Plain end box sealing device

Abstract

The invention discloses a plain end box sealing device. The plain end box sealing device comprises a left box cover seat, a right box cover seat, a fixed box body seat and a box cover sealing mechanism, wherein the box cover sealing mechanism comprises a cover opening handle, a left sliding block and a right sliding block; the cover opening handle is arranged on the box body seat in an elastic reset mode; a dovetail block is arranged on the cover opening handle; the left and right sliding blocks capable of elastically resetting are symmetrically arranged on the two sides of the dovetail block; dovetail grooves in the left and right sliding blocks are in sliding fit with the dovetail block; left and right lock hooks are arranged on the left and right sliding blocks; left and right lock holes are formed in the left and right box cover seats; lock hook inclined planes and lock hole inclined planes which are matched with each other are correspondingly arranged on the left and right lock hooks and the left and right lock holes; when the cover opening handle is pulled, the left and right lock hooks are separated from the left and right lock holes for unlocking; and when a sealing box pushes the left and right box cover seats, the left and right lock hooks are automatically inserted into the corresponding left and right lock holes. After the structure is adopted, the plain end box sealing device has the advantages of simple and reasonable structure, convenience in recycling, safety and reliability in use, good use effect, capability of being used on an automatic packaging assembly line and the like.

Description

technical field [0001] The invention relates to the technical field of packaging boxes, in particular to a flat box sealing device that prevents the flat box from being opened privately in circulation links such as transportation, distribution, and express delivery. Background technique [0002] In order to improve the recycling rate of resources and reduce the waste of resources, recyclable hollow plastic board flat mouth boxes are widely used in factory turnover, logistics transportation turnover and express transportation turnover, which can greatly reduce the use of disposable paper flat mouth boxes, not only It can promote the green transformation of packaging, eliminate excessive packaging, and improve the utilization rate of recycled packaging through multiple recycling, reducing packaging, transportation and production costs. [0003] Compared with packing boxes of other structures, hollow plastic plate flat mouth boxes have the characteristics of simple structure, c...

Problems solved by technology

[0003] Compared with packing boxes of other structures, the hollow plastic plate flat mouth box has the characteristics of simple structure, convenient recycling and use, low production cost, empty box folding, convenient storage and handling, etc., but there are the following shortcomings in the process of packaging, transportation and distribution: At present The hollow plastic board flat mouth box used can only be sealed with disposable tape, which is not only inconvenient to disassemble, but also leaves residual glue on the box body, which is not conducive to cleaning and recycling, and there will be tape pollution; use tape Encapsulation, it is not easy to be found after opening in the circulation link, and the safety performance cannot be guaranteed

In response to the above problems, many manufacturers and people of insight have developed and developed, but so far no satisfactory products have come out.
