2, the painting spray process
On the A line → manual dust removal → automatic dusting → preheating → spray primer (fixed 12 guns)
→ leveling (4min) → IR curing (80 ℃ 35m) → 5m cooling → topcoat (fixed 12 guns)
→ IR Homogenization (60 ℃ * 25m) → UV light curing (8-5KW) → cooling → lower → coating.
On the B line → manual dust removal → automatic dust removal → spray UV paint (fixed 12 guns)
→ IR homogenization (60 ℃ * 25m) → UV light curing (8-5KW) → cooling → Unloading.
3, the specific process outlined
The entire painting operation area (including the upper and lower parts) for the whole closed
decoration, staff entrance with the wind leaching room and the outside world partition, the region by
the strong supply of fresh air supply device after purification to ensure that its air cleanliness Not
less than 100000 level. After the work piece is taken out, the assembly workbench is arranged in the
room. The workpiece is manually assembled and then manually removed by electrostatic dust.
The workpiece is sent to the "spraying line" through the plane conveyor. Pieces of room ",
and then with the conveyor chain on the rule of plug. (Please note, the program used in the governance
of the special design, processing, and its rotation flexibility, easy to plug, is the industry's
leading technology). On-line workpiece into the automatic dust removal device before the first through
dehumidification drying section, the equipment is our company through continuous summary and
continuous communication with the user and specially designed, mainly to reduce the workpiece surface
humidity, to ensure the quality of the spray. Then the workpiece through the automatic addition to
electrostatic dust removal device, once again eliminate the residual electrostatic charge on the
workpiece and dust. In order to make each part of each workpiece can be completely dust, the conveyor
chain in the station with a self-rotation device, the workpiece in addition to automatic electrostatic
dust removal is carried out in the rotation, dust removal effect is good. We use the electrostatic
precipitator for the German products Si Dike licensing, a well-known brands. Pay attention to the
workpiece dust removal is a significant feature of this program.
After two dust removal of the workpiece directly into the spray chamber. Spraying room is an important
work area of the production line, the fresh air sent by the gas supply device through the 99.995%
efficient filter again after the fine filter into the spraying room; cleanliness of 10,000 or less,
the exhaust is Spray cabinet exhaust fan pumping to the roof. Before the exhaust emission, which
contains more than 80% of the paint mist has been spray cabinet and the vortex double handle the
collection, generally do not exceed the emission limit standard. The design of the indoor air flow
velocity of spraying is 0.6 ~ 1 m / s, in order to ensure safety, non-toxic, and no vortex airflow and
This program uses Japan's Iwata] [brand of automatic spray gun, the paint spit out a stable and
reliable, to ensure the quality of spray. Fixed spray gun is divided into two groups, is a turn, a
group of reversing, each with six guns, respectively, while the workpiece on-line spraying. In order
to obtain a uniform coating of the various parts of the uniform, the transmission chain in the
spraying station are equipped with forward and reverse rotation of the two devices (80 to 200 r / min,
frequency control), with the fixed gun match. When the photoelectric sensor to fixture to hang a
workpiece, the rotation device starts, and then set the spray conditions to start automatic spraying.
This kind of workpieces can be sprayed in rotation. As long as the rotational speed and spraying
conditions are properly set and matched, not only the obtained coating film is extremely uniform, the
quality is stable and excellent, and the coating is saved very much. This program selection of special
fixed gun and the conveyor belt with the rotation device to match, so that the conveyor and fixed gun
are fully coordinated with the work, the state is stable, complement each other, but also a major
highlight of the set of equipment.
The sprayed workpiece then enters the leveling section. The leveling section is provided with an air
supply device and an exhaust device to ensure that the paint concentration in the leveling room does
not exceed the explosion limit and ensure safety.
The flattened workpiece enters the drying Oven and is cured by electrical heating. Curing furnace
heating using hot air circulation form. The company's manufacturing oven not only looks beautiful, all
with stainless steel liner, not rust, suitable for regular maintenance of clean. Because the heating
pipe is evenly distributed, it is regulated by PID proportion type, the furnace temperature is stable
and uniform, and the instrument is equipped with automatic display and record the temperature of each
measuring point in the furnace, so as to record and visualize conveniently. Baking about 15 minutes
after the workpiece baked into the cooling section, after the fresh air cooling, to ensure the quality
of the paint UV coating, but also equipped with exhaust, timely discharge of hot air.
In the workpiece into the UV light curing machine before, have been IR homogenization, and its role in
the UV curing of the workpiece before the preheating activation of the coating molecules to ensure
the quality of UV curing. Followed by UV light curing. UV light curing machine according to set the
program boot. The company designed the UV light curing machine, adjustable workpiece and lamp distance.
To ensure that light curing time and set the energy are just right. At the same time, light curing
station conveyor chain is also equipped with rotation device to ensure uniform irradiation, uniform
