[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This specific embodiment is a lithium electrode sheet recycling and filter press feeding device, the structural schematic diagram of which is shown below. Figures 1-6As shown, the machine includes a frame 1, a discharge roller 2, a drive mechanism 3, a dewatering roller 4, a left extrusion roller 5, a right extrusion roller 6, an upper flat belt roller group 7, and a lower flat belt roller group 8. A cover 101 is fixedly installed on the top of the frame 1. The cover 101 isolates the machine from the workshop, preventing material and water droplets from splashing and ensuring workshop cleanliness. Cover doors 102, made of glass, are installed on both the front and rear sides of the frame 1, providing isolation while allowing observation of the machine's operation. Electronic component covers 103 are installed on both the front and rear sides of the frame 1, below the cover doors 102, ensuring the electrical safety of the components. The discharge roller 2 includes an upper discharge roller rotatably mounted on the frame 1. The upper discharge roller 201 and the lower discharge roller 202 are rotatably mounted on the frame 1. The gap between the upper discharge roller 201 and the lower discharge roller 202 is the discharge port. The drive mechanism 3 is used to drive the discharge roller 2 to rotate. The dewatering roller 4 is rotatably mounted on the frame 1. The left extrusion roller 5 is rotatably mounted on the frame 1. The right extrusion roller 6 is rotatably mounted on the frame 1. When the drive mechanism 3 drives the discharge roller 2 to rotate, it can drive the upper flat belt roller group 7 and the lower flat belt roller group 8 to move. Thus, the aluminum electrode sheet first passes through the dewatering roller 4 for preliminary extrusion and dewatering, and then passes through the left extrusion roller 5 and the right extrusion roller 6 for secondary extrusion and dewatering before being discharged through the discharge roller 2. The feed port between the upper flat belt roller group 7 and the lower flat belt roller group 8 is funnel-shaped.

[0035] The dewatering roller 4 is a porous stainless steel roller, which allows for the rapid discharge of filtered water.

[0036] The drive mechanism 3 includes a drive motor 301 fixedly mounted on the top of the machine cover 101, a drive wheel 302 fixedly mounted on the output end of the drive motor 301, a driven wheel 303 fixedly mounted on one end of the upper discharge roller 201, an upper gear 304 fixedly mounted on the other end of the upper discharge roller 201, a lower gear 305 fixedly mounted on one end of the lower discharge roller 202, and a synchronous belt 306 that realizes the transmission connection between the drive wheel 302 and the driven wheel 303.

[0037] The lower gear 305 meshes with the upper gear 304. The upper discharge roller 201 is rotatably mounted on the upper bearing seat at the end positions near both ends, and the upper bearing seat is fixedly mounted on the frame 1. The other end of the lower discharge roller 202 and the position of the lower discharge roller 202 near the lower gear 305 are rotatably mounted on the lower bearing seat, and the lower bearing seat is fixedly mounted on the frame 1.

[0038] The drive motor 301 is started, driving the drive wheel 302 to rotate. During rotation, the drive wheel 302 drives the driven wheel 303 via the synchronous belt 306. The driven wheel 303, in turn, drives the upper discharge roller 201 to rotate. The upper discharge roller 201, in turn, drives the upper gear 304 to rotate. The upper gear 304, in turn, drives the lower gear 305, which meshes with it, to rotate. The lower gear 305, in turn, drives the lower discharge roller 202 to rotate. The upper discharge roller 302... During the rotation, the upper flat belt roller group 7 can be driven to rotate as a whole, and the lower discharge roller 202 can be driven to rotate as a whole. The electrode sheets placed at the trumpet-shaped inlet of the upper flat belt roller group 7 and the lower flat belt roller group 8 can follow the upper flat belt roller group 7 and the lower flat belt roller group 8 to first pass through the dewatering roller 4 for preliminary extrusion and dewatering, and then pass through the left extrusion roller 5 and the right extrusion roller 6 for secondary extrusion and dewatering, and then be discharged through the discharge port between the upper discharge roller 201 and the lower discharge roller 202.

[0039] The drive motor 301 is provided with a motor cover 307, which is fixedly installed on the machine cover 101. The motor cover 307 is used to protect the drive motor 301 from damage due to excessive humidity in the workshop.

[0040] The drive pulley 302, driven pulley 303 and timing belt 306 are all provided with the same housing 308. The housing 308 is fixedly installed on the frame 1. The housing 308 can prevent the drive pulley 302, driven pulley 303 and timing belt 306 from being exposed and causing safety accidents, and can also prevent the drive pulley 302 and driven pulley 303 from rusting due to excessive humidity.

[0041] The upper flat belt roller group 7 includes multiple upper roller shafts 701, upper correction rollers 702, and an upper flat belt 703 that drives the multiple upper roller shafts 701, upper correction rollers 702, upper discharge rollers 201, and right extrusion rollers 6. The upper roller shafts 701, upper correction rollers 702, left extrusion rollers 5, and right extrusion rollers 6 are all made of low-hardness PP material. This material selection can minimize the friction between the rollers and the upper flat belt 703, thereby meeting the drive combination of a single motor and synchronous belt 306. The upper flat belt 703 can be embedded in the extrusion to further filter the aluminum foil electrode. The upper flat belt 703 is made of polyurethane.

[0042] One of the upper roller shafts 701 has upper mounting blocks 707 rotatably mounted on both ends. A first upper sliding block 704 is fixedly mounted on the top of the upper mounting block 707. A first upper slide rail 705 is fixedly mounted on the top of the first upper sliding block 704. The first upper slide rail 705 is fixedly mounted on the frame 1. A first upper cylinder 706 that drives the first upper sliding block 704 to move is fixedly mounted on the frame 1. The first upper sliding block 704 is fixedly connected to the output end of the first upper cylinder 706.

[0043] When the tension of the upper flat belt 703 is insufficient, the first upper cylinder 706 is activated to drive the first upper sliding block 704 to move away from the drive motor 301. During the movement, the first upper sliding block 704 can drive the upper mounting block 707 to move away from the drive motor 301. During the movement, the upper mounting block 707 can drive one of the upper roller shafts 701 to move away from the drive motor 301. At the same time, the first upper sliding block 704 slides on the first upper slide rail 705. With the cooperation of the first upper sliding block 704 and the first upper slide rail 705, the movement of the upper mounting block 707 and one of the upper roller shafts 701 can be guided. The tension of the upper flat belt 703 can be adjusted by the movement of one of the upper roller shafts 701. Therefore, one of the upper roller shafts 701 is a tensioning roller and plays a tensioning role on the upper flat belt 703.

[0044] The remaining upper roller shafts 701 are rotatably mounted on the frame 1, and the frame 1 provides support for the upper roller shafts 701.

[0045] The lower flat belt roller assembly 8 includes multiple lower roller shafts 801, a lower correction roller 802, and a lower flat belt 803 that drives the multiple lower roller shafts 801, the lower correction roller 802, the lower discharge roller 202, and the right extrusion roller 6. The lower roller shafts 801, the lower correction roller 802, the left extrusion roller 5, and the right extrusion roller 6 are all made of low-hardness PP material. This material selection can minimize the friction between the rollers and the lower flat belt 803, thereby meeting the drive combination of a single motor and a synchronous belt 306. The lower flat belt 803 can be embedded in the extrusion to further filter the aluminum foil electrode. The lower flat belt 803 is made of polyurethane.

[0046] One of the lower roller shafts 801 has a lower mounting block 807 rotatably mounted on both ends. A first lower sliding block 804 is fixedly mounted on the top of the lower mounting block 807. A first lower sliding rail 805 is fixedly mounted on the bottom of the first lower sliding block 804. The first lower sliding rail 805 is fixedly mounted on the frame 1. A first lower cylinder 806 that drives the first lower sliding block 804 to move is fixedly mounted on the frame 1. The first lower sliding block 804 is fixedly connected to the output end of the first lower cylinder 806.

[0047] When the tension of the lower flat belt 803 is insufficient, the first lower cylinder 806 is activated to drive the first lower sliding block 804 to move away from the drive motor 301. During the movement, the first lower sliding block 804 can drive the lower mounting block 807 to move away from the drive motor 301. During the movement, the lower mounting block 807 can drive one of the lower roller shafts 801 to move away from the drive motor 301. At the same time, the first lower sliding block 804 slides on the first lower slide rail 805. With the cooperation of the first lower sliding block 804 and the first lower slide rail 805, the movement of the lower mounting block 807 and one of the lower roller shafts 801 can be guided. The tension of the lower flat belt 803 can be adjusted by the movement of one of the lower roller shafts 801. Therefore, one of the lower roller shafts 801 is a tensioning roller and plays a tensioning role on the lower flat belt 803.

[0048] The remaining lower roller shafts 801 are rotatably mounted on the frame 1, and the frame 1 provides support for the lower roller shafts 801.

[0049] The structure and correction principle of the upper correction roller 702 and the lower correction roller 802 are existing technologies and will not be described in detail here.

[0050] An upper scraper 9 is fixedly installed on the frame 1 at a position corresponding to the upper discharge roller 201, and a lower scraper 10 is fixedly installed on the frame 1 at a position corresponding to the lower discharge roller 202. Both the upper scraper 9 and the lower scraper 10 are made of PP material. The aluminum foil electrode sheet, which has been dehydrated by two extrusions, is discharged from the discharge port between the upper discharge roller 201 and the lower discharge roller 202. In order to prevent the aluminum foil from sticking to the upper flat belt 703 and the lower flat belt 803, the sticking aluminum foil is scraped off and discharged to reduce the wear on the upper flat belt 703 and the lower flat belt 803.

[0051] The frame 1 is fixedly equipped with two brackets 11, and baffles 12 are fixedly installed at the close ends of the two brackets 11. The baffles 12 are located at the feed inlets generated by the upper flat belt 703 and the lower flat belt 803. Since the lower flat belt 803 is horizontal at the feed inlet and the upper flat belt 703 is inclined at the feed inlet, the feed inlet is a funnel-shaped feed inlet. The funnel-shaped feed inlet can prevent the feed inlet from being blocked, which would prevent the aluminum foil electrode from being conveyed with the flat belt. At the same time, the baffles 12 can prevent the aluminum foil electrode from being deviated during feeding.

[0052] A liquid receiving tray 13 is fixedly installed on the frame 1 and directly below the lower flat belt 803. The liquid receiving tray 13 has a liquid receiving tray outlet 14 for the liquid filtered out of the liquid receiving tray 13. The liquid filtered out flows into the interior of the liquid receiving tray 13, and the liquid in the liquid receiving tray 13 can be collected and reused through the liquid receiving tray outlet 14.

[0053] This invention places the aluminum foil electrode sheet onto the lower flat belt 803. Under the limiting action of the baffle 12, the aluminum foil electrode sheet is guided to prevent it from deviating. The aluminum foil electrode sheet enters the feed inlet following the lower flat belt 803. Under the clamping of the upper flat belt 703 and the lower flat belt 803, the aluminum foil electrode sheet first passes through the dewatering roller 4 for preliminary extrusion and dewatering, and then passes through the left extrusion roller 5 and the right extrusion roller 6 for secondary extrusion and dewatering, before being discharged through the discharge roller 2. The entire process is a winding conveyor, which ensures the normal operation of the process. At the same time, the secondary extrusion and dewatering ensures the dewatering rate.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
