Description

Technical Field

[0001] This utility model belongs to the field of industrial aluminum foil production technology, and specifically relates to an automatic descaling device for a submersible transmission roller. Background Technology

[0002] In the production of aluminum foil and bright foil, aluminum foil requires pretreatment via a submersible conveyor. During the rolling process, submersible conveyors are sometimes used to provide a stable rolling environment. Submersible conveyors help maintain stable tension in the aluminum foil, preventing wrinkles or cracks from forming during rolling.

[0003] During the underwater transmission process of aluminum foil, aluminum powder or other impurities may fall off, and these aluminum powder impurities will form aluminum scale on the transmission roller at the bottom of the water tank.

[0004] However, existing underwater transmission mechanisms lack simple and effective descaling methods, making it impossible to reliably remove aluminum scale and impurities from the transmission rollers. This may affect product quality and cause serious losses. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an automatic descaling device for a submersible drive roller.

[0006] To achieve the innovative objectives of this utility model, the following technical solutions can be used:

[0007] An automatic descaling device for a submersible drive roller includes a frame on which a horizontal drive roller is rotatably connected. A friction roller is positioned above the drive roller and is slidably connected to the frame, moving freely up and down. The friction roller is in close contact with the drive roller by gravity. The drive roller and the friction roller are submerged below the surface of a cleaning water tank, which is connected to a water circulation filtration mechanism.

[0008] This utility model's automatic descaling device can be used to remove and prevent scale buildup on the drive rollers of submersible transmission systems, such as removing aluminum scale from aluminum foil submersible drive rollers. This is mainly achieved through a friction roller, which adheres to the drive roller by gravity. This friction roller can accommodate drive rollers of different sizes and compensate for wear caused by prolonged use, ensuring stable contact between the two. It also provides minimal resistance to the rotation of the drive roller. As the drive roller rotates, the friction roller scrapes off or disperses the scale impurities on it, helping the circulating water in the cleaning tank to flush away the aluminum scale impurities, thus cleaning the drive roller. The water circulation and filtration mechanism is used to circulate and filter the water in the cleaning tank. This circulation is pressurized, which helps to flush away impurities and filter out the aluminum scale impurities. The filtered clean water then re-enters the circulation, saving water resources.

[0009] In the above-mentioned automatic descaling device for submersible transmission rollers, the frame is provided with a vertically extending and open upper groove, and a slider is slidably connected in the groove. The two ends of the friction roller are respectively connected to the two sliders.

[0010] The friction roller is slidably connected to the slide groove via a slider. The slide groove extends vertically, allowing the friction roller to move vertically up and down, ensuring the stable and tight contact of the friction roller with the gravity-driven roller.

[0011] In the above-mentioned automatic descaling device for submersible transmission rollers, the slider is provided with a connecting hole, and the end of the friction roller is inserted into the connecting hole and is limited in rotation; or the end of the friction roller is rotatably connected to the connecting hole through a bearing and can rotate freely.

[0012] The connection between the end of the friction roller and the connecting hole can be a rotation limit, meaning the friction roller cannot rotate. In this case, the friction roller mainly removes aluminum scale impurities from the transmission roller by scraping. Alternatively, it can be a rotational connection, meaning the friction roller can rotate with the transmission roller. This reduces the rotational resistance and wear on the transmission roller, and removes aluminum scale impurities mainly by crushing the side wall of the transmission roller to disperse the aluminum scale and help the circulating water flush it away.

[0013] In the above-mentioned automatic descaling device for the submersible drive roller, a gravity drop body is detachably connected to the outside of the slider.

[0014] Alternatively, a pressure spring is provided between the slider and the frame, with the upper end of the pressure spring connected to a first hook on the outside of the slider and the lower end connected to a second hook on the outside of the frame, wherein one or more second hooks are distributed along the length of the slide groove.

[0015] The gravity-fed weights or pressure springs increase the pressure between the drive roller and the friction roller, ensuring stable contact and engagement between them. Furthermore, the number of gravity-fed weights and the hook position at the lower end of the pressure springs can be adjusted, facilitating flexible adjustment of the pressure.

[0016] In the above-mentioned automatic descaling device for submersible transmission rollers, the friction roller is cylindrical and has a longitudinal corrugated structure on its side wall. The friction roller is rotatably connected to the frame.

[0017] The friction roller is equipped with a longitudinal corrugated structure. When the friction roller rolls over the drive roller, the texture presses on the corresponding position on the side wall of the drive roller. With continuous rotation, the aluminum scale on the side wall of the drive roller is broken down and dispersed, which is conducive to the circulating water washing down and carrying away the aluminum scale impurities.

[0018] In the above-mentioned automatic descaling device for submersible drive rollers, the water circulation filtration mechanism includes a water circulation power component and a filtration component. The cleaning water tank is provided with an inlet and an outlet. The outlet is connected to the inlet through a circulation pipeline. The circulation pipeline is provided with a filtration component and a water circulation power component.

[0019] The water circulation power unit provides the power required for water circulation. A circulating water pump can be selected. The inlet on the cleaning water tank is used to input filtered clean water, and the outlet is used to output wastewater that may carry aluminum scale impurities. The filter assembly is used to filter out aluminum scale impurities from the wastewater, achieving a closed-loop connection and ensuring the cleanliness of the drive roller. The filter assembly and water circulation power unit are common knowledge and will not be elaborated on in detail.

[0020] In the above-mentioned automatic descaling device for the submersible drive roller, the water inlet is located at the lower part of the side wall of the cleaning water tank, and the water outlet is located at the upper part of the side wall of the cleaning water tank, and is diagonally distributed with respect to the water inlet.

[0021] The inlet and outlet are diagonally distributed, which makes the circulating water flow from bottom to top through the contact surface of the friction roller and the drive roller, which helps the circulating water to wash away the aluminum scale and impurities removed from the drive roller in a timely manner.

[0022] In the above-mentioned automatic descaling device for the submersible drive roller, the inlet and outlet are located in the axial direction of the drive roller and are both facing the contact position of the drive roller and the friction roller. The inlet is lower than or flush with the outlet.

[0023] As an optimization, the inlet and outlet can also be set at both ends of the drive roller, with the inlet not higher than the outlet, so that the circulating water flows directly through the contact surface of the drive roller and the friction roller, which is conducive to timely flushing away aluminum scale and reducing the possibility of aluminum scale depositing between the strip and the drive strip.

[0024] In the above-mentioned automatic descaling device for submersible transmission rollers, the cleaning water tank is located inside the outer water tank, the outer water tank is provided with an overflow port, the cleaning water tank is provided with an outlet and an inlet, the overflow port is connected to the inlet through a circulation pipeline, and the circulation pipeline is provided with a water circulation power component and a filter component.

[0025] The cleaning water tank is equipped with an external water tank. Wastewater flowing out of the cleaning water tank outlet first enters the external water tank, and then enters the circulation pipeline through the overflow port. This ensures that there are no impurities left in the tank liquid at the transmission roller and friction roller, effectively reducing the risk of scaling. Moreover, the filtration and belt transmission process will take away a small amount of water. This reduction in water volume is reflected in the liquid level of the external water tank, without affecting the water volume in the cleaning water tank, thus ensuring the descaling and cleaning effect.

[0026] In the above-mentioned automatic descaling device for submersible drive rollers, the cleaning water tank includes a closed tank body. The top of the tank body is provided with a strip through hole and a frame through hole. The strip conveyed on the drive roller passes through the strip through hole, and the frame passes through the frame through hole and extends into the tank. The water outlet and water inlet are located on the side wall of the closed tank body, with the water outlet being higher than the water inlet and the overflow port being higher than the water outlet.

[0027] The main body of the cleaning water tank is a rectangular, enclosed box, which helps reduce the residue of impurities inside. The strip passages on the tank are adapted to the width and thickness of the conveyor belt, and the shape and size of the frame passages are adapted to the corresponding size of the frame, ensuring the conveying of the strip and the installation of the drive rollers and friction rollers on the frame. Of course, the top plate of the tank is removable, which facilitates initial installation and subsequent maintenance. In addition, the overflow port is higher than the outlet port, meaning that the cleaning water tank is submerged below the liquid surface of the water tank, which helps to ensure a stable water volume in the cleaning water tank.

[0028] Compared with the prior art, the present invention has the following main advantages:

[0029] 1. The friction roller is pressed against the drive roller by gravity, which can adapt to drive rollers of different sizes and compensate for wear caused by long-term use, ensuring stable contact between the two. At the same time, it provides less resistance to the rotation of the drive roller. As the drive roller rotates, the friction roller scrapes off or disperses the scale and impurities on the drive roller, which helps to flush away aluminum scale and impurities in the circulating water in the cleaning tank.

[0030] 2. The gravity dropper or pressure spring increases the pressure between the drive roller and the friction roller, ensuring stable contact and cooperation between the two. Moreover, the number of gravity droppers and the hook position at the lower end of the pressure spring can be adjusted, making it easy to flexibly adjust the pressure.

[0031] 3. The friction roller is equipped with a longitudinal corrugated structure. When the friction roller rolls over the drive roller, the texture presses against the side wall of the drive roller. With each rotation, the aluminum scale on the side wall of the drive roller is broken down and dispersed, which is beneficial for the circulating water to wash away the aluminum scale impurities.

[0032] 4. The inlet and outlet are diagonally distributed, which makes the circulating water flow from bottom to top through the contact surface of the friction roller and the drive roller, which helps the circulating water to flush away the aluminum scale and impurities removed from the drive roller in a timely manner.

[0033] 5. An external water tank is provided outside the cleaning water tank. The wastewater flowing out of the cleaning water tank outlet first enters the external water tank, and then enters the circulation pipeline through the overflow port, ensuring that there are no impurities left in the tank liquid at the transmission roller and friction roller, effectively reducing the risk of scaling.

[0034] 6. The overflow outlet is higher than the water outlet, meaning the cleaning water tank is submerged below the surface of the water tank, which helps to ensure a stable water volume in the cleaning water tank. Attached Figure Description

Detailed Implementation

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] Specific implementation examples Figure 1-3 As shown, the automatic descaling device for the submerged transmission roller includes a frame 1, on which a horizontal transmission roller 2 is rotatably connected. A friction roller 3 is provided above the transmission roller 2. The friction roller 3 is slidably connected to the frame 1 and is in close contact with the transmission roller 2 by gravity. The transmission roller 2 and the friction roller 3 are submerged below the liquid surface of the cleaning water tank 16, which is connected to the water circulation filtration mechanism 4.

[0041] Specifically, the automatic descaling device of this utility model can be used to remove aluminum scale and prevent scaling on the transmission roller 2 of the submersible transmission. This is mainly achieved through the friction roller 3. The friction roller 3 is pressed against the transmission roller 2 by gravity, which can adapt to different sizes of transmission roller 2 and can also compensate for wear caused by long-term use, ensuring stable contact between the two. At the same time, it has low resistance to the rotation of the transmission roller 2. As the transmission roller 2 rotates, the friction roller 3 scrapes off or disperses the scale impurities on the transmission roller 2, which helps the circulating water in the cleaning water tank 16 to flush away the aluminum scale impurities and clean the transmission roller 2. The water circulation filtration mechanism 4 is used to realize the flow circulation and filtration of water in the cleaning water tank 16. The circulation has pressure, which is conducive to flushing away impurities and filtering out aluminum scale impurities. The filtered clean water re-enters the circulation, saving water resources.

[0042] like Figure 1 , 3As shown, the frame 1 has a vertically extending groove 5 with an open top. A slider 17 is slidably connected in the groove 5, and the two ends of the friction roller 3 are respectively connected to the two sliders 17. The sliders 17 are provided with connecting holes, and the ends of the friction roller 3 are rotatably connected to the connecting holes through bearings, allowing them to rotate freely.

[0043] Specifically, the friction roller 3 is slidably connected to the slide groove 5 via the slider 17. The slide groove 5 extends vertically, allowing the friction roller 3 to move vertically up and down, ensuring the stable and tight contact of the friction roller 3 with the gravity-driven transmission roller 2. The end of the friction roller 3 is rotatably connected to the connecting hole, meaning the friction roller 3 can rotate with the transmission roller 2. This reduces the rotational resistance and wear on the transmission roller 2. The friction roller 3 primarily removes aluminum scale impurities by crushing the sidewall of the transmission roller 2 to disperse the scale, which then helps the circulating water flush it away.

[0044] As an optimization of this embodiment, a gravity drop is detachably connected to the outside of the slider 17. This increases the pressure between the transmission roller 2 and the friction roller 3, ensuring stable contact and engagement between them. Furthermore, the gravity drop is detachably installed via a hook connection, allowing for flexible adjustment of the number of gravity drop bodies to regulate the downward pressure.

[0045] In this embodiment, the friction roller 3 is cylindrical and has a longitudinal corrugated structure 6 on its side wall. The friction roller 3 is rotatably connected to the frame 1.

[0046] Specifically, the friction roller 3 is provided with a longitudinal corrugated structure 6. The corrugations of the longitudinal corrugations extend along the axial direction of the friction roller 3. When the friction roller 3 rolls over the transmission roller 2, the corrugations press against the side wall of the transmission roller 2. With continuous rotation, the aluminum scale on the side wall of the transmission roller 2 is broken down and dispersed, which is conducive to the circulating water washing down and carrying away the aluminum scale impurities.

[0047] like Figure 1 , 2 As shown, the water circulation filtration mechanism 4 includes a water circulation power component 7 and a filter component 8. The cleaning water tank 16 has an inlet 9 and an outlet 10. The inlet 9 is located on the lower part of the side wall of the cleaning water tank 16, and the outlet 10 is located on the upper part of the side wall of the cleaning water tank 16, and is diagonally distributed with respect to the inlet 9. The cleaning water tank 16 is located inside an outer water tank 12, which has an overflow port 13. The cleaning water tank 16 has an outlet 10 and an inlet 9. The overflow port 13 is connected to the inlet 9 via a circulation pipe 11, and the circulation pipe 11 is equipped with the water circulation power component 7 and the filter component 8. The cleaning water tank 16 includes a closed tank body. The top of the tank body is provided with a strip through hole 14 and a frame through hole 15. The strip conveyed on the drive roller 2 passes through the strip through hole 14. The frame 1 passes through the frame through hole 15 and extends into the tank. The water outlet 10 and the water inlet 9 are provided on the side wall of the closed tank body, and the water outlet 10 is higher than the water inlet 9, and the overflow port 13 is higher than the water outlet 10.

[0048] Specifically, the water circulation power assembly 7 provides the power required for water circulation, using a circulating water pump. The inlet 9 on the cleaning water tank 16 is used to input filtered clean water, and the outlet 10 is used to output wastewater that may carry aluminum scale impurities. The filter assembly 8 is used to filter out the aluminum scale impurities in the wastewater, achieving a closed-loop connection and ensuring the cleanliness of the drive roller 2. The inlet 9 and outlet 10 are diagonally distributed, causing the circulating water to flow from bottom to top through the contact surface of the friction roller 3 and the drive roller 2, which helps the circulating water to promptly flush away the aluminum scale impurities removed from the drive roller 2. An outer water tank 12 is provided outside the cleaning water tank 16. The wastewater flowing out of the outlet 10 of the cleaning water tank 16 first enters the outer water tank 12, and then enters the circulation pipeline 11 through the overflow port 13, ensuring that there are no impurities remaining in the tank liquid at the drive roller 2 and friction roller 3, effectively reducing the risk of scaling. The main body of the cleaning water tank 16 is a rectangular closed box, which helps reduce the residue of impurities inside the tank. The strip passage 14 on the box body is adapted to the width and thickness of the conveyor belt, and the shape and size of the frame passage 15 are adapted to the corresponding size of the frame 1, ensuring the conveying of the strip and the installation of the drive roller 2 and friction roller 3 with the frame 1. Of course, the top plate of the box body is removable, which facilitates the initial installation and subsequent maintenance. In addition, since the filtration and strip transmission process will take away a small amount of water, the overflow port 13 is higher than the outlet 10, that is, the cleaning water tank 16 is submerged below the liquid surface of the water tank. This helps to ensure the stability of the water volume in the cleaning water tank 16. The reduction in water loss is reflected in the liquid level of the outer water tank 12, without affecting the water volume in the cleaning water tank 16, thus ensuring the descaling and cleaning effect.

[0049] The specific working principle is as follows: Aluminum foil 18 is fed into the outer water tank 12 via the foil-passing roller 19, passes through the strip through-hole 14 on the cleaning water tank 16, goes around the drive roller 2 from below, and exits upward through another strip through-hole 14. It is then conveyed backward through another foil-passing roller 19 above the outer water tank 12. When the drive roller 2 rotates, the side wall of the friction roller 3 with the longitudinal corrugated structure 6 is rolled over the side wall of the drive roller 2. The texture breaks down the aluminum scale impurities on the drive roller 2. The circulating water flows over and washes away the aluminum scale impurities. Then, it flows out from the outlet 10 into the outer water tank 12. Wastewater that may contain impurities flows out from the overflow outlet 13. After being filtered by the filter assembly 8, it is impacted and fed into the cleaning water tank 16 from the inlet 9. This cycle is repeated.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
