[0043] One prior art star wheel structure employs a support rod supported between a bottle hanging star wheel and a bottle body star wheel. The bottle hanging star wheel and the support rod are connected by a first screw, and the bottle body star wheel and the support rod are connected by a second screw, so that the bottle hanging star wheel and the bottle body star wheel can be used in conjunction with each other. However, for bottles of different sizes, different bottle body star wheels need to be replaced to adapt to the bottles.

[0045] like Figures 1 to 8As shown, the utility model provides a star wheel structure, which includes a bottle hanging structure 1, a bottle body star wheel 2 and a quick release structure 3. The bottle hanging structure 1 and the bottle body star wheel 2 are spaced apart along a first orientation. The quick release structure 3 includes a fixed rod 31 and a rotating rod 32. The first end of the rotating rod 32 is rotatably connected to one of the bottle hanging structure 1 and the bottle body star wheel 2, and the first end of the fixed rod 31 is fixedly connected to the other of the bottle hanging structure 1 and the bottle body star wheel 2. One of the second end of the fixed rod 31 and the second end of the rotating rod 32 is provided with a connecting plug groove 311 and a hanging groove 312 along the first orientation, and the other is provided with a plug portion 321 and a hanging portion 322 connected to the outer periphery of the plug portion 321. The hanging groove 312 is provided with a hanging surface 3121, and the hanging surface 3121 is located at the connection point between the plug groove 311 and the hanging groove 312 along the first orientation. The inserting portion 321 can be inserted into the inserting slot 311 so that the hanging portion 322 is inserted into the hanging slot 312. The inserting portion 321 can rotate relative to the inserting slot 311 so that the hanging portion 322 is hung on the hanging surface 3121.

[0046] When assembling the bottle body star wheel 2 to the bottle hanging structure 1, the insertion portion 321 is inserted into the insertion groove 311, so that the hanging portion 322 is inserted into the hanging groove 312. When the hanging portion 322 is inserted into the hanging groove 312, the rotating rod 32 is rotated so that the hanging portion 322 is hooked to the hanging surface 3121. When the hanging portion 322 is hooked to the hanging surface 3121, the relative positions of the fixing rod 31 and the rotating rod 32 in the first orientation are fixed, thereby fixing the relative positions of the bottle hanging structure 1 and the bottle body star wheel 2 in the first orientation. This allows the bottle body star wheel 2 and the bottle hanging structure 1 to be efficiently and conveniently assembled into a whole via the quick-release structure 3.

[0047] When the bottle star wheel 2 is to be detached, the rotating rod 32 is rotated to separate the hanging portion 322 from the hanging surface 3121, and then the rotating rod 32 is moved away from the fixed rod 31 along the first direction until the rotating rod 32 and the fixed rod 31 are separated. In this way, the bottle star wheel 2 can be detached from the bottle hanging structure 1 efficiently and conveniently through the quick-release structure 3.

[0048] Therefore, by adopting this star wheel structure, the bottle body star wheel 2 and the bottle hanging structure 1 can be assembled into a whole efficiently and conveniently, and the bottle body star wheel 2 can be removed from the bottle hanging structure 1 efficiently and conveniently through the quick-release structure 3, saving time and effort; secondly, it can effectively avoid the problem of damage or even failure of screws and / or threaded holes caused by multiple installation and removal of screws in the prior art.

[0049] In this embodiment, if Figure 1 and Figure 3As shown, the first end of the fixed rod 31 is exemplarily fixedly connected to the bottle hanging structure 1, and the first end of the rotating rod 32 is rotatably connected to the bottle body star wheel 2. In other embodiments, the first end of the fixed rod 31 can also be fixedly connected to the bottle body star wheel 2, and the first end of the rotating rod 32 can be rotatably connected to the bottle hanging structure 1.

[0050] In this embodiment, if Figure 1 、 Figures 3 to 7 As shown, the second end of the fixed rod 31 is exemplarily provided with a connecting slot 311 and a hanging slot 312, and the second end of the rotating rod 32 is provided with a plug portion 321 and a hanging portion 322 connected to the outer periphery of the plug portion 321. In other embodiments, the second end of the fixed rod 31 may be provided with a plug portion 321 and a hanging portion 322 connected to the outer periphery of the plug portion 321, and the second end of the rotating rod 32 may be provided with a connecting slot 311 and a hanging slot 312.

[0051] Among them, such as Figures 3 to 7 As shown, the insertion slot 311 includes a first sub-insertion slot 3111 and a second sub-insertion slot 3112 recessed in the inner circumferential wall of the first sub-insertion slot 3111. The insertion portion 321 can be inserted into the first sub-insertion slot 3111, and the hanging portion 322 can be inserted into the second sub-insertion slot 3112. In this way, the hanging portion 322 can pass through the insertion slot 311 and enter the hanging slot 312.

[0052] It is understandable that if Figures 3 to 5 As shown, the orthographic projection of the first sub-plugging slot 3111 along the first orientation and the orthographic projection of the second sub-plugging slot 3112 along the first orientation both fall within the orthographic projection of the hanging slot 312 along the first orientation.

[0053] Preferably, if Figure 3 、 Figure 6 and Figure 7 As shown, there are multiple hanging parts 322, and the multiple hanging parts 322 are distributed at intervals along the circumference of the plug-in part 321. Figures 3 to 5 As shown, there are multiple second sub-plug-in slots 3112, and the multiple hanging parts 322 are arranged in a one-to-one correspondence with the multiple second sub-plug-in slots 3112. Furthermore, the hanging surface 3121 is divided into multiple hanging sub-surfaces by the second sub-plug-in slots 3112, and the multiple hanging sub-surfaces, the multiple hanging parts 322 and the multiple second sub-plug-in slots 3112 are all arranged in a one-to-one correspondence. This can improve the connection stability of the fixed rod 31 and the rotating rod 32. In this embodiment, as shown in FIG. Figures 3 to 7 As shown, preferably, the number of the hanging portion 322 , the second sub-plugging slot 3112 and the hanging sub-surface are all two, which can ensure the connection stability and reduce the processing difficulty of the fixed rod 31 and the rotating rod 32 .

[0054] Optionally, the quick-release structure 3 further includes a locking member 33. The locking member 33 can pass through one of the insertion slots 311 provided in the fixed rod 31 and the rotating rod 32 in the second orientation and engage with one of the insertion portions 321 provided in the fixed rod 31 and the rotating rod 32. The first orientation and the second orientation are arranged at an angle. This allows the relative position of the fixed rod 31 and the rotating rod 32 to be locked, thereby further improving the connection reliability of the quick-release structure 3 and the operating reliability and stability of the star wheel structure.

[0055] As an alternative, the quick-release structure 3 further includes a locking member 33. In the second orientation, the locking member 33 is threadedly connected to one of the insertion slots 311 provided in the fixed rod 31 and the rotating rod 32, and is inserted into or abutted against one of the insertion portions 321 provided in the fixed rod 31 and the rotating rod 32. The first and second orientations are arranged at an angle. This also locks the relative position of the fixed rod 31 and the rotating rod 32, thereby further improving the connection reliability of the quick-release structure 3 and the operational reliability and stability of the star-wheel structure. Furthermore, it also prevents the locking member 33 from falling or even being lost.

[0056] In this embodiment, if Figure 1 and Figure 3 As shown, preferably, the locking member 33 is threadedly connected to the fixed rod 31 and plugged into the rotating rod 32. Specifically, as Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, the fixed rod 31 is provided with a threaded hole 313 extending radially through the insertion groove 311. The insertion portion 321 is provided with an insertion hole 3211. The locking member 33 is threadedly connected to the threaded hole 313 and inserted into the insertion hole 3211. This prevents the locking member 33 from falling or even being lost. Furthermore, compared to the locking member 33 being pressed against the rotating rod 32, the locking member 33 being inserted into the rotating rod 32 further improves the reliability of locking the relative position of the fixed rod 31 and the rotating rod 32. Furthermore, compared to the locking member 33 being pressed against the rotating rod 32, the locking member 33 being inserted into the rotating rod 32 prevents damage to the rotating rod 32. In this embodiment, the locking member 33 is a second screw.

[0057] In this embodiment, the first orientation and the second orientation are preferably perpendicular to each other, which facilitates the processing of the threaded hole 313 and the insertion hole 3211. In other embodiments, the first orientation and the second orientation may be arranged at an acute angle or an obtuse angle.

[0058] Among them, such as Figure 1 and Figure 3 As shown, the quick-release structure 3 further includes a screw connection structure, and the screw connection structure includes a first screw 34 .

[0059] In this embodiment, if Figure 1 and Figure 3As shown, the first end of the rotating rod 32 passes through the mounting hole of the bottle body star wheel 2 in a first orientation and is threadedly connected to the first screw 34. The bottle body star wheel 2 is supported on the first screw 34, and the first end of the rotating rod 32 is loosely fitted in the mounting hole to achieve rotational connection between the first end of the rotating rod 32 and the bottle body star wheel 2.

[0060] In other embodiments, the first end of the rotating rod 32 passes through the mounting hole of the bottle hanging structure 1 in a first orientation and is threadedly connected to the first screw 34. The first screw 34 is supported on the support surface of the bottle hanging structure 1, and the first end of the rotating rod 32 is loosely fitted in the mounting hole to achieve rotational connection between the first end of the rotating rod 32 and the bottle hanging structure 1. Specifically, the support surface is the upper end surface of the bottle hanging structure 1.

[0061] Preferably, if Figure 3 As shown, the screw connection structure further includes a washer 35 , and the first screw 34 passes through the washer 35 and is threadedly connected to the first end of the rotating rod 32 . In this embodiment, the bottle body star wheel 2 is supported on the washer 35 .

[0062] Further preferably, in this embodiment, the gasket 35 is provided with a first mark; and / or the bottle body star wheel 2 is provided with a second mark. When replacing the bottle body star wheel 2, the first mark and / or the second mark can be used to conveniently determine whether the selected bottle body star wheel 2 is the intended bottle body star wheel.

[0063] Further preferably, in this embodiment, if Figure 3 As shown, there are multiple washers 35, and the first screw 34 passes through the washers 35 and is threadedly connected to the first end of the rotating rod 32. The first markings of the multiple first washers 35 are different. In this case, preferably, the first markings of the multiple first washers 35 are different, and the bottle star wheel 2 is provided with a second marking. The second markings of the bottle star wheels 2 of different sizes are also different. This facilitates determining whether the selected bottle star wheel 2 is compatible with the rotating rod 32 by using the second marking and the multiple first markings.

[0064] Further preferably, in this embodiment, the plurality of first identifiers are color identifiers, and the colors of the plurality of first identifiers are different. The second identifier is also a color identifier. In this embodiment, if Figure 3 As shown, the second mark is a color column 23 provided on the bottle body star wheel 2. The color column 23 is inserted or screwed or clamped on the bottle body star wheel 2 by interference.

[0065] In other embodiments, the first and second identifiers may both be symbolic identifiers. Alternatively, the first and second identifiers may both be numerical identifiers. This facilitates determining whether the selected bottle star wheel 2 is compatible with the rotating rod 32 by using the second identifier and multiple first identifiers.

[0066] Alternatively, as Figure 2As shown, the star wheel structure also includes a guide post 41, one axial end of which is fixedly connected to the bottle hanging structure 1. The bottle star wheel 2 is provided with an anti-rotation hole 21, and the guide post 41 is configured to engage with the anti-rotation hole 21 in a first orientation. This prevents the bottle star wheel 2 from rotating after the fixed rod 31 and the rotating rod 32 are fixed relative to each other in the first orientation, further improving the operational reliability and stability of the star wheel structure.

[0067] Specifically, the guide column 41 is a prism, and the anti-rotation hole 21 is adapted to the cross-sectional shape of the guide column 41 along the length direction.

[0068] As an alternative, Figure 2 As shown, the guide post 41 is a cylinder, the anti-rotation hole 21 is a circular hole, and the number of the guide posts 41 and the anti-rotation hole 21 is at least two, with at least two guide posts 41 and at least two anti-rotation holes 21 provided in a one-to-one correspondence. This also prevents the bottle star wheel 2 from rotating after the fixing rod 31 and the rotating rod 32 are fixed relative to each other in the first orientation.

[0069] In this embodiment, if Figure 2 As shown, the exemplary guide column 41 is a cylinder, the anti-rotation hole 21 is a circular hole, the number of the guide column 41 and the number of the anti-rotation hole 21 are both two, and the two guide columns 41 and the two anti-rotation holes 21 are arranged in a one-to-one correspondence.

[0070] Preferably, if Figure 2 As shown, the length of the guide post 41 is greater than the maximum distance between the bottle hanging structure 1 and the bottle body star wheel 2 in the first orientation. Therefore, after the relative positions of the fixing rod 31 and the rotating rod 32 in the first orientation are fixed, the guide post 41 can effectively prevent the bottle body star wheel 2 from rotating further.

[0071] Among them, such as Figure 1 and Figure 2 As shown, the bottle hanging structure 1 includes a bottle hanging star wheel 11 and a mounting seat 12, and the bottle hanging star wheel 11 is connected to the outer periphery of the mounting seat 12. In this embodiment, the inner periphery of the bottle hanging star wheel 11 is supported on the outer periphery of the mounting seat 12. The bottle hanging star wheel 11 is threadedly connected to the outer periphery of the mounting seat 12 by a third screw 13. The first end of the fixing rod 31 is inserted into the mounting seat 12 and is threadedly connected to the mounting seat 12 by a fourth screw 36. One end of the guide column 41 along the axial direction is inserted into the mounting seat 12 and is threadedly connected to the mounting seat 12 by a fifth screw 42. Among them, the specific structure of the mounting seat 12 belongs to the prior art and will not be repeated here.

[0075] The present invention also provides a star-wheel transmission mechanism, including a rotary drive mechanism and the aforementioned star-wheel structure. The output end of the rotary drive mechanism is fixedly connected to the central area of ​​the bottle hanging structure 1 and can drive the bottle hanging structure 1 to rotate around its own central axis. By adopting the aforementioned star-wheel structure, the bottle body star-wheel 2 and the bottle hanging structure 1 can be efficiently and conveniently assembled into a whole, and the bottle body star-wheel 2 can be efficiently and conveniently removed from the bottle hanging structure 1 via the quick-release structure 3, saving time and effort. Secondly, it can effectively avoid the problem of damage or even failure of screws and / or threaded holes caused by multiple installation and removal of screws in the prior art. Among them, the specific structure of the rotary drive mechanism belongs to the prior art and will not be repeated here.

[0076] Specifically, the output end of the rotary drive mechanism is fixedly connected to the central area of ​​the mounting seat 12, so as to be able to drive the star wheel structure to rotate around its own central axis.

The multiple quick-release structures 3 are divided into at least two groups, and the at least two bottle star wheels 2 are arranged in a one-to-one correspondence with the at least two groups of quick-release structures 3. The at least two bottle star wheels 2 are arranged around the outer periphery of the rotary drive mechanism to form an annular bottle star wheel. This allows the bottle star wheel 2 and the bottle hanging structure 1 to be assembled efficiently and conveniently after the star wheel structure and the rotary drive mechanism are assembled into a whole structure, and the bottle star wheel 2 can be efficiently and conveniently detached from the bottle hanging structure 1 via the quick-release structures 3.

[0078] In this embodiment, if Figure 1 、 Figure 2 and Figure 8As shown, the exemplary arrangement includes two bottle star wheels 2, with each set of quick-release structures 3 comprising two quick-release structures 3. Each bottle star wheel 2 is assembled to the bottle hanging structure 1 via the two quick-release structures 3. Once assembled to the bottle hanging structure 1, the bottle star wheel 2 cannot be rotated, thereby effectively improving the operational reliability and stability of the star wheel structure.

[0079] It is understandable that if Figure 1 and Figure 2 As shown, the central axis of the bottle hanging structure 1, the rotation center line of the bottle hanging structure 1, the central axis of the annular bottle body star wheel, the rotation center line of the annular bottle body star wheel and the rotation center line of the bottle body star wheel 2 are all collinear.
