DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1: Figures 1 to 5 As shown, a coating machine oven air nozzle structure includes an air guide shell 1, an air guide pipe 2, a lifting member 3 and a hanging member 4. The air guide shell 1 and the air guide pipe 2 are made of stainless steel. The air guide pipe 2 is detachably mounted on the lower end of the air guide shell 1. The left and right sides of the air guide shell 1 are respectively fixedly mounted with lifting members 3, and hanging members 4 are evenly arranged above the lifting members 3. The hanging members 4 are detachably mounted on the upper part of the air guide shell 1. The hanging members 4 are connected to the lifting members 3. The hanging members 4 are hung on the oven to complete the installation of the entire air nozzle structure. The lifting member 3 is arranged to push the hanging member 4 to move up and down, and the hanging member 4 is fixedly hung on the oven. Since the lifting member 3 is fixedly mounted on the air guide shell 1, the distance between the air guide shell 1 and the bottom foil can be adjusted by adjusting the lifting member 3 to achieve the desired drying effect. At the same time, the setting of the air guide pipe 2 also increases the wind speed, which is beneficial to improving the drying efficiency of the foil.

[0033] The oven of the prior art is large in size, partly because the heating pack occupies a large space, and partly because the air nozzle is large in size, which makes the energy consumption required for drying foils with the same performance greater. At the same time, the structure of the air nozzle, the air outlet speed, the air outlet volume and the air outlet direction will have a great influence on the drying rate and drying effect. The air nozzle structure of the prior art has a square cross-section and a large size. The blowing drying efficiency is average, which will affect the drying capacity of the oven.

[0034] In order to reduce the volume size of the nozzle structure, the cross-sectional shape of the air guide housing 1 of this embodiment is set to a T-shape, which saves space occupancy and material compared to a square shape, which is beneficial to reducing energy consumption. The air guide housing 1 includes a mounting portion 11 and an air guide portion 12, the mounting portion 11 is connected to the air outlet of the oven, and the air guide portion 12 is used to guide the wind to the foil. The air guide portion 12 is located below the mounting portion 11, and the air guide portion 12 is arranged vertically to the mounting portion 11, so that the wind in the air guide housing 1 can guide the foil faster, which is beneficial to improving the drying efficiency of the nozzle.

[0035] Since the cross-sectional shape of the air guide shell 1 is T-shaped, when the wind flows from the mounting portion 11 to the air guide portion 12, the cross-sectional area of ​​the flow decreases and the wind speed increases. At the same time, the impact flow of the wind will generate turbulence, thus having a higher heat transfer and mass transfer coefficient, shortening the drying time and improving the drying efficiency.

[0036] Furthermore, an air guide port 121 is provided at the lower end of the air guide portion 12, and an air guide pipe 2 is arranged in the air guide port 121. The air guide pipe 2 is cylindrical. The air guide pipe 2 is provided so that the wind is blown out from the gap between the air guide pipe 2 and the air guide shell 1, thereby increasing the wind speed and achieving a better drying effect on the foil.

[0037] In order to make the wind speed of the air guide port 121 adjustable as needed, adjustment holes 1211 for adjusting the position of the air guide pipe 2 are provided at both ends of the air guide port 121. The adjustment holes 1211 are in a long strip shape. The two ends of the air guide pipe 2 are detachably mounted on the adjustment holes 1211 on both sides. The position of the air guide pipe 2 can be adjusted up and down as needed. The distance between the air guide pipe 2 and the two sides of the air guide port 121 will also change with the movement of the air guide pipe 2. The smaller the distance, the greater the wind speed, thereby achieving the required drying effect for the foil, thereby improving the practicality of the structure.

[0038] Furthermore, the same spacing distance is provided between the air guide pipe 2 and both sides of the air guide housing 1, so that the air outlet rates on both sides can be the same, ensuring the uniformity of the wind speed at the air guide port 121, which is beneficial to improving the drying effect of the foil.

[0039] In order to increase the air outlet area of ​​the air guide port 121, the air guide port 121 is arranged to have an outward-facing octave structure, which can increase the drying area and improve the drying efficiency.

[0040] The hanging component 4 of this embodiment includes a hanging portion 41, a hanging plate 42 and a connecting plate 43. The hanging portion 41 is installed above the hanging plate 42, and the connecting plate 43 is vertically installed at the lower end of the hanging plate 42. The connecting plate 43 is connected to the lifting component 3 and is arranged vertically with the lifting component 3, so that the lifting component 3 can push the connecting plate 43 to prompt the hanging component 4 to move up and down in the vertical direction. The hanging portion 41 is a hook and can be directly hung on the oven, thereby improving the convenience of installation.

[0041] In order to enable the air guide shell 1 to be adjusted up and down in the vertical direction, a plurality of mounting holes 421 for adjusting the position of the air guide shell 1 are provided on the mounting plate 42. The mounting member 4 is mounted on the upper end of the air guide shell 1 by bolt connection. The air guide shell 1 can adjust the installation position up and down as needed, so that the distance between the air guide shell and the foil material can be adjusted, thereby improving the flexibility of the structure.

[0042] The lifting member 3 of this embodiment includes a lifting rod 31 and a fixing plate 32. The lifting rod 31 is a screw rod. The fixing plate 32 is vertically mounted on the side end of the air guide shell 1. The lifting rod 31 is threadedly connected to the fixing plate 32. The connecting plate 43 is close to the top of the lifting rod 31. The lifting rod 31 can be rotated to push the connecting plate 43. Thus, the hanging member 4 is moved by adjusting the bolts of the lifting member 3, so that the distance between the nozzle structure and the foil can be adjusted.

[0043] A coating machine oven air nozzle structure in the present embodiment is provided with an air guide shell 1, an air guide pipe 2, a lifting component 3 and a hanging component 4. The air guide pipe 2 is installed at the lower end of the air guide shell 1, and the lifting components 3 are respectively installed on both sides of the air guide shell 1. The hanging component 4 is arranged on the upper part of the air guide shell 1, and the hanging component 4 is connected to the lifting component 3. The hanging component 4 is located above the lifting component 3, so that the air nozzle can adjust the distance between it and the foil to be dried, and the wind speed can be adjusted through the air guide pipe 2. The structure is simple and clever, and is easy to install, which is conducive to reducing the structural size, reducing energy consumption, and improving the drying rate and drying effect of the air nozzle, which is conducive to the application and promotion of the above-mentioned coating machine oven air nozzle structure in the field of coating machine equipment technology.

[0044] Example 2: Figure 6 As shown, the feature that distinguishes this embodiment from Embodiment 1 is that: in this embodiment, a coating machine oven air nozzle structure is provided, and the air guide port 121 of the air guide shell 1 is in an inner eight-shaped structure. Compared with the air guide port 121 in an outer eight-shaped structure, the distance between the air guide duct 2 and the two sides of the air guide port 121 is smaller, thereby promoting a faster wind speed between the air guide duct 2 and the air guide port 121. The air guide port 121 in the inner eight-shaped structure makes the opening at the bottom end of the air guide port 121 smaller than that in the outer eight-shaped structure, and also further increases the wind speed at the bottom end of the air guide port 121. By providing the air guide port 121 with this structure, the wind speed of the air blown out from the air nozzle is effectively improved, the drying of the foil is accelerated, and the drying efficiency and drying effect of the air nozzle on the foil are improved.

[0045] Embodiment 3: The features that distinguish this embodiment from Embodiment 1 are as follows: In this embodiment, a coating machine oven nozzle structure is provided with an air duct 2 as an infrared heating tube. On the one hand, before the wind inside the nozzle blows toward the foil, the air duct 2 can heat the wind to ensure that the wind blown out from the nozzle has good heat, thereby improving the drying effect; on the other hand, the air duct 2 is arranged in the air duct 121, and is close to the foil below the air duct 121. The air duct 2 can directly heat the foil, thereby improving the drying efficiency. At the same time, the air duct 2 is an infrared heating tube, which has an impact on the selection of the oven heating pack. Since the air duct 2 already has a heating function, the oven can select a heating pack with a small heating power, which can effectively reduce energy consumption and improve the drying efficiency and drying effect of the air nozzle on the foil.

[0046] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.

[0047] Although the following terms are used more frequently in this article: 1, air guide housing; 11, mounting portion; 12, air guide portion; 121, air guide port; 1211, adjustment hole; 2, air guide duct; 3, lifting member; 31, lifting rod; 32, fixing plate; 4, hanging member; 41, hanging portion; 42, hanging plate; 421, mounting hole; 43, connecting plate, etc., the possibility of using other terms is not excluded.
