The operation principle of the present invention:The present invention completes the overlay film behaviour of packing box by setting conveying mechanism and film-covering mechanism
Make, when device works, packing box is delivered to loading disk by feeding roller group, and loads the fixed hurdle on disk in original state
For contraction state so that packing box can smoothly enter the top for loading disk, and after packing box enters, fixed hurdle rises will packaging
Box, which is positioned at, to be loaded in disk, and now hydraulic-driven group is by driving main expansion link, auxiliary expansion link and angle drive rod, so that pushing away
Pressing plate and whole angle presser motion, former film is fitted on packing box, and keeps the action pushed, loads the motor driving of tray bottom
Load disk to rotate, so that packaging film be peeled off from former film, due to heating plate built in push plate, so as to keep well
Its viscous glutinous type, after the film of packing box surface, hot melt knife, which promotes, cuts off overlay film, and while corner, angle drive rod continues
Promote, so that whole angle pressing plate and push plate have a certain degree, turn to so as to adapting to packing box and turn in rotation process
Overlay film during angle turns to, more conducively the surface coating of packing box, and the packing box after the completion of overlay film is by lead screw gear straight
Lower operation is transferred in line rail;
When former film on the reel is by rubber roll group, interarea is glued, and the former film after gluing is by spreading knife by former film
The sizing material leveling on surface and uniformly, and unnecessary sizing material is peeled off by the turning slot of spreading knife, former film is turned by slewing rollers
To the conveyor surface of packing box, and the tension force of former film is carried out by tension controller, so as to be advantageous to being smoothed out for overlay film,
Prevent the phenomenon of gauffer.
In summary, the main characteristic of the invention lies in that:The rotation for the loading disk that the present invention passes through conveying mechanism, so as to
The operation of overlay film is carried out to packing box after packing box shaping, avoids breaking overlay film during cardboard tangent line in packing box
It is bad, while the conveying mechanism of the steering set, it can be transported using the loading disk and loading disk of motor-driven rotation in straight line rail
Dynamic screw drive mechanism, realize fast and the operation of efficient overlay film, pass through the push plate and whole for setting hydraulic-driven group to drive
Angle pressing plate, and the push plate connected by ball pivot and whole angle pressing plate can realize the regulation and control of multi-angle, pass through flexible hinge
Whole angle pressing plate can have good restoring force, avoid overvoltage from causing packing box deformation, can perfectly be bonded packing box in corner
When state, pass through the tension force that tension controller and slewing rollers control former film so that the process of fitting is more smooth, reduces fitting
Bad product rate.
