Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mesh belt heat treatment furnace, especially to a material uniform distribution mechanism for mesh belt heat treatment furnace. BACKGROUND

[0002] The mesh belt heat treatment furnace is an industrial furnace for metal material heat treatment, which continuously sends workpieces into the furnace through the mesh belt conveying system for heating, heat preservation and cooling heat treatment process. Its main structure includes mesh belt conveying system, heating system, cooling system, atmosphere control system and electrical control system. The mesh belt conveying system is composed of high-temperature-resistant stainless steel mesh belt and driving device, which is responsible for conveying workpieces from the front of the furnace to each processing area in the furnace, and then conveying the processed workpieces out of the furnace. The heating system usually adopts electric heating or gas heating method, which can raise the temperature in the furnace to the required range to meet the requirements of different heat treatment processes.

[0003] In modern industrial production, the mesh belt heat treatment furnace is a key equipment to improve the performance of metal materials, which is often used for efficient heat treatment of cylindrical metal pipes and other products. However, the current mesh belt heat treatment furnace lacks effective material uniform distribution feeding mechanism when in use, which causes the cylindrical metal pipes to roll and stack together due to gravity when feeding. When these stacked pipes enter the heat treatment furnace for electric heating treatment, some areas cannot fully contact the heat source due to the shielding of the contact surface, resulting in uneven heating. This uneven heating not only reduces the effect of heat treatment and affects the overall performance of the product, but also may cause the product to be a waste product, increase production cost and reduce production efficiency.

[0004] Therefore, we propose a material uniform distribution mechanism for mesh belt heat treatment furnace to solve the above-mentioned problems. SUMMARY

[0005] The purpose of this section is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the utility model name to avoid obscuring the purpose of this section, the abstract of the specification and the utility model name. Such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] Therefore, the utility model aims to provide a material uniform distribution mechanism for mesh belt heat treatment furnace, which can solve the problem of uneven heating of cylindrical metal pipes, product performance decline, waste rate increase and production efficiency reduction caused by the lack of effective material uniform distribution feeding mechanism in the existing mesh belt heat treatment furnace.

[0007] In order to solve the above technical problems, the utility model provides a material uniform distribution mechanism for mesh belt heat treatment furnace adopts the following technical scheme: including the furnace body, the one side of furnace body is installed with material distribution unit, material distribution unit includes material transmission assembly, one end of material transmission assembly is provided with material distribution assembly, material distribution assembly includes drive base, the top of drive base is installed with material distribution part;

[0008] The top of the drive base is provided with a discharge hopper, and the side of the drive base close to the discharge hopper is drivingly connected with an output shaft.

[0009] Optionally, the material distribution part includes a fixed base plate, the fixed base plate is fixedly connected to the top side of the discharge hopper, a wiping soft pad is laid on the top of the fixed base plate, a first material leakage hole is formed through the fixed base plate and the wiping soft pad, and the first material leakage hole is located directly above the discharge hopper.

[0010] Optionally, a rotating base plate is arranged on the top of the fixed base plate, the rotating base plate is drivingly connected with the output shaft, a plurality of second material leakage holes are formed through the top of the rotating base plate in a circumferential array, and the second material leakage holes are matched with the first material leakage hole in structure.

[0011] Optionally, the material transmission assembly includes an inclined rolling frame, a metal limiting frame is arranged at one end of the inclined rolling frame, and a guide sliding block is arranged on each side of one end of the metal limiting frame.

[0012] Optionally, an annular groove is formed at one end of the inclined rolling frame, the annular groove is matched with the rotating base plate in structure, the annular groove is transitionally fitted with the rotating base plate, plug-in grooves are formed on both sides of one end of the inclined rolling frame close to the annular groove, the plug-in grooves are matched with the metal limiting frame in structure, and the plug-in grooves are plug-in fitted with the metal limiting frame.

[0013] Optionally, a guide sliding groove is formed on each side of the plug-in groove, a limiting baffle is arranged on the outside of the guide sliding groove, and a compression spring is further connected between the limiting baffle and the guide sliding block.

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

[0015] 1. The material uniform distribution mechanism designed in this scheme, through the cooperation of the inclined roller frame and the metal limiting frame in the material conveying component, can effectively limit and convey cylindrical metal pipes. The insertion and cooperation between the insertion plate groove at one end of the inclined roller frame and the metal limiting frame, as well as the synergistic effect of the guide slide, the limiting baffle and the compression spring, allow the metal limiting frame to elastically contract when not in use, while providing stable elastic limiting when conveying pipes. This not only facilitates the conveying of pipes, but also effectively avoids the disorderly rolling of cylindrical metal pipes during the conveying process, improves the orderliness and accuracy of material feeding, and lays the foundation for subsequent uniform distribution processing.

[0016] 2. The material distribution mechanism designed in this scheme, through the structural design of the fixed base plate and the rotating base plate in the material distribution component, can achieve uniform distribution and cleaning of cylindrical metal pipes. The rotating base plate rotates continuously under the drive of the output shaft, so that the pipes rolling to the second discharge port are evenly distributed between the fixed base plate and the rotating base plate. By wiping the soft pad laid on the top of the fixed base plate, the outer surface of the rotating cylindrical metal pipes can be wiped to remove dust and other impurities adhering to the surface of the cylindrical metal pipes. When the second discharge port is aligned with the first discharge port, the cleaned cylindrical metal pipes accurately roll onto the conveyor belt of the furnace body through the discharge hopper, ensuring the uniform distribution of cylindrical metal pipes in the heat treatment area, avoiding stacking and adhesion, thereby significantly improving the stability and consistency of the heat treatment process, and improving product quality and production efficiency.

Detailed Implementation

[0024] 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.

[0025] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a material uniform distribution mechanism for a mesh belt heat treatment furnace, including a furnace body 1. A material distribution unit 2 is installed on one side of the furnace body 1. The material distribution unit 2 includes a material conveying component 3. A material distribution component 4 is provided at one end of the material conveying component 3. The material distribution component 4 includes a drive base 5. A material distribution component 6 is installed on the top of the drive base 5. A discharge hopper 7 is installed on the top of the drive base 5. An output shaft 8 is connected to the side of the drive base 5 near the discharge hopper 7. Through the structural design of the insertion plate groove 18 and the metal limiting frame 15, and the cooperation of the guide slide 19, the limiting baffle 20, and the compression spring 21, the metal limiting frame 15 connected to one end of the inclined roll frame 14 can be elastically adjusted. The metal limiting frame 15 can be used when not in use. In certain situations, it can elastically retract inside the insert slot 18. When the cylindrical metal pipe is conveyed inside the inclined roll frame 14, the metal limiting frame 15 can elastically limit the cylindrical metal pipe, making it convenient for the cylindrical metal pipe conveyed inside the inclined roll frame 14 to roll onto the material distribution component 6. The material distribution component 6 includes a fixed base plate 9, which is fixedly connected to the top side of the discharge hopper 7. A wiping pad 10 is laid on the top of the fixed base plate 9, and a first discharge port 11 is opened through between the fixed base plate 9 and the wiping pad 10. The first discharge port 11 is located directly above the discharge hopper 7. Through the wiping pad 10 laid on the top of the fixed base plate 9, the outer surface of the rotating and rolling cylindrical metal pipe can be wiped, and the dust adhering to the outer surface of the cylindrical metal pipe can be wiped and cleaned.

[0026] A rotating base plate 12 is mounted on the top of the fixed base plate 9. The rotating base plate 12 is connected to the output shaft 8 via a transmission connection. Multiple sets of second discharge ports 13 arranged in a circular array are also provided on the top of the rotating base plate 12. The second discharge ports 13 are structurally matched with the first discharge ports 11. Through the second discharge ports 13 on the top of the rotating base plate 12, and because the second discharge ports 13 and the first discharge ports 11 are structurally matched, when the second discharge ports 13 and the first discharge ports 11 are aligned, the cylindrical metal pipes that have undergone wiping and cleaning can roll through the discharge hopper 7 onto the conveyor belt of the furnace body 1, ensuring that multiple sets of... The cylindrical metal tubes are evenly distributed before and after entering the heat treatment area to avoid stacking or adhesion between them. The material conveying component 3 includes an inclined roller frame 14. A metal limiting frame 15 is installed at one end of the inclined roller frame 14. Guide sliders 16 are respectively provided on both sides of one end of the metal limiting frame 15. By adding the metal limiting frame 15 to one end of the inclined roller frame 14, the cylindrical metal tubes rolling down from one end of the inclined roller frame 14 can be limited and blocked, making it convenient for the cylindrical metal tubes conveyed inside the inclined roller frame 14 to roll down onto the material distribution component 6.

[0027] An annular groove 17 is provided at one end of the inclined drop frame 14. The annular groove 17 matches the structure of the rotating base plate 12, and the annular groove 17 and the rotating base plate 12 are in a transition fit. Insertion slots 18 are provided on both sides of the end of the inclined drop frame 14 near the annular groove 17. The insertion slots 18 match the structure of the metal limiting frame 15, and the insertion slots 18 and the metal limiting frame 15 are in a plug-in fit. Through the plug-in fit structure between the insertion slots 18 and the metal limiting frame 15, the metal limiting frame 15 can be fixedly connected to one end of the inclined drop frame 14. Guides are provided on both sides of the insertion slots 18. The guide slide 19 has a limit baffle 20 installed on its outer side. A compression spring 21 is also connected between the limit baffle 20 and the guide slider 16. Through the cooperation of the guide slide 19, the limit baffle 20 and the compression spring 21, the metal limit frame 15 connected to one end of the inclined roll frame 14 can be elastically adjusted. When not in use, the metal limit frame 15 can be elastically retracted inside the insert slot 18. When the inclined roll frame 14 is conveying cylindrical metal pipes, the metal limit frame 15 can elastically limit the cylindrical metal pipes.

[0028] Working Principle: The material uniform distribution mechanism designed in this scheme mainly consists of a material conveying component 3 and a material distribution component 4. The material conveying component 3 includes an inclined roller frame 14 and a metal limiting frame 15. The metal limiting frame 15 is equipped with guide sliders 16 on both sides of one end, which cooperate with the insertion slots 18 opened on both sides of one end of the inclined roller frame 14. Since the insertion slots 18 and the metal limiting frame 15 are structurally matched and the two are in a plug-in fit, the metal limiting frame 15 can be limited and connected to the inclined roller. At one end of the drop frame 14, the inclined drop frame 14, through the coordinated action of the guide slide 19, the limiting baffle 20 and the compression spring 21, can elastically adjust the metal limiting frame 15 connected to one end of it. When not in use, the metal limiting frame 15 can elastically retract into the insert plate groove 18. When conveying cylindrical metal pipes, the metal limiting frame 15 can elastically limit the pipes, making it convenient for the cylindrical metal pipes conveyed inside the inclined drop frame 14 to roll onto the material distribution component 6.

[0029] The material uniform distribution mechanism of this solution achieves uniform material distribution by adding a material distribution component 6 to the top of the drive base 5. The material distribution component 6 mainly consists of a fixed base plate 9 and a rotating base plate 12. The rotating base plate 12 is connected to the output shaft 8 by a transmission. Therefore, when the drive base 5 is powered on, it can drive the rotating base plate 12 to rotate on the top of the fixed base plate 9. When the cylindrical metal tube rolls down through the metal limit frame 15 into the interior of the second discharge port 13, the rotating base plate 12 can drive the rolling cylindrical metal tube to rotate between the fixed base plate 9 and the rotating base plate 12. At the same time, the wiping pad 10 laid on the top of the fixed base plate 9 can wipe the outer surface of the rotating cylindrical metal tube, effectively removing the dust adhering to the outer surface of the tube.

[0030] The material uniform distribution mechanism of this scheme uses a first material discharge port 11 that runs through the fixed base plate 9 and the wiping pad 10, and the first material discharge port 11 is located directly above the discharge hopper 7. When the second material discharge port 13 is aligned with the first material discharge port 11, the cylindrical metal tubes that have been wiped and cleaned can roll down through the discharge hopper 7 onto the conveyor belt of the furnace body 1. Since the rotation speed of the rotating base plate 12 remains constant, the multiple sets of second material discharge ports 13 that run through its top can uniformly discharge multiple sets of cylindrical metal tubes. This ensures that multiple sets of cylindrical metal tubes are evenly distributed before and after entering the heat treatment area, avoiding stacking or adhesion between the tubes, thereby improving the stability and consistency of the subsequent heat treatment process of the cylindrical metal tubes.

[0031] 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.
