Description

Technical Field

[0001] This invention relates to the field of transformer core assembly technology, specifically to an external tape winding device for transformer core assembly. Background Technology

[0002] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating varnish. Together with the coils wound on it, it forms a complete electromagnetic induction system. The core has high permeability, which enables the primary winding of the transformer to generate a large magnetic induction intensity with a small excitation current. This confines most of the magnetic lines of force within the core, allowing magnetic energy to be effectively transferred to the secondary winding, improving electromagnetic coupling efficiency, and reducing leakage flux. By properly selecting the core material and designing the magnetic circuit, magnetic saturation can be avoided during operation, ensuring the stable performance of the transformer. When assembling the transformer core, it is necessary to wrap it with tape to prevent leakage current, short circuits, and other phenomena between the winding and the core or other components.

[0003] When processing transformer cores, it is necessary to wrap them with multiple turns of outer tape. However, the unwound tape is affected by the working environment, and dust particles and impurities adhere to its surface, which affects the effect of subsequent core winding. Therefore, we have proposed an outer tape winding device for transformer core assembly. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an external tape winding device for assembling transformer cores, including a processing table, an electric cutter fixedly connected to the top of the processing table, a reel rotatably connected to the top of the processing table via a rotating bolt, a film roll sleeved and fixedly connected to the outside of the reel, a dust removal device sleeved and rotatably connected to the outside of the reel via a bearing, a lubrication device fixedly connected to the side of the dust removal device away from the reel, and an oil suction device fixedly connected to the top of the processing table.

[0005] The dust removal device includes a fixing collar. By rotating the fixing collar, the concave plate is rotated to adjust to a position aligned with the tape. This prevents the tape from bending at a large angle after tension adjustment and coming into tight friction with the concave plate, which could easily cause damage. An outer connecting rod is fixedly connected to the outer side of the fixing collar. The concave plate is fixedly connected to the end of the outer connecting rod away from the fixing collar. An internal brush is fixedly connected to the inner side of the concave plate. By setting the internal brush on the inner side of the concave plate, dust is cleaned from the surface of the tape after unwinding, preventing dust particles and impurities from adhering to the surface of the unwound tape due to the working environment, which could affect the subsequent magnetic core winding process.

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

[0007] A threaded rod is threaded through and connected to the top of the concave plate. Circular torsion blocks are fixedly connected to the top and bottom of the threaded rod. By rotating the threaded rod, the circular torsion blocks at the bottom are pushed to apply pressure to the processing table, thereby fixing the concave plate after the angle has been adjusted. This prevents the fixed collar from rotating slightly when the film roll is unwound, which would make it difficult for the built-in brush inside the concave plate to effectively contact the tape. A corrugated ring is fixedly connected to the side of the circular torsion block closest to the concave plate. By setting the corrugated ring between the mating circular block and the circular torsion block, the threaded rod is wrapped and protected, preventing dust particles that have been cleaned from adhering to the surface of the threaded rod near the built-in brush from affecting the threaded fit of the threaded rod. A mating circular block is fixedly connected to the side of the corrugated ring away from the circular torsion block.

[0008] Two threaded rods are provided, and the two threaded rods are distributed on the concave plate. The side of the mating block away from the wave ring is rotatably connected to the side of the concave plate through a bearing.

[0009] Furthermore, the lubrication device includes an arc-shaped connecting rod, one end of which 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, filled with lubricating oil, is fixedly connected to the inner wall of the side groove. When the first sponge contacts the back of the tape, it applies lubricating oil to prevent the tape from breaking easily due to repeated friction with multiple transmission rollers during movement, especially under high tension. An oil-permeable circular groove is formed on the inner wall of the side groove. Multiple small-diameter oil-seeping grooves allow lubricating oil to drain in small amounts when not being pushed, preventing large amounts of lubricating oil from continuously draining from the concave inner grooves and causing the first sponge to reach saturation and overflow when not in use. The inner wall of the oil-seeping circular groove has a concave inner groove, and a concave folding plate is slidably connected to the inner wall of the concave inner groove. When the concave folding plate moves upward, it pushes the lubricating oil near the oil-seeping circular groove area on the inner wall of the concave inner groove, allowing the lubricating oil to pass through the oil-seeping circular groove and enter the first sponge. This prevents the small diameter of the oil-seeping circular groove from causing excessive lubricating oil overflow. The infrequent oil immersion of the first sponge can lead to poor lubrication. To address this, curved oblique holes are provided on the outer surface of the concave folding plate. These holes facilitate the free distribution of lubricating oil across the upper and lower areas of the plate, preventing the lubricating oil from being pushed upwards by the folding plate and causing excessive pressure due to the large amount of oil failing to drain through the seepage grooves, thus affecting performance. A top connecting rod is fixedly connected to the top of the concave folding plate, and a top connecting block is fixedly connected to the top of the top connecting rod. The bottom of the top connecting block is fixedly connected to... An electric push rod is provided, with a bottom fixing block fixedly connected to its bottom. A threaded plug is threaded through and 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 concave plate. Multiple oil seepage grooves are provided, and the multiple oil seepage grooves are distributed on the inner wall of the side groove. The concave folding plate is set as a concave plate with a V-shaped cross section. The top of the top connecting rod passes through the concave inner 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] Furthermore, the oil-absorbing device includes a vertical support plate. An electric push rod is fixedly connected to one side of the vertical support plate. The drive shaft of the electric push rod passes through the vertical support plate and is fixedly connected to a docking plate. A small electric slide rail is fixedly connected to the top of the docking plate. A bottom sliding plate is slidably connected to the bottom of the small electric slide rail. The two bottom sliding plates move towards each other, compressing the second sponge and squeezing out the absorbed lubricating oil into the oil collection shell. This prevents the second sponge from becoming saturated with lubricating oil after prolonged use, making it difficult to absorb lubricating oil from the back of the tape. A side connecting rod is fixedly connected to one side of the bottom sliding plate. An inner sliding block is fixedly connected to the end of the side connecting rod away from the bottom sliding plate. By setting the inner sliding block at one end of the side connecting rod, the outward movement of the bottom sliding plate is limited, preventing excessive stretching of the second sponge when it moves outward, which would lead to poor oil absorption and affect its use. A circular sleeve is fitted and slidably connected to the outer side of the inner sliding block. The circular sleeve is placed inside the circular through-hole of the second sponge to... The bottom sliding plates on both sides are moved and limited to prevent excessive compression of the second sponge when it is compressed, which would gradually damage the sponge and make it unusable. The second sponge is fixedly connected to the side of the docking plate near the bottom sliding plate. When the second sponge comes into contact with the back of the tape, the lubricating oil on its surface is absorbed and wiped off to prevent the back of the tape to be wrapped from still having a large amount of lubricating oil, which would make it difficult to wrap the tape tightly and affect the winding effect on the transformer core. A circular through hole is opened on one side of the second sponge. An oil collection shell is slidably connected through one side of the vertical support plate. 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 sliding plates, which are distributed on both sides of the second sponge. The end of the side connecting rod near the inner sliding block passes through the circular sleeve and is slidably connected to the circular sleeve. The outer side of the circular sleeve is slidably connected to the inner wall of the circular through hole. One end of the T-shaped sliding rod passes through the vertical support plate and is slidably connected to the vertical support plate.

[0011] This invention provides an external tape wrapping device for assembling transformer cores. It has the following advantages:

[0012] 1. The transformer core assembly external tape winding equipment uses a built-in brush on the inner side of the concave plate to clean the dust from the surface of the unwound tape after it moves. This prevents the unwound tape from being affected by dust particles and impurities on its surface due to the working environment, which would affect the subsequent winding effect on the core. A first sponge filled with lubricating oil applies lubricating oil to the back of the tape when it comes into contact with it, preventing the tape from breaking easily due to repeated friction with multiple drive rollers during movement, especially when the tension is high. When the second sponge comes into contact with the back of the tape, it absorbs and wipes off the lubricating oil on its surface, preventing the back of the tape to be wound from still having a large amount of lubricating oil adhering to it, which would make it difficult to wind the tape tightly and affect the winding effect on the transformer core.

[0013] 2. The transformer core assembly tape winding equipment is equipped with a dust removal device. An internal brush on the inner side of the concave plate cleans the surface of the unwound tape, preventing dust particles from adhering to the tape surface due to the working environment and affecting the subsequent core winding process. Rotating the fixing ring rotates the concave plate to adjust it to a position aligned with the tape, preventing damage caused by excessive bending angle and tight friction between the tape and the concave plate after tension adjustment. Rotating the threaded rod pushes the bottom circular torsion block to apply pressure to the processing table, fixing the adjusted concave plate. This prevents slight rotation of the fixing ring during unwinding, which could hinder effective contact between the internal brush and the tape. A corrugated ring between the mating block and the circular torsion block protects the threaded rod, preventing dust particles near the internal brush from affecting the thread fit.

[0014] 3. The outer tape winding device for assembling the transformer core is equipped with a lubrication system. When the concave folding plate moves upward, it pushes the lubricating oil near the oil seepage groove area on the inner wall of the concave inner groove, allowing the lubricating oil to pass through the oil seepage groove and enter the first sponge. This prevents the lubricating oil from overflowing due to the small diameter of the oil seepage groove, which would make it difficult to ensure that the first sponge is always immersed in oil, resulting in poor lubrication. By opening curved oblique holes on the concave folding plate, the lubricating oil can pass through and be freely distributed in the upper and lower areas of the concave folding plate. This prevents the lubricating oil at the top from being pushed upward when the concave folding plate moves upward, which would cause a large amount of lubricating oil to be difficult to discharge through the oil seepage groove in time, resulting in large pressure that would affect the use. The first sponge, which is filled with lubricating oil, is coated with lubricating oil when it comes into contact with the back of the tape. This prevents the tape from breaking easily when it comes into contact with multiple transmission rollers during movement, especially when the tension is high. By opening multiple small-diameter oil seepage grooves on the inner wall of the side groove, a small amount of lubricating oil is discharged when it is not pushed. This prevents the lubricating oil from continuously flowing out of the concave inner groove in large quantities, which would cause the lubricating oil inside the first sponge to become saturated and overflow and drip downward when it is not in use.

[0015] 4. The transformer core assembly tape winding device is equipped with an oil suction device. When the second sponge comes into contact with the back of the tape, it absorbs and wipes away the lubricating oil on its surface, preventing the back of the tape from still having a large amount of lubricating oil adhering to it, which would make it difficult to wind the tape tightly and affect the winding effect on the transformer core. The two bottom sliding plates move towards each other to compress the second sponge, squeezing out the lubricating oil absorbed inside and expelling it into the oil collection shell. This prevents the second sponge from becoming saturated with lubricating oil after long-term use and becoming unable to absorb lubricating oil from the back of the tape. A circular sleeve is set in the circular through hole of the second sponge to limit the movement of the bottom sliding plates on both sides, preventing excessive compression of the second sponge when it is compressed by the bottom sliding plates, which would gradually damage the sponge and make it unusable. An inner sliding block is set at one end of the side connecting rod to limit the outward movement of the bottom sliding plates, preventing excessive stretching of the second sponge when it moves outward, which would result in poor oil absorption and affect its use.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-4 The present invention provides a device for wrapping tape for assembling transformer cores, 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 via a rotating bolt, a film roll 4 sleeved and fixedly connected to the outside of the reel 3, a dust removal device 5 sleeved and rotatably connected to the outside of the reel 3 via a bearing, a lubrication device 6 fixedly connected to the side of the dust removal 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 removal device 5 includes a fixed collar 501, an outer connecting rod 502 is fixedly connected to the outer side of the fixed collar 501, a concave plate 503 is fixedly connected to the end of the outer connecting rod 502 away from the fixed collar 501, and an internal brush 504 is fixedly connected to the inner side of the concave plate 503.

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

[0029] A threaded rod 505 is threaded through and threaded to the top of the concave plate 503. A circular torsion block 506 is fixedly connected to both the top and bottom of the threaded rod 505. A wave ring 507 is fixedly connected to the side of the circular torsion block 506 near the concave plate 503. A mating circular block 508 is fixedly connected to the side of the wave ring 507 away from the circular torsion block 506.

[0030] Two threaded rods 505 are provided, and the two threaded rods 505 are distributed on the concave plate 503. The side of the mating block 508 away from the wave ring 507 is rotatably connected to the side of the concave plate 503 through a bearing. In use, when the processing table 1 drives the film roll 4 to wind the transformer core, it drives the reel 3 to rotate together. When the film roll 4 is unwound, the tape passes through the dust removal device 5 and is cleaned of dust by the dust removal device 5. The back of the tape without adhesive contacts the lubrication device 6. The tape moves. The lubrication device 6 lubricates the back of the tape. When the tape passes the drive roller and approaches the transformer core, it comes into contact with the oil suction device 7, which wipes away and absorbs 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. After the tape is unwound from the roll 4 on the outside of the reel 3, it passes through the built-in brush 504 on the inside of the concave plate 503 and then comes into contact with the lubrication device 6. The built-in brush 504 on the inside of the concave plate 503 cleans the dust from the surface of the tape after unwinding. When the tension of the tape is changed by adjusting the position of the drive roller, the concave plate 503 is rotated by rotating the fixing collar 501 to adjust it to a position aligned with the tape. After adjusting the position of the concave plate 503 by rotating the fixing collar 501, the top circular torsion block 506 is rotated to rotate the threaded rod 505. When the threaded rod 505 rotates, it moves downward through the threaded engagement and pushes the bottom circular torsion block 506 closer to the processing table 1 and into tight contact with the processing table 1. 05. The bottom circular torsion block 506 is pushed to apply pressure to the processing table 1 to fix the concave plate 503 after the angle has been adjusted. When the threaded rod 505 rotates, the circular torsion block 506 compresses the top wave-shaped ring 507, causing the bottom wave-shaped ring 507 to extend. The threaded rod 505 is wrapped and protected by the wave-shaped ring 507 set between the docking round block 508 and the circular torsion block 506. The rotation of the circular torsion block 506 causes the wave-shaped ring 507 and the docking round block 508 to rotate together.

[0031] Please see Figures 1-8This invention provides an outer tape wrapping device for transformer core assembly: a lubrication device 6 includes an arc-shaped connecting rod 601, one end of which is fixedly connected to a square thick plate 602. A side groove 603 is fixedly connected to the side of the square thick plate 602 away from the arc-shaped connecting rod 601. A first sponge 604 is fixedly connected to the inner wall of the side groove 603. An oil-permeable circular groove 605 is formed on the inner wall of the oil-permeable circular groove 605. A concave inner groove 606 is formed on the inner wall of the concave inner groove 606. A concave folding plate 607 is slidably connected to the inner wall of the concave folding plate 607. A curved oblique hole 608 is formed on the outer surface of the concave folding plate 607. A top connecting rod 609 is fixedly connected to the top of the concave folding plate 607. A top connecting block 610 is connected, and an electric push rod 611 is fixedly connected to the bottom of the top connecting block 610. A bottom fixing block 612 is fixedly connected to the bottom of the electric push rod 611. A threaded plug 613 is threaded through and threadedly connected to the top of the square thick plate 602. 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. Multiple oil seepage grooves 605 are provided, and the multiple oil seepage grooves 605 are distributed on the inner wall of the side groove 603. The concave folding plate 607 is set as a concave plate 503 body with a V-shaped cross section. The top of the top connecting rod 609 passes through 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 suction device 7 includes a vertical support plate 701. An electric push rod 702 is fixedly connected to one side of the vertical support plate 701. The drive shaft of the electric push rod 702 passes through the vertical support plate 701 and is fixedly connected to a docking plate 703. A small electric slide rail 704 is fixedly connected to the top of the docking plate 703. A bottom sliding plate 705 is slidably connected to the bottom of the small electric slide rail 704. A side connecting rod 706 is fixedly connected to one side of the bottom sliding plate 705. An inner sliding block 707 is fixedly connected to the end of the side connecting rod 706 away from the bottom sliding plate 705. A circular sleeve 708 is fitted and slidably connected to the outer side of the inner sliding block 707. A second sponge 709 is fixedly connected to the side of the docking plate 703 near the bottom sliding plate 705. A section is opened on one side of the second sponge 709. A circular through-hole 710 is provided. An oil collection shell 711 is slidably connected to one side of a vertical support plate 701. T-shaped slide rods 712 are fixedly connected to both sides of the oil collection shell 711. The bottom of the vertical support plate 701 is fixedly connected to the top of the processing table 1. Two bottom sliding plates 705 are provided, and the two bottom sliding plates 705 are distributed on both sides of the second sponge 709. One end of the side connecting rod 706 near the inner sliding block 707 passes through a circular sleeve 708 and is slidably connected to the circular sleeve 708. The outer side of the circular sleeve 708 is slidably connected to the inner wall of the circular through-hole 710. One end of the T-shaped slide rod 712 passes through the vertical support plate 701 and is slidably connected to the vertical support plate 701. In use, the tape passes through the inner side of the concave plate 503 and then slides into contact with the first sponge 604. The electric push rod 611 pushes the top connecting block 610 upward, causing the top connecting rod 609 to move upward. The upward movement of the top connecting rod 609 causes the concave folding plate 607 to move upward as well. When the concave folding plate 607 moves upward, it pushes the lubricating oil in the area near the oil seepage groove 605 on the inner wall of the concave inner groove 606, allowing the lubricating oil to pass through the oil seepage groove 605 and enter the first sponge 604. By opening curved oblique holes 608 on the concave folding plate 607, the lubricating oil can pass through and be freely distributed in the upper and lower areas of the concave folding plate 607. The first sponge 604, which is filled with lubricating oil, coats the back of the tape with lubricating oil when it comes into contact with it. By opening multiple small-diameter oil seepage grooves on the inner wall of the side groove 603, a small amount of lubricating oil is discharged when it is not pushed. The tape moves through multiple drive rollers to approach the variable When the magnetic core of the compressor is positioned, the electric push rod 702 drives the drive shaft to push the docking plate 703, causing the second sponge 709 to gradually approach the tape and contact the back of the tape. When the second sponge 709 contacts the back of the tape, it absorbs and wipes away the lubricating oil on its surface. When the second sponge 709 reaches saturation after absorbing and wiping away the lubricating oil for a long time, the electric push rod drives the drive shaft to move the docking plate 703, causing the second sponge 709 to move to the top position of the oil collection shell 711. At this time, the small electric slide rail 704 drives the two bottom sliding plates 705 to move towards each other to compress the second sponge 709. The two bottom sliding plates 705 moving towards each other compress the second sponge 709, squeezing out the lubricating oil absorbed inside and expelling it into the oil collection shell 711.When the bottom sliding plate 705 moves, it drives the side connecting rod 706 on one side to move into the circular sleeve 708. The bottom sliding plate 705 stops when it contacts the circular sleeve 708. The circular sleeve 708 is installed in the circular through hole 710 of the second sponge 709 to limit the movement of the bottom sliding plates 705 on both sides. After a large amount of lubricating oil in the second sponge 709 is squeezed out, the two bottom sliding plates 705 at the bottom move away from the circular sleeve 708 through the small electric slide rail 704. When the two bottom sliding plates 705 move in opposite directions, they stretch the second sponge 709 to help it return to its initial shape. The movement of the bottom sliding plates 705 also moves the side connecting rod 706 on one side, which in turn moves the inner sliding block 707 at one end. The inner sliding block 707 stops when it reaches the end of the circular sleeve 708. The inner sliding block 707 at one end of the side connecting rod 706 limits the outward movement of the bottom sliding plates 705.

[0033] In operation, the processing table 1 pulls the film roll 4 to wind the transformer core, causing the reel 3 to rotate as well. As the film roll 4 unwinds, it passes through the dust removal device 5, where dust is removed. The back of the film, the side without adhesive, contacts the lubrication device 6, which lubricates the back of the film as it moves. When the film roll approaches the transformer core via the drive roller, it contacts the oil suction device 7, which removes and absorbs the lubricating oil from the back of the film. After winding, the film roll 2 cuts it. The film roll 4, unwound from the outside of the reel 3, passes through the built-in brush 504 inside the concave plate 503 before contacting the lubrication device 6. The built-in brush 504 inside the concave plate 503 provides this functionality. After unwinding, the surface of the moving tape is cleaned of dust. When adjusting the tension of the tape by changing the position of the drive roller, the fixed collar 501 is rotated to drive the concave plate 503 to rotate and adjust it to be aligned with the tape. After adjusting the position of the concave plate 503 by rotating the fixed collar 501, the top circular torsion block 506 is rotated to drive the threaded rod 505 to rotate. When the threaded rod 505 rotates, it moves downwards through the threaded engagement and pushes the bottom circular torsion block 506 closer to the processing table 1 until it comes into tight contact with the processing table 1. By rotating the threaded rod 505, the bottom circular torsion block 506 is pushed against the processing table 1 to fix the concave plate 503 after the angle adjustment. When the threaded rod 505 rotates, the circular torsion block 506 presses against the top... The corrugated ring 507 is compressed, causing the bottom corrugated ring 507 to extend. The corrugated ring 507 is placed between the mating round block 508 and the circular torsion block 506 to wrap and protect the threaded rod 505. The rotation of the circular torsion block 506 causes the corrugated ring 507 and the mating round block 508 to rotate together. After the tape passes through the inner side of the concave plate 503, it slides into contact with the first sponge 604. The electric push rod 611 pushes the top connecting block 610 upward, causing the top connecting rod 609 to move upward. The upward movement of the top connecting rod 609 causes the concave folding plate 607 to move upward together. When the concave folding plate 607 moves upward, it pushes the lubricating oil in the area near the oil seepage groove 605 on the inner wall of the concave inner groove 606, allowing the lubricating oil to pass through the oil seepage groove 605 and enter the first sponge 604. By creating curved oblique holes 608 in the concave folding plate 607, lubricating oil can pass through and freely distribute itself in the upper and lower areas of the concave folding plate 607. A first sponge 604, filled with lubricating oil, coats the back of the tape with lubricating oil upon contact. Multiple small-diameter oil-permeable grooves are created in the inner wall of the side groove 603 to allow a small amount of lubricating oil to drain out without being pushed. When the tape moves past multiple drive rollers to a position close to the transformer core, an electric push rod 702 drives the drive shaft to push the docking square plate 703, causing the second sponge 709 to gradually approach and contact the back of the tape. When the second sponge 709 contacts the back of the tape, it absorbs and wipes away the lubricating oil. When the second sponge 709 reaches saturation after prolonged absorption and wiping of the tape with lubricating oil...The electric push rod drives the drive shaft to move the docking plate 703, causing the second sponge 709 to move to the top of the oil collection shell 711. At this time, the small electric slide rail 704 drives the two bottom sliding plates 705 to move towards each other to compress the second sponge 709. The movement of the two bottom sliding plates 705 towards each other compresses the second sponge 709, squeezing out the lubricating oil absorbed inside and expelling it into the oil collection shell 711. When the bottom sliding plates 705 move, they drive the side connecting rod 706 on one side to move into the circular sleeve 708. The bottom sliding plates 705 stop when they contact the circular sleeve 708. The circular sleeve 708 is installed in the circular through hole 710 of the second sponge 709 to compress the bottom sliding plates on both sides. After the plate 705 is moved and limited, a large amount of lubricating oil in the second sponge 709 is squeezed out. Then, the two bottom sliding plates 705 move away from the circular sleeve 708 via the small electric slide rail 704. When the two bottom sliding plates 705 move in opposite directions, they stretch the second sponge 709, allowing it to return to its initial shape. The movement of the bottom sliding plates 705 also moves the side connecting rod 706 on one side. The movement of the side connecting rod 706 also moves the inner sliding block 707 at one end. The inner sliding block 707 stops when it reaches the end of the circular sleeve 708. The inner sliding block 707 at one end of the side connecting rod 706 limits the outward movement of the bottom sliding plates 705.
