Description

A carbon filament attachment cleaning device

Technical Field

The invention relates to the field of carbon fiber production equipment, and in particular to a carbon filament attachment cleaning device.

Background technique

Carbon fiber materials are used in a wide range of technical fields. They have many excellent properties and are indispensable materials in life and industrial production. The production of carbon fiber prepreg requires pretreatment of carbon fiber filaments, which are also referred to as carbon filaments. They are described as "carbon filaments" below. According to actual needs, the treated carbon filaments are prepared into carbon fiber yarns, which are then coated, hot pressed, cooled, coated, and rolled up to finally be prepared into carbon fiber prepreg.

Before the carbon filaments are spun, it is necessary to clean the impurities attached to the raw materials of the carbon filaments, such as crushed fiber particles, short fiber segments and other attachments, commonly known as the "brushing" process. If this step is not performed, the subsequent production will be directly affected by impurities. At present, the brushing operation is performed manually, with the staff holding a long brush. As the carbon filaments are pulled out from the material rack, the staff are located at the bracket or the feed inlet of the subsequent production equipment to brush the carbon filaments. The brush used by the staff is very simple, usually made of an iron wire with gauze or cotton wrapped around the end of the iron wire. When brushing, it is necessary to pay attention to cleaning each carbon filament as much as possible. Therefore, it takes multiple workers to operate, and it is more energy-consuming to operate.

Example 1

1 to 6 , the present invention provides a carbon filament attachment cleaning device, comprising a wire arranging mechanism 1, a bristle brush mechanism 2, and a wire clamping mechanism 4 which are arranged in sequence;

The wire-managing mechanism 1 includes two wire-managing rollers arranged upper and lower, and a plurality of slots arranged in an array along the axial direction of the roller body are formed between the two wire-managing rollers. The number of slots corresponds to the number of carbon filaments separated by the wire-dividing plate 101 on the material rack 100. The wire-dividing plate 101 is a plate body arranged on the carbon filament-dedicated material rack 100. A plurality of rows of threading holes are arranged in an array on the plate body of the wire-dividing plate 101. The threading holes are used for passing out the carbon filaments. The projections of the plurality of rows of threading holes on the horizontal plane are staggered. This structure is mainly to prevent the carbon filaments from being entangled during discharging. The carbon filaments separated by the wire-dividing plate are respectively embedded in the slots on the wire-managing rollers through the wire-managing rollers of the wire-managing mechanism. On the one hand, the carbon filaments are also prevented from being entangled. On the other hand, the carbon filaments are gathered on a plane to facilitate the subsequent brushing mechanism 2 to clean the carbon filaments.

The bristle mechanism 2 includes at least one bristle belt group, each bristle belt group includes at least one bristle belt 21, the bristle belt 21 is an annular belt body, the bristle belt 21 is driven to rotate by a driving roller 22, and a strip-shaped brush 24 is fixedly arranged on the outer side of the bristle belt 21; the wire-straightening mechanism 1 guides the carbon filament to the bristle mechanism 2, and the carbon filament passes through the bristle belt 21 that keeps rotating. As the bristle belt 21 rotates, the brush 24 follows and moves, thereby cleaning the carbon filament.

The clamping mechanism 4 includes two clamping rollers 41 arranged in parallel with each other, and the end faces of the clamping rollers 41 on opposite sides are in contact with each other. The clamping rollers 41 are used to clamp the carbon filaments passing through. Because the cleaning method of the brushing mechanism 2 may cause vibration and displacement of the carbon filaments, the structure of the clamping rollers 41 is used to limit the carbon filaments to a certain extent, thereby reducing the impact of the brushing mechanism 2.

Example 2

On the basis of Example 1, the two wire-straightening rollers of the wire-straightening mechanism 1 are respectively a fixed roller 11 and a movable roller 12, and the roller shaft of the fixed roller 11 is fixedly arranged on one side of the bracket 5 close to the material rack 100;

The movable roller 12 is arranged below the fixed roller 11; both ends of the shaft of the movable roller 12 are connected to the lifting block 13, and the lifting block 13 is connected to the bracket 5 through the lifting mechanism.

The lifting mechanism includes a lifting motor 14 fixedly arranged on the upper side of the bracket 5 . The motor shaft of the lifting motor 14 is coaxially and fixedly connected to a vertically arranged roller screw 15 . The roller screw 15 is threadedly connected to the lifting block 13 .

A plurality of disc-shaped blocks are arranged in an array on the roller body of the fixed roller 11, and the disc-shaped blocks are arranged in an axial linear array along the fixed roller 11;

One end of the disc-shaped block away from the axis of the fixed roller 11 is ridge-shaped;

Annular grooves are arranged on the roller body of the movable roller 12 corresponding to the disc block array. The end of each annular groove away from the movable roller 12 is a large opening end. The distance between the two inner walls of the groove gradually decreases toward the axis of the movable roller 11. The longitudinal section of the groove is "V" shaped.

Through this structure, under the action of the lifting motor 14, the movable roller 12 first moves away from the fixed roller 11, and the carbon filament passes between the fixed roller 11 and the movable roller 12. Under the action of the lifting motor 14, the movable roller 12 rises, and because of the shape of the groove on its roller body, the carbon filament is gradually guided and gathered to the inner side of the groove closest to the roller axis of the movable roller 12; at this time, the movable roller 12 contacts the fixed roller 11, and the ridge-shaped protrusion of the disc-shaped block on the fixed roller 11 is embedded in the groove of the movable roller 12, clamping the carbon filament, thereby completing the separation and sorting of the carbon filament.

Example 3

On the basis of the above-mentioned embodiment, a driving roller 22 and a driven roller 23 are respectively arranged inside each bristle belt 21 , and the driving roller 22 and the driven roller 23 are rotatably connected to the bracket 5 .

Each bristle belt group includes two bristle belts 21;

Two bristle belts 21 are respectively arranged on the upper side and the lower side of the path through which the carbon filament passes;

The driving rollers 22 of the two bristle belts 21 have opposite rotation directions.

The driving roller 22 and the driven roller 23 stretch the bristle belt 21 into a ring shape, which includes two parallel straight line parts, and arc parts at both ends of the straight line parts.

The straight portion of the bristle belt 21 is in contact with the carbon filament group;

The brushes 24 are distributed in a spiral strip shape on the outside of the brush belt 21 .

With this structure, the brush 24 rotates with the brush belt 21 under the rotation of the driving roller 22, so the brush 24 can rub against all carbon filaments in a continuous strip. The two brush belts 21 are used to brush the carbon filaments from the upper and lower sides and rotate in different directions, which can offset the carbon filament deviation caused by the brush 24 when contacting the carbon filament to a certain extent.

Example 4

On the basis of the above embodiment, the clamping roller 41 comprises a cylindrical roller body in the middle, and a plurality of raised pressure strips 42 are evenly distributed in a circumferential array on the circumference of the cylindrical roller body, and the pressure strips 42 are arranged along the axis of the clamping roller 41;

The end surface of the layer strip 42 away from the axis of the cylindrical roller body is an arc surface, and the axis of the arc surface of the layer strip 42 is coaxial with the axis center line of the cylindrical roller body.

Through this structure, the clamping roller 41, with the help of the structure of the pressure strip 42, has a number of high-strength clamping of the carbon filaments corresponding to the number of pressure strips 42 in each circle of the clamping roller 41. Because in the production process of carbon fiber prepreg, the carbon filament is the initial end of the production line, and there is a wire drawing device in the subsequent process to continuously input the carbon filament into the production line. This device is combined with the existing production line. When the production line itself has a feeding pulling force for the carbon filament, the structure of the pressure strip 42 is combined with the clamping roller 41. When the upper and lower clamping rollers 41 rotate until the pressure strip 42 abuts against each other, on the one hand, it has a better stabilizing effect on the carbon filament and reduces the vibration of the brush 24 on the carbon filament. On the other hand, through the rotation of the clamping roller 41, the carbon filament is also driven to move in the direction of the subsequent production line operation.

Example 5

On the basis of the above embodiment, a wire-pulling mechanism 3 is further provided between the bristle-brushing mechanism 2 and the wire-clamping mechanism 4;

The wire pulling mechanism 3 includes a pulling tooth 31 arranged on one side of the wire clamping mechanism 4. The pulling tooth 31 is a long strip-shaped tooth plate. The upper edge array of the pulling tooth 31 is provided with teeth with pointed upper ends.

The long axis of the shifting tooth 31 is parallel to the long axis of the clamping roller 41;

The shifting tooth 31 is located at the lower side of the carbon filament, and the shifting tooth 31 performs horizontal reciprocating motion under the drive of the shifting tooth motor 32 .

The number of the side teeth on the shifting tooth 31 corresponds to the number of the carbon filaments.

Under the action of the shifting teeth 31, the teeth cause the carbon filament to vibrate through reciprocating motion. Combined with the wire clamping mechanism 4, when the pressure strips 42 of the upper and lower clamping rollers 41 abut against each other, a relatively large force is provided to the carbon filament to maintain stable clamping. Under the action of this force, the shifting teeth 31 can have a better vibration effect on the fluctuation of the carbon filament, making it easier for impurities on the carbon filament to be vibrated and to be more easily separated from the carbon filament.

Combined with the specific structure of the aforementioned clamping roller 41, when the pressure strip 42 of the clamping roller 41 clamps the carbon filament, the amplitude of the carbon filament facing the material rack 100 increases due to the extrusion and positioning of the pressure strip 42. As for the side of the clamping roller 41 away from the material rack 100, that is, the part of the carbon filament entering the subsequent process after the brushing, the vibration of the carbon filament in the subsequent process is reduced to a certain extent through the clamping of the pressure strip 42.

Example 6

The gear shifting frame 33 can be connected to the bracket 5 via a frame screw rod 34 at both ends, or a frame screw rod 34 can be provided at one end and a guide rod can be provided at the other end.

Through this structure, the height of the shifting tooth 31 can be adjusted by adjusting the height of the shifting tooth frame 33. The lower the position of the shifting tooth 31 is, the shorter the contact time with the carbon filament is, and the smaller the vibration force of the carbon filament is. Conversely, the higher the height of the shifting tooth 31 is, the greater the vibration force of the carbon filament is.

Example 7

Based on the above embodiment, the bracket 5 is connected to the rack rod of the material rack 100 through a U-shaped clamp 51 close to the side of the wire management mechanism 1. The U-shaped clamp 51 includes two parallel vertical plates, an intermediate plate located at one end of the vertical plates, and a horizontal through groove is opened on the plate body of the vertical plate, and a positioning screw passes through the through groove.
