Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and in particular relates to an anti-pollution forming air ring with a multi-stage air gathering structure. Background Art

[0002] The forming air ring is a spraying equipment device with a limited airflow direction. At present, most of the spraying workshops of enterprises use a robot equipped with an atomizer electrostatic spraying system. The high-pressure air drives the air motor to drive the rotary cup to rotate at high speed, so that the paint flows outward on the inner wall of the rotary cup. Under the combined action of the serrations on the edge of the rotary cup and the centrifugal force, it is atomized into smaller particles. The paint particles diverge outward from the edge of the rotary cup in a plane, and cannot be sprayed to the workpiece well, affecting the spraying quality. To solve this problem, the forming air ring is introduced, and its function is to use air to limit the movement direction of the paint particles, so as to better make the paint particles fly to the workpiece. The existing forming air ring is composed of 3 or 4 parts through threads or screws to form a channel for compressed air. However, as the atomizer rotates at high speed, the atomized paint particles may penetrate into the forming air ring, causing internal pollution of the forming air ring or even blocking the air outlet, thereby affecting the spraying quality; in addition, the outer wall of the rotary cup is also very easy to accumulate paint. When the paint accumulates to a certain extent, it will reduce the spraying quality of the workpiece to be sprayed, increase production costs, and affect work efficiency. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figures 2 to 5 As shown, a pollution-proof shaped air ring with a multi-stage air gathering structure comprises a fixed ring 1 and a shaped ring 2, wherein the fixed ring and the shaped ring are threadedly connected together.

[0019] like Figure 3 As shown, the top of the fixed ring 1 is provided with a first air inlet annular cavity 11, a second air inlet annular cavity 12 and a threaded mounting hole 13, and the threaded mounting holes 13 are four in an annular array. The bottom is provided with a plurality of air outlet holes 14. The lower part of the first annular cavity is connected with the air outlet holes on the outside through the first straight guide section 15, and the second air inlet annular cavity 12 is connected with the air outlet holes on the inside through the second straight guide section 16. The first air inlet annular cavity 11, the second air inlet annular cavity 12 and the air outlet holes 14 are in the same axial direction as the forming air ring. The first air inlet annular cavity 11 and the first straight guide section 15 connected in sequence constitute the first-stage air gathering structure. Similarly, the second air inlet annular cavity 12 and the second straight guide section 16 connected in sequence also constitute the first-stage air gathering structure. Function of the first-stage air gathering structure: When compressed air enters the first air inlet annular cavities 11 and 12 of the fixed ring 1, the function of the first-stage air gathering structure begins to work, and the air is guided to the forming ring 2 through the air outlet holes 14.

[0020] like Figure 5As shown, the top of the forming ring 2 is provided with a third air inlet annular cavity 21 and a fourth air inlet annular cavity 22, and the bottom of the forming ring 2 is provided with a first injection hole 23, a second injection hole 24, and a third injection hole 25 in the central area. The inside of the forming ring 2 is provided with a third straight guide section 26, a horizontal guide section 27, a second inclined guide section 28, a fourth straight guide section 29, and a first inclined guide section 30. The third air inlet annular cavity 21 and the fourth air inlet annular cavity 22 are respectively connected to the air outlet 14. The third air inlet annular cavity 21, the third straight guide section 26, and the first inclined guide section 30 connected in sequence together constitute a second-level air gathering structure. Similarly, the fourth air inlet annular cavity 22, the horizontal guide section 27, and the second inclined guide section 28 connected in sequence together constitute a second-level air gathering structure. Effect of the second-level air gathering structure: air then flows into the third air inlet annular cavity 21 and 22 of the forming ring 2, and the density of the airflow is further increased under the action of the third straight guide section 26, wherein the channels of the first and second inclined guide sections gradually narrow from wide to further strengthen air gathering. By such gathering, the airflow forms high-speed, directional spray at the first spray hole 23, the second spray hole 24 and the third spray hole 25, effectively shaping the paint mist and cleaning the outer wall of the rotary cup, thereby reducing pollution and optimizing the coating effect.

[0021] The anti-pollution forming air ring with a multi-stage air gathering structure is a shaping ring with three outlet channels formed by two air inlet channels, two of which are responsible for shaping the paint mist, and one outlet channel is responsible for blowing the outer wall of the rotary cup. The two air inlet channels are fixed together by a fixing ring and a shaping ring through a threaded connection. The anti-pollution forming air ring with a multi-stage air gathering structure is fixed on the atomizer through the top threaded hole.

[0022] Compared with the processing of complex structured molded air rings, the two-stage gathering air structure is easier to process, has lower requirements on processing equipment and low processing costs.

[0023] The fixing ring and the forming ring are connected by threads and adopt a two-stage air gathering structure to increase the air flow rate, so that the atomized paint mist is not easy to enter the atomizer and avoid the accumulation of the atomized paint mist, avoid the damage of the atomizer components, and improve the atomization quality and efficiency.

[0024] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
