[0039] Working principle: when it is necessary to automatically load and mark the packaging bags, first place the stacked packaging bags between the two limit plates 13, and adjust the position of the sliding block 12 so that the two limit plates 13 can limit the movement of the packaging bags, and then adjust the sliding block 23 to make the distance between the two limit strips 24 consistent with the side length of the packaging bags to prevent the packaging bags from running around on the conveyor belt 1, and then rotate the adjusting bolt 17 and the adjusting bolt 22 to make the pressure plate 15 press the packaging bags so that the bottom packaging bags can better fit with the push belt 26, and then start the motor 30 to drive the active pulley 28 to rotate, so that the push belt 26 drives the bottom packaging bags to be transported between the pressure wheel 10 and the conveyor belt 1, and the tension is released by the spring 9 to press the packaging bags, and the moving conveyor belt 1 transports the packaging bags to the bottom of the marker 3 for marking, thereby repeatedly circulating the above steps, so that multiple packaging bags are automatically moved to the bottom of the marker 3 for marking, thereby improving the marking efficiency.

[0040] Dust and harmful substances will be generated during marking. By starting the vacuum cleaner 31, the dust and harmful substances will be sucked in through the vacuum pipe 32, and then filtered through the filter plate 34 when discharged, thereby improving the environment around the equipment. When it is necessary to clean or replace the filter plate 34, first pull the handle 42 to drive the pull rod 39 to move, so that the block 38 is pulled out of the slot 36, so that the filter plate 34 loses its fixation, and the filter plate 34 can be pulled out by the handle 35 for cleaning or replacement. When installing a new filter plate 34 or the filter plate 34 after cleaning, first pull the handle 42 to make the block 38 enter the limit slot 37, and then install the filter plate 34 to the original position, release the force on the handle 42, and the spring three 40 releases the tension to clamp the block 38 into the slot 36, and the installation can be completed, thereby improving the efficiency of replacing the filter plate 34.
