The diamond hinge includes a plurality of connecting bars 4 hinged together through a plurality of end shafts and a plurality of central shafts. A plurality of slitting ring knives are arranged on both the slitting main shaft 2 and the slitting auxiliary shaft 3. A plurality of limiting mechanisms adapted to the slitting ring knives on the slitting main shaft 2 and the slitting auxiliary shaft 3 are arranged on a plurality of central shafts and a plurality of end shafts on one side. The slitting main shaft 2 is rotatably connected to the frame 1, and guide roller sets 21 rotatably connected to the frame 1 are arranged on both sides of the slitting main shaft 2. It also includes an equal-spacing adjustment driving mechanism for adjusting the distance between the central shafts at both ends, and a rotating mechanism for driving the diamond hinge to rotate around the slitting main shaft 2.
[0025] Specifically, the equal-spacing adjustment driving mechanism includes an adjustable-distance guide rail 12. A bidirectional screw 13 is rotatably connected to the adjustable-distance guide rail 12. Two groups of L-shaped sliders 11 that are symmetrically threadedly connected to the bidirectional screw 13 and are in guiding and sliding fit with the adjustable-distance guide rail 12 are arranged. The two central shafts at the ends are respectively connected to the two L-shaped sliders 11, and both L-shaped sliders 11 are in guiding and sliding fit with the slitting main shaft 2. By rotating the bidirectional screw 13 clockwise or counterclockwise, the two L-shaped sliders 11 can be driven to move towards the middle or away from the middle, so that the two central shafts at the ends can be driven to move towards the middle or towards both sides, so that the diamond hinge can perform a telescopic operation, so that the plurality of slitting ring knives on the slitting main shaft 2 and the slitting auxiliary shaft 3 can be adjusted as a whole at equal intervals.
[0026] Specifically, the rotating mechanism includes two groups of switching adjustment driving cylinders 19 arranged on both sides of the frame 1. A guide track 16 is in sliding fit at the plurality of end shafts at the other end. A guide chute 17 for guiding and sliding fit with the end shafts is provided on the guide track 16. Guide sleeves 20 are in vertical sliding fit at both ends of the guide chute 17. The switching adjustment driving cylinder 19 is hinged between the frame 1 and the guide sleeve 20. By the switching adjustment driving cylinder 19, the output shaft of the switching adjustment driving cylinder 19 is extended or shortened. Through the cooperation of the guide sleeve 20 and the guide chute 17, the whole diamond hinge can be driven to perform an inclined rotation.
[0027] Specifically, the slitting ring knife includes a slitting ring blade 8 with a clamping shaft sleeve 9 fixedly installed in the middle. Embedded ring grooves 10 are symmetrically provided on both sides of the slitting ring blade 8. The limiting mechanism includes a fixed seat 6 symmetrically and fixedly connected with two groups of guide rings 7. The guide rings 7 are in rotational and sliding fit with the embedded ring grooves 10. The clamping shaft sleeve 9 is in guiding and sliding fit with the slitting main shaft 2. The fixed seat 6 is fixedly connected with the central shaft through an extension rod 5. Further, the slitting main shaft 2 and the slitting auxiliary shaft 3 have the same specifications and are both in guiding and sliding fit with the clamping shaft sleeve 9. Further, the extension rod 5 is detachably connected to the fixed seat 6 or the central shaft or the end shaft through bolts, which is convenient for later maintenance and repair.
[0028] Specifically, the machine frame 1 further includes a slitting drive motor 18 for driving the slitting main shaft 2 to rotate. Further, the slitting drive motor 18 is fixedly installed on the machine frame 1. Starting the slitting drive motor 18 facilitates driving the slitting main shaft 2 to rotate, so that the slitting ring knives on multiple slitting main shafts 2 can rotate to slit the packaging film.
[0029] Specifically, a driving member for driving the bidirectional screw 13 to rotate is provided on the distance-adjusting guide rail 12. The driving member includes a distance-adjusting motor 14 fixedly installed on the distance-adjusting guide rail 12. The output shaft of the distance-adjusting motor 14 is in transmission connection with the bidirectional screw 13 through a transmission assembly 15. Further, the transmission assembly 15 can be set in a transmission form such as a sprocket chain or a belt pulley. Starting the distance-adjusting motor 14 to make the output shaft of the distance-adjusting motor 14 rotate clockwise or counterclockwise, through the transmission cooperation of the transmission assembly 15, the bidirectional screw 13 can be driven to rotate clockwise or counterclockwise.
[0030] During use, according to the width of the slitting of the plastic bag film, the distance between the overall multiple slitting ring knives on the slitting main shaft 2 and the slitting auxiliary shaft 3 is adjusted by the equal-spacing adjusting drive mechanism. Then, the plastic bag film is sequentially introduced from one side of the guide roller group 21 and closely attached to the slitting main shaft 2 and then led out from the other guide roller group 21. Then, the inclination angle of the diamond hinge is adjusted by the rotating mechanism and the slitting auxiliary shaft 3 is closely attached to the slitting plastic film located between the slitting main shaft 2 and the guide roller group 21 at the rear side, ensuring that both the slitting main shaft 2 and the slitting auxiliary shaft 3 are involved in the slitting operation. When the slitting width is large, the rotating mechanism can drive the slitting auxiliary shaft 3 to rotate away from the slitting position. Then, the overall multiple slitting ring knives are adjusted by the equal-spacing adjusting drive mechanism, and the multiple slitting ring knives on the slitting main shaft 2 are equally spaced to the required width. Then, repeating the above operations can perform a wider slitting operation.
