The embodiment integrates the loading mechanism 2, the limiting mechanism 3 and the driving mechanism 4, aims to realize the stable support and accurate control of the steel coil 5, and ensures the stability and safety of the unwinding process. Specifically, the embodiment drives the loading mechanism 2 and the limiting mechanism 3 through the driving mechanism 4, so that the unwinding and pressing of the steel coil 5 can be carried out synchronously, effectively avoids the loosening or displacement of the steel coil 5 during the unwinding process, improves the stability and quality of the unwinding, reduces the operation steps and the complexity of the equipment, improves the production efficiency, and solves the problem that the existing unwinding device only uses the simple limiting roller to limit the steel coil 5, and there may be a gap between the steel coil 5 and the limiting roller during the actual unwinding process, which leads to the lifting of the steel coil 5 and affects the normal unwinding work.
[0029] In a feasible implementation mode, the operator first loads the steel coil 5 onto the loading mechanism 2, and ensures that the position of the steel coil 5 is correct and stable. Then the driving mechanism 4 is started, the driving mechanism 4 starts to output power and drives the loading mechanism 2 to rotate, so that the steel coil 5 wound on the loading mechanism 2 is unwound; at the same time, under the driving of the driving mechanism 4, the limiting mechanism 3 moves along the predetermined direction, gradually approaches the steel coil 5, and applies pressure to the steel coil 5, so as to prevent the steel coil 5 from loosening or displacing during the unwinding process. The loading mechanism 2 and the limiting mechanism 3 work cooperatively under the driving of the driving mechanism 4, the loading mechanism 2 continuously rotates to unwind the steel coil 5, and the limiting mechanism 3 continuously adjusts the position to press the steel coil 5, so as to ensure the stability and safety of the unwinding process; when the steel coil 5 is completely unwound, the driving mechanism 4 stops working, and the limiting mechanism 3 keeps the pressing state of the remaining steel coil 5, so as to ensure the stability and safety of the steel coil 5.
[0030] In some embodiments, the loading mechanism 2 comprises a main shaft 21 for loading the steel coil 5 and a transmission gear 22 coaxially connected to the main shaft 21, and the driving mechanism 4 is connected to the transmission gear 22 in a transmission mode. It should be explained that the main shaft 21 and the transmission gear 22 are coaxially connected, aiming to ensure that the two are synchronous during rotation, and the driving mechanism 4 starts to drive the main shaft 21 to rotate through the transmission gear 22.
[0031] In some embodiments, the driving mechanism 4 comprises a driving motor 41 and a speed reducer 42, an output end of the driving motor 41 is connected to an input end of the speed reducer 42; wherein an output end of the speed reducer 42 is provided with an output gear 43, the output gear 43 and the transmission gear 22 are provided with a synchronous tooth belt 44 therebetween, the synchronous tooth belt 44 is arranged around and engaged with the output gear 43 and the transmission gear 22. Optionally, the driving motor 41 can be a bidirectional motor. Optionally, the driving motor 41 can be a unidirectional motor, a clutch is arranged between the driving motor 41 and the speed reducer 42, the clutch is used for controlling the power transmission connection or disconnection between the driving motor 41 and the speed reducer 42, the clutch can be a mechanical clutch or an electrical clutch, which aims to prevent damage to the driving motor 41 caused by the reverse rotation of the transmission gear 22.
[0032] It needs to be explained that the speed reducer 42 can reduce the high rotating speed of the driving motor 41 and amplify the torque through gear transmission or planetary gear transmission, and the speed reduction ratio of the speed reducer 42 can be designed according to specific process requirements to meet the demand of low speed and high torque. The synchronous tooth belt 44 is a kind of transmission belt with tooth shape, which realizes the power transmission through the engagement with the output gear 43 and the transmission gear 22.
[0033] In some embodiments, the limiting mechanism 3 comprises a connecting piece 31 slidably connected to the rack 1 along a first direction, and a first limiting piece 32 connected to the connecting piece 31, a side of the connecting piece 31 facing the transmission gear 22 is provided with a tooth structure 311 along the first direction, the tooth structure 311 is engaged with the transmission gear 22; wherein the first limiting piece 32 and the main shaft 21 form a first limiting space for clamping in the radial direction of the steel coil 5, when the driving mechanism 4 outputs power, the transmission gear 22 is driven to rotate, the transmission gear 22 drives the connecting piece 31 and the first limiting piece 32 to move along the first direction through the tooth structure 311, so as to reduce the first limiting space.
[0034] It needs to be explained that the radial dimension of the steel coil 5 gradually decreases as the unwinding progresses after being loaded on the main shaft 21, the first limiting piece 32 in the embodiment can gradually approach the steel coil 5 as the unwinding operation progresses, so as to compensate for the decreasing radial dimension of the steel coil 5 as the unwinding operation progresses. It can be understood that the first limiting piece 32 and the main shaft 21 form a first limiting space for clamping in the radial direction of the steel coil 5, by outputting power by the driving mechanism 4, the transmission gear 22 is driven to rotate, and then the connecting piece 31 and the first limiting piece 32 are driven to move along the first direction through the tooth structure 311, so as to reduce the first limiting space, thereby compacting the steel coil 5.
[0035] In a feasible implementation process, the driving mechanism 4 outputs power, drives the main shaft 21 to rotate through the transmission gear 22, and gradually unwinds the steel coil 5 wound on the main shaft 21; under the driving of the driving mechanism 4, the transmission gear 22 rotates, drives the connecting piece 31 and the first limiting piece 32 to move along the first direction through the tooth structure 311, reduces the first limiting space, and tightens the steel coil 5 to prevent loosening or displacement; the loading mechanism 2 and the limiting mechanism 3 work cooperatively under the driving of the driving mechanism 4, the loading mechanism 2 continuously rotates to unwind the steel coil 5, and the limiting mechanism 3 continuously adjusts the position to tighten the steel coil 5, thereby ensuring the stability and stability of the unwinding process.
[0036] In some embodiments, the first direction is a vertical direction, and the first limiting piece 32 is horizontally arranged and connected to the top end of the connecting piece 31 in the vertical direction. It can be understood that by setting the moving direction of the limiting mechanism 3 as the vertical direction, the movement of the first limiting piece 32 in the vertical direction can effectively tighten the steel coil 5, so that the movement of the first limiting piece 32 in the vertical direction is more stable and reliable. The first limiting piece 32 is horizontally arranged, which can better adapt to the circular cross section of the steel coil 5, and ensure uniform tightening of the steel coil 5 in the radial direction, avoiding loosening or uneven tightening of the steel coil 5 due to the inclination or improper position of the first limiting piece 32.

It can be understood that by arranging the spring 34 and the abutting block 35 on the side of the first limiting piece 32 close to the main shaft 21, the shape and size changes of the steel coil 5 can be better adapted to, the contact between the first limiting piece 32 and the steel coil 5 is more uniform and stable, and the precision and reliability of the limiting are improved. The setting of the spring 34 can buffer the impact force between the first limiting piece 32 and the steel coil 5, reduce the wear caused by frequent contact and friction, and prolong the service life of the first limiting piece 32 and the steel coil 5.
[0038] In some embodiments, the end of the first limiting piece 32 away from the connecting piece 31 is connected with a second limiting piece 33, the second limiting piece 33 is arranged in the vertical direction, and the second limiting piece 33 and the main shaft 21 form a second limiting space for clamping in the axial direction of the steel coil 5. It can be understood that this embodiment further increases the second limiting piece 33 on the basis of the first limiting piece 32 to form a second limiting space for clamping in the axial direction of the steel coil 5, preventing the steel coil 5 from moving axially during unwinding, so that the limiting mechanism 3 can not only limit the steel coil 5 in the radial direction, but also in the axial direction, further improving the stability of the steel coil 5.
[0039] In some embodiments, the first limiting piece 32 is provided with a first adjusting slot 321 along the axis direction of the main shaft 21, the second limiting piece 33 is provided with a first threaded hole 331, and the first limiting piece 32 is connected with the second limiting piece 33 through a first bolt, which passes through the first adjusting slot 321 and is threadedly connected with the first threaded hole 331.

[0041] In a feasible implementation, the steel coil 5 is first loaded onto the main shaft 21 to ensure that the position of the steel coil 5 is correct and stable; then, according to the size of the steel coil 5 and uncoiling requirements, the second limiting piece 33 is moved along the first adjusting slot 321 by loosening the first bolt to adjust the size of the second limiting space, to ensure that the second limiting piece 33 can effectively axially limit the steel coil 5; then, the driving mechanism 4 starts to output power, the main shaft 21 is driven to rotate by the transmission gear 22, the steel coil 5 wound on the main shaft 21 is gradually unwound, and at the same time, the transmission gear 22 is driven to rotate by the driving mechanism 4, the connecting piece 31 and the first limiting piece 32 are driven to move along the vertical direction by the tooth-shaped structure 311, to reduce the first limiting space and radially limit the steel coil 5. The loading mechanism 2 and the limiting mechanism 3 work cooperatively under the driving of the driving mechanism 4, the loading mechanism 2 continuously rotates to unwind the steel coil 5, and the limiting mechanism 3 continuously adjusts the position to radially and axially limit the steel coil 5, to ensure the stability and stability of the uncoiling process.
[0042] In some embodiments, the connecting piece 31 is provided with a second adjusting slot 312 along the vertical direction, the first limiting piece 32 is provided with a second threaded hole 322, and the connecting piece 31 is connected with the first limiting piece 32 through a second bolt, which passes through the second adjusting slot 312 and is threadedly connected with the second threaded hole 322.
[0043] It can be understood that by arranging the second adjusting groove 312 on the connecting piece 31 and connecting the connecting piece 31 with the first limiting piece 32 through the second bolt, the first limiting piece 32 is adjustable in the vertical direction, which allows the position of the first limiting piece 32 to be flexibly adjusted according to different sizes of the steel coil 5 and uncoiling requirements, and ensures accurate pressing and stable support of the steel coil 5. Through the second bolt connection, the installation and disassembly of the connecting piece 31 and the first limiting piece 32 are more convenient, the difficulty of maintenance and replacement is reduced, and the reliability and service life of the equipment are improved.
