Fig. 4 is a schematic operation of a powder coating apparatus for a metal workpiece.
Wherein: 1. the device comprises a main frame 2, a hanging plate 3, filter cloth 4, an air blowing pipe 5, an air spraying hole 6 and a coating pond.
Detailed Description
Fig. 1 to 4 are diagrams illustrating preferred embodiments of the present utility model, and the present utility model is further described below with reference to fig. 1 to 4.
As shown in fig. 1, a powder coating apparatus (hereinafter referred to as a coating apparatus) for a metal workpiece includes a main frame 1, the main frame 1 being a rectangular frame body, and a top portion of the main frame 1 being open. The periphery and the bottom of the main frame 1 are fixed by a plurality of side links which are mutually perpendicular, so that the coating device has an inner and outer transparent structure.
In combination with fig. 2-3, an air blowing pipe 4 is arranged at the bottom of the main frame 1, the air blowing pipe 4 is horizontally arranged in the main frame 1, one end of the air blowing pipe 4 is closed, the other end of the air blowing pipe is open, the closed end of the air blowing pipe 4 is positioned at one corner in the main frame 1, and meanwhile, the air blowing pipe 4 is arranged in a reciprocating manner on the inner wall of the main frame 1 and extends to the diagonal corner of the main frame 1. The open end of the air blowing pipe 4 extends from the edge of the main frame 1 to the outside of the main frame 1, and is bent vertically upwards to form an air inlet, and the air inlet of the air blowing pipe 4 is connected with an external air source through a pipeline. A plurality of air injection holes 5 are evenly arranged on the upper surface of the air blowing pipe 4. The air blowing pipe 4 may also be arranged at the same time at the inner surface of either end face inside the main frame 1, or/and at the middle of the main frame 1.
A filter cloth 3 is horizontally arranged below the main frame 1, and the filter cloth 3 is arranged above the air blowing pipe 4. The outer surface of the main frame 1 is also provided with a plurality of hanging plates 2, two layers of hanging plates 2 are arranged in the middle and the bottom of the outer surface of the main frame 1, and each layer is perpendicular to the main frame 1.
The specific working process and working principle are as follows:
