After passing through the second swing rod, the connecting rod, the first swing rod, the first roller, and the box pressing adjustment plate, the box pressing rod is driven to turn forward clockwise to flatten the top surface of the opened packaging box;

[0018] S3 box feeding: the upper rocker arm drives the upper connecting rod to move downward under the action of the upper cam, and drives the compound feeding tooth plate to drop to the lowest point through the lifting rocker arm frame and the lifting seat. Then, the box feeding rocker arm assembly pulls the compound feeding tooth plate to slide backward under the action of the box feeding cam, so that the tooth notch at the rear end of the compound feeding tooth plate is just under the opened packaging box. Then, the upper rocker arm drives the upper connecting rod to move upward under the action of the upper cam, and then drives the compound feeding tooth plate to reset upward, inserting the opened packaging box into the tooth notch at the rear end of the compound feeding tooth plate. Finally, the box feeding rocker arm assembly drives the compound feeding tooth plate to slide forward under the action of the box feeding cam. This process is repeated to send the packaging boxes forward through the tooth notch of the compound feeding tooth plate in turn.

[0019] S4 folding BL and BR side ears: under the action of the side ear folding cam, the rear ear folding assembly folds the ear forward from the outside of the BL side ear during the horizontal box feeding process. At the same time, the rear ear guide plate folds the ear backward from the outside of the BR side ear.

[0020] S5 packaging box positioning: During the forward movement of the packaging box, the positioning link, under the action of the positioning cam, moves downward from the highest point to the lowest point, and drives the positioning adjustment seat to swing backward and lift from the bottom of the packaging box through the slider, push rod shaft, connecting plate, and curved arm until the positioning connecting plate is in a vertical state. The packaging box is positioned at the cartoning station, the front ear folding station, the lid folding station, the tongue folding station, and the tongue inserting station by using the positioning stop bars corresponding to the front long side of the packaging box; after the corresponding action is completed at the corresponding station, the positioning link, under the action of the positioning cam, moves upward from the lowest point to the highest point, and drives the positioning adjustment seat to swing forward from the bottom of the packaging box and descend to reset through the slider, push rod shaft, connecting plate, and curved arm;

[0021] S6 feeding (synchronized with S1-S5): the driving shaft pulley drives the material conveyor through the divider assembly to intermittently convey the material product or the product and lining combination to the push assembly;

[0022] S7 Pushing: When the material is conveyed to the pushing assembly, the pushing assembly pushes the material from the material conveyor horizontally into the packaging box with BL and BR side ears folded;

[0023] S8 folding the FL and FR side ears: During the subsequent box feeding process, the box feeding swing arm assembly, under the action of the box feeding cam, drives the composite feeding tooth plate to slide forward, so that the front ear folding device moves along the lifting seat, folding the FL side ear forward from the outside, and completing the FR side ear folding at the same time;

[0024] S9 pre-folding FC front cover and BC back cover: In the subsequent box delivery process, the FC front cover and BC back cover of the packaging box are pre-folded upwards and downwards respectively under the guidance of the guide strips;

[0025] S10 folds the FT front tongue and BT rear tongue: During the subsequent box feeding process, the FC front cover and BC rear cover of the packaging box are respectively guided by the lower guide block to the bottom of the front folding tongue strip and the top of the rear folding tongue strip. Then, the tongue-inserting connecting rod drives the tongue-inserting device under the action of the tongue-inserting cam to fold the corresponding FT front tongue along the lower edge of the front folding tongue strip and the upper edge of the rear folding tongue strip into the box;

[0026] S11 tongue insertion: During the subsequent box feeding process, the FC front cover and BC back cover of the packaging box are guided by the lower guide plate, and the tongue insertion connecting rod, under the action of the tongue insertion cam, drives the tongue insertion device to press against the FC front cover and BC back cover, inserting the corresponding FT front tongue along the inner top surface of the front packaging box and the BT back tongue along the inner bottom surface of the packaging box;

[0027] S12 Shaping: In the subsequent box feeding process, the packaging box is moved out from the front end of the composite feeding tooth plate and continues to be transported forward under the pushing action of the subsequent packaging box. The packaging box is shaped from the front and back sides. When the packaging box is conveyed to the rear pressing brush, the upper and lower sides of the packaging box are shaped.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention adopts a camshaft single-axis synchronous transmission mode in the main shaft power assembly. The reduction motor transmits power to various components through the camshaft via the first bevel gear, box suction cam, side folding ear cam, box feeding cam, positioning cam, tongue cam, etc., avoiding the defects of double-axis gear transmission such as tooth gap, low power transmission accuracy and poor synchronization. The power transmission is more direct and efficient, with better synchronization and stability, thereby improving the box loading efficiency.

[0030] 2. The present invention provides a positioning assembly that matches the main lifting assembly and the track assembly, adopts a movable structure driven by the main shaft, and realizes linkage with the positioning connecting plate, the crank arm and the main shaft power assembly connected by a pin shaft. The positioning block bar is not fixed to the track, so that the positioning block bar can be positioned movably, thereby playing a positioning role without affecting the movement of the packaging box, eliminating the gap between the packaging box and the compound feeding tooth plate, and realizing the precise positioning of the packaging box at the cartoning station, the front side ear folding station, the lid folding station, the tongue folding station, and the tongue inserting station, thereby ensuring the packaging quality and improving the packaging efficiency.

[0031] 3. The present invention provides a box pressing assembly linked to the box suction assembly.

During the box suction process, the box pressing rod first turns upward and backward counterclockwise to form a paper box downward path, and then presses the packaging box clockwise. The box pressing is carried out simultaneously with the box suction without affecting the operation of the packaging, thereby facilitating the transportation of the packaging boxes.

[0032] 4. The present invention provides a first sensor and a second sensor on the material conveying assembly, a third sensor on the carton rack assembly, and a fourth sensor on the over-material pressing assembly, thereby effectively avoiding empty boxes caused by leakage of materials (products or a combination of products and liner), damage to the pushing assembly due to protrusion of materials, and inability to load boxes due to lack of boxes in the carton rack assembly, thereby improving the operating efficiency of the entire machine, increasing the qualified rate of loading boxes, and avoiding waste;

[0033] 5. The present invention adopts box loading specification redundancy technology in the paper box material rack assembly, box suction assembly, rear folding ear assembly, track assembly, main lifting assembly, material overloading and box pressing assembly, and tongue assembly. By adjusting the corresponding precision limiting components in each component, the box loading requirements of materials with different specifications are met, and rapid production conversion is achieved.

The folding packaging box descends from the front end of the pressing box rod (612) and is placed on the rear ends of the front carton support strip (803) and the rear carton support strip (804); S2 box pressing: the box sucking swing rod (1503) drives the box sucking connecting rod (503) to move upward under the action of the box sucking cam (1512), thereby driving the optical axis (508) and the box pressing groove plate (511) to move upward synchronously, and then drives the box pressing rod (612) to turn forward clockwise through the second swing rod (607), the connecting rod (611), the first swing rod (606), the first roller (604), and the box pressing adjustment plate (610), thereby pressing the box pressing rod (612) to flatten the top surface of the opened packaging box; S3 box delivery: the top swing rod (1504) drives the top connecting rod (106) to move downward under the action of the top cam (1518), and drives the composite feeding tooth plate (105) to drop to the lowest point through the lifting swing arm frame (102) and the lifting seat (103). Then, the box delivery swing arm assembly (11) pulls the composite feeding tooth plate (105) to slide backward under the action of the box delivery cam (1519), so that the tooth notch at the rear end of the composite feeding tooth plate (105) is located just below the opened packaging box. The upper rocker arm (1504) drives the upper connecting rod (106) to move upward under the action of the upper cam (1518), thereby driving the composite feeding tooth plate (105) to reset upward, inserting the opened packaging box into the rear tooth notch of the composite feeding tooth plate (105), and finally, the box feeding rocker arm assembly (11) drives the composite feeding tooth plate (105) to slide forward under the action of the box feeding cam (1519), and so on, and the packaging boxes are sequentially fed forward from the tooth notch of the composite feeding tooth plate (105); S4 folding BL and BR side ears: under the action of the side ear folding cam (1513), the rear ear folding assembly (7) folds the ear forward from the outside of the BL side ear during the horizontal box feeding process, and at the same time, the rear guide ear plate (808) folds the ear backward from the outside of the BR side ear; S5 packaging box positioning: During the forward movement of the packaging box, the positioning link (916) moves downward from the highest point to the lowest point under the action of the positioning cam (1521), and drives the positioning adjustment seat (904) to swing backward and lift from the bottom of the packaging box through the slider (915), the push rod shaft (909), the connecting plate (908), and the crank arm (907) until the positioning connecting plate (903) is in a vertical state, and the packaging box is positioned at the boxing station, the front ear folding station, the cover folding station, the tongue folding station, and the tongue inserting station by using the positioning stop bar (906) corresponding to the front long side of the packaging box; after the corresponding station completes the corresponding action, the positioning link (916) moves upward from the lowest point to the highest point under the action of the positioning cam (1521), and drives the positioning adjustment seat (904) to swing forward from the bottom of the packaging box and descend and reset through the slider (915), the push rod shaft (909), the connecting plate (908), and the crank arm (907); S6 feeding: the driving shaft pulley (1517) drives the material conveyor (21) through the divider assembly (14) to intermittently convey the material to the push assembly (3); S7 Pushing: When the material is conveyed to the pushing assembly (3), the pushing assembly (3) pushes the material from the material conveyor (21) laterally into the packaging box with the BL and BR side ears folded; S8 folding the FL and FR side ears: In the subsequent box feeding process, the box feeding swing arm assembly (11) drives the composite feeding tooth plate (105) to slide forward under the action of the box feeding cam (1519), so that the front ear folding device (104) folds the ear forward from the outside of the FL side ear along the lifting seat (103), and the FR side ear folding is completed at the same time; S9 pre-folding the FC front cover and BC back cover: in the subsequent box delivery process, the FC front cover and BC back cover of the packaging box are pre-folded upwards and downwards respectively under the guidance of the guide bar (807); S10 folding the FT front tongue and the BT rear tongue: in the subsequent box feeding process, when the FC front cover and the BC rear cover of the packaging box are respectively moved to the bottom of the front folding tongue strip (811) and the top of the rear folding tongue strip (812) under the guidance of the lower guide block (809), the tongue insertion connecting rod (136) drives the tongue insertion device (131) under the action of the tongue insertion cam (1520) to fold the corresponding FT front tongue along the lower edge of the front folding tongue strip (811) and the upper edge of the rear folding tongue strip (812) into the box; S11 tongue insertion: In the subsequent box feeding process, the FC front cover and BC back cover of the packaging box are guided by the lower guide plate (813), and the tongue insertion connecting rod (136) drives the tongue insertion device to press against the FC front cover and BC back cover under the action of the tongue insertion cam (1520), so that the corresponding FT front tongue is inserted into the packaging box along the top surface of the front packaging box and the BT back tongue is inserted into the packaging box along the bottom surface of the packaging box; S12 Shaping: In the subsequent box feeding process, the packaging box is moved out from the front end of the composite feeding tooth plate (105) and continues to be fed forward under the pushing action of the subsequent packaging box, and the packaging box is shaped from the front and back sides. When the packaging box is fed to the rear pressing brush (815), the upper and lower sides of the packaging box are shaped.
