Description

Four banding mechanisms

[ technical field ] A

The utility model relates to a equipment for packing technical field especially relates to a four banding mechanisms.

[ background of the invention ]

The horizontal full-automatic packaging machine adopts a filling mode of firstly making bags and then discharging, and a discharging opening can directly go deep into the bottom of the packaging bag for discharging, so that dust can be prevented from flying. If the powder particles are extremely fine and easy to be raised, a dust catcher suck-back device can be added at the upper sealing to suck a little powder absorbed by the bag opening. In addition, horizontal full automatic packaging machine has adopted horizontal seal to consolidate leakproofness. The design can completely solve the phenomenon of 'bounce', and the sealing performance of the seal is ensured to the maximum extent, so that the quality guarantee period of the product is effectively prolonged. Secondly, when producing mixed materials (such as instant soup, spare rib soup, chicken essence, monosodium glutamate, health care products, spices and other powder products), manufacturers often encounter the problem that generally, each brand of soup has a unique formula, and the right proportion of the formula determines the purity of the taste.

The vertical packaging equipment cannot increase stations on the equipment, so materials must be mixed in advance during filling to carry out blanking, but in actual production, the mixing ratio of an actual product is not consistent with the formula ratio due to the fact that the materials are mixed in advance or the materials are not uniform in the transmission process. The horizontal packaging equipment can meet the requirement of increasing stations of manufacturers due to the characteristic of transverse bag moving. In addition, the horizontal packaging equipment can be infinitely increased in stations theoretically. In the bag-moving process, different materials can be loaded into each bag one by one through different blanking devices. For example, one bag of instant soup stock contains powdery materials (such as salt and chicken essence) and granular materials (such as dehydrated vegetables and dehydrated beef), the first blanking device is used for feeding the powdery materials in the bag moving process of the horizontal packaging equipment, the second blanking device is used for feeding the granular materials after the bag is moved horizontally once, and the rest can be done in the same way. Referring to the horizontal full-automatic duplex bag packaging machine, we can also find that the material compatibility of the horizontal full-automatic packaging equipment is very strong.

However, the existing horizontal full-automatic packaging machine is not suitable for popularization and use because plastic films are hot-pressed into packaging bags in a horizontal transportation mode, the packaging bags are sequentially transported to quantitative blanking work stations to pot materials in proportion, the packaging bags filled with the materials are sealed and then cut into individual packaging bags, the individual packaging bags are collected after being made into bags in a horizontal stepping transportation mode, the individual packaging bags are canned after being canned, and the individual packaging bags are finally cut after being canned after being sealed after being canned.
