[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A spraying device for the shell of an alarm clock during production includes a counterweight base. At the center of the upper end of the counterweight base, a column is fixed. Inside the top of the column, a motor is fixedly installed. The output end of the motor is fixedly connected with a conical tooth. A turntable is sleeved on the outer side of the middle part of the column through a bearing. Above the center of the turntable, a conical tooth ring is fixed. The conical tooth ring meshes with the conical tooth. Along the circumferential direction, a plurality of bearing components for placing alarm clocks are installed on the outer edge of the turntable. A housing is fixedly sleeved on the outer side of the top of the column. The bottom end of the housing is in sliding fit with the turntable, and a cavity is formed between the two.

The top of the vertical shaft 71 is fixedly connected with a support plate 73. The middle inner side of the support plate 73 is connected to a bidirectional lead screw 74 through a bearing. Two chutes 75 are symmetrically opened inside the support plate 73. Two slide bars 76 are respectively slidably arranged inside the two chutes 75. The bottom ends of the two slide bars 76 are respectively threadedly sleeved on the outer sides of both ends of the bidirectional lead screw 74.

[0030] As a preferred embodiment, on the basis of the above structure, preferably, the small gear 72 is meshed with the large gear 10, and the sliding directions of the two slide bars 76 are always opposite.

[0031] In this embodiment, when the turntable 6 drives the plurality of bearing components 7 to rotate around the column 2, by using the meshed small gear 72 and large gear 10, the bearing component 7 can drive the alarm clock outer shell fixed above it to rotate, which is convenient for full-round spraying of the alarm clock outer shell.

[0032] As a preferred embodiment, on the basis of the above structure, preferably, the paint spraying assembly 9 includes a spraying pipe 91, a spraying head 92, a connecting pipe 93, a shunt pipe 94, a material pump 95 and an infusion pipe 96. A plurality of spraying pipes 91 are all arranged in the spraying cavity and are equally angularly distributed around the column 2 as the center. A plurality of spraying heads 92 are equidistantly arranged on the inner wall of the spraying pipe 91. The middle parts of the ends of the plurality of spraying pipes 91 away from the column 2 are respectively fixedly communicated with a plurality of connecting pipes 93.

[0035] On the basis of the above structure, as an embodiment, the material pump 95 is fixedly installed on the rear outer wall of the counterweight base 1; as another embodiment, the material pump 95 is fixedly installed on the top of the column 2 and is located outside the outer housing 8.

[0036] The working principle of the present utility model is as follows:

[0037] When in use, first start the motor 3, control the conical gear 4 to rotate, and drive the turntable 6 and a plurality of bearing assemblies 7 to slowly rotate around the column 2 through the bevel gear ring 5. At this time, the outer shells of the alarm clocks to be sprayed can be sequentially placed above a plurality of support plates 73, and the outer shells of the alarm clocks are sleeved outside the two slide rods 76. Then manually rotate the bidirectional lead screw 74 to control the two slide rods 76 to move synchronously in the chute 75 in the direction away from each other, so as to clamp and position the outer shells of the alarm clocks from the inside, avoiding affecting the painting of the outer surface of the outer shells of the alarm clocks.

Moreover, by using the meshing large gear 10 and small gear 72, the bearing assembly 7 can be rotated around the column 2 while driving the outer shell of the alarm clock to rotate itself, facilitating the full and dead-angle-free spraying of the outer shell of the alarm clock;

[0038] After the spraying of the alarm clock housing is completed, it can continue to enter the drying chamber on the right side of the outer housing 8 following the turntable 6. By turning on the hot air blower 11, hot air can enter the drying chamber and blow towards the alarm clock housing, enabling rapid drying of the sprayed alarm clock housing. Subsequently, the alarm clock housing transferred out of the drying chamber can be removed. Similarly, a new alarm clock housing to be sprayed is installed, thereby enabling continuous spraying work;

[0039] Compared with the prior art, this device can significantly shorten the overall processing time of the alarm clock housing through continuous spraying, effectively improve work efficiency, is easy to operate, and has a faster processing speed, which has a significant promoting effect on the production capacity of alarm clocks.
