Abstract

The utility model discloses a packaging bag and a packaging machine. The packaging bag includes a first transverse seal edge and a second transverse seal edge both forming a transverse opening of the packaging bag, wherein the first transverse seal edge is point-sealed on the second transverse seal edge, and point seal blocks are formed on the first transverse seal edge and the second transverse seal edge; the point seal block on the first transverse seal edge is not overlapped with the transverse edge of the first transverse seal edge, close to the opening. The packaging machine includes an end seal mechanism, a side surface pressing device, a bag producer, a middle seal device and paper feeding belts on the two sides, wherein the middle seal device is used for slightly point-sealing the packaging bags. When the packaging machine is used for packaging objects to be packaged, the first transverse seal edge of the packaging bag is inwards folded on the second transverse seal edge through the bag producer, then the middle seal device is used for the point seal for the packaging bag filled with the objects to be packaged, therefore, when the packaged objects are taken out and used, the packaging bag is easier to open, in addition, the packaged objects in the packaging bag are prevented from being polluted by scraps of paper falling in the packaging bag when the packaging bag is opened.

Description

A kind of packaging bag and wrapping machine
Technical field
The utility model relates to medical curable product field, is specifically related to a kind of packaging bag and wrapping machine.
Background technology
Before, a large amount of packed articles all is stored in a large packaging bag, if once make, toos many or too much for use, and remaining packed article may be polluted in the process of depositing, thus the potential safety hazard of bringing.For fear of this situation occurring, at present, people are divided in packed article in independently packaging bag according to nonrecoverable deal, take out once and be finished and get final product from packaging bag during use, seal again two ends end envelope in the general elder generation of this independently packaging bag, like this, only need in use a hand therefrom to stretch at the envelope place, then packed article is taken out.In the packaging bag of prior art, form the first horizontal involution sideband inflection of packaging bag opening, the second horizontal involution sideband infolding, but in prior art, infolding refers to the involution place of middle envelope, outwards roll near an end at involution edge on the second horizontal involution limit, inflection refers to the involution place of middle envelope, outwards roll near an end at involution edge on the first horizontal involution limit, during underway envelope, by inflection and the fully middle envelope of infolding, so in use, open the package very inconvenient, and, when packed article is got at the middle envelope place that hand opens the package, the probability of packaging bag breakage is higher, the risk that paper scrap in packaging bag falls into packed article can increase.
In addition, the structure of wrapping machine of the prior art is as shown in Figure of description Fig. 1.The 1st, chart drum, the 2nd, paper roll, 3 and 4 is that (3 is drive wheel to a pair of conveying roller, 4 is rubber wheel), 5 is rocker arm roller, 6 is belt conveyor, 7 is packed article, 8 is bag making device, and 9 is the side pressure device, and 10 is the side sealing device, 11 is end sealing mechanism, 12 is finished conveying device, and 13 is glue spreader (envelope paper to some without gluing, 13 can remove).The transmission of envelope paper is by the conveying of roller 3 and 4, and after bag, packed article enters in packaging bag by belt conveyor, then by belt conveyor, packaging bag and packed article is transmitted forward.And then the lateral opening to packaging bag is pressurizeed by the side pressure device, the side sealing device carries out heat sealing to the side sealing, finally, tight involution is carried out at 11 pairs of packaging bag two ends of end sealing mechanism, so that packed article is divided in independently packaging bag according to nonrecoverable deal.In existing wrapping machine, when packaging bag is carried out to middle envelope, adopt in complete formula and seal, opening of packaging bag is very inconvenient.
Summary of the invention
