[0002] In the bottling of wine, beverages, and condiments, bottle conveying is achieved by rotating a shaft to drive a star wheel, allowing bottles to be transferred between the star wheels.

[0003] As a rotary motion mechanism, the bearing housing contains a series of bearing combinations and oil seal structures. These parts will inevitably wear during the rotary motion process, so they will be listed as key items for maintenance and overhaul.

[0004] Due to the special structure of the star wheel bearing seat in the filling machine, and the strict requirements on the conveying height of the filling star wheel, as well as the certain limitations on the filling space, the maintenance of the bearing seat presents many inconveniences. These include: First, when the star wheel is large, disassembly and assembly are difficult; Secondly, there is insufficient maintenance space, especially for the ultra-clean and sterile models on the market now. With fully enclosed protection, workers do not have enough operating space inside, making disassembly and assembly difficult. Third, the transfer of PET bottles between the star wheels is accomplished by clamping the bottle mouth, which requires strict control over the clamping height. Therefore, adjusting the height of the star wheels is difficult after maintenance. Summary of the Invention

The star wheel 3 is detachably mounted on the flange seat 31, and the detachable connection method includes, but is not limited to, bolt connection. Specifically, the bushing 21 is the foundation for supporting and fixing the entire bearing seat 2; inside the bushing 21, there is also a component 22 to be maintained, which includes a series of bearing combinations and oil seal structures located inside the bushing. These parts are subject to wear during rotation and are key items for maintenance and overhaul. The rotating seat 23 is a rotating part of the bearing seat 2. In this invention, the height of the rotating seat 23 can be adjusted up and down. Maintenance device 1 is located outside the bushing 21. Maintenance device 1 includes two oppositely arranged locking sleeves 11. Multiple supports 12 are provided outside the locking sleeves 11. Adjustment thread holes are opened in the supports 12. Adjustment screws 13 are threadedly connected in the adjustment thread holes. The head of the adjustment screws 13 is in contact with the bottom of the flange seat 31. Specifically, of the two locking sleeves 11, the two ends of one locking sleeve 11 are detachably connected to the two ends of the other locking sleeve 11; the two locking sleeves 11 are detachably connected, and the detachable connection method includes, but is not limited to, bolt connection. Multiple supports 12 are detachably disposed on the outside of the lock sleeve 11, and the detachable connection methods include, but are not limited to, bolt connection methods.

[0023] like Figures 1 to 2 As shown, in some embodiments of the present invention, the top of the rotating seat 23 is provided with a threaded hole (not shown in the figure) along the circumferential direction, and a third fastening screw 24 is connected to the threaded hole. The top of the star wheel disk 3 has a threaded hole (not shown in the figure) corresponding to the third fastening screw 24 along the circumferential direction. The top of the flange seat 31 has a threaded hole three (not shown in the figure) corresponding to the third fastening screw 24 along the circumferential direction. The star wheel 3, the rotating seat 23, and the flange seat 31 are connected and fixed by the third fastening screw 24. When the rotating seat 23 rotates, it can drive the star wheel 3 to rotate. Specifically, the bottom of the middle area of ​​the star wheel 3 is in close contact with the top of the rotating seat 23, and the bottom edge of the star wheel 3 is in close contact with the flange seat 31.

[0024] like Figures 1 to 2As shown, in some embodiments of the present invention, a threaded connection hole (not shown in the figure) is provided at the lower end of the support 12, and a first fastening screw 14 is threadedly connected in the threaded connection hole. A threaded mounting hole (not shown in the figure) corresponding to the first fastening screw 14 is provided on the outside of the locking sleeve 11. The support 12 is fixed to the outside of the lock sleeve 11 by the first fastening screw 14.

[0025] like Figures 1 to 2 As shown, in some embodiments of the present invention, the locking sleeve 11 is semi-circular, and of the two locking sleeves 11, the two ends of one locking sleeve 11 are detachably connected to the two ends of the other locking sleeve 11. Specifically, each lock sleeve 11 has a connecting end integrally formed at one end, and the connecting end has a lock sleeve threaded hole one (not shown in the figure), and each lock sleeve 11 has a lock sleeve threaded hole two (not shown in the figure) at the other end. A second fastening screw 15 can be installed in both the first threaded hole of the locking sleeve (not shown in the figure) and the second threaded hole of the locking sleeve (not shown in the figure); One end of one of the lock sleeves 11 is provided with a connecting end, and is connected and fixed to the other end of the lock sleeve 11 with a lock sleeve threaded hole 2 by a second fastening screw 15, so as to realize the detachable connection between the two lock sleeves 11.

[0026] like Figures 1 to 2 As shown, in some embodiments of the present invention, an annular locking groove 211 is provided at one end of the bushing 21 near the rotating seat 23; The maintenance device 1 is compatible with the annular locking groove 211; specifically, during actual installation, the two locking sleeves 11 can be adapted to be installed in the annular locking groove 211. The annular locking groove 211 is provided to prevent the maintenance device 1 from slipping off when the maintenance device 1 is fitted onto the outside of the bushing 21 and the pressure above the maintenance device 1 is too great (such as when the star wheel 3 is heavy), which would require a second determination of the height of the star wheel 3.

[0027] like Figures 1 to 2 As shown, in some embodiments of the present invention, the bottom of the flange seat 31 is provided with a first stepped hole 311 along the circumferential direction; The cross-section of the first stepped hole 311 is circular, and the diameter of the first stepped hole 311 gradually increases from top to bottom; specifically, the shape of the vertical cross-section of the first stepped hole 311 can be trapezoidal or convex. The head of the adjusting screw 13 is adapted to the first stepped hole 311; specifically, the head of the adjusting screw 13 being adapted to the first stepped hole 311 means that the head of the adjusting screw 13 can be adapted to be inserted into the first stepped hole 311. Since the diameter of the first stepped hole 311 gradually increases from top to bottom, when the head of the adjusting screw 13 is inserted into the first stepped hole 311, it will press against the first stepped hole 311. That is, the adjusting screw 13 can press against the flange seat 31, which can support the flange seat 31 and prevent the flange seat 31 from rotating or shaking.

[0028] like Figures 1 to 2 As shown, in some embodiments of the present invention, a first large hole 312 is provided at the bottom of the flange seat 31; The upper end of the rotating seat 23 is located above the first large hole 312, and the lower end of the rotating seat 23 is located below the first large hole 312. The inner diameter of the first large hole 312 is larger than the outer diameter of the lower end of the rotating seat 23; That is, the inner diameter of the first large hole 312 is defined as being larger than the outer diameter of all rotating parts below it (i.e., the part of the rotating seat 23 located below the first large hole 312), thereby ensuring that the parts of all rotating parts below it can be removed from the first large hole 312.

[0029] like Figures 1 to 2 As shown, in some embodiments of the present invention, a fastening threaded hole (not shown in the figure) communicating with the adjusting threaded hole can be provided on the outer surface of the support 12, and a fastening bolt is installed in the fastening threaded hole, with one end of the fastening bolt passing through the fastening threaded hole in close contact with the adjusting screw 13. The device is equipped with fastening bolts to further limit and fix the position of the adjusting screw 13 when the maintenance device 1 supports the star wheel 3 during maintenance, so as to prevent the adjusting screw 13 from shifting position and affecting the subsequent height stability of the star wheel 3.

[0030] Secondly, the present invention also provides a method for maintaining a star wheel bearing seat. This method uses the star wheel bearing seat maintenance device provided in the embodiment of the first aspect of the present invention. Specifically, the method includes the following steps: S1. When performing maintenance, start the equipment so that the first step hole 311 corresponds to the adjusting screw 13, loosen the second fastening screw 15, and ensure that the maintenance device 1 can rotate. S2. Rotate the adjusting screw 13 upward and rotate the maintenance device 1 so that the heads of all adjusting screws 13 extend into the first step hole 311 and press against the first step hole 311. S3. Tighten the two locking sleeves 11 so that the two locking sleeves 11 are tightly held on the outside of the bushing 21. Specifically, use the second fastening screw 15 to tighten the locking sleeves 11 and hold the maintenance device 1 in the annular locking groove 211. S4. Disconnect the rotating seat 23 from the flange seat 31. Adjust the screw 13 to support the flange seat 31 and the star wheel 3. Remove the rotating seat 23 from the first large hole 312 on the flange seat 31. Perform maintenance operations on the components (i.e. the components to be maintained 22) inside the bushing 21 through the first large hole 312 on the flange seat 31. In this step, the rotating seat 23 and the flange seat 31 are separated by loosening the third fastening screw 24. S5. After the maintenance operation is completed, assemble the rotating seat 23 and the flange seat 31. After assembly, rotate the adjusting screw 13 downward until the head of the adjusting screw 13 is completely disengaged from the first step hole 311, and the maintenance process ends. Step S5 is as follows: After the maintenance operation is completed, assemble the bearing seat 2, rotate the rotating seat 23 until the mounting hole (i.e., threaded hole one) of the third fastening screw 24 corresponds to the mounting hole (i.e., threaded hole three) of the flange seat 31, and tighten the third fastening screw 24. Turn the wrench to move the adjusting screw 13 downwards until the adjusting screw 13 is completely disengaged from the first step hole 311 and there is a certain safe distance, then the entire maintenance process is complete.

[0031] The present invention provides a method and apparatus for maintaining a star wheel bearing seat. Because of the maintenance device 1, even when the upper star wheel disk 3 is large, it can still provide support for the star wheel disk 3, making the disassembly and assembly of the rotating seat 23 more convenient. In this invention, because the maintenance device 1 occupies little space and can be fitted onto the outside of the bushing 21, it is suitable for maintenance in situations where the operating space is limited. Furthermore, during actual maintenance, since the adjusting screw 13 on the maintenance device 1 is used to support the star wheel disk 3, after maintenance, the rotating seat 23 can be restored to its original position without the need for secondary adjustment of the star wheel disk 3's height.

[0032] The present invention provides a method and apparatus for maintaining a star wheel bearing seat. The maintenance apparatus 1 has a simple structure, occupies little space, and has low cost. It is applicable not only to the maintenance of the star wheel bearing seat provided by the present invention, but also to the maintenance of other similar structures.

[0033] This invention provides a method and apparatus for maintaining a star wheel bearing seat. The locking sleeve 11 is a half structure and the up-and-down movement mode of the adjusting screw 13 is only one embodiment. Other forms of locking, fixing structures or movement modes that do not change the principle of the method should be covered within the protection scope of this invention.
