It is difficult to meet the requirements of temperature control accuracy and production flexibility in fields such as electronic component welding, low-temperature food baking, and composite material curing. Split-type infrared tunnel furnace devices, with their high efficiency and uniformity of infrared radiation heating, combined with the modular combination advantages of split design, can flexibly adapt to different site and production capacity requirements. They provide efficient and energy-saving heating solutions, especially for small and medium-sized enterprises and sites with limited space, and are gradually becoming key equipment in precision manufacturing and light industrial production.

[0003] Existing technologies rely on manual placement of objects when heating a single object, which makes it difficult to guarantee the accuracy and consistency of the initial placement position. This can easily lead to offset or misalignment, making it difficult to ensure that the object enters the heating area in the center. Consequently, problems such as overheating, underheating, or uneven heating can occur during the heating process, making it difficult to maintain stable heating quality. Utility Model Content

[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 1:

[0028] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a split-type infrared tunnel furnace device, including a base 1, a steel chain conveyor mechanism 2 provided on the inner wall of the base 1, a shell 3 fixedly connected to the upper surface of the base 1, a support frame 5 fixedly connected to the outer wall of the shell 3, a U-shaped block 6 fixedly connected to the outer wall of the support frame 5, a rack 7 slidably connected to the inner wall of the U-shaped block 6, a gear 8 meshing with the tooth end of the rack 7, a rotating rod 9 fixedly connected inside the gear 8, the outer wall of the rotating rod 9 rotatably connected to the inside of the base 1, a connecting block 10 fixedly connected to the outer wall of the rotating rod 9, a material distribution plate 11 fixedly connected to the outer wall of the connecting block 10, a connecting block 2 15 fixedly connected to the outer wall of the rack 7, and a rotating assembly provided on the inner wall of the support frame 5.

[0029] Specifically, the base 1 provides support, the steel chain conveyor 2 carries the heated object and transports it, and the outer shell 3 is fixed to the upper surface of the base 1 to provide a relatively enclosed space for heating, reducing heat loss. It also supports the support frame 5. The U-shaped block 6 limits the rack 7, ensuring that the U-shaped block 6 always moves horizontally in a straight line during movement. The movement of the rack 7 causes the gear 8 to rotate, converting linear movement into rotational motion. This causes the rotating rod 9 to rotate through the connecting block 10. The rotation of the dividing plate 11 creates an angle tilt, achieving centered transport of a single object.

[0030] Reference Figure 3 The rotating component includes a motor 12, the outer wall of which is fixedly connected to the inner wall of the support frame 5. The output end of the motor 12 is rotatably connected to the inside of the connecting block 15 and is fixedly connected to a rotating block 13. The outer wall of the rotating block 13 is rotatably connected to a connecting rod 14, and the outer wall of the connecting rod 14 is rotatably connected to the outer wall of the connecting block 15.

[0031] Specifically, the rotating component causes the rack 7 to move inward simultaneously, which in turn causes the gear 8 to rotate. When the motor 12 starts, the output end of the motor 12 rotates and drives the rotating block 13 to rotate. During the rotation of the rotating block 13, the connecting rod 14 will rotate on the outer wall of the rotating block 13 and the connecting block 15 and pull the connecting block 15 to move inward. The inward movement of the connecting block 15 drives the rack 7 to move inward.

[0032] Reference Figure 2 The inner wall of the outer shell 3 has a ceramic infrared heating plate 4.

[0033] Specifically, the ceramic infrared heating plate 4 can convert electrical energy into infrared radiation energy, which acts directly on the surface and interior of the object, generating heat through molecular vibration to achieve rapid and efficient heating.

[0034] Reference Figure 4 A U-shaped frame 17 is fixedly connected to the upper surface of the base 1, and the outer wall of the rotating rod 9 is rotatably connected to the inside of the U-shaped frame 17.

[0035] Specifically, the U-shaped frame 17, which is fixedly connected to the upper surface of the base 1, provides support for the rotation of the rotating rod 9, ensuring that the rotating rod 9 remains stable during rotation.

[0036] Example 2:

[0037] Reference Figure 4 and Figure 5 A connecting strip 159 is fixedly connected to the outer wall of the outer casing 3. A rectangular frame 151 is fixedly connected to the outer wall of the connecting strip 159. A slide rail 152 is fixedly connected to the outer wall of the rectangular frame 151. A movable plate 154 is slidably connected to the outer wall of the slide rail 152. A sloping groove 155 is opened on the outer wall of the movable plate 154. A slide rod 156 is fixedly connected to the inner wall of the rectangular frame 151. A partition plate 158 is slidably connected to the outer wall of the slide rod 156. A sliding column 157 is fixedly connected to the outer wall of the partition plate 158. The outer wall of the sliding column 157 is slidably connected to the inner wall of the sloping groove 155. An electric push rod 153 is fixedly connected to the upper surface of the rectangular frame 151. The output end of the electric push rod 153 is slidably connected to the inside of the rectangular frame 151 and fixedly connected to the upper surface of the movable plate 154. There are two slide rails 152, which are symmetrically arranged on the two outer walls of the rectangular frame 151.

[0038] Specifically, when multiple identical objects are placed directly on the outer casing 3 for heating, the electric push rod 153 can be activated. Activation of the electric push rod 153 causes its output end to slide inside the rectangular frame 151 and causes the moving plate 154 to move downwards. During the downward movement of the moving plate 154, the sliding column 157 is passively slid against the inner wall of the inclined groove 155 opened on the outer wall of the moving plate 154. As the sliding column 157 slides against the inner wall of the inclined groove 155, it moves outwards. This outward movement of the sliding column 157 causes the partition plate 158 to move outwards and slide against the outer wall of the sliding rod 156. The partition plate 158 can physically separate the objects about to enter the heating area, ensuring that each object has its own independent space, reducing mutual interference. At the same time, the spacing of the partition plate 158 can be flexibly changed according to the size and specifications of different objects to adapt to the size of the objects.

[0039] Example 3:

[0040] Reference Figure 6 In this embodiment, another structure is provided compared to the first embodiment above: a fixing plate 161 is fixedly connected to the upper surface of the base 1, an electric push rod 162 is fixedly connected to the outer wall of the fixing plate 161, a clamping plate 163 is fixedly connected to the output end of the electric push rod 162, a limit rod 164 is fixedly connected to the outer wall of the clamping plate 163, and the outer wall of the limit rod 164 is slidably connected to the inside of the fixing plate 161; there are two fixing plates 161, which are symmetrically arranged on both sides of the base 1.

[0041] Specifically, when it is necessary to heat the objects on the tray, after the tray is placed on the steel chain conveyor mechanism 2 and before entering the interior of the outer casing 3, the electric push rod 162 is activated. The activation of the electric push rod 162 causes its output end to slide inside the fixed plate 161 and drive the clamping plate 163 to move inward. During the inward movement of the clamping plate 163, the limiting rod 164 moves inward and slides inside the fixed plate 161. By moving the clamping plate 163 inward, the objects on the tray can be kept in a centered position, which can ensure that all parts of the objects receive infrared radiation evenly and avoid local overheating or underheating due to positional deviation, thereby ensuring the stability of heating quality. The centered position can reduce the possibility of collision and friction between the objects and other parts, reducing the risk of damage to the objects.

[0042] Working principle: When a single object needs to be heated, motor 12 is started. The start of motor 12 causes rotating block 2 13 to rotate. The rotation of rotating block 2 13 causes connecting rod 14 to rotate simultaneously on the outer wall of rotating block 2 13 and connecting block 2 15, and pulls rack 7 to move inward and slide on the inner wall of U-shaped block 6. The movement of rack 7 causes gear 8 to rotate. During the rotation of gear 8, rotating rod 9 rotates inside base 1 and drives connecting block 1 10 to rotate. During the rotation of connecting block 1 10, distributing plate 11 rotates. The rotation of distributing plate 11 creates an angle tilt, which can guide the initial placement of the single object, correct the offset, and ensure that the object enters the heating area in a centered position, preventing overheating, underheating, or uneven heating, and ensuring stable heating quality.

[0043] 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.
