Release paper stripping device on paper winding device 4 peels off release liners, and is batched by the wind-up roll up and down of release liners winding device 4
Release liners, leave the laminated cloth of shaping；Then the laminated cloth being molded first passes through the transition roller of barrier film unwinding equipment 5, Ran Houjing
Cross the press bonding roller of top, press bonding roller is wound with barrier film, when being molded between laminated cloth two press bonding rollers of entrance, motor
And press fit device, make barrier film be attached to shaping laminated cloth and press；Then described laminated cloth passes through shearing device 6 to enter winding
Device 7, wrap-up 7 batches to the laminated cloth with barrier film, is adjusted by the handwheel of adjustment left and right and upper-lower position
The position up and down of whole laminated cloth wind-up roll, so as to obtain neat batch effect, after being wound to the length of needs, drive
The upper and lower air motor of shearing device 6 support and cylinder, make close up and down while rotating shaft rotation between support, drive in rotating shaft
The friction-saw piece operating of setting is simultaneously close to each other, carries out severing to laminated cloth.
The technological process of production：
Fiber piddler → release liners unreel → and release liners and fiber pressing → release liners peel off the laying of recoverys → barrier film and pressing
The winding of → laminated cloth and cutting
Fiber piddler：Fiber drawn by the bobbin that five rows are distributed up and down, then obtains equally distributed fibre through sub-wire warping step
Dimensional plane, is scattered in 1600mm width with 360 one threads, and surface density is the fiber plane of 300g/.
Release liners unreel：Unreeled using release liners friction-type, so that upper and lower two-layer release liners is unreeled with 10m/min linear velocity,
By above-mentioned fiber plane holder between upper and lower two-layer release liners, and release liners glued membrane is inward-facing and outside in fiber plane.
Release liners and fiber pressing：Three layers of carrier that fiber plane and two-layer release liners are constituted are put into temperature and are maintained at
Between 200 DEG C of pressing hot-rolling, and the pressure of in addition 15kg/cm, keep pressing hot-rolling constant temperature and pressure 15 minutes, make fiber attached
In release liners film surface, and be not pressed in glued membrane；It is then shut off oil temperature heating system, open cooling system, and keep former
Pressing chilling roller is cooled to room temperature rapidly and three layers of carrier cooling is processed by some pressure.
Release liners are peeled off and are reclaimed：The release liners of two-layer up and down that the upper and lower surface of above-mentioned three layers of carrier is had are peeled off, release
The recovery of paper adopts friction-type to wind, and so that upper and lower two-layer release liners is smoothly wound around, and rolling speed is 10m/min.
Barrier film laying and pressing：Barrier film, adjustment pressing pressure are added to the surface of the shaping laminated cloth after once peeling off
Power is 15kg/cm, the laminated cloth of shaping is pressed, obtains one kind and prevent adhesion, antipollution laminated cloth.
Laminated cloth winding and cutting：Ensure that laminated cloth is continuously closely neat to batch, wrap-up adopts the gas of identical tension
The axle that rises winds, and adjustable about one end, one end is adjustable up and down, tension adjustment to 150 N m；When reaching the length needed for user,
Drive special friction-saw piece to be cut using air motor, make saw blade rotating speed reach 10000r/min, cut into rapidly
Product laminated cloth, can avoid the defects such as hair stubble.
