Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slitting machine, in particular to a slitting machine with segmented combined knife roll and self-adaptive material pressing structure. BACKGROUND

[0002] The slitting machine is a special mechanical equipment for cutting paper, film, non-woven fabric, aluminum foil and other wide roll materials according to the required width and length, which realizes the accurate cutting, arrangement and rewinding of the roll material through the cooperation of the knife roll, material pressing, feeding and control system, and is widely used in printing, packaging, plastic and textile industries, and is the core equipment of the roll material processing production line. The existing slitting machine adopts an integral knife roll structure, and the cutter and the knife shaft are integrated. When a single cutter is worn or damaged, the entire device needs to be disassembled and replaced, which takes a long time to maintain and cannot adjust the cutter position for different cutting widths. In addition, the integral knife roll is difficult to adapt to flexible production requirements of multiple specifications and small batches due to high processing and replacement costs, and has poor flexibility. The existing cutter of the slitting machine is of a fixed structure, and the rotational inertia and dynamic balance state cannot be adjusted. When cutting at high speed, vibration and deflection may occur due to sudden load changes, resulting in rough edges, cutter vibration and other problems. The traditional counterweight is a fixed weight block, which cannot be adjusted in weight and position online, and the dynamic balance correction is complicated, which affects the cutting accuracy and cutter life. The upper and lower cutters of the existing slitting machine adopt the same speed synchronous cutting method, and the cutting process is mainly extrusion, which may cause rough edges, wire drawing or indentation of the film, paper and other materials. In addition, the same speed cutting is highly dependent on the cutter accuracy, and the cutting quality decreases rapidly after wear. The cutting effect cannot be optimized by adjusting the speed, which cannot meet the high-precision cutting requirements. Finally, the existing slitting machine uses a mechanical locking or ordinary elastic element pressing structure for the material pressing roller. Once the position is fixed, it is inconvenient to adjust, and the self-adaptive buffer effect is single. The conventional elastic mechanism cannot accurately detect the displacement, and the pressing force and floating stroke cannot be accurately controlled, which may cause unstable pressing, deviation and wrinkling, and cannot meet the requirements of high-precision self-adaptive cutting.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The embodiments of this invention will now be described according to its overall structure.

[0020] Example 1:

[0021] Please see Figures 1-3 The present invention provides a slitting machine with a segmented combined cutter roller and an adaptive pressing structure, comprising a slitting machine body 1, a segmented mechanism 2 provided on the upper part of the slitting machine body 1, a pressing roller 3 provided at the front end of the top of the slitting machine body 1, and an adaptive mechanism 4 fixedly connected to the front sides of both the left and right ends of the slitting machine body 1.

[0022] The segmented mechanism 2 includes a cutter shaft 21. Two sets of cutter shafts 21 are provided on the upper part of the slitting machine body 1. The two sets of cutter shafts 21 are arranged in an asymmetrical manner with the upper and lower sides facing each other. Cutting blades 22 are fixedly connected to the outer walls of the cutter shafts 21. Four sets of adjustment mechanisms 23 are provided equidistantly on the sides of the cutting blades 22. The cutting blades 22 facilitate the slitting operation of the roll material.

[0023] The cutter shaft 21 has a connector 24 fixedly connected to the right end inside, and a strong magnetic block 25 fixedly connected to the right end of the connector 24. The strong magnetic block 25 is electrically connected to an external current output device. The strong magnetic block 25 is magnetically attracted to the mating block 26. The cutter shaft 21 is segmented, specifically composed of three sets of mounting rollers that are inserted on the left and right. The right end of the rightmost mounting roller of the cutter shaft 21 is rotatably connected to the speed regulating mechanism 27. The strong magnetic block 25 is easy to be firmly magnetically attracted to the mating block 26, realizing the coaxial locking and synchronous transmission of the three sets of segmented mounting rollers.

[0024] The connector 24 consists of a fixed plate fixedly connected to the right end of the cutter shaft 21, a micro motor fixedly connected to the back of the fixed plate, a rotating rod fixedly connected to the front output shaft of the micro motor and rotatably connected to the lower front end of the fixed plate, a swing rod rotatably connected to the front end of the rotating rod, a mounting base rotatably connected to the outer wall of the swing rod, and a limiting frame fixedly connected to the bottom end of the cutter shaft 21. A mating block 26 is fixedly connected to the left end of the cutter shaft 21. The mounting base of the connector 24 is fixedly connected to the strong magnetic block 25, and the outer wall of the strong magnetic block 25 is slidably connected to the limiting frame of the connector 24.

[0025] The working principle of a slitting machine with segmented combined cutter rollers and an adaptive pressing structure based on Embodiment 1 is as follows: First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation. Secondly, when the cutter 22 needs to be assembled, the micro motor of the connector 24 drives the rotating rod of the connector 24 to rotate on the fixed plate of the connector 24. The rotating rod of the connector 24 drives the swing rod of the connector 24 to swing, which in turn pushes the strong magnetic block 25 fixed to the mounting base of the connector 24 to slide along the limiting frame of the connector 24, so that the strong magnetic block 25 is precisely aligned with the mating block 26 at the left end of the adjacent mounting roller. Then, the strong magnetic block 25 is energized by the external current output device, so that it generates a strong magnetic attraction force and is firmly magnetically attracted to the mating block 26, realizing the coaxial locking and synchronous transmission of the three-section mounting rollers. During use, the slitting machine body 1 first outputs power through the speed regulating mechanism 27 to drive the rightmost section mounting roller to rotate. The internal right-end connector 24 connects to the adjacent mounting rollers, ultimately driving two sets of vertically opposed and asymmetrically arranged cutter shafts 21 to rotate synchronously. The cutter 22 fixed to the outer wall of the cutter shaft 21 rotates with the shaft to slit the roll material. During the slitting process, the pressure roller 3 at the top front end of the slitting machine body 1 continuously presses the roll material, ensuring slitting accuracy in conjunction with the stable transmission of the cutter shaft 21. When a single set of cutters 22 wears out or needs to be replaced with different slitting specifications, the power supply to the strong magnet 25 of the corresponding segment mounting roller can be cut off, causing it to lose its magnetism. The micro motor of the connector 24 drives the strong magnet 25 to reset, releasing it from the attraction with the mating block 26. The mounting roller and cutter 22 of that segment can be disassembled separately for maintenance or replacement without disassembling the entire cutter shaft, greatly reducing downtime.

[0026] Example 2:

[0027] Please see Figures 4-5The present invention provides a slitting machine with a segmented combined cutter roller and an adaptive pressing structure. Compared with Embodiment 1, this embodiment further includes an adjustment mechanism 23. The adjustment mechanism 23 includes an arc-shaped slide groove 231. Four sets of arc-shaped slide grooves 231 are equidistantly provided on the side of the cutter 22. A first counterweight electromagnetic block 232 is slidably connected to the inner wall of the arc-shaped slide groove 231. The first counterweight electromagnetic block 232 can slide freely along the arc-shaped slide groove 231.

[0028] A buffer pad 233 is glued to the outside of the first counterweight electromagnetic block 232. A plug rod 234 is fixedly connected to the left end of the first counterweight electromagnetic block 232. The plug rod 234 is inserted into the plug hole 235. The plug hole 235 is located on the side of the second counterweight electromagnetic block 236. A buffer pad 233 is glued to the outside of the second counterweight electromagnetic block 236. The buffer pad 233 is convenient for absorbing the impact vibration generated by high-speed operation, and further suppresses the vibration of the cutter 22.

[0029] Both the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236 are electrically connected to an external current output device. When the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236 are energized, they are magnetically attracted to the arc-shaped slide groove 231.

[0030] In this embodiment: When the cutter 22 rotates at high speed with the cutter shaft 21, if dynamic imbalance or vibration occurs, the operator can de-energize the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236 via an external current output device. This causes them to lose their magnetic attraction to the arc-shaped slide groove 231, allowing them to slide freely along the arc-shaped slide groove 231. Based on the imbalance state of the cutter 22, after sliding the first counterweight electromagnetic block 232 to the target position, the second counterweight electromagnetic block 236 can be inserted into the insertion hole 235 on the first counterweight electromagnetic block 232 via the insertion rod 234. The magnetic attraction between the first and second counterweight electromagnetic blocks 232 and 236 creates counterweights of different weights. The counterweight weight can be flexibly adjusted. After adjustment, the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236 are energized through an external current output device, so that they generate a strong magnetic attraction force with the inner wall of the arc-shaped slide groove 231, fixing the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236 in the current position. This completes the online dynamic correction of the rotational inertia and dynamic balance of the cutter 22. At the same time, the buffer pad 233 on the outside of the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236 can absorb the impact vibration generated by high-speed operation, further suppress the vibration of the cutter 22, effectively avoid burrs on the cut, improve the cutting accuracy and the service life of the cutter 22, and adapt to different speeds and cutting conditions.

[0031] Example 3:

[0032] Please see Figure 6The present invention provides a slitting machine with a segmented combined cutter roller and an adaptive pressing structure. Compared with Embodiment 1, this embodiment further includes a speed regulating mechanism 27. The speed regulating mechanism 27 includes a mounting box 271. The right end of the rightmost mounting roller of the cutter shaft 21 is rotatably connected to the left end of the mounting box 271. Motors 272 are fixedly connected to both the upper and lower sides of the right end inside the mounting box 271. The output shaft of the left end of the motor 272 is fixedly connected to a first connecting rod 273, so that the motor 272 can drive the corresponding first connecting rod 273 to rotate.

[0033] A first gear set 274 is provided at the right end of the outer wall of the first connecting rod 273, a second gear set 275 is provided at the center of the outer wall of the first connecting rod 273, and a third gear set 276 is provided at the left end of the outer wall of the first connecting rod 273. The first gear set 274, the second gear set 275, and the third gear set 276 are all composed of two sets of gears of different diameters meshing in the front and rear. The internal center of the rear gear of the first gear set 274, the second gear set 275, and the third gear set 276 is located on the outer wall of the second connecting rod 277, and the left end of the second connecting rod 277 is fixedly connected to the cutter shaft 21. The first gear set 274, the second gear set 275, and the third gear set 276 facilitate differential speed control through the transmission ratio.

[0034] Three sets of first electromagnetic blocks 278 are fixedly connected to the outer walls of the second connecting rod 277 and the first connecting rod 273. The bottom of the mounting box 271 is fixedly connected to the top of the slitting machine body 1. When the first electromagnetic blocks 278 are energized, they are magnetically attracted to the center of the front and rear gears of the first gear set 274, the second gear set 275, and the third gear set 276, respectively. The first electromagnetic blocks 278 are electrically connected to the external current output device. The diameter ratio of the front and rear gears of the first gear set 274 is 1:1.5, the diameter ratio of the front and rear gears of the second gear set 275 is 1:2, and the diameter ratio of the front and rear gears of the third gear set 276 is 1:2.5.

[0035] In this embodiment: When speed adjustment is required, the two sets of motors 272 inside the mounting box 271 drive the corresponding first connecting rod 273 to rotate. The three sets of first electromagnetic blocks 278 on the outer wall of the first connecting rod 273 are powered on and off through an external current output device, thereby achieving magnetic adsorption and engagement with different gear sets. When the upper and lower cutters need to cut at the same speed, the upper and lower first electromagnetic blocks 278 are controlled to adsorb the corresponding gears of the first gear set 274, so that the upper and lower second connecting rods 277 drive the cutter shaft 21 to rotate synchronously at the same speed. When differential cutting is required, the upper and lower first electromagnetic blocks 278 can be controlled to adsorb gear sets with different transmission ratios, such as the upper adsorbing the second gear set 275 and the lower adsorbing the third gear set 276, so that the upper and lower cutter shafts 21 produce a precise speed difference. This is repeated to form a continuous cutting effect and avoid material squeezing and burrs. By switching the electromagnetic adsorption state of different gear sets, the speed difference of the upper and lower cutters 22 can be quickly adjusted online to adapt to the cutting requirements of different materials and thicknesses of rolls. At the same time, the stability of the gear set transmission improves the cutting accuracy and production efficiency.

[0036] Example 4:

[0037] Please see Figures 7-8 The present invention provides a slitting machine with a segmented combined cutter roller and an adaptive pressing structure. Compared with Embodiment 1, this embodiment further includes: an adaptive mechanism 4. The adaptive mechanism 4 includes a mounting frame 41. The mounting frame 41 is fixedly connected to the front side of both the left and right ends of the slitting machine body 1. The center of the mounting frame 41 is fixedly connected to the outer wall of the piston rod 42. A connecting block 43 is fixedly connected to the top of the piston rod 42. A connecting seat 44 is fixedly connected to the top of the connecting block 43. A second electromagnetic block 45 is fixedly connected to both the front and rear ends of the bottom of the connecting block 43. The outer wall of the second electromagnetic block 45 is magnetically attracted to the mounting frame 41.

[0038] The bottom of the second electromagnetic block 45 is fixedly connected to an electric spring 46. Resistance strain gauges 47 are glued to each of the spring wire axes of the electric spring 46 in the ±45° direction. The connecting seat 44 is rotatably connected to the outside of the pressure roller 3. The electric spring 46 is electrically connected to an external power source. The bottom of the electric spring 46 is fixedly connected to the bottom of the mounting bracket 41. The resistance strain gauges 47 are electrically connected to an external control system.

[0039] In this embodiment: When adaptive pressing is required, the power supply to the second electromagnetic block 45 is cut off by an external current output device, releasing the magnetic adsorption. The electric spring 46 and piston rod 42 automatically extend and retract according to the thickness and tension of the roll material, driving the pressing roller 3 to adapt to floating pressing, ensuring that the roll material always adheres to the pressing roller 3. During the extension and retraction process, the deformation signal of the electric spring 46 is collected in real time by the resistance strain gauge 47, accurately detecting the compression amount and movement distance of the electric spring 46, and feeding it back to the external control system. After adjustment, the second electromagnetic block 45 is driven to work by the external current output device, so that the second electromagnetic block 45 is magnetically adsorbed with the mounting bracket 41, realizing the rapid positioning and fixation of the pressing roller 3. Together with the electric spring 46 and piston rod 42, adaptive pressing is achieved, and the movement distance of the electric spring 46 is detected in real time by the resistance strain gauge 47, so that the pressing force and floating stroke are precisely controllable.

[0040] This invention provides an improved slitting machine with a segmented combined cutter roller and an adaptive pressing structure. It features a segmented mechanism 2 and a three-section cutter shaft 21 structure that can be independently disassembled, enabling individual replacement and maintenance of each cutter 22 segment by segment. This significantly reduces downtime and replacement costs. During replacement, the three cutters 22 can independently adjust their blade positions and slitting spacing to adapt to slitting different specifications of roll materials, improving equipment versatility and production efficiency. An adjustment mechanism 23 is provided, with four sets of arc-shaped sliding grooves 231, a first counterweight electromagnetic block 232, and a second counterweight electromagnetic block 236 on the side of the cutter 22. By adjusting the first counterweight electromagnetic block 232 and the second counterweight electromagnetic block 236... The electromagnetic block 236 is powered on and off to achieve online dynamic adjustment of the rotational inertia and dynamic balance of the cutter 22, quickly suppressing vibration and impact, and significantly improving high-speed stability and slitting accuracy. A speed adjustment mechanism 27 is set up to quickly adjust the speed difference between the upper and lower cutters 22 online by switching the electromagnetic adsorption state of different gear sets, adapting to the slitting requirements of rolls of different materials and thicknesses. At the same time, the stability of the gear set transmission improves slitting accuracy and production efficiency. An adaptive mechanism 4 is set up to achieve adaptive clamping through an electric spring 46 and a piston rod 42, and the moving distance of the electric spring 46 is detected in real time by a resistance strain gauge 47, so as to achieve precise and controllable clamping force and floating stroke.
