[0019] Two-color spraying device for thermos bottle surface, such as Figure 1 and Figure 2 As shown, it includes a spray outer box 1, which is square. A storage opening is opened on the top of the spray outer box 1, and a top cover 14 is arranged on the storage opening. A stepper motor 2 is installed at the bottom of the inner wall of the spray outer box 1, and a screw 3 is connected to the output end of the stepper motor 2. The outer side surface of the screw 3 is threadedly connected to a sliding plate 4, and the sliding plate 4 contacts the inner wall of the spray outer box 1. Two mounting bars 12 are fixed on the upper and lower outer sides of the screw 3, and contact switches 13 are installed on the mounting bars 12. The contact ends of the contact switches 13 face the sliding plate 4. The two contact switches 13 are electrically connected to the stepper motor 2. A stabilizing rod 17 is fixed to the bottom of the inner wall of the spray outer box 1, and the stabilizing rod 17 passes through the sliding plate 4 and is slidably connected to the sliding plate 4.

[0022] The working principle of the utility model is as follows:
[0023] Open the top cover 14 and place the thermos bottle to be sprayed through the protective sleeve 8 on the positioning sleeve seat 16 of the turntable 7. The initial state is as shown in the attached manual. Figure 1Schematic diagram of the structure of the lower spray gun 10 when it is started. The servo motor 5 is started to drive the central axis rod 6 and the turntable 7 to rotate, and then the thermos flask is driven to rotate. The lower spray gun 10 is started to spray the rotating thermos flask. Due to the presence of the protective sleeve 8, the upper half of the thermos flask in the protective sleeve 8 will not be sprayed. The stepper motor 2 is started to drive the screw 3 to rotate a certain number of circles, and then the sliding plate 4 is driven to move up a certain distance and then stop.
