Spraying production line

Abstract

The invention discloses a spraying production line and relates to the technical field of devices for coating liquid or other fluids on surfaces. The spraying production line comprises a paint spraying booth with a vent pipe on top. A plurality of paint spraying stations are arranged in the paint spraying booth, and each paint spraying station is provided with a water curtain cabinet. Each water curtain cabinet comprises a water overflowing groove with an overflowing plate and a water curtain plate. Each water curtain plate is provided with two opposite water curtain auxiliary plates, and a water curtain main plate is connected on the same sides of the two water curtain auxiliary plates. Each overflowing plate is provided with an overflowing main plate corresponding to the water curtain main plate and overflowing auxiliary plates corresponding to the water curtain auxiliary plates, connecting main plates are arranged between the overflowing main plates and the water curtain main plates in an inclined mode, and connecting auxiliary plates are arranged between the overflowing auxiliary plates and the water curtain auxiliary plates in an inclined mode. A water washing chamber communicated with the vent pipe is arranged on one side of each water curtain main plate. Compared with the prior art, the water curtain main plate and the water curtain auxiliary plates are arranged on three lateral sides of each paint spraying station, water film area for absorbing paint mist is greatly increased, absorbing capturing capacity of the paint mist is improved, paint mist processing speed is high, and the environment is protected from being polluted.

Description

technical field [0001] The invention relates to the technical field of devices for coating liquid or other fluids on surfaces, in particular to a spraying production line for surface coating of auto parts. Background technique [0002] Spraying is to cover metal and non-metal surfaces with a protective or decorative layer, and the spraying station is one of the important stations of the spraying production line. In the air; therefore, in order to protect the health of the operator and prevent paint mist from polluting the environment, the spraying station must be equipped with a water curtain cabinet and an air supply and exhaust device to meet the needs of high-quality and high-decorative painting. There is an existing spraying production line. This spraying production line includes a spray booth with a ventilation pipe at the top. A plurality of spray booths are arranged in the spray booth. The water curtain cabinet connected to the ventilation pipe, the water curtain cab...

AI Technical Summary

Problems solved by technology

[0003] 1. When spraying paint, the water in the overflow tank on the top of the water curtain plate overflows and flows down along the water curtain plate, forming a water film on the water curtain plate, and the paint mist in the air collides with the water film and dissolves into the water film; The water curtain plate of the water curtain cabinet on one side has only one curved surface, the contact area between the water film and the paint mist is small, the adsorption and capture amount of the paint mist is small, the processing speed of the paint mist is slow, and the air in the spray booth higher paint mist content;

[0004] 2. The surface of the water curtain plate is a curved surface. When spraying, the airflow containing paint mist rushes to the curved surface of the water curtain plate. The paint mist rebounds after colliding with the water curtain plate, which will pollute the air again and endanger the operator. health
