[0036] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0037] like Figure 1-3 As shown, a battery pole piece scrap compression device comprises:

[0038] Rack 1;

[0039] A pressing cavity 2, wherein a feeding cavity and an extrusion cavity are sequentially arranged in the length direction of the pressing cavity 2, wherein the feeding cavity is connected with the extrusion cavity, wherein a discharge port 21 is arranged on the extrusion cavity, an extrusion port is arranged on the feeding cavity, and a feeding port 22 connected with the feeding cavity is also arranged above the pressing cavity 2;

[0040] The discharge gate mechanism 4 is disposed at the discharge port 21 of the pressing cavity 2, and the discharge gate mechanism 4 is suitable for opening and closing the discharge port 21 of the pressing cavity 2;

[0041] The punching mechanism 3 is mounted on the frame 1 and is provided with a compression punch 31. The punching mechanism 3 is adapted to drive the compression punch 31 to move from the extrusion port to the discharge port 21 when the discharge port gate mechanism 4 closes the discharge port 21 of the pressing cavity 2, so as to extrude the material in the extrusion cavity.

[0042] The cleaning scraper assembly 5 includes a driving member 51 fixed on the frame 1 and a scraper 53 installed on the driving member 51 . The driving member 51 is suitable for driving the scraper 53 to clean the compression punch 31 .

[0043] In this embodiment, if Figure 1 and Figure 3As shown, the battery pole piece scraps are used as materials, which are first put into the feed port 22 of the pressing cavity 2, and then enter the feed cavity. At this time, the discharge port gate mechanism 4 is started to close the discharge port 21, and then the stamping mechanism 3 is started. The stamping mechanism 3 drives the compression punch 31 to push the material from the feed cavity to the extrusion cavity from the extrusion port, and the material is effectively compressed in the extrusion cavity. After the compression is completed, the discharge port gate mechanism 4 is started again to open the discharge port 21, and the stamping mechanism 3 continues to push the compressed material out of the discharge port 21 through the compression punch 31. After the compression punch 31 completes the pushing, it retracts to the position of the cleaning scraper assembly 5. At this time, the drive member 51 is started to drive the scraper 53 to descend to clean the compression punch 31, ensuring the cleanliness of the stamping mechanism 3, which can extend the service life of the equipment and reduce maintenance costs.

[0044] Specifically, Figure 1 As shown, the battery pole piece scrap compression device also includes a feed port opening and closing mechanism 6 , which is disposed at the feed port of the pressing cavity 2 , and is suitable for opening or closing the feed port 22 .

[0045] Specifically, Figure 1-2 As shown, the feed port opening and closing mechanism 6 may be of the following structure, including:

[0046] A feed inlet movable plate 61, the feed inlet movable plate 61 is hinged to one side of the feed inlet 22 of the pressing chamber 2;

[0047] A driving mechanism bracket 62, the driving mechanism bracket 62 is fixed on the frame 1;

[0048] The feed inlet movable plate driving mechanism 63 has a middle part hinged on the driving mechanism bracket 62, a telescopic driving end is provided on the feed inlet movable plate driving mechanism 63, and the driving end of the feed inlet movable plate driving mechanism 63 is hinged to the feed inlet movable plate 61. The feed inlet movable plate driving mechanism 63 is suitable for driving the feed inlet movable plate 61 to rotate around the hinge point to open and close the feed inlet 22.

[0049] Specifically, Figure 1-2 As shown, the feed port movable plate driving mechanism 63 is a telescopic cylinder.

[0050] In this embodiment, if Figure 1-2 As shown, the function of the feed port opening and closing mechanism 6 is to facilitate the opening and closing of the feed port. When in use, the feed port movable plate driving mechanism 63 first drives the feed port movable plate 61 to rotate and open the feed port 22, and then the battery pole piece scraps are loaded into the feed cavity through the feed port 22. After the loading is completed, the feed port movable plate driving mechanism 63 drives the feed port movable plate 61 to rotate and close the feed port 22 to prevent the material from overflowing from the feed port during the compression process.

[0051] The feed port movable plate driving mechanism 63 adopts the form of a telescopic cylinder, which has the advantages of simple structure and high reliability. Of course, other forms of linear actuators, such as electric push rods, etc., can also be adopted.

[0052] The function of the driving mechanism bracket 62 is to provide fixed support for the feed port movable plate driving mechanism 63 to ensure that it can work reliably. The structural form of the bracket 62 can be designed according to the specific installation space.

[0053] Specifically, Figure 1-3 As shown, the stamping mechanism 3 may have the following structure, including:

[0054] The stamping drive mechanism 32 is installed on the frame 1. The stamping drive mechanism 32 is provided with a stamping drive end, on which a compression punch 31 is installed. The stamping drive mechanism 32 is suitable for driving the compression punch 31 to move along the feed cavity of the pressing cavity 2 toward the extrusion cavity.

[0055] Specifically, Figure 2 As shown, the punching drive mechanism 32 is a hydraulic cylinder.

[0056] In this embodiment, if Figure 1-3 As shown, the function of the punching mechanism 3 is to squeeze the battery pole piece scraps in the feeding cavity into the extrusion cavity and compress them.

[0057] When in use, the battery pole piece scraps to be compressed are first loaded into the feed cavity, and then the punch drive mechanism 32 drives the compression punch 31 to move along the feed cavity toward the extrusion cavity, compressing the battery pole piece scraps in the feed cavity and squeezing them into the extrusion cavity.

[0058] The use of a hydraulic cylinder as the punching drive mechanism 32 can provide a sufficiently large driving force to ensure that the battery pole piece scraps are reliably compressed and smoothly squeezed into the extrusion cavity. The hydraulic cylinder is small in size, has a large output torque, and responds quickly, and is an ideal linear actuator.

[0059] The structural shape of the compression punch 31 should match the shape of the feed cavity and the extrusion cavity to obtain the best compression and extrusion effect. The compression punch 31 can be made of metal material, and a protective layer can be installed on the surface to extend the service life.

[0060] In addition to the hydraulic cylinder, the stamping drive mechanism 32 may also be in other forms, such as a screw drive mechanism, a chain drive mechanism, etc., as long as it can provide sufficient linear driving force.

[0061] In addition, a displacement sensor, a pressure sensor, etc. may be provided on the punching drive mechanism 32 to monitor and control the displacement and pressure of the compression punch 31 .

[0062] Specifically, Figure 3As shown, the battery pole piece scrap compression device also includes a compression punch sliding guide mechanism, which is suitable for guiding the compression punch 31 to slide back and forth along the feed cavity to the extrusion cavity;

[0063] The compression punch sliding guide mechanism may have the following structure, including:

[0064] A sliding seat 71, the sliding seat 71 is connected to the compression punch 31;

[0065] Four rollers 72 are rotatably mounted on the sliding seat 71 , and the rollers 72 are suitable for supporting the sliding seat 71 to slide along the feeding cavity.

[0066] In this embodiment, if Figure 1-3 As shown, the function of the compression punch sliding guide mechanism is to ensure that the compression punch 31 slides along a straight line during the compression and extrusion process to avoid deviation or jamming, thereby ensuring the smooth progress of the compression and extrusion process.

[0067] The compression punch sliding guide mechanism adopts the design of a sliding seat 71 and a roller 72. The sliding seat 71 is fixedly connected to the compression punch 31, and the roller 72 is installed on the sliding seat 71. When the compression punch 31 makes a linear reciprocating motion, the roller 72 can roll on the pressing cavity 2, so that the sliding seat 71 and the compression punch 31 can slide smoothly along the straight line, reducing the movement resistance and wear.

[0068] The number of rollers 72 can be set according to specific needs. In this embodiment, four rollers are used to improve support stability. The material of the rollers 72 can be selected from wear-resistant alloys to extend the service life.

[0069] In addition to the roller sliding mode, a slider sliding mode can also be adopted, that is, a slider is arranged on the sliding seat 71, and the slider is used in conjunction with the linear slide rail of the pressing cavity 2. This mode has slightly greater resistance, but a relatively simple structure.

[0070] In addition, a limit mechanism may be provided on the sliding seat 71 to limit the maximum stroke of the compression punch 31 to prevent the punch from moving too far and damaging the device.

[0071] Specifically, Figure 1-2 As shown, the discharge port gate mechanism 4 includes:

[0072] The gate mounting frame 41 is fixed on the frame 1 and is located above the discharge port 21 of the pressing chamber 2;

[0073] A gate plate 43, the gate plate 43 is arranged in the gate plate mounting frame 41;

[0074] The gate lifting drive source 44 is fixed on the gate mounting frame 41. The gate lifting drive source 44 is provided with a lifting drive end, which is connected to the gate 43. The gate lifting drive source 44 is suitable for driving the gate 43 to move up and down to open and close the discharge port 21 of the pressing cavity 2.

[0075] Specifically, Figure 1-2 As shown, a guide rail is also installed on the gate mounting frame 41, and the gate 43 is suitable for moving up and down along the guide rail.

[0076] In this embodiment, if Figure 1-3 As shown, the function of the discharge port gate mechanism 4 is to control the opening and closing of the discharge port 21 of the pressing cavity 2, thereby controlling the timing of the compressed battery electrode scraps being discharged from the extrusion cavity.

[0077] The gate mounting frame 41 is fixed on the frame to provide support and guidance for the movement of the gate 43. The gate 43 is mounted in the gate mounting frame 41 and can move up and down by the drive of the gate lifting drive source 44, thereby opening or closing the discharge port 21.

[0078] The gate lifting drive source 44 can be a cylinder, an electric push rod or other linear actuator. The selection of the drive source needs to be determined according to the required driving force and response speed. The drive end can be connected to the gate 43 by a hinge or a direct rigid connection.

[0079] In order to ensure the smooth movement of the gate plate 43 when opening and closing, a guide rail is provided on the gate plate mounting frame 41, and the gate plate 43 slides up and down along the guide rail. This design can prevent the gate plate 43 from tilting or getting stuck during movement.

[0080] A sealing device, such as a rubber sealing strip, is also provided on the gate plate 43, and a limit device is provided when the gate is opened, so as to further improve the sealing performance and reliability.

[0081] The battery pole piece scrap compression device also has a position sensor, which monitors the position of the compression punch 31 and the gate plate 43 and provides a feedback signal for control.

[0082] A displacement sensor may be installed on the compression punch 31 or the sliding seat 71 to directly measure the displacement of the compression punch 31. A proximity switch may also be installed at an appropriate position in the pressing cavity 2 to indirectly obtain the position of the compression punch 31 by detecting the in-position signal of the compression punch 31.

[0083] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
