AI Technical Summary
In existing technologies, excessive material accumulation on one side of the conveyor belt can cause the belt to shift, resulting in material falling off the other side.
The design employs a combination of transmission mechanism and pusher guide. The material is evenly distributed by the motor-driven mesh belt drive and pusher plate movement. The support rollers lift the end face of the mesh belt to form an arc shape, which avoids material accumulation and prevents the mesh belt from deviating.
This achieves uniform material distribution on the conveyor belt, avoids belt deviation and material drop, and improves conveying efficiency and safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of annealing furnace technology, specifically to a mesh belt feeding structure for an annealing furnace. Background Technology
[0002] An annealing furnace is a heat treatment device used for annealing metallic materials. It primarily improves the internal structure of the metal by heating, holding, and slowly cooling it, thereby adjusting the material's mechanical properties (such as hardness, strength, and toughness) and processing properties (such as machinability and stamping ability). It is widely used in industries such as steel, non-ferrous metals, machinery manufacturing, automotive, and aerospace.
[0003] In existing technology, the materials to be processed are generally conveyed to the annealing furnace by a mesh belt. However, before the mesh belt conveys the materials, the materials are transferred to the mesh belt manually using tools. This may result in the materials not being evenly distributed on the mesh belt. There may be too much material piled up on one side of the mesh belt, which may cause the mesh belt to shift and the material on the other side of the mesh belt may fall off. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mesh belt feeding structure for annealing furnaces, which solves the problem mentioned in the background art that excessive material accumulation on one side of the mesh belt may cause the mesh belt to shift and material on the other side of the mesh belt to fall off.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a mesh belt feeding structure for an annealing furnace, applied to the annealing furnace body, wherein the annealing furnace body has a feeding port, and further includes two support frames, a transmission mechanism and a pushing guide. The two support frames are disposed on one side of the annealing furnace body, the transmission mechanism is disposed on the two support frames for conveying materials, and the pushing guide is disposed at the top of the two support frames for pushing materials from both sides toward the middle.
[0008] Furthermore, the transmission mechanism includes a first motor, a drive shaft, a drive roller, two connecting plates, an extension plate, a mounting plate, a driven shaft, a driven roller, a first mesh belt, and an auxiliary anti-deviation component. The first motor is mounted on the outer wall of one of the support frames. Both ends of the drive shaft are rotatably connected to the side walls of the two support frames, respectively. One end of the drive shaft is coaxially connected to the output end of the first motor. The drive roller is fitted onto the drive shaft, and the drive roller and the drive shaft are coaxially and fixedly connected. One end of each of the two connecting plates is fixedly connected to the side walls of the two support frames, respectively. One end of the extension plate is fixedly connected to the connecting plate. One end of the mounting plate is fixedly connected to the other end of the extension plate. Both ends of the driven shaft are rotatably connected to the side walls of the two mounting plates, respectively. The driven roller is fitted onto the driven shaft and coaxially and fixedly connected to the driven shaft. The first mesh belt is tensioned and fitted onto the drive roller and the driven roller. The auxiliary anti-deviation component is disposed on the mounting plate and is used to support and drive the two ends of the first mesh belt to tilt upwards.
[0009] Furthermore, the anti-deviation assembly includes a fixed base, a second motor, a rotating rod, a rotating shaft, and a support roller. One end of the fixed base is fixedly connected to the outer wall of the mounting plate. The second motor is mounted on the outer wall of the fixed base. The fixed base has a rotating groove that mates with the rotating rod. One end of the rotating rod is disposed in the rotating groove and slidably engages with it. The rotating shaft passes through one end of the rotating rod and is fixedly connected to it. Both ends of the rotating shaft are rotatably connected to the two inner walls of the rotating groove, respectively. The output end of the second motor is fixedly connected to one end of the rotating shaft. The support roller is sleeved on the rotating rod and rotatably connected to it coaxially.
[0010] As a further embodiment of this solution, the material pushing guide includes two fixed plates, two electric telescopic rods, and a material pushing plate. The bottom ends of the two fixed plates are respectively fixedly connected to the top ends of the two support frames. Two electric telescopic rods are symmetrically installed on the fixed plates. One end of each of the two electric telescopic rods is fixedly connected to one end of the material pushing plate. The bottom end of the material pushing plate is attached to the top end of the first mesh belt.
[0011] As a further step in this solution, the top of the first mesh belt is higher than the inner bottom wall of the feed inlet, and the width of the first mesh belt is smaller than the width of the feed inlet.
[0012] Based on the aforementioned scheme, the driven roller is located at the center of the first mesh belt, and the distance between the outer end faces of the two support rollers is greater than the width of the first mesh belt.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a mesh belt feeding structure for an annealing furnace, which has the following beneficial effects:
[0015] In this invention, through the cooperation of the transmission mechanism and the pusher guide, the first motor drives the first mesh belt to move under the support of the drive roller and the driven roller, stacking the material on the first mesh belt. Then, the bottom ends of the two pusher plates are driven by the telescopic rod to move towards each other along the upper end face of the first mesh belt, thus bringing the scattered material accumulated on the edge of the first mesh belt towards the center. Afterward, the material is conveyed with the transmission of the first mesh belt. The second motor drives the support roller to rotate, causing the two ends of the first mesh belt to tilt upward, making the end face of the first mesh belt arc-shaped. This can gather the material towards the center of the first mesh belt, preventing the material from accumulating at one end of the first mesh belt and causing the first mesh belt to shift in the direction of material accumulation. This prevents the first mesh belt from shifting and causing the material to fall. Therefore, the mesh belt feeding structure of this annealing furnace solves the problem in the prior art where too much material accumulates on one side of the mesh belt, which may cause the mesh belt to shift and the material on the other side of the mesh belt to fall.

[0021] 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.
[0022] Example
[0023] Please see Figures 1 to 4 A mesh belt feeding structure for an annealing furnace is applied to the annealing furnace body 1. The annealing furnace body 1 is provided with a feeding port 2 and also includes two support frames 3, a transmission mechanism and a pushing guide. The two support frames 3 are arranged on one side of the annealing furnace body 1.
[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the transmission mechanism is mounted on two support frames 3 for conveying materials. The transmission mechanism includes a first motor 4, a drive shaft 5, a drive roller 6, two connecting plates 7, an extension plate 8, a mounting plate 9, a driven shaft 10, a driven roller 11, a first mesh belt 12, and auxiliary anti-deviation components. The first motor 4 is mounted on the outer wall of one support frame 3. Both ends of the drive shaft 5 are rotatably connected to the side walls of the two support frames 3 respectively. One end of the drive shaft 5 is coaxially connected to the output end of the first motor 4. The drive roller 6 is mounted on the drive shaft 5, and the drive roller 6 and the drive shaft 5 are coaxially fixedly connected. One end of the two connecting plates 7 is fixedly connected to the side walls of the two support frames 3 respectively. One end of the extension plate 8 is fixedly connected to the connecting plate 7. The connecting plate 7 and the extension plate 8 form an L-shape. One end of the mounting plate 9 is fixedly connected to the other end of the extension plate 8. Both ends of the driven shaft 10 are rotatably connected to the side walls of the two mounting plates 9 respectively. The driven roller 11 is mounted on the driven shaft 10 and is connected to the driven shaft 11. 0. Coaxial fixed connection, the first mesh belt 12 is tensioned and sleeved on the drive roller 6 and the driven roller 11. The first mesh belt 12 is made of elastic material with strong extensibility. The edge of the mounting plate 9 is set as arc. The mounting plate 9, the extension plate 8 and the connecting plate 7 are all "surrounded" by the tensioned mesh belt and do not contact the mesh belt. The top of the first mesh belt 12 is higher than the inner bottom wall of the feed port 2, and the width of the first mesh belt 12 is smaller than the width of the feed port 2. This facilitates the material to be conveyed into the annealing furnace body 1. By starting the first motor 4, the output end of the first motor 4 rotates and drives the drive shaft 5 to rotate. The drive shaft 5 drives the drive roller 6 to rotate. The drive roller 6 drives the first mesh belt 12 to be transmitted under the support of the drive roller 6 and the driven roller 11. The connecting plate 7, the extension plate 8 and the mounting plate 9 support the driven shaft 10 when it is in the "inside" of the tensioned state of the first mesh belt 12. The auxiliary anti-deviation component is set on the mounting plate 9 to support and drive the two ends of the first mesh belt 12 to tilt up.
[0025] like Figure 1 and Figure 3 As shown, the anti-deviation assembly includes a fixed base 13, a second motor 14, a rotating rod 15, a rotating shaft 17, and a support roller 18. One end of the fixed base 13 is fixedly connected to the outer wall of the mounting plate 9. The second motor 14 is mounted on the outer wall of the fixed base 13. The fixed base 13 has a rotating groove 16 that mates with the rotating rod 15. One end of the rotating rod 15 is located in the rotating groove 16 and slides within it. The rotating groove 16 is arc-shaped and mates with the movement trajectory of the rotating rod 15. The rotating shaft 17 passes through one end of the rotating rod 15 and is fixedly connected to it. Both ends of the rotating shaft 17 are rotatably connected to the two inner walls of the rotating groove 16. The output end of the second motor 14 is fixedly connected to one end of the rotating shaft 17, and the axis of the output end of the second motor 14 coincides with the quarter point of the outer wall of the rotating shaft 17. The second motor 14 is a forward and reverse rotating motor. When the second motor 14 stops rotating... Afterwards, the braking state can be maintained to prevent the pressure of the material on the first mesh belt 12 from causing the rotating shaft 17 to rotate. The support roller 18 is sleeved on the rotating rod 15 and is coaxially connected to the rotating rod 15. The driven roller 11 is located at the center of the first mesh belt 12. The distance between the outer end faces of the two support rollers 18 is greater than the width of the first mesh belt 12. By starting the second motor 14, the output end of the second motor 14 rotates and drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the rotating rod 15 to rotate along the inner wall of the rotating groove 16 with the axis of the rotating shaft 17 as the center. The rotating rod 15 drives the support roller 18 to rotate. The rotation of the support roller 18 causes the two ends of the first mesh belt 12 to tilt up, so that the end face of the first mesh belt 12 is arc-shaped. This can gather the material towards the middle of the first mesh belt 12 and prevent the material from accumulating at one end of the first mesh belt 12, causing the first mesh belt 12 to shift in the direction of material accumulation.
[0026] The material pusher is set at the top of the two support frames 3 and is used to push the material from both sides to the middle. The material pusher and the anti-deviation component are located at the two ends of the top of the support frame 3 respectively. The material pusher includes two fixed plates 19, two electric telescopic rods 20 and a pusher plate 21. The bottom ends of the two fixed plates 19 are fixedly connected to the top ends of the two support frames 3 respectively. Two electric telescopic rods 20 are symmetrically installed on the fixed plates 19. One end of each of the two electric telescopic rods 20 is fixedly connected to one end of the pusher plate 21. The bottom end of the pusher plate 21 is attached to the top end of the first mesh belt 12. After the material is piled on the first mesh belt 12, the pusher plate 21 is moved horizontally toward the center of the first mesh belt 12 by starting the electric telescopic rods 20. The bottom ends of the two pusher plates 21 move toward each other along the upper surface of the first mesh belt 12, so that the material scattered and piled on the edge of the first mesh belt 12 is brought together to the middle.
[0027] It should be further explained that the second motor 14 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method and electrical connection method can be debugged and operated by those skilled in the art according to the requirements of its instruction manual, and will not be described in detail here. The second motor 14 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use requirements to facilitate the operation and control of the operator. At the same time, the motor needs to be connected to the forward and reverse circuit before use for forward and reverse operation. As for the forward and reverse operation of the motor, according to the patent disclosed in patent number CN109889124A, the forward and reverse operation of the motor is a well-known technology to those skilled in the art, and the technology is very mature and can be implemented.
[0028] Working principle: After the mesh belt feeding structure of the annealing furnace is applied to the annealing furnace body 1, the furnace body 1 is started and heated. Material can then be fed into the furnace body 1 through this structure. The first motor 4 drives the first mesh belt 12, which is supported by the drive roller 6 and the driven roller 11, to transport the material onto the mesh belt 12. Then, the telescopic rod is activated, causing the pusher plates 21 to move horizontally towards the center of the mesh belt 12. The bottom ends of the two pusher plates 21 move towards each other along the upper surface of the mesh belt 12, thus bringing the scattered material accumulated on the edges of the mesh belt 12 towards the center. The material is then transported along the first mesh belt 12. The material is conveyed by starting the second motor 14. The output end of the second motor 14 rotates, which drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the rotating rod 15 to rotate around the axis of the rotating shaft 17 along the inner wall of the rotating groove 16. The rotating rod 15 drives the support roller 18 to rotate. The rotation of the support roller 18 causes the two ends of the first mesh belt 12 to be raised, so that the end face of the first mesh belt 12 is arc-shaped. This can gather the material towards the middle of the first mesh belt 12 and prevent the material from accumulating at one end of the first mesh belt 12, causing the first mesh belt 12 to deviate in the direction of material accumulation. The material enters the annealing furnace body 1 through the guidance of the two pusher plates 21 and the conveying of the first mesh belt 12, thus preventing the first mesh belt 12 from deviating and causing the material to fall.
