[0075] 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.

[0076] Example:

[0077] like Figure 1 As shown, an embodiment of the present application discloses a membrane thinning device for performing multiple rolling on a membrane to thin it into a film. Its specific structure includes: a frame 1, a roller system 2, a transverse drive mechanism 3, multiple rotation drive mechanisms 4, several roller gap monitoring mechanisms 5 and several first roller gap adjustment mechanisms 6.

[0078] The rack 1 serves as a supporting structure for the equipment, ensuring that other components can work in a coordinated manner.

[0079] The roller system 2 is arranged in sequence in the transverse direction and is used for multiple roll ironing. It includes a movable support roller group 21, a fixed support roller group 22 and multiple working roller groups 23. The specific configuration is as follows:

[0080] The movable support roller group 21 is slidably connected to the frame 1 and can be displaced laterally to adjust the position of the working area to guide the input of the diaphragm;

[0081] The fixed support roller group 22 is fixedly connected to the frame 1 and is used to guide the film output;

[0082] A plurality of working roller groups 23 are arranged between the movable support roller group 21 and the fixed support roller group 22, and are slidably connected to the frame 1 and can be displaced laterally, and can cooperate to gradually thin the diaphragm.

[0083] The transverse driving mechanism 3 is installed on the frame 1 and is in transmission connection with the movable support roller group 21, and is used for driving the movable support roller group 21 to move transversely to achieve adjustment of the working area.

[0084] A plurality of rotary drive mechanisms 4 are mounted on the frame 1 and are in one-to-one correspondence with the working roller groups 23 and are transmission-connected to provide rotary power to each working roller group 23 to ensure that the diaphragm is uniformly thinned when passing through.

[0085] Several roll gap monitoring mechanisms 5 are provided on two adjacent working roll groups 23 in a one-to-one correspondence, and are used to monitor the size change of the roll gap in real time to ensure the accuracy and uniformity of the film thinning.

[0086] A plurality of first roll gap adjustment mechanisms 6 are provided on two adjacent working roll groups 23 in a one-to-one correspondence, and are used to adjust the roll gap size to meet the requirements of different film thinning thicknesses and ensure product quality.

[0087] It should be noted that the roller system 2 is arranged in the form of a movable support roller group 21, a first working roller group 23 to an nth working roller group 23, and a fixed support roller group 22, and the gap between two adjacent working roller groups 23 is gradually reduced in sequence, so that when the diaphragm is Figure 8 As shown, after multiple rolling processes of the roller system 2, the film is thinned to form a membrane. The rotation directions of two adjacent working roller groups 23 are opposite through the independent driving of several rotary drive mechanisms 4, thereby ensuring the smooth passage of the membrane.

[0088] The present invention can significantly shorten the length of the entire machine and simplify the rolling structure by providing a movable support roller group 21, several working roller groups 23 and a fixed support roller group 22 that are arranged in sequence laterally, thereby ensuring the continuity of electrode diaphragm preparation and improving production efficiency; the movable support roller group 21 is pushed to move laterally by the transverse driving mechanism 3, so as to cooperate with the fixed support roller group 22 so that the working roller groups 23 between the two are clamped and fixed, thereby ensuring the rolling effect of the diaphragm; the gap between the working roller groups 23 is adjusted by the first roller gap adjusting mechanism 6, and the gap size between the working roller groups 23 is monitored by the roller gap monitoring mechanism 5, thereby realizing closed-loop control of the roller gap and ensuring the versatility of the equipment, and having the advantages of simple operation, convenient adjustment, high control accuracy, etc., and good use effect.

[0089] In some embodiments, as Figure 1 As shown, the frame 1 includes: a base plate 11, a support frame 12 and two machine bases 13, which are specifically configured as follows:

[0090] The bottom plate 11 is arranged horizontally to provide stable support;

[0091] The support frame 12 is installed on the bottom surface of the base plate 11 to enhance stability and load-bearing capacity, and the height-adjustable foot pads on the legs ensure that the equipment is stably supported;

[0092] The two machine bases 13 are arranged parallel to each other and installed on the top surface of the base plate 11. The machine base 13 has a circular structure and has a receiving cavity 131 for installing the roller system 2. The receiving cavity 131 is dedicated to installing the roller system 2 to ensure stable operation of the roller system 2.

[0093] The above-mentioned arrangement realizes support at both ends of the roller system 2, enhances structural stability, ensures that the equipment is not prone to shaking or displacement during the thinning process of the diaphragm, and improves processing accuracy and safety; and the design of the base 13 with a circular structure not only provides sufficient installation space and protection for the roller system 2, but also optimizes the structural layout, making the connection between the components more compact and reasonable, thereby reducing the volume of the entire machine and facilitating the installation and maintenance of the equipment.

[0094] Based on the above embodiment, the movable support roller assembly 21 includes a movable support roller 211 and two first bearing seats 212 . The two first bearing seats 212 are rotatably mounted on both ends of the movable support roller 211 and are slidably mounted in the two accommodating cavities 131 .

[0095] In this embodiment, the fixed support roller group 22 includes a fixed support roller (not shown in the figure) and two second bearing seats 221. The two second bearing seats 221 are respectively rotatably installed at both ends of the fixed support roller and are respectively fixedly installed in the two accommodating cavities 131.

[0096] In this embodiment, if Figure 2 and Figure 6 As shown, the working roll group 23 includes a working roll 231 and two third bearing seats 232 . The two third bearing seats 232 are rotatably mounted on both ends of the working roll 231 and are slidably mounted in the two accommodating cavities 131 .

[0097] For example, in order to improve versatility, the rotating connection structures of the movable support roller group 21, the fixed support roller group 22 and the working roller group 23 are the same; Figure 5 As shown, taking the movable support roller group 21 as an example, two precision cylindrical bearings or tapered roller bearings are installed in one first bearing seat 212, and two precision cylindrical bearings or tapered roller bearings and a ball bearing are installed in the other first bearing seat 212; the two first bearing seats 212 and the bearings therein are respectively mounted on both sides of the movable support roller 211, and are used to bear the weight of the movable support roller 211 and support the operation of the movable support roller 211, and the ball bearings therein are used for axial positioning; and since the operation of the bearings requires lubricating grease, lubricating grease needs to be added to the first bearing seats 212, and in order to prevent the bearings from detaching and the lubricating grease from leaking, an inner seal and an outer seal are respectively arranged on both sides of each first bearing seat 212.

[0098] Through the above-mentioned separation design of the bearing seat and the roller shaft, the roller shaft can be stably supported and rotate smoothly, and can also be laterally displaced according to production needs to adapt to diaphragms of different thicknesses. This ensures the stability and precision of the diaphragm during the processing and improves the flexibility of equipment adjustment.

[0099] In some embodiments, as Figure 1As shown, the transverse driving mechanism 3 includes: two hydraulic cylinders 31 , which are transversely installed on the inner wall of the accommodating cavity 131 in a one-to-one correspondence, and the piston rods are connected to the adjacent first bearing seats 212 .

[0100] Specifically, the hydraulic cylinder 31 is connected to an external hydraulic control system, which includes an accumulator. The hydraulic control system controls the extension of the piston rod to apply pressure to the adjacent first bearing seat 212. After the pressure value is reached, the piston rod stops extending and the accumulator maintains the oil circuit pressure to ensure the stability of the applied pressure.

[0101] Through the above-mentioned setting, pressure can be applied stably, which improves the operating stability of the equipment, improves the accuracy and uniformity of diaphragm thinning, and ensures product quality.

[0102] In some embodiments, as Figure 2 and Figure 7 As shown, the first roll gap adjustment mechanism 6 includes two roll gap adjustment units 61, which are symmetrically arranged in two accommodating chambers 131 and located between two adjacent third bearing seats 232. This arrangement ensures the consistency of the roll gap size and uniform force through adjustment at both ends, thereby improving operational stability and product quality.

[0103] Specifically, if Figure 4 and Figure 7 As shown, each roll gap adjustment unit 61 includes a movable wedge 611, a fixed wedge 612 and a drive unit 613, which are arranged as follows:

[0104] The movable wedge 611 is vertically slidably mounted on a side wall of a third bearing seat 232;

[0105] The fixed wedge 612 is fixedly mounted on the side wall of the other third bearing seat 232 and corresponds to the movable wedge 611. The inclinations of the contact surfaces of the movable wedge 611 and the fixed wedge 612 match.

[0106] The driving unit 613 and the moving wedge block 611 are installed together on the same third bearing seat 232, and the output end is transmission-connected to the moving wedge block 611 for driving the moving wedge block 611 to move up and down.

[0107] Preferably, the driving unit 613 may be an electric actuator, a servo cylinder or other components, without limitation.

[0108] For example, if it is necessary to enlarge the roll gap between two adjacent working roll groups 23, the hydraulic cylinder 31 is kept in a depressurized state, and the telescopic rods of the drive units 613 in the two roll gap adjustment units 61 in the corresponding first roll gap adjustment mechanism 6 are controlled to extend, so that the telescopic rods drive the movable wedge 611 to move downward. Since the contact surface of the movable wedge 611 and the fixed wedge 612 is an inclined surface with a certain slope, the up and down displacement of the movable wedge 611 can be converted into a left and right thickness difference, so that the gap between the third bearing seat 232 of the two working roll groups 23 is continuously enlarged to Δt, and at the same time, the piston of the hydraulic cylinder 31 is continuously pressed into the cylinder body Δt through the transmission of the force of several roll groups. At the same time, the roll gap monitoring mechanism 5 continuously feeds back the change value corresponding to the roll gap to the control system until the control system receives the feedback value of Δt from the roll gap monitoring mechanism 5, at which time the drive unit 613 stops extending, and the control system controls the hydraulic system to make the hydraulic cylinder 31 apply pressure to each roll group and use the accumulator to maintain the pressure.

[0109] Through the above-mentioned setting, the gap between two adjacent working rollers 231 can be adjusted with high precision, thereby ensuring the thickness consistency of the diaphragm. The equipment has high operability and can realize automatic adjustment, thereby improving production efficiency and production stability, and ensuring product quality. It also has the characteristics of simple and compact structure, which is convenient for installation, layout, inspection and maintenance.

[0110] In some embodiments, as Figure 2 and Figure 7 As shown, the roll gap monitoring mechanism 5 includes: two roll gap monitoring units 51, which are symmetrically arranged in the two accommodating cavities 131 and provided between two adjacent third bearing seats 232; this arrangement ensures the consistency of the roll gap size at both ends by monitoring at both ends, thereby improving the operation stability and product quality.

[0111] Specifically, if Figure 4 and Figure 7 As shown, each roll gap monitoring unit 51 includes: a contact block 511, a mounting seat 512 and a displacement sensor 513, which are arranged as follows:

[0112] The contact block 511 is mounted on a third bearing seat 232;

[0113] The mounting seat 512 is mounted on another third bearing seat 232;

[0114] The displacement sensor 513 is mounted on the mounting base 512 , and the measuring head corresponds to the contact block 511 .

[0115] During measurement, when the measuring head of the displacement sensor 513 touches the contact block 511, as the contact block 511 moves back and forth, the displacement sensor 513 will feedback the displacements L1 and L2, and the difference ΔL=L1-L2 is obtained by calculation. The size of the displacement difference ΔL is the size of the roller gap.

[0116] Through the above arrangement, the roller gap can be monitored with high precision, ensuring the adjustment effect, and it has the advantages of simple structure, easy disassembly and assembly, and convenient maintenance and repair.

[0117] In some embodiments, as Figure 1 As shown, the rotary drive mechanism 4 includes: a power base 41, a reducer 42, a drive motor 43 and a coupling 44, which are arranged as follows:

[0118] The power base 41 is mounted on the top surface of the base plate 11 and is used to support and fix other components;

[0119] The speed reducer 42 is mounted on the power base 41 and is used to reduce the rotation speed and increase the torque;

[0120] The output end of the drive motor 43 is connected to the input end of the reducer 42 to provide rotational power;

[0121] One end of the coupling 44 is connected to the driving end of the reducer 42, and the other end is connected to the working roll 231, which is used to achieve smooth and uninterrupted transmission of rotational power. It can also compensate for axial, radial and angular displacements caused by factors such as roll gap adjustment, installation errors, and working deformation, thereby ensuring the stable operation of the transmission system.

[0122] The design of the rotary drive mechanism 4 has significant effects such as efficient power transmission, precise control, strong adaptability and long service life, thereby improving the overall performance and reliability of the equipment.

[0123] In some embodiments, as Figure 1 As shown, it also includes: two linear sliding mechanisms 7, which are symmetrically arranged in the two accommodating cavities 131, so as to ensure the smoothness and stability of the sliding of each roller group by limiting the two ends and reduce the probability of jamming.

[0124] Specifically, each linear sliding mechanism 7 includes: a linear guide rail 71 and multiple linear bearings 72; wherein, the linear guide rail 71 is installed at the bottom of the accommodating cavity 131; multiple linear bearings 72 are slidably installed on the linear guide rail 71, and are installed one by one at the bottom of the first bearing seat 212, the second bearing seat 221 and the third bearing seat 232.

[0125] Through the above arrangement, the accuracy and stability of the lateral sliding of each bearing seat are improved, and a higher load-bearing capacity is achieved, thereby ensuring the stable operation of the mechanical equipment.

[0126] In some embodiments, as Figure 2 As shown, it also includes: a second roll gap adjustment mechanism 8, which is provided between the dynamic support roll group 21 and the adjacent working roll group 23, and is used to adjust the roll gap between the two.

[0127] For example, in order to improve the versatility of parts, the arrangement of the second roller gap adjustment mechanism 8 is the same as that of the first roller gap adjustment mechanism 6 described above, so its specific structure is not repeated; but it is not limited to this, and can also be other forms, without specific limitation.

[0128] Through the above arrangement, the diaphragm can be rolled once between the movable support roller set 21 and the working roller set 23, thereby increasing the number of thinning rolling times of the equipment and improving the use effect.

[0129] In some embodiments, as Figure 6 As shown, a circulating oil circuit 2311 is provided in the working roll 231. The working roll group 23 further includes: a transmission flange 233, a rotary joint 234 and a stop frame 235, which are arranged as follows:

[0130] The transmission flange 233 is mounted on one end of the working roll 231 and is used to connect with the coupling 44 to facilitate assembly and disassembly and improve the stability of the connection;

[0131] The rotary joint 234 is installed at the other end of the working roll 231 and is connected to the circulating oil circuit 2311 to transport the heat exchange medium and avoid interference with the rotation.

[0132] The stop frame 235 is installed between the rotary joint 234 and the adjacent third bearing seat 232 to limit the rotation of the rotary joint 234.

[0133] Specifically, the circulating oil circuit 2311 has a connecting port at one end of the working roll 231, and a partition pipeline is installed through the connecting port to divide the circulating oil circuit 2311 into two parts: a liquid inlet channel and a liquid outlet channel; the rotary joint 234 has a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are respectively connected to the liquid inlet channel and the liquid outlet channel, so that the heat exchange medium can circulate in the working roll 231, thereby heating or cooling the heat exchange medium through the temperature control system to control the temperature of the working roll 231.

[0134] Through the above arrangement, the transmission stability is ensured, and the temperature of each working roller 231 can be independently controlled, thereby improving the temperature control accuracy, ensuring the rolling effect, and avoiding the occurrence of roller sticking, breakage, etc.
