Description

Technical Field

[0001] This utility model relates to the field of nail tip spraying technology, and in particular to a desktop spraying machine for wearable nail tip spraying. Background Technology

[0002] Wearable nail tips are primarily used to decorate nails, enhancing their appearance and adding dimension. To improve the aesthetics of these decorations, they are typically sprayed with various finishes, such as base coats, gradient colors, or blush. Currently, surface spraying of wearable nail tips mainly relies on manual operation. Workers must use handheld nail spray guns or brushes to spray each tip individually. Existing methods for spraying wearable nail tips have the following drawbacks:

[0003] 1) When using a nail spray gun to spray base color, blush or gradient, manual operation is easy to cause improper control, resulting in overlapping or omission of the nail tip coating, or uneven thickness on both sides of the sprayed nail tip, poor coating uniformity, and difficulty in controlling the uniformity of spraying.

[0004] 2) Poor consistency due to manual spraying: Different workers have different operating techniques, and the same batch of nail tips may have problems such as color difference, uneven coating thickness, and pattern deviation.

[0005] 3) Manual spraying is used, which is slow and has low production efficiency, and cannot meet the needs of large-scale wearable nail plate spraying.

[0006] 4) The required labor costs are high, as spraying technology is highly dependent on skilled workers, and the cost of training these workers is high. Utility Model Content

One end of the X-axis slide block 112 is fixed to the X-axis slider 113, and the other end of the X-axis slide block 112 is fixed to the other side of the Z-axis linkage fixing plate 14. The X-axis drive assembly 114 is connected to the X-axis slider 113 for driving the X-axis slider 113 to slide along the X-axis slide rail 111. This causes the Z-axis linkage fixing plate 14 on the X-axis slide 112 and its Z-axis lifting mechanism 13 to move along the X-axis direction. The X-axis drive assembly 114 includes two sets of X-axis drive motors 1141, an X-axis synchronous belt 1142, two sets of X-axis synchronous pulleys 1143, and X-axis synchronous belt clamps 1144.

In specific implementation, two sets of X-axis synchronous pulleys 1143 are also set on both sides of the X-axis slide rail 111 and the X-axis slider 113. The X-axis drive motor 1141 drives the X-axis synchronous pulleys 1143 to rotate. The X-axis synchronous pulleys 1143 start to move under the transmission action of the two sets of X-axis synchronous pulleys 1143, and circulate along the path between the two sets of X-axis synchronous pulleys 1143. This causes the X-axis synchronous belt clips 1144 on the X-axis synchronous belt 1142 to move accordingly, which in turn causes the X-axis slider 113 and the X-axis slide block 112 on the X-axis slider 113 to move along the X-axis slide rail 111. During the movement, the X-axis slide block 112 will drive the Z-axis linkage fixing plate 14 and its Z-axis lifting mechanism 13 and spraying structure 3 to move along the X-axis direction.

The Z-axis drive assembly 135 is connected to the Z-axis slider 134 for driving the Z-axis slider 134 to slide along the Z-axis slide rail 132. This causes the Z-axis moving fixing plate 136 on the Z-axis slide 133 and the spraying structure 3 on it to move along the Z-axis direction. The Z-axis drive assembly 135 includes two sets of Z-axis drive motors 1351, a Z-axis synchronous belt 1352, two sets of Z-axis synchronous pulleys 1353, and a Z-axis synchronous belt clamp 1354.

In specific implementation, two sets of Z-axis synchronous pulleys 1353 are also set on both sides of the Z-axis slide rail 132 and the Z-axis slider 134. The Z-axis drive motor 1351 drives the Z-axis synchronous pulleys 1353 to rotate. Under the transmission action of the two sets of Z-axis synchronous pulleys 1353, the Z-axis synchronous pulleys 1353 start to move and circulate along the path between the two sets of Z-axis synchronous pulleys 1353. This causes the Z-axis synchronous belt clips 1354 on the Z-axis synchronous belt 1352 to move accordingly, and then causes the Z-axis slider 134 and its Z-axis moving fixing plate 136 and spraying structure 3 to move together along the Z-axis slide rail 132.

[0070] Compared with the prior art, the technical solution disclosed in the above embodiments has the following beneficial effects:

[0071] In the above embodiments, the desktop spraying machine of this utility model places the wearable armor plate 6 to be sprayed through the spraying fixture structure 2, and uses the spraying structure 3 above the spraying fixture structure 2 to spray the wearable armor plate 6. The Y-axis moving mechanism 12 drives the spraying fixture structure 2 and the wearable armor plate 6 on the spraying fixture structure 2 to reciprocate in the Y-axis direction, so as to facilitate the automatic spraying of the wearable armor plate 6 by the spraying structure 3 above the Y-axis moving mechanism 12. The X-axis moving mechanism 11 drives the Z-axis linkage fixing plate 14 and the Z-axis lifting mechanism 13 on the Z-axis linkage fixing plate 14 and the spraying structure 3 as a whole to move in the X-axis direction, so that the spraying structure 3 moves along the X-axis direction. The wearable armor plates 6 on the spraying fixture structure 2 are reciprocated for spraying. The Z-axis lifting mechanism 13 drives the spraying structure 3 to move up and down. The X-axis moving mechanism 11, Y-axis moving mechanism 12, and Z-axis lifting mechanism 13 of the three-axis desktop machine 1 cooperate with the spraying structure 3 to realize the automatic spraying of the wearable armor plates 6, improve the spraying efficiency, and are suitable for mass production. It can meet the user's requirements for batch spraying of wearable armor plates 6, and solve the technical problems of low efficiency, uneven spraying, poor spraying quality and inability to meet the needs of mass production of traditional manual wearable armor plate 6 spraying operation. It also reduces the skill requirements of operators and reduces labor costs.

[0072] The above-disclosed embodiments are merely several preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
