However, the support mechanisms on both sides of the pressing rollers can hinder the replacement of the steel strip. Furthermore, after disassembling the pressing rollers and support mechanisms, the pressing rollers cannot be effectively supported. Often, the steel strip is replaced by disassembling the roller pressing equipment and using a crane to lift the pressing rollers. However, this design requires disassembling the entire roller pressing equipment, making replacement difficult and inefficient. Summary of the Invention

[0042] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or lateral positional relationship based on the orientation or lateral positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] Example 1

[0046] Please refer to the following: Figures 1 to 6This invention provides a rolling pressing system, which includes a rolling pressing device 1 and a replacement auxiliary device. The rolling pressing device 1 includes a pressing roller assembly and two support mechanisms 13 detachably supported on both sides of the pressing roller assembly. The replacement auxiliary device is used to detachably replace one of the support mechanisms 13 to support the pressing roller assembly and to support the steel strip to be installed on the pressing roller assembly. The steel strip to be installed on the pressing roller assembly can be moved onto the pressing roller assembly. When it is necessary to install the steel strip 3 to be installed onto the pressing roller assembly, firstly, the steel strip 3 to be installed is installed on the replacement auxiliary device. Then, the replacement auxiliary device is moved to one side of the pressing roller assembly to replace the supporting function of the support mechanism 13 on that side. Next, the support mechanism 13 on that side is disassembled. Then, the steel strip 3 to be installed is moved along that side to the pressing roller assembly. Next, the support mechanism 13 is reinstalled back on one side of the pressing roller assembly. Finally, the replacement auxiliary device is detached from the pressing roller assembly, thereby realizing the replacement of the steel strip 3 to be installed onto the pressing roller assembly.

[0047] In addition, as an optional implementation, the replacement auxiliary device is also used to support the steel strip to be disassembled on the pressure roller assembly. The steel strip to be disassembled on the pressure roller assembly can be moved to the replacement auxiliary device. When it is necessary to disassemble the steel strip to be disassembled on the pressure roller assembly, firstly, the replacement auxiliary device is moved to support one side of the pressure roller assembly to replace the supporting function of the support mechanism 13 on that side. Then, the support mechanism 13 on that side is disassembled. Next, the steel strip to be disassembled is moved to the replacement auxiliary device. Then, the support mechanism 13 is installed back on one side of the pressure roller assembly. Then, the replacement auxiliary device is removed from the pressure roller assembly. Finally, the steel strip to be disassembled is removed from the replacement auxiliary device, thereby assisting in the disassembly of the steel strip to be disassembled. As another optional implementation, the steel strip can be directly disassembled by cutting or other methods. For example, when the rolling mill 1 needs to replace the steel strip with a different model, the steel strip to be disassembled can be disassembled by replacing the auxiliary device to ensure the integrity of the steel strip after disassembly; as another example, when the steel strip to be disassembled is a steel strip that is to be scrapped, the steel strip can be disassembled directly by cutting or other means, without any restrictions on this.

[0048] The rolling system using this solution only requires disassembling one side of the support mechanism 13 to replace the steel belt, thereby reducing the difficulty of steel belt replacement and improving the efficiency of steel belt replacement.

[0049] The replacement auxiliary device can be moved to the left side of its supporting pressing roller group to replace the left supporting mechanism 13 or to the right side of its supporting pressing roller group to replace the right supporting mechanism 13. This embodiment does not limit it. This embodiment takes the example of the replacement auxiliary device being moved to the left side of its supporting pressing roller group to replace the left supporting mechanism 13.

[0050] In some embodiments, the pressing roller assembly includes a lower pressing roller assembly 11 and an upper pressing roller assembly 12. The lower pressing roller assembly 11 is used to wind a lower steel strip, and the upper pressing roller assembly 12 is used to wind an upper steel strip. Specifically, the lower pressing roller assembly 11 includes a lower driving roller 111 and a lower driven roller 112, with the lower steel strip wound on the lower driving roller 111 and the lower driven roller 112. The upper pressing roller assembly 12 includes an upper driving roller 121 and an upper driven roller 122, with the upper steel strip wound on the upper driving roller 121 and the upper driven roller 122.

[0051] In some embodiments, the rolling mill 1 further includes a lower adjustment mechanism 14 for adjusting the distance between the lower drive roller 111 and the lower driven roller 112. This configuration allows the distance between the lower drive roller 111 and the lower driven roller 112 to be reduced when the steel strip needs to be replaced, facilitating the movement of the steel strip to be removed from the lower pressure roller assembly 11 to the replacement auxiliary device or the movement of the steel strip 3 to be installed onto the lower pressure roller assembly 11. Then, the lower adjustment mechanism 14 adjusts the lower drive roller 111 and the lower driven roller 112 back to their previous distance, ensuring that the steel strip installed on the lower pressure roller assembly 11 reaches a preset tension.

[0052] It is understood that in other preferred embodiments, the distance between the lower driving roller 111 and the lower driven roller 112 can also be adjusted by pushing the lower driving roller 111 or the lower driven roller 112 with an external force, and this is not limited here.

[0053] Furthermore, the lower adjustment mechanism 14 is a tensioning cylinder mounted on the lower driving roller 111 and / or the lower driven roller 112. Using a tensioning cylinder for adjustment is simple and convenient.

[0054] Specifically, the lower adjustment mechanism 14 is a tensioning cylinder provided on the lower driving roller 111 and / or the lower driven roller 112. The lower adjustment mechanism 14 is a tensioning cylinder provided on the lower driving roller 111, a tensioning cylinder provided on the lower driven roller 112, or a tensioning cylinder provided on both the lower driving roller 111 and the lower driven roller 112. Considering that the mobility of the lower driven roller is stronger than that of the lower driving roller, this embodiment preferably adopts the design of the lower adjustment mechanism 14 being a tensioning cylinder provided on the lower driven roller 112.

[0055] In some embodiments, the rolling mill 1 further includes an upper adjustment mechanism 15 for adjusting the distance between the upper driving roller 121 and the upper driven roller 122. This configuration allows the distance between the upper driving roller 121 and the upper driven roller 122 to be reduced when the steel strip needs to be replaced, facilitating the movement of the steel strip to be removed from the upper pressure roller assembly 12 to the replacement auxiliary device or the replacement of the steel strip 3 to be installed onto the upper pressure roller assembly 12. Then, the upper adjustment mechanism 15 is used to adjust the upper driving roller 121 and the upper driven roller 122 back to their previous distance, so that the steel strip installed on the upper pressure roller assembly 12 reaches a preset tension.

[0056] It is understood that in other preferred embodiments, the distance between the upper driving roller 121 and the upper driven roller 122 can also be adjusted by pushing the upper driving roller 121 or the upper driven roller 122 with external force, and this is not limited here.

[0057] Furthermore, the upper adjustment mechanism 15 is a tensioning cylinder mounted on the upper driving roller 121 and / or the upper driven roller 122. Using a tensioning cylinder for adjustment is simple and convenient.

[0058] Specifically, the upper adjustment mechanism 15 is a tensioning cylinder provided on the upper driving roller 121 and / or the upper driven roller 122. The upper adjustment mechanism 15 includes a tensioning cylinder provided on the upper driving roller 121, a tensioning cylinder provided on the upper driven roller 122, and a tensioning cylinder provided on both the upper driving roller 121 and the upper driven roller 122. Considering that the mobility of the upper driven roller is stronger than that of the upper driving roller, this embodiment preferably adopts the design of the upper adjustment mechanism 15 being a tensioning cylinder provided on the upper driven roller 122.

[0059] In some embodiments, the support mechanism 13 includes a lower support assembly 131 for supporting the lower pressure roller group 11 and an upper support assembly 132 for supporting the upper pressure roller group 12. The replacement auxiliary device includes a lower replacement auxiliary device 21 for supporting the lower pressure roller group 11 and for supporting the steel strip to be installed on the lower pressure roller group 11, and an upper replacement auxiliary device 22 for supporting the upper pressure roller group 12 and for supporting the steel strip to be installed on the upper pressure roller group 12.

[0060] In some embodiments, the lower support assembly 131 is a lower support foot provided on the lower pressure roller group 11, and the upper support assembly 132 is a pad provided between the lower pressure roller group 11 and the upper pressure roller group 12. With this configuration, when only the steel strip on the lower pressure roller group 11 needs to be replaced, or when both the steel strip on the lower pressure roller group 11 and the steel strip on the upper pressure roller group 12 need to be replaced, the lower replacement auxiliary device 21 carrying the steel strip 3 to be installed supports the lower pressure roller group 11, and the upper replacement auxiliary device 22 supports the upper pressure roller group 12; or the lower replacement auxiliary device 21 carrying the steel strip 3 to be installed supports the lower pressure roller group 11, and the upper replacement auxiliary device 22 carrying the steel strip 3 to be installed supports the upper pressure roller group 12. Then, the lower support assembly 131 and the upper support assembly 132 can be disassembled to replace the lower steel strip or the lower and upper steel strips. When only the steel strip on the upper pressure roller group 12 needs to be replaced, the upper replacement auxiliary device 22 carrying the steel strip 3 to be installed supports the upper pressure roller group 12, and the upper support assembly 132 can be disassembled to replace the upper steel strip.

[0061] It is understood that in other preferred embodiments, the upper support component 132 may also be designed as an independently set upper support foot, and this is not limited here.

[0062] Specifically, since the lower pressing roller group 11 includes a lower driving roller 111 and a lower driven roller 112, there are multiple lower support feet, and the multiple lower support frames are used to support the lower driving roller 111 and the lower driven roller 112 respectively.

[0063] In some embodiments, the lower replacement auxiliary device 21 includes a lower load-bearing support frame 211 for supporting the lower pressure roller group 11 and a lower steel strip support frame 212 disposed on the load-bearing support frame for supporting the steel strip to be installed onto the lower pressure roller group 11, thereby enabling the lower replacement auxiliary device 21 to support the pressure roller group and support the steel strip to be installed onto the pressure roller group.

[0064] Furthermore, the lower load-bearing support frame 211 includes a lower vertical support frame 2111 and a lower horizontal support frame 2112. The lower horizontal support frame 2112 is mounted on the lower vertical support frame 2111 and is used to support the lower pressing roller group 11. The lower steel strip support frame 212 is mounted on the lower horizontal support frame 2111. Specifically, the lower horizontal support frame 2112 is located at one end of the lower vertical support frame 2111, and the other end of the lower vertical support frame 2111 is connected to the lower pressing roller group 11 to support the lower pressing roller group 11.

[0065] Optionally, considering that the steel strip on the lower pressure roller group 11 is often relatively long, in order to better support the steel strip being replaced onto the lower pressure roller group 11, the lower replacement auxiliary device 21 further includes a lower auxiliary support frame 213 for assisting in supporting the steel strip to be installed onto the pressure roller group. It is understood that in other preferred embodiments, the lower auxiliary support frame 213 may not be provided, and this is not limited here.

[0066] In some embodiments, the upper replacement auxiliary device 22 includes an upper load-bearing support frame 221 for supporting the upper pressure roller group 12 and an upper steel strip support frame 222 disposed on the load-bearing support frame for supporting the steel strip to be installed onto the upper pressure roller group 12, thereby enabling the upper replacement auxiliary device 22 to support the pressure roller group and support the steel strip to be installed onto the pressure roller group.

[0067] Furthermore, the upper load-bearing support frame 221 includes an upper vertical support frame 2211 and an upper horizontal support frame 2212. The upper horizontal support frame 2212 is mounted on the upper vertical support frame 2211 and is used to support the upper pressing roller group 12. The upper steel strip support frame 222 is mounted on the upper horizontal support frame 2212. Specifically, the upper horizontal support frame 2212 is located at one end of the upper vertical support frame 2211, and the other end of the upper vertical support frame 2211 is connected to the upper pressing roller group 12 to support the upper pressing roller group 12.

[0068] Optionally, the upper replacement auxiliary device 22 may also include an upper auxiliary support frame for auxiliary support of the steel strip to be installed onto the upper pressure roller group 12. This is not limited here. In this embodiment, the design of the upper auxiliary device excluding the upper auxiliary support frame is used as an example.

[0069] In some embodiments, the lower replacement auxiliary device 21 further includes a lower movable auxiliary structure 214 for assisting the steel strip to move to the pressure roller group, so as to facilitate the replacement of the steel strip 3 to be installed on the lower steel strip support frame 212 onto the lower pressure roller group 11.

[0070] Furthermore, the lower movable auxiliary structure 214 is a rolling component located on the lower steel belt support frame 212. The steel belt 3 to be installed covers the rolling component, and the rolling of the rolling component helps the steel belt 3 to be installed to move quickly, thereby improving the steel belt replacement efficiency.

[0071] The rolling component can be a ball, roller, or pulley, etc., and is not limited thereto. In this embodiment, a pulley is used as an example of the rolling component.

[0072] In some embodiments, the upper replacement auxiliary device 22 further includes an upper movable auxiliary structure 223 for assisting the steel strip to move to the pressure roller group, so as to replace the steel strip 3 to be installed on the upper steel strip support frame 222 onto the upper pressure roller group 12.

[0073] Furthermore, the upper auxiliary structure 223 is a rolling component mounted on the upper steel strip support frame 222. The steel strip 3 to be installed covers the rolling component, and the rolling of the rolling component helps the steel strip 3 to be installed to move quickly, thereby improving the replacement efficiency of the steel strip.

[0074] The rolling component can be a ball, roller, or pulley, etc., and is not limited thereto. In this embodiment, a pulley is used as an example of the rolling component.

[0075] The roller pressing system of this invention includes a roller pressing device 1 and a replacement auxiliary device. The roller pressing device 1 comprises a pressing roller assembly and two detachable support mechanisms 13 on both sides of the pressing roller assembly. The replacement auxiliary device is used to detachably replace one of the support mechanisms 13 to support the pressing roller assembly and to support the steel strip to be installed on the pressing roller assembly. The steel strip to be installed on the pressing roller assembly can be moved onto the pressing roller assembly. Using this roller pressing system, the steel strip can be replaced simply by disassembling one of the support mechanisms 13, thereby reducing the difficulty and increasing the efficiency of steel strip replacement.

[0076] Example 2

[0077] Please refer to the following: Figure 7 and Figure 8 Embodiment 2 of the present invention provides a method for replacing the steel strip in a roll forming system. The specific structure of the steel roll forming system can be found in Embodiment 1, and will not be repeated in this embodiment. The method for replacing the steel strip includes:

[0078] 201: Remove the steel strip to be removed from the pressure roller assembly.

[0079] In some embodiments, removing the steel strip to be removed from the pressure roller assembly includes the following steps:

[0080] 201a: Connect the replacement auxiliary device to the pressure roller assembly to replace the supporting function of the support mechanism located on one side of the pressure roller assembly;

[0081] 201b: Disassemble the support mechanism located on one side of the pressing roller assembly;

[0082] 201c: Move the steel strip to be disassembled to the replacement auxiliary device;

[0083] 201d: Reinstall the support mechanism back onto one side of the pressing roller assembly;

[0084] 201e: Remove the replacement auxiliary device from the pressure roller assembly;

[0085] 201f: Remove the steel strip to be disassembled from the replacement auxiliary device.

[0086] By replacing the auxiliary device to assist in the disassembly of the steel strip, the integrity of the steel strip after disassembly can be ensured.

[0087] It is understood that in other preferred embodiments, the steel strip can also be disassembled directly by cutting or other methods, and this is not limited here.

[0088] 202: Fit the steel belt to be installed onto the replacement auxiliary device.

[0089] In some embodiments, the replacement auxiliary device includes a load-bearing support frame for supporting the pressure roller assembly and a steel strip support frame disposed on the load-bearing support frame for supporting the steel strip to be installed onto the pressure roller assembly, wherein the steel strip to be installed is fitted onto the steel strip support frame of the replacement auxiliary device.

[0090] 203: Connect the replacement auxiliary device to the pressure roller assembly to replace the supporting function of the support mechanism located on one side of the pressure roller assembly.

[0091] 204: Disassemble the support mechanism located on one side of the pressing roller assembly.

[0092] In some embodiments, the support mechanism includes a lower support assembly for supporting the lower pressure roller assembly and an upper support assembly for supporting the upper pressure roller assembly.

[0093] 205: Move the steel strip to be installed onto the pressing roller assembly.

[0094] 206: Reinstall the support mechanism back onto one side of the pressing roller assembly;

[0095] 207: Remove the replacement auxiliary device from the pressing roller assembly.

[0096] In some embodiments, before the step of moving the steel strip to be installed onto the pressure roller assembly, the steel strip replacement method further includes adjusting the distance between the driving roller and the driven roller on the pressure roller assembly via an adjusting mechanism. When the steel strip to be removed from the pressure roller assembly is assisted by a replacement auxiliary device, the step of adjusting the distance between the driving roller and the driven roller on the pressure roller assembly via the adjusting mechanism precedes step 201f; when the steel strip to be installed is assisted by a replacement auxiliary device onto the pressure roller assembly, the step of adjusting the distance between the driving roller and the driven roller on the pressure roller assembly via the adjusting mechanism can be set between steps 201 and 202, or between steps 202 and 203, between steps 203 and 204, or between steps 204 and 205.

[0097] This embodiment illustrates the installation of the steel strip to be installed onto the pressure roller assembly by simply replacing the auxiliary device. The step of adjusting the distance between the driving roller and the driven roller on the pressure roller assembly by adjusting the mechanism can be set between steps 201 and 202. In other preferred embodiments, other methods described above can also be used, which are not limited here.

[0098] The following is a brief explanation of the process of replacing the steel strip on the lower pressure roller group and the upper pressure roller group respectively.

[0102] 3) The steel strip to be installed is fitted onto the lower steel strip support frame;

[0103] 4) Connect the lower support frame to the lower pressure roller assembly and connect the upper support frame to one side of one side of the upper pressure roller assembly;

[0104] 5) Disassemble the lower support assembly and upper support assembly located on one side of the pressing roller assembly;

[0105] 6) The steel strip to be installed on the lower steel strip support frame moves to the right along the pulley until it is fitted onto the upper pressure roller assembly;

[0106] 7) Reinstall the lower support assembly and the upper support assembly back onto one side of the pressure roller assembly;

[0107] 8) Remove the lower and upper support frames from the pressing roller assembly.

[0108] 2. Replace the steel strip on the upper pressure roller assembly:

[0109] 1) Remove the steel strip to be removed from the upper pressure roller assembly;
