[0002] This application is based on and claims priority to Chinese Patent Application No. 202520138739.2, filed on January 21, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of battery manufacturing technology, and in particular to a support mechanism and a rolling mill. Background Technology

[0004] In related technologies, batteries are widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. The battery electrode assembly mainly consists of electrode sheets. During the production process of battery electrode sheets, the coated electrode sheets are typically compacted using rollers in a rolling mill.

[0005] The rolls of a roller pressing machine are supported by a support mechanism. These rolls wear down over time, directly affecting the uniformity of electrode thickness. Therefore, regular roll replacement is necessary in production. However, in existing roller pressing machines, the process of removing and installing the support plate during roll replacement is time-consuming, impacting production efficiency. Therefore, how to efficiently perform roll replacement operations is a problem that needs to be solved. Summary of the Invention

[0006] This application provides a support mechanism and a rolling mill device. The support mechanism can reduce the time spent disassembling and assembling the support pad during the roll replacement process, which is beneficial to improving production efficiency.

[0007] In a first aspect, this application provides a support mechanism, comprising: a bearing housing for mounting and supporting a roll; a support pad detachably disposed on the bottom surface of the bearing housing, the support pad including a pad and a magnetic module disposed on the pad, the magnetic module including a magnetic module body and an adjusting member, the adjusting member being disposed on the magnetic module body for adjusting the magnetic strength of the magnetic module body; a support cylinder located below the bearing housing and including a cylinder body and a piston, the piston being movably disposed on the cylinder body, the support pad being located between the upper end face of the piston and the bottom surface of the bearing housing, the support cylinder supporting the bearing housing via the support pad; wherein the magnetic module has a first state and a second state, the magnetic strength of the magnetic module in the first state being greater than that in the second state, when the magnetic module is in the first state, the magnetic module is used to fix the support pad to the bearing housing by the magnetic attraction between the magnetic module and the bearing housing, and when the magnetic module is in the second state, the support pad is detachable from the bearing housing.

[0008] In the above technical solution, by setting a magnetic module on the pad and having two states with different magnetic strengths, the magnetic strength of the magnetic module can be adjusted as needed. For example, when the roller pressing equipment is working normally, the magnetic strength of the magnetic module is increased to put the magnetic module in the first state. In this case, the magnetic attraction between the support pad and the bearing seat is large, thereby attracting and fixing the support pad to the bearing seat through the magnetic attraction between the magnetic module and the bearing seat. When it is necessary to replace the roll, the magnetic strength of the magnetic module can be decreased to put the magnetic module in the second state. In this case, the magnetic attraction between the support pad and the bearing seat is small or non-existent, and the support pad... The roller can be separated from the bearing housing, allowing for easy removal of the roller along with the bearing housing for subsequent roller replacement. After the roller is replaced, when installing the roller along with the bearing housing onto the support cylinder, the magnetism of the magnetic module can be increased to put the magnetic module in its first state. This results in a stronger magnetic attraction between the support pad and the bearing housing, allowing the support pad to automatically adhere and fix itself to the bottom surface of the bearing housing under the magnetic attraction. By setting up the magnetic module and adjusting its magnetism, the installation and separation of the support pad and the bearing housing can be easily achieved, reducing the time spent disassembling and assembling the support pad during roller replacement and improving production efficiency.

[0009] In some embodiments, the magnetic module is detachably connected to the pad.

[0010] In the above technical solution, by making the magnetic module and the pad detachable, the maintenance and replacement of the magnetic module are convenient, which helps to extend the service life of the entire magnetic module.

[0011] In some embodiments, the magnetic module is connected to the pad by fasteners.

[0012] In the above technical solution, by connecting the magnetic module and the pad with fasteners, the connection between the magnetic module and the pad can be made more reliable and stable, reducing the risk of the magnetic module falling off the pad.

[0013] In some embodiments, the magnetic module is disposed on the outer periphery of the pad.

[0014] In the above technical solution, by setting the magnetic suction module on the outer periphery of the pad, it is convenient to adjust the magnetic suction module; and it does not affect the flatness of the upper surface of the pad, so that the upper surface of the pad can contact the bottom surface of the bearing seat, so that there is a large contact area between the pad and the bearing seat, which makes the support cylinder support the bearing seat more stable and reliable through the support pad, and thus the support of the roll more stable and reliable.

[0015] In some embodiments, the magnetic module body extends circumferentially along the pad.

[0016] In the above technical solution, by extending the magnetic module body along the circumference of the pad, the magnetic attraction area between the magnetic module and the bearing seat can be larger, thereby allowing the support pad to be more stably attracted and fixed on the bearing seat through the magnetic module.

[0017] In some embodiments, the upper surface of the magnetic module is flush with the upper surface of the pad; or, the upper surface of the magnetic module is lower than the upper surface of the pad.

[0018] In the above technical solution, by ensuring that the upper surface of the magnetic module is not higher than the upper surface of the pad, when the magnetic module is attached to and fixed to the bottom surface of the bearing seat, the upper surface of the pad can contact the bottom surface of the bearing seat, thereby creating a large contact area between the support pad and the bearing seat. This allows the support cylinder to provide more stable and reliable support to the bearing seat through the support pad, thus providing more stable and reliable support to the roll.

[0019] In some embodiments, there are multiple magnetic modules, and the multiple magnetic modules are arranged at intervals along the circumference of the pad.

[0020] In the above technical solution, by setting multiple magnetic modules spaced apart along the circumference of the pad, the magnetic attraction between the support pad and the bearing seat can be increased, and the magnetic attraction between the support pad and the bearing seat can be distributed more evenly. This makes the support cylinder support the bearing seat more stable and reliable through the support pad, thereby making the support of the roll more stable and reliable.

[0021] In some embodiments, there are two magnetic modules, which are located on opposite sides of the pad.

[0022] In the above technical solution, by setting two magnetic suction modules and placing them on opposite sides of the pad, the number of magnetic suction modules can be moderate, the magnetic attraction between the support pad and the bearing seat can be large, and the magnetic attraction between the support pad and the bearing seat can be evenly distributed. This makes the support cylinder support the bearing seat more stable and reliable through the support pad, thereby making the support of the roll more stable and reliable.

[0023] In some embodiments, the magnetic module body includes a magnetic base and a permanent magnet. The magnetic base includes two sub-magnetic bases and a partition plate. The sub-magnetic bases are magnetically conductive, and the partition plate is a non-magnetically conductive component. The two sub-magnetic bases are arranged horizontally, and the partition plate is sandwiched between the two sub-magnetic bases. The two sub-magnetic bases and the partition plate together define a receiving cavity. The permanent magnet is disposed in the receiving cavity. The adjusting component is connected to the permanent magnet to drive the permanent magnet to move between a first position and a second position. When the permanent magnet is in the first position, the N and S poles of the permanent magnet are arranged along a first direction and opposite to the partition plate, and the magnetic module is in the first state. When the permanent magnet is in the second position, the N and S poles of the permanent magnet are arranged along a second direction and opposite to the sub-magnetic bases, and the magnetic module is in the second state. The angle between the second direction and the vertical direction is greater than the angle between the first direction and the vertical direction.

[0024] In the above technical solution, the magnetic attraction module is configured to include a permanent magnet and a magnetic base, and the magnetic base is configured to include two sub-magnetic bases and a partition plate sandwiched between the two sub-magnetic bases. The partition plate is configured as a non-magnetic component and the two sub-magnetic bases are configured as magnetic components. The partition plate can isolate the two sub-magnetic bases from magnetic interference. The permanent magnet is placed in the cavity defined by the magnetic base. By connecting the adjustment component to the permanent magnet, the permanent magnet can be driven to move between a first position and a second position. When the permanent magnet is in different positions, the magnetic attraction module displays different magnetic strengths, thereby making it easy to adjust the magnetic strength of the magnetic attraction module. This also makes the structure of the magnetic attraction module simple and easy to adjust and control.

[0025] In some embodiments, the angle between the first direction and the vertical direction is 0 to 10°, and the angle between the second direction and the vertical direction is 80° to 90°.

[0026] In the above technical solution, when the magnetic module is in the first state, the angle between the orientation of the N and S poles of the permanent magnet and the vertical direction is small or parallel to the vertical direction. This allows the N and S poles of the permanent magnet to be directly opposite the partition plate of the magnetic base, resulting in a larger overall magnetic field of the magnetic module and a stronger magnetic attraction between the magnetic module and the bearing seat. When the magnetic module is in the second state, the angle between the orientation of the N and S poles of the permanent magnet and the vertical direction is large. This allows the N and S poles of the permanent magnet to be directly opposite the sub-magnetic base of the magnetic base and offset from the partition plate by a large angle, resulting in a smaller or no overall magnetic field of the magnetic module and a smaller or no magnetic attraction between the magnetic module and the bearing seat, thus facilitating the separation of the support pad and the bearing seat.

[0027] In some embodiments, the adjusting member is rotatably disposed on the magnetic base and connected to the middle of the permanent magnet to drive the permanent magnet to rotate.

[0028] In the above technical solution, by rotatably setting the adjusting member on the magnetic base and connecting it to the middle of the permanent magnet, the permanent magnet can be rotated around the middle by rotating the adjusting member, thereby conveniently realizing the movement of the permanent magnet driven by the adjusting member to switch the state of the magnetic attraction module.

[0029] In some embodiments, the magnetic module is disposed on the outer periphery of the pad, and the adjusting member is mounted on one side of the magnetic base along the circumferential direction of the pad.

[0030] In the above technical solution, by setting the magnetic suction module on the outer periphery of the pad, it is convenient to adjust the magnetic suction module; and it does not affect the flatness of the upper surface of the pad, so that the upper surface of the pad can contact the bottom surface of the bearing seat, resulting in a large contact area between the pad and the bearing seat. This allows the support cylinder to provide more stable and reliable support to the bearing seat through the support pad, thereby providing more stable and reliable support to the roll; and by installing the adjusting component on one side of the magnetic base along the circumferential direction of the pad, it is convenient to operate the adjusting component.

[0031] In some embodiments, the upper end face of the piston contacts the lower surface of the support pad to support the support pad and the bearing seat. When the magnetic module is in the second state, the support cylinder is used to hold the support pad.

[0032] In the above technical solution, the upper end face of the piston contacts the lower surface of the support pad to support the support pad and the bearing seat. Since there is no connection between the support cylinder and the support pad, only a contact support relationship, the matching of the support cylinder and the support pad is more flexible. Support cylinders or support pads of different specifications and sizes can be selected as needed. Furthermore, when the magnetic module is in the second state, the support pad is separated from the bearing seat and supported by the support cylinder, which facilitates the placement of the support pad after separation from the bearing seat. No additional manual labor or additional structure is required to support the support pad during the disassembly and assembly of the support pad, making the disassembly and assembly process of the pad relatively simple.

[0033] In some embodiments, a positioning post is provided on one of the upper surface of the pad and the bottom surface of the bearing seat, and a positioning hole is provided on the other of the upper surface of the pad and the bottom surface of the bearing seat, and the positioning post is inserted into the positioning hole in the vertical direction.

[0034] In the above technical solution, by setting a positioning post on one of the pad and the bearing housing and a positioning hole on the other, when the support pad is adsorbed and fixed to the bearing housing, the installation position of the support pad can be quickly positioned by inserting the positioning post into the positioning hole, thus avoiding uneven force caused by arbitrary changes in the position of the support pad.

[0035] In a second aspect, this application provides a rolling mill device, comprising: a support mechanism according to the first aspect of this application; and a roll, the roll being mounted on the bearing housing via a bearing.

[0036] In the above technical solution, by setting up the support mechanism, the time for disassembling and assembling the support pad during the roll replacement process can be reduced, which is beneficial to improving production efficiency.

[0037] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0052] In this application, "multiple" means two or more (including two).

[0053] In related technologies, batteries are widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. The battery electrode assembly mainly consists of electrode sheets. During the production process of battery electrode sheets, the coated electrode sheets are typically compacted using rollers in a rolling mill.

[0054] The rolls of a roller pressing machine are supported by a support mechanism. These rolls wear down over time, directly affecting the uniformity of electrode thickness. Therefore, regular roll replacement is necessary in production. However, in existing roller pressing machines, the process of removing and installing the support plate during roll replacement is time-consuming, impacting production efficiency. Therefore, how to efficiently perform roll replacement operations is a problem that needs to be solved.

[0055] Based on this, the applicant proposes a support mechanism, including: a bearing housing, a support pad, and a support cylinder. The bearing housing is used to install and support the roll. The support pad is detachably disposed on the bottom surface of the bearing housing. The support pad includes a pad and a magnetic module disposed on the pad. The magnetic module includes a magnetic module body and an adjusting component. The adjusting component is disposed on the magnetic module body and is used to adjust the magnetic strength of the magnetic module body. The support cylinder is located below the bearing housing and includes a cylinder body and a piston. The piston is disposed on the cylinder body and can move up and down. The support pad is located between the upper end face of the piston and the bottom surface of the bearing housing. The support cylinder supports the bearing housing through the support pad. The magnetic module has a first state and a second state with different magnetic strengths. The magnetic strength of the magnetic module in the first state is greater than that in the second state. When the magnetic module is in the first state, it is used to fix the support pad to the bearing housing through the magnetic attraction between the magnetic module and the bearing housing. When the magnetic module is in the second state, the support pad can be separated from the bearing housing.

[0056] The aforementioned support mechanism incorporates a magnetic module on the support plate, with two states exhibiting different magnetic strengths. This allows for adjustment of the magnetic strength as needed. For instance, during normal operation of the rolling mill, the magnetic strength is increased to the first state, resulting in a stronger magnetic attraction between the support plate and the bearing housing. This magnetic attraction effectively holds the support plate firmly onto the bearing housing. When the roll needs to be replaced, the magnetic strength is decreased to the second state, where the magnetic attraction between the support plate and the bearing housing is weaker or nonexistent. The roller can be separated from the bearing housing, allowing for easy removal of the roller along with the bearing housing for subsequent roller replacement. After the roller is replaced, when installing the roller along with the bearing housing onto the support cylinder, the magnetism of the magnetic module can be increased to put the magnetic module in its first state. This results in a stronger magnetic attraction between the support pad and the bearing housing, allowing the support pad to automatically adhere and fix itself to the bottom surface of the bearing housing under the magnetic attraction. By setting up the magnetic module and adjusting its magnetism, the installation and separation of the support pad and the bearing housing can be easily achieved, reducing the time spent disassembling and assembling the support pad during roller replacement and improving production efficiency.

[0057] The support mechanism 200 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0058] Referring to Figures 1-2, in a first aspect, this application provides a support mechanism 200, including: a bearing seat 40, a support pad 100, and a support cylinder 30. The bearing seat 40 is used to install and support a roll. The support pad 100 is detachably disposed on the bottom surface of the bearing seat 40. The support pad 100 includes a pad 10 and a magnetic module 20 disposed on the pad 10. The magnetic module 20 includes a magnetic module body 21 and an adjusting member 22. The adjusting member 22 is disposed on the magnetic module body 21 and is used to adjust the magnetic strength of the magnetic module body 21. The support cylinder 30 is located below the bearing seat 40 and includes a cylinder body 31 and a piston 32. The piston 32 is movable up and down on the cylinder 31. The support pad 100 is located between the upper end face of the piston 32 and the bottom face of the bearing seat 40. The support cylinder 30 supports the bearing seat 40 through the support pad 100. The magnetic module 20 has a first state and a second state with different magnetic strengths. The magnetic strength of the magnetic module 20 in the first state is greater than that in the second state. When the magnetic module 20 is in the first state, it is used to fix the support pad 100 to the bearing seat 40 through the magnetic attraction between the magnetic module 20 and the bearing seat 40. When the magnetic module 20 is in the second state, the support pad 100 can be separated from the bearing seat 40.

[0059] The roll can be used for roll coating of the electrode sheet. For example, the roll can be rotatably mounted on the bearing seat 40, and the roll can be fitted with a bearing. The roll can be mounted on the bearing seat 40 through the bearing, and the bearing seat 40 can be used to support the roll.

[0060] The support cylinder 30 can be a hydraulic cylinder, which drives the piston 32 to move up and down through hydraulic oil. The up and down movement of the piston 32 facilitates the separation of the support cylinder 30 from the bearing seat 40, and can also adjust the height position of the bearing seat 40, thereby adjusting the height position of the roll.

[0061] When the roller pressing equipment is working normally, the support pad 100 can increase the contact area between the support cylinder 30 and the bearing seat 40, thereby enabling the bearing seat 40 to be stably and reliably supported by the support cylinder 30. For example, the projection of the upper end face of the piston 32 on the horizontal plane is located within the projection of the pad 10 on the horizontal plane, and the projected area of ​​the pad 10 on the horizontal plane is larger than the projected area of ​​the upper end face of the piston 32 on the horizontal plane.

[0062] The magnetic strength of the magnetic module 20 can be changed by manually adjusting the adjusting component 22 or by using a tool. For example, when the magnetic module 20 is in the first state, the magnetic force displayed by the magnetic module 20 is relatively large, and the magnetic attraction between the magnetic module 20 and the bearing seat 40 can be greater than the weight of the magnetic module 20 itself; when the magnetic module 20 is in the second state, the magnetic force displayed by the magnetic module 20 is relatively small or non-magnetic, and the magnetic attraction between the magnetic module 20 and the bearing seat 40 can be less than the weight of the magnetic module 20 itself.

[0063] At least a portion of the bottom of the bearing housing 40 is made of a magnetic material, or at least a portion of the bottom of the bearing housing 40 is made of steel or iron. Thus, in the second state, the magnetic module 20 and the bearing housing 40 can have a magnetic attraction force to attract and fix the support pad 100 to the bearing housing 40. For example, the bottom of the bearing housing 40 may be made of a magnetic material, or the entire bottom of the bearing housing 40 may be made of a magnetic material.

[0064] The following is a brief description of the roll replacement process: When the roll is worn and needs to be replaced, the magnetic force of the magnetic module 20 is reduced by adjusting the adjusting component 22 so that the magnetic module 20 is in the second state. In this way, the magnetic attraction between the support pad 100 and the bearing seat 40 is small or non-existent. For example, the support pad 100 can be separated from the bearing seat 40 at this time. The roll can then be removed together with the bearing seat 40 for easy replacement. After the roll is replaced, when the roll and bearing seat 40 are installed above the support cylinder 30, the magnetic force of the magnetic module 20 can be increased by adjusting the adjusting component 22 so that the magnetic module 20 is in the first state. In this way, the magnetic attraction between the support pad 100 and the bearing seat 40 is large, and the support pad 100 can be automatically attracted and fixed to the bottom surface of the bearing seat 40 under the action of the magnetic attraction.

[0065] For example, compared to fixing the pad 10 to the bearing seat 40 with fasteners, the support mechanism 200 and the rolling equipment in this embodiment of the application do not require loosening or tightening the fasteners in a confined space during the replacement and disassembly of the pad 10. Loosening or tightening the fasteners in a confined space is not only difficult but also time-consuming. This application uses the magnetic attraction between the magnetic module 20 and the bearing seat 40 to fix the support pad 100 to the bearing seat 40. By adjusting the adjusting member 22, the support plate can be separated from the bearing seat 40, which is simple to operate and takes less time.

[0066] In the above technical solution, by setting a magnetic module 20 on the pad 10 and making the magnetic module 20 have two states with different magnetic strengths, the magnetic strength of the magnetic module 20 can be adjusted as needed. For example, when the roller pressing equipment is working normally, the magnetic strength of the magnetic module 20 is increased so that the magnetic module 20 is in the first state. In this way, the magnetic attraction between the support pad 100 and the bearing seat 40 is large, and the support pad 100 is attracted and fixed to the bearing seat 40 by the magnetic attraction between the magnetic module 20 and the bearing seat 40. When it is necessary to replace the roll, the magnetic strength of the magnetic module 20 can be decreased so that the magnetic module 20 is in the second state. In this way, the magnetic attraction between the support pad 100 and the bearing seat 40 is small or there is no magnetic attraction. The support plate 100 can be separated from the bearing housing 40. At this time, the roller can be removed together with the bearing housing 40 for easy replacement of the roller. After the roller is replaced, when installing the roller together with the bearing housing 40 above the support cylinder 30, the magnetism of the magnetic module 20 can be increased to make the magnetic module 20 in the first state. In this way, the magnetic attraction between the support plate 100 and the bearing housing 40 is large, and the support plate 100 can be automatically attracted and fixed to the bottom surface of the bearing housing 40 under the action of magnetic attraction. By setting the magnetic module 20 and adjusting the magnetism of the magnetic module 20, the installation and separation between the support plate 100 and the bearing housing 40 can be easily realized, which can reduce the time for disassembling and assembling the support plate 100 during the roller replacement process and improve production efficiency.

[0067] In some embodiments, the magnetic module 20 is detachably connected to the pad 10.

[0068] In the above technical solution, by making the magnetic module 20 and the pad 10 detachably connected, it is convenient to maintain and replace the magnetic module 20, which helps to extend the service life of the entire magnetic module 20.

[0069] In some embodiments, the magnetic module 20 is connected to the pad 10 by fasteners.

[0070] In the above technical solution, by connecting the magnetic module 20 and the pad 10 with fasteners, the connection between the magnetic module 20 and the pad 10 can be made more reliable and stable, reducing the risk of the magnetic module 20 falling off the pad 10.

[0071] In some embodiments, referring to Figures 2-4, the magnetic module 20 is disposed on the outer periphery of the pad 10.

[0072] In the above technical solution, by setting the magnetic suction module 20 on the outer periphery of the pad 10, it is convenient to adjust the magnetic suction module; and it will not affect the flatness of the upper surface of the pad 10, so that the upper surface of the pad 10 can contact the bottom surface of the bearing seat 40, so that there is a large contact area between the pad 10 and the bearing seat 40, so that the support cylinder 30 can support the bearing seat 40 more stably and reliably through the support pad 100, thereby supporting the roll more stably and reliably.

[0073] In some embodiments, referring to Figures 2-4, the magnetic module body 21 extends circumferentially along the pad 10.

[0074] In the above technical solution, by extending the magnetic module body 21 along the circumference of the pad 10, the magnetic attraction area between the magnetic module 20 and the bearing seat 40 can be larger, so that the support pad 100 can be more stably attracted and fixed on the bearing seat 40 by the magnetic module 20.

[0075] In some embodiments, referring to Figures 3-4, the upper surface of the magnetic module 20 is flush with the upper surface of the pad 10; or, the upper surface of the magnetic module 20 is lower than the upper surface of the pad 10.

[0076] In the above technical solution, by ensuring that the upper surface of the magnetic module 20 is not higher than the upper surface of the pad 10, when the magnetic module 20 is adsorbed and fixed on the bottom surface of the bearing seat 40, the upper surface of the pad 10 can contact the bottom surface of the bearing seat 40, thereby creating a larger contact area between the support pad 100 and the bearing seat 40. This allows the support cylinder 30 to provide more stable and reliable support to the bearing seat 40 through the support pad 100, thus providing more stable and reliable support to the roll.

[0077] In some embodiments, referring to FIG2, there are multiple magnetic modules 20, and the multiple magnetic modules 20 are arranged at intervals along the circumference of the pad 10.

[0078] In the above technical solution, by setting multiple magnetic attraction modules 20 at intervals along the circumference of the pad 10, the magnetic attraction force between the support pad 100 and the bearing seat 40 can be increased, and the magnetic attraction force between the support pad 100 and the bearing seat 40 can be more evenly distributed. This makes the support cylinder 30 support the bearing seat 40 through the support pad 100 more stable and reliable, thereby making the support of the roll more stable and reliable.

[0079] In some embodiments, referring to FIG2, there are two magnetic modules 20, which are located on opposite sides of the pad 10.

[0080] In the above technical solution, by setting two magnetic attraction modules 20 and placing them on opposite sides of the pad 10, the number of magnetic attraction modules 20 can be moderate, and the magnetic attraction force between the support pad 100 and the bearing seat 40 can be large, and the magnetic attraction force between the support pad 100 and the bearing seat 40 can be distributed more evenly. As a result, the support cylinder 30 provides more stable and reliable support to the bearing seat 40 through the support pad 100, thereby providing more stable and reliable support to the roll.

[0081] In some embodiments, referring to Figures 4-6, the magnetic module body 21 includes a magnetic base 211 and a permanent magnet 214. The magnetic base 211 includes two sub-magnetic bases 212 and a partition plate 213. The sub-magnetic bases 212 are magnetically conductive, and the partition plate 213 is a non-magnetically conductive component. The two sub-magnetic bases 212 are arranged horizontally, and the partition plate 213 is sandwiched between the two sub-magnetic bases 212. The two sub-magnetic bases 212 and the partition plate 213 together define a receiving cavity 23, and the permanent magnet 214 is disposed within the receiving cavity 23. The adjusting member 22 is connected to the permanent magnet 214 to drive the permanent magnet 214 to move between a first position and a second position. When the permanent magnet 214 is in the first position, the N and S poles of the permanent magnet 214 are arranged along the first direction and are opposite to the partition plate 213, and the magnetic attraction module 20 is in the first state. When the permanent magnet 214 is in the second position, the N and S poles of the permanent magnet 214 are arranged along the second direction and are opposite to the sub-magnetic base 212, and the magnetic attraction module 20 is in the second state. The angle between the second direction and the vertical direction is greater than the angle between the first direction and the vertical direction.

[0082] The sub-magnetic base 212 can be made of one of the following materials: iron, cobalt, or nickel; the separator 213 can be made of copper; and the permanent magnet 214 can be a bar magnet.

[0083] For example, the first direction can refer to the e1 direction in Figures 5 and 6, and the second direction can refer to the e2 direction in Figures 5 and 6.

[0084] The magnetic material is also called soft magnetic material. The sub-magnetic base 212 is made of magnetic material. By taking advantage of the characteristics of magnetic material that it is easy to magnetize and easy to demagnetize, the magnetic strength of the magnetic module body 21 can be adjusted.

[0085] When the permanent magnet 214 is in the first position, the N and S poles of the permanent magnet 214 are arranged along the first direction and the N and S poles of the permanent magnet 214 are opposite to the partition plate 213. At this time, the sub-magnetic base 212 is magnetized, and the magnetic module body 21 as a whole displays strong magnetism. The magnetic module 20 is in the first state. When the permanent magnet 214 is in the second position, the N and S poles of the permanent magnet 214 are arranged along the second direction and the N and S poles of the permanent magnet 214 are opposite to the sub-magnetic base 212. At this time, since the central magnetic field of the permanent magnet 214 is weak, the magnetic force of the sub-magnetic base 212 is small or even close to zero. The magnetic module body 21 as a whole displays weak magnetism. The magnetic module 20 is in the second state.

[0086] In the above technical solution, the magnetic module 20 is configured to include a permanent magnet 214 and a magnetic base 211. The magnetic base 211 is configured to include two sub-magnetic bases 212 and a partition plate 213 sandwiched between the two sub-magnetic bases 212. The partition plate 213 is configured as a non-magnetic component and the two sub-magnetic bases 212 are configured as magnetic components. The partition plate 213 can isolate the two sub-magnetic bases 212 from magnetic interference. The permanent magnet 214 is placed in the receiving cavity 23 defined by the magnetic base 211. The permanent magnet 214 can be moved between a first position and a second position by connecting the adjusting component 22 to the permanent magnet 214. When the permanent magnet 214 is in different positions, the magnetic magnitude displayed by the magnetic module 20 is different, so the magnetic magnitude of the magnetic module 20 can be easily adjusted. This makes the structure of the magnetic module 20 simple and easy to adjust and control.

[0087] In some embodiments, the angle between the first direction and the vertical direction is 0 to 10°, and the angle between the second direction and the vertical direction is 80° to 90°.

[0088] In the above technical solution, when the magnetic module 20 is in the first state, the angle between the setting direction of the N and S poles of the permanent magnet 214 and the vertical direction is small or parallel to the vertical direction. This allows the N and S poles of the permanent magnet 214 to be directly opposite the partition plate 213 of the magnetic base 211, thereby making the overall magnetic field of the magnetic module 20 larger and the magnetic attraction between the magnetic module 20 and the bearing seat 40 larger. When the magnetic module 20 is in the second state, the angle between the setting direction of the N and S poles of the permanent magnet 214 and the vertical direction is larger. This allows the N and S poles of the permanent magnet 214 to be directly opposite the sub-magnetic base 212 of the magnetic base 211 and offset from the partition plate 213 by a large angle, thereby making the overall magnetic field of the magnetic module 20 smaller or non-magnetic, and the magnetic attraction between the magnetic module 20 and the bearing seat 40 smaller or non-magnetic, thus facilitating the separation of the support pad 100 and the bearing seat 40.

[0089] In some embodiments, the adjusting member 22 is rotatably disposed on the magnetic base 211 and connected to the middle part of the permanent magnet 214 to drive the permanent magnet 214 to rotate.

[0090] In the above technical solution, by rotatably setting the adjusting member 22 on the magnetic base 211 and connecting it to the middle of the permanent magnet 214, the permanent magnet 214 can be rotated around the middle by rotating the adjusting member 22, thereby conveniently realizing the movement of the permanent magnet 214 driven by the adjusting member 22 to switch the state of the magnetic module 20.

[0091] In some embodiments, referring to Figures 2-4, the magnetic module 20 is disposed on the outer periphery of the pad 10, and the adjusting member 22 is installed on one side of the magnetic base 211 along the circumferential direction of the pad 10.

[0092] In the above technical solution, by setting the magnetic suction module 20 on the outer periphery of the pad 10, it is convenient to adjust the magnetic suction module; and it does not affect the flatness of the upper surface of the pad 10, so that the upper surface of the pad 10 can contact the bottom surface of the bearing seat 40, so that there is a large contact area between the pad 10 and the bearing seat 40, so that the support cylinder 30 can support the bearing seat 40 more stably and reliably through the support pad 100, thereby supporting the roll more stably and reliably; and by installing the adjusting member 22 on one side of the magnetic base 211 along the circumferential direction of the pad 10, it is convenient to operate the adjusting member 22.

[0093] In some embodiments, the upper end face of the piston 32 contacts the lower surface of the support pad 100 to support the support pad 100 and the bearing seat 40. When the magnetic module 20 is in the second state, the support cylinder 30 is used to hold the support pad 100.

[0094] The following is a brief description of the roll replacement process, using the support cylinder 30 as an example of a hydraulic cylinder: When the roll is worn and needs to be replaced, the magnetic force of the magnetic module 20 is reduced by adjusting the adjusting component 22 so that the magnetic module 20 is in the second state. In this case, the magnetic attraction between the support pad 100 and the bearing seat 40 is small or non-existent. At this time, the hydraulic cylinder is depressurized, and the support pad 100 falls to the support cylinder 30 under its own weight and is supported by the support rod. At this time, the roll and the bearing seat 40 can be removed together for easy replacement. After the roll is replaced, when the roll and the bearing seat 40 are installed above the support cylinder 30, the magnetic force of the magnetic module 20 is increased by adjusting the adjusting component 22 so that the magnetic module 20 is in the first state. In this case, the magnetic attraction between the support pad 100 and the bearing seat 40 is large, and the support pad 100 can be automatically attracted and fixed to the bottom surface of the bearing seat 40 under the action of magnetic attraction. Then, the hydraulic cylinder is pressurized again.

[0095] In the above technical solution, the upper end face of the piston 32 contacts the lower surface of the support pad 100 to support the support pad 100 and the bearing seat 40. Since the support cylinder 30 and the support pad 100 are not connected but only have a contact support relationship, the combination of the support cylinder 30 and the support pad 100 is more flexible. Different specifications and sizes of support cylinder 30 or support pad 100 can be selected as needed. Furthermore, when the magnetic module 20 is in the second state, the support pad 100 is separated from the bearing seat 40 and supported by the support cylinder 30, which facilitates the placement of the support pad 100 after it is separated from the bearing seat 40. During the disassembly and assembly of the support pad 100, no additional manual labor or additional structure is required to support the support pad 100, making the disassembly and assembly process of the pad 10 simpler.

[0096] In some embodiments, referring to Figures 2-4, a positioning post 11 is provided on one of the upper surface of the pad 10 and the bottom surface of the bearing seat 40, and a positioning hole is provided on the other of the upper surface of the pad 10 and the bottom surface of the bearing seat 40. The positioning post 11 is inserted into the positioning hole in the vertical direction.

[0097] For example, the upper surface of the pad 10 may be provided with a positioning post 11, and the bottom surface of the bearing housing 40 may be provided with a positioning hole; or, the bottom surface of the bearing housing 40 may be provided with a positioning post 11, and the upper surface of the pad 10 may be provided with a positioning hole.

[0098] For example, there can be multiple positioning holes and multiple positioning posts 11. The number of multiple positioning holes and multiple positioning posts 11 are the same and correspond one-to-one.

[0099] In the above technical solution, by setting a positioning post 11 on one of the pad 10 and the bearing seat 40 and setting a positioning hole on the other, when the support pad 100 is adsorbed and fixed on the bearing seat 40, the installation position of the support pad 100 can be quickly positioned by inserting the positioning post 11 into the positioning hole, thus avoiding uneven force caused by arbitrary changes in the position of the support pad 100.

[0100] In some embodiments, referring to Figures 2-3, there are two magnetic modules 20, which are located on opposite sides of the pad 10 in the horizontal direction. The positioning post 11 is disposed on the upper surface of the pad 10 and is located between the two magnetic modules 20.

[0101] For example, there can be multiple positioning posts 11, all of which are located between the two magnetic modules 20 and arranged along the arrangement direction of the two magnetic modules 20.

[0102] By setting two magnetic modules 20 and placing them on opposite sides of the pad 10, the number of magnetic modules 20 can be moderate, and the magnetic attraction between the support pad 100 and the bearing seat 40 can be large and the magnetic attraction between the support pad 100 and the bearing seat 40 can be evenly distributed. This makes the support cylinder 30 support the bearing seat 40 more stably and reliably through the support pad 100, thus making the support of the roll more stable and reliable. Furthermore, by placing the positioning post 11 between the two magnetic modules 20, the support pad 100 can be more evenly and stably attracted and fixed at the set position on the bearing seat 40.

[0103] In a second aspect, this application provides a rolling mill, comprising: a support mechanism 200 according to the first aspect of this application and a rolling mill, the rolling mill being mounted on a bearing housing 40 via bearings.

[0104] In the above technical solution, by setting the support mechanism 200, the time for disassembling and assembling the support pad 100 during the roll replacement process can be reduced, which is conducive to improving production efficiency.

[0105] The support mechanism 200 and the rolling device according to some embodiments of this application are described below with reference to Figures 1-6.

[0106] In this embodiment, the rolling equipment includes a roll, a bearing, and a support mechanism 200.

A separable support pad 100 is provided on the bottom surface of the bearing housing 40.

[0107] The support pad 100 includes a pad 10 and a magnetic module 20. The pad 10 is square, and a positioning post 11 is provided on the upper surface of the pad 10. A positioning hole is provided on the bottom surface of the bearing seat 40. There are two magnetic modules 20, which are located on opposite sides of the pad 10 along the horizontal direction. The magnetic module 20 includes a magnetic base 211 and a permanent magnet 214. The magnetic base 211 includes two sub-magnetic bases 212 and a partition plate 213. The sub-magnetic bases 212 are magnetically conductive, and the partition plate 213 is a non-magnetically conductive component. The two sub-magnetic bases 212 are arranged horizontally, and the partition plate 213 is sandwiched between the two sub-magnetic bases 212. The two sub-magnetic bases 212 and the partition plate 213 together define a receiving cavity 23. The permanent magnet 214 is disposed in the receiving cavity 23. The adjusting component 22 and the permanent magnet The body 214 is connected to drive the permanent magnet 214 to move between a first position and a second position; when the permanent magnet 214 is in the first position, the N and S poles of the permanent magnet 214 are arranged along the first direction and opposite to the partition plate 213, and the magnetic attraction module 20 is in the first state; when the permanent magnet 214 is in the second position, the N and S poles of the permanent magnet 214 are arranged along the second direction and opposite to the sub-magnetic base 212, and the magnetic attraction module 20 is in the second state, the second direction is parallel to the horizontal direction, and the first direction is parallel to the vertical direction.
