Mounting rod 4, a damping rod 5 is fixedly mounted on the surface of the hollow mounting rod 4, a mounting plate 6 is fixedly mounted on the top of the damping rod 5, a cleaning brush 7 that contacts the surface of the conveyor belt 2 is fixedly mounted on the upper surface of the mounting plate 6, a rectangular hollow plate 8 is fixedly mounted on the inner side of the rectangular frame 3, a first top spring 9 is fixedly mounted inside the rectangular hollow plate 8, a connecting plate 10 is slidably mounted on one end of the first top spring 9, a scraper 11 that extends to the outside of the rectangular hollow plate 8 and contacts the surface of the conveyor belt 2 is fixedly mounted on the surface of the connecting plate 10, the rectangular hollow plate 8 and the scraper 11 are both inclined inside the rectangular frame 3, so that the scraper 11 can better contact the surface of the conveyor belt 2 to scrape off the residue on the surface of the conveyor belt 2.

[0030] A rectangular hole 12 is provided on one side surface of the rectangular frame 3. A support strip 13 is fixedly installed on the opposite side surface inside the rectangular frame 3. A collection box 14 that contacts the support strip 13 is inserted into the rectangular hole 12 to facilitate the collection of the cleaned residue.

[0031] The hollow mounting rod 4 is rectangular in shape. A partition 15 is fixedly installed inside the hollow mounting rod 4. A second top spring 16 is fixedly installed on the opposite surface of the partition 15. A rectangular connecting block 17 is fixedly installed at one end of the second top spring 16. An extension rod 18 extending to the outside of the hollow mounting rod 4 is fixedly installed at one end of the rectangular connecting block 17. A locking block 19 is fixedly installed at one end of the extension rod 18. A slot 20 matching the locking block 19 is formed on the opposite surface inside the rectangular frame 3, allowing for a snap-fit ​​connection.

[0032] It should be noted that the tunnel oven body 1 in this embodiment is a temperature-controlled tunnel oven for bread processing. The working principle of this tunnel oven is mainly based on heat conduction, convection and radiation to bake bread. Through the intelligent control system, the oven temperature can be precisely adjusted to ensure the efficiency and stability of the baking process. The intelligent control system can precisely adjust the temperature of the heating element according to different bread baking needs. Whether it is the dough fermentation stage or the baking stage, the temperature can be controlled just right. The temperature sensor built into the system will monitor the oven temperature in real time to ensure that the temperature is always kept within the set range. The intelligent control system can pre-store multiple sets of baking parameters, which can facilitate users to quickly switch according to different bread types and baking needs.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, press the extension rod 18 into the hollow mounting rod 4, compressing the second top spring 16, aligning the locking block 19 with the locking slot 20, and then release the extension rod 18. The second top spring 16 pushes the extension rod 18 out, causing the locking block 19 to engage with the locking slot 20, thus completing the installation of the hollow mounting rod 4. The cooperation between the hollow mounting rod 4 and the rectangular connecting block 17 can limit the extension rod 18, preventing rotation of the hollow mounting rod 4 and the extension rod 18. At this time, the damping rod 5 pushes the mounting plate 6 and the cleaning brush 7 upward, causing the cleaning brush 7 to contact the surface of the conveyor belt 2. The first top spring 9 pushes the connecting plate 10 and the scraper 11, so that the scraper 11 comes into contact with the surface of the conveyor belt 2. When the conveyor belt 2 is running, the scraper 11 will scrape off the residue on the surface of the conveyor belt 2. By using the frictional contact between the cleaning brush 7 and the surface of the conveyor belt 2, the surface of the conveyor belt 2 can be cleaned a second time, thereby improving the cleaning effect on the surface of the conveyor belt 2. When the cleaning brush 7 needs to be replaced, simply pull the locking rod 23 out of the locking hole 21 and then insert the locking rod 23 on the new cleaning brush 7 into the locking hole 21, so that the rubber retaining ring 22 fits into the annular groove 24.
