Abstract

The invention discloses a continuous production method and the equipment of a plastic clamp net membrane with high strength and long service life. The plastic clamp net membrane has a fiber net clamped between an upper plastic membrane and a lower plastic membrane. The production method is that the fiber wire is plaited into the fiber net by a net forming device; the fiber net is directly drawn by a composite roller in a plastic composite device and is composite with an upper plastic membrane and a lower plastic membrane and clamped between the upper and the lower plastic membrane; after that, the cooling, edge cutting, cutting off and coiling are carried out. The used production equipment is a net forming device and a plastic composite device. The net forming device is provided with a frame which is provided with a rotary yarn frame; the rotary yarn frame is fixed with a plurality of yarn fixing shafts orderly arranged; the frame is fixed with a drive chain wheel, a driven chain wheel and chains engaged with the drive chain wheel and the driven chain wheel; the chains are arranged on a chain guideway fixed on the frame; the chain is fixed with a plurality of yarn guide plates uniformly arranged; the yarn guide plates are provided with yarn guide holes.

Description

Technical field: [0001] The invention relates to a plastic film product, in particular to a plastic sandwich film with high strength and long service life, a continuous production method and equipment for the plastic sandwich film. Background technique: [0002] At present, plastic film has occupied an important position in daily life due to its light transmission, heat preservation, low cost, harmless environmental protection, and convenient use. However, because the thickness of the existing single-layer film is generally only 0.02-1 mm, the strength is low and the application range is small. In order to solve the problem of low strength of single-layer film, people invented multi-layer composite film, that is to use plastic compound device to compound multi-layer plastic film together. There are many compound methods such as dry compound, hot melt compound and hot melt compound. . Although its strength is improved compared with that of a single-layer film, it still cann...
