Self-painting has a wide range of uses. Through the economic development in recent years, in addition to graffiti, it has been used in many industries such as molds, industrial machinery, toys, handicrafts, musical instruments, buildings, steel structures, advertising, and signs. There are self-painting figures.
Self-painting
So, how is self-painting made and what equipment is needed? The following editor will briefly explain the production process and method of self-painting.
First of all, let’s talk about the principle of self-painting. Self-painting is to fill the diluted paint and gas into a tinplate can. There are generally two types of gas in tinplate tanks, one is filled with high-pressure compressed nitrogen, and the other is filled with low boiling point and critical temperature materials. The pressure of these materials in the tinplate tank is generally 0.6Mpa. In a liquefied state, after spraying some paint, they will vaporize to supplement the pressure in the tank, thus maintaining the pressure in the tank back and forth. The raw materials (paints) of self-painting are divided into oil-based and water-based paints. At present, most of them are mainly oil-based, and water-based self-painting is still in the development stage.
At present, the production process of self-painting is as follows: put the empty can on the conveyor belt and put the glass beads into the filling station, and realize quantitative filling at the filling station. The filling volume can be controlled by adjusting the metering cylinder. After the material is injected, the tank moves to the upper valve position, and the valve is placed on the steel tank mouth to complete the compression. After pressing, the additive gas is injected. Then move to the buckle nozzle and buckle plastic cover station. Among them, the processes of placing glass beads, upper valve, buckling nozzle, buckling outer cover, etc. can be done manually or by machine. You can freely choose according to the size and needs of the enterprise.
Next, I will introduce you to the self-painting filling equipment, combined with the differences in the scale of each enterprise, the editor recommends two equipment with different output for your reference.
1. Fully automatic aerosol filling machine
The whole machine is composed of filling machine, valve supporting machine, sealing machine and propellant inflator. The cylinder is used to push the bottle instead of the original manual push. The jog and automatic modes can be selected during the operation of the equipment, which is flexible and efficient. All processes are assembled on one workbench, and one person can complete all processes. It occupies a small area and saves labor. The daily output can reach 4000-8000 cans/day (8 hours calculation). This machine is suitable for small-scale production enterprises, enterprises with scarce manpower and low output requirements.
2. Automatic aerosol filling machine
The machine is composed of a bottle unscramble table, automatic filling machine, automatic valve filling machine, automatic sealing aeration machine, automatic weighing and rejecting, water leakage detection, automatic nozzle loading machine, automatic large capping machine, online inkjet printer, Sealing and packing composition. It can be equipped with automatic glass bead placing machine, labeling machine and tube labeling machine. The conveying system can be designed according to U-shaped rotary structure, saving space. The machine has high production efficiency, safety and reliability, simple operation, convenient maintenance, and a daily output of more than 20,000 cans. This production line is suitable for large-scale production enterprises with stable sales channels, or expansion-type production enterprises.
In summary, through the above explanation, I believe that everyone has a certain degree of understanding. If you are interested in self-painting projects, you can call us.
