Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon fiber yarn cans, in particular to a carbon fiber yarn can and a preparation process thereof. BACKGROUND

[0002] Traditional double twister usually consists of rotating parts such as spindles, spindles and yarn storage discs, and non-rotating parts such as yarn cans and hollow spindles. The yarn can usually has a cylindrical main body, the inside of which is provided with a space for loading yarn. One end of the yarn can is usually provided with an opening for the entry and exit of yarn. In addition, the surface of the yarn can is also subjected to special treatment, such as oxidation treatment, polishing, etc., to improve its wear resistance and smoothness. The yarn storage disc and the yarn can are usually made of metal material. Although these traditional yarn cans have certain strength and durability, they also have some obvious limitations. For example, metal yarn cans are usually heavy, which is not conducive to the lightweight of the equipment. At the same time, the metal material has poor corrosion resistance to chemicals such as acid, alkali and salt, and is easily corroded during use, which affects the service life. In addition, the yarn can and the yarn storage disc in the double twister have some inconveniences during use.

[0003] The prior art CN211311709U discloses a double twister spindle applicable to light yarn, which comprises a rack, a spindle rotatingly arranged on the rack, a middle part of the spindle having a yarn inlet channel communicating with a top surface of the spindle and a side surface of a lower end of the spindle, a twisting disc fixedly sleeved on a lower part of the spindle, the twisting disc being provided with a yarn outlet channel communicating with an inner side wall and an outer side wall of the twisting disc, the yarn outlet channel being in communication with the yarn inlet channel, a yarn can fixedly arranged on the rack, a bottom surface of the yarn can having a through hole, an upper end of the spindle being arranged inside the yarn can through the through hole, and a yarn separating disc sleeved on the spindle and located between the yarn can and the twisting disc, the yarn separating disc being fixedly connected with the twisting disc and / or the spindle, the diameter of the yarn separating disc being greater than the diameter of the yarn can by 10mm-50mm. The double twister spindle can prevent the light yarn from rubbing against the yarn can due to the fact that the yarn loop cannot be completely opened during twisting, and can avoid the phenomenon of yarn fluffing, thereby improving the yield of yarn twisting. However, the diameter of the yarn separating disc is enlarged to enlarge the range of the yarn loop, but the yarn still rubs against the yarn separating disc when moving, and the nature of sliding friction is not changed. When the yarn has a certain tension, the unwinding resistance is relatively large, which affects the unwinding speed of the yarn, finally reduces the twisting effect, and affects the product quality.

[0004] Secondly, the non-rotating parts such as the yarn can are sleeved outside the rotating parts such as the spindles, the spindles and the yarn storage discs, and are connected by rolling bearings. The spindles are driven by a belt or a spindle belt to rotate together with the yarn storage discs. However, the rotating parts will affect the non-rotating parts during rotation, resulting in unstable yarn tension, increased breakage rate and other problems.

[0031] Embodiment two A carbon fiber yarn tank preparation process, comprising the following steps: Step one: selecting a suitable mold material, designing the mold according to the shape and size of the product, and preheating the mold in a hot press tank to remove moisture in the mold and preheat the mold; Step two: processing carbon fiber and matrix materials such as epoxy resin into carbon fiber prepreg through film coating, hot pressing, cooling and other processes, cutting and laying the prepreg on the mold according to specific layering requirements, and paying attention to compacting and removing interlayer gas inclusions; Step three: using a vacuum film, air-permeable felt and sealing tape material to package the laid prepreg blank in a vacuum bag, and performing vacuum treatment on the vacuum bag, with the total time controlled within 5-15 minutes; Step four: connect the encapsulated vacuum bag to the vacuum pump and push it into the autoclave, the working pressure of the autoclave is usually less than 1.6 MPa, the curing temperature varies according to the different materials used, but the commonly used upper limit temperature is 250℃.

[0033] The following is the entire working process and working principle of the above embodiment: First, place the inner permanent magnet 24 and the outer permanent magnet 25 at the corresponding positions inside and outside the carbon fiber yarn tank 1, ensure that the polarities of the inner permanent magnet 24 and the outer permanent magnet 25 are alternately arranged, if the magnet in a certain area inside the carbon fiber yarn tank 1 is N pole, then the magnet at the corresponding position outside should be S pole, and vice versa, through the principle of "opposites attract, like poles repel", it helps to improve the braking effect of the two-for-one twister, by setting the inner permanent magnet 24 and the outer permanent magnet 25 with relative symmetry inside the carbon fiber yarn tank 1, the inner permanent magnet 24 can evenly force the spindle 3, so that the carbon fiber yarn tank 1 and other stationary parts are stably braked during the rotation of the two-for-one twister, and are not affected by the rotating part, so that even if the two-for-one twister increases the speed of the rotating part, the yarn 6 in the two-for-one twister will not break or have few broken ends, and then the outer retaining ring 22 and the inner retaining ring 23 are embedded in the embedding groove formed on the outer circumferential surface of the outer retaining ring 22 and the inner retaining ring 23, the inner permanent magnet 24 and the outer permanent magnet 25 are embedded in the embedding groove, the precise design of the embedding groove allows the permanent magnets to be arranged in a specific way, which helps to optimize the distribution of the magnetic field, and the permanent magnets embedded in the specially designed embedding groove can effectively fix the position of the permanent magnets and prevent them from moving or falling off during operation.

[0034] The yarn 6 moves inside the wire slot 75, and the first roller 76 and the second roller 77 are arranged at the force receiving and friction points of the yarn 6 inside the wire slot 75.

The device changes the sliding friction into rolling friction by using the first roller 76 and the second roller 77, greatly reduces the unwinding resistance, and makes the unwinding smooth, thereby ensuring the twisting quality. At the same time, the spindle 3 rotates the yarn storage disc 4 in the rotating process, the yarn storage disc 4 rotates the auxiliary gear 74, the auxiliary gear 74 slides inside the auxiliary sliding groove 26, and when the auxiliary gear 74 is engaged with the incomplete gear 27, the incomplete gear 27 makes the auxiliary gear 74 rotate, the auxiliary gear 74 rotates the first cylinder 71, the first cylinder 71 rotates the second cylinder 72, and the second cylinder 72 makes the limiting plate 73 slide in the square groove. Through the cooperation of the incomplete gear 27 and the auxiliary gear 74, the auxiliary gear 74 moves the second cylinder 72 in the process of engaging and rolling on the incomplete gear 27. The movement of the second cylinder 72 can increase the length of the yarn 6 inside the wire slot 75, thereby adjusting the tension of the yarn 6 in the unwinding process. In the case of gradually reducing the use of the yarn 6, the movement of the yarn storage disc 4 can ensure that the yarn 6 always maintains appropriate tension, avoids the problems of yarn breakage or uneven twist caused by excessive or insufficient tension, and guides the yarn 6 to unwind according to a more optimized path, which helps to reduce the twisting and knotting of the yarn 6 and improve the quality and production efficiency of the yarn 6.
