Description

Technical Field

[0001] This utility model relates to the technical field of metal foil cleaning line equipment, specifically to a degreasing section structure of an aluminum alloy foil cleaning line. Background Technology

[0002] During the rolling process, aluminum alloy foil will have detached metal shavings, foreign matter, or rolling oil adhering to its surface. Therefore, after the aluminum alloy foil is rolled, it must be cleaned by an aluminum alloy foil cleaning machine before proceeding with other processes to improve the surface cleanliness of the aluminum alloy foil.

[0003] Currently, there are two types of aluminum alloy foil cleaning machines: spray type and immersion type. Spray cleaning involves spraying high-pressure liquid onto the surface of the aluminum alloy foil, which has high cleaning efficiency but poor cleaning effect and cannot completely remove residual metal shavings from the surface of the aluminum alloy foil. Immersion cleaning involves immersing the aluminum alloy foil in the cleaning solution and applying ultrasonic waves to the cleaning solution to improve the cleaning effect, but its cleaning efficiency is lower. Therefore, how to simultaneously ensure the cleaning effect and high cleaning efficiency of aluminum alloy foil is a contradiction that the aluminum alloy foil cleaning industry urgently needs to solve. Utility Model Content

[0004] To overcome the shortcomings in the prior art, this utility model discloses a degreasing section structure for an aluminum alloy foil cleaning line. Based on the existing spray cleaning structure, several cleaning roller assemblies are added. While the aluminum alloy foil is being cleaned by high-pressure spray, the cleaning roller assemblies also provide mechanical assistance in cleaning the aluminum alloy foil, thereby resolving the contradiction between the cleaning effect and cleaning efficiency of the aluminum alloy foil.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution: a degreasing section structure for an aluminum alloy foil cleaning line, comprising a cleaning chamber, a base, a cleaning roller assembly, and a squeezing roller. The cleaning roller assembly includes a pair of cleaning rollers, a cleaning roller bracket, and a cleaning roller drive device. The cleaning roller bracket has two support frames. The cleaning chamber and support frames are fixedly mounted on the upper part of the base, with the support frames located outside the opposite side walls of the cleaning chamber. The cleaning roller pair is rotatably mounted inside the cleaning chamber. Both ends of the cleaning roller pair are slidably connected to the support frames via cleaning roller bearing seats. The cleaning roller drive device is connected to one end of the cleaning roller pair via a universal joint shaft, driving the cleaning roller pair to rotate. The squeezing roller is rotatably mounted at the inlet and outlet ports at both ends of the cleaning chamber.

[0006] Furthermore, the cleaning roller pair includes a cleaning brush roller and a cleaning support roller, which are arranged in an up-and-down contact configuration. An upper cleaning roller adjustment device is provided at the upper end of the support frame, and a lower cleaning roller adjustment device is provided at the lower end. The upper or lower cleaning roller adjustment device is connected to the cleaning roller bearing seat through a connecting device to drive the cleaning brush roller or the cleaning support roller to move up and down.

[0007] Furthermore, there are several cleaning roller assemblies; the cleaning brush rollers and cleaning support rollers of adjacent cleaning roller assemblies are arranged alternately, and the cleaning brush rollers and cleaning support rollers are arranged alternately at the contact points.

[0008] Furthermore, the lower cleaning roller adjustment device includes a drive motor, a reduction gearbox, and a lifting adjustment box. There are two lifting adjustment boxes, which are fixedly installed at the bottom of the two support frames respectively. The two lifting adjustment boxes are connected by a synchronous shaft of the lifting adjustment box.

[0009] Furthermore, a synchronous shaft isolation tube is installed between the two opposite side walls of the cleaning chamber, and the synchronous shaft of the lifting adjustment box is installed in the synchronous shaft isolation tube, which is isolated from the internal space of the cleaning chamber.

[0010] Furthermore, there are two upper cleaning roller adjustment devices, which are fixedly installed on the upper part of the support frame.

[0011] Furthermore, the connecting device is a connecting bolt, with threads of opposite directions at both ends. The connecting bolt connects the upper or lower cleaning roller adjusting device to the cleaning roller bearing seat through the threads of opposite directions at both ends.

[0012] Preferably, the connecting device includes a connector, a connecting seat, a connecting block, and a connecting pin. The connector is connected to the connecting seat, the connecting block is fixedly connected to the washing roller bearing seat, and the connecting seat and the connecting block are connected by the connecting pin.

[0013] Furthermore, a bearing seat slider is provided between the adjacent surfaces of the cleaning roller bearing seat and the support frame, which restricts the radial movement of the cleaning brush roller or cleaning support roller when it moves up and down.

[0014] Furthermore, a guide rail is fixedly installed on the outer end face of the support frame, and a guide rail pressure block is fixedly installed on the outer end face of the cleaning roller bearing seat. The guide rail and the guide rail pressure block cooperate to restrict the axial movement of the cleaning brush roller or cleaning support roller when it moves up and down.

[0015] Furthermore, the cleaning roller support is equipped with a cleaning roller disassembly guide rail, and the lower part of the cleaning roller bearing seat on the lower side is equipped with a cleaning roller disassembly guide wheel; when the cleaning roller is installed or disassembled, the cleaning roller disassembly guide wheel falls on the cleaning roller disassembly guide rail and moves horizontally along the cleaning roller disassembly guide rail.

[0016] By adopting the technical solution described above, this utility model has the following beneficial effects: The degreasing section structure of the aluminum alloy foil cleaning line disclosed in this utility model adds several cleaning roller assemblies to the existing spray cleaning structure. While the aluminum alloy foil is being cleaned by high-pressure spray, the cleaning roller assemblies also provide mechanical assistance in cleaning the aluminum alloy foil, thereby resolving the contradiction between the cleaning effect and cleaning efficiency of the aluminum alloy foil.

Detailed Implementation

[0030] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0031] See the instruction manual appendix Figure 1 , 2 A degreasing section structure for an aluminum alloy foil cleaning line includes a cleaning box 1, a base 2, a cleaning roller assembly 3, and a squeezing roller 5 (the squeezing roller 5 is attached to the base). Figure 1 , 2 (not shown in the image)

[0032] See the instruction manual appendix Figure 3 The cleaning chamber 1 is a thin-walled steel plate welded structure, in which a through synchronous shaft isolation pipe 1.1 and a high-pressure spray pipe 1.2 are welded between the front and rear side walls;

[0033] See the instruction manual appendix Figure 4 Base 2 is a rectangular frame structure welded from steel profiles;

[0034] See the instruction manual appendix Figure 5 The cleaning roller assembly 3 includes a cleaning roller pair 3.1, a cleaning roller bracket 3.2, and a cleaning roller drive device 3.3. The cleaning roller drive device 3.3 can be a combination of a motor and a gearbox, or a hydraulic motor.

[0035] See the instruction manual appendix Figure 7The cleaning roller pair 3.1 includes a cleaning brush roller 3.1.1 and a cleaning support roller 3.1.2. The cleaning brush roller 3.1.1 has a nylon cleaning brush on its outer circumference, and the cleaning support roller 3.1.2 has an elastic rubber layer on its outer circumference. The cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are arranged vertically, with the ends of the cleaning brushes abutting against the elastic rubber layer. Both ends of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are provided with cleaning roller bearing seats 3.1.3, and both ends of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are rotatably connected to the cleaning roller bearing seats 3.1.3 through bearings. Bearing seat sliders A3.1.5 are fixedly provided on both the left and right sides of the cleaning roller bearing seat 3.1.3, and the lower part of the cleaning roller bearing seat 3.1.3 is provided with a cleaning roller disassembly guide wheel 3.1.4.

[0036] See the instruction manual appendix Figure 8 The cleaning roller bracket 3.2 includes a support frame 3.2.1, a cleaning roller assembly / disassembly guide rail 3.2.2, a support beam 3.2.3, an upper cleaning roller adjustment device 3.2.4, and a lower cleaning roller adjustment device 3.2.5. The support frame 3.2.1 consists of two rectangular frames welded from steel plates, including left and right vertical plates and upper and lower end plates. Bearing seat sliders B 3.2.7 are fixedly mounted on the opposite surfaces of the left and right vertical plates. The upper cleaning roller adjustment device 3.2.4 is fixedly mounted on the upper part of the upper end plate, and a lifting adjustment box 3.2.5.1 is fixedly mounted on the upper part of the lower end plate. The upper cleaning roller adjustment device 3.2.4 is a bidirectional drive hydraulic cylinder controlled by a hydraulic servo system. A connector 3.2.6 is fixedly mounted at the lower end of the drive shaft of the upper cleaning roller adjustment device 3.2.4. The lower end of the connector 3.2.6 has a T-shaped connector. The outer end face of the connector is a ball head; the lifting adjustment box 3.2.5.1 is a mechanical telescopic drive device, which is equipped with a rotary input shaft, a rotary output shaft, and a telescopic output shaft. The lower cleaning roller adjustment device 3.2.5 converts the rotational motion input by the rotary input shaft into the up-and-down motion of the telescopic output shaft. The upper end of the telescopic output shaft is also fixedly equipped with a connector 3.2.6; of the two lifting adjustment boxes 3.2.5.1, one of them is connected to a drive motor and a reduction gearbox through a coupling. The two lifting adjustment boxes 3.2.5.1 are synchronously connected through the rotary input shaft and the rotary output shaft using the lifting adjustment box synchronous shaft 3.2.5.2 to ensure that the telescopic output shafts of the two lifting adjustment boxes 3.2.5.1 move up and down synchronously; the two support frames 3.2.1 are fixedly connected through the cleaning roller disassembly guide rail 3.2.2 and the support beam 3.2.3.

[0037] See the instruction manual appendix Figure 1 , 211: The cleaning chamber 1 and the support frame 3.2.1 are fixedly installed on the upper part of the base 2. The support frame 3.2.1 is located on the outside of the opposite side walls of the cleaning chamber 1. The lifting adjustment box synchronous shaft 3.2.5.2 is installed in the synchronous shaft isolation tube 1.1, which is isolated from the internal space of the cleaning chamber 1. After the lifting adjustment box synchronous shaft 3.2.5.2 is isolated from the internal space of the cleaning chamber 1, the sealing leakage problem that exists when the lifting adjustment box synchronous shaft 3.2.5.2 directly penetrates the internal space of the cleaning chamber 1 is completely solved. The opposite side walls of the cleaning chamber 1 are provided with cleaning roller mounting grooves corresponding to the support frame 3.2.1.

[0038] For the installation of the cleaning roller pair 3.1, please refer to the instruction manual appendix. Figure 9 A cleaning roller disassembly support 4 is installed between the two end cleaning roller bearing seats 3.1.3. The cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are temporarily connected through the cleaning roller disassembly support 4. Then, the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are connected to the cleaning roller drive device 3.3 at one end, passing through the cleaning roller mounting groove on the side wall of the cleaning box 1 away from the cleaning roller drive device 3.3. The cleaning roller disassembly guide wheel 3.1.4 is set on the cleaning roller disassembly guide rail 3.2.2, pushing the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 to move horizontally along the cleaning roller disassembly guide rail 3.2.2 towards the side of the cleaning roller drive device 3.3 until the cleaning roller shaft... The outer side of the bearing seat 3.1.3 is roughly aligned with the outer side of the left and right vertical plates of the support frame 3.2.1. After the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are roughly installed in place, the bearing seat sliders A3.1.5 on the left and right sides of the cleaning roller bearing seat 3.1.3 cooperate with the bearing seat sliders B3.2.7 fixed on the opposite surfaces of the left and right vertical plates of the support frame 3.2.1 to achieve radial limitation when the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 move up and down. The fit clearance between the bearing seat sliders A3.1.5 and B3.2.7 is obtained through actual fitting during the assembly process to solve the problem of large welding structure error of the support frame 3.2.1.

[0039] The above-described installation method of the cleaning roller pair 3.1 has the following advantages: 1. Since the cleaning roller pair 3.1 is installed horizontally from the side of the cleaning chamber 1, it is not necessary to remove the top cover plate of the cleaning chamber 1, nor is it necessary to remove the upper end plate of the support frame 3.2.1 and the upper cleaning roller adjustment device 3.2.4 during installation and disassembly. This has the advantages of low workload and high efficiency in installation and disassembly; 2. Since it is not necessary to remove the upper end plate of the support frame 3.2.1 during installation and disassembly, the fit clearance between the bearing seat slider A3.1.5 and the bearing seat slider B3.2.7 will not be damaged. This eliminates the need to re-fit the fit clearance between the bearing seat slider A3.1.5 and the bearing seat slider B3.2.7 every time the cleaning roller pair 3.1 is installed and disassembled; 3. Cleaning wool When the cleaning roller bearing seats 3.1.3 at both ends of the brush roller 3.1.1 and the cleaning support roller 3.1.2 are connected to the upper cleaning roller adjustment device (3.2.4) or the lower cleaning roller adjustment device (3.2.5), it can be achieved by supporting the cleaning roller disassembly guide rail 3.2.2 without the need for additional auxiliary assembly support. This has the advantages of stable support and low auxiliary workload during assembly. Due to the advantages of the cleaning roller installation method described above in 3.1, the efficiency of installation and disassembly of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 is greatly improved (during the operation of the degreasing section of the aluminum alloy foil cleaning line, the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are worn and need to be disassembled and replaced regularly), thereby improving the equipment utilization rate.

[0040] After the cleaning roller assembly 3.1 is installed in place, the cleaning roller bearing housing 3.1.3 and the connector 3.2.6 are connected via the connector 3.4, the connector 3.5, and the connector pin 3.6. The specific connection between the cleaning roller bearing housing 3.1.3 and the connector 3.2.6 of the upper cleaning roller adjusting device 3.2.4 is described below: (See attached instruction manual) Figure 7 The upper (or lower) part of the cleaning roller bearing housing 3.1.3 is provided with a bearing housing mounting groove 3.1.3.1; see the appendix of the instruction manual. Figure 10 The connecting seat 3.4 is a rectangular block with a T-slot at the top and a through hole at the bottom; the connecting block 3.5 is a rectangular plate with a through hole on its surface; when connecting the cleaning roller bearing seat 3.1.3 and the connecting head 3.2.6, first, the lower part of the connecting seat 3.4 is placed in the bearing seat mounting groove 3.1.3.1 of the cleaning roller bearing seat 3.1.3, and the T-shaped connector of the connecting head 3.2.6 is inserted into the bearing seat mounting groove 3.1.3.1 at the top of the connecting seat 3.4. The connecting block 3.5 is fixed to the left and right end faces of the cleaning roller bearing seat 3.1.3 by bolts. Finally, the connecting pin 3.6 is inserted into the through holes of the connecting seat 3.4 and the connecting block 3.5, thus achieving the connection between the cleaning roller bearing seat 3.1.3 and the connecting head 3.2.6.

[0041] The axial limiting of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 during their up-and-down movement is achieved through the cooperation of the guide rail 3.7 and the guide rail pressure block 3.8; see the appendix of the instruction manual. Figure 6 The guide rail 3.7 is plate-shaped and is fixed to the outer side of the left and right upright plates of the support frame 3.2.1 by bolts. The guide rail pressure block 3.8 is a rectangular block with a pressure groove on one side and is fixed to the left and right sides of the outer end face of the cleaning roller bearing seat 3.1.3 by bolts. The bottom surface of the pressure groove of the guide rail pressure block 3.8 abuts against the outer side of the guide rail 3.7. When the guide rails 3.7 and guide rail pressure blocks 3.8 at both ends of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 are all assembled, the axial direction of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 is limited, thereby realizing the axial movement limit when the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 move up and down; guide rail pressure block 3.8 The clearance between the contact surface of the guide rail 3.7 and the cleaning roller pair 3.1 needs to be precisely determined during the assembly process. After the cleaning roller pair 3.1 is installed, the clearance between the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 is increased by adjustment. The cleaning roller disassembly support 4 is then removed, and the cleaning roller drive device 3.3 is connected to the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 via a universal joint shaft. It should be noted that the universal joint shaft is equipped with axial sliding sleeves at both ends to adapt to the change in distance between the shaft ends of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 and the cleaning roller drive device 3.3 when the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 move up and down.

[0042] In the degreasing section of the aluminum alloy foil cleaning line, the cleaning roller assembly 3 can be configured with two, three, or four rollers as needed; see the attached instruction manual. Figure 12 The attached figure shows a case where four cleaning roller assemblies 3 are set in the degreasing section of the aluminum alloy foil cleaning line. In the four cleaning roller assemblies 3, the cleaning brush rollers 3.1.1 and cleaning support rollers 3.1.2 of adjacent cleaning roller assemblies 3 are arranged alternately to ensure the cleaning effect on the upper and lower surfaces of the aluminum alloy foil 6.

[0043] Before the degreasing section of the aluminum alloy foil cleaning line begins operation, the height of each cleaning roller pair 3.1 is adjusted using the upper cleaning roller adjustment device 3.2.4 and the lifting adjustment box 3.2.5.1 in the cleaning roller assembly 3. This ensures that the contact points between the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 in adjacent cleaning roller assemblies 3 are staggered vertically. This arrangement guarantees that at each cleaning roller pair 3.1, the aluminum alloy foil 6 can be wrapped around the outer circumference of the cleaning support roller 3.1.2 at a certain angle. The reason for this arrangement is that during operation, the cleaning roller pair 3.1 cleans... There will be a certain "pre-pressure" at the contact point between the cleaning brush on brush roller 3.1.1 and the cleaning support roller 3.1.2, causing the cleaning brush to bend and apply cleaning pressure to the aluminum alloy foil 6. Therefore, there is a surface contact between the cleaning brush and the aluminum alloy foil 6. If the aluminum alloy foil 6 is in point contact with the outer circumference of the cleaning support roller 3.1.2 (the aluminum alloy foil 6 does not have a wrapping angle on the outer circumference of the cleaning support roller 3.1.2), a gap will appear on the back of the contact surface between the aluminum alloy foil 6 and the cleaning brush (this part is unsupported). Due to the thickness of the aluminum alloy foil 6... The aluminum alloy foil 6 used in lithium batteries is extremely thin (its thickness is between 0.08-0.016 mm). When the aluminum alloy foil 6 is exposed, the gaps can cause localized cracking or breakage under the deformation pressure of the cleaning brush and the force of high-speed rotation, leading to production accidents during the cleaning process. This is why mechanical cleaning is not used for the existing aluminum alloy foil 6. Furthermore, when the contact points of the cleaning brush roller 3.1.1 and the cleaning support roller 3.1.2 in adjacent cleaning roller assemblies 3 are staggered vertically, the aluminum alloy foil 6 is positioned on the cleaning support roller 3.1. When the outer circumference of the aluminum alloy foil 6 is wrapped at a certain angle, the contact surface between the cleaning brush and the aluminum alloy foil 6 will become arc-shaped. When the arc angle of the arc-shaped contact surface is smaller than the wrap angle of the aluminum alloy foil 6 on the outer circumference of the cleaning support roller 3.1.2, the back of the contact surface between the aluminum alloy foil 6 and the cleaning brush is completely supported by the cleaning support roller 3.1.2. This completely solves the problem of easy breakage and strip breakage caused by the gap between the back of the contact surface between the aluminum alloy foil 6 and the cleaning brush when mechanically cleaned by the cleaning brush roller 3.1.1.

[0044] Preferably, the connection between the upper cleaning roller adjusting device 3.2.4 or the lower cleaning roller adjusting device 3.2.5 and the cleaning roller bearing seat 3.1.3 can also be a connecting bolt. The connecting bolt has threads with opposite directions at both ends. The connecting bolt connects the drive shaft of the upper cleaning roller adjusting device 3.2.4 to the cleaning roller bearing seat 3.1.3 and the telescopic output shaft of the lower cleaning roller adjusting device 3.2.5 to the cleaning roller bearing seat 3.1.3 through the threads with opposite directions at both ends. When using connecting bolts, lock nuts must be used to prevent the connecting bolts from loosening when the degreasing section of the aluminum alloy foil cleaning line is working.

[0045] The parts of this utility model not described in detail are existing technologies.
