[0002] The full name of polyurethane is polyurethane, which is a polymer material with excellent mechanical properties formed by the condensation reaction of polyols and polyisocyanates and has strong plasticity. Carbon fiber is mainly composed of carbon elements and has the characteristics of high temperature resistance, friction resistance, thermal conductivity and corrosion resistance, and has a fibrous appearance. In order to enhance the characteristics of composite materials, the semi-finished products of polyurethane carbon fiber need to be impregnated during the production process, and then the edge materials are cut and removed after drying and curing to obtain the finished product. The process of cutting the edge materials is mostly carried out on an edge material cutting machine.

[0003] When cutting the edge material of polyurethane carbon fiber impregnation material, cutting flying chips and powder will be generated. The dispersed flying chips and powder will increase the possibility of contact with the cutting tool, thereby increasing the working pressure of the cutting tool and shortening the service life of the tool.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] The invention discloses a device for cutting edge material of a formed polyurethane carbon fiber prepreg, which is mainly used in the scenario where the dispersed flying chips and powder increase the possibility of contact with the cutting tool and the working pressure of the cutting tool.

[0031] Reference Figure 1-10 A device for cutting edge material of formed polyurethane carbon fiber prepreg comprises a front frame 1 and a rear frame 2, two workbenches 3 are arranged between the front frame 1 and the rear frame 2, the two workbenches 3 are symmetrically distributed on the upper and lower sides of the material body, and a debris processing assembly 4 is arranged on the two workbenches 3, the debris processing assembly 4 comprises two upper covering boxes 401 and two lower covering boxes 402, the two upper covering boxes 401 are symmetrically distributed on both sides of the upper workbench 3, the two lower covering boxes 402 are symmetrically distributed on both sides of the lower workbench 3, and the material body is located between the upper covering box 401 and the lower covering box 402.

[0032] Specifically, after the molded polyurethane carbon fiber prepreg is cured, it is transported between the two workbenches 3, and the edge materials of the material body are cut and trimmed in the upper covering box 401 and the lower covering box 402. During cutting, the debris processing component 4 will quickly clean up the flying chips and powder generated in the cutting process; when the device is cutting the edge materials of the molded polyurethane carbon fiber prepreg, the debris processing component 4 is used to assist in quickly removing the flying chips and powder generated in the cutting process, avoiding the cutting chips from being suspended and contacting the cutting tool 408 to increase the working pressure of the tool, and at the same time avoiding the flying chips and powder from entering the working space to pollute the air and affect the health of personnel.

[0033] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 , a rectangular hole is provided on one side of the upper cover box 401 and the lower cover box 402 close to the front frame 1, and an air inlet box 403 is connected to the outer side of the rectangular hole by bolts, and a ventilation box 404 is connected to the outer side of the air inlet box 403 by bolts, and a ventilation pipe 417 is connected between the two ventilation boxes 404 on the same side by bolts, and a discharge hole is provided on the side of the upper cover box 401 away from the air inlet box 403, and an upper discharge bin 405 is connected to the outer side of the discharge hole by bolts, and a discharge hole is provided at the bottom of the lower cover box 402, and a lower discharge bin 406 is connected to the outer side of the discharge hole by bolts; a cutting motor 407 is connected to the opposite side of the two lower cover boxes 402 by bolts, and a through hole is provided on the two lower cover boxes 402, and the output end of the cutting motor 407 is connected to a rotating shaft through a coupling, and the other end of the rotating shaft passes through the through holes of the adjacent lower cover boxes 402 and is connected to a cutting knife 408 by bolts, and the cutting knife 408 Located inside the lower cover box 402, the lower side of the upper cover box 401 and the upper side of the lower cover box 402 are both connected with adjacent plates 409 by bolts, and brushes 410 are arranged on the opposite sides of the two adjacent plates 409; the two upper cover boxes 401 each include an annular flow chamber 411 and a wake flow chamber 412, the annular flow chamber 411 is connected to the air inlet box 403, the wake flow chamber 412 is connected to the upper discharge bin 405, and a guide plate 413 is arranged in the annular flow chamber 411, and the guide plate 413 The guide plate 413 is connected to the inner wall of the upper cover box 401 by bolts, and is arc-shaped. The guide plate 413 has the same curvature as the inner wall of the annular flow chamber 411. A bottle-shaped flow duct 414 is provided on the guide plate 413, and the bottle-shaped flow duct 414 is at the same height as the air inlet box 403. A buffer frame 415 is provided inside the tail flow chamber 412, and the buffer frame 415 is connected to the inner wall of the upper cover box 401 by bolts. A buffer net 416 is provided on the buffer frame 415.

[0034] Specifically, the edge material cutting position is adjusted according to the specifications of the material body, and then the material body is continuously conveyed for edge material cutting (the cutting motor 407 is started to drive the cutting knife 408 to rotate, and the edge material of the material body is cut). The cutting process is carried out in the upper cover box 401 and the lower cover box 402. Since it is a sealed space, the flying chips and powder generated during cutting will remain in the upper cover box 401 and the lower cover box 402. During this process, the cooled gas enters the upper cover box 401 and the lower cover box 402 from the air inlet box 403. When the gas enters the upper cover box 401, due to the guiding effect of the guide plate 413, part of the gas will move up along the guide plate 413 and enter the annular The flow cavity 411 forms an airflow that fits the annular flow cavity 411 and the tail flow cavity 412. The flying debris and powder during cutting fly to the tail flow cavity 412 due to the initial potential energy provided by the cutting position, contact the buffer net 416 on the buffer frame 415 to reduce the potential energy, and then arrive at the upper discharge bin 405 driven by the airflow. Another part of the airflow directly acts on the cutting position through the bottle-shaped air flow duct 414, accelerates the air circulation around the cutting knife 408, and blows the flying debris and dust directly to the upper discharge bin 405. When the gas enters the lower cover box 402, it directly blows on the cutting knife 408 and is then discharged from the lower discharge bin 406.

[0035] In a specific application scenario, the debris handling component 4 is suitable for the debris and powder handling links of the edge material cutting and cutting process, that is, the debris handling component 4 uses the cooled gas to act on the outside of the cutting knife 408, which can play a cooling role while removing the debris and powder outside the cutting knife 408. The upper cover box 401 produces two airflow states under the guidance of the guide plate 413 and the bottle-shaped air duct 414. The airflow above the cutting knife 408 can change the movement state of the cutting flying chips in time, so that it can quickly reach the upper discharge bin 405 to avoid the flying chips from flowing back. The airflow horizontal with the cutting knife 408 can keep the flow direction opposite to the cutting rotation, providing further driving force for the dust and debris with initial potential energy during cutting, and accelerating the flow of dust and debris away from the cutting knife. The cutting knife 408 reduces the possibility of dust and debris contacting the cutting knife 408; the contact surfaces between the upper cover box 401 and the lower cover box 402 and the material body adopt adjacent plates 409 and brushes 410, which can form a sealed environment while ensuring the normal transportation of the material body, and prevent cutting dust and debris from overflowing into the working environment; the bottle-shaped air flow duct 414 adopts a method of gradually reducing the diameter, which can increase the flow rate of the air flow in the bottle-shaped air flow duct 414, thereby further improving the effect of blowing away dust and debris outside the cutting knife 408; the buffer net 416 on the buffer frame 415 adopts a rope mesh structure, which can reduce the kinetic energy of flying chips when they come into contact, avoid flying chips directly hitting the inside of the upper cover box 401 and rebounding to form reflux, and reduce the possibility of flying chips contacting the cutting knife 408.

The cutting process is carried out in the upper cover box 401 and the lower cover box 402. Since it is a sealed space, the flying chips and powder generated during cutting will remain in the upper cover box 401 and the lower cover box 402. During this process, the cooled gas enters the upper cover box 401 and the lower cover box 402 from the air inlet box 403 (the blower 8 injects the gas into the air cylinder 9. Under the rapid cooling effect of the semiconductor refrigeration plate 10, the cooled gas enters the upper cover box 401 and the lower cover box 402 on both sides from the two air cylinders 9). When the gas enters the upper cover box 401, due to the guide plate 413 Due to the guiding effect, part of the gas will move up along the guide plate 413 and enter the annular cavity 411 to form an airflow that fits the annular cavity 411 and the tail cavity 412. The flying debris and powder during cutting will fly to the tail cavity 412 due to the initial potential energy provided by the cutting position, and contact the buffer net 416 on the buffer frame 415 to reduce the potential energy, and then reach the upper discharge bin 405 driven by the airflow. Another part of the airflow directly acts on the cutting position through the bottle-shaped air duct 414, accelerating the gas circulation around the cutting knife 408, and blowing the flying debris and dust directly to the upper discharge bin 405; when the gas enters the lower cover box 402, it directly blows on the cutting knife 408, and then is discharged from the lower discharge bin 406.
