[0024] The knife group 34 includes a second cylinder 344 connected and fixed to the top of the movable block 32, and the output end of the second cylinder 344 is connected to a lower connecting plate 343, and the top of the lower connecting plate 343 is connected to an upper connecting plate 342 through bolts, and the top of the upper connecting plate 342 is connected to a cutting blade 341, and a rectangular block end is provided at the bottom end of the upper connecting plate 342, and the rectangular block end is embedded in the surface of the lower connecting plate 343 through a groove, and a rubber sleeve 345 is provided on the outer side of the second cylinder 344.
[0025] A slider 22 is connected to the bottom end of a plate group 21 on the right side, and the slider 22 is embedded in the fixed plate 24 through a guide groove, and a first cylinder 23 is connected to the right side of the slider 22: the plate group 21 includes a vertical plate 211, and an insertion shaft 212 is connected to the inner wall of the vertical plate 211, and a plurality of rubber rings 215 are equidistantly connected to the outer side of the insertion shaft 212, a push rod 213 is rotatably installed on the left side of the insertion shaft 212, and a support spring 214 is connected to the inner wall of the push rod 213, and the bottom end of the support spring 214 is connected and fixed to the insertion shaft 212.
[0026] The bucket-shaped expansion design of the guide frame plate 43 can facilitate the collection of the blown residual yarn, which is simple and convenient to clean and can quickly remove the fallen residual yarn. The upper connecting plate 342 can be controlled to move by the extension and contraction of the input end of the second cylinder 344, and then the position of the cutting blade 341 can be changed. The cutting blade 341 can rise to a suitable position, which is convenient for cutting the original yarn outside the yarn tube, so that the cutting blade 341 can be adapted to yarn tubes of different sizes. When the upper connecting plate 342 is docked with the lower connecting plate 343, the rectangular block end at the bottom end of the upper connecting plate 342 can be embedded in the groove of the lower connecting plate 343, which is convenient for positioning the installation of the upper connecting plate 342.

The movement of the slider 22 can push the vertical plate 211 to move, and then the vertical plate 211 on the right side pushes the rubber ring 215 to move, and then inserts it into the yarn tube. At this time, the resilience of the support spring 214 can push the push rod 213 to rotate, so that the push rod 213 can be pressed against the inner wall of the yarn tube for fixation;
[0028] Secondly, according to the attached Figure 2 With attached Figure 4 As shown, the motor 33 is started, so that the output end of the motor 33 drives the threaded shaft 31 to rotate. The threaded shaft 31 can drive the movable block 32 to move in the guide groove of the base 1 during rotation. The movable block 32 can control the cutting blade 341 to cut the original yarn on the surface of the yarn tube during movement, so as to remove the original yarn. The residual yarn generated during cutting is blown by the wind force generated by starting the blower 42, so that the residual yarn is blown out from the guide frame plate 43.
