Fresh food cold-chain logistics automatic sealing and packaging system

Abstract

The invention relates to the technical field of fresh food packaging processing, in particular to a fresh food cold-chain logistics automatic sealing and packaging system which comprises a first conveying mechanism, a second conveying mechanism, an extrusion device and an extraction device. The second conveying mechanism comprises a second driving motor, a second supporting frame, second supporting legs, second transmission rollers, a second conveying belt, a second main transmission belt, a second auxiliary transmission belt and a packaging box. The extrusion device comprises a rotating motor, a driving gear, a first sliding block, a second sliding block, a first rack, a second rack, a sliding rod, a first supporting rod, a second supporting rod, an extrusion plate, a telescopic rod, a sponge plate and a heat sealing cutter. The extraction device comprises a [-shaped frame, an electric lifting cylinder and a vacuum extractor. In the vacuumizing and sealing packaging process of fresh food, the requirement for large-batch production is met, and the fresh food cold-chain logistics automatic sealing and packaging system has the effects of being high in packaging speed, good in packaging quality and high in packaging continuity.

Description

technical field [0001] The invention relates to the technical field of fresh food packaging and processing, in particular to an automatic sealing packaging system for fresh food cold chain logistics. Background technique [0002] Fresh products include fruits, vegetables and meat. With the improvement of people's living standards, people's demand for fresh products has increased sharply. Water loss and spoilage are fast, so the packaging, transportation, storage and sales of fresh products are a great challenge. In order to cooperate with the sale of products to consumers, many products are packaged in waterproof plastic bags or wrapped with plastic wrap and other films to wrap the products and trays together. [0003] Yet in the process of carrying out hermetic packaging for meat, generally adopt vacuum-pumped hermetic packaging. Vacuum packaging can inhibit the growth of many spoilage microorganisms by maintaining an anoxic environment in the packaging bag, slow down the...

AI Technical Summary

Problems solved by technology

In the existing vacuum packaging process for meat, the vacuum packaging bag is manually filled with items to be vacuum packaged, and then the vacuum packaging bag is placed on the side of the vacuum packaging machine, and the vacuum packaging bag is vacuumed by a vacuum pumping instrument. In this process, the two steps of plastic sealing and vacuum pumping are often used separately, so that the equipment cannot be vacuumed efficiently in the actual use process. The actual working efficiency of the equipment is reduced, and on the other hand, it cannot meet the needs of mass production
