[0002] The cartoning machine is a special equipment for loading articles into a packing box. In the traditional cartoning machine, the material is usually arranged on a conveying belt and pushed into the opened packing box by a pushing piece when the material is conveyed to the pushing station by the conveying belt, thereby completing the cartoning operation. The above structure can only be used for pushing and cartoning of fixed shape or single material. At present, a kind of stacked packing bag product on the market needs to be self-wound into a bundle before being loaded into the box when being cartoned because the packing box is small. The self-winding operation of such packing bag is currently operated by manual operation, and the labor intensity of workers is very large. After completing the self-winding, manual cartoning is also required. If the above conveying belt structure is used to convey the self-wound packing bag, the packing bag will be scattered and cannot maintain the self-wound bundle during the conveying process. SUMMARY

Specifically, the elastic member 9 is a spring. With the above structure, if the amount of material is large or the volume is large, when the material is rotated and formed in the forming space, the material squeezes and collides with the baffle, pushing the baffle to move a short distance, thereby preventing the material from getting stuck or damaged during the forming process due to insufficient space. After the forming process is completed, the spring will push the baffle to move to the appropriate position again.

The pushing drive mechanism can be a common linear drive structure such as a cylinder, a linear motor or a synchronous belt structure.

[0022] The working principle of the utility model is that the clamping rod 14 is first moved to a material taking station, clamps the stacked material (for example, stacked packaging bags), then the corresponding moving drive assembly drives the clamping rod 14 to move, the clamped material is transferred into the forming space surrounded by the baffles, at this time, the lower sealing plate 4 is in an open state, and part of the material is located outside the forming space, then the rotating disc 16 drives the clamping rod 14 and the material to rotate, the material is rotated and wound along the clamping rod 14 to form a bundle, so that the material can enter the forming space, then the lower sealing plate 4 acts to seal the bottom of the forming space, then the clamping rod 14 releases the material and exits from the forming space to separate from the material, the bottom of the material is supported by the lower sealing plate 4, and the remaining positions are limited by the baffles and cannot be deformed, finally, the front pushing block 2 acts to push the formed material out of the forming space and into the packaging box.
