Description

Technical Field

[0001] The present application relates to the field of power rollers, and more particularly to a roller drive mechanism for an extraction tank. Background Art

[0002] As a key component, the diaphragm plays a crucial role in wet lithium batteries. The production process of wet lithium battery diaphragms requires multiple steps, and each step requires strict quality control and precise process parameter settings to ensure the performance and quality of the final product. Among them, the extraction section is also a key process for diaphragm pore formation.

[0003] Previously, the production line speed was slow, and the width was below 5m. Idle rollers could be used for the guide rollers in the extraction tank. However, with the increase in production line speed and the width of the film surface, the use of idle rollers would cause scratches on the film surface. Summary of the Utility Model

[0004] In order to reduce the possibility of scratches on the film surface during use and improve product quality, the present application provides a roller drive mechanism for an extraction tank.

[0005] A roller drive mechanism for an extraction tank provided by the present application adopts the following technical solutions:

[0006] A roller drive mechanism for an extraction tank includes an active end side plate, a passive end side plate, and a roller body. An active end bearing seat is provided on the active end side plate, and a passive end bearing seat is provided on the passive end side plate. One end of the roller body is provided with an active end bushing, and the other end is provided with a passive end bushing. A first bearing is sleeved and fixed on the passive end bushing, and a second bearing is sleeved and fixed on the active end bushing. The outer ring of the first bearing is slidably installed axially in the passive end bearing seat, and the outer ring of the second bearing is fixedly installed in the active end bearing seat. A drive source is provided on the active end side plate, and the output end of the drive source is connected to the active end bushing.

[0007] By adopting the above technical solution, the roller body is rotatably installed on the active end side plate and the passive end side plate. When the drive source rotates, it drives the active end bushing to rotate, and the rotation of the active end bushing drives the roller body to rotate. Compared with the non-powered roller, it can reduce the possibility of film surface scratching caused by slipping between the film surface and the roller surface, thereby improving the product quality. In addition, one roller body is independently controlled by one drive source, and the speed of two adjacent roller bodies can be adjusted to regulate the tension of the drawn film, so as to facilitate the control of certain physical properties of the diaphragm. In this application, both the inner and outer rings of the second bearing are fixed, while the inner ring of the first bearing is fixed and the outer ring can axially move in the passive end bushing. In this way, on the one hand, it can compensate for the cumulative error and processing error of the installation, avoid the generation of large axial forces on the first bearing and the second bearing, and reduce the service life; on the other hand, since the roller body is relatively long and the thermal expansion and contraction of metal are inevitable, the deformations generated by the thermal expansion and contraction of the roller body can be accommodated through the movable design of the first bearing, which is beneficial to improving the applicability and service life of the transmission mechanism.

[0008] Optionally, an end cover is detachably fixed on the passive end side plate. A first positioning ring is provided on the inner side of the end cover, and a first mounting hole for inserting the first positioning ring is provided on the passive end side plate. The passive end bearing seat includes two mutually spliced first half bearing seats, and one of the first half bearing seats is detachably fixed to the first positioning ring.

[0009] By adopting the above technical solution, the passive end bearing seat can be formed by splicing two first half bearing seats, which is convenient for the installation of the first bearing and is beneficial to improving the disassembly and assembly efficiency during the maintenance of the roller body.

[0010] Optionally, an axial retaining cover is provided at one end of the active end bearing seat close to the passive end bearing seat, and the axial retaining cover abuts against the outer ring of the second bearing.

[0011] By adopting the above technical solution, the axial position of the second bearing is limited by the axial retaining cover, so as to ensure that the axial distance between the active end bushing and the drive source remains unchanged, and further ensure the transmission stability of the transmission mechanism.

[0012] Optionally, an end plate is detachably fixed on the active end side plate. A second positioning ring is provided on the inner side of the end plate, and a second mounting hole for inserting the second positioning ring is provided on the active end side plate. The active end bearing seat includes two mutually spliced second half bearing seats, and one of the second half bearing seats is detachably fixed to the second positioning ring.

[0013] By adopting the above technical solution, the active end bearing seat can be formed by splicing two second half bearing seats, which is convenient for the installation of the second bearing and is beneficial to further improving the disassembly and assembly efficiency during the maintenance of the roller body.

[0014] Optionally, the axial retaining cover includes two semi-ring retaining covers, and the two semi-ring retaining covers are respectively detachably connected to the two second semi-bearing seats in a one-to-one correspondence, and both of the two semi-ring retaining covers are in contact with the outer ring of the second bearing.

[0015] By adopting the above technical solution, the installation of the axial retaining cover is facilitated.

[0016] Optionally, an installation bracket is provided on the end plate, the drive source includes a servo motor and a speed reducer connected to the servo motor, the speed reducer is arranged on the installation bracket, and the output end of the speed reducer is connected to the driving end shaft sleeve.

[0017] By adopting the above technical solution, after the speed reducer amplifies the output torque of the servo motor, it is transmitted to the driving end shaft sleeve, improving the driving ability of the drive source, and being beneficial to adapting to a larger load and avoiding damage to the servo motor due to overload.

[0018] Optionally, a magnetic coupling is provided on the end plate, the outer rotor of the magnetic coupling is connected to the output end of the speed reducer, and the inner rotor of the magnetic coupling is connected to the driving end shaft sleeve.

[0019] By adopting the above technical solution, the magnetic coupling in the present application is an embedded structure, different from the traditional head-to-head structure of the coupling. Using the magnetic coupling for transmission is beneficial to reducing the axial force and improving the service life of the transmission mechanism; in addition, since the solvent in the extraction section during diaphragm production is dichloromethane, which is very harmful to personnel, using the magnetic coupling for transmission can completely achieve static sealing, which is beneficial to reducing the risk of leakage.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. In the present application, the roller body is rotatably installed on the driving end side plate and the passive end side plate. When the drive source rotates, it drives the driving end shaft sleeve to rotate, and the driving end shaft sleeve rotates to drive the roller body to rotate. Compared with the roller without power, it can reduce the possibility of film surface scratching caused by slipping between the film surface and the roller surface, thereby improving the product quality. In addition, one roller body is independently controlled by one drive source, and the speed of two adjacent roller bodies can be adjusted to adjust the film pulling tension, so as to control certain physical properties of the diaphragm.

[0022] 2. In the present application, both the inner and outer rings of the second bearing are fixed, while the inner ring of the first bearing is fixed and the outer ring can axially float in the passive end shaft sleeve. In this way, on the one hand, it can compensate for the cumulative error and processing error of the installation, and avoid the generation of a large axial force on the first bearing and the second bearing, thereby reducing the service life; on the other hand, since the roller body is relatively long and the thermal expansion and contraction of metal are inevitable, the floating design of the first bearing can accommodate the deformation amount of the roller body caused by thermal expansion and contraction, which is beneficial to improving the applicability and service life of the transmission mechanism.

[0023] 3. The magnetic coupling in this application has an embedded structure, which is different from the traditional coupling structure where the coupling heads meet head-on. Using the magnetic coupling for transmission is beneficial to reducing the axial force and improving the service life of the transmission mechanism. In addition, since the solvent in the extraction section during diaphragm production is dichloromethane, which is highly harmful to personnel, using the magnetic coupling for transmission can completely achieve static sealing, which is beneficial to reducing the risk of leakage.

Detailed Description of the Embodiment

[0029] The following will further elaborate on this application in conjunction with the attached Figures 1-4 , and make a more detailed description of this application.

[0030] Embodiment:

[0031] The embodiment of this application discloses a roller drive mechanism for an extraction tank. Refer to Figures 1-2, An extraction tank roller drive mechanism, including an active end side plate 1, a passive end side plate 2 and a roller body 3.

One end of the roller body 3 is coaxially fixed with an active end bushing 31 by means of a snap ring connection, and the other end is coaxially fixed with a passive end bushing 32 by means of a snap ring connection. A first bearing 321 is sleeved and fixed on the passive end bushing 32, and a second bearing 311 is sleeved and fixed on the active end bushing 31.

A drive source 6 is provided on the active end side plate 1, and the output end of the drive source 6 is connected to the active end bushing 31.

[0032] In this embodiment, the roller body 3 is rotatably installed on the active end side plate 1 and the passive end side plate 2. When the drive source 6 rotates, it drives the active end bushing 31 to rotate, and the rotation of the active end bushing 31 drives the roller body 3 to rotate. Compared with a roller without power, it can reduce the possibility of film surface scratching caused by slipping between the film surface and the roller surface, thereby improving product quality. In addition, one roller body 3 is independently controlled by one drive source 6, and the speed of two adjacent roller bodies 3 can be adjusted to regulate the tension of the drawn film, so as to control certain physical properties of the diaphragm.

[0033] In this application, both the inner and outer rings of the second bearing 311 are fixed, while the inner ring of the first bearing 321 is fixed and the outer ring can axially move in the passive end bushing 32. In this way, on the one hand, it can compensate for the cumulative error and machining error of the installation, and avoid the generation of large axial forces on the first bearing 321 and the second bearing 311, thus reducing the service life; on the other hand, since the roller body 3 is relatively long and the thermal expansion and contraction of metal are inevitable, the deformations caused by the thermal expansion and contraction of the roller body 3 can be accommodated through the movable design of the first bearing 321, which is beneficial to improving the applicability and service life of the drive mechanism.

[0034] Refer to Figures 2-3 , A end cover 21 is detachably fixed on the passive end side plate 2 by means of bolt connection. A first positioning ring 211 is fixed on the inner side of the end cover 21, and a first installation hole 22 for inserting the first positioning ring 211 is opened on the passive end side plate 2. The passive end bearing seat 5 includes two mutually spliced first half bearing seats 51, and one of the first half bearing seats 51 is detachably fixed to the first positioning ring 211 by means of bolt connection. In this way, the passive end bearing seat 5 can be formed by splicing the two first half bearing seats 51, which is convenient for the installation of the first bearing 321 and is beneficial to improving the disassembly and assembly efficiency during the maintenance of the roller body 3.

[0035] Refer to Figures 2-4, an axial retaining cover 7 is installed at one end of the driving end bearing seat 4 close to the driven end bearing seat 5, and the axial retaining cover 7 abuts against the outer ring of the second bearing 311. In this way, the second bearing 311 is axially limited by the axial retaining cover 7, so as to ensure that the axial distance between the driving end bushing 31 and the drive source 6 remains unchanged, and further ensure the transmission stability of the transmission mechanism.

[0036] Refer to Figures 2-4 , a end plate 11 is detachably fixed on the driving end side plate 1 by means of bolt connection. A second positioning ring 111 is fixed on the inner side of the end plate 11, and a second mounting hole 12 for inserting the second positioning ring 111 is formed on the driving end side plate 1. The driving end bearing seat 4 includes two second half bearing seats 41 that are spliced together, and one of the second half bearing seats 41 is detachably fixed to the second positioning ring 111 by means of bolt connection. In this way, the driving end bearing seat 4 can be formed by splicing the two second half bearing seats 41, which is convenient for the installation of the second bearing 311 and is beneficial to further improve the disassembly and assembly efficiency during the maintenance of the roller body 3.

[0037] In this embodiment, both the driving end bearing seat 4 and the driven end bearing seat 4 are split structures, and the two first half bearing seats 51 and the two second half bearing seats 41 are respectively fastened and spliced by means of bolt connection.

[0038] Refer to Figure 2 and Figure 4 , for the convenience of installing the axial retaining cover 7, the axial retaining cover 7 includes two half-ring retaining covers 71. The two half-ring retaining covers 71 respectively correspond to the two second half bearing seats 41 and are detachably fixed by means of bolt connection. Both of the two half-ring retaining covers 71 abut against the outer ring of the second bearing 311.

[0039] Refer to Figure 2 and Figure 4 , a mounting bracket 112 is fixed on the outer side of the end plate 11 by means of bolt connection. The drive source 6 includes a servo motor 61 and a speed reducer 62 connected to the servo motor 61. The speed reducer 62 is installed on the mounting bracket 112, and the output end of the speed reducer 62 is connected to the driving end bushing 31. In this way, after the speed reducer 62 amplifies the output torque of the servo motor 61, it is transmitted to the driving end bushing 31, thereby improving the driving ability of the drive source 6 and being beneficial to adapting to a larger load to avoid damage to the servo motor 61 due to overload.

[0040] Refer to Figure 2 and Figure 4, a magnetic coupling 113 is also installed on the outer side of the end plate 11, and the outer rotor of the magnetic coupling 113 is coaxially connected to the output end of the speed reducer 62 by means of a keyway connection, and the inner rotor of the magnetic coupling 113 is coaxially connected to the driving end bushing 31 by means of a keyway connection. The magnetic coupling 113 in this application is an embedded structure, which is different from the traditional structure where the coupling heads meet head-to-head. Using the magnetic coupling 113 for transmission is beneficial to reducing the axial force and improving the service life of the transmission mechanism; in addition, since the solvent in the extraction section during diaphragm production is dichloromethane, which is very harmful to personnel, using the magnetic coupling 113 for transmission can completely achieve static sealing and is beneficial to reducing the risk of leakage.

Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
