Description

Technical Field

[0001] The present invention relates to the technical field of transformer core assembly, and specifically to an outsourcing tape winding device for transformer core assembly. Background Art

[0002] The transformer core is the main magnetic circuit part in a transformer. It is usually stacked by hot-rolled or cold-rolled silicon steel sheets with a relatively high silicon content and an insulating paint coated on the surface, and forms a complete electromagnetic induction system with the coil wound around it. The core has a high magnetic permeability, which can enable the primary winding of the transformer to generate a large magnetic induction intensity with a small excitation current, so that most magnetic lines of force are constrained within the core, effectively transferring magnetic energy to the secondary, improving the electromagnetic coupling efficiency, reducing magnetic leakage. By reasonably selecting the core material and designing the magnetic circuit, it is possible to avoid the phenomenon of magnetic saturation in the core during operation, ensuring the stable performance of the transformer. When assembling the transformer core, it is necessary to perform winding processing of the outsourcing tape to prevent phenomena such as electric leakage and short circuit between the winding and the core or other components;

[0003] When processing the transformer core, it is necessary to perform multiple turns of winding of the outsourcing tape. However, the released tape is affected by the working environment and has dust particle impurities attached to its surface, which affects the subsequent winding processing effect of the core. Therefore, we propose an outsourcing tape winding device for transformer core assembly. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an outsourcing tape winding device for transformer core assembly, including a processing table. A power cutter is fixedly connected to the top of the processing table. A reel is rotatably connected to the top of the processing table through a rotating bolt. A film roll is sleeved and fixedly connected to the outside of the reel. A dust cleaning device is sleeved and rotatably connected to the outside of the reel through a bearing. A lubricating device is fixedly connected to the side of the dust cleaning device away from the reel. An oil suction device is fixedly connected to the top of the processing table;

[0005] The dust cleaning device includes a fixed collar. By rotating the fixed collar to drive the concave plate to rotate to a position aligned with the tape, it is prevented that after adjusting the tension, the tape has a large bending angle and tight friction contact with the concave plate, which is likely to cause damage. An outer connecting rod is fixedly connected to the outside of the fixed collar. One end of the outer connecting rod away from the fixed collar is fixedly connected to a concave plate. An internal brush is fixedly connected to the inside of the concave plate. By arranging the internal brush inside the concave plate, the surface of the released tape during movement is cleaned of dust, preventing the released tape from being affected by the working environment and having dust particle impurities attached to its surface, which affects the subsequent winding processing effect of the core;

[0006] The fixed collar is sleeved on the reel and rotatably connected to the reel through a bearing. The side of the concave plate away from the outer connecting rod is fixedly connected to one end of the lubricating device;

[0007] A threaded through rod penetrates through and is threadedly connected to the top of the concave plate. Circular torsion blocks are fixedly connected to both the top and the bottom of the threaded through rod. By rotating the threaded through rod to push the circular torsion block at the bottom to press on the processing table, the concave plate with adjusted angle is fixed, preventing the slight rotation of the fixed collar caused by the rotation of the reel during the unwinding of the film, which may lead to ineffective contact between the built-in brush inside the concave plate and the tape. A corrugated ring piece is fixedly connected to the side of the circular torsion block close to the concave plate. By arranging the corrugated ring piece between the docking circular block and the circular torsion block, the threaded through rod is wrapped and protected, preventing dust particles removed from adhering to the surface of the threaded through rod near the built-in brush and affecting the thread fit of the threaded through rod. A docking circular block is fixedly connected to the side of the corrugated ring piece away from the circular torsion block;

[0008] There are two threaded through rods, and the two threaded through rods are distributed on the concave plate. The side of the docking circular block away from the corrugated ring piece is rotatably connected to one side of the concave plate through a bearing.

[0009] Further, the lubrication device includes an arc-shaped connecting rod. One end of the arc-shaped connecting rod is fixedly connected to a square thick plate. A side groove is fixedly connected to the side of the square thick plate away from the arc-shaped connecting rod. A first sponge is fixedly connected to the inner wall of the side groove. The first sponge filled with lubricating oil coats the back of the tape when it contacts the tape, preventing the tape from rubbing against multiple driving rollers multiple times during movement, especially when the tension is relatively high, it is prone to breakage. Oil seepage circular grooves are formed in the inner wall of the side groove. By forming a plurality of oil seepage grooves with smaller apertures in the inner wall of the side groove, a small amount of lubricating oil is discharged when not pushed, preventing a large amount of lubricating oil from continuously discharging from the concave inner groove, resulting in the lubricating oil in the first sponge reaching saturation and overflowing and dripping downward when not in use. An inner concave groove is formed in the inner wall of the oil seepage circular groove. An inner concave plate is slidably connected to the inner wall of the inner concave groove. When the inner concave plate moves upward, the lubricating oil in the area of the inner wall of the inner concave groove close to the oil seepage circular groove is pushed, so that the lubricating oil passes through the oil seepage circular groove and enters the first sponge, preventing the aperture of the oil seepage circular groove from being set too small, resulting in a small amount of lubricating oil overflowing and it being difficult to ensure that the first sponge is always in an oil-soaked state, resulting in poor lubrication effect. Curved inclined holes are formed in the outer surface of the inner concave plate. By forming curved inclined holes in the inner concave plate, it is convenient for the lubricating oil to pass through and be freely distributed in the upper and lower areas of the inner concave plate, preventing a large amount of lubricating oil from being difficult to discharge through the oil seepage circular groove in time when the inner concave plate moves upward, resulting in a large pressure and affecting the use. A top connecting rod is fixedly connected to the top of the inner concave plate. A top connecting block is fixedly connected to the top of the top connecting rod. An electric push rod I is fixedly connected to the bottom of the top connecting block. A bottom fixing block is fixedly connected to the bottom of the electric push rod I. A threaded plug block penetrates and is threadedly connected to the top of the square thick plate. The end of the arc-shaped connecting rod away from the square thick plate is fixedly connected to one side of the inner concave plate. A plurality of oil seepage circular grooves are provided, and the plurality of oil seepage circular grooves are distributed on the inner wall of the side groove. The inner concave plate is arranged as an inner concave plate body with a V-shaped cross-section. The top of the top connecting rod penetrates the inner concave groove and extends to the top of the square thick plate. The top of the bottom fixing block is fixedly connected to the bottom of the square thick plate.

[0010] Further, the oil absorption device includes a vertical support plate. On one side of the vertical support plate, a second electric push rod is fixedly connected. The driving shaft of the second electric push rod penetrates through the vertical support plate and is fixedly connected with a docking square plate. On the top of the docking square plate, a small electric slide rail is fixedly connected. The bottom of the small electric slide rail is slidably connected with a bottom slide plate. The two bottom slide plates move towards each other to compress the second sponge and squeeze out the absorbed lubricating oil into the oil collection shell, preventing the second sponge from being saturated with lubricating oil after long-term use and making it difficult to absorb the lubricating oil on the back of the tape. On one side of the bottom slide plate, a side connecting rod is fixedly connected. The end of the side connecting rod away from the bottom slide plate is fixedly connected with an inner sliding round block. By setting an inner sliding round block at one end of the side connecting rod, the position of the bottom slide plate moving outward is limited, preventing the bottom slide plate from being stretched excessively when moving outward to stretch the second sponge, resulting in poor oil absorption effect of the second sponge and affecting the use. The outer side of the inner sliding round block is sleeved and slidably connected with a circular sleeve. By setting a circular sleeve in the circular through hole opened in the second sponge, the movement of the two bottom slide plates on both sides is limited, preventing the bottom slide plates from squeezing the second sponge excessively, resulting in the gradual damage of the sponge body of the second sponge and making it difficult to use. On the side of the docking square plate close to the bottom slide plate, a second sponge is fixedly connected. When the second sponge contacts the back of the tape, it absorbs and wipes the lubricating oil on its surface, preventing a large amount of lubricating oil from still adhering to the back of the tape that is about to be wound, resulting in difficulty in winding the tape tightly and affecting the winding processing effect of the transformer core. A circular through hole is opened on one side of the second sponge. On one side of the vertical support plate, an oil collection shell penetrates and is slidably connected. T-shaped sliding rods are fixedly connected to both sides of the oil collection shell. The bottom of the vertical support plate is fixedly connected to the top of the processing table. There are two bottom slide plates, and the two bottom slide plates are distributed on both sides of the second sponge. The end of the side connecting rod close to the inner sliding round block penetrates through the circular sleeve and is slidably connected with the circular sleeve. The outer side of the circular sleeve is slidably connected with the inner wall of the circular through hole. One end of the T-shaped sliding rod penetrates through the vertical support plate and is slidably connected with the vertical support plate.

[0011] The present invention provides an outer wrapping tape winding device for assembling a transformer core. It has the following beneficial effects:

[0012] 1. The outer wrapping tape winding equipment for the transformer core assembly sweeps the dust on the surface of the tape that moves after unwinding through an internal brush arranged inside the concave plate, preventing the unwound tape from being affected by the working environment and having dust particle impurities attached to its surface, which may affect the subsequent winding process of the core. The first sponge filled with lubricating oil coats the back of the tape with lubricating oil when it comes into contact with it, preventing the tape from breaking easily when it moves and comes into contact with multiple driving rollers multiple times, especially when in a highly tensioned state. The second sponge absorbs and wipes off the lubricating oil on the surface of the tape when it comes into contact with the back of the tape, preventing a large amount of lubricating oil from still being attached to the back of the tape that is about to be wound, which may make it difficult to tightly wind the tape and affect the winding process of the transformer core.

[0013] 2. The outer wrapping tape winding equipment for the transformer core assembly is equipped with a dust cleaning device. It sweeps the dust on the surface of the tape that moves after unwinding through an internal brush arranged inside the concave plate, preventing the unwound tape from being affected by the working environment and having dust particle impurities attached to its surface, which may affect the subsequent winding process of the core. By rotating the fixed collar to drive the concave plate to rotate and adjust to a position aligned with the tape, it prevents the tape from having a large bending angle and tightly rubbing against the concave plate after adjusting the tension, which may easily cause damage. By rotating the threaded through rod to push the circular torsion block at the bottom to press on the processing table to fix the concave plate after adjusting the angle, it prevents the fixed collar from rotating slightly when the film is unwound and drives the reel to rotate, resulting in the internal brush inside the concave plate being difficult to effectively contact the tape. By setting a corrugated ring between the docking circular block and the circular torsion block to wrap and protect the threaded through rod, it prevents the surface of the threaded through rod near the internal brush from being attached with the cleaned dust particles, which may affect the thread fit of the threaded through rod.

[0014] 3. The outer wrapping tape winding equipment for the transformer core assembly is equipped with a lubrication device. When the concave folding plate moves upward, it squeezes the lubricating oil in the area of the inner wall of the concave inner groove near the oil seepage circular groove, causing the lubricating oil to pass through the oil seepage circular groove and enter the first sponge, preventing the aperture of the oil seepage circular groove from being set too small, resulting in a small amount of lubricating oil overflow and making it difficult to ensure that the first sponge is always in an oil-soaked state, leading to poor lubrication effect. By opening a curved inclined hole on the concave folding plate, it facilitates the lubricating oil to pass through and freely distribute in the upper and lower areas of the concave folding plate, preventing a large amount of lubricating oil from being pushed upward together with the lubricating oil at the top when the concave folding plate moves upward, resulting in a large pressure due to the difficulty of timely discharging a large amount of lubricating oil through the oil seepage circular groove, which may affect the use. The first sponge filled with lubricating oil coats the back of the tape with lubricating oil when it comes into contact with it, preventing the tape from breaking easily when it moves and comes into contact with multiple driving rollers multiple times, especially when in a highly tensioned state. By opening multiple oil seepage grooves with smaller apertures on the inner wall of the side groove, a small amount of lubricating oil is discharged when not being pushed, preventing a large amount of lubricating oil from continuously discharging from the concave inner groove, resulting in the lubricating oil inside the first sponge reaching saturation when not in use and overflowing and dripping downward.

[0015] 4. The outsourcing tape winding equipment for assembling the transformer core is provided with an oil absorption device. When the second sponge contacts the back of the tape, it absorbs and wipes the lubricating oil on its surface, preventing a large amount of lubricating oil from still adhering to the back of the tape to be wound, which may cause the tape to be difficult to wind tightly and affect the winding processing effect of the transformer core. The two bottom-mounted slides move towards each other to compress the second sponge and squeeze out the absorbed lubricating oil inside into the oil collection shell, preventing the second sponge from being saturated with lubricating oil after long-term use and being difficult to absorb the lubricating oil on the back of the tape again. By setting a circular sleeve in the circular through hole opened in the second sponge to limit the movement of the two bottom-mounted slides on both sides, it is prevented that the bottom-mounted slides squeeze the second sponge excessively when compressing it, resulting in the gradual damage of the sponge body of the second sponge and being difficult to use. By setting an inner sliding round block at one end of the side link to limit the position of the bottom-mounted slide moving outward, it is prevented that the bottom-mounted slide stretches the second sponge excessively when moving outward, resulting in poor oil absorption effect of the second sponge and affecting the use.

Detailed implementation manner

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 4 , the present invention provides an outer tape winding device for assembling a transformer core, including a processing table 1, an electric cutter 2 fixedly connected to the top of the processing table 1, a reel 3 rotatably connected to the top of the processing table 1 through a rotating bolt, a film 4 sleeved and fixedly connected to the outside of the reel 3, a dust cleaning device 5 sleeved and rotatably connected to the outside of the reel 3 through a bearing, a lubricating device 6 fixedly connected to one side of the dust cleaning device 5 away from the reel 3, and an oil suction device 7 fixedly connected to the top of the processing table 1;

[0027] The dust cleaning device 5 includes a fixed collar 501, an outer connecting rod 502 fixedly connected to the outside of the fixed collar 501, a concave plate 503 fixedly connected to one end of the outer connecting rod 502 away from the fixed collar 501, and a built-in brush 504 fixedly connected to the inside of the concave plate 503;

[0028] The fixed collar 501 is sleeved on the reel 3 and rotatably connected to the reel 3 through a bearing, and one side of the concave plate 503 away from the outer connecting rod 502 is fixedly connected to one end of the lubricating device 6;

[0029] The top of the concave plate 503 is penetrated and threadedly connected with a threaded through rod 505. Circular torsion blocks 506 are fixedly connected to both the top and bottom of the threaded through rod 505. A corrugated ring 507 is fixedly connected to one side of the circular torsion block 506 close to the concave plate 503. A docking circular block 508 is fixedly connected to one side of the corrugated ring 507 away from the circular torsion block 506.

[0030] There are two threaded through rods 505, and the two threaded through rods 505 are distributed on the concave plate 503. The side of the docking circular block 508 away from the corrugated ring 507 is rotatably connected to one side of the concave plate 503 through a bearing. During use, when the processing table 1 drives the pulling film 4 to wind the transformer core, the reel 3 rotates together. The tape unwound from the film 4 passes through the dust cleaning device 5 during movement and undergoes dust cleaning treatment by the dust cleaning device 5. The non-adhesive side of the back of the tape contacts the lubricating device 6. When the tape moves, the lubricating device 6 lubricates the back of the tape. When the tape passes near the transformer core through the transmission roller, it will contact the oil absorption device 7 and wipe off and absorb the lubricating oil on the back of the tape. After the tape is wound, it can be cut and separated by the electric cutter 2. The tape is unwound from the film 4 outside the reel 3 and then passes through the built-in brush 504 inside the concave plate 503 and then contacts the lubricating device 6. By arranging the built-in brush 504 inside the concave plate 503, the surface of the tape moving after unwinding is cleaned of dust. When adjusting the tension of the tape by changing the position of the transmission roller, the concave plate 503 is rotated by rotating the fixed collar 501 to adjust to a position aligned with the tape. After adjusting the position of the concave plate 503 by rotating the fixed collar 501, the circular torsion block 506 at the top is rotated to drive the threaded through rod 505 to rotate. When the threaded through rod 505 rotates, it moves downward through threaded cooperation and pushes the circular torsion block 506 at the bottom to continuously approach the processing table 1 and tightly contact the processing table 1. By rotating the threaded through rod 505 to push the circular torsion block 506 at the bottom to apply pressure to the processing table 1, the concave plate 503 with adjusted angle is fixed. When the threaded through rod 505 rotates, the corrugated ring 507 at the top is compressed by the circular torsion block 506, driving the corrugated ring 507 at the bottom to extend. By arranging the corrugated ring 507 between the docking circular block 508 and the circular torsion block 506, the threaded through rod 505 is wrapped and protected. The rotation of the circular torsion block 506 drives the corrugated ring 507 and the docking circular block 508 to rotate together.

[0031] Please refer to Figures 1 - 8, the present invention provides an outer wrapping tape winding device for transformer core assembly: The lubricating device 6 includes an arc-shaped connecting rod 601. One end of the arc-shaped connecting rod 601 is fixedly connected to a square thick plate 602. On the side of the square thick plate 602 away from the arc-shaped connecting rod 601, a side groove 603 is fixedly connected. The inner wall of the side groove 603 is fixedly connected to a first sponge 604. An oil seepage circular groove 605 is opened on the inner wall of the side groove 603. An concave inner groove 606 is opened on the inner wall of the oil seepage circular groove 605. A concave folding plate 607 is slidably connected to the inner wall of the concave inner groove 606. A curved inclined hole 608 is opened on the outer surface of the concave folding plate 607. The top of the concave folding plate 607 is fixedly connected to a top connecting rod 609. The top of the top connecting rod 609 is fixedly connected to a top connecting block 610. The bottom of the top connecting block 610 is fixedly connected to an electric push rod 611. The bottom of the electric push rod 611 is fixedly connected to a bottom fixing block 612. The top of the square thick plate 602 is penetrated and threadedly connected with a threaded plug 613. The end of the arc-shaped connecting rod 601 away from the square thick plate 602 is fixedly connected to one side of the concave plate 503. There are multiple oil seepage circular grooves 605, and the multiple oil seepage circular grooves 605 are distributed on the inner wall of the side groove 603. The concave folding plate 607 is a concave plate body with a V-shaped cross-section. The top of the top connecting rod 609 penetrates the concave inner groove 606 and extends to the top of the square thick plate 602. The top of the bottom fixing block 612 is fixedly connected to the bottom of the square thick plate 602;

[0032] The oil absorption device 7 includes a vertical support plate 701. On one side of the vertical support plate 701, an electric push rod two 702 is fixedly connected. The driving shaft of the electric push rod two 702 penetrates through the vertical support plate 701 and is fixedly connected with a docking square plate 703. On the top of the docking square plate 703, a small electric slide rail 704 is fixedly connected. At the bottom of the small electric slide rail 704, a bottom slide plate 705 is slidably connected. On one side of the bottom slide plate 705, a side connecting rod 706 is fixedly connected. At the end of the side connecting rod 706 away from the bottom slide plate 705, an inner sliding round block 707 is fixedly connected. The outer side of the inner sliding round block 707 is sleeved and slidably connected with a circular sleeve 708. On the side of the docking square plate 703 close to the bottom slide plate 705, a second sponge 709 is fixedly connected. On one side of the second sponge 709, a circular through hole 710 is opened. On one side of the vertical support plate 701, an oil collecting shell 711 penetrates and is slidably connected. On both sides of the oil collecting shell 711, a T-shaped sliding rod 712 is fixedly connected. The bottom of the vertical support plate 701 is fixedly connected with the top of the processing table 1. There are two bottom slide plates 705, and the two bottom slide plates 705 are distributed on both sides of the second sponge 709. The end of the side connecting rod 706 close to the inner sliding round block 707 penetrates through the circular sleeve 708 and is slidably connected with the circular sleeve 708. The outer side of the circular sleeve 708 is slidably connected with the inner wall of the circular through hole 710. One end of the T-shaped sliding rod 712 penetrates through the vertical support plate 701 and is slidably connected with the vertical support plate 701. During use, the tape passes through the inside of the concave plate 503 and then slidably contacts the first sponge 604. The top connecting block 610 is pushed upward by the electric push rod one 611 to drive the top connecting rod 609 to move upward. The upward movement of the top connecting rod 609 drives the concave folding plate 607 to move upward together. When the concave folding plate 607 moves upward, the lubricating oil in the area of the inner wall of the concave inner groove 606 close to the oil seepage circular groove 605 is pushed, so that the lubricating oil passes through the oil seepage circular groove 605 and enters the first sponge 604. By opening a curved inclined hole 608 in the concave folding plate 607, it is convenient for the lubricating oil to pass through and freely distribute in the upper and lower areas of the concave folding plate 607. The first sponge 604 filled with lubricating oil coats the tape when it contacts the back of the tape. By opening a plurality of oil seepage grooves with smaller apertures on the inner wall of the side groove 603, a small amount of lubricating oil is discharged when it is not pushed. When the tape passes through a plurality of transmission rollers and moves to a position close to the transformer core, the docking square plate 703 is pushed by driving the driving shaft through the electric push rod two 702, so that the second sponge 709 gradually approaches the tape and contacts the back of the tape. When the second sponge 709 contacts the back of the tape, it absorbs and wipes the lubricating oil on its surface. When the second sponge 709 reaches the saturation state after absorbing and wiping the lubricating oil on the tape for a long time, the docking square plate 703 is driven by the driving shaft through the electric push rod to move the second sponge 709 to the position above the oil collecting shell 711. At this time, the two bottom slide plates 705 are driven by the small electric slide rail 704 to move towards each other to compress the second sponge 709. The two bottom slide plates 705 move towards each other to compress the second sponge 709, and the absorbed lubricating oil inside is squeezed out and discharged into the oil collecting shell 711.When the bottom-mounted slide plate 705 moves, it drives the side link 706 on one side to move into the circular sleeve 708 together. When the bottom-mounted slide plate 705 moves to contact the circular sleeve 708, it is resisted and stops. By setting the circular sleeve 708 in the circular through hole 710 opened in the second sponge 709, the movement of the bottom-mounted slide plates 705 on both sides is limited. After a large amount of lubricating oil in the second sponge 709 is squeezed out, the small electric slide rail 704 drives the two bottom-mounted slide plates 705 at the bottom to move away from the circular sleeve 708. When the two bottom-mounted slide plates 705 move away from each other, they stretch the second sponge 709 to facilitate the second sponge 709 to recover to its original shape. When the bottom-mounted slide plate 705 moves, it drives the side link 706 on one side to move together. When the side link 706 moves, it drives the inner sliding round block 707 at one end to move together. When the inner sliding round block 707 moves to the end position of the circular sleeve 708, it stops. By setting the inner sliding round block 707 at one end of the side link 706, the position of the bottom-mounted slide plate 705 moving outward is limited.,

[0033] When the present invention is in operation, when the processing table 1 drives the pulling of the film 4 to wind the transformer core, the reel 3 rotates together. The tape unwound from the film 4 passes through the dust cleaning device 5 during movement and undergoes dust cleaning treatment by the dust cleaning device 5. The non-adhesive side of the back of the tape contacts the lubricating device 6. When the tape moves, the lubricating device 6 lubricates the back of the tape. When the tape passes near the transformer core through the transmission roller, it will contact the oil absorption device 7 and the lubricating oil on the back of the tape is wiped and absorbed. After the tape is wound, it can be cut and separated by the electric cutter 2. The tape passes through the built-in brush 504 inside the concave plate 503 after being unwound from the film 4 outside the reel 3 and then contacts the lubricating device 6. By arranging the built-in brush 504 inside the concave plate 503, the surface of the tape moving after unwinding is cleaned of dust. When adjusting the tension of the tape by changing the position of the transmission roller, the concave plate 503 is rotated by rotating the fixed collar 501 to adjust to a position aligned with the tape. After adjusting the position of the concave plate 503 by rotating the fixed collar 501, the circular torsion block 506 at the top is rotated to drive the threaded through rod 505 to rotate. When the threaded through rod 505 rotates, it moves downward through thread cooperation and pushes the circular torsion block 506 at the bottom to continuously approach the processing table 1 and tightly contact the processing table 1. By rotating the threaded through rod 505 to push the circular torsion block 506 at the bottom to press on the processing table 1, the concave plate 503 with adjusted angle is fixed. When the threaded through rod 505 rotates, the waveform ring plate 507 at the top is compressed by the circular torsion block 506, driving the waveform ring plate 507 at the bottom to stretch. By arranging the waveform ring plate 507 between the docking circular block 508 and the circular torsion block 506, the threaded through rod 505 is wrapped and protected. The circular torsion block 506 rotates to drive the waveform ring plate 507 and the docking circular block 508 to rotate together. The tape slides into contact with the first sponge 604 after passing through the inside of the concave plate 503. The electric push rod 611 pushes the top connecting block 610 upward to drive the top connecting rod 609 to move upward. When the top connecting rod 609 moves upward, the concave folding plate 607 moves upward together. When the concave folding plate 607 moves upward, the lubricating oil in the inner wall of the concave inner groove 606 near the oil seepage circular groove 605 area is pushed, so that the lubricating oil passes through the oil seepage circular groove 605 and enters the first sponge 604. By opening the curved inclined holes 608 in the concave folding plate 607, it is convenient for the lubricating oil to pass through and freely distribute in the upper and lower areas of the concave folding plate 607. The first sponge 604 filled with lubricating oil coats the back of the tape when contacting it. By opening a plurality of oil seepage grooves with smaller apertures on the inner wall of the side groove 603, a small amount of lubricating oil is discharged when not being pushed. When the tape passes through a plurality of transmission rollers and moves to a position near the transformer core, the electric push rod 702 drives the drive shaft to push the docking square plate 703, so that the second sponge 709 gradually approaches the tape and contacts the back of the tape. When the second sponge 709 contacts the back of the tape, it absorbs and wipes the lubricating oil on its surface. When the second sponge 709 has absorbed and wiped the lubricating oil on the tape for a long time and reaches a saturated state,The electric push rod drives the drive shaft to drive the docking square plate 703, causing the second sponge 709 to move to the position on top of the oil collection shell 711. At this time, the small electric slide rail 704 drives the two bottom-mounted slide plates 705 to move towards each other to compress the second sponge 709. When the two bottom-mounted slide plates 705 move towards each other to compress the second sponge 709, the lubricating oil absorbed inside is squeezed out and discharged into the oil collection shell 711. When the bottom-mounted slide plate 705 moves, it drives the side connecting rod 706 on one side to move into the circular sleeve 708 together. When the bottom-mounted slide plate 705 moves to contact the circular sleeve 708, it is resisted and stops. By arranging the circular sleeve 708 in the circular through hole 710 opened in the second sponge 709, the movement of the two bottom-mounted slide plates 705 on both sides is limited. After a large amount of lubricating oil in the second sponge 709 is squeezed out, the small electric slide rail 704 drives the two bottom-mounted slide plates 705 at the bottom to move away from the circular sleeve 708. When the two bottom-mounted slide plates 705 move away from each other, they stretch the second sponge 709 to facilitate the second sponge 709 to recover to its original shape. When the bottom-mounted slide plate 705 moves, it drives the side connecting rod 706 on one side to move together. When the side connecting rod 706 moves, it drives the inner sliding round block 707 at one end to move together. When the inner sliding round block 707 moves to the end position of the circular sleeve 708, it stops. By arranging the inner sliding round block 707 at one end of the side connecting rod 706, the position of the bottom-mounted slide plate 705 moving outwards is limited.
