Plastics are a type of synthetic polymer material with plasticity. When plastic bottles are processed, they need to be painted. Currently, an efficient multi-color spraying production device for plastic bottles is required.

[0003] First of all, when the spraying production device is in use, the paint liquid is prone to caking. The existing spraying production devices usually do not have the function of preventing the paint liquid from caking during use. This easily leads to the phenomenon of caking of the paint liquid during the use of the spraying production device, shortening the service life of the paint liquid during the use of the spraying production device. Secondly, due to the different sizes of plastic bottles, the general applicability requirements for the spraying production device are relatively high. The existing spraying production devices have poor general applicability during use. This makes it inconvenient to clamp the plastic bottles at the designated positions according to the sizes of the plastic bottles when the spraying production device is in use, and easily leads to the phenomenon of deflection or displacement of the plastic bottles when the spraying production device sprays the plastic bottles, reducing the spraying effect of the spraying production device on the plastic bottles.
