[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] See Figures 1-2 As shown, it includes a frame 1, on which a conveyor belt 2 driven by a main motor 3 is mounted. A tensioning mechanism 4 for adjusting the conveyor belt 2 is located on one side of the top of the frame 1. Guide roller 1 9 and guide roller 2 10 are also provided inside the frame 1, so that the conveyor belt 2 forms an inverted trapezoid. A cleaner 5 for cleaning the surface of the conveyor belt 2 and a disinfector 39 for disinfecting the surface of the conveyor belt 2 are provided in the frame 1. Guide roller 1 9 is located inside the cleaner 5. The conveyor belt 2 passes through the cleaner 5 and the disinfector 39 respectively. A gas cleaning mechanism is provided inside the cleaner 5. A filter exhaust mechanism for collecting debris and exhausting air is connected to the side of the cleaner 5.

[0020] See Figures 1-8 As shown, the gas cleaning mechanism includes a gas distribution pipe 12 located inside the cleaner 5. One end of the gas distribution pipe 12 is connected to a high-pressure air inlet pipe 11, which is connected to an external high-pressure gas supply device. The high-pressure gas is controlled by a gas valve, or a gas pulse is generated by a high-pressure pulse device to further enhance the cleaning ability. The cleaner 5 is equipped with several nozzles 14, all of which are angled upward toward the surface of the conveyor belt 2. The rear end of the nozzles 14 is connected to the gas distribution pipe 12 through a high-pressure hose 13. The cleaner 5 is equipped with an angle adjustment structure, which includes a reciprocating horizontal movement mechanism. All nozzles 14 are mounted on the reciprocating horizontal movement mechanism. The angle adjustment structure includes three rotating seats 22 located within the cleaner 5. Two bases 15 are connected to two rotating seats 22 via a pivot 21. The third rotating seat 22 is located in front of the middle of the two bases 15. The two bases 15 are connected to form an integral structure. A connecting plate 23 is connected to the upper front end of the two bases 15. A rotating seat 22 is also located below the connecting plate 23. An adjusting telescopic cylinder 24 is provided between the connecting plate 23 and the lower rotating seat 22. This cylinder is a servo electric cylinder to ensure adjustment accuracy. Both ends of the adjusting telescopic cylinder 24 are hinged. Figure 6 Taking the perspective as an example, by adjusting the extension and retraction of the telescopic cylinder 24, the distance between the front end of the base 15 and the bottom surface of the cleaner 5 can be changed, so that the base 15 rotates around the rotating shaft 21, which in turn drives the nozzle 14 to rotate, and adjusts the angle between the nozzle 14 and the surface of the conveyor belt 2 to adapt to the characteristics of food residue that may be generated by different materials of the conveyor belt 2 or different foods, so as to ensure the cleaning effect. The reciprocating transverse mechanism includes a linear guide rail 41 connected between two bases 15. The linear guide rail 41 is provided with multiple sliders, each slider is provided with a mounting seat 16, and the nozzles 14 are all mounted on the mounting seats 16. A drive block 17 is also provided between the two bases 15. The front end of each mounting seat 16 is connected to the drive block 17. Multiple slide rods 19 are connected between the two bases 15. Multiple drive sliders 18 are slidably mounted on the slide rods 19. The drive sliders 18 are all connected to the drive block 17. A reciprocating driver 25 is installed inside one of the bases 15. The drive sliders 18 are connected to the drive rods 20. The output end of the reciprocating driver 25 is connected to the drive rods 20. The reciprocating drive 25 includes a drive motor 26 located on the outside and a reciprocating screw assembly 28 located on the inside. A drive shaft 29 is slidably mounted in the reciprocating drive 25. The drive shaft 29 is connected to the drive rod 20 via a coupling 30. The rotating shaft 21 of the drive motor 26 is connected to the reciprocating drive 25 and is transmitted to the reciprocating screw assembly 28 via a gear set 27. The slider in the reciprocating screw assembly 28 is connected to the drive shaft 29.

[0021] The drive motor 26 drives the reciprocating screw assembly 28 through the gear set 27. Utilizing the characteristics of the reciprocating screw, the drive shaft 29 is driven to reciprocate. This, in turn, drives the drive slider 18 through the drive rod 20, which in turn drives the drive block 17, the mounting base 16, and the nozzles 14 to reciprocate. Multiple nozzles 14 reciprocate left and right, continuously spraying high-pressure airflow onto the surface of the conveyor belt 2 to prevent pressure dead zones from forming at the angles of the nozzles 14, which could lead to incomplete cleaning in certain areas and ensure effective cleaning.

[0022] See Figures 1-11 As shown, the filtration and exhaust mechanism includes an exhaust connection seat 6 connected to the side of the cleaner 5, which is through-hole, and the cleaner 5 has a corresponding air vent. A filter collector 32 is installed inside the exhaust connection seat 6. The internal size of the filter collector 32 is the same as the size of the air vent. Inclined grooves 35 are opened at both ends of the rear side of the filter collector 32 to facilitate entry. Several sieve holes are opened inside. Movable doors 31 are provided at both ends of the exhaust connection seat 6. The longitudinal cross-sectional size of the filter collector 32 corresponds to the size of the movable door 31. An air guide 7 is connected to the outside of the exhaust connection seat 6. An exhaust pipe 8 for discharging gas is connected to the air guide 7. Handles 33 are provided on the outside of the movable door 31 and at both ends of the filter collector 32. The filter collector 32 has an annular, protruding locking block 34 at its front edge, and a matching locking groove is opened at the outer edge of the air outlet. The locking block 34 is locked in the locking groove. A frame-shaped top block 36 is slidably provided at the edge of the through-hole inside the exhaust connection seat 6. Multiple sets of sliding grooves are opened inside the exhaust connection seat 6. Multiple sliding blocks 37 are connected to the top block 36. All sliding blocks 37 are slidably provided in the sliding grooves, and a spring 38 is provided behind the sliding block 37. The filter collector 32 can be installed using the exhaust connector 6. It can be quickly removed for replacement or installation from both ends. Taking installation as an example, the movable door 31 can be opened from the side to insert the filter collector 32 inward. Figure 4 and Figure 10 Taking the filter collector 32 as an example, when it enters, the inclined groove 35 contacts the top block 36, causing it to slide inward, pushing the sliding block 37 and compressing the spring 38. The locking block 34 will then press against the front of the filter collector 32 until the filter collector 32 is installed in place. Only then will the locking block 34 engage in the slot. At this point, the spring 38 will rebound, pushing the sliding block 37 and the top block 36 to press the filter collector 32 firmly against the wall. The top block 36 will also prevent gas leakage. Depending on actual needs, flexible sealing strips can be added to the front and sides of the top block 36 to ensure a seal. After the movable door 31 is closed, a second airtight seal can be formed. Therefore, in actual testing, if the seal of the top block 36 is insufficient, the movable door 31 can be equipped with a door latch or door lock for positioning. This structure is a supplementary setting, and the locking methods are all common mechanisms, which will not be described in detail in the instruction manual and attached drawings.

[0023] See Figures 1-12 As shown, several ultraviolet disinfection lamps 40 are installed at the bottom of the sterilizer 39 to sterilize the conveyor belt 2. The power of the ultraviolet disinfection lamps 40 is set according to the lower limit of the conveyor belt 2's transmission speed. Assuming the conveyor belt 2 runs at a speed of 0.05 m / s and the sterilization stroke is 50 cm, the exposure time is 10 s and the metering is 40 mJ / cm. 2 At this time, the sterilization effect is relatively strong, and the average illuminance is 4.0 mW / cm². 2 After increasing the margin, use 6.0mW / cm 2 Therefore, a 254nm low-pressure mercury lamp should be selected, and the irradiance should be measured on-site using a calibrated radiometer to ensure that the design value is met.

[0024] After the equipment starts operating, conveyor belt 2 begins to rotate. The conveyor belt 2 that has come into contact with food gradually enters the cleaner 5. High-pressure gas enters the air distribution pipe 12, is evenly distributed, and then sprays out from each nozzle 14 to clean the surface of conveyor belt 2. Figure 3From the perspective of the guide wheel 9, the conveyor belt 2 on its right side is inclined upwards. Therefore, the gas sprayed from the nozzle 14, mixed with food residue, is difficult to adhere to the rear conveyor belt. Instead, it flies out laterally and enters the filter collector 32. After passing through the sieve holes, the airflow is discharged through the exhaust pipe, preventing the gas from flowing out through the holes of the conveyor belt 2 due to the pressure difference inside and outside the cleaner 5. The debris is collected in the filter collector 32 and can be cleaned periodically. At the same time, the reciprocating drive 25 drives the nozzle 14 to move back and forth, further improving the cleaning quality. During this process, the guide wheel 9 maintains the shape of the conveyor belt 2 for easy cleaning and bears the pressure generated by the high-pressure gas on the surface of the conveyor belt 2 behind the conveyor belt 2, so as to reduce the situation where the conveyor belt 2 is stretched and deformed due to the suspended force. After cleaning, the conveyor belt 2 moves backward into the sterilizer 39 for ultraviolet disinfection to continuously ensure the cleanliness of the conveyor belt 2 and prevent floating bacteria or viruses from attaching or even multiplying, which would lead to a decline in hygiene.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be elaborated further.

Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention.
