[0063] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0065] In this application, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0066] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0067] Example:

[0068] like Figures 1 to 5 As shown, an embodiment of the present application discloses a vertical roller press for roller-pressing and thinning processing of positive electrode sheets with high solid content, and its specific structure includes: a base 1, two working rollers 2 and two supporting mechanisms 3.

[0069] The base 1 serves as the supporting foundation for the entire device and is used to install and fix other components. A support frame is preferably provided at the bottom thereof to increase the counterweight and improve the operating stability of the device. A plurality of height-adjusting pads are provided at the bottom of the support frame to ensure that the base 1 can be set horizontally.

[0070] The two working rollers 2 are arranged side by side up and down, including an upper pressing roller 2a and a lower pressing roller 2b, which cooperate with each other to complete the rolling process of the material.

[0071] The two supporting mechanisms 3 are arranged opposite to each other and are used to support the working roll 2 at both ends to prevent it from shaking or deflecting during operation, thereby enhancing the stability of the structure and ensuring smooth operation.

[0072] Specifically, if Figure 3 As shown, each supporting mechanism 3 includes a wall panel 31 , two bearing seats 32 , a driving cylinder 33 and a gap adjustment assembly 34 .

[0073] The wall panel 31 is arranged on the base 1 and has a accommodating groove 311 on the side thereof for supporting and fixing other components in the supporting mechanism 3 .

[0074] The two bearing seats 32 include an upper seat 32a and a lower seat 32b, each equipped with bearings to reduce friction and wear on the work rolls 2 during rotation. The upper seat 32a is fixedly mounted within the receiving slot 311 and rotatably connected to the end of the upper pressure roller 2a, providing support for the upper pressure roller 2a. The lower seat 32b is slidably mounted within the receiving slot 311 and rotatably connected to the end of the lower pressure roller 2b, supporting the lower pressure roller 2b and allowing it to move up and down under the action of the drive cylinder 33.

[0075] The driving cylinder 33 is installed in the accommodating groove 311, and the output end is transmission-connected with the lower shaft seat 32b. The driving cylinder 33 is a hydraulic cylinder or a pneumatic cylinder, and is used to drive the lower shaft seat 32b to move up and down.

[0076] The gap adjustment assembly 34 includes an upper wedge 341, a lower wedge 342 and a drive unit 343. Figure 4 As shown, the upper wedge block 341 is slidably set on the bottom surface of the upper shaft seat 32a and can move horizontally; the lower wedge block 342 is fixedly set on the top surface of the lower shaft seat 32b and corresponds to the upper wedge block 341.

[0077] The driving unit 343 is installed on the wall panel 31, and the output end is connected to the upper wedge block 341 for driving the upper wedge block 341 to move horizontally; and the inclination of the contact surface of the upper wedge block 341 and the lower wedge block 342 is matched to ensure that the two can fit fully.

[0078] In the above technical solution, the gap adjustment method is as follows:

[0079] First, in the gap adjustment assembly 34, the upper wedge block 341 is driven horizontally by the driving unit 343. Since the contact surface between the upper wedge block 341 and the lower wedge block 342 is an inclined surface with a certain slope, the horizontal displacement of the upper wedge block 341 can be converted into a vertical height difference, thereby achieving the gap definition between the upper pressure roller 2a and the lower pressure roller 2b.

[0080] Then, the lower shaft seat 32b is pushed up by the driving cylinder 33 until the lower wedge block 342 and the upper wedge block 341 are kept in close contact, which is used to stabilize the gap between the upper pressure roller 2a and the lower pressure roller 2b, thereby achieving adjustable gap.

[0081] This utility model uses a drive unit 343 to drive the upper wedge 341 horizontally. The upper wedge 341 and the lower wedge 342 cooperate to convert the horizontal displacement of the upper wedge 341 into a vertical height difference, thereby defining the gap. The upward movement of the drive cylinder 33 stabilizes the gap size, achieving high-precision adjustment of the gap between the two rollers and ensuring the thickness consistency of the battery electrode sheets. The device also offers high operability and automated adjustment, thereby improving production efficiency and stability and ensuring product quality. Furthermore, the vertical structural design shifts the direction of pressure application to vertical, effectively avoiding the problem of material stratification. Its compact structure better accommodates the spatial layout requirements of modern factories.

[0082] In some implementations, such as Figure 4 As shown, the drive unit 343 includes: a screw 3431, a reducer 3432 and a servo motor 3433, which are specifically configured as follows:

[0083] The screw rod 3431 is horizontally arranged in the accommodating groove 311 and is threadedly connected to the upper wedge block 341, and is used to drive the upper wedge block 341 to move linearly by rotation;

[0084] The reducer 3432 is mounted on the wall panel 31, and its output end is in driving connection with one end of the screw rod 3431, so as to reduce the output speed of the servo motor 3433 and increase the torque, thereby smoothly driving the screw rod 3431 to rotate;

[0085] The driving end of the servo motor 3433 is connected to the input end of the reducer 3432 for providing a precisely controllable power source to drive the screw 3431 to achieve precise rotational motion.

[0086] The above-mentioned design of the driving unit 343 has the advantages of high-precision control, high torque output, smooth operation and easy maintenance, which significantly improves the controllability of the gap adjustment.

[0087] In some embodiments, as Figure 2 、 Figure 3 and Figure 7 As shown, it also includes: two rotary joints 4, which are installed one-to-one at one end of the working roll 2; and a cooling water channel 321 is provided inside the bearing seat 32, and an internal circulation oil circuit 21 is provided inside the working roll 2, which corresponds one-to-one to and is connected to the rotary joints 4.

[0088] When in use, the cooling water channel 321 is connected in series to the water cooling system, so that the cooling water circulates through the inside of the bearing seat 32, thereby cooling the bearing seat 32; and the rotary joint 4 is connected in series to the hot oil supply system, so that the heat-conducting oil circulates through the inside of the working roll 2 through the rotary joint 4 and the internal circulation oil circuit 21, thereby continuously transferring heat to the surface of the working roll 2, and due to the setting of the rotary joint 4, it will not interfere with the rotation of the working roll 2.

[0089] Through the above-mentioned arrangement, the bearing seat 32 can be efficiently cooled, thereby avoiding deterioration of the lubricating oil, improving the operating stability and service life of the bearing, and thereby ensuring the long-term stable operation of the equipment; it can also ensure that the ambient temperature during the pole piece rolling process is constant, ensure the consistency of the rolling quality, and improve the electrochemical performance, mechanical stability and safety of the battery.

[0090] In some embodiments, as Figure 5 As shown, the support mechanism 3 further includes: two positioning components 35, which correspond one-to-one to the bearing seats 32, and are used to ensure that the upper pressing roller 2a and the lower pressing roller 2b can be aligned up and down after assembly.

[0091] Specifically, each positioning assembly 35 includes a fixed plate 351, a movable plate 352 and a plurality of bolts 353, which are arranged as follows:

[0092] The fixing plate 351 is installed on one side of the inner wall of the receiving groove 311 and fits closely with the bearing seat 32;

[0093] The movable plate 352 is arranged on the other side of the inner wall of the accommodating groove 311;

[0094] A plurality of bolts 353 are laterally inserted into the wall panel 31 and threadedly connected to the wall panel 31 . The bolts 353 extend into the receiving slots 311 and abut against the movable plate 352 .

[0095] When in use, tighten the bolt 353 so that it extends further into the accommodating groove 311, thereby pushing the movable plate 352, so that the bearing seat 32 is clamped between the fixed plate 351 and the movable plate 352; and since the fixed plate 351 remains fixed, the upper pressure roller 2a and the lower pressure roller 2b can remain aligned up and down.

[0096] Through the above arrangement, it is ensured that the assembled upper pressing roller 2a and the lower pressing roller 2b are aligned up and down, thereby ensuring the rolling effect. In addition, the structure is simple, the operation is convenient, and it is convenient for actual production use.

[0097] In some embodiments, as Figure 1 and Figure 5 As shown, it also includes: two roller assemblies 5 and a fine-tuning roller assembly 6, which are specifically configured as follows:

[0098] Two roller assemblies 5 are installed between the two wall panels 31 and are arranged on both sides of the working roller 2. The height of the roller shaft can be adjusted up and down to ensure that the electrode sheet passes through the gap between 2a and 2b in a horizontal posture, thereby improving the rolling effect.

[0099] The fine-tuning roller assembly 6 is installed on two wall panels 31 and arranged on one side of the working roller 2. The height of its roller shaft can be adjusted up and down, which is used for guiding and tensioning the pole piece after rolling, ensuring that the pole piece after rolling can stably enter the next process.

[0100] When using, Figure 5 As shown, the pole piece is guided by the roller assembly 5 on the left and enters the gap between the upper pressure roller 2a and the lower pressure roller 2b, and after being thinned into a sheet, it moves along the forward route to the roller assembly 5 on the right, and then guided by the roller assembly 5 on the right and moves downward to be tangent to the fine-tuning roller assembly 6. During the process, appropriate tension is ensured, and finally it is guided and tensioned by the fine-tuning roller assembly 6 to enter the next process.

[0101] Through the above arrangement, it is possible to ensure that the electrode sheet is rolled in a horizontal posture with appropriate tension, thereby improving the rolling stability and enhancing the product quality.

[0102] In some embodiments, the support mechanism 3 includes: two sets of limit plates 36 , which are installed on the outside of the wall panel 31 and correspond to and fit the bearing seats 32 one by one.

[0103] Exemplarily, each set of limiting plates 36 has two pieces, and are symmetrically arranged on both sides of the bearing seat 32, which reduces stress concentration and improves structural stability.

[0104] By providing the limiting plate 36 , the bearing seat 32 can be axially limited, ensuring that the upper shaft seat 32a and the lower shaft seat 32b can be aligned at both ends, and realizing the sliding installation of the lower shaft seat 32b.

[0105] In some embodiments, it further includes: a transmission mechanism 7, which is installed on the base 1 and is in transmission connection with the two working rollers 2, and is used to drive the two working rollers 2 to synchronously move at the same speed and in opposite directions.

[0106] Based on the above embodiment, Figure 1 and Figure 2 As shown, the transmission mechanism 7 includes a power support base 71 and two transmission assemblies 72. The power support base 71 is mounted on the base 1 to provide support; the two transmission assemblies 72 are arranged side by side and mounted on the power support base 71, and are in one-to-one correspondence with the work rolls 2 and are transmission-connected.

[0107] By providing two transmission assemblies 72, the two working rolls 2 can be driven to rotate respectively, which has the advantage of being easy to produce, assemble, overhaul and maintain.

[0108] In this embodiment, the transmission assembly 72 includes: a planetary reducer 721, a drive motor 722 and a coupling 723, and its specific functions and connection methods are as follows:

[0109] The planetary reducer 721 is installed on the power support seat 71 and is responsible for receiving and reducing the power speed from the driving source, while increasing the output torque to meet the rotational power characteristics required by the work roll 2;

[0110] The output end of the driving motor 722 is connected to the input end of the planetary reducer 721 for outputting stable power;

[0111] One end of the coupling 723 is connected to the driving end of the planetary reducer 721, and the other end is connected to the end of the working roll 2. It ensures the smooth and uninterrupted transmission of power, and can also compensate to a certain extent for axial, radial and angular displacements caused by factors such as installation errors and working deformation, thereby ensuring the stable operation of the transmission system.

[0112] The design of the transmission assembly 72 has the remarkable effects of efficient power transmission, precise control, strong adaptability and long service life, thereby improving the overall performance and reliability of the equipment.

[0113] In some embodiments, a suspension rod 8 is further included, which is horizontally arranged and installed on the top ends of the two wall panels 31 for suspension when assembling the upper pressing roller 2a and the lower pressing roller 2b.
