[0107] Embodiment 2

[0108] This embodiment is basically the same as Embodiment 1 in structure,

[0109] The difference is that, as Figure 4 shown; a receiving roller 3 rotatably connected to the L-shaped receiving plate 5 is provided on the L-shaped receiving plate 5; a circular hole is opened in the middle of the L-shaped receiving plate 5; the core shaft 4 passes through the circular hole for receiving materials; the highest point of the outer circle of the receiving roller 3 is higher than the upper plane of the L-shaped receiving plate 5, which is convenient for the aluminum foil inner lining paper roll 37 to abut against the outer circle of the receiving roller 3;

[0110] There are two rows of the receiving rollers 3, which are respectively arranged on both sides of the circular hole; the advantage of this is that the aluminum foil inner lining paper roll 37 will not be eccentric on the receiving roller 3, which is convenient for movement;

[0111] By providing the receiving roller 3, it is convenient for the aluminum foil inner lining paper roll 37 to be transported on the conveying track. If the receiving roller 3 is not provided, the L-shaped receiving plate 5 abuts against the end face of the aluminum foil inner lining paper roll 37, and the friction is very large, which is not convenient for transportation on the conveying track. If there is no conveying roller 3 and the aluminum foil roll is pushed with too much external force, the aluminum foil inner lining paper roll 37 is likely to be damaged.

[0112] The working principle of this embodiment is basically the same as that of Embodiment 1, and will not be elaborated here.

[0113] Embodiment 3

[0114] This embodiment is basically the same as Embodiment 1 in structure,

[0115] The difference is that a rib plate is provided on the bracket 14, and the rib plate is riveted to the base 15, which can enhance the strength of the bracket 14. In this way, a thinner square steel can be used for the bracket 14, saving raw materials.

[0116] The working principle of this embodiment is basically the same as that of Embodiment 1, and will not be elaborated here.

[0117] Embodiment 4

[0118] This embodiment is basically the same as Embodiment 1 in structure,

[0119] The difference is that a centering shaft head 8 is provided at the end of the guide sleeve 9; the distance between the centering shaft head 8 and the mandrel 4 is between 10 mm and 15 mm, and the outer diameter of the centering shaft head 8 is the same as the outer diameter of the mandrel, facilitating the smooth feeding of the aluminum foil roll from the guide sleeve 9 onto the mandrel 4.

[0120] The working principle of this embodiment is basically the same as that of Embodiment 1, and will not be elaborated here.

[0121] The above has described in detail the preferred embodiments of this patent. However, this patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of this patent within the scope of knowledge possessed by ordinary technicians in the art.
