Description
Technical field
This utility model relates to the production field of synthetic leather, is specifically related to a kind of rubbing method and produces polyurethane PU synthetic leather half
The production line of finished product.
Background technology
The equipment for drying synthetic leather production line of prior art, is specific to the design of oleoresin coating.Oleoresin
In containing substantial amounts of toxic and harmful, environment and operator are brought injury greatly, and use oleoresin coating
The synthetic leather made also can remain poisonous and harmful substance, consumer is also resulted in harm.So people the most gradually start at present
Nontoxic water-base resin is used to carry out the production of synthetic leather.But owing to water-base resin containing substantial amounts of water, with existing
Oven equipment in technology is not enough to reach drying requirement.And drying when, if straight through air of coating surface
Blow and coating surface can be caused to be destroyed, and cause the outward appearance of product defective.If using infrared lamp to carry out illumination heating,
Although can effectively heat, and the coating surface of cloth there will not be air blow-through, but owing to the length of baking oven is longer, leads
Cause by the baking oven energy consumption of infrared lamp lampshade high；Additionally, due between heats and cloth and the infrared lamp of infrared light
Distance has direct relation, thus the heats of the cloth between adjacent two infrared lamps with just to the cloth of infrared lamp
Heats also differs, and i.e. infrared lamp is as the oven temperature of heating source uneven.
It addition, the water-base resin synthetic leather production line of prior art, need in acid solution, put the water-base resin on cloth
By washing, the acid on cloth is removed again after alternatively.This technics comparing is loaded down with trivial details, and can produce big in production process
