Clamping and feeding system used for synchronous transmission of flexible membranes and application thereof

Abstract

The invention discloses a clamping and feeding system used for the synchronous transmission of flexible membranes, and the system comprises multiple clamping and feeding devices successively arranged at intervals along the feeding direction, wherein each clamping and feeding device comprises a movable clamping and feeding assembly and a stationary clamping and feeding assembly; the flexible membranes can be alternately clamped by each movable clamping and feeding assembly and the stationary clamping and feeding assembly; when the movable clamping and feeding assembly clamps, the movable clamping and feeding assembly moves along the feeding direction; and when the stationary clamping and feeding assembly clamps, the movable clamping and feeding assembly returns the circulating process of an initial clamping position to realize a purpose of feeding and transmitting the flexible membranes. The invention discloses a method which utilizes the system to synchronously transmit the flexible membranes. In the transmission process of the flexible film, the flexible film is always clamped by the clamping and feeding assembly. Meanwhile, the flexible membranes are returned and fed intermittently by the alternate switch of clamping or loosening. In addition, the feeding and driving assembly simultaneously moves to guarantee that the flexible membranes can be simultaneously fed on a plurality of positions.

Description

technical field [0001] The invention relates to the field of long-span flexible film transportation, in particular to a clamping and feeding system for synchronous transportation of flexible films and its application. Background technique [0002] As flexible membranes are widely used in papermaking, printing, textile, and flexible electronics manufacturing industries, researchers have invested more energy in studying flexible membrane delivery systems. Generally, the material of flexible film may be paper, plastic (such as PET) or metal (such as aluminum foil), and the shape may be rolled, sheeted or sheeted, and the device for conveying flexible film in the equipment system may use a roller It is possible to carry out roller conveying, and it is also possible to use a flat plate for clamping conveyance, but the continuous or intermittent conveying process is completed by applying pressure to the flexible film and utilizing the friction between the flexible film and the cla...

Problems solved by technology

For the method of reciprocating and synchronous clamping and feeding, Chinese patent document CN02144466.8 provides a feeding device and method using electrostatic clamping and clamping substrates, but electrostatic clamping is not flexible to any thickness and any material Membranes are effective, and sometimes static electricity can make separation of flexible membranes difficult, so electrostatic clamping is only suitable for some flexible membranes
