Description

Technical Field

[0001] This utility model relates to the field of slitting equipment technology, and in particular to a slitting machine unwinding device. Background Technology

[0002] Slitting machines are key downstream processing equipment in industrial production. They are mainly used to precisely slit wide or large-diameter master rolls into multiple narrow or small-diameter sub-rolls along the longitudinal direction. Their core function is to efficiently change the width or diameter of the roll to meet the needs of downstream processing or final use. This equipment is widely used in the production and processing of paper, plastic film, non-woven fabric, metal foil, textiles, and various composite materials. It is an indispensable link in modern roll processing lines, significantly improving material utilization and the efficiency of subsequent processes.

[0003] In the operation of a slitting machine, the unwinding device plays a crucial role, responsible for conveying the film wound on the roll to the subsequent slitting mechanism. However, the unwinding device has certain problems. For example, existing unwinding rollers are usually of fixed size, and the same unwinding roller can only fit one size of roll. When encountering a larger roll, the roll will wobble on the unwinding roller, affecting the stability of film conveying. For smaller rolls, they cannot fit well on the unwinding roller, which means that if a different size roll needs to be changed during production, the unwinding roller must be changed accordingly, increasing the complexity of operation, reducing production efficiency, and increasing the cost of equipment use, greatly limiting its applicability. On the other hand, in traditional slitting equipment, the unwinding roller often adopts a single-sided cantilever installation structure, and its axial free end lacks an effective radial support component, which causes wobbling during rotation, thus affecting the subsequent slitting accuracy. Therefore, we urgently need a slitting machine unwinding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the unwinding rollers in the prior art cannot be adapted to rolls of various sizes, and that the unwinding rollers in slitting equipment often adopt a single-sided cantilever installation structure, which causes swaying during rotation. Therefore, this invention proposes an unwinding device for a slitting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A slitting machine unwinding device includes a frame and a slitting section mounted on the frame for cutting. A chuck for clamping is fixedly connected to the frame via a motor. An unwinding roller for placing a roll is detachably mounted on the chuck. The device also includes: a lever rotatably connected to the frame, the lever having a stabilizing part for securing the unwinding roller; and rectangular grooves equidistantly formed on the unwinding roller in annular pattern. The inner wall of the rectangular grooves is symmetrically provided with I-shaped guide rails for guidance. A limiting part for adapting to the inner diameter of the roll is provided within the rectangular grooves.

[0006] In order to adapt to different inner diameters of the roll, preferably, the limiting part includes an adapter plate disposed in a rectangular slide groove. The adapter plate is symmetrically provided with slots that are adapted to the "I"-shaped guide rail. When the adapter plate slides in the rectangular slide groove, the "I"-shaped guide rail abuts against the inner wall of the slot to form a stable area.

[0007] To improve the stability of the drum installation, the adapter plate is further provided with a silicone plate that abuts against the inner diameter of the drum, and at least three sets of supporting springs are provided between the adapter plate and the silicone plate, with the two ends of the springs abutting against the adapter plate and the silicone plate respectively.

[0008] To improve the stability of the unwinding roll rotation, preferably, the stabilizing part includes a hydraulic cylinder fixedly installed at the end of the lever. The output end of the hydraulic cylinder is fixedly connected to a connecting plate, and a connecting rod is rotatably connected to the connecting plate through a bearing. When the hydraulic cylinder is working, the connection point of the connecting rod is inserted into the end of the unwinding roll and forms a locking zone.

[0009] To further limit the position of the adapter plate, a limiting plate is fixedly connected to the connecting rod, and a limiting rod is fixedly connected to the limiting plate at the position corresponding to the adapter plate. The adapter plate has a limiting hole that matches the limiting rod. When the connecting rod is inserted into the unwinding roller, the limiting rod is inserted into the limiting hole and forms a limiting area.

[0010] In order for the lever to swing, preferably, a drive motor is fixedly connected to the frame, and the output end of the drive motor is fixedly connected to the lever. When the drive motor is working, the lever swings along the axis of the drive motor.

[0011] Compared with the prior art, the present invention provides a slitting machine unwinding device, which has the following beneficial effects: 1. The unwinding device of this slitting machine, through the cooperation of rectangular slide groove, "I" shaped guide rail, adapter plate and card slot, allows the adapter plate to flexibly slide and adjust its position according to the inner diameter of the roll. Combined with the elastic support of silicone plate and spring, it can closely fit the inner wall of rolls with different inner diameters. It can adapt to rolls of various sizes without changing the unwinding roller, reducing the complexity of operation, lowering the cost of equipment use, effectively expanding the applicability of the device and improving production efficiency.

[0012] 2. The unwinding device of this slitting machine uses a drive motor to swing a lever to a suitable position. A hydraulic cylinder pushes the connecting plate and connecting rod to move, so that the connecting rod inserts into the end of the unwinding roller to form a locking zone, effectively supporting the axial free end of the unwinding roller. At the same time, the limiting plate on the connecting rod cooperates with the limiting hole of the adapter plate to form a limiting zone, preventing the adapter plate from sliding. The bearing connection between the connecting plate and the connecting rod ensures that it does not affect the rotation of the unwinding roller. The overall structure solves the swaying problem of traditional single-sided cantilever installation and ensures the stability of slitting.

[0013] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model can adapt to the inner walls of drums with different inner diameters, and can adapt to drums of various sizes without changing the unwinding roller. This reduces the complexity of operation, lowers the cost of equipment use, effectively expands the applicability of the device, improves production efficiency, ensures the stability of the unwinding roller when it rotates, avoids shaking, and thus improves the processing accuracy.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Example: Reference Figures 1-6 A slitting machine unwinding device includes a frame 1 and a slitting section mounted on the frame 1 for cutting. Here, the slitting section includes a guide rail and a cutting section mounted on the frame 1 to drive the cutting blade. The guide rail consists of two sets of parallel linear guide rails, which are fixedly mounted inside the frame 1. A movable seat is mounted on the linear guide rail, which supports the cutting section. The linear guide rail drives the cutting section to move laterally and longitudinally, ensuring the stability of the movable seat during movement. The cutting section is mounted on the movable seat and includes a cutting blade holder, a cutting blade, and a cutting motor for driving the cutting blade to rotate. This is a conventional technical solution and will not be described in detail here.

[0019] A chuck 2 for clamping is fixedly connected to the frame 1 via a motor. An unwinding roller 3 for placing the roll is detachably installed on the chuck 2. Here, the chuck 2 is a three-jaw chuck 2, which can securely fix the end of the unwinding roller 3. The motor is used to drive the unwinding roller 3 to rotate, and together with the linear guide rail and the cutting part, the roll is cut.

[0020] A rectangular groove 5 is equidistantly arranged on the unwinding roller 3. The inner wall of the rectangular groove 5 is symmetrically provided with "I"-shaped guide rails 6 for guidance. The rectangular groove 5 is provided with a limiting part for adapting to the inner diameter of the drum. The limiting part includes an adapter plate 7 provided in the rectangular groove 5. The adapter plate 7 is symmetrically provided with slots 8 that adapt to the "I"-shaped guide rails 6. When the adapter plate 7 slides in the rectangular groove 5, the "I"-shaped guide rails 6 and the inner wall of the slots 8 abut against each other to form a stable area. The adapter plate 7 is provided with a silicone plate 9 that abuts against the inner diameter of the drum. At least three sets of springs 10 are provided between the adapter plate 7 and the silicone plate 9 for support, and the two ends of the springs 10 abut against the adapter plate 7 and the silicone plate 9 respectively.

[0021] Here, the rectangular groove 5 provides space for the sliding of the adapter plate 7, and the "I"-shaped guide rail 6 cooperates with the slot 8 on the adapter plate 7 to guide and limit the sliding of the adapter plate 7, ensuring the stability of the adapter plate 7 during the sliding process and preventing the adapter plate 7 from shifting.

[0022] Furthermore, when the roll is placed on the unwinding roller 3, the silicone plate 9 contacts the inner wall of the roll. The elastic force of the spring 10 allows the silicone plate 9 to better fit the inner wall of the roll, playing a buffering role and further enhancing the stability of the roll on the unwinding roller 3, avoiding shaking caused by the loose fit between the roll and the unwinding roller 3.

[0023] It should be noted that the adapter plate 7 is a replaceable design, and different specifications of adapter plate 7 can be selected according to the inner diameter of the drum. The adapter plate 7 can slide within the rectangular slide groove 5 through the cooperation of the "I"-shaped guide rail 6 and the slot 8, thereby adjusting its position according to the size of the drum's inner diameter. This achieves adaptation to drums of different sizes, solving the problem that the existing unwinding roller 3 can only adapt to one size of drum. There is no need to replace the unwinding roller 3 when changing to a different size of drum, reducing the complexity of operation, improving production efficiency, reducing equipment operating costs, and expanding the scope of application.

[0024] A lever 4 is rotatably connected to the frame 1. A drive motor 17 is fixedly connected to the frame 1, and the output end of the drive motor 17 is fixedly connected to the lever 4. When the drive motor 17 is working, the lever 4 swings along the axis of the drive motor 17. A stabilizing part for stabilizing the unwinding roller 3 is provided on the lever 4. The stabilizing part includes a hydraulic cylinder 11 fixedly installed at the end of the lever 4. A connecting plate 12 is fixedly connected to the output end of the hydraulic cylinder 11. A connecting rod 13 is rotatably connected to the connecting plate 12 through a bearing. When the hydraulic cylinder 11 is working, the connection point of the connecting rod 13 is inserted into the end of the unwinding roller 3 and forms a locking area. A limiting plate 14 is fixedly connected to the connecting rod 13. A limiting rod 15 is fixedly connected to the limiting plate 14 at the position corresponding to the adapter plate 7. A limiting hole 16 adapted to the limiting rod 15 is opened on the adapter plate 7. When the connecting rod 13 is inserted into the unwinding roller 3, the limiting rod 15 is inserted into the limiting hole 16 and forms a limiting area.

[0025] Here, the lever 4 can swing under the drive of the drive motor 17, and together with the hydraulic cylinder 11, it drives the connecting rod 13 on the connecting plate 12 to move, realizing the precise docking and separation of the connecting rod 13 on the unwinding roller 3, improving the convenience of device operation. A baffle is also installed on the connecting plate 12, which has an arc-shaped notch. The arc-shaped notch can fit the connecting rod 13. When the connecting rod 13 rotates, the inner wall of the notch is always in contact with the connecting rod 13. Through the connection between the connecting rod 13 on the connecting plate 12 and the unwinding roller 3, the axial free end of the unwinding roller 3 is effectively supported radially, solving the problem of easy shaking of the unwinding roller 3 when rotating in the traditional single-sided cantilever installation structure, improving the stability of the unwinding process, and thus ensuring the subsequent slitting accuracy.

[0026] Furthermore, after the connecting rod 13 is inserted into the unwinding roller 3, the limiting rod 15 is inserted into the limiting hole 16, thereby effectively limiting and fixing the adapter plate 7 to prevent the adapter plate 7 from sliding due to vibration or other reasons during the slitting process, ensuring the stability of the adapter plate 7 supporting the roll, and further ensuring the stability of subsequent slitting. Damping pads are provided on both the connecting rod 13 and the limiting rod 15 to improve the stability of the connection.

[0027] In this invention, during use, a suitable adapter plate 7 is selected according to the inner diameter of the roll. The adapter plate 7 is then moved to the appropriate position within the rectangular slide groove 5 via the cooperation of the "I"-shaped guide rail 6 and the slot 8. After all the adapter plates 7 are loaded onto the unwinding roller 3, the end of the unwinding roller 3 is engaged with the chuck 2, and the roll is then fitted onto the unwinding roller 3. The silicone plate 9 on the adapter plate 7 is in close contact with the inner wall of the roll under the action of the spring 10. The drive motor 17 is started, causing the lever 4 to swing to the appropriate position. The hydraulic cylinder 11 is then activated, causing the connecting plate 1 to... 2. The connecting rod 13 is extended and inserted into the end of the unwinding roller 3 to form a locking area. At the same time, the limiting rod 15 on the limiting plate 14 is inserted into the limiting hole 16 on the adapter plate 7 to form a limiting area, thereby limiting and fixing the adapter plate 7 and completing the placement of the roll. Then, the roll is cut by the slitting part in the frame 1. During unloading, the hydraulic cylinder 11 drives the connecting plate 12 and the connecting rod 13 to retract, and cooperates with the drive motor 17 to drive the lever 4 to move, so that it is misaligned with the unwinding roller 3. At this time, the unloading and reloading process is carried out.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
