Description

Technical Field

[0001] The invention belongs to the technical field of aluminum foil processing, and particularly relates to an aluminum foil coil calendering forming device and a forming method. Background Art

[0002] Aluminum foil coil is a product made by rolling aluminum ingots into extremely thin foil materials and then rolling them into a tube. It has the characteristics of light texture, corrosion resistance, excellent thermal and electrical conductivity, and strong barrier properties. It is widely used in food and drug packaging, building insulation, electronics industry, aerospace and other fields.

[0003] The aluminum foil coil calendering device is a key equipment used for aluminum foil coil calendering. It stretches and deforms the material under pressure through the extrusion of upper and lower rollers. At the same time, with the help of high-precision roll gap adjustment, tension control and temperature management, it can achieve precise control of the thickness, flatness and surface quality of the aluminum foil. It is the core forming equipment to ensure that the aluminum foil coil meets the application needs of different industries.

[0004] The patent application with patent publication number CN220611727U discloses a metal aluminum foil calendering machine. When the dual-axis motor is working, the dust removal brush connected to the bottom of the dual-axis motor will rotate. Since the dust removal brush is in contact with the upper surface of the metal aluminum foil, the surface of the metal aluminum foil can be dusted when the dust removal brush rotates. Although the device can remove dust from the surface of the metal aluminum foil and can calender the metal aluminum foil, in actual use, the metal aluminum foil needs to be stretched by an auxiliary roller. However, there is a height difference between the auxiliary roller and the feed roller and the winding roller. To stretch the metal aluminum foil, the metal aluminum foil needs to pass through the bottom of the feed roller first, then pass through the top of the two auxiliary rollers, and finally connect with the winding roller. The operation is relatively inconvenient in the process of conveying the metal aluminum foil and connecting the end of the metal aluminum foil with the winding roller, which consumes a lot of time and reduces work efficiency.

[0016] S2: Place the first winding reel with the aluminum foil wound on it on the outside of the unwinding roller, and place the empty second winding reel on the outside of the winding roller.

[0017] S3: The unwinding roller is rotated, and the metal aluminum foil is guided between one set of upper clamping plates and lower clamping plates under the action of the guide support plate. With the cooperation of one set of upper clamping plates and lower clamping plates, the end of the metal aluminum foil is clamped, and the metal aluminum foil is driven to move horizontally through the cooperation of the third motor and the lead screw to clean the surface of the metal aluminum foil, and the end of the metal aluminum foil is made to enter between the pressing rollers to be rolled.

During the movement, the U-shaped frame cooperates with the slide, the first guide groove and the second guide groove to move the upper tensioning roller to the bottom of the slide, and move the lower tensioning roller to the top of the slide, so that the upper tensioning roller contacts the upper surface of the metal aluminum foil, and the lower tensioning roller contacts the lower surface of the metal aluminum foil, thereby tensioning the metal aluminum foil.

[0020] Beneficial effects of the present invention: 1) The unwinding roller rotates, and under the action of the guide support plate, the metal aluminum foil is guided between one group of upper clamping plates and the lower clamping plates. Under the cooperation of one group of upper clamping plates and the lower clamping plates, the end of the metal aluminum foil is clamped. Under the cooperation of the third motor and the screw rod, the metal aluminum foil is driven to move horizontally, and the metal aluminum foil is driven to pass through the brush roller to clean the surface of the metal aluminum foil. When one group of upper clamping plates and the lower clamping plates move to a position close to the pressing roller, the end of the metal aluminum foil enters between the pressing rollers, so that the metal aluminum foil is rolled; the rolled metal aluminum foil passes through the pressing roller and corresponds to another group of upper clamping plates and the lower clamping plates. Under the cooperation of the other group of upper clamping plates and the lower clamping plates, the end of the metal aluminum foil is clamped. Under the cooperation of the third motor and the screw rod, the other group of upper clamping plates and the lower clamping plates are driven to move to a position close to the winding roller, so that the metal aluminum foil can be fixed on the second winding disk, and the metal aluminum foil can be transported horizontally. It is more convenient to transport the metal aluminum foil and can improve work efficiency.

[0021] 2) After the metal aluminum foil is fixed, start the unwinding roller, the first motor and the second motor. The second motor drives one of the gears to rotate, and one of the gears, in cooperation with the third sprocket and the second chain, causes the other gear to rotate synchronously. The two gears drive the rack to move during the rotation, and the rack movement drives the U-shaped frame to move. During the movement, the U-shaped frame cooperates with the chute, the first guide groove and the second guide groove to move the upper tensioning roller to the bottom of the chute and the lower tensioning roller to the top of the chute, so that the upper tensioning roller contacts the upper surface of the metal aluminum foil and the lower tensioning roller contacts the lower surface of the metal aluminum foil, thereby tensioning the metal aluminum foil. After the metal aluminum foil is tensioned, the winding roller is rotated to realize the calendering and winding of the metal aluminum foil. By adjusting the positions of the upper tensioning roller and the lower tensioning roller, the metal aluminum foil can be tensioned after it is conveyed, which can ensure the calendering quality of the metal aluminum foil.

[0063] Working principle: In the initial state, one set of the upper clamping plates 51 and the lower clamping plates 5 are located near the guide support plate 16, and the other set of the upper clamping plates 51 and the lower clamping plates 5 are located near the pressure roller 2. The upper tensioning roller 3 is located above the chute 32, and the lower tensioning roller 31 is located below the chute 32. Start the first motor 22, the first motor 22 drives the pressure roller 2 to rotate, and with the cooperation of the first sprocket 23, the second sprocket 24 and the first chain 25, the pressure roller 2 and the brush roller 21 rotate synchronously; The first winding reel 12 with the metal aluminum foil 13 wound on it is placed on the outside of the unwinding roller 11, and the empty second winding reel 15 is placed on the outside of the winding roller 14. After the first winding reel 12 and the second winding reel 15 are placed, the unwinding roller 11 is rotated, and the metal aluminum foil 13 is guided between one group of upper clamping plates 51 and the lower clamping plates 5 under the action of the guide support plate 16. At this time, under the action of the control system and the detector, the unwinding roller 11 stops running and the electric cylinder 61 is started. The electric cylinder 61 drives the upper clamping plates 51 to descend, and with the cooperation of one group of upper clamping plates 51 and the lower clamping plates 5, the end of the metal aluminum foil 13 is clamped, and then placed. The winding roller 11 continues to rotate, and at the same time, the third motor 55 drives the screw rod 54 to rotate. The rotation of the screw rod 54 drives one set of the upper clamping plates 51 and the lower clamping plates 5 to move. During the movement, one set of the upper clamping plates 51 and the lower clamping plates 5 drives the metal aluminum foil 13 to move horizontally, and drives the metal aluminum foil 13 to pass through the brush roller 21 to clean the surface of the metal aluminum foil 13. When one set of the upper clamping plates 51 and the lower clamping plates 5 moves to a position close to the pressing roller 2, the electric cylinder 61 starts to drive the upper clamping plate 51 to rise, so that the end of the metal aluminum foil 13 loses the clamping and enters between the pressing rollers 2, so that the metal aluminum foil 13 is rolled; The rolled aluminum foil 13 passes through the pressure roller 2 and corresponds to another set of upper clamping plates 51 and lower clamping plates 5. At this time, under the action of the control system and the detector, the unwinding roller 11 and the third motor 55 will stop running and the electric cylinder 61 will be started. The electric cylinder 61 drives the upper clamping plate 51 to descend. With the cooperation of another set of upper clamping plates 51 and lower clamping plates 5, the end of the aluminum foil 13 is clamped. After clamping, the unwinding roller 11 continues to rotate, the first motor 22 is started to rotate the pressure roller 2 and the brush roller 21, and the third motor 55 is started to drive the wire The rod 54 rotates to move the other set of upper clamping plates 51 and the descending plate. When the other set of upper clamping plates 51 and the lower clamping plates 5 move to a position close to the winding roller 14, the unwinding roller 11, the first motor 22 and the third motor 55 stop running, and the electric cylinder 61 starts to drive the upper clamping plates 51 to rise, so that the end of the metal aluminum foil 13 loses its grip. At this time, the metal aluminum foil 13 can be fixed on the second winding drum 15, and the metal aluminum foil 13 can be transported horizontally, which is more convenient when transporting the metal aluminum foil 13 and can improve work efficiency. After the metal aluminum foil 13 is fixed, the unwinding roller 11, the first motor 22 and the second motor 45 are started. The second motor 45 drives one of the gears 42 to rotate. One of the gears 42 rotates synchronously with the cooperation of the third sprocket 43 and the second chain 44. The two gears 42 drive the rack 4 to move during the rotation, and the movement of the rack 4 drives the U-shaped frame 34 to move. During the movement, the U-shaped frame 34 cooperates with the slide groove 32, the first guide groove 35 and the second guide groove 36 to move the upper tensioning roller 3 to The upper tensioning roller 3 is moved to the bottom of the chute 32, and the lower tensioning roller 31 is moved to the top of the chute 32, so that the upper tensioning roller 3 contacts the upper surface of the metal aluminum foil 13, and the lower tensioning roller 31 contacts the lower surface of the metal aluminum foil 13, thereby tensioning the metal aluminum foil 13. After the metal aluminum foil 13 is tensioned, the winding roller 14 is rotated to realize the calendering and winding of the metal aluminum foil 13. By adjusting the positions of the upper tensioning roller 3 and the lower tensioning roller 31, the metal aluminum foil 13 can be tensioned after being conveyed, which can ensure the calendering quality of the metal aluminum foil 13.

[0064] A method for calendering an aluminum foil coil comprises the following steps: S1: Start the first motor 22 , the first motor 22 drives the pressure roller 2 to rotate, and with the cooperation of the first sprocket 23 , the second sprocket 24 and the first chain 25 , the pressure roller 2 and the brush roller 21 rotate synchronously.

[0065] S2: Place the first winding reel 12 with the aluminum foil 13 wound on it outside the unwinding roller 11 , and place the empty second winding reel 15 on the outside of the winding roller 14 .

[0066] S3: The unwinding roller 11 is rotated, and under the action of the guide support plate 16, the metal aluminum foil 13 is guided between one set of upper clamping plates 51 and the lower clamping plates 5.
