Description

Technical Field

[0002] Some existing lithium battery manufacturing plants face a challenge in the slitting process when performing double-width production: some existing winding devices adopt a "one-in-use and one-in-standby" turret design, that is, two winding reels are configured in a limited working space. This design limits the size of the winding reel diameter, and thus the maximum length of a single winding. Due to this limitation, the production process has to frequently change reels, which not only increases labor costs and operational complexity, but also reduces the overall capacity and efficiency of the slitting machine.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Reference below Figure 1 - Figure 6 The winding device 3 according to the embodiment of the present invention is described.

[0046] The application scenario of the winding device 3 according to the embodiment of the present invention is not limited. For example, the winding device 3 can be applied to papermaking machinery, wire and cable cloud and mother tape production, printing and packaging machinery, and lithium battery manufacturing machinery, etc.

[0047] To simplify the description, the structure of the winding device 3 is described below by taking the winding device 3 applied to a lithium battery manufacturing machine as an example, and the application of the winding device 3 in other scenarios will not be described in detail.

[0048] like Figure 1 As shown, the winding device 3 according to the first embodiment of the present invention comprises: two movable clamping head mechanisms 31 arranged at intervals along a first direction. Here, the first direction is the axial direction of the reel of the winding device 3.

[0049] like Figure 2 As shown, each movable chuck mechanism 31 comprises: a base 311, a movable seat 312, a first driving assembly 313 and a chuck 314. The movable seat 312 is arranged on the base 311. The first driving assembly 313 is connected between the base 311 and the movable seat 312 to drive the movable seat 312 to move along a first direction. The chuck 314 is rotatably arranged on the movable seat 312.

[0050] The base 311 is the basic supporting part of the movable clamping head mechanism 31 . The base 311 is stably mounted on the winding device 3 to ensure that the movable clamping head mechanism 31 remains stable during operation.

[0051] The movable seat 312 is arranged on the base 311 and can move relative to the base 311 along the first direction (i.e., the axial direction of the reel in the winding device 3). This design enables the movable seat 312 to adjust its position according to the winding requirements to adapt to material sheets of different sizes. Whether it is processing large or small-sized material sheets, the movable seat 312 can adapt, thereby ensuring the smooth progress of the winding process and improving the adaptability of the winding device 3. At the same time, at the beginning and completion stages of the winding operation, the release and positioning of the reel can be achieved by controlling the movement of the movable seat 312. For example: before the winding begins, the movable seat 312 can be pre-adjusted to an appropriate position to facilitate the smooth installation of the reel and the initial winding of the material sheet. When the winding operation is nearing its end, the movable seat 312 can move in the opposite direction, so that the reel can be released smoothly, which is convenient for the subsequent processing or transportation of the material roll.

[0052] The first driving assembly 313 is connected between the base 311 and the moving base 312. The first driving assembly 313 is used to drive the moving base 312 to move along a first direction relative to the base 311. By controlling the first driving assembly 313, the positioning of the moving base 312 on the base 311 can be achieved, thereby ensuring that the clamping head 314 can accurately approach or leave the reel.

[0053] The clamp 314 is rotatably disposed on the movable seat 312. The clamp 314 is a component that actually performs the action of clamping and releasing the material sheet. Optionally, the shape and size of the clamp 314 are suitable for installing the reel to ensure that the clamp 314 can stably install the reel for winding. Specifically, the clamp 314 adopts a nested structure, that is, the inside of the clamp 314 has a groove or hole that matches the outer diameter of the reel, so that the reel can be tightly embedded therein. When the clamp 314 starts to rotate, the reel connected thereto can rotate synchronously to ensure that the material sheet can be stably wound around the axis of the reel.

[0054] Among them, combined Figure 1 The clamps 314 of the two movable clamp mechanisms 31 are located on the sides of the two movable seats 312 facing each other, and the two clamps 314 are used to cooperate with the winding material sheets to form a material roll.

[0055] Specifically, the two clamps 314 are respectively mounted on the two movable seats 312, and their directions are opposite to each other. This layout ensures that the two clamps 314 can form relatively stable clamping points on both sides of the material sheet when clamping the material sheet, so that the two ends of the material sheet can be firmly clamped between the two clamps 314.

[0056] Optionally, the chuck 314 may be an air expansion chuck 314 or a differential shaft.

[0057] At least one movable clamping head mechanism 31 in the winding device 3 further includes: a magnetic powder clutch 316 and a second driving component 317 .

[0058] It is worth noting that the magnetic powder clutch 316 is a device that uses a magnetic field to transmit torque. The magnetic powder clutch 316 adjusts the magnetic field strength generated by electromagnetic induction by controlling the input voltage. The change in the magnetic field strength directly affects the friction between the magnetic powder particles, thereby achieving precise control of the torque of the clutch output shaft 3162. When the magnetic powder clutch 316 is applied to the winding device 3 of the present invention, the torque transmitted to the chuck 314 by the output shaft 3162 is finely adjusted by adjusting its input voltage. This torque adjustment can determine the tension to which the material sheet is subjected during winding, thereby ensuring the stability and consistency of the winding tension. And a stable winding tension can ensure the flatness and tightness of the material roll. Therefore, through the precise control of the magnetic powder clutch 316, problems such as deformation, looseness or breakage of the material roll caused by uneven tension can be avoided, significantly improving product quality.

[0059] The magnetic powder clutch 316 has an input shaft 3161 and an output shaft 3162. The output shaft 3162 is connected to the clamp 314 to control the winding tension. The second driving component 317 is connected to the input shaft 3161 to drive the input shaft 3161 to rotate.

[0060] When the second driving assembly 317 is started, it drives the input shaft 3161 of the magnetic powder clutch 316 to rotate. The rotational power of the input shaft 3161 is transmitted to the output shaft 3162 through the magnetic powder working chamber inside the magnetic powder clutch 316. In this process, the magnetic powder clutch 316 adjusts the intensity of the electromagnetic induction magnetic field according to the magnitude of the input voltage, thereby controlling the friction between the magnetic powder particles, and realizing precise adjustment of the torque of the output shaft 3162.

[0061] Since the output shaft 3162 is connected to the chuck 314, the change in the torque of the output shaft 3162 will directly affect the tension applied by the chuck 314 to the material sheet. Specifically, when the winding tension needs to be increased, the input voltage of the magnetic powder clutch 316 can be increased to enhance the electromagnetic induction magnetic field, increase the friction between the magnetic powder particles, and thus increase the torque of the output shaft 3162 and the tension of the chuck 314 on the material sheet. Conversely, when the winding tension needs to be reduced, the input voltage can be reduced to weaken the electromagnetic induction magnetic field and reduce the friction between the magnetic powder particles, thereby reducing the torque of the output shaft 3162 and the tension of the chuck 314 on the material sheet.

[0062] The magnetic powder clutch 316 ensures that the output shaft 3162 maintains a stable speed and torque output during rotation, avoiding the problem of uneven winding tension caused by torque fluctuation. At the same time, by controlling the magnitude and direction of the input voltage, the magnetic powder clutch 316 can achieve fine adjustment of the winding tension to meet the tension control requirements under different materials and winding requirements.

[0063] As the material sheets on the reel gradually accumulate and the reel diameter gradually increases, the torque and load borne by the reeling device 3 will also increase accordingly. This is because the magnetic powder clutch 316 can change the strength of the electromagnetic induction magnetic field by controlling the current in the coil. This magnetic field will act on the magnetic powder particles inside the clutch, causing them to form a chain or columnar structure, thereby transmitting torque. As the reel diameter increases, the torque required by the reeling device 3 will also increase, and the magnetic powder clutch 316 will correspondingly increase the current in the coil, enhance the magnetic field strength, and allow more magnetic powder particles to participate in torque transmission to maintain the stability of the output torque.

[0064] It should be noted that the structure of the magnetic powder clutch 316 itself is not the technical improvement innovation of the present application scheme, and the internal structure of the magnetic powder clutch 316 is already a prior art and is well known to conventional technicians in this field. Therefore, the internal structure of the magnetic powder clutch 316 is not described in detail here. The focus is on how to combine the magnetic powder clutch 316 with the winding device 3 to achieve constant tension winding.

[0065] In some embodiments, one of the movable chuck mechanisms 31 in the winding device 3 includes: a magnetic powder clutch 316 and a second driving member; and the chuck 314 in the other movable chuck mechanism 31 is a driven chuck 314. In this configuration, the driven chuck 314 does not need to be equipped with an independent driving source and control system. The driven chuck 314 is connected to the active chuck 314 through a material sheet to achieve synchronous rotation. This configuration can simplify the structure, reduce the number of parts and the complexity of installation, thereby reducing the manufacturing cost and maintenance cost of the winding device 3.

[0066] In order to improve the precise control of the material roll, in some optional embodiments, the two movable clamping head mechanisms 31 of the winding device 3 both include a magnetic powder clutch 316 and a second driving member.

[0067] Specifically, during the winding process, the second driving members of the two mobile clamping head mechanisms 31 respectively drive the input shafts 3161 of their respective magnetic powder clutches 316 to rotate. The magnetic powder clutches 316 adjust the strength of the electromagnetic induction magnetic field according to the instructions of the control system, thereby changing the friction between the magnetic powder particles and realizing precise control of the torque of the output shaft 3162. The two clamping heads 314 clamp and drive the material sheet to be wound through the torque adjusted by their respective magnetic powder clutches 316, while maintaining a stable winding tension.

[0068] This dual-drive design allows each clamp 314 to be independently and accurately controlled, reducing load fluctuations and balancing the power output of the entire winding device 3, thereby improving the smoothness of operation and improving the stability and accuracy of the material roll winding process.

[0069] According to the winding device 3 of the embodiment of the present invention, the position of the clamping head 314 is controlled by providing a movable seat 312 to achieve installation and unloading of the material roll.

[0070] By installing the magnetic powder clutch 316, the control accuracy and stability of the winding tension of the winding device 3 are improved. As the coil diameter gradually increases, the magnetic powder clutch 316 can adjust the output torque to ensure that the coil always maintains appropriate tension during the winding process, thereby effectively preventing the coil from wrinkling, loosening, and other problems caused by uneven tension, and also ensuring the flatness and tightness of the coil under large coil diameter conditions, thereby improving the quality of the wound product.

[0071] In addition, by abandoning the traditional spare turret design, the winding device 3 of the embodiment of the present invention is simplified in structure to a certain extent, further increasing the working space, thus significantly increasing the single winding length, reducing the frequency of the roll changing operation, and further improving the production efficiency and capacity.

[0072] According to some embodiments of the winding device 3 of the present invention, at least one of the input shaft 3161 and the output shaft 3162 is a hollow tube and is sleeved on the other.

[0073] Since one of the shafts is a hollow tube, the hollow tube can provide a passage for the other shaft inside without increasing the extra volume. In this way, the input shaft 3161 and the output shaft 3162 of the magnetic powder clutch 316 are located on the same axis, making the overall structure of the magnetic powder clutch 316 more compact, which is conducive to saving the space occupied by the magnetic powder clutch 316 in the winding device 3, thereby releasing more working space for the winding process of the feed roll, thereby providing conditions for increasing the winding length.

[0074] In addition, such a configuration can also enable the input shaft 3161 and the output shaft 3162 to maintain relatively independent spatial positions during operation, thereby avoiding physical interference between the two.

[0075] In some Figure 3 In the illustrated embodiment, the input shaft 3161 is a hollow tube, and the input shaft 3161 is sleeved on the outside of the output shaft 3162. Optionally, a bearing box 318 is provided between the output shaft 3162 and the moving seat 312.

[0076] According to some embodiments of the present invention, the winding device 3, such as Figure 2 - Figure 4 As shown, the second driving assembly 317 includes: a winding driving motor 3171, a synchronous wheel 3172 and a synchronous belt 3173. The winding driving motor 3171 is installed on the moving seat 312. The synchronous wheel 3172 is connected to the winding driving motor 3171. The synchronous belt 3173 is matched with the synchronous wheel 3172 and the input shaft 3161 to achieve synchronous rotation.

[0077] The winding drive motor 3171 is used as the power source of the second drive assembly 317 and is responsible for generating rotational power. The winding drive motor 3171 is installed on the moving base 312 so that it can move with the movement of the moving base 312.

[0078] The synchronous wheel 3172 is connected to the winding drive motor 3171. Specifically, the synchronous wheel 3172 is closely connected to the output end of the winding drive motor 3171 to ensure that the winding The power of the motor is accurately transmitted to the synchronous wheel 3172. Optionally, the synchronous wheel 3172 can be directly connected to the winding drive motor 3171 and fixed by a fastening device such as a bolt, a pin or a keyway; or, the synchronous wheel 3172 and the winding drive motor 3171 are indirectly connected through a coupling. The connection structure between the synchronous wheel 3172 and the winding drive motor 3171 in the present application can adopt a known solution in the prior art. The connection structure itself is not the core point of the present application solution, so it will not be repeated here.

[0079] In some optional embodiments, such as Figure 3 As shown, the magnetic powder clutch 316 and the chuck 314 are coaxially arranged and located above the winding drive motor 3171.

[0080] Firstly, the coaxial arrangement of the magnetic powder clutch 316 and the chuck 314 means that their rotation axes coincide with each other. This arrangement can reduce space occupation and make the structure of the entire winding device 3 more compact, thereby releasing more space for winding the material roll.

[0081] Secondly, after the magnetic powder clutch 316 and the chuck 314 are coaxial, the transmission path between them is shorter and more direct, which helps to reduce energy loss during the transmission process and improve the transmission efficiency of the magnetic powder clutch 316. At the same time, it also helps to reduce the vibration and noise caused by the different axes, and further improves the stability and reliability of the winding device 3.

[0082] When the magnetic powder clutch 316 and the chuck 314 are coaxially arranged and located above the winding drive motor 3171, the space below is released to ensure that the roll can fully expand its radius during the winding process, reducing the interference or restriction of the components in the winding device 3 on the roll, thereby achieving a larger winding radius. As the roll diameter increases, the amount of material that can be processed in a single winding operation also increases, thereby improving the winding efficiency. This not only reduces the number of frequent changes of rolls, but also reduces labor costs and time costs.

[0083] Moreover, placing the winding drive motor 3171 at the bottom also moves the center of gravity of the entire winding device 3 downward. As the diameter of the material roll increases, its moment of inertia will increase accordingly, which is easy to cause shaking. However, since the winding drive motor 3171 is arranged at the bottom, the stable support of the moving seat 312 can be increased, so that the large-diameter material roll can remain relatively stable during the winding process, reducing shaking and ensuring a stable winding environment. This helps to maintain the stability and fit of the material roll, thereby improving the winding quality.

[0084] According to some embodiments of the winding device 3 of the present invention, the first driving component 313 includes: a moving cylinder, a piston rod of which is connected to the moving seat 312; or, the first driving component 313 includes: a moving motor 3131, and the moving motor 3131 is connected to the moving seat 312 via a screw nut assembly 3132.

[0085] In some embodiments, the first driving assembly 313 includes a moving cylinder, the piston rod of which is connected to the moving seat 312 .

[0086] It is known that a mobile cylinder is a device that converts air pressure into mechanical energy, and contains a piston and a cylinder body. When compressed air is filled into the cylinder, the air pressure acts on the piston, pushing the piston to move linearly in the cylinder. The piston rod, as an extension of the piston, is connected to the outside of the cylinder, thereby transmitting the linear motion inside the cylinder to the external load.

[0087] When the first driving assembly 313 includes a moving cylinder, the piston rod of the moving cylinder is connected to the moving seat 312. This allows the linear motion of the moving cylinder to be directly and effectively converted into the movement of the moving seat 312 on the base 311. Optionally, the piston rod and the moving seat 312 are connected by a connecting piece to ensure the stability and reliability of the connection. The connecting piece includes but is not limited to bolts, pins, etc.

[0088] Optionally, the moving cylinder can control the telescopic length of the piston cylinder. Specifically, by controlling the air intake and exhaust volume of the moving cylinder, the telescopic length of the piston rod can be effectively controlled, thereby driving the moving seat 312 to move along the first direction on the base 311. When the moving seat 312 moves along the first direction on the base 311, it can achieve flexible placement and stable clamping of reels of different sizes by driving the linkage of the clamp 314, and also simplify the installation and removal process of the reel, bringing convenience to the winding operation.

[0089] Or, in some Figure 2 In the illustrated embodiment, the first driving assembly 313 includes a moving motor 3131 . The moving motor 3131 is connected to the moving base 312 via a lead screw nut assembly 3132 .

[0090] As a power source, the mobile motor 3131 is responsible for providing the necessary torque and speed to drive the lead screw to rotate. The mobile motor 3131 usually has high control accuracy and response speed, and can adjust output parameters according to the control signal, thereby achieving accurate control of the position of the mobile seat 312.

[0091] Optionally, the mobile motor 3131 is connected to the lead screw through a transmission device (such as a coupling, a reducer, etc.) to ensure that the torque and speed output by the motor can be efficiently transmitted to the lead screw. At the same time, the nut in the lead screw nut assembly 3132 is fixedly connected to the mobile seat 312 through a connecting member (such as a bolt, a pin, etc.). In this way, when the nut moves on the lead screw, it can drive the mobile seat 312 to move linearly together.

[0092] According to some embodiments of the present invention, the winding device 3, such as Figure 2 As shown, the movable clamp mechanism 31 further includes: a translation guide rail 315. The translation guide rail 315 is installed on the base 311 along the first direction, and the movable seat 312 is matched on the translation guide rail 315 through a translation slider.

[0093] The translation guide rail 315 serves as a guide device for the movement of the moving base 312, and its function is to ensure that the moving base 312 can perform accurate and stable linear motion along a preset first direction.

[0094] When the moving seat 312 needs to move, the translation slider slides along the slide groove of the guide rail, thereby driving the moving seat 312 to move along the first direction. This matching mode of the slider and the guide rail reduces the friction and wear between the moving seat 312 and the guide rail, and improves the flexibility and smoothness of the movement of the moving seat 312.

[0095] The precise movement of the movable seat 312 is conducive to the precise control of the position of the clamping head 314. In this way, it can be ensured that the clamping head 314 can accurately align with the edge of the roll when clamping the roll, thereby reducing the winding error caused by position deviation.

[0096] In addition, during the continuous winding process, precise control of the position of the clamp 314 helps to maintain the consistency of the winding tension and prevent winding quality problems caused by tension fluctuations.

[0097] Moreover, the fast and accurate positioning of the clamping head 314 can shorten the adjustment time of the winding device 3 and improve the efficiency of roll changing and winding.

[0098] like Figure 2 , Figure 4 , Figure 5 As shown, the winding device 3 according to some embodiments of the present invention further includes: a material roll supporting mechanism 32, which is located between the moving seats 312 of the two moving clamping head mechanisms 31 to support the material roll unloaded from the two clamping heads 314.

[0099] The material roll support mechanism 32 is located between the moving seats 312 of the two moving clamping head mechanisms 31, and its main function is to provide temporary support for the material roll to facilitate subsequent operations such as material roll transfer, storage or further processing.

[0100] Optionally, there are two roll support mechanisms 32, which are respectively located at the two ends of the roll. When the roll is unloaded from the mobile clamping head mechanisms 31 on both sides, the two ends of the roll can be smoothly transferred to the two roll support mechanisms 32 to prevent the roll from falling or being damaged.

[0101] In some optional embodiments, such as Figure 5 As shown, the material roll support mechanism 32 includes: a support block 321 and a lifting member 322. The top surface of the support block 321 is a support surface 3211 for placing the material roll; the lifting member 322 has a height-adjustable lifting head, which is connected to the support block 321.

[0102] In this way, when the clamp 314 releases the reel, the reel can be temporarily supported by the support surface 3211. Optionally, a limiting component is provided on the support surface 3211. The limiting component can be: a limiting column, a limiting block, etc.

[0103] For example, when the roll is placed on the support surface 3211, the limit posts, limit blocks, etc. are located on both sides of the roll in the radial direction, and prevent the roll from rolling on the support surface 3211 by physical blocking, thereby maintaining the stability and safety of the winding operation.

[0104] Optionally, an anti-skid layer is provided on the support surface 3211. The anti-skid layer can be a material layer with a high friction coefficient. For example, an anti-skid layer made of materials such as rubber, polyurethane, and PVC has good wear resistance and anti-skid properties, and can maintain a stable anti-skid effect. At the same time, their softness and elasticity can also absorb vibration and impact to a certain extent, protecting the surface of the reel from damage. At the same time, the surface of the anti-skid layer can also be specially treated. For example, processes such as frosting, grooving, and spraying anti-skid agents can be used to increase the roughness of the surface and increase the friction between the support surface 3211 and the reel. These treatment measures can further prevent the reel from sliding or rolling on the support surface 3211, ensuring its stability during the winding operation.

[0105] The lifting member 322 includes a height-adjustable lifting head, which is used to adjust the height of the support block 321. In this way, by adjusting the height of the lifting head, it is possible to ensure that the support block 321 is in a suitable position to provide stable support, thereby eliminating the reliance of the winding device 3 on a roll of a specific specification, thereby improving the versatility and flexibility of the winding device 3.

[0106] Optionally, the support surface 3211 is a V-shaped surface. The V-shaped surface can naturally form a low area that is convenient for placing the roll. When the roll is at the lowest end of the V-shaped surface, its two side edges will naturally fit on the two side walls of the V-shaped groove to form a stable support structure, limiting the horizontal movement of the roll. This natural positioning method reduces the operator's manual adjustment of the roll position and improves work efficiency. Even in the absence of additional limit components, the V-shaped surface can maintain the stability of the roll during the winding operation.

[0107] The groove of the V-shaped surface has a certain width range, which can adapt to rolls of different diameters. When the diameter of the roll changes, it is only necessary to adjust the height position of the lifting head in the lifting member 322 so that the roll is as close to the appropriate position of the V-shaped surface as possible to achieve stable support. This design improves the compatibility and adaptability of the winding device 3 to rolls of different diameters.

[0108] Alternatively, if Figure 5As shown, the material roll support mechanism 32 further includes a weighing sensor 323. The weighing sensor 323 is arranged on the supporting surface 3211 to weigh the weight of the material roll.

[0109] The weighing sensor 323 is mounted on the support surface 3211 and directly bears and measures the weight of the material roll. This direct measurement method ensures the accuracy and real-time nature of the data. As the material sheet is continuously wound onto the reel, the weight of the material roll gradually increases, and the weighing sensor 323 can capture this change in real time, convert this change into a recognizable electrical signal, and transmit the electrical signal to the control system.

[0110] The operator can preset a target weight value in the control system based on the material's physical properties such as density and thickness, as well as the desired reel weight. When the roll weight reaches the preset threshold, the control system can trigger sound and light alarms, display prompts, etc., so that the operator can understand the production situation, prompting them to pay attention to the current production status or perform necessary operations.

[0111] Optionally, the support surface 3211 has a certain width. The reel can completely fall on the support surface 3211 and contact the weighing sensor 323, thereby improving the accuracy and reliability of weighing.

[0112] In some Figure 5 In the illustrated embodiment, the material roll support mechanism 32 further includes: a support seat 324 and a lifting rail 326. The lifting member 322 is mounted on the support seat 324. The lifting rail 326 is vertically mounted on the support seat 324, and the support block 321 is matched on the lifting rail 326 through a lifting slider 325.

[0113] The support base 324 is the base of the coil support mechanism 32, and it provides a stable support platform to ensure the stability of the coil support mechanism 32 during operation. Optionally, the support base 324 is a metal material. For example, the support base 324 is a steel or aluminum alloy part to withstand the weight of the coil and the force generated by the lifting movement.

[0114] The lifting guide rail 326 is vertically installed on the support seat 324 to provide precise guidance for the lifting movement of the support block 321, enhance the stable supporting effect of the support block 321, ensure the stability of the material roll during the winding process, and improve the winding flatness.

[0115] The lifting slider 325 is mounted on the support block 321 and cooperates with the lifting guide rail 326. Optionally, a rolling body (such as a ball, roller, etc.) is provided between the lifting slider 325 and the lifting guide rail 326 to reduce friction and wear between the guide rail and the lifting slider 325. When the lifting member 322 is working, it pushes the lifting slider 325 to move up and down along the guide rail, thereby driving the support block 321 to achieve lifting motion.

[0116] In some optional embodiments, such as Figure 1 As shown, there are two material roll supporting mechanisms 32 , which are respectively mounted on the bases 311 of the two movable clamping head mechanisms 31 and are located below the clamping heads 314 .

[0117] The material roll support mechanism 32 can support the material roll from both sides, thereby improving the stability of the support and reducing the tilting or shaking caused by imbalance.

[0118] In some optional embodiments, the two roll supporting mechanisms 32 can be raised or lowered simultaneously so as to accurately position the roll at a designated position required for production.

[0119] Alternatively, the two roll support mechanisms 32 can be controlled to rise and fall separately, so that the lifting height of each support mechanism can be precisely adjusted, which helps to ensure that the heights of the two ends of the roll are completely consistent, thereby avoiding tilting or twisting caused by height differences.

[0120] In order to take into account the convenience and flexibility of the use of the material roll support mechanism 32. In some embodiments, the two material roll support mechanisms 32 can be raised and lowered at the same time, or can be raised and lowered separately.

[0121] like Figure 7 As shown, the slitting machine 1000 according to the second embodiment of the present invention comprises at least one winding device 3 according to the first embodiment of the present invention. The slitting machine 1000 according to the embodiment of the present invention, by providing the winding device 3, increases the winding diameter, reduces the frequency of changing the roll, and improves the working efficiency of the slitting machine 1000.

[0122] According to some embodiments of the slitting machine 1000 of the present invention, the winding device 3 further includes: a transverse bottom plate 33 , and the two movable clamping head mechanisms 31 are both installed on the transverse bottom plate 33 .

[0123] The transverse bottom plate 33 is not only used to support the winding device 3, but also serves as a moving platform to drive the two moving clamping head mechanisms 31 installed thereon to perform precise transverse movement.

[0124] For example, in the operation process of the slitting machine 1000, when a roll of material is wound up, in order not to affect subsequent operations or to facilitate roll change and other processing, the roll needs to be transferred out of the main operation space in time. At this time, the transverse bottom plate 33 moves laterally and drives the two mobile chuck mechanisms 31 thereon to move synchronously. The two mobile chuck mechanisms 31 are closely connected to the transverse bottom plate 33 through a fixing device to ensure that there is no relative displacement or shaking during the movement, thereby ensuring the stability and safety of the roll during the transfer process.

[0125] The lateral movement of the lateral bottom plate 33 can fully utilize the space resources around the slitting machine 1000, so that the material roll will not collide or interfere with other equipment or components during the transfer process.

[0126] The slitting machine 1000 further includes: a main frame 4 and a third driving assembly 5, wherein a first position a is provided inside the main frame 4 and a second position b is provided outside the main frame 4. The third driving assembly 5 is connected between the main frame 4 and the transverse bottom plate 33 to drive the transverse bottom plate 33 to switch between the first position a and the second position b.

[0127] The first position a is an area designed for coiling in the slitting machine 1000, which is located in the main frame 4 and can accommodate the coiling device 3 and the coils thereon. At the first position a, the coils are gradually accumulated to form a roll of a certain diameter and length.

[0128] The second position b is located outside the main frame 4 and is an area without interference from the main frame 4. The second position b can be used to transfer the roll. When the roll is wound at the first position a, it needs to be transferred out in a timely and safe manner to make room for the next roll. At this time, the material can be transferred to the second position b for subsequent operations.

[0129] In some optional embodiments, there is enough space around the second position b, and the material roll can be transferred using equipment such as a forklift.

[0130] The third driving assembly 5 is used to drive the transverse bottom plate 33 to move on the main frame 4. Specifically, when the position of the material roll needs to be switched, the third driving assembly 5 generates a driving torque, which is converted into a lateral movement of the transverse bottom plate 33.

[0131] According to some embodiments of the present invention, the third driving assembly 5 includes a traverse rack 51, a traverse drive motor 52, and a traverse gear (not shown). The traverse rack 51 extends from the first position a to the second position b. The traverse drive motor 52 is mounted on the traverse bottom plate 33. The traverse gear is connected to the traverse drive motor 52 and meshes with the traverse rack 51.

[0132] In the above technical solution, the transverse rack 51 is extended from the first position a to the second position b. The transverse rack 51 has a series of equally spaced teeth, which mesh with the teeth of the transverse gear to transmit power and guide the moving direction of the transverse bottom plate 33.

[0133] The traverse drive motor 52 is the power source of the third drive assembly 5, and it is installed on the traverse base plate 33. Then the traverse drive motor 52 can move with the movement of the base plate, thereby realizing direct drive of the power source and reducing energy loss and error accumulation in the transmission chain. Optionally, the traverse drive motor 52 is a servo motor or a stepper motor. This ensures that the traverse drive motor 52 can output a stable driving force.

[0134] The transverse gear is used to connect the transverse drive motor 52 and the transverse rack 51. It is installed at the output end of the transverse drive motor 52. The tooth shape of the transverse gear matches the tooth shape of the transverse rack 51. When the transverse drive motor 52 is started, the transverse gear starts to rotate and meshes with the transverse rack 51, thereby converting the rotational motion of the transverse drive motor 52 into the linear motion of the transverse base plate 33.

[0135] According to some embodiments of the present invention, the slitting machine 1000, such as Figure 7 As shown, the slitting machine 1000 further includes: an external fixing seat 6, a transverse guide rail 7 and a transverse slide block 8. The external fixing seat 6 is located at the second position b. One end of the transverse guide rail 7 is connected to the external fixing seat 6, and the other end is connected to the main frame 4. The transverse slide block 8 is matched on the transverse guide rail 7, and the transverse slide block 8 is connected to the transverse bottom plate 33.

[0136] In the above technical solution, the external fixing seat 6 is fixed at the second position b. The external fixing seat 6 not only provides a stable support point for the transverse guide rail 7, but also ensures the stability and reliability of the entire transverse system.

[0137] The traverse guide rail 7 is used to connect the external fixing seat 6 and the main frame 4. One end of it is firmly connected to the external fixing seat 6, and the other end is connected to the bottom of the main frame 4, forming a straight track.

[0138] The traverse slider 8 is slidably mounted on the traverse guide rail 7, and is connected to the traverse base plate 33, and slides on the guide rail as the traverse base plate 33 moves. The structure of the traverse slider 8 is suitable for closely fitting with the traverse guide rail 7, while ensuring that the traverse slider 8 slides smoothly in the traverse guide rail 7.

[0139] Specifically, during the operation of the slitting machine 1000, when the transverse bottom plate 33 needs to be moved, the transverse drive motor 52 is started and drives the transverse gear to rotate. The transverse gear is meshed with the transverse rack 51, converting the rotational motion into linear motion, pushing the transverse bottom plate 33 to move along the transverse guide rail 7. The transverse slider 8 serves as a connecting component between the transverse bottom plate 33 and the transverse guide rail 7, ensuring the stability and accuracy of the transverse bottom plate 33 during movement. As the transverse bottom plate 33 moves, it gradually approaches the target position (such as the second position b) from the initial position (such as the first position a), and finally stops at the external fixed seat 6.

[0140] According to the present invention, some Figure 8 The slitting machine 1000 of the embodiment shown also includes: an unwinding device 1 and a slitting knife 2. The unwinding device 1 is used to unwind the material sheet. The slitting knife 2 is used to cut the material sheet into at least two divided material sheets. There are at least two winding devices 3, and the two clamps 314 of each winding device 3 wind up a single divided material sheet.

[0141] The unwinding device 1 is the starting part of the slitting machine 1000, and is responsible for smoothly unwinding the rolled material and transferring it to the subsequent processing area. Optionally, the unwinding device 1 includes: an unwinding frame, a guide roller, and an unwinding drive motor.

[0142] The slitting knife 2 is used to accurately cut the discharged material sheet into sub-sheets. Optionally, the position and / or number of the slitting knife 2 are adjustable. In this way, the width of the cut sub-sheets can be flexibly changed to meet different production requirements.

[0143] The winding device 3 serves as the terminal of the slitting machine 1000 and is responsible for winding the cut pieces into rolls.

[0144] The unwinding device 1, the slitting knife 2 and the rewinding device 3 work in coordination to realize the processing actions of the material from unwinding to cutting and then to rewinding.
