The bagging machine is a plastic bag bagging machine, and the plastic bag comprises a flat bag, a vest bag and the like. The plastic bags are generally automatically processed and produced by a bag making machine, and in order to be convenient for storage, transportation, sale and use, the plastic bags are generally folded for multiple times by a plastic bag folding and binding machine, finally folded into long strips and bound, and then the bound plastic bags are packed into a larger packaging bag (namely a nylon woven bag) in a bundle manner. In the past, the packing work is finished manually, and the problems of high labor intensity, low efficiency, irregular placement and the like exist. Application publication No.: CN110861795A discloses a bagging machine (hereinafter referred to as comparison document 1), which mainly includes: the automatic bag clamping machine comprises a rack, a conveying device, a mold frame device, a bag clamping mechanical arm and a mechanical arm moving device; the mould frame device on be equipped with flexible die-pin mechanism, flexible die-pin mechanism is a row bag mechanism, can discharge the plastic bag in the mould frame and push into in the packing bag. The comparison document 1 stacks the plastic bags in the die frame through the bag clamping mechanical arm, then the packaging bags are sleeved on the die frame, the die frame swings backwards to be in a transverse state, and then the plastic bags in the die frame are pushed into the packaging bags under the pushing of the bag arranging mechanism, so that the packaging work of the plastic bags is completed. There have also been many attempts at a bagging machine for packaging plastic bags: the mold frame is arranged on the frame, the mold frame is transversely arranged front and back, a bag filling opening is formed in the front end of the mold frame, a bag outlet is formed in the rear end of the mold frame, and the bag filling opening and the bag outlet of the mold frame are through and permeable front and back. The packaging bag is sleeved on the mold frame from the rear end of the mold frame in advance, and the bag bottom of the packaging bag is located at the bag outlet of the mold frame. The plastic bags are loaded into the mold frame from the bag loading opening, and the plastic bags in the mold frame are discharged into the packaging bags by the telescopic supporting rod or other bag arrangement mechanisms after the mold frame is filled. Whether it is the comparison document 1 or other prior arts, there are problems that: when the plastic bags are arranged into the packaging bags, firstly, the packaging is not compact enough and loose, and the packaging amount of each packaging bag is not large enough, for example, each packaging bag can contain 100 bundles of plastic bags when the packaging bags are manually packaged, and each packaging bag can only contain 80 bundles when the packaging bags are packaged by a machine; secondly, the packaging bag needs to be erected manually, which is labor-consuming and inconvenient for sealing and removing the packaging bag; and the packaging bag is in a front-back transverse state after being filled with the plastic bag, and the plastic bag is more easily rebounded and expanded in the transverse state, so that a plurality of plastic bags overflow from the bag opening of the packaging bag and fall off.

The supporting plate is a plate-shaped body, corresponds to the mould frame and is used for supporting the bag bottom of the packaging bag. As a preferred technical scheme, the supporting plate is an L-shaped plate and comprises a transverse plate and a vertical plate, and the vertical plate is erected at one end of the transverse plate to form an L-shaped structure. The vertical plate corresponds to the rear end of the die frame and is used for supporting the bag bottom of the packaging bag; the transverse plate corresponds to the lower side of the mold frame and is used for supporting the side face of the packaging bag. The transverse plate and the vertical plate are described by dividing the integrated supporting plate into two parts for easy understanding, and actually, a rectangular flat plate is bent into a right angle to form an L shape.

Preferably, the supporting plate moving mechanism is connected with a bracket, the supporting plate is connected with the bracket, and a swing cylinder is connected between the supporting plate and the bracket. For driving the pallet to swing back and forth relative to the carriage.
