Description

Packaging carton and packaging method thereof

Technical Field

The invention relates to the technical field of case structures, in particular to a packaging carton and a packaging method thereof.

Background

Cartons, which are the most widely used packaging products, are corrugated cartons, single layer cartons, and the like, depending on the material. The common carton comprises three layers and five layers, wherein each layer is divided into inner paper, corrugated paper, core paper and surface paper, the inner paper and the surface paper are tea board paper and kraft paper, and the core paper is corrugated paper.

In some processing plants, the produced metal parts are often packaged in cartons for reducing the cost, and because the number of the metal parts is large and the weight of the metal parts is heavy, a plurality of metal parts are sometimes wound by plastic films to form a lump and then placed in the cartons. However, in the common carton, four paper boards at the edge of the opening of the bottom of the carton are overlapped to seal the bottom of the carton, and then the adhesive tape is used for sealing a gap generated by overlapping the paper boards, so that the bottom of the carton is sealed, and the mode of sealing the opening of the carton is the same as the mode of sealing the bottom of the carton. Because the mass of the metal parts is large, the bottom of the carton is only sealed by four paper plates at the edges after being overlapped and sealed, and the bottom of the carton is sealed by adhesive tape. Therefore, when the weight of the metal parts put into the carton is larger than the adhesive force between the adhesive tape at the bottom of the carton and the carton, the metal parts can cause the adhesive tape to be separated from the carton, so that the bottom of the carton is difficult to put into a product with larger quality, the containing effect of the carton is reduced, the adhesive tape with a larger quantity needs to be adhered at the bottom of the carton, the adhesive force between the adhesive tape and the carton is larger than the weight of the metal parts, and the capacity of containing the product in the whole carton is improved.

In addition, because metal parts are stacked in the carton through mutual stacking, in the transportation process, the situation of dislocation or inclination is inevitable to the adjacent parts from top to bottom, so that the gravity center of the whole metal parts inclines towards a certain side due to the situation of inclination or dislocation, the metal on a certain inner side surface of the carton damages the surface of the carton due to the large bearing pressure, and the deformation of the surface of the carton is caused, so that the carton is damaged or the carton cannot be normally put into products.

9. The method of packaging cartons according to any one of claims 1 to 8, wherein: the method comprises the following steps:

the first step is as follows: sealing the bottom of the carton: unfolding a paper box barrel in a folded state, placing the bottom of the paper box barrel upwards, then folding reinforcing strips on two opposite sides of the paper box barrel, folding one main bottom plate of the paper box barrel, then enabling corresponding auxiliary bottom plates, attaching plates and cover plates to penetrate through gaps between two same reinforcing strips of the paper box barrel, installing the main bottom plate, the auxiliary bottom plates, the attaching plates and the cover plates on the other side in a folding mode, then aligning the whole paper box, then folding the auxiliary bottom plates towards a connecting point between the main bottom plate and the paper box barrel, wherein the main bottom plate and the auxiliary bottom plates are close to the same side, and the auxiliary bottom plates are abutted to the opposite and overlapped reinforcing strips;

the second step is that: strengthening the strength of the inner wall of the paper box cylinder: the joint plate is turned upwards around the crease position between the joint plate and the auxiliary bottom plate, so that the joint plate covers the corresponding reinforcing structure on the inner wall of the carton cylinder, and the wall thickness of the carton cylinder is thickened;

the third step: perfecting and installing the reinforcing structure: the two sliding blocks of the first sliding piece are respectively connected with the two sliding rails of the same reinforcing structure in a sliding mode, then the threaded head of the connecting rod is connected with the threaded hole in a threaded mode, then the two sliding blocks of the other sliding piece are respectively connected with the two sliding rails of the same reinforcing structure in a sliding mode until the reinforcing rod is abutted against the connecting rod, meanwhile, the threaded hole of the reinforcing rod is opposite to the connecting hole of the connecting rod, and then the reinforcing rod is in threaded connection with the opposite threaded hole and the connecting hole through the connecting bolt so as to reinforce the inner wall of the;

the fourth step: further perfecting the strength of the inner wall of the reinforced paper box cylinder: after the main bottom plate, the auxiliary bottom plate and the attaching plate are folded and installed, the opposite openings form slots for the reinforcing structures to pass through, the clamping plates are inserted into the slots and cover the reinforcing structures, and the clamping plates are located between the attaching plate and the reinforcing structures;

the fifth step: further strengthen carton appearance intensity: putting the paper box into a sinking groove of a supporting base in advance, and enabling the anti-skid threads on the outer peripheral surface of the paper box to be mutually abutted with the rubber layer on the inner peripheral surface of the sinking groove;

and a sixth step: put into sealed case mouth behind the product to the carton: two apron are turned over around the crease direction, and two apron ends butt each other tentatively seal the case mouth, then turn over two shroudings around the crease direction, and two shrouding ends butt each other further seal the case mouth, utilize the sticky tape to splice with two shroudings simultaneously.
