Description

Technical Field

[0001] The invention belongs to the technical field of fruit bagging machine structures, and in particular relates to a fruit paper bagging opening machine. Background Art

[0002] As people's living standards improve, their requirements for fruits have shifted to high quality and pollution-free. The price of pollution-free fruits on the market is significantly higher than that of ordinary fruits, and the production of pollution-free fruits depends on whether the fruit bagging technology is applied. The biggest benefit of fruit bagging is to improve the appearance quality and reduce pesticide residues. The improvement of appearance quality is prominently reflected in the surface smoothness and comprehensive coloring. For example, the maximum degree of coloring of apples without bagging is 2 / 3, and the coloring area can reach more than 99% after bagging. The improvement of appearance quality and the reduction of pesticide residues are important conditions for my country's fruits to enter the international market. Fruit bagging is a necessary supporting measure for the development of the fruit industry.

[0003] At present, fruit farmers use manual labor to put paper bags on fruits. Among them, holding the paper bag is a time-consuming and laborious task. The specific process is: take out the paper bag from the cloth bag in front of the chest, twist the mouth of the paper bag, insert one hand into the paper bag and make a fist, slap the bottom of the bag with the other hand to deform the bag, then pull the hand back to hold the mouth of the bag, and then pull the hand out of the paper bag and hold the upper mouth of the bag; manual bag holding is time-consuming, laborious and inefficient. Therefore, there is an urgent need for a device that can automatically hold the bag.

[0004] The existing automatic opening machine technology mainly has the following problems: The size and weight of the mouth-opening machine are large, making it inconvenient to work in orchards and fields. The opening machine uses pneumatic suction cups to open the mouth. Multiple suction cups work at the same time. If one suction cup is detached, the opening may fail easily. In addition, the suction cups suck the fruit bag open from the outside. For double-layer detachable fruit bags, the inner bag is not easy to open. The mouth-opening machine has a complex structure, high cost and poor market acceptance. Summary of the invention
