[0034] This section will combine Figures 1 to 10 Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0035] In the description of the present application, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0036] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] like Figure 1 As shown, an embodiment of the present application provides an unwinding device, which includes an upper support assembly 100, a lower support assembly 300 and an unwinding assembly 501. The unwinding assembly 501 is used to load the coil. During the rotation of the unwinding assembly 501, the unwinding end of the coil can be separated from the main part of the coil due to gravity, thereby realizing automatic unwinding. Since the unwinding end of the coil needs to move to a target position in a direction away from the upper support assembly 100 and the lower support assembly 300, when the coil is loaded on the unwinding assembly 501 in different states, the unwinding end of the coil moves from the top or bottom of the main part of the coil to the target position, that is, upper unwinding and lower unwinding.

[0038] Furthermore, when the coil is unrolled, the unrolled end of the coil tends to tilt upward, and the upper support assembly 100 is used to press the unrolled end of the coil to ensure that the unrolled end moves to the target position. When the coil is unrolled, the unrolled end of the coil tends to fall downward, and the lower support assembly 300 is used to lift the unrolled end of the coil to ensure that the unrolled end moves to the target position.

[0039] The upper support assembly 100 and the lower support assembly 300 are combined and arranged through a transmission component, which reduces the complexity of the unwinding device, saves space, and improves the integrity of the device.

[0040] like Figure 2 and Figure 3 As shown, in some examples, the upper support assembly 100 includes a first rotating support assembly 101 and an upper support driver 102, and the upper support driver 102 drives the first rotating support assembly 101 to rotate so as to approach the unwinding assembly 501 or to move away from the unwinding assembly 501. When the unwinding assembly 501 is loaded with a coil, the first rotating support assembly 101 rotates away from the unwinding assembly 501 to avoid a space for loading the coil, thereby avoiding structural interference between the first rotating support assembly 101 and the coil. When the coil is unwinding, the first rotating support assembly 101 rotates close to the unwinding assembly 501, thereby contacting and pressing the unwinding end of the coil.

[0041] Further, the first rotating support assembly 101 includes a first transmission component 103 and an upper support arm 104, the first transmission component 103 is fixedly connected to the upper support arm 104, and the upper support arm 104 is used to press the unwinding end of the coil. When the first transmission component 103 rotates, the upper support arm 104 rotates together, thereby approaching the unwinding assembly 501, or moving away from the unwinding assembly 501. The first transmission component 103 is connected to the upper support driver 102, and the upper support driver 102 drives the first transmission component 103 and the upper support arm 104 to rotate.

[0042] like Figure 4 As shown, in some examples, the upper support arm 104 includes a first extension portion 201, a first bending portion 202 and a pressing portion 203, one end of the first extension portion 201 is fixedly connected to the first transmission component 103, and the first extension portion 201 extends toward the top of the coil. The other end of the first extension portion 201 is connected to one end of the pressing portion 203 through the first bending portion 202, so that the first extension portion 201 and the pressing portion 203 are at an angle, which is conducive to the other end of the pressing portion 203 being closer to the coil, thereby forming a pressing effect on the unwinding end of the coil.

[0043] like Figure 2 and Figure 5 As shown, the lower support assembly 300 includes a second rotating support assembly 301 and a lower support driver 302. The lower support driver 302 drives the second rotating support assembly 301 to rotate so as to approach the unwinding assembly 501 or to move away from the unwinding assembly 501. When the unwinding assembly 501 is loaded with coils, the second rotating support assembly 301 rotates away from the unwinding assembly 501 to avoid the space for loading the coils, thereby avoiding structural interference between the second rotating support assembly 301 and the coils. When the coils are unwinding, the second rotating support assembly 301 rotates close to the unwinding assembly 501, thereby contacting and lifting the unwinding end of the coils.

[0044] Furthermore, the second rotating support assembly 301 includes a second transmission component 303 and a lower support arm 304. The second transmission component 303 is fixedly connected to the lower support arm 304. The lower support arm 304 is used to lift the unwinding end of the coil.

[0045] The second transmission component 303 and the first transmission component 103 are mutually sleeved to form a coaxial integral structure, and under the premise that the first transmission component 103 and the second transmission component 303 can rotate independently, space is saved and the complexity of the unwinding device is reduced. When the second transmission component 303 rotates, the lower support arm 304 rotates together, thereby approaching the unwinding assembly 501 or moving away from the unwinding assembly 501. The second transmission component 303 is connected to the lower support driver 302, and the lower support driver 302 drives the second transmission component 303 and the lower support arm 304 to rotate.

[0046] like Figure 6 and Figure 7 As shown, in some examples, the lower support arm 304 includes a second extension portion 401, a second bending portion 402 and a lifting portion 403, one end of the second extension portion 401 is fixedly connected to the second transmission component 303, and the second extension portion 401 extends toward the bottom of the coil. The other end of the second extension portion 401 is connected to one end of the lifting portion 403 through the second bending portion 402, so that the second extension portion 401 and the lifting portion 403 are at an angle, which is conducive to the other end of the lifting portion 403 being closer to the coil, thereby forming a lifting effect on the unwinding end of the coil.

[0047] It is worth noting that, since the first transmission component 103 and the second transmission component 303 are coaxially sleeved, there is an axial position difference between the connection position of the first extension portion 201 and the first transmission component 103 and the connection position of the second extension portion 401 and the second transmission component 303. In order to make the pressing portion 203 and the lifting portion 403 correspond to each other, the second extension portion 401 is tilted, so that the part of the second extension portion 401 connected to the second transmission component 303 is misaligned with the lifting portion 403, ensuring that the lifting portion 403 and the pressing portion 203 are approximately in the same axial plane of the first transmission component 103 and the second transmission component 303.

[0048] It is understandable that the first extending portion 201 may also be arranged to be inclined to ensure that the lifting portion 403 and the pressing portion 203 are approximately in the same axial plane of the first transmission component 103 and the second transmission component 303 .

[0049] In some examples, the first transmission component 103 includes a transmission shaft, the second transmission component 303 includes a transmission sleeve, the second transmission component 303 is sleeved on the first transmission component 103 to form a rotational connection, and the transmission shaft and the transmission sleeve can rotate independently. Alternatively, the first transmission component 103 includes a transmission sleeve, the second transmission component 303 includes a transmission shaft, and the first transmission component 103 is sleeved on the second transmission component 303.

[0050] Furthermore, the length of the transmission shaft is greater than the length of the transmission sleeve, and the transmission shaft supports the transmission sleeve. When the position of the transmission shaft is fixed, the position of the transmission sleeve is also relatively fixed. Specifically, the unwinding device includes a bracket, which is at least set up near both ends of the transmission shaft, and a part of the bracket is connected to the unwinding assembly 501, and the other part is fixed to the ground to ensure the integrity of the unwinding device.

[0051] It can be understood that the bracket is rotatably connected to the transmission shaft. On the one hand, the bracket stabilizes the transmission shaft at a set height; on the other hand, the bracket does not hinder the rotation of the transmission shaft. In addition, a bracket is also mounted on the transmission sleeve, and the transmission sleeve is rotatably connected to the corresponding bracket, and the bracket is connected to the unwinding component 501.

[0052] In some examples, the pressing portion 203 of the upper support arm 104 or the lifting portion 403 of the lower support arm 304 needs to contact the unwinding end of the coil to achieve the pressing or lifting effect. To prevent the pressing portion 203 from damaging the unwinding end of the coil during the contact process, a first rolling component 404 is provided at the end of the pressing portion 203; similarly, to prevent the lifting portion 403 from damaging the unwinding end of the coil during the contact process, a first rolling component 404 is also provided at the end of the lifting portion 403.

[0053] Furthermore, a certain installation space is reserved at the ends of the lifting part 403 and the pressing part 203, and sockets are reserved on the physical structure on both sides of the installation space. The roller structure is arranged in the installation space, and the roller shaft passes through the hollow part and the socket of the roller structure, so that the roller structure is installed at the ends of the lifting part 403 and the pressing part 203, and the roller structure forms rolling contact with the unwinding end of the coil to avoid damaging the unwinding end of the coil.

[0054] In some examples, the first rotating support assembly 101 includes a force transmission component 405, which is fixedly connected to the first transmission component 103 and extends a certain distance to the outside of the first transmission component 103. When the force transmission component 405 rotates, it drives the first transmission component 103 and the upper support arm 104 to rotate, and the first transmission component 103 is connected to the upper support driver 102 through the force transmission component 405.

[0055] The upper support driver 102 adopts a structure for outputting linear motion, and the output end of the upper support driver 102 is rotationally connected to the force transmission component 405, and the force transmission component 405 provides a force arm for the upper support driver 102, thereby converting the output linear motion into the rotational motion of the force transmission component 405. Specifically, the upper support driver 102 adopts a structure such as an oil cylinder, an air cylinder, or an electric push rod.

[0056] Similarly, the second rotating support assembly 301 also includes a force transmission component 405 , which is fixedly connected to the second transmission component 303 and extends a certain distance to the outside of the second transmission component 303 . The second transmission component 303 is connected to the lower support driver 302 via the force transmission component 405 .

[0057] The lower support driver 302 also adopts a structure for outputting linear motion, and the output end of the lower support driver 302 is rotationally connected with the force transmission component 405, and the force transmission component 405 provides a force arm for the lower support driver 302. Specifically, the lower support driver 302 adopts a structure such as an oil cylinder, an air cylinder, or an electric push rod.

[0058] like Figure 8As shown, in some examples, the unwinding assembly 501 includes a rotating shaft assembly, the coil is loaded on the rotating shaft assembly, and the rotation of the rotating shaft assembly drives the coil to be unwound.

[0059] Furthermore, the rotating shaft assembly includes an unwinding shaft 502 and an unwinding driver 503. The unwinding shaft 502 is inserted into the hollow part of the coil, thereby completing the loading of the coil. The unwinding driver 503 drives the unwinding shaft 502 to rotate, thereby driving the coil to rotate.

[0060] It is understandable that in order to move the unwinding end of the coil to the target position, the coil needs to be unwinded upward or downward under different loading conditions, and the unwinding upward and downward of the coil requires the coil to rotate in different directions, so the unwinding driver 503 can output bidirectional rotational motion. Specifically, the unwinding driver 503 uses a motor that can rotate forward and reverse.

[0061] like Figure 8 As shown, in some examples, the rotating shaft assembly includes a transmission mechanism, which connects the unwinding shaft 502 and the unwinding driver 503 . The unwinding driver 503 transmits torque to the unwinding shaft 502 through the transmission mechanism, thereby driving the unwinding shaft 502 to rotate.

[0062] Specifically, the transmission mechanism includes a reducer 507 and a gear set 508. The unwinding driver 503 is connected to the input end of the reducer 507 through a coupling, and the output end of the reducer 507 is connected to the first gear. Then, the unwinding driver 503 transmits the torque to the first gear through the reducer 507. The outer side of the unwinding shaft 502 is fixedly connected to the second gear, and the first gear meshes with the second gear to form a gear set 508, thereby finally transmitting the torque to the unwinding shaft 502.

[0063] It is understandable that other gears may be added between the first gear and the second gear according to specific needs to ensure the transmission of torque.

[0064] In some examples, to prevent the coil and the unwinding shaft 502 from rotating relative to each other, the unwinding shaft 502 includes a plurality of internal expansion components, the internal expansion components including internal expansion plates and guide blocks, the internal expansion plates contacting the inner wall of the coil. The guide blocks are slidably connected to the internal expansion plates, and the guide blocks extend radially along the unwinding shaft 502, and the internal expansion plates can move radially along the guide blocks, so that the internal expansion plates are close to the inner wall of the coil, or away from the inner wall of the coil.

[0065] Among them, when the unwinding shaft 502 is loaded with a coil, each inner expansion plate contracts in the radial direction to reduce the radial size of the unwinding shaft 502, thereby facilitating the loading of the coil; when the coil is loaded, each inner expansion plate expands in the radial direction to increase the radial size of the unwinding shaft 502, so that the inner expansion plates support the inner wall of the coil, thereby avoiding relative rotation between the coil and the unwinding shaft 502, thereby ensuring the effectiveness of rotational unwinding.

[0066] like Fig. 9 As shown, in some examples, the unwinding assembly 501 includes a base 504 and a movable platform assembly, the base 504 is fixed to the ground, and the movable platform assembly includes a platform body 505, and the platform body 505 can move on the base 504. Among them, the unwinding shaft 502, the transmission mechanism and the unwinding driver 503 are installed on the platform body 505. When the platform body 505 moves on the base 504, the whole formed by the unwinding shaft 502, the transmission mechanism and the unwinding driver 503 moves relative to the ground, so that the unwinding shaft 502 is close to the storage position of the coiled material, or away from the storage position of the coiled material. When the unwinding shaft 502 moves to the storage position close to the coiled material, it is convenient for the loading of the coiled material.

[0067] At the same time, part of the bracket supporting the transmission shaft is arranged on the platform body 505, the bracket supporting the transmission sleeve is arranged on the platform body 505, and the upper support driver 102 and the lower support driver 302 are also arranged on the platform body 505. When the platform body 505 moves, the upper support assembly 100 and the lower support assembly 300 move together with the unwinding shaft 502 to ensure the movement integrity of the unwinding device.

[0068] Furthermore, a guide assembly is provided between the platform body 505 and the base 504, and the platform body 505 moves along the guide assembly. The guide assembly includes a slider and a slide rail that fit together, the slide rail is provided on the base 504, and the slider is provided on the platform body 505, or the slide rail is provided on the platform body 505, and the slider is provided on the base 504. Therefore, the platform body 505 moves along the extension direction of the slide rail, and specifically, the slide rail extends in the axial direction of the unwinding shaft 502.

[0069] In addition, the movable platform assembly includes a platform driver 506, which is connected to the platform body 505, and drives the platform body 505 to move relative to the base 504. Specifically, the platform driver 506 can adopt any structure that outputs linear motion, such as an oil cylinder, an air cylinder, and an electric push rod. The fixed end of the platform driver 506 is connected to the base 504, and the output end of the platform driver 506 is rotatably connected to the platform body 505.

[0070] like Fig.10 As shown, in some examples, the rotating shaft assembly includes a positioning assembly 601, which is connected to the outside of the unwinding shaft 502 and can move axially along the unwinding shaft 502. When the end surface of the coil contacts the positioning assembly 601, the coil reaches a preset position and can be unwound subsequently.

[0071] Furthermore, the positioning assembly 601 includes a positioning driver 602 and an abutting positioning assembly 601 , and the positioning driver 602 drives the abutting positioning assembly 601 to move to a target position so as to determine the axial position of the coil.

[0072] The output end of the positioning driver 602 is provided with a positioning plate, and a plurality of abutting positioning components 601 are provided, each of which is arranged on the positioning plate.

[0073] Meanwhile, the positioning assembly 601 includes a mounting structure, and the positioning driver 602 is disposed on the mounting structure. The mounting structure includes a plurality of guide holes, and the positioning plate is provided with a plurality of guide rods, which are inserted into the guide holes to guide the abutting positioning assembly 601. Specifically, the guide rods extend in the axial direction of the unwinding shaft 502.

[0074] In some examples, the abutment positioning assembly 601 includes a second rolling component 603 and a support 604. The support 604 is installed on the positioning plate, and the support 604 is provided with an installation space. The second rolling component 603 can roll in the installation space and form a rolling contact with the end surface of the coil to avoid scratching the end surface of the coil.

[0075] During use, the platform body 505 moves so that the unwinding shaft 502 is close to the storage position of the coil, and the coil is sleeved on the unwinding shaft 502 until the end surface of the coil contacts the second rolling component 603, and the internal expansion plate fixes the coil to the unwinding shaft 502 in an internal expansion manner, and the platform body 505 is reset to prepare for unwinding. When the coil needs to be unwound, the unwinding driver 503 drives the unwinding shaft 502 to rotate through the transmission mechanism, and the upper support driver 102 drives the upper support arm 104 to press the unwinding end of the coil through the first transmission component 103 to ensure that the unwinding end can reach the target position. When the coil needs to be unwound, the unwinding driver 503 drives the unwinding shaft 502 to rotate through the transmission mechanism, and the lower support driver 302 drives the lower support arm 304 to lift the unwinding end of the coil through the second transmission component 303 to ensure that the unwinding end can reach the target position, thereby completing the entire unwinding process.
