Description
Technical Field
The invention relates to the technical field of packaging boxes, in particular to a flat box sealing device for preventing a flat box from being opened privately in circulation links such as transportation, distribution, express delivery and the like.
Background
In order to improve the resource recycling rate and reduce the resource waste, the recyclable hollow plastic plate flat box is widely applied to factory turnover, logistics transportation turnover and express transportation turnover, the using amount of the disposable paper flat box can be greatly reduced, green package transformation can be promoted, excessive package can be avoided, the recycling rate can be improved through recycling for many times, and the packaging, transportation and production costs are reduced.
The flat mouthful of case of cavity plastic slab has simple structure relative to the packing box of other structures, retrieves convenient to use, low in production cost, empty case folding, storage and transport characteristics such as convenient, nevertheless has following weak point in packing, transportation and delivery process: when the flat box of the existing hollow plastic plate is sealed, only disposable adhesive tape can be used for packaging, so that the box is not convenient to disassemble and assemble, residual adhesive can be left on the box body, the box is not beneficial to cleaning and recycling, and the adhesive tape can be left for pollution; the adhesive tape is used for packaging, so that the adhesive tape is not easy to find in a circulation link after being opened, and the safety performance cannot be guaranteed.
In order to improve the safety performance of the circulation link and the pollution of the adhesive tape, the Chinese patent authorization publication No. CN211495211U discloses a rotary lock catch and a flat box, which are structurally characterized in that the box is sealed between a left box cover and a right box cover through the rotary lock catch, the flat box can be sealed by replacing a transparent adhesive tape, the flat box can be recycled for many times, and the pollution of the adhesive tape can be reduced. However, in the using process, the box sealing is troublesome, only manual box sealing can be performed, automatic box sealing can not be performed, the box sealing machine cannot be used on an automatic packaging production line, and the problems of inconvenient use, low box sealing efficiency, high labor intensity and the like exist. Therefore, the development of a flat box which has good safety performance, does not pollute the adhesive tape and can be used on an automatic packaging production line is a difficult problem which is urgently needed to be solved by the industry. Aiming at the problems, many manufacturers and acquaintances develop and develop the products, but no satisfactory products come out.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide the flat box sealing device which has the advantages of simple and reasonable structure, convenient recycling, safe and reliable use and good use effect and can be used on an automatic packaging production line.
The invention creates the technical scheme adopted for solving the above technical problems, which comprises a left box cover seat, a right box cover seat, a box body seat and a box cover sealing mechanism, wherein the left box cover seat and the right box cover seat are correspondingly fixed on a left box cover and a right box cover, the box body seat is fixed on a box body side plate, and the box cover sealing mechanism comprises a cover opening handle and a left sliding block and a right sliding block; when the cover opening handle is pulled downwards, the dovetail block of the cover opening handle is matched with the left dovetail groove and the right dovetail groove to push the left sliding block and the right sliding block to move outwards, and the left locking hook and the right locking hook are separated from the left locking hole and the right locking hole on the left box cover seat and the right box cover seat to be unlocked; when the left box cover seat and the right box cover seat are correspondingly pushed and pressed, the left lock hole and the right lock hole of the left box cover seat and the right box cover seat are matched with the lock hole inclined plane through the lock hook inclined plane to push the left slide block and the right slide block to slide outwards, and when the lock hole inclined plane correspondingly slides through the lock hook inclined plane, the left lock hook and the right lock hook are correspondingly inserted into the left lock hole and the right lock hole to automatically.
