[0001] The utility model belongs to the technical field of electrode foil production, and in particular relates to a multifunctional device for rolling and trimming composite winding foil materials. Background Art

[0002] Foil often has uneven edges after production and processing. In order to improve the quality of the same specifications, it is often necessary to trim the foil and remove the edge waste to ensure that the width of the finished foil meets the expected requirements.

[0003] However, the trimming devices currently available on the market often only have the trimming function of a single type of foil. When processing two composite wrapped foils, the two foils need to be rolled up first and then trimmed. This not only results in high equipment costs, but also low production efficiency and large product losses. Utility Model Content

[0009] The trimming mechanism specifically cuts off the edge waste through the cutter assemblies located on both width sides of the foil strip. The cutter assemblies are set on the knife shaft rod and can slide closer or farther away from each other under the toggle of the cutter lever to match the corresponding trimming width. The sliding drive assembly is used to provide the driving force for the sliding of the cutter lever.

The radial movement drive assembly is used to drive the translational movement of the optical shaft, so that the cutting surface and the outer peripheral wall of the optical shaft are in close contact to trim or separate to facilitate the threading of the strip or the adjustment of the spacing between the annular blade bodies. Of course, it is better to set the blade shaft to have better mobility. After the blade shaft moves, its annular blade body also releases contact with the cut strip, avoiding obstruction or scratching of the strip during axial movement of the annular blade body. The radial movement drive assembly includes a second linear drive whose cylinder is fixed to the side of the frame, and the output end of the second linear drive is connected to the shaft mounting seat.

[0025] The web-correction sensor assembly detects if the strip deviates from its center position. The roller mount, driven by a sliding drive assembly, moves horizontally, causing the take-up reel or belt-passing drive roller to adjust accordingly when the strip deviates, thereby correcting the web's deviation. The roller mount has a certain rotation range to accommodate the angle created by the height difference between the two ends of the web. The web-correction sensor assembly and its principles are common knowledge and will not be elaborated on in detail.

[0026] As a specific optimization, the sliding drive assembly includes a first linear drive with a cylinder fixed on the frame, the output end of the first linear drive is connected to the roller mounting seat, and a strip-shaped roller slide is provided on the frame.

The reeling shaft 3 is connected to the second circumferential drive and can actively rotate to pull the strips and rewind them onto the inner core.

[0045] like Figure 1-3As shown, a cutter shaft 42 and an optical shaft 43 are rotatably connected to the frame 1. The trimming mechanism 4 includes two sets of cutter assemblies 41, located on either side of the foil strip and slidably connected to the cutter shaft 42.

The drive screw 46 is transmission-connected to the first rotary driver and includes a positive thread and a reverse thread at each end. The cutter lever 45 is fixed to a drive nut 47, and the two drive nuts 47 are respectively engaged with the positive thread and the reverse thread. The cutter assembly 41 includes an annular cutter body 48, which can be axially slidably sleeved on the cutter shaft 42 through a connecting hole, and the cutting surface of its outer periphery is in close contact with the circumferential surface of the optical shaft 43; the two ends of the cutter shaft 42 are rotatably connected to the frame 1 through a shaft mounting seat 49, and the shaft mounting seat 49 is slidably connected to the cutting groove 50 on the side of the frame 1. The shaft mounting seat 49 is connected to the radial movement drive assembly to enable the optical shaft 43 to move closer to or away from the cutter shaft 42.

[0046] Specifically, the trimming mechanism 4 removes waste material from the edges via cutter assemblies 41 located on both width sides of the foil strip. The cutter assemblies 41 are mounted on a cutter shaft 42 and can slide toward or away from each other to match the corresponding trimming width when driven by a cutter lever 45. A sliding drive assembly provides the driving force for the sliding of the cutter lever 45. The cutting surface of the cutter assembly 41 abuts against the sidewall of the optical shaft 43, effectively cutting the passing strip. The sliding drive assembly is controlled by a drive screw 46, a drive nut 47, and a first rotary actuator. The upper and lower sections of the drive screw 46 have opposite thread directions, ensuring that the rotation direction of the drive screw 46 corresponds to the different axial movement directions of the two drive nuts 47, achieving synchronous control of the movement of the cutter levers 45 toward or away from each other. A connecting hole is provided in the center of the annular blade body 48, and a cutting surface is formed on the outer periphery. The cutting surface is in close contact with the outer peripheral wall of the optical shaft rod 43 and rotates synchronously to achieve the effect of cutting the passing strip.

The radial movement drive assembly specifically includes a second linear drive whose cylinder body is fixed to the side of the frame 1, and the output end of the drive is connected to the shaft rod mounting seat 49.

[0047] like Figure 1 、 4As shown, the scrap recovery mechanism 6 includes a scrap collection box 61 disposed below the trimming mechanism 4. A recovery and pulling structure 62 is provided between the scrap collection box 61 and the trimming mechanism 4. The recovery and pulling structure 62 includes a fixed roller 63 and a free roller 64 rotatably connected to the frame 1. An elastic closing assembly 65 is provided between the free roller 64 and the frame 1. The fixed roller 63 is connected to the scrap pulling drive assembly. The free roller 64 is rotatably connected to a connecting seat 66, which is slidably connected to a roller chute 67 on the side of the frame 1. The elastic closing assembly includes a transmission spring with its ends connected to the connecting seat 66 and the frame 1 respectively.

The scrap pulling drive assembly includes a second rotary drive (not specifically shown in the figure) that is transmission-connected to the fixed roller 63.

[0048] Specifically, the scrap recovery mechanism 6 receives the cut scraps through a scrap collection box 61. This box has an open top and is placed directly below the trimming mechanism 4 or simply restrained by a limit slot, making it flexible and removable. A recovery and pulling mechanism 62 is used to pull the scraps after they are cut, ensuring their separation from the strip. The scraps pass between a fixed roller 63 and a free roller 64, which close together to clamp the scraps. A scrap pulling drive assembly drives the rollers at a speed that matches the winding speed, ensuring smooth scrap recovery.

The transmission spring applies an elastic force to the connecting seat 66 pointing to the other fixed roller 63, which makes it convenient for the operator to separate the two rollers to pass the edge waste, and the two rollers have a tendency to move closer to each other to ensure the clamping transmission of the edge waste.

[0049] like Figure 1 As shown, a deviation correction sensor assembly 7 is provided between the reel 3 and the unreel 2, and the deviation correction sensor assembly 7 is fixed to the frame 1; at least one belt-passing drive roller 11 is provided between the reel 3 and the unreel 2, and the ends of the reel 3 and the belt-passing drive roller 11 are respectively rotatably connected to the frame 1 through roller mounting seats, wherein the roller mounting seat at one end of the belt-passing drive roller 11 is slidably connected to the frame 1, and the roller mounting seat is connected to the sliding drive assembly, which can drive the belt-passing drive roller 11 to tilt and rotate. The sliding drive assembly includes a first linear actuator (not specifically shown in the figure) whose cylinder body is fixed to the frame 1, and the output end of the first linear actuator is connected to the roller mounting seat. A strip-shaped roller slide is provided on the frame 1. Furthermore, the roller slide can also have an arc shape with the other end of the reel 3 as the center of the circle to adapt to the angle of the belt-passing drive roller 11 with the horizontal plane when it is tilted. The roller mounting seat is slidably connected in the roller slide.

[0050] Specifically, the deviation correction sensor assembly 7 is used to detect whether the strip deviates from the center position. A roller mounting seat of the belt-passing drive roller 11 is driven by the sliding drive assembly to move horizontally, and is used to make corresponding tilt adjustments to the belt-passing drive roller 11 when the strip deviates to achieve the deviation correction effect. Of course, the roller mounting seat has a certain rotation range to adapt to the angles caused by the different heights at both ends.

[0051] As a further optimization, both ends of the unwinding shaft 2 are rotatably connected to the frame 1. A third circumferential drive (not shown) is also provided on the frame 1, the output shaft of which is drivingly connected to the unwinding shaft 2. The unwinding shaft 2 can actively rotate to rewind the strip from the rewinding shaft 3 back onto the unwinding shaft 2, thus performing a foil rewinding function.

[0053] Specifically, the strip is wound around two trimming drive rollers 51, with the trimming assembly located between them. The height of the tangentially contacting cutting surface matches the height of the strip being driven, ensuring smooth trimming. Furthermore, the tape-passing drive roller 11 between the reel 3 and unreel 2 is used to reduce the interference caused by changes in the outer diameter of the coil during unwinding or rewinding, ensuring smooth rewinding and unwinding.

[0054] The specific working principle is as follows: A composite wrap foil roll is fixed to the unwinding shaft 2. The composite wrap foil roll is wound with a superimposed strip of foil and base tape. During the roll separation and trimming process, the foil and base tape are pulled out and separated. The foil passes through a trimming drive roller 51 and then passes through the trimming mechanism 4. The trimming mechanism 4 cuts off the edge waste. The finished product passes through another trimming drive roller 51 and a belt-passing drive roller 11, and is wound around the receiving roll on the reel 3. The edge waste passes between the fixed roller 63 and the free roller 64, is pulled and driven, and is collected in the waste collection box 61 below. The base tape passes through the belt-passing drive roller 11 and is reeled onto another reel 3. When the foil needs to be unwound, the second rotary drive stops and the third rotary drive rotates in the opposite direction, rewinding the strip on the reel 3 back to the unwinding shaft 2. When the cutting width needs to be adjusted, the second linear drive is actuated to release the optical axis rod 43 from contact with the annular blade body 48, and then the first rotary drive is actuated, and the cutter lever 45 moves to move the annular blade body 48 to the appropriate position. After adjustment, the second linear drive can be reversed.
