[0047] The working principle of the utility model is as follows:

[0048] Each time it is used, a new cloth roll is first installed on the unwinding shaft, and one end of the cloth roll is wound and fixed on the rewinding shaft, so that the lower surface of a section of the cloth contacts the sponge block on the L-shaped movable block;

[0049] Afterwards, the movable block is driven downward by the vertical cylinder, and the horizontal part of the movable block presses the pressing plate of the pressing bottle downward, and the alcohol in the pressing bottle is pumped to the upper surface of the pressing plate and absorbed by the sponge block, and then transmitted to the rubber cloth section through the sponge block. Then, the nozzle to be wiped is moved to contact with the upper surface of the rubber cloth section, that is, the rubber cloth section soaked with alcohol can wipe the residual glue on the nozzle. Because of the compatibility between alcohol and residual glue, the efficiency and effect of wiping the residual glue can be improved;

[0050] After one wiping is completed, the vertical cylinder drives the movable block to move upward, and the horizontal part of the movable block no longer presses the pressing bottle, thereby avoiding the volatilization waste caused by long-term exposure of alcohol and the decline of wiping effect.

[0051] Next, the reel-up shaft rotates to reel up the cloth segment that has been wiped with the residual glue, thereby driving the cloth roll on the unwinding shaft to rotate to provide a new cloth segment for wiping the glue.

[0052] When the above-mentioned automatic glue erasing and dispensing machine is used, it can not only wipe the residual glue with the eraser cloth segment soaked in alcohol to improve the effect of erasing the residual glue, but also effectively avoid the waste caused by the volatilization of alcohol during long-term use, and can also ensure that the amount of alcohol on each eraser cloth segment during continuous wiping is sufficient and consistent, thereby improving the efficiency and effect of glue erasing; further, it can avoid the position deviation caused by the winding process of the cloth segment, resulting in insufficient contact between the nozzle and the eraser cloth segment, thereby improving the quality and effect of glue erasing.

[0053] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
