The external air supply system is the prior art.

Referring to fig. 4 and 5, considering that drying cylinder 16 is only capable of heating one side of the yarn, it takes time for heat to transfer to the other side of the yarn. The bottom of the heating pipe 18 is communicated with a plurality of heating pipes 24, one end, far away from the heating pipe 18, of the heating pipe 24 is communicated with the inside of the roller 15, the heating pipe 24 and the through holes 19 are arranged in a staggered mode, a plurality of air outlet pipes 25 are fixedly communicated with the inner wall of the roller 15, a plurality of air outlet holes 26 are formed in the outer peripheral surface, close to the infusion pipe 14, of the air outlet pipes 25, each air outlet hole 26 is circumferentially distributed along the outer side of the air outlet pipe 25, and accordingly the inside of the roller 15 can be communicated with the outside through the air outlet holes 26.

The hot air is introduced into the heating pipe 18 through an external air supply system, enters the roller 15 through the heating pipe 24, and then flows to the outer side of the roller 15 through the air outlet 26, so that the hot air can preheat the other side of the yarn outside the roller 15, the yarn can be heated while being contacted with the decoloring agent, and the decoloring speed of the decoloring agent on the yarn is improved. The external air supply system is the prior art.

Referring to fig. 4 and 7, further, an elastic blocking component 27 is installed at one end of the air outlet pipe 25 near the infusion tube 14, a small cam 28 is installed at the lower half position outside the infusion tube 14, the small cam 28 is arranged in a semicircular arc, a large cam 29 is installed at the upper half position outside the infusion tube 14 near the drying cylinder 16, the large cam 29 is arranged in a quarter arc, and the outer side of the infusion tube 14, the small cam 28 and the large cam 29 can be matched with the elastic blocking component 27. The thickness of the large cam 29 is larger than the thickness of the small cam 28.

Referring to fig. 7, the elastic blocking component 27 includes a slide bar 30, an arc-shaped baffle 31, a blocking spring 32 and a blocking cylinder 33, wherein one end of the air outlet tube 25 close to the infusion tube 14 is an opening, the slide bar 30 is slidably connected to one end of the air outlet tube 25 close to the infusion tube 14, the slide bar 30 completely blocks the opening of the air outlet tube 25, the blocking spring 32 is fixedly connected between the slide bar 30 and the air outlet tube 25, the arc-shaped baffle 31 is fixed to one end of the slide bar 30 close to the infusion tube 14, the blocking cylinder 33 is fixed to one end of the arc-shaped baffle 31 close to the air outlet tube 25, the blocking cylinder 33 is slidably sleeved on the outer side of the air outlet tube 25, the inner side of the blocking cylinder 33 is attached to the outer side of the air outlet tube 25, and the blocking cylinder 33 is used for blocking the air outlet hole 26.

In this embodiment, the screws are countersunk screws to reduce contact between the arcuate baffles 31 and the screws.

It should be noted that, dividing the small cam 28 into a plurality of detachable protruding pieces, the thickness of the small cam 28 can be adjusted by adjusting the positions of the protruding pieces, so that the distance that the small cam 28 can push the arc baffle 31 to move can be adjusted, the number of the air outlet holes 26 blocked by the blocking cylinder 33 can be adjusted, considering that the speed of hot air in the input roller 15 may be greater than the speed of hot air output by the roller 15, the pressure increase in the roller 15 may occur, the speed that the hot air pushes the decolorizing agent in the pinhole 21 to flow easily occurs after the pressure increase, the decolorizing agent in the cavity 22 is easy to permeate the surface of the roller 15, at this time, the number of protruding pieces can be reduced to reduce the thickness of the small cam 28, more air outlet holes 26 are in a communicating state, the pressure increase in the roller 15 is difficult to occur, and in practical use, the speed that the decolorizing agent in the pinhole 21 flows out can be adjusted in this way.

In addition, in order to make the decolorizing agent in the through holes 19 and the hot air in the heating pipe 18 smoothly enter the roller 15, the positions of each protruding sheet corresponding to the through holes 19 are provided with the through holes 34, and the through holes 34 are located right below the through holes 19. It should be noted that, the arc baffle 31 and the through hole 19 are arranged in a staggered manner, so that the arc baffle 31 and the flow hole 34 are arranged in a staggered manner, and the arc baffle 31 can not block the flow hole 34 during movement, so as to ensure that the decoloring agent and hot gas smoothly fall.

When the sized and dried yarns pass through the folding mechanism, each branching rod 37 equally divides the yarns into an upper part and a lower part, so that the bonded yarns are separated from each other, the phenomenon that the yarns are bonded together is reduced, and the subsequent yarns are conveniently woven.

Referring to fig. 11, the comb sub-assembly 38 is mounted at the folding stage 35, the comb sub-assembly 38 includes a driving member 40, a comb sub-base frame 41 and a comb sub-assembly 42, a base plate 43 is fixed at the bottom of the folding stage 35, the base plate 43 is used for supporting the whole folding stage 35, in this embodiment, the driving member 40 is an air cylinder, the driving member 40 is vertically fixed at the top of the base plate 43, and the driving member 40 is located between the folding stage 35 and the folding roller 36, the comb sub-base frame 41 is fixed at the output end of the driving member 40, the comb sub-assembly 42 is fixed at the top of the comb sub-base frame 41, the comb sub-assembly 42 is composed of a plurality of vertically arranged comb teeth, and the comb sub-assembly 42 composed of the comb teeth is in a wave shape as a whole.
