[0002] Tunnel oven (food processing type) is a tunnel-type mechanical equipment that bakes food through heat conduction, convection and radiation. The furnace body of this type of oven is generally very long, and the baking chamber is a narrow tunnel with a width of generally 80cm to 140cm. Materials are generally transported in the tunnel by a continuously running conveyor belt. This type of oven can produce continuously, has high production efficiency, saves manpower, and has stable baking quality.
[0003] The existing food processing tunnel furnace still has some shortcomings when in use. For example, when heating materials, the materials are usually placed directly on the surface of the conveyor belt. The outer surface of the material is in direct contact with the hot air flow in the tunnel and heats up rapidly, while the surface of the material in contact with the conveyor belt cannot be in direct contact with the hot air flow, and the temperature rises relatively slowly, resulting in incomplete or uneven heating of the material. Therefore, a heating mechanism for a tunnel furnace is proposed. Utility Model Content
[0004] The purpose of the utility model is to solve any one of the problems in the above-mentioned technologies, and thus proposes a heating mechanism of a tunnel furnace, including a fuselage, a plurality of hot air blowers are equidistantly arranged on the top of the fuselage, a duct is connected to the top of the hot air blower, a conveyor belt is arranged inside the fuselage for transporting materials, a plurality of infrared baking lamps are symmetrically arranged on the two side walls of the fuselage above the conveyor belt, a notch is opened on the conveyor belt, a flip assembly is arranged in the notch, and the flip assembly is used to flip the material.
[0005] Furthermore, the flip assembly includes a mounting seat, a gear, a clamp and a rack. The mounting seat is symmetrically provided with rotating shafts on both sides. The mounting seat is rotatably installed in the slot through the rotating shaft. The rack and the gear can engage with each other. The rack is installed inside the fuselage and is located below the infrared baking lamp. The rack is located at the center of the fuselage.
[0006] Furthermore, the interior of the mounting seat is hollow, and sliding grooves are symmetrically provided on the two side walls of the interior, the clamping block is slidably installed in the sliding grooves, and the gear is fixedly installed on the rotating shaft.
[0007] Furthermore, one side of the clamping block is hollow, and two springs are symmetrically provided on the other side, and the other end of the spring is connected to the inner wall of the mounting seat.
[0008] Furthermore, six supporting feet are equidistantly and symmetrically arranged at the bottom of the fuselage, and a control panel is arranged on one side wall of the fuselage.
[0009] Beneficial effect: The utility model is provided with a flipping assembly. When in use, the staff places the material to be processed between the two clamping blocks on the mounting seat, clamps the material on the clamping blocks by the setting of the spring, and transports it to the inside of the fuselage by the conveyor belt for heating. When the mounting seat moves to the rack, the gear on the rotating shaft meshes with the rack and rotates, driving the mounting seat to flip, thereby flipping the material to make it heated more evenly, avoiding the situation where the surface of the material in contact with the conveyor belt cannot directly contact the hot air flow, resulting in incomplete or uneven heating.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.
[0018] Below, the heating mechanism of the tunnel furnace according to the embodiment of the utility model is described with reference to the accompanying drawings. Figures 1 to 4 As shown, the heating mechanism of the tunnel furnace includes a fuselage 1, a plurality of hot air blowers 2 are equidistantly arranged on the top of the fuselage 1, a duct 201 is connected to the top of the hot air blower 2, a conveyor belt 4 is arranged inside the fuselage 1 for transporting materials, a plurality of infrared baking lamps 3 are symmetrically arranged on the two side walls above the conveyor belt 4 inside the fuselage 1, a slot 401 is opened on the conveyor belt 4, a flip assembly is arranged in the slot 401, and the flip assembly is used to flip the material.
[0019] Preferably, the flip assembly includes a mounting base 5, a gear 6, a clamp 7 and a rack 9, wherein the mounting base 5 is symmetrically provided with a rotating shaft 502 on both sides, and the mounting base 5 is rotatably installed in the slot 401 through the rotating shaft 502, and the rack 9 and the gear 6 can mesh with each other, and the rack 9 is installed inside the fuselage 1 and is located below the infrared baking lamp 3, and the rack 9 is located at the center of the fuselage 1.
[0020] In a specific embodiment: when in use, the conveyor belt 4 transports the material in the mounting seat 5 to the inside of the fuselage 1 for heating. When the mounting seat 5 moves to the rack 9 inside the fuselage 1, the gear 6 on the rotating shaft 502 and the rack 9 are engaged and rotated, driving the mounting seat 5 to flip on the conveyor belt 4, thereby flipping the material on the mounting seat 5 to make it heated more evenly, avoiding the surface of the material in contact with the conveyor belt from being unable to directly contact the hot air flow, resulting in incomplete or uneven heating.
[0021] Preferably, the interior of the mounting seat 5 is hollow, and slide grooves 501 are symmetrically provided on the two side walls of the interior. The clamping block 7 is slidably installed in the slide grooves 501, and the gear 6 is fixedly installed on the rotating shaft 502.
[0022] Preferably, one side of the clamping block 7 is hollowed out, and two springs 8 are symmetrically provided on the other side, and the other end of the spring 8 is connected to the inner wall of the mounting seat 5 .
[0023] In a specific embodiment: when loading and unloading materials, the staff places the materials between the two clamping blocks 7 on the mounting seat 5. At this time, the clamping blocks 7 are pushed by the materials to slide in the slide groove 501 and compress the spring 8. When the materials are placed, the elastic force of the spring 8 pushes the clamping blocks 7 to clamp the materials.
[0024] Preferably, six supporting feet 102 are symmetrically and equidistantly provided at the bottom of the fuselage 1, and a control panel 101 is provided on one side wall of the fuselage 1. The supporting feet 102 raise the fuselage 1 too high to prevent it from directly contacting the ground, and the staff can operate the equipment through the control panel 101.
[0025] Working principle: When loading and unloading materials, the staff places the material between the two clamping blocks 7 on the mounting seat 5. At this time, the clamping block 7 is pushed by the material to slide in the slide groove 501 and compress the spring 8. When the material is placed, the elastic force of the spring 8 pushes the clamping block 7 to clamp the material, and then the conveyor belt 4 transports the material in the mounting seat 5 to the inside of the fuselage 1 for heating. When the mounting seat 5 moves to the rack 9 inside the fuselage 1, the gear 6 on the rotating shaft 502 and the rack 9 are engaged and rotated, driving the mounting seat 5 to flip on the conveyor belt 4, thereby flipping the material on the mounting seat 5, making it more evenly heated, and avoiding the situation that the surface of the material in contact with the conveyor belt cannot directly contact the hot air flow, resulting in incomplete or uneven heating.
