[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] This embodiment provides a coil unwinding device for cutting core coils, such as Figure 1-Figure 3 As shown, the unwinding device for cutting the core coil includes a support platform 1.

[0027] A tensioning head 2 for fixing the core roll is rotatably provided at the front end of the support platform 1, a driving mechanism 3 for driving the tensioning head 2 to rotate is provided on the support platform 1, an auxiliary mechanism 4 for clamping the side of the core roll is provided on the side of the tensioning head 2 corresponding to the front end of the support platform 1, and a correction mechanism 5 for driving the support platform 1 to rotate is provided at the bottom of the support platform 1.

[0028] The auxiliary mechanism 4 includes a fixed rod 41 fixedly connected to the front end of the support platform 1, a roller frame 42 hinged on the side of the fixed rod 41 close to the tensioning head 2, a pressure roller 44 rotatably installed at the front end of the roller frame 42, and a second electric telescopic rod 43 whose two ends are respectively hinged to the fixed rod 41 and the roller frame 42 for driving the roller frame 42 to move closer to or away from the tensioning head 2. A photoelectric sensor 45 for monitoring the unwinding path of the iron core roll is fixedly installed on the side of the front end of the roller frame 42, and the photoelectric sensor 45 is connected to the correction mechanism 5.

[0029] During use, the core roll is fixed on the tensioning head 2, and the tensioning head 2 is driven by the driving mechanism 3 to rotate and unwind. The roller frame 42 of the auxiliary mechanism 4 uses the second electric telescopic rod 43 to make the pressure roller 44 gently press on the side of the core roll, thereby assisting unwinding and maintaining the stability of the unwinding path; then the driving mechanism 3 is started, driving the tensioning head 2 to rotate, and the core roll begins to unwind. The pressure roller 44 gradually descends as the diameter of the core roll decreases, maintaining contact with the side of the core roll; the photoelectric sensor 45 continuously monitors the unwinding path of the core roll. If there is a slight deviation in the path, the photoelectric sensor 45 will immediately capture this change; when the photoelectric sensor 45 detects a deviation, it will send a signal to the correction mechanism 5. After receiving the signal, the correction mechanism 5 will drive the support table 1 to make a slight rotation adjustment, thereby correcting the unwinding path of the core roll. After precise unwinding and correction, the core roll can be sent to the subsequent cutting equipment for cutting.

[0030] Specifically, the tensioning head 2 includes a limit plate 21 rotatably mounted at the front end of the support platform 1, a center column 22 fixedly connected to the center of the limit plate 21, a drive sleeve 23 sleeved on the end of the center column 22 away from the limit plate 21 and moving laterally, a first electric telescopic rod 24 embedded in the end of the center column 22 away from the limit plate 21 and the movable end connected to the drive sleeve 23 through a lock nut 241, and four groups of expansion arms 25 distributed in a ring array on the side of the drive sleeve 23 through a pair of hinge rods 26. The expansion arms 25 are all slidably connected to the limit plate 21. A pressure sensor is provided inside the expansion arm 25, and the output end of the pressure sensor is connected to the input end of the first electric telescopic rod 24. The pressure roller 44 has a A pressure sensor with an output end connected to the input end of the second electric telescopic rod 43; initially, the expansion arm 25 is in a retracted state, and the core coil can be easily put on the central column 22. The first electric telescopic rod 24 is started, and its movable end pushes the driving sleeve 23 to move on the central column 22. At the same time, the driving sleeve 23 drives the expansion arm 25 to expand outward through the hinge rod 26, tightly hugging the core coil to achieve a tightening effect; the pressure sensor inside the expansion arm 25 monitors the clamping force in real time and feeds back the signal to the first electric telescopic rod 24 to ensure that the tightening force is moderate and will not damage the core coil; when the core coil is gradually unwound and the diameter decreases, the expansion arm 25 will shrink inward accordingly, but always maintain a certain tightening force.

[0031] Specifically, the driving mechanism 3 includes a rotating shaft 31 fixedly connected to the center of the limit plate 21 and rotatably mounted on the top of the support platform 1 through a bearing seat, a reduction gear 32 fixedly mounted on the top of the support platform 1 and connected to the rotating shaft 31 at the output end, a connecting shaft 33 rotatably mounted on the top of the support platform 1 through a bearing seat and connected to the input end of the reduction gear 32, a driven wheel 34 fixedly connected to the rear end of the connecting shaft 33, a driving wheel 35 rotatably mounted on the rear end of the support platform 1 and connected to the driven wheel 34 through a transmission belt 36, and a rotating motor 37 fixedly mounted on the top of the support platform 1 and connected to the driving wheel 35 at the output shaft; the rotating motor 37 is started to drive the driving wheel 35 to rotate, and the driving wheel 35 transmits power to the driven wheel 34 through the transmission belt 36, thereby driving the connecting shaft 33 and the reduction gear 32 to rotate, and the output end of the reduction gear 32 drives the limit plate 21 and the center column 22 to rotate through the rotating shaft 31, thereby realizing the unwinding of the core roll.

[0032] Specifically, the correction mechanism 5 includes a fixed base 51 fixedly mounted on the ground, a toothed disc 52 rotatably connected to the top of the fixed base 51 and fixedly connected to the bottom surface of the support platform 1, a driving gear 53 engaged with the side of the toothed disc 52 and rotatably connected to the side of the fixed base 51 through a bracket 511, and a correction motor 54 fixedly mounted on the bottom of the bracket 511 and with an output shaft connected to the driving gear 53, wherein the input end of the correction motor 54 is connected to the output end of the photoelectric sensor 45; during the unwinding process, the photoelectric sensor 45 continuously monitors the unwinding path of the core roll. Once a path deviation is detected, the photoelectric sensor 45 sends a signal to the correction motor 54, and the correction motor 54 starts, driving the driving gear 53 to rotate, and the driving gear 53 engages with the toothed disc 52, driving the support platform 1 as a whole to make a slight rotation adjustment, thereby correcting the unwinding path of the core roll.

[0033] It should be noted that the bottom edge of the fixed base 51 has a flange edge 512; when fixing the mounting base, bolts are used to pass through the flange edge 512 to complete ground fixation.

[0034] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
