Description

Technical Field

[0001] The invention relates to a fruit and vegetable packaging bag covering device, belonging to the technical field of fruit and vegetable bag covering equipment. Background Art

[0002] With the improvement of people's living standards and quality of life, people's understanding of agricultural development and the value of agricultural food has undergone tremendous changes. Technical measures to ensure fruit quality have become the main problem that my country needs to solve now and in the future. In the field of agricultural apple production, in order to prevent the fruit from dust pollution, buffer collision, and make the fruit surface smooth and beautiful, the apples need to be bagged before packing. Specifically, the fruit nets are placed on the outside of the fruit one by one to prevent the fruit from being damaged by collision. The fruit nets are wound in a disc shape. At present, most apple production uses manual bagging technology for packing. Specifically, the fruit nets are cut one by one to the appropriate size and then bagged manually. The degree of automation is low, the bagging efficiency is low, the bagging quality is biased, the bagging situation is frequent, and the labor cost is high. Ordinary manual bagging can no longer keep up with the scale of agricultural production.

[0003] At present, there are some automatic bagging machines on the market, which specifically use a traction guide mechanism to pull the fruit net, then manually cut off the fruit net, and finally put the fruit net on the fruit through a bagging mechanism. The existing bagging mechanism has problems such as low bagging efficiency, high bagging cost, and poor bagging quality.
