[0022] One end of the unwinding shaft 2 is fixedly mounted on the first vertical plate 41, a first rotating disk 5 and a first baffle 6 located on the side of the first rotating disk 5 opposite to the first vertical plate 41 are mounted on the outer side of the unwinding shaft 2, the cloth roll 100 mounted on the unwinding shaft 2 is located between the first rotating disk 5 and the first baffle 6, a first nut 7 is mounted on the other end of the unwinding shaft 2, a spring 8 in an extruded state is mounted on the outer side of the unwinding shaft 2 and is located between the first nut 7 and the first baffle 6, a pad 9 is mounted on the side of the first vertical plate 41 facing the first rotating disk 5, the surface of the pad 9 opposite to the first vertical plate 41 is in frictional contact with the side surface of the first rotating disk 5 opposite to the cloth roll 100;

[0028] Embodiment 2: A cleaning mechanism for a dispensing nozzle, comprising: a base plate 1, an unwinding shaft 2 and a rewinding shaft 3, wherein one end of each of the unwinding shaft 2 and the rewinding shaft 3 is respectively mounted on the same side of a first vertical plate 41 and a second vertical plate 42, wherein the first vertical plate 41 and the second vertical plate 42 are both mounted on the upper surface of the base plate 1, and a cloth roll 100 is mounted on the unwinding shaft 2, wherein one end of the cloth roll 100 away from the unwinding shaft 2 is wound around the rewinding shaft 3, thereby forming a wiping cloth segment 103 between a new cloth roll segment 101 on the unwinding shaft 2 and a waste cloth roll segment 102 wound around the rewinding shaft 3;

[0029] One end of the unwinding shaft 2 is fixedly mounted on the first vertical plate 41, a first rotating disk 5 and a first baffle 6 located on the side of the first rotating disk 5 opposite to the first vertical plate 41 are mounted on the outer side of the unwinding shaft 2, the cloth roll 100 mounted on the unwinding shaft 2 is located between the first rotating disk 5 and the first baffle 6, a first nut 7 is mounted on the other end of the unwinding shaft 2, a spring 8 in an extruded state is mounted on the outer side of the unwinding shaft 2 and is located between the first nut 7 and the first baffle 6, a pad 9 is mounted on the side of the first vertical plate 41 facing the first rotating disk 5, the surface of the pad 9 opposite to the first vertical plate 41 is in frictional contact with the side surface of the first rotating disk 5 opposite to the cloth roll 100;

[0030] In the initial state, the spring continuously squeezes the cloth roll to prevent the cloth roll from rotating itself.

[0031] One end of the winding shaft 3 is fixedly mounted on the second vertical plate 42 , and a second rotating disk 10 and a second baffle 11 located on the side of the second rotating disk 10 opposite to the second vertical plate 42 are mounted on the outer side of the winding shaft 3 .

[0032] The first rotating disk 5 has an annular protrusion 51 in the center thereof, which extends axially toward the first baffle 6 . The cloth roll 100 is sleeved on the outer side of the annular protrusion 51 .

[0033] One side of the pad 9 is embedded in the first vertical plate 41 and connected to the first vertical plate 41 via bolts, and the surface of the other side of the pad 9 protrudes from the side surface of the first vertical plate 41 .

[0034] The bottoms of the first vertical plate 41 and the second vertical plate 42 are fixedly connected to the bottom plate 1 by bolts.

[0035] The working principle of the utility model is as follows:

[0036] In the initial state, the spring continuously squeezes the cloth roll to prevent the cloth roll from rotating itself;

[0037] During use, the rewinding shaft rotates to rewind the cloth segment that has been wiped with residual glue, thereby driving the cloth roll on the unwinding shaft to rotate and provide a new cloth segment for wiping glue. In the above process, the movement of the cloth roll produces a position deviation, thereby squeezing the spring, and the spring applies pressure to the cloth roll, which can not only increase the squeezing force between the first rotating disk and the pad, but also prevent the rotating disk from being subjected to force during the process and producing unnecessary rotation, thereby improving the position accuracy and stability of the rubber wiping cloth segment.
