Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging machinery, in particular to a bottle washing device. Background Art

[0002] During transportation and sorting, plastic bottles will generate static electricity due to mutual squeezing and friction, and static electricity will absorb tiny particles, which may cause internal contamination of the bottle. If the particles are not processed and mixed into the liquid medicine, it will affect the composition of the liquid medicine and even affect the performance of the liquid medicine. Glass bottles are generally washed with water, then put into a tunnel oven for high-temperature drying and sterilization, and finally filled. However, plastic bottles are usually not resistant to high temperatures, so it is not appropriate to use the same cleaning and drying process as glass bottles. At present, airflow is generally used for purging. Although airflow purging can blow out the particles in the current bottle, the blown particles are uncontrolled and may enter the adjacent bottle, and the cleaning effect cannot be guaranteed.

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Figures 1 to 3 An embodiment of the bottle washing device of the utility model is shown. The bottle washing device of this embodiment includes a liftable air intake pipe 1. An exhaust pipe 2 is provided on the periphery of the air intake pipe 1. There is a gap between the inner wall of the exhaust pipe 2 and the outer wall of the air intake pipe 1. The air intake pipe 1 is connected to a first air intake component 3 and a second air intake component 4. The exhaust pipe 2 is connected to an exhaust component 5.

[0026] In the bottle washing device of this embodiment, after the bottle is transported to its place, the air inlet pipe 1 and the exhaust pipe 2 are lowered to dock with the bottle mouth, the first air inlet assembly 3 is purged by air intake and discharged through the exhaust assembly 5, and the air flow can be used to bring out the particles inside the bottle to achieve the purpose of cleaning. In addition, by using the air flow to wash the bottle, the bottle does not need to be sent to the drying equipment for drying after cleaning, and the cleaning is more convenient and efficient. Since the exhaust pipe 2 is sleeved on the outer periphery of the air inlet pipe 1, the air flow enters the bottle from the middle area of ​​the bottle and then is discharged from the four sides of the bottle, which is conducive to bringing out the particles in all directions inside the bottle, and at the same time, preventing the discharged particles from entering the adjacent bottle uncontrollably, thereby ensuring the cleaning effect. For the bottle that requires nitrogen filling before filling, the first air inlet assembly 3 and the exhaust assembly 5 can be closed after cleaning, and the second air inlet assembly 4 can be opened to fill the bottle with nitrogen to meet the process requirements. After cleaning and nitrogen filling are completed, the air inlet pipe 1 and the exhaust pipe 2 rise and reset to prepare for the next action.

[0027] Furthermore, in this embodiment, a conical guide portion 21 is provided at the lower end of the exhaust pipe 2. The conical guide portion 21 facilitates the exhaust pipe 2 to descend and accurately dock with the bottle mouth, and the structure is simple and effective.

[0028] Furthermore, in this embodiment, a sealing member 22 for sealing the bottle mouth is provided on the upper side of the conical guide portion 21, and the lower end of the air inlet pipe 1 passes through the sealing member 22 with a gap therebetween (i.e., there is a gap between the outer periphery of the air inlet pipe 1 and the inner hole of the sealing member 22 to facilitate the discharge of air). The bottle mouth is sealed by the sealing member 22 to prevent leakage. Preferably, the sealing member 22 is a sealing gasket, and as the exhaust pipe 2 descends, the sealing gasket is pressed against the bottle mouth, which is conducive to ensuring the sealing effect. Of course, in other embodiments, the sealing member 22 may also be an O-ring, a sealing strip, etc.

[0029] Furthermore, in this embodiment, the exhaust pipe 2 includes a first sleeve 23, a second sleeve 24 and an elastic buffer 25. The upper end of the first sleeve 23 extends into the second sleeve 24. A limiter 26 is provided in the second sleeve 24. The elastic buffer 25 is provided between the limiter 26 and the first sleeve 23. Correspondingly, the conical guide 21 and the seal 22 are provided at the lower end of the first sleeve 23. When the first sleeve 23 descends to contact the bottle body, the elastic buffer 25 can play a buffering role to avoid damage caused by rigid contact. At the same time, the elastic force of the elastic buffer 25 is also conducive to keeping the seal 22 in a compressed state to ensure sealing performance. The structure is reasonable and effective.

[0030] As a preferred embodiment, the elastic buffer 25 is a spiral spring, which has mature technology and good reliability. Of course, in other embodiments, the elastic buffer 25 can also be an elastic rope, an elastic rubber block, etc.

[0031] Furthermore, in this embodiment, the exhaust assembly 5 includes a vacuum pump 51. During cleaning, the vacuum pump 51 performs exhaust, which is beneficial for taking out particles inside the bottle body, further improving the cleaning effect.

[0032] Furthermore, in this embodiment, a check valve 52 is further provided between the vacuum pump 51 and the exhaust pipe 2. The check valve 52 can prevent external gas from flowing back into the bottle body, further improving the reliability of the device.

[0033] Furthermore, in this embodiment, the first air intake component 3 includes a first pressure gauge 31, an air source processing component 32 (for example, to dry the air, adjust the pressure, etc.) and a sterilizing filter 33 which are connected in sequence, and the sterilizing filter 33 is connected to the air intake pipe 1. During air intake cleaning, the first pressure gauge 31 can measure the air intake pressure, the air source processing component 32 processes the air intake, and the sterilizing filter 33 filters and sterilizes the air intake to ensure that the gas entering the bottle is clean and sterile. It should be noted that the first air intake component 3, the second air intake component 4 and the exhaust component 5 also include components such as a manual diaphragm valve 35 and / or a pneumatic diaphragm valve 36, so as to manually and / or automatically control the on and off of the first air intake component 3, the second air intake component 4 and the exhaust component 5.

[0034] Furthermore, in this embodiment, a flow meter 34 is further provided between the sterilizing filter 33 and the air inlet pipe 1. The flow meter 34 can detect the gas flow entering the air inlet pipe 1 to ensure the safe and stable operation of the bottle washing device. Preferably, the flow meter 34 is a rotor flow meter, which has a simple structure, small pressure loss, and is easy to disassemble and maintain.

[0035] Furthermore, in this embodiment, the second air intake assembly 4 includes a second pressure gauge 41 and a pressure regulating valve 42 which are connected in sequence, and the pressure regulating valve 42 is connected to the sterilizing filter 33. When nitrogen is charged, the second pressure gauge 41 can measure the intake pressure of nitrogen, and the pressure regulating valve 42 can adjust the intake pressure of nitrogen to meet the requirements of the nitrogen charging process, and the structure is simple and effective.
