Technical Field

[0001] The utility model relates to the technical field of carton packaging and printing, in particular to a positioning and conveying mechanism for carton packaging and printing. Background Art

[0002] During the printing process, cartons undergo a series of transport processes. Typically, cartons are transported by belt conveyors or other transport devices to the printing press area, where the graphics and text are printed. During this process, the position, angle, and alignment of the cartons directly determine the printing quality. Therefore, the accuracy and efficiency of the transport and positioning devices are particularly important.

[0003] However, during the transportation process, cartons often deviate from the correct conveying track or position due to transportation vibration or irregular operation and placement. Manual adjustment is required before printing to ensure the alignment of the cartons. The alignment and adjustment process is not only time-consuming and labor-intensive, but also greatly increases the intensity of manual work and affects the accuracy of printing.

[0025] Specifically, if Figure 1 and Figure 2As shown, when the carton packaging box conveyed on the belt conveyor 22 comes between the correction plates 23, the cylinder 4 starts to drive the piston rod 3 to extend, so that the angle of the push arm 7 at the bottom of the turntable 2 is relatively flipped, and the push arm 7 rotates along the hinge point with the fixed rod 8. Under the push of the connecting rod 9, the two groups of movable seats 10 move relatively horizontally, and the two groups of correction plates 23 position and correct the cartons from both sides, thereby twisting the manually swung cartons to the correct position, and driving the cartons to the center position of the belt conveyor 22, which is convenient for subsequent machine sealing.
