Description

Technical Field

[0001] This invention relates to a cleaning and drying device, specifically a device for cleaning and drying the outer wall of a bottle. Background Technology

[0002] In the pharmaceutical industry's glass bottle oral liquid production workshop, after completing the filling and sealing process, two important subsequent processes are light inspection and labeling. These two processes are crucial to product quality. Occasionally, during the filling process, some liquid medicine (containing syrup) may spill and adhere to the glass bottle wall. This syrup residue can cause false detection by the light inspection machine, and the labeling machine may fail to apply labels properly or apply them incorrectly.

[0003] The bottle washing and drying machine disclosed in CN201220007042.4 is a device for cleaning and drying medicine bottles after liquid filling. It cleans and dries the bottles through a rinsing chamber, a cold air chamber and a hot air chamber. However, since the bottles pass through the hot air chamber after cleaning and drying, the temperature of the bottles is high when they are transported out. They need to be cooled before the next process can be carried out, which takes a long time. Summary of the Invention

[0004] The technical problem to be solved by this invention is the high temperature of the bottle after it has been cleaned and dried.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a bottle outer wall cleaning and drying device is provided, characterized in that it includes a horizontally transporting conveyor, and a cleaning device, a first cold air zone, a hot air zone, and a second cold air zone arranged sequentially along the transport direction of the conveyor. The first cold air zone is located above the conveyor and has a plurality of evenly distributed first cold air components. The hot air zone is located above the conveyor and has a hot air component. The second cold air zone is located above the conveyor and has a plurality of evenly distributed second cold air components. The conveyor includes a horizontally transporting conveyor belt, and the conveyor belt has at least one smoothly transitioning ridge along its transport plane at the positions corresponding to the cleaning device, the first cold air component, the hot air component, and the second cold air component.

[0007] Furthermore, sprockets are installed at the corresponding raised positions of the conveyor belt. The sprockets are used to support the conveyor belt so that the conveyor belt in contact with the sprockets is higher than the horizontal transport plane of the conveyor belt, so that the bottles may temporarily separate from the surrounding bottles during the transport process.

[0008] Furthermore, the sprocket engages with the conveyor belt to drive the conveyor belt to move, ensuring that the conveyor belt smoothly transports the bottles.

[0009] Furthermore, the conveying device is equipped with a water tank corresponding to the cleaning device for storing cleaning liquid. A water pump is installed on the water tank for transporting the cleaning liquid in the water tank to the cleaning device. A heating component is installed in the water tank for heating the cleaning liquid in the water tank. By heating the cleaning liquid, the cleaning effect can be effectively improved.

[0010] Furthermore, the cleaning device includes several nozzles that are evenly distributed along the conveying direction of the conveying device. Through multiple nozzles, the bottles during the conveying process can be effectively cleaned, ensuring that each bottle is effectively cleaned.

[0011] Furthermore, a fan is provided below the conveying device, and the fan is connected to the first cold air assembly and the second cold air assembly to provide cold air to the first cold air zone and the second cold air zone. A hot air fan is provided below the conveying device, and the hot air fan is connected to the hot air assembly to provide hot air to the hot air zone. The first cold air zone, the hot air zone and the second cold air zone are all covered with protective covers.

[0012] Furthermore, both the first and second cold air components include a housing, the housing having an air inlet channel and an air outlet, and the housing having several layers of filters disposed inside the air outlet.

[0013] Furthermore, two adjusting plates distributed in an inverted cone shape are provided on the inner side of the air outlet. The near ends of the adjusting plates are close to the air outlet and there is a gap for airflow to pass through. Several through bolts are provided on the side of the outer shell at the position corresponding to the adjusting plates, for adjusting the gap between the near ends of the two adjusting plates.

[0014] Furthermore, a nut is fixedly installed at the position of the corresponding bolt on the outer shell, the bolt and the nut are threadedly connected, and the inner end of the bolt is in contact with the side of the corresponding adjusting piece.

[0015] Furthermore, a pivot is installed on the housing for adjusting the orientation of the air outlet.

[0016] This invention offers the following advantages: It uses a cleaning device to remove residual medication from the bottle exterior. A first cold air cycle removes most of the cleaning liquid, followed by a hot air zone to dry the remaining liquid on the bottle wall. Finally, a second cold air zone removes excess heat from the bottle. This eliminates the need to wait for the bottle to cool down before labeling, improving work efficiency. Furthermore, raised sections on the conveyor belt ensure that bottles do not come into contact with other bottles during transport, enhancing the cleaning and drying effect and improving work quality. The device is also highly adaptable; it can be used even after changing bottle sizes, and the smooth bottle movement prevents breakage, saving production costs. Attached Figure Description

[0027] This invention provides a bottle outer wall cleaning and drying device, such as... Figure 1 As shown, it includes a conveying device 10, which is used to transport bottles to be cleaned and dried. A cleaning device 11, a first cold air zone 20, a hot air zone 30 and a second cold air zone 40 are arranged sequentially above the conveying device 10 along its conveying direction.

[0028] Specifically, when the conveying device 10 transports the bottles, the bottles first pass through the cleaning device 11, which cleans the outer wall of the bottles. After cleaning, the outer wall of the bottles is covered with a lot of cleaning liquid and first enters the first cold air zone 20. The first cold air zone 20 is equipped with a first cold air assembly 21, which blows cold air onto the bottles. After passing through the first cold air zone 20, the bottles enter the hot air zone 30, which is equipped with a hot air assembly 31, which blows hot air onto the bottles. After passing through the hot air zone 30, the bottles enter the second cold air zone 40, which is equipped with a second cold air assembly 41, which blows cold air onto the bottles. After passing through the second cold air zone 40, the bottles can be processed further.

[0029] Specifically, in this embodiment, the first cold air assembly 21, the hot air assembly 31, and the second cold air assembly 41 are located above the conveying device 10, so that both cold and hot air are blown onto the bottle from top to bottom. After the bottle passes through the cleaning device 11, a lot of cleaning liquid adheres to the bottle. At this time, the first cold air assembly 21 blows cold air onto the bottle, which can blow away the large amount of cleaning liquid adhering to the bottle. Generally, only a thin layer of cleaning liquid adheres to the bottle after passing through the first cold air zone 20. When passing through the hot air zone 30, the hot air assembly 31 blows hot air onto the bottle. Under the action of the hot air, the thin layer of cleaning liquid on the bottle can be dried. The bottle has been dried after passing through the hot air zone 30, but the temperature of the bottle is still high. Then, after passing through the second cold air zone 40, the second cold air assembly 41 blows cold air onto the bottle, which can blow away the heat on the bottle, thereby achieving rapid cooling of the bottle. Therefore, the bottle can be processed later without waiting, improving work efficiency.

[0030] like Figure 1 and Figure 2 As shown, when bottles are transported on the conveyor device 10, the bottles may stick together tightly, causing the areas where the bottles are stuck to the conveyor to not be completely covered by the cold or hot air. This results in poor drying and cleaning of the liquid and leaves residual cleaning liquid. To overcome this problem, the conveyor device 10 includes a conveyor belt 14 that transports bottles horizontally. At least one protrusion is provided at the positions corresponding to the cleaning device 10, the first cold air assembly 21, the hot air assembly 31, and the second cold air assembly 41. A sprocket 15 is installed at each of the protrusions. The sprocket 15 supports the conveyor belt 14, making it protruding at the position of the sprocket 15. The part of the conveyor belt 14 in contact with the sprocket 15 is higher than the other parts of the conveyor belt 14. The conveyor belt 14 also transitions smoothly at the position of the sprocket 15, ensuring that the bottles pass smoothly through the sprocket 15.

[0031] like Figure 2As shown, when the bottle is conveyed by the conveyor belt 14 through the sprocket 15, the bottle essentially goes through an "uphill" and a "downhill" process. Specifically, as the bottle moves from the horizontally conveying conveyor belt 14 to the sprocket 15, it goes uphill, gradually tilting to the left until it reaches the highest point of the ridge. At this point, it goes downhill, tilting to the right. During this left-to-right tilting process, the bottle reaches a vertical position, where it is not in contact with its surrounding body. Specifically, when the bottle moves to the highest point of the bulge, it changes from tilting to the left to a vertical position, and then from a vertical position to tilting to the right. The bottle in the vertical position is to the left of the bottle tilting to the left, and to the right of the bottle tilting to the right. Therefore, the vertical bottle will not come into contact with the bottles next to it, ensuring that the cold or hot air blowing from top to bottom can more effectively blow away and dry the cleaning liquid on the bottle, and also smoothly remove the heat from the bottle. Correspondingly, the bottle at the cleaning device 10 can also come into more full contact with the cleaning liquid, ensuring that the bottle is cleaned thoroughly and improving the quality of work.

[0032] Since the sprocket 15 lifts the conveyor belt 14 upwards, it can also tighten the conveyor belt 14. At the same time, the sprocket 14 meshes with the conveyor belt 14, and by driving the sprocket 5 to rotate, it can also drive the conveyor belt 14 to move synchronously.

[0033] To improve drying efficiency, multiple first cold air components 21 and second cold air components 41 are provided, and they are distributed at equal distances along the conveying direction of the conveying device 10.

[0034] In this embodiment, as Figure 1 As shown, a water tank 12 is installed below the transport device 10. The water tank 12 contains cleaning liquid for cleaning the bottle body. To save costs, clean water is selected as the cleaning liquid. A water pump 13 is installed on the water tank 12. The water pump 13 introduces clean water into the cleaning device 11. The cleaning device 11 is located above the transport device 10. In order for the cleaning device 11 to clean the bottle body, the cleaning device 11 includes several nozzles. The nozzles are evenly distributed along the transport direction of the transport device 10. The nozzles spray the clean water guided by the water pump 13 onto the bottle body to clean it. After being cleaned with clean water, the bottle enters the first cold air zone 20. A heating component is installed on the corresponding water tank 12 to heat the clean water contained in the water tank 12. The heated clean water is sprayed onto the bottle body through the nozzles.

[0035] like Figure 1As shown, a fan 50 is provided below the conveying device 10. The fan 50 is connected to the first cold air assembly 21 and the second cold air assembly 41 to provide them with cold air. In this embodiment, two fans 50 can be selected, one fan 50 is connected to the first cold air assembly 21 and the other fan 50 is connected to the second cold air assembly 41. Correspondingly, a hot air blower 32 is also provided below the conveying device 10. The hot air blower 32 is connected to the hot air assembly 31 to provide hot air to the hot air assembly 31.

[0036] like Figure 3 As shown, in order to adjust the amount of cold air blown out by the first cold air assembly 21 and the second cold air assembly 41, both the first cold air assembly 21 and the second cold air assembly 41 include a housing 22. The housing 22 is provided with an air inlet channel 23 and an air outlet 24. The air inlet channel 23 is connected to the fan 50, and the air outlet 24 blows out the air. The housing 22 is provided with multiple layers of filter screens 25. In this embodiment, two layers of filter screens 25 are selected. Through the filter screens 25, solid particles in the airflow introduced into the air inlet channel 23 by the fan 50 can be filtered out, preventing solid particles from hitting the bottle body through the airflow and causing damage to the bottle body, thereby improving the safety of the device.

[0037] Specifically, to adjust the size of the cold air blown out, two adjusting plates 27 arranged in an inverted cone shape are provided on the inner side of the air outlet 24. In this embodiment, the lower part of the two adjusting plates 27 is the near end, which is close to the air outlet 24. There is a gap between the two adjusting plates 27 at the near end for airflow to pass through. Adjusting the size of the gap between the two adjusting plates 27 at the near end changes the size of the airflow blown out of the air outlet 24. Several through bolts 29 are provided on the side of the outer shell 22 corresponding to the position of one of the adjusting plates 27. Nuts 26 are fixedly installed on the outer shell 22 at the positions corresponding to the bolts 29. The bolts 29 are threadedly connected to the corresponding nuts 26. The end of the bolt 29 that extends into the inner part of the outer shell 22 contacts the side of the corresponding adjusting plate 27. When the bolt 29 is turned, the bolt 29 pushes the adjusting plate 27 to move closer to the near end of the other adjusting plate 27, thereby changing the distance between the near ends of the two adjusting plates 27 and realizing the change of the airflow size.

[0038] Specifically, in this embodiment, the far ends of the two adjusting plates 27 can be fixedly installed on the inner wall of the outer casing 22, and the adjusting plates 27 have a certain elasticity. When the bolt 29 is turned, the bolt 29 pushes the adjacent ends of the adjusting plates 27 closer together, reducing the size of the gap. When the bolt 29 is turned in the opposite direction, the adjusting plates 27 return to their original state, thereby increasing the size of the gap. The size of the cold air blown out can be adjusted by turning the bolt 29.

[0039] like Figure 4As shown, in this embodiment, a rotating shaft 28 is installed on the outer casing 22, and an air outlet 24 is opened at the bottom of the outer casing 22. The outer casing 22 can be rotated by the rotating shaft 28 so that the air outlet 24 faces different directions.

[0040] To protect this equipment, such as Figure 5 As shown, the first cold air zone 20, the hot air zone 30, and the second cold air zone 40 are all covered with an outer cover 60.

However, the present invention is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of the present invention should be covered within the protection scope of the present invention.
