Description

Technical Field

[0001] The utility model relates to the technical field of sizing machines, in particular to a carbon fiber sizing machine. Background Art

[0002] A carbon fiber sizing machine is a professional device for sizing carbon fibers. The sizing process is an important link in carbon fiber production. Its purpose is to coat a resin matrix on the surface of carbon fibers. This matrix can not only improve the adhesion between carbon fibers and resin, enhance the overall performance of the composite material, but also provide the necessary fluidity and permeability for the subsequent curing process.

[0003] The drum impregnation method is a method for sizing carbon fibers. It soaks carbon fiber cloth or carbon fiber prepreg in a drum containing resin, so that the resin evenly penetrates between the fibers to form a resin matrix. After the carbon fiber tow is soaked in the resin, there may be resin between adjacent tows, resulting in uneven distribution of resin between tows and easy excess, which will affect the performance of the composite material. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a carbon fiber sizing machine that can clean the resin existing between adjacent tows in view of the problem that there may be resin between adjacent tows after the carbon fiber tow is soaked in the resin mentioned in the background art.

[0005] The technical solution of the utility model: A carbon fiber sizing machine includes a base, a soaking tank fixedly installed on the base, and further includes:

[0006] A uniform distribution mechanism, the uniform distribution mechanism is installed on the base, the uniform distribution mechanism drives the carbon fiber tow to reciprocate in the soaking tank, and drives the carbon fiber tow moved to the outside of the soaking tank to vibrate;

[0007] The uniform distribution mechanism includes a pressure roller slidably installed in the soaking tank, a tension roller slidably installed on the base, and a driving component fixedly installed on the base. The carbon fiber tow passes through the pressure roller and the tension roller, and the driving component drives the pressure roller and the tension roller to move synchronously while ensuring that the pressure roller and the tension roller tension the carbon fiber tow.

[0008] Optionally, first sliders are rotatably installed on both sides of the pressure roller, sliding grooves are arranged on both sides inside the soaking tank, and the first sliders are slidably connected with the sliding grooves.

[0009] Optionally, support seats are fixedly installed on both sides of the base, slideways are arranged on the support seats, second sliders are rotatably installed on both sides of the tension roller, and the second sliders are slidably connected with the slideways.

[0010] Optionally, the driving mechanism includes a motor seat fixedly mounted on the base, a motor fixedly mounted on the motor seat, a transmission shaft fixedly mounted on the motor output shaft, a first eccentric wheel and a second eccentric wheel fixedly mounted on the transmission shaft, a first connecting rod rotatably mounted on the first eccentric wheel, and a second connecting rod rotatably mounted on the second eccentric wheel, wherein the first connecting rod is rotatably connected to one of the first sliders, and the second connecting rod is rotatably connected to one of the second sliders.

[0011] Optionally, two first roller seats are fixedly installed on one side of the base, and a first supporting roller is rotatably installed between the two first roller seats.

[0012] Optionally, two second roller seats are fixedly installed on one side of the base, and a second supporting roller is rotatably installed between the two second roller seats.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] The carbon fiber tow is always in a tensioned state through the uniform distribution mechanism, and drives the carbon fiber tow in the immersion box to move back and forth. When the carbon fiber tow in the immersion box moves, the contact uniformity between the carbon fiber tow and the resin will be increased, which can increase the fluidity of the resin in disguise and prevent the problem of uneven resin distribution caused by poor resin fluidity.

[0015] Furthermore, the carbon fiber tows leaving the soaking box can be moved synchronously, and the reciprocating movement of the carbon fiber tows after leaving the resin can throw out the excess resin between adjacent tows, thereby preventing excessive resin and making the resin evenly distributed.

Specific implementation method

[0020] The following is a further description of the technical solution of the utility model in conjunction with the accompanying drawings and specific embodiments.

[0021] Example

[0022] If Figures 1 - 3 As shown, a carbon fiber sizing machine proposed by the utility model includes a base 1, a soaking box 2 fixedly mounted on the base 1, and resin is poured into the soaking box 2. Two first roller seats 6 are fixedly mounted on one side of the base 1, and a first support roller 601 is rotatably mounted between the two first roller seats 6. Two second roller seats 7 are fixedly mounted on one side of the base 1, and a second support roller 701 is rotatably mounted between the two second roller seats 7. The carbon fiber tow 8 is placed on the first support roller 601 and the second support roller 701 respectively, and the carbon fiber tow 8 located in the middle part of the first support roller 601 and the second support roller 701 will contact with the resin inside the soaking box 2, so that a layer of resin matrix can be coated on the carbon fiber tow 8. Under the action of the driving device, the carbon fiber tow 8 is gradually moved, and finally the complete coating of the carbon fiber tow 8 is completed (the driving device for pulling the carbon fiber tow 8 to move is the prior art and will not be repeated again).

[0023] It also includes a uniform distribution mechanism, which is installed on the base 1. The uniform distribution mechanism drives the carbon fiber tows 8 to reciprocate in the immersion box 2, and drives the carbon fiber tows moved to the outside of the immersion box 2 to vibrate. When the carbon fiber tows 8 are tensioned, the carbon fiber tows 8 located in the immersion box 2 can move synchronously when they reciprocate, and the carbon fiber tows 8 located in the immersion box 2 will increase the uniformity of contact between the carbon fiber tows 8 and the resin when they move, which can increase the fluidity of the resin in disguise and prevent the problem of uneven resin distribution caused by poor resin fluidity. The reciprocating movement of the carbon fiber tows 8 after leaving the resin can throw out the excess resin between adjacent tows, thereby preventing excessive resin and making the resin evenly distributed.

[0024] The uniform distribution mechanism includes a pressure roller 3 slidably installed in the soaking tank 2. First sliders 301 are rotatably installed on both sides of the pressure roller 3. Chute grooves are provided on both sides inside the soaking tank 2, and the first sliders 301 are slidably connected to the chute grooves. A tensioning roller 4 is slidably installed on the base 1. Support seats 401 are fixedly installed on both sides of the base 1. Slideways 402 are provided on the support seats 401. Second sliders 403 are rotatably installed on both sides of the tensioning roller 4, and the second sliders 403 are slidably connected to the slideways 402. The carbon fiber tow 8 passes through the pressure roller 3 and the tensioning roller 4. When the tensioning roller 4 moves towards the direction close to the carbon fiber tow 8, that is, when the carbon fiber tow 8 is pressed, the pressure roller 3 moves upward. On the contrary, when the tensioning roller 4 moves away from the carbon fiber tow 8, the pressure roller 3 moves downward. Through the synchronous movement of the tensioning roller 4 and the pressure roller 3, the carbon fiber tow 8 is always kept in a tensioned state, and the carbon fiber tow 8 is driven to swing, so that the carbon fiber tow 8 moves in the soaking tank 2, and the reciprocating movement of the carbon fiber tow 8 after leaving the resin is achieved.

[0025] A driving assembly fixedly installed on the base 1 drives the pressure roller 3 and the tensioning roller to move synchronously while ensuring that the pressure roller 3 and the tensioning roller 4 tension the carbon fiber tow 8. The driving mechanism includes a motor base 5 fixedly installed on the base 1, a motor 501 fixedly installed on the motor base 5, a transmission shaft 502 fixedly installed on the output shaft of the motor 501, a first eccentric wheel 503 and a second eccentric wheel 504 fixedly installed on the transmission shaft 502, a first connecting rod 505 rotatably installed on the first eccentric wheel 503, and a second connecting rod 506 rotatably installed on the second eccentric wheel 504. The first connecting rod 505 is rotatably connected to one of the first sliders 301, and the second connecting rod 506 is rotatably connected to one of the second sliders 403. By driving the transmission shaft 502 to rotate through the motor 501, the first eccentric wheel 503 and the second eccentric wheel 504 rotate synchronously, so that the first connecting rod 505 and the second connecting rod 506 rotate synchronously. Through the transmission of the first connecting rod 505 and the second connecting rod 506, the pressure roller 3 can slide up and down along the chute groove inside the soaking tank 2, and the tensioning roller 4 can slide along the slideway 402. When the tensioning roller 4 moves towards the direction close to the carbon fiber tow 8, the pressure roller 3 will move upward. When the tensioning roller 4 moves to the limit position towards the direction close to the carbon fiber tow 8, the pressure roller 3 also moves to the limit position upward at the same time, and then the pressure roller 3 moves downward. When the tensioning roller 4 moves away from the carbon fiber tow 8, the carbon fiber tow 8 is always kept in a tensioned state, which can effectively make the carbon fiber tow 8 move, make the coating of the carbon fiber tow 8 more uniform, and throw out the excess resin between adjacent tows, thereby preventing excessive resin.

[0026] Working principle: The carbon fiber tow 8 passes through the pressure roller 3 and the tension roller 4. The drive shaft 502 is rotated by the motor 501, so that the first eccentric wheel 503 and the second eccentric wheel 504 rotate synchronously, which enables the first connecting rod 505 and the second connecting rod 506 to rotate synchronously. Then, the pressure roller 3 slides up and down along the chute inside the soaking tank 2, and the tension roller 4 slides along the slideway 402. When the tension roller 4 moves towards the carbon fiber tow 8, the pressure roller 3 will move upwards. When the tension roller 4 moves to the extreme position towards the carbon fiber tow 8, the pressure roller 3 also moves to the extreme position upwards, and then the pressure roller 3 moves downwards. When the tension roller 4 moves away from the carbon fiber tow 8, the carbon fiber tow 8 is always kept in a tensioned state, which can effectively move the carbon fiber tow 8, make the coating on the carbon fiber tow 8 more uniform, and fling out the excess resin between adjacent tows, thereby preventing excessive resin.

[0027] The above specific embodiments are only several optional embodiments of the present invention.
