DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme of the utility model to carry out clearly, complete description, and the advantage is more clear and distinct, the following combining with the figure to the utility model embodiment carries out further detailed explanation.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, instead of all the embodiments, only to explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the scope of the utility model protection.

[0027] Embodiment one, please refer to Figures 1-7 The utility model provides a kind of technical scheme: a kind of metering mechanism of three mouth glue injection equipment, three mouth glue injection machine main body 1 lower end is fixed with mounting plate 5, mounting plate 5 lower surface is fixed with threaded column 6, threaded column 6 inside is movably clamped with glue nozzle 4, threaded column 6 outer surface is movably clamped with threaded sleeve 2, threaded sleeve 2 and threaded column 6 clamping can be fixed glue nozzle 4 on glue injection machine main body 1.

[0028] Extrusion sleeve 3 is set with annular groove 18 in upper end inside, annular groove 18 is communicated with extrusion sleeve 3 upper end outer surface, spring 8 and retaining ring 9 are movably arranged in the inner wall of annular groove 18, due to the elasticity of spring 8, spring 8 reset will push retaining ring 9 to move upwards, make positioning tooth groove 11 re-clamp with positioning tooth block 15, make threaded sleeve 2 and extrusion sleeve 3 form limit.

[0029] On the basis of embodiment one, in order to realize the anti-loosening of glue nozzle 4, threaded column 6 is set with limit groove 7 in lower end outer surface, threaded sleeve 2 is set with threaded hole 12 inside, threaded sleeve 2 lower end is fixed with connecting block 13, connecting block 13 surface is fixed with annular block 14.

[0030] Annular groove 18 is set with connecting groove 17 in port, connecting groove 17 is communicated with annular groove 18 and extrusion sleeve 3 outside, annular block 14 is correspondingly clamped with annular groove 18, and the two are movably connected, on the one hand, threaded sleeve 2 and extrusion sleeve 3 are movably connected, on the other hand, threaded sleeve 2 and extrusion sleeve 3 are positioned, so that the two cannot be separated.

[0031] The lower surface of the annular block 14 is fixed with a positioning tooth block 15, the inner wall of the annular groove 18 is movably clamped with a spring 8 and a retaining ring 9, the upper surface of the retaining ring 9 is provided with a positioning tooth groove 11, and the spring 8 is located below the retaining ring 9. Due to the elasticity of the spring 8, the reset of the spring 8 will push the retaining ring 9 upwards, so that the positioning tooth groove 11 is re-clamped with the positioning tooth block 15.

[0032] The positioning tooth block 15 corresponds to and is clamped with the positioning tooth groove 11, and the two are movably connected. The positioning tooth groove 11 is clamped with the positioning tooth block 15, so that the threaded sleeve 2 and the extrusion sleeve 3 form a limit. The side surface of the retaining ring 9 is fixed with a pull block 10, and the side surface of the inner wall of the annular groove 18 is provided with a through groove 19. The through groove 19 communicates the annular groove 18 with the outside of the extrusion sleeve 3.

[0033] The pull block 10 corresponds to and is clamped with the through groove 19, and the two are movably connected. The depth of the through groove 19 is twice the thickness of the pull block 10. The depth of the positioning tooth groove 11 is the same as the thickness of the pull block 10. Therefore, the through groove 19 has enough space to separate the positioning tooth groove 11 and the positioning tooth block 15.

[0034] The inside of the extrusion sleeve 3 is fixed with a limiting block 16. The limiting block 16 corresponds to and is clamped with the limiting groove 7, and is movably connected. Since the extrusion sleeve 3 is limited from rotating by the mutual clamping of the limiting block 16 and the limiting groove 7, the threaded sleeve 2 cannot rotate on the threaded column 6, and the glue nozzle 4 will not loosen due to the running vibration of the three-nozzle glue injection machine body 1, thereby achieving the anti-loosening of the glue nozzle 4.

[0035] In actual use, when installing the glue nozzle 4, first clamp the glue nozzle 4 inside the threaded column 6, then sleeve the threaded sleeve 2 and the extrusion sleeve 3 outside the glue nozzle 4, then press the pull block 10 downwards to drive the positioning tooth groove 11 to move downwards in the annular groove 14 and extrude the spring 8. At this time, the positioning tooth groove 11 is separated from the positioning tooth block 15 and no longer clamped, and the limit between the threaded sleeve 2 and the extrusion sleeve 3 disappears. At this time, clamp the threaded sleeve 2 on the threaded column 6, and correspondingly position the limiting block 16 with the limiting groove 7. Rotating the threaded sleeve 2 on the threaded column 6 will drive the extrusion sleeve 3 to move upwards. When the threaded sleeve 2 is clamped at the top of the threaded column 6, the extrusion sleeve 3 will extrude and fix the glue nozzle 4 at the lower end. At this time, release the pull block 10. Due to the elasticity of the spring 8, the reset of the spring 8 will push the retaining ring 9 upwards, so that the positioning tooth groove 11 is re-clamped with the positioning tooth block 15, so that the threaded sleeve 2 and the extrusion sleeve 3 form a limit. Since the extrusion sleeve 3 is limited from rotating by the mutual clamping of the limiting block 16 and the limiting groove 7, the threaded sleeve 2 cannot rotate on the threaded column 6, and the glue nozzle 4 will not loosen due to the running vibration of the three-nozzle glue injection machine body 1, thereby achieving the anti-loosening of the glue nozzle 4.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
