[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: a spray sterilization device, including two symmetrically arranged support plates 1, and a conveyor belt 4 is arranged between the two support plates 1.

[0028] A drive roller is installed at one end of the conveyor belt 4, and a drive roller is installed at the other end. A motor 2 is fixedly connected to one side of one of the support plates 1, and the motor 2 drives the drive roller to rotate. The rotation of the drive roller moves the conveyor belt 4, causing the drive roller to rotate. A rotating roller 3 is rotatably installed in the middle of the conveyor belt 4. The drive roller and the rotating roller 3 are driven by a first chain. When the drive roller rotates, it drives the rotating roller 3 to rotate via the first chain.

[0029] A work box 9 is fixedly installed directly above the middle of the conveyor belt 4. Support plates are fixedly connected to the top of the two support plates 1, and the top of the two support plates are fixedly connected to the bottom of the work box 9. The work box 9 is supported and fixed by the support plates.

[0030] Two sets of cleaning components are symmetrically arranged at the bottom of the working box 9. Each set of cleaning components includes several spaced-apart brush rods 12, the top of which is rotatably connected to the bottom of the working box 9. The brush rods 12 are connected to the working box 9 by bearings, which increase the stability of the brush rods 12.

[0031] Several positioning components are fixedly installed at intervals on the outer surface of the conveyor belt 4. Several brush rods 12 of each cleaning component are arranged in a straight line, and the positioning components are located between two cleaning components. The bottles are fixed by the positioning components, allowing the bottles to move between the two cleaning components so that the bottles can be cleaned by the cleaning components.

[0032] The positioning assembly includes a placement plate 5, which is fixedly connected to the conveyor belt 4. Two symmetrical grooves are formed on the inner wall of the placement plate 5, and two springs 6 are symmetrically fixedly connected inside each groove. The other ends of the two springs 6 are fixedly connected to the same fixing plate 7. When the springs 6 are in their natural state, the fixing plate 7 extends outside the groove. When the bottom of a bottle is placed into the placement plate 5, the bottle presses against the fixing plate 7, and the bottle is secured by the elastic force of the springs 6. The tops of the adjacent sides of the two fixing plates 7 are inclined. The inclined surfaces facilitate the placement of bottles between the two fixing plates 7.

[0033] Two drive components are symmetrically arranged on the working box 9, with each drive component corresponding to a cleaning component. The drive components drive several brush rods 12 on the corresponding cleaning components to rotate synchronously.

[0034] The drive assembly includes a connecting rod 10 that rotatably extends through the side of the work box 9. A bearing is installed at the connection point between the connecting rod 10 and the work box 9 to facilitate rotation and increase stability. One end of the connecting rod 10 extending outside the work box 9 is connected to a rotating roller 3 via a belt 8, and the other end of the connecting rod 10 is fixedly connected to a first bevel gear 11. When the rotating roller 3 rotates, it drives the connecting rod 10 to rotate via the belt 8, which in turn drives the first bevel gear 11 to rotate.

[0035] The tip of one of the brush rods 12 in each cleaning assembly rotates through the bottom surface of the work box 9, and the tips of the two brush rods 12 extending into the work box 9 are fixedly connected to a second bevel gear 13. The second bevel gear 13 meshes with the corresponding first bevel gear 11. Rotation of the first bevel gear 11 drives the second bevel gear 13 to rotate, causing the corresponding brush rod 12 to rotate.

[0036] Each brush handle 12 is fixedly fitted with a sprocket at its top, and a second chain 14 is driven onto several sprockets on each cleaning assembly. Through the cooperation of the second chain 14 and the sprockets, the corresponding brush handles 12 rotate together.

[0037] A connecting frame 20 is fixedly connected inside the working box 9. An air bladder 21 is disposed inside the connecting frame 20, and the end of the air bladder 21 is fixedly connected to the inner wall of the connecting frame 20. A disinfectant tank 24 is connected to the top of the air bladder 21. The disinfectant tank 24 is filled with disinfectant to sterilize the bottles. A spray box 25 is connected to the bottom of the air bladder 21, and a squeezing plate 19 is fixedly connected to one end of the air bladder 21. The squeezing plate 19 is slidably connected inside the connecting frame 20.

[0038] The disinfectant tank 24 is fixedly connected to the top of the working chamber 9. A second connecting pipe 23 is fixedly connected to the outlet at the bottom of the disinfectant tank 24. The second connecting pipe 23 passes through the top surface of the working chamber 9, and its bottom end is fixedly connected to the top of the air bladder 21. This allows the disinfectant in the disinfectant tank 24 to enter the interior of the air bladder 21 through the second connecting pipe 23. A second one-way valve is provided on the second connecting pipe 23, which allows the disinfectant in the disinfectant tank 24 to flow into the interior of the air bladder 21.

[0039] The spray box 25 is fixedly connected to the bottom of the working box 9. A first connecting pipe 22 is fixedly connected to the inlet at the top of the spray box 25. The first connecting pipe 22 passes through the bottom surface of the working box 9, and the top end of the first connecting pipe 22 is fixedly connected to the bottom of the airbag 21. This allows the disinfectant in the airbag 21 to enter the interior of the spray box 25 through the first connecting pipe 22. A first one-way valve is provided on the first connecting pipe 22, which allows the disinfectant in the airbag 21 to flow into the interior of the spray box 25. Several spray nozzles are evenly fixedly connected to the bottom of the spray box 25.

[0040] The working box 9 is equipped with a transmission component, which works in conjunction with the drive component. When the brush rod 12 rotates, the transmission component drives the extrusion plate 19 to slide back and forth inside the working box 9.

[0041] The transmission assembly includes a disc 15, which is coaxially and fixedly connected to one end of a connecting rod 10 away from the belt 8. A connecting shaft is eccentrically and fixedly connected to one side of the disc 15. The connecting rod 10 drives the disc 15 to rotate, causing the connecting shaft to rotate around the axis of rotation of the disc 15.

[0042] A limiting plate 17 is fixedly connected inside the working box 9, and a connecting plate 18 slides horizontally through the limiting plate 17. The connecting plate 18 has a rectangular cross-section, allowing it to slide only on the limiting plate 17. One end of the connecting plate 18 is fixedly connected to one side of the extrusion plate 19, and the other end of the connecting plate 18 is rotatably connected to a connecting rod 16, the other end of which is rotatably sleeved on a connecting shaft. When the connecting shaft rotates with the disc 15, it pushes the connecting plate 18 to slide via the connecting rod 16.

[0043] Working principle:

[0044] When in use, push the bottom of the bottle between the two fixed plates 7 so that the bottom of the bottle is inside the placement plate 5 until the bottom of the bottle contacts the conveyor belt 4.

[0045] When the bottle is pushed in, it presses against the two fixing plates 7, causing the fixing plates 7 to slide into the groove and compress the spring 6. The spring 6 exerts a pushing force on the fixing plates 7, causing the fixing plates 7 to abut against the outer surface of the bottle. Therefore, the bottle is fixed between the two fixing plates 7 under the action of the spring 6.

[0046] Start motor 2, which drives the drive roller in conveyor belt 4 to rotate, causing conveyor belt 4 to move. The drive roller rotates, driving the placement plate 5 and the bottles to move. At the same time, the drive roller drives the rotating roller 3 to rotate via the first chain.

[0047] The rotating roller 3 drives the two connecting rods 10 to rotate via belts 8 at both ends, causing the first bevel gear 11 to rotate. The first bevel gear 11 drives the corresponding second bevel gear 13 to rotate, causing the corresponding brush rod 12 to rotate.

[0048] The rotation of the sprocket on the brush handle 12 drives several corresponding brush handles 12 to rotate together via the second chain 14. As the brush handles 12 rotate, they clean the outer surface of the bottle that has moved to the bottom of the work box 9.

[0049] When one of the connecting rods 10 rotates, it drives the disk 15 to rotate, causing the connecting shaft to rotate around the axis of rotation of the disk 15. The connecting shaft drives one end of the connecting rod 16 to move, and the other end of the connecting rod 16 pulls the connecting plate 18 to slide back and forth on the limiting plate 17. The limiting plate 17 drives the compression plate 19 to slide back and forth inside the connecting frame 20, and the compression plate 19 pushes one end of the airbag 21.

[0050] When the extrusion plate 19 moves toward the end closer to the limiting plate 17, the airbag 21 generates suction, causing the disinfectant in the disinfectant tank 24 to enter the interior of the airbag 21 through the second connecting pipe 23.

[0051] When the squeezing plate 19 moves away from the limiting plate 17, the airbag 21 is squeezed, and the disinfectant inside the airbag 21 enters the spray box 25 through the first connecting pipe 22. It is then sprayed onto the bottle at the bottom through the nozzle, thus sterilizing the bottle through spraying.

[0052] After being sprayed, the bottle moves to the end of conveyor belt 4, where workers pull the bottle upwards to move it between the two fixing plates 7. Then, spring 6 pushes the fixing plates 7 closer together to secure the bottle again.

[0053] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
