[0025] like Figures 1 to 3 As shown, this embodiment proposes an adjustable eccentric guide wheel, including a mounting base 1, an eccentric shaft 2 on the mounting base 1, and a guide wheel 3 sleeved on the eccentric shaft 2; in addition, at least one bearing 4 is provided between the eccentric shaft 2 and the guide wheel 3, and by providing the bearing 4, the eccentric shaft 2 and the guide wheel 3 can rotate relative to each other; furthermore, the eccentric shaft 2 is fixed to the mounting base 1 by a fixing member 5. Specifically, the eccentric shaft 2 has a plurality of through holes 20, the mounting base 1 has a fixing hole, and the fixing member 5 passes through the through holes 20 and is connected to the fixing hole. By setting up an eccentric shaft 2, when the guide wheel 3 wears out during use, the fixing part 5 is loosened, making the eccentric shaft 2 loose. This allows the distance between the rotation center line of the eccentric shaft 2 and the center line of the guide wheel 3 to be adjusted by rotating the eccentric shaft 2, effectively adjusting the spacing of the guide wheel 3. This adjusted spacing compensates for the worn thickness of the guide wheel 3, greatly improving the utilization rate of the guide wheel 3, reducing the frequency of replacement, and lowering replacement costs. By setting up the fixing part 5, the through hole 20, and the fixing hole 13, when the eccentric shaft 2 rotates to a suitable position, the fixing part 13 passes through the through hole 20 and engages with the fixing hole 13 to fix the eccentric shaft 2. By setting up multiple through holes 20, when the eccentric shaft 2 rotates to different positions, the fixing part 5 can be inserted into the through hole 20 at different positions to fix the eccentric shaft 2 at different rotation positions.

[0026] Further, please refer to Figure 1 As shown, the mounting base 1 includes a base plate 11 and a pair of upright plates 12. The upright plates 12 stand on the base plate 11 and are spaced apart. The guide wheel 3 is placed between the pair of upright plates 12. Preferably, the base plate 11 and the pair of upright plates 12 are integrally formed. By placing the guide wheel 3 between the pair of upright plates 12, the overall structure can be made more compact, reducing the space occupied.

[0027] Further, please refer to Figure 2 and Figure 3As shown, the eccentric shaft 2 includes a support portion 21 and a connecting portion 22. The support portion 21 and the connecting portion 22 are integrally formed. The support portion 21 can be used to support the bearing 4. The opposing plate 12 has a through hole through which the support portion 21 can pass. In addition, each through hole 20 is provided on the connecting portion 22. By providing the through hole, the support portion 21 can be fixedly supported. By providing the through holes 20 on the connecting portion 22, when the support portion 21 drives the connecting portion 22 to rotate, the fixing member 5 can pass through the through holes 20 at different positions of the connecting portion 22 and connect with the fixing hole 13 to fix the support portion 21 at different positions.

[0028] Preferably, the connecting portion 22 and the supporting portion 21 are combined in a T-shape. By being configured in a T-shape, they can fit better with the mounting base 1. Of course, in this embodiment, the connecting portion 22 and the supporting portion 21 can also be combined in other shapes according to actual conditions and specific needs; this is not a unique limitation.

[0029] Further, please refer to Figure 2 and Figure 3 As shown, the connecting part 22 is circular, and the through holes 20 are distributed in a ring at intervals on the connecting part 22. In this way, when the supporting part 21 drives the connecting part 22 to rotate, the fixing member 5 passes through the through holes 20 at different positions and connects with the fixing hole 13, thereby fixing the supporting part 21 after it rotates to different positions.

[0030] Preferably, the fastener 5 is a bolt, and the fixing hole 13 is a threaded hole. In this way, a stable connection between the eccentric shaft 2 and the mounting base 1 can be achieved by the tight fixing of the bolt and the threaded hole.

[0031] Further, please refer to 2 and Figure 3 As shown, the connecting part 22 is also provided with a turning head 23 on the side opposite to the support part 21. By providing the turning head 23, when it is necessary to adjust the eccentric shaft 2, the fixing member 5 is loosened, so that the connecting part 22 and the support part 21 are in a loose state. Then, the turning head 23 is clamped with a wrench, so that it is easy to turn it with force. Preferably, the turning head 23 is square. Of course, it can also be other shapes, which are not limited here.

[0032] Further, referring to Figure 2, the eccentric shaft 2 has a first flow channel 24 and a second flow channel 25, which are connected. Specifically, the first flow channel 24 is perpendicular to the second flow channel 25. By providing the first flow channel 24 and the second flow channel 25, external lubricant can be guided to the bearing 4 for lubrication, thereby improving the service life of the bearing 4.
