A film covering device for packaging box production

Abstract

The invention discloses a film coating mechanism for production of packing boxes. The film coating mechanism for production of the packing boxes comprises a conveying mechanism and a film coating mechanism body, wherein the film coating mechanism body comprises a reel, a hydraulic driving assembly and a reeling roll; an original film which is reeled on the reel penetrates through a rubber-covered roll group and then is connected with a steering roll; the original film bypasses the steering roll and is connected with the reeling roll; a tension controller is arranged between the reeling roll and the steering roll; a main retractable rod, auxiliary retractable rods and an angular driving rod are mounted on the hydraulic driving assembly; the main retractable rod and the auxiliary retractable rods are connected with a pushing and pressing plate through spherical hinges; a cross-shaped reinforcing rib is arranged on the back side surface of the pushing and pressing plate; the main retractable rod is connected to the center of the pushing and pressing plate; the auxiliary retractable rods are uniformly connected to four corners of the cross-shaped reinforcing rib; the right end of the pushing and pressing plate is connected with an angle-regulating pressure plate through a flexible hinge; and the angle-regulating pressure plate is connected with the hydraulic driving assembly by the angular driving rod. By a coating and scraping integrated glue coating mode, gluing surfaces are glued uniformly; and by a unique film coating mode, film coating is implemented conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of product coating, in particular to a coating device for packaging box production. Background technique [0002] Laminating film, also known as "laminated plastic", "mounting glue", "sticking film", etc., refers to the use of transparent plastic film to be pasted on the surface of printed matter by hot pressing to protect and increase gloss. Laminating film has been widely used Surface binding and protection of book covers, picture albums, commemorative albums, postcards, product brochures, calendars and maps. At present, common laminated packaging products include packaging boxes, handbags, fertilizer bags, seed bags, self-adhesive labels, etc. In the prior art, large-scale production of packaging boxes is generally produced by large-scale laminating equipment, while in small-scale production or sample production, the film is generally heated by hand using an electric iron or electric wind to soften the fi...

[0002] Laminating film, also known as "laminated plastic", "mounting glue", "sticking film", etc., refers to the use of transparent plastic film to be pasted on the surface of printed matter by hot pressing to protect and increase gloss. Laminating film has been widely used Surface binding and protection of book covers, picture albums, commemorative albums, postcards, product brochures, calendars and maps. At present, common laminated packaging products include packaging boxes, handbags, fertilizer bags, seed bags, self-adhesive labels, etc. In the prior art, large-scale production of packaging boxes is generally produced by large-scale film-coating equipment, while in small-scale production or sample production, the film is generally heated by hand using an electric iron or electric wind to soften the film. Adhere to the surface of the packaging box, which is inefficient and uneven, which will easily lead to the scrapping of the film, which is more time-consuming and labor-intensive
