Packaging equipment for automatically shrinking through hot air

Abstract

The invention discloses packaging equipment for automatically shrinking through hot air. The packaging equipment for automatically shrinking through the hot air comprises at least one holding cavity,multiple flexible parts and at least one conveying channel, wherein a blanking port is formed in the top part of the holding cavity; the multiple flexible parts are arranged to form a surface structure; a first cavity and a second cavity are arranged in each flexible part; fluids with different temperatures are pumped into the first cavity and the second cavity through water pumps; the conveying channel communicates with the holding cavity; multiple hot air channels are arranged on the bottom end surface of the conveying channel in an array way, and can be used for conveying hot air into the conveying channel; a heater is arranged at the position, located above the blanking port, on the bottom part of the surface structure, and can be used for softening and packaging a packaging sheet on the outer layer of a fruit falling into the holding cavity at a time; and the fruit is conveyed and hot-sealed at the same time after entering the channel so as to be secondarily packaged, so that a packaging effect is better, and the packaging equipment for automatically shrinking through the hot air is flexible to use.

Description

technical field [0001] The invention relates to a packaging device, in particular to a packaging device that automatically shrinks through hot air. Background technique [0002] Packaging is the overall name of containers, materials and auxiliary materials used in a certain technical method to protect products during circulation, facilitate storage and transportation, and promote sales. It also refers to the process of using containers, materials and auxiliary materials to achieve the above-mentioned purposes. In addition to the operation activities of imposing certain technical methods in the field of circulation, the supplies that carry articles that have not entered the circulation field cannot be called packaging, but can only be called packages, boxes, containers, etc., because in addition to the function of packaging in parcel boxes, the packaging has no effect on articles. To modify and gain the favor of the audience is the important role of packaging. [0003] There...

Problems solved by technology

[0003] There are many cumbersome processes in the traditional fruit packaging process, and the flexibility of use is poor. Instead of sealing the cavity flexibly through flexible parts made of memory alloy, and preheating through the heat radiation of the heater, the fruit cannot be packaged. The outer packaging sheet softens and shrinks, or it is easy to cause damage to the packaging sheet. Some of them do not use hot air to soften the packaging sheet. Sex is not strong
