Description

A paint spraying machine

technical field

The utility model belongs to the field of spraying machinery, in particular to a paint spraying machine.

Background technique

Spraying machine is a kind of coating equipment. The principle is to disperse the paint into mist and spray it on the surface of the sprayed workpiece. It is suitable for the surface spraying processing and production of various products such as hardware and plastic parts.

At present, water curtain spraying machines are mostly used in the traditional spraying industry. The bottom of the water curtain spraying machine is a pool, the front is a spraying studio, and the rear is a spray room. It uses a water pump as the power for water circulation and spraying. Water curtains are formed on one or three sides of the spraying studio, and spray is formed in the spray chamber. The excess paint mist generated during spraying will flow into the pool with the water flow when encountering the water curtain, and the rest of the paint will be sucked away by the exhaust fan and sprayed Room was cleaned again. During the spraying process of the water curtain spraying machine, the excess paint is washed into the water. Even if it is dry sprayed, it cannot be collected and reused. The paint utilization rate is only about 40%, which is low and causes a lot of paint waste. The production cost is increased, and the waste water and air permeated with paint seriously pollute the environment.

Furthermore, the bottom of the spraying studio is provided with a receiving pipe for receiving the paint flowing down from the filter layer.

In addition, an air supply filter for filtering dust and impurities is provided above the spraying studio.

The beneficial effects of the utility model:

The utility model has a reasonable structure, and a multi-layer paint filter layer is set between the spraying studio and the exhaust fan, which can collect the excess paint in the spraying process, greatly reducing the paint entering the air and reducing air pollution. After being filtered by the filter layer, it can be collected and reused after treatment, which greatly reduces the production cost, and does not generate waste water, greatly reducing environmental pollution.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the structural principle of the utility model will be further described in detail below in conjunction with specific embodiments and accompanying drawings:

As shown in Figures 1-5, a paint spraying machine includes a frame body 1, a spraying studio 2 for spraying workpieces is provided in the frame body 1, and an air supply filter for filtering dust and impurities is provided above the spraying studio 2. A device 9 is provided with an exhaust fan 3 on the frame body 1, and the exhaust fan 3 communicates with the spraying studio 2 through the exhaust pipe 4, and a filter layer 5 is provided between the spray studio 2 and the exhaust fan 3 in the exhaust pipe 4 , the filter layer 5 is used to filter and recycle the unused excess paint when spraying the workpiece. When the exhaust fan 3 starts to work, the air outside the spraying studio 2 enters the spraying studio 2 after being filtered by the air supply filter 9, which ensures the cleanliness of the air in the spraying studio 2, and the exhaust fan 3 will be in the spraying studio 2. The air that has paint spray is exhausted in the air from the air outlet of exhaust fan 3 after filter layer 5.

Wherein, above-mentioned filter layer 5 comprises the first filter layer 51, the second filter layer 52 and the 3rd filter layer 53, and the first filter layer 51 is installed in the exhaust duct 4 of spraying studio 2 lower front sides, the first filter layer Layer 51 is a steel plate, and the steel plate is provided with micropores that run through the surface of the steel plate; the second filter layer 52 is installed in the exhaust pipe 4 on the side of the spraying studio 2, and the second filter layer 52 is a steel part.
