[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0018] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting this application.

[0019] like Figures 1-2 As shown, a stopper rod inner hole coating device includes a conveyor 1, a placement table 2, a support plate 4, a support sleeve 5, a paint delivery pipe 6, a paint nozzle 7, a support column 8, and an electric heating wire 9. The placement table 2 is multiple and evenly arranged at the delivery end of the conveyor 1. The support plate 4 is connected to a driving component that drives it to move horizontally. The support sleeve 5 and the support column 8 are fixedly connected to the support plate 4. The support sleeve 5 is a hollow structure, and the paint delivery pipe 6 is arranged in the support sleeve 5. A plurality of paint nozzles 7 are arranged circumferentially on the end of the paint delivery pipe 6 facing the stopper rod, and electric heating wires 9 are arranged on four sides of the support column 8.

[0020] Specifically, the conveyor 1 circulates and transports the placement table 2 to continuously transport the stopper rod. The driving assembly drives the support sleeve 5 and the support column 8 to move horizontally away from the stopper rod or close to the stopper rod, so that the support sleeve 5 and the support column 8 can enter and exit the inner hole of the stopper rod. The circumferentially arranged paint nozzles 7 can cover the inner hole of the stopper rod with paint. The heating wires 9 on the four sides of the support column 8 emit heat to completely cover the inner hole and dry the paint in the inner hole.

[0021] Furthermore, the driving assembly includes a stand 10, a base 11, a slide rail 12, a slider 13, a motor 14, a gear 15, and a rack 16. The top of the stand 10 is detachably connected to the support plate 4, and the bottom of the stand 10 is fixedly connected to the base 11. The slider 13 is fixed to the bottom of the base 11, and the slider 13 slides in the slide rail 12. The rack 16 and the slide rail 12 are arranged side by side. The motor 14 is fixedly installed on the base 11, and the output shaft of the motor 14 is fixedly provided with a gear 15, and the gear 15 is engaged with the rack 16.

[0022] Specifically, the motor 14 is started to drive the gear 15 to rotate, the gear 15 engages with the rack 16, and then the base 11 is translated. At the same time, the slider 13 follows the base 11 to slide on the slide rail 12 to maintain a smooth displacement of the base 11, and then the stand 10 drives the support sleeve rod 5 and the support column 8 to translate, so that the support sleeve rod 5 and the support column 8 can enter and exit the inner hole of the stopper rod.

[0023] Furthermore, the placement table 2 is arranged horizontally, and a receiving groove 3 for placing the stopper rod is provided on the placement table 2. The support sleeve rod 5 and the support column 8 are parallel to the placement table 2 so that the driving assembly can drive the two in and out of the inner hole of the stopper rod.

[0024] Specifically, the stopper rod can be placed horizontally inside the receiving groove 3 and then transported by the conveyor 1. The supporting sleeve rod 5 and the supporting column 8 are parallel to the placement platform 2 so as to be transported in and out of the inner hole of the stopper rod.

[0025] Furthermore, the stand 10 is detachably connected to the support plate 4 by fasteners 17. A plurality of positioning holes 18 adapted to the fasteners 17 are evenly arranged on the stand 10 in the vertical direction. When it is necessary to adjust the height of the support sleeve 5 and the support column 8 to accommodate the plug rod, the fasteners 17 are screwed to remove the support plate 4, and then installed in the positioning holes 18 at different heights, so that the height of the support plate 4 can be adjusted, and then the height of the support sleeve 5 and the support column 8 can be adjusted.

[0026] Furthermore, the cross section of the support column 8 is rectangular so that the heating wires 9 can be installed on four sides along the length direction of the support column 8 .

[0027] In the above structure, the stopper rod to be coated with paint is placed inside the receiving groove 3, the motor 14 is started to drive the motor 14 to rotate, the motor 14 is engaged with the rack 16, and then the base 11 can be translated, so that the stand 10 and the support plate 4 are translated synchronously, and then the support sleeve 5 and the support column 8 are sent into the inner hole of the stopper rod, and then the paint is transported to the paint nozzle 7 through the paint delivery pipe 6, and then the paint is sprayed from the paint nozzle 7 to the inner hole wall of the stopper rod. At the same time, the paint evenly covers the inner hole wall during the movement. The conveyor 1 transports the placement table 2 to move the coated stopper rod to the front of the support column 8. At the same time, the support column 8 and the support sleeve 5 are synchronously inserted into the inner hole of the stopper rod, and the heating wire 9 is started to generate heat to dry the paint coated on the inner hole wall, so that continuous operation can be achieved to improve efficiency.
