Furthermore, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] This utility model discloses a calender roll cleaning device, referenced Figure 1 and Figure 2As shown, the calender roll cleaning device includes a frame 100, a drive assembly 200, and a cleaning assembly 300. The frame 100 is provided with two spaced-apart bearings 110 for supporting the calender roll 10. The drive assembly 200 is mounted on the frame 100 and is used to cooperate with the calender roll 10 to drive the calender roll 10 to rotate. The cleaning assembly 300 is mounted on the frame 100 and can extend into the calender roll 10. The cleaning assembly 300 includes a cleaning seat 310, a cleaning brush 320 connected to the cleaning seat 310, and a nozzle 330 connected to the cleaning seat 310. The cleaning seat 310 has a fluid channel, and the nozzle 330 communicates with the fluid channel. One end of the fluid channel is connected to an external liquid source. Understandably, in actual operation, after the calender roll 10 is installed on the two bearing seats 110, the drive assembly 200 is connected to one end of the calender roll 10, and the cleaning brush 320 is inserted into the calender roll 10, with the cleaning brush 320 abutting against the inner wall of the calender roll 10. Then, the drive assembly 200 is activated to drive the calender roll 10 to rotate. During the rotation of the calender roll 10, the cleaning brush 320 can clean the inner wall of the calender roll 10, effectively removing various stubborn dirt, oxides, and impurities, so that the inner wall of the calender roll 10 has a high degree of integrity and smoothness. After cleaning, the cleaning agent is introduced into the cleaning seat 310, so that the cleaning agent flows from the fluid channel to the nozzle 33. The rust inhibitor is evenly distributed on the inner wall of the calender roll 10 under the spraying action of the nozzle 330, and the inner wall of the calender roll 10 is rinsed. After rinsing, the rust inhibitor is introduced into the cleaning seat 310. The rust inhibitor flows to the nozzle 330 through the fluid channel and is evenly distributed on the inner wall of the calender roll 10 under the spraying action of the nozzle 330. The rust inhibitor reacts chemically with the surface of the inner wall of the calender roll 10 to form a dense and uniform passivation film, which effectively isolates moisture, oxygen and other corrosive media from contact with the inner wall of the calender roll 10, significantly extends the scaling cycle of the calender roll 10, improves its corrosion resistance and long-term operating stability, and thus extends the service life of the calender roll 10.

[0031] In summary, the calender roll cleaning device of this embodiment automatically cleans the inner wall of the calender roll 10 using the cleaning brush 320, improving cleaning efficiency and effect. The nozzle 330 sprays cleaning agent and rust inhibitor sequentially toward the inner wall of the calender roll 10. The cleaning agent can effectively rinse the inner wall of the calender roll 10, and the rust inhibitor can effectively isolate moisture, oxygen and other corrosive media from contact with the inner wall of the calender roll 10, significantly extending the scaling cycle of the calender roll 10, improving its corrosion resistance and long-term operational stability, thereby extending the service life of the calender roll 10.

[0032] refer to Figure 3As shown, the bearing 110 includes a fixed seat 111 and a movable seat 112. The fixed seat 111 is fixed to the frame 100, and the movable seat 112 is detachably installed on the fixed seat 111. Both the fixed seat 111 and the movable seat 112 are provided with half-holes, and the two half-holes are joined together to form a shaft hole for accommodating the calender roll 10. It can be understood that in the actual installation process, it is only necessary to place both ends of the calender roll 10 into the half-holes of the fixed seat 111, and then install the movable seat 112 onto the fixed seat 111 to complete the support of the calender roll 10. This connection method is very convenient and facilitates the installation and removal of the calender roll 10.

[0033] Optionally, the fixed base 111 has a first mounting hole, and the movable base 112 has a second mounting hole. The mounting component passes through the second mounting hole and connects to the first mounting hole to fix the movable base 112 to the fixed base 111. In actual installation, when installing the movable base 112 onto the fixed base 111, the first and second mounting holes need to be aligned. Then, the mounting component passes through the second mounting hole and connects to the first mounting hole to complete the fixation of the movable base 112. This simplifies the fixing operation of the movable base 112 and improves the connection stability between the movable base 112 and the fixed base 111. In embodiments of this invention, the mounting component can be selected from screws, pins, or other structures according to actual needs. Of course, in other embodiments of this invention, the movable base 112 and the fixed base 111 can also be connected by a snap-fit ​​connection or other methods.

[0034] It should be noted that in other embodiments of this utility model, the bearing seat 110 may also have other structures. For example, both bearing seats 110 may have shaft holes. One bearing seat 110 may be fixed relative to the frame 100, while the other may be slidably mounted on the frame 100. When actually installing the calender roll 10, one end of the calender roll 10 is first inserted into the fixed bearing seat 110, and then the movable bearing seat 110 is adjusted to engage with the other end of the calender roll 10.

[0035] refer to Figure 3As shown, the drive assembly 200 includes a drive source 210, a conveyor belt assembly 220, and a drive base 230. The drive source 210 is mounted on the frame 100. The conveyor belt assembly 220 includes a drive wheel 221, a conveyor belt 223, and a driven wheel 222. The drive wheel 221 is connected to the output shaft of the drive source 210, and the drive base 230 is connected to the driven wheel 222. The drive base 230 is used to connect to one end of the calender roll 10. It can be understood that in the actual installation process, after the calender roll 10 is installed on the frame 100, the drive base 230 is connected to one end of the calender roll 10, and then the conveyor belt 223 is installed on the drive wheel 221 and the driven wheel 222. After starting the drive source 210, the calender roll 10 can be driven to rotate. Using the conveyor belt assembly 220 to drive the calender roll 10 facilitates installation and disassembly, and also facilitates control of the calender roll 10's rotation speed, which helps ensure a cleaning effect.

[0036] Optionally, the drive base 230 includes a connected connecting cylinder 231 and a connecting flange 232. The connecting cylinder 231 is connected to the driven wheel 222, and the connecting flange 232 is connected to one end of the calender roll 10 via a connecting piece 400. The connecting cylinder 231 and the connecting flange 232 can be connected by welding, snap-fitting, or other methods. The connecting cylinder 231 and the driven wheel 222 can also be connected by welding, snap-fitting, or other methods. The connection methods of the connecting cylinder 231, the connecting flange 232, and the driven wheel 222 are not limited here. The connection between the drive base 230 and the calender roll 10 is achieved through the connection method of the connecting flange 232 and the connecting piece 400, ensuring a stable connection between the entire drive assembly 200 and the calender roll 10. This ensures that the calender roll 10 can move stably under the drive of the drive assembly 200 during the cleaning process.

[0037] Alternatively, multiple connectors 400 may be arranged circumferentially around the connecting flange 232. This improves the connection stability between the drive seat 230 and the calender roll 10, ensuring that the calender roll 10 moves stably under the drive of the drive assembly 200 during the cleaning process. It should be noted that in this embodiment, the connector 400 is a bolt; however, fixing pins can also be selected according to actual needs.

[0038] refer to Figure 4As shown, the cleaning assembly 300 also includes a connecting seat 340 and a connecting unit 350. The connecting seat 340 is connected to both ends of the cleaning seat 310. One end of the connecting unit 350 is connected to the connecting seat 340, and the other end is adjustablely connected to the frame 100 in the vertical direction. It is understood that in actual operation, after the calender roll 10 is installed on the bearing seat 110, the cleaning seat 310 is inserted into the calender roll 10 and connected to the connecting seat 340 via the connecting unit 350. The position of the connecting unit 350 is adjusted to ensure that the cleaning brush 320 on the cleaning seat 310 can abut against the inner wall of the calender roll 10. This ensures that the calender roll 10 can be stably cleaned by the cleaning brush 320 during rotation.

[0039] Optionally, the frame 100 is provided with a connecting ear 120, which has a connecting hole. The connecting unit 350 includes an adjusting stud 351 and an adjusting nut 352. One end of the adjusting stud 351 is connected to the connecting seat 340, and the other end extends out of the connecting ear 120. There are two adjusting nuts 352, which abut against the two opposite sides of the connecting ear 120. Understandably, in practice, the adjusting stud 351 is first inserted into the connecting lug 120, and the adjusting nut 352 is installed on the adjusting stud 351. After the calender roll 10 is installed on the bearing seat 110, the adjusting stud 351 is rotated to connect it with the connecting seat 340. Then, the adjusting nut 352 is rotated. After the adjusting nut 352 abuts against the connecting lug 120, the adjusting nut 352 is rotated to drive the adjusting stud 351 to move in the up and down direction relative to the connecting lug 120. This ensures that the cleaning brush 320 on the cleaning seat 310 can abut against the inner wall of the calender roll 10, thereby ensuring that the calender roll 10 can be stably cleaned by the cleaning brush 320 during rotation.

[0040] refer to Figure 1 As shown, the calender roll cleaning device also includes a recovery tank 500, which is installed on the frame 100 and located below the shaft seat 110. It is understood that the recovery tank 500 can recover cleaning agents and rust removers, facilitating the recycling and reuse of the liquids and reducing pollution to the working environment.

[0041] Optionally, the calender roll cleaning device also includes a collection box 600, which is located below the recovery tank 500. The two ends of the recovery tank 500 are higher than the middle, and a drain pipe is installed in the middle of the recovery tank 500, corresponding to the collection box 600. During actual operation, the liquid in the recovery tank 500 can flow from both ends towards the middle, and then be discharged into the collection box 600 through the drain pipe. This facilitates the recycling and reuse of the liquid and reduces pollution to the working environment.

[0042] Optionally, the calender roll cleaning device also includes an intelligent control system. This system controls the rotational speed of the calender roll 10 driven by the drive assembly 200, as well as the spraying speed of the cleaning agent and rust remover, thereby achieving efficient cleaning operations in all directions without blind spots. In this embodiment, the intelligent control system can be configured using a microcontroller or control chip in conjunction with a touchscreen or button control panel, based on existing technology. Therefore, there is no need to describe or limit the model and control method of the intelligent control system.

[0043] The advantages of this calender roll cleaning device are as follows:

[0044] First, the calender roll cleaning device is equipped with an intelligent control system to ensure the accuracy and convenience of operation, while also possessing high flexibility and adaptability. It can penetrate deep into the complex areas inside the calender roll 10 to achieve efficient cleaning operations in all directions without blind spots.

[0045] Secondly, to address the cleaning requirements of the inner wall of the calender roll 10, a high-quality steel wire brush with specific hardness and toughness was selected as the cleaning brush 320. Through precise mechanical calculations and simulations, the optimal rotation speed and contact pressure of the steel wire brush during the cleaning process were determined. During the cleaning process, the steel wire brush performs fine grinding on the inner wall of the calender roll 10 using set parameters, effectively removing various stubborn dirt, oxides, and impurities. At the same time, the grinding force and path are strictly controlled to avoid causing any microscopic damage to the roll wall, ensuring the integrity and smoothness of the roll wall surface.

[0046] Third, after the wire brush grinding is completed and the inner wall of the calender roll 10 is confirmed to be clean to meet the standards through strict testing, the rust remover is sprayed onto the inner wall of the calender roll 10. The rust remover reacts chemically with the inner wall of the calender roll 10 to form a dense and uniform passivation film, which effectively isolates moisture, oxygen and other corrosive media from contact with the roll wall, thereby significantly extending the scaling cycle of the calender roll 10 and improving its corrosion resistance and long-term operational stability.
