The invention is characterized in that it further comprises a counting and conveying device which is mounted on the frame, the rear end of the counting and conveying device corresponding to a position below the front end of the arcuate paper feeding channel, and the conveying speed of the counting and conveying device is greater than the conveying speed of the box erecting conveying device.

[0007] The front and back directions are determined by the conveying direction of the paper box. The position where the paper box passes first is the front, and the position where the paper box passes later is the back. When the paper receiving and conveying mechanism conveys the paper box, the flat paper box is conveyed from the previous process to the counting and conveying device. The counting and conveying device quickly conveys the paper box to the vertical box conveying device and counts the number of paper boxes that pass through. During conveying, since the conveying speed of the counting and conveying device is greater than the conveying speed of the vertical box conveying device, when the paper box is transferred from the rear end of the counting and conveying device to the curved paper feeding channel, and only the rear part enters the curved paper feeding channel while the front part is still in a suspended state, the counting and conveying device can convey the new paper box into the curved paper feeding channel from the bottom, so that the adjacent paper boxes are partially overlapped. , effectively improving the transportation efficiency of the paper boxes, and because the rear end of the counting and conveying device is located below the front end of the arc-shaped paper feeding channel, the paper boxes fed in later can be conveyed from a low position to a high position, and thus inserted under the paper boxes fed in earlier, forming a specific orderly array in which the paper boxes fed in earlier always cover the paper boxes fed in later; at the same time, with this structure, when the subsequent paper boxes are transformed from a flat state to an upright state and are about to be sent out from the rear end of the arc-shaped paper feeding channel to the collection mechanism of the counting and box erecting machine, the paper boxes fed in later can pass through the overlapping part to support the paper boxes to be sent out, so that the paper boxes to be sent out can remain in an upright state to complete the transfer and collection.

Due to the overlapping portions between the paper boxes, the paper boxes periodically slightly lift various positions of the downward section of the upper conveyor belt assembly during the process of being conveyed along the curved paper feeding channel. By providing the elastic tensioning wheel assemblies, the downward section of the upper conveyor belt assembly can be caused to fluctuate and quickly recover when being lifted to accommodate the conveying of the paper boxes.

[0009] In a further preferred embodiment, the frame is provided with a mounting bracket extending along the length of the downstream section of the upper conveyor belt assembly; the elastic tensioning wheel assembly includes a tensioning wheel frame, a compression spring, and at least one first tensioning wheel; the upper end of the tensioning wheel frame is provided with a swing arm, one end of the swing arm is hinged to the frame, the compression spring is disposed between the other end of the swing arm and the mounting bracket, the lower end of the compression spring is connected above the other end of the swing arm, and the upper end of the compression spring is connected to the mounting bracket; the first tensioning wheel is rotatably mounted on the tensioning wheel frame, and the first tensioning wheels in each elastic tensioning wheel assembly are sequentially arranged along the length of the downstream section of the upper conveyor belt assembly. When the carton pushes the downstream section of the upper conveyor belt assembly, the first tensioning wheel, driven by the pushing of the downstream section, drives the tensioning wheel frame, thereby causing the swing arm to swing upward about the hinge point; the swing arm then swings downward again under the action of the compression spring, thereby pushing the tensioning wheel frame to reset.

Since the cartons need to be packed after a certain number of cartons are conveyed, the counting and conveying device will stop conveying after a certain number of cartons are reached. At this time, the upright box conveying device will quickly increase the conveying speed and quickly convey the remaining cartons in the curved paper feeding channel to the collection mechanism at one time to make up a batch of packing quantities; by dividing the upper conveyor belt group and the lower conveyor belt group into two sections, the last carton enters the second half of the curved paper feeding channel and is conveyed by the second and fourth circular belts. At this time, the counting and conveying device can be restarted and conveyed to the front half of the curved paper feeding channel.
