Description

Technical Field

[0001] The present invention relates to the field of electrolytic copper foil equipment, and particularly to a submerged roll sealing structure of an after-treatment device for electrolytic copper foil. Background Art

[0002] When electrolytic copper foil is subjected to surface treatment, it is necessary to control the copper foil to pass through an electrolyte tank to complete the surface treatment. In order to ensure that the surface treatment effect of the copper foil is relatively uniform, the transported copper foil needs to be tensioned by a rotating roll for tensioning to avoid wrinkles, folds, etc. on the copper foil, such as the content shown in the patent with the application publication number CN119221054A.

[0003] In the existing surface treatment equipment, the rotating roll is usually directly rotatably connected to the box body, and a sealing ring is provided at the end of the rotating roll to closely adhere to the box body to achieve sealing; however, due to the continuous rotation of the rotating roll, the sealing ring continuously rubs against the inner wall of the box body. On the other hand, due to the electrolytic process inside the box body, electrolytic deposition is likely to occur, and in addition, the electrolyte and electrolytic process will also corrode the metal box body, making the inner wall of the box body relatively rough. When the rough inner wall of the box body rotates and rubs against the sealing ring, the service life of the sealing ring will be greatly reduced, affecting the sealing effect and easily causing electrolyte leakage. On the other hand, since the sealing ring is sleeved on the rotating roll, when replacing the sealing ring, it is necessary to remove the rotating roll, then sleeve on a new sealing ring, and then reinstall the rotating roll. The whole process is relatively cumbersome and time-consuming. Especially, the end of the rotating roll is usually also connected to external transmission structures such as belt pulleys, further increasing the difficulty of disassembly. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and provide a submerged roll sealing structure of an after-treatment device for electrolytic copper foil.

[0005] To solve the above problems, the present invention adopts the following scheme: A submerged roll sealing structure of an after-treatment device for electrolytic copper foil, comprising a rotating roll and a box body, wherein the rotating roll is rotatably arranged inside the box body; a detachable cover plate is provided at the part of the box body where the rotating roll is located, and the cover plate is fixedly connected to the connection port on the box body; a rotating hole for passing through and rotatably connecting the rotating roll is provided on the cover plate; one end of the rotating roll passes through the rotating hole and is rotatably connected to the rotating hole; a toughened glass surrounding the rotating hole is fixedly provided on the inner side of the cover plate close to the box body; the surface of the toughened glass is smooth; a plurality of first sealing gaskets are sleeved on the rotating roll, and the first sealing gaskets are located between the rotating roll and the toughened glass; the first sealing gasket closest to the toughened glass closely adheres to the toughened glass to achieve sealing; a pulling member for pushing out the first sealing gasket is further provided on the rotating roll, and the pulling member is slidably sleeved in the concave hole at the end of the rotating roll.

[0006] Further, the rotating roller includes two parts, namely a roller body and a shaft body. Both the shaft body and the roller body are cylindrical. The shaft body is symmetrically arranged at both ends of the roller body, and the roller body and the shaft body are located on the same axis. Concave holes are also provided at both ends of the roller body and recess inward.

[0007] Further, the pulling member includes a chassis and a gripping ring. The chassis is sleeved on the shaft body and is slidably arranged on the shaft body. A connecting structure is provided between the gripping ring and the chassis, and the gripping ring is located on the side of the chassis close to the tempered glass. A number of first sealing gaskets are arranged in the space between the gripping ring and the chassis.

[0008] Further, balance holes for balancing internal and external pressures are provided on the chassis; gaps for balancing pressure are also provided between the connecting structures.

[0009] Further, the connection port protrudes outward from the box body. The connection port is integrally in the shape of a cylindrical tube. An annular connection flange is provided at the end of the connection port far from the box body, and the connection flange is used for connection with the cover plate.

[0010] Further, an annular second sealing gasket is also provided between the cover plate and the connection flange.

[0011] Further, a third sealing gasket is also provided between the tempered glass and the cover plate.

[0012] Further, the first sealing gasket adopts a lip-shaped sealing gasket. The inner side of the lip-shaped sealing gasket closely adheres to the outer circumference of the rotating roller; the larger side surface of the lip-shaped sealing gasket closely adheres to the tempered glass.

[0013] Further, a liquid receiving groove is provided on the outer side of the cover plate far from the box body, and the liquid receiving groove is located below the rotating hole on the cover plate.

[0014] Further, a drain hole for draining liquid is also provided at the bottom of the liquid receiving groove.

[0015] The beneficial effects of the present invention are as follows: By providing a pulling member in cooperation with a number of first sealing gaskets, it is convenient to replace a damaged first sealing gasket with a spare first sealing gasket stored in the concave hole of the rotating roller, avoiding the cumbersome operation of removing the rotating roller and shortening the downtime; By providing a smooth tempered glass in cooperation with the first sealing gasket to form a seal, on the one hand, it ensures the sealing effect when the rotating roller is moving and stopped, and on the other hand, it can effectively extend the service life of the first sealing gasket; By providing structures for balancing pressure on the chassis and the connecting structure of the pulling member, a negative pressure space is avoided during pulling, and the pulling member can be pulled out labor-savingly, and the spare first sealing gasket stored in the concave hole can be pushed out; By providing a third sealing gasket, a seal is formed between the tempered glass and the cover plate, avoiding the leakage of electrolyte from behind the tempered glass and ensuring the sealing effect; By setting up a liquid receiving tank in cooperation with a liquid discharge hole, the leaked electrolyte can be processed in a timely manner to avoid crystallization pollution on site; By setting the shaft body of the rotating roller to include two parts with different diameters, the spare first sealing gasket is not tension-sleeved with the shaft body but remains in its original state, ensuring the service life after the replacement of the first sealing gasket.

Detailed Embodiments

[0019] The following specific examples illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0020] It should be noted that the drawings provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0021] Embodiment 1: As Figures 1 to 6As shown in the figure, a submerged roll sealing structure of an electrolytic copper foil post-treatment device includes a rotating roll 1 and a box body 2. The rotating roll 1 is rotatably arranged in the box body 2. When the rotating roll 1 rotates, it drives the tensioned copper foil to be transmitted in the box body 2 in the rotating direction. During operation, an electrolyte and an energized electrode are also arranged in the box body 2. A detachable cover plate 3 is arranged at the part of the box body 2 where the rotating roll 1 is located. The cover plate 3 is detachably connected to the connection port 21 on the box body 2. A rotating hole 31 is arranged on the cover plate 3. The end of the rotating roll 1 passes through the rotating hole 31 and is rotatably connected to the rotating hole 31. A toughened glass 4 surrounding the connection hole is fixedly arranged on the inner side of the cover plate 3 close to the box body 2. A number of first sealing gaskets 41 that fit the toughened glass 4 are sleeved on the rotating roll 1. The first sealing gaskets 41 are located between the toughened glass 4 and the rotating roll 1. The first sealing gasket 41 closest to the toughened glass 4 is in close contact with the toughened glass 4. In this example, the surface of the toughened glass 4 is smooth and can be closely attached to the first sealing gasket 41 to achieve a better sealing effect. Moreover, the glass has strong corrosion resistance and will not react with the electrolyte. Therefore, after the first sealing gasket 41 is attached to the toughened glass 4, on the one hand, it can ensure a good sealing effect, and on the other hand, it can also have a long service life.

[0022] The rotating roll 1 includes two parts, a roll body 11 and a shaft body 12. The roll body 11 is used to fit with the copper foil, and the shaft body 12 is used to rotatably connect with the box body 2. Therefore, the diameter of the roll body 11 is larger than that of the shaft body 12. An inwardly recessed hole 13 is also arranged at the end of the roll body 11. The recessed hole 13 is used to store a larger number of first sealing gaskets 41. In the traditional structure of the rotating roll 1, the edge of the roll body 11 needs to be close to the inner wall of the box body 2 so as to ensure that the copper foil transmitted in the box body 2 can contact the roll body 11 and be fully tensioned. This means that the free length at both ends of the roll body 11 is short and it is difficult to store multiple first sealing gaskets 41. Therefore, in this example, the end of the roll body 11 is set to the structure of the recessed hole 13. On the one hand, it will not affect the transmission of the copper foil, and on the other hand, there is space to store the first sealing gaskets 41. The other stored first sealing gaskets 41 can be used for replacement. After the sealing effect of the first sealing gasket 41 close to the toughened glass 4 fails, by cutting off the first sealing gasket 41 and pushing out the subsequent first sealing gaskets 41, the operation of conveniently replacing the sealing gasket is realized, greatly shortening the maintenance downtime.

[0023] A pulling member 5 for pushing out the first gasket 41 sleeved on the rotating roller 1 is further arranged on the rotating roller 1. The pulling member 5 is located at the end of the rotating roller 1. The pulling member 5 is directly sleeved on the shaft body 12 of the rotating roller 1 and is slidably arranged on the shaft body 12 for pushing out the spare first gasket 41 sleeved on the shaft body 12 from the concave hole 13, so as to facilitate the manual operation to push the replaced first gasket to the designated position. The pulling member 5 includes a chassis 51 and a gripping ring 52. The chassis 51 is sleeved on the shaft body 12 and is slidably arranged on the shaft body 12. A connecting structure 54 is arranged between the gripping ring 52 and the chassis 51. The gripping ring 52 is located on the side of the chassis 51 close to the toughened glass 4. A number of first gaskets 41 are arranged in the space between the gripping ring 52 and the chassis 51. The gripping ring 52 is integrally annular, which is convenient for the finger joints of the hand to hold the gripping ring 52 and then pull it out of the concave hole 13 to take out the first gasket 41 in the pulling member 5. The chassis 51 is integrally circular, and a number of balance holes 53 for balancing pressure are further arranged on the chassis 51. Through the balance holes 53, the pressure on both sides of the chassis 51 can be balanced, which is convenient for taking out the pulling member 5 from the concave hole 13. In this example, a gap for balancing pressure is also arranged between the connecting structures 54. The connecting structure 54 adopts a number of circumferentially closed connecting columns. The two ends of the connecting column are respectively connected to the chassis 51 and the gripping ring 52. Adjacent connecting columns are spaced at a set angle to form a gap, which is convenient for air or liquid to flow through and avoid forming a negative pressure area.

[0024] The diameter of the part of the shaft body 12 close to the concave hole 13 is smaller than the diameter of the part of the shaft body 12 close to the toughened glass 4. A chamfer is used for transition between these two parts of the shaft body 12 with different diameters. In this way, the first gasket 41 can be better restricted on the shaft body 12 with a smaller diameter in the concave hole 13, so that the spare first gasket 41 in the concave hole 13 does not form a tight sealing relationship with the shaft body 12, ensuring that the gasket in this part is not tightened and used, so that it still has a good sealing effect and a longer service life after replacement.

[0025] The connection port 21 protrudes outward from the box body 2, and the connection port 21 is integrally cylindrical and tubular; an annular connection flange 22 is provided at the end of the connection port 21 away from the box body 2, and the connection flange 22 is used to connect with the cover plate 3; the connection flange 22 is located on the outer periphery of the end of the connection port 21; the cover plate 3 and the connection flange 22 are detachably connected by a plurality of flange bolts. After removing the flange bolts, the cover plate 3 and the connection flange 22 can be separated, facilitating the adjustment of structures such as the roller 1 inside the box body 2. An annular second gasket 23 is also provided between the cover plate 3 and the connection flange 22; through holes corresponding to the flange bolts are also provided on the second gasket 23, so that the flange bolts can also be used to fix the second gasket 23. In this example, the second gasket 23 is made of ethylene propylene diene monomer (EPDM) rubber material, which has good anti-aging performance, heat resistance, insulation performance, and waterproof sealing performance.

[0026] The tempered glass 4 and the cover plate 3 are fixedly connected by screws. A third gasket 32 is also provided between the tempered glass 4 and the cover plate 3; the third gasket 32 is an O-ring seal, and the O-ring seal is also made of ethylene propylene diene monomer (EPDM) rubber material; in this example, the third gasket 32 is located between the center of the tempered glass 4 and the screws. In this way, the displacement of the O-ring seal can be restricted to a certain extent by the screws, preventing it from shifting out of the area between the tempered glass 4 and the cover plate 3; in order to better form a sealing effect, a sealing groove matching the third gasket 32 is also provided on the cover plate 3, so that the O-ring seal is embedded in the sealing groove, then contacts the tempered glass 4 on the other side, and is squeezed by the tempered glass 4 to form a seal. On the one hand, the sealing effect is improved, and on the other hand, the O-ring seal is prevented from shifting and affecting the sealing effect.

[0027] The first gasket 41 is a lip seal, and the inner side of the lip seal closely adheres to the outer periphery of the roller 1; the larger side of the lip seal closely adheres to the tempered glass 4; so that the lip seal is always pressed tightly on the roller 1 and the tempered glass 4 under the action of water pressure, forming a good sealing effect.

[0028] A liquid receiving groove 33 is provided on the outer side of the cover plate 3 away from the box body 2. The liquid receiving groove 33 is located below the through hole 31 on the cover plate 3 and is used to receive the electrolyte oozing along the through hole 31. A liquid discharge hole 34 for discharging liquid is also provided at the bottom of the liquid receiving groove 33, which can timely transport the electrolyte to the external waste liquid tank through the liquid discharge hole 34 for treatment to prevent crystallization pollution. It should be noted that the liquid discharge hole 34 in the liquid receiving groove 33 is provided in the central area near the bottom of the liquid receiving groove 33, and the bottom of the liquid receiving groove 33 is set to be funnel-shaped sunken towards the liquid discharge hole 34 to facilitate the discharge of liquid along the liquid discharge hole 34.

[0029] During the implementation process, by setting the drawer 5 in combination with multiple first sealing gaskets 41, it is convenient to store the spare first sealing gaskets 41 in the concave hole 13 of the roller 1 to replace the damaged first sealing gasket 41, thereby avoiding the tedious operation of removing the roller 1 and shortening the downtime; by setting the smooth tempered glass 4 in combination with the first sealing gasket 41 to form a seal, on the one hand, the sealing effect when the roller 1 is moving and when it stops is guaranteed, and on the other hand, the service life of the first sealing gasket 41 can be effectively extended; by setting a pressure balancing structure on the chassis 51 and the connecting structure 54 of the drawer 5, the formation of a negative pressure space when pulling is avoided , the drawer 5 can be pulled out effortlessly, and the spare first sealing gasket 41 stored in the recessed hole 13 can be pushed out; by setting the third sealing gasket 32, a seal is formed between the tempered glass 4 and the cover plate 3 to prevent the electrolyte from leaking from the rear of the tempered glass 4, thereby ensuring the sealing effect; by setting the liquid receiving groove 33 in conjunction with the liquid drain hole 34, the leaked electrolyte can be processed in time to avoid crystallization contamination on site; by setting the shaft body 12 of the rotating roller 1 to include two parts with different diameters, the spare first sealing gasket 41 is not tensioned and sleeved with the shaft body 12, but remains original, thereby ensuring the service life of the first sealing gasket 41 after replacement.

[0030] The above description is only a specific example of the present invention and does not constitute any limitation to the present invention. It is obvious that for professionals in this field, after understanding the content and principle of the present invention, various modifications and changes in form and details may be made without departing from the principle and structure of the present invention, but these modifications and changes based on the idea of ​​the present invention are still within the scope of protection of the claims of the present invention.
