[0002] Roller performance is a key production equipment in the metallurgical, papermaking, textile and other industries. Its performance directly affects production efficiency and product quality. However, during long-term use, the surface of the roller is prone to wear, oxidation and surface defects due to factors such as high temperature, high pressure and friction, which shortens its service life and even affects the normal operation of the production line. In order to extend the service life of the roller and ensure its working performance, roller surface repair has become an indispensable maintenance process. Among them, heat treatment, as an effective surface repair method, can restore the hardness and wear resistance of the roller surface and improve its microstructure by controlling temperature and time, thereby improving the overall performance and durability of the roller.

The outer edge of the conveying roller 302 is provided with a steel conveying mesh belt 303, and the outer surface of the steel conveying mesh belt 303 is fixedly connected with multiple groups of roller brackets 304.

[0044] Specifically, the transmission shaft 301 is fixedly connected to the side plate 202 of the box body, and the transmission support wheel 302 is installed in the middle of the transmission shaft 301 and rotates coaxially with the transmission shaft 301. The outer edge of the transmission support wheel 302 is equipped with a steel transmission mesh belt 303, which has high high temperature resistance and wear resistance and is suitable for long-term operation in a high temperature environment. The steel transmission mesh belt 303 fixes and supports the rollers to be heat-treated through multiple groups of roller brackets 304 on its surface. As the transmission shaft 301 and the transmission support wheel 302 rotate, the steel transmission mesh belt 303 drives the roller bracket 304 and the rollers 304 carried by it to circulate inside the box body mechanism 2. Driven by the driving mechanism 4, the rollers on the roller bracket 304 pass through the heat treatment area set by the heating mechanism 5 in turn, ensuring that the surface of each roller is evenly heated to meet the temperature and time requirements required for repair.

[0045] Please refer to the attached Figure 5 , drive mechanism 4, drive mechanism 4 is arranged on the left side of the transmission mechanism 3 of the support base 1, and its function is to provide power for the transmission mechanism 3, the drive mechanism 4 includes a transmission gear 401, a transmission chain 402, and a driving reduction device 403, the middle part of the transmission gear 401 is fixedly connected to the left end of the transmission shaft 301, the transmission chains 402 are meshed and connected to the outer edge of the transmission gear 401, and the transmission gears 401 are connected to each other through the transmission chain 402, the driving reduction device 403 is fixedly connected to the left side of the box mechanism 2, and a first driving motor 404 is arranged on the lower side of the driving reduction device 403, 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 reduction device 403, and the power output end of the driving reduction device 403 is fixedly connected to the left ends of the transmission shafts 301 on the front and rear sides.

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

[0047] Multiple groups of transmission gears 401 are fixedly connected to the left ends of multiple groups of transmission shafts 301, and transmission chains 402 are respectively meshed and connected to the outer edges of transmission gears 401. The transmission gears 401 are connected to each other through the transmission chains 402. The synchronous movement of multiple groups of transmission gears 401 is achieved through the continuous circulation connection of the transmission chains 402.

[0050] A plurality of heating installation grooves 503 are provided in the middle of the heating box 502, and these installation grooves provide preset positions for fixing the heating device 504. A heating device 504 is fixedly connected inside the heating installation groove 503, and the heating device 504 generates heat by means of resistance heating, which can quickly and evenly increase the temperature inside the box mechanism 2 to reach the temperature level required for the heat treatment of the roller. The device control mechanism 10 can automatically turn on or off the corresponding heating device 504 according to the preset temperature curve, and adjust its power output to meet different heat treatment process requirements. The multiple heating devices 504 in the heating box 502 are evenly distributed, ensuring that the temperature distribution of each area inside the box mechanism 2 is balanced to avoid hot spots or cold spots. It ensures that the roller 304 is heated uniformly during the entire heat treatment process, thereby improving the repair quality.

The gas input main pipe 602 is fixedly connected to the far left and right ends of the side gas input branch pipes 601, serving as the main delivery channel for the protective gas. The side delivery pipeline 603 is used to connect the protective gas input mechanism 7 with the gas input main pipe 602, so that the protective gas can smoothly enter the gas input main pipe 602 from the protective gas input mechanism 7.

[0053] Please refer to the attached Figure 8, a protective gas input mechanism 7, the protective gas input mechanism 7 is fixedly connected to the upper side of the box mechanism 2, and its function is to provide power for the input of the protective gas.

[0055] Please refer to the attached Figure 8 , gas control mechanism 8, the gas control mechanism 8 is fixedly connected to the middle part of the protective gas input mechanism 7, and its function is to transport protective gas to the protective gas input mechanism 7 and control and measure the gas input.

[0056] Specifically, the gas control mechanism 8 is responsible for accurately metering and controlling the protective gas entering the protective gas delivery mechanism 6, ensuring that the concentration of the protective gas 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 pipeline is responsible for introducing the protective gas from the outside into the gas input metering control device 802, and through subsequent metering and control steps, ensuring the accurate delivery of the gas. The gas input metering control device 802 is built-in with a flow control valve and a pressure sensor, and the flow of the protective gas entering the protective gas delivery mechanism 6 is accurately controlled 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 according to the real-time feedback data of the detection mechanism 9 to ensure that the input amount of the protective gas meets the predetermined gas concentration requirements. When the automatic control device 1002 detects that the concentration of the protective gas inside the box mechanism 2 is lower than the preset value, it will send a signal to the gas input metering control device 802 to instruct it to increase the flow of the 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 concentration of the protective gas is too high, the automatic control device 1002 will instruct the gas input metering control device 802 to reduce the gas flow rate, and reduce the amount of protective gas entering by adjusting the flow control valve to ensure that the gas concentration remains within an effective range.

[0062] Specifically, the device control mechanism 10 is the control center of the entire heat treatment equipment, responsible for coordinating and managing the various functional modules of the equipment to ensure that the equipment operates stably and efficiently according to the preset procedures and parameters. The console mounting seat 1001 is arranged on the left side of the support base 1, as a fixed base of the automatic control device 1002, the lower side of the automatic control device 1002 is fixedly connected to 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 operators to start, stop, set parameters and monitor the equipment. The upper surface of the rear side 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 devices.

[0063] The automatic control device 1002 serves as the main control unit of the equipment and integrates 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, control the temperature inside the box, and ensure that the heat treatment process meets the predetermined requirements. The second drive motor 704 can control the running speed of the gas drive cylinder 703 and the drive input fan blade 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 rate 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 the data back to the automatic control device 1002. The operation panel 1003 can be used for the operator to input instructions, view real-time data and status information. The communication device 1004 can realize data exchange and remote control with the external system, and support network monitoring and management of the equipment.

[0065] Working principle: When using the device, the operator first opens the pull-out movable door 205 on the front side, and places the rollers 304 to be heat-treated in the roller brackets 304 on the conveyor belt 303 in sequence through automatic equipment or other equipment, and then closes the pull-out movable door 205 on the front side and waits for the next roller bracket 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 operate. By driving the reduction device 403, the first drive motor 404 transmits power to the transmission shaft 301, so that the transmission shaft 301 and the transmission support wheel 302 rotate synchronously, driving the steel transmission mesh belt 303 to circulate, thereby pushing the roller bracket 304 and the rollers it carries to move inside the box mechanism 2.

[0067] As the rollers move on the conveying mechanism 3, they sequentially enter the heat treatment area set by the heating mechanism 5. The heating device 504 in the heating mechanism 5 quickly raises the temperature inside the box through resistance heating to ensure that the surface of the rollers is evenly heated to reach 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 to keep the temperature inside the box stable and uniform. At the same time, since the rollers need to be heat treated at different temperatures according to the treatment time during the heat treatment process, a heating section with a gentle temperature curve can be formed inside the box by automatically adjusting the power output of the heating device 504, thereby improving the effect of the roller repair heat treatment and enabling the equipment to repair rollers of different materials.

[0068] During the heat treatment process, the protective gas input mechanism 7 is started, and the second drive motor 704 drives the transmission shaft 705 to rotate, driving the drive input blade 706 to evenly 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 to maintain the concentration of the protective gas inside the box within a predetermined range to prevent the roller from being oxidized or other adverse reactions at high temperature.

[0069] The conveying mechanism 3, under the control of the driving mechanism 4, continuously moves the rollers at a set speed, so that each roller stays in the heating area for a sufficient time to ensure that the heat treatment process achieves the expected repair effect. The rotation speed of the conveying shaft 301 is precisely controlled by the first driving motor 404 through the device control mechanism 10. The operator can adjust the conveying speed according to 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 in 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 are transmitted to the automatic control device 1002 through electrical connection. 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 to ensure the stability and efficiency of the entire heat treatment process. During the operation of the device, by opening and closing the rear pull-out movable door 205, the operator can take out the rollers that have completed the heat treatment process from the rear pull-out movable door 205 in sequence.

[0071] Through the above-mentioned working process, the equipment can realize continuous, uniform and efficient repair heat treatment of multiple rollers. The conveying mechanism 3 ensures that the rollers are sufficiently heated in the heating area, avoiding the problem of uneven treatment of a single roller. The heating mechanism 5 provides a stable and uniform high-temperature environment to ensure that the surface and internal materials of the rollers reach the required repair temperature. The protective gas conveying mechanism 6 and the gas control mechanism 8 work together to maintain a stable protective atmosphere, prevent the rollers from oxidizing or other adverse reactions at high temperatures, and improve the quality of heat treatment. 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 equipment are always in the best state during operation, improving the automation level of the equipment and the convenience of operation.
