Description

Technical Field

[0001] The utility model relates to the technical field of copper coil unwinding, in particular to a coil unwinding device for copper coil production. Background Art

[0002] Copper coil is a metal component, with product specifications of 0.1~3×50~250mm in various states, mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, connectors, and mainly used as conductive, heat-conductive, and corrosion-resistant equipment, such as electrical components, switches, washers, gaskets, vacuum devices, radiators, conductive base materials, and various parts such as automobile water tanks, heat sinks, and cylinder plates.

[0003] However, in the prior art, the traditional unwinding method is to directly put the copper coil on the rotating shaft of the unwinding device, and unwind the copper coil by rotating it on the rotating shaft. During the unwinding process, the copper strip may gradually loosen, and the strip often scatters, collapses, and has disordered layers, and even jams the subsequent continuous production units. In addition, during the unwinding process of the steel strip, the unwinding amount is difficult to control. When the copper coil rotates on the rotating shaft, it may reverse on the rotating shaft due to operational errors, causing pulling on the copper strip, affecting the internal tension of the copper strip, and even causing damage to the copper strip, resulting in unnecessary economic losses and affecting the winding progress. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the utility model to solve the technical problems is: a coil unwinding device for copper coil production, comprising a base, the outer surface of the base is fixedly connected to a bracket, the outer surface of the bracket is fixedly connected to a motor, the inner surface of the bracket is rotatably connected to a screw, the outer surface of the screw is threadedly connected to a movable ring, the outer surface of the bracket is rotatably connected to a rotating drum, the outer surface of the rotating drum is slidably connected to a connecting ring, the outer surface of the rotating drum is fixedly connected to a limiting rod, the outer surface of the base is fixedly connected to a telescopic rod, and the end of the telescopic rod away from the base is fixedly connected to a slider.

[0005] Preferably, the output end of the motor is fixedly connected to the outer surface of the screw, the outer surface of the screw is threadedly connected to the inner surface of the moving ring, and the outer surface of the moving ring is fixedly connected to the outer surface of the connecting ring. The outer surface of the connecting ring is rotatably connected to a pull rod, the inner surface of the limit rod is slidably connected to a support block, the outer surface of the support block is rotatably connected to the inner surface of the pull rod, and the outer surface of the support block is provided with a copper coil. The screw is rotated, so that the threaded moving ring drives the fixedly connected connecting ring to slide on the outer surface of the rotating drum, and when the connecting ring moves, the pull rod pushes the support block to slide upward in the limit rod until it contacts the inner surface of the copper coil, and the copper coil is quickly fixed on the device.

[0006] Preferably, the outer surface of the screw is fixedly connected to a first ratchet, the outer surface of the drum is rotatably connected to a first clamping block, the outer surface of the first clamping block is fixedly connected to a torsion spring, one end of the torsion spring away from the first clamping block is fixedly connected to the outer surface of the drum, and the outer surface of the first clamping block meshes with the outer surface of the first ratchet. Under the action of the torsion spring, the first clamping block is clamped on the first ratchet, and when the screw rotates, the first clamping block is clamped on the first ratchet, so that the drum can rotate on the bracket, thereby driving the fixed copper coil to rotate and unwind.

[0007] Preferably, the outer surface of the slider is slidably connected to the inner surface of the bracket, the outer surface of the slider is rotatably connected to a rotating rod, the outer surface of the rotating rod is fixedly connected to a second ratchet, and the outer surface of the slider is rotatably connected to a second clamping block. The outer surface of the rotating rod is slidably connected to the outer surface of the copper coil, and the outer surface of the second clamping block is meshed with the outer surface of the second ratchet. The telescopic rod pushes the rotating rod to always contact the copper coil to prevent it from becoming loose, and the second clamping block will be stuck in the second ratchet so that the rotating rod cannot be reversed. The rotating rod is attached to the outer surface of the copper coil, so that the copper coil cannot be reversed, and the copper strip is prevented from being pulled.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. The utility model moves the first clamping block so that it no longer meshes with the first ratchet wheel. At this time, the rotating drum stops rotating, and the motor drives the screw rod to rotate, so that the moving ring drives the fixedly connected connecting ring to slide on the outer surface of the rotating drum. When the connecting ring moves, the supporting block is pushed by the pull rod to slide upward in the limit rod until it contacts the inner surface of the copper coil, and the copper coil is quickly fixed on the device, so that copper coils with different inner diameters can be quickly fixed, preventing shaking when unwinding, which may cause the copper coil to fall off.

[0010] 2. The utility model uses the telescopic rod to push the slider to slide upward on the inner surface of the bracket, so that the rotating rod presses against the outer surface of the copper coil. As the unwinding proceeds, the telescopic rod pushes the rotating rod to always contact the copper coil to prevent looseness. The second clamping block is engaged with the second ratchet to prevent the rotating rod from reversing. The telescopic rod pushes the rotating rod to fit on the outer surface of the copper coil, so that the copper coil cannot be reversed, preventing the copper strip from being pulled.

[0018] Example:

[0019] See also Figure 1 - Figure 5 The utility model provides a technical solution: a coil unwinding device for copper coil production, including a base 1, a bracket 2 is fixedly connected to the outer surface of the base 1, a motor 3 is fixedly connected to the outer surface of the bracket 2, a screw 12 is rotatably connected to the inner surface of the bracket 2, a movable ring 13 is threadedly connected to the outer surface of the screw 12, a rotating drum 5 is rotatably connected to the outer surface of the rotating drum 5, a connecting ring 16 is slidably connected to the outer surface of the rotating drum 5, a limiting rod 6 is fixedly connected to the outer surface of the base 1, a telescopic rod 7 is fixedly connected to the outer surface of the base 1, and a slider 8 is fixedly connected to the end of the telescopic rod 7 away from the base 1.

[0020] The output end of the motor 3 is fixedly connected to the outer surface of the screw 12, the outer surface of the screw 12 is threadedly connected to the inner surface of the moving ring 13, and the outer surface of the moving ring 13 is fixedly connected to the outer surface of the connecting ring 16. The outer surface of the connecting ring 16 is rotatably connected to the pull rod 14, and the inner surface of the limit rod 6 is slidably connected to the support block 15, the outer surface of the support block 15 is rotatably connected to the inner surface of the pull rod 14, and the outer surface of the support block 15 is provided with a copper coil 4. The screw 12 rotates, and the moving ring 13 drives the fixedly connected connecting ring 16 to slide on the outer surface of the rotating drum 5 through the threaded connection between the moving ring 13 and the screw 12. When the connecting ring 16 moves, the pull rod 14 pushes the support block 15 to slide upward on the inner surface of the limit rod 6 until it contacts the inner surface of the copper coil 4, and the copper coil 4 is quickly fixed.

[0021] The outer surface of the screw 12 is fixedly connected with a first ratchet 17, and the outer surface of the drum 5 is rotatably connected with a first clamping block 18. The outer surface of the first clamping block 18 is fixedly connected with a torsion spring 19. One end of the torsion spring 19 away from the first clamping block 18 is fixedly connected to the outer surface of the drum 5, and the outer surface of the first clamping block 18 is meshed with the outer surface of the first ratchet 17. The torsion spring 19 pulls the fixedly connected first clamping block 18 to rotate, so that it is clamped on the first ratchet 17. When the screw 12 rotates, the first clamping block 18 is clamped on the first ratchet 17, so that the drum 5 can rotate on the outer surface of the bracket 2, thereby driving the fixed copper coil 4 to rotate and unwind.

[0022] The outer surface of the slider 8 is slidably connected to the inner surface of the bracket 2, the outer surface of the slider 8 is rotatably connected to the rotating rod 9, the outer surface of the rotating rod 9 is fixedly connected to the second ratchet 11, and the outer surface of the slider 8 is rotatably connected to the second clamping block 10. The outer surface of the rotating rod 9 is slidably connected to the outer surface of the copper coil 4, and the outer surface of the second clamping block 10 is meshed with the outer surface of the second ratchet 11. The telescopic rod 7 on the base 1 pushes the slider 8 to slide upward on the inner surface of the bracket 2, so that the outer surface of the rotating rod 9 is against the outer surface of the copper coil 4 to prevent looseness. When the rotating rod 9 does not rotate, the second clamping block 10 will be stuck in the second ratchet 11, so that the rotating rod 9 cannot be reversed, and thus the copper coil 4 cannot be reversed.

[0023] Working principle:

[0024] When in use, the copper coil 4 to be unwound is moved to the outside of the rotating drum 5. At this time, the first clamping block 18 on the rotating drum 5 is moved so that it is no longer meshed with the first ratchet 17. At this time, the motor 3 is started to drive the screw 12 to rotate. The threaded connection between the moving ring 13 and the screw 12 is made so that the moving ring 13 drives the fixedly connected connecting ring 16 to slide on the outer surface of the rotating drum 5. When the connecting ring 16 moves, the support block 15 is pushed by the pull rod 14 to slide upward in the limit rod 6 until it contacts the inner surface of the copper coil 4, and the copper coil 4 is quickly fixed on the device. At this time, the first clamping block 18 is released. Under the action of the torsion spring 19, the first clamping block 18 is clamped on the first ratchet 17. When the screw 12 rotates, the first clamping block 1 8 is stuck on the first ratchet 17, so that the rotating drum 5 can rotate on the bracket 2, thereby driving the fixed copper coil 4 to rotate and unwind. During the unwinding process, the telescopic rod 7 on the base 1 pushes the slider 8 to slide upward on the inner surface of the bracket 2, so that the rotating rod 9 presses against the outer surface of the copper coil 4, and as the copper coil 4 rotates, the rotating rod 9 rotates on the slider 8, and the second clamping block 10 slides on the outer surface of the second ratchet 11, and presses against the copper coil 4 through the rotating rod 9 to prevent looseness. When the unwinding stops, the second clamping block 10 will be stuck on the second ratchet 11, so that the rotating rod 9 cannot be reversed, and the rotating rod 9 is pushed to fit on the outer surface of the copper coil 4 through the telescopic rod 7, so that the copper coil 4 cannot be reversed.
