A bag stacking guide groove is arranged on the bag discharging platform 1. A bag stacking station and a bag discharging station are arranged along the bag stacking guide groove on the bag discharging platform 1. When the device is used in conjunction with packaging bag processing equipment, the bag discharging platform 1 is arranged at the discharging place of the packaging bag processing equipment, and the packaging bag processing equipment is located at the bag stacking station of the bag discharging platform 1. The length direction of the bag stacking guide groove is consistent with the discharging direction of the packaging bag processing equipment. The packaging bag processing equipment outputs the packaging bags to the bag discharging platform 1 and the packaging bags are stacked along the bag stacking guide groove. The bag discharging station is used to install a discharging mechanism 7. The discharging mechanism 7 turns out the packaging stacked along the length direction of the bag stacking guide groove on the bag discharging platform 1 to realize discharging.

[0025] The counting and discharging mechanism is used to count the packaging bags outputted from the packaging bag processing equipment to the bag discharging platform 1, and transfer the counted packaging bags to the bag discharging station along the bag stacking guide groove. The counting and discharging mechanism includes a first counting mechanism 2, a second counting mechanism 3 and a bag pushing mechanism 4. After the packaging bag processing equipment outputs the packaging bags to the bag discharging platform 1, the packaging bags are stacked along the bag stacking guide groove, the first counting mechanism 2 counts the packaging bags stacked on the bag discharging platform 1, and after a certain amount of packaging bags are stacked, the bag pushing mechanism 4 cooperates with the first counting mechanism 2 to clamp the counted packaging bags, the packaging bag processing equipment continuously outputs the packaging bags, and the second counting mechanism 3 counts the packaging bags stacked on the bag discharging platform 1.

[0026] This embodiment adopts two sets of counting mechanisms. The function of the first counting mechanism 2 is to count the packaging bags on the bag discharge platform 1 and cooperate with the bag pushing mechanism 4 to transfer the counted packaging bags. The function of the second counting mechanism 3 is to replace the first counting mechanism 2 to count when the first counting mechanism 2 cooperates with the bag pushing mechanism 4 to transfer the packaging bags, so as to realize non-stop production of the packaging bag processing equipment.

[0027] The first counting mechanism 2 includes a first counting driver 21 and a first bag-blocking member 22. The first counting driver 21 drives the first bag-blocking member 22 to move along the bag stacking guide groove. Driven by the first counting driver 21, the first bag-blocking member 22 moves back and forth between the bag stacking station and the bag discharging station. When the first bag-blocking member 22 is at the bag stacking station, the first bag-blocking member 22 is driven by the first counting driver 21 to move along the bag stacking guide groove for counting. The bag-blocking portion of the first bag-blocking member 22 is on the bag discharging platform 1 to contact the packaging bag. The first counting driver 21 is preferably a high-precision servo module.

[0030] The bag pushing mechanism 4 is arranged between the first bag blocking member 22 and the second bag blocking member 33, and the bag pushing mechanism 4 includes a bag pushing driving member 41 and a bag pushing member 43. The bag pushing driving member 41 drives the bag pushing member 43 to move back and forth along the bag stacking guide groove. Driven by the bag pushing driving member 41, the bag pushing member 43 can cooperate with the first bag blocking plate to clamp the packaging bags counted by the first counting mechanism 2 on the bag outlet platform 1.

When the bag pushing member 43 is in the bag pushing clamping position, the bag pushing part of the bag pushing member 43 is located on the bag discharging platform 1, and the bag pushing member 43 moves along the bag stacking guide groove and can contact the packaging bag on the bag discharging platform 1. At this time, the bag pushing mechanism 4 can cooperate with the first bag blocking plate to clamp the packaging bag, and can move synchronously with the first bag blocking plate along the bag stacking guide groove to transfer the packaging bag to the bag discharging station; when the bag pushing member 43 is in the bag pushing avoidance position, the bag pushing part of the bag pushing member 43 is located on the side or below the bag discharging platform 1, and the packaging bag output by the packaging bag processing equipment does not contact the bag pushing member 43.

When the bag-pushing member 43 is in the bag-pushing clamping position, the baffle plate of the bag-pushing member 43 rises and part of the plate surface is above the bag-discharging platform 1. When the bag-pushing member 43 is in the bag-pushing avoidance position, the baffle plate of the bag-pushing member 43 completely falls below the bag-discharging platform 1. The second bag-blocking member 33 moves up and down between the bag-blocking counting position and the bag-blocking avoidance position. When the second bag-blocking member 33 is in the bag-blocking counting position, the baffle plate of the second bag-blocking member 33 rises and part of the plate surface is above the bag-discharging platform 1.

As the packaging bag processing equipment continuously outputs the packaging bags to the bag outlet platform 1, the first counting driving member 21 drives the first bag blocking plate to move continuously, and the packaging bags are counted according to the change in the movement amount of the first bag blocking plate. When the first bag blocking plate moves a specified distance, it indicates that the bag outlet platform 1 is full. A specified amount of packaging bags are stacked on the platform. At this time, the slide 51 moves from the standby position to the working position and drives the bag pushing member 43 in the bag pushing and clamping position to cooperate with the first bag blocking plate to clamp the measured packaging bags.
