Tray type automatic packing production line for vegetable plastic wrap

Abstract

The invention provides a tray type automatic packing production line for a vegetable plastic wrap. The production line comprises a vegetable aligning device, a tray picking and conveying device and a fresh-keeping packing device; the harvested vegetables are respectively separated and transported through a vegetable harvesting belt; the vegetables fall the vegetable aligning belt; a cam and an aligning belt baffle are in tangent fitting to enable the whole aligning belt baffle to swing, and then the vegetable aligning belt conveys the aligned vegetables to a vegetable receiving box; a rotating jaw rotates to shift the vegetables into an opening below the vegetable receiving box and then the vegetables fall down; a cutting plate is matched with a cutting rod I and a cutting rod II; the cutting plate linearly moves to drive the cutting rod I and the cutting rod II to move opposite to a tray II in the middle part of the whole device along a linear slide rail III; then the vegetables and the tray II can be wrapped with the plastic wrap, and the plastic wrap can also be cut. According to the tray type automatic packing production line for the vegetable plastic wrap, the vegetable aligning device is arranged to achieve automatic position aligning of the vegetables, and therefore, the working efficiency is increased.

Description

Technical field [0001] The invention relates to a tray-type vegetable fresh-keeping film automatic packaging production line, which is suitable for automatically packaging vegetables with a tray of fresh-keeping film after vegetables such as lettuce and bitter chrysanthemum are harvested, and belongs to the field of agricultural automatic packaging equipment. Background technique [0002] As the world's largest vegetable producer, China accounts for 52% and 43% of the world's vegetable production and area respectively, and the proportion of vegetable exports has reached more than 10%, which shows that the vegetable industry should have considerable benefits. At the same time, with the development of science and technology and the improvement of living standards, people are not only paying more attention to the quality of vegetable commodities, but also increasing their packaging requirements, especially for tray-type cling film packaging that can be breathable and fresh. At prese...

Problems solved by technology

Although these packaging machines have solved the problem of improving packaging efficiency, they still cannot be separated from manual work for the sorting of vegetables before packaging, tray extraction, and vegetable loading.

Moreover, due to the complex action of the plastic wrap packaging process, the driving structure of the existing packaging machinery is also relatively complicated, which greatly increases the manufacturing cost, thereby increasing the price of the equipment, which is not conducive to the promotion of the equipment
