[0026] Please refer to Figures 1-5 The utility model provides an embodiment: a stacking machine floating guide wheel device, including wheel frame 1, the inside installation of wheel frame 1 has guide wheel 3, and guide wheel 3 is used to contact with the stand of stacking machine, one side of wheel frame 1 is provided with mounting seat 2, mounting seat 2 is connected with wheel frame 1 through rotating adjusting mechanism, the middle position of the upper end surface of guide wheel 3 is provided with fixed plate 6, spring 8 is arranged between fixed plate 6 and mounting seat 2, and the both ends of spring 8 are fixed with fixed plate 6 and mounting seat 2 respectively;
[0027] When using, guide wheel 3 is arranged on wheel frame 1, wheel frame 1 is connected with mounting seat 2 through rotating adjusting mechanism simultaneously, and the connecting position of wheel frame 1 and mounting seat 2 has a gap, for the rotation of wheel frame 1, when the lifting mechanism of double stand stacking machine drives the vertical movement of loading platform, guide wheel 3 rolls on the stand surface of stacking machine, when the stand spacing is reduced, the stand extrudes guide wheel 3, at this moment, spring 8 is compressed, guide wheel 3 rotates around the pivot, realizes the reduction of the distance between guide wheel 3 and loading platform, thereby adapts the distance difference caused by the reduction of stand spacing, avoids the problem of loading platform jamming, when the stand spacing is enlarged, spring 8 is released, guide wheel 3 is still attached to the stand, and the stability of guiding movement is ensured.

[0029] Please refer to Figure 1The guide wheel mounting plate 4 is integrally formed with the wheel frame 1 through a bending device, which enhances the connection strength between the two and the stability of the overall structure. Compared with the traditional split design, integrally forming reduces the connecting parts and potential loose points, thereby improving the durability and reliability of the entire device. The integrally forming of the bending device with the wheel frame 1 ensures the precise position and angle of the guide wheel mounting plate 4, which is crucial for maintaining the correct contact and rolling between the guide wheel 3 and the upright column.
[0030] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the rotary adjusting mechanism includes a connecting plate 9, which is welded and fixed with the mounting seat 2. The inner side of the connecting plate 9 is fixedly installed with a second rotating shaft 10, one end of which extends to the inside of the wheel frame 1, and the second rotating shaft 10 is rotationally connected with the wheel frame 1. The wheel frame 1 and the mounting seat 2 are kept fixed gap through the connecting plate 9, realizing the rotary adjusting function of the wheel frame 1 relative to the mounting seat 2. This design enables the guide wheel 3 to adaptively adjust its position with the change of the upright column spacing of the double upright column stacker, thereby avoiding the problem of the loading platform being stuck due to the change of the upright column spacing.

The mounting seat 2 is fixed with the loading platform through the lock bolts 11, and a gasket is arranged between the lock bolts 11 and the mounting seat 2 to improve the fixing effect on the loading platform.
[0033] Further, the wheel frame 1, the mounting seat 2, the guide wheel mounting plate 4, the fixed plate 6, the reinforcing rib 7 and the connecting plate 9 are all made of stainless steel material. Stainless steel material is known for its high strength and excellent durability, and can withstand various stresses and loads generated during the operation of the stacker, ensuring long-term stable operation of the floating guide wheel device. The choice of this material effectively prolongs the service life of the equipment, reduces downtime and maintenance costs caused by component damage. The storage environment is often complex and variable, and may have adverse factors such as humidity and corrosive gases. Stainless steel material has excellent corrosion resistance and can maintain the integrity and stability of the structure in such harsh environments, preventing component failure or performance degradation caused by corrosion.
