Description

Technical Field

[0001] The invention relates to a large-scale bulk packaging machine and belongs to the field of packaging. Background Art

[0002] The bulk noodle bagging machine is mainly used for bagging bulk noodle, pasta and other bulk strip materials. It usually includes a bagging mechanism, a mouth-opening mechanism and a sealing mechanism. The bagging mechanism is mainly used to open the packaging bag and put it on the mouth-opening mechanism. The mouth-opening mechanism is mainly used to open the handbag after the packaging bag is put on, so as to facilitate the loading of materials into the handbag. The sealing mechanism is mainly used to seal the bag after the noodles are put into the packaging bag.

[0003] Dried noodles have long been a popular staple due to their delicious taste, convenience, low price, and easy storage. In regions with high demand for dried noodles, consumers prefer to purchase them in 5kg-10kg bags, which are both affordable and cost-effective. This also allows noodle manufacturers to save on packaging materials, thereby reducing production costs.

[0004] Currently, there are two main specifications for bulk noodle packaging: one is 5kg-10kg packaging, which uses a soft bag flat bag packaging mode. It is generally bagged manually and then sealed by mechanical equipment. It is labor-intensive and has low work efficiency; the other is 1.5kg-2.5kg packaging. This packaging can now be fully automatically mechanized produced, but universal fully automated equipment for 1.5kg-10kg has not yet appeared.

[0005] The utility model patent, granted with publication number CN209795987U, discloses a bag clamping device and a bagging machine for hand-held noodles. These devices address the existing problem of flaps being roughly equal in width to the unfolded bag width, making it difficult to fit the bag over the flaps. Furthermore, the flaps being roughly equal in width to the unfolded bag width, making it difficult to fit the flaps, resulting in a low bagging success rate. Currently, this device is only suitable for bagging 1.5kg-2.5kg bags and is not compatible with 5kg-10kg bags.

[0006] In response to the problems in the existing technology that 5kg-10kg cannot be fully automated and 1.5kg-10kg cannot be used compatibly, the present invention invents a large-scale bulk packaging bagging machine, which realizes multiple uses of one machine. Customers can flexibly choose the packaging form according to market demand. At the same time, it realizes the automated production of the equipment, reduces labor intensity, greatly improves production efficiency, and saves production costs. Summary of the Invention

[0072] Bag running direction:

[0073] The packaging bag is placed horizontally in the bag bin and is taken out from the bag taking station by the bag taking and feeding mechanism H3 and sent to the bag supporting station. The packaging bag is opened by the adjustable bag supporting mechanism H4, and the lifting mechanism H2 drives the bag supporting device H4 upward, and the packaging bag is inserted into the bottom of the material sorting and buffering mechanism H1; the material enters the packaging bag at the bottom from the material sorting and buffering mechanism H1, and the material in the packaging bag gradually increases.
