Description

Fixed-length feeding device

Technical Field

The utility model relates to a technical field of laminated glass film production.

And more particularly to a fixed-length feeding device.

Background

The TPU film mainly comprises polyurethane elastomer and is a film prepared by a special process. The method is widely applied to the fields of armors, airplanes, automobiles, information technology, new energy, high-end equipment and the like. The TPU film can be effectively combined with a PC plate, namely organic glass, and can be used as bulletproof glass and smash-proof glass.

The TPU film has the characteristics that: the TPU high-grade bulletproof film has extremely high strength which is 5 to 10 times that of a PVB film. The bulletproof glass can be effectively applied to bulletproof glass of banks and anti-smashing glass of villas. The penetration test of common PVB film for bulletproof glass hardly meets the standard, and the TPU film can prevent the bullet from penetrating and prevent the back of the impacted glass from flaking off. The TPU film has the characteristics of extremely high toughness and high brittleness different from the PVB film. The TPU film is made of only one material, is neutral, cannot react with other materials such as a PC (polycarbonate) endurance plate and a curtain wall glue, is nontoxic and tasteless, and is a high-tech environment-friendly material. The TPU film can reduce ultraviolet rays to the maximum extent and shield over 99 percent of harmful light. This is advantageous for avoiding damage due to ultraviolet radiation.

When the laminated glass is manufactured, the size cutting is mostly carried out by manually comparing the sizes of the glass or using a measuring tool. The method has the inherent structural defects, the initial fixed position of the film on the winding roller is difficult to keep consistent, and the uncertainty of the length of the film between the cutter and the roller after winding is finished can influence the accuracy of the final total length of the film, the calculation is complex and tedious, and the production progress is seriously influenced; in addition, in the prior art, the mode of cutting by manually using a measuring tool is low in production efficiency and high in labor intensity.
