Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil plate cold rolling, in particular to an aluminum foil raw material plate cold rolling device. Background Art

[0002] Aluminum foil raw material cold rolling device is a special equipment used to cold-roll aluminum foil raw material (i.e. aluminum foil raw material that has not been finely processed). The main purpose of this device is to accurately control the shape of aluminum foil raw material through cold rolling process to meet the shape accuracy requirements of subsequent processing or use. The aluminum foil raw material passes between the two rollers of the cold rolling mill, and the rollers apply pressure to the aluminum foil to cause plastic deformation, thereby reducing the thickness and improving the shape of the plate;

[0003] During the cold rolling process of aluminum foil raw materials by rollers, the rollers are affected by some factors (for example, when the pressure on the rollers during operation is uneven or too large, it will cause elastic deformation or plastic deformation of the rollers, and excessive temperature will also cause thermal expansion of the rollers), causing the rollers to shift during the rolling process. At this time, if the staff does not discover the deviation in time, it will not only cause deviations in thickness, width or shape of the rolled aluminum foil, affecting the dimensional accuracy of the product, but also the roller deviation will cause scratches, indentations, ripples and other defects on the surface of the aluminum foil, reducing the surface quality of the product, and the long-term existence of the roller deviation problem will aggravate the wear and damage risks of the rollers and other related equipment, and increase maintenance costs and downtime.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides an aluminum foil raw material plate-shaped cold rolling device, which has the following beneficial effects:

[0019] 1. Through the roller offset detection and early warning, the arc plate can be driven to fit the surface of the cold rolling roller and move back and forth. When the cold rolling roller is offset, the reminder is triggered to work. Not only the arc plate fits tightly with the surface of the cold rolling roller, but also the real-time monitoring of the roller operation status is realized compared with the existing shutdown for roller detection. Once the roller is offset, the reminder is triggered immediately, so that the staff can quickly find and deal with the offset, effectively preventing the deviation of the size and surface quality problems of the aluminum foil after cold rolling caused by the offset. Moreover, the movement changes of the arc plate can detect and warn the offset of the cold rolling roller at an early stage, so as to avoid further expansion of the offset problem, thereby reducing the wear of the equipment, extending the service life of the equipment, reducing maintenance costs and downtime, and the thickness, width and shape of the aluminum foil can be better controlled, reducing the occurrence of scratches, indentations and ripple defects, thereby improving the overall quality of aluminum foil cold rolling.

[0020] 2. Through the meshing between the transmission gear and the linkage gear, the rotation of the cold rolling roller can be converted into the horizontal linear reciprocating motion of the arc plate, which not only ensures that the movement of the arc plate and the cold rolling roller is highly synchronized, so that the arc plate can accurately follow the rotation of the cold rolling roller to achieve effective bonding and monitoring, but also does not require the use of an additional drive source for driving, thereby reducing energy loss and improving energy recycling.

[0021] 3. By removing impurities from the aluminum foil surface, the surface of the aluminum foil raw material can be cleaned before entering the cold rolling roller. Compared with the prior art that needs to adjust the cleaning according to the aluminum foil raw material of different thicknesses, the cleaning plate can always fit the surface of the aluminum foil raw material of different thicknesses, which is not only beneficial to the uniform rolling of the cold rolling roller, improves the surface smoothness and flatness of the aluminum foil, and makes the appearance of the aluminum foil after cold rolling more beautiful, but also the cleaning plate can automatically adjust and maintain a fitting state for aluminum foil raw materials of different thicknesses, thereby ensuring the consistency and stability of the cleaning effect.

[0022] 4. Through the connection column, the material stripping plate can follow the upper moving plate to move back and forth horizontally in contact with the upper end surface of the aluminum foil. It can not only continuously push the impurities generated during the cleaning process away from the surface of the aluminum foil, avoiding the accumulation and re-attachment of impurities, thereby improving the cleaning efficiency, but also timely push away the impurities to reduce the amount of dust generated during the cleaning process, improve the air quality of the working environment, and is beneficial to the health of workers.

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] A cold rolling device for aluminum foil raw material in this embodiment, such as Figure 1 - Figure 8 As shown, it includes a mounting frame 1, and cold rolling rollers 3 are symmetrically arranged inside the mounting frame 1. Both ends of the cold rolling rollers 3 are rotatably connected with lifting blocks 6, and the lifting blocks 6 are vertically slidably connected to the inner wall of the mounting frame 1. Tensioning rollers 2 are arranged on both sides of the cold rolling rollers 3, and the tensioning rollers 2 are rotatably connected to the mounting frame 1. Roller deviation detection and early warning mechanisms are arranged on the cold rolling rollers 3, and the roll deviation detection and early warning mechanisms are used to monitor the positions of the rolls.

[0037] In this embodiment, Figure 3 - Figure 5 As shown, the roller deviation detection and early warning mechanism includes symmetrically arranged telescopic plates 403, the telescopic plates 403 are fixedly connected between the lifting blocks 6 on the same side, the telescopic plates 403 are sleeved on the cold rolling roller 3, and the telescopic plates 403 are symmetrically rotated up and down with reciprocating screws 401 connected, the reciprocating screws 401 are threadedly connected with moving plates 402, and the moving plates 402 are symmetrically penetrated and slidably connected with sliding columns 404, and arc plates 406 are fixedly connected between the sliding columns 404 on the same side, and the arc plates 406 are all attached to the outer surface of the cold rolling roller 3, and the reciprocating screws 401 are fixedly connected with linkage gears 410, and the linkage gears 410 are fixedly connected. 10 is meshedly connected with a transmission gear 411 on one side close to the cold rolling roller 3, and the transmission gears 411 are fixedly connected to the cold rolling roller 3. When the cold rolling roller 3 rotates, the transmission gear 411 and the linkage gear 410 are meshedly connected, which can drive the reciprocating screw rod 401 to rotate between the two telescopic plates 403, so that the movable plate 402 slides back and forth horizontally on the surface of the reciprocating screw rod 401. At this time, the movable plate 402 drives the arc plate 406 to move in contact with the surface of the cold rolling roller 3 through the sliding column 404. When the cold rolling roller 3 is offset, the arc plate 406 is pushed to move upward during the movement of the arc plate 406.

[0038] In this embodiment, Figure 3 As shown, the outer surface of the sliding column 404 is sleeved with a first spring 405 , one end of the first spring 405 is fixedly connected to the side wall of the moving plate 402 , and the other end of the first spring 405 is fixedly connected to the side wall of the arc plate 406 .

[0039] In this embodiment, Figure 3As shown, a reminder 409 is fixedly connected to the side of the movable plate 402 away from the arc plate 406, and the reminder 409 is electrically connected to a power switch 408. The power switch 408 is fixedly installed on the side of the movable plate 402 away from the reminder 409. A push rod 407 is attached to the side of the power switch 408 away from the movable plate 402, and the push rod 407 is fixedly connected to the arc plate 406. When the arc plate 406 drives the push rod 407 to rise, the push rod 407 presses the power switch 408, and the power switch 408 and the reminder 409 are electrically connected, so that the reminder 409 works.

[0040] In the prior art, the rollers may deviate during operation. If the staff fails to find the deviation in time, not only will the rolled aluminum foil have deviations in thickness, width or shape, affecting the dimensional accuracy of the product, but the roller deviation will also cause scratches, indentations, ripples and other defects on the surface of the aluminum foil, reducing the surface quality of the product. In addition, the long-standing roller deviation problem will aggravate the risk of wear and damage to the rollers and other related equipment, increase maintenance costs and downtime. Compared with the prior art, the arc plate 406 can be driven to reciprocate in contact with the surface of the cold rolling roller 3 during the rotation of the cold rolling roller 3, and the reminder 409 can be triggered to work when the cold rolling roller 3 deviates. The close fit with the surface of the cold rolling roller 3 realizes the real-time monitoring of the roller operation status. Once the roller deviates, the reminder 409 is immediately triggered, so that the staff can quickly find and deal with the deviation, effectively preventing the deviation of the aluminum foil size and surface quality problems after cold rolling caused by the deviation. Moreover, the movement change of the arc plate 406 can early detect and warn the deviation of the cold rolling roller 3, thereby avoiding further expansion of the deviation problem, thereby reducing the wear of the equipment, extending the service life of the equipment, reducing maintenance costs and downtime, and the thickness, width and shape of the aluminum foil can be better controlled, reducing the occurrence of scratches, indentations and ripple defects, thereby improving the overall quality of the cold rolling of the aluminum foil;

[0041] Secondly, through the meshing between the transmission gear 411 and the linkage gear 410, the rotation of the cold rolling roller 3 can be converted into the horizontal linear reciprocating motion of the arc plate 406, which not only ensures that the movement of the arc plate 406 and the cold rolling roller 3 remains highly synchronized, so that the arc plate 406 can accurately follow the rotation of the cold rolling roller 3 to achieve effective bonding and monitoring, but also eliminates the need for an additional drive source for driving, thereby reducing energy loss and improving energy recycling.

[0042] In other aspects, this embodiment also provides a mechanism for removing impurities from the surface of the aluminum foil to ensure that the surface of the aluminum foil is clean before cold rolling, such as Figure 2 , Figure 6 - Figure 8As shown, the impurity removal mechanism on the aluminum foil surface includes a limit frame 501, which is fixedly connected to the mounting frame 1. A cleaning plate 502 is symmetrically slidably connected inside the limit frame 501, and the cleaning plate 502 is respectively attached to the upper and lower surfaces of the aluminum foil.

[0043] In this embodiment, Figure 7 As shown, lifting columns 504 are symmetrically fixedly connected to the opposite side of the cleaning plate 502, and the lifting columns 504 are all slidably connected to the limiting frame 501. The lifting columns 504 are fixedly connected to the ends away from the cleaning plate 502 with a disk 505, and a second spring 506 is fixedly connected between the disk 505 and the limiting frame 501. The second spring 506 is sleeved on the outer surface of the lifting columns 504. Through the rebound force of the second spring 506, after the aluminum foil passes through the two cleaning plates 502, the lifting columns 504 can be pulled by the disk 505 to slide into the limiting frame 501, and the cleaning plate 502 is pushed to fit the surface of the aluminum foil.

[0044] In this embodiment, Figure 7 and Figure 8 As shown, a slide rail 503 is fixedly connected to the upper side of one side of the limit frame 501, a slide plate 507 is slidably connected to the inside of the slide rail 503, a material stripping plate 509 is slidably connected to the lower end of the slide plate 507, a fixed column 510 is fixedly connected to the side of the material stripping plate 509 close to the limit frame 501, and the fixed column 510 is horizontally slidably connected to the side wall of the upper cleaning plate 502 at one end away from the material stripping plate 509. When the slide plate 507 slides inside the slide rail 503, it can drive the lower material stripping plate 509 to move synchronously, and the material stripping plate 509 can move synchronously on the slide plate 507 when the cleaning plate 502 moves up and down through the fixed column 510 connected to the side wall.

[0045] In this embodiment, Figure 8 As shown, a connecting column 508 is slidably connected to the top of the slide plate 507, and the connecting column 508 is fixedly connected to the lower end surface of the upper movable plate 402 at one end away from the slide plate 507. When the movable plate 402 reciprocates horizontally, the slide plate 507 can be driven to move synchronously through the arranged connecting column 508, and during the lifting process of the movable plate 402, the connecting column 508 can be pulled to move synchronously on the slide plate 507, so that the movable plate 402 and the slide plate 507 always remain connected.

[0046] Compared with the prior art, the surface of the aluminum foil raw material can be cleaned before entering the cold rolling roller 3, and the cleaning plate 502 can always be attached to the surface of the aluminum foil raw material with different thicknesses, which is not only conducive to the uniform rolling of the cold rolling roller 3, but also improves the surface finish and flatness of the aluminum foil, making the appearance of the aluminum foil after cold rolling more beautiful, and for aluminum foil raw materials with different thicknesses, the cleaning plate 502 can automatically adjust and maintain the attached state, thereby ensuring the consistency and stability of the cleaning effect;

[0047] Secondly, by setting the connecting column 508, the material stripping plate 509 can follow the upper moving plate 402 to move back and forth horizontally in contact with the upper end surface of the aluminum foil, which can not only continuously push the impurities generated during the cleaning process away from the surface of the aluminum foil, avoiding the accumulation and re-attachment of impurities, thereby improving the cleaning efficiency, but also timely push away the impurities to reduce the amount of dust generated during the cleaning process, improve the air quality of the working environment, and is beneficial to the health of workers.

[0048] The working process and principle involved in the overall content of the above embodiment are as follows:

[0049] It should be noted that the cold rolling roller 3 is installed on an output shaft, and the cold rolling roller 3 is driven to rotate by the output shaft. The following offset refers to the change in position of the cold rolling roller 3 relative to the output shaft during the working process.

[0050] When the staff needs to cold-roll the aluminum foil, the staff first passes the aluminum foil under the tension roller 2 close to the side of the limit frame 501, and then passes through the gap between the two cleaning plates 502 inside the limit frame 501. When the aluminum foil passes through the cleaning plates 502, the second spring 506 connected between the disc 505 and the limit frame 501 can pull the lifting column 504 to slide into the limit frame 501, and push the cleaning plate 502 connected to one end of the sliding column 404 away from the disc 505 to always fit the surface of the aluminum foil, thereby ensuring the consistency and stability of the cleaning effect.

[0051] When the cleaning plate 502 slides up and down inside the limiting frame 501 under the influence of the second spring 506 and the thickness of the aluminum foil, the upper cleaning plate 502 will drive the material-diverting plate 509 to slide up and down inside the slider synchronously through the fixed column 510 connected to the horizontal sliding on the side wall, so that the material-diverting plate 509 can always be in contact with the upper end surface of the aluminum foil;

[0052] After the aluminum foil raw material passes through the limiting frame 501, the aluminum foil raw material can be fed between the two cold rolling rollers 3, and the two cold rolling rollers 3 are driven to rotate in opposite directions between the lifting blocks 6 to cold roll the aluminum foil raw material. During the rotation of the cold rolling rollers 3, the connected transmission gear 411 and the linkage gear 410 are meshed and connected, which can drive the reciprocating screw rod 401 to rotate synchronously between the two telescopic plates 403. As the reciprocating screw rod 401 rotates, the moving plate 402 connected to the outer surface of the reciprocating screw rod 401 will synchronously perform horizontal reciprocating motion, and through the sliding column 404 that passes through the sliding connection on the moving plate 402, the arc plate 406 is driven to move in contact with the surface of the cold rolling roller 3. At this time, when the cold rolling roller 3 is offset due to external factors, the arc plate 406 will begin to be affected by the offset during the reciprocating movement. There is always a step of sliding upwards, so when the cold rolling roller 3 deviates in any direction, the push rod 407 will press the power switch 408, and the power switch 408 and the reminder 409 are electrically connected, and the reminder 409 is turned on to work, so that the staff can quickly find and deal with the deviation, effectively preventing the deviation of the aluminum foil size and surface quality problems after cold rolling caused by the deviation, and the movement change of the arc plate 406 can early detect and warn the deviation of the cold rolling roller 3, so as to avoid further expansion of the deviation problem, thereby reducing the wear of the equipment, extending the service life of the equipment, reducing maintenance costs and downtime, and the thickness, width and shape of the aluminum foil can be better controlled, reducing the occurrence of scratches, indentations and ripple defects, thereby improving the overall quality of cold rolling of the aluminum foil;

[0053] When the upper moving plate 402 moves horizontally back and forth on the surface of the reciprocating screw rod 401, the moving plate 402 will move the slide plate 507 to slide synchronously back and forth inside the slide rail 503 through the connecting column 508, and drive the material-pickup plate 509 connected to the lower end of the slide plate 507 to move back and forth along the surface of the aluminum foil raw material, which can not only continuously push the impurities generated during the cleaning process away from the aluminum foil surface, avoiding the accumulation and re-attachment of impurities, thereby improving the cleaning efficiency, but also timely pushing away impurities reduces the amount of dust generated during the cleaning process, improves the air quality of the working environment, and is beneficial to the health of workers;

[0054] When the staff needs to adjust the distance between the two cold rolling rollers 3, the existing technology, such as a cylinder, can be used to control the lifting block 6 to slide up and down in the mounting frame 1, so as to drive the two cold rolling rollers 3 to slide closer to and away from each other. When the lifting block 6 moves, the telescopic plate 403 can drive the reciprocating screw rod 401 to move synchronously, so that the arc plate 406 can always fit the surface of the cold rolling roller 3. Moreover, when the reciprocating screw rod 401 moves up and down to drive the movable plate 402 to rise and fall synchronously, the movable plate 402 will pull the connecting column 508 to slide up and down synchronously inside the slide plate 507, so that the movable plate 402 can continue to drive the slide plate 507 to slide inside the slide rail 503 during the subsequent horizontal reciprocating movement.

[0055] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
