Description

[0002] Calendering is a metalworking process that thins, flattens or changes the shape of a metal sheet by passing it between one or more pairs of rotating rollers and applying pressure. For the production of aluminum foil, multiple rounds of calendering are usually required to gradually reach the required thickness.

[0003] During the calendering process of aluminum foil, special attention must be paid to the surface quality.

[0020] The motion assembly includes a fixed frame 3, a driving member 4, a connecting frame 5, a servo motor 6 and a rotating shaft 7; a fixed frame 3 is arranged between two conveyor belts 1; a plurality of driving members 4 symmetrical in upper and lower directions are fixedly connected to the fixed frame 3, and the driving members 4 are electric push rods; the telescopic ends of the driving members 4 located on the same side are commonly fixedly connected to a connecting frame 5; a servo motor 6 is fixedly connected to the front side of each connecting frame 5; a rotating shaft 7 is fixedly connected to the output end of each servo motor 6; each rotating shaft 7 is rotatably connected to an adjacent connecting frame 5; and each rotating shaft 7 is fixedly connected to an adjacent pressure roller 8.

[0021] The oil delivery assembly includes an oil delivery pipe 101 and an oil storage tank 102; an oil delivery pipe 101 is connected to the rear side of each rotating shaft 7; a pressure pump is arranged on each oil delivery pipe 101; an oil storage tank 102 is fixedly connected to the lower side of the fixed frame 3; one end of each oil delivery pipe 101 away from the rotating shaft 7 is fixedly connected to and connected with the oil storage tank 102; each rotating shaft 7 is configured as a hollow structure; a plurality of first through holes 7001 distributed in an annular shape are provided on each rotating shaft 7; a plurality of second through holes 8001 distributed in an annular shape are provided on each pressure roller 8; each second through hole 8001 corresponds one-to-one to an adjacent first through hole 7001; an oil storage cavity 8002 is provided on each pressure roller 8; each oil storage cavity 8002 is connected to an adjacent second through hole 8001; each oil storage cavity 8002 is connected to an adjacent connecting pipe 9.

[0022] It also includes a flattening roller 103 ; two flattening rollers 103 symmetrically connected to the conveyor belt 1 on the right side are rotatably connected, and the rolled aluminum foil 2 passes through the position between the two flattening rollers 103 .

[0023] First, the aluminum foil 2 is transported from left to right by the conveyor belt 1 on the left, so that the aluminum foil 2 gradually approaches the position between the upper and lower pressure rollers 8. Then, based on the view from front to back, the servo motor 6 on the upper side is controlled to drive the rotating shaft 7 to rotate counterclockwise, thereby driving the pressure roller 8, the connecting tube 9 and the extrusion plate 10 on the upper side to rotate counterclockwise, and then driving the elastic member 11 and the rolling plate 12 on the upper side to rotate counterclockwise. Similarly, the servo motor 6 on the lower side drives the elastic member 11 and the rolling plate 12 on the lower side to rotate clockwise, so that when the aluminum foil 2 passes between the upper and lower pressure rollers 8, it first contacts with the rolling plate 12. If there is a raised portion 2003 on the surface of the aluminum foil 2, when it passes through the upper and lower pressure rollers 8, When the rolling plate 12 is between the pressing rollers 8, these protrusions 2003 may be folded with the surrounding materials due to the oblique pressure, causing defects, which will not only affect the appearance of the aluminum foil 2, but also may reduce its physical properties and use effect. For the convenience of description, the following takes the components located on the upper side of the aluminum foil 2 as an example. When the rolling plate 12 follows the pressing roller 8 to rotate counterclockwise and contact the aluminum foil 2, it will also contact the protrusions 2003 on the aluminum foil 2, so that the rolling plate 12 and the extrusion part 2001 are squeezed against each other. At this time, the rolling plate 12 is squeezed by the protrusions 2003, which compresses the elastic member 11 and moves the rolling plate 12 toward the pressing roller 8. At the same time, the protrusions 2003 are squeezed by the rolling plate 12 and slightly deformed. Then, When the rolling plate 12 continues to rotate to the position directly below the pressure roller 8, the rolling plate 12 contacts the pressure roller 8 and is limited by the pressure roller 8 and cannot move further, so that the rolling plate 12 directly below the pressure roller 8 rolls the aluminum foil 2 and the raised portion 2003 on the aluminum foil 2, causing the aluminum foil 2 to deform and gradually become thinner, and then gradually passes through the position between the upper and lower rolling plates 12, thereby achieving the rolling of the aluminum foil 2. In the above process, the raised portion 2003 is not directly squeezed hard, but elastically squeezed, and as the compression degree of the elastic member 11 increases, the extrusion force on the raised portion 2003 gradually increases. In this process, the deformation trend of the raised portion 2003 is its bulge degree. It gradually becomes smaller, and when passing the position directly below the pressure roller 8, the raised part 2003 with a greatly reduced degree of protrusion will be hard squeezed by the rolling plate 12. In this way, the raised part 2003 will not be squeezed and folded with the surrounding materials, thereby ensuring the physical properties and use effect of the aluminum foil 2; then the rolling plate 12 continues to rotate, so that the rolling plate 12 that has just contacted the aluminum foil 2 is away from directly below the pressure roller 8, so that the elastic member 11 gradually returns to its original state, and the rolling plate 12 gradually returns to its initial state, and through the friction between the upper and lower rolling plates 12 and the aluminum foil 2, the aluminum foil 2 is driven to move to the right to the conveyor belt 1 on the right, and then the aluminum foil 2 with a thinned thickness is transmitted to the next process through the conveyor belt 1 on the right.

[0024] Taking into account that the above-mentioned rolling method of the aluminum foil 2 by the sliding rolling plate 12 will cause intermittent vertical lines to appear on the surface of the aluminum foil 2, affecting the flatness of the surface of the aluminum foil 2, therefore, when the aluminum foil 2 moves to the right under the transmission of the conveyor belt 1 located on the right, the vertical lines on the aluminum foil 2 are thoroughly rolled by two flattening rollers 103 to keep the surface of the aluminum foil 2 flat, thereby improving the product quality of the aluminum foil 2.

[0025] At the same time, the lubricating oil in the oil storage tank 102 is pumped into the oil delivery pipe 101 through the pressure pump on the oil delivery pipe 101, and then enters the rotating shaft 7 along the oil delivery pipe 101, and then enters the oil storage chamber 8002 from the first through hole 7001 and the second through hole 8001. The centrifugal force generated by the rotation of the rotating shaft 7 and the pressure roller 8 causes the lubricating oil in the oil storage chamber 8002 to enter the cavity of the rolling plate 12 along the connecting pipe 9. Since the cavity in the rolling plate 12 is divided into an air intake space and an oil outlet space by the extrusion plate 10, the lubricating oil entering the cavity of the rolling plate 12 will enter the oil outlet space. It should be noted that, since the lubricating oil has a certain viscosity and tension, and the cross-section of the oil outlet groove 12002 is small, the lubricating oil in the oil outlet space is difficult to flow out from the oil outlet groove 12002 under the action of the centrifugal force generated by the rotation of the rolling plate 12. Then, since the positions of the connecting pipe 9 and the extrusion plate 10 remain unchanged, and the extrusion plate 10 divides the inside of the rolling plate 12 into an air intake space and an oil outlet space, the volume of the air intake space will gradually increase during the movement of the rolling plate 12 toward the center of the pressure roller 8, so that the external space will enter the air intake space through the air hole 12001. , and the volume of the oil outlet space will gradually decrease, so that the lubricating oil in the oil outlet space is squeezed and sprayed along the oil outlet groove 12002 onto the aluminum foil 2, thereby realizing the oiling of the aluminum foil 2. Compared with the existing method of directly spraying lubricating oil on the aluminum foil 2 in front of the pressing roller 8, making the lubricating oil adhere to the aluminum foil 2, and then rolling the aluminum foil 2 after transmitting a certain distance, the present invention can make the lubricating oil directly contact the rolled position of the aluminum foil 2 after being sprayed, reducing the impact force required for the lubricating oil to be sprayed to the position between the aluminum foil 2 and the rolling plate 12, thereby reducing the amount of lubricating oil splashing outward. The lubricating effect of the lubricating oil on the position between the aluminum foil 2 and the rolling plate 12 is improved. Compared with the prior art that directly sprays the lubricating oil to the position between the aluminum foil 2 and the rolling plate 12, resulting in a larger impact force when the lubricating oil is sprayed to the position between the aluminum foil 2 and the rolling plate 12, causing the lubricating oil to splash everywhere, the present invention reduces the distance required for the lubricating oil to be sprayed to the position between the aluminum foil 2 and the rolling plate 12, so that the lubricating oil can be sprayed to the position between the aluminum foil 2 and the rolling plate 12 without a stronger impact force, thereby reducing the splashing of the lubricating oil and improving the lubricating effect of the lubricating oil on the position between the aluminum foil 2 and the rolling plate 12.

[0026] The following is an explanation using the driving member 4 located on the upper side. If the visual sensor on the connecting frame 5 observes that the aluminum foil 2 is broken during the rolling process of the rolling plate 12, the aluminum foil 2 loses the transmission traction to the right, and it is difficult to pass the broken end through between the upper and lower rolling plates 12 relying only on the conveyor belt 1 on the left, resulting in the aluminum foil 2 being stuck. The prior art is to stop the machine, manually disassemble the device, and then pull the broken part of the aluminum foil 2 through between the upper and lower rolling plates 12, so that the broken part of the aluminum foil 2 is disengaged from the position between the upper and lower rolling plates 12. The above method is complicated and takes too long, which affects the production efficiency of the aluminum foil 2. The present invention controls the driving member 4 located on the upper side to drive the connecting frame 5, the servo motor 6 and the rotating shaft 7 to move upward, thereby driving the pressure roller 8, the connecting pipe 9, the extrusion plate 10, the elastic member 11 and the rolling plate 12 to move upward. Similarly, by controlling the driving member 4 located on the lower side The driving member 4 drives the connecting frame 5, the servo motor 6 and the rotating shaft 7 located on the lower side to move downward, thereby driving the pressing roller 8, the connecting tube 9, the extrusion plate 10, the elastic member 11 and the rolling plate 12 located on the lower side to move downward, thereby increasing the distance between the upper and lower rolling plates 12 and the aluminum foil 2, so that after the rolling plate 12 contacts the aluminum foil 2, the elastic member 11 is compressed, and the rolling plate 12 moves toward the center of the pressing roller 8, but the rolling plate 12 does not directly contact the pressing roller 8, so that the rolling plate 12 does not roll the aluminum foil 2, but only squeezes the aluminum foil 2, and does not press the broken end of the aluminum foil 2, so that the broken end of the aluminum foil 2 is easier to pass between the upper and lower rolling plates 12, and at this time, the broken end of the aluminum foil 2 is moved to the right by the friction of the rotating rolling plate 12, so that the broken part of the aluminum foil 2 is detached from the position between the upper and lower rolling plates 12, thereby realizing the detachment processing of the broken aluminum foil 2 and improving production efficiency.

[0027] Each oil outlet groove 12002 is expanded on one side facing the cavity of the rolling plate 12, so as to increase the flow rate of the lubricating oil sprayed out of the oil outlet groove 12002, so that the lubricating oil contacts the aluminum foil 2 and the rolling plate 12 more quickly.

[0028] A drainage portion 10201 is provided inside the oil storage tank 102 , and the rear side of the drainage portion 10201 is tilted downward, so that the lubricating oil accumulates on the left side of the drainage portion 10201 , making it easier for the lubricating oil in the oil storage tank 102 to enter the oil delivery pipe 101 .

[0029] Example 2 On the basis of Example 1, Figure 2 and Figure 6-Figure 9As shown, an oil baffle plate 201 is also included; an oil baffle plate 201 is fixedly connected to the opposite sides of the two connecting frames 5; each oil baffle plate 201 is provided with an oil scraping surface 20101 on the side close to the aluminum foil 2, and each oil scraping surface 20101 is in contact with the surface of the aluminum foil 2; it is used to block the lubricating oil splashing to the right, so that the lubricating oil falls downward onto the aluminum foil 2, and then the lubricating oil on the aluminum foil 2 is scratched by the oil scraping surface 20101 on the oil baffle plate 201, so that the lubricating oil moves to the front and rear sides of the aluminum foil 2, and then falls downward into the oil storage bin 102, so as to collect the lubricating oil.

[0030] The oil baffle 201 is configured in a semicircular shape, so that the lubricating oil can fall downward onto the aluminum foil 2 in a more gentle manner, thereby facilitating the collection of the lubricating oil.

[0031] Each oil scraping surface 20101 is configured as an arc-shaped surface convex to the left in the middle, and is used to guide the lubricating oil scratched by the oil scraping surface 20101, so that the lubricating oil can more easily move to the front and rear sides of the aluminum foil 2, thereby facilitating the collection of the lubricating oil.

[0032] It also includes a guide plate 301; two front-to-back symmetrical guide plates 301 are fixedly connected to the upper side of each conveyor belt 1; they are used to limit and guide the aluminum foil 2 to prevent the aluminum foil 2 from separating from the conveyor belt 1 during the transmission process.

[0033] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
