Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper bag making, in particular to a vertical hot and cold packaging mechanism. Background Art

[0002] A kraft paper bag is a bag-like structure with an opening formed by a bottom wall and a peripheral wall. The bottom wall and the peripheral wall are made of multiple layers of paper material, generally including a bottom layer of kraft paper, a middle layer of honeycomb paper, and a top layer of kraft paper stacked in sequence from bottom to top. When stacked, they are pre-fixed by spraying glue to form a three-layer paper tape. Before the paper tape is cut to form multiple independent paper bags, the paper tape needs to be packaged (sealed) at least twice: (1) transverse packaging, which refers to acting on the paper tape along the width direction to form a first edge seal. The first edge seal is the same length as the width of the paper tape and is arranged at equal intervals along the length direction of the paper tape. In the subsequent cutting process, the cutting device acts on the aforementioned first edge seal to form multiple independent paper bags; (2) lateral packaging, which refers to acting on the paper tape along the length direction to form two second edge seals. The length of the second edge seal is the distance between two adjacent aforementioned first edge seals.

[0003] In the prior art, a (cold or hot) sealing wheel is used to roll along the width direction of the paper tape during transverse packaging, and a (cold or hot) sealing wheel is used to roll along the length direction of the paper tape during lateral packaging. This packaging method has the following disadvantages: (1) Bubbles are easily generated on the surface of the paper tape: during heat sealing, moisture on the surface of the paper tape or in the air is converted into gas when heated, and the gas easily enters the sandwich structure, resulting in the formation of bubbles on the surface of the paper tape; during transverse packaging, since the side edges have not yet been sealed, the gas generated in this step can be discharged from the side edges; during lateral packaging, the paper tape is divided into the front and rear paper tapes by the axis of the heat sealing wheel. After being acted upon (contacted) by the heat sealing wheel, the side edge of the front paper tape is already in a sealed state, and the front paper tape is Since the horizontal side has been sealed into a first edge seal and the lateral side is an uninterrupted second edge seal, bubbles are mainly generated during lateral sealing; (2) It is easy to cause line blockage: Although cold sealing can be used to reduce the above-mentioned defects caused by bubbles, the edge sealing quality of cold sealing is far inferior to that of hot sealing, and whether it is cold sealing or hot sealing, there is material extrusion. The packaging mechanism is provided with a conveying device acting on the bottom surface of the paper tape, and during lateral edge sealing, the sealing wheel always presses the side of the paper tape tightly. Although the sealing wheel and the paper tape are rolling in coordination, there is still friction opposite to the force of the conveying device, as well as speed difference. The above two factors continue to accumulate with the conveying length of the paper tape, resulting in material extrusion and line blockage. Utility Model Content
