[0002] Carbon fiber cloth is also known as carbon fiber cloth, carbon fiber cloth, carbon fiber woven cloth, carbon fiber prepreg cloth, carbon fiber reinforcement cloth, carbon fiber fabric, carbon fiber tape, carbon fiber sheet (prepreg cloth), etc. Carbon fiber reinforcement cloth is a unidirectional carbon fiber reinforcement product, typically woven from 12K carbon fiber yarn. The cutting process of carbon fiber cloth produces a large amount of debris, which needs to be collected to prevent it from being inhaled and endangering human health.

[0003] For example, the Chinese utility model patent with the announcement number CN214520614U discloses a carbon fiber cloth processing and cutting device, whose technical solution is as follows: it includes a workbench; a control switch is fixedly installed in the middle of the lower end of the workbench, a cutting mechanism is provided in the middle of the inner cavity of the workbench, a winch is welded to the right end of the workbench, a pull rope is wound around the output end of the winch, a guide wheel is fixedly installed at the upper right end of the workbench, and a brush is provided at the upper end of the workbench; a bracket is provided on the left side of the workbench, a collection box is welded to the lower end of the bracket, a box body is welded to the upper end of the bracket, an exhaust fan is provided on the right side of the box body, a straight pipe is connected to the left side of the exhaust fan, the left end of the straight pipe is connected to the right side of the box body, and a curved pipe is connected to the right side of the exhaust fan.

[0004] The applicant has found that in the above technical solution, when cutting the carbon fiber cloth, a motor is used to drive the cutting knife, and the carbon fiber cloth is cut by rotating the cutting knife. This cutting method will cause many burrs to appear on the corners of the carbon fiber cloth, and will also lead to low cutting accuracy, thereby making the qualified rate of the cut carbon fiber cloth low, and increasing the cost of the company to produce carbon fiber cloth.

Two support seats are fixed to the back of the conveying box 1, and a collecting box 2 is fixed to the bottom of the conveying box 1. A plurality of rollers 3 are fixed to the front and back of the inner cavity of the conveying box 1 through bearings. Two positioning plates 4 are also fixed to the front and back of the inner cavity of the conveying box 1. A fixed cutter 5 is fixed between the front and back of the inner cavity of the conveying box 1. A movable cutter 6 is hinged to the back of the conveying box 1 through a hinged frame. A square hole for adjusting the angle of the right end of the movable cutter 6 is opened at the right end of the conveying box 1 and near its top surface.

[0025] The top surface of the collecting box 2 is fixed to the conveying box 1 by bolts. The collecting box 2 is a rectangle with a hollow interior and a missing top surface. The bottom surface of the conveying box 1 is provided with a dust exhaust hole connected to the collecting box 2.

[0026] A conveying assembly is provided on the front of the conveying box 1 , a cutting assembly is provided on the top surface of the conveying box 1 , and a dust removal assembly is provided inside the collecting box 2 .

[0027] By setting up the conveying component, the carbon fiber cloth can be conveyed stably and at a uniform speed, and the length of the carbon fiber cloth that needs to be cut can be effectively controlled.

[0028] By setting up the cutting assembly, burrs can be effectively avoided at the cutting position of the carbon fiber cloth when the carbon fiber cloth is cut, thereby improving the quality of the cut carbon fiber cloth.

[0029] Furthermore, by providing a dust removal component, the debris generated during the cutting of the carbon fiber cloth can be effectively collected, thereby preventing the debris generated during the cutting of the carbon fiber cloth from being inhaled into the mouth and nose of the workers, thereby endangering their health.

[0030] See also Figure 2 In order to convey the carbon fiber cloth, the conveying assembly in this embodiment includes a conveying motor 14 fixed to the front of the conveying box 1. The output shaft of the conveying motor 14 is fixed to the front of the conveying box 1 through a bearing. Two driving wheels 15 are fixed to the output shaft of the conveying motor 14. The outer surfaces of the two driving wheels 15 are both connected to the transmission belt 16. The other end of the transmission belt 16 is connected to the driven wheel 17. A rotating rod 18 is fixed to the back of the driven wheel 17. Two support seats are rotatably connected to the backs of the two rotating rods 18 through bearings respectively. A conveying roller 19 is fixed to the outer surface of the rotating rod 18.

[0031] When the carbon fiber cloth needs to be conveyed, the carbon fiber cloth is first placed between the drum and the conveying roller 19, and then the conveying motor 14 is started. When the output shaft of the conveying motor 14 rotates, the two driving wheels 15 fixed to the outer surface of the conveying motor 14 are driven to rotate. During the rotation of the two driving wheels 15, the two driven wheels 17 are driven to rotate through the transmission belt 16 provided on the outer surface thereof. The two driven wheels 17 respectively drive the two rotating rods 18 to rotate, and the rotating rods 18 drive the conveying rollers 19 to rotate. During the rotation of the conveying rollers 19, the carbon fiber cloth between the conveying rollers 19 and the drum 3 can be conveyed.

[0032] See also Figure 3 In order to cut the carbon fiber cloth, the cutting assembly in this embodiment includes an L-shaped bracket 7 fixed to the front of the collection box 2, a mounting plate 8 is fixed to the left end of the bracket 7, a rotating motor 9 is fixed to the left end of the mounting plate 8, a circular plate 10 is fixed to the output shaft of the rotating motor 9, an eccentric rod 11 is fixed to the right end of the circular plate 10 and located away from the center of the circle, a pull rod 12 is fixed to the outer surface of the eccentric rod 11 through a bearing, and a rotating shaft 13 is fixed to the other end of the pull rod 12 through a bearing, and the left end of the rotating shaft 13 is fixed to the right end of the movable cutter 6.

[0033] When cutting the carbon fiber, first ensure that the carbon fiber cloth is on the top surface of the two positioning plates 4, and further start the rotating motor 9. The output shaft of the rotating motor 9 will drive the circular plate 10 to rotate when it rotates. During the rotation of the circular plate 10, the eccentric rod 11 fixed at the right end of the circular plate 10 will be driven to rotate along with the circular plate 10. During the rotation of the eccentric rod 11, the pull rod 12 fixed to the outer surface of the eccentric rod 11 through the bearing will be driven to move. Since the other end of the pull rod 12 is rotatably connected to the rotating shaft 13 through the bearing, when the eccentric rod 11 moves to the top surface of the right side of the circular plate 10, the front edge of the movable cutter 6 will be driven to deviate upward along the hinged connection with the conveying box 1, and further under the continuous rotation of the rotating motor 9, the pull rod 12 will be driven to move downward again, driving the angle of the movable cutter 6 to return to the cutting state, and the carbon fiber cloth is cut with the cooperation of the movable cutter 6 and the fixed cutter 5.

[0034] See also Figure 4 and Figure 5 In order to collect the debris generated when cutting the carbon fiber cloth, the dust removal assembly in this embodiment includes two inclined plates 20 fixed at both ends of the conveying box 1, the dust removal assembly also includes a filter screen 21 fixed between the left and right side walls of the inner cavity of the collection box 2 and multiple exhaust fans 22 fixed at the right end of the collection box 2.

[0035] When debris is generated during the cutting of the carbon fiber cloth, the plurality of exhaust fans 22 are first started to transmit suction to the collection box 2. Further, the suction enters the collection box 2. At the same time, the debris generated during the cutting of the carbon fiber cloth will fall into the collection box 2 under the action of gravity, and the two inclined plates 20 will drive the debris to slide into the collection box. At the same time, the wind will also drive some fine impurities into the collection box, thereby preventing the impurities generated during the cutting of the carbon fiber cloth from being inhaled into the mouth and nose of the human body.
