A coating production line for aluminum foil production and processing

Abstract

The present invention discloses a coating production line for the production and processing of aluminum foil, comprising the following processing steps: 1) unwinding and feeding, wherein a feeding unit feeds the material at a preset unwinding speed; 2) acid degreasing, wherein the feeding unit feeds the aluminum foil substrate into the degreasing unit for degreasing. The present invention adopts a reel designed on the "rewinding side" of the production line that can detect the material position in real time and perform closed-loop deviation correction in real time. The reel also has an automatic adaptive adjustment function that can adapt to changes in the roll size. As the aluminum foil is conveyed, the aluminum foil can be corrected by itself, and the aluminum foil can be pulled back to the original path from the offset state through "active interference". Moreover, as the roll diameter continues to increase, the reel roller can also move by itself to expand the reeling space, so that the roll can still be normally rewound when the user is not paying attention and the roll diameter continues to increase, and the normal operation of the production line will not be affected.

Description

Technical Field

[0001] The invention relates to the technical field of aluminum foil coating processing, in particular to a coating production line for aluminum foil production and processing. Background Art

[0002] Aluminum foil (aluminum foil board) is mostly used for the surface decoration of boards. For example, setting a layer of aluminum foil (aluminum foil board) on the outer surface of the decorative board can improve the application performance of the decorative board. Wrapping the treated aluminum foil on the surface of the decorative board according to needs can make the decorative board flame retardant, good sealing, leakage-proof and beautiful.

[0003] Such aluminum foil needs to be processed on the production line. The existing aluminum foil coating production line is prone to the following defects:

[0004] 1. It is difficult to achieve real-time deviation correction. The unwinding and winding process of aluminum foil on the production line can be roughly divided into three stages: unwinding and coating, drying and film forming, and cooling and winding. In the winding stage, it is difficult for the production line to correct the deviation of the aluminum foil. As the roller is transported, the aluminum foil is prone to deviation and touches the inner wall of the machine, causing the aluminum foil to wrinkle or even break. Its surface coating layer will also be damaged, reducing the actual performance of the aluminum foil, and will also produce defective products and increase cost investment. For example, a reflective and breathable sunshade cloth production line for windows with application number CN201510630644.3, from the attached figure, it can be preliminarily known that this type of production line only has a relatively simplified processing process of unwinding and coating, cooling and winding, and its technical solution does not specify the correction work when the product is wound. Therefore, the products obtained by such a production line have a high defective rate.

[0005] Second, it is difficult to automatically adapt to changes in the size of the roll. During the process of reeling the aluminum foil, the size of the roll will become larger and larger, and there are generally auxiliary rollers near the reeling rollers. Therefore, if the staff "inattentively" keeps "letting" the aluminum foil continue to reel, the roll will eventually touch the auxiliary rollers, and then be squeezed by the auxiliary rollers, causing the aluminum foil to be severely damaged and deformed. It may even affect the normal operation of the entire production line, reducing the safety of the user's work. For example, a special paper processing production line with application number CN202010941656.9, the production process of the entire production line can be understood from the drawings and instructions, but there is no "reeling end" that can automatically adapt to changes in the roll during the reeling stage. Therefore, such a production line is prone to the situation where the staff is "inattentive" and the roll size continues to increase, and the aluminum foil is squeezed by other rollers, causing damage and deformation, which is also likely to affect the normal operation of the entire production line.

[0006] In view of the above problems, the present invention makes improvements. Summary of the Invention

[0021] In summary, the beneficial effects of the present invention are:

[0022] 1. The present invention adopts a winder designed on the "winding side" of the production line that can detect the material position in real time and perform closed-loop correction in real time. The winder also has the function of automatically adapting to changes in roll size. In this way, when the winder winds up aluminum foil, it can automatically correct the aluminum foil as the aluminum foil is conveyed. Through "active interference", the aluminum foil is pulled back to the original path from the offset state, preventing it from touching the inner wall of the machine and wrinkling and damage during the winding process. In addition, as the roll diameter continues to increase, the winding roller can also move automatically to expand the winding space, so that the roll can still be wound normally even when the user is not paying attention and the roll diameter continues to increase, and it will not affect the normal operation of the production line.

[0023] The present invention provides a first correction mechanism, and when the aluminum foil passes between the lower correction roller and the two lower correction rollers, a traction force is applied to the lower correction roller and the lower correction roller, so that the lower correction roller and the lower correction roller will rotate accordingly, and the setting of the lower correction roller is angled. Since the axis of the lower correction roller is inclined to the traction direction, the rotation of the two will provide lateral pulling force for the aluminum foil, thereby correcting the deviated aluminum foil. The user can also control the cylinder to work, and then the cylinder drives the connecting plate to move up and down, and the sliding sleeve welded on the connecting plate will also move accordingly. At the same time, the sliding sleeve will slide on the guide block, so that the lower correction roller can be adjusted up and down, and the user can make appropriate adjustments according to the processing thickness of the aluminum foil to ensure that the lower correction roller and the upper correction roller can press the aluminum foil without affecting the transportation of the aluminum foil, thereby preventing the lower correction roller and the upper correction roller from idling and improving the correction effect.

[0024] 3. The present invention is provided with a coating machine, and cylinders are installed at both ends of the coating roller 2 and the coating roller 1. In this way, the coating roller 2 and the coating roller 1 can be pushed to move under the action of the cylinder, and the distance between the coating roller 2 and the coating roller 1 and the coating roller 4 will be expanded. The user will have enough space when replacing the coating roller 3, and can smoothly place the coating roller 3 to the appropriate position according to the processing requirements to complete the replacement of the coating roller 3, which is convenient to operate, saves time and effort, and is highly efficient. Semicircular fixings are provided at both ends of the coating roller 3, and the two semicircular fixings can form a complete fixing and are fixed together with bolts. One of the semicircular fixings is fixed on the fixing frame 2, and the other semicircular fixing can be flexibly removed. In this way, the required rollers, such as steel rollers or rubber rollers, can be replaced according to actual processing requirements, providing more selectivity for the coating processing of aluminum foil and improving the coating quality of aluminum foil.

[0025] 4. The present invention is provided with a driving traction machine. When in use, the two cylinders 2 are turned on to drive the two sliding blocks to move up and down inside the sliding frame. In this way, the pressure roller will follow the up and down movement, and the distance between the pressure roller and the traction roller above can be adjusted. In this way, the pressure roller can cooperate with the corresponding traction roller to press the aluminum foil according to actual needs without affecting the transportation of the aluminum foil, so as to prevent the aluminum foil from loosening and shrinking, causing machine blockage and damage to the equipment.

[0026] The present invention provides a reel that is movable and adjustable, and as the reel moves, the distance between the reel and other rollers on the machine will gradually widen, leaving enough space for the aluminum foil to continue to be reeled, until an alarm is issued to prompt the user to handle it. In this way, the aluminum foil will not be squeezed and damaged due to the continuous expansion of the bundle during the reeling process, and the normal operation of the machine will be avoided. Sufficient time is reserved for the user to handle emergencies, thereby reducing the occurrence of accidents and improving work safety and efficiency. At the same time, gear 2 and gear 1 are connected by chain transmission, and the two chains are fixed on the reel, and then the gears 2 on both sides rotate synchronously through the synchronous shaft rod. In this way, under the action of the chain and the synchronous shaft rod, the two gears 2 and the two gears 1 will rotate synchronously. In this way, driven by the two chains, the two ends of the reel can realize synchronous movement, thereby ensuring the regularity of the aluminum foil reeling.

[0027] 6. The present invention sets a second deviation correction mechanism. During the aluminum foil rolling process, when the machine deviates, the stepper motor will be started through real-time monitoring by the sensor, and then the stepper motor will drive the threaded rod to rotate, and the stepper motor will drive the two sides of the threaded sleeve to move, and the threaded sleeve will drive the two sides of the base frame to move. In this way, the entire winder will also follow the movement to perform deviation correction adjustments to prevent the aluminum foil from being damaged due to deviation during rolling. When the base frame moves, it will drive four limit sliders to slide on four limit guide rails respectively, so as to limit the base frame and ensure the stability of the base frame when sliding.

[0040] refer to Figure 1A coating production line for the production and processing of aluminum foil includes the following processing steps: 1) unwinding and feeding, the feeding unit feeds the material at a preset feeding speed; 2) acid degreasing, the feeding unit feeds the aluminum foil substrate into the degreasing unit for degreasing, the aluminum foil substrate passes through the degreasing liquid, and the degreasing liquid must cover the surface of the substrate; 3) substrate cleaning, after the aluminum foil substrate is sent out from the degreasing unit, it passes through the cleaning unit to remove the residual stains on the surface; 4) paint film coating, the cleaned aluminum foil substrate passes through the coating The unit performs surface coating operations on its surface. The coating unit is pre-activated and begins coating the substrate with paint liquid when it is fed in. 5) Drying: The aluminum foil substrate passes through the conveyor mechanism of the baking unit to be dried in an oven. 6) Cooling: The dried aluminum foil is cooled by the air cooling unit. 7) Deflection angle correction: The aluminum foil with the surface paint liquid cooled and formed into a paint film is corrected and adjusted by the correction unit. 8) Reeling: The reeling traction unit pulls the aluminum foil out of the air cooling unit and reels it into bundles (rolls) through the reeling unit.

[0041] A feeding unit 2 is added between the paint film coating step 4) and the substrate cleaning step 3). The aluminum foil substrate that does not need to be degreased can be directly fed through the current feeding unit for direct coating;

[0044] The specific use process is as follows: the unprocessed aluminum foil is placed on the unwinder 7, and then the unwinder 7 unwinds and feeds the aluminum foil. The aluminum foil is sent to the coating machine 6 for coating, that is, a layer of paint film is coated on the surface of the aluminum foil to improve the performance of the aluminum foil. The aluminum foil coated with the paint film passes through the coating machine 6 and enters the main oven 4 for drying. It should be noted that a number of conveying rollers are set in the main oven 4 for conveying the aluminum foil. When conveying the aluminum foil, the side coated with the paint film faces upward. A heating device is installed on the top of the inner cavity of the main oven 4 to utilize the heat of the aluminum foil to heat the aluminum foil. The paint liquid is solidified at high temperature on the aluminum foil to form a paint film. The aluminum foil passes through the main oven 4 and enters the air cooling box 3 after coming out of the main oven 4. The air cooling box 3 cools the aluminum foil. After cooling, it passes through the correction mechanism 2 and then passes through the driving traction machine 8 and is finally rolled into a bundle by the winder 9.

[0046] Specifically, when the aluminum foil passes between the lower correcting roller 22 and the two lower correcting rollers 27, a traction force is applied to the lower correcting roller 22 and the lower correcting roller 27, so that the lower correcting roller 22 and the lower correcting roller 27 will rotate accordingly, and the setting of the lower correcting roller 27 is at an angle. Since the axis of the lower correcting roller 27 is inclined to the traction direction, it should be noted that the rotation of the two will provide lateral pulling force for the aluminum foil, thereby correcting the deviated aluminum foil.

When the aluminum foil is rolled to a certain size, the user cuts the aluminum foil and removes the current roll, and then continues to roll. This is a prior art and will not be explained in detail in the article. At the same time, the change of the aluminum foil roll will be monitored in real time through the sensor. When the user is not paying attention and the size of the aluminum foil exceeds the set size and continues to roll, the sensor detects the change of the roll and then uploads the instruction to the central processor. The central processor then controls the cylinder three 96 to start working and push the winding roller 95 to move away from the driving traction machine 8. As the winding roller 95 moves, it and the machine The spacing between the other rollers will gradually open up, leaving enough space for the aluminum foil to continue to be rolled up, until finally an alarm is issued to prompt the user to handle it. In this way, the aluminum foil will not be squeezed and damaged during the rolling process because the bundle continues to grow larger, and the normal operation of the machine is avoided. Sufficient time is reserved for the user to handle emergencies, reducing the occurrence of accidents and improving work safety and efficiency. At the same time, gear 2 93 and gear 1 92 are connected by a chain 94 transmission. The two chains 94 are fixed on the winding roller 95, and then the gears 2 93 on both sides rotate synchronously through the synchronization shaft 99. In this way, under the action of the chain 94 and the synchronization shaft 99, the two gears 2 93 and the two gears 1 92 will rotate synchronously. In this way, driven by the two chains 94, the two ends of the winding roller 95 can move synchronously to ensure the regularity of the aluminum foil rolling.

[0051] The driving traction machine 8 includes two fixed frames 3 81 fixedly installed on one side of the top of the base frame 910, two traction rollers 82 are rotatably installed at the bottom between the two fixed frames 3 81, and a pressure roller 85 is provided at the top between the two fixed frames 3 81. A sliding frame 83 is embedded and fixedly installed on the top of the fixed frame 3 81, and a sliding block 86 is installed inside the sliding frame 83 for sliding up and down. The two sliding blocks 86 are respectively sleeved on the two ends of the pressure roller 85, and a cylinder 2 84 is fixedly installed on the top of the sliding frame 83. The output end of the cylinder 2 84 passes through the interior of the sliding frame 83 and is fixedly connected to the sliding block 86.

[0052] Specifically, when the aluminum foil comes out of the correction mechanism 2 and enters the driving traction machine 8, the two cylinders 2 84 are turned on and the two sliding blocks 86 can be driven by the cylinder 2 84 to move up and down inside the sliding frame 83, so that the pressure roller 85 will follow the up and down movement, and then the distance between the pressure roller 85 and the upper traction roller 82 can be adjusted. In this way, the pressure roller 85 can cooperate with the corresponding traction roller 82 to press the aluminum foil according to actual needs without affecting the transportation of the aluminum foil, so as to prevent the aluminum foil from loosening and shrinking, causing the machine to be blocked, resulting in damage to the equipment. It should be noted that a drive device motor can be installed on the outside of any fixed frame 3 81, and connected to the two traction rollers 82, thereby driving the two traction rollers 82 to rotate, so that when the traction roller 82 rotates, the aluminum foil can be sent out, thereby realizing active traction. This is a prior art and will not be explained in detail in this article.

[0053] The correcting mechanism 2 16 includes a base 161 set on the ground, four limiting guide rails 167 are fixedly installed on the top of the base 161, and a limiting slider 168 is slidably installed on the top of the limiting guide rail 167. The top of the limiting slider 168 is fixedly connected to the base 910. Two supporting plates 162 are welded to one side of the base 161, and a cross plate 169 is fixedly installed on the top of the two supporting plates 162. Two screw racks 164 are fixedly installed on the top of the cross plate 169, and a threaded rod 166 is rotatably installed between the two screw racks 164. One end of the threaded rod 166 is fixedly installed with a stepping motor 163, and the stepping motor 163 is fixedly installed on the cross plate 169. A threaded sleeve 165 is threadedly installed on the surface of the threaded rod 166, and one side of the threaded sleeve 165 is fixedly installed on the base 910.

[0054] Specifically, during the process of winding the aluminum foil, when the machine deviates, the stepper motor 163 will be started through real-time monitoring by the sensor. This is a prior art and will not be explained in detail in this article. Then the stepper motor 163 will drive the threaded rod 166 to rotate, and the stepper motor 163 will drive the threaded sleeve 165 to move on both sides, and the threaded sleeve 165 will drive the base frame 910 to move on both sides. In this way, the entire winding machine 9 will also follow the movement to perform correction adjustments to prevent the aluminum foil from being damaged due to deviation during winding. When moving, the base frame 910 will drive the four limit sliders 168 to slide on the four limit guide rails 167 respectively, so as to limit the base frame 910 and ensure the stability of the base frame 910 when sliding.

[0055] The winder is designed on the "winding side" of the production line and can detect the material position in real time and perform closed-loop correction in real time. The winder also has the function of automatically adapting to changes in roll size. In this way, when the winder winds up aluminum foil, it can automatically correct the aluminum foil as it is conveyed. Through "active interference", the aluminum foil is pulled back to the original path from the offset state to prevent it from touching the inner wall of the machine and wrinkling and damage during the winding process. As the roll diameter continues to increase, the winding roller can also move automatically to expand the winding space, so that the roll can still be wound normally when the user is not paying attention and the roll diameter continues to increase, and it will not affect the normal operation of the production line.

[0056] Example 2:

[0057] refer to Figure 1 A coating production line for the production and processing of aluminum foil includes the following processing steps: 1) unwinding and feeding, the feeding unit feeds the material at a preset feeding speed; 2) acid degreasing, the feeding unit feeds the aluminum foil substrate into the degreasing unit for degreasing, the aluminum foil substrate passes through the degreasing liquid, and the degreasing liquid must cover the surface of the substrate; 3) substrate cleaning, after the aluminum foil substrate is sent out from the degreasing unit, it passes through the cleaning unit to remove the residual stains on the surface; 4) paint film coating, the cleaned aluminum foil substrate passes through the coating The unit performs surface coating operations on its surface. The coating unit is pre-activated and begins coating the substrate with paint liquid when it is fed in. 5) Drying: The aluminum foil substrate passes through the conveyor mechanism of the baking unit to be dried in an oven. 6) Cooling: The dried aluminum foil is cooled by the air cooling unit. 7) Deflection angle correction: The aluminum foil with the surface paint liquid cooled and formed into a paint film is corrected and adjusted by the correction unit. 8) Reeling: The reeling traction unit pulls the aluminum foil out of the air cooling unit and reels it into bundles (rolls) through the reeling unit.

[0058] A feeding unit 2 is added between the paint film coating step 4) and the substrate cleaning step 3). The aluminum foil substrate that does not need to be degreased can be directly fed through the current feeding unit for direct coating;

[0059] Step 3) The substrate cleaning process includes: a water squeezing mechanism and a water drying mechanism. The water squeezing mechanism is arranged before the water drying mechanism, and the heating end of the drying mechanism is directed toward the aluminum foil substrate to dry the aluminum foil substrate.

[0060] The coating production line also includes an installation platform 1, a correction unit, an air cooling unit, and a baking unit arranged on the top of the installation platform 1 from left to right, a feeding unit 1, a degreasing unit, and a cleaning unit arranged on the bottom of the installation platform 1 from left to right, a feeding unit 2 and a coating unit arranged on the right side of the installation platform 1 from left to right, a winding unit and a material receiving traction unit arranged on the left side of the installation platform 1 from left to right, the correction unit includes a correction mechanism 1 2 and a correction mechanism 2 16, the correction mechanism 1 2 is fixedly installed on the installation platform 1, the correction mechanism 2 16 is arranged on the ground, the air cooling unit includes an air cooling box 3 fixedly installed on the installation platform 1, the baking unit includes a main oven 4 fixedly installed on the installation platform 1, the feeding unit 1 includes an uncoiler 1 7 arranged on the ground, the coating unit The invention comprises a coating machine 6 arranged on the ground, a winding unit comprising a winding machine 9, the second correction mechanism 16 is fixedly installed at the bottom of the winding machine 9, the material receiving traction unit comprises a driving traction machine (8) fixedly installed on the winding machine (9), the degreasing unit comprises an acid degreasing tank 12 arranged on the ground and a sheet splicing platform 11 arranged on the ground and located on the left side of the acid degreasing tank 12, the second feeding unit comprises a second uncoiler 10 arranged on the ground, the cleaning unit comprises a clean water spraying tank 14 arranged on the ground and a water drying tank 15 arranged on the ground and located on the right side of the clean water spraying tank 14, a water squeezing roller group 13 is fixedly installed above the inner side of the clean water spraying tank 14, and it should be noted that the water squeezing mechanism in step 3) is the water squeezing roller group 13, and the water drying mechanism is the water drying tank 15.

[0061] The specific use process is as follows: the unprocessed aluminum foil paper bundle is placed on the unwinding machine 10, and then the unwinding machine 10 unwinds and feeds the aluminum foil paper to the splicing platform 11, and then enters the acid degreasing tank 12 through the splicing platform 11. It should be noted that the acid degreasing tank 12 is provided with a number of rollers. Under the action of these rollers, the aluminum foil paper will be degreased from the "acid degreasing liquid" in the acid degreasing tank 12, so as to improve the quality of the aluminum foil paper and facilitate the subsequent During the coating of the paint liquid, the paint liquid is ensured to be "firmly" attached to the aluminum foil. After the aluminum foil comes out of the acid degreasing tank 12, it enters the clean water spray tank 14 for clean water spraying to remove excess degreasing liquid. When passing through the clean water spray tank 14, it also passes through the squeezing roller group 13. Because the squeezing roller group 13 is arranged above the clean water spray tank 14, the excess water is squeezed out under the action of the squeezing roller group 13, and then sent out to the water drying tank 15 to dry the excess water, and then Then it is sent to the coating machine 6 for coating, that is, a layer of paint film is coated on the surface of the aluminum foil to improve the performance of the aluminum foil. The aluminum foil coated with the paint film passes through the coating machine 6 and enters the main oven 4 for drying. It should be noted that a number of conveying rollers are set in the main oven 4 for conveying the aluminum foil. When conveying the aluminum foil, the side coated with the paint film faces upward. A heating device is installed on the top of the inner cavity of the main oven 4. The high temperature is used to solidify the paint liquid on the aluminum foil to form a paint film. After passing through the main oven 4 and coming out of the main oven 4, the foil enters the air cooling box 3, where it is cooled down. After cooling, the foil passes through the correction mechanism 2, and then passes through the driving traction machine 8 and is finally rolled into a bundle by the winder 9. The correction mechanism 2 can correct the deviation to ensure the regularity of the aluminum foil rolling, and the driving traction machine 8 can play a traction role. While conveying the aluminum foil web to the winder 9, it can also press the aluminum foil to prevent the aluminum foil from loosening and shrinking.

[0062] In this way, the aluminum foil is degreased before coating to remove surface impurities, and then cleaned and dried, which greatly ensures the cleanliness of the aluminum foil surface. Then, when coating, the paint liquid can perfectly combine with the aluminum foil to form a paint film on its surface, thereby improving the production and processing quality and performance of the aluminum foil.

[0063] It should be noted that the functions to be implemented by the hardware in the present invention are supported by a large number of mature technologies and belong to the existing technology. The essence of the present invention is to optimize the combination of existing hardware and its connection methods for specific application scenarios to meet the adaptation needs in specific application scenarios, and solve the problems raised in the background technology without involving improvements to the internal software of the hardware.

[0064] Example 3:

[0065] based on Figure 1 ,refer to Figure 5-8The correcting mechanism 2 includes two fixed frames 21 fixedly mounted on the mounting platform 1, a lower correcting roller 22 is rotatably mounted between the two fixed frames 21, a guide block 23 is welded on the inner side of the fixed frame 21, a sliding sleeve 24 is slidably mounted on the surface of the guide block 23, a connecting plate 25 is welded on one side of the sliding sleeve 24, two rotating shaft frames 26 are fixedly mounted on the inner side of the connecting plate 25, a lower correcting roller 27 is arranged between the two rotating shaft frames 26, one end of the lower correcting roller 27 is rotatably mounted on two of the rotating shaft frames 26 through a bearing, a cylinder 28 is fixedly mounted on the top of the fixed frame 21, the output end of the cylinder 28 passes through the inner side of the fixed frame 21 and is fixedly mounted on the top of the connecting plate 25, a buffer 29 is fixedly mounted on the bottom of the inner side of the fixed frame 21, The correcting mechanism 16 includes a base 161 set on the ground, and four limiting guide rails 167 are fixedly installed on the top of the base 161. A limiting slider 168 is slidably installed on the top of the limiting guide rail 167. The top of the limiting slider 168 is fixedly connected to the base 910. Two support plates 162 are welded on one side of the base 161, and a cross plate 169 is fixedly installed on the top of the two support plates 162. Two screw racks 164 are fixedly installed on the top of the cross plate 169. A threaded rod 166 is rotatably installed between the two screw racks 164. A stepping motor 163 is fixedly installed on one end of the threaded rod 166, and the stepping motor 163 is fixedly installed on the cross plate 169. A threaded sleeve 165 is threadedly installed on the surface of the threaded rod 166, and one side of the threaded sleeve 165 is fixedly installed on the base 910.

[0066] Specifically, when the aluminum foil passes between the lower correcting roller 22 and the two lower correcting rollers 27, a traction force is applied to the lower correcting roller 22 and the lower correcting roller 27, so that the lower correcting roller 22 and the lower correcting roller 27 will rotate accordingly, and the setting of the lower correcting roller 27 is angled. Since the axis of the lower correcting roller 27 is inclined to the traction direction, it should be noted that the rotation of the two will provide lateral pulling force for the aluminum foil, thereby correcting the deviated aluminum foil. It should be noted that the inclination direction of the lower correcting roller 27 is set according to actual needs, that is, an oblique texture can be set on the surface of the lower correcting roller 27. The overall shape of the lower deflection-correcting roller 27 can be set to be oblique, and the user can set it according to actual needs. The user can also control the cylinder 1 28 to work, and then the cylinder 1 28 drives the connecting plate 25 to move up and down, and the sliding sleeve 24 welded on the connecting plate 25 will also move accordingly. At the same time, the sliding sleeve 24 will slide on the guide block 23, so that the lower deflection-correcting roller 27 can be adjusted up and down. The user can make appropriate adjustments according to the processing thickness of the aluminum foil to ensure that the lower deflection-correcting roller 22 and the lower deflection-correcting roller 27 do not affect the transportation of the aluminum foil, and can press the aluminum foil tightly to prevent the lower deflection-correcting roller 22 and The lower correction roller 27 is idle, and the correction effect is improved. During the aluminum foil winding process, when the machine deviates, the stepper motor 163 will be started through real-time monitoring by the sensor. This is a prior art and will not be described in detail in the text. Then the stepper motor 163 will drive the threaded rod 166 to rotate, and the stepper motor 163 will drive the threaded sleeve 165 to move on both sides, and the threaded sleeve 165 will drive the chassis 910 to move on both sides. In this way, the entire winding machine 9 will also follow the movement to perform correction adjustment to prevent the aluminum foil from being damaged due to deviation during winding. The chassis 910 will drive four limit sliders 168 when moving. It slides on the four limiting guide rails 167 respectively to limit the base frame 910 and ensure the stability of the base frame 910 when sliding. In summary, the correction adjustment is performed simultaneously at the entry end and the tail end of the aluminum foil paper rolling, and the aluminum foil paper can be quickly pulled back to the original rail when it deviates, so as to ensure the quality of the aluminum foil paper after rolling. In addition, the correction adjustment of the aluminum foil paper body is performed through the correction mechanism 1 2, and the correction adjustment of the winding body is also performed through the correction mechanism 2 16. In this way, the offset angle of the aluminum foil paper is adjusted simultaneously from two directions using two methods, which can greatly improve the correction accuracy.

[0067] It should be noted that all electrical equipment on the production line has a central control device or terminal control. This is existing technology and will not be explained in detail in this article.
