Household fresh-keeping film packaging machine

Abstract

The invention belongs to the field of plastic packaging, and particularly relates to a household fresh-keeping film packaging machine. The household fresh-keeping film packaging machine comprises a static shell, a first transmission groove, a roller shaft hole, a first ladder-shaped sliding groove, a blade mechanism, a first cover plate, a second cover plate and the like. The first transmission groove is formed in the upper end surface of the static shell, and the first transmission groove communicates with one side end surface of the static shell; a moving shell wobbles to 90 degrees around afirst pin shaft and a second pin shaft installed on the side end surface of the static shell; meanwhile, two rollers pump and send fresh-keeping films, and the fresh-keeping films fall according to own gravity and extend from one end of a film outlet hole; hands are moved away to enable the moving shell to wobble back to an initial position under the action of a scroll spring; and then the fresh-keeping films are pulled to package and the fresh-keeping films are cut. In the whole operation process, the fresh-keeping films are always in the packaging machine, after the operation, the fresh-keeping films are still in the packaging machine, the fresh-keeping films are prevented from being contaminated by dust, so that the hygienic requirements of food packaging are met; and the concealment of a blade by the packaging machine ensures the safety in the operation process.

Description

technical field [0001] The invention belongs to the field of plastic packaging, in particular to a household fresh-keeping film packaging machine. Background technique [0002] At present, traditional plastic wrap packaging machines generally include two types: cover-cut type and cut-cut type; since the front edge of the cover of the cover-cut type plastic wrap packaging machine is equipped with a blade, all cover-cut type plastic wrap packaging machines need to be cut during use. The extraction and cutting of the plastic wrap is realized by repeatedly opening and closing the lid; when extracting the plastic wrap, it is not only cumbersome to operate but also likely to hurt hands because the lid falls, which brings unnecessary danger to people; in addition, the scratch-cut type After the packaging is finished, a considerable part of the plastic wrap is exposed in the air. Long-term exposure will be contaminated with dust, and the plastic wrap will be polluted, thus failing t...

[0002] At present, traditional plastic wrap packaging machines generally include two types: cover-cut type and cut-cut type; since the front edge of the cover of the cover-cut type plastic wrap packaging machine is equipped with a blade, all cover-cut type plastic wrap packaging machines need to be cut during use. The extraction and cutting of the plastic wrap is realized by repeatedly opening and closing the lid; when extracting the plastic wrap, it is not only cumbersome to operate but also likely to hurt hands because the lid falls, which brings unnecessary danger to people; in addition, the scratch-cut type After the packaging is finished, a considerable part of the plastic wrap is exposed in the air. Long-term exposure will be contaminated with dust, and the plastic wrap will be polluted, thus failing to meet the hygienic requirements of packaged food.
