Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a chain roller conveyor structure for a heat treatment equipment. Background Technology

[0002] In the heat treatment industry, chain roller conveyor structures are a key component of heat treatment equipment, primarily responsible for the stable transfer of workpieces between different processing stations. However, the chain roller conveyor structures used in most heat treatment equipment on the market currently have significant drawbacks.

[0003] In existing chain roller conveyor structures, the chains are typically exposed without effective protective measures. During the transport of heat-treated workpieces, foreign objects such as iron filings and debris generated during processing may remain on the workpiece surface. These foreign objects easily detach and adhere to the chain surface during transport. Simultaneously, the heat treatment workshop environment is generally characterized by a large amount of dust, which continuously settles onto the chain. Once foreign objects and dust enter critical parts of the chain, such as chain links and sprocket meshing, they disrupt the chain's original lubrication, increasing chain running resistance, accelerating wear between the chain and sprockets, and reducing the chain's service life. In severe cases, it can even cause the chain to jam, seize, or break, leading to a malfunction and shutdown of the entire conveyor system. This affects the continuous and stable operation of the heat treatment equipment, increases equipment maintenance costs and production downtime, and reduces production efficiency. Therefore, we propose a chain roller conveyor structure for heat treatment equipment to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a chain roller conveyor structure for heat treatment equipment, mainly to solve the problem that in existing technologies, foreign objects such as iron filings and debris generated during processing may remain on the workpiece surface. These foreign objects easily detach and adhere to the chain surface during conveying. Simultaneously, a large amount of dust is commonly present in the heat treatment workshop environment, and this dust continuously settles onto the chain. Once foreign objects and dust enter key parts of the chain, such as chain links and sprocket meshing, they will disrupt the original lubrication of the chain, leading to increased chain running resistance, accelerated wear between the chain and sprocket, and reduced chain lifespan. In severe cases, it may even cause the chain to jam, seize, or even break, resulting in the entire conveyor system malfunctioning and shutting down, affecting the continuous and stable operation of the heat treatment equipment, increasing equipment maintenance costs and production downtime, and reducing production efficiency. The following technical solution is provided, which will be discussed in conjunction with… Figures 1-4 Please provide a detailed explanation:

[0027] A chain roller conveyor structure for a heat treatment equipment, comprising:

[0028] Mounting frame 1, mounting rods 2 are rotatably connected at equal intervals between the inner sidewalls of mounting frame 1, and support wheels 201 are fixed on both sides of mounting rods 2;

[0029] Mounting box 3 is fixed to one side of mounting frame 1, and one end of mounting rod 2 extends into the interior of mounting box 3. The front and top surfaces of mounting box 3 are open structures.

[0030] Installation cabinet 4 is connected to the bottom of installation box 3, and a cabinet door 401 is hinged to one side of the front of installation cabinet 4;

[0031] The drive chain assembly 5 is located inside the mounting cabinet 4. The drive chain assembly 5 is used to drive one of the mounting rods 2 to rotate. The drive chain assembly 5 includes a drive motor 501 mounted on the bottom side of the back of the mounting cabinet 4. The output shaft of the drive motor 501 is connected to a drive sprocket 502. A driven sprocket 503 is fixed at the end of one of the mounting rods 2. A drive chain 504 is connected between the drive sprocket 502 and the driven sprocket 503.

[0032] The linkage chain assembly 6 is located inside the mounting box 3. The linkage chain assembly 6 is used to drive other mounting rods 2 to rotate. The linkage chain assembly 6 includes a linkage sprocket 601 fixed to the end side of the mounting rod 2, and a transmission chain 602 is connected between two adjacent linkage sprockets 601.

[0033] Dustproof components 7 are disposed on the front and top surfaces of the mounting box 3. Dustproof components 7 are used to prevent dust and debris from entering the interior of the mounting box 3. Dustproof components 7 include first hollow plates 701 fixed at equal intervals on the top surface of the mounting box 3. A first baffle 702 is slidably inserted through one end of the first hollow plate 701. A second hollow plate 703 is fixed at the intervals of the first hollow plates 701 on the front surface of the mounting box 3. A second baffle 704 is slidably inserted through one end of the second hollow plate 703.

[0034] Workflow Description

[0035] Workpiece support and conveying preparation:

[0036] The workpiece to be processed is placed on the support wheel 201 in preparation for subsequent conveying.

[0037] Transportation process:

[0038] The drive motor 501, installed on the bottom back of the mounting cabinet 4, is turned on. The output shaft of the drive motor 501 drives the drive sprocket 502 to rotate. The drive sprocket 502 is connected to the driven sprocket 503 at the end of one of the mounting rods 2 via a drive chain 504, thereby driving the mounting rod 2 to rotate. As the mounting rod 2 connected to the drive motor 501 rotates, the linkage chain assembly also starts to rotate. Adjacent linkage sprockets 601 are connected via a transmission chain 602. The rotation of such a linkage sprocket 601 will drive the adjacent linkage sprockets 601 and the mounting rod 2 connected to them to rotate. In this way, multiple mounting rods 2 rotate in coordination under the action of the linkage chain assembly 6, realizing the synchronous rotation of the support wheel 201, thereby pushing the workpiece placed on the support wheel 201 to move along the length of the mounting frame 1, completing the workpiece conveying process in the heat treatment equipment.

[0039] Dustproof component 7 operation:

[0040] During the operation of the conveyor structure, the dustproof component 7 plays an important role. The first baffle 702, which slides through the first hollow plate 701 on the top surface of the mounting box 3, and the second baffle 704, which slides through the second hollow plate 703 on the front surface, work together to prevent dust and debris from entering the interior of the mounting box 3. When maintenance is required on the linkage chain component 6 and other components inside the mounting box 3, the staff can push the first baffle 702 and the second baffle 704 into the interior of the first hollow plate 701 and the second hollow plate, respectively, which facilitates the maintenance operation. After the maintenance is completed, the baffles are pushed back to their original positions to restore the dustproof function.

[0041] Unlike existing technologies where the chain roller conveyor structure of this heat treatment equipment exposes the chain, this device conceals the drive chain assembly 5 inside the mounting cabinet 4 and the linkage chain assembly 6 inside the mounting box 3. This design reduces the chain's contact with the external environment, effectively preventing the impact of residual iron filings, debris, and workshop dust on critical parts of the chain. It fundamentally solves the problem of chain wear, jamming, and even breakage caused by foreign objects and dust. Furthermore, the dustproof assembly 7 adopts a staggered drawer-like design, specifically a combination of the first hollow plate 701 and the first baffle 702, and the second hollow plate 703 and the second baffle 704. This design provides excellent dust protection during normal operation and allows for quick opening and closing during maintenance. Compared to traditional integrated protective structures, it significantly improves maintenance convenience without compromising dustproof performance.

[0042] like Figure 1As shown, in some embodiments, a first L-shaped plate 705 is fixed to one end of the first baffle 702 located outside the first hollow plate 701, and a second L-shaped plate 706 is fixed to one end of the second baffle 704 located outside the second hollow plate 703. The surfaces of the first L-shaped plate 705 and the second L-shaped plate 706 are both constructed with lifting holes. More specifically, when the first baffle 702 and the second baffle 704 are inserted into the corresponding ports of the first hollow plate 701 and the second hollow plate 703, the first L-shaped plate and the second L-shaped plate will fit tightly against the surface of the mounting box 3. The right-angled structure of the L-shaped plate allows it to fill any gaps that may exist between the baffle and the surface of the mounting box 3, greatly reducing the channels for dust and debris to enter the interior of the mounting box 3. In addition, the lifting holes constructed on the surfaces of the first and second L-shaped plates provide clear and convenient leverage points for workers. When it is necessary to remove the baffle to maintain the interior of the mounting box 3, workers can easily insert their fingers or tools through the lifting holes, apply pulling force, and push the first baffle 702 and the second baffle 704.

[0043] like Figure 1 As shown, in some embodiments, tempered glass 8 is also included, which is detachably mounted on the top of the mounting box 3 near the mounting frame 1. More specifically, the tempered glass, with its robust material and complete surface, forms a solid physical barrier on the top of the mounting box 3. In the complex environment of the heat treatment workshop, foreign objects such as falling dust and flying iron filings will be blocked by the surface of the tempered glass 8 after contacting it, and will not be able to directly enter the interior of the mounting box 3.

[0044] like Figure 2 As shown, in some embodiments, a slot 9 is fixedly provided on the top of the mounting box 3, and the tempered glass 8 is slidably embedded in the inside of the slot 9 on the bottom side. Locking bolts 10 are threadedly connected to both sides of the front of the slot 9. More specifically, when the locking bolts 10 are tightened, the bolt screws apply pressure to the side of the tempered glass 8, which increases the pressure between the tempered glass 8 and the inner wall of the slot 9. When it is necessary to disassemble the tempered glass 8 for maintenance or cleaning, use a wrench to turn the locking bolts 10 on both sides of the front of the slot 9 in the opposite direction to unscrew the bolts from the threaded holes. After the bolts are completely unscrewed, hold both sides of the tempered glass 8, gently lift it up and pull it out along the direction of the slot 9 to remove the tempered glass 8 from the top of the mounting box 3.
