Automatic spraying device

Abstract

The invention belongs to the technical field of paint spraying equipment and particularly relates to an automatic spraying device. The automatic spraying device comprises a storage tank, mounting plate supporting legs, a mounting plate, an electromagnetic device, a permanent magnet, a handle, a rod A, a rod B, a hinge, a rod C, a fastening nut, a nozzle sleeve, a nozzle, a paint spraying tank, a paint spraying pipe, a controllable valve, a control device and a production line; the storage tank is fixed on the mounting plate supporting leg on the left side and is connected with the paint spraying tank through the paint spraying pipe; the paint spraying pipe is provided with the controllable valve; the paint spraying tank is fixed on the mounting plate; the nozzle is arranged at the lower end of the paint spraying tank; the electromagnetic device is fixed on the mounting plate supporting leg on the left side; and the permanent magnet is fixed at the tail end of the handle. The automatic spraying device is simple in structure and high in pertinence, the circulation condition of paint can be controlled, sealing or opening of the nozzle is realized with the mechanism self-locking principle, and the device has the broad application prospect and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of painting equipment, in particular to an automatic painting device. Background technique [0002] The traditional spraying machine uses compressed air to atomize the paint, and the spray speed of the paint is generally 10 m / s. Such a fast spray speed leads to excessive spraying of the paint and serious rebound phenomenon, and brings back a large number of paint molecules causing The paint is scattered and flying, which not only wastes a lot of paint, but also causes serious pollution to the air, and at the same time, the surface of the paint is prone to flaws. Due to the strong recoil force during spraying, the paint is not easy to adhere to the corners and edges of the workpiece, so it takes more time to spray, causing the nearby surface to sag. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an automatic spraying device...
