Problems solved by technology

For ultra-thin films, neither of these two prerequisites can exist stably, because the thickness of the ultra-thin film is limited and the tension it can withstand is low. It can't even drive the opening roller to rotate, so the spoke-type opening roller can't achieve stable and parallel expansion

Embodiment 1

[0039] The polyethylene film 105 has a width of 1700mm and a thickness of 0.006mm. The axial working length of the bending roller 102 and the flat roller 103 is 1900mm. The wrapping angle of the bending roller 102 is 130°-165°, the bending degree of the bending roller 102 is 20mm / m, the distance between the flat roller 103 and the top rubber roller 113 is 50-150mm, and the wrapping angle of the prepreg cloth on the flat roller 103 is 28° , the protruding direction of the bending roll 103 is the direction of the outer extension of the angle bisector of the angle bisector of the triangle formed by the film unwinding, bending roll, and flat roll with the bending roll 102 as the apex, as figure 1As shown, adjust the tension of the magnetic powder damper 106 to make the film rotate on the bending roller 103, the cylinder piston rod is connected to the flat roller 103, and the relative position of the flat roller and the prepreg cloth and the film pressure are controlled by the elong...

Embodiment 2

[0042] Using the film coating process below, the film coating device is the same as in Example 1, and the direction is opposite, such as image 3 As shown, glue is applied at the glue roller, and the gap (10 μm) between the scraper 112 and the glue roller 113 is controlled to control the amount of glue to be uniform, and then the ultra-thin film of the prepreg cloth is laminated.

Abstract

The invention discloses a simple parallel spreading and laminating device for a wide ultrathin membrane. The simple parallel spreading and laminating device comprises a membrane unreeling roller, a magnetic powder damper, a bent roller, a gluing roller, a flat roller and a rack. A technology comprises the steps that the wrapping angle of the bent roller and the wrapping angle of the flat roller are adjusted by setting proper unreeling tension; the relative position relation of the unreeling roller, the bent roller and the flat roller is adjusted; the protruding direction of the bent roller is adjusted; and the membrane passes through the unreeling roller, the bent roller and the flat roller and then is combined with pre-soaked cloth to complete the laminating procedure. According to the simple parallel spreading and laminating device and technology for the wide ultrathin membrane, non-uniform elastic deformation is generated in the middle area and the edge areas of the membrane through the axial stroke linear change of the bent roller and the elasticity of the membrane, the spread membrane is fixed in the weft direction through the flat roller so that the ultrathin membrane can be spread, and the problems that the ultrathin membrane has wrinkles and is unevenly spread in the unreeling process can be effectively solved; unreeling is stable, the spreading parallelism of the ultrathin membrane is good, the breadth is stable, bonding to glued fibers is good, the phenomenon that bubbles are brought due to wrinkles of the membrane is thoroughly eliminated, and the finished product rate of the pre-soaked cloth is increased.

Description

technical field [0001] The present invention relates to a film unwinding and unwinding device and process, which is used for film unwinding and film coating of mono-oriented prepreg fabrics, and in particular to the simple wide-width ultra-thin film of several micrometers to more than ten micrometers of polyethylene film The lamination device and process are developed in parallel. Background technique [0002] The production of prepreg requires that the filament fibers be spread in parallel, and the fibers with a diameter of micron are required to be evenly spread, glued, and coated. Molecular weight polyethylene fiber non-woven fabrics, carbon fiber prepreg tapes and aramid non-woven fabrics need to be covered with a thin elastic film during production. Because the required film is very thin, it is generally only a few microns to a dozen microns , the tensile strength and modulus are very low, and the tensile force that can be borne is very low. The use of traditional rubb...
