 4 away from the center. The aluminum sheet roll 2 is fitted onto the four arc-shaped blocks 5. Positioning components are provided on the arc-shaped upper surface of two of the arc-shaped blocks 5 away from the limiting seat 4. The positioning components abut and press against the aluminum sheet roll 2. The positioning components include circular grooves 6 provided on the arc-shaped upper surface of two of the arc-shaped blocks 5. Both circular grooves 6 are located away from the limiting seat 4, and springs 7 are fixedly connected to the opposite inner walls of the two circular grooves 6. Two springs 7 are fixedly connected to positioning blocks 8 at their ends away from the inner wall of the circular groove 6. Both positioning blocks 8 have arc-shaped end faces on their side walls away from the limiting seat 4. The aluminum sheet roll 2 is aligned with the four cross-shaped arc-shaped blocks 5 on the limiting seat 4, so that the aluminum sheet roll 2 and the arc-shaped end faces of the two positioning blocks 8 come into contact. After the two positioning blocks 8 are subjected to force, they compress the springs 7 in the circular groove 6 until the aluminum sheet roll 2 can be fitted onto the four cross-shaped arc-shaped blocks 5. At this time, the compressed springs 7 elastically reset and drive the positioning blocks 8 to move out of the circular groove 6. Thus, the springs 7 cooperate with the positioning blocks 8 to position the aluminum sheet roll 2 on the four arc-shaped blocks 5, which facilitates quick positioning of the aluminum sheet roll 2.

[0019] A film-coated recycling assembly is provided on the annular sidewall of the rotating shaft 3 away from the limiting seat 4. The film-coated recycling assembly includes four fixing rods 9 fixedly connected to the annular sidewall of the rotating shaft 3 away from the limiting seat 4. The four fixing rods 9 are respectively positioned opposite four arc-shaped blocks 5. Each of the four fixing rods 9 has a threaded joint 10 at one end away from the rotating shaft 3 and a fixing block 11 at the other end away from the rotating shaft 3. Each of the four fixing blocks 11 has a threaded hole 12 on the sidewall facing the fixing rods 9. The four threaded joints 10 are respectively threaded into the four threaded holes 12. The four fixing blocks 11 are connected by an arc-shaped slot 13 on the side wall away from the fixing rod 9. The fixing blocks 11 are connected to the fixing rod 9, so that the threaded joint 10 and the threaded hole 12 position the fixing blocks 11 on the fixing rod 9. The cross-shaped fixed blocks 11 and the arc-shaped slot 13 are used to roll up the film on the aluminum sheet roll 2, which facilitates the recycling of the film on the aluminum sheet roll 2. The threaded joint 10 and the fixing rod 9 are integrally cast. The fixing rod 9 is welded to the rotating shaft 3 and the arc block 5 is welded to the limiting seat 4.

[0020] A film-coating limiting component is provided on the side of the drive base 1. The film-coating limiting component slides and abuts against the unwound aluminum sheet of the aluminum roll 2. The film-coating limiting component includes an arc-shaped limiting block 14 disposed on the side of the drive base 1. A sliding ball 15 is embedded in the arc-shaped inner wall at the center of the arc-shaped limiting block 14. The arc-shaped inner wall of the arc-shaped limiting block 14 slides and abuts against the unwound aluminum sheet of the aluminum roll 2. The sliding ball 15 rolls and abuts against the unwound aluminum sheet of the aluminum roll 2. Rectangular ring-shaped counterweights 16 are sleeved on the lower ends of both sides of the arc-shaped limiting block 14. 16 are connected and fixed to the arc-shaped limiting block 14 using double-headed bolts 17. The arc-shaped limiting block 14 is hung on the unwinding aluminum sheet of the aluminum sheet roll 2. Two rectangular ring-shaped counterweights 16 made of alloy steel are fixed to the arc-shaped limiting block 14 with double-headed bolts 17. The arc-shaped limiting block 14, together with the sliding ball 15 and the rectangular ring-shaped counterweight 16, provides a limit for the unwinding aluminum sheet, so that the aluminum sheet and the coating can be easily separated, which facilitates the recycling of the aluminum sheet coating. The arc-shaped limiting block 14 is made of wear-resistant nylon, and the rectangular ring-shaped counterweight 16 is made of alloy steel.

[0021] In use, this utility model involves aligning the aluminum sheet roll 2 with the four cross-shaped arc-shaped blocks 5 on the limiting seat 4, causing the aluminum sheet roll 2 to abut against the arc-shaped end faces of the two positioning blocks 8. This forces the two positioning blocks 8 to compress the spring 7 within the circular groove 6 until the aluminum sheet roll 2 can be fitted onto the four cross-shaped arc-shaped blocks 5. At this point, the compressed spring 7 elastically resets, causing the positioning blocks 8 to move out of the circular groove 6. Thus, the spring 7, in conjunction with the positioning blocks 8, positions the aluminum sheet roll 2 onto the four arc-shaped blocks 5, facilitating quick and easy positioning of the aluminum sheet roll 2. The structure is simple and practical. The fixing block 11 is aligned with the fixing rod 9, making... The threaded connector 10, in conjunction with the threaded hole 12, positions the fixing block 11 on the fixing rod 9. The cross-shaped fixing blocks 11, in conjunction with the arc-shaped slot 13, wind up the coating on the aluminum sheet roll 2, facilitating the recycling of the coating on the aluminum sheet roll 2. The arc-shaped limiting block 14 is attached to the unwinding aluminum sheet of the aluminum sheet roll 2. Two rectangular ring-shaped counterweights 16 made of alloy steel are fixed to the arc-shaped limiting block 14 with double-headed bolts 17. This allows the arc-shaped limiting block 14, in conjunction with the sliding ball 15 and the rectangular ring-shaped counterweight 16, to limit the unwinding aluminum sheet, making it easy to separate the aluminum sheet from the coating and facilitating the recycling of the aluminum sheet coating.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
