[0026] Working principle:

[0027] During operation, the tunnel-type air shower and sterilization multi-functional machine conducts power-on self-check. After the self-check is error-free, the pneumatic door (11), the air suction and dust removal device (122), the air shower interval conveying device (13), the ultraviolet sterilization device (141), the ultraviolet sterilization device (21), the ultraviolet sterilization interval conveying device (22), and the liquid spraying sterilization interval conveying device (32) are all turned on. When the incoming materials arrive, the items directly enter the air shower and blowing dust removal interval (12). When the material triggers the conveying sensor (15) on the air shower interval conveying device (13), a signal is sent to the pneumatic door (11) to close it. At the same time, the blowing and dust removal device (121) is turned on for blowing, and the air shower interval conveying device (13) stops working. After the set blowing time has passed, the air shower interval conveying device (13) starts running, and at the same time, the blowing and dust removal device (121) stops working with a delay. The material will be transported to the transition sterilization interval (14) through the light-shielding curtain for preliminary sterilization. When the material is transported to the front-end trigger sensor on the ultraviolet sterilization interval conveying device (22), a signal is sent to the pneumatic door (11) to open it, and only then can the incoming materials enter. The previous incoming material air shower and blowing process is repeated; when the material is transported to the rear-end trigger sensor on the ultraviolet sterilization interval conveying device (22), this conveying device stops running, and static ultraviolet sterilization is carried out. After the set time has passed, this conveying device starts running, and this material will continue to be transported forward, leaving this ultraviolet sterilization chamber (2), and at the same time, the previous incoming materials will be transported to this section; the material is transported to the liquid spraying sterilization chamber (3). When the front-end sensor on the liquid spraying sterilization interval conveying device (32) is triggered, the liquid spraying sterilization device (31) is turned on for liquid spraying until it reaches the rear-end sensor on the liquid spraying sterilization interval conveying device (32). At the same time, a signal is sent to the pneumatic door at the equipment outlet, and the material completes the entire conveying process here.

[0028] Among them, the control system continuously provides support for the functions during the operation of the equipment. The filters inside the dust removal control system and the filtration control system are monitored by instruments such as differential pressure gauges to achieve the normal operation of the equipment functions. Similarly, the ultraviolet sterilization control system is also equipped with corresponding ultraviolet illuminance detection devices to continuously feedback the internal situation of the equipment working area. The exhaust control system works continuously or intermittently according to the actual usage conditions.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
