The conveyor belt 3 is sleeved on the transmission shaft and the movement of the conveyor belt 2 is realized by the rotation of the transmission rod 18.

[0034] As described in the previous paragraph, the sliding block and transmission wheel on the transmission rod and their connection method are set to ensure that the conveying mechanism can still rotate during the movement, so that the conveying mechanism can achieve transportation while adjusting the spacing.

[0035] Please continue to refer to the attached Figure 4 Specifically, a driving motor 17 is provided at the lower end of any one of the conveying racks 2 , and another transmission wheel that maintains power transmission with the transmission wheel 20 is provided on the driving shaft of the driving motor 17 .

[0036] Furthermore, the transmission wheels may be connected via a transmission belt (such as a V-belt, a chain, etc.). For the convenience of illustration, the transmission belt is not shown in the drawings.

[0037] Specifically, the adjusting rod 14 is a threaded rod with opposite rotation directions at both ends. The conveying frames 2 of the two conveying mechanisms are respectively screwed together with the threads with different rotation directions at both ends. An operating handwheel 6 is provided at the outer end of the adjusting rod 14.

[0038] As described in the previous paragraph, the shape of the adjusting rod is set to facilitate driving the two conveying mechanisms to move in opposite directions during the rotation process, thereby achieving adjustment of the distance between the two conveying mechanisms.

[0039] Please see the attached Figure 1 -Attached Figure 3 Specifically, support plates 7 are provided on the two outer sides of the top of the frame 1 corresponding to the conveying direction of the conveying mechanism. A vertical strip hole is opened on the support plate 7 near the front end of the conveying mechanism. The clamping mechanism is movably installed in the strip hole to keep the height adjustable.

[0040] As described in the previous paragraph, the strip holes above the support plate are provided to facilitate the placement of the support rods. At the same time, the height of the support rods can be adjusted to facilitate the transportation of cardboards of different thicknesses.

[0041] Specifically, the clamping mechanism includes a support rod 8 that passes through the strip holes of the two support plates 7 and is fixed in the height direction by a fastener 9;
