[0002] A slitter is an important mechanical device, mainly used for slitting raw materials such as wide-width paper, mica tape or film into multiple narrow-width materials. This device has a wide range of applications in the fields of papermaking machinery, wire and cable mica tape, and printing and packaging machinery.

[0003] Existing slitters on the market cannot integrate the simultaneous adjustment of the distances between multiple cutting knives and the independent adjustment of the distances of each cutting knife separately. This limitation is particularly prominent for slitting operations that need to process materials of various widths or thicknesses.

[0004] Different materials may require different cutting spacings. When the distances of multiple cutting knives cannot be adjusted simultaneously, operators must adjust them one by one when synchronous adjustment of the positions of multiple cutting knives is required, which increases the possibility of errors and reduces the cutting accuracy.

[0005] In view of this, this application is specifically proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: a slitting structure of a slitter, the support table is provided with a plurality of cutting knives with adjustable positions, and the support table is also provided with an adjusting mechanism for adjusting the positions between two adjacent cutting knives;

[0025] The adjusting mechanism includes a hollow adjusting rod 4 rotatably installed on the support table 1. A flexible airbag 5 is installed on the outer wall of the hollow adjusting rod 4. A cylindrical cam 6 is sleeved outside the flexible airbag 5. An activity groove 7 is formed on the surface of the cylindrical cam 6. A fixed slide rail 9 is fixedly installed on the support table 1. A follower rod 10 is slidably installed inside the fixed slide rail 9. One end of the follower rod 10 is inserted into the activity groove 7, and the other end of the follower rod 10 is fixedly connected to the cutting knife 11. An air delivery hose 13 fixedly communicated with each flexible airbag 5 is inserted into the hollow adjusting rod 4. A valve 14 is arranged on the air delivery hose 13;

[0026] By controlling the air delivery hose 13 through the opening and closing of the valve 14, the air delivery hose 13 can conveniently control the inflation and deflation of the flexible airbag 5. The sliding design of the fixed slide rail 9 and the follower rod 10 ensures the stability of the cutting knife 11 during the movement process. By using the cooperation of the cylindrical cam 6 and the follower rod 10, and the design of the activity groove 7, the precise control of the position of the cutting knife 11 can be realized, and the operation accuracy is improved.

[0027] Refer to Figures 1-2 As shown, a blower 15 is fixedly installed on the support table 1, and the blower 15 is connected to a plurality of air delivery hoses 13;

[0028] The blower 15 is arranged at one end of the air delivery hose 13 and is efficiently connected to a plurality of air delivery hoses 13, so that the blower 15 can simultaneously deliver gas to a plurality of flexible airbags 5, greatly improving the work efficiency.

[0029] Refer to Figure 4 As shown, a sliding block 16 is slidably installed inside the activity groove 7, and the end of the follower rod 10 away from the cutting knife 11 is fixedly connected to the sliding block 16;

[0030] Furthermore, extension chucks are installed at both the left and right ends of the sliding block 16, and the extension chucks are installed inside the activity groove 7, so that the follower rod 10 can only perform translational motion, realizing the stability during work.

[0031] Refer toFigure 2 As shown, a limiting plate 8 is fixedly installed on the outer wall of the hollow adjusting rod 4, and the limiting plate 8 is located between two adjacent cylindrical cams 6;

[0032] The limiting plate 8 located between two adjacent cylindrical cams 6 can limit the rotation range of the hollow adjusting rod 4, prevent it from rotating excessively and causing the internal gas transmission hose 13 to be twisted and rubbed, avoid damage to the gas transmission hose 13, ensure normal operation and extend the service life.

[0033] Refer to Figure 2 As shown, a runner 12 is fixedly installed at one end of the hollow adjusting rod 4, and an opening for the gas transmission hose 13 to pass through is provided through the center of the runner 12;

[0034] The opening at the center of the runner 12 enables the gas transmission hose 13 to pass through smoothly, ensuring that gas can be transmitted smoothly through the gas transmission hose 13, reducing the resistance during gas transmission, improving the gas transmission efficiency, and at the same time avoiding twisting or folding of the gas transmission hose 13 during transmission, ensuring the stability of gas transmission.

[0035] Refer to Figure 2 As shown, a sliding opening is provided on the fixed slide rail 9, and the follower rod 10 is slidably connected inside the sliding opening;

[0036] The sliding opening provides a stable and precise sliding path for the follower rod 10. The movement of the follower rod 10 inside the sliding opening is restricted and guided, thus ensuring the stability and accuracy of its movement trajectory and reducing the errors caused by free movement.

[0037] Refer to Figure 4 As shown, the movable groove 7 is spirally provided on the outer wall of the cylindrical cam 6, and the depth of the movable groove 7 is 2 cm to 4 cm;

[0038] The spiral design of the movable groove 7 can continuously and smoothly guide the movement of the follower rod 10, so that when the follower rod 10 follows the rotation of the cylindrical cam 6, it can perform continuous and orderly linear movement along the movable groove 7, thereby realizing efficient and precise movement transmission.

[0039] Refer to Figure 3 As shown, the flexible airbag 5 is coated and fixed on the outer wall of the hollow adjusting rod 4. The material of the flexible airbag 5 is rubber, and anti-slip patterns are integrally formed on the outer surface of the flexible airbag 5;

[0040] The anti-slip patterns can increase the friction coefficient on the surface of the flexible airbag 5, making it difficult for the flexible airbag 5 to slide or shift when it contacts the cylindrical cam 6.

[0041] Working principle: The paper roll is installed on the paper roll shaft, and the paper is conveyed through the fixed rod 2 and the conveying roller 3. The blower 15 is turned on, and the gas enters the flexible airbag 5 through the valve 14, causing it to expand and closely fit on the inner wall of the cylindrical cam 6. The runner 12 is manually rotated to drive the cylindrical cam 6 to rotate, and the movable slot 7 drives the follower rod 10 to move parallelly, thereby adjusting the position of the cutter 11. The motor drives the conveying roller 3 to rotate, moving the paper forward and cutting it when it contacts the cutter 11;

[0042] If you want to adjust the position of a certain cutter 11 alone, just open the valve 14 on the air supply hose 13 connected to the corresponding flexible airbag 5 to make the flexible airbag 5 expand and fit on the inner wall of the cylindrical cam 6. By rotating the runner 12 to make the cylindrical cam 6 perform a rotational motion, the position of this cutter 11 can be adjusted alone, realizing flexible and precise control of the position of the cutter 11, and improving the efficiency and precision of paper cutting.
