Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution: an aluminum coil online film tearing device, including a conveyor table 1, a conveyor belt 10 for conveying aluminum coils is arranged in the conveyor table 1, a film cutting mechanism 3 for tearing aluminum films is arranged directly above the conveyor belt 10, a plurality of groups of legs 15 are fixedly connected to the lower surface of the conveyor table 1, a winding roller 14 is rotatably connected between two of the legs 15, and one end of the winding roller 14 penetrates through the legs 15 and is driven by a winding motor 13;

[0021] The film cutting mechanism 3 includes a vertical frame 31, a vertical rod 32, a connecting block 35 and two groups of expanding blocks 38. The vertical rod 32 is slidably inserted into the upper end of the vertical frame 31, the lower end of the vertical rod 32 is fixedly connected to the upper surface of the connecting block 35, a first spring 34 is arranged outside the vertical rod 32, square shafts 37 penetrating through the expanding blocks 38 are fixedly connected to both sides of the connecting block 35, a square hole 381 for the square shaft 37 to slide and be inserted is opened on one side of the expanding block 38, an aluminum film warping part 351 is arranged on the side of the connecting block 35 adjacent to the two square shafts 37, an aluminum film cutter 36 is arranged on the upper surface of the aluminum film warping part 351, the cross section of the aluminum film warping part 351 is triangular, and expanding warping parts 382 are arranged on the side of the two groups of expanding blocks 38 adjacent to the square shafts 37.

[0022] The upper surface of the unfolding block 38 is fixedly connected with a telescopic sleeve rod 313. The upper end of the telescopic sleeve rod 313 is fixedly connected with a slider 312. The top of the inner cavity of the vertical frame 31 is fixedly connected with a guide frame 311 for the slider 312 to slide. The upper end of the vertical rod 32 penetrates through the vertical frame 31 and is fixedly connected with a pull ring 33. By means of the pull ring 33, it is convenient to lift the connecting block 35, thus facilitating the passing of the aluminum coil. At the same time, the stability of the film cutting mechanism 3 is improved through the guide frame 311 and the slider 312, avoiding the angle inclination of the film cutting mechanism 3.

[0023] Positioning bolts 310 are inserted into the upper surfaces of the two groups of unfolding blocks 38. Positioning holes 39 for the threaded connection of the positioning bolts 310 are provided on the upper surface of the square shaft 37. By installing the positioning bolts 310 in different positioning holes 39, the position adjustment of the two groups of unfolding blocks 38 is facilitated, so as to tear the film of aluminum coils of different specifications.

[0024] Two groups of fixing plates 2 are fixedly connected to the upper surface of the conveying table 1. A film unwinding guiding assembly is arranged between the two groups of fixing plates 2. A limiting mechanism 9 for guiding the wire of the aluminum coil is arranged in the inner cavity of the conveying table 1. The use of the film unwinding guiding assembly can improve the stability of the aluminum coil unwinding. At the same time, the stability of the aluminum coil conveying is improved through the limiting mechanism 9, avoiding the curling of the aluminum coil.

[0025] The film unwinding guiding assembly includes a film unwinding roller 6, a first guiding roller 7 and a second guiding roller 8 rotatably connected between the two groups of fixing plates 2. One end of the film unwinding roller 6 penetrates through the fixing plate 2 and is driven by a film unwinding motor 5. Driving the film unwinding roller 6 by the film unwinding motor 5 facilitates the unwinding of the aluminum coil, and then under the action of the first guiding roller 7 and the second guiding roller 8, the aluminum coil is unwound, improving the stability of the unwinding.

[0026] The limiting mechanism 9 includes two groups of mounting blocks 95. Guide rods 93 are inserted into the two groups of mounting blocks 95. A second spring 94 is sleeved on the outer side of the upper end of the guide rod 93. A pressing roller 92 is rotatably connected to the opposite side of the two groups of mounting blocks 95. A fixed roller 91 is arranged below the pressing roller 92. The second spring 94 can make the pressing roller 92 on the mounting block 95 press on the aluminum coil, thus ensuring the stability of the aluminum coil during transportation on the conveyor belt 10.

[0027] Mounting grooves 4 for the sliding connection of the mounting blocks 95 are provided on both sides of the inner cavity of the conveying table 1. An aluminum film guide roller 11 and a limiting roller 12 are rotatably connected to one end of the inner cavity of the conveying table 1 far from the fixed roller 91. The aluminum film guide roller 11 can reduce the friction between the aluminum film and the conveyor belt 10, thus avoiding the breakage of the aluminum film and reducing faults.

[0028] In use, a part of the aluminum coil on the unwinding roller 6 is drawn out, and the aluminum coil passes through the first guiding roller 7, the second guiding roller 8 and the limiting mechanism 9 in sequence. The end of the aluminum film is torn from the middle and fixed on the winding roller 14. At the same time, the connecting block 35 is pressed against the surface of the aluminum coil under the elastic action of the first spring 34. The winding motor 13, the unwinding motor 5 and the conveyor belt 10 are started. The unwinding motor 5 continuously unwinds the aluminum coil on the unwinding roller 6, and then continuously horizontally conveys the aluminum coil under the action of the conveyor belt 10. When the aluminum coil passes through the connecting block 35, the aluminum film is lifted by the aluminum film lifting part 351. The lifted aluminum film is slit by the aluminum film cutter 36 and is unfolded outward through the unfolding part. Then, under the action of the winding roller 14, the torn aluminum film is wound up, reducing the labor intensity of workers, facilitating the collection of the aluminum film after tearing, reducing the amount of manual labor, and improving the efficiency of film tearing.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
