[0036] See also Figure 5-Figure 7 The centering mechanism 9 includes a second moving block 901 arranged on the side wall of each first moving plate 12, and each second moving block 901 is connected to the side wall of the first moving plate 12 through a fifth reset mechanism 10, and the side wall of each second moving block 901 is fixedly connected with a second push plate 902 arranged obliquely, and a plurality of balls 903 are arranged on the top of the filter plate 103, and the motor 702 is started, and the rotation of the motor 702 drives the rotation of the cam 703. When the tip of the cam 703 abuts against the side wall of the first moving plate 12, the first moving plate 12 is pushed to move in the direction away from the fixed plate 701. At the same time, the first spring 204 is stretched, and when the first moving plate 12 moves, the second moving block 901 and the second push plate 902 are driven to move synchronously through the fifth reset mechanism 10. When the second push plate 902 abuts against the side wall of the clamp 1101, the dry-type transformer body 11 can be pushed to move on the ball 903, so that the dry-type transformer body 11 can be centered.

[0037] See also Figure 7 The fifth resetting mechanism 10 includes a fourth sleeve 1001 fixedly connected to the side wall of each second moving block 901, and each fourth sleeve 1001 is inserted with a fourth rod 1002, the other end of the fourth rod 1002 is fixed to the side wall of the first moving plate 12, and the side wall of each fourth sleeve 1001 is sleeved with a fifth spring 1003. After the dry-type transformer body 11 is centered, when the first moving plate 12 continues to move, the fifth spring 1003 is gradually compressed.

[0038] Working principle: during use, when the vacuum varnishing tank 1 needs to be varnished, first open the tank cover 102, then hoist the dry-type transformer body 11 into the tank body 101 and place it on the filter plate 103, then close the tank cover 102, and then perform the vacuum operation. At the same time, start the motor 702, and the rotation of the motor 702 drives the rotation of the cam 703. When the tip of the cam 703 abuts against the side wall of the first movable plate 12, the first movable plate 12 is pushed to move away from the fixed plate 701. At the same time, the first spring 204 is stretched, and when the first movable plate 12 moves, the second movable block 901 and the second push plate 902 are driven to move synchronously through the fifth reset mechanism 10. When the second push plate 902 abuts against the side wall of the clamp 1101, the dry-type transformer body 11 can be pushed to move on the ball 903, so that the dry-type transformer body 11 can be adjusted in the center.

[0039] When the tip of the cam 703 passes over the side wall of the first moving plate 12, the first moving plate 12 can be moved and reset under the action of the first spring 204, and the first moving plate 12 can be reciprocated in this way, and when the first moving plate 12 moves in the direction close to the winding 1102, when the extrusion plate 15 abuts against the surface of the winding 1102, the fourth spring 604 is gradually compressed. After the U-shaped frame 18 abuts against the side wall of the clamp 1101, when the first moving plate 12 continues to move, the second spring 303 is compressed, and at the same time, the first push plate 501 is moved in the direction close to the second moving plate 14, and the two second moving plates 14 are moved away from each other along the inclined surface 502. At the same time, the two extrusion plates 15 are driven to move away from each other through the fourth reset mechanism 6, and the third spring 402 is compressed. Under the action of the fourth spring 604, the two extrusion plates 15 can slide along the surface of the winding 1102 and form an extrusion effect.

[0040] When the first movable plate 12 is reset by moving away from the dry-type transformer body 11, the second movable plate 14 is gradually separated from the inclined surface 502. At this time, the two second movable plates 14 can move closer to each other under the action of the third spring 402, and the two extrusion plates 15 can slide along the surface of the winding 1102 and move closer to each other under the action of the fourth reset mechanism 6, and can form an extrusion effect, so as to facilitate the discharge of the air remaining in the gap of the winding 1102, ensure the efficiency and effect of vacuuming, and thus improve the efficiency and effect of varnishing;

[0041] After the vacuuming is completed, the paint liquid is supplied into the tank body 101, and the winding 1102 is immersed in the paint liquid. At this time, the squeezing plate 15 can also slide along the surface of the winding 1102, and the second movable plate 14 and the squeezing plate 15 can have a stirring effect when they move, so as to improve the efficiency and effect of the paint liquid. At the same time, the squeezing operation can also make the paint liquid more evenly distributed on the surface of the winding 1102, and it is also convenient to discharge the residual air, so as to ensure the efficiency and quality of the paint dipping. After the paint dipping is completed, the squeezing plate 15 slides on the surface of the winding 1102 to remove excess paint liquid, so as to ensure the quality of the paint dipping and avoid the waste of the paint liquid.

[0042] Furthermore, when the two extrusion plates 15 move away from or towards each other, the push rod 801 is driven to move synchronously. When the push rod 801 abuts against the side wall of the triangular block 803, the extrusion plate 15 is pushed to move in the direction away from the winding 1102. At the same time, the third sleeve 602 slides into the third sleeve 601, and the fourth spring 604 is compressed. When the push rod 801 passes over the triangular block 803, the extrusion plate 15 can move in the direction close to the winding 1102 under the action of the fourth spring 604. This reciprocating process can make the extrusion plate 15 have a slapping effect on the winding 1102. When vacuuming, it is convenient to discharge the air remaining in the gap of the winding 1102. When dipping in paint, it can improve the efficiency and quality of dipping in paint. After the dipping in paint is completed, it is convenient to remove excess paint liquid on the surface of the winding 1102, thereby ensuring the quality of dipping in paint and avoiding waste of paint liquid.

[0043] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
