It consists of a shell, a conveying system, a heating system, and a control system, and is widely used in industries such as food processing, electronics, and chemical engineering. Since different products usually require a specific temperature range to achieve the best baking, drying, or curing effects when processed in a tunnel furnace to ensure process consistency, if the temperature in different areas of the tunnel furnace varies greatly, the product may experience local overheating or overcooling when passing through these areas, resulting in defects such as deformation, cracking, and uneven color. Therefore, it is necessary to detect the temperature inside the tunnel furnace. Currently, the tunnel furnace temperature detection device is often directly placed on the ground, and the temperature is detected by putting the detection probe connected by a wire harness into the tunnel furnace. The user needs to bend down to adjust and control the temperature detection device, and the operation is rather inconvenient. Therefore, a tunnel furnace temperature detection device is needed.

[0003] For the existing tunnel furnace temperature detection device, when in use, it is inconvenient to adjust the height of the temperature detection device, resulting in inconvenient use, and it can only obtain the temperature data at a fixed height inside the tunnel furnace, and cannot understand the temperature conditions in other height areas, and it is also inconvenient to clamp and store the detection probe.

A movable block 5 is movably connected to the outer wall of the threaded rod 4. A threaded groove 6 is opened inside the movable block 5. A receiving plate 7 is fixedly connected to one side of the movable block 5. A temperature detector 8 is fixedly connected to the outer wall of the receiving plate 7. A warning lamp 9 is installed on the top of the temperature detector 8. A connecting wire 10 is installed at the bottom of the temperature detector 8. One end of the connecting wire 10 is fixedly connected to a temperature detection probe 11. The threaded rod 4 and the housing 2 form a rotating structure, and the threaded rod 4 is threadedly connected to the movable block 5 through the threaded groove 6. The housing 2 is of a slotted design, and the housing 2 and the movable block 5 form a sliding structure. The receiving plate 7 is arranged symmetrically with respect to the central axis of the movable block 5, and the temperature detector 8 is arranged parallel to the base 1, which can facilitate the adjustment of the height of the temperature detector 8 and improve the convenience of the temperature detection operation in the tunnel furnace.

[0023] Please refer to Figures 1-4 A tunnel furnace temperature detection device. A side plate 12 is fixedly connected to one side of the housing 2. A movable rod 13 is movably connected inside the side plate 12. One end of the movable rod 13 is fixedly connected to a clamping plate 14.

[0024] Working principle: When in use, by starting the driving motor 3, the threaded rod 4 can be rotated. Since the threaded rod 4 is threadedly connected to the movable block 5, the movable block 5 can slide up and down along the outer shell 2, thereby driving the temperature detector 8 fixedly connected to the outer wall of the receiving plate 7 to move up and down. When the temperature detector 8 rises to an appropriate height, the temperature detection probe 11 fixedly connected to one end of the connecting wire 10 is placed in the tunnel furnace, and the furnace temperature can be detected.

The temperature detection probe 11 is placed between the two clamping plates 14, and the clamping plates 14 are released. Under the action of the spring, the clamping plates 14 clamp and store the temperature detection probe 11. In this way, the use process of the device is completed.
