Technical Field

[0001] The utility model patent relates to the technical field of carbon fiber production equipment, in particular to a carbon fiber filament cleaning device for carbon fiber weaving. Background Art

[0002] In the process of carbon fiber production, the inevitable single fiber breakage (5-10 microns) defects of the raw material PAN precursor itself and the single fiber breakage hairs inevitably generated by reactions during the carbon fiber preparation process or friction with the equipment will have a certain impact on the apparent quality of the subsequent carbon cloth preparation.

[0003] In the process of carbon fiber weaving, hair and lint are inevitably produced when the tow passes through the warp frame and the warp holes. In the previous operation process, manual supervision is required. If problems are found, the machine must be stopped and manually cleaned. During the operation, slight damage to the carbon filaments is inevitable. At the same time, the fallen hair pollutes the production environment and affects the health of the operators.

[0004] The existing Chinese invention patent CN109505036 is titled "A device for processing lint on the surface of a grooved roller for carbon fiber production." It proposes a solution to the problem of installing the device on the outside of the grooved roller for carbon fiber production and using a scraper blade to remove broken fibers and lint on the grooved roller. The device can only process lint on single-sided fibers, and because the sponge itself has low strength, the cleaning between the electrostatic delinting brush and the sponge can easily damage the sponge, and the resulting sponge debris can easily mix into the fiber bundle.

[0005] Therefore, it is urgent to invent a carbon fiber cloth carbon filament cleaning device to solve the above problems. Utility Model Content

The tension roller 2 4 is arranged at the lower part of the bracket 1, and the tension roller 2 4 is rotatably connected to the bracket 1. When the carbon cloth passes through the tension roller 1 3 and the tension roller 2 4, the tension roller 1 3 and the tension roller 2 4 are driven to rotate. There are two sinking and floating rollers 5, and the sinking and floating rollers 5 are bolted and fixed to the middle part of the bracket 1. When the carbon cloth passes through the sinking and floating rollers 5, the carbon cloth and the sinking and floating rollers 5 rub to remove the fiber lint on the carbon cloth. Wire suction barrels 6 are respectively provided on both sides of the bracket 1, and accommodating chambers 7 are provided on the outside of the wire suction barrels 6. The accommodating chambers 7 collect the silk threads absorbed by the wire suction barrel 6 to facilitate subsequent cleaning.

[0027] In some embodiments, circular holes are provided at the upper and lower ends of the bracket 1, and bearings are fixedly connected in the circular holes. The diameters of the bearings correspond to the tension roller 1 3 and the tension roller 2 4, and the tension roller 1 3 and the tension roller 2 4 are movably connected to the bracket 1 through the bearings.

[0028] In some embodiments, the inner side of the sinking and floating roller 5 is a square support rod 8, the outer side of the square support rod 8 is glued and wrapped with a sponge 9, and a gold velvet cloth 10 is provided on the outer side of the sponge 9. The two ends of the square support rod 8 are "I" shaped structures.

[0029] In some embodiments, a gold velvet cloth 10 is provided on the outside of the sponge 9. The sponge 9 adopts a 60d sponge 9. The sponge hardness of the 60d sponge 9 is suitable for cleaning fiber filaments. The gold velvet cloth 10 adopts a thickened gold velvet cloth. The thickened gold velvet cloth prevents the carbon cloth thread from piercing the sponge 9. At the same time, the hair or hair balls are removed during the carbon cloth cleaning process, thereby increasing the wear resistance of the sinking and floating roller 5.

[0030] In some embodiments, as Figure 5 As shown, the fixing frame 2 is in a concave shape, and a threaded hole is provided on the horizontal surface of the fixing frame 2. The fixing frame 2 is inserted into the square hole of the bracket 1. The fixing frame 2 is bolted to the bracket 1 by a fixing bolt 11. The fixing bolt 11 squeezes the sinking and floating roller 5 to fix the sinking and floating roller 5.

[0031] In some embodiments, the tension roller 1 3 and the tension roller 2 4 are cylindrical structures. A rotation sensing switch 12 is provided on the left side of the tension roller 1 3 . When the rotation sensing switch 12 detects that the tension roller 1 3 is rotating, the rotation sensing switch 12 is activated.

[0032] In some embodiments, as Figure 3As shown, the wire suction barrel 6 is a "convex" through-hole structure, a relay switch 13 is provided inside the wire suction barrel 6, a guide rail 14 is provided on the outside of the wire suction barrel 6, the relay switch 13 is electrically connected to the rotation sensing switch 12, when the rotary switch rotates, the rotary switch drives the relay switch 13 to start, and the relay switch 13 controls the rotation of the fan 19.

[0033] In some embodiments, as Figure 4 As shown, a groove 16 corresponding to the guide rail 14 is provided on the front side of the accommodating chamber 7, a filter plate 17 is provided in the accommodating chamber 7, an air vent 18 is provided on the back side of the accommodating chamber 7, and a fan 19 is provided between the left side of the air vent 18 and the filter plate 17. The accommodating chamber 7 is slidably connected to the wire suction barrel 6 through the guide rail 14. The fan 19 in the wire suction barrel 6 rotates to suck the cleaned fiber hair and hair balls into the inside of the fan 19, and the fiber hair and hair balls are filtered by the filter plate 17 and accumulated in the wire collecting bin 15.

[0034] Example 1

[0035] In a specific embodiment provided by the present invention, Figure 1-Figure 5 As shown, this device needs to be installed on a horizontal platform. The carbon cloth to be cleaned passes under the tension roller 2 4 of the equipment, then crosses between the middle sinking and floating roller 5 and the tension roller 1 3, and then passes out from the upper part of the tension roller 1 3. Since the sinking and floating roller 5 is fixed, the carbon cloth is ground and pressed twice by the sinking and floating roller 5 to achieve the cleaning of fiber filaments on both sides of the carbon cloth.

[0036] The carbon cloth is driven forward by the equipment, and the movement of the carbon cloth drives the tension roller 1 3 and the tension roller 2 4 to rotate. The rotation of the tension roller 1 3 drives the rotation sensing switch 12 to turn on. The rotation sensing switch 12 transmits an electrical signal to the relay switch 13 to drive the relay switch 13 to turn on. The relay switch 13 transmits an electrical signal to the fan 19 to control the fan 19 to turn on. The fan 19 rotates to generate suction to absorb the fiber hair and hair balls that fall off during the cleaning of the carbon cloth. The hair and hair balls are absorbed by the wire suction barrel 6 and reach the filter plate 17. Under the filtration of the filter plate 17, the hair and hair balls are collected in the wire collecting bin 15. When the hair and hair balls accumulate to a certain amount, they can be cleaned manually.
