The working principle is as follows: the waste materials scraped by the scraper ring plate 5 are sucked into the cavity 32 under the action of the negative pressure fan 14, the detector 4 sends a signal to the repair switch 13 when a crack gap exists on the yarn 1, so that the repair switch 13 is closed, the power supply 12 supplies power to the heater 10, the heater 10 works and emits a large amount of heat, the heater 10 heats the cavity 32, the waste materials are melted, the evaporation liquid is evaporated and expanded and pushes the piston push plate 8 to move towards the direction close to the yarn 1, and the elastic connecting rod 9 is elastically deformed and elongated;
the piston push plate 8 drives the push rod 7 to move towards the direction close to the yarn 1 under the pushing of the evaporation gas, the striker plate 15 is fixed on the inner wall of the cavity 32 and keeps still until the two semi-ring through grooves 61 are mutually attached and tightly attached to the outer side of the yarn 1, the striker plate 15 leaves the feed groove 72, the melted waste material enters the feed groove 71 through the feed groove 72, the melted waste material in the feed groove 71 enters the semi-ring through grooves 61 under the suction force of the semi-ring through grooves 61 and is coated on the yarn 1 with crack gaps, and the crack gaps of the yarn 1 are repaired;
after the repaired yarn 1 leaves the pressing plates 6, the detector 4 stops transmitting signals to the repair switch 13, so that the control circuit is disconnected again, the heater 10 stops heating, the evaporation gas is liquefied again at the external temperature to form evaporation liquid, the air pressure is reduced, the piston push plate 8 moves reversely under the elastic action of the elastic connecting rod 9 to reset, the two pressing plates 6 are separated from each other, the material baffle plate 15 blocks the feeding groove 71 again, the yarn 1 is conveyed continuously and passes through the scraper ring plate 5, and the scraper ring plate 5 scrapes off burr protrusions of the yarn 1.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
