Description

Technical Field

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

[0002] The slitting and rewinding machine is used for slitting and rewinding aluminum foil, copper foil, plastic film and other materials. It is mainly composed of a machine body, an unwinding mechanism, a guide roller group, a slitting and edge suction mechanism, a main transmission mechanism, a double reel mechanism, and a drive motor.

[0003] During the use of the slitting and rewinding machine, after the wide material is divided into two, it is driven by two sets of feeding and rewinding mechanisms for secondary rewinding. The two sets of feeding and rewinding mechanisms are set up and down, and the two narrow materials are pulled on the surface of the two feeding and rewinding mechanisms in a staggered manner. However, the two narrow materials are prone to wrinkles on one side away from each other when the pressure is low, and cannot be flattened, which seriously affects the quality and efficiency of the secondary rewinding of the slitting machine. At the same time, the original coils are also divided into wide and narrow, and the side edges are not tightened, affecting the rewinding. At this time, the worker must adjust the pressure of one of the cylinders in any set of feeding and rewinding mechanisms, and the gap between the rewinding roller and the active roller, so as to ensure that the side of the narrow material is flattened. The control process through the electrical mechanism is very complicated. For example, it involves multiple parameter adjustments when realizing functions such as surface friction, center rewinding, and surface pressure (taper pressure). The worker inputs parameters to the machine and adjusts the working state according to the parameters to flatten the coils. Therefore, a swing arm is required to drive the rewinding mechanism for adjustment. During installation, the through hole opened in the swing arm is sleeved on the rotating shaft to achieve assembly. However, since the through hole and the rotating shaft need to be docked and the through hole and the rotating shaft are set in close proximity, it is easy to cause installation inconvenience during docking. Utility Model Content

[0004] In view of this, the present application provides a swing arm structure, a roller leveling device and a slitting and rewinding machine to solve the problem that the swing arm is difficult to install on the rotating shaft.

[0005] In a first aspect, the present application provides a swing arm structure suitable for connecting with a rotating shaft, comprising a swing arm body. The swing arm body is arranged as a long strip structure, and a through slot and a through hole penetrating two opposite side walls of the swing arm body are arranged at a first end of the swing arm body.

[0006] Among them, the through groove passes through the end wall of the first end of the swing arm body, and grooves are respectively arranged at relative positions on the two opposite side walls of the through groove, and the grooves pass through the two opposite side walls of the swing arm body. The two grooves are suitable for abutting against the rotating shaft, and the swing arm body is suitable for rotating along the circumferential direction of the rotating shaft, and the through hole is connected to the through groove.

[0007] Beneficial effects: The through groove is provided to penetrate two opposite side walls of the swing arm body and the end face of the first end of the swing arm body, enabling the first end of the swing arm body to deform in a direction away from or towards the through groove. When the swing arm body is installed on the rotating shaft, it is convenient to insert the rotating shaft into the two grooves and clamp and fix the rotating shaft, improving the installation efficiency. By adjusting the clamping force of the two grooves on the rotating shaft, the swing arm body can rotate circumferentially along the rotating shaft, and thus the angle of the swing arm body can be adjusted. The through hole is provided at the bottom of the through groove, making the first end of the swing arm body more prone to deformation for clamping and fixing the rotating shaft.

[0008] In an alternative embodiment, the through groove and the through hole are arranged along the length direction of the swing arm body. The through hole is away from the end face of the first end of the swing arm body, and the through groove is close to the end face of the first end of the swing arm body.

[0009] Beneficial effects: The through groove and the through hole are arranged on the same straight line, and the through hole is arranged on one side away from the open end of the through groove, increasing the deformation amount of the first end of the swing arm body. The connection between the rotating shaft and the groove can be realized, and it is convenient to adjust the angle of the swing arm body by adjusting the abutting force between the groove and the rotating shaft.

[0010] In an alternative embodiment, the cross-sectional area of the through hole perpendicular to the axial direction of the through hole is larger than the cross-sectional area of the through groove along the normal direction of the end face of the first end of the swing arm body.

[0011] Beneficial effects: Defining that the cross-sectional area of the through hole is larger than that of the through groove can make the position of the through hole on the swing arm body a weak area, enabling the first end of the swing arm body to deform along the position of the through hole to achieve opening and closing.

[0012] In an alternative embodiment, the groove walls of the two grooves are both arranged as arc surfaces, and the arc surfaces are adapted to fit the circumferential surface of the rotating shaft, and the two grooves are both arranged at the middle position of the through groove.

[0013] Beneficial effects: Arranging the groove walls of the grooves as arc surfaces and adapting them to the circumferential surface of the rotating shaft can increase the fitting area between the groove walls of the grooves and the circumferential surface of the rotating shaft, improving stability. At the same time, it can also avoid stress concentration and damage to the outer wall of the multi-rotating shaft.

[0014] In an alternative embodiment, the cross-section of the through hole perpendicular to the axial direction of the through hole is arranged as a circular structure, an oval-like structure or a polygonal structure.

[0015] Beneficial effects: The area of the through hole can be set in any shape, ensuring that the cross-sectional area of the through hole is larger than that of the through groove, as long as the thickness on both sides of the through hole on the swing arm body is less than the thickness on both sides of the through groove position.

[0016] In an alternative embodiment, the other two opposite side walls of the first end of the swing arm body are respectively provided with a first connection hole and a second connection hole corresponding in position, and the two grooves are adapted to abut against the rotating shaft through a connecting member inserted into the first connection hole and the second connection hole.

[0017] Advantageous effects: By providing the first connection hole and the second connection hole and connecting them through a connecting member, the limit of the first end of the swing arm body can be achieved. By tightening the connecting member, the rotating shaft can be fastened, and by loosening the connecting member, the swing of the rotating shaft can be achieved.

[0018] In an alternative embodiment, a plurality of the first connection holes and the second connection holes are respectively provided, and the plurality of the first connection holes and the second connection holes are respectively arranged in one-to-one correspondence.

[0019] Advantageous effects: By providing a plurality of the first connection holes and the second connection holes, the connection strength and connection stability can be improved by increasing the connection points.

[0020] 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.

[0021] The axial direction of the driving shaft is consistent with the axial directions of the winding roller and the rotating shaft.

[0022] A pair of the swing arm structures are provided, the rotating shaft and the winding roller are respectively arranged between the swing arm bodies of the two swing arm structures, both ends of the rotating shaft are rotatably connected to the first ends of the two swing arm bodies, and both ends of the winding roller are connected to the second ends of the two swing arm bodies.

[0024] Advantageous effects: The provided winding roller rotates through a driving element, and the material wound around the driving shaft is wound onto the winding roller. The above is the prior art and will not be elaborated here. The provided driving member is hinged to the frame and can swing. The output end of the driving member can extend and retract relative to the driving member and is hinged to the swing arm body, thereby realizing the angle adjustment of the swing arm body around the rotating shaft.

[0025] In a third aspect, the present application further provides a slitting and rewinding machine, including a roller leveling device.

[0026] Advantageous effects: Since the slitting and rewinding machine includes a roller leveling device and has the same effects as the roller leveling device, it will not be elaborated here. Description of the Drawings

[0034] The following will describe the embodiments of the present application in conjunction with Figures 1 to 3 , the embodiments of the present application will be described.

[0035] According to an embodiment of the present application, on the one hand, a swing arm structure is provided, which is adapted to be connected to the rotating shaft 7 and includes a swing arm body 1. The swing arm body 1 is set as a long strip structure, and a through groove 2 and a through hole 3 penetrating through two opposite side walls of the swing arm body 1 are provided at the first end of the swing arm body 1.

[0036] Among them, the through groove 2 penetrates the end wall of the first end of the swing arm body 1, and grooves 4 are respectively provided at relative positions on two opposite side walls of the through groove 2. The grooves 4 penetrate through two opposite side walls of the swing arm body 1. The two grooves 4 are adapted to abut against the rotating shaft 7, and the swing arm body 1 is adapted to rotate circumferentially along the rotating shaft 7. The through hole 3 is communicated with the through groove 2.

[0037] It can be understood that the provision of the through slot 2 enables the first end of the swing arm body 1 to be divided into two deformation parts. The deformation parts become strip-shaped structures, and the two deformation parts can deform towards or away from the through slot 2. Furthermore, the rotating shaft 7 is clamped and fixed by the grooves 4 provided on the two deformation parts, and by adjusting the clamping force of the two deformation parts on the rotating shaft 7, the swing of the swing arm body 1 around the rotating shaft 7 can be realized.

[0038] It should be noted that when the two deformation parts deform, the provided through hole 3 can serve as a deformation point, enabling the two deformation parts to swing with the position of the through hole 3 as the base point.

[0039] In this embodiment, the provided through slot 2 penetrates the two opposite side walls of the swing arm body 1 and the end face of the first end of the swing arm body 1, enabling the first end of the swing arm body 1 to deform in a direction away from or towards the through slot 2. When the swing arm body 1 is installed on the rotating shaft 7, it is convenient to insert the rotating shaft 7 into the two grooves 4 and clamp and fix the rotating shaft 7, improving the installation efficiency. By adjusting the clamping force of the two grooves 4 on the rotating shaft 7, the swing arm body 1 can rotate circumferentially along the rotating shaft 7, and thus the angle of the swing arm body 1 can be adjusted.

[0042] In this embodiment, the through slot 2 and the through hole 3 are arranged on the same straight line, and the through hole 3 is arranged on the side away from the open end of the through slot 2, increasing the deformation amount of the first end of the swing arm body 1, enabling the connection between the rotating shaft 7 and the groove 4, and facilitating the adjustment of the angle of the swing arm body 1 by adjusting the abutting force between the groove 4 and the rotating shaft 7.

[0046] In some embodiments, the groove walls of the two grooves 4 are both arranged as arc surfaces, and the arc surfaces are adapted to fit the peripheral surface of the rotating shaft 7, and the two grooves 4 are both arranged at the middle position of the through slot 2.

[0047] Optionally, the arc surface of the groove 4 is a circular arc structure.

[0050] Optionally, the cross-section perpendicular to the axial direction of the through hole 3 is arranged as a quasi-circular structure.

[0051] Optionally, the cross-section perpendicular to the axial direction of the through hole 3 is arranged as a polygonal structure, such as a quadrilateral structure, a pentagon structure, etc.

[0052] In this embodiment, the area of the through hole 3 can be arranged in any shape, as long as the cross-sectional area of the through hole 3 is larger than that of the through slot 2, and the thicknesses on both sides of the through hole 3 on the swing arm body 1 are smaller than the thicknesses on both sides of the through slot 2.

[0053] In some embodiments, the other two opposite side walls of the first end of the swing arm body 1 are respectively provided with a first connection hole 5 and a second connection hole 6 corresponding in position, and the two grooves 4 are adapted to abut against the rotating shaft 7 through a connecting member inserted into the first connection hole 5 and the second connection hole 6.

[0054] Optionally, the connecting member can be set as a screw or a bolt.

[0055] In this embodiment, setting the first connection hole 5 and the second connection hole 6 and connecting them through a connecting member can limit the first end of the swing arm body 1, tighten the connecting member to fasten the rotating shaft 7, and loosen the connecting member to enable the swinging of the rotating shaft 7.
