[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-6 This invention provides a cleaning mechanism for a copper foil production machine, including a worktable 1 on which copper foil 2 is conveyed. It also includes two cleaning components, respectively disposed on both sides of the copper foil 2, with the edges of the copper foil 2 located within the cleaning components. Each cleaning component includes a suction device 3, a water washer 4, and a dryer 5 arranged sequentially along the conveying direction of the copper foil 2. Two water processors 6 are respectively disposed on both sides of the worktable 1 and corresponding to the two cleaning components. Each water processor 6 has a central water injection chamber 601, with filter chambers 602 disposed on both sides of the central water injection chamber 601. The top and bottom ends of the central water injection chamber 601 are connected to the filter chambers 602. The air outlet of the suction device 3, the air outlet of the dryer 5, and the liquid outlet of the water washer 4 are connected to the central water injection chamber 601. A filter element is disposed within the filter chamber 602, with the liquid outlet of the filter element connected to the liquid inlet of the water washer 4.

[0031] Copper foil 2 is conveyed through workbench 1. The edges of the cut copper foil 2 pass through suction device 3. The negative pressure suction draws the powder on the surface of the copper foil 2 into the middle water injection chamber 601 to mix with water. The air disturbs the water in the middle water injection chamber 601, causing it to flow to the two filter chambers 602. In this process, on the one hand, it is convenient for air and water to mix, so that the powder is retained in the water. On the other hand, the water flow disturbance in the filter chamber 602 is small, so that large particles of powder settle in the filter chamber 602, which is convenient for powder collection.

[0032] After passing through the suction device 3, the copper foil 2 enters the water washing device 4 for rinsing. The rinsed water flows into the intermediate water injection chamber 601 and passes through the filter element in the filter chamber 602 to obtain fresh water. This fresh water is then introduced into the water washing device 4. This setup can reduce water consumption.

[0033] After the copper foil 2 is rinsed, it is dried by the dryer 5. The air obtained after drying is introduced into the intermediate water injection chamber 601 to heat the water in the water processor 6, so that the surface of the copper foil 2 is rinsed with water at a certain temperature, which facilitates subsequent drying.

[0034] Specifically, two supports 101 are fixedly connected to the top of the workbench 1, and a rotating roller 102 is rotatably connected to the supports 101. The copper foil 2 is conveyed through the rotating roller 102.

[0035] Further optimize the plan, referring to Figure 3 The water processor 6 includes a hollow processing box 603. Two partitions 604 are arranged opposite each other inside the processing box 603. The side walls of the two partitions 604 are fixed to the inner wall of the processing box 603. There is a gap between the top of the two partitions 604 and the inner wall of the top of the processing box 603, and there is a gap between the bottom of the two partitions 604 and the inner wall of the bottom of the processing box 603. The space between the two partitions 604 is a middle water injection chamber 601, and the space between the two partitions 604 and the inner wall of the side wall of the processing box 603 is a filter chamber 602.

[0036] Understandably, the air entering the intermediate water injection chamber 601 drives the water flow upward, and enters the filter chamber 602 through the gap between the top of the partition 604 and the inner wall of the top of the treatment tank 603. The water in the filter chamber 602 enters the intermediate water injection chamber 601 through the gap between the bottom of the partition 604 and the inner wall of the bottom of the treatment tank 603. During this process, heavier dust settles in the filter chamber 602, and the water in the filter chamber 602 is collected by the filter element for reuse.

[0037] Furthermore, the top of the processing box 603 is provided with an air outlet (not shown in the figure) to ensure that external gas can enter the processing box 603 normally and be discharged.

[0038] Furthermore, a wastewater drain pipe (not shown in the figure) is connected to the side wall of the treatment tank 603. The wastewater drain pipe is used to discharge the wastewater in the treatment tank 603. After a period of use, the water in the treatment tank 603 needs to be replaced.

[0039] Further optimize the plan, referring to Figure 3 The side wall of the workbench 1 is fixedly connected to a support plate 7. The bottom end of the processing box 603 is fixedly connected to the top end of the support plate 7. The bottom end of the processing box 603 is fixedly connected to a prism box 8, which passes through the support plate 7 and is fixedly connected to the support plate 7.

[0040] The prism box 8 is used to collect heavy dust particles, preventing the settled dust from being sprayed up again.

[0041] Further optimize the plan, referring to Figure 4 The suction device 3 includes a suction frame 301. A set of suction heads 302 are fixedly connected to the inner wall of the top and bottom of the suction frame 301 respectively. The copper foil 2 is located between the two sets of suction heads 302. The air outlet of the suction heads 302 is connected to the air collecting plate 303. The end of the air collecting plate 303 is connected to the air collecting pipe 304. The air collecting pipe 304 extends into the middle water injection chamber 601.

[0042] Understandably, to provide power to the suction head 302, external air enters the suction head 302 through the gap between the suction frame 301 and the copper foil 2, and at the same time, it carries the powder.

[0043] Specifically, the suction frame 301 is used to fix the suction head 302. The air collecting plate 303 and the air collecting pipe 304 can be rigid structures, that is, the suction frame 301 is supported by the air collecting plate 303 and the air collecting pipe 304, or other external support structures are set to achieve normal support for the suction frame 301.

[0044] Further optimize the plan, referring to Figure 3 A jet plate 9 is provided in the middle water injection chamber 601. The jet plate 9 is located at the bottom of the treatment box 603. The two side walls of the jet plate 9 are fixed to the side walls of the two partitions 604, and there is a gap between the two ends of the jet plate 9 and the inner wall of the treatment box 603. The air outlet of the air collection pipe 304 is connected to the air inlet of the jet plate 9.

[0045] In this configuration, the powder drawn by the suction head 302 enters the jet plate 9 through the gas collection pipe 304, and is evenly sprayed into the intermediate water injection chamber 601 by the jet plate 9, so that the gas is dispersed and the powder is dissolved in water.

[0046] Further optimize the plan, referring to Figure 5The water washer 4 includes a water washing box 401. A channel for the copper foil 2 to pass through is provided on the side of the water washing box 401 near the copper foil 2. A set of water washing heads 402 are fixed to the top and bottom of the water washing box 401, respectively. The inlet end of the water washing head 402 is connected to a filter element. The copper foil 2 is located between the two sets of water washing heads 402, and the side of the water washing box 401 is in contact with the surface of the copper foil 2. The outlet end of the water washing box 401 is connected to the intermediate water injection chamber 601. The two sets of water washing heads 402 on the water washing box 401 spray water onto the upper and lower surfaces of the copper foil 2 to remove residual powder. The wastewater is collected and introduced into the intermediate water injection chamber 601, where it is treated by the filter element and then used for cleaning again.

[0047] It should be noted that the side of the washing box 401 is in contact with the surface of the copper foil 2, that is, the copper foil 2 and the channel should be as compatible as possible to reduce the water flow out through the gap between the copper foil 2 and the channel.

[0048] In a further optimized design, a water collection box 403 is fixedly connected to the bottom of the washing box 401. A water collection channel 404 is provided on the inner wall of the bottom end of the washing box 401 near the water collection box 403. The water collection channel 404 is connected to the water collection box 403. A water guide pipe 405 is connected to the end of the water collection box 403. The water outlet of the water guide pipe 405 is connected to the top of the treatment tank 603 through the first water pump and is correspondingly set with the middle water injection chamber 601.

[0049] The water collection box 403 is used to collect wastewater. The wastewater is introduced into the water collection box 403 through the water collection channel 404, and then introduced into the intermediate water injection chamber 601 under the action of the water guide pipe 405 and the first water pump.

[0050] The design is further optimized. The filter element includes a filter cylinder 10 housed within the filter chamber 602. A water outlet pipe 11 is fixedly connected to the top of the filter cylinder 10, extending out from and fixedly connected to the top of the treatment tank 603. The outlet end of the water outlet pipe 11 is connected to two branch water outlet pipes 13 via a second water pump 12. The outlet ends of the two branch water outlet pipes 13 are respectively connected to two sets of water washing heads 402. The filter cylinder 10 is used to filter powder, ensuring that the powder remains within the treatment tank 603.

[0051] Further optimize the plan, referring to Figure 6 The dryer 5 includes a drying box 501. The copper foil 2 passes through the drying box 501. A set of drying heads 502 are fixed to the top and bottom of the drying box 501 respectively. The copper foil 2 is located between the two sets of drying heads 502. A hot air supply box 503 is fixed on the workbench 1. The air outlet of the hot air supply box 503 is connected to the two sets of drying heads 502 through the air guide pipe 504. An air outlet pipe 505 is connected to the side wall of the drying box 501. The air outlet of the air outlet pipe 505 is connected to the air inlet of the air jet plate 9.

[0052] Similarly, the contact between the drying box 501 and the copper foil 2 needs to be properly matched, such as the positional relationship between the washing box 401 and the copper foil 2, to minimize the escape of hot air, and to heat the water in the treatment box 603 by passing the dried hot air with a certain amount of moisture through the intermediate water injection cavity 601.

[0053] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
