[0036] The dispenser further comprises a mounting seat 5, a moving support 6 movably arranged on the mounting seat 5 along a first direction, a first pipeline 7 arranged on the outer shell 3 and communicated with the medium channel 21, a second pipeline 8 arranged on the moving support 6, and an anti-rotation mechanism. In the embodiment, the first direction is parallel to the rotating shaft 2, the outer shell 3, the moving support 6 and the mounting seat 5 are located on the same side of the rotating disc 1 and arranged in sequence along the first direction; the dispenser further comprises a driving member 16 arranged on the mounting seat 5, which is used to drive the moving support 6 to move back and forth along the first direction.

[0037] The moving support 6 can move close to or away from the outer shell 3 along the first direction, and the moving support 6 has a first position and a second position relative to the outer shell 3:

[0038] Referring to Figures 3-4 As shown in the drawings, when the moving support 6 is at the first position relative to the outer shell 3, the second pipeline 8 and the first pipeline 7 are connected, and the anti-rotation mechanism is used to abut against the outer shell 3 to prevent it from rotating with the rotating shaft 2;

[0039] Referring to Figures 1-2 As shown in the drawings, when the moving support 6 is at the second position relative to the outer shell 3, the second pipeline 8 and the first pipeline 7 are disconnected, the anti-rotation mechanism is disconnected from the outer shell 3, and the outer shell 3 can rotate with the rotating shaft 2.

[0040] The outer shell 3 comprises a cylindrical body 31 sleeved outside the rotating shaft 2, and a first limiting member 32 arranged on the outer circumferential part of the cylindrical body 31; the anti-rotation mechanism comprises a second limiting member 9 arranged on the moving support 6. Among the first limiting member 32 and the second limiting member 9, one of them is provided with a groove 91, and the other is used to be inserted into the groove 91 when the moving support 6 is at the first position relative to the outer shell 3.

[0041] In the embodiment, the first limiting member 32 is radially outwardly arranged on the outer circumferential portion of the cylindrical body 31, and the second limiting member 9 is provided with an upwardly open groove 91, and the arrangement direction of the groove walls on both sides of the groove 91 is perpendicular to the rotation axis of the rotating shaft 2. Through the arrangement, when the first limiting member 32 extends into the groove 91, the cylindrical body 31 can be limited to avoid rotating with the rotating shaft 2.

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

[0046] Since the shell 3 rotates synchronously with the rotating shaft 2 during normal production of the filling device, and it is difficult to ensure that the first limiting member 32 and the second limiting member 9 are aligned in the first direction when entering the cleaning stage, the control unit needs to control the slow rotation of the whole machine until the proximity switch 11 senses the sensing member 10 when the proximity switch 11 and the sensing member 10 are aligned in the first direction, at which time the control unit controls the whole machine to stop rotating, so that the rotating shaft 2 and the shell 3 stop rotating synchronously, so that when the moving support 6 moves from the second position to the first position relative to the shell 3, the first limiting member 32 can enter the groove 91 of the second limiting member 9, and the limiting and anti-rotation of the shell 3 are accurately realized.

[0047] Referring to Figures 1-4 As shown in the figure, the dispenser further includes a guide sleeve 13 arranged on the mounting seat 5, and a guide shaft 14 movably arranged in the mounting seat 5 in the first direction, the guide shaft 14 is coaxially arranged in the guide sleeve 13 and longer than the guide sleeve 13, one end of the guide shaft 14 is connected with the moving support 6, and the other end of the guide shaft 14 is provided with a limiting portion 15 for preventing the guide shaft 14 from penetrating out of the mounting seat 5.

[0048] In the embodiment, the guiding shaft 14 is connected with the moving support 6 at one end (i.e. the upper end) close to the shell 3, and the limiting part 15 is arranged at the other end (i.e. the lower end) away from the shell 3.

[0049] Through the arrangement, when the moving support 6 is in the first position relative to the shell 3, the limiting part 15 abuts against the lower surface of the mounting seat 5 upwardly; and when the moving support 6 is in the second position relative to the shell 3, the moving support 6 abuts against the upper end surface of the guiding sleeve 13 downwardly.

[0050] In the embodiment, the medium channel 21 has two channels, and correspondingly, the first pipe 7 and the second pipe 8 also have two channels respectively. According to actual needs, the medium channel 21 can be used as a liquid inlet channel or a return channel, and the number of the medium channel 21 can be increased or decreased according to actual needs.

[0051] The working process of the embodiment will be described in detail as follows:

[0052] When the filling device is in the working stage, the moving support is in the second position relative to the shell 3, the driving member 16 drives the moving support to abut against the upper end surface of the guiding sleeve 13 downwardly, the first pipe 7 and the second pipe 8 are separated from each other, the first limiting part 32 and the second limiting part 9 are separated from each other, and the shell 3 can rotate synchronously with the rotating shaft 2;

[0053] When the filling device is switched to the cleaning stage, the control unit controls the whole machine to rotate slowly until the proximity switch 11 is aligned with the sensing member 10 in the up-down direction, the proximity switch 11 senses the sensing member 10, at this time, the control unit controls the whole machine to stop rotating, the rotating shaft 2 and the shell 3 stop rotating synchronously, the driving member 16 drives the moving support to move upwardly until the limiting part 15 abuts against the lower end surface of the mounting seat 5 upwardly, at this time, the moving support 6 moves from the second position to the first position relative to the shell 3, the first pipe 7 and the second pipe 8 are connected with each other, and the first limiting part 32 enters the groove 91 of the second limiting part 9, when the rotating shaft 2 continues to rotate, the shell 3 can be prevented from rotating with the rotating shaft 2, and dynamic and static sealing is realized.

[0054] The above embodiments are only for illustrating the technical concept and characteristics of the present application, the purpose of which is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application, and any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
