[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The embodiment of the present application solves the problems in the prior art by providing a transformer coil pay-off frame.

[0027] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0028] Embodiment 1:

[0029] The specific structure of this embodiment is as follows: Figure 1-Figure 3 As shown, a transformer coil pay-off frame comprises:

[0030] A base 11, a left side plate 5 and a right side plate 1 are connected to the top of the base 11, and a second through hole 20 is provided at the middle position of the top of the left side plate 5 and the right side plate 1. A wire-paying shaft 2 is connected inside the second through hole 20, and a plurality of limit holes 4 are horizontally provided inside the wire-paying shaft 2. A pair of discs 3 are sleeved on the outer side of the wire-paying shaft 2;

[0031] A first housing 12 is connected to the middle position above the base 11 . A lifting mechanism is provided inside the first housing 12 . A wire barrel 8 is connected to one side of the lifting mechanism. Both ends of the wire barrel 8 are connected to connecting sleeves 16 .

[0032] In some examples, the lifting mechanism includes a first motor 6 connected to the inner wall of the first shell 12, one end of the output shaft of the first motor 6 is connected to a reciprocating screw 7, one end of the reciprocating screw 7 is connected to a bearing seat 13, the bearing seat 13 is fixedly connected to the first shell 12, the outer side of the reciprocating screw 7 is sleeved with a ball nut pair 10, the outer side of the ball nut pair 10 is fixedly connected with a fixing sleeve 9, one side of the fixing sleeve 9 is fixedly connected to the wire tube 8, and by setting up the lifting mechanism, it is convenient to lift and lower one end of the wire, and then it is convenient to evenly wind the wire around the outer side of the vertically placed magnetic core.

[0033] In some examples, the connecting sleeve 16 is configured to be open, and the outer edge of the connecting sleeve 16 is provided with rounded corners, which is beneficial to prevent the wire from directly contacting the outer edge of the wire barrel 8, thereby reducing wear.

[0034] In some examples, a first through hole 18 is opened at the top of the right side plate 1, and the first through hole 18 is connected to the second through hole 20. A second motor 15 is connected to the outer side of the right side plate 1. One end of the output shaft of the second motor 15 passes through the outer side of the right side plate 1 and is connected to a second gear 19. The outer side of the second gear 19 is meshingly connected to the first gear 14. The inner ring of the first gear 14 is fixedly connected to the pay-off shaft 2. By turning on the second motor 15, the second gear 19 is driven to rotate, and then the first gear 14 and the pay-off shaft 2 are driven to rotate, thereby avoiding the need to manually rotate the pay-off shaft 2 to pay out the line, thereby improving the pay-off efficiency.

[0035] In some examples, the width of the first through hole 18 is greater than the width of the first gear 14 , so that the first gear 14 can be easily inserted into the first through hole 18 .

[0036] When the utility model releases the wire, the wire is passed through the wire tube 8, and the first motor 6 is turned on to drive the reciprocating screw rod 7 to rotate, thereby driving the ball nut pair 10 and the fixing sleeve 9 to rise and fall, so as to facilitate the lifting and lowering of one end of the wire, and then facilitate the wire to be evenly wound around the outside of the vertically placed magnetic core, thus solving the problem that when the magnetic core is placed vertically, it is easy to cause the wire to be difficult to be evenly wound around the magnetic core.

[0037] Embodiment 2:

[0038] The specific structure of this embodiment is as follows: Figure 4As shown, a pair of second shells 17 are correspondingly connected to the back side of the disc 3, and a pair of third through holes 21 are correspondingly opened inside the second shell 17. An insertion rod 25 is connected to the inside of the third through hole 21, and a pull plate 22 is connected to the top of the insertion rod 25. A return spring 24 is sleeved on the outer side of the insertion rod 25, and one end of the return spring 24 is connected to a fixing ring 23, which is fixedly connected to the insertion rod 25, and the other end of the return spring 24 is fixedly connected to the inner wall of the second shell 17. When it is necessary to install the wound wire on the pay-off shaft 2 on the pay-off frame, the pull plates 22 on both sides are pulled outward at the same time to facilitate the upper and lower insertion rods 25 to be taken out from the limiting hole 4, and then the disc 3 is conveniently removed from the pay-off shaft 2.

[0039] In some examples, the diameter of the insertion rod 25 is smaller than the diameter of the limiting hole 4 , which facilitates the insertion of the insertion rod 25 into the limiting hole 4 .

[0040] The utility model simultaneously pulls out the pull plates 22 on both sides, thereby conveniently driving the insertion rods 25 on the upper and lower sides to be taken out from the limiting holes 4, and then conveniently adjusting the position of the disk 3, thereby conveniently limiting the wires of different widths.

[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
