Description

Full-automatic double-face pre-coating film laminating machine
Technical field
The present invention relates to a kind of improvement invention of pre-coating film laminating machine.
Background technology
In the prior art, laminating machine mainly carries out one side film to overlay film printing, after an overlay film, to another side overlay film, so just realize two-sided overlay film conversely, the production technology of this backwardness is not only wasted production hour, power consumption, and during to an overlay film, another side is impaired because of friction, has affected product quality, and this traditional processing technology can not meet the production requirement of the two-sided overlay film of some high quality printing product; And the warm-up mill diameter all less (being generally 216mm) of current laminating machine, it is corresponding also less with the area that principal pressure roller printing product contacts, in order to ensure compound film quality, must ensure enough contact pressing times could press together film and paper completely, therefore, the velocity of rotation of overlay film pressure roll can not be too fast, otherwise just do not reach the required time of pressing.Cross slowly and affect overlay film speed, the too fast compound film quality that affects, this is the technical barrier that always perplexs overlay film industry.
Also there are problems in the laminating machine entirety on existing market: 1, paper is sling by chain one end on lifting platform, and the other end is free end, and in lifting process, the free end of chain is easily sticked in the gap on machine, and lifting platform cannot be worked; 2, paper feeding mode is to fly to reach head by employing paper is delivered on the conveyer belt of transport platform, paper overlaps in transport platform, before and after, paper overlaps, by conveyer belt, paper sheet delivery to location is located, by front lay and side mark, paper and paper are taken and mouthful positioned, adjust, then send into main frame overlay film.Adopt same motor by driving-chain transmission owing to flying to reach head, conveyer belt and front lay, thereby driving-chain is longer, transmission is very unstable, and the overlap joint of paper need to complete on the conveyer belt of transport platform, and transport platform that need to longer stroke, there is unstability in paper like this in conveying, and transport platform area occupied is large, make troubles to transport, installation and the arrangement of machine, in addition, paper moment in the time of front lay and side mark place pauses, and can cause paper to take mouthful larger error of appearance, finally causes printing to occur waste product, 3, the magnetic tension controller of controlling membrane tension can not be made corresponding tension variation according to the linear velocity of the operation of film, and on-line velocity can not be controlled membrane tension after occurring changing well, directly affects compound film quality, 4, current, the paper after good to overlay film is all that employing is air-cooled, because wind cooling effect is undesirable, causes film smooth not, easily deforms, 5, after the complete printing overlay film of overlay film, the conveying roller that will be run up is transported on finished product moving belt and transports, and the conveying roller and the moving belt that transport due to the laminating machine finished product of prior art are all by same driving motor transmission, by driving-belt such as chain links together moving belt and conveying roller, then realizing run-in synchronism by motor carries out product and carries and transport with finished product, but due in order to ensure that finished product after the overlay film of rear is subject to the impact of breadth, when energy fast shut-off, can not transport obstruction, therefore, the rotating speed of its conveying roller is very fast, and because moving belt and conveying roller are by same motor-driven, therefore its rotating speed is also very fast, when this will cause overlay film finished product on moving belt to transport because excessive velocities can be thrown out of body outside, cause waste.
Summary of the invention
In view of the deficiency of prior art existence, technical problem solved by the invention is in order to provide a kind of production efficiency high, the full-automatic double-face pre-coating film laminating machine that compound film quality is good, to achieve these goals, the present invention realizes in the following way: this kind of full-automatic double-face pre-coating film laminating machine, complete machine comprises paper advance mechanism successively, film-covering mechanism, cooling body, paper breaking mechanism, finished product conveyer and paper collecting mechanism, described film-covering mechanism includes warm-up mill and is positioned at the principal pressure roller of the pressing with it of its below, it is characterized in that: described principal pressure roller below is also provided with lower warm-up mill, described upper and lower warm-up mill correspondence is fitted with blowing film frame and lower blowing film frame, described principal pressure roller is connected with triangular oscillating α, principal pressure roller is arranged on the peak of triangular oscillating α, described triangular oscillating α has one laterally to protrude position, this laterally protrudes position and is hinged in frame, the horizontal protrusion position of described triangular oscillating α is to extending in the other direction, form the arm of force, the tail end of the described arm of force is connected with the piston rod of cylinder, described cylinder is arranged in frame, the diameter of described upper warm-up mill is 300mm-380 mm, the diameter of described principal pressure roller is 200mm-260mm, and bonded to each other, the volume film cylinder of described upper blowing film frame and lower blowing film frame is connected with magnetic tension controller, the tension force of described magnetic tension controller is adjustable by PLC.The present invention due to below have additional warm-up mill and lower blowing film frame under one group, realize the function of Double-side Synchronous overlay film, and by the enlarged diameter of principal pressure roller and warm-up mill, can make like this warm-up mill and principal pressure roller in the time of laminating, increase contact area, contact area increase can extend the pressing time of film in printing, and owing to adopting triangular oscillating α, pass through lever principle, as long as cylinder is upwards pushed up, just can be easily by the peak of triangular oscillating α taking the rotating shaft of protruding position as fulcrum, by the upwards warm-up mill application of force of principal pressure roller.Can increase like this portable cord speed of printing, but also can ensure the pressing time of film in printing, improve overlay film efficiency, reduce electric energy loss.
