Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-3 The fixing fixture of the glue cylinder of the glue dispensing machine shown in the figure includes a glue dispensing machine body 1, which is composed of a glue dispensing machine body 11, a clamping mechanism 12 and a glue cylinder 13. The clamping mechanism 12 is used to install the glue cylinder 13 on the glue dispensing machine. The clamping mechanism 12 is composed of an outer ring 121, a groove, a clamping block 122, a threaded hole, a threaded rod 123, a rotating block 124, an auxiliary component 125 and a rotation limit component 126. The bolt is composed of a rotating block 124 and a threaded rod 123. The outer ring 121 is sleeved on the outer wall of the glue cylinder 13, the groove is opened on the inner wall of the outer ring 121, and the threaded hole is opened on the outer ring 121. On the front side, the outer wall of the threaded rod 123 is threadedly connected to the inner wall of the threaded hole. The threaded rod 123 rotating clockwise in the threaded hole will drive the clamping block 122 gradually away from the threaded hole, and the threaded rod 123 rotating counterclockwise in the threaded hole will drive the clamping block 122 gradually close to the threaded hole. One end of the threaded rod 123 is rotatably connected to the front side of the clamping block 122, and the other end of the threaded rod 123 is fixedly connected to the back side of the rotating block 124. A protective pad 127 is fixedly connected to the back side of the clamping block 122. The protective pad 127 protects the rubber cylinder 13, and the back side of the protective pad 127 is provided with evenly distributed friction grooves.

[0025] The auxiliary component 125 includes an annular groove, which is opened on the outer wall of the rotating block 124. The inner cavity of the annular groove is provided with a rotating ring 1251. The outer wall of the rotating ring 1251 is provided with a circular hole. The inner cavity of the circular hole is provided with an assembly rod 1252. One end of the assembly rod 1252 is provided with an auxiliary rod 1253. In addition to facilitating the rotation of the rotating block 124, the auxiliary rod 1253 is also used to cooperate with the rotation-limiting component 126. One end of the assembly rod 1252 is fixedly connected to one end of the auxiliary rod 1253. The auxiliary rod 125 The outer wall of the annular groove 3 is provided with evenly distributed anti-slip grooves, which are used to increase the friction between the auxiliary rod 1253 and the palm of the staff. The inner wall of the annular groove is provided with a plurality of assembly holes in an annular array. The other end of the assembly rod 1252 is threadedly connected to the inner wall of the corresponding assembly hole. When the assembly rod 1252 is threadedly connected to the assembly hole, the rotating ring 1251 and the rotating block 124 rotate synchronously. When the assembly rod 1252 is separated from the assembly hole, the rotating ring 1251 and the rotating block 124 rotate asynchronously.

[0026] The rotation limiting assembly 126 includes a fixed block 1261, which is fixedly connected to one side of the outer ring 121. A rectangular through hole is provided on the front of the fixed block 1261. A movable plate 1262 is provided in the inner cavity of the rectangular through hole. An anti-slip hole is provided on one side of the movable plate 1262. The inner cavity of the anti-slip hole is provided with an anti-slip slider 1266.

A rotation limiting block 1263 is symmetrically provided at one end of the movable plate 1262. When the two rotation limiting blocks 1263 are respectively located directly above and directly below the auxiliary rod 1253, The auxiliary rod 1253, the rotating block 124 and the threaded rod 123 cannot rotate, and the two limiting blocks 1263 are symmetrically fixedly connected to the front of the movable plate 1262. The back of the movable plate 1262 is fixedly connected with a strip force plate 1264. The strip force plate 1264 is used to facilitate the staff to apply force to drive the movable plate 1262 and the limiting block 1263 to move. One side of the outer ring 121 is fixedly connected to a limiting rubber pad 1265. The limiting rubber pad 1265 limits the strip force plate 1264. When the strip force plate 1264 contacts the limiting rubber pad 1265, the strip force plate 1264 will not move in the absence of any external force.

[0027] Working principle of this utility model:

[0028] When assembling the rubber cylinder 13 on the dispensing machine, first insert the rubber cylinder 13 with the needle head downward into the outer ring 121. After determining the vertical height of the rubber cylinder 13, the auxiliary rod 1253 drives the rotating block 124 and the threaded rod 123 to rotate clockwise. The threaded rod 123 rotating clockwise in the threaded hole will drive the clamping block 122 and the protective pad 127 to gradually approach the rubber cylinder 13 and finally cooperate with the inner wall of the outer ring 121 to complete the clamping and installation of the rubber cylinder 13. Then rotate the auxiliary rod 1253 counterclockwise. When the assembly rod 1252 is completely aligned with the assembly hole, After disengagement, rotate the rotating ring 1251 until the auxiliary rod 1253 is in a horizontal state and close to the fixed block 1261, and then rotate the auxiliary rod 1253 clockwise. When the assembly rod 1252 is threadedly connected to the corresponding assembly hole, apply force to the strip force plate 1264, so that the strip force plate 1264 drives the two rotation limiting blocks 1263 to move to the top and bottom of the auxiliary rod 1253 respectively through the movable plate 1262. At this time, the rotation limiting step is completed, the loosening of the rubber cylinder 13 is avoided, and the stability of the installation of the rubber cylinder 13 is improved.
