[0002] Clocks are a common timing tool in our lives. There are many small parts inside the clock, such as springs. The springs inside the clock can provide power to keep the clock running. The springs will be tightened and then release the stored energy to drive the mechanical device inside the clock to operate, so that the pointer or digital display will move continuously to show the time. In order to achieve better rust prevention during the production process, clock springs often need to be sprayed with paint on their surface.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-Figure 5 In order to solve the problem of uneven spraying caused by the inability of traditional devices to rotate during spraying, this embodiment provides the following technical solutions: a rotating mechanism is set, and the rotating mechanism is used to drive the spring to rotate axially during the spraying process, so that the spraying is more uniform. Specifically disclosed: an outer box body 1 is placed on the ground, and a protective door 2 is installed on the front side of the outer box body 1 by hinge rotation. A horizontally arranged mounting plate 3 is fixedly installed at the lower end of the inner part of the outer box body 1, and a supporting turntable 4 is rotatably installed in the middle position above the mounting plate 3, and the supporting turntable 4 is driven to rotate by a driving motor 5 fixedly installed at the bottom end of the inner part of the outer box body 1. Paint spray heads 6 with an arc-shaped structure are fixedly installed on the left and right sides of the surface, and the paint spray heads 6 form a communication structure with the paint box 8 fixedly installed on the outside of the upper end of the outer box body 1 through the delivery pipe 7. A rotating mechanism for driving the clock spring to rotate is provided above the carrying turntable 4. The rotating mechanism includes lower hooks 9 rotatably installed above the carrying turntable 4 at equal intervals. The lower end of the lower hook 9 is coaxially fixed with a driving roller 10 for driving it to rotate, and the driving roller 10 and the fixing ring 14 fixedly installed on the upper surface of the mounting plate 3 are in contact and friction with each other, and the driving roller 10 and the fixing ring 14 are both set to a rubber material with a rough surface.

[0033] When using the device, first open the protective door 2 and place the clock spring that needs to be painted into the outer box body 1, and use the cooperation between the upper hook 13 and the lower hook 9 to hang and fix it. Then close the protective door 2 and turn on the drive motor 5. Use the drive motor 5 to drive the carrying turntable 4 to rotate. During the rotation of the carrying turntable 4, the spring between the lower hook 9 and the upper hook 13 is driven to move synchronously. At this time, the active roller 10 at the lower end of the lower hook 9 and the fixed ring 14 rub against each other. Under the action of friction, the active roller 10 drives the lower hook 9 to rotate, thereby rotating the spring. At the same time, the paint nozzle 6 sprays the paint in the paint box 8 through the delivery pipe 7 under the action of the pump body, thereby achieving the purpose of spraying the surface of the spring.

[0034] Example 2: Please refer to Figure 2 and Figure 3 In order to achieve a better spraying effect, this embodiment provides the following technical solutions, which specifically disclose: a longitudinally arranged telescopic cylinder 11 is fixedly installed in the middle position of the upper surface of the supporting turntable 4, and a support frame 12 is fixedly installed on the top of the telescopic cylinder 11, and an upper hook 13 is rotatably installed at the lower front end of the support frame 12, and the positions of the upper hook 13 and the lower hook 9 correspond to each other, and the upper hook 13 and the lower hook 9 cooperate to hang and fix the clock spring that needs to be painted.

[0035] During the spraying process, the telescopic cylinder 11 is opened regularly, and the telescopic cylinder 11 is used to push the support frame 12 upward, thereby changing the distance between the upper hook 13 and the lower hook 9, pulling the spring, and increasing the internal distance of the spring itself, so that the sprayed paint can reach the internal gap.

[0036] Example 3: Please refer to Figure 6 and Figure 7 In order to solve the problem that the traditional device cannot quickly dry the paint during the spraying process, this embodiment provides the following technical solutions: a drying mechanism is set up, and the hot air generated in the drying mechanism is used to dry the paint during the spraying process. Specifically, the embodiment discloses: a drying mechanism for drying the sprayed paint is installed at the bottom end of the outer box body 1, and the drying mechanism includes two blower boxes 15 fixedly installed at the lower end of the inner part of the outer box body 1, and a push rod 16 is slidably installed through the side of the blower box 15. The push rod 16 and the extrusion cam 17 fixedly installed on the output shaft of the drive motor 5 correspond to each other on the left and right, and a piston plate 18 located inside the blower box 15 is fixedly installed at the bottom end of the push rod 16, and a return spring 19 for pushing it to return is installed on the outside of the push rod 16. A heating resistor 20 is fixedly installed inside the blower box 15, and the blower box 15 forms a communication structure with a drying nozzle 22 through a connecting hose 21 installed through the side, and the drying nozzle 22 is fixedly installed on the side of the paint nozzle 6.

[0037] When the driving motor 5 is turned on, it drives the extrusion cam 17 to rotate synchronously, and uses the extrusion cam 17 to squeeze the push rod 16. At this time, the push rod 16 pushes the piston plate 18 to move inside the blower box 15, and then cooperates with the elastic action of the return spring 19 to make the piston plate 18 move back and forth to achieve the purpose of blowing. The blown air is first heated by the heating resistance wire 20, and then sprayed out from the drying nozzle 22 through the connecting hose 21, so as to achieve the purpose of quickly drying the sprayed paint.
