Description

Technical Field

[0001] This utility model relates to the field of mesh belt normalizing furnace technology, and in particular to a material conveying mechanism for a mesh belt normalizing furnace. Background Technology

[0002] A mesh belt normalizing furnace is a continuous industrial heat treatment device used for normalizing metallic materials. It typically consists of a heating zone, a holding zone, a cooling zone, and a conveying system. The equipment uses a mesh belt to transport the workpieces, ensuring they are uniformly heated and held at a constant temperature within the furnace according to set process parameters. Normalizing is achieved through a suitable cooling method. Normalizing is an important process for improving the uniformity of metal structure, eliminating internal stress, and improving mechanical properties, and is widely used in industries such as steel, automotive, and machinery manufacturing. Mesh belt normalizing furnaces offer advantages such as high automation, high production efficiency, precise temperature control, and uniform heating, making them suitable for mass production scenarios.

[0003] In modern industrial production, mesh belt heat treatment furnaces are widely used for the efficient heat treatment of products such as cylindrical metal tubes, as important equipment for improving the properties of metal materials. However, in actual use, existing mesh belt heat treatment furnaces lack a complete material transfer mechanism, which prevents the cylindrical metal tubes after normalizing from being automatically conveyed upwards. Manual handling is often required, affecting production efficiency and safety. Furthermore, the cooling effect on the surface of the metal tubes during transfer is inadequate, potentially leading to uneven thermal stress and a decline in surface quality.

[0004] Therefore, there is an urgent need to develop a new type of transmission mechanism that integrates material transfer and effective cooling functions to meet the needs of efficient and continuous production and further improve product quality and production safety. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a material conveying mechanism for a mesh belt normalizing furnace, which can solve the problems of uneven thermal stress and decreased surface quality caused by the lack of a perfect material transfer mechanism in existing mesh belt heat treatment furnaces, which leads to the inability to automatically convey cylindrical metal pipes after normalizing and poor surface cooling treatment during the transfer process.

[0007] To solve the above technical problems, this utility model provides a material conveying mechanism for a mesh belt normalizing furnace, which adopts the following technical solution: it includes a mesh belt normalizing furnace, a material conveying unit is installed on one side of the mesh belt normalizing furnace, the material conveying unit includes a first conveying component, a second conveying component is provided on one side of the first conveying component, the first conveying component includes a material transfer component, and an air-cooled radiator is provided on the top of the material transfer component.

[0008] The second conveying component includes a chain conveyor, and a discharge rack is provided on one side of the top of the chain conveyor.

[0009] Optionally, the material transfer component includes a protective housing, with bearing seats provided on both outer sides of the protective housing. A transmission wheel is connected to one side of one set of bearing seats, and a transfer roller is connected between the two sets of bearing seats. The transfer roller is installed inside the protective housing.

[0010] Optionally, a first guide plate is inclinedly provided on one side of the opening of the protective shell, a second guide plate is inclinedly provided on the bottom of the protective shell, and an outlet is also provided on the bottom side of the protective shell near the second guide plate.

[0011] Optionally, the first guide plate is located directly below the discharge port of the mesh belt normalizing furnace, and the discharge port is located directly above the discharge port of the chain conveyor.

[0012] Optionally, the air-cooled radiator includes a support frame, and a blower is provided on the top of the support frame.

[0013] Optionally, the top of the support frame is provided with an air inlet, and a cold water pipe is installed inside the air inlet. A circulating pump is installed at both ends of the cold water pipe, and the circulating pump is installed on both sides of the outside of the support frame.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The material conveying mechanism designed in this scheme, through the coordinated operation of the first conveying component and the second conveying component, can realize the automatic upward conveying of cylindrical metal pipes after normalizing treatment. The material transfer component in the first conveying component can perform preliminary transfer of the metal pipes, and with the interaction of the protective shell, bearing seat, transmission wheel and transfer roller, it ensures that the metal pipes smoothly enter the subsequent conveying stage. The chain plate conveyor and discharge rack in the second conveying component can further guide and transport the metal pipes accurately to the designated position. This process effectively avoids the problem of relying on manual handling in traditional processes, greatly improves production efficiency, reduces labor intensity, and ensures the safety and reliability of the production process, adapting to the needs of modern industrial automation and continuous production.

[0016] 2. The material transfer mechanism designed in this scheme, through the air-cooled radiator installed on the top of the material transfer component, can quickly and uniformly cool down the cylindrical metal pipes after normalizing. The blower in the air-cooled radiator works in conjunction with the air inlet, chilled water pipes and circulating pump. First, the blower draws in outside air to form a cooling airflow, and then the cooling water circulating in the chilled water pipes cools the airflow. When the cooled airflow blows on the surface of the metal pipes, it can quickly remove the high temperature heat from the surface. This process effectively avoids problems such as uneven thermal stress and surface quality degradation caused by untimely cooling, ensuring the stability and consistency of product quality after normalizing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Refer to Figures 1 to 7 This utility model provides an embodiment of a material conveying mechanism for a mesh belt normalizing furnace, comprising a mesh belt normalizing furnace 1, a material conveying unit 2 installed on one side of the mesh belt normalizing furnace 1, the material conveying unit 2 including a first conveying component 3, a second conveying component 4 disposed on one side of the first conveying component 3, the first conveying component 3 including a material transfer component 5, and an air-cooled radiator 6 disposed on the top of the material transfer component 5, the second conveying component 4 including a chain conveyor 7, and a discharge rack 8 disposed on one side of the top of the chain conveyor 7. Through the cooperative use of the first conveying component 3 and the second conveying component 4, preliminary transfer processing can be performed on the cylindrical metal pipes after normalizing inside the mesh belt normalizing furnace 1, and the cylindrical metal pipes after normalizing inside the mesh belt normalizing furnace 1 can be conveyed upwards. This process realizes the upward transport of the cylindrical metal pipes after normalizing. The automatic upward conveying of pipe fittings avoids the problem of relying on manual handling in traditional processes. The material transfer component 5 includes a protective shell 9, with bearing seats 10 on both sides of the outer shell 9. One side of one set of bearing seats 10 is connected to a transmission wheel 11, and a transfer roller 12 is connected between the two sets of bearing seats 10. The transfer roller 12 is installed inside the protective shell 9. By adding bearing seats 10 on both sides of the outer shell 9, the transfer roller 12 can be rotatably connected to the inside of the protective shell 9. When the transmission wheel 11 connected to one side of one set of bearing seats 10 is connected to the drive motor through a transmission belt or other medium, the drive motor can drive the transmission wheel 11 to rotate inside the protective shell 9. The clockwise rotating transfer roller 12 can transfer the cylindrical metal pipe fittings discharged into the protective shell 9.

[0028] A first guide plate 13 is inclinedly arranged on one side of the opening of the protective shell 9, and a second guide plate 14 is inclinedly arranged on the bottom of the protective shell 9. An outlet 15 is also opened on the bottom side of the protective shell 9 near the second guide plate 14. The first guide plate 13 and the second guide plate 14 inclinedly arranged on the protective shell 9 can play a good guiding and rolling assistance role for the cylindrical metal pipe during transportation. The first guide plate 13 is located directly below the discharge port of the mesh belt normalizing furnace 1, and the outlet 15 is located directly above the discharge port of the chain conveyor 7. The first guide plate 13 located directly below the discharge port of the mesh belt normalizing furnace 1 plays a role in guiding and stabilizing the initial falling direction of the cylindrical metal pipe. The outlet 15 located directly above the discharge port of the chain conveyor 7 can ensure that the cylindrical metal pipe after preliminary cooling or transfer can smoothly and accurately enter the chain conveyor 7 to complete the subsequent conveying process.

[0029] The air-cooled radiator 6 includes a support frame 16, with a blower 17 mounted on top of the support frame 16. The blower 17, mounted on top of the support frame 16, provides air cooling for the cylindrical metal pipes transported inside the material transfer component 5. An air inlet 18 is located on top of the support frame 16, and a cold water pipe 19 is installed inside the air inlet 18. Circulating pumps 20 are installed at both ends of the cold water pipe 19, and are mounted on both sides of the support frame 16. The air-cooled radiator 6 utilizes the blower 17 to cool the cylindrical metal pipes transported inside the material transfer component 5. The cold water pipe fitting 19 is equipped with a circulating delivery pump 20 at both ends. When the blower 17 runs and generates a cooling airflow, the airflow will come into contact with the cold water pipe fitting 19 when it passes through the air inlet 18. Since the circulating delivery pump 20 drives the cooling water to circulate in the cold water pipe fitting 19, the temperature of the cooling airflow can be effectively reduced during the heat exchange process with the cold water pipe fitting 19. This process ensures that the cooling airflow blowing on the surface of the cylindrical metal pipe fitting has sufficient cooling capacity, thereby achieving rapid and uniform cooling of the high-temperature metal pipe fitting and avoiding quality problems of the metal pipe fitting caused by high temperature.

[0030] Working Principle: The material conveying mechanism designed in this scheme mainly consists of a first conveying component 3 and a second conveying component 4. The first conveying component 3 includes a material transfer part 5 and an air-cooled radiator 6. The material transfer part 5, through the cooperation of the protective shell 9, bearing seat 10, transmission wheel 11, and transfer roller 12, can initially transfer the cylindrical metal pipes after normalizing in the mesh belt normalizing furnace 1. After the cylindrical metal pipes after normalizing come out of the discharge port of the mesh belt normalizing furnace 1, they will fall directly onto the transfer roller 12 of the material transfer part 5. The transfer roller 12 is located on the bearing seat 10. Supported and driven by the transmission wheel 11, the metal pipe can be smoothly transferred into the protective shell 9 and slide down along the first guide plate 13. The first guide plate 13 is inclined and set on one side of the opening of the protective shell 9. Its position is exactly below the discharge port of the mesh belt furnace 1, which can ensure that the metal pipe enters the material transfer component 5 accurately. The metal pipe will continue to slide inside the protective shell 9 and finally be discharged from the discharge port 15. The discharge port 15 is located directly above the discharge port of the chain conveyor 7, which provides precise positioning for the metal pipe to enter the second conveying component 4.

[0031] The second conveying component 4 in this scheme consists of a chain conveyor 7 and a discharge rack 8. It can transport and guide the normalized cylindrical metal pipes upwards and discharge them. As a common conveying equipment, the chain conveyor 7 has good stability and load-bearing capacity, and can adapt to the conveying needs of metal pipes in high-temperature environments. It smoothly transports the metal pipes discharged from the material transfer component 5 upwards. During this process, the metal pipes are gradually lifted to the required height for subsequent processing or treatment. When the metal pipes are transported to the top of the chain conveyor 7, the discharge rack 8 begins to function. The discharge rack 8 is set on one side of the top of the chain conveyor 7 and can guide and discharge the transported metal pipes, so that the metal pipes can be discharged in an orderly manner, which is convenient for the connection of subsequent processes. Through the coordinated operation of the first conveying component 3 and the second conveying component 4, the entire material conveying mechanism realizes the automatic upward transport of the normalized cylindrical metal pipes, avoiding the problem of relying on manual handling in traditional processes, thereby greatly improving production efficiency and reducing labor intensity, and ensuring a safer and more reliable production process.

[0032] The material transfer mechanism designed in this scheme utilizes a wind-cooled radiator 6 mounted on top of the material transfer component 5. This radiator 6 consists of a support frame 16 and a blower 17. Through the coordinated operation of the blower 17, air inlet 18, chilled water pipe 19, and circulating pump 20, the heat dissipation airflow is cooled. The chilled water pipe 19 is a special pipe structure that can hold cooling water. The cooling water is driven by the circulating pump 20 and circulates within the chilled water pipe 19. The circulating pump 20 is installed on both sides of the support frame 16 and connected to the chilled water pipe 19 via pipes, forming a closed cooling water circulation system. When the blower 17 is running, the generated heat dissipation airflow enters the support frame 16 through the air inlet 18. At this point, the cooling airflow comes into contact with the cold water pipe 19. Since cooling water is constantly circulating inside the cold water pipe 19, the temperature of the cooling airflow is effectively reduced during the heat exchange process with the cold water pipe 19. The cooled airflow then blows onto the surface of the normalized cylindrical metal pipe, which can quickly remove the high temperature heat from the surface of the metal pipe. This cooling method not only improves the heat dissipation efficiency, but also ensures that the temperature of the cooling airflow is relatively stable, avoiding the problem of inconsistent cooling effect of the metal pipe caused by airflow temperature fluctuations. This effectively avoids the problem of uneven thermal stress and surface quality degradation caused by untimely cooling during the transportation of the normalized cylindrical metal pipe, ensuring the stability and consistency of the quality of the normalized product.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
