Description
Technical field
This utility model relates to the production field of synthetic leather, is specifically related to a kind of polyurethane PU synthetic leather semi-finished product and produces
Line.
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.It is that cloth is carried out blow-through with oven equipment of the prior art
, because oleoresin viscosity is relatively big, even if so airduct is directly facing to oiliness tree in the case of oleoresin coating is not solidified
Fat coating is blown, and is also not result in that the air that oleoresin coating surface is flowed destroys, so existing baking oven is in order to dry effect
Really, it is all facing to cloth blow-through by airduct, but water-base resin viscosity is less, water-base resin coating quilt in the case of not solidified
If airduct blow-through, the surface of water-base resin coating can be caused to be destroyed, and then cause the outward appearance of product defective；And due to
Containing substantial amounts of water in water-base resin, water-base resin also can evaporate a large amount of steam, cause oven equipment of the prior art
It is not enough to reach the drying requirement of water-base resin polyurethane PU synthetic leather.If using infrared lamp to carry out illumination heating, though
So 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, cause
The baking oven energy consumption using infrared lamp lampshade is high；Additionally, due between heats and cloth and the infrared lamp of infrared light away from
From there being direct relation, so the heats of the cloth between adjacent two infrared lamps and just adding the cloth of infrared lamp
Thermal effect 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
The acid waste water of amount, the process for waste water is cumbersome, and processing cost is higher.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, it is provided that the air-out of the discharge pipe in a kind of baking oven
The wind direction of mouth the most directly blows to cloth, and the wind direction of the air outlet of the discharge pipe in baking oven the most directly blows to cloth, it is ensured that aqueous is coated with
While moisture content rapid evaporation in Ceng, it is to avoid the aqueous coating of design on fabric surface breaks not solidified time under wind-force effect
Bad surface quality；And compared to infrared lamps, its energy consumption is relatively low；Air outlet is directly arranged in the sidewall of discharge pipe, it is simple to
Discharge pipe be directly produced processing, reduce production cost；By air outlet being located at the bottom of discharge pipe, and under air outlet
Side is provided with baffle plate, it is simple to existing oven equipment is transformed；By the effect of the exhaust column at baking oven top, baking oven is included in a large number
The air of steam is extracted out, it is ensured that the continuation of cloth is dried；In baking oven, use hot blast is as heat-conducting medium, by the stream of hot blast
Dynamic, it is ensured that the homogeneous heating degree in baking oven；Dry, by cloth by the cloth after impregnation is directly entered baking oven
Moisture is directly removed, thus reduces technological process, it also avoid the generation of acid waste water, reduces the processing cost of waste water；
Different according to the medium in dipping device, and by the use of ironing device, the second apparatus for coating and the second baking oven whether, make
Obtain production line of the present utility model can also realize comprising impregnation method, double rubbing method and the impregnation technique such as rubbing method, double rubbing methods
Polyurethane PU synthetic leather semi-finished product produce, improve the scope of application of production line；Cloth is carried out through the technique of double rubbing methods
Producing, the product produced has more thickness sense, and texture is closer to corium；Owing to eliminating with acid displacement and washing acid solution
Process, directly dries water-base resin, causes the moisture that in drying course, cloth can volatilize to be far longer than prior art
The middle moisture volatilized through the cloth drying chamber of peracid displacement and washing acid solution, can not affect cloth by oven structure
On the premise of surface, cloth is effectively dried.
