[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an eccentric guide wheel shaft structure, including a mounting plate 1 and an eccentric shaft 3. Two sets of support shaft seats 2 are mounted on the upper end of the mounting plate 1. A first bearing 4 is installed through one end of each set of support shaft seats 2. An adjusting plate 7 is provided on one side of one set of support shaft seats 2. An arc-shaped adjusting hole 9 is opened through one end of the adjusting plate 7. A threaded hole 10 is opened through one set of support shaft seats 2. A bolt 11 is provided on one end of the adjusting plate 7. The inner wall of the adjusting plate 7 is fixed to the outer wall of the eccentric shaft 3. The inner walls of the two sets of first bearings 4 are fixed to the outer wall of the eccentric shaft 3. A part of the bolt 11 passes through the interior of the arc-shaped adjusting hole 9 and is threadedly connected to the threaded hole 10. A second bearing 5 is installed on the outer wall of the eccentric shaft 3. A guide wheel body 6 is installed on the outer wall of the second bearing 5.

[0023] The specific settings and functions of this embodiment are described in detail below. The mounting plate 1 serves as the basic load-bearing component of the entire structure and is used to install and fix the guide wheel shaft structure onto the main body of the equipment. Two sets of support shaft seats 2 are symmetrically installed on the upper end of the mounting plate 1, serving as the support structure for the eccentric shaft 3 and providing stable rotational support for the eccentric shaft 3. The eccentric shaft 3 is a core functional component, and its axis has a preset offset from the mounting section. The position of the guide wheel can be adjusted by rotation.

[0024] The first bearing 4 is installed through one end of the two sets of support shaft seats 2. Its inner wall is fixedly connected to the outer wall of the eccentric shaft 3, so as to realize the flexible rotation of the eccentric shaft 3 on the support shaft seat 2. The second bearing 5 is installed on the outer wall of the eccentric shaft 3 to support the guide wheel body 6 and ensure its smooth rotation. The guide wheel body 6 is installed on the outer wall of the second bearing 5 and realizes the guiding function by cooperating with the guide rail.

[0025] The adjusting disc 7 is located on one side of one of the support shaft seats 2. Its inner wall is fixedly connected to the outer wall of the eccentric shaft 3 and rotates synchronously with the eccentric shaft 3. The arc-shaped adjusting hole 9 is opened through one end of the adjusting disc 7 to provide room for the rotation of the adjusting disc 7. The threaded hole 10 is opened on the corresponding support shaft seat 2 and is used to lock and fix with the bolt 11. A part of the bolt 11 passes through the inside of the arc-shaped adjusting hole 9 and is threadedly connected with the threaded hole 10 to achieve locking and fixing after adjustment.

[0026] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a long block 8 is installed on the upper end of one set of support shaft seats 2, an arc-shaped scale plate 12 is fixedly installed on one end of the adjustment disk 7, and a pointer 13 is fixedly installed on one end of the long block 8. One end of the pointer 13 is in contact with one end of the adjustment disk 7.

[0027] The overall effect of this embodiment is that the long block 8 is installed on the upper end of one of the support shaft seats 2 as the mounting base of the pointer 13, the arc-shaped scale plate 12 is fixedly installed on one end of the adjustment disk 7 and rotates synchronously with the adjustment disk 7, and the pointer 13 is fixedly installed on one end of the long block 8, with one end in contact with one end of the adjustment disk 7, for indicating the adjustment angle.

[0028] The usage method and working principle of this device are as follows: First, there is a preset axial offset between the mounting section (the part that mates with the No. 1 bearing 4) and the working section (the part that mates with the No. 2 bearing 5 and the guide wheel body 6) of the eccentric shaft 3. When the eccentric shaft 3 rotates around the axis of its mounting section, the axis of the working section will make a circular motion with the axis of the mounting section as the center, thereby causing the guide wheel body 6, which is mounted on the working section, to shift its position.

[0029] Then, when it is necessary to adjust the position of the guide wheel body 6, first loosen the bolt 11, release the fixed constraint between the adjusting plate 7 and the support shaft seat 2, and rotate the adjusting plate 7 (by tool or direct operation). Since the adjusting plate 7 is fixedly connected to the eccentric shaft 3, it will synchronously drive the eccentric shaft 3 to rotate around the inner ring of the first bearing 4.

[0030] As the eccentric shaft 3 rotates, the axis of its working section shifts, which drives the guide wheel body 6 to generate radial displacement through the second bearing 5, thereby adjusting the gap between it and the mating guide rail.

[0031] During the adjustment process, the arc-shaped scale plate 12 fixed on the adjustment plate 7 rotates synchronously with the adjustment plate 7, while the pointer 13 fixed on the support shaft seat 2 remains stationary. By pointing the pointer 13 to different scale values ​​on the arc-shaped scale plate 12, the operator can accurately grasp the rotation angle of the eccentric shaft 3, and then calculate the displacement of the guide wheel body 6 to achieve quantitative adjustment.

[0032] After the guide wheel body 6 is adjusted to the target position, tighten the bolt 11 so that the head of the bolt 11 presses against the adjusting plate 7. The adjusting plate 7 is firmly fixed to the support shaft seat 2 by friction. At this time, the eccentric shaft 3 fixed to the adjusting plate 7 can no longer rotate, and its working section is kept in a specific position, so that the guide wheel body 6 is stably maintained in the adjusted position.

[0033] Finally, when the equipment is running, the guide wheel body 6 contacts the guide rail and rolls relative to it. The second bearing 5 ensures that this rolling process is smooth and without jamming. At this time, the locking mechanism (the cooperation of bolt 11, adjusting plate 7 and support shaft seat 2) bears the lateral force transmitted by the guide wheel and prevents the eccentric shaft 3 from rotating unexpectedly through sufficient friction torque, ensuring the stability of the guide wheel position and ensuring the smoothness and accuracy of the equipment operation.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
