[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed on October 27, 2023, with application number: 202311410307.4, and invention name: "A kind of infrared oven", all contents of which are incorporated by reference into this application. Technical Field

[0029] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] As shown in Figures 1 to 3, an embodiment of the present application provides an infrared drying oven, including a box body 1, a planar infrared system 4, a wind field system 5 and a conveying system 6. A drying chamber 2 is provided in the box body 1, and the planar infrared system 4, the wind field system 5 and the conveying system 6 are arranged in the drying chamber 2. The planar infrared system 4 is provided with one or more planar infrared elements 7 or multiple coplanar planar infrared elements 7.

[0031] The wind field system 5 is used to blow air into the drying chamber 2 .

[0032] The conveying system 6 includes a material conveying platform, which has a material conveying surface for carrying materials. The conveying system 6 is used to convey the materials placed on the material conveying surface along a predetermined direction; wherein the planar infrared system 4 is parallel to the material conveying surface or forms a non-zero angle with it.

[0033] In one embodiment, the planar infrared system 4 faces the material conveying surface. The planar infrared system 4 faces the material conveying surface, which allows the emitted infrared light to directly illuminate the material on the material conveying surface, thereby improving the drying effect.

[0034] In one embodiment, the planar infrared element 7 is an infrared plate 8. As shown in FIG3 , all infrared plates 8 of each planar infrared element 7 have the same shape. Planar infrared plates are a common structure that provides good illumination, is easy to design and install, and reduces costs.

[0035] In one embodiment, the infrared plate 8 is rectangular. In other embodiments, the infrared plate 8 may be circular, elliptical, triangular, trapezoidal, parallelogram, or hexagonal.

[0036] In one embodiment, all the infrared plates 8 of each planar infrared element 7 are connected to each other, which can increase the irradiation area of ​​the infrared light of the planar infrared element 7 and improve the lighting effect.

[0037] In one embodiment, the infrared oven further includes a mounting structure, and the mounting structure is used to mount the planar infrared system 4 on the cavity wall of the drying cavity 2 .

[0038] In one embodiment, the wind field system 5 includes a wind box 9 and a wind nozzle 10 . The wind box 9 is installed on the top wall of the drying chamber 2 . The wind nozzle 10 connects the wind box 9 with the drying chamber 2 .

[0039] The mounting structure includes a height adjustment assembly 11 and an angle adjustment assembly 16. The height adjustment assembly 11 is connected to the bellows 9, and the planar infrared system 4 is connected to the angle adjustment assembly 16. The height adjustment assembly 11 is used to adjust the distance between the planar infrared system 4 and the material conveying surface, and the angle adjustment assembly 16 is used to adjust the angle between the planar infrared system 4 and the material conveying surface. The height adjustment assembly 11 can reduce or increase the distance between the planar infrared system 4 and the material, and the angle adjustment assembly 16 can adjust the tilt angle of the planar infrared system 4 so that the planar infrared system 4 can directly face the surface of the material, thereby better irradiating and drying the material.

[0040] In one embodiment, the height adjustment assembly 11 includes a lifting plate 12, a first support shaft 14, and a first nut 15. The first support shaft 14 is connected to the bellows 9. The lifting plate 12 has a lifting hole 13 extending in the vertical direction. The first support shaft 14 is inserted into the lifting hole 13. The lifting plate 12 is mounted on the first support shaft 14 and can move up and down relative to the first support shaft 14. The first support shaft 14 is threaded. The first nut 15 is screwed onto the first support shaft 14 to lock the lifting plate 12 at a fixed height. The angle adjustment assembly 16 is connected to the height adjustment assembly 11. Specifically, the bellows 9 has a window 3 that faces the mounting structure. When the distance between the planar infrared system 4 and the material needs to be adjusted, the first nut 15 is manually loosened, the entire planar infrared system 4 is lifted or lowered, and then the first nut 15 is tightened. Manual height adjustment is relatively simple and easy to install.

[0041] In one embodiment, the angle adjustment assembly 16 includes a base 17, a second support shaft 18, and a second nut 19. The second support shaft 18 is connected to the bottom of the lifting plate 12. The base 17 is rotatably assembled with the second support shaft 18. The second support shaft 18 is provided with threads. The second nut 19 is used to be screwed onto the second support shaft 18 to lock the base 17 at a fixed angle. The planar infrared element 7 is connected to the base 17. Specifically, when the surface of the material is tilted, causing the infrared light emitted by the planar infrared system 4 to be unable to properly illuminate the material, the second nut 19 is manually loosened to adjust the tilt angle of the base 17 so that the infrared plate 8 is parallel to the material surface. The second nut 19 is then tightened again to fix the base 17 at the corresponding angle.

[0042] In one embodiment, the conveying system 6 includes a conveyor belt 20, wherein the conveyor belt 20 forms the material conveying platform, and the upper surface of the conveyor belt 20 forms the material conveying surface. The conveyor belt 20 has a simple structure and reduces costs.

[0043] The working principle of the infrared oven in the embodiment of the present application is as follows:

[0044] When the material needs to be dried, the conveying system 6 is started, and the material is placed on the conveyor belt 20. The conveyor belt 20 transports the material to the drying chamber 2 of the oven, and then the conveyor belt 20 is controlled to stop so that the material stays in the drying chamber 2 so that the infrared light emitted by the planar infrared element 7 can irradiate the surface of the material. When the distance between the planar infrared system 4 and the material is too large or too small, the first nut 15 is manually loosened, and the entire planar infrared system 4 is lifted up or pulled down, and then the first nut 15 is tightened to fix the planar infrared system 4 at a suitable height. When the surface of the material is tilted, causing the planar infrared element 7 to When the infrared light emitted by the system 4 cannot irradiate the material well, manually loosen the second nut 19 and adjust the inclination angle of the base 17 so that the infrared plate 8 is parallel to the surface of the material. Then tighten the second nut 19 again to fix the base 17 at the corresponding angle. While the material is irradiated by the infrared light, start the wind field system 5 and blow hot air into the drying chamber 2 through the bellows 9 to form a hot air circulation in the drying chamber 2. The planar infrared system 4 is combined with the wind field system 5 to dry the material as a whole. After the material has been dried for a certain period of time, start the conveyor belt 20 again, and the conveyor belt 20 brings the dried material out of the infrared oven.

[0045] According to the infrared drying oven of the embodiment of the present application, the infrared light emitted by the infrared plate 8 of the planar infrared system 4 can penetrate into the interior of the material and dry the interior of the material. The hot air flow generated by the wind field system 5 in the drying chamber 2 can dry the surface of the material. The planar infrared system 4 and the wind field system 5 cooperate to quickly dry the entire material, shorten the drying time, and improve the drying efficiency.

[0048] In the infrared oven provided by the fourth embodiment of the present application, all the infrared plates 8 of each planar infrared element 7 have different shapes.

[0049] In an infrared oven provided in the fifth embodiment of the present application, the height adjustment component 11 can also be a lifting cylinder, the top of the lifting cylinder is connected to the bellows 9, and the base 17 of the angle adjustment component 16 is connected to the bottom of the lifting cylinder.
