Glue-free packaging method and device enabling externally supplied packaging section and winding drum to be oppositely combined in pressed mode and winding drum

Abstract

The invention relates to a glue-free packaging method and device enabling an externally supplied packaging section and a winding drum to be oppositely combined in a pressed mode and the winding drum. The method includes the following steps of unreeling, conveying of the packaging section, opposite overlapping, first mechanical connection, reeling and second mechanical connection. The device comprises a packaging section conveying mechanism, and a traction device forming an opposite overlapping area is arranged in the output direction of the packaging section conveying mechanism. A first press-combining connection mechanism is arranged in the opposite overlapping area, and a second press-combining connection mechanism is arranged at the back of the first press-combining connection mechanism. The device further comprises a conveying mechanism. Glue is not needed for adhesion in the packaging process, use is more convenient, the use cost of glue is eliminated, and a product is healthier and environmentally friendlier. In addition, the conveyed packaging section can be made of materials identical with or different from those of the winding drum, and the processing procedures of printing, coining and the like can be conducted in the conveying process, so that products are more diverse.

Description

technical field [0001] The invention relates to a method and equipment for relative pressing and non-adhesive sealing of rolls in an external supply packaging section and the roll. Background technique [0002] The reel is a roll-shaped material formed by winding the web-shaped material, and the common forms are toilet paper rolls, plastic rolls, etc. Taking the toilet paper roll as an example, in order to maintain the stability of the roll during packaging and transportation, the existing roll needs to be sealed at the tail end of the roll so that it will not fall apart. The end of the reel is bonded with glue to maintain the stability of the reel, but when the user uses it, because the glue is bonded irreversibly, the user needs to tear the end from the reel, and the tearing process will destroy the end and the end. The outer ring of the reel that is glued to each other makes a part of the tail end unable to be used normally, and because the glue has a certain permeabilit...

AI Technical Summary

Problems solved by technology

Taking the toilet paper roll as an example, in order to maintain the stability of the roll during packaging and transportation, the existing roll needs to be sealed at the tail end of the roll so that it will not fall apart. The end of the reel is bonded with glue to maintain the stability of the reel, but when the user uses it, because the glue is bonded irreversibly, the user needs to tear the end from the reel, and the tearing process will destroy the end and the end. The outer ring of the reel that is glued to each other makes a part of the tail end unable to be used normally, and because the glue has a certain permeability, in some cases it tends to stick to the inner paper, causing the user to tear off multiple layers before using it, which not only wastes materials , and it is inconvenient to operate

[0003] Moreover, a large amount of glue will be used in the existing roll end sealing, which not only needs to increase the additional material cost, but also the glue is a kind of chemical synthetic material, which has certain harmful components and has certain volatility, whether it is In the production process or when used, it will have a negative impact on the health of workers or users, and the use of a large amount of glue is not conducive to environmental protection

[0004] In addition, there is a problem that the above-mentioned reels of the prior art can only use their own materials for sealing operations, and cannot solve the problem of sealing rolls with different materials (for example: plastic, paper materials or composite packaging materials, etc.), nor can they The problem of sealing volumes by embossing, transfer printing, etc. on the same or different materials, the product style is relatively single
