Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 and Figure 4 The present invention provides an embodiment of a dispensing needle with an adhesive smoothing mechanism, comprising a U-shaped head 1, wherein an adhesive roller 15 is provided at the lower end of the U-shaped head 1, and the adhesive roller 15 is symmetrically distributed at the left and right ends of the U-shaped head 1.

[0024] Specifically, during the dispensing process using the dispensing needle, the glue is applied to the surface, and at the same time, the glue roller 15 below the U-shaped head 1 rolls the applied glue to smooth the glue on the surface, so that the glue can be evenly applied to the surface.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The mounting cylinder 3 has its side end fixedly connected to the inner side wall of the U-shaped head 1 via a fixing rod 4. The upper end of the mounting cylinder 3 abuts against the upper inner wall of the U-shaped head 1. The mounting cylinder 3 is internally threaded with a glue cylinder 2. The side end of the glue cylinder 2 is fixedly connected with a limit ring 5. The limit ring 5 abuts against the lower end of the mounting cylinder 3. The lower end of the glue cylinder 2 is threadedly connected with a sealing cylinder cover 14. The sealing cylinder cover 14 is provided with a threaded mounting tube 9. The side end of the glue cylinder 2 is sleeved with a sealing ring 6. The sealing ring 6 is located between the limit ring 5 and the sealing cylinder cover 14. The sealing ring 6 abuts against the lower end of the limit ring 5 and the upper end of the sealing cylinder cover 14.

[0026] Specifically, during the disassembly and assembly of the dispensing needle, the glue cylinder 2 is installed inside the mounting cylinder 3 by means of threaded installation. The glue cylinder 2 can be unscrewed from the mounting cylinder 3 for disassembly, and the glue cylinder 2 can be screwed into the mounting cylinder 3 for installation. The sealing cylinder cover 14 is installed at the lower end of the glue cylinder 2 by means of threaded installation. The sealing cylinder cover 14 can be unscrewed from the glue cylinder 2 for disassembly, and the sealing cylinder cover 14 can be screwed tightly and fixed on the glue cylinder 2 for installation.

[0027] Reference Figure 1 and Figure 2 A threaded column 11 is threadedly connected to a threaded mounting tube 9. A channel 10 is provided inside the threaded column 11. A limiting ring 8 is fixedly connected to the inner side wall of the threaded mounting tube 9. The limiting ring 8 is located above the threaded column 11. A needle tube 12 is fixedly connected to the lower end of the threaded column 11. A ball bearing 13 is provided at the lower end of the needle tube 12. The lower end of the ball bearing 13 is flush with the lower end of the glue coating roller 15. The needle tube 12 is connected to the channel 10. A glue suction tube 7 is fixedly connected to the upper end of the threaded column 11. The glue suction tube 7 extends into the glue tank 2. The glue suction tube 7 is connected to the channel 10. The limiting ring 8 abuts against the upper end of the threaded column 11. The limiting ring 8 is sleeved with the glue suction tube 7. The ball bearing 13 is located at the center of the lower end of the glue suction tube 7. The ball bearing 13, the channel 10, and the glue suction tube 7 are located on the same axis.

[0028] Specifically, during the dispensing process of the dispensing needle, the glue tank 2 stores glue for dispensing, and the threaded mounting tube 9 is equipped with a threaded post 11. The glue in the glue tank 2 enters the channel 10 of the threaded post 11 through the glue suction tube 7, and then enters the needle tube 12 through the channel 10 of the threaded post 11. At this time, the glue flows to the position of the ball bearing 13 at the lower end of the needle tube 12. When the ball bearing 13 rolls, it carries the glue out. The glue is spread on the surface by the rolling of the ball bearing 13, and the glue can be smoothed by the glue application roller 15.

[0029] Working principle: The dispensing needle with a glue smoothing mechanism is used for dispensing. During use, the dispensing needle is pointed downwards, and the glue in the glue tank 2 will seep out from the inside through the suction tube 7, the channel 10, the needle tube 12 and the ball bearing 13. The rolling of the ball bearing 13 can apply the glue to the surface. The glue roller 15 at the lower end of the U-shaped head 1 will roll and press the glue applied to the surface, so that the glue can be evenly applied to the surface, thereby completing the dispensing and glue smoothing process.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
