The other is connected to another transverse guide rail, so that a servo motor controls the positioning bag clamping assembly 81 on the two positioning lifting plates 83 to clamp the bag or release the bag, and another servo motor controls the mobile bag clamping assembly 82 connected to the transverse guide rail 84 to clamp the bag or release the bag. The frame 1 is also provided with a deflection shaft, and the eccentric shaft is connected to a transmission connecting rod 91 corresponding to the slide 85 one by one. The transmission connecting rod 91 is transmission-connected to the corresponding slide 85, and the deflection shaft 92 is driven by a transmission servo motor 93.

Once the compartments on the material conveyor belt 3 are aligned with the passage 62, the bags are simultaneously transferred from the bag opening station 5 to the bagging station 6 with their openings open. This ensures that the opened bag openings are aligned with the passage 62 and the poke rod 61. The poke rod 61 then pokes the large materials in the compartments directly into the bags along the passage 62 via the linear motion module 64.

[0027] Two side plates 71 are provided between the material conveyor belt 3 and the bag-carrying conveyor belt 2. A third guide rod 72 and an adjusting screw 73 are mounted in sequence between the two side plates 71. Two adjusting blocks are screwed onto the adjusting screw 73, and limit baffles 63 are mounted on the two adjusting blocks. The screw drive directions of the two adjusting blocks and the adjusting screw 73 are opposite, and the screw 51 and the third guide rod 72 form a passage 62. This allows for more reliable and smooth material bagging.

[0028] The bag-sealing station 30 comprises two stations, one upper and one lower, each driven by its own heat-sealing cylinder. The front station is integrated with the bag-closing station and features a vacuum cannula 80 on one side. This cannula 80 is mounted on a vacuum cylinder 800 and retracts. The cannula 80 is inserted into the bag, creating a vacuum while the upper and lower heat-sealing plates press against the bag opening to seal it. After the air in the bag is extracted, the upper and lower heat-sealing plates release the bag opening, and the rear station heat-seals the bag opening again. The upper and lower heat-sealing plates heat-seal the bag opening, then heat-seal the bag opening again. The two stations achieve a more reliable heat-sealing effect.

[0029] The rack 1 is also equipped with an automatic control system (PLC), which controls the various solenoid valves, motors, and servo motors, so that the cylinders can perform corresponding actions, and the suction cups 42 and clamping rods can complete adsorption and detachment functions, thereby enabling each workstation to automatically complete actions.

[0030] Its main working principle is: in the packaging bag conveyor clamp 8, the upper and lower clamping rods on the upper and lower positioning lifting plates 83 are used to clamp the packaging for station processing, and the upper and lower clamping rods on the slide board on the upper and lower transverse guide rails 84 are used to move the packaging bag from the upper station to the next station. Then the upper and lower clamping rods on the next station clamp the packaging bag sent over for station processing, and then the upper and lower clamping rods on the slide board release the packaging bag at the station and return to the previous station to continue receiving the packaging bag. After the packaging bag is output from the upper bag station, it is clamped by the upper and lower clamping rods on the slide board (movable bag clamping port The upper and lower clamps on both sides of the bag opening station (positioning bag clamping assembly 81) can be retracted to open the bag opening, and the bag in this state is transferred to the bag entry station to complete the horizontal side push bag entry of large materials. After bagging, the bag passes through the bag closing station, which also includes a bag sealing structure. After the bag opening is straightened and closed, the bag opening is vacuum-sealed and then passes through one or two heat sealing stations. After the bag is processed at the station, it can be moved out with the bag supporting conveyor.

[0031] By adopting the above technical solution, after the packaging bag is sucked and pulled out from the packaging bag discharge chute 41 by the suction cup 42 in the bag loading station 4, the bag body of the packaging bag is placed on the bag holding conveyor belt 2, and the bag opening of the packaging bag is sequentially operated through the bag opening station 5, the bag entering station 6, the bag closing station 7 and the bag sealing station 30 along the packaging bag station conveyor clamp 8. The material is placed in the grid bin on the material conveyor belt 3 and is input into the packaging bag through the bag entering station 6, thereby automatically bagging and packaging large-sized materials.
