[0002] Rolls are key production equipment in industries such as metallurgy, papermaking, and textiles, and their performance directly affects production efficiency and product quality. However, during long-term use, the roll surface is prone to wear, oxidation, and surface defects due to high temperature, high pressure, and friction, which shortens the service life of the roll and even affects the normal operation of the production line. In order to prolong the service life of the roll and ensure its working performance, roll surface repair has become an essential maintenance process.

[0043] Please refer to the accompanying drawings Figure 5 The conveying mechanism 3 is arranged in the box mechanism 2 and functions to drive the roll to move in the device and then continuously heat treat multiple rolls. The conveying mechanism 3 comprises conveying shafts 301 and conveying pulleys 302. The left and right ends of the conveying shafts 301 are rotationally connected to the box side plates 202. The middle parts of the conveying pulleys 302 are fixedly connected to the outer surfaces of the conveying shafts 301. Steel conveying mesh belts 303 are arranged on the outer edges of the conveying pulleys 302. Multiple groups of roll brackets 304 are fixedly connected to the outer surfaces of the steel conveying mesh belts 303.

[0044] Specifically, the transmission shaft 301 is fixedly connected to the side plate 202 of the box body, and the transmission roller 302 is installed at the middle part of the transmission shaft 301 and rotates coaxially with the transmission shaft 301. The outer edge of the transmission roller 302 is provided with a steel transmission mesh belt 303, which has high high-temperature resistance and wear resistance and is suitable for long-time operation in a high-temperature environment. The steel transmission mesh belt 303 fixes and supports the roller to be heat treated through a plurality of roller bracket groups 304 on the surface thereof. With the rotation of the transmission shaft 301 and the transmission roller 302, the steel transmission mesh belt 303 drives the roller bracket 304 and the roller 304 carried thereby to move circularly inside the box body mechanism 2. Under the pushing of the driving mechanism 4, the rollers on the roller bracket 304 pass through the heat treatment area set by the heating mechanism 5 in sequence, so that the surface of each roller is uniformly heated and the required temperature and time for repair are reached.

[0045] Please refer to the accompanying drawings Figure 5 The driving mechanism 4 is arranged on the left side of the transmission mechanism 3 of the support base 1 and is used to provide power for the transmission mechanism 3. The driving mechanism 4 comprises transmission gears 401, a transmission chain 402 and a driving speed reducer 403. The middle parts of the transmission gears 401 are fixedly connected to the left ends of the transmission shafts 301. The transmission chain 402 is engagedly connected to the outer edges of the transmission gears 401. The transmission gears 401 are connected to each other through the transmission chain 402. The driving speed reducer 403 is fixedly connected to the left side of the box body mechanism 2. The driving speed reducer 403 is provided with a first driving motor 404 on the lower side. The right side of the first driving motor 404 is fixedly connected to the left side of the support base 1. The power output end of the first driving motor 404 is fixedly connected to the power input end of the driving speed reducer 403. The power output end of the driving speed reducer 403 is fixedly connected to the left ends of the front and rear transmission shafts 301.

[0046] Specifically, the first driving motor 404 is installed on the lower side of the driving speed reducer 403 and is fixedly connected to the left side of the support base 1. When the equipment is started, the first driving motor 404 receives a starting signal from the automatic control device 1002 in the device control mechanism 10 and starts to operate. The first driving motor 404 transmits power to the driving speed reducer 403. The built-in speed reducer gear group of the driving speed reducer 403 converts the high-speed rotation of the motor into low-speed high-torque output suitable for the operation of the transmission mechanism 3. The power output end of the driving speed reducer 403 is fixedly connected to the left ends of the transmission shafts 301, and the transmission shafts 301 on the front and rear sides are driven to rotate by the reduced rotary power.

[0047] A plurality of transmission gears 401 are fixedly connected to the left end of a plurality of transmission shafts 301, and transmission chains 402 are respectively engaged with the outer edges of the transmission gears 401. The transmission gears 401 are connected to each other through the transmission chains 402, and the continuous circulation of the transmission chains 402 realizes the synchronous movement of the plurality of transmission gears 401. The rotation of the transmission shafts 301 drives the transmission carrier wheels 302 to rotate coaxially through fixed connection. The outer edges of the transmission carrier wheels 302 are equipped with steel transmission mesh belts 303. With the rotation of the transmission carrier wheels 302, the steel transmission mesh belts 303 continuously move, thereby driving the roller carriers 304 and the rollers 304 carried thereby to move circularly inside the box mechanism 2. The first driving motor 404 realizes accurate control of the rotation speed of the transmission shafts 301 by adjusting its own rotation speed. In this way, the transmission speed can be adjusted according to the needs of the heat treatment process, and the rollers 304 can be ensured to stay in the heating area for a sufficient time to achieve the desired heat treatment effect.

[0048] Please refer to the accompanying drawings Figure 6 The heating mechanism 5 is fixedly connected inside the box mechanism 2, which functions to heat the inside of the box mechanism 2 and make the inside temperature reach the temperature required for roller heat treatment. The heating mechanism 5 includes heating fixed plates 501 and heating boxes 502. The opposite sides of the heating fixed plates 501 are fixedly connected to the adjacent sides of the box side plates 202, and the left and right sides of the heating boxes 502 are fixedly connected to the adjacent sides of the heating fixed plates 501. The middle parts of the heating boxes 502 are provided with heating installation grooves 503, and the inside of the heating installation grooves 503 is fixedly connected with heating devices 504.

[0049] Specifically, the heating fixed plates 501 are fixedly connected to the adjacent sides of the box side plates 202, forming the basic installation structure of the heating boxes 502 and providing installation positions for the heating boxes 502. A plurality of heating boxes 502 are evenly distributed inside the heating boxes 502 in two groups, and their relative positions are just aligned with the upper side of the steel transmission mesh belt 303. This design can ensure that the heat is evenly distributed inside the box, thereby realizing uniform heating of the rollers.

[0050] The middle part of the heating box 502 is provided with a plurality of heating installation grooves 503, which provide preset positions for the fixation of the heating devices 504. The heating installation grooves 503 are fixedly connected with the heating devices 504 inside. The heating devices 504 generate heat in the form of resistance heating, which can quickly and uniformly raise the temperature inside the box mechanism 2 to the required temperature level for roller heat treatment. The device control mechanism 10 can automatically turn on or off the corresponding heating devices 504 according to the preset temperature curve, and adjust their power output to adapt to different heat treatment process requirements. The plurality of heating devices 504 inside the heating box 502 are evenly distributed, ensuring that the temperature distribution in each area inside the box mechanism 2 is balanced, avoiding hot spots or cold spots. This ensures that the roller 304 is uniformly heated throughout the heat treatment process, improving the repair quality.

[0051] Please refer to the attached Figure 7 The protective gas delivery mechanism 6 is fixedly connected to the left and right sides of the box mechanism 2. Its function is to input protective gas into the interior of the box mechanism 2 through uniformly distributed pipelines. The protective gas delivery mechanism 6 includes side gas input branch pipes 601 and gas input main pipes 602. The side gas input branch pipes 601 are fixedly connected to the far sides of the box side plates 202 and penetrate through the box side plates 202. The gas input main pipes 602 are fixedly connected to the left and right far ends of the side gas input branch pipes 601. The middle parts of the gas input main pipes 602 are fixedly connected with side delivery pipelines 603 on the far sides. The input ends of the side delivery pipelines 603 are fixedly connected with the output ends of the protective gas input mechanism 7.

[0052] Specifically, the side gas input branch pipes 601 are fixedly connected to the far sides of the box side plates 202 and penetrate through the entire box side plates 202. These branch pipes are responsible for receiving protective gas from the gas input main pipes 602 and guiding it into the box mechanism 2, so that it is uniformly distributed inside the box mechanism 2. The gas input main pipes 602 are fixedly connected to the left and right far ends of the side gas input branch pipes 601, serving as the main delivery channel for protective gas. The side delivery pipelines 603 are used to connect the protective gas input mechanism 7 with the gas input main pipes 602, allowing protective gas to smoothly enter the gas input main pipes 602 from the protective gas input mechanism 7.

[0053] Please refer to the attached Figure 8The protective gas input mechanism 7 is fixedly connected to the upper side of the box mechanism 2, which provides power for the input of protective gas. The protective gas input mechanism 7 includes a fixed bottom plate 701 and a cylinder fixed seat 702. The lower side of the fixed bottom plate 701 is fixedly connected to the upper side of the box top plate 204. The lower ends of the cylinder fixed seat 702 are fixedly connected to the upper side of the fixed bottom plate 701. The upper ends of the cylinder fixed seat 702 are fixedly connected with a gas driving cylinder 703. The front side of the gas driving cylinder 703 is fixedly connected with a second driving motor 704. The middle part of the gas driving cylinder 703 is rotatably connected with a transmission shaft 705. The power output end of the second driving motor 704 is fixedly connected to the front end of the transmission shaft 705. The middle part of the transmission shaft 705 is fixedly connected with a plurality of driving input vanes 706.

[0054] Specifically, the protective gas input mechanism 7 is responsible for efficiently delivering protective gas to the inside of the box mechanism 2, ensuring the formation of a stable protective atmosphere during heat treatment. The lower side of the fixed bottom plate 701 is fixedly connected to the upper side of the box top plate 204, providing a stable mounting base. The lower ends of the cylinder fixed seat 702 are fixedly connected to the upper side of the fixed bottom plate 701, ensuring that the gas driving cylinder 703 remains stable during operation. The front side of the gas driving cylinder 703 is fixedly connected with the second driving motor 704 for driving the transmission shaft 705 to rotate. The middle part of the gas driving cylinder 703 is rotatably connected with the transmission shaft 705, ensuring that the transmission shaft 705 can rotate inside the gas driving cylinder 703 and drive the input vanes 706 to rotate. The middle part of the transmission shaft 705 is fixedly connected with a plurality of driving input vanes 706. These vanes can push protective gas from the gas driving cylinder 703 into the side delivery pipe 603 when the transmission shaft 705 rotates.

[0055] Please refer to the accompanying Figure 8 The gas control mechanism 8 is fixedly connected to the middle part of the protective gas input mechanism 7, which is responsible for delivering protective gas to the protective gas input mechanism 7 and controlling and metering the input of gas. The gas control mechanism 8 includes a support frame 801 and a gas input metering control device 802. The lower end of the support frame 801 is fixedly connected to the upper surface of the middle part of the fixed bottom plate 701. The lower side of the gas input metering control device 802 is fixedly connected to the upper end of the support frame 801. The front side of the gas input metering control device 802 is fixedly connected with an external gas input pipe 803.

[0056] Specifically, the gas control mechanism 8 is responsible for accurate metering and control of the protective gas entering the protective gas delivery mechanism 6, ensuring that the protective gas concentration inside the box mechanism 2 is maintained within a predetermined range, thereby providing a stable protective atmosphere for the heat treatment process of the roller 304. The lower end of the support frame 801 is fixedly connected to the middle upper surface of the fixed bottom plate 701, providing stable support for the gas input metering control device 802. The lower side of the gas input metering control device 802 is fixedly connected to the upper end of the support frame 801, ensuring that it can be securely installed in the equipment during operation. The external gas input pipe 803 is fixedly connected to the front side of the gas input metering control device 802, serving as an interface for external protective gas supply. This pipe is responsible for introducing protective gas from the outside into the gas input metering control device 802, and through subsequent metering and control steps, ensuring accurate delivery of the gas. The gas input metering control device 802 is equipped with a flow control valve and a pressure sensor, which accurately controls the flow of protective gas entering the protective gas delivery mechanism 6 by adjusting the flow control valve.

[0057] The gas input metering control device 802 receives instructions from the device control mechanism 10 and dynamically adjusts the opening of the flow control valve based on real-time feedback data from the detection mechanism 9, ensuring that the input amount of protective gas meets the predetermined gas concentration requirements. When the automatic control device 1002 detects that the protective gas concentration inside the box mechanism 2 is lower than the preset value, it sends a signal to the gas input metering control device 802, instructing it to increase the flow of protective gas. After receiving the instruction, the gas input metering control device 802 increases the amount of protective gas entering through the external gas input pipe 803 by adjusting the flow control valve, thereby increasing the gas concentration inside the box mechanism 2. Conversely, when the protective gas concentration is too high, the automatic control device 1002 will instruct the gas input metering control device 802 to reduce the gas flow, and by adjusting the flow control valve, it will reduce the amount of protective gas entering, ensuring that the gas concentration remains within an effective range.

[0058] Please refer to the attached Figure 3 with the attached Figure 6 The detection mechanism 9 is arranged on the box mechanism 2 and the heating mechanism 5 respectively, and its function is to monitor the internal temperature and protective gas concentration of the box mechanism 2 in real time.

[0059] Specifically, a plurality of temperature detection devices 901 are fixedly connected to the upper and lower adjacent sides of the heating box body 502. These temperature detection devices are distributed at different positions of the heating box body 502, ensuring that the temperature conditions of each heating section inside the box mechanism 2 can be comprehensively and uniformly monitored. The temperature detection devices 901 use high-precision thermocouples for detection, which can measure the temperature changes of each heating section inside the heating box body 502 in real time and accurately. The temperature detection devices 901 transmit the measured temperature data to the device control mechanism 10 through electrical connection for analysis and judgment.

[0060] A plurality of gas concentration detection devices 902 are fixedly connected to the upper side of the box top plate 204 and penetrate through the entire box top plate 204. The gas concentration detection devices 902 are distributed at different positions, ensuring that the concentration of the protective gas inside the box mechanism 2 can be comprehensively and uniformly monitored. The gas concentration detection devices 902 can measure the concentration of the protective gas inside the box mechanism 2 in real time. The gas concentration detection devices 902 transmit the measured gas concentration data to the automatic control device 1002 in the device control mechanism 10 through electrical connection for analysis and judgment.

[0061] Please refer to the accompanying Figure 9 The device control mechanism 10 is arranged on the left side of the support base 1. Its function is to automatically control the device and automatically adjust its working parameters according to the preset program.

[0062] Specifically, the device control mechanism 10 is the control center of the entire heat treatment equipment, responsible for coordinating and managing various functional modules of the equipment, ensuring that the equipment operates stably and efficiently according to the preset program and parameters. The console mounting seat 1001 is arranged on the left side of the support base 1 as the fixed base of the automatic control device 1002, the lower side of the automatic control device 1002 is fixedly connected with the front upper surface of the console mounting seat 1001, and the upper side of the automatic control device 1002 is provided with an operation panel 1003 for the operator to start, stop, set parameters and monitor the operation of the equipment. The rear upper surface of the console mounting seat 1001 is fixedly connected with a communication device 1004 for data exchange and remote control with external systems or other equipment.

[0063] The automatic control device 1002 is the main control unit of the equipment, integrating various sensor data processing, actuator control and human-computer interaction functions.

[0064] The automatic control device 1002 is connected to the following components through electrical connection to realize automatic control of the equipment. The first drive motor 404 can control the running speed and direction of the conveying mechanism 3 to ensure the stable movement of the roller 304. The heating device 504 can adjust the heating power to control the temperature inside the box to ensure that the heat treatment process meets the predetermined requirements. The second drive motor 704 can control the running speed of the gas driving cylinder 703 and the driving input vane 706 of the protective gas input mechanism 7 to ensure the stable delivery of the protective gas. The gas input metering control device 802 can adjust the flow of the protective gas to maintain the gas concentration inside the box. The temperature detection device 901 and the gas concentration detection device 902 can monitor the temperature and gas concentration inside the box in real time and feed back the data to the automatic control device 1002. The operation panel 1003 can be used by the operator to input instructions, view real-time data and status information. The communication device 1004 can realize data exchange and remote control with external systems, supporting networked monitoring and management of the equipment.

[0065] Working principle: when using the device, the operator first opens the front pull-out door 205, and then places the rollers 304 to be heat treated in the roller cradles 304 on the conveying mesh belt 303 through automatic equipment or other equipment, and then closes the front pull-out door 205 and waits for the next roller cradle 304 to arrive at the loading position to repeat the above operation.

[0066] After the device is started, the first drive motor 404 starts to run. Through the driving speed reduction device 403, the first drive motor 404 transmits power to the conveying shaft 301, so that the conveying shaft 301 and the conveying roller 302 rotate synchronously, driving the steel conveying mesh belt 303 to move in a loop, thereby pushing the roller cradle 304 and the roller carried thereby to move inside the box mechanism 2.

[0067] With the movement of the roller on the conveying mechanism 3, it enters the heat treatment area set by the heating mechanism 5 in turn. The heating device 504 in the heating mechanism 5 rapidly raises the temperature inside the box through resistance heating, ensuring that the roller surface is uniformly heated to the predetermined heat treatment temperature. The device control mechanism 10 automatically adjusts the power output of the heating device 504 according to the real-time temperature data fed back by the temperature detection device 901, maintains the stability and uniformity of the temperature inside the box, and at the same time, since the roller needs to be heat treated at different temperatures according to the processing time during the heat treatment process, by automatically adjusting the power output of the heating device 504, a heating section with a gentle temperature curve can be formed inside the box, thereby improving the effect of roller repair heat treatment and enabling the equipment to repair heat treatment of rollers of different materials.

[0068] During the heat treatment process, the protective gas input mechanism 7 is started, the second drive motor 704 drives the transmission shaft 705 to rotate, driving the drive input fan blade 706 to uniformly distribute the protective gas to the inside of the box through the side delivery pipe 603. The gas input metering control device 802 accurately adjusts the flow control valve according to the feedback data of the gas concentration detection device 902, maintains the concentration of the protective gas inside the box within the predetermined range, and prevents the roller from being oxidized or other adverse reactions at high temperature.

[0069] The conveying mechanism 3 moves the roller continuously at a set speed under the control of the driving mechanism 4, so that each roller stays in the heating area for enough time to ensure that the heat treatment process achieves the expected repair effect. The rotation speed of the conveying shaft 301 is accurately controlled by the first drive motor 404 through the device control mechanism 10, and the operator can adjust the conveying speed according to the different heat treatment process requirements to adapt to the material characteristics of different rollers.

[0070] The detection mechanism 9 monitors the temperature and protective gas concentration inside the box in real time. The temperature detection device 901 is distributed at multiple positions of the heating box 502 to ensure the comprehensiveness and accuracy of the temperature data; the gas concentration detection device 902 monitors the distribution of the protective gas to prevent uneven or insufficient gas concentration. All detection data is transmitted to the automatic control device 1002 through electrical connection, and the automatic control device 1002 dynamically adjusts the working parameters of the heating device 504 and the gas input metering control device 802 according to the preset control logic, ensuring the stability and efficiency of the entire heat treatment process. During the operation of the device, the opening and closing of the rear pull-out type movable door 205 enables the operator to take out the roller that has completed the heat treatment process from the rear pull-out type movable door 205.

[0071] Through the above workflow, the device can realize continuous, uniform and efficient repair heat treatment of multiple rolls. The conveying mechanism 3 ensures that the rolls are sufficiently heated in the heating area, avoiding the problem of uneven treatment of individual rolls. The heating mechanism 5 provides a stable and uniform high-temperature environment, ensuring that the roll surface and internal material reach the required repair temperature. The coordinated work of the protective gas delivery mechanism 6 and the gas control mechanism 8 maintains a stable protective atmosphere, preventing the roll from oxidizing or other adverse reactions at high temperature, and improving the heat treatment quality. The real-time monitoring of the detection mechanism 9 and the intelligent adjustment of the device control mechanism 10 ensure that the temperature and gas concentration of the device during operation are always in the best state, improving the automation level and the convenience of operation of the device.
