Description

Technical Field

[0001] This application relates to the field of roll processing, and in particular to an automatic wrinkle-removing roller and its control method. Background Technology

[0002] Currently, guide rollers play a role in supporting or changing the winding direction and angle of the coil material in coil processing equipment. A guide roller typically includes a guide roller shaft, bearings, and a mounting base. The two ends of the guide roller shaft are rotatably connected to the mounting base through bearings. The guide roller is an indispensable component in coil material processing machinery.

[0003] In existing technologies, guide rollers are generally in the form of a smooth axis and do not have wrinkle removal function. Guide rollers with wrinkle removal function require adjusting the smooth axis guide roller to an arc-shaped roller, a medium-high roller, a flattening roller, or a figure-eight roller. Among these, the arc-shaped roller provides the best flattening effect and is the most commonly used. The roll material is wound onto the guide roller, and the arc-shaped roller effectively tensions the roll material to achieve wrinkle removal.

[0004] Regarding the aforementioned technologies, since the curved roller is constantly rotating to transport the roll material during the roll material processing, it continuously tensions and defrosts the roll material. However, when a wrinkle-free section of the roll material passes through the curved roller, it may exert a tensile force, posing a potential hazard to the roll material processing. Therefore, there is a risk that the roller may not be able to effectively switch between defrosting states, potentially causing damage to the roll material. Summary of the Invention

[0005] To address the risk of damage to the roll material caused by the inability of the passing roller to effectively switch the wrinkle removal state, this application provides an automatic wrinkle removal passing roller and its control method.

[0006] This application provides an automatic wrinkle-removing roller and its control method, which adopts the following technical solution: Firstly, an automatic wrinkle-removing roller includes: The roller shaft and the mounting plate are rotatably connected, and the roller shaft has multiple mounting grooves on its peripheral sidewall; Multiple balance wheel assemblies, one of which is installed in a mounting slot, the balance wheel assembly having a first state and a second state; in the first state, the balance wheel assembly is used for tensioning and conveying the roll material; in the second state, the balance wheel assembly is used for conveying the roll material. A drive component drives the balance wheel assembly to switch between a first state and a second state; A wrinkle sensor is used to detect the wrinkle state of the roll material and output a signal. The control center is electrically connected to both the drive assembly and the wrinkle sensor. When the wrinkle sensor detects wrinkles in the roll material, the control center receives the signal from the wrinkle sensor and controls the drive assembly to drive the balance wheel assembly to a first state; otherwise, it controls the balance wheel assembly to a second state.

[0007] By adopting the above technical solution, the wrinkle sensor can monitor the wrinkle state of the roll material in real time and adjust the balance wheel assembly to either a first or second state based on the wrinkle state. Therefore, when the roll material is wrinkle-free, the balance wheel assembly is in the second state, normally feeding the roll material; when the roll material is wrinkle-free, the balance wheel assembly is in the first state, tensioning the roll material to achieve wrinkle removal. Thus, this application can remove wrinkles based on the wrinkle state of the roll material, reducing the risk of damage from tensioning in wrinkle-free areas, thereby effectively ensuring the processing quality of the roll material.

[0008] Optionally, the plurality of mounting slots are distributed in a ring at equal intervals, and the balance wheel assembly is rotatably mounted in the mounting slot; the driving assembly drives the balance wheel assembly to rotate at different angles so that the balance wheel assembly switches between a first state and a second state.

[0009] By employing the above technical solution, the balance wheel assembly can be rotated to different angles, facilitating its switching between the first and second states. The multiple mounting slots, evenly distributed in a ring, restrict the position of the balance wheel assembly, thus improving its wrinkle-removing effect.

[0010] Optionally, the balance wheel assembly includes a mounting base and a balance wheel. The mounting base is rotatably mounted in the mounting groove, and the drive assembly drives the mounting base to rotate. A balance wheel groove is formed on the side of the mounting base near the outer wall of the roller shaft, and the balance wheel is rotatably mounted in the balance wheel groove. The side of the balance wheel away from the mounting base protrudes from the outer peripheral wall of the roller shaft. In the first state, the axis of the balance wheel assembly is not coplanar with the axis of the roller shaft; in the second state, the axis of the balance wheel assembly is parallel to the axis of the roller shaft.

[0011] By employing the above technical solution, the drive component drives the mounting base to rotate, which in turn drives the swing wheel to rotate, allowing the swing wheel to come into contact with the roll material. When the axis of the swing wheel is parallel to the axis of the roller shaft, the swing wheel does not apply lateral tension to the roll material, thus not performing wrinkle removal. When the axis of the swing wheel is coplanar with the axis of the roller shaft, the swing wheel applies lateral tension to the roll material, thereby removing wrinkles. Furthermore, adjusting the rotation angle of the swing wheel can further increase or decrease the tension on the roll material, thus enabling adaptive adjustments for different degrees of wrinkles.

[0012] Optionally, the balance wheel assembly is disposed on the periphery of both ends of the roller shaft, and the wrinkle sensor and the drive assembly are disposed at corresponding positions at both ends of the roller shaft; The wrinkle sensors and the drive assembly located at the same end of the roller shaft operate in cooperation with each other, while the wrinkle sensors and the drive assembly located at different ends of the roller shaft operate independently.

[0013] By adopting the above technical solution, firstly, tensioning the roll material at both ends of the roller can effectively improve the wrinkle removal effect. Secondly, the wrinkle sensors and drive components at both ends of the roller can independently and locally flatten the left and right ends of the roll material, further reducing the possibility of damage to the unwrinkled parts of the roll material due to tension.

[0014] Optionally, the roller shaft is hollow, and the drive assembly includes a transmission component and a drive component. The transmission component is located inside the hollow part of the roller shaft and is connected to the end of the mounting base away from the swing wheel. The drive component drives the transmission component to reciprocate, and the drive component is electrically connected to the control center.

[0015] By adopting the above technical solution, the driving component drives the transmission component to reciprocate, thereby driving the mounting base to rotate, and thus enabling the balance wheel to be at different rotation angles.

[0016] Optionally, the transmission component includes a movable seat and a plurality of racks. The movable seat is sleeved on the outside of the roller shaft and slidably connected to the roller shaft. The plurality of racks are fixed to one side of the movable seat and extend into the hollow interior of the roller shaft. The plurality of racks are arranged in a ring. The balance wheel assembly also includes gears, which are fixed to the mounting base on the side away from the balance wheel. Each rack meshes with the gear at a corresponding position, and the drive unit drives the movable base to reciprocate along the extension direction of the racks.

[0017] By adopting the above technical solution, the driving component drives the movable seat to move, the movable seat drives the rack to move, and the rack drives the gear to rotate, thereby driving the balance wheel to rotate. The displacement value of the reciprocating movement can be converted into the rotation angle value of the mounting seat, thus effectively controlling the switching of the balance wheel assembly between the first state and the second state.

[0018] Optionally, the transmission component further includes a transmission disk, which is sleeved outside the movable seat and rotatably connected to the movable seat. The driving component is fixedly connected to the mounting plate, and the output end of the driving component is connected to the transmission disk.

[0019] By adopting the above technical solution, the coordinated arrangement of the transmission disc and the movable seat enables the driving component to drive the movable seat to move back and forth in a fixed state, and ensures that the rotation of the roller shaft itself does not affect the rotation of the rack and pinion drive gear.

[0020] Optionally, the side of the mounting base is provided with a protrusion, and the mounting groove is provided with a groove at the corresponding position, and the protrusion is engaged in the groove.

[0021] By adopting the above technical solution, the protrusion can restrict the position of the mounting base, allowing the mounting base to rotate in place, thereby facilitating the adjustment of the rotation angle of the balance wheel.

[0022] Optionally, the side of the mounting base away from the roller shaft is configured as an arc surface, and the curvature of the arc surface is consistent with the curvature of the outer peripheral wall of the roller shaft.

[0023] By adopting the above technical solution, the curved surface of the mounting seat can reduce the possibility of it scratching the roll material.

[0024] Secondly, this application provides a control method for an automatic wrinkle-removing roller, which includes the following steps: S1. Activate the wrinkle sensor and drive assembly, and simultaneously cause the roller to feed the roll material; S2. Obtain the wrinkle state of the roll material through the wrinkle sensor and output a signal to the control center; S3. The control center receives and processes the signal data from the wrinkle sensor, and controls the operation of the corresponding drive components: when the wrinkle sensor detects wrinkles in the roll material, the control center controls the drive components to drive the balance wheel assembly in the first state; otherwise, the control center controls the drive components to drive the balance wheel assembly in the second state.

[0025] By adopting the above technical solution, the state of the balance wheel assembly can be adjusted according to the wrinkles of the roll material, which can effectively prevent the roll material from being stretched and damaged when it is wrinkle-free; at the same time, when there are wrinkles, the wrinkles can be effectively stretched to achieve wrinkle removal and ensure the processing quality of the roll material.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application can remove wrinkles according to the wrinkle state of the roll material, reducing the risk of the roll material being damaged by tension in areas without wrinkles, thus effectively ensuring the processing quality of the roll material; 2. Adjusting the balance wheel's axis to be parallel or non-plane with the roller's axis can change the wrinkle removal state; adjusting the balance wheel's rotation angle can further increase or decrease the tension on the roll material, thus enabling adaptive adjustment to different degrees of wrinkles. 3. Tensing the roll material at both ends of the roller can effectively improve the wrinkle removal effect; the wrinkle sensors and drive components at both ends of the roller can independently and locally flatten the left and right ends of the roll material, further reducing the possibility that the unwrinkled parts of the roll material may be damaged by tension.

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0036] It should be noted that, in the description of this application, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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 application.

[0037] This application discloses an automatic wrinkle-removing roller and its control method.

[0038] In one aspect, embodiments of this application disclose an automatic wrinkle-removing roller.

[0039] Reference Figure 1 An automatic wrinkle-removing roller includes a roller shaft 1, a mounting plate 2, a swing wheel assembly 3, a drive assembly 4, a wrinkle sensor 5, and a control center (not shown in the figure).

[0040] Reference Figure 1 and Figure 2 There are two mounting plates 2, located at both ends of the roller shaft 1. The roller shaft 1 is rotatably connected to the mounting plates 2 via bearings. Multiple mounting grooves 11 are formed on the circumferential sidewall of the roller shaft 1, and multiple swing wheel assemblies 3 are provided, with one swing wheel assembly 3 installed in one mounting groove 11. The swing wheel assembly 3 has a first state and a second state. In the first state, the swing wheel assembly 3 is used to tension and convey the roll material; in the second state, the swing wheel assembly 3 is used to convey the roll material.

[0041] In this embodiment, multiple mounting grooves 11 are distributed in a ring at equal intervals on the outer peripheral wall of the roller 1, and multiple sets are arranged in an array along the axial direction of the roller 1. Therefore, the position and number of the swing wheel assembly 3 are also determined by the position and number of the mounting grooves 11. Setting multiple sets of swing wheel assemblies 3 can effectively remove wrinkles from the roll material.

[0042] Reference Figure 3 and Figure 4 The balance wheel assembly 3 includes a mounting base 31, a balance wheel 32, and a gear 33 (see details). Figure 6 The mounting base 31 is rotatably mounted in the mounting slot 11, and the drive assembly 4 drives the mounting base 31 to rotate. Figure 5The mounting base 31 has a protrusion 311 on its side, and a corresponding groove 12 is provided in the mounting groove 11. The protrusion 311 is engaged in the groove 12. The engagement of the protrusion 311 and the groove 12 effectively enables the rotatable connection between the mounting base 31 and the mounting groove 11. The side of the mounting base 31 away from the roller 1 is set as an arc surface, and the curvature of the arc surface is consistent with the curvature of the outer peripheral wall of the roller 1. The arc surface design can reduce the possibility of damage to the roll material when the mounting base 31 comes into contact with the roll material.

[0043] Reference Figure 5 and Figure 6 The mounting base 31 has a swing wheel groove 312 on the side near the outer wall of the roller 1. The swing wheel 32 is rotatably mounted in the swing wheel groove 312. The side of the swing wheel 32 away from the mounting base 31 protrudes from the outer peripheral wall of the roller 1 to abut against the roll material. The gear 33 is fixed to the side of the mounting base 31 away from the swing wheel 32.

[0044] When the balance wheel assembly 3 is in the first state, the axis of the balance wheel 32 is not coplanar with the axis of the roller 1. That is, the balance wheel 32 is inclined relative to the extension direction of the roller 1, so that lateral tension can be applied to the roll material to complete the wrinkle removal of the roll material.

[0045] When the balance wheel assembly 3 is in the second state, the axis of the balance wheel 32 is parallel to the axis of the roller 1. At this time, the balance wheel 32 rotates under the contact of the roll to transport the roll, and the balance wheel 32 does not exert any lateral tension on the roll.

[0046] Reference Figure 1 The wrinkle sensor 5 is used to detect the wrinkle state of the roll material and output a signal. The wrinkle sensor 5 is specifically installed on the side of the swing wheel assembly 3 on the roller 1. The control center is electrically connected to both the drive assembly 4 and the wrinkle sensor 5.

[0047] When the wrinkle sensor 5 detects wrinkles in the roll material, the control center receives the signal from the wrinkle sensor 5 and controls the drive assembly 4 to drive the balance wheel assembly 3 to the first state; otherwise, it controls the balance wheel assembly 3 to the second state. Based on the wrinkle state of the roll material detected by the wrinkle sensor 5, the control center can effectively control the drive assembly 4 to drive the balance wheel assembly 3 to rotate at different angles, thus switching the balance wheel assembly 3 between the first and second states.

[0048] Therefore, when the roll material is wrinkle-free, the roll material is normally conveyed by the rollers, and the swing wheel assembly 3 is in the second state, without tensioning or wrinkle removal of the roll material. This reduces the possibility of damage to the roll material due to tension. When the roll material is wrinkle-free, the swing wheel assembly 3 is in the first state, which enables lateral tensioning and wrinkle removal of the roll material, facilitating subsequent processing.

[0049] Reference Figure 3The drive assembly 4 includes a transmission component 41, a drive component 42, an adapter component 43, and a drive nut 44.

[0050] Reference Figure 3 The roller 1 is hollow, and the transmission component 41 is located inside the hollow part of the roller 1 and is connected to the end of the mounting base 31 away from the swing wheel 32. The driving component 42 drives the transmission component 41 to reciprocate. The driving component 42 is electrically connected to the control center.

[0051] Specifically, refer to Figure 3 and Figure 4 The transmission component 41 includes a movable seat 411, multiple racks 412, and a transmission disc 413. In this embodiment, the diameter of the roller shaft 1 is reduced at both ends. The movable seat 411 is sleeved on the outside of the roller shaft 1 at the ends and slidably connected to the roller shaft 1. The multiple racks 412 are fixed to one side of the movable seat 411 and extend into the hollow interior of the roller shaft 1. The multiple racks 412 are arranged in a ring. In this embodiment, a guide hole 13 is provided on the side wall of the roller shaft 1 (combined with...). Figure 2 Multiple racks 412 are inserted through the guide holes 13 and then extend into the hollow interior of the roller shaft 1. Each rack 412 meshes with the gear 33 of the corresponding balance wheel assembly 3.

[0052] The transmission disc 413 is sleeved on the outside of the movable seat 411 and rotatably connected to the movable seat 411 via a bearing. In this embodiment, the movable seat 411 has a stepped cross-section, and the transmission disc 413 is sleeved on the outer periphery of the narrow portion of the movable seat 411 to save space and cost. The driving member 42 is fixedly connected to the mounting plate 2, and the output end of the driving member 42 is fixedly connected to the transmission disc 413 via an adapter 43. The driving member 42 drives the transmission disc 413 to move, thereby driving the movable seat 411 to reciprocate along the extension direction of the rack 412.

[0053] Reference Figure 3 and Figure 4 One end of the adapter 43 is fixedly connected to the transmission disk 413, and the other end is fixedly connected to the output end of the drive member 42. The adapter 43 is used to ensure that the drive member 42 applies a pushing or pulling force to the transmission disk 413 in the direction of the axis of the roller shaft 1, thus making the movement of the movable seat 411 on the outer periphery of the roller shaft 1 more stable. The above method will not cause the transmission disk 413 to be subjected to eccentric force, resulting in pressure between the movable seat 411 and the roller shaft 1, and ultimately preventing the movement of the movable seat 411 from being hindered.

[0054] Reference Figure 4 and Figure 7The adapter 43 includes an adapter plate 431 and two guide rods 432. The two guide rods 432 are fixedly connected to the end of the transmission disk 413 away from the roller shaft 1, and the two guide rods 432 are symmetrically arranged on both sides of the transmission disk 413. In this embodiment, the two ends of the transmission disk 413 are symmetrically provided with protrusions 414, and the guide rods 432 are fixedly connected to the protrusions 414. The guide rods 432 extend to the side of the mounting plate 2 away from the roller shaft 1 and are slidably connected to the mounting plate 2, which can be slidably connected by a linear bearing. The adapter plate 431 connects the two guide rods 432, and the output end of the drive component 42 is connected to the center of the adapter plate 431.

[0055] The adapter plate 431 has a clearance hole 433 at its center. The drive nut 44 is fixedly installed on the adapter plate 431 and is coaxial with the clearance hole 433. The output end of the drive component 42 passes through the drive nut 44 and the clearance hole 433 and is threadedly connected to the drive nut 44 (thread not shown in the thread diagram).

[0056] The drive unit 42 can be a rotary motor. The output end of the drive unit 42 rotates, thereby driving the adapter plate 431 to move left and right via a thread. The adapter plate 431 drives the guide rod 432 to move, and the guide rod 432 drives the transmission disk 413 to move along the axial direction of the roller shaft 1. The transmission disk 413 drives the movable seat 411 to slide on the outer periphery of the reduced end of the roller shaft 1, thereby causing multiple racks 412 to slide along the axial direction of the roller shaft 1. The racks 412 move while the roller shaft 1 remains stationary, so the racks 412 move relative to the roller shaft 1, thereby driving the mounting base 31 to rotate through meshing with the gear 33. The rotation of the mounting base 31 causes the balance wheel 32 to rotate, thereby adjusting the balance wheel assembly 3 to be in the first state or the second state.

[0057] The movable seat 411 is slidably connected to the roller shaft 1, and the transmission disk 413 is rotatably connected to the movable seat 411. This connection method ensures that when the roller shaft 1 rotates, the transmission disk 413 does not rotate; it can only move left and right under the action of the drive component 42. Meanwhile, the mounting base 31 and the rack 412 can move left and right under the action of the transmission disk 413 while rotating with the roller shaft 1. Therefore, it can be ensured that the rotation of the roller shaft 1 does not affect the reciprocating movement of the rack 412, thereby ensuring that the balance wheel assembly 3 can effectively switch between the first and second states.

[0058] Understandably, the displacement value of rack 412 can be converted into the rotation angle value of mounting base 31, and the rotation of mounting base 31 can adjust the rotation angle of balance wheel 32. Therefore, when the wrinkle sensor 5 detects a large number of wrinkles in the roll material, the displacement value of rack 412 can be increased, thereby increasing the rotation angle value of balance wheel 32. Adjusting the balance wheel 32 at different angles can effectively adjust the tension force on the roll material, thus effectively removing wrinkles.

[0059] Reference Figure 1 The swing wheel assembly 3 is disposed on the periphery of both ends of the roller shaft 1, and wrinkle sensors 5 and drive assemblies 4 are disposed at corresponding positions at both ends of the roller shaft 1. Among them, a group of wrinkle sensors 5 and drive assemblies 4 located at the same end of the roller shaft 1 cooperate with each other, while wrinkle sensors 5 and drive assemblies 4 located at different ends of the roller shaft 1 operate independently.

[0060] When the wrinkle sensor 5 at the left end detects a wrinkle in the left end of the roll material, the control center can control the drive assembly 4 at the left end to drive the swing wheel assembly 3 at the left end to the first state, thereby tensioning the wrinkle at the left end of the roll material. Similarly, the wrinkle sensor 5 and drive assembly 4 at the right end control the wrinkle removal of the right end of the roll material, with the left and right ends operating independently. The wrinkle sensors 5 and drive assembly 4 at both ends of the roller 1 independently and locally flatten the left and right ends of the roll material, which can further reduce the possibility of damage to the wrinkle-free parts of the roll material due to tension.

[0061] The implementation principle of this embodiment is as follows: the wrinkle sensor 5 monitors the wrinkle state of the roll material on the roller in real time and outputs the signal to the control center. When wrinkles are detected in the roll material, the control center controls the drive assembly 4 to drive the swing wheel assembly 3 to the first state. That is, the drive component 42 drives the transmission component 41 to move, thereby causing the mounting base 31 to rotate, so that the axis of the roller shaft 1 is not coplanar with the axis of the swing wheel 32, thereby removing wrinkles. When no roll material is detected, the control center controls the drive assembly 4 to drive the swing wheel assembly 3 to the second state. That is, the drive component 42 drives the transmission component 41 to move in the opposite direction, thereby causing the mounting base 31 to rotate in the opposite direction, so that the axis of the roller shaft 1 is parallel to the axis of the swing wheel 32, thereby allowing the roll material to pass normally.

[0062] Secondly, embodiments of this application disclose a control method for an automatically wrinkle-removing roller, which, based on the aforementioned automatically wrinkle-removing roller, includes the following steps: S1. Start the wrinkle sensor 5 and drive assembly 4, and at the same time cause the roller 1 to convey the roll material; S2. Obtain the wrinkle state of the roll material through the wrinkle sensor 5 and output a signal to the control center; S3. The control center receives the signal data from the wrinkle sensor 5 and processes and analyzes it, and controls the operation of the corresponding drive component 4: when the wrinkle sensor 5 detects wrinkles in the roll material, the control center controls the drive component 4 to drive the balance wheel assembly 3 to the first state; otherwise, the control center controls the drive component 4 to drive the balance wheel assembly 3 to the second state.

[0063] By using the above method, when processing the roll material, adjusting the balance wheel assembly 3 to either the first or second state according to the wrinkle condition of the roll material can effectively prevent the roll material from being stretched and damaged when it is wrinkle-free. At the same time, when there are wrinkles, it can effectively stretch the wrinkles to remove them, ensuring the processing quality of the roll material.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
