[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-Figure 5 , the figure shows a nozzle structure of a tire glue spraying machine, specifically a nozzle of a glue spraying machine for spraying glue on the inner wall of a tire. It is worth noting that in this embodiment: the nozzle structure includes a rotatable nozzle 1 and a driving mechanism 2 for driving the nozzle 1 to rotate, the nozzle 1 is connected to the glue storage part through a pipe 3, and the driving mechanism 2 drives the nozzle to rotate in coordination with the rotation of the tire so that the glue sprayed by the nozzle 1 forms a spiral glue line on the inner wall of the tire. The spiral glue lines formed by the glue on the inner wall of the tire can be precisely controlled by controlling the rotation speed of the nozzle and the rotation speed of the tire, and the spacing between the glue lines can be ensured to be equal, so as to achieve the purpose of uniform glue spraying.

[0020] In order to improve the glue spraying efficiency, the present embodiment designs two nozzles 1, and the driving mechanism 2 drives the two nozzles 1 to rotate in opposite directions. The two nozzles 1 rotate in opposite directions so that both sides of the tire are sprayed inwards. One nozzle only needs to spray half of the tire, thereby improving efficiency.

[0021] In order to realize the synchronous movement of the two nozzles, so that the two nozzles can complete the spraying work of half a tire at the same time, the present embodiment connects the two nozzles 1 to the two ends of a connector 4 respectively. The connector 4 has a glue inlet 41 and two glue outlets 42. The glue inlet 41 is connected to the pipeline 3, and the glue outlet 42 is connected to the nozzle 1. The connector 4 is provided with an axially arranged flow channel. The glue inlet 41 is arranged in the middle position of the connector 4 and is connected to the flow channel. The side walls at both ends of the connector 4 are provided with notches that expose the flow channel in the connector 4. The nozzle 1 is connected at this position and is connected to the notch. The nozzle 1 includes a glue outlet head 11 and a glue outlet connecting plate 12. The glue outlet head 11 is fixed on the glue outlet connecting plate 12. The glue outlet connecting plate 12 is movably sleeved on the connector 4. The glue outlet connecting plate is driven to rotate on the connector by a driving mechanism to change the orientation angle of the glue outlet head. The driving mechanism 2 includes a motor 21, a bidirectional screw 22 connected to the output end of the motor, a guide rail 23, and a slider 24 slidably connected to the guide rail 23. The glue outlet connecting plate 12 of the nozzle 1 is provided with a long groove 121. The two glue outlet connecting plates 12 are respectively connected to the corresponding sliders 24 through the long grooves 121 on the glue outlet connecting plate 12 through the connecting pieces 25. The bidirectional screw 22 is provided with two sections of external threads in opposite directions. There are two sliders 24, which are respectively arranged on the two sections of threads of the bidirectional screw 22, and the sliders 24 are provided with threaded holes that match the threads of the bidirectional screw 22. The two sliders 24 are driven to move toward each other or back to back through the rotation of the bidirectional screw 22. The two sliders 24 are driven to move simultaneously by the bidirectional screw 22, thereby driving the two glue outlet connecting plates 12 to rotate in the opposite direction, so as to realize the synchronous operation of the two nozzles 1. The setting of the bidirectional screw 22 can accurately control the movement speed of the slider 24, thereby accurately controlling the rotation speed of the glue outlet connecting plate 12. In order to facilitate the processing of the flow channel of the connector 4 in this embodiment, the connector 4 is provided with an axially through-hole in this embodiment, and is connected to plugs 5 at both ends. The diameters of the two ends of the connector 4 are slightly smaller and form a step structure with the middle position. The glue outlet connecting plate 12 is sleeved on the part of the connector 4 with a slightly smaller diameter, and is locked on the connector 4 by the plug 5 to prevent the glue outlet connecting plate 12 from slipping out of the connector 4. In this embodiment, the glue outlet head 11 is threadedly connected to the glue outlet connecting plate 12, and the glue outlet connecting plate 12 is provided with a threaded through hole corresponding to the position of the notch. The glue outlet head 11 is connected to the threaded through hole of the glue outlet connecting plate 12 and is connected to the notch. The glue outlet head 11 has a flow channel with a hollow structure. When the glue outlet head 11 rotates within a certain range with the glue outlet connecting plate 12, it can ensure that the flow channel in the glue outlet head 11 is in a connected state with the notch within the range, so that the glue outlet amount of the nozzle 1 remains unchanged when the nozzle 1 rotates.
