Production and preparation method of antibacterial preservative films

Abstract

The invention provides a production and preparation method of antibacterial preservative films. The production and preparation method comprises a tensioning mechanism, a pressure feed mechanism, a winding mechanism and a bottom plate, the pressure feed mechanism is mounted on the left end face of the bottom plate, the winding mechanism is mounted on the right end face of the bottom plate, and thetensioning mechanism is arranged between the pressure feed mechanism and the winding mechanism; and the tensioning mechanism is mounted on the bottom plate. The production and preparation method solves the problems that most of existing preservative film winding devices directly wind preservative films through winding drums, the tension force of the preservative films is inconvenient to control during winding, the preservative films cannot be kept flat, wrinkles are easily generated in the middle winding process, the preservative films are easily torn, the winding quality of the preservative films is influenced, negative influences are caused to the production efficiency, and dust attached to the surfaces of the preservative films cannot be effectively removed in the winding process of thepreservative films.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping film, in particular to a production and preparation method of antibacterial fresh-keeping film. Background technique [0002] Antibacterial food preservative film refers to a functional film that adds antibacterial agents to the preservative film to achieve the purpose of antibacterial and fresh-keeping through the slow release of antibacterial agents and photocatalysis; the preservative film is favored by people for its convenience, economy and beauty. favor; [0003] After the production and manufacture of antibacterial plastic wrap, it needs to be collected and stored by winding. Most of the existing plastic wrap winding devices directly wind the plastic wrap through the reel. It is not only inconvenient to control the tension of the plastic wrap during winding, but also Unable to keep the plastic wrap flat, it is prone to wrinkles during the middle winding process, and it is easy to tea...

Problems solved by technology

[0003] After the production and manufacture of antibacterial plastic wrap, it needs to be collected and stored by winding. Most of the existing plastic wrap winding devices directly wind the plastic wrap through the reel. It is not only inconvenient to control the tension of the plastic wrap during winding, but also Unable to keep the plastic wrap flat, it is prone to wrinkles during the middle winding process, and it is easy to tear the plastic wrap, which affects the winding quality of the plastic wrap and has a negative impact on production efficiency, and cannot effectively remove the fresh-keeping film during the winding process of the plastic wrap. The dust that film surface is contaminated; For this reason, the invention provides a kind of antibacterial fresh-keeping film production preparation method
