Description

Technical Field

[0001] This utility model relates to the field of oven equipment technology, and in particular to the air supply and return device of an air-floating oven. Background Technology

[0002] With the rapid development of oven technology, increasingly higher requirements are being placed on the drying quality and efficiency of substrates (such as coated films, coated paper, etc.).

[0003] Traditional drying ovens often use direct heating during the drying process. While this method can dry the substrate, it suffers from uneven drying, high energy consumption, and can easily cause scratches, wrinkles, or curling on the substrate.

[0004] Furthermore, traditional drying ovens often lack precise temperature control during the drying process, leading to unstable drying results and impacting product yield and quality. Simultaneously, excess hot air discharged from the oven is often not effectively utilized, resulting in energy waste.

[0005] Therefore, in order to solve the above problems, it is urgent to develop an air supply and return device for an air-floating oven. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides an air supply and return device for an air flotation oven, which can use air flotation technology to keep the substrate in a suspended state during the drying process, avoiding direct contact with the internal structure of the oven, thereby reducing the risk of scratches, wrinkles and warping; at the same time, the air supply and return device recirculates some of the excess hot air discharged from the oven, achieving uniform drying of the substrate and efficient energy utilization.

[0007] The technical solution adopted in this utility model is as follows: an air supply and return device for an air-floating oven, used to connect with the oven mechanism, comprising:

[0008] The air supply mechanism is connected to one side of the oven mechanism; the air supply mechanism includes a blower, the blower is equipped with a drive fan, the air inlet of the blower is connected to the fresh air inlet mechanism through a flexible connecting pipe, and the air outlet of the blower is connected to the oven mechanism through an air supply pipeline.

[0009] The return air mechanism is connected to the other side of the oven mechanism; the return air mechanism includes a first oven return air pipe and a second oven return air pipe, the first oven return air pipe is connected to the lower oven body, and the second oven return air pipe is connected to the upper oven body.

[0010] The mixed gas discharged from the return air duct of the first oven passes through the first return air connecting pipe and then merges with the mixed gas discharged from the return air duct of the second oven. The merged mixed gas is divided into two paths, one of which is discharged through the exhaust port, and the other path re-enters the fresh air intake mechanism through the second return air connecting pipe. Both the first oven return air duct and the second oven return air duct are equipped with return air valves.

[0011] As a further improvement to the above technical solution:

[0012] Preferably, the air supply duct includes a first air supply connecting pipe connected to the air outlet of the blower. The gas flow of the first air supply connecting pipe is divided into two paths on the other side. One path sends air into the upper oven body through the first oven air supply pipe, and the other path sends air into the lower oven body through the second oven air supply pipe after passing through the second and third air supply connecting pipes in sequence. Both the first oven air supply pipe and the second oven air supply pipe are equipped with air supply valves.

[0013] More preferably, the first air supply connecting pipe, the second air supply connecting pipe, the third air supply connecting pipe, the first oven air supply pipe, and the second oven air supply pipe in the air supply pipeline together form a flexible branching air supply network. By opening or closing the air supply valve, the air supply volume and air supply time of each branch pipeline can be precisely controlled.

[0014] Preferably, the blower in the air supply mechanism provides power by driving a fan to ensure that the gas is stably delivered to the oven mechanism.

[0015] More preferably, the bottom of the blower is provided with a shock-absorbing pad, which is used to reduce the vibration and noise of the blower during operation, and improve the overall stability and service life of the blower mechanism.

[0016] Preferably, the return air pipes of the first and second ovens in the return air mechanism can be precisely controlled by opening or closing the return air valves, thereby assisting in regulating the temperature and humidity inside the oven mechanism.

[0017] Preferably, both the supply air valve and the return air valve are electrically connected to the control mechanism; the control mechanism further controls the supply air time and supply air volume by controlling the opening or closing of the supply air valve; the control mechanism further controls the return air time and return air volume by controlling the opening or closing of the return air valve.

[0018] This utility model has the following advantages:

[0019] (1) Precise air supply control: Through the coordinated operation of air supply pipelines, air supply valves, upper and lower drying oven components and upper and lower blowing units, the air supply volume and air supply time can be precisely controlled to ensure that the air volume and temperature distribution in each area inside the drying oven are uniform, thereby greatly improving drying efficiency and drying quality.

[0020] (2) The design of the return air mechanism enables the hot air of the oven components to be effectively collected and processed. Some of the hot air can be returned to the fresh air system for recycling, which not only reduces energy waste but also reduces emissions and meets the requirements of green production.

[0021] (3) Vibration and noise reduction design: The vibration damping pads at the bottom of the blower of this utility model effectively reduce the vibration and noise during the operation of the equipment, and improve the stability and service life of the device. Attached Figure Description

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] like Figures 1-5 The diagram shows a schematic of the air supply and return device of an air-floating oven according to an embodiment of this application. The air supply and return device of the air-floating oven provided in an embodiment of this application includes an oven mechanism 100, an air supply mechanism 200, an air supply duct 300, a fresh air inlet mechanism 400, a return air mechanism 500, a flexible connecting pipe 600, and a control mechanism 700.

[0042] In this embodiment, the oven mechanism 100 includes an upper oven assembly 110 and a lower oven assembly 120. The upper oven assembly 110 has an upper oven body 111 and an upper air blowing unit 112, and the lower oven assembly 120 has a lower oven body 121 and a lower air blowing unit 122; as Figure 5 As shown, the upper blowing unit 112 and the lower blowing unit 122 are arranged alternately, with the air blowing direction of the upper blowing unit 112 pointing downwards and the air blowing direction of the lower blowing unit 122 pointing upwards.

[0043] like Figure 2The diagram illustrates the cooperative structure of the air supply mechanism 200 and the air supply duct 300 of this invention. In this embodiment, the air supply mechanism 200 is disposed on one side of the oven mechanism 100 and is connected to the oven mechanism 100. Specifically, the air supply mechanism 200 includes a blower 210, which has a drive fan 220 inside to provide air supply power. The air inlet of the blower 210 is connected to the fresh air inlet mechanism 400 through a flexible connecting pipe 600, and the air outlet of the blower 210 is connected to the oven mechanism 100 through the air supply duct 300. A shock-absorbing pad 230 is also provided at the bottom of the blower 210 to reduce vibration and noise during operation of the blower 210, thereby improving the overall stability and service life of the air supply mechanism 200.

[0044] Furthermore, the air supply duct 300 specifically includes a first air supply connection pipe 310 connected to the air outlet of the blower 210. The gas flow of the first air supply connection pipe 310 is divided into two paths on the other side: one path sends air into the upper oven body 111 through the first oven air supply pipe 320, and the other path sends air into the lower oven body 121 through the second oven air supply pipe 350 after passing through the second air supply pipe 330 and the third air supply connection pipe 340 in sequence. Both the first oven air supply pipe 320 and the second oven air supply pipe 350 are equipped with air supply valves 360 to precisely control the air supply volume and air supply time of each branch pipe.

[0045] In this embodiment, the fresh air intake mechanism 400 includes a fresh air inlet 410, a fresh air filter 420, a pre-filter 430, a heating component 440, and a humidification component 450. Fresh air enters the fresh air intake mechanism 400 through the fresh air inlet 410, passes through the fresh air filter 420 and the pre-filter 430 in sequence, and then the temperature and humidity are regulated by the heating component 440 and the humidification component 450. Finally, the air is delivered to the air supply mechanism 200 through the flexible connecting pipe 600 on the air outlet side.

[0046] like Figure 3The diagram shows a schematic representation of the return air mechanism 500 of this invention. In this embodiment, the return air mechanism 500 is located on the other side of the oven mechanism 100 and is connected to it. The return air mechanism 500 includes a first oven return air pipe 510 and a second oven return air pipe 530. The first oven return air pipe 510 is connected to the lower oven body 121, and the second oven return air pipe 530 is connected to the upper oven body 111. The mixed gas discharged through the first oven return air pipe 510 passes through the first return air connecting pipe 520 and then merges with the mixed gas discharged through the second oven return air pipe 530. The merged mixed gas is divided into two paths: one path is discharged through the exhaust port 550, and the other path re-enters the fresh air inlet mechanism 400 through the second return air connecting pipe 540 for reuse. Both the first oven return air pipe 510 and the second oven return air pipe 530 are equipped with return air valves 560 to precisely control the return air volume and return air time.

[0047] In this embodiment, the control mechanism 700 is electrically connected to both the air supply valve 360 ​​and the return air valve 560. The control mechanism 700 allows for flexible control of the opening and closing of the air supply valve 360 ​​and the return air valve 560, thereby further controlling the air supply time, air supply volume, return air time, and return air volume, achieving precise adjustment of the temperature and humidity within the oven mechanism 100.

[0048] The air supply and return system of the air-floating oven in this embodiment achieves uniform temperature and humidity distribution within the oven through precise air supply and return control, thereby improving drying efficiency and quality. Simultaneously, the recycling of hot air reduces energy consumption and pollution emissions, meeting the requirements of green production.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
