Problems solved by technology

[0004] The present invention provides a vertical intelligent multi-directional electrostatic spraying method, which can effectively solve the above-mentioned background technology. At present, when the product is electrostatically sprayed, the product is generally sprayed directly, resulting in the product not being preheated, so that the product is sprayed. There will be some cases where the adhesion speed is slow, and at the same time, the high-temperature drying is carried out directly after the spraying is completed, which makes the product's instantaneous contact temperature too high, resulting in insufficient steam exhaust rate, causing the coating to be thermally peeled off, thus affecting the quality of the product The problem

Embodiment

[0047] Example: such as Figure 1-15 As shown, the present invention provides a technical solution, a vertical intelligent multi-directional electrostatic painting method, comprising the following steps:

[0048] S1: Product preheating: it is supported by the support frame 1, and the internal heat is supplied through the intake pipe 502, and the angle of the flow-limiting disc 507 is controlled by the adjusting electromagnet 508, so as to facilitate the control of the gas flow rate and ensure the heat exchange time ;

[0049] S2: Product rotation: The product is supported by the limiting inner hole rod 307 and the fixed support plate 312, and the gap difference between the air inlet and outlet is used by the accelerating fan 317 and the air inlet box 318, so that the airflow always flows at an angle, driving The product is rotated;

[0050] S3: Electrostatic spraying: Spray the rotating products through the internal electrostatic spraying gun;

[0051] S4: Paint drying: Hea...

Abstract

The invention discloses a vertical intelligent multidirectional electrostatic paint spraying method. The vertical intelligent multidirectional electrostatic paint spraying method comprises the following steps: S1, product preheating, S2, product rotating, S3, electrostatic spraying, S4, paint drying, S5, heat flow recovery and S6, surface protection. According to the invention, products are preheated, so that the situation of non-uniform electrostatic charge distribution caused by direct spraying for the cold products is avoided, and then the uniformity of the products during spraying is ensured; by rotating the products, excessive paint is prevented from being accumulated on the surfaces of the products, and then orange-stripe-shaped stripes on the surfaces of the products caused by flowing of the paint are avoided, so that the spraying quality for the products is ensured; the products are subjected to hot drying after the spraying is completed, and through symmetrical hot drying at the two ends, the paint is prevented from flowing during the hot drying, so that orange-stripe-shaped flowing marks are further avoided while paint distribution is ensured; and meanwhile, the products gradually adapt to different temperatures through multi-step hot drying, so that hot stripping caused by instant high temperature is avoided.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a vertical intelligent multi-directional electrostatic spraying method. Background technique [0002] The atomized paint particles are negatively charged in the DC high-voltage electric field. Under the action of the electric field, the paint particles fly to the surface of the positively charged workpiece to form a paint film. This process is called electrostatic spraying. Electrostatic spraying is based on the object to be painted. The positive electrode, the paint atomization device is the negative electrode, following the principle of "same sex repels, opposite sex attracts", the charged paint medium is under the action of electric field force, the paint forms an enveloping effect on the coated object, and flows in a directional direction along the electric force line The surface of the coated object with positive charge is deposited into a layer of uniform and...
