Its structure includes the following features:
[0003] 1. Heating element, the most common heating element is heating wire or heating tube;
[0004] 2. The fan is the power source for ventilation circulation, which can effectively transport hot air to every corner of the box; axial flow fans have a large air volume and are suitable for situations that require rapid circulation of hot air;
[0005] 3. Shelf (display shelf) structure: Shelves are generally designed with a multi-layer structure, and the number of layers can be adjusted according to the height of the cabinet and the user's needs, such as 3-5 layers.

[0006] 4. The control panel is located on the front or side of the chamber for easy operation by the user to set the parameters of the electric heating constant temperature drying oven.
[0007] During the drying process of composite food packaging bags, the drying chamber needs to exchange gases with the outside air to a certain extent. This is usually achieved through ventilation vents to circulate and refresh the air inside the chamber in order to maintain the reasonable air pressure and humidity environment required for drying. If there is too much dust in the environment where the equipment is located, the dust will enter the chamber through the ventilation vents, which will have an adverse effect on the components inside the chamber and the composite food packaging bags. This application proposes a solution to this problem by adding a filter box at the ventilation vent to block the entry of dust. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides an electric thermostatic drying oven for composite food packaging bags, which solves the technical problem that if there is too much dust in the environment where the equipment is located, the dust will enter the oven through the ventilation vents and have an adverse effect on the components inside the oven and the composite food packaging bags.

[0024] This application provides an electric thermostatic drying oven for composite food packaging bags, which effectively solves the technical problem that if there is too much dust in the environment where the equipment is located, the dust will enter the oven through the ventilation vents and have an adverse effect on the components inside the oven and the composite food packaging bags.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that if there is too much dust in the environment where the equipment is located, the dust will enter the box through the ventilation vents and have an adverse effect on the components and composite food packaging bags inside the box. The overall idea is as follows:
[0027] To address the problems existing in the prior art, this utility model provides a composite food packaging bag electric constant temperature drying oven, including a drying oven body 1, an operation panel 15 fixedly installed on the outside of the drying oven body 1, a filter box 2 for blocking dust provided on the outside of the drying oven body 1, a fixing bracket 3 for installing the filter box 2 fixedly installed on the outside of the filter box 2, a mounting block 4 for installing the filter box 2 provided on the outside of the drying oven body 1, the fixing bracket 3 snapping into the outside of the mounting block 4, and a side of the drying oven body 1 near the operation panel 15 provided for connecting with the fixing bracket. The mounting plate 5 is connected to the 3rd mounting plate. The external sliding connection of the mounting plate 5 is a slider 6 that restricts the movement of the fixing frame 3. By setting the filter box 2, in conjunction with the mounting plate 5, when the drying oven is not in use, the connection between the fixing frame 3 and the mounting block 4 is released. At this time, the fixing frame 3 is connected to the mounting plate 5. At this time, the filter box 2 covers the operation panel 15, reducing the probability of damage. When the drying oven is in use, the filter box 2 is connected to the mounting block 4 through the fixing frame 3 to cover the ventilation opening, preventing dust from entering and affecting the components and food packaging bags inside the oven, thus ensuring the normal use of the equipment.
[0028] The mounting plate 5 is provided with a helical spring 7 for supporting the slider 6. The slider 6 is fixedly connected to the outside of the helical spring 7. The mounting plate 5 is provided with a receiving groove 8 for accommodating the helical spring 7. The helical spring 7 is fixedly connected to the inside of the receiving groove 8, and the slider 6 is slidably connected to the inside of the receiving groove 8.
[0029] The drying oven body 1 is provided with an adjusting rod 9 for rotating the mounting plate 5. The mounting plate 5 is rotatably connected to the outside of the adjusting rod 9. The drying oven body 1 is provided with a threaded groove 10, and the adjusting rod 9 is threadedly connected to the inside of the threaded groove 10.
[0030] A rotating shaft 11 is rotatably connected to the outside of the drying oven body 1. The mounting block 4 is fixedly connected to the outside of the rotating shaft 11. A storage groove 12 for storing the mounting block 4 is opened on the outside of the drying oven body 1. The rotating shaft 11 is rotatably connected to the inside of the storage groove 12.
[0031] The filter box 2 is provided with an isolation pad 13 for contacting the surface of the drying chamber 1 on the side near the drying chamber 1. An annular groove 14 is provided on the outside of the filter box 2, and the isolation pad 13 is snapped into the inside of the annular groove 14.
[0032] The control panel 15 is the interface for users to interact with the drying oven. Users can set parameters such as drying temperature, time, and ventilation rate through the control panel 15, and start, pause, or stop the drying process.
[0033] The main function of filter box 2 is to prevent dust and other impurities from entering the drying chamber through the vents;
[0034] The fixing frame 3 securely mounts the filter box 2 onto the drying chamber 1 by engaging with the mounting block 4, providing a reliable support structure for the filter box 2.
[0035] Mounting plate 5 is installed on the side of the drying chamber 1 near the operation panel 15. It is mainly used to provide a mounting position for the fixing frame 3 and to prevent the fixing frame 3 from shifting in the horizontal direction through the cooperation of the slider 6 on the mounting plate 5. At this time, the filter box 2 provides a cover for the operation panel 15.
[0036] The receiving groove 8 is opened on the outside of the mounting plate 5 to accommodate the helical spring 7 and the slider 6. It plays a certain guiding and limiting role in the movement of the helical spring 7 and the slider 6. The helical spring 7 is installed on the outside of the mounting plate 5 to provide elastic support for the slider 6, thereby ensuring the stability of the filter box 2 installation.
[0037] The adjusting rod 9 is used to rotate the mounting plate 5, thereby adjusting the position of the filter box 2 to meet different installation and usage requirements and improve the adaptability and flexibility of the equipment;
[0038] The threaded groove 10 is formed on the outside of the drying oven body 1 and is threadedly connected to the adjusting rod 9. The function of the threaded groove 10 is to provide a stable mounting base for the adjusting rod 9.
[0039] The storage slot 12 is located on the outside of the drying oven body 1 and is used to store the mounting block 4. The mounting block 4 can be stored in the storage slot 12 by rotating the pivot 11. It can also make the appearance of the equipment neater and more compact, and reduce the space occupied.
[0040] An annular groove 14 is formed on the outside of the filter box 2 to engage the isolation pad 13. The design of the annular groove 14 allows the isolation pad 13 to be fixed on the filter box 2, preventing it from shifting or falling off during use. The isolation pad 13 is mainly used to protect the surface of the drying oven body 1. During the installation and use of the filter box 2, the surface of the drying oven body 1 may be scratched or worn due to friction, vibration, etc. The isolation pad 13 is made of soft, wear-resistant and elastic materials, such as rubber and silicone, which can effectively buffer the friction and impact between the filter box 2 and the drying oven body 1, protect the surface coating and structural integrity of the drying oven body 1, and extend the service life of the drying oven.
[0041] Working principle:
[0042] First, when the drying oven is working, adjust the size of the vent and rotate the mounting block 4 upward to make it stand upright. At this time, the filter box 2 is attached to the outside of the mounting block 4 by the fixing bracket 3. The filter box 2 will block the vent. When the drying oven is not working, disconnect the mounting block 4 from the fixing bracket 3. Push the fixing bracket 3 to enter the storage slot 12. Rotate the mounting plate 5 to the appropriate position. Press the slider 6 to enter the receiving slot 8. The coil spring 7 is compressed. Slide the fixing bracket 3 to the outside of the mounting plate 5. When the fixing bracket 3 moves above the slider 6, release the slider 6. Continue to push the fixing bracket 3 until it passes the slider 6. The slider 6 will then return to its original position under the action of the coil spring 7. At this time, the filter box 2 will cover the control panel 15.
[0043] The second step is that when there is no need to cover the vent or the control panel 15, the filter box 2 can be placed directly on the workbench or connected to the mounting plate 5 as a temporary sample placement box.
[0044] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
