Description

Technical Field

[0001] The present application relates to the technical field of slitting and rewinding machines, and particularly relates to a swing arm structure, a roll leveling device, and a slitting and rewinding machine. Background Art

[0002] The slitting and rewinding machine is used for slitting and rewinding materials such as aluminum foil, copper foil, and plastic film. It mainly consists of a machine body, a unwind mechanism, a guide roll group, a slitting edge suction mechanism, a main drive mechanism, a double rewind shaft mechanism, and a drive motor.

[0003] During the use of the slitting and rewinding machine, after the wide-width material is divided into two, the two groups of feeding and rewinding mechanisms drive the secondary winding respectively. The two groups of feeding and rewinding mechanisms are arranged up and down, and the two narrow-width materials are tractioned in a staggered manner on the surfaces of the two feeding and rewinding mechanisms. However, the sides of the two narrow-width materials facing away from each other are prone to wrinkles when the pressure is small and cannot be flattened, seriously affecting the quality and efficiency of the secondary winding of the slitting machine. At the same time, the original coils are also divided into wide-width and narrow-width, and the sides will not be tightened, affecting the winding of the material. At this time, the worker must adjust the pressure of one of the oil cylinders in any group of feeding and rewinding mechanisms and the gap between the rewinding roll and the driving roll, so as to ensure that the sides of the narrow-width material are flattened. However, since the control process of the electrical mechanism is very complex, for example, when realizing functions such as surface friction, center winding, and surface pressure (taper pressure), multiple parameter adjustments are involved. From the time when the worker inputs the parameters to the time when the machine adjusts its working state according to the parameters to flatten the coil, the machine cannot stop during this process, resulting in that during the period from discovering the problem to solving the problem, most of the coil has been continuously released and wound, seriously affecting the winding quality and subsequent use. Summary of the Utility Model

[0004] In view of this, the present application provides a swing arm structure, a roll leveling device, and a slitting and rewinding machine to solve the problem that the gap between the rewinding roll and the driving roll needs to be adjusted during shutdown, which affects the winding quality.

[0005] In a first aspect, the present application provides a swing arm structure, including a first swing arm and a second swing arm, both of which are set as long strip structures. The first end of the first swing arm is coaxially arranged with the first end of the second swing arm, and the first swing arm rotates circumferentially around the first end of the first swing arm. A first connection hole is arranged on the side wall of the first swing arm, and a second connection hole is arranged on the side wall of the second swing arm. The first swing arm and the second swing arm are adapted to be connected by a connecting piece inserted into the first connection hole and the second connection hole.

[0006] Wherein, the cross-section of the first connection hole along its axial direction is set as an arc-shaped structure, the center of the first connection hole coincides with the rotation center of the first swing arm, and the position of the connecting piece in the first connection hole or the second connection hole is adjustable.

[0007] And / or, the cross-section of the second connection hole along its axial direction is arranged as an arc-shaped structure. The center of the circle of the second connection hole coincides with the rotation center of the first swing arm, and the position of the connecting piece in the second connection hole is adjustable.

[0008] Advantageous effects: The first swing arm and the second swing arm are coaxially arranged, and the first swing arm can rotate around the coaxial axis of the two, so that the first swing arm can rotate relative to the second swing arm, generating an angle between the two, realizing the displacement of the winding roller connected to the second end of the first swing arm, and further realizing the adjustment of the tension force. In this application, during the slitting process, the tension force can be adjusted without stopping the machine. Only by driving the first swing arm to rotate can the waste of the rolled material be avoided and the quality of the rolled material slitting be ensured. The first connection hole and the second connection hole are connected by a connecting piece, which can further enhance the connection strength between the first swing arm and the second swing arm. The position of the connecting piece in the second connection hole is adjustable, which can not only ensure the rotation action between the first swing arm and the second swing arm, but also improve the stability during the relative rotation process.

[0009] In an optional implementation manner, both the first connection hole and the second connection hole are arranged in a plurality. The plurality of first connection holes are arranged at intervals along the length direction of the first swing arm, the plurality of second connection holes are arranged at intervals along the length direction of the second swing arm, and the plurality of first connection holes and the plurality of second connection holes are arranged in one-to-one correspondence respectively.

[0010] Advantageous effects: Arranging both the first connection hole and the second connection hole in a plurality and arranging them in one-to-one correspondence respectively can further enhance the stability during the relative rotation of the first swing arm and the second swing arm.

[0011] In an optional implementation manner, the arc lengths of the plurality of first connection holes gradually increase along the length direction from the first end to the second end of the first swing arm. And / or, the arc lengths of the plurality of second connection holes gradually increase along the length direction from the first end to the second end of the second swing arm.

[0012] Advantageous effects: Since when the first swing arm rotates, the swing arc length along the length direction from the first end to the second end of the second swing arm gradually increases, therefore, the arc length of the first connection hole and / or the plurality of second connection holes gradually increasing along the length direction from the first end to the second end of the second swing arm can avoid the limit caused by insufficient length.

[0013] In an optional implementation manner, the first swing arm is in contact with the second swing arm, and the side wall of the first swing arm is in sliding contact with the side wall of the second swing arm.

[0014] Advantageous effects: The first swing arm and the second swing arm cooperate with each other to slide, which can enhance the stability of the first swing arm and the second swing arm during the relative rotation process.

[0015] In an alternative embodiment, a notch is provided at a corner position of a side wall away from a first end of the second swing arm, a fixing block is provided on a side wall of the first swing arm, and the fixing block corresponds to the notch position.

[0016] Beneficial effects: The provided fixing block can provide a fulcrum for the driving member, and by adjusting the distance between the fixing block and the first swing arm, the rotation angle of the first swing arm can be adjusted, thereby realizing the adjustment of the distance between the driving roller and the winding roller, and finally realizing the adjustment of the tension force.

[0017] In an alternative embodiment, the connecting member includes a bolt and a nut, and the bolt passes through the first connecting hole and the second connecting hole and is threadedly connected to the nut.

[0018] Beneficial effects: The connection method of the bolt and the nut can not only quickly connect, but also adjust the tightening force at any time, improving the adaptability.

[0019] In a second aspect, the present application further provides a roller leveling device, including a rotating shaft, a winding roller, a driving roller and a swing arm structure. The axial direction of the driving roller is consistent with the axial directions of the winding roller and the rotating shaft. Wherein, a first end of the rotating shaft sequentially passes through a first end of a first swing arm and a first end of a second swing arm of the swing arm structure, and the first end of the first swing arm can rotate circumferentially along the rotating shaft, and the first end of the second swing arm is relatively fixed to the circumferential direction of the rotating shaft.

[0020] Beneficial effects: The driving roller and the winding roller can realize the transmission of the rolled material. By rotating around the rotating shaft, the first swing arm can adjust the distance between the driving roller and the winding roller, thereby realizing the adjustment of the tension force during the transmission of the rolled material, avoiding the side edge of the rolled material not being tightened after being slit, and thus ensuring the slitting quality.

[0021] In an alternative embodiment, a third swing arm is further included. A second end of the rotating shaft passes through a first end of the third swing arm, and the first end of the third swing arm can rotate circumferentially along the rotating shaft. Two ends of the winding roller are respectively connected to a second end of the first swing arm and a second end of the third swing arm.

[0022] Beneficial effects: The third swing arm can play an effect of assisting in fixing the winding roller and enhancing the structural strength.

[0024] Alternatively, the driving member is disposed on the fixed block, and the driving end of the driving member is disposed on the first swing arm. The driving member is adapted to drive the first swing arm to rotate circumferentially along the rotating shaft.

[0025] Advantageous effects: By adjusting the distance between the fixed block and the first swing arm through the driving member, on the premise that the second swing arm is circumferentially fixed, the swinging action of the first swing arm can be realized, and then the adjustment of the tension force can be realized.

[0026] In a third aspect, the present application further provides a slitting and rewinding machine, including a roll leveling device.

[0027] Since the slitting and rewinding machine includes a roll leveling device and has the same effects as the roll leveling device, it will not be elaborated here. Description of the Drawings

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0037] The following will describe the embodiments of this application in conjunction with Figures 1 to 5 , the embodiments of this application will be described.

[0038] According to an embodiment of this application, on the one hand, a swing arm structure is provided, which includes a first swing arm 1 and a second swing arm 2, both of which are arranged in a long strip structure. The first end of the first swing arm 1 and the first end of the second swing arm 2 are coaxially arranged, and the first swing arm 1 rotates circumferentially around the first end of the first swing arm 1. A first connection hole 3 is provided on the side wall of the first swing arm 1, and a second connection hole 4 is provided on the side wall of the second swing arm 2. The first swing arm 1 and the second swing arm 2 are adapted to be connected by a connecting member inserted into the first connection hole 3 and the second connection hole 4.

[0039] Wherein, the cross-section of the first connection hole 3 along its axial direction is arranged in an arc structure. The center of the first connection hole 3 coincides with the rotation center of the first swing arm 1, and the position of the connecting member in the first connection hole 3 or the second connection hole 4 is adjustable.

The center of the second connection hole 4 coincides with the rotation center of the first swing arm 1, and the position of the connecting member in the second connection hole 4 is adjustable.

[0041] It can be understood that the second swing arm 2 is in a fixed state. Therefore, when the first swing arm 1 rotates circumferentially around the first end of the first swing arm 1, it is the relative rotation of the first swing arm 1 with respect to the second swing arm 2, thereby adjusting the tension of the winding material between the driving roller 8 and the winding roller 7.

[0042] In this embodiment, the first swing arm 1 and the second swing arm 2 are coaxially arranged, and the first swing arm 1 can rotate around the coaxial axis of the two, so that the first swing arm 1 can rotate relative to the second swing arm 2, generating an angle between the two, realizing the displacement of the winding roller 7 connected to the second end of the first swing arm 1, and further realizing the adjustment of the tension force. In the present application, during the slitting process, the tension force can be adjusted without stopping the machine. Only by driving the first swing arm 1 to rotate can the waste of the coiled material be avoided and the quality of the coiled material slitting be ensured. The first connection hole 3 and the second connection hole 4 are connected by a connecting piece, which can further enhance the connection strength between the first swing arm 1 and the second swing arm 2. The position of the connecting piece in the second connection hole 4 is adjustable, which can ensure the rotation action between the first swing arm 1 and the second swing arm 2 and improve the stability during the relative rotation process.

[0046] Optionally, the arc lengths of the multiple second connection holes 4 gradually increase along the length direction from the first end to the second end of the second swing arm 2.

[0047] In this embodiment, since when the first swing arm 1 rotates, the swing arc length along the length direction from the first end to the second end of the second swing arm 2 gradually increases, therefore, the arc lengths of the first connection hole 3 and / or the multiple second connection holes 4 gradually increasing along the length direction from the first end to the second end of the second swing arm 2 can avoid the limit caused by insufficient length.

[0048] In some embodiments, the first swing arm 1 is in contact with the second swing arm 2, and the side wall of the first swing arm 1 is in sliding contact with the side wall of the second swing arm 2.

[0049] In this embodiment, the first swing arm 1 and the second swing arm 2 cooperate with each other to slide, which can enhance the stability of the first swing arm 1 and the second swing arm 2 during the relative rotation process.

[0050] In some embodiments, a notch is provided at a corner position on the side wall away from the first end of the second swing arm 2. A fixing block 5 is provided on the side wall of the first swing arm 1, and the fixing block 5 corresponds to the notch position.

[0051] In this embodiment, the provided fixing block 5 can provide a fulcrum for the driving member. By adjusting the distance between the fixing block 5 and the first swing arm 1, the rotation angle of the first swing arm 1 can be adjusted, thereby realizing the adjustment of the distance between the driving roller 8 and the winding roller 7, and finally realizing the adjustment of the tension force.

[0052] In some embodiments, the connecting member includes a bolt and a nut. The bolt passes through the first connecting hole 3 and the second connecting hole 4 and is threadedly connected to the nut.

[0053] In this embodiment, the connection method of the bolt and the nut can not only connect quickly, but also adjust the tightening force at any time, improving the adaptability.

[0054] According to an embodiment of the present application, on the other hand, a roller leveling device is also provided, including a rotating shaft 6, a winding roller 7, a driving roller 8 and a swing arm structure. The axial direction of the driving roller 8 is the same as the axial directions of the winding roller 7 and the rotating shaft 6. Among them, the first end of the rotating shaft 6 sequentially passes through the first end of the first swing arm 1 of the swing arm structure and the first end of the second swing arm 2, and the first end of the first swing arm 1 can rotate circumferentially along the rotating shaft 6, and the first end of the second swing arm 2 is relatively fixed to the rotating shaft 6 in the circumferential direction.

[0055] Optionally, a through hole is provided at the first end of the second swing arm 2. The first end of the rotating shaft 6 passes through the through hole. A fixing hole 9 is provided on the inner wall of the through hole. A bolt is threadedly connected in the fixing hole 9. By rotating the bolt, the end face of the bolt can be made to abut against the outer wall of the rotating shaft 6, thereby realizing the relative fixation of the second swing arm 2 and the rotating shaft 6.

[0056] Optionally, the rotating shaft 6 is arranged on the machine body.

[0057] Optionally, a driving element, such as a motor, is provided at one end of the winding roller 7, or the motor drives a transmission assembly to drive the winding roller 7 to rotate, thereby realizing the winding of the coil material on the driving roller 8.

[0058] In this embodiment, the driving roller 8 and the winding roller 7 can realize the transmission of the coil material. The first swing arm 1 can rotate around the rotating shaft 6 to adjust the distance between the driving roller 8 and the winding roller 7, thereby realizing the adjustment of the tension force during the transmission of the coil material, avoiding the side edge of the coil material not being tightened after being slit, and thus ensuring the slitting quality.

[0059] In some embodiments, a third swing arm 10 is further included. The second end of the rotating shaft 6 penetrates through the first end of the third swing arm 10, and the first end of the third swing arm 10 can rotate circumferentially along the rotating shaft 6. Both ends of the winding roller 7 are respectively connected to the second end of the first swing arm 1 and the second end of the third swing arm 10.

[0060] Optionally, the third swing arm 10 can be discarded, and a pair of swing arm structures can be provided.

[0061] It should be noted that the third swing arm 10 and the fixed block 5 can be hinged to the output end of the oil cylinder, and the bottom of the oil cylinder is hinged to the machine body, so that the parameter leveling can be realized through the electrical mechanism. The fixed block 5 is connected to the first swing arm 1 by bolts. The main highlight of this application is a solution that can be manually adjusted without stopping the machine. And the manual adjustment is a fine adjustment, which is realized on the premise that there is a certain amount of movement at the output end of the oil cylinder.

[0062] In this embodiment, the third swing arm 10 can play a role in assisting in fixing the winding roller 7 and enhancing the structural strength.
