Device and method for packaging quick-frozen fruits and vegetables

Abstract

The invention discloses a device and method for packaging quick-frozen fruits and vegetables, and relates to the technical field of fresh food packaging. The device comprises a conveying belt, the conveying belt is provided with a plurality of charging buckets, and a suspension frame is arranged above the conveying belt; a bag placing mechanism, a feeding mechanism, a bouncing mechanism, a heat sealing mechanism and a discharging mechanism are sequentially arranged at the bottom of the suspension along a conveying line of the conveying belt, the bag placing mechanism comprises a first shell, a film barrel and a transmission wheel are symmetrically arranged in the first shell, a bag film is wound on the film barrel, and the end, away from the film barrel, of the bag film is fixedly connected with the transmission wheel. A first hydraulic cylinder is arranged over the bag film, the output end of the first hydraulic cylinder is fixedly connected with a push column, and a film outlet is fixedly formed in the bottom of the first shell. According to the fruit and vegetable bagging device, the shape of the bag film can be automatically controlled, the bag film is cylindrical, fruits and vegetables can be stably wrapped, the bagging stability is improved, manual operation is not needed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fresh food packaging, in particular to a device and a packaging method for quick-frozen fruits and vegetables. Background technique [0002] Fresh fruit and vegetable packaging refers to a technical means of external packaging of fresh fruits and vegetables. Through the means of fresh packaging, it can prevent the skin damage and abrasion of fruits and vegetables caused by uncontrollable factors such as collision and friction during transportation. Thereby bring the loss of property, so often will carry out transportation after packing the fruits and vegetables, in order to achieve the effect of reducing property loss. [0003] The invention patent of Chinese patent publication number is CN112173221A discloses a kind of fresh fruit and vegetable packaging method, and it uses a kind of automatic packaging equipment, and this equipment includes the automatic delivery device and the automatic packaging devic...

AI Technical Summary

Problems solved by technology

[0005] First: Put the fruits and vegetables on the protective film, and then push the main slider to move towards the auxiliary slider through the operation of the telescopic cylinder, and heat the plastic-sealed protective film with a scalding knife to seal and bag the fruits and vegetables. During this process, the protection The film is spread out in a rectangular shape. When the fruits and vegetables fall on the protective film, the sides of the fruits and vegetables cannot be blocked. Only two sliders are used to squeeze the two sides of the protective film closer together, and the fruits and vegetables are prone to fall. , the structural design is unreasonable and the practicability is low;

[0006] Second: Manual bagging can effectively control the shape of the protective film or bag film, making the bag film cylindrical, which is convenient for bagging fruits and vegetables, but manual bagging has low production efficiency and heavy workload, requiring a large number of operators. That is to say, a large amount of production costs will be invested, further reducing profit margins
