Description

Ironing equipment for hot melt film composite synthetic leather Technical Field The invention belongs to the technical field of synthetic leather processing, and relates to synthetic leather ironing equipment, in particular to hot melt film composite synthetic leather ironing equipment. Background The hot melt film is a film product, is commonly used for bonding various fabrics, paper and high polymer materials, has a similar structure to natural leather, is a plastic product which can be used as a substitute material of the synthetic leather, has quite similar front and back surfaces to leather and certain air permeability, and can be used for melting a glue layer to generate viscosity by heating the hot melt film, and can firmly combine the synthetic leather with screen cloth after cooling and solidification, so that the composite material is formed. Bonding by hot melt films typically requires the use of a platen tool, which is commonly used in the factory for proofing or bonding sheet-like materials. On the one hand, after pressing, the surface of synthetic leather still has certain temperature, need wait for its natural cooling to carry out the next process after, and the unable rapid emission of temperature cools off slowly, and on the other hand, current pressing tool is mostly flat, descends through hydraulic control roof, and the roof descends and presses with the bottom plate contact and scalds, and the staff leads to the finger to be pressed because of carelessly when carrying out the operation easily, and inefficiency moreover. Through searching, for example, chinese patent literature discloses a hot-pressing composite device of TPU hot-melt film and synthetic leather [ application number: 201320300497.X; publication number: CN203305624U ]. The hot melt film forming device comprises a TPU hot melt film roller, a non-grain ironing roller, a synthetic leather roller, a high-temperature composite roller, a cooling roller, a composite synthetic leather roller and a plurality of guide rollers, wherein the TPU hot melt film is arranged on the TPU hot melt film roller, the synthetic leather is arranged on the synthetic leather roller, gaps are arranged between the non-grain ironing roller and the high-temperature composite roller, the gap size between the non-grain ironing roller and the high-temperature composite roller can be adjusted so as to be suitable for composite synthetic leather with different thicknesses, the cooling roller and the composite synthetic leather roller are sequentially arranged after the non-grain ironing roller and the high-temperature composite roller, the TPU hot melt film is abutted with mesh cloth, high-temperature hot pressing is carried out between the non-grain ironing roller and the high-temperature composite roller, low-temperature cooling is carried out by the cooling roller, and finally winding is carried out on the composite synthetic leather roller, a plurality of guide rollers are also arranged on a route through which the TPU hot melt film and the synthetic leather can play roles of tensioning and guiding, the hot melt film and the synthetic leather ironing effect are horizontally placed, the hot melt film is only in a horizontal arrangement, the ironing effect and the hot melt film is low in forming efficiency and the pre-heating effect, and the hot melt device is low in ironing efficiency. Based on this, we provide a hot melt film composite synthetic leather's scalding equipment, but quick unreel rolling is got and is rolled up, has raw materials and preheats function and finished product cooling function, can carry out progressive scalding and pressing, scalds pressing effect good, efficient. Disclosure of Invention The invention aims at solving the problems in the prior art, and provides hot pressing equipment for hot melt film composite synthetic leather, which aims to solve the technical problems that: how to realize progressive ironing and pressing to form a flow line type ironing and pressing process of raw material unreeling, raw material preheating, progressive ironing and pressing, finished product cooling and finished product reeling. The aim of the invention can be achieved by the following technical scheme: the utility model provides a hot melt film composite leather's ironing press equipment, includes two pay-off preheating mechanism and ejection of compact cooling mechanism of placing side by side, pay-off preheating mechanism is linked together with ejection of compact cooling mechanism, and a plurality of rolling blowing mechanisms have been placed to pay-off preheating mechanism's front side, and the front side that the pay-off preheated mechanism is equipped with tensioning roller subassembly, and a rolling blowing mechanism has been placed to ejection of compact cooling mechanism's front portion, and the rear side that the pay-off preheated mechanism and ejection of compact cooling mechanism is equipped with the ironing press mechanism, and
