[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0028] like Figures 1 to 4 As shown, a multi-layer baking device includes a housing 1 and controllers 2 installed on both sides of the housing 1. The housing 1 has a left baking chamber 3 and a right baking chamber 4 with identical structures spaced apart. The left baking chamber 3 is equipped with a heating device electrically connected to the controller 2. The left baking chamber 3 includes several layers of baking racks 5 arranged from top to bottom. Any two layers of baking racks 5 are connected. This design ensures that the temperature can be evenly distributed on each layer of racks after the heating device is working, ensuring that the materials on each layer of racks can be baked. Each layer of baking rack 5 is equipped with a shelf 6 for placing the materials to be baked. The front end of each layer of baking rack 5 is equipped with a door 7 that is rotatably connected to the housing 1. The door 7 of each layer of baking rack 5 can be opened and closed independently. The top two sides of the housing 1 are respectively equipped with a first fan 9 and a second fan 11 for conveying air to the interior of the left baking chamber 3 and the right baking chamber 4. The first fan 9 is electrically connected to the controller 2 near the left baking chamber 3, and the second fan 11 is electrically connected to the controller 2 near the right baking chamber 4.

[0029] It is understood that the oven body 1 can be equipped with drying chambers of the same structure at intervals. The chambers can be set according to production needs and are not limited to the design of the left drying chamber 3 and the right drying chamber 4 in this embodiment. They need to meet the structural requirements of the left drying chamber 3 or the right drying chamber 4 in this embodiment.

[0030] When the baking device is working, the controller 2 near the left baking chamber 3 starts the first fan 9 to deliver airflow into the left baking chamber 3, so that the temperature in the left baking chamber 3 is evenly distributed on the materials on each layer of baking racks 5 in the left baking chamber 3; similarly, the controller 2 near the right baking chamber 4 starts the second fan 11 to deliver airflow into the right baking chamber 4, so that the temperature in the right baking chamber 4 is evenly distributed on the materials on each layer of baking racks 5 in the right baking chamber 4; when only the left baking chamber 3 or the right baking chamber 4 needs to be used for baking, it is only necessary to start the corresponding controller 2 and the fan electrically connected to the controller 2. In this embodiment, the materials on each layer of baking racks 5 in the left baking chamber 3 and the right baking chamber 4 can be baked at the same time, thereby improving the baking efficiency.

[0031] To enable each shelf door 7 to be opened and closed independently, a concave buckle 13 is fixedly installed on the box body 1, and a connecting buckle 14 that is hinged to the concave buckle 13 is fixedly installed on the movable end of the door 7. The two sides of the connecting buckle 14 are respectively hinged to the two sides of the concave buckle 13 by screws.

[0032] A side plate 15 is fixedly installed on the opening and closing end of the door 7. A support plate 16 is fixedly installed on the side of the box body 1 near the opening and closing end of the door 7. A limit switch electrically connected to the controller 2 is fixedly installed on the support plate 16. The roller 17 of the limit switch can abut against the side plate 15. Specifically, the limit switch includes an operating mechanism fixedly connected to the support plate 16. The output end of the operating mechanism is connected to a rotating shaft. The rotating shaft is connected to a fixed block with a push rod. The end of the push rod is provided with a roller 17. The working principle of the limit switch in cooperation with the door 7 and the controller 2 is as follows:

[0033] When it is necessary to open the door 7 at the front of a certain drying rack 5 in the left drying chamber 3, rotate the push rod to move the roller 17 away from the side plate 15. As the roller 17 moves away from the side plate 15, it will collide with the side plate 15. The controller 2 will interrupt the heating device to heat the drying rack 5. The heat of the drying rack 5 will accumulate downward under the action of the first fan 9, thereby reducing the temperature of the drying rack 5 and making it easier for the operator to remove the material on the drying rack 5.

[0034] Therefore, the design of the independent opening and closing of the door 7 ensures that it will not affect the baking of materials on other drying racks 5.

[0035] Inside the housing 1, a baffle 8 is installed at the top, connecting the left drying chamber 3 and the right drying chamber 4. The baffle 8 has a left limiting hole 10 and a right limiting hole 12 symmetrically opened on both sides. The left limiting hole 10 is configured to cooperate with the air outlet of the first fan 9, and the right limiting hole 12 is configured to cooperate with the air outlet of the second fan 11. The left limiting hole 10 communicates with the inside of the left drying chamber 3, and the right limiting hole 12 communicates with the inside of the right drying chamber 4. This configuration can securely fix the first fan 9 and the second fan 11 in the left drying chamber 3 and the right drying chamber 4, respectively.

[0036] Each drying rack 5 is equipped with a crash barrier 18 between its front end and the corresponding door 7. The shape of the crash barrier 18 is adapted to the drying rack 5, and the crash barrier 18 can ensure that the door 7 will not be damaged when closed.

[0037] The heating device includes a heat-conducting plate 19 disposed on one side of the left drying chamber 3 and a heat dissipation plate 20 disposed on the sides of several drying racks 5. The heat dissipation plate 20 is provided with several heat dissipation holes 21. A heating tube 22 connected to the top of the box body 1 is installed between the heat-conducting plate 19 and the heat dissipation plate 20. The heating device can heat the material on the drying racks 5. In order to improve the baking efficiency of the material on each drying rack 5, the above-mentioned heating device is provided on both sides of the left drying chamber 3. Similarly, the above-mentioned heating device is also provided on both sides of the right drying chamber 4.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
