Technical field
The utility model relates to a kind of compounding machine, more particularly, relates to a kind of compounding machine of producing the equal edition breadth holographic composite.
Background technology
The compounding machine of the holographic composite of existing production, generally comprise frame, unwinding device, sizer, set composite, drying unit and wrap-up, above-mentioned unwinding device, sizer, set composite, drying unit and wrap-up are installed on the frame successively, are provided with live-roller between the said apparatus; Above-mentioned unwinding device comprise unreel the seat and let off roll, let off roll is installed in and unreels on the seat; Above-mentioned set composite comprises composite roll and pressure roller; Above-mentioned wrap-up comprises rolling seat and wind-up roll, and wind-up roll is installed on the rolling seat; Above-mentioned let off roll and wind-up roll are referred to as winding up roller.
Holographic film on the unwinding device is behind sizer, be coated with one deck adhesive layer on its front, the holographic film that scribbles adhesive layer is positive compound set composite place and base material, thereby forms holographic composite, after the oven dry of holographic composite drying device, by wrap-up rolling rolling.
Owing to be subjected to the restriction of existing holographic film manufacture of materials technology, simultaneously, this also can produce error in manufacturing process holographic film, so, the space of a whole page and the length between the space of a whole page of the existing holographic film material of producing are inconsistent, and above-mentioned length is inconsistent to be irregular variation, even can produce sudden change, and error reaches more than the 0.5-2mm.The holographic film material of this precision, in the production process of holographic composite, after the processing of operations such as stretched, pyrocondensation, error can further be enlarged, make final packaging differ, accurately locate printing for back operation sheet-fed or the printing of roll web location brings very big difficulty with the version width of cloth length scale of material.
For these reasons, printing industry is making great efforts to solve the industry difficult problem always, for example, the patent No. is 200420032888.9, name is called the Chinese utility model patent of " radium-shine rainbow extrusion coating paper tension force control compensation arrangement ", a kind of technical scheme that solves the industry difficult problem is disclosed, this utility model adopts following technical scheme: the compound control tension compensating mechanism of a kind of radium-shine rainbow film paper power, be on the original basis of compounding machine, increased by a cover tension force control compensation arrangement, it is characterized in that: compensation arrangement is by encoder, probe, a pair of aligning roller, one cover jockey pulley and a linear encoder are formed, aligning roller is installed between plastic foil reel and the intake roller, intake roller and jockey pulley and preceding probe are installed between the rubber roll, encoder by gear driven is installed on the adhering roll, and back probe and linear encoder are installed on the travel line of compound back paper.This compensation arrangement is measured the repeat length of the radium-shine rainbow film in unreeling by encoder and probe (being photocell eye), adjust the tensile stress of radium-shine rainbow film again by complicated roller system, tensile deformation to radium-shine rainbow film carries out closed-loop control, change the length that radium-shine rainbow film extends, compensate, to reach the purpose of control version width of cloth precision.
But the disclosed technical scheme of above-mentioned utility model patent has following many drawbacks:
1, because the complicated roller of employing system regulates the tensile deformation of material, so system causes reaction speed slow because of complex structure, can't make adjusting, thereby the regulating effect of complicated roller system is undesirable to fast-changing error.
2, be in transmission connection by gear and adhering roll (being composite roll) owing to encoder, and the diameter of adhering roll is usually greater than 800mm, so, its accuracy of detection of encoder by gear driven that is installed on the adhering roll is low, is that the tensile deformation of material is regulated rapidly thereby further have influence on complicated roller.Import high resolution encoder (resolution ratio 5000 pulse/commentaries on classics with higher gears, 3000 rev/mins of maximum permissible revolutions) be example, because control accuracy requires to reach ± 0.1mm, then accuracy of detection causes less and must reach 0.02mm, therefore gear ratio should be 800mm * 3.1415926/0.02mm ÷ 5000=25.1, so, as long as the error>0.01mm between the travelling gear backlash, the error that produces when then end reaction is to encoder will be greater than 0.01mm * 25.1=0.251mm, considerably beyond the required required precision of system, and the error between the travelling gear backlash can not be less than 0.01mm, therefore, its accuracy of detection of encoder by gear driven that is installed on the adhering roll is low.
3, owing to probe (being photocell eye) is installed between the live-roller to detect the version seam of film or composite paper, so the accuracy of detection of probe is also lower.Reason is: because the tension force of film or extrusion coating paper changes, so, film or extrusion coating paper can produce shake during transmission between live-roller, the jitter amplitude minimum is also greater than 0.02mm, probe (being photocell eye) detects the film or the extrusion coating paper of shake, its accuracy of detection must be lower, considerably beyond the desired precision of system.
4, film and paper are through after compound, need enter baking oven dries by high temperature, film that is combined with each other and paper, in drying course, can produce deformation, therefore, if rolling tension force is not controlled, the error that the compensation composite paper produces because of deformation, still there is bigger abnormal error in the version seam of the extrusion coating paper of producing, the registration printing of influence back operation.
