One side of the fixing plate 10 is provided with a baffle 27, the baffle 27 is fixedly sleeved on the outer side of the connecting rod 29, the baffle 27 is positioned on one side of the pulling plate 28 close to the fixing plate 10, and the pulling plate 28 is prevented from being tightly attached to the fixing plate 10 through the baffle 27.

A use method of a pneumatic glue gun with quantitative glue discharging function for a packaging rubber tube specifically comprises the following steps:

the method comprises the following steps: opening the glue gun head 9, filling liquid glue into the glue gun barrel 1, and then installing the glue gun head 9 on the glue gun barrel 1 to form a closed space;

step two: one hand holds the glue gun handle 2, the other hand holds the limiting rod 5, the limiting rod 5 is pulled towards the direction of the glue gun handle 2, the limiting rod 5 drives the adjusting block 19 to move in the adjusting groove 3, the adjusting block 19 extrudes the limiting block 25, the limiting block 25 moves into the limiting groove 26, so that the limiting spring 33 is compressed, when the adjusting block 19 is not contacted with the limiting block 25, the limiting block 25 moves towards the direction far away from the limiting groove 26 under the elastic force action of the limiting spring 33, so that the limiting block 25 is matched with the adjusting block 19 to form limiting, the limiting rod 5 drives the belt 4 to rotate while moving, as the driving belt pulley 8 and the driven belt pulley 11 are in transmission connection through the belt 4, the belt 4 drives the worm wheel 12 to rotate, the worm wheel 12 is matched with the worm wheel 13, so that the threaded rod 13 drives the threaded rod 14 to rotate, and the threaded rod 14 is in meshing connection with the pushing block, the pushing block 15 pushes the liquid glue to move towards the glue gun head 9 to extrude the glue gun barrel 1, the sliding block 24 is driven to slide while the adjusting block 19 moves, the sliding block 24 pulls the pull rope 23, the pull rope 23 drives the winding barrel 21 to rotate, and the winding barrel 21 compresses the flat spiral spring, so that the flat spiral spring has elasticity;

step three: after the liquid glue is used up, the pulling plate 28 is pulled towards the direction far away from the limiting plate 18, so that the pulling plate 28 drives the connecting rod 29 to move, the connecting rod 29 drives the limiting plate 18 to rotate by taking one end of the fixing column 20 as a circular point, the limiting between the limiting block 25 and the adjusting block 19 is released, the winding drum 21 starts to rotate under the elastic action of the flat spiral spring, so that the pull rope 23 drives the sliding block 24 to move towards the winding drum 21, so that the limiting rod 5 drives the belt 4 to move reversely, the belt 4 drives the worm 12 to rotate, the worm 12 is mutually matched with the worm wheel 13, the threaded rod 14 rotates, the driving pushing block 15 is driven to move towards the direction far away from the glue gun, and the static position is recovered.

The working principle is as follows: when the glue gun is used, firstly, the glue gun head 9 is opened, liquid glue is filled into the glue gun barrel 1, then the glue gun head 9 is installed on the glue gun barrel 1 to form a closed space, one hand holds the glue gun handle 2, the other hand holds the limiting rod 5, the limiting rod 5 is pulled towards the direction of the glue gun handle 2, so that the limiting rod 5 drives the adjusting block 19 to move in the adjusting groove 3, the adjusting block 19 extrudes the limiting block 25, the limiting block 25 moves into the limiting groove 26, so that the limiting spring 33 is compressed, when the adjusting block 19 is not in contact with the limiting block 25, the limiting block 25 moves towards the direction far away from the limiting groove 26 under the action of the elastic force of the limiting spring 33, so that the limiting block 25 is matched with the adjusting block 19 to form limiting, the limiting rod 5 drives the belt 4 to rotate while moving, and as the driving belt pulley 8 is in transmission connection with the driven belt pulley 11 through the belt 4, the belt 4 drives the worm 12 to rotate, the worm 12 and the worm wheel 13 are mutually matched, the worm wheel 13 drives the threaded rod 14 to rotate, the threaded rod 14 is meshed with the pushing block 15 through threads, the pushing block 15 pushes the liquid glue to move towards the glue gun head 9 to extrude the glue gun barrel 1, the adjusting block 19 moves and simultaneously drives the sliding block 24 to slide, the sliding block 24 pulls the pull rope 23, the pull rope 23 drives the winding barrel 21 to rotate, the winding barrel 21 compresses the flat spiral spring, the flat spiral spring has elasticity, after the liquid glue is used up, the pull plate 28 is pulled towards the direction far away from the limiting plate 18, the pull plate 28 drives the connecting rod 29 to move, the connecting rod 29 drives the limiting plate 18 to rotate by taking one end of the fixed column 20 as a round point, the limiting between the limiting block 25 and the adjusting block 19 is released, and the winding barrel 21 starts to rotate under the elastic force of the flat spiral, thereby make stay cord 23 drive slider 24 to the direction motion of coiling section of thick bamboo 21 to make gag lever post 5 drive belt 4 reverse motion, belt 4 drives worm 12 and rotates, and worm 12 and worm wheel 13 mutually support, make threaded rod 14 rotate, drive and promote piece 15 and move towards the direction of keeping away from the rifle of gluing, resume the position when static.
