Background
Carton (english carton or hard paper case): the paper is a most widely applied packaging product, and comprises corrugated paper boxes, single-layer cardboard boxes and the like according to different materials, the paper has various specifications and models, the common paper boxes comprise three layers and five layers, seven layers are used less, each layer is divided into inner paper, corrugated paper, core paper and surface paper, the inner paper and the surface paper comprise tea board paper and kraft paper, the core paper is corrugated paper, the colors and handfeel of various kinds of paper are different, and the paper (the color and the handfeel) produced by different manufacturers are different. Are commonly used as a wrapper for goods or as an outer protective layer for goods.
After the goods that take out from the freezer are held to the holding in the cardboard case, frost on the cardboard case can produce the lime set with external contact, cause the cardboard case to wet from inside to it is difficult to in time to discover to begin to wet from inside, make the compressive capacity greatly reduced of cardboard case, cause the loss to the visitor, especially the corner of cardboard case, although vertical bearing capacity is stronger, but it is because buckling, lead to the structure to receive certain damage, the moisture easily infiltrates this department, lead to the cardboard case often to be followed the corner outward diffusion earlier and wet, thereby influence its intensity.
Disclosure of Invention
1. Technical problem to be solved
Aiming at the problems in the prior art, the invention aims to provide a waterproof reinforcement treatment process for carton corners, which can absorb moisture in a carton through a reinforcement corner lath arranged at the corner at the inner side of the carton, thereby effectively avoiding the condition that the strength of the carton from inside to outside is damaged due to the inward moisture, simultaneously, the reinforcement corner lath can effectively improve the longitudinal supporting force of the carton, so that a plurality of cartons are not easily damaged when being stacked together for goods transportation, in addition, after absorbing the moisture in the carton, effervescent tablet powder reacts with the water to generate gas and permeates into an outer sealing layer through a clamping net, so that the outer sealing layer expands, a bulge phenomenon is generated at the corner, when the moisture is larger, the moisture permeates into an inner moisture absorption cavity at the inner side along an inner water guide ball rod, so that the generated bulge is closer to the corner edge, thereby facilitating a worker to judge the moisture condition in the carton from the outer side, the abnormity of the carton can be conveniently found in time, and the loss of customers and merchants is reduced.
2. Technical scheme
In order to solve the above problems, the present invention adopts the following technical solutions.
A waterproof reinforcing treatment process for corners of a carton comprises the following steps:
s1, putting the reinforcing corner lath at the corner of the carton, and applying force to press the reinforcing corner lath to prick the edge of the reinforcing corner lath into the corner so as to temporarily position the reinforcing corner lath at the corner;
s2, performing hot air blowing on the outer side of the corner of the paperboard by using a hot air blower, so that the edge of the reinforcing corner batten is melted, and the inner wall of the corner of the paperboard is contacted;
s3, after the edges of the reinforcing angle plate are melted, the edges of the reinforcing angle plate penetrate into gaps formed at the corners of the carton, and an infiltration interlayer is formed between the reinforcing angle plate strips and the corners;
and S4, standing and cooling, wherein the reinforced corner lath is fixed at the corner after cooling, and waterproof reinforcing treatment at the corner is completed.
Further, reinforcement scute strip position is located the carton and is towards inboard corner, and the corner is the right angle, makes reinforcement scute strip be located the carton to be difficult for dropping and break away from, simultaneously can the moisture in the effective absorption case, effectively avoid causing the impaired condition of carton from inside to outside intensity to take place because of inside moisture, reinforcement angle lath can effectively improve the fore-and-aft holding power of carton simultaneously, makes a plurality of cartons stack and is difficult for being damaged when carrying out cargo transport together.
Furthermore, the temperature of hot air blown out by the hot air blower in the step S2 is 75-85 ℃, the carton is easily embrittled due to overhigh temperature to influence the strength of the carton, and meanwhile, the convex sticky strips can be softened at the temperature, on one hand, the binding force on the shrinkage rods is reduced, the carton is shrunk inwards, meanwhile, the softened convex sticky strips move towards the gaps formed in the carton, so that the connection strength between the softened convex sticky strips and the corners of the carton is remarkably improved, the strength of the formed exosmosis interlayer is remarkably improved, and the reinforcing angle plate strips are not easy to fall off.
