[0025] The powder spreading mechanism 8 comprises a frame, a powder trough is provided at the upper end of the frame, a flower roller and a brush roller are arranged side by side in the powder trough, the two are arranged to rotate relatively, a baffle is provided at the lower end, a plurality of cloth guide rollers are provided in the middle of the frame, the baffle is in contact with the yarn on the cloth guide roller, and a powder receiving hopper is provided at the lower part.

[0026] The automatic deviation-correcting paper-feeding mechanism 11 comprises a frame, a linear guide is provided at the upper end of the frame, a paper-feeding device is slidably provided on the linear guide, a deviation-correcting actuator for correcting the position of the paper-feeding device is connected to one side of the paper-feeding device, the paper-feeding device comprises a servo motor, an air-expanding shaft is provided at the output end of the servo motor, and a release paper is sleeved on the air-expanding shaft.

[0027] The constant tension winding mechanism 12 includes a frame, one end of a tension swing arm is installed on the upper end of the frame through a tension swing arm rotating shaft, and the other end is provided with a yarn guide roller.

[0029] Working process: large tow carbon fiber yarn needs to be sorted by a yarn collecting frame 1 and a yarn dividing machine 3. A preheater 2 is set between the two to heat the yarn, which can melt the binder contained in the carbon fiber and make the yarn have better dispersion. Then, the yarn is shaken up and down at high speed by a shaking dispersion device 4 to make the fiber evenly spread out to prepare for subsequent work. Then, the yarn is widened by a widening mechanism A5 and a widening mechanism B6 to form a yarn sheet with uniform gram weight. The yarn sheet is pulled out of the widening mechanism under the action of a three-roller pulling mechanism 7. At the same time, the water cooling roller 10 has an active cooling function. Therefore, the fiber binder heated and melted before is solidified, causing the yarn sheet to be shaped. A powdering mechanism 8 is set for the yarn sheet that is not fully solidified again. After powdering, heating and cooling, the yarn sheet is finally formed and wound on the disc head under the action of a constant tension winding mechanism 12 and an automatic deviation correction and paper release mechanism 11. The lightest yarn sheet of this equipment can produce 50 grams / square.
