[0027] Example 1
[0028] like Figs. 1-3 As shown, this embodiment provides a roll unwinding device, including an unwinding frame 1 and a feeding mechanism 2 located on one side of the unwinding frame 1. The unwinding frame 1 is provided with an unwinding shaft 4 and a supporting mechanism 3. The feeding mechanism 2 includes a base plate 21, a movable plate 22 and a feeding plate 23. The movable plate 22 is slidably installed on the base plate 21. The feeding plate 23 is located above the movable plate 22 and a lifting component is provided between the two. A placement rack is provided on the top of the feeding plate 23.
[0029] The coil material is lifted and lowered via the feeding plate 23, the placement rack, and the lifting assembly. The coil material is moved via the movable plate 22 and the base plate 21, allowing it to be fitted onto the unwinding shaft 4. No manual lifting of the coil material is required, making operation simple, time-saving, and labor-saving. The supporting mechanism 3 supports the coil material, preventing the outer aluminum sheet from shifting and also preventing movement on the unwinding shaft, thus improving the coil material's stability.
[0030] In a specific embodiment of this invention, the lifting assembly includes a first cylinder 26 located at both ends of the movable plate 22, and the driving end of the first cylinder 26 is fixedly connected to the loading plate 23. In use, the first cylinder 26 drives the loading plate 23 to rise, simultaneously driving the placement rack on the loading plate 23 to rise, thereby raising the roll material on the placement rack so that the center position of the roll material is directly opposite the unwinding shaft 4.
[0031] In this specific embodiment, the bottom of the movable plate 22 is provided with rollers, and the surface of the base plate 21 is provided with a slide rail 25, in which the rollers are installed. After the center position of the roll material is aligned with the unwinding shaft 4 by the first cylinder 26, the movable plate 22 moves on the base plate 21, that is, the rollers slide within the slide rail 25, until the roll material is completely wrapped around the outside of the unwinding shaft 4. Then, the first cylinder 26 drives the feeding plate 23 to descend, allowing the roll material to be hung on the unwinding shaft 4, realizing rapid feeding of the roll material. The operation is simple and saves time and effort.
[0032] In a specific embodiment of this invention, the placement rack includes placement plates 24 located at both ends of the feeding plate 23, and the upper surface of the placement plates 24 is curved. The two placement plates 24 work together to facilitate the stable placement of the roll material on the feeding plate 23, and the curved surface design facilitates the handling of roll materials of different diameters, enabling rapid loading of roll materials of different diameters.
[0033] In a specific embodiment of this invention, the supporting mechanism 3 includes supporting plates 31 rotatably mounted on both sides of the unwinding frame 1, with the two supporting plates 31 located on both sides of the unwinding shaft 4. A first connecting plate 32 is hinged to the supporting plates 31, a second connecting plate 33 is hinged to the first connecting plate 32, and a mounting plate 34 is fixedly connected to the second connecting plate 33. A second cylinder 35 is provided at the top of the unwinding frame 1, and the driving end of the second cylinder 35 is fixedly connected to the mounting plate 34. The supporting plates 31 can abut against the outer side of the roll material. In use, the second cylinder 35 drives the mounting plate 34 to rise, simultaneously driving the second connecting plate 33 to rise, causing the first connecting plate 32 to rotate, thus moving the supporting plates 31 until the supporting plates 31 abut against the outer side of the roll material, achieving the abutment against the roll material.
[0034] The drive end of the first cylinder 26 and the feeding plate 23, and the drive end of the second cylinder 35 and the mounting plate 34 can be fixedly connected by bolts or by welding.
[0035] In a specific embodiment of this invention, two abutment plates 31 are provided on the same side of the unwinding shaft 4, and an abutment roller 36 is provided between the two abutment plates 31. The abutment roller 36 can extend the abutment length of the roll material, further improving the stability of the roll material during unwinding.
[0036] In a specific embodiment of this invention, a protective pad is fitted around the outside of the abutting roller 36. The protective pad protects the roll material and prevents the abutting roller 36 from abrading the roll material.
[0037] In a specific embodiment of this invention, the unwinding frame 1 includes a vertical plate 11 and a horizontal plate 12. The second cylinder 35 is mounted on the top of the horizontal plate 12, and a mounting base 13 is provided at the bottom of the horizontal plate 12. A connecting rod 14 is fixed on the mounting base 13, and one end of the abutment plate 31 is rotatably connected to the connecting rod 14. Preferably, four mounting bases 13 are provided at the bottom of the horizontal plate 12, and the mounting bases 13 located on the same side of the roll are connected by connecting rods 14.
[0038] The working principle of a coil unwinding device is as follows: An aluminum coil 100 is placed on a placement plate 24. A first cylinder 26 drives a feeding plate 23 to rise, simultaneously raising the aluminum coil 100 until its center is directly aligned with the unwinding shaft 4. Then, a movable plate 22 moves on a base plate 21, gradually bringing the aluminum coil 100 closer to the unwinding shaft 4 until it is completely wrapped around the outside of the unwinding shaft 4. Finally, the first cylinder 26 drives the feeding plate 23 to descend, allowing the aluminum coil 100 to hang on the unwinding shaft 4, thus achieving rapid feeding of the aluminum coil 100. The second cylinder 35 drives the mounting plate 34 to rise, which in turn drives the second connecting plate 33 to rise, causing the first connecting plate 32 to rotate. This causes the first connecting plate 32 to drive the abutment plate 31 to move toward the aluminum coil 100 until the abutment roller 36 abuts against the outside of the aluminum coil 100. The material is then released from the bottom of the aluminum coil 100, achieving stable unwinding of the aluminum coil 100.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
