[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example 1: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a high-efficiency thermoplastic carbon fiber composite material preparation device, including a limiting mounting frame 1, a material winding roller 2, a guide mounting seat 3, a transmission structure, a position fixing ring 4, a sliding limiting block 5, and a reset elastic element 6. The limiting mounting frame 1 has U-shaped grooves on both the upper and lower sides of its front. Two material winding rollers 2 are provided, each placed inside the U-shaped grooves on the upper and lower sides of the limiting mounting frame 1. Four guide mounting seats 3 are provided, evenly distributed and bolted to the left and right sides of the limiting mounting frame 1. The transmission structure is located on the front side of the limiting mounting frame 1. Four position fixing rings 4 are provided, rotatably connected to the left and right sides of the two material winding rollers 2 respectively. Each position fixing ring 4 has a limiting groove on both its front and rear sides. A sliding limiting block 5 is slidably connected to the front and rear sides of each guide mounting seat 3. Each sliding limiting block 5 is elastically connected to the guide mounting seat 3 through a reset elastic element 6.

[0021] The transmission structure includes a reciprocating self-locking drive component 101 and a first friction disc 102. Four reciprocating self-locking drive components 101 are provided, and the four reciprocating self-locking drive components 101 are evenly distributed and bolted to the left and right sides of the limiting mounting frame 1. Four first friction discs 102 are provided, and the four first friction discs 102 are evenly distributed and rotatably connected to the left and right sides of the limiting mounting frame 1. The four first friction discs 102 are coaxially fixedly connected to the output shafts of the four reciprocating self-locking drive components 101 respectively.

[0022] The transmission structure also includes a second friction disc 103 and a third friction disc 201. There are four second friction discs 103, which are evenly distributed and rotatably connected to the left and right sides of the limiting mounting frame 1. There are four third friction discs 201, which are respectively fixedly connected to the left and right sides of the two material winding rollers 2.

[0023] The transmission structure also includes a transmission gear 301 and a transmission rack 501; four transmission gears 301 are provided, and the four transmission gears 301 are rotatably connected to the lower part of the four guide mounting seats 3 respectively; a transmission rack 501 is fixedly connected to the lower part of each sliding limit block 5, and the transmission rack 501 meshes with the transmission gear 301.

[0024] The specific usage and function of this embodiment are as follows: When slitting and rewinding thermoplastic carbon fiber composite materials, the reciprocating self-locking drive 101 drives the first friction disk 102. When the first friction disk 102 rotates, it pushes the second friction disk 103 to rotate through friction. When the second friction disk 103 rotates, it pushes the third friction disk 201 and the material winding roller 2 to rotate through friction. The material winding roller 2 winds up the slid material. When the material winding roller 2 needs to be replaced after winding, a sliding limit block 5 is pushed outward first, so that the sliding limit block 5 drives the transmission rack 501 to slide along the guide mounting seat 3. When the transmission rack 501 slides, it will push the transmission gear 301 to rotate. When the transmission gear 301 rotates, it will push another transmission rack 501 and the sliding limit block 5 to slide to the other side. At this time, the sliding limit block 5 will move out of the limiting groove of the position fixing ring 4 and cancel the positioning of the material winding roller 2. After the material winding roller 2 is replaced, the sliding limit block 5 is released, and the reset elastic member 6 will push the sliding limit block 5 to reset.

[0025] Example 2: As attached Figure 3 To be continued Figure 5 As shown: Based on Embodiment 1, a limiting structure is also included; the limiting structure is disposed on the front side of the limiting mounting bracket 1.

[0026] The limiting structure includes position limiting baffles 104 and limiting support frames 105; four position limiting baffles 104 are provided, and the four position limiting baffles 104 are evenly distributed and fixedly connected to the left and right sides of the limiting mounting frame 1; four limiting support frames 105 are provided, and the four limiting support frames 105 are evenly distributed and rotatably connected to the left and right sides of the limiting mounting frame 1.

[0027] The limiting structure also includes tension springs 106, first positioning shafts 107, and second positioning shafts 108. Four first positioning shafts 107 are provided, and the four first positioning shafts 107 are respectively fixedly connected to the upper part of four limiting support frames 105. Four second positioning shafts 108 are provided, and the four second positioning shafts 108 are respectively fixedly connected to the left and right sides of the limiting mounting frame 1. Four tension springs 106 are provided, the upper parts of the four tension springs 106 are respectively rotatably connected to the outside of the four second positioning shafts 108, and the lower parts of the four tension springs 106 are respectively rotatably connected to the outside of the four first positioning shafts 107.

[0028] The specific usage and function of this embodiment are as follows: After the sliding limit block 5 moves out of the limiting groove of the position fixing ring 4, the tension spring 106 will pull the limiting support frame 105 to swing upward, causing the limiting support frame 105 to push the material winding roller 2 upward, so that the material winding roller 2 moves to the upper part of the U-shaped groove, making it convenient to remove the material winding roller 2. When installing a new material winding roller 2, simply place the material winding roller 2 on the upper part of the limiting support frame 105, align the position fixing ring 4 with the guide mounting seat 3, and then press the material winding roller 2 downward until the limiting rings on both sides of the position fixing ring 4 are closed. When the groove is aligned with the sliding limit block 5, the reset elastic element 6 will push the sliding limit block 5 to reset, so that the sliding limit block 5 is inserted into the limiting groove of the position fixing ring 4 to position the new material take-up roller 2. When the material take-up roller 2 is pressed down, the limit support frame 105 will be under pressure and pull the tension spring 106 and swing downward. The position limiting baffle 104 can limit the swing angle of the limit support frame 105 to prevent the tension spring 106 from having a dead point position. The first positioning shaft 107 and the second positioning shaft 108 can limit the position of the tension spring 106.
