Plastic spraying equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment and other coating equipment powder coating production line mainly consists of pretreatment electrophoresis line, sealed bottom coating line, middle coating line, top coating line, finishing line and its Drying system composition.
Plastic spraying equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment and other coating equipment. The whole-line workpiece conveying system of the painting production line adopts a mechanized conveying method that combines aerial suspension and ground skid. The operation is stable, fast and convenient; PLC can be used Control programming, programming control according to the actual requirements of the production process-the implementation of field bus center monitoring, and the partition automatically realizes the transfer operation.
The types and characteristics of the powder coating line, such as plastic spraying equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment, etc. are as follows:
I. Plastic spraying equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment and other coating equipment disc synchronous assembly line Features: The typical structure is a disc. Operated by cam, 4~24 work, simple structure, less investment, reliable, high precision, high productivity, durability, and less space occupation. The assembly space is limited, the process is limited, the operating speed is determined by the slowest process, and any process failure will cause the whole machine to stop running and have low flexibility. Applicable occasions: the number of processes is small; the product has a large and stable batch; the time of each process is similar.
2, spray equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment and other coating equipment straight synchronous assembly line Features: usually driven by a cam-operated indexing device, the transmission method can be divided into circular water surface type and upper and lower tracks Type, conveyor belt is usually chain or steel belt type. In recent years, the conveyor belt joint parts have been replaced by precision machined parts and stamped parts, and are connected by ball bearings. The number of continuous processes is large, simple, reliable, reasonable precision, durable, large assembly space, the speed of movement is determined by the slowest process, any process failure will cause the whole machine to stop running, low flexibility, cost and floor space are more than discs Rotary transmission mechanism. Applicable occasions: the number of processes is more than the disc rotary assembly mechanism; the operation can be arranged on both sides of the product, and the product has a large and stable batch; the time of each process is similar.
3, the characteristics of the conveyor belt plate type non-synchronized flexible powder coating production line: the precision pallet is driven by the production conveyor belt between the stations. In recent years, the application of less expensive commodity parts has gradually been widely used. The flexibility is much higher than the synchronous assembly line; the number of processes is not limited; this automated production line is easy to combine between a single process and multiple processes, adapt to different products in the product family, easy to combine manual and automatic processes, easy to gradually realize automation, relatively not It is easily affected by changes in other processes. When there is a storage area, a short-term failure of a process will not affect the work of the entire system. It has a large assembly space and has fixed transmission parts. The speed is low (generally 20 operations per minute), the equipment cost per unit product is high and the space is large. Applicable occasions: high flexibility requirements; low productivity requirements, a set of systems to complete the assembly of a family of products, product structure characteristics change moderately; the number of processes, the time of each process is not similar.
4. Plastic spraying equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment and other coating equipment balance beam plate type non-synchronized flexible assembly line Features: the pallet moves at high speed, and the balance beam module can be a single block or multiple blocks, a single channel Or multiple and unloaded in the buffer area, the balance beam positions the pallet at the short pin of each process, and the longer process is carried out in the buffer area. The flexibility is much higher than that of the synchronous conveyor. It has high productivity and high positioning accuracy. The number of processes is not limited. It is easy to adjust the number of processes. The use of the transmission control system can adapt to the assembly of different product families. It is easy to combine manual and automatic processes. When there is a storage area, a certain station failure will not affect the continuous operation of the entire system. This type of automated production line has a large assembly space. There are shaped transmission parts. At the beginning, the equipment started to invest a lot and occupied a large area. Applicable occasions: high flexibility requirements; low productivity requirements, a system to complete the assembly of a family of products, high assembly accuracy and product performance requirements; moderate changes in product structure characteristics; many processes, the time of each process is not similar
5, continuous motion transmission assembly line Features: continuous motion transmission assembly line products are assembled when moving, the typical motion is uniform speed, all parts maintain the same speed and accurate relative position. The speed is extremely high, suitable for all mechanical assembly operations. When multi-component assembly, accurate calibration is very complicated, the initial investment of equipment is very large, the maintenance of multi-component assembly is difficult, and the system is difficult to change or convert. Applicable occasions: the continuous motion transmission assembly line has a large production volume; the product is very stable, the number of parts is small; and the flexibility requirement is not high.
6. Plastic spraying equipment, electrostatic coating equipment, spraying equipment, electrostatic powder coating equipment and other coating equipment robot assembly units Features: The typical structure of this automated production line includes a robot, parts feeding device, work station, tools, Frame and control, can connect multiple robot assembly units through the buffer area to form a more complex system, high flexibility, easy to change and convert, can complete complex movements economically, can complete many continuous operations, high precision, reliable, mechanism It is complicated, takes up less space, and is generally slower. If multiple robotic assembly units are used to increase productivity, the investment is large. Applicable occasions: This type of automated production line requires high flexibility; the productivity requirement is not high, and a set of systems can complete the assembly of a family of products; often it is necessary to change the product reliably and quickly; the product structure characteristics change moderately; the assembly accuracy and product consistency requirements are high; The movement is complicated in some stations.
The design of each drying system of the powder coating production line of the spraying equipment, electrostatic coating equipment, spraying equipment, powder electrostatic spraying equipment and other coating equipment refers to foreign design concepts and parameters. The drying tunnel chamber body adopts a bridge structure ( (Except for the sealed bottom coating furnace), it guarantees the uniformity and stability of the furnace temperature and improves the efficiency of heat energy; the heating device introduces the products of the Canadian Comaco company, and uses imported burners and control systems. It is currently tested The drying systems are running well and stable, and the temperature curve is smooth and continuous, which fully meets the current process capacity requirements and can meet the requirements of increasing production capacity in the future.
