Both ends of the roller 200 are rotatably coupled to the frame 100, and the plurality of rollers 200 are disposed parallel to each other in a horizontal direction. The three sets of conveyor belt assemblies 300 are arranged in parallel with each other, the conveying direction of the conveyor belt assemblies 300 is parallel to the conveying direction of the rollers 200, and the three sets of conveyor belt assemblies 300 are respectively positioned at two sides of the frame 100 and in gaps formed by the plurality of rollers 200. The lifting assembly 400 is located below the conveyor belt assembly 300, and the lifting assembly 400 can drive the three conveyor belt assemblies 300 to simultaneously lift or lower, wherein the conveying height of the conveyor belt assembly 300 is higher than that of the roller 200 when the conveyor belt assembly 300 is lifted, and the conveying height of the conveyor belt assembly 300 is lower than that of the roller 200 when the conveyor belt assembly 300 is lowered.
According to actual demand, when needs use this device to realize automatic packing, need guarantee to be located can not produce relative slip between clamp plate and the transport mechanism of below to avoid the bottom of clamp plate to produce the scratch damage. The three sets of conveyor belt assemblies 300 are lifted by the lifting assembly 400 so that the transmission height of the conveyor belt assemblies is higher than that of the rollers 200, the pressing plates are stacked on the conveyor belt assemblies 300 one by one, and then the pressing plates are conveyed into the packer forward by the conveyor belt to finish packing. If the automatic packer fails, the stacked pressing plates need to be taken down from the conveying mechanism and manually packed. To increase efficiency, the number of manual bales is minimized, and thus the thickness of the stacked platens is much greater than the thickness of the platens that are automatically baled, generally much greater than the load carrying capacity of the conveyor belt assembly 300. At this time, the three sets of conveyor belt assemblies 300 are lowered by the lifting assembly 400, so that the conveying height of the rollers 200 is higher than that of the conveyor belt assemblies 300, a pad is placed on the rollers 200, then the pressing plates are stacked on the pad one by one, after stacking, the pad and the pressing plates are reversely conveyed by the rollers 200, and then the pad and the pressing plates are detached from the conveying mechanism, and finally manual packing is completed.

The horizontal channel 442 supports the two ends of the main connecting rod 430, thereby improving the supporting capability of the conveyor belt assembly 300 and the safety and reliability of the conveyor belt assembly 300. That is, the weight of the stacked platens is transferred through the ends of the main connecting rod 430 to the horizontal channel 442 in the main support block 420, avoiding directly stressing the first hydraulic cylinder 410, thereby avoiding an unintended descent of the conveyor belt assembly 300. When it is desired to lower the conveyor belt assembly 300, the opposite is true.

The roller motor 700 can drive all the rollers 200 to rotate synchronously and at the same speed through the chain wheels 210 and the chains.
In practice, the height of the platens stacked to be packed remains constant due to the inlet height limitation of the automatic packing machine, and the same number of platens often have inconsistent thicknesses due to the different gaps between the platens, thus requiring the height of the entire frame 100 to be adjusted during or after stacking is completed. To achieve this function, the bi-directional lift conveyor further includes a scissor lift mechanism 800, the scissor lift mechanism 800 including a base 810, a scissor mechanism 820, and a second hydraulic cylinder 830.
