Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention. In addition, the embodiments of the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0034] See also Figure 1-4As shown, this embodiment provides a dispenser, including a turntable 1 that can rotate around its own axial centerline, a rotating shaft 2 coaxially connected to one side of the turntable 1, a shell 3 coaxially sleeved on the outside of the rotating shaft 2, and a first sealing ring 4 ringed between the rotating shaft 2 and the shell 3. The rotating shaft 2 is provided with at least one medium channel 21 whose two ends are respectively connected to the turntable 1 and the shell 3. The turntable 1 is used to connect to the rotating body of the filling equipment to perform synchronous rotation.

[0035] In this embodiment, the rotating shaft 2 is parallel to the vertical direction, and there are multiple first sealing rings 4 that are arranged at intervals along the vertical direction; two groups of bearings 17 are also provided between the rotating shaft 2 and the housing 3, and the two groups of bearings 17 are respectively located at the upper end and the lower end of the rotating shaft 2.

[0036] The distributor further comprises a mounting seat 5, a moving bracket 6 disposed on the mounting seat 5 and capable of reciprocating movement in a first direction, a first pipe 7 disposed on the housing 3 and connected to the medium channel 21, a second pipe 8 disposed on the moving bracket 6, and an anti-rotation mechanism. In this embodiment, the first direction is parallel to the rotating shaft 2, the housing 3, the moving bracket 6 and the mounting seat 5 are respectively located on the same side of the rotating disk 1, and the three are arranged in sequence along the first direction; the distributor further comprises a driving member 16 disposed on the mounting seat 5, and the driving member 16 is used to drive the moving bracket 6 to reciprocate in the first direction.

[0037] The above-mentioned moving bracket 6 can approach or move away from the housing 3 along the first direction, and the moving bracket 6 has a first position and a second position relative to the housing 3:

[0038] See also Figure 3-4 As shown, when the moving bracket 6 is in the first position relative to the housing 3, the second pipe 8 is connected to the first pipe 7, and the anti-rotation mechanism is used to abut the housing 3 to prevent it from rotating with the rotating shaft 2;

[0039] See also Figure 1-2 As shown, when the moving bracket 6 is in the second position relative to the housing 3 , the second pipe 8 and the first pipe 7 are disengaged, the anti-rotation mechanism is disengaged from the housing 3 , and the housing 3 can rotate along with the rotating shaft 2 .

[0040] The housing 3 includes a cylindrical body 31 sleeved on the outside of the rotating shaft 2, a first stopper 32 provided on the outer peripheral portion of the cylindrical body 31, and the anti-rotation mechanism includes a second stopper 9 provided on the moving bracket 6. One of the first stopper 32 and the second stopper 9 is provided with a groove 91, and the other is used to be inserted into the groove 91 when the moving bracket 6 is in the first position relative to the housing 3.

[0041] In this embodiment, the first stopper 32 is radially and outwardly disposed on the outer peripheral portion of the cylindrical body 31, and the second stopper 9 is provided with a groove 91 opening upward, and the arrangement direction of the groove walls on both sides of the groove 91 is perpendicular to the center line of the rotating shaft 2 of the rotating shaft 2. Through this arrangement, when the first stopper 32 extends into the groove 91, the cylindrical body 31 can be limited to prevent it from rotating with the rotating shaft 2.

[0042] In this embodiment, the distance between the groove walls on both sides of the groove 91 gradually increases in the upward direction, so as to guide the entry of the first limiting member 32 .

[0043] See also Figure 5 As shown, the first pipe 7 includes a first pipe opening 71, the second pipe 8 includes a second pipe opening 81 for sleeved with the first pipe opening 71, and a guide portion 82 formed by the outer end of the second pipe opening 81 gradually opening in the direction toward the first pipe opening 71. By providing the trumpet-shaped guide portion 82, a guiding effect can be played on the mutual insertion of the first pipe opening 71 and the second pipe opening 81.

[0044] In this embodiment, a second sealing ring 12 is disposed around the outer side of the first pipe opening 71 and / or the inner side of the second pipe opening 81 .

[0045] The above-mentioned dispenser also includes a sensing member 10 arranged on the first limit member 32 and a proximity switch 11 arranged on the movable bracket 6. The proximity switch 11 is aligned with the groove 91 along the radial direction of the cylindrical body 31. The proximity switch 11 is used to sense the sensing member 10 when it is aligned with the sensing member 10 along the first direction.

[0046] Because the shell 3 rotates synchronously with the shaft 2 during normal production of the filling equipment, it is difficult to ensure that the first limit member 32 and the second limit member 9 are aligned along the first direction when entering the cleaning stage. Therefore, the control unit is required to control the whole machine to rotate slowly until the proximity switch 11 and the sensing member 10 are aligned along the first direction. The proximity switch 11 senses the sensing member 10. At this time, the control unit controls the whole machine to stop rotating, so that the shaft 2 and the shell 3 stop rotating synchronously, so that when the moving bracket 6 moves from the second position to the first position relative to the shell 3, the first limit member 32 can enter the groove 91 of the second limit member 9, thereby accurately realizing the limiting and anti-rotation of the shell 3.

[0047] See also Figure 1-4 As shown, the distributor also includes a guide sleeve 13 arranged on the mounting seat 5, and a guide shaft 14 that can be movably inserted into the mounting seat 5 along a first direction. The guide shaft 14 is coaxially inserted into the guide sleeve 13 and is longer than the guide sleeve 13. One end of the guide shaft 14 is connected to the movable bracket 6, and the other end of the guide shaft 14 is provided with a limiting portion 15 for preventing it from passing out of the mounting seat 5.

[0048] In this embodiment, one end of the guide shaft 14 close to the housing 3 (ie, the upper end) is connected to the motion bracket 6 , and one end of the guide shaft 14 away from the housing 3 (ie, the lower end) is provided with the limiting portion 15 .

[0049] Through this arrangement, when the moving bracket 6 is in the first position relative to the housing 3, the limiting portion 15 abuts upward against the lower surface of the mounting seat 5; when the moving bracket 6 is in the second position relative to the housing 3, the moving bracket 6 abuts downward against the upper end surface of the guide sleeve 13.

[0050] In this embodiment, there are two medium channels 21, and correspondingly, there are two first pipes 7 and two second pipes 8. According to actual needs, the medium channels 21 can be used as liquid inlet channels or as reflux channels, and the number of the medium channels 21 can also be increased or decreased according to actual needs.

[0051] The working process of this embodiment is described in detail below:

[0052] When the filling device is in the working stage, the movable bracket is in the second position relative to the housing 3, the driving member 16 drives the movable bracket downward to abut against the upper end surface of the guide sleeve 13, the first pipe 7 and the second pipe 8 are disengaged from each other, the first stopper 32 and the second stopper 9 are disengaged from each other, and the housing 3 can rotate synchronously with the rotating shaft 2;

[0053] When the filling equipment switches to the cleaning stage, the control unit controls the whole machine to rotate slowly until the proximity switch 11 is aligned with the sensing element 10 in the up and down direction, and the proximity switch 11 senses the sensing element 10. At this time, the control unit controls the whole machine to stop rotating, and the rotating shaft 2 and the housing 3 stop rotating synchronously. The driving member 16 drives the movable bracket to move upward until the limiting portion 15 presses upward against the lower end surface of the mounting seat 5. At this time, the movable bracket 6 moves from the second position to the first position relative to the housing 3, the first pipe 7 and the second pipe 8 are connected to each other, and the first limiting member 32 enters the groove 91 of the second limiting member 9. When the rotating shaft 2 continues to rotate, it can prevent the housing 3 from rotating with the rotating shaft 2, thereby realizing dynamic and static sealing.

[0054] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
