Semi Automatic Manual Oil Filling Machine Cosmetic

NP-S semi automatic oil filling machine which We adopted advanced techniques and designed the NP-S series. Our products are handy in operation, precision adjustment, volume adjustment, maintenance repairs and so on.
We substitute pneumatic components for electricity control circuit in the NP-S series piston fillers, so it is especially suitable for explosion-proof.

1. Selection of types

We classify the types of NP-S semi automatic oil filling machine by the maximum filling volumes which most customers require.
NP-S are divided into 6 basic types as follows:
NP-S-3 (15~30ml)
NP-S-6 (15~60ml)
NP-S-12 (30~120ml)
NP-S-25 (60~250ml)
NP-S-50 (120~500ml)
NP-S-100 (250~1000ml)
NP-S-500 （500-5000ml）

2. Working principle

The working principle of our NP-S is explained as follows: the cylinder’s moving back and forth makes the piston reciprocate, thus, negative pressure is created in the front of the material tank.
Our NP-S has high precision and stability to every regular container, because each filling is a unitary and mechanical motion.

3. Features of NP-S

1) NP-S semi automatic oil filling machine is controlled with compressive air, so it is specially suitable for explosion-proof.

4. Checks before starting machine and sequence of operation

The content of checks and operations is as follows:
5) Turn on the air supply.

5. Adjustment of filling volume

The filling volume depends on the capacity (ml) or weight (g) that the user wants. Because the specific gravity of material ranges greatly, the same data on the survey meter may be not applicable for all materials. The distance control switch can be accommodated to obtain an exact data.
Detailed operations are as follows:
1) Rough adjustment: Move the adjustment screw left and right in order to regulate of advancement air control switch. Adjust the screw of backhaul air control switch properly to reach the satisfied position.
2) Place a measuring cup or a stuff bottle below the nozzle. (Notes: a full material tank ensures high accuracy and vice versa.) Put the cup or bottle onto an electronic balance to check out whether the filling volume is accurate.
3) If error still exists, it is essential to regulate the backhaul distance control switch through the handwheel. Filling volume increases when the adjuster slides left, and vice versa.
4) Adjust repeatedly until it reaches the proper filling volume and precision.

6. Adjustment of filling velocity

Filling velocity is decided by following 5 factors:
1) Velocity of material and length of intake pipe
2) Dimension of the nozzle. The larger the nozzle is, the faster filling will be.
3) The extent of foaming. You’d better slow down the velocity when filling foamy material.
4) How much to fill. Please fill at a low speed if the filling volume is large.
5) Filling precision. If you demand a high accuracy, filling velocity should be decelerated.
Tips for adjusting operation:
1) Loosen the adjustable nuts which fix the front and back speed control valve.
2) Turn the handle of the front one-way throttle valve clockwise, filling velocity slows down when the cylinder’s advance decelerates.
3) Turn the handle of the front one-way throttle valve anticlockwise, filling velocity speeds up as the cylinder’s advance accelerates.
4) Turn the handle of the back one-way throttle valve clockwise, inhaling speed decreases as the cylinder’s countermarch

7. Adjustment of filling precision

Filling error is mainly determined by filling volume, filling velocity, on-off frequency of the up valve and the down one. The on-off frequency is relative to the material viscosity. The more viscous material is, the lower on-off frequency is.
Modifying spring force can adjust the on-off frequency. If the spring force is increased, this frequency will be boosted.
You can get an appropriate spring force by measuring filling volume or with operator’s experience.

8. Maintenance and repairs

Before washing this machine, you’d better clean up all materials left inside it, afterwards fill moderate scour into the reservoir. We suggest you to use warm water. Surely, if necessary, suds, alcohol and other scour are available.
Make certain that all seals are at their working positions while washing. Keep this machine continuously running until it has been cleaned up. This simple manner is recommended if your demand is not strict. Or it is sure to thoroughly wash up all the parts contacting with the material, including cylinder, piston, seals, nozzle, hopper and so on. Firm that none seal is missed. Then change the broken and the worn-out seals.
