[0029] Embodiment:

[0030] As shown in the Figure 1 to Figure 5 accompanying drawings:

[0031] The present utility model provides a pay-off device for a new type of carbon fiber prepreg, which includes a base 1. On both sides of the top of the base 1, a pair of mounting plates 2 are symmetrically installed. Between the pair of mounting plates 2, a rotating shaft 3 is installed. On the circumferential side of the rotating shaft 3, a number of connecting frames 4 are installed. At both ends of the number of connecting frames 4, a pair of first mounting seats 5 are symmetrically installed. On one side of the first mounting seat 5, a first sliding groove 6 is installed. At both ends of the first sliding groove 6, a pair of first sliding blocks 7 are symmetrically installed. On one side of the first sliding block 7, a second sliding groove 8 is provided. At both ends of the second sliding groove 8, a pair of second sliding blocks 9 are symmetrically installed. On one side of the pair of second sliding blocks 9, a pair of arc-shaped clamping plates 10 are symmetrically installed. On one side of the pair of mounting plates 2, a driving assembly is installed.

[0032] One side of one of the pair of mounting plates 2 is provided with a chassis 11. Inside the chassis 11, a worm gear 12 is installed, and the worm gear 12 is connected to a rotating shaft 3. At the bottom end inside the chassis 11, a worm 13 is installed, and the worm 13 is meshed with the worm gear 12. On one side of the bottom end inside the chassis 11, a first motor 14 is installed, and the output end of the first motor 14 is in transmission connection with the worm 13 through a coupling. The first motor 14 drives the worm 13 to rotate. Since the worm gear 12 is meshed with the worm 13, the worm gear 12 rotates together, thereby driving the rotating shaft 3 to rotate. The rotating shaft 3 drives a pair of first mounting seats 5 to rotate through a connecting frame 4. When the carbon fiber prepreg on one first mounting seat 5 is used up, the other first mounting seat 5 can quickly rotate to the position between a pair of driving discs 23, so that the unwinding device can quickly continue to be put into use.

[0033] Wherein, a first double-headed screw 15 is rotatably installed in a first chute 6, and the first double-headed screw 15 penetrates through the front and rear sides of a pair of first sliding blocks 7 and is threadedly connected to the pair of first sliding blocks 7. By rotating the first double-headed screw 15, under the limiting action of the first chute 6, the pair of first sliding blocks 7 move towards or away from each other simultaneously, so as to adapt to the lengths of carbon fiber prepreg rollers of different sizes.

[0034] Wherein, a second motor 16 is installed on one side of the first mounting seat 5, and the output end of the second motor 16 is in transmission connection with the first double-headed screw 15 through a coupling. The second motor 16 drives the first double-headed screw 15 to rotate, thereby driving the pair of first sliding blocks 7 to move.

[0035] Wherein, a second double-headed screw 17 is rotatably installed in a second chute 8, and the second double-headed screw 17 penetrates through the upper and lower ends of a pair of second sliding blocks 9 and is threadedly connected to the pair of second sliding blocks 9. By rotating the second double-headed screw 17, under the limiting action of the second chute 8, the pair of second sliding blocks 9 move towards or away from each other simultaneously, driving a pair of arc-shaped clamping plates 10 to move, and clamping or loosening the carbon fiber prepreg roller.

[0036] Wherein, a third motor 18 is installed at the top end of the first sliding block 7, and the output end of the third motor 18 is in transmission connection with the second double-headed screw 17 through a coupling. The third motor 18 drives the second double-headed screw 17 to rotate, thereby driving the pair of second sliding blocks 9 to move.

[0037] Among them, the driving assembly includes a second mounting seat 19, the second mounting seat 19 is installed on one side of a pair of mounting plates 2, and a third slide groove 20 is provided at the top of the second mounting seat 19, and a pair of third sliders 21 are symmetrically installed at both ends of the third slide groove 20, and a connecting plate 22 is installed on the top of the pair of third sliders 21, and a pair of connecting plates 22 are installed with a driving disk 23 on the opposite side, and a third bidirectional screw 24 is installed for rotation inside the third slide groove 20, and the third bidirectional screw 24 passes through the left and right sides of the pair of third sliders 21 and is threadedly connected to the pair of third sliders 21. Through the rotation of the third bidirectional screw 24, under the limiting action of the third slide groove 20, the pair of third sliders 21 move toward each other at the same time, so that the driving disk 23 can clamp the roll of carbon fiber prepreg, thereby controlling the rotation of the roll, wherein the size of the driving disk 23 matches the size of the roll of carbon fiber prepreg.

[0038] Among them, a fourth motor 25 is installed on one side of the second mounting seat 19, and the output end of the fourth motor 25 is connected to the third bidirectional screw 24 through a coupling. The fourth motor 25 drives the third bidirectional screw 24 to rotate, and then drives a pair of third sliders 21 to move toward or away from each other at the same time.

[0039] A fifth motor 26 is installed on one side of one of the pair of connecting plates 22 , and an output end of the fifth motor 26 is transmission-connected to the driving disc 23 via a coupling, so that the fifth motor 26 drives the driving disc 23 to rotate.

[0040] A controller 27 is installed on one side of one of the pair of mounting plates 2 , and the controller 27 is electrically connected to the first motor 14 , the second motor 16 , the third motor 18 , the fourth motor 25 and the fifth motor 26 .

[0041] Working principle of this embodiment: When using this unwinding device for new carbon fiber prepreg, the staff first place the carbon fiber prepreg roll on one side of a first mounting seat 5, and turn on the second motor 16. The second motor 16 drives the first bidirectional screw 15 to rotate. Under the limiting action of the first chute 6, a pair of first sliders 7 move towards or away from each other simultaneously to a position close to both ends of the roll. Then, turn on the third motor 18. The third motor 18 drives the second bidirectional screw 17 to rotate. Under the limiting action of the second chute 8, a pair of second sliders 9 move towards each other simultaneously, driving a pair of arc-shaped clamping plates 10 to move and clamp the roll. After clamping is completed, the staff turn on the first motor 14. The first motor 14 drives the worm 13 to rotate. Since the worm 13 is meshed with the worm gear 12, the worm gear 12 rotates together at this time, driving the connecting frame 4 to rotate, and then driving the clamped roll to rotate to the side close to the driving component through the first mounting seat 5. At this time, the staff turn on the fourth motor 25. The fourth motor 25 drives the third bidirectional screw 24 to rotate. Under the limiting action of the third chute 20, a pair of third sliders 21 move towards each other simultaneously, enabling the driving disc 23 to clamp the roll. Then, the staff turn on the third motor 18 to make a pair of arc-shaped clamping plates 10 move away from each other and loosen the roll. At this time, the staff guide the carbon fiber prepreg into the subsequent processing machinery and turn on the fifth motor 26 to process the carbon fiber prepreg. During the processing, the staff install a new roll on one side of another first mounting seat 5. When the previous roll is used up, the new roll can quickly rotate to the position close to the driving component following the first mounting seat 5 and wait for processing, improving the working efficiency during processing.
