The painting assembly line is a popular product in the assembly line market at present. The seven components of the painting assembly line mainly include: the front part? Cleaning equipment, powder spraying system, painting equipment, oven, heat source system, electric control system, hanging conveyor chain, etc. ?
1. Pretreatment equipment
? Spray multi-station pretreatment unit is a common equipment for surface treatment, and its principle is to accelerate chemical reaction by mechanical scouring. Oil removal, phosphating, water washing and other technological processes. The typical processes of spray pretreatment of steel parts are: pre-degreasing, degreasing, water washing, water washing and surface treatment. Adjusting, phosphating, washing, washing and pure washing. Shot blasting machine can also be used for pretreatment, which is suitable for steel parts with simple structure, serious corrosion and no or little oil. And has no water pollution. ?
2. Powder spraying system
? The cyclone+filter element recovery device in powder spraying is an advanced powder recovery device with fast color change. The key part of the powder spraying system? It is suggested that imported products should be selected, and all parts such as powder spraying room and electric mechanical elevator should be localized. ?
3. painting equipment? The paint spraying produced by Suzhou Huqiang Company adopts oil spray booth and water curtain spray booth, which are widely used in the surface coating of bicycles, automobile leaf springs and large loaders. ?
4. Oven
? Oven is one of the important equipments in coating production line, and its temperature uniformity is an important index to ensure coating quality. Adding to the oven? Thermal modes include: radiation, hot air circulation and radiation+hot air circulation, etc. According to the production program, it can be divided into single room and through type, etc. What are the equipment forms? Straight-through and bridge. The hot air circulating oven produced by Suzhou Huqiang Company has good thermal insulation, uniform temperature in the oven and less heat loss. The internal temperature difference is less than 3 oc, reaching the performance index of similar products in advanced countries.
5. heat source system
? Hot air circulation is a widely used heating method at present, which uses the principle of convection conduction to heat the oven to achieve the dryness of the workpiece. Drying and curing. The heat source can be selected according to the specific situation of users: electricity, steam, gas or oil. Can the heat source box be based on the oven? Depending on: placed at the top, bottom and side. The circulating fan of heat source produced by Suzhou Huqiang Company is a special high-temperature resistant fan, which has the advantages of long life, low energy consumption, low noise and small size. 6. Electronic control system?
the electrical control of painting and painting assembly line has centralized and single-row control. Can the centralized control be controlled by PLC? Make the host computer, and automatically control each process, collect data, monitor and alarm according to the compiled control program. Single-row control is painting production? The most commonly used control method in the line is that each process is controlled in a single row, and the electric control box (cabinet) is set near the equipment, which has the advantages of low cost, intuitive operation and convenient maintenance. 7. Hanging the conveyor chain?
The hanging machine is the conveying system of industrial assembly line and coating line. The stacking hanging machine designed and manufactured by Suzhou Huqiang Company is used in? L=1-14M storage shelves and special-shaped street lamp alloy steel pipe coating line. The workpiece is hoisted on a special hanger (bearing up to 5-6KG). In and out of the turnout is smooth, and the turnout is opened and closed by electric control according to the work instruction, which meets the automatic conveying of the workpiece at each processing station. The cold room and the lower part area are cooled in parallel, and a hanger identification and traction alarm stop device is set in the strong cold area. What is the stacking type suspension conveyor? , has the advantages of low cost (about 1/3 of domestic similar products), heavy load bearing and space saving.
