Description
Technical field
The invention belongs to leather processing technique field, relate to a kind of leather wrinkling machine.
Background technology
Leather needs to carry out rubbing stricture of vagina with boarding machine in process of production, and rubs stricture of vagina process at present
In, main employing drum-type boarding machine, the mode of heating majority in cylinder is all to heat up slowly,
Take long enough after start can be only achieved and need temperature, thus cause work efficiency slow,
And the heat heated does not has recycling, waste resource.
Additionally during rubbing stricture of vagina, the cylinder of boarding machine is its core apparatus.Boarding machine at present
There is cylinder discontinuity, easily shake, problem that noise is big.Present artificial leather,
Synthetic leather manufacturer, to the surface wind of operation after artificial leather, synthetic leather artificial leather
Lattice arrange processing mode and are probably divided into two kinds, and one is that water rubs stricture of vagina arrangement, i.e. uses industry
Washing machine left rotation and right rotation, leather in a liquid along with machine left-right rotary then rolling, and
Rubbing forms lines each other, and water outlet is dried the most again, and dry rub is that leather is padded water
After, put small rotary formula baking oven into and carry out rubbing stricture of vagina, its principle be also by roller about
Rotate thus produce the rubbing between leather to produce lines.Although this kind equipment produces
The fidelity of product dermatine is high, and feel all can reach requirement, but due to by machine
The restriction made, during rubbing leather is, because the special tectonic of boarding machine, often
Individual picks and places product in the cylinder of boarding machine and bothers very much, generally require substantial amounts of manually
