[0002] The mouth strip is a component used to be attached to the inner side of the open end of the packaging box. The mouth strip needs to be cut and scored during the production process. Traditionally, a creasing machine is used to cut and score the mouth strip. The working principle of the creasing machine is to place the mouth strip substrate into the creasing lower mold, and then control the creasing upper mold to descend and cooperate with the creasing lower mold to cut and score the mouth strip. The defects of this method are: after the cutting and creasing are completed, it is necessary to wait for the upper and lower molds to be separated and taken out and a new mouth strip substrate to be placed, resulting in low processing efficiency, high labor intensity for workers, and the hands may be crushed by the mold, posing a safety hazard; in addition, if the mouth strip substrate is not accurately placed in a specific position, the subsequent cutting and scoring will also be affected.

The mobile drive assembly includes a first motor, and the output end of the first motor is connected to the driving screw 30 for transmission. The driving screw 30 is screwed to the pushing rack 2. The pushing rack 2 is connected with a guide seat 28, and the frame is provided with a guide rail 29 passing through the guide seat 28. By controlling the first motor to drive the driving screw 30 to rotate, the pushing rack 2 and the pushing strip 25 can be driven to move. The pushing strip 25 can push the mouth strip substrate at the bottom of the storage rack 1 to move, and the thickness of the pushing strip 25 is less than the thickness of the mouth strip substrate. The other side of the corresponding storage rack 1 is sequentially provided with a cutting assembly and a transfer conveyor belt 4, and the cutting assembly includes a cutting knife group arranged on the left and right, and two cutting knife groups are arranged between the two cutting knife groups.

The first lower knife wheel 10 and the second lower knife wheel 8 are arranged on the driving shaft 12, and the driving shaft 12 is connected to the second motor by driving. The second motor is controlled to drive the driving shaft 12 to rotate , which can drive the first and second lower cutter wheels to rotate, and then cooperate with the cutting circular knife 11 and the cutting circular knife 9. Further, the first upper tool holder 15 is arranged in the slide groove on the first tool holder seat 20, and the first upper tool holder 15 is screwed with the first adjustment screw 18 rotatably arranged on the first tool holder seat 20, and the second upper tool holder 16 is arranged in the slide groove on the second tool holder seat 21, and the second upper tool holder 16 is screwed with the second adjustment screw 22 rotatably arranged on the second tool holder seat 21. By controlling the rotation of the first and second adjustment screws, the first and second tool holder seats can be driven to rise and fall, and then the height positions of the cutting circular knife 11 and the cutting circular knife 9 can be adjusted. The first tool holder seat 20 and the second tool holder seat 21 can both be slidably arranged on the frame rod 24, and locked and positioned by the locking block 23. By loosening the locking block, the first and second tool holder seats can be controlled to move horizontally along the frame rod 24 to adjust the left and right positions of the cutting circular knife 11 and the cutting circular knife 9. A first gear 27 is provided on the first tool holder seat 20, and a second gear 26 is provided on the second tool holder seat 21. The first and second gears are both engaged with the rack 19 on the frame. The rack 19 is arranged axially along the frame rod 24. The movement of the first and second tool holder seats can be achieved by controlling the first and second gears, which makes the operation more convenient and the adjustment more precise.A transition plate 6 is arranged between the cutting knife group and the scoring knife group and the transfer conveyor belt 4. The transition plate 6 is arranged obliquely. A blanking trough 14 is arranged at the transition plate 6 corresponding to the cutting knife group. A waste box is arranged below the blanking trough 14, so that the waste of the strip substrate after the two ends are cut off can fall from the blanking trough 14 into the waste box, and the strips after cutting and scoring will slide from the transition plate 6 to the transfer conveyor belt 4. A positioning plate 5 is arranged corresponding to the transfer conveyor belt 4 to position the strip so that it can be positioned and sent to the next workstation, and it is ensured that it will not fall off from the transfer conveyor belt 4 after sliding.

[0023] The working principle of the utility model is: first, the pushing rack 2 will drive the pushing strip 25 to move to the stacking rack 1 and push the bottom strip substrate of the stacked strips to the cutting knife group and the cutting knife group. The cutting knife group will cut off the excess waste at both ends of the strip substrate to obtain the strip of the required length. The cutting knife group will cut two folds in the strip. After that, the strip is pushed to the transition plate 6 and naturally falls onto the transfer conveyor belt 4. The transfer conveyor belt 4 drives the strip to the next processing station.

[0024] The structure of the utility model can realize the automatic pushing of the strip substrate by adopting the cooperation of the material storage rack and the pushing mechanism, and can realize the fixed-length cutting of both sides of the strip substrate and cut folds inside the strip substrate by the cooperation of the cutting knife group and the cutting knife group. It only needs to set the positions of the cutting knife group and the cutting knife group to ensure the accuracy of the cutting and cutting operations, and after the cutting is completed, it can directly fall onto the transfer conveyor belt and be transported to the next processing station, replacing the traditional processing method of using a creasing machine, realizing automatic operation throughout the process, greatly reducing the labor intensity of workers, improving their safety, and improving processing efficiency.
