[0031] Embodiment

[0032] The following will further describe the present utility model in conjunction with the drawings.

[0033] As Figure 1 shown, the film slitting machine for achieving precise cutting provided in this embodiment includes:

[0034] The slitting frame 1 is provided with a unwind roller 2 and a winding roller 3 on both sides respectively, and the unwind roller 2 and the winding roller 3 are connected to a driving motor;

[0035] The tool holder 4 is horizontally connected to the slitting frame 1, and the tool holder 4 is in the form of a rack. A scale line is provided on the side of the tool holder 4 without engaging teeth;

[0036] The cutter holder 5, a plurality of cutter holders 5 are connected to the side of the tool holder 4 provided with engaging teeth, and an indicating line is provided on the edge of the cutter holder 5;

[0037] The cutting knife 6 is detachably connected to the cutter holder 5, and the cutting knife 6 is located above the film 8.

[0038] The working principle and beneficial effects of the present utility model are as follows:

[0039] The film slitting machine for realizing precise cutting provided in this embodiment is adjusted according to the different numbers and intervals of the strips to be slit when slitting the film. First, the corresponding number of cutting knives 6 are installed on the cutter holders 5 and fixed. Secondly, the positions of each cutter holder 5 are adjusted respectively so that the cutting knives 6 can be arranged at a preset interval; a scale line is provided on the tool holder 4, and an indicating line is provided on the cutter holder 5. The position where the indicating line is directly opposite to the scale line is the position of the current cutting knife 6; then the film 8 on the unwind roller 2 is passed under the cutting knife 6 and wound on the winding roller 3; finally, the driving motors of the unwind roller 2 and the winding roller 3 are started to drive the film 8 to move, and it is slit into strip-shaped films with a preset width under the action of the cutting knife 6.

[0040] Through the above structural design, a plurality of independently arranged cutter holders 5 are provided on the tool holder 4. Each cutter holder 5 can be adjusted separately and accurately adjusted according to the positions of the indicating line and the scale line, which can meet the requirements of different-width slitting and cutting, improve the cutting accuracy, and improve the quality of the film product; the cutting knife 6 is detachably arranged, and the number of cutting knives 6 can be adjusted according to the number of strips, which can meet the requirements of different-number slitting and cutting, improve the adjustable range of the slitting machine, and has better practicability.

[0041] As Figure 1 shown, in one embodiment, two lifting hydraulic cylinders 7 are symmetrically arranged at the front and rear of the top of the slitting frame 1, and the rod parts of the lifting hydraulic cylinders 7 extend vertically downward and are connected to the end of the tool holder 4.

[0042] The working principle and beneficial effects of the above technical solution are as follows:

[0043] When cutting the film 8 with the cutting knife 6, start the lifting hydraulic cylinder 7 to adjust the cutting knife 6 to a preset height, so that the cutting knife 6 contacts the film 8 and maintains a certain pressure to ensure the effective progress of the cutting process and avoid cutting breakpoints caused by incomplete contact between the cutting knife 6 and the film 8.

[0044] As Figures 2-4As shown, in one embodiment, the cutter holder 5 includes: a sliding seat body 11, an adjusting gear 12, a rotating shaft 13, and a transmission gear 14. The sliding seat body 11 is slidably disposed on the tool rest 4, and a transmission cavity is provided on one side of the sliding seat body 11; the adjusting gear 12 is connected to the bottom end of the sliding seat body 11 through the rotating shaft 13; the transmission gear 14 is connected to one end of the rotating shaft 13 extending into the transmission cavity, and the transmission gear 14 is meshed and connected with the engaging teeth of the tool rest 4.

[0045] On the other side of the sliding seat body 11, a support plate 15 is connected.

[0046] The working principle and beneficial effects of the above technical solution are as follows:

[0047] When adjusting the position of the cutter holder 5, rotate the adjusting gear 12 below the tool rest 4. The adjusting gear 12 drives the transmission gear 14 to rotate through the rotating shaft 13. The transmission gear 14 is in meshing transmission with the engaging teeth on the tool rest 4, driving the sliding seat body 11 to slide along the tool rest 4, thereby realizing the rapid adjustment of the horizontal position of the cutter holder 5. The adjustment method is simple and easy to control and implement.

[0048] As Figure 2 、 3 shown, in one embodiment, the cutter holder 5 further includes: a limiting plate 16. The limiting plate 16 is hinged to the middle of the sliding seat body 11, and a torsion spring is provided at the hinge. One end of the limiting plate 16 close to the support plate 15 is bent.

[0049] A through hole 17 is provided on the sliding seat body 11. The bent end of the limiting plate 16 passes through the through hole 17 and is clamped between adjacent engaging teeth on the tool rest 4.

[0050] The working principle and beneficial effects of the above technical solution are as follows:

[0051] When the limiting plate 16 is provided on the cutter holder 5, when adjusting the cutter holder 5, press one end of the limiting plate 16 close to the adjusting gear 12. The middle of the limiting plate 16 is hinged to the sliding seat body 11. Therefore, the limiting plate 16 rotates and stores energy in the torsion spring. The bent end of the limiting plate 16 moves out of the through hole 17, releasing the locking between the sliding seat body 11 and the tool rest 4. The sliding seat body 11 can move freely, and then the position of the cutter holder 5 can be adjusted. When the cutter holder 5 is adjusted to the preset position, release the limiting plate 16. The limiting plate 16 quickly resets under the action of the torsion spring. The bent end of the limiting plate 16 passes through the through hole 17 and is clamped between adjacent engaging teeth on the tool rest 4 again, limiting the sliding seat body 11 again. Through the above structural design, the limiting plate 16 is used to lock the position of the cutter holder 5, effectively preventing the cutter 6 from shifting during the cutting process and improving the accuracy of film slitting.

[0052] As Figure 2 、 3As shown, in one embodiment, the cutter holder 5 further includes: a first jacket 21 and a second jacket 22. The arc-shaped wall of the first jacket 21 is connected to the support plate 15. The second jacket 22 is disposed on the other side of the first jacket 21, and the first end of the second jacket 22 is hinged to the first end of the first jacket 21. A clamping space for the rod portion of the cutter 6 is formed by surrounding the first jacket 21 and the second jacket 22.

[0053] The second end of the first jacket 21 is connected with a screw rod 23 and the screw rod 23 is horizontally arranged; the screw rod 23 passes through the second jacket 22 and is locked by a nut 24.

[0054] A slot 25 for the screw rod 23 to pass through is provided at the second end of the second jacket 22.

[0055] The working principle and beneficial effects of the above technical solution are as follows:

[0056] When the cutter holder 5 is in use, rotate the second jacket 22 to separate it from the first jacket 21, place the rod portion of the cutter 6 into the first jacket 21, then rotate the second jacket 22 to clamp the rod portion of the cutter 6 between the first jacket 21 and the second jacket 22; move the screw rod 23 into the slot 25, and then tighten the nut 24 on the screw rod 23 outside the second jacket 22 to lock the first jacket 21 and the second jacket 22, thus completing the fixation of the cutter 6. When disassembling, unscrew the nut 24 from the screw rod 23, rotate the second jacket 22, and take out the cutter 6. Through the above structural design, the cutter 6 is clamped and fixed by the jacket, which is convenient and fast for disassembly and assembly, facilitates the adjustment of the number of cutters 6, and can also be quickly replaced when the cutter 6 is damaged.

[0057] In one embodiment, anti-slip pads are provided on the inner walls of the first jacket 21 and the second jacket 22.

[0058] The working principle and beneficial effects of the above technical solution are as follows:

[0059] With the setting of the anti-slip pads, the rod portion of the cutter 6 is connected more tightly to the jacket, improving the installation stability of the cutter 6.
