A second through hole 107 is provided, and the first through hole 106 and the second through hole 107 are arranged opposite to each other; the rotating component 2 is arranged at one end of the turret 1 through the first through hole 106, and can drive the turret 1 to rotate; the unwinding component 3 includes a first slide 301 and a second slide 302 for placing the roll, the first slide 301 and the second slide 302 are arranged opposite to each other on the same side of the turret 1, and the two ends of the first slide 301 and the second slide 302 are respectively connected to the first square passage 101 and the second square passage 102.

[0028] Among them, a bracket is also provided, and the turret 1 is arranged on the bracket to facilitate its rotation. In some embodiments, the support block 103 is a reinforcing rib, the first square tube 101 and the second square tube 102 are equal in length and parallel to each other, two reinforcing ribs are vertically arranged between the first square tube 101 and the second square tube 102, and the first plate body 104 and the second plate body 105 are connected to the two ends of the first square tube 101 and the second square tube 102, respectively, and the periphery of the turret 1 is arranged into a rectangular parallelepiped structure, and the first plate body 104 and the second plate body 105 are preferably steel plates. The slewing assembly 2 can drive the turret 1 to rotate, and the slewing assembly 2 is preferably a drive motor. During use, the reel is first placed on the first slide 301 and the second slide 302, and the drive motor is turned on to reel in and unreel the coil.

[0029] The design of the turret 1 eliminates the intermediate shaft core with high precision requirements, and utilizes the concentricity of the first through hole 106 and the second through hole 107 at both ends to ensure the normal operation of the turret 1. Two square tubes are used as the main body, and reinforcing ribs are added in the middle of the square tubes, which can increase the rigidity of the turret 1 while reducing processing requirements and costs.

[0030] In one embodiment, the unwinding assembly 3 further includes a moving module 310, which is disposed on one side of the first slide 301. The moving module 310 includes a first movable end 311, and the first slide 301 is connected to the first movable end 311, and can slide along the length direction of the turret 1 through the first movable end 311. The first slide 301 is connected to the first movable end 311, and the distance between the first slide 301 and the second slide 302 is changed by changing the position of the first slide 301, thereby meeting the requirement of winding up coils of various specifications.

[0031] Furthermore, the unwinding assembly 3 further includes a limit plate 303, the two ends of which are respectively arranged on the same side of the first square tube 101 and the second square tube 102, and a clamping area is arranged on the limit plate 303, through which the limit plate 303 is clamped with the end of the current collector roll. There are two pairs of limit plates 303, the two ends of which are respectively connected to the first square tube 101 and the second square tube 102, to limit the rolls on both sides, and the clamping area on the limit plate 303 is adapted to the two ends of the roll, and when the roll rotates, the rotation center of the roll is limited to a relative position, so that the rotation process is stable and not prone to shaking.

[0032] In some embodiments, the moving module 310 is disposed on one side of the second slide 302, and the second slide 302 is connected to the first movable end 311 of the moving module 310, and can slide along the length direction of the turret 1 through the first movable end 311. The first slide 301 and the second slide 302 are both connected with moving components, which can enhance their flexibility, make the adjustment process more convenient and quick, and also facilitate the positioning of the material roll.

[0033] Furthermore, the unwinding assembly 3 also includes a slide drive, and the driving end of the slide drive is connected to the first slide 301 to drive the first slide 301 to move along the length direction of the turret 1. The slide drive selects a driving cylinder, and the first slide 301 can be driven to and fro along the length direction of the turret 1 by the extension and contraction of the driving cylinder, thereby improving the automation of the equipment and making the operation more convenient and quick. It is understandable that the slide drive can also drive the first slide 301 in other ways, not limited to the driving cylinder, and this application does not make specific limitations.

[0034] In some embodiments, the moving module 310 further includes a second movable end 312, which is disposed on a side of the first movable end 311 facing the current collector roll, and the limiting plate 303 is connected to the second movable end 312, and can be moved along the length direction of the turret 1 through the second movable end 312. The limiting plate 303 can be moved through the second movable end, which increases its flexibility and can limit rolls of different specifications. The limiting plate 303 and the first slide 301 are placed on the same moving module 310, which ensures the repeated positioning accuracy of the slide assembly during the reciprocating movement, and ensures that the first unwinding portion is stably inserted into the current collector roll core.

[0035] Furthermore, the mobile module 310 further includes a guide member 313, which is arranged on the turret 1 along the length direction of the current collector roll, the guide member 313 is a slide rail, and the first movable end 311 is a slider. In some embodiments, the second movable end 312 is also a slider, and the first slide 301 and the second slide 302 are connected to the slider, and move along the length direction of the turret 1 through the slide rail. It is understandable that the mobile module 310 can also be replaced by other means, such as a screw guide rail, a gear rack, etc., which is not specifically limited in this application.

[0036] During use, first adjust the relative position between the first slide 301 and the second slide 302, place the roll between the first unwinding part and the second unwinding part, and clamp the limit plate 303 at both ends of the roll. At this time, rolls are placed on both sides of the turret 1. When in use, only the roll on the first side of the turret is wound or unwound. When the roll needs to be changed, the rotating component 2 drives the turret 1 to rotate and replaces the roll on the second side to the specified position. At the same time, the roll on the first side is put down, replaced with a new roll, and waits for the second roll change.

[0037] Example 2

[0038] This embodiment is similar to embodiment 1. Figure 3As shown, the difference is that it also includes a first locking mechanism 4 for fixing the limit plate 303. The first locking mechanism 4 is mainly used to fix the limit plate 303, so that it has a better limit effect on both ends of the reel. In some embodiments, the first locking mechanism 4 includes a locking screw, a first nut 402 and a second nut 403, one end of the locking screw is fixedly set on the turret 1, the first nut 402 is sleeved on the locking screw, the limit plate 303 passes through the locking screw, and one side of the limit plate 303 abuts against the first nut 402, and the second nut 403 is sleeved on the locking screw and abuts against the other side of the limit plate 303. The limiting plate 303 is mainly clamped and fixed by the first nut 402 and the second nut 403. A through hole is provided in the middle of the limiting plate 303. The diameter of the through hole is slightly larger than the diameter of the locking screw to ensure that it passes through the locking screw. The first nut 402 is first sleeved on the locking screw, and then the limiting plate 303 is passed through the locking screw. Finally, the second nut 403 is sleeved into the locking screw, and the two nuts clamp the limiting plate 303. When the relative position of the limiting plate 303 needs to be adjusted, taking the adjustment to the edge as an example, the first nut 402 is first rotated to a specific position, and then the limiting plate 303 moves through the second movable end 312, and the second nut 403 is rotated to clamp the limiting plate 303 to complete the movement.

[0039] In this embodiment, the position of the limit plate 303 is adjusted by utilizing the position of the first nut 402 and the second nut 403. The two ends of the limit plate 303 are connected to the guide rails on the turret 1, so that the limit plate 303 can be suitable for rolls of different widths. At the same time, by rotating the first nut 402 to control the moving distance, the adjustment process can also be made more precise, so that the clamping area on the limit plate 303 can be accurately clamped with the two ends of the roll.

[0040] Example 3

[0041] This embodiment is similar to embodiment 1. Figure 4 As shown, the difference is that a second locking mechanism 5 is provided at the second end of the turret 1. The second locking mechanism 5 is mainly used to lock the turret 1, improve the safety of the current collector roll automatic switching device, prevent the turret 1 from rotating incorrectly due to the failure of the rotary motor, and eventually cause the pole piece to break and other wire release, so as to ensure the normal operation of the equipment.

[0042] Further, the second locking mechanism 5 includes a driving assembly 501 and a locking member 502. The driving end of the driving assembly 501 is connected to the first end of the locking member 502. The driving assembly 501 drives the first end of the locking member 502 to move so that the second end of the locking member 502 is inserted into the second through hole 107. The driving assembly 501 is a driving cylinder, and the locking member 502 is a latch. The locking groove is adapted to the latch. The driving end of the driving cylinder is connected to one end of the latch. When the driving cylinder is extended, the latch can be pushed into the locking groove of the turret 1 to lock the turret 1 to prevent it from rotating and improve the safety of the equipment. When the turret 1 needs to rotate, the driving cylinder is retracted to remove the latch. At this time, the turret 1 can rotate normally.

[0043] During use, when it is necessary to change the roll, the driving cylinder contracts and pushes out the pin, the rotary assembly 2 drives the turret 1 to rotate, and the new roll on the other side of the turret 1 is rotated to the specified position, and the driving cylinder of the second tightening device extends to push the pin into the second through hole 107 to complete the roll change.
