Description

Technical Field

[0001] The utility model relates to the technical field of bag opening machines, in particular to a feeding mechanism. Background Art

[0002] In the food, pharmaceutical, health care, chemical, metallurgy and other industries, powders are usually packed in two bags, an outer bag and an inner bag. For the inner bag, when conveying the bag between the belt conveyor and the bag unpacking machine platform, in order to smoothly convey the bag to the bag unpacking machine platform, a transition roller is generally set in the middle, or a running belt is also set on the bag unpacking machine, or the bag is pushed over by a push rod mechanism, or a height difference is set between the belt conveyor and the bag unpacking machine platform. However, if a transition roller is added or a running belt is also set on the bag unpacking machine, it is difficult for the bag unpacking machine to seal at the transition roller or running belt, and dust will float out when the bag unpacking machine is unpacking the bag. Secondly, the cleaning workload of the bag unpacking machine will increase. For the two methods of pushing the bag over by a push rod mechanism or setting a height difference between the belt conveyor and the bag unpacking machine platform, since the inner bag is filled with powder, the bag will be easily deformed, the feeding position is inaccurate, and it is not conducive to the bag unpacking machine to take the material.
