Description

A kind of film bag mouth opener

Technical field

The utility model relates to the packing technique field, relate to a kind of film bag mouth opener in particular, it can be applied in such as in the automatic packaging process of paper handkerchief, is used for strutting film automatically, is beneficial to down the step operation and can easily paper handkerchief be packed in the inner chamber of film formation.

Background technology

For products such as paper handkerchiefs, it generally all is into underwriting sells, and namely also includes packing film in the periphery of paper handkerchief.The packing of this paper handkerchief realizes by automated packaging equipment all that generally its packaging step generally is: utilize sucker to draw the good bag film of processing and fabricating in advance automatically from position, bag film locker room, this bag film is flats; Then utilize the film bag mouth opener that the opening of this bag film is opened, the recycling load transfer device is delivered to paper handkerchief in the bag film that has strutted, and bag film is sealed at last again and finishes the packing of one bag of paper handkerchief.

At present, when bag film being strutted action, existing film bag mouth opener generally all need process a sliding shoe, as shown in Figure 1, this sliding shoe 200 has first horizontal rail 210, second horizontal rail 220 and between first horizontal rail 210 and second horizontal rail 220 and play the oblique orbit 230 of transitional function, there is diff-H between this first horizontal rail 210 and second horizontal rail 220, so utilize this diff-H to realize opening and folding of two braces in the film bag mouth opener, this diff-H then can strut the distance of film for the film bag mouth opener.

Hence one can see that, and there is following defective at least in above-mentioned traditional film bag mouth opener:

One, owing to the distance between first horizontal rail 210 in this sliding shoe and second horizontal rail 220 is a fixed value, in order fully to support packing film, the sliding shoe of a kind of specification like this can only be used for supportting bag for a kind of packing film of specification, so often need to process the sliding shoe of plurality of specifications, not only cost is higher, and storage has increased work capacity to material;

Two, need change packing of product specification when board, when namely needing to adjust openings of sizes, then need to shut down and the replacing sliding shoe, so have ineffective defective;

Three, above-mentioned sliding shoe 200 need process first horizontal rail 210, second horizontal rail 220 and oblique orbit 230, and its difficulty of processing is bigger, and track is easy to wear, and the gap that this sliding shoe cooperates with slide mechanism is big, and can have influence on the accuracy of folding.

At the problems referred to above, the utility model people has developed this case through concentrating on studies.
