Furthermore, during the heating process, the hot airflow distribution is uneven, making it difficult to ensure uniform heating of the material and affecting the heat treatment quality of the aluminum alloy billets.

[0003] Therefore, this application provides a chain plate mesh belt type aluminum alloy billet heating furnace to meet the requirements. Utility Model Content

[0006] The conveying mechanism includes chain plates and support rods, tracks, sprockets, and a fine-tuning mechanism. An auxiliary frame is provided at the end of the base frame. A first transmission rod and a second transmission rod are rotatably connected to the front and rear auxiliary frames, respectively. Multiple sets of sprockets are mounted on both the first and second transmission rods. The symmetrical sprockets are connected by chain plates, and track wheels are provided on the bottom surface of the chain plates. Multiple sets of support rods are provided on the top surface of the base frame, and U-shaped tracks are provided on the top surface of the support rods. Track wheels are slidably connected in the tracks.

[0007] One of the auxiliary frames is equipped with a fine-tuning mechanism for adjusting the position of the first transmission rod;

[0009] Heating mechanisms are provided on both sides of the partition assembly.

[0010] Preferably, the fine-tuning mechanism includes an adjusting electric push cylinder and a sliding seat.

The fan motor and rotating rod in the circulation mechanism are designed separately and connected by a transmission wheel and transmission belt. When one component fails, it can be disassembled and repaired or replaced individually without replacing the entire unit. This greatly reduces the difficulty and cost of equipment maintenance and improves equipment maintenance efficiency. Attached Figure Description

[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: Reference Figure 1-6 The chain-plate mesh belt aluminum alloy billet heating furnace shown includes a base frame 1 and a processing chamber 2. The processing chamber 2 is installed on the top surface of the base frame 1, and the outer wall of the processing chamber 2 is provided with a feed inlet and a discharge outlet. The feed inlet is normally open, and a lifting door that opens up and down is provided at the discharge outlet. In order to facilitate the material to be delivered into the processing chamber 2, a conveying mechanism is provided on the base frame 1, and a separating component and a circulation mechanism are arranged in sequence above the conveying component. Heating mechanisms are provided on both sides of the separating component. When the circulation mechanism is working, the air generated by it passes through the separating component and the heating mechanism, so that the hot airflow is blown out from below the conveying mechanism to heat treat the material located on the conveying mechanism.

[0028] As one embodiment of this invention, the conveying mechanism has an auxiliary frame at the end of the base frame 1. A first transmission rod 19 and a second transmission rod 24 are rotatably connected to the front and rear auxiliary frames, respectively. Multiple sets of sprockets 20 are mounted on both the first transmission rod 19 and the second transmission rod 24. The symmetrical sprockets 20 are connected by a chain plate 16. A track wheel is provided on the bottom surface of the chain plate 16. Multiple sets of support rods 3 are provided on the top surface of the base frame 1. A U-shaped track 4 is provided on the top surface of the support rods 3. The track wheel is slidably connected in the track 4. The purpose of this is to prevent the chain plate 16 from shifting downwards during use due to excessive material weight. The design of the track wheel can reduce the friction of the chain plate 16 during conveying. Multiple sets of holes are provided on the chain plate 16 to allow airflow to pass through.

[0029] One of the auxiliary frames is equipped with a fine-tuning mechanism for adjusting the position of the first transmission rod 19. Since it is heat-treated, the chain plate 16 will experience thermal expansion and contraction during use. In order to ensure the pre-tightening force of the conveying mechanism, when thermal expansion and contraction occur, the fine-tuning mechanism controls the distance between the first transmission rod 19 and the second transmission rod 24 to ensure the pre-tightening force.

[0030] A motor assembly 21 is provided on another set of auxiliary frames. A drive gear 22 is provided on the drive shaft of the motor assembly 21, and a driven gear 23 that meshes with the drive gear 22 is provided on the second transmission rod 24.

[0031] As one implementation method in this embodiment, the fine-tuning mechanism consists of: an adjusting electric push cylinder 17 fixed on an auxiliary frame, a sliding seat 18 slidably connected to the slide rail of the auxiliary frame, an extension end of the adjusting electric push cylinder 17 connected to the sliding seat 18, and a first transmission rod 19 rotatably connected to the sliding seat 18.

[0032] As one embodiment of this example, the partition component, the flow guiding baffle 5, is symmetrically arranged in multiple sets (the flow guiding baffle 5 is divided into two parts: a vertical part and a bent part), and the flow guiding baffle 5 is connected to the inner wall of the processing chamber 2 by a fixed support rod. The above structure strengthens the structural strength of the flow guiding baffle 5 in the processing chamber 2, and the symmetrical flow guiding baffle 5 is connected by a partition plate 6.

[0033] As one implementation method in this embodiment, the bottom surface of the flow guide baffle 5 is lower than the height of the track 4 so that the conveyed hot air can be blown out from below the chain plate 16.

[0034] As one embodiment of this invention, the circulation mechanism includes: a corrugated guide plate 7, with multiple sets of guide plates 7 arranged around the center of each set of partition plates 6 (the purpose of which is to allow the airflow to spread evenly in all directions, so that the material is heated evenly in subsequent operations). A perforation is provided on the top surface of the processing chamber 2, and a connecting chamber 8 is installed in the perforation. An impeller 9 is rotatably connected to the bottom surface of the connecting chamber 8. A set of rotating rods 10 is rotatably connected to the connecting chamber 8, and the bottom end of the rotating rods 10 is connected to the impeller 9. A fan motor 13 is provided on the top surface of the connecting chamber 8. Both the drive shaft of the fan motor 13 and the top end of the rotating rods 10 are provided with transmission wheels 11. The two sets of transmission wheels 11 are connected by a transmission belt 12. Through the above structural design, the fan motor 13 and the rotating rods 10 are designed separately to facilitate subsequent maintenance and reduce maintenance costs in case of damage.

[0035] As one embodiment of this invention, the heating mechanism has multiple sets of interconnected mounting seats 14 on the top surface of the processing chamber 2, and the processing chamber 2 has holes that are adapted to the mounting seats 14. The heating component 15 is inserted into the mounting seat 14.

[0036] The working principle of this utility model is as follows: Material is placed on the top surface of the chain plate 16. Then, the motor assembly 21 is started. The motor assembly 21 meshes with the driven gear 23 via the drive gear 22, thereby driving the second transmission rod 24, which is coaxial with the driven gear 23, to rotate. The second transmission rod 24, through the coaxial sprocket 20 and chain plate 16, drives the first transmission rod 19 to rotate on the sliding seat 18, thus conveying the material on the top surface of the chain plate 16 into the processing chamber 2. To support the chain plate 16, multiple sets of support rods 3 are provided inside the processing chamber 2. A track 4 is provided on the top surface of the support rods 3. The track wheels on the bottom surface of the chain plate 16 slide within the track 4, thereby reducing friction during movement and preventing the chain plate 16 from sinking. After the material enters the processing chamber 2, the lifting door of the discharge port of the processing chamber 2 is closed. Then, the heating component 15 on the mounting base 14 is started to generate temperature. Subsequently, the fan motor 13 is started, and the transmission wheel 11 on the fan motor 13 drives another set of transmission wheels 11 to rotate through the transmission belt 12. This drives the rotating rod 10 to rotate in the connecting chamber 8. The rotating rod 10 drives the impeller 9 at the bottom to rotate, causing air to blow out from between multiple sets of guide plates 7, pass above the partition plate 6, and then downward through the guide baffle 5 and the heating component 15, so that the hot air is discharged from below the track 4 and passes through the holes on the chain plate 16 to heat treat the material. After the above operations are completed, the lifting door is opened to continue conveying the material.
