Specifically, the outer side of the air outlet box 41 is fixedly connected with a second vent pipe, the bottom surface of the second vent pipe is located on the inner side of the fixed outer box 35, and a control valve is fixedly mounted on the outer side of the second vent pipe, so that the mechanism 3 is prevented from being influenced by the air blowing process during sizing control.

The working process of the invention is as follows:

the first step is as follows: injecting sufficient size into the inner cavity of the upper size box 1, rotating a threaded rod, rotating the threaded rod to drive a lifting sliding block 55 to slide on the inner side of a vertical sliding groove 54, further driving a sliding compression roller 53 to slide on the inner side of a fixed compression roller 51, and changing the distance between the bottom surface of the sliding compression roller 53 and the top surface of the fixed compression roller 51 so that yarns enter a gap between the fixed compression roller 51 and the sliding compression roller 53;

the second step is that: the yarns penetrate through the top surface of the elastic pressing groove 62, the conveyor belt 63 rotates to drive the sponge block 61 to rotate, so that the yarns and the sponge block 61 are in friction collision with each other, when the yarns are located on the inner side of the elastic pressing groove 62, along with the rotation of the sponge block 61, the yarns slide out of the inner side of the elastic pressing groove 62 and then enter, sponge columns between the elastic pressing grooves 62 are subjected to elasticity to generate deformation and collide with the yarns, dust is bounced, the turbine air pump 4 starts to admit air through the air inlet pipeline 42, suction force generated by air admission of the pressure roller mounting rod 52 absorbs the bounced dust, the dust enters an inner cavity of the filter box 64 and collides with the outer surface of the gauze layer 641, and further slides into the inner cavity of the dust collection box 642;

the third step: the yarn enters the inner cavity of the sizing box 1 and is abutted against the top surface of the abutting roller 31, the turbine air pump 4 is started to ventilate the inner cavity of the air outlet box 41, the control valve is opened, air flow enters the inner cavity of the pneumatic assembly 34, air pressure in the inner cavity of the pneumatic assembly 34 is increased to push the pneumatic assembly 34 to move downwards, the limiting clamping ball 341 slides out of the inner side of the limiting through groove 33 to drive the telescopic spring 342 to compress, the distance between the limiting clamping balls 341 is reduced, the pneumatic sliding rod 343 moves to drive the pressing roller connecting shaft 32 to move and further drive the abutting roller 31 to move up and down, when the yarn moves between the other pair of limiting through grooves 33, the telescopic spring 342 restores to extrude the pneumatic sliding rod 343 to extend towards two sides, and the limiting clamping ball 341 and the limiting through grooves 33 are clamped and fixed with each other;

the fourth step: when the yarns are sized, the turbine air pump 4 ventilates the inner side of the air pipe mounting hole 25 through the vent pipe, air flow enters the inner cavity of the air blowing plate 22 through the ventilation header box 21, then a plurality of bubbles are generated through the air groove through holes 23 to drive slurry to be mixed, after sizing is finished, the sized yarns enter between the fixed compression roller 51 and the sliding compression roller 53, and redundant slurry drops into the inner cavity of the sizing box 1 through the extrusion effect of the fixed compression roller 51 and the sliding compression roller 53.
