Description
Technical field：
The present invention relates to plastic sheeting manufacturing technology field, more particularly to a kind of plastic film closing device.
Background technology：
Polybag in process of production, it is necessary in the plastic film of expansion the rule impression of seal one one by one, thin
Film coiled material, because film coil is flexible material, easy fold or is heaved, on traditional sealing device during conveying
Lack the tensioning of corresponding film coil and apparatus for leveling, or tensioning and leveling effect it is bad, to film coil seal when
Wait, some row situations such as impression distortion can be produced by being sealed on film coil at position, the quality of product be influenceed, due to existing
Sealing device all carries out seal using heating plate up and down to film coil, because polybag is all plastic material, due to lacking phase
The dropping device and cooling device answered, because typically upper heater plate temperature is higher than lower temperature of heating plate in heating plate, are sealed
Print heating rear film coiled material is easily bonded in heating plate, influences normal production process.
The content of the invention：
The invention provides a kind of plastic film closing device, solve to lack during seal and film coil is opened
Tight and apparatus for leveling, and film coil easily bonds technical problem on hot plate during seal.
The technology solution of the present invention is as follows：A kind of plastic film closing device, includes two on workbench, workbench
Side is respectively inserted with guide rod of the axial line perpendicular to workbench, two guide rods is from bottom to top inserted with top board with successively
Formed on pressing plate, guide rod below the top of top board and lower platen and two axial lines are fixed with limited block, top board put down
Row is in the bearing pin of guide rod axial line, and the lower end sleeve of bearing pin is on lower platen, on the bearing pin part between top board and lower platen
It is inserted with the workbench immediately below the first spring, lower platen and is fixed with lower heating plate, the lower platen bottom relative with lower heating plate
Heating plate is fixed with face, the both sides of the length direction of lower platen are additionally provided with multiple leveling dropping devices, flatten dropping device
Include first connecting rod, second connecting rod, third connecting rod, one end of the first connecting rod is hinged on lower platen side, first connects
The other end of bar and the center of second connecting rod are hinged, and the one end of the two ends of second connecting rod respectively with third connecting rod is hinged, and the 3rd
The other end of connecting rod is hinged with briquetting, also includes second spring, and one end of second spring is fixed on first connecting rod, the second bullet
The other end of spring is fixed on top board, and lower platen is provided with cooling dropping device.
Preferably, cooling dropping device includes airduct, and airduct is fixed on the side of lower platen length direction side, and
It is provided with airduct periphery in multiple exhaust vents, exhaust vent alignment distance below heating plate.
The beneficial effects of the present invention are：The present invention is provided with leveling dropping device on lower platen, and plastic film exists
Conveyed between upper heating plate and lower heating plate, guide rod is moved downward under power source drive effect, in upper heating plate and lower heating
Before plate laminating seal, the briquetting in leveling dropping device is first fitted with plastic film, is constantly moved downward in guide rod
Cheng Zhong, lower platen is also being moved downward, and because first connecting rod is hinged on lower platen, briquetting is moved ahead forward, and plastic sheeting is entered
Row leveling tensioning, until lower platen is by the first spring top clamping, respectively to plastic sheeting under upper heating plate and the effect of lower heating plate
Coiled material is fitted and carries out seal, and the effect that such plastic sheeting is sealed is better, will not be produced impression and be distorted and influence product
The problem of quality, the cold wind that comes out of exhaust vent in the airduct in dropping device is now cooled down to the print that is sealed under upper heating plate
Cooled down at trace, prevent from bonding on hot plate, also due to the effect of wind-force downwards, plays a part of the plastic sheeting that comes off,
When guide rod is moved upwards, lower platen is also being moved upwards, because first connecting rod is hinged on lower platen, is come off dress in leveling
Put under self gravitation, briquetting is moved downward, the plastic sheeting that may be bonded in upper heating plate is come off, prevent from being bonded in
In heating plate, by the way that under these effects, plastic sheeting product seal effect is very good, and the yield rate of product has obtained effectively carrying
It is high.
