Technical Field

[0001] The invention relates to the technical field of coating production unloading, and in particular to a coating production unloading device. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. The appearance, various mechanical properties and corrosion resistance of the paint film formed by this kind of coating can meet the requirements of automobile finishing.

[0003] At present, in the process of unloading powder coating production, the unloading amount is usually monitored manually, that is, a weighing device is installed under the storage container, and when the weight of the coating dropped into the storage container from the discharge port reaches the specified weight, the personnel closes the discharge port to achieve quantitative discharge. This method not only consumes a lot of staff's energy, but also has the problem that the operator closes the discharge port at different times each time, and there will be errors in the discharge amount each time, making it impossible to achieve accurate and fixed discharge amount each time.
