In addition, the technical features involved in each of the embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0016] As shown in Figures 1-3 A conveying lifting platform with automatic balance adjustment function, comprising a main frame, a photoelectric proximity switch 3 and two sets of lifting devices 2 symmetrically installed on both sides of the main frame, the shape of the main frame is not limited, as long as it can realize the setting of the side plate 1 on both sides for installing the lifting device 2, and the middle part is hollow, which can accommodate the paperboard, and the main frame is provided with a side plate 1 on both sides.
[0017] The lifting device 2 comprises a lifting motor 21, a lifting main sprocket 22, a double-row sprocket 23, and a paperboard supporting plate 24.

The lifting main sprocket 22 is provided with a rotating shaft on the side, and the rotating shaft is fixed on the side plate 1 through a bearing, and the rotating shaft is in a rotatable state. The lifting main sprocket 22 is arranged on the side plate 1 close to the lifting motor 21, so that the lifting motor 21 and the lifting main sprocket 22 are transmissionally connected through a chain, and the transmission distance is reduced. The rotating shaft is connected with the side plate 1 through a bearing, and the end thereof penetrates through the side plate 1, and the rotating shaft penetrating through the side plate 1 is provided with the double-row sprocket 23. The double-row sprocket 23 comprises a first sprocket and a second sprocket. The first sprocket is connected with the paperboard supporting plate 24 through a chain, and one end of the chain on the first sprocket is directly fixed on the paperboard supporting plate 24. The second sprocket is connected with the paperboard supporting plate 24 through a corner sprocket, and the corner sprocket and the double-row sprocket 23 are located on the same horizontal line of the side plate 1, so that the chain can be horizontally transmitted. An optical proximity switch 3 is arranged on the upper portion of the outer side of the paperboard supporting plate 24, that is, when the paperboard on the paperboard supporting plate 24 rotates from top to bottom, the optical proximity switch 3 is located on the outer side of the paperboard supporting plate 24 and does not overlap the paperboard supporting plate 24. The optical proximity switch 3 can be fixedly connected with the main frame through a mounting frame. Here, how the optical proximity switch 3 is installed is not limited, as long as it can be located on the outer side of the paperboard supporting plate 24, and the height thereof can be set according to the height required by the subsequent operation process, and can be set to be slightly higher than the height required by the subsequent operation process. The optical proximity switch 3 and the lifting motor 21 are electrically connected with a control device. The control device is not indicated in the figure, and is a prior art, which will not be described in detail here. Through cooperation with the control device, when one corner of the paperboard stack is sensed by the optical proximity switch 3, the control device controls the lifting motor 21 on the corresponding side to stop rotating; until the other optical proximity switch 3 also senses the other corner of the paperboard stack, the lifting motor 21 on the other side also stops rotating, at this time, the upper surface of the paperboard stack is flush with the pair of optical proximity switches 3, and the process is the automatic balancing adjustment process.

Through the connecting device, the skew of the paper supporting plate 24 can be buffered, the two crossing directions are allowed to shake to a certain extent, and the damage caused by the fixed connection in the prior art is avoided.
[0021] In order to avoid the serious skew of the paper supporting plate 24 caused by the large differential speed of the two lifting motors 21, and to avoid the serious skew of the paper supporting plate 24 caused by the failure of the photoelectric proximity switch 3, an inductive corner signal generator 5 is arranged on the shaft and passes through the side end, an inductive proximity switch 6 is arranged at a horizontal position opposite to the inductive corner signal generator 5, and the inductive corner signal generator 5 and the inductive proximity switch 6 are electrically connected with the control device. Through the cooperation of the inductive corner signal generator 5, the inductive proximity switch 6 and the control device, the maximum deviation of the corner of the lifting device 2 on both sides can be monitored by monitoring the rotation number of the inductive corner signal generator 5 on the shaft, the differential speed of the two lifting devices is avoided to be too large, and the skew of the paper supporting plate is avoided to be serious even in the case of the failure of the photoelectric proximity switch 3.
