The push plate 301 is connected to the lifting mechanism 302, and is used to drive the push plate 301 to rise so that the packaging bag can pass through, and to lower it to be placed on the side of the packaging bag; the push plate 301 is driven by the translation mechanism 303 to move along the length direction of the main frame 3, and is used to push the packaging bag along the table top of the main frame 3 to the pad 401 of the stacking unit 400 at the top of the vertical frame 2; the bag pressing mechanism 304 is arranged above the pad 401, and is used to flatten the top of the packaging bag; the lifting mechanism, the translation mechanism and the bag pressing mechanism are all connected to the controller.

Driven by the synchronous belt, the push plate can push the packaging bags one by one to the corresponding position on the pad.

[0044] In a specific embodiment of the present invention, Figure 5 , 6 As shown, the palletizing unit 400 includes a bag dropping mechanism 410, a tray locking structure 420 and a lifting component 402. The bag dropping mechanism 410 is arranged on the top of the vertical frame 2 and is used to drop the packaging bag onto the pallet 00. The pallet 00 is arranged on the lifting frame 401, and the lifting frame 401 limits the position of the pallet 00 through the pallet locking structure 420. The lifting frame 401 is connected to the lifting component 402, and the lifting component 402 is used to lift the pallet 00 supporting the packaging bag up and down. The bag dropping mechanism 410, the tray locking structure 420 and the lifting component 402 are all connected to the controller. Among them, the lifting component 402 adopts an electric lifting rod, the top of which is connected to the lifting frame, and the two sides of the lifting frame 401 are respectively connected to the two side frames on the opposite sides of the vertical frame 2 through the chain transmission mechanism 403. The packaging bags fall onto the pallet below through the bag dropping mechanism, and the electric lifting rod then drops to a certain height, waiting for the next group of packaging bags. This reciprocating process continues until the packaging bags are stacked to a certain height. The pallet locking structure releases the limit on the pallet, making it convenient to move the entire stack of packaging bags out of the vertical frame.

[0045] When designing specifically, Figure 7As shown, the bag dropping mechanism 410 includes a pad 411 and a telescopic component 412 connected to the controller, and the pad 411 is arranged above the tray; the pad 411 is a split structure, and the pad includes a first pad and a second pad, and four telescopic components 412 are respectively arranged at the four corners of the outer ends of the first pad and the second pad, and the telescopic components 412 are arranged inside the main frame 3.

In the specific production, the pad is made of stainless steel plate with a smooth surface and low friction; the telescopic component can achieve the telescopic function by using a cylinder, a hydraulic cylinder or an electric push rod. At the same time, a protective net 4 is provided above the telescopic component to avoid scratching the packaging bag.

[0046] As a preferred structure, Figure 5 , 8 As shown, the pallet locking structure 420 includes a mounting frame 421 and two pairs of lifting struts 422. The mounting frame 421 is connected to the lifting frame 401, and the four corners of the mounting frame 421 are matched with the slideways on the inner sides of the four corners of the vertical frame 2 through bearings 8; the two pairs of lifting struts 422 are arranged on opposite sides of the mounting frame 421; the lifting struts 422 include a telescopic rod 423 connected to the controller and a swing rod 424 at its end, the lower end of the swing rod 424 is rotatably connected to the middle support beam 425 of the mounting frame 421, the cylinder body of the telescopic rod 423 is rotatably connected to the frame of the mounting frame 421, the piston rod end of the telescopic rod 423 and the upper end of the swing rod 424 are both rotatably connected to the plug block 426, and the bottom of the pallet is provided with a limit groove that can be matched with the plug block 426. Among them, the telescopic rod can be a cylinder, a hydraulic cylinder or an electric push rod, all of which can realize its telescopic function. During the bag stacking process, the telescopic rod extends to insert the insert block into the bottom of the pallet to limit it, ensuring that the pallet remains stable during the bag falling process. When the pallet is full of bags and drops to the lowest point, the telescopic rod retracts to drive the insert block out of contact with the pallet, making it easier for the pallet to move out of the vertical frame.

[0047] In a specific embodiment of the present invention, Figure 1 , 2As shown, the wrapping unit 500 includes a slewing mechanism 510 for driving the tray 00 to rotate and a lifting column 501 for lifting and lowering a packaging film roll (not shown in the figure).

The lifting column 501 is arranged on the side of the slideway 512, and the packaging film roll moves up and down along the lifting column 501 through the height adjustment component 502. Among them, the height adjustment component can adopt chain drive, screw drive or other mechanisms, which can realize the linear lifting and lowering of the packaging film roll.

[0048] Further optimize the above scheme, such as Figure 1 , 2 As shown, a pair of guide blocks 503 are provided on one side of the lifting column 501 adjacent to the tray 00, and the packaging film can be arranged in the vertical gap between the two guide blocks 503. The pair of guide blocks are used to ensure that the packaging film is in a flat state during the process of wrapping the packaging bag. Fig.12 As shown, the guide block 503 is an annular frame composed of an outer arc edge and an inner and bottom straight edge; the lower ends of the two guide blocks 503 are adapted to mutually meshing gears 505, and the end of the wheel shaft of one of the gears 503 is fixed with a driving plate 506, and the edge of the driving plate 506 is hinged to the end of the piston rod of a hydraulic rod 507, and the cylinder of the hydraulic rod 507 is hinged to the base at the bottom of the lifting column. The hydraulic rod drives the gear to rotate, thereby forming a V-shaped opening above the two guide blocks, which is convenient for unfolding the packaging film and placing it in the gap between the two guide blocks, and then the hydraulic rod retracts to keep the opposite surfaces of the two guide blocks parallel.

[0049] In addition, a fuse mechanism 504 is provided on the side of the lifting column 501. The packaging film is wrapped around the outer periphery of the packaging bag after passing through the gap of the guide block 503. After the packaging film is wrapped twice from bottom to top and then from top to bottom, the fuse mechanism moves to the root of the packaging film around the pallet to fuse it.

Among them, a plurality of protrusions 11 that can push the pallet 00 are arranged at intervals on the chain 6 of the chain conveyor, and the chain 6 can drag the pallet 00 to run on the conveying track 5 driven by the motor 7; the conveying track 5 horizontally passes through the bottom of the vertical frame 2, and the conveying track 5 is arranged between the lifting components on both sides of the vertical frame 2, and can move the pallet 00 carrying the packaging bag out of the vertical frame 2.

[0051] The application process of the utility model is as follows:

[0052] The controller starts the electric lifting rod in advance to raise the tray to the highest position; the packaging bag is placed on the feeding conveyor and driven by the feeding conveyor to rise to the highest point and move to the belt conveyor in the gantry. The photoelectric switch in the gantry senses the packaging bag and sends a signal to the controller. The controller controls a pair of clamping arms to start clamping the packaging bag and turn the direction of the packaging bag according to the program pre-set by the controller, and then uses the belt conveyor to move the packaging bag to the push plate of the bag pushing unit. The controller starts the translation motor and drives the push plate to translate along the main frame, thereby pushing the packaging bag onto the pad.

[0053] The controller then starts the top pressing component to flatten the top surface of the packaging bag. After the pallet is fully stacked with a layer of packaging bags, the controller starts the four telescopic components at the same time, and the first pad and the second pad retreat at the same time, so that the packaging bags can fall onto the pallet below; then the electric lifting rod descends to a height, waiting for the next group of packaging bags, and stacking them back and forth until the packaging bags are stacked to a certain height.

[0054] When the bags on the pallet reach the required height, the controller starts the telescopic rod to retract to make the insert block detach from the pallet. After the pallet limit is released, the controller controls the chain conveyor to run, and the full pallet can be pushed out of the vertical frame using the empty pallet on the conveyor track. Then the telescopic rod is controlled to extend to insert the insert block into the limit slot of the empty pallet to complete the limit. The controller starts the electric lifting rod to the highest position to start a new round of palletizing.

[0055] The empty pallet moves along the conveyor track driven by the chain conveyor. When the pallet in the vertical frame is full, a new pallet can enter and push away the full pallet. The new pallet enters the lifting frame and is limited. It is raised to the highest position by the electric lifting rod to start a new round of palletizing. Driven by the chain conveyor, it moves to the packaging station, and the wrapping unit packs the stacked packaging bags. Then the chain conveyor transports the finished product stack to the designated location for easy forklift transportation.
