[0042] The working principle of this utility model:
[0043] First, the staff can install the utility model on the production line of the bag making machine, so that the plastic bags that need to be die-cut after transportation can pass between the lower die base 21 and the upper die knife 24, which is convenient for die-cutting. Then, when in use, the staff turns on the third motor 13, and the third motor 13 drives the rotating shaft 14 to rotate, and the rotation of the rotating shaft 14 drives the eccentric piece 15 to rotate, and the frequency of the die-cutting of the plastic bag by the upper die knife 24 is adjusted by adjusting the rotation frequency of the eccentric piece 15. When the upper die knife 24 is die-cutting, the self-gravity of the pressing plate 25 generates a downward force on the first spring 27, so that the initial position of the pressing plate 25 is closer to the lower die seat 21 than the initial position of the upper die knife 24, so the pressing plate 25 will first contact the plastic bag on the lower die seat 21, and as the upper die seat 16 continues to move downward, the first spring 27 will be squeezed at this time, so that the first spring 27 generates a reset force, and the reset force pushes the pressing plate 25, so that the fixing effect of the pressing plate 25 on the plastic bag is more stable, thereby improving the cutting stability of the plastic bag by the upper die knife 24, and through the action between the connecting plate 17 and the fixing column 19 and the second spring 18, the upper die knife 24 can be reciprocated up and down, thereby improving the die-cutting efficiency. Finally, when the die cutting is completed, since the knife groove 30 is a hollow structure, after the die cutting by the upper die knife 24, the groove 23 will be distributed with chips falling through the knife groove 30. At this time, the staff turns on the first motor 3, and the first motor 3 drives the first screw 4 to rotate. The rotation of the first screw 4 causes the first auxiliary plate 5 to drive the moving plate 6 to move, so that the chips are uniformly moved to the end of the groove 23. Then the second motor 8 is turned on, and the second motor 8 drives the second screw 9 to rotate. The rotation of the second screw 9 causes the second auxiliary plate 10 to drive the push plate 6 to move. The plate 11 moves, and the movement of the push plate 11 drives the chips on one side of the movable plate 6 to be pushed to the through hole 22, and the through hole 22 is an inclined slope, which is convenient for the chips to be discharged from the through hole 22, and the reciprocating movement of the push plate 11 can continuously clean and discharge the chips. At the same time, when the push plate 11 pushes and discharges the chips, the movable plate 6 is still in the position after the movement, so that the area moved by the push plate 11 is a closed area, avoiding the situation where the chips cannot be discharged, improving the cleaning efficiency, and making the cleaning effect more thorough. After the cleaning is completed, the movable plate 6 and the push plate 11 can be reset to facilitate subsequent cleaning.
[0044] In summary, the utility model provides a die-cutting mechanism of a bag making machine, including a bottom plate, a groove is provided inside the bottom plate, a lower die seat is provided on the top surface of the groove, a first driving member is penetrated inside the groove, a movable plate is sleeved on the first driving member, and the movable plate is driven to move by the first driving member to realize unified processing of chips, a second driving member is also provided at the end of the groove, a push plate is sleeved on the second driving member, and the chips are repeatedly discharged from the groove by the push plate to improve cleaning efficiency, a vertical plate is provided on one side of the bottom plate, a third driving member is provided on the vertical plate, the third driving member penetrates the interior of the vertical plate and an eccentric member is provided at the end, an upper die knife group is abutted at the bottom of the eccentric member, the upper die knife group is moved downward by the third driving member and die cutting is realized, one side of the upper die knife group is connected to the vertical plate by a reset component, the reset component facilitates the reset of the upper die knife group to realize continuous multiple die cutting, two groups of through holes connected to the groove are provided on the bottom plate, and the chips are conveniently discharged through the through holes. In summary, the utility model drives the rotating shaft to rotate by the third motor to realize the rotation of the eccentric piece, thereby realizing the downward movement of the upper die knife group. The upper die knife group improves the stability of die cutting while performing die cutting. The first motor drives the first screw to rotate, so that the movable plate can move the chips after die cutting to the end of the groove in a unified manner, thereby avoiding the chips falling in multiple corners in the groove and causing incomplete cleaning. Then, the second motor drives the second screw to rotate, so that the push plate can push the chips uniformly moved by the movable plate, so that the chips can be discharged from the through hole. Since there are two groups of through holes, when the push plate is reset, the chips that were not cleaned up for the first time can also be pushed to another group of through holes, thereby realizing the cleaning of the chips through the reciprocating movement of the push plate. At the same time, the connection between the movable plate and the groove forms an enclosed space, so that the push plate can clean all the chips in the space, thereby improving the cleaning efficiency.
