Embodiment 1

[0047] Production line speed 70m / min; product category: T300-3K raw yarn; number of spinning positions: 36; cylinder pressure: 3bar; rubber roller covering 15mm, hardness HRC = 65. After the above-mentioned zero-degree calibration is completed and the tow passes through, the cylinder pressure is controlled to 3bar, and the passive rubber roller is controlled to be lowered until the deformation of the passive rubber roller is 1mm, and then the screws of the two sets of worm lifts are fine-tuned to rise by 1mm. By sampling and testing the tow, the results show that the oil content of the tow is basically the same.

[0048] The results are shown in the table below:

[0052] Production line speed 80m / min; product category: T700-12K raw yarn; spinning position: 24; cylinder pressure: 3.2bar; rubber roller covering 15mm, hardness HRC=45. After the above-mentioned zero-degree calibration is completed, after the tow passes, the cylinder pressure is controlled to 3.2bar, and the passive rubber roller is controlled to be lowered until the deformation of the passive rubber roller is 2mm, and then the screws of the two sets of worm lifts are fine-tuned to rise by 2mm. By sampling and testing the tow, the results show that the oil content of the tow is basically the same.

Abstract

The invention discloses a compression roller device for controlling the oiling rate of protofilament. The device comprises a cantilever beam and at least one fixed support suspension beam; the bottom surface of the cantilever beam is connected with fixed supports in the length direction of the cantilever beam; the number of the fixed supports is the same as that of the fixed support suspension beams; the middle of each fixed support suspension beam is rotationally connected with the bottom end of the fixed support at the corresponding position; the fixed support suspension beams are arranged in the width directions of the cantilever beams; a driven rubber compression roller is connected to the fixed support suspension beams; driving metal rollers are arranged at the bottom of the driven rubber compression rollers; one side of the cantilever beam is connected with an air cylinder coarse adjustment device, and the other side of the cantilever beam is connected with a fine adjustment device; the working end of the air cylinder coarse adjustment device is connected with the head ends of the fixed support suspension beams; and the working end of the fine adjustment device is connected with the tail ends of the fixed support suspension beams. The consistency of deformation of the two ends of the driven compression roller is guaranteed, then the stresses of tows inside and outside an oil groove are controlled to be consistent, and the oiling rate is finely controlled to be uniform.

Description

technical field [0001] The invention relates to the technical field of preparation of PAN-based carbon fiber precursors, in particular to a pressing roller device for controlling the oiling rate of precursors. Background technique [0002] Precursor is the raw material of PAN carbon fiber, and its performance will directly affect the quality of carbon fiber. The oiling process is the key process in the raw silk preparation process. When the oiling rate of the raw silk is too high, the raw silk is prone to parallel silk during the pre-oxidation process, the ash content increases, and the by-products such as tar and silicon powder increase, resulting in a shortened production cycle. , product quality declines, serious safety production accidents occur; when the oiling rate of the raw silk is too low, the oil agent cannot form an oil film on the fiber surface evenly, and cannot protect the raw silk during pre-oxidation, resulting in fiber burnout and pre-oxidized silk. In the ...
