Welcome to inquire or to plant negotiations!Technical specifications and requirements1, the design conditionsName: plastic shellMaterial: Plastic (ABS + PC+PP+PET+PE)Workpiece size: H100 Φ300mmDesign production: 3000 pieces / Hr (according to the conventional workpiece)Chain speed: 3-12m / min (continuous adjustable)Transmission: plane automatic transmission (about 75 meters across the board)Fixture spacing: 38.1mm, pin pitch 38.1mmSite area: L46 meters * W27 meters * H3.9 metersSpray method: fixed gun sprayHeating method: electric heatingCuring time: pre-bake 7 meters, 35 meters baking primer, UV homogenization of 25 metersPurification level: Painting area (spray room, bake Road, paint room,) for the 10,000 level, the other area of 10 million2, the processOn 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 outlinedThe 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 secondary pollution.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 curing.After-sales serviceMy company to fast, good after-sales service to win the trust of customers:Free debugging of products and technical training.Regularly maintain the equipment.Warranty period of one year, responsible for maintenance.Automatic spraying production line for different industries, plastic products industry, glass products, metal products, ceramic products, etc.
