[0021] In order to further understand the features, technical means, and specific purposes and functions achieved by the present invention, the embodiments in this application and the features in the embodiments can be combined with each other without conflict. In order to further understand the features, technical means, and specific purposes and functions achieved by the present invention, and to analyze the advantages and spirit of the present invention, a further understanding is obtained through the following detailed description of the present invention in combination with the accompanying drawings and specific implementation methods.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "front", "rear" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0023] See attached Figure 1 As shown, attached Figure 1 The schematic structure of the present application is shown in the figure. The utility model includes a guide rail 12, which is installed on a frame 11. A sliding bearing block 13 is installed on the guide rail 12. The linear sliding bearing block 13 can drive the guide roller bracket 14, the slope guide roller 15 and other components installed thereon to move linearly along the guide rail 12.
[0024] The locking screws 17 are respectively arranged at two ends of the sliding bearing block 13 , and the top end of the locking screw 17 is arranged close to the guide rail 12 .
[0025] A shaft seat 23 is provided in the middle of the top surface of the linear sliding bearing block 13, on which a shaft core assembly 18 is mounted. A tripod 21 is provided on the shaft seat 23 and sleeved on the shaft core assembly 18. The shaft of the shaft core assembly 18 extends out of the shaft seat 23 and extends outside the shaft seat 23.
[0026] A fulcrum shaft hole 22 (shaft sleeve) is provided at the top corner of the tripod 21 below the guide roller bracket 14. The fulcrum shaft hole 22 is suitable for installation on the extension shaft of the shaft core assembly 18. The fulcrum shaft hole 22 allows the entire guide roller bracket 14 to rotate flexibly and freely around the axis of the shaft core assembly 18.
[0027] The retaining ring 19 is also installed on the shaft of the shaft core assembly 18. The retaining ring 19 is located outside the fulcrum shaft hole 22 (shaft sleeve). The retaining ring 19 is provided with a fixing pin, and the retaining ring 19 is fixed on the shaft of the shaft core assembly 18.
[0028] The slope guide roller 15 is installed between the side plates 24 at both ends of the guide roller bracket 14. The ends of the slope guide roller 15 are hinged to the side plates 24. The slope guide roller 15 adopts a slope design with large ends and a small middle. The slope guide roller 15 is a cylinder with an inwardly concave arc.
[0029] The two ends of the two precision tension springs 16 are respectively mounted on the swing arms at both ends of the guide roller bracket 14 and the two ends of the linear sliding bearing block 13 .
[0030] Compared with the prior art, the present application does not use a paper edge detection sensor, a controller, or an electric actuator, and completely solves the problem of substrate deviation correction through mechanical design.
[0031] Furthermore, in one of the embodiments of the present application, the device is installed on a 730 mm wide wallpaper printing production line. After the installation is completed, the paper is stretched taut on the slope guide roller 15, that is, the paper bypasses the slope guide roller 15 at a larger angle, so that there is sufficient pressure and friction between the paper and the slope guide roller 15.
[0032] The guide rail 12 is installed on the frame 11, and the sliding bearing block 13 is sleeved on the guide rail 12. The sliding bearing block 13 and the guide rail 12 are linearly slidably connected; when it is necessary to adjust the correction center point (the fulcrum shaft hole 22), the sliding bearing block 13 can be moved manually, and the sliding bearing block 13 drives the guide roller bracket 14, the slope guide roller 15 and other components installed thereon to move linearly along the guide rail 12. After moving to the appropriate position, tighten the locking screw 17 to make the sliding bearing block 13 pressed against the guide rail 12. At this time, the linear sliding bearing block 13 is fixed on the guide rail 12 and can no longer move linearly.
[0033] A rotating shaft seat 23 is installed in the middle position of the sliding bearing block 13, and an axis core assembly 18 perpendicular to the guide rail 12 is arranged on the rotating shaft seat 23. A tripod 21 is arranged on the axis core assembly 18, and a fulcrum shaft hole 22 at the top angle of the tripod 21 is hingedly connected to the axis core assembly 18.
[0034] A fulcrum shaft hole 22 is provided at the top corner of the tripod 21 below the guide roller bracket 14. The fulcrum shaft hole 22 is of a size suitable for installation on the shaft of the shaft core assembly 18. The entire guide roller bracket 14 can rotate flexibly and freely around the fulcrum shaft hole 22. The entire guide roller bracket 14 is based on the fulcrum shaft hole 22 at the top corner of the tripod 21. The tripod 21 is in the shape of an isosceles triangle and achieves symmetrical weight balance at both ends. Its characteristic is that the isosceles tripod 21 is similar to a balance with the fulcrum shaft hole 22 as the fulcrum.
[0035] The retaining ring 19 is also installed on the shaft core assembly 18, located on the outside of the fulcrum shaft hole 22, and the retaining ring 19 is provided with a fixing pin. The retaining ring 19 can be fixed on the shaft core assembly 18 to prevent the fulcrum shaft hole 22 of the guide roller bracket 14 and the entire guide roller bracket 14 from escaping from the shaft core assembly 18.
[0036] The slope guide roller 15 is installed on the guide roller bracket 14. The slope guide roller 15 adopts a slope design with large ends and a small middle, which can increase the effect of correcting deviation.
[0037] The two ends of the two precision tension springs 16 are respectively fixed to the swing arms at the two ends of the guide roller bracket 14 and the two ends of the sliding bearing block 13. With the support of the two precision tension springs 16, the guide roller bracket 14 and the slope guide roller 15 thereon can form a highly sensitive tension scale and reach a static balance state. At this time, the central axis of the slope guide roller 15 is in a horizontal state.
[0038] During operation, the paper bypasses the slope guide roller 15 at a large angle, and the paper exerts a certain amount of pressure and friction on the slope guide roller 15. When the paper does not deviate, the force exerted by the paper on the slope guide roller 15 is equal at both ends, and the guide roller bracket 14 and the two precision tension springs 16 are still in a dynamic balance state. However, when the paper deviates to the left, the force exerted by the paper on the left side of the slope guide roller 15 becomes larger, and the balance of the tension scale is broken. At this time, the entire guide roller bracket 14 with all its components tilts to the left, and the right side of the entire guide roller bracket 14 will rise. At this time, the paper follows the principle of deviating to the side that is higher, and will have a tendency to move toward the right side of the guide roller bracket 14. This tendency will disappear as the paper is re-centered, and vice versa.
[0039] The length D of the bottom side of the tripod 21 (isosceles triangle) is 1 / 2 to 2 / 3 of the length of the guide roller bracket 14. Preferably, the length D of the bottom side of the tripod 21 is 3 / 5 of the length of the bottom frame of the guide roller bracket 14. The top angle α of the tripod 21 is 70° to 80°, and the top angle α of the top of the fulcrum shaft hole 22 on the tripod 21 is preferably 75°.
