Description

Technical Field

[0001] This utility model relates to the technical field of aluminum-plastic film baking equipment, specifically to an aluminum-plastic film oven. Background Technology

[0002] Aluminum-plastic film is a multi-layer composite film consisting of an outer nylon layer (ON), an adhesive, an intermediate aluminum foil layer (Al), an adhesive, and an inner heat-sealing layer (CPP). In the production process of aluminum-plastic film, a passivation solution (containing passivating agent, water, and alcohol) needs to be applied to the aluminum-plastic film, and then it is heated and dried in a high-temperature oven (300℃). When the moisture and alcohol evaporate rapidly, the surface of the aluminum-plastic film contains only the passivating agent.

[0003] Ovens are typically equipped with air knives, which use the hot air blown out by the air knives to heat the surface of the aluminum-plastic film. In order to make the passivating agent quickly reach the required reaction temperature on the film surface, the traditional method mainly involves increasing the air volume of the air knife and the temperature of the hot air. However, this method has a long heating time and high energy consumption. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing an aluminum-plastic film oven that employs a two-way heating method combining hot air and thermal radiation. This shortens the time it takes for the passivating agent to reach the required film surface reaction temperature, thereby reducing the heating time of the aluminum-plastic film and decreasing energy consumption.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An aluminum-plastic film oven includes an oven and a first heating component and a second heating component disposed inside the oven. A channel for the aluminum-plastic film to pass through is formed between the first heating component and the second heating component. Both the first heating component and the second heating component include a plurality of air blades and a plurality of infrared lamps. The air blades and infrared lamps are alternately distributed, and the air outlets of the air blades face the channel.

[0007] By setting a first heating component and a second heating component inside the oven, a channel is formed between the first heating component and the second heating component for the aluminum-plastic film to pass through. Both the first heating component and the second heating component include several air knives and several infrared heating lamps, which are distributed alternately. The air outlets of the air knives face the channel. During baking, the hot air blown out by the air knives heats the aluminum-plastic film on the one hand, and the infrared rays emitted by the infrared heating lamps radiate the aluminum-plastic film on the other hand. The aluminum foil inside absorbs the infrared rays, causing the aluminum-plastic film to heat up. Thus, a two-way heating method of hot air + thermal radiation is adopted, which shortens the time for the passivating agent to reach its required film surface reaction temperature, thereby shortening the heating time of the aluminum-plastic film and reducing energy consumption.

[0008] As a preferred embodiment, the infrared light emitted by the infrared lamp has a wavelength of 2μm to 20μm.

[0009] As a preferred embodiment, the infrared light emitted by the infrared lamp has a wavelength of 8μm to 12μm.

[0010] As a preferred embodiment, the length A of the infrared lamp is 1050mm to 1150mm.

[0011] As a preferred embodiment, the width B of the infrared heating lamp is 180mm to 220mm.

[0012] As a preferred embodiment, the distance d between the air knife and the infrared heating lamp is 40mm to 60mm.

[0013] As a preferred embodiment, the height h of the channel in the vertical direction is 230mm to 270mm.

[0014] As a preferred embodiment, the channel is a straight channel, and the air knives and infrared lamps are arranged in a straight line.

[0015] As a preferred embodiment, the air blade on the first heating component is positioned directly opposite the infrared lamp on the second heating component, and the infrared lamp on the first heating component is positioned directly opposite the air blade on the second heating component.

[0016] As a preferred embodiment, the oven includes an upper oven and a lower oven, with the first heating element disposed in the upper oven and the second heating element disposed in the lower oven.

[0017] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, by setting a first heating component and a second heating component inside the oven, a channel is formed between the first heating component and the second heating component for the aluminum-plastic film to pass through. Both the first heating component and the second heating component include several air knives and several infrared heating lamps, which are distributed alternately. The air outlet of the air knife faces the channel. During baking, the hot air blown out by the air knife heats the aluminum-plastic film on the one hand, and the infrared rays emitted by the infrared heating lamps radiate the aluminum-plastic film on the other hand. The aluminum foil inside absorbs the infrared rays, causing the aluminum-plastic film to heat up. Thus, a two-way heating method of hot air + thermal radiation is adopted, which shortens the time for the passivating agent to reach its required film surface reaction temperature, thereby shortening the heating time of the aluminum-plastic film and reducing energy consumption.

[0018] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments: Attached Figure Description

[0020] Figure 2 This is a bottom view of the assembly of the first heating component according to an embodiment of the present invention.

[0021] Explanation of reference numerals in the attached diagram:

[0023] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1-2 As shown, this utility model discloses an aluminum-plastic film oven 10, including an oven 10, and a first heating component 11 and a second heating component 12 disposed within the oven 10. A channel 13 for an aluminum-plastic film 20 to pass through is formed between the first heating component 11 and the second heating component 12. The first heating component 11 and the second heating component 12 each include a plurality of air blades 111 and a plurality of infrared baking lamps 112. The air blades 111 and infrared baking lamps 112 are alternately distributed. The air outlet of the air blades 111 faces the channel 13. The air blades 111 and infrared baking lamps 112 can be alternately distributed along the length direction of the channel 13, and the air blades 111 and infrared baking lamps 112 can also be alternately distributed along the width direction of the channel 13.

[0026] The infrared lamp 112 emits infrared light with a wavelength of 2μm to 20μm. By using an infrared lamp 112 with an infrared wavelength of 2μm to 20μm, infrared light in this wavelength range can be absorbed by the aluminum foil, thereby helping to heat the aluminum-plastic film 20.

[0027] The infrared lamp 112 emits infrared light with a wavelength of 8μm to 12μm. By using an infrared lamp 112 with an infrared wavelength of 8μm to 12μm, the aluminum foil has the highest absorption rate of infrared light in this wavelength range, which improves the heating efficiency of the aluminum-plastic film 20, greatly shortens the heating time for the passivating agent to quickly reach the required film surface reaction temperature, and can reduce the length of the oven 10 by half, thus reducing energy consumption.

[0028] The length A of the infrared lamp 112 is 1050mm to 1150mm.

[0029] The width B of the infrared heating lamp 112 is 180mm to 220mm.

[0030] The distance d between the air knife 111 and the infrared heating lamp 112 is 40mm to 60mm. By adopting a distance d of 40mm to 60mm, the air knife 111 and the infrared heating lamp 112 have a compact structure, occupy less space, and heat the aluminum-plastic film 20 more evenly.

[0031] The height h of the channel 13 in the vertical direction is 230mm to 270mm.

[0032] The channel 13 is a straight channel 13, and the air blades 111 and the infrared lamps 112 are all arranged in a straight line.

[0033] The air knife 111 on the first heating component 11 is directly opposite the infrared lamp 112 on the second heating component 12, and the infrared lamp 112 on the first heating component 11 is directly opposite the air knife 111 on the second heating component 12. By setting the air knife 111 on the first heating component 11 to be directly opposite the infrared lamp 112 on the second heating component 12, the air knife 111 blows hot air toward the aluminum-plastic film 20, causing the aluminum-plastic film 20 to arch toward the infrared lamp 112, shortening the distance between the aluminum-plastic film 20 and the infrared lamp 112, and making the aluminum-plastic film 20 have a higher heat absorption efficiency.

[0034] The oven 10 includes an upper oven 101 and a lower oven (not shown). The first heating component 11 is disposed in the upper oven 101, and the second heating component 12 is disposed in the lower oven. By setting up the upper oven 101 and the lower oven, it is convenient to assemble the first heating component 11 into the upper oven 101 and to assemble the second heating component 12 into the lower oven.

[0035] In summary, this utility model, by setting a first heating component 11 and a second heating component 12 inside the oven 10, forms a channel 13 between the first heating component 11 and the second heating component 12 for the aluminum-plastic film 20 to pass through. Both the first heating component 11 and the second heating component 12 include several air knives 111 and several infrared lamps 112, which are alternately distributed. The air outlet of the air knife 111 faces the channel 13. During baking, the hot air blown out by the air knife 111 heats the aluminum-plastic film 20 on the one hand, and the infrared rays emitted by the infrared lamps 112 radiate the aluminum-plastic film 20 on the other hand. The aluminum foil inside absorbs the infrared rays, causing the aluminum-plastic film 20 to heat up. Thus, a two-way heating method of hot air + thermal radiation is adopted, which shortens the time for the passivating agent to reach its required film surface reaction temperature, thereby shortening the heating time of the aluminum-plastic film 20 and reducing energy consumption.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
