POWDER COATING MACHINE

Brief description

After-printing corollary equipment which substitutes traditional handwork. This machine is convenient to apply, high effective, flexible, and free of contamination, which both increase productivity and raw material utilization, as well as producing beautiful pictures.

In this machine, parts for key position such as powder sucking, transducer are imported with the advantages of durable and stable. Especially, this machine works well with those have high requirement of paper, film, glitter, and hot melting powder. All the drives in this machine are infinite speed variation. If required, it can also connect with drying equipment and UV photo-cure equipment.

Main Technical Parameters:

Read manual carefully, before operate the machine. Do not adjust any of button before connect to electric power.

Operation Manual

Warmly reminder: The powder will not scattering until the film pass  the sensor. 

This machine is equipped with separated switches for both power sucking upward and downward, as well as switches for delivering, dusting, powder feeding, and electrostatic neutralizer.

Start-up procedure

1. Switch on main power on the left case.
2. Turn on the power switch (See picture II-2).
3. Switch on upward power sucking motor (See picture II-8), and justify the frequency of transducer to 38-42HZ .
4. Switch on downward power sucking motor (See picture II-11), and justify the frequency of transducer to 55-65HZ.
5. Switch on the delivery power(See picture II-4), and adjust switch to 20-65HZ.
6. Switch on the powder feeding adjustor (See picture II-15), and adjust switch to 20-65HZ.
7. Pour hot melting powder into the dust tray, and then switch on dusting motor (See picture II-17). First, adjusting the speed of dusting (the faster, the more powder). Or adjusting the three nuts under the dusting funnel (See picture I-4) to justify the amount of powder, so that to meet the product’s requirement for powder thickness and balance.
8. Powder collector on the left case (See picture II-21) has the function of promoting powder-cycling. Usually, it is switched range from 60 to 70.
9. Open the electrostatic neutralizer switch (See picture II‐13)

Adjust machine

1． Adjusting the space between powder sucking upward and downward to 2‐3mm.

If there is still gear wheel on the sample while operating (usually, it has been already adjusted before rollout), you can fine‐tune the height for power sucking upward to meet product’s requirement.

1.1 Release four nuts at the corner. Reminder: Adjust height only after release the four nuts. (See picture )

1.2 Release the nut (See picture 1), fine-tune the height for power sucking upward (See 1, 21,22). Or (See picture 1) Turn clockwise the gap getting close. Turn anticlockwise the gap getting wide.

1.3 Fine-turn four nuts at powder sucking area, make it balance. (See picture 1) Tighten the black screws (See picture 1)

Powder recycling process

1.If there is powder residue on the product, it is better to fine increase the speed of powder sucking upward motor (See picture Ⅱ-8). However, higher air flow can also cause paper jamming, adjust smoothly.

If there is still powder residue on product, after increase the speed of powder sucking upward, check the height of upward and downward. If the gap is too wide, follow the previous step to adjust the height.

Check the dusting bag without powder to block the air hole. According to the thickness of powder, it is necessary to clean the dust bag to avoid blocking up the air hole.

Check the bottom side of the machine, make sure the powder recycling assist system on.

Regulation of the amount of shaking powder

1. Adjust the powder shake speed controller (See picture II‐22).

       2. Adjust the powder shake speed controller (See picture II‐22) still not reach your demand. Could adjust the screw on the left of cage(See picture ).

Process for power off

1. switch off the regulator of dust tray (see picture II -17)
2. Shut down the regulator of shaking (see picture Ⅱ-22)
3. shut down the switch of power sucking upward (see picture II-7)
4. shut down the switch of power sucking downward (see picture II-10)
5. shut down the switch of delivering (see picture II-4)
6. switch of the switch of  (see picture II-21)
7. switch of the regulator of powder delivering (see picture Ⅱ-15)
8. shut down the switch of main power (see picture II-2)
9. Clean the control panel and cover it with dust jacket 

Machine attendance

1. After operating for a period, open the baffle, and fill those active parts with 20# engine oil. If the chain is slack, use the elastic gear to adjust.

2. While replacing raw material such as glitter and hot melting powder, use compressed air to clean all these parts to avoid powder mixed.

3. According to the thickness of powder, it is necessary to clean the dust bag to avoid blocking up the air hole.

Operation empty machine

Turn switch on for machine rise (See picture 3). Turn the switch on the top half part of machine will rise up, otherwise come down.

Turn the delivery switch to automatic (See picture II-4), and shut down all other switch, make pre-heating film pass by.

Fault Resolution

1. Please replace speed governor while it doesn’t work.

2. Please follow the instruction in Machine attendance if the powder is not suck up completely as before. Or you can also increase destaticizer to deal with this problem.

3. Please check the powder whether they are clean and dry if dusting in difficulty. If the powder is wet, please insolating them under the sun.

4.If powder recycling tube block, Please check the bottom of the frame turn the residue assistant system on. Or Check the powder sucking downward, make sure it running.

5.Turn the switch on the top half part of machine will rise up.
