二、Notice of all kinds of leather spraying machine
1、Heat by steam
1）If it is more than 7 sets, please make 2 groups with 4 sets (or 5 sets) each.
2）The connection frame should make space(80cm) to let one person through
3）If it is grouped in two groups, another spare parts should be added such as membrane valve, trap and pipe etc.
4）Attention please do notplace and install a lobe in a whole drying room or it will disturb the ropes.
2、Heat by conduction oil
1）It also uses the steam radiator as if it is heated by steam.
2）Differences between heat by conduction oil and steam
（1）The steam is sealed and driven out by trap.If it is heated by conduction oil, the steam is rotated and recycled by heat exchanger.
（2）The controlling valve is different. (We use pneumatic control valve at present.)
3、Heat by electricity
1）We use quartz tube at present for electricity way of heating. It is installed under the fan cover. It can be with recycled wind or direct eradiate.
（1）If it is with recycled wind, a fan cover is necessary also the cover should open a hole for wind.
（2）If it is radiated, there is no need to a cover with a hole.
（3）The wire is thick and hard so the trunking must be wide enough.
（4）If it is heated by electricity, the heat concentrates under the cover. Please place the temperature sensor equal with the lampshade.
（5）Please attention the connection of the electricity box and choose right power of equipment.
5）Usual power of heating by electricity
180-240：8-10kw each set；
240-280： 12-14kw each set；
300-340： 16-18kw each set；
(Notice: In the south, it can be lower, in the north, it can be higher.)
4、Heat by diesel oil
1）The difference between heated by diesel oil and by steam is that the first one does not need steam radiator. The hot wind is transferred by pipe and fan to the leather.
2）Notice for heat by diesel oil
（1）All the pipe should be covered with high temperature resist materials.
（2）All the electric wires should be away from the pipe for hot wind.
（3）Before installation, we need to know where to install such as on the top or on the ground.
5、Heat by steam and electricity mixed
1）It is the same to heat by steam, but the electric device is under the cover of diffusers.
2）Others please refer to that heat by steam
6、 Transmit by nylon wire
1） There are two kinds of nylon wire at present.
（1）One is with line washing system. The two sets of wire are separated.
（2）One is without line washing system. There is totally one set of wire.
2）Attention that the tooth divider should be adapted with roller. Before shipment, it should be corrected with the channel of roller.
3）Usually for nylon wire transmission, there is no need of euphroe however if you need, it can be placed before the entry of spraying.
7、Transmit by teflon
1）Teflon leather spraying machine
（1）There must be a retractor.
（2）The retractor must be placed on the outside of the leather.
（3）The main roller on the Teflon could be 1# smaller than the nylon wire transmit.
（4）The error correcting device should be placed at the entry.
（5）Each set of drying room must be equipped with two carrier rollers.
2）Drying room for coating machine with Teflon transmit.
（1）Attention that error correction device should be placed at the entry side of leather without cold wind.
（2）There must be a tighten device after the exit.
8、Transmit by steel wire
1）There must be a tighten device at the entry side.
2）The roller should be thicker than standard one.
3） Washing line and squeegee is not allowed.
4）The steel wire is hot galvanized.
9、Washing line with brush
1）The washing channel should be designed easy to be taken in and out.
2）The diameter of pipe for water out should be large enough and easy to be installed.
3）The channel should be checked to insure it would not leak.
10、Washing line with washboard
The washing line with washboard must be installed at the exit of the leather. Some is installed in the middle of the washing system. For different places installed, the requirement is different.
The requirement if it is put in the middle of the equipment.
（1）The washboard at both sides should be made by steel.
（2）The deconcentrator should not be placed near the washboard.(>10cm)
（3）The brush should not be too hard or it will pull down the machine.
（4）The swing and lift and down should be adjusted.
2）The requirement for washboard placed at the exit of the leather.
（1） There should be a stainless platform under the washboard.
（2）The fur on the brush could be soft or hard.
（3）Others please refer to above requirements.
11、 squeegee board
1）The squeegee board is for nylon wire, but it can also be placed for washing line system.
2）The squeegee board is usually placed at the exit of the leather.
2）Notice: the teeth on the squeegee board should be able to put up and down.
12、Rotation type of spraying
1）Notice if it is one way or two ways of spraying. If it is the two ways of spraying, there should add spray guns and solenoid valves. The axis should be two ways of slurry. There needs two pumps, two bases for pump, two hooks and more pipes for air.
2）Notice if it is one gun with two pumps. If it does, the axis should be two ways spray and it needs two spray pumps.
3）Notice if the customer requires patterns. If it does, a solenoid valve is needed.
4）The top of the spraying booth must be opened with many holes all around. The more, the better.
13、Spray back and forth
1）Attention: the inside casing and the spraying room must be 5cm away from each other to avoid shake.
2）The back and forth motor should be variable frequency motor with cold wind because the ordinary will be burned for back and forth way.
3）The travel car should be made of steel. Aluminous is not allowed.
14、 Rotation and back and forth mixed
1）Because the spraying room is very long, there should be two holes for dedusting, one long water tank, and one fan with large power or two small fans.
2）Others please refer to rotation and back and forth type.
15、Guns with different sizes
