The preformed hole 18 will gather the carbon fiber bundle before solidification to achieve preforming of the carbon fiber bundle. When the carbon fiber bundle passes through the preformed hole 18, residual glue will be left on the preformed hole 18. When the preformed plate 16 needs to be replaced, the clamping plate 14 can be pressed to compress the first spring 15. At this time, the angle at the bottom of a pair of clamping plates 14 will expand and disengage from the tooth plate 17, so that the preformed plate 16 loses the friction between the tooth plate 17 and the clamping plate 14 and is in an active state. At this time, the staff can disassemble and replace the preformed plate 16; pressing the clamping plate 14 can make the tooth plate 17 disengage from the clamping plate 14 and make the preformed plate 16 active, so as to achieve rapid disassembly of the preformed plate 16 by the equipment, reduce the cumbersomeness of the replacement operation of the preformed plate 16, and improve the convenience of the equipment for replacing the preformed plate 16.

[0027] Reference Figures 2 to 4As shown, the inner side wall of the frame 12 is symmetrically provided with a first slide groove 2; a pair of sliders 22 are fixedly connected to the middle of the preformed plate 16; a second slide groove 25 is provided in the middle of the first slide groove 2; a damping spring 23 is fixedly connected to the inner side wall of the first slide groove 2; a top plate 24 is fixedly connected to the top of the damping spring 23; when the staff presses the clamping plate 14 to make the preformed plate 16 and the tooth plate 17 separate from the clamping plate 14, the preformed plate 16 will slide along the first slide groove 2 with the slider 22, and the slider 22 will contact and hit the top plate 24 when moving, and the top plate 24 will be pressed. The impact will be transmitted to the damping spring 23, and the damping spring 23 will be compressed under the pressure and absorb the impact, and then the damping spring 23 will transmit the attenuated impact force to the frame 12.

The second magnet 32 ​​will be affected by the repulsive force of the first magnet 3, so that the slider 22 will also be affected by the repulsive force, thereby reducing the sliding speed of the slider 22, and further reducing the impact of the slider 22 on the frame 12 when it moves.

[0029] Reference Figure 4 As shown, the inner side wall of the second slide groove 25 is symmetrically hinged with multiple first baffles 4; the first baffle 4 and the second slide groove 25 are connected by a torsion spring; during normal operation, the first baffle 4 will close the second slide groove 25, so that the slider 22 will not slide out of the second slide groove 25 when sliding along the first slide groove 2, and when the staff slides the slider 22 out along the second slide groove 25, the slider 22 will squeeze the first baffle 4, so that the angle of the first baffle 4 will change and the torsion spring will bend, and then the slider 22 will slide along the surface of the first baffle 4 until the slider 22 and the preformed plate 16 are disassembled.

[0030] Reference Figure 4As shown, a plurality of rotating wheels 5 are rotatably connected to the middle part of the first baffle plate 4; the rotating wheels 5 are located inside the second slide groove 25; when the slider 22 slides along the first baffle plate 4, the slider 22 will also come into contact with the rotating wheels 5, and the rotating wheels 5 will rotate under the action of friction, so that the sliding friction between the slider 22 and the first baffle plate 4 is converted into rolling friction, thereby reducing the friction generated when the slider 22 slides along the first baffle plate 4.

[0031] Reference Figure 3 and Figure 5 As shown, a pick plate 6 is fixedly connected to the middle of the preformed plate 16; a plurality of second springs 62 are fixedly connected to the top of the pick plate 6; a fixing plate 63 is fixedly connected to the top of the second spring 62; a plurality of fixing holes 64 are opened in the middle of the fixing plate 63; the fixing holes 64 and the preformed holes 18 are arranged correspondingly; the carbon fiber harness will pass through the fixing plate 63 and the fixing holes 64 before passing through the preformed holes 18, and when the carbon fiber harness becomes loose during movement, the fixing plate 63 will support the carbon fiber harness under the elastic force of the second spring 62, thereby increasing the tension of the carbon fiber harness during movement, so that the surface of the carbon fiber harness is in a taut state.

[0032] Reference Figure 5 As shown, a pair of second baffles 7 are fixedly connected to the middle of the fixing plate 63; the second baffles 7 are symmetrically arranged and have an arc-shaped structure; when the carbon fiber harness passes through the fixing hole 64, the residual glue on the surface will splash, and the splashed residual glue will reach the surface of the second baffle 7 and be intercepted by the second baffle 7, thereby reducing the secondary pollution to the carbon fiber harness caused by the splashing of the residual glue.

[0033] Reference Figure 5 As shown, a plurality of bristles 8 are fixedly connected to the inner wall of the second baffle 7; the bristles 8 are arranged in an array; when the carbon fiber harness moves along the fixing hole 64, it will come into contact with the bristles 8, and the bristles 8 will clean the surface of the carbon fiber harness and reduce the residual glue remaining on the surface of the carbon fiber harness.

[0034] Working principle: The carbon fiber harness will pass through the preformed holes 18 from the multiple preformed plates 16. The preformed holes 18 will gather the carbon fiber harness before solidification to achieve preforming of the carbon fiber harness. When the carbon fiber harness passes through the preformed holes 18, residual glue will be left on the preformed holes 18. When the preformed plate 16 needs to be replaced, the clamping plate 14 can be pressed to make the first spring 15 in a compressed state. At this time, the angle between the bottom of a pair of clamping plates 14 will expand and disengage from the tooth plate 17, so that the preformed plate 16 loses the friction between the tooth plate 17 and the clamping plate 14 and is in an active state. At this time, the staff can disassemble and replace the preformed plate 16; when the staff presses After the clamping plate 14 is pressed to make the preformed plate 16 and the toothed plate 17 detach from the clamping plate 14, the preformed plate 16 will slide along the first slide groove 2 with the slider 22. When the slider 22 moves, it will contact and hit the top plate 24. The top plate 24 will transmit the impact to the damping spring 23. The damping spring 23 will be compressed under the pressure and absorb the impact. Then the damping spring 23 will transmit the attenuated impact force to the frame 12. Finally, the staff can slide the slider 22 through the second slide groove 25 to connect the preformed plate 16 and realize the disassembly of the preformed plate 16. When the slider 22 moves along the first slide groove 2, it will bring the second magnetic When the slider 22 moves along the second slide groove 25, the slider 22 will squeeze the first baffle plate 4, so that the angle of the first baffle plate 4 will change and the torsion spring will be bent, and then the slider 22 will slide along the surface of the first baffle plate 4 until the slider 22 and the preformed plate 16 are disassembled; when the slider 22 slides along the first baffle plate 4, the slider 22 will also come into contact with the rotating wheel 5, and the rotating wheel 5 will rotate under the action of friction. The movement converts the sliding friction between the slider 22 and the first baffle 4 into rolling friction; the carbon fiber harness passes through the fixing plate 63 and the fixing hole 64 before passing through the preformed hole 18. When the carbon fiber harness relaxes during movement, the fixing plate 63 supports the carbon fiber harness under the elastic force of the second spring 62, thereby increasing the tension of the carbon fiber harness during movement; when the carbon fiber harness passes through the fixing hole 64, the residual glue on the surface will splash, and the splashed residual glue will reach the surface of the second baffle 7 and be intercepted by the second baffle 7; when the carbon fiber harness moves along the fixing hole 64, it will come into contact with the bristles 8, and the bristles 8 will clean the surface of the carbon fiber harness.
