When the lead screw 21 moves backward, the piston 22 will hit the lower limit switch 22a of the piston installed on the base plate 11 at the bottom. It is used to notify the control system to stop the driving of the second motor 31; at the same time, when the lead screw 21 moves forward, if the piston 22 pushes the glue tank 400 to the end, it will collide with the piston upper limit switch 22b through the upper limit collision ring 22c, which also The controller will be notified to stop the driving of the second motor 31 . Through the above control, the movement of the lead screw 21 is automatically controlled.

In addition, the ring body 12b1 has an inclined surface 12b4 inclined toward the center of the ring body 12b1, so that when a pull rod 12a is put into the corresponding gap 12b2, when the glue tank 400 is pushed, the inclined surface 12b4 can close the pull rod 12a, preventing the The pull rod 12a is disengaged outward.

In addition, as can be seen from the above, the installation of the glue tank 400 is carried out as follows: slightly pull out the pull rod 12a, put the glue tank 400 in from the front end, make its base rest on the piston 22, and then put the restraint ring 12b on the glue tank On the tapered end cap above 400, put the four tie rods 12a into the four notches 12b2 of the confinement ring 12b respectively, so that the tie rod studs 12a3 are clamped above the confinement ring 12b, and pass through the inclined surface 12b4 above the confinement ring 12b. When extruding the glue tank 400, the inclined surface 12b4 can close the pull rod 12a to prevent the pull rod 12a from escaping outward, and then through the magnets 12b3 on both sides of the gap 12b2 of the restraint ring 12b, the pull rod 12a can be prevented from coming off to a certain extent.
