Description

Technical Field

[0001] This invention relates to the field of slitting machine technology, and in particular to an ultra-narrow snap-on slitting machine. Background Technology

[0002] A snap-on slitting machine is a specialized piece of equipment used for the precision slitting of electrode materials, primarily applied in high-end manufacturing fields such as new energy battery electrodes and flexible circuit substrates. This equipment uses a high-precision circular blade system to slit wide electrode materials into multiple narrow strips. Its core requirements include slitting edge quality, dimensional accuracy, and winding stability. Traditional snap-on slitting machines typically consist of basic modules such as an unwinding mechanism, a web guiding system, a slitting device, and a winding mechanism. Among these, the blade configuration and tension control of the slitting mechanism directly affect the slitting quality of the electrode sheets.

[0003] Currently available snap-on slitting machines often encounter problems such as uneven winding, uneven tension, and material drift when slitting ultra-narrow materials due to the small width of the slits, affecting slitting accuracy and winding quality. Furthermore, debris or metal particles may remain on the surface of the slit material; traditional equipment lacks effective cleaning and adsorption methods, resulting in insufficient cleanliness of the finished product, affecting subsequent processing or applications. Therefore, there is an urgent need for an improved snap-on slitting machine that can stably slit ultra-narrow materials and improve winding quality. Summary of the Invention

[0021] like Figures 1 to 13 As shown, this is an ultra-narrow width snap-on slitting machine of the present invention, used to process wide materials into narrow materials. The ultra-narrow width snap-on slitting machine includes an unwinding mechanism 10, a tape-connecting mechanism 20, a travel correction mechanism 30, a traction mechanism 40, a slitting mechanism 50, a first winding unit 60, and a second winding unit 70 arranged sequentially along the material travel direction. The first winding unit 60 and the second winding unit 70 are symmetrically arranged vertically behind the slitting mechanism 50 to form four independent winding channels. Furthermore, the first winding unit 60 includes a first brush dust removal mechanism 61, a first magnetic adsorption mechanism 62, and a first winding mechanism 63 and a second winding mechanism 64 arranged vertically side-by-side along the material travel direction. The second winding unit 70 includes a second brush dust removal mechanism 71, a second magnetic adsorption mechanism 72, and a third winding mechanism 73 and a fourth winding mechanism 74 arranged vertically side-by-side along the material travel direction.

[0022] The ultra-narrow width snap-on slitting machine of this invention adopts a symmetrical double winding unit design, forming four independent winding channels. Each channel is equipped with an independent brush dust removal mechanism and a magnetic adsorption mechanism to ensure the stability of the ultra-narrow width material during slitting and conveying. After passing through the slitting mechanism 50, the material is split into two, and then further split into four after being processed by the brush dust removal mechanism and the magnetic adsorption mechanism, finally being wound up by the four winding mechanisms. This layout not only improves slitting accuracy but also effectively controls material tension, preventing the ultra-narrow width material from drifting or deviating during high-speed slitting. At the same time, the symmetrical structural design makes the equipment operation more balanced and stable, making it particularly suitable for the production and processing of ultra-narrow width materials such as electrode sheets, which require extremely high slitting accuracy.

[0023] The unwinding mechanism 10 employs an unwinding roller 11. Wide-width material is wound around the outside of the unwinding roller 11. In this embodiment, the unwinding roller 11 uses an air shaft to achieve high-precision positioning and stable clamping of the wide-width material. Additionally, a sensor, specifically an infrared sensor or a laser sensor, is located on the side of the unwinding roller 11, with the sensing end facing the unwinding roller 11 to detect the distance to the wide-width material in real time, thereby obtaining the unwinding speed in real time.

[0024] The joining mechanism 20 includes a joining platform 21, a pressure block 22 located above the joining platform 21, and a pressing cylinder 23 located below the joining platform 21. The telescopic end of the pressing cylinder 23 extends vertically upward through the joining platform 21 and connects to the pressure block 22. The joining platform 21 also has multiple vacuum adsorption holes 24, which are connected to an external negative pressure system. When new and old materials need to be joined, the pressing cylinder 23 pushes the pressure block 22 downward, pressing the material ends onto the joining platform 21. The negative pressure system is activated simultaneously to eliminate air between material layers, ensuring that the joint surface is free of air bubbles.

[0025] The traveling correction mechanism 30 includes a correction sensor 31, a first correction roller 32, and a second correction roller 33. The first correction roller 32 and the second correction roller 33 are arranged side by side above the correction sensor 31. The first correction roller 32 and the second correction roller 33 oscillate according to the detection result of the correction sensor 31 to correct the lateral position of the wide material. The correction sensor 31 continuously monitors the edge position of the material, and its detection signal is processed by a PLC to drive the first correction roller 32 and the second correction roller 33 to oscillate in a coordinated manner, forming a closed-loop control system. The cooperation of the first correction roller 32 and the second correction roller 33 can eliminate lateral deviation during the material's movement.

[0026] The traction mechanism 40 includes an active traction roller 41 and a tension-isolating roller 42 located below the active traction roller 41. A lifting and adjusting cylinder 43 is connected to the bottom of the tension-isolating roller 42. The lifting and adjusting cylinder 43 drives the tension-isolating roller 42 to rise and fall, thereby adjusting the distance between the tension-isolating roller 42 and the active traction roller 41, and thus adjusting the mutual pressure between them. The active traction roller 41 is directly driven by a high-torque servo motor, and its surface is coated with a specially textured layer, ensuring a sufficient coefficient of friction while providing stable conveying power. Simultaneously, when wide materials pass through the traction mechanism 40, they wrap around the active roller 581 at a certain angle, effectively increasing the contact area, preventing material slippage, and allowing for precise tension adjustment through changes in the wrap angle.

[0027] The slitting mechanism 50 includes a front tension adjustment module 51, a slitting module 52, and a rear tension adjustment module 53 arranged along the material feeding direction. The slitting module 52 includes a mounting frame 521, an upper slitting blade assembly 522, and a lower slitting blade assembly 523. The upper and lower slitting blade assemblies 522 and 523 are vertically aligned and installed within the mounting frame 521. The upper and lower slitting blade assemblies 522 and 523 work together to slit wide materials into multiple narrow materials. The front tension adjustment module 51 and the rear tension adjustment module 53 employ a floating roller structure with high-sensitivity sensors to finely adjust the feed tension and discharge tension in real time. The upper and lower slitting blade assemblies 522 and 523 adopt a symmetrically arranged slitting blade assembly structure. The precision-machined mounting frame 521 ensures the alignment accuracy of the upper and lower blade assemblies. Ultra-thin circular blades are used to achieve minimum blade spacing while maintaining sufficient rigidity, making it particularly suitable for slitting ultra-narrow materials.

[0028] Since excess scrap material is generated during the slitting process, the slitting mechanism 50 further includes a guide rod 54, multiple scrap material recycling guide modules 55 slidably connected to the guide rod 54, and a scrap material recycling pipe assembly 59 located below the scrap material recycling guide modules 55. The scrap material recycling guide modules 55 and the scrap material recycling pipe assembly 59 cooperate to realize the introduction and recycling of scrap material. The scrap material recycling guide modules 55 are arranged corresponding to the number and position of the scrap material. In this embodiment, three sets of scrap material recycling guide modules 55 are provided.

[0029] Specifically, the edge material recycling guide module 55 includes a sliding base 56 slidably connected to the guide rod 54, an inlet component 57 disposed above the sliding base 56, and a traction component 58 disposed within the sliding base 56. The traction component 58 is used to traction the edge material generated by slitting, allowing it to pass sequentially through the inlet component 57 and the internal channel of the sliding base 56, and be recycled by negative pressure adsorption from the edge material recycling pipe assembly 59. Furthermore, the sliding base 56 has a working chamber 561 on its inner side, an edge material inlet 562 communicating with the working chamber 561 at the top of the sliding base 56, and an edge material outlet 563 communicating with the working chamber 561 at the bottom of the sliding base 56. The inlet assembly 57 includes a guide roller 571 located above the edge material inlet 562 and an inclined baffle 572 located on the side of the guide roller 571; the traction assembly 58 includes an active roller 581 and a passive roller 582 arranged horizontally side by side in the working chamber 561. The traction assembly 58 also includes a drive motor 583 located on the side wall of the sliding base 56, and the drive motor 583 is drivenly connected to the active roller 581.

[0030] The edge material generated from slitting is first guided by guide roller 571 and then accurately enters edge material inlet 562 under the guidance of inclined baffle 572. The specific angle design of inclined baffle 572 ensures that the edge material is introduced in the best posture, avoiding jamming or drifting. After the edge material enters the working chamber 561 of sliding base 56, the traction assembly 58, composed of active roller 581 and passive roller 582, provides stable conveying power. Drive motor 583 drives active roller 581 to rotate through precision reduction mechanism, forming a reliable clamp with the elastically pressed passive roller 582, ensuring that the edge material passes smoothly through working chamber 561. After the edge material is discharged from edge material outlet 563, it immediately enters the negative pressure adsorption area of ​​edge material recovery pipe assembly 59. The recovery pipe assembly uses an optimized negative pressure airflow to quickly suck the edge material into the recovery system, avoiding edge material accumulation or entanglement of the equipment. The entire recycling process is fully automated and requires no manual intervention, making it particularly suitable for continuous high-speed production environments. The combination of negative pressure recycling and mechanical traction ensures that even ultra-narrow edge materials can be completely recycled, effectively solving the technical problems of edge materials easily tangling and accumulating in traditional equipment.

[0031] In addition, the ultra-narrow width snap-on slitting machine also includes an edge material bin (not shown in the figure), and an edge material recovery pipe assembly 59 is connected to the edge material bin. The edge material recovery pipe assembly 59 includes a horizontally arranged main pipe 591 and branch pipes 592 extending upward from the main pipe 591. The branch pipes 592 are correspondingly arranged with the edge material inlet 562 of the sliding base 56. Multiple edge materials enter the main pipe 591 through different branch pipes 592 and are recovered into the edge material bin.

[0032] The first brush dust removal mechanism 61 and the second brush dust removal mechanism 71 have the same structure. The structure of the first brush dust removal mechanism 61 will be described in detail below, and the description of the second brush dust removal mechanism 71 will be omitted. The first brush dust removal mechanism 61 includes a slide rail 611 and two dust removal units that are symmetrically arranged and slidably connected to the slide rail 611. The dust removal unit includes a sliding seat 612, a telescopic cylinder 614, a rotary motor 615, a brush 616, and a semi-enclosed dust cover 617. The sliding seat 612 is slidably connected to the slide rail 611. The telescopic cylinder 614 is located on the side of the slide rail 611, and the telescopic end of the telescopic cylinder 614 is connected to the sliding seat 612. The rotary motor 615 is fixed to the upper end of the sliding seat 612. The brush 616 is cylindrical and is located above the sliding seat 612 and is driven by the rotary motor 615. The semi-enclosed dust cover 617 is fixed to the upper end of the sliding seat 612 and covers the outside of the brush 616. The opposing surfaces of the two semi-enclosed dust covers 617 each include a mating sidewall 617a, and the top of the semi-enclosed dust cover 617 is provided with a U-shaped notch 617b. The dust removal unit also includes an adsorption tube 618, with a through-hole 613 penetrating the sliding seat 612, and one end of the adsorption tube 618 connected to the through-hole 613. The two symmetrically arranged independent dust removal units allow for flexible adjustment of the working distance according to the material width, adapting to the dust removal needs of materials of different thicknesses. The modular dust cover design forms a completely enclosed working space, effectively preventing dust diffusion and improving dust removal efficiency. The combination of mechanical cleaning by rotating brushes 616 and negative pressure adsorption forms a dual dust removal mechanism, ensuring that dust of different particle sizes can be effectively removed.

[0033] The working process of the first brush dust removal mechanism 61 and the second brush dust removal mechanism 71 is as follows: In the initial state, the two dust removal units are in a separate position, leaving enough space for the material to pass through; when the material enters the dust removal area, the telescopic cylinder 614 pushes the dust removal units to move towards each other, so that the docking sidewalls 617a of the two semi-enclosed dust covers 617 fit tightly together to form a complete sealed cavity. At the same time, the two notches are spliced ​​together to form a material channel, ensuring that the material passes through smoothly while preventing dust from overflowing; the rotating motor 615 drives the brush to rotate at high speed to clean the surface of the material; the dust generated by the cleaning enters the adsorption tube 618 through the perforation 613 on the sliding seat 612 under negative pressure, and is finally collected by the central dust removal system.

[0034] The first magnetic adsorption mechanism 62 has the same structure as the second magnetic adsorption mechanism 72. The first magnetic adsorption mechanism 62 includes a front adsorption module 621 and a back adsorption module 624 respectively disposed on the front and back sides of the narrow material. The front adsorption module 621 includes a first support rod 622 and a first magnetic suction element 623 fixed on the first support rod 622. The back adsorption module 624 includes a second support rod 625 and a second magnetic suction element 626 fixed on the second support rod 625. The front adsorption module 621 and the back adsorption module 624 are used to adsorb iron filings and other debris on the front and back sides of the narrow material to ensure the cleanliness of the electrode surface.

[0035] The first winding mechanism 63, the second winding mechanism 64, the third winding mechanism 73, and the fourth winding mechanism 74 have the same structure. The structure of the first winding mechanism 63 will be described in detail below, while the descriptions of the second winding mechanism 64, the third winding mechanism 73, and the fourth winding mechanism 74 will be omitted. The first winding mechanism 63 includes a winding roller 631, a tracking roller assembly 632, and multiple pressure roller assemblies 638; the tracking roller assembly 632 and the pressure roller assemblies 638 are located on the side of the winding roller 631; the tracking roller assembly 632 includes a linear module 633, a movable plate 634 connected to the linear module 633, and a tracking roller 635 fixed on the movable plate 634; a connecting rod 636 is also fixed on the movable plate 634, and the connecting rod 636 is used for assembling and connecting multiple pressure roller assemblies 638. The pressure roller assembly 638 includes a cylinder base 6381, an adjusting cylinder 6382, a rotating shaft 6383, a swing arm 6384, and a pressure roller 6385. The cylinder base 6381 includes a first connecting hole and a second connecting hole. A connecting rod 636 is connected to the first connecting hole, and the rotating shaft 6383 is connected to the second connecting hole. One end of the swing arm 6384 is rotatably connected to the rotating shaft 6383, and the pressure roller 6385 is rotatably connected to the other end of the swing arm 6384. The adjusting cylinder 6382 is fixed to the upper end of the cylinder base 6381, and the telescopic end of the adjusting cylinder 6382 is connected to the swing arm 6384. Meanwhile, a through-beam sensor 637 is fixedly installed on the movable plate 634, and the through-beam sensor 637 is used to sense the position of the tracking roller 635.

[0036] In this system, the linear module 633 drives the tracking roller 635 to move linearly, while the high-precision through-beam sensor 637 monitors changes in roll diameter in real time. When the roll diameter of the material on the take-up roller 631 increases, the system automatically controls the linear module 633 to drive the tracking roller 635 and the pressure roller assembly 638 to retreat synchronously, maintaining the optimal contact distance with the material winding surface. This dynamic tracking mechanism ensures that ultra-narrow-width materials maintain constant contact pressure during the winding process, effectively avoiding problems such as uneven winding and roll collapse. Simultaneously, both the tracking roller 635 and the pressure roller assembly 638 are connected to the movable plate 634. The integrated design of the tracking roller 635 and the pressure roller assembly 638 reduces the space required, adapts to the slitting of ultra-narrow-width materials, and ensures complete synchronization of their movements, eliminating the response delay problems that may occur with traditional independent drives. In addition, a miniature bearing is used between the swing arm 6384 and the rotating shaft 6383, and a thrust needle roller bearing is fitted inside the second connecting hole of the cylinder seat 6381. This design significantly reduces the axial installation size of the mechanism while ensuring load-bearing capacity, making the overall structure of the pressure roller assembly 638 more compact and adapting to the stringent space utilization requirements of ultra-narrow width slitting equipment. Multiple pressure roller assemblies 638 are driven by independently adjustable cylinders 6382, specifically by proportional valves controlling the pressure. Through intelligent algorithms, the pressure of the pressure rollers 6385 can be adjusted in real time according to parameters such as material characteristics and winding speed, achieving precise fine-tuning of pressure during ultra-narrow width material winding, avoiding excessive pressure leading to material deformation or insufficient pressure causing winding slack.

[0037] The working principle of the ultra-narrow width snap-on slitting machine involved in this invention is as follows: The wide-width material is first smoothly released by the unwinding mechanism 10. After the splicing mechanism 20 completes the seamless connection between the old and new rolls, it enters the traveling and correcting mechanism 30 to precisely correct its lateral position. The traction mechanism 40 provides stable conveying power and ensures constant tension by increasing the material wrap angle. The wide-width material then enters the slitting mechanism 50, where it is precisely slit into multiple narrow-width strips by the upper and lower slitting blade groups 523. Simultaneously, the generated edge material is absorbed and removed in real time by the recycling system. The slit narrow-width strips then enter two symmetrically arranged winding units, where they pass through a brush dust removal mechanism to remove surface particles and a magnetic adsorption mechanism to suppress material drift. Finally, the four winding mechanisms achieve synchronous and precise winding, forming a neat and dense finished roll.

[0038] Compared to existing technologies, the ultra-narrow width snap-on slitting machine involved in this invention effectively solves industry problems such as uneven winding, tension fluctuation, and material drift during the slitting process of ultra-narrow width electrode materials through a symmetrically arranged double winding unit structure, combined with a unique brush dust removal mechanism and magnetic adsorption mechanism. The slitting mechanism 50 adopts a symmetrically arranged slitting blade group design, combined with a precisely adjustable edge material recycling guide module 55, ensuring the flatness and dimensional accuracy of the slitting edges of ultra-narrow electrode sheets. The four-channel independent winding system achieves dynamic balance control of tension during the winding process through the linkage mechanism of the tracking roller assembly 632 driven by the linear module 633 and the multi-pressure roller 6385, which is particularly suitable for the slitting process of ultra-narrow sub-electrode sheets. The combination of the dust removal unit with the dust cover splicing design and the front and back magnetic adsorption devices can maintain stable dust removal and positioning effects even when the material is traveling at high speed, avoiding the material displacement problems caused by debris accumulation and electrostatic adsorption in traditional equipment. The whole machine significantly improves the production quality and efficiency of new energy battery electrode sheets through modular layout and closed-loop control system.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
