Description

Technical Field

[0001] This invention relates to the field of aluminum alloy foil processing technology, and in particular to a high-performance aluminum alloy foil slitting device. Background Technology

[0002] Aluminum alloy foil is used in various fields. In recent years, from the point of view that it is thin and has conductivity, aluminum alloy foil has been used as a current collector for electrodes in energy storage devices such as lithium-ion batteries, double-layer capacitors, and lithium-ion capacitors.

[0003] In the production of aluminum alloy foil, it needs to be slit according to requirements to achieve a fixed length. However, existing slitting equipment lacks a protective structure for the slitting blades, making them prone to damage during slitting. Furthermore, existing slitting equipment often results in unstable stacked aluminum alloy foil structures, meaning that the alignment and tightness of the stacked aluminum alloy foils are poor when slitting, leading to inaccurate slitting results and affecting the quality of subsequent aluminum alloy foil production. Summary of the Invention

[0004] The purpose of this invention is to overcome the deficiencies in the prior art and provide a high-performance aluminum alloy foil slitting device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] This invention discloses a high-performance aluminum alloy foil slitting device, including a slitting table for slitting stacked aluminum alloy foil. Continuous aluminum alloy foil passes through the top of the slitting table. A slitting assembly is mounted above the slitting table. The slitting assembly includes a mounting frame, a hydraulic press unit, and a slitting blade. The mounting frame has a U-shaped structure and is mounted above the slitting table. The hydraulic press unit is mounted on top of the mounting frame. The slitting blade is located on the lower inner side of the mounting frame. The hydraulic rod on the hydraulic press unit for pushing the slitting blade is detachably connected to the slitting blade. A limiting frame is also installed between the two vertical ends of the mounting frame. The limiting frame has a strip-shaped opening in the middle, through which the slitting blade passes. In use, the continuous aluminum alloy foil to be slitted... The aluminum alloy foil is pushed by the conveying equipment over the slitting table. During the movement of the aluminum alloy foil, when the slitting position reaches the position of the slitting blade, the slitting blade moves downward under the action of the hydraulic unit, slitting the aluminum alloy foil at the slitting position. After slitting is completed, the slitting blade returns to its original position, and the slit aluminum alloy foil is pushed out of the slitting table and transported by the conveying equipment. In this device, the slitting blade and the hydraulic rod on the hydraulic unit are detachably connected. Therefore, if the slitting blade is damaged, it can be directly removed from the hydraulic rod for easy maintenance and replacement. In addition, a limit frame is installed between the two vertical ends of the mounting frame. The limit frame can limit the slitting blade and distribute the lateral stress of the slitting blade, reducing the occurrence of "blade breakage" and improving the service life of the device and the safety of the slitting process.

[0007] Preferably, a fastening plate is installed above the slitting blade body, and a connecting post is installed at the center of the top of the fastening plate. A connecting sleeve is movably fitted above the connecting post, and a plate structure is provided at the top of the connecting post to prevent the connecting sleeve from falling out. The hydraulic rod on the hydraulic unit used to push the slitting blade body has a threaded structure at its bottom and is connected to the connecting sleeve by threaded engagement. When it is necessary to disassemble the slitting blade body, it is only necessary to rotate the connecting sleeve. When the connecting sleeve is completely separated from the hydraulic rod, the slitting blade body can be removed from the device.

[0008] Preferably, the top of the slitting blade has a back plate along its length, and the back plate has a notch in the middle. The fastening plate can be fastened to the back plate by the notch and fixed by bolts. This structure allows the connecting column or connecting sleeve to be removed from the notch by sliding the fastening plate when it is damaged due to compression, making it easy to replace without replacing the entire slitting blade, thus reducing the maintenance cost of the device.

[0009] Preferably, at least two fastening plates are installed. When two fastening plates are installed, the two fastening plates are symmetrical about the vertical center line of the cutting blade. When multiple fastening plates are installed, the multiple fastening plates are distributed at equal intervals.

[0010] Preferably, a pressure plate for pressing the aluminum alloy foil is also provided on the lower inner side of the mounting frame. The top of the pressure plate is connected to one of the hydraulic rods of the hydraulic unit. The pressure plate can press the aluminum alloy foil before the slitting blade cuts it, ensuring the stability of the aluminum alloy foil during slitting and facilitating the slitting process.

[0011] Preferably, a clamping assembly for holding aluminum alloy foil is also installed above the slitting table. The clamping assembly includes a fixed clamping plate and a movable clamping plate. The fixed clamping plate and the movable clamping plate are parallel to each other and perpendicular to the slitting blade. The movable clamping plate can move in the horizontal direction to adjust the distance between the fixed clamping plate and the movable clamping plate. The fixed clamping plate and the movable clamping plate can clamp the aluminum alloy foil before slitting, which facilitates the subsequent slitting by the slitting blade.

[0012] Preferably, a groove is provided on the upper surface of the cutting table below the movable clamping plate. The groove is perpendicular to the movable clamping plate. A sliding member is installed at the bottom of the movable clamping plate and slides and engages in the groove. Therefore, the movable clamping plate is more stable during horizontal movement due to the limiting effect of the sliding member and the groove.

[0013] Preferably, the cross-section of the slider is T-shaped.

[0014] Preferably, the upper surface of the slitting table is provided with a through groove in a direction perpendicular to the fixed clamping plate between the fixed clamping plate and the movable clamping plate. A front baffle is movably installed in the through groove. A control component for driving the front baffle to rise and fall is provided below the slitting table. The front baffle can be used to position the aluminum alloy foil to be slitted, ensuring that it can be aligned and that the subsequent slitting position is accurate.

[0015] Preferably, the control component includes an assembly plate frame, a rack, and a motor. The assembly plate frame is fixedly installed below the cutting table at a position in the through slot. A mounting slot is formed on the inner side of the assembly plate frame along the vertical direction. The rack is fixedly installed below the front baffle and is vertically arranged. The motor is fixedly installed on one side of the assembly plate frame. A gear is meshed below the rack. A rotating shaft is installed on the output shaft of the motor and is connected to the gear. When the motor is running, it drives the gear to rotate through the rotating shaft. Since the gear meshes with the rack, the rotation of the gear drives the rack to move up and down in the vertical direction, thereby realizing the raising and lowering of the front baffle.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The slitting blade body in this device is detachably connected to the hydraulic rod on the hydraulic unit. Therefore, when the slitting blade body is damaged, it can be directly removed from the hydraulic rod for easy repair and replacement. In addition, a limit frame is installed between the two vertical ends of the mounting frame. The limit frame can limit the slitting blade body and distribute the lateral stress of the slitting blade body, reducing the occurrence of "blade breakage", improving the service life of the device and the safety of the slitting process.

[0018] The device has a pressure plate and a clamping assembly installed on the lower inner side of the mounting frame. The pressure plate can press the aluminum alloy foil before the slitting blade cuts it, while the fixed clamping plate and movable clamping plate in the clamping assembly can clamp the aluminum alloy foil before it is cut. This can fully ensure the stability of the aluminum alloy foil during cutting and facilitate the subsequent cutting by the slitting blade. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 The following describes a specific embodiment of the high-performance aluminum alloy foil slitting device of the present invention. The high-performance aluminum alloy foil slitting device of the present invention is not limited to the description in the following embodiments.

[0028] Example 1:

[0029] This embodiment provides a high-performance aluminum alloy foil slitting device, such as... Figure 1-7 As shown, the assembly includes a slitting table 1 for slitting stacked aluminum alloy foil. Continuous aluminum alloy foil passes through the top of the slitting table 1. A slitting assembly is installed above the slitting table 1. The slitting assembly includes a mounting frame 5, a hydraulic press 4, and a slitting blade 17. The mounting frame 5 adopts a U-shaped structure and is mounted above the slitting table 1. The hydraulic press 4 is mounted on the top of the mounting frame 5. The slitting blade 17 is located on the lower inner side of the mounting frame 5. The hydraulic rod 22 on the hydraulic press 4 for pushing the slitting blade 17 is detachably connected to the slitting blade 17. A limit frame 18 is also installed between the two vertical ends of the mounting frame 5. The limit frame 18 has a strip-shaped opening in the middle, through which the slitting blade 17 passes.

[0030] By adopting the above technical solution:

[0031] When the device is in use, firstly, the continuous aluminum alloy foil to be cut passes above the cutting table 1 under the push of the conveying equipment. During the movement of the aluminum alloy foil, when the cutting position reaches the position of the cutting blade 17, the cutting blade 17 moves down under the action of the hydraulic unit 4 and cuts the aluminum alloy foil at the cutting position. After the cutting is completed, the cutting blade 17 is reset, and the cut aluminum alloy foil is pushed out of the cutting table 1 and then transported by the conveying equipment.

[0032] In this device, the slitting blade 17 is detachably connected to the hydraulic rod 22 on the hydraulic unit 4. Therefore, when the slitting blade 17 is damaged, it can be directly removed from the hydraulic rod 22 for easy repair and replacement. In addition, a limit frame 18 is installed between the two vertical ends of the mounting frame 5. The limit frame 18 can limit the slitting blade 17 and distribute the lateral stress of the slitting blade 17, reducing the occurrence of "blade breakage" and improving the service life of the device and the safety of the slitting process.

[0033] Example 2

[0034] Based on Embodiment 1, in this embodiment, a fastening plate 19 is installed above the slitting blade body 17, a connecting post 24 is installed at the center of the top of the fastening plate 19, a connecting sleeve 20 is movably sleeved above the connecting post 24, and a plate structure is provided on the top of the connecting post 24 to prevent the connecting sleeve 20 from coming off. The hydraulic rod 22 on the hydraulic unit 4 used to push the slitting blade body 17 has a threaded structure at the bottom and is connected to the connecting sleeve 20 by threaded engagement. When it is necessary to disassemble the slitting blade body 17, it is only necessary to rotate the connecting sleeve 20. When the connecting sleeve 20 is completely separated from the hydraulic rod 22, the slitting blade body 17 can be disassembled from the device.

[0035] The top of the slitting blade 17 has a back plate 23 along its length. The back plate 23 has a notch 21 in the middle. The fastening plate 19 can be fastened to the back plate 23 by the notch 21 and fixed by bolts.

[0036] At least two snap-fit ​​plates 19 are installed. When two snap-fit ​​plates 19 are installed, the two snap-fit ​​plates 19 are symmetrical about the vertical center line of the cutting blade body 17. When multiple snap-fit ​​plates 19 are installed, the multiple snap-fit ​​plates 19 are distributed at equal intervals.

[0037] By adopting the above technical solution:

[0038] When the connecting column 24 or the connecting sleeve 20 is damaged due to compression, it can be removed from the notch 21 by sliding the fastening plate 19, making it easy to replace without replacing the entire slitting blade body 17, thus reducing the maintenance cost of the device.

[0039] Example 3

[0040] Based on Embodiment 1, in this embodiment, a pressure plate 25 for pressing aluminum alloy foil is also provided on the lower inner side of the mounting frame 5. The top of the pressure plate 25 is connected to one of the hydraulic rods 22 of the hydraulic unit 4. The pressure plate 25 can press the aluminum alloy foil before the slitting blade 17 cuts it, ensuring the stability of the aluminum alloy foil during slitting and facilitating slitting.

[0041] Above the slitting table 1, a clamping assembly for holding aluminum alloy foil is also installed. The clamping assembly includes a fixed clamping plate 7 and a movable clamping plate 3. The fixed clamping plate 7 and the movable clamping plate 3 are parallel to each other and perpendicular to the slitting blade body 17. The movable clamping plate 3 can move in the horizontal direction. Preferably, a fixed plate 2 is installed above the slitting table 1. A cylinder 10 is installed on one side of the fixed plate 2. The piston rod of the cylinder 10 is fixedly connected to one side of the movable clamping plate 3.

[0042] A groove 9 is provided on the upper surface of the slitting table 1 below the movable clamping plate 3. The groove 9 is perpendicular to the movable clamping plate 3. A sliding member 8 is installed at the bottom of the movable clamping plate 3. The sliding member 8 is slidably engaged in the groove 9. Therefore, the movable clamping plate 3 has higher stability during horizontal movement due to the limiting effect of the sliding member 8 and the groove 9.

[0043] The cross-section of slider 8 is T-shaped.

[0044] The upper surface of the slitting table 1 is provided with a through groove 16 between the fixed clamping plate 7 and the movable clamping plate 3 in a direction perpendicular to the fixed clamping plate 7. A front baffle 6 is movably installed in the through groove 16. A control component for driving the front baffle 6 to rise and fall is provided below the slitting table 1. The front baffle 6 can be used to position the aluminum alloy foil to be slitted, ensuring that it can be aligned and that the subsequent slitting position is accurate.

[0045] By adopting the above technical solution:

[0046] The aluminum alloy foil can be clamped before slitting by the fixed clamping plate 7 and the movable clamping plate 3, which facilitates the subsequent slitting by the slitting blade 17.

[0047] Example 4

[0048] Based on Embodiment 1, in this embodiment, the control component includes an assembly plate frame 15, a rack 11, and a motor 12. The assembly plate frame 15 is fixedly installed below the cutting table 1 at the position of the through slot 16. A mounting slot 14 is opened on the inner side of the assembly plate frame 15 in the vertical direction. The rack 11 is fixedly installed below the front baffle 6 and is vertically arranged. The motor 12 is fixedly installed on one side of the assembly plate frame 15. A gear 13 is meshed and installed below the rack 11. A rotating shaft is installed on the output shaft of the motor 12 and is connected to the gear 13.

[0049] By adopting the above technical solution:

[0050] When the motor 12 is running, it drives the gear 13 to rotate through the rotating shaft. Since the gear 13 meshes with the rack 11, the rotation of the gear 13 drives the rack 11 to rise and fall in the vertical direction, thereby realizing the raising and lowering of the front baffle 6.
