Abstract

The invention relates to a PEVA membrane hot pressing compounding machine which comprises a rack, two unreeling mechanisms, a plurality of transition rolls I, a plurality of transition rolls II, a plurality of transition rolls III, a plurality of transition rolls IV, regulation rolls I, regulation rolls II, heating devices, pressing devices I and reeling machines; an aluminum plated PET membrane substrate or a nylon membrane substrate and a PE membrane substrate are heated by the heating device, then pressurized and compounded by the pressing device I and reeled by the reeling machine finally, the compounded substrate subjected to reeling is put into the unreeling mechanisms again to enable the compounded substrate is compounded to the PE membrane substrate to form a three-layer membrane compound structure, the upper and lower layers are PE membranes, and the middle layer is an aluminum plated PET membrane or a nylon membrane, so that a PEVA membrane material required by a bag making machine is reached, the compounding efficiency is high, glue does not need to be used, the cost is lowered, and the requirement for green and environment-friendly production is met.

Description

technical field [0001] The invention relates to the field of composite machines, in particular to a PEVA film hot-press composite machine. Background technique [0002] With the widespread promotion of PEVA film and the increasing prosperity of the packaging industry, many packaging bags require three or more layers (PE and nylon composite, EVA surface in contact with nylon; PE and PET aluminized film composite, EVA surface in contact with PET aluminized layer) , due to the extremely strict safety and health requirements for food and liquid packaging, green and environmentally friendly PEVA films are increasingly favored by manufacturers, mainly PEVA films, and high-end composite products. PEVA is polyethylene-vinyl acetate, which is a blend of PE and EVA. It has good softness and a little elasticity. The higher the proportion of PE, the more difficult it is to handle. It is generally used for production membrane. The ratio of these two chemicals can be adjusted to meet di...
