[0022] A groove is provided in the second slider 4, and a driving motor 21 is installed in the groove, a threaded barrel 11 is installed at the top of the temporary storage chamber 13, and a screw 10 is connected to the threaded barrel 11, and a connecting rod 12 is installed at one end of the screw 10 in the temporary storage chamber 13, and two annular grooves are provided on the annular surface of the connecting rod 12, and a blocking plate 17 is rotatably connected in the annular groove, and the blocking plate 17 is in sliding contact with the rubber inlet pipe 6, and the end of the connecting rod 12 away from the screw 10 passes through the rotating plate 22 and extends to the outside of the temporary storage chamber 13, and a rectangular block 9 is installed at the end of the connecting rod 12 away from the screw 10 and the end of the screw 10 away from the connecting rod 12, and the outer surface of the rectangular block 9 is sleeved with a rotating barrel 8 with a rectangular groove provided inside, and the rotating barrel 8 arranged at the top of the temporary storage chamber 13 is connected to the output end of the driving motor 21, and the rotating barrel 8 arranged at the bottom of the temporary storage chamber 13 is connected to the rotating plate 22.

[0023] By installing a blocking structure consisting of a threaded cylinder 11, a screw 10, a connecting rod 12, a rotating cylinder 8 and a blocking plate 17 in the temporary storage chamber 13, the blocking structure is used to intercept the glue inlet pipe 6, thereby controlling the amount of glue entering the temporary storage chamber 13 at the curved path, thereby avoiding uneven glue spraying on the curved path.

[0024] A cylinder 5 is installed on the side of the second sliding block 4 away from the second sliding rail 7, and a support plate 16 is installed in the cylinder 5. The end of the rotating cylinder 8 arranged at the bottom of the temporary storage chamber 13 away from the rotating plate 22 is rotatably connected to the support plate 16, and then a plurality of first hinged plates 18 and second hinged plates 19 are arranged between the rotating cylinder 8 and the cylinder 5. The first hinged plate 18 and the second hinged plate 19 are hinged and arranged below the glue spraying nozzle 14. One end of the first hinged plate 18 is rotatably connected to the inner surface of the cylinder 5, and the end of the first hinged plate 18 away from the cylinder 5 is in sliding contact with the rotating cylinder 8, and one end of the second hinged plate 19 is rotatably connected to the rotating cylinder 8, and the end of the second hinged plate 19 away from the rotating cylinder 8 is in sliding contact with the cylinder 5.

[0025] An adjusting structure consisting of a first hinge plate 18 and a second hinge plate 19 is installed between the rotating cylinder 8 and the cylinder 5. The rotating cylinder 8 is driven by the adjusting structure to block the glue nozzle 14 close to the curved path side, so that the glue output of the glue nozzle 14 close to the curved path side is reduced, and the glue output of the glue nozzle 14 away from the curved path side is increased, thereby reducing the difference in glue amount on both sides of the curved path.

[0026] The hinge position of the first hinge plate 18 and the cylinder 5 is set to be higher than the hinge position of the second hinge plate 19 and the rotating cylinder 8. A collecting groove 20 is opened on the side of the first hinge plate 18 and the second hinge plate 19 that are opposite to each other and close to the rotating cylinder 8. The collecting groove 20 is used to collect the glue sprayed on the first hinge plate 18 and the second hinge plate 19. Then, a collecting cover 15 is installed on the annular surface of the rotating cylinder 8. The collecting cover 15 is located directly below the collecting groove 20. The collecting cover 15 is used to collect the glue collected in the collecting groove 20 to prevent the glue from dripping and contaminating the parts. In order to facilitate the glue to fall into the collecting cover 15, the hinge position of the first hinge plate 18 and the cylinder 5 is set to be higher than the hinge position of the second hinge plate 19 and the rotating cylinder 8.

[0027] The specific operation process of the present invention is as follows: glue enters the temporary storage chamber 13 through the glue inlet pipe 6, and is then discharged through the glue spray nozzle 14. When the glue spraying path needs to turn, the output end of the driving motor 21 is rotated clockwise or counterclockwise to drive the rectangular block 9 to rotate clockwise or counterclockwise. The rectangular block 9 rotates clockwise or counterclockwise to drive the screw 10 to rotate and move up and down in the threaded sleeve, so that the two blocking plates 17 installed on the annular surface of the connecting rod 12 intercept the glue inlet pipe 6, so that the amount of glue discharged from the glue inlet pipe 6 into the temporary storage chamber 13 is reduced, so as to avoid excessive pressure in the temporary storage chamber 13, which causes the glue spray nozzle 14 to discharge glue faster and unable to discharge glue evenly.

[0028] When the connecting rod 12 rotates, the rotating cylinder 8 is driven to rotate through the rectangular block 9, and the rotation of the rotating cylinder 8 drives the rotating plate 22 to rotate, so that the glue discharge path of the glue nozzle 14 becomes an arc. At the same time, the rotation of the rotating cylinder 8 drives the second hinged plate 19 to rotate, so that the angle between the first intersection plate and the second intersection plate on the side close to the curved path is enlarged and more glue is intercepted, and the angle between the first intersection plate and the second intersection plate on the side away from the curved path is reduced to intercept less glue, thereby reducing the difference in the amount of glue on both sides of the curved path.

[0029] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
