DETAILED DESCRIPTION

[0040] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Embodiment 1

[0042] Figures 1 to 9An embodiment of the cleaning and sterilizing system of the filling component of the present invention is shown. The cleaning and sterilizing system of the filling component of this embodiment includes a filling component 1, an air shower chamber 2, and a sterilizing cup 3 detachably connected to the air shower chamber 2. The filling component 1 is provided with a filling needle seat 4 and a liquid inlet pipeline 11, the filling needle seat 4 is provided with a filling needle 5, the air shower chamber 2 is provided with an air inlet 27, the filling needle seat 4 is inserted into the air shower chamber 2 and a first inflatable sealing ring 21 is provided at the joint, and a second inflatable sealing ring 21 is provided between the air shower chamber 2 and the sterilizing cup 3. Sealing ring 37, the sterilization cup 3 is provided with an upper chamber 31, a lower chamber 32 and a needle filling channel 33 for the filling needle 5 to pass through, the upper chamber 31 and the lower chamber 32 are both connected to a discharge pipeline 6, and a temperature detection component 61 is provided on the discharge pipeline 6. The needle filling channel 33 is located between the upper chamber 31 and the lower chamber 32 and is provided with a third sealing member 34 for sealing the filling needle 5. The third sealing member 34 can be, for example, an ordinary sealing ring or a sealing gasket; the temperature detection component 61 can be, for example, a temperature sensor.

[0043] The cleaning and sterilization system of the filling component is that during filling, the sterilization cup 3 and the air shower chamber 2 are in a separated state, the first inflatable sealing ring 21 is deflated and contracted, thereby forming a gap between the sterilization cup 3 and the filling needle seat 4 to prevent the filling needle seat 4 from rubbing against the first inflatable sealing ring 21 to generate particles when the filling needle seat 4 is raised or lowered, and at the same time, a part of the Class A clean air entering from the air inlet 27 can flow out through the gap, and the other part can flow out from the bottom of the air shower chamber 2, thereby ensuring the cleanliness of the filling area; when cleaning and sterilization are required, the sterilization cup 3 is connected to the air shower chamber 2, the first inflatable sealing ring 21 and the second inflatable sealing ring 37 are inflated to ensure the static seal in the air shower chamber 2 and the sterilization cup 3, and a part of the steam flows out from the bottom of the air shower chamber 2. The steam is sterilized once through the liquid inlet pipe 11, the filling needle 5 and the lower chamber 32, and then discharged through the discharge pipe 6 connected to the lower chamber 32. Another part of the steam is sterilized through the air inlet 27, the air shower chamber 2 and the upper chamber 31 in turn, and then discharged through the discharge pipe 6 connected to the upper chamber 31. The filling needle 5 and the air shower chamber 2 can be sterilized online in all directions at the same time, which greatly reduces the risk of contamination. In addition, the temperature detection components 61 on the two discharge pipes 6 can respectively detect the temperatures of the steam discharged from the air shower chamber flow path (the flow path passing through the inside of the air shower chamber 2) and the filling needle flow path (the flow path passing through the inside of the filling needle 5), thereby ensuring that the sterilization effect of the filling needle 5 and the air shower chamber 2 is controllable.

[0044] Furthermore, in this embodiment, a diaphragm valve 62 is provided between the temperature detection component 61 and the sterilization cup 3. Before the cleaning and sterilization process, the diaphragm valve 62 can be closed to make the air shower chamber 2 and the interior of the sterilization cup 3 in a sealed environment.

[0045] Furthermore, in this embodiment, the first inflatable sealing ring 21 is connected to the first solenoid valve 22, and the second inflatable sealing ring 37 is connected to the second solenoid valve 35. The first solenoid valve 22 and the second solenoid valve 35 can be used to control the inflation and exhaust processes of the first inflatable sealing ring 21 and the second inflatable sealing ring 37, thereby improving the automation and intelligence of the system.

[0046] As a preferred embodiment, both the air shower chamber 2 and the sterilization cup 3 are provided with mounting grooves, the first inflatable sealing ring 21 is provided in the mounting groove of the air shower chamber 2, and the second inflatable sealing ring 37 is provided in the mounting groove of the sterilization cup 3, that is, the first inflatable sealing ring 21 is provided on the air shower chamber 2, and the second inflatable sealing ring 37 is provided on the sterilization cup 3, and the structure is simple and reasonable. Of course, in other embodiments, the first inflatable sealing ring 21 can also be provided on the needle filling seat 4, and the second inflatable sealing ring 37 can be provided on the air shower chamber 2. The disadvantage is that the first inflatable sealing ring 21 will move with the needle filling seat 4, resulting in the complicated filling and exhaust pipeline structure of the first inflatable sealing ring 21, and the second inflatable sealing ring 37 does not need to play a sealing role during the filling process, but will always be adversely affected by the high-temperature tube embryo extruded by the extruder.

[0047] Furthermore, in this embodiment, a guide member 23 is provided above the mounting groove of the air shower chamber 2 for guiding the needle holder 4. The guiding effect provided by the guide member 23 is conducive to ensuring that the needle holder 4 can move up and down smoothly and with high movement accuracy.

[0048] Furthermore, the air shower chamber 2 is provided with a pressure difference detection interface 24 and one or more sampling interfaces 25, which are convenient for detecting the air pressure in the air shower chamber 2 and sampling the cleaning liquid, steam, etc. in the air shower chamber 2 to ensure that the cleaning and sterilization effect is controllable.

[0049] Furthermore, in this embodiment, first hanging plates 26 are provided on both sides of the bottom of the air shower chamber 2, and second hanging plates 36 cooperating with the first hanging plates 26 are provided on both sides of the top of the sterilization cup 3. When the sterilization cup 3 needs to be connected to the air shower chamber 2, the sterilization cup 3 can be directly pushed horizontally into the bottom of the air shower chamber 2 so that the second hanging plates 36 and the first hanging plates 26 are mutually buckled, which has a simple structure and is easy to use.

[0050] Embodiment 2

[0051] The cleaning and sterilization method of the cleaning and sterilization system of the filling component of this embodiment includes a steam sterilization step.

[0052] The second inflatable sealing ring 37 is inflated to ensure the sealing between the sterilization cup 3 and the air shower chamber 2. The filling component 1 drives the filling needle 5 to descend and extend into the filling needle channel 33 and presses the third sealing member 34 to ensure the sealing between the filling needle 5 and the filling needle channel 33, so as to prevent the steam in the upper chamber 31 from entering the lower chamber 32 through the filling needle channel 33 and mixing with the steam in the lower chamber 32. Then the first inflatable sealing ring 21 is inflated to ensure the sealing between the filling needle seat 4 and the air shower chamber 2.

[0053] A part of the steam is sterilized through the liquid inlet pipe 11, the filling needle 5 and the lower chamber 32 in sequence (this part of the steam mainly sterilizes the inside of the filling needle 5 and the lower chamber 32 of the sterilization cup 3), and then discharged through the discharge pipe 6 connected to the lower chamber 32; another part of the steam is sterilized through the air inlet 27, the air shower chamber 2 and the upper chamber 31 in sequence (this part of the steam mainly sterilizes the inside of the air shower chamber 2, the outer wall of the filling needle 5 and the upper chamber 31 of the sterilization cup 3), and then discharged through the discharge pipe 6 connected to the upper chamber 31;

[0054] The temperature detection component 61 detects the temperature of the steam in the discharge pipe 6 .

[0055] This cleaning and sterilization method simultaneously performs all-round online sterilization on the filling needle 5 and the air shower chamber 2, greatly reducing the risk of contamination. The temperature of the steam discharged from the air shower chamber flow path and the filling needle flow path is detected by the temperature detection components 61 on the two discharge pipelines 6, respectively, ensuring that the sterilization effect of the filling needle 5 and the air shower chamber 2 is controllable.

[0056] In this embodiment, the specific steps of the cleaning and sterilization method are as follows:

[0057] S1.

[0058] A part of the cleaning liquid is cleaned through the liquid inlet pipe 11, the filling needle 5 and the lower chamber 32 in sequence, and then discharged through the discharge pipe 6 connected to the lower chamber 32; another part of the cleaning liquid is cleaned through the air inlet 27, the air shower chamber 2 and the upper chamber 31 in sequence, and then discharged through the discharge pipe 6 connected to the upper chamber 31;

[0059] The first inflatable sealing ring 21 and the second inflatable sealing ring 37 are exhausted, and the filling component 1 drives the filling needle 5 to rise and reset;

[0060] S2, steam sterilization;

[0061] S3, drying: a part of the clean gas is purged through the liquid inlet pipeline 11, the filling needle 5 and the lower chamber 32 in sequence, and then discharged through the discharge pipeline 6 connected to the lower chamber 32; another part of the clean gas is purged through the air inlet 27, the air shower chamber 2 and the upper chamber 31 in sequence, and then discharged through the discharge pipeline 6 connected to the upper chamber 31;
