If you want the use ratio of paint coating equipment can reach high standard，must establish reasonable painting production lines. First, determine the production program, improve the process design, and plan planning, and then design, manufacture and install the equipment. Therefore, process design and program planning are the basis for establishing a production line, and a correct and reasonable process will have a decisive impact on production operations and product quality.
Process layout of coating equipment:
1. The output fails to meet the design guidelines: some designs do not consider the suspension method, suspension distance, up and down slopes, horizontal turning interference, production time, scrap rate, coating equipment utilization, and peak production capacity of the coating equipment. As a result, the output fails to meet the design guidelines.
2. The process time of coating equipment is not enough. Some designs achieve the goal of reducing costs by reducing process time. Common ones such as: insufficient pre-treatment transition period of the coating production line, leading to liquid cross-flow; heating time is not considered during curing, resulting in poor curing; insufficient spray leveling time, resulting in insufficient film leveling; insufficient cooling after curing, spray paint (or lower part) ) When the workpiece is overheated.
3. Improper design of conveying equipment: There are various ways of conveying workpieces, and improper design has adverse consequences for production capacity, process operations, and upper and lower parts. Suspended chain transport is common, and its load capacity and traction capacity require calculation and interference drawing. The speed of the chain also has corresponding requirements for the matching of the equipment. Painting equipment also needs the stability and synchronization of the chain.
4. Improper selection of coating equipment: Due to different product requirements, equipment selection is also different, and various coating equipment have their advantages and disadvantages. Moreover, the design cannot be explained to the user, and it is found to be very unsatisfactory after manufacture. For example, the powder spray drying tunnel is insulated with air curtains. No purification equipment is installed on the workpieces with cleanliness requirements. This error is a common error in the process layout of coating equipment.
