PLC Programmable Controlling High tolerance Bath Pre-expander less3% error

,

Feature:

The expanding process is the most important step in producing EPS cushioning

and thermal insulation material.
If large quantity and uniformity of products can be produced in unit time,

it will reduce costs of material and energy to a large extent.
To shorten cycler time, reduce steam consumption and produce high quality products,

it should choose pre-expander machine carefully.
This type of pre-expanding machine is designed with below-discharging,

which avoids material extrusion or deform of discharging door

and could save much more energy.
The material weighing system minimizes volume variations

through the use of a load cell and indicator.
A level master sensor maintains an exact rise of

expanding material reducing density variations through the expanding.
Heat controller is applied during discharge of the vessel to reduce water entertainment,

eliminating thermal shock and creating energy savings.
If there is an electrical interruption during the expansion cycle,

steams is cut-off and air is automatically aplied to the expander chamber,

preventing freezing up of EPS particles.
Our new advanced touch screen control system allows easy operation,

it also has self checking, warning, position indicating and troubleshooting system.

Application:

1. The machine adopts PLC programmable controlloer and

touch screen control,automatic feeding,

automatic electronic measurement,

automatic contorl of temperature and

pressure,dry barrel drums,etc.,

have made the material once completed,

to ensure that the machine automatically cycle of production.
2. The use of electronic weighing systems,

photoeletric material level control system,

proper grasp bulk density foam material,

so that a uniform density foam beads

after each error is less than 3% or less.

3. Barrel body temperature and vapor pressure,

the use of advanced high-precision Japanese pilt valve control,

ensure that the pressure relief valve outlet is always constant,

ensure that the temperature inside the tank advance machine control within ±1% °c of,

so as to ensure the consistency of raw EPS issued prevent EPS material

because the temperature control is not good agglomeration.

4. Automatic vacuum feeding device,

electronic weighing devices,

combined with level switch to achieve the automatic feeding,

improved production efficiency,reduce labor inensity.

5. The barrel constant use of closed foam,

high thermal efficiency,

save steam energy than the continuous

advance machines save more than 50%.

6. The aircraft is equipped with a high quality enclosed hot air drying system,

good raw material in the barrel body hair dry,

without going through along curing dry bed.

Weighing system on top of the barrel,

so the small footprint and compact machine structure.
7. The machine uses electrical,pheumatic components,valves,etc.

are well-known brand products,

thus ensuring the operation of the machine stability,reliability and long service life.
Automatic discharge barrel using compressed air to blow the material ,

increase the feed rate.
8. The computer has a memory function,

can often use the EPS raw material manufacture brands,specifications,foaming process,

all parameters can be recorded in the computer.

When you need to use the manufacturers of raw materials used in the past,

you just press a computer touch screen can quickly go back to the original process.
9. The machine is suitable for high altitude areas of foam production,

play a pressure foaming machines superiority

(In the same environment Continuous Pre machine productivity is very low.)
