[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figures 2 - 4, an embodiment provided by the present utility model: a high-wind-pressure insect-proof air curtain machine for a food processing factory, including a housing 1, an installation frame 2 is fixedly connected to the inner top of the housing 1, a double-headed motor 3 is fixedly connected inside the installation frame 2, a rotating shaft 4 is fixedly connected to the output end of the double-headed motor 3, a wind wheel 5 is fixedly connected to the end of the rotating shaft 4 away from the double-headed motor 3, an air outlet 6 is opened in the middle of the lower part of the housing 1, a guide vane 7 is rotatably connected inside the air outlet 6, an air outlet sleeve 18 is fixedly connected to the lower part of the housing 1, and the air outlet sleeve 18 is located outside the lower part of the air outlet 6. An insect-proof component is arranged inside the front side of the housing 1 for dust-proofing the air curtain machine. The insect-proof component includes a mounting plate 9, the mounting plate 9 is slidably connected to the left and right sides inside the housing 1, an insect-proof plate 10 is fixedly connected to the front side of the mounting plate 9, and a plurality of air inlets 11 are evenly opened on the left and right sides in the middle of the insect-proof plate 10. Installation rods 13 are slidably connected to the upper and lower parts of the left and right sides inside the housing 1. A spring 14 is arranged outside the opposite sides of the installation rods 13. A connecting plate 16 is fixedly connected to the opposite ends of the installation rods 13. Limiting shafts 17 are fixedly connected to the upper and lower parts of the opposite sides of the connecting plate 16. A handle two 15 is fixedly connected to the end of the installation rod 13 away from each other. The connecting plate 16 is slidably connected to the left and right sides inside the housing 1. The limiting shaft 17 is slidably connected to the inner side of the mounting plate 9. One end of the spring 14 is fixedly connected to the housing 1, and the other end of the spring 14 is fixedly connected to the connecting plate 16. A handle one 12 is fixedly connected to the middle of the front side of the insect-proof plate 10.

[0031] By pulling the handle two 15, the handle two 15 drives the installation rod 13 to move. The movement of the installation rod 13 further pushes the connecting plate 16 to move along a predetermined track. During this process, the connecting plate 16 compresses the spring 14, causing the spring 14 to be subjected to a compressive force. As the connecting plate 16 continues to move, the limiting shaft 17 also moves accordingly, and finally the limiting shaft 17 disengages from the fixed position on the mounting plate 9. When the limiting shaft 17 disengages from the mounting plate 9, the operator can pull the handle one 12. The action of pulling the handle one 12 causes the handle one 12 to drive the insect-proof plate 10 to move. The movement of the insect-proof plate 10 will cause it to come into contact with the mounting plate 9, thereby pushing the mounting plate 9 to slide along its slide rail. As the insect-proof plate 10 continues to move, the mounting plate 9 will finally disengage from the housing 1. This series of actions ensures the smooth separation of the insect-proof plate 10 and the mounting plate 9, enabling the structures or components inside the housing 1 to be properly adjusted, maintained, or replaced. The movement of each component is precisely designed to ensure the smooth operation of the operation and the reliability of the system.

[0032] Refer to Figures 1 - 3, an installation component is provided at the rear side of the housing 1 for installing the air curtain machine. The installation component includes a connecting frame 8. Connecting blocks 19 are evenly and fixedly connected to the periphery of the rear side of the connecting frame 8. A first bolt 20 is threadedly connected to the middle of the connecting block 19. A fixing plate 21 is slidably connected to the opposite sides of the left and right connecting blocks 19. Fixing blocks 22 are fixedly connected to the middle parts of the left and right sides of the fixing plate 21. A number of second bolts 23 are evenly and threadedly connected to the middle of the fixing block 22. The connecting block 19 is connected to the fixing plate 21 through the first bolt 20, and the fixing block 22 is connected to the installation wall through the second bolt 23.

[0033] By pushing the housing 1, the movement of the housing 1 will drive the corresponding movement of the connecting frame 8. During the movement of the connecting frame 8, the fixing plate 21 will be moved to the front position of the installation wall. At this time, the operator can rotate the second bolt 23 and tighten it, so that the second bolt 23 firmly connects the fixing block 22 to the installation wall, thereby fixing the position of the air curtain machine and ensuring the stability of the equipment. When it is necessary to repair the air curtain machine, first, the fixation needs to be released. For this purpose, the operator should rotate the first bolt 20 to release the connection between the first bolt 20 and the connecting block 19. In this way, the connection between the connecting block 19 and the fixing plate 21 will be loosened. Next, pull the housing 1 to continue driving the connecting frame 8 to move. The movement of the connecting frame 8 will cause the connecting block 19 to slide relatively, so as to disengage it from the fixing plate 21. In this way, the air curtain machine can be smoothly moved away or necessary repair operations can be carried out without completely disassembling other components. This design ensures that the maintenance process of the air curtain machine is both efficient and convenient.

[0034] Working principle: When it is necessary to disassemble the insect-proof board 10, pull the second handle 15 so that the second handle 15 drives the installation rod 13 to move. The installation rod 13 drives the connecting plate 16 to move and compress the spring 14. The connecting plate 16 drives the limit shaft 17 to move out of the installation plate 9. Finally, pull the first handle 12 so that the first handle 12 drives the insect-proof board 10 to move. The insect-proof board 10 drives the installation plate 9 to slide out of the housing 1. In this way, it is realized that the insect-proof air curtain machine is convenient for installing and disassembling the insect-proof board 10, and the cleaning difficulty of the insect-proof board 10 is reduced. When it is necessary to install the air curtain machine, push the housing 1 so that the housing 1 drives the connecting frame 8 to move. The connecting frame 8 drives the fixing plate 21 to move to the front of the installation wall, and then rotate the second bolt 23 to connect the fixing block 22 and the installation wall. When it is necessary to repair the air curtain machine, rotate the first bolt 20 to make the first bolt 20 disengage from the connecting block 19 and the fixing plate 21, and pull the housing 1 so that the housing 1 drives the connecting frame 8 to move. The connecting frame 8 drives the connecting block 19 to slide out of the fixing plate 21. In this way, it is realized that the insect-proof air curtain machine is convenient for installing and disassembling, and the maintenance difficulty of the air curtain machine is reduced.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
