Description

Template type packaging bag folding binding machine

Technical Field

The utility model relates to a template formula wrapping bag folding strapper.

Background

The utility model relates to a packaging bag which comprises a plastic flat bag, a garbage bag, a medical bag, a food bag and the like, and also comprises a portable shopping bag with two handles. For storage, sale and transportation, the packaging bags produced by the bag making machine and the notching machine need to be folded once or twice, and for the portable shopping bag, the two handles need to be folded, namely, the two handles of the portable shopping bag are folded towards the middle respectively and are lapped together, then the two handles lapped together are wrapped in the portable shopping bag by folding once again, the folding mode is called as handle folding, and a mechanism for carrying out the folding on the two handles is called as a handle folding device. Application publication No. CN113371286A discloses a shopping bag folding machine, wherein a handle folding device of the shopping bag folding machine comprises a pushing and folding plate mechanism, a pressing plate mechanism, a template mechanism, a lifting platform mechanism and a plate inserting mechanism; application publication No. CN113060374A discloses vest bag folding equipment, which comprises a clamping and conveying folding lug mechanism (equivalent to a pushing and folding plate mechanism and a pressing plate mechanism), a bag body bearing mechanism, a bag body folding mechanism and the like, and further comprises a translation workbench and a positioning pressure head. After the two handles of the portable shopping bag are folded, the subsequent folding is called bag body folding, the bag body is partially folded once or is folded twice, and the folding mode of the bag body is consistent with the folding and bundling mode of a common flat pocket.

Regarding the aspect of bundling of packaging bags, application publication No. CN108910465A discloses a rubber band conveying device of an automatic bundling machine, which comprises a vibrating disk, a mechanical arm, a driving mechanism and a rubber band spreader. The manipulator grabs the rubber band in the vibration disc under the drive of the driving mechanism and then transmits the rubber band to the rubber band spreader. The patent publication No. CN209567107U discloses a packaging bag binding machine, which discloses a rubber band opening mechanism, including a transmission disc, a swing arm, and a material pushing plate, wherein the rubber band opening mechanism can open an annular rubber ring into a square shape corresponding to a packaging bag, and the material pushing plate (a bar releasing mechanism) can push down a rubber band on the rubber band opening mechanism from a material supporting shaft (equivalent to a supporting rod) to be sleeved on the packaging bag.

The problems existing in the prior art are mainly expressed in the folding aspect of the bag body: first, the folding is realized to the vest bag among the splint device through the picture peg in predetermined folding line position among the prior art, and the picture peg is at the position of folding line and inserts the book to the splint, owing to receive the different influence of both sides splint resistance at the in-process of inserting a book, the position of folding line deviates from the picture peg easily, leads to the shopping bag that the folding was come out not of uniform size, irregular. Secondly, related laws and regulations have been issued by related national departments to avoid white pollution, and the biodegradable raw materials are regulated to be used for producing the degradable shopping bags in future. The degradable shopping bag is characterized in that the bag body is very soft, and when the packaging bag is inserted into the clamping plate device by the inserting plate, the packaging bag is easy to collapse in the clamping plate device and wrinkles appear; third, the prior art is unfavorable for tying up in the aspect of the folding of the bag body, and the problem that it exists is: in the bundling process, one end of the packaging bag is clamped by a mechanical arm or a clamping plate, more than half of the length of the packaging bag is suspended outside, and then the suspended part is inserted into the stretched rubber band. Therefore, the part hung outside inevitably sags and bends, so that the projection surface of the end face of the packaging bag is enlarged, the rubber band needs to be sleeved with the bag after being unfolded greatly, the breakage rate of the rubber band is high, even the specification and the model of the rubber band have to be enlarged, and the bundling cost is increased. For the biodegradable packaging bag pushed by the country, the bag body is too soft, so that the part hung outside the manipulator or the clamping plate directly hangs down to a large extent, and even if the rubber band is stretched to a large extent, the bag is difficult to be sleeved.

On the basis of a handle folding device and a bundling device in the prior art, the bag body folding device is designed to be orderly folded, is not easy to bend in the bundling process, keeps a straight state, extends into a rubber band spreader to perform bundling, and is a problem which people want to solve but cannot solve.
