A carbon fiber winding system and its laying method

Abstract

The present invention relates to the field of carbon fiber production technology, and more particularly to a carbon fiber winding system and its deployment method. The main functions of the guide roller and the traction roller are to pull the yarn, and the limiting ring grooves on the guide rollers serve to position the yarn. A row of vertical circular rollers on a yarn splitting comb splits the yarn guided by the traction roller, and the distributed yarn band is sent to the corresponding winder position, where the distributed yarn is wound by the winder. A plurality of yarn splitting combs arranged along the yarn conveying direction provide limited support for the yarn delivered to the matching winder, preventing the yarn from stacking and twisting during the suspended conveying process and standardizing the yarn conveying process on the guide winder. When feeding the yarn, all the yarn splitting combs are slid together to the side close to the traction roller, and the yarn is fed uniformly and centrally according to the yarn arrangement order. After the yarn is fed, each yarn splitting comb is moved in sequence along a first direction to the matching winder position, optimizing the winding effect of the winder.

Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber production, and in particular to a carbon fiber winding system and a laying method thereof. Background Art

[0002] In a carbon fiber winding system, the multiple carbon fiber yarns that are being guided need to be wound synchronously, using several winding machines to complete the winding operation. As the yarns are guided to the winding machines, they are transported in mid-air. This causes the state of the yarns corresponding to the winding machines located at a distance to be uncontrollable during the mid-air transportation process. This not only easily causes stacking and twisting between yarns or twisting of single filaments, but also the increased weight of the yarns themselves can affect normal winding, ultimately affecting the winding quality of the yarns.

[0013] Furthermore, the two slide rails are fixed on the top of the support frame, and the support frame is located between the winders on both sides.

[0014] Furthermore, the length of the yarn splitting comb is adapted to the position of the yarn guide wheel on the corresponding winding machine, and the lengths of the plurality of yarn splitting combs arranged along the first direction gradually decrease.

[0015] Furthermore, the two parallel slide rails are respectively fixed on the top of the frames of the winders on both sides.

[0021] Furthermore, the yarn feeding process of the winding system includes the following steps:

[0022] Move multiple yarn splitting combs to one end of the slide rail close to the traction roller;

[0023] Cooperate with the traction roller to guide the yarn out from the traction roller and evenly distribute it to multiple yarn distribution combs, and make the position of the yarn distributed to the yarn distribution comb match the position of the yarn guide wheel on the corresponding winding machine;

[0038] like Figures 1 to 6 A carbon fiber winding system shown includes a yarn guide roller 1, a traction roller 2, a yarn separation assembly 3 and a winder 4 arranged in sequence along a first direction, and the first direction is arranged parallel to the yarn conveying direction.

[0039] The yarn splitting assembly 3 includes a slide rail 31 arranged along a first direction and a yarn splitting comb 32 arranged perpendicularly thereto, the yarn splitting comb 32 being arranged parallel to the traction roller 2; a plurality of winders 4 are arranged side by side along the first direction and symmetrically arranged on both sides of the length of the yarn splitting comb 32, and a plurality of yarn splitting combs 32 are arranged corresponding to the plurality of winders 4; a support rod 41 and a yarn guide wheel 42 are arranged on the winder 4, the support rod 41 is located on the side of the winder 4 facing the slide rail 31 and is arranged along the second direction, the yarn guide wheel 42 is arranged on the support rod 41, and the plurality of yarn guide wheels 42 on the plurality of winders 4 arranged side by side in the first direction are staggered in the second direction, and the second direction is arranged perpendicular to the first direction. Among them, the yarn guide roller 1 is arranged parallel to the traction roller 2, and the traction roller 2 is driven to rotate by a power device, and a plurality of limiting ring grooves 11 are evenly arranged on the surface of the yarn guide roller 1 along its axial direction.

[0040] In the present invention, the main function of the yarn guide roller 1 and the traction roller 2 is to traction the yarn, wherein the limiting ring groove 11 on the yarn guide roller 1 also plays the role of yarn positioning; the yarn guided by the traction roller 2 is separated by a row of vertical circular rollers on the yarn separation comb 32, and the yarn separation comb 32 can move along the length direction of the slide rail 31 and send the distributed yarn belt to the corresponding winder 4 position, and the winder 4 rewinds the distributed yarn. By setting a plurality of yarn separation combs 32 along the yarn conveying direction, the yarn conveyed to the matching winder 4 is limited and supported, avoiding the phenomenon of stacking and twisting of the yarn during the suspended conveying process, and standardizing the conveying process of the yarn in the guide winder 4.

[0041] In this embodiment, the winder 4 is provided with a plurality of support rods 41, which are arranged at equal intervals along a first direction. A plurality of yarn guide wheels 42 are arranged along the first direction, gradually moving away from the winder 4, and the yarn guide wheels 42 are located at the end of the support rods 41 away from the winder 4. The yarn guide wheels 42 are staggered in the yarn conveying direction, and the staggered positions correspond to different axial positions of the traction roller 2, thereby preventing the yarn from being stacked and entangled during conveying and ensuring smooth long-distance suspended conveying of the yarn.

[0042] In this embodiment, the yarn splitting comb 32 is slidably connected to the slide rail 31, and a plurality of yarn splitting combs 32 are evenly arranged along the length direction of the slide rail 31. The yarn splitting comb 32 is located above the yarn guide wheel 42, and two slide rails 31 are provided in parallel.

[0043] Further, such as Figure 2 This is a schematic diagram of the layout of a yarn splitting assembly 3 in the carbon fiber winding system of the present invention. Two slide rails 31 are fixed to the top of a support frame 5, which is located between the two winding machines 4. The length of the yarn splitting comb 32 is adapted to the position of the yarn guide wheel 42 on the corresponding winding machine 4. The length of multiple yarn splitting combs 32 arranged along the first direction gradually decreases.

[0044] Further, Figure 3 This is a schematic diagram of another arrangement of a yarn splitting assembly 3 of a carbon fiber winding system of the present invention, wherein two parallel slide rails 31 are respectively fixed to the top of the frame 43 of the winding machine 4 on both sides. At this time, the yarn splitting combs 32 arranged above the frame 43 are of the same size.

[0045] The present invention further discloses a method for laying out a carbon fiber winding system, which uses the above-mentioned carbon fiber winding system and includes the following steps:

[0046] A plurality of winding machines 4 are provided in corresponding numbers according to the number of carbon fiber yarns, and the plurality of winding machines 4 are arranged in parallel along the yarn conveying direction, and are arranged in two opposite rows;

[0047] A yarn splitting assembly 3 is provided between two rows of winding machines 4, and a plurality of yarn splitting combs 32 are evenly arranged along the yarn conveying direction;

[0048] The yarn guide wheels 42 on the two rows of winders 4 are staggered so that the multiple yarn guide wheels 42 on the two rows of winders 4 correspond to different axial positions of the traction roller 2 respectively.

[0049] The yarn feeding process of the winding system includes the following steps:

[0050] Move multiple yarn splitting combs 32 to one end of the slide rail 31 close to the traction roller 2; cooperate with the traction roller 2 to lead the yarn out from the traction roller 2 and evenly distribute it to multiple yarn splitting combs 32, and make the positions of the yarns distributed to the yarn splitting combs 32 match the positions of the yarn guide wheels 42 on the corresponding winding machines 4; move the yarn splitting combs 32 and drive the yarns distributed on them to the corresponding winding machines 4, and then manually wind the yarns onto the corresponding winding machines 4.

[0051] In the convenient yarn feeding process of the winding system of the present invention, after the yarn is pulled out from the traction roller 2, it needs to pass through the yarn separation combs 32 in sequence along the first direction and then be pulled to each winding machine 4. Since there are a large number of yarn separation combs 32 for fixing the yarn, the normal yarn feeding process is too cumbersome and inconvenient. Therefore, a slide rail 31 is designed, and the yarn separation combs 32 can slide freely on the rail. When feeding the yarn, all the yarn separation combs 32 are slid together to the side close to the traction roller 2, and the yarn is fed uniformly and centrally according to the yarn arrangement order and the yarn separation combs 32. After the yarn is fed, each yarn separation comb 32 is moved in sequence along the first direction and fixed. Figure 1 The position shown plays a role in fixing the yarn during the winding process, achieving the purpose of convenient yarn threading and yarn fixing, and at the same time, the use of this device and method also further optimizes the winding effect of the winder 4.

[0052] Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
