[0005] Therefore, we propose a carbon fiber spreading device to solve this problem. Utility Model Content

[0006] The purpose of this invention is to provide a yarn spreading device for carbon fiber to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A carbon fiber yarn spreading device includes: a base plate, two right side plates fixedly connected to the top of the base plate, each of the two right side plates having a right spreading roller rotatably connected to its adjacent side; two left side plates slidably connected to the top of the base plate, each of the two left side plates having a left spreading roller movably installed on its adjacent side; a housing fixedly connected to the top of the base plate; a concave plate fixedly connected to the bottom of the inner wall of the housing; a rectangular plate slidably connected inside the concave plate; and a tension plate fixedly connected to the top of the rectangular plate.

[0009] Preferably, the base plate has a second built-in groove inside, a partition is fixedly connected inside the second built-in groove, a second motor is fixedly connected to the top of the partition, a lead screw is fixedly connected to the output end of the second motor, and the rectangular plate is threaded onto the outside of the lead screw.

[0010] Preferably, a first built-in groove is provided inside the left side of the base plate, and a bidirectional threaded rod is rotatably connected inside the first built-in groove. A convex plate is fixedly connected to the bottom of each of the two left side plates, and the two convex plates are threaded onto the outside of the same bidirectional threaded rod. A first motor is fixedly connected to the front side of the base plate, and the output end of the first motor is fixedly connected to the front end of the bidirectional threaded rod.

[0011] Preferably, a groove is provided on the front side of the left roller, and a mounting column is fixedly connected to the front side of the left side plate located on the front side. An arc-shaped plate is fixedly connected to the front end of the mounting column, and a third motor is fixedly connected to the rear side of the arc-shaped plate. A square plate is fixedly connected to the output end of the third motor, and the square plate movably abuts against the inside of the groove.

[0012] Preferably, an extension plate is fixedly connected to the right side of each of the two convex plates, a guide post is fixedly connected inside the first built-in groove, and the two extension plates are slidably connected to the outside of the same guide post.

[0014] Preferably, the same through groove is provided on both sides of the outer casing.

[0015] In this utility model, a carbon fiber spreading device is described. The spreading yarn outside the right spreading roller passes through the right through groove and through the inside of the tension plate, and finally passes through the left through groove and wraps around the outside of the left spreading roller. The second motor is then started to drive the lead screw to rotate, which causes the rectangular plate to move downward, thereby driving the tension plate to move downward and adjusting the spreading yarn tension. The power supply is then started to heat the spreading yarn inside the shell, which softens the sizing agent on the surface of the spreading yarn and weakens the bonding force between the fibers, so as to spread it better.

[0016] In this utility model, a carbon fiber yarn spreading device is described. By starting a third motor to drive a square plate to rotate, the left spreading roller will rotate to wind the yarn. Then, the first motor will start to drive a bidirectional threaded rod to rotate, causing the two convex plates on both sides to move away from each other, the square plate will release its contact with the groove, and the left spreading roller will fall off.

[0017] This utility model has a reasonable structural design. The automatic unloading function of the left spreading roller is realized through the cooperation of the convex plate, the bidirectional threaded rod, the left side plate, the square plate and the groove, which improves the application range of the device. The tension adjustment function of the spreading yarn is realized through the cooperation of the partition plate, the second motor, the lead screw, the rectangular plate and the tension plate, which improves the working efficiency of the device.
