Problems solved by technology

However, when dipping, the inside of the object or the concave and convex parts on the surface will be caused by the existence of air bubbles, and some parts cannot be painted
In addition, when objects are immersed in paint, the paint is often applied unevenly due to the different shapes and roughness of each part.

Embodiment 1

[0025] Such as figure 1 The ultrasonic paint dipping device shown includes a container 1 for placing paint, and an ultrasonic generator 2 for emitting ultrasonic waves to the paint.

[0026] As a further improvement, the ultrasonic generating device 2 is an ultrasonic vibrator.

[0027] As a further improvement, the container 1 is placed in the heating device 3; a heating medium is added to the container 1 and the heating device 3.

[0028] As a further improvement, the heating medium is water.

Embodiment 2

[0030] A kind of ultrasonic paint dipping method, comprises the steps:

[0031] Step 1, preparing the paint, adding the paint to container 1;

[0032] Step 2, heating the paint to 15°C-30°C;

[0033] Step 3. Adjust the paint viscosity to 20P-50P;

[0034] Step 4, blanking and dip coating: put the items to be painted into the paint;

[0035] Step 5. Turn on the ultrasonic device and perform ultrasonic vibration. The frequency of the ultrasonic wave is preferably within 20k-50k Hz, preferably 40K Hz; the ultrasonic device is an ultrasonic vibrator with a power of 50W-250W and a time of 2-30min. It is 7min.

[0036] Step 6. Material removal: take out the painted items;

[0037] Step 7. Drying: Dry the painted items.

[0038] When the material is dipped into the paint and the material is lifted out of the paint, the inclination angle of the object to be painted is 25°-55°.

Abstract

The invention discloses an ultrasonic paint dip-coating method and device. The ultrasonic paint dip-coating device comprises a container containing paint and further comprises an ultrasonic wave generating device emitting ultrasonic waves to paint. The ultrasonic paint dip-coating method comprises the following steps that firstly, paint is prepared and fed into the container; secondly, the paint is heated; thirdly, the viscosity of the paint is adjusted; fourthly, feeding and dip-coating are conducted, wherein an object needing to be painted is placed in the paint; fifthly, the ultrasonic wave generating device is switched on, and ultrasonic shake is conducted; sixthly, material discharging is conducted, wherein the object coated with the paint is taken out; and seventhly, drying is conducted, wherein the object coated with the paint is dried. According to the ultrasonic paint dip-coating method and device, because the ultrasonic waves are adopted in the paint dip-coating process, bubbles are prevented from hindering paint dipping, and paint dipping is uniform and good in effect.

Description

technical field [0001] The invention belongs to the field of dip coating, in particular to an ultrasonic paint dip coating method and device. Background technique [0002] The surface of many items needs to be painted to achieve anti-corrosion, moisture-proof, moth-proof and other effects. Some methods of painting are to smear on the object surface with a brush, but the paint layer in this way is uneven, and is only suitable for planes, and can not be painted inside the article. In order to paint an uneven object, or to paint the inside and outside of an object, dip coating is usually performed by soaking the object in paint. However, during dip coating, the inside of the object or the concave and convex parts on the surface will be caused by the existence of air bubbles, and some parts cannot be painted with paint. In addition, when the article is immersed in the paint, the paint is often applied unevenly due to the different shapes and roughness of each part. Contents ...
