[0069] The inner diameter of the first large hole 312 is larger than the outer diameter of the lower end of the rotating seat 23;

[0070] That is, the inner diameter of the first large hole 312 is defined as a size larger than the rotating outer diameter of all the 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 the rotating parts below it can be taken out from the second large hole 312.

[0071] like Figure 1 to Figure 2As shown, in some embodiments of the present invention, a fastening threaded hole (not shown in the figure) connected to the adjusting threaded hole may be opened on the outer surface of the support 12, and a fastening bolt is installed in the fastening threaded hole, and one end of the fastening bolt passes through the fastening threaded hole and is in close contact with the adjusting screw 13;

[0072] A fastening bolt is provided to further limit and fix the position of the adjusting screw 13 when the maintenance device 1 supports the star wheel disc 3 during the maintenance process, so as to prevent the adjusting screw 13 from being shifted in position and affecting the subsequent height stability of the star wheel disc 3.

[0073] In a second aspect, the present invention further provides a star wheel shaft seat maintenance method, which is performed using the star wheel shaft seat maintenance device provided by the embodiment of the first aspect of the present invention. Specifically, the maintenance method comprises the following steps:

[0074] S1. When performing maintenance, start the device so that the first step hole 311 corresponds to the adjustment screw 13, loosen the second fastening screw 15, and ensure that the maintenance device 1 can rotate;

[0075] S2, rotating the adjusting screw 13 to move upward, and rotating the maintenance device 1, so that the heads of all the adjusting screws 13 extend into the first step hole 311 and support the first step hole 311;

[0076] S3, locking the two locking sleeves 11 so that the two locking sleeves 11 are tightly held on the outside of the shaft sleeve 21. Specifically, the locking sleeves 11 are locked using the second fastening screws 15 so that the maintenance device 1 is tightly held in the annular locking groove 211.

[0077] S4, separate the rotating seat 23 and the flange seat 31, adjust the screw 13 to support the flange seat 31 and the star wheel 3, take the rotating seat 23 out of the first large hole 312 on the flange seat 31, and perform maintenance operations on the parts in the sleeve 21 (i.e., the component to be maintained 22) through the first large hole 312 on the flange seat 31;

[0078] In this step, the rotating seat 23 and the flange seat 31 are separated by loosening the third fastening screw 24 to separate the rotating seat 23 and the flange seat 31;

[0079] S5. After the maintenance operation is completed, the rotating seat 23 and the flange seat 31 are assembled. After the assembly is completed, the adjusting screw 13 is rotated to move downward until the head of the adjusting screw 13 is completely disengaged from the first step hole 311, and the maintenance process is ended;

[0080] Step S5 is specifically as follows: after the maintenance operation is completed, the shaft seat 2 is assembled, the rotating seat 23 is rotated until the mounting hole (i.e., threaded hole 1) of the third fastening screw 24 thereon corresponds to the mounting hole (i.e., threaded hole 3) of the flange seat 31, and the third fastening screw 24 is locked. The adjusting screw 13 is twisted downward by a wrench until the adjusting screw 13 is completely disengaged from the first step hole 311 and there is a certain safety distance, and the entire maintenance process is completed.

[0081] The present invention provides a method and device for maintaining a star wheel shaft seat. Since a maintenance device 1 is provided, when the upper star wheel disc 3 is larger, the star wheel disc 3 can be supported, and the disassembly and assembly of the rotating seat 23 is more convenient. In the present invention, since the maintenance device 1 occupies a small space and can be mounted on the outside of the shaft sleeve 21, it is suitable for maintenance use when the operating space is small. In addition, in the actual maintenance process, since the adjusting screw 13 on the maintenance device 1 is used to support the star wheel disc 3, after the maintenance is completed, the installation of the rotating seat 23 can be restored without the need to adjust the height of the star wheel disc 3 a second time.

[0082] The present invention provides a method and device for maintaining a star wheel shaft seat. The maintenance device 1 has a simple structure, occupies a small space, and has low cost. It is not only applicable to the maintenance of the star wheel shaft seat provided by the present invention, but also applicable to the maintenance of other similar structures.
