Technical Field

[0001] This utility model relates to the technical field of transformer core production equipment, specifically a 180-degree online transformer core flipping machine. Background Technology

[0002] The transformer core is one of the main components of a transformer. It is made of magnetic materials and is mainly used to transmit magnetic flux. It is the core of the transformer's magnetic circuit and is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content. The surface is coated with insulating varnish to reduce eddy current losses and prevent the core from overheating.

[0003] Currently, transformer cores need to be flipped 180 degrees during production and transportation. However, existing 180-degree flipping machines for transformer cores are usually standalone devices that require workers to move to the flipping equipment to perform the flipping operation. The entire operation process is time-consuming and cumbersome, and therefore cannot meet the needs of flipping large quantities of transformer cores. To address this, we propose an online 180-degree flipping machine for transformer cores. Utility Model Content

A drive sprocket is fixedly connected to the output end of the flipping motor. A drive sprocket is fixedly installed at the rear end of the top of the base. The base is equipped with an auxiliary wheel assembly, and a chain is fitted around the outer side of the auxiliary wheel assembly and the drive sprocket. A feeding conveyor and a discharging conveyor are respectively provided on the left and right sides of the base. An electrical control box is fixedly installed on the left end of the front of the feeding conveyor. An upper conveyor is fixedly installed on the top of the inner side of the tilting seat. A support plate is fixedly connected to the lower end of the inner cavity of the tilting seat. Lifting cylinders are fixedly installed at both the front and rear ends of the bottom of the support plate. A lower conveyor is fixedly connected to the extended end of the lifting cylinder. A fixing plate is fixedly installed on the upper rear side of the inside of the tilting seat. A side guard cylinder is fixedly installed at the middle of the rear side of the fixing plate. A side guard baffle is fixedly installed on the extended end of the side guard cylinder.

[0006] Preferably, the chain is located inside the annular groove, and both ends of the chain are fixedly connected to the two fixing blocks respectively.

[0007] Preferably, the outer side of the base and the flip seat is provided with a protective isolation frame.

[0008] Preferably, a fixing sleeve is fixedly installed at both the front and rear ends of the top of the feeding conveyor seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a first cylinder to extend the first blocking roller, which then blocks the support plate carrying the transformer core. Simultaneously, the first motor on the front of the lower conveyor seat is de-energized. Then, with the assistance of the support plate, the lifting cylinder drives the lower conveyor seat upward. After the conveying roller in the upper conveyor seat contacts the support plate on top of the transformer core, it can clamp and position the transformer core. Next, the side guard cylinder drives the side guard baffle to extend and fit against the rear side of the transformer core. This enables the transformer core to be positioned and supported when the flipping seat rotates clockwise, preventing the transformer core from falling during the flipping process. Then, the flipping motor drives the drive sprocket to rotate. With the assistance of the auxiliary wheel group and the cooperation of the fixed block, the rotating drive sprocket can drive the flipping seat to rotate clockwise via the chain. After the flipping seat has rotated 180 degrees, the flipping motor stops working. This makes the flipping machine capable of fast and safe flipping, and it is convenient to use and easy to operate.

[0014] 2. By setting a fixed sleeve, the present invention can adjust the position of the limiting baffle at the top of the feeding conveyor seat when the rotating block drives the adjusting threaded rod to rotate, thereby enabling the centering and guiding of pallets of different specifications.

[0030] This technical solution: By setting up the feeding conveyor seat 2, the transformer core to be flipped can be transported to the flipping seat 5 via a pallet. A corresponding pallet is also placed on top of the transformer core. After the pallet carries the transformer core to be flipped into the top of the lower conveyor seat 8, the first proximity switch 15 in the mounting slot 16 of the lower conveyor seat 8 is blocked at the right end of the conveying pallet. The first cylinder 18 then drives the first blocking roller 17 to extend, thereby blocking the pallet carrying the transformer core. Simultaneously, the first motor 24 on the front of the lower conveyor seat 8 is de-energized.

The transformer core is positioned and supported, preventing it from falling during the flipping process. Then, the flipping motor 22 drives the drive sprocket 27 to rotate. With the assistance of the auxiliary wheel group 35 and the cooperation of the fixed block 28, the rotating drive sprocket 27 can drive the flipping seat 5 to rotate clockwise via the chain 12. After the flipping seat 5 has rotated 180 degrees, the flipping motor 22 stops working. At this time, the positions of the upper conveyor seat 7 and the lower conveyor seat 8 are reversed. Then, the lifting cylinder 13, the side guard cylinder 20, and the first cylinder 18 drive the lower conveyor seat 8, the side guard baffle 19, and the first blocking roller 17 to reset in sequence. Then, the second motor 23 on the front of the upper conveyor seat 7 rotates. With the assistance of the pulley 25 and the synchronous belt 26, the flipped transformer core and the pallet can continue to be transported to the discharge conveyor seat 3. Thus, this flipping machine has the ability to flip quickly and safely, and is convenient to use and easy to operate.

[0031] It should be noted that the second proximity switch 29 and the second cylinder 30 will operate when the material is fed from the top of the upper conveyor seat 7, and at this time the corresponding flipping seat 5 will perform a counterclockwise flipping operation.
