Description

TECHNICAL FIELD

[0001] The utility model relates to packing machine equipment technical field, concretely relates to a packing machine K forming device. BACKGROUND

[0002] The K forming device is a key component of a K type full paper packing machine, which is used for accurately shaping a paper sheet into a "K" shape. It usually includes a complex mechanical structure, such as a movable lower shaping mechanism and an upper shaping structure, equipped with extrusion devices, driving cylinders and other components. Through the coordinated operation of various components, the paper sheet is extruded, folded and shaped to ensure that the preliminary shape of the package meets the requirements, laying a foundation for subsequent processes such as spot ironing, heat sealing and adsorption material taking. The accuracy and reliability of the design directly affect the quality and production efficiency of the final packaging product.

[0003] A paper box forming mechanism is disclosed in CN110370722B, which includes a rack, a first edge folding device and a second edge folding device. The first edge folding device includes a first lower mold, a first upper mold and an upper folding paper piece. The upper folding paper piece includes an upper folding paper board, which is installed on a first upper mold seat that rises and falls. The first lower mold has a slot for inserting the upper folding paper board. The second edge folding device includes a second lower mold, a lower folding paper board piece that rises and falls, and a second upper mold. The lower folding paper piece includes a lower folding paper board. The second lower mold has a slot for lifting the lower folding paper board. The second upper mold is installed on a second upper mold seat that rises and falls. The invention uses the first edge folding device and the second edge folding device to fold the cardboard into a box body with a containing cavity, achieving automatic forming of the packaging box.

[0004] A paper box forming mechanism is disclosed in CN217198881U, which is a K type paper box forming die. The die plate has a forming groove, which is open on one side in the length direction as a feeding port. A paper supporting protrusion is arranged in the forming groove. The paper supporting protrusion is longitudinally arranged, and its cross section is trapezoidal or triangular. The paper supporting protrusion has a gap between the groove wall and the feeding port in the length direction. A material slot is arranged on the paper supporting protrusion, which is transversely arranged and communicates with the forming groove. The depth of the forming groove and the height of the paper supporting protrusion are matched with the thickness of the material. It is applied to an automatic production line to realize full-automatic packaging. This technology and the above-mentioned paper box forming mechanism can constitute a K forming device of a packaging machine. However, the K-shaped packaging box is prone to deviation during the pressing and setting process, causing the shape of the produced packaging box to deviate. In addition, due to the particularity of the "K" shape, the two ends of the paper card will be subjected to pressure during the pressing and setting process. The pressure during the pressing process will cause the two ends of the paper card to be damaged, affecting the production of K-shaped packaging boxes. Therefore, there is still room for improvement in this technology. Summary of the Invention
