Description

Technical Field

[0001] This invention relates to the field of mesh belt furnace heat treatment technology, and in particular to a mesh belt furnace heat treatment production line. Background Technology

[0002] A mesh belt furnace is an industrial heat treatment equipment that continuously transports workpieces via a high-temperature resistant mesh belt. It is mainly used for sintering powder metallurgy products, reducing metal powders, and pre-firing, firing, or heat treatment processes of electronic products in a protective atmosphere or air. Its core structure includes the furnace body, mesh belt drive system, and temperature control system. The furnace body is divided into functional zones such as the feeding section, pre-firing section, and sintering section.

[0003] In the existing mesh belt furnace heat treatment production line, the mesh belt tensioning method is mostly fixed or manually adjusted, which can easily cause the mesh belt to run off-center and slip. Long-term production may also lead to mesh belt breakage, resulting in parts falling off or being damaged by collision. For precision parts, mesh belt deviation can also cause contact damage during transmission. At the same time, the production line has slow temperature control response and large heating amplitude fluctuations, which can easily lead to defects such as workpiece deformation, cracking and grain coarsening, ultimately resulting in poor production quality.

[0004] Therefore, this application provides a mesh belt furnace heat treatment production line to meet the demand. Summary of the Invention

Long-term production may also cause mesh belt breakage, resulting in parts falling off or being damaged by collision. For precision parts, mesh belt deviation can also cause contact damage during transmission. At the same time, the production line has slow temperature control response and large heating amplitude fluctuations, which can easily lead to defects such as workpiece deformation, cracking, and grain coarsening, ultimately resulting in poor production quality.

[0008] Optionally, the adaptive correction component includes a flow guide plate fixedly connected to the inner wall of the mesh belt conveyor frame. The flow guide plate is disposed at both ends of the inner wall of the mesh belt conveyor frame, and multiple laser sensors are fixedly connected to the inner wall of the end of the mesh belt conveyor frame.

[0009] Optionally, a micro servo motor is fixedly connected to the end surface of the mesh belt conveyor, a drive tube is fixedly connected to the output end of the micro servo motor, a threaded rod is fixedly connected inside the drive tube, and the other end of the threaded rod is rotatably connected to one end of the mesh belt conveyor.

[0010] Optionally, the surface of the threaded rod is engaged with an internally threaded tube, and the surface of the internally threaded tube is rotatably connected to a plurality of connecting arms, the other end of the plurality of connecting arms being rotatably connected to a drive plate.

[0011] Optionally, the surfaces of the plurality of drive plates are connected to the inner wall of the mesh belt conveyor, wedge blocks are fixedly connected to both ends of the drive plates, and a plurality of pressure sensors are inserted into the surface of the drive plates.

[0012] Optionally, the temperature control and adjustment assembly includes a furnace cavity fixedly connected to the top of the base frame, a connecting cavity fixedly connected to the top of the furnace cavity, a plurality of driving devices fixedly connected to the top of the connecting cavity, and a push rod fixedly connected to the output end of the driving device.

[0013] Optionally, multiple heat insulation plates are fixedly connected to the inner wall of the furnace cavity, and the multiple heat insulation plates divide the interior of the furnace cavity into multiple spaces. Heating tubes are fixedly connected to the surface of the multiple heat insulation plates. Multiple vortex jet heads are fixedly connected to the bottom of the mesh belt conveyor frame, and a radiation screen is fixedly connected to the bottom of the push rod.

[0014] Optionally, the thermal cooling assembly includes a heat insulation plate fixedly connected to the top of the base frame, with multiple air dampers at the end of the heat insulation plate, and a fan fixedly connected to the inner wall of one end of the furnace cavity, with the fan positioned above the air dampers.

[0015] Optionally, a fan duct is fixedly connected to the bottom of the fan, airflow pipes are fixedly connected to both ends of the surface of the fan duct, and multiple branch pipes are fixedly connected to the bottom of the airflow pipes.

[0016] Optionally, a rotary tube is fixedly connected to the inner wall of the furnace cavity, and multiple fins are fixedly connected to the surface of the rotary tube. Multiple nozzles are also fixedly connected to the surface of the rotary tube.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, by setting up an adaptive correction component, the coordinated action of components such as the guide plate, laser sensor, micro servo motor, threaded rod, and drive plate effectively solves the problems of belt deviation, slippage, and breakage that are easily caused by the traditional mesh belt fixing or manual tensioning method. The laser sensor monitors the belt deviation status in real time, and the micro servo motor drives the internal threaded tube and the connecting arm through the threaded rod, which drives the drive plate and wedge block frame to precisely push the mesh belt back to the normal transmission line, realizing adaptive correction of deviation. At the same time, the pressure sensor on the drive plate dynamically monitors the mesh belt tension, and the micro servo motor fine-tunes the position of the drive plate to maintain constant tension, avoiding abnormal tension caused by thermal expansion or wear, reducing the risk of parts falling, collision damage, and contact damage to precision parts, and also extending the service life of the mesh belt, ensuring the continuous and stable operation of the production line.

[0019] By setting up a temperature control and adjustment component, and utilizing the furnace cavity, insulation plate, heating tube, drive device, radiation screen, and vortex jet head, the accuracy and response speed of temperature control in the production line are improved. The insulation plate divides the furnace cavity into multiple independent spaces, and the heating tubes in each space can independently set temperature curves to achieve precise step-by-step control of preheating, heating up, and uniform temperature, adapting to the heat treatment requirements of different parts. At the same time, the drive device drives the push rod to raise and lower the radiation screen, which can flexibly adjust the effective volume of each independent space to adapt to the quenching requirements of workpieces of different sizes. Furthermore, the vortex jet head under the mesh belt conveyor can agitate the airflow in the furnace to ensure uniform temperature distribution.

[0020] By setting up a thermal cooling assembly, and utilizing the cooperation of components such as heat insulation plates, dampers, fans, rotary tubes, fins, and nozzles, rapid and uniform temperature regulation of the furnace cavity is achieved, improving production efficiency. The fins on the surface of the rotary tube can efficiently absorb residual heat in the furnace, and the nozzles can spray coolant in a targeted manner to quickly reduce the temperature of the workpiece. The fans, air ducts, airflow pipes, and branch pipes are linked together, and combined with the openable dampers, a rapid airflow circulation is formed in the furnace. This can quickly exhaust the high-temperature air after heat treatment, and precisely control the cooling rate. Furthermore, the cooperation between the heat insulation plates and dampers can reduce the temperature loss in the furnace and ensure the stability of the cooling process.

However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0037] The mesh belt furnace heat treatment production line provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0038] like Figures 1 to 12 As shown, an embodiment of the present invention provides a mesh belt furnace heat treatment production line, including a base frame 1, a mesh belt conveyor frame 2 rotatably connected to the top of the base frame 1, a loading rack 3 fixedly connected to one end of the base frame 1, a unloading rack 4 fixedly connected to the other end of the base frame 1, a drive motor 5 fixedly connected to one end of the mesh belt conveyor frame 2, an adaptive correction component 6 rotatably connected inside the mesh belt conveyor frame 2, the adaptive correction component 6 being used to correct the misaligned mesh belt, and the adaptive correction component 6 being connected to the mesh belt conveyor frame 2; a temperature control adjustment component 7, the temperature control adjustment component 7 being used to adjust the temperature to adapt to the processing of different parts, and the temperature control adjustment component 7 being connected to the base frame 1; and a thermal energy cooling component 8, the thermal energy cooling component 8 being used to adjust the temperature in the furnace cavity 71, and the thermal energy cooling component 8 being connected to the temperature control adjustment component 7.

[0039] As an implementation method in this embodiment, such as Figures 3 to 6As shown, the adaptive correction component 6 includes a guide plate 61 fixedly connected to the inner wall of the mesh belt conveyor 2. The guide plate 61 is disposed at both ends of the inner wall of the mesh belt conveyor 2. Multiple laser sensors 62 are fixedly connected to the inner wall of the end of the mesh belt conveyor 2. A micro servo motor 63 is fixedly connected to the surface of the end of the mesh belt conveyor 2. A drive tube 64 is fixedly connected to the output end of the micro servo motor 63. A threaded rod 65 is fixedly connected inside the drive tube 64. The other end of the threaded rod 65 is rotatably connected to one end of the mesh belt conveyor 2. An internal threaded tube 66 is meshed with the surface of the threaded rod 65. Multiple connecting arms 67 are rotatably connected to the surface of the internal threaded tube 66. A drive plate 68 is rotatably connected to the other end of the multiple connecting arms 67. The surface of the multiple drive plates 68 is connected to the inner wall of the mesh belt conveyor 2. Wedge blocks 69 are fixedly connected to both ends of the drive plates 68. Multiple pressure sensors are inserted into the surface of the drive plates 68. Sensor 610, through the synergistic action of components such as the flow guide plate 61, laser sensor 62, micro servo motor 63, threaded rod 65, and drive plate 68, effectively solves the problems of belt deviation, slippage, and breakage that are easily caused by traditional mesh belt furnace fixing or manual tensioning methods. Laser sensor 62 monitors the belt deviation status in real time. Micro servo motor 63 drives the internal threaded tube 66 and the connecting arm 67 through threaded rod 65, which in turn drives drive plate 68 and wedge block frame 69 to precisely push the mesh belt back to the normal transmission line, realizing adaptive correction of deviation. At the same time, pressure sensor 610 on drive plate 68 dynamically monitors the mesh belt tension. Micro servo motor 63 finely adjusts the position of drive plate 68 to maintain constant tension, avoiding abnormal tension caused by thermal expansion or wear. This reduces the risk of parts falling, collision damage, and contact damage to precision parts, and also extends the service life of the mesh belt, ensuring the continuous and stable operation of the production line.

[0040] As an implementation method in this embodiment, such as Figures 7 to 10As shown, the temperature control and adjustment assembly 7 includes a furnace cavity 71 fixedly connected to the top of the base frame 1. A connecting cavity 72 is fixedly connected to the top of the furnace cavity 71. Multiple driving devices 73 are fixedly connected to the top of the connecting cavity 72. A push rod 74 is fixedly connected to the output end of the driving device 73. Multiple heat insulation plates 76 are fixedly connected to the inner wall of the furnace cavity 71, dividing the interior of the furnace cavity 71 into multiple spaces. Heating tubes 77 are fixedly connected to the surface of the multiple heat insulation plates 76. Multiple vortex jet heads 78 are fixedly connected to the bottom of the mesh belt conveyor 2. A radiation screen 75 is fixedly connected to the bottom of the push rod 74. The furnace cavity 71, heat insulation plates 76, and heating tubes 77 are used to control the temperature adjustment assembly. The heat pipe 77, drive unit 73, radiation screen 75, and vortex jet head 78 work together to improve the accuracy and response speed of temperature control in the production line. The heat insulation plate 76 divides the furnace cavity 71 into multiple independent spaces. With the help of the heating pipe 77 in each space, the temperature curve can be set independently to achieve precise step-by-step control of preheating, heating, and uniform temperature, which can meet the heat treatment requirements of different parts. At the same time, the drive unit 73 drives the push rod 74 to move the radiation screen 75 up and down, which can flexibly adjust the effective volume of each independent space to meet the quenching requirements of workpieces of different sizes. The vortex jet head 78 under the mesh belt conveyor 2 can stir the airflow in the furnace to ensure uniform temperature distribution.

[0041] As an implementation method in this embodiment, such as Figures 8 to 12 As shown, the thermal energy cooling assembly 8 includes a heat insulation plate 81 fixedly connected to the top of the base frame 1. Multiple air dampers 82 are provided at the ends of the heat insulation plate 81. A fan 83 is fixedly connected to the inner wall of one end of the furnace cavity 71, positioned above the air dampers 82. An air duct 84 is fixedly connected to the bottom of the fan 83. Airflow pipes 85 are fixedly connected to both ends of the surface of the air duct 84. Multiple branch pipes 86 are fixedly connected to the bottom of the airflow pipes 85. A rotary tube 87 is fixedly connected to the inner wall of the furnace cavity 71. Multiple fins 88 are fixedly connected to the surface of the rotary tube 87, and multiple nozzles 89 are also fixedly connected to the surface of the rotary tube 87. The heat insulation plate 81 and the air dampers... The coordination of components such as 82, blower 83, rotary tube 87, fins 88, and nozzle 89 enables rapid and uniform temperature regulation of the furnace cavity 71, improving production efficiency. The fins 88 on the surface of the rotary tube 87 can efficiently absorb residual heat in the furnace, and the nozzle 89 can spray coolant in a targeted manner to quickly reduce the temperature of the workpiece. The blower 83, along with the air duct 84, airflow pipe 85, and branch pipe 86, combined with the openable damper 82, forms a rapid airflow circulation in the furnace, which can quickly discharge the high-temperature air after heat treatment and precisely control the cooling rate. Furthermore, the coordination between the heat insulation plate 81 and the damper 82 can reduce the temperature loss in the furnace and ensure the stability of the cooling process.

[0042] The working principle of the technical solution provided by this invention is as follows:

[0043] When using this device, the workpiece first enters the temperature control and adjustment component 7 via the loading rack 3. The temperature control and adjustment component 7 then starts operating. At this time, the workpiece slowly moves into the furnace cavity 71 via the mesh belt conveyor 2. Subsequently, the drive device 73, fixedly connected to the top of the connecting cavity 72, drives the push rod 74 to move. As the push rod 74 starts moving, the radiation screen 75, fixedly connected to the bottom of the push rod 74, begins to adjust the volume of each independent space in the furnace cavity 71, which is separated by the insulation plate 76, according to the heating temperature of different parts. The lifting and lowering of the screen 75 flexibly adjusts the effective volume inside the furnace cavity 71 to adapt to the quenching requirements of different workpiece sizes. Then, after the heat insulation plate 76 divides the furnace cavity 71 into multiple independent spaces, the heating tubes 77 on the heat insulation plate 76 can be used to independently set the temperature curves of different spaces, so that the multiple independent spaces in the furnace cavity 71 can achieve precise step control of preheating, heating and uniform temperature. Then, in conjunction with the multiple vortex jet heads 78 set below the mesh belt conveyor 2, the air in the furnace cavity 71 is agitated to improve the quenching process of the workpiece.

[0044] After the temperature control component 7 has been running for a long time, when the conveyor belt becomes slack or shifts, the adaptive correction component 6 starts to operate. At this time, multiple laser sensors 62 fixedly connected to the inner wall of the conveyor belt frame 2 constantly detect the conveyor belt. When the conveyor belt shifts, the micro servo motor 63 starts to drive. At this time, the workpiece on the conveyor belt frame 2 comes into contact with the elastic guide plate 61 during the conveying process, protecting the workpiece, reducing damage, improving the ability to deal with problems, and maintaining the production speed. With the drive of the micro servo motor 63, the drive tube 64 fixedly connected to the output end of the micro servo motor 63 drives the threaded rod 65 to rotate. With the rotation of the threaded rod 65, the meshing internal threaded tube 66 begins to rotate. The threaded rod 65 moves, and as the internal threaded tube 66 moves, the multiple connecting arms 67 rotatably connected to the surface of the internal threaded tube 66 drive the drive plate 68 to extend outward. As the multiple drive plates 68 extend outward synchronously, they expand the mesh belt. The edge of the mesh belt then begins to contact the wedge bracket 69 at the end of the drive plate 68. The rotating drive plate 68 then drives the wedge bracket 69 to push the mesh belt little by little onto the normal track, solving the lateral deviation of the mesh belt. At the same time, the pressure sensor 610 on the drive plate 68 monitors the mesh belt tension in real time and dynamically fine-tunes the position of the drive plate 68 through the micro servo motor 63 to maintain constant tension and avoid tension relaxation or over-tightening due to thermal expansion or wear.

[0045] After the workpiece has undergone heat treatment, the heat cooling assembly 8 begins to operate. At this time, the fins 88 fixedly connected to the rotary tube 87 begin to absorb part of the heat from the heat treatment in the furnace cavity 71. Simultaneously, multiple nozzles 89 on the rotary tube 87 begin to spray coolant onto the workpiece. As the workpiece moves on the mesh belt conveyor 2 to the independent space at the bottom of the fan 83, the damper 82 at the end of the heat insulation plate 81 begins to open. With the opening of the damper 82, the fan 83 installed above the damper 82 begins to operate. At this time, the suction force generated by the rotation of the fan 83 is transmitted to the air duct 84. The air duct 84 begins to absorb the airflow in the independent space. At the same time, multiple airflow pipes 85 fixedly connected to the end of the air duct 84 begin to work with the branch pipes 86 to absorb heat from the space in each furnace cavity 71 and then discharge it through the fan 83. The hot air in the furnace cavity 71 is quickly drawn to the outside and then blown back into the furnace through the damper 82, forming a rapid circulation, accelerating the temperature regulation in the furnace and increasing production efficiency.
