[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 7 It can be seen that an aluminum foil food bag slitting mechanism includes a frame 1, a traction roller 2 is provided at the end of the frame 1, the end of the aluminum foil food bag is wound on the traction roller 2, a support roller 3 is provided in the middle of the frame 1, a cutting roller is provided above the support roller 3, the cutting roller includes a core shaft 4, the interior of the core shaft 4 is empty, a rotating shaft 5 is rotatably arranged inside the core shaft 4, a connecting block 6 is arranged on the rotating shaft 5, a key strip 7 is provided on the core shaft 4, a plurality of through holes 8 are opened on the key strip 7, the connecting block 6 is located in the through hole 8, a cutting sleeve 9 is provided on the outside of the core shaft 4, and the cutting sleeve 9 is threadedly connected to the connecting block 6.

[0020] When the utility model is used in a specific way,

[0021] The aluminum foil food bag is wound on the traction roller 2, and the traction roller 2 drives the aluminum foil food bag to feed forward. The support roller 3 and the cutting roller rotate to complete the slitting of the aluminum foil food bag. The traction roller 2 winds up the cut waste and collects the cut finished products.

[0022] In the present device, the cutting roller adopts a split structure, the cutting sleeve 9 and the core shaft 4 can be removed, and the cutting edge is set on the cutting sleeve 9. When the cutting edge is maintained, the cutting sleeve 9 can be removed from the core shaft 4. The cutting sleeve 9 is small in size, easy to repair and organize, easy to maintain, and low in maintenance cost.

[0023] A plurality of supporting legs 10 are provided at the bottom of the frame 1, and the height of the supporting legs 10 is adapted to the height of the production line for easy docking.

[0024] A first motor 11 for driving the traction roller 2 and a second motor 12 for driving the roller 3 are provided on the side of the frame 1. The end of the core shaft 4 is engaged with the end of the roller 3 through gear transmission. The speed of the first motor 11 is matched with the speed of the second motor 12 to ensure the smooth feeding and perfect coordination of the slitting of the aluminum foil food bag.

[0025] There are three connecting blocks 6. The connecting block 6 located in the middle is rotatably connected to the rotating shaft 5. The connecting blocks 6 located on both sides are threadedly connected to the rotating shaft 5, and the threads on both sides of the rotating shaft 5 have opposite rotation directions, so that the rotating shaft 5 rotates so that the connecting blocks 6 located on both sides move in opposite directions. The connecting block 6 in the middle always remains stationary, and the cutting sleeve 9 located in the middle always maintains the midline position. The cutting sleeves 9 on both sides move with the movement of the connecting block 6, and the distance between the cutting sleeves 9 on both sides and the cutting sleeve 9 in the middle is consistent, which is compatible with the aluminum foil food bag to ensure the accuracy of the cutting position.

[0026] The cutting sleeve 9 is provided with a key groove 13 matched with the key bar 7 , so as to form a structure in which the cutting sleeve 9 and the mandrel 4 rotate synchronously without affecting the movement of the cutting sleeve 9 outside the mandrel 4 .

[0027] The cutting sleeve 9 is provided with a mounting hole 14, and the connecting block 6 is provided with a threaded hole 15. The screw passes through the mounting hole 14 and is threadedly connected to the connecting block 6. The mounting hole 14 is located at a non-cutting edge position and does not affect the cutting effect of the cutting edge on the aluminum foil food bag.

[0028] Compared with the prior art, the utility model has the following beneficial effects: the cutting roller adopts a split structure, which can separate the cutting sleeve from the core shaft, reduce the volume of the cutting sleeve, facilitate maintenance and repair, and greatly reduce the production cost and maintenance cost; at the same time, the distance between the cutting sleeves is adjustable, which can adapt to the slitting processing of aluminum foil food bags of various specifications.
