Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a swing-type floating roller structure. Background Technology

[0002] During the unwinding process of a slitting machine, tension needs to be established on the material. The main function of the floating rollers on existing slitting machines is to establish tension on the material being slitted and unwound, maintain stable unwinding tension, buffer tension fluctuations, and ensure that the unwound material from the master roll is flat, thereby ensuring the quality requirements of the material in subsequent production processes.

[0003] Currently, the floating roller mechanism on slitting machines generally includes a floating roller mounted on the frame via a swing arm and a cylinder. The swing arm is horizontally arranged and rotatably mounted on the frame via a shaft. The cylinder, maintaining a constant air pressure, drives the vertical swing arm to swing. When the material tension fluctuates, the cylinder responds by extending or retracting its piston rod. When the piston rod extends or retracts, the controller controls the rotational speed of the master roll, causing the cylinder to return to its initial equilibrium position.

[0004] While the floating roller mechanism on the current slitting machine can establish tension on the material and buffer tension fluctuations, its horizontally arranged swing arm requires a cylinder to overcome the gravity of the floating roller. This makes the cylinder's response poor when facing tension fluctuations, especially when the tension fluctuations are small. This results in the floating roller mechanism having low precision in controlling material tension and poor control over unwinding tension fluctuations.

[0005] On the other hand, the floating rollers on current slitting machines use a passive rotation method (the material drives the floating roller to rotate through friction). The width of the floating roller is generally large (more than 6 meters), and the moment of inertia of the floating roller is very large. The floating roller using the passive rotation method is also prone to scratching the material, especially film materials. Utility Model Content

[0006] The purpose of this invention is to provide a swing-type floating roller structure with good responsiveness and better control over material tension and unwinding tension fluctuations.

[0007] Another objective of this invention is to provide a swing-type floating roller structure that can effectively solve the problem that floating rollers using passive rotation in the prior art are prone to scratching materials due to their large moment of inertia.

[0008] The technical solution of this utility model is:

[0009] A swing-type floating roller structure includes:

[0010] frame;

[0011] The vertical swing arms are distributed vertically, and the upper part of the vertical swing arms is rotatably mounted on the frame via a rotating shaft;

[0012] The floating roller is rotatably mounted on the lower part of the vertical swing arm, and its weight is supported on the frame via a rotating shaft.

[0013] The cylinder, located on one side of the vertical swing arm, drives the vertical swing arm to swing. Compared with the existing floating roller mechanism, which requires the cylinder to overcome the weight of the floating roller, resulting in poor cylinder responsiveness when facing tension fluctuations and thus low material tension control accuracy and poor control effect on unwinding tension fluctuations, the swing-type floating roller structure in this solution has a vertically distributed vertical swing arm. The weight of the floating roller is supported on the frame through a rotating shaft. In this way, the cylinder does not need to overcome the weight of the floating roller. When facing tension fluctuations, the cylinder has good responsiveness and can control tension fluctuations in a timely manner, thereby improving the control accuracy of material tension and the control effect on unwinding tension fluctuations.

[0014] Preferably, the system also includes a floating roller drive mechanism, which includes a drive motor mounted on a vertical swing arm. The drive motor drives the floating roller to rotate. Compared with existing floating rollers that use passive rotation, which are prone to scratching materials due to their large moment of inertia, this solution uses a drive motor to drive the floating roller to rotate. During the unwinding process, the floating roller actively rotates, which can greatly reduce the moment of inertia of the floating roller and thus effectively prevent material scratches (e.g., preventing scratches on film materials).

[0015] Preferably, the floating roller drive mechanism also includes a transmission mechanism, through which the drive motor drives the floating roller to rotate. The transmission mechanism can be a pulley drive mechanism or a gear drive mechanism. This facilitates the arrangement of the drive motor.

[0016] Preferably, the drive motor is located between the rotating shaft and the floating roller, and in the middle or upper part of the vertical swing arm. When the vertical swing arm swings, a small portion of the weight of the floating roller and the drive motor acts on the cylinder, which needs to be overcome by the cylinder. To reduce the weight of the drive motor acting on the cylinder, this design places the drive motor in the middle or upper part of the vertical swing arm, close to the rotating shaft. When the vertical swing arm swings, the torque of the drive motor's own weight acting on the swing arm can be reduced. The cylinder further reduces the weight of the drive motor acting on the cylinder, thereby improving the cylinder's response sensitivity and enhancing the control accuracy of material tension and the control effect of unwinding tension fluctuations.

[0017] Preferably, one end of the cylinder is hinged to the frame, and the other end is hinged to the vertical swing arm, with the connection axis between the other end of the cylinder and the vertical swing arm located at the lower part of the vertical swing arm. This increases the distance between the connection axis between the other end of the cylinder and the vertical swing arm and the rotating shaft, amplifying the tension acting on the cylinder through the swing arm. This further improves the cylinder's response sensitivity, thereby enhancing the accuracy of material tension control and the control effect on unwinding tension fluctuations.

[0018] Preferably, the junction between the other end of the cylinder and the vertical swing arm is located higher than the rotating axis of the floating roller; or the junction between the other end of the cylinder and the vertical swing arm is located at the same height as the rotating axis of the floating roller; or the junction between the other end of the cylinder and the vertical swing arm is located lower than the rotating axis of the floating roller.

[0019] Preferably, the drive motor and the floating roller are located on the same side of the vertical swing arm where the drive motor is located. The side of the vertical swing arm facing the floating roller has sufficient space to install the drive motor. Therefore, this design arranges the drive motor and the floating roller on the same side of the vertical swing arm. This is beneficial in two ways: firstly, it facilitates the arrangement of the drive motor, preventing it from colliding with other components during the swinging of the vertical swing arm; secondly, it reduces the distance between the vertical swing arm and the frame, and also improves the overall structural compactness.

[0020] Preferably, the system also includes a limiting component, which comprises two limiting blocks, with the vertical swing arm positioned between the two limiting blocks. The two limiting blocks limit the swing angle of the vertical swing arm.

[0021] Preferably, the cylinder is equipped with a sensor to detect the travel of the piston rod, and the floating roller is made of carbon fiber. Compared with floating rollers made of metal, the floating roller in this solution is made of carbon fiber, which can effectively reduce the weight of the floating roller, thereby further reducing the rotational inertia of the floating roller and effectively preventing material scratches (e.g., preventing scratches on film materials).

[0022] Preferably, there are two vertical swing arms, which share the same pivot shaft; the floating roller is located between the two vertical swing arms, and the two ends of the floating roller are respectively rotatably mounted on the lower part of the corresponding vertical swing arm through bearings.

[0023] The beneficial effects of this utility model are:

[0024] Firstly, it has the characteristics of good responsiveness and better control over material tension and unwinding tension fluctuations.

[0025] Secondly, it can effectively solve the problem that floating rollers using passive rotation in existing technologies are prone to scratching materials due to their large moment of inertia. Attached Figure Description

[0038] Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a swing-type floating roller structure includes a frame 7, a vertical swing arm 1, a floating roller 2, and a cylinder 3.

[0039] The vertical swing arms 1 are vertically distributed. The upper part of the vertical swing arms 1 is rotatably mounted on the frame 7 via a rotating shaft 4. In this embodiment, the rotating shaft 4 is located at the upper end of the vertical swing arms 1.

[0040] The floating roller 2 is rotatably mounted at the lower part of the vertical swing arm 1, and its weight is supported on the frame 7 via the rotating shaft 4. In this embodiment, the floating roller 2 is rotatably mounted at the lower end of the vertical swing arm 1.

[0041] Cylinder 3 is located on one side of the vertical swing arm 1. One end of cylinder 3 is hinged to the frame 7, and the other end of cylinder 3 is hinged to the vertical swing arm 1. In this embodiment, the cylinder body end of cylinder 3 is hinged to the frame 7, and the piston rod end of cylinder 3 is hinged to the vertical swing arm 1. Cylinder 3 drives the vertical swing arm 1 to swing. In this embodiment, cylinder 3 is a cylinder that maintains a constant air pressure. Cylinder 3 receives external air pressure, and the air pressure of cylinder 3 remains constant. A sensor is provided on cylinder 3 to detect the travel of the piston rod.

[0042] In the specific work process, such as Figure 1 , Figure 2 , Figure 3 As shown, the material output from the master roll 8 on the slitting machine bypasses the floating roller 2. During the unwinding process of the master roll 8, the material tension acts on the cylinder 3 through the vertical swing arm 1. When the tightness of the material changes, the piston rod of the cylinder 3, which maintains a constant air pressure, will extend or retract. When the piston rod of the cylinder 3 extends or retracts, it can be sensed by a sensor and fed back to the controller to control the rotation speed of the master roll 8, so that the cylinder 3 returns to the initial equilibrium position. At this time, the vertical swing arm 1 is in a vertical state.

[0043] Compared to existing floating roller 2 mechanisms, which require cylinders 3 to overcome the weight of the floating roller 2, resulting in poor responsiveness of cylinders 3 when facing tension fluctuations and thus low precision in controlling material tension and poor control over unwinding tension fluctuations, the swing-type floating roller structure of this embodiment has vertically distributed vertical swing arms 1. The weight of the floating roller 2 is supported on the frame 7 via a rotating shaft 4. In this way, cylinders 3 do not need to overcome the weight of the floating roller 2. When facing tension fluctuations, cylinders 3 have good responsiveness. Even a small fluctuation in tension can generate a response in cylinders 3, which is then sensed by sensors and fed back to the controller to control the rotation speed of the master roll 8, allowing cylinders 3 to return to their initial equilibrium position. Therefore, tension fluctuations can be controlled in a timely manner, improving the precision in controlling material tension and the control effect on unwinding tension fluctuations.

[0044] Specifically, such as Figure 1 , Figure 2 As shown, there are two vertical swing arms 1. The two vertical swing arms 1 share the same rotating shaft 4. Alternatively, each of the two vertical swing arms 1 can use its own rotating shaft 4. The rotating shaft 4 is rotatably mounted on the frame 7 via bearings, and the vertical swing arms 1 are fixedly connected to the rotating shaft 4. Alternatively, the rotating shaft 4 can be fixed to the frame 7, and the vertical swing arms 1 can be rotatably connected to the rotating shaft 4 via bearings.

[0045] The floating roller 2 is located between two vertical swing arms 1, with its two ends rotatably mounted on the lower part of the corresponding vertical swing arm 1 via bearings. The rotating shaft 4 is horizontally distributed and parallel to the floating roller 2.

[0046] In one embodiment, the cylinder 3 corresponds one-to-one with the vertical swing arm 1, and the cylinder 3 drives the corresponding vertical swing arm 1 to swing.

[0047] In another embodiment, there is one cylinder 3, which drives one of the vertical swing arms 1 to swing.

[0048] Furthermore, such as Figure 1 , Figure 2As shown, a swing-type floating roller structure also includes a limiting assembly. The limiting assembly includes two limiting blocks 6, with the vertical swing arm 1 located between the two limiting blocks 6. The two limiting blocks 6 limit the swing angle of the vertical swing arm 1. In this embodiment, a rubber buffer pad is also provided on the side of the limiting block 6 facing the vertical swing arm 1.

[0049] In one embodiment, the limiting components correspond one-to-one with the vertical swing arms 1. The vertical swing arms 1 are located between the two corresponding limiting blocks 6.

[0050] In another embodiment, there is one limiting component. One of the vertical swing arms 1 is located between the two limiting blocks 6 of the limiting component.

[0051] Specific embodiment two, such as Figure 1 , Figure 2 As shown, a swing-type floating roller structure includes a frame 7, a vertical swing arm 1, a floating roller 2, a cylinder 3, and a floating roller drive mechanism 5.

[0052] The vertical swing arms 1 are vertically distributed. The upper part of the vertical swing arms 1 is rotatably mounted on the frame 7 via a rotating shaft 4. In this embodiment, the rotating shaft 4 is located at the upper end of the vertical swing arms 1.

[0053] The floating roller 2 is rotatably mounted at the lower part of the vertical swing arm 1, and its weight is supported on the frame 7 via the rotating shaft 4. In this embodiment, the floating roller 2 is rotatably mounted at the lower end of the vertical swing arm 1.

[0054] Cylinder 3 is located on one side of the vertical swing arm 1. One end of cylinder 3 is hinged to the frame 7, and the other end of cylinder 3 is hinged to the vertical swing arm 1. In this embodiment, the cylinder body end of cylinder 3 is hinged to the frame 7, and the piston rod end of cylinder 3 is hinged to the vertical swing arm 1. It drives the vertical swing arm 1 to swing. In this embodiment, cylinder 3 is a cylinder that maintains a constant air pressure. Cylinder 3 receives external air pressure, and the air pressure in cylinder 3 remains constant. A sensor is provided on cylinder 3 to detect the travel stroke of the piston rod.

[0055] The floating roller drive mechanism 5 includes a drive motor 5.1. The drive motor 5.1 is mounted on the vertical swing arm 1 and drives the floating roller 2 to rotate. In this embodiment, there is one floating roller drive mechanism 5, which is mounted on one of the vertical swing arms 1.

[0056] In the specific work process, such as Figure 1 , Figure 2 , Figure 3As shown, the material output from the master roll 8 on the slitting machine bypasses the floating roller 2. During the unwinding process of the master roll 8, the material tension is applied to the cylinder 3 through the vertical swing arm 1. At the same time, the drive motor 5.1 drives the floating roller 2 to rotate (the floating roller 2 rotates actively). When the tightness of the material changes, the piston rod of the cylinder 3, which maintains a constant air pressure, will extend or retract. When the piston rod of the cylinder 3 extends or retracts, it can be sensed by a sensor and fed back to the controller to control the rotation speed of the master roll 8, so that the cylinder 3 returns to the initial equilibrium position. At this time, the vertical swing arm 1 is in a vertical state.

[0057] Compared to existing floating roller 2 mechanisms, which require cylinders 3 to overcome the weight of the floating roller 2, resulting in poor responsiveness of cylinders 3 when facing tension fluctuations and thus low precision in controlling material tension and poor control over unwinding tension fluctuations, the swing-type floating roller structure of this embodiment has vertically distributed vertical swing arms 1. The weight of the floating roller 2 is supported on the frame 7 via a rotating shaft 4. In this way, cylinders 3 do not need to overcome the weight of the floating roller 2. When facing tension fluctuations, cylinders 3 have good responsiveness. Even a small fluctuation in tension can generate a response in cylinders 3, which is then sensed by sensors and fed back to the controller to control the rotation speed of the master roll 8, allowing cylinders 3 to return to their initial equilibrium position. Therefore, tension fluctuations can be controlled in a timely manner, improving the precision in controlling material tension and the control effect on unwinding tension fluctuations.

[0058] On the other hand, compared with the floating roller 2 in the prior art which uses a passive rotation method and is prone to scratching the material due to its large rotational inertia, this embodiment uses a drive motor 5.1 to drive the floating roller 2 to rotate. During the unwinding process of the material, the floating roller 2 rotates actively, which can greatly reduce the rotational inertia of the floating roller 2 and thus effectively prevent the material from being scratched (e.g., prevent the film material from being scratched).

[0059] Specifically, such as Figure 1 , Figure 2 As shown, there are two vertical swing arms 1. The two vertical swing arms 1 share the same rotating shaft 4. Alternatively, each of the two vertical swing arms 1 can use its own rotating shaft 4. The rotating shaft 4 is rotatably mounted on the frame 7 via bearings, and the vertical swing arms 1 are fixedly connected to the rotating shaft 4. Alternatively, the rotating shaft 4 can be fixed to the frame 7, and the vertical swing arms 1 can be rotatably connected to the rotating shaft 4 via bearings.

[0060] The floating roller 2 is located between two vertical swing arms 1, with its two ends rotatably mounted on the lower part of the corresponding vertical swing arm 1 via bearings. The rotating shaft 4 is horizontally distributed and parallel to the floating roller 2.

[0061] In this embodiment, the floating roller is made of carbon fiber. Compared with a metal floating roller, using carbon fiber can effectively reduce the weight of the floating roller, thereby further reducing its moment of inertia and effectively preventing material scratches (e.g., scratches on film materials). It should be noted that using carbon fiber as the material for the floating roller is only a preferred option in this embodiment; in actual manufacturing, the floating roller can also be made of metal or plastic, such as aluminum alloy or stainless steel.

[0062] In one embodiment, the cylinder 3 corresponds one-to-one with the vertical swing arm 1, and the cylinder 3 drives the corresponding vertical swing arm 1 to swing.

[0063] In another embodiment, there is one cylinder 3, which drives one of the vertical swing arms 1 to swing.

[0064] Furthermore, such as Figure 1 , Figure 2 As shown, a swing-type floating roller structure also includes a limiting assembly. The limiting assembly includes two limiting blocks 6, with the vertical swing arm 1 located between the two limiting blocks 6. The two limiting blocks 6 limit the swing angle of the vertical swing arm 1. In this embodiment, a rubber buffer pad is also provided on the side of the limiting block 6 facing the vertical swing arm 1.

[0065] In one implementation, the limiting component corresponds one-to-one with the vertical swing arm 1 (e.g., Figure 1 , Figure 2 (As shown). The vertical swing arm 1 is located between the two corresponding limit blocks 6.

[0066] In another embodiment, there is one limiting component. One of the vertical swing arms 1 is located between the two limiting blocks 6 of the limiting component.

[0067] Furthermore, such as Figure 1 , Figure 2 As shown, the floating roller drive mechanism 5 also includes a transmission mechanism. The drive motor 5.1 drives the floating roller 2 to rotate through the transmission mechanism. The transmission mechanism is either a pulley drive mechanism or a gear drive mechanism. This facilitates the arrangement of the drive motor 5.1.

[0068] In this embodiment, the transmission mechanism is a synchronous belt transmission mechanism 5.2. The floating roller drive mechanism 5 also includes a tensioning wheel, which is mounted on the vertical swing arm 1 and is used to tension the synchronous belt of the synchronous belt transmission mechanism 5.2.

[0069] Furthermore, such as Figure 2As shown, the drive motor 5.1 and the floating roller 2 are located on the same side of the vertical swing arm 1 where the drive motor 5.1 is located. The side of the vertical swing arm 1 facing the floating roller 2 has sufficient space to install the drive motor 5.1. Therefore, in this embodiment, the drive motor 5.1 and the floating roller 2 are arranged on the same side of the vertical swing arm 1. This is beneficial in two ways: firstly, it facilitates the arrangement of the drive motor 5.1, preventing it from colliding with other components during the swinging of the vertical swing arm 1; secondly, it reduces the distance between the vertical swing arm 1 and the frame 7, and also improves the overall structural compactness.

[0070] Furthermore, such as Figure 1 , Figure 2 As shown, the drive motor 5.1 is located between the rotating shaft 4 and the floating roller 2, and is situated in the middle or upper part of the vertical swing arm 1. When the vertical swing arm 1 swings, a small portion of the gravity of the floating roller 2 and the drive motor 5.1 acts on the cylinder 3, which needs to be overcome by the cylinder 3. To reduce the gravity of the drive motor 5.1 acting on the cylinder 3, in this embodiment, the drive motor 5.1 is positioned in the middle or upper part of the vertical swing arm 1, close to the rotating shaft 4. When the vertical swing arm 1 swings, the torque of the drive motor 5.1 acting on the swing arm can be reduced, thereby reducing the weight of the drive motor 5.1 acting on the cylinder 3, further improving the response sensitivity of the cylinder 3, and thus improving the control accuracy of material tension and the control effect of unwinding tension fluctuation.

[0071] Furthermore, such as Figure 1 As shown, the junction between the other end of cylinder 3 and the vertical swing arm 1 is located at the lower part of the vertical swing arm 1. This increases the distance between the junction between the other end of cylinder 3 and the vertical swing arm 1 and the rotating shaft 4. The tension acting on cylinder 3 through the swing arm will be amplified, thus further improving the response sensitivity of cylinder 3, thereby improving the control accuracy of material tension and the control effect of unwinding tension fluctuation.

[0072] In one implementation, such as Figure 1 As shown, the junction shaft between the other end of cylinder 3 and the vertical swing arm 1 is located higher than the rotating shaft 4 of floating roller 2. This embodiment takes into account both the installation arrangement of cylinder 3 and the responsiveness of cylinder 3. On the one hand, it facilitates the junction connection between the other end of cylinder 3 and the vertical swing arm 1; on the other hand, it allows the distance between the junction shaft between the other end of cylinder 3 and the vertical swing arm 1 and the rotating shaft 4 to be larger, so that the tension acting on cylinder 3 through the swing arm is amplified, thereby further improving the responsiveness of cylinder 3.

[0073] In another embodiment, the junction between the other end of cylinder 3 and the vertical swing arm 1 is located at the same height as the rotation axis 4 of the floating roller 2 (not shown in the figure). This embodiment can effectively increase the distance between the junction between the other end of cylinder 3 and the vertical swing arm 1 and the rotation axis 4, so that the tension acting on cylinder 3 through the swing arm is amplified, thereby further improving the response sensitivity of cylinder 3.

[0074] In the third embodiment, the junction between the other end of the cylinder 3 and the vertical swing arm 1 is located below the rotation axis 4 of the floating roller 2 (not shown in the figure). This embodiment can effectively increase the distance between the junction between the other end of the cylinder 3 and the vertical swing arm 1 and the rotation axis 4, so that the tension acting on the cylinder 3 through the swing arm is amplified, thereby further improving the response sensitivity of the cylinder 3.

[0075] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
