Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a material unloading mechanism. Background Art

[0002] Many existing products, such as soft-boiled eggs, are soft in texture and are easily damaged when packaged into bags. Application No.: CN201821363654.0 proposes a soft-boiled egg bagging device, including a feeding part and a bag feeding part, wherein the feeding part is an inclined cylindrical feeding cylinder, and the bag feeding part includes a containing cylinder, a bag-carrying cylinder and a bag-supporting mechanism, wherein both upper and lower ends of the containing cylinder are openings, and the bag-carrying cylinder is closely arranged above the containing cylinder, and the bag-supporting mechanism includes a bag-supporting cylinder arranged on the side of the containing cylinder and a bag-supporting lever arranged at the bottom of the containing cylinder, and the bag-supporting lever is provided with at least two and both are connected to the supporting cylinder by a connecting rod. On the power end of the bag cylinder, the advantage of the utility model is that after the soft-boiled egg enters the receiving cylinder through the feeding cylinder, the bag-opening cylinder drives the bag-opening lever to open the corresponding packaging bag, so that the soft-boiled egg falls into the packaging bag under the natural action of gravity, and at the same time cooperates with the auxiliary boosting effect of the bag-opening cylinder to ensure that each soft-boiled egg can fall into the packaging bag smoothly. However, in the above structure: the angle of the device is fixed, and there is a large height difference between the outlet of the receiving cylinder and the bottom of the packaging cavity of the packaging bag. When the soft-boiled egg freely falls from the receiving cylinder to the bottom of the packaging cavity of the packaging bag, the height potential energy is converted into kinetic energy, which will still cause impact on the soft-boiled egg, resulting in damage to the soft-boiled egg.
