Description

Technical Field

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

[0002] Mesh belt furnaces are commonly used in metal heat treatment processes. They heat components within a furnace chamber that moves along a mesh belt, under set temperatures and atmospheres, to meet the requirements of processes such as annealing, quenching, and sintering. Due to the use of mesh belt transport, components can be continuously conveyed and processed in batches, making them widely used in machinery manufacturing, powder metallurgy, and hardware processing.

[0003] However, conveyor belts are typically formed by woven or welded metal wires, resulting in gaps on their surface. When the heated components are small or have small protrusions, they can easily get stuck in these gaps. Once stuck, components cannot be smoothly conveyed or properly discharged, affecting not only the processing quality but also potentially causing conveyor blockages, disrupting production rhythm, and even leading to equipment downtime for maintenance, thus reducing production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem mentioned in the background art that small parts are easily stuck in the gaps of the mesh belt, and to propose an auxiliary device for conveying a mesh belt heating furnace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An auxiliary device for conveying a mesh belt heating furnace includes an outer casing, in which a mesh plate capable of vertical movement is placed. The mesh plate has uniformly distributed mesh holes. The outer casing has a storage groove above the mesh plate and a flow hole below the mesh plate that communicates with the mesh holes. An ejector assembly is provided between the mesh plate and the outer casing, and the ejector assembly can clear the mesh holes.

[0007] The outer casing includes a surrounding panel and a bottom plate. A top rod corresponding to each mesh hole is fixedly connected to the bottom plate. Moving the mesh panel allows the top rod to pass through or move away from the mesh hole.

[0008] The bottom plate has the aforementioned flow holes.

[0009] The flow holes are provided in the portion of the enclosure below the mesh panel.

[0010] Several top posts are fixed to the bottom of the mesh plate, and the top posts penetrate the bottom plate.

[0011] The base plate is fixed with support feet at its four corners.

[0012] The mesh has a deep hole structure with a hole depth greater than millimeters.

[0013] The mesh plate includes two plates spaced apart vertically. The plates have evenly distributed through holes. A tube corresponding to each through hole is fixed between the two plates. The through holes and the internal space of the tubes form the mesh.

[0014] The outer casing is fixed to a handle or lifting ring on its outer wall.

[0015] The present invention provides an auxiliary conveying device for a mesh belt heating furnace, which has the following advantages: By installing a vertically movable mesh plate inside the outer casing, and forming mesh holes and connecting flow holes on the mesh plate, sufficient flow of hot air is ensured during the heating process, improving heating uniformity. Simultaneously, the ejector assembly can eject the protruding parts inserted into the mesh holes after the components have been heated, ensuring that the top surface of the mesh plate remains flat, thereby preventing components from jamming and improving the stability of the mesh belt heating furnace.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-9 An auxiliary device for conveying a mesh belt heating furnace includes an outer casing 1, inside which a mesh plate 2 that can move up and down is placed, the mesh plate 2 having uniformly distributed mesh holes 3, the outer casing 1 having a storage groove 4 above the mesh plate 2, the outer casing 1 having a flow hole 6 below the mesh plate 2 that can communicate with the mesh holes 3, and an ejector assembly between the mesh plate 2 and the outer casing 1, the ejector assembly being able to clear the mesh holes 3.

[0029] In use, the outer casing 1 is placed on the mesh belt of the mesh belt heating furnace. The parts to be heated are placed in the storage tank 4 and enter the furnace chamber for heating as the furnace operates. The mesh plate 2 inside the outer casing 1 can move up and down. Mesh holes 3 are evenly distributed on the mesh plate 2. A flow hole 6 communicating with the mesh holes 3 is located at the bottom of the outer casing 1. Hot air in the furnace chamber can circulate up and down through the mesh holes 3 and the flow hole 6, thus preventing uneven heating of the parts. After heating is complete, the operator removes the outer casing 1 from the furnace. Since some protruding parts of the parts may be inserted into the mesh holes 3, the ejector assembly between the mesh plate 2 and the outer casing 1 pushes out the parts inserted into the mesh holes 3, restoring the top surface of the mesh plate 2 to a flat surface, facilitating the smooth removal of the parts as a whole. The auxiliary device prevents parts from getting stuck on the mesh belt, and the auxiliary device itself also prevents parts from getting stuck.

[0030] By installing a vertically movable mesh plate 2 inside the outer casing 1, and forming mesh holes 3 and connecting flow holes 6 on the mesh plate 2, sufficient flow of hot air is ensured during the heating process, improving heating uniformity. At the same time, the ejector assembly can eject the protruding parts inserted into the mesh holes 3 after the parts are heated, ensuring that the top surface of the mesh plate 2 remains flat, thereby avoiding parts jamming and improving the stability of the mesh belt heating furnace.

[0031] In one embodiment, the outer casing 1 includes a surrounding panel 9 and a bottom plate 13. A top rod 14, corresponding one-to-one with the mesh openings 3, is fixedly connected to the bottom plate 13. The movable mesh plate 2 allows the top rods 14 to pass through or move away from the mesh openings 3. (Reference) Figure 8 By moving the upper and lower mesh plates 2, the push rod 14 passes through the mesh holes 3, pushing out the inserted parts.

[0032] The base plate 13 has flow holes 6; the surrounding plate 9 has flow holes 6 at the part below the mesh plate 2. The flow holes facilitate the passage of hot air through the components.

[0033] Several top posts 8 are fixed to the bottom of the mesh panel 2, and the top posts 8 penetrate the bottom plate 13; (Reference) Figure 7 When the device is placed on the conveyor belt, it is supported by the top column 8. Under the action of gravity, the outer casing 1 falls downwards. Finally, the outer casing 1 is supported on the conveyor belt by the support feet 7 at the four corners of the base plate 13. In this way, the mesh plate 2 is suspended inside the outer casing 1, ensuring that the mesh holes 3 are in a through-hole state. After heating is completed, refer to... Figure 8 By lifting the outer casing 1 upwards, the mesh plate 2 slides downwards relative to the outer casing 1 under the action of gravity, causing the top rod 14 to pass through the mesh hole 3 and push the parts inside the mesh hole 3 upwards, so that the top surface of the mesh plate 2 forms a flat surface without holes, making it easier to remove the parts.

[0034] As a specific working embodiment, this device can be used to temper quenched bolts, nails and other parts.

[0035] As one implementation, the mesh 3 has a deep hole structure with a depth greater than 10 mm. The use of a deep hole structure in the mesh 3 ensures that even if a part partially falls into the mesh, it will not penetrate the mesh. This ensures that when the push rod 14 is inserted upwards into the mesh 3, the part can be retracted from the mesh. (Refer to...) Figure 10 If a very shallow mesh 3 is used for tempering bolts, the bolt thread will completely penetrate the mesh. In this case, the bolt will hinder the upward movement of the push rod 14, making it difficult for the push rod to push the bolt out of the mesh.

[0036] As one implementation method, refer to Figures 2-6 The mesh panel 2 includes two plates 11 spaced apart vertically. Each plate 11 has evenly distributed through holes 10. A tube 12, corresponding to each through hole 10, is fixedly connected between the two plates 11. The through holes 10 and the internal space of the tubes 12 form a mesh 3. Compared to using a very thick mesh panel to form a deeper mesh, this method of forming a deeper mesh 3 not only saves materials and reduces costs but also makes the overall structure lighter.

[0037] The outer wall of the outer casing 1 is fixed with a handle 5 or a lifting ring, which makes it easy to lift the outer casing upwards, move downwards using the gravity mesh 3, and insert the top rod 14 into the mesh.

[0038] As a working method, the outer casing 1 is placed on the mesh belt of the mesh belt heating furnace. The bottom of the outer casing 1 is equipped with support feet 7, which provide stable support to the mesh belt, ensuring the outer casing 1 remains stable under gravity. At this time, the mesh plate 2 inside the outer casing 1 is suspended from the interior of the outer casing 1 by the top column 8, with the mesh holes 3 in a through-hole state; the components to be heated are placed in the storage slot 4 above the outer casing 1. As the mesh belt moves, the outer casing 1, along with the components, enters the furnace chamber; the mesh plate 2 inside the outer casing 1 has evenly distributed mesh holes 3, and the bottom plate 13 and surrounding plate 9 below the outer casing 1 have flow holes 6 communicating with the mesh holes 3. The hot airflow inside the furnace can flow vertically through the mesh 3 and the flow holes 6, achieving uniform heat transfer around the parts, thereby avoiding local overheating or uneven heating of the parts; after heating is completed, the operator can remove the entire outer box 1 from the furnace through the handle 5 or lifting ring fixed on the outer wall of the outer box 1; during the heating process, the protruding parts of the parts may insert into the mesh 3, causing the parts to get stuck inside the outer box. At this time, as the outer casing 1 is lifted, gravity causes the mesh plate 2 to slide downward relative to the outer casing 1. The push rod 14 in the ejection assembly then passes through the mesh hole 3, pushing out the parts stuck in the mesh hole 3, so that the top surface of the mesh plate 2 returns to a flat state. After the action of the ejection assembly, all parts are pushed out onto the plane of the mesh plate 2, and the operator can easily remove them as a whole. The mesh hole 3 is designed as a deep hole structure with a hole depth of more than 10 mm, ensuring that even if parts partially enter the mesh hole, they will not be completely penetrated, thus ensuring that the push rod 14 can effectively push them out. The mesh plate 2 is composed of two plates 11 and a tube 12 to form a deep hole mesh 3, which saves more materials, reduces weight, and lowers manufacturing costs compared to a single thick plate structure.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
