How much do you know about the process layout of coating equipment?

Time:2024-05-29 Views:

The quality of the design of the coating equipment process layout is crucial to the use of the coating production line. If the process layout of the coating equipment is improper, even if the individual equipment is made well, the entire coating production line will not be easy to use.

1. The output does not meet the design guidelines: some designs do not consider the hanging method of the coating equipment, the hanging distance, the uphill and downhill, and the horizontal turning interference, and the production time does not consider the scrap rate, the utilization rate of the coating equipment, and the product. Peak production capacity. As a result, the output fails to meet the design guidelines.

2. Insufficient process time for coating equipment: Some designs achieve the goal by reducing process time in order to reduce the cost. Common examples include: insufficient pre-treatment transition period of the coating production line, resulting in liquid skewing; 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 The workpiece is overheated during the lower part).

3. Improper design of conveying equipment: There are many ways of conveying workpieces, and improper design will have undesirable consequences for production capacity, process operations, and upper and lower parts. Suspended chain conveying is common, and its load capacity and traction capacity need to be calculated and interfered with drawing. The speed of the chain also has corresponding requirements for the matching of equipment. Painting equipment also has requirements for 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 has its advantages and disadvantages. The design cannot be explained to the user, and it is found to be very unsatisfactory after manufacture. For example, air curtains are used to insulate powder spray drying tunnels, and cleanliness requirements are not installed with purification equipment. This type of error is the most common error in the process layout of coating equipment.
