Sealing device for left and right cover plates at rear ends of boxes in full-automatic stacking and box filling machine

Abstract

The invention discloses a sealing device for left and right cover plates at rear ends of boxes in a full-automatic stacking and box filling machine for packaging strip-shaped or box-shaped articles. The sealing device comprises a framework; a box conveying platform is arranged in the framework, a mounting support is arranged on the framework and is positioned on one side of the box conveying platform, a rotating cylinder and a cover pressing plate are sequentially arranged on the mounting support along a conveying direction of a distribution box, the rotating cylinder is vertically mounted on the mounting support, an oscillating rod is fixed onto a piston rod of the rotating cylinder, can be driven by the rotating cylinder to rotate and then can jack a left cover plate at the rear end of the distribution box, so that the left cover plate is turned inwardly; and the cover pressing plate is transversely arranged on the mounting support along the conveying direction of the distribution box, and the front end of the cover pressing plate can jack a right cover plate at the rear end of the distribution box when the distribution box moves along the box conveying platform to the location of the cover pressing plate, so that the right cover plate can be turned inwardly. The sealing device has the advantages that the work efficiency can be improved, the work intensity can be reduced, and the left cover plate and the right cover plate at the rear end of the distribution box can be automatically sealed inwardly.

Description

Technical field [0001] The invention relates to the field of packaging machinery, in particular to a sealing device for the left and right cover plates at the rear end of a box in a fully automatic palletizing and packing machine for packaging strip or box-shaped articles. Background technique [0002] At this stage, people generally use PE film heat shrink packaging machine to complete the packaging work when people ship strip or box objects such as cigarettes: by heating the PE film, the PE film will be attached to the article after the heat shrinks. On the other hand, PE film is difficult to be reused directly, and on the other hand, PE film is difficult to be reused directly at high temperature. Volatile toxic substances that are harmful to human health have laid hidden dangers for workers' safety in production. At present, people have produced a distribution box that can be recycled and reused, is safe and non-toxic, and can ship strip or box-shaped items. The production ma...

Problems solved by technology

[0002] At this stage, when people ship strip or box-like items such as cigarettes, PE film heat shrink packaging machines are generally used to complete the packaging work: by heating the PE film, the PE film is heated and shrunk and then attached to the item The surface of the stacked items is completed, and then the packaged items are transported; the disadvantages of the above packaging methods are: on the one hand, it is difficult to directly reuse the PE film, on the other hand, the PE film will be damaged at high temperature Volatilizes toxic substances that are not conducive to human health, burying hidden dangers for workers' safe production

At present, people have produced a distribution box that can be recycled repeatedly, is safe and non-toxic, and can ship strips or box-shaped items. The production material of this distribution box can be nylon, paper or plastic; in order to use For transportation and saving space, the distribution boxes are closed and pressed into flat shape before use. When people need to use it to deliver and load items, they need to stretch the flat distribution box into a box shape and place it on the packaging conveyor belt. The worker puts the items into the distribution box, then manually folds the left and right cover plates at the rear end of the distribution box inward, and then folds the upper and lower cover plates at the rear end of the distribution box inward, thus completing the four cover plates at the rear end of the distribution box. Sealing operation; this kind of operation method of manually folding and sealing the left and right cover plates at the rear end of the distribution box not only increases the labor intensity of workers, but also reduces work efficiency
