[0027] The adjustable cutting structure for bag making machines disclosed in this utility model is mainly applied to bag making machine scenarios.

[0028] Reference Figures 1 to 8An adjustable cutting structure for a bag-making machine includes: a base plate 1, a mounting plate 2 fixedly connected to the top of the base plate 1, a winding roller 3 provided on one side of the mounting plate 2, a cutting table 4 and a fixing frame 5 fixedly connected to the top of the base plate 1 respectively, a mounting frame 6 provided inside the fixing frame 5, a slot 7 opened on one side of the mounting frame 6, a cutter 8 slidably connected at equal intervals inside the mounting frame 6, a connecting plate 9 fixedly connected to one side of the mounting frame 6, a first sliding rod 10 slidably connected inside the connecting plate 9, and a bottom of the first sliding rod 10 fixedly connected to... A pressure wheel 11 is fixedly connected to the first slide rod 10. A first spring 12 is provided on the outer side of the first slide rod 10. A keyway is provided inside the first slide rod 10. A flat key is provided inside the connecting plate 9. A connecting block 13 is fixedly connected to the top of the mounting frame 6. A baffle 14 is rotatably connected to one side of the connecting block 13. One side of the baffle 14 is slidably connected to one side of the cutter 8. A limit component is provided on one side of the mounting frame 6. The limit component is used to fix the baffle 14. A drive component is provided inside the mounting frame 6. The drive component is used to drive the mounting frame 6 to move.

[0029] The limiting component includes a first side plate 16, which is fixedly connected to one side of the mounting frame 6 at equal intervals. A second slide rod 17 is fixedly connected to the bottom of the first side plate 16. A retaining plate 18 is slidably connected inside the second slide rod 17. A limiting groove 15 is opened on one side of the baffle 14. One side of the retaining plate 18 abuts against one side of the inner wall of the limiting groove 15. A second spring 19 is provided on the outer side of the second slide rod 17.

[0030] A second side plate 20 is fixedly connected to one side of the mounting frame 6. A third slide rod 21 is slidably connected inside the second side plate 20. A locking block 22 is fixedly connected to the bottom of the third slide rod 21. One side of the locking block 22 is slidably connected to one side of the mounting frame 6. A slot 23 is provided on the top of the locking plate 18. One side of the locking block 22 abuts against one side of the inner wall of the slot 23. A third spring 24 is provided on the outer side of the third slide rod 21.

[0031] Both one side of the card plate 18 and one side of the card block 22 are provided with a slope;

[0032] The top of the mounting frame 6 is provided with a first telescopic rod 25. The bottom of the first telescopic rod 25 extends into the interior of the mounting frame 6 and is fixedly connected to a pressing plate 26. The bottom of the pressing plate 26 abuts against the top of one of the cutters 8.

[0033] In the above technical solution, considering the problem of incomplete cutting caused by wear of the cutter blade due to prolonged cutting, resulting in a gap between the cutter blade and the cutting table, the specific operation is as follows: Multiple sets of cutters 8 are stacked vertically. Using the limiting component, the clamping plate 18 is lifted upwards, causing it to misalign with the limiting groove 15. Then, the baffle 14 is rotated upwards, and the third sliding rod 21 is pulled to allow the clamping block 22 to exit the clamping groove 23. This allows the clamping plate 18 to be rotated, opening the groove 7. The entire set of cutters 8 is then placed into the mounting frame 6, so that the blade head of the bottom cutter 8 extends from the bottom of the mounting frame 6. The first telescopic rod 25 is used to move the pressing plate 26 downwards inside the mounting frame 6, pressing down on the cutter 8 to prevent it from moving. Then, the clamping plate 14 is... Turning back, the corner of the card plate 18 will contact the inclined surface of the card block 22, pushing the card block 22 up. The third spring 24 is compressed until the card plate 18 is in contact with one side of the mounting frame 6. Under the action of the third spring 24, the card block 22 enters the card slot 23, fixing the card plate 18. Next, turn the baffle 14 down, and the corner of the limiting groove 15 will contact the inclined surface of the card plate 18. Continue to apply force, and then push the card plate 18 up. The second spring 19 is compressed until the card plate 18 can enter the limiting groove 15. The baffle 14 is vertical and blocks the cutter 8. Under the action of the second spring 19, the card plate 18 moves downward and abuts against the limiting groove 15, fixing the baffle 14. Then, the drive assembly drives the mounting frame 6 to move downward, and the cutter 8 cuts the plastic bag. When the bottom cutter wears out and needs replacement, simply retract the first telescopic rod 25 to move the pressing plate 26 upward, then lift the second-to-last cutter 8 through the gap in the slot 7, and pull the bottom cutter 8 out from the bottom of the baffle 14. Using multiple sets of cutters 8 allows for gradual replacement of worn or damaged cutter sets, reducing equipment downtime and improving the flexibility of cutter 8 replacement. The limiting component not only allows for quick fixing and opening of the baffle 14, facilitating the storage of the cutters 8 in the mounting frame 6, but also prevents positional shifts or movement during cutting, thus ensuring cutting accuracy.

[0034] Reference Figures 1 to 8 In a preferred embodiment, the drive assembly includes a fixed plate 27 disposed inside the fixed frame 5. A second telescopic rod 28 is disposed on the top of the fixed plate 27, and the bottom of the second telescopic rod 28 is fixedly connected to the top of the mounting frame 6. Movable blocks 29 are fixedly connected at equal intervals on the top of the fixed plate 27, and fixed blocks 30 are fixedly connected at equal intervals on the top of the fixed frame 5. A lead screw 31 and a mounting rod 32 are respectively disposed on one side of the fixed block 30. The outer side of the lead screw 31 is threadedly connected to the inside of one of the movable blocks 29, and the mounting rod 32 is slidably connected to the inside of the other movable block 29. A motor 33 is disposed on the top of the fixed frame 5, and one end of the output shaft of the motor 33 is fixedly connected to one end of the lead screw 31.

[0035] In the above technical solution, considering the problem that the cutting device of the bag making machine cannot move the cutting position back and forth or quickly adjust the cutter, the specific operation is as follows to solve this problem: the motor 33 is started to drive the lead screw 31 to rotate, and the limiting effect of the mounting rod 32 is used to make the movable block 29 and the fixed plate 27 move back and forth, thereby adjusting the position of the cutter 8 as needed. Then, the second telescopic rod 28 is started to drive the mounting frame 6 to move downward, and at the same time, the cutter 8 inside it will cut the plastic bag. By using the drive component, the position of the cutter 8 can be moved back and forth precisely to meet the cutting requirements of different sizes or positions.

[0036] Working principle: In use, multiple sets of cutters 8 are stacked vertically. The limiting component lifts the clamping plate 18 upwards, causing it to misalign with the limiting groove 15. Then, the baffle 14 is rotated upwards, and the third sliding rod 21 is pulled to disengage the clamping block 22 from the clamping groove 23. This allows the clamping plate 18 to rotate, opening the groove 7. The entire set of cutters 8 is then placed into the mounting frame 6, with the blade head of the bottom cutter 8 extending from the bottom of the mounting frame 6. The first telescopic rod 25 moves the pressing plate 26 downwards inside the mounting frame 6, pressing down on the cutter 8 to prevent it from moving. The clamping plate 18 is then rotated back, causing its corners to contact the inclined surface of the clamping block 22, pushing it upwards. The third spring 24 is compressed until the clamping plate 18 is flush with one side of the mounting frame 6. Under the action of the third spring 24, the clamping block 22 enters the clamping groove. In slot 23, fix the card plate 18. Then, rotate the baffle 14 down. The corner of the limiting slot 15 will contact the inclined surface of the card plate 18. Continue to apply force and push the card plate 18 up. The second spring 19 is compressed until the card plate 18 can enter the limiting slot 15. The baffle 14 is vertical and blocks the cutter 8. Under the action of the second spring 19, the card plate 18 moves downward and abuts against the limiting slot 15, fixing the baffle 14. Then, start the motor 33 to drive the lead screw 31 to rotate. With the limiting effect of the mounting rod 32, the movable block 29 and the fixed plate 27 move back and forth. Adjust the position of the cutter 8 as needed. Then, start the second telescopic rod 28 to drive the mounting frame 6 to move downward. At the same time, the cutter 8 inside will cut the plastic bag.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
