Description

Technical Field

[0001] This utility model relates to the field of composite material drying oven technology, specifically an oven used for preparing multilayer coated composite materials. Background Technology

[0002] The development of modern high technology is inseparable from composite materials, which play a vital role in the advancement of modern science and technology. The depth of research and the breadth of application of composite materials, as well as the speed and scale of their production development, have become important indicators for measuring a country's level of scientific and technological advancement.

[0003] A search of existing technology reveals that publication number CN209549897U discloses an oven for preparing multilayer coated composite materials. The oven includes an oven support and a chamber, with the chamber fixed to the support. The chamber includes a heating and drying oven and a control chamber. The heating and drying oven is divided into a front oven, a middle oven, and a rear oven, with transverse baffles between adjacent oven sections. Each of the front, middle, and rear ovens is equipped with an electric heater and a temperature equalization device. The control chamber controls the heating of the electric heaters, and the temperature equalization device evens out the temperature of each oven section. After the core film is coated with adhesive, it undergoes uniform heating and drying in the oven in three stages.

[0004] The comparative document describes a segmented heating oven with transverse baffles between each segment to ensure proper heating of the coated core film in each working area. Each segment also includes a temperature equalization device to ensure uniform temperature distribution throughout the oven, guaranteeing even heating of the film material surface and thus ensuring successful multilayer film lamination in subsequent processes. However, when new material is removed or added, air escapes from the oven, causing heat loss and a drop in internal temperature. Utility Model Content

[0005] The purpose of this invention is to provide an oven for preparing multilayer coated composite materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a drying oven body, with an inlet / outlet on one side of the drying oven body. Two closed doors are movably connected to the inlet / outlet, and a linkage device is provided in the middle of the closed doors. An air inlet is provided on the inner wall of the drying oven body, with a transmission pipe at the upper end of the air inlet. An air supply device is provided at one end of the transmission pipe, and a horizontal air outlet and a vertical air outlet are provided at the lower end of the air supply device. A sealing block is provided inside the horizontal air outlet, and a rotating trolley is provided at the bottom of the inner cavity of the drying oven body.

[0007] Preferably, the air inlet is located at the rear end of the inner cavity of the drying oven body, and a vertical air duct is provided on the outside of the air inlet, which is connected to the transmission pipe.

[0008] Preferably, the conveying air device is equipped with a conveying fan inside, one end of which is connected to the conveying pipe, and the other end of which is connected to the horizontal air outlet and the vertical air outlet. A guide vane is provided below the conveying fan.

[0009] Preferably, the linkage device includes a rotating shaft, which is disposed on one side of the closed door. A drive tube is rotatably connected to the rotating shaft. The drive tube is eccentrically disposed with respect to the rotating shaft. A sliding block is provided on one side of the drive tube, and the sliding block is movably connected to the sealing block.

[0010] Preferably, a sliding groove is provided in the vertical air outlet of the drying box body, and a sealing block is slidably connected in the sliding groove. An inclined surface is provided on one side of both the sealing block and the sliding block, and the two inclined surfaces are adapted to each other. A sealing airbag is provided on the other side of the sealing block.

[0011] Preferably, the lower end of the trolley is provided with a slide rail, which is fixedly connected to the inner surface of the drying chamber body.

[0012] Compared with existing technologies, the advantages of this invention are: when the oven door is opened, an airflow fan blows downwards at the doorway, blocking the airflow inside the oven and preventing it from flowing out, thus maintaining heat preservation. Simultaneously, it allows air to circulate within the oven, maintaining a uniform internal temperature. When the closed door is opened, it drives a rotating shaft to rotate. An eccentrically positioned drive tube on the shaft presses against a sliding block, causing the sliding block to push a sealing block outwards. As the sealing block moves outwards, it blocks the vertical air outlet, allowing airflow only from the horizontal air outlet, blowing downwards at the oven's outlet to prevent internal air from flowing outwards, thus maintaining heat preservation. When the closed door is closed, the vertical air outlet is open, and the fan drives airflow, drawing air in from the air inlet and blowing it out from both the vertical and horizontal air outlets, effectively promoting airflow within the oven.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0020] Example: The device includes a drying oven body 1. An inlet / outlet 2 is provided on one side of the drying oven body 1, and two sealing doors 3 are movably connected to the inlet / outlet 2. The sealing doors 3 effectively seal the drying oven body 1, ensuring the airtightness of the drying process. A linkage device 4 is provided in the middle of the sealing doors 3. The linkage device 4 can adjust the airflow when the sealing doors 3 rotate. An air inlet 5 is provided on the inner wall of the drying oven body 1. A transmission pipe 6 is provided at the upper end of the air inlet 5, and an air supply device 7 is provided at one end of the transmission pipe 6. The air supply device 7 can move the gas inside the drying oven body 1. A horizontal air outlet 8 and a vertical air outlet 9 are provided at the lower end of the air supply device 7. A sealing block 17 is provided inside the horizontal air outlet 8. A trolley 10 is provided at the bottom of the inner cavity of the drying oven body 1. The trolley 10 can be used to load the items to be dried.

[0021] The air inlet 5 is located at the rear end of the inner cavity of the drying chamber body 1. A vertical air duct 11 is provided on the outside of the air inlet 5, and the vertical air duct 11 is connected to the transmission pipe 6. After the vertical air duct 11 inputs the air from the drying chamber, it is transmitted to the front of the drying chamber through the transmission pipe 6.

[0022] The air supply device 7 is equipped with a transmission fan 12. One end of the transmission fan 12 is connected to the transmission pipe 6, and the other end of the transmission fan 12 is connected to the horizontal air outlet 8 and the vertical air outlet 9. A guide vane 13 is provided below the transmission fan 12. The transmission fan 12 can compress the airflow and finally transmit it from the horizontal air outlet 8 and the vertical air outlet 9.

[0023] The linkage device 4 includes a rotating shaft 14, which is disposed on one side of the closed door 3. A drive tube 15 is rotatably connected to the rotating shaft 14, and the drive tube 15 is eccentrically disposed with respect to the rotating shaft 14. A sliding block 16 is provided on one side of the drive tube 15, and the sliding block 16 is movably connected to the blocking block 17. When the rotating shaft 14 is adjusted, the drive tube 15 can push the sliding block 16 to move.

[0024] A sliding groove is provided in the vertical air outlet 9 of the drying oven body 1. A sealing block 17 is slidably connected in the sliding groove. Both the sealing block 17 and the sliding block 16 have inclined surfaces on one side, and the two inclined surfaces are adapted to each other.

[0026] After the sealing door 3 is opened, the sealing door 3 drives the rotating shaft 14 to rotate. The eccentrically positioned drive tube 15 on the rotating shaft 14 presses against the sliding block 16, causing the sliding block 16 to press against the sealing block 17 and move it outward. When the sealing block 17 moves outward, it blocks the vertical air outlet 9, allowing airflow to only exit from the horizontal air outlet 8 and blow downward at the outlet of the oven body, preventing internal air from flowing outward and thus maintaining the temperature. When the sealing door 3 is closed, the vertical air outlet 9 is open, and the transmission fan 12 drives the airflow, drawing air in through the air inlet 5 and then blowing it out from both the vertical air outlet 9 and the horizontal air outlet 8, thereby promoting airflow inside the oven body.
