[0002] Fiber prepreg processing equipment refers to equipment used for processing and handling prepregs, such as impregnation machines, cooling machines, and cutting machines. Prepregs refer to composite materials in which fiber materials and resins have been pre-impregnated and permeated through a specific process.

[0003] When cutting polyacrylonitrile-based carbon fiber prepreg using a cutting machine, the prepreg is laid flat on the machine. The internal drive mechanism then moves the carriage along the machine according to the cutting requirements. Simultaneously, the drive mechanism inside the carriage moves the laser cutting head up and down to cut the prepreg. During the conveying process, dust and impurities adhere to the surface of the prepreg, which can obstruct the laser beam from effectively focusing on the intended cutting area, resulting in uneven cutting and reduced cutting quality and effectiveness. Utility Model Content

[0004] The technical problem to be solved by this utility model is that during the conveying process of polyacrylonitrile-based carbon fiber prepreg, dust and impurities will adhere to the surface of the polyacrylonitrile-based carbon fiber prepreg, which will prevent the laser beam from being effectively focused on the predetermined cutting area during the cutting process, resulting in uneven cutting and reducing the cutting quality and effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a fiber prepreg processing equipment, including a cutting machine, a sliding frame slidably installed on one side of the cutting machine, a laser cutting head provided on one side of the sliding frame, and a cleaning device provided on one side of the cutting machine. The cleaning device can use a first motor to drive an adhesive roller to roll on the surface of the polyacrylonitrile-based carbon fiber prepreg for cleaning, and at the same time, use an air pump to draw gas into the nozzle to blow air to clean the surface of the polyacrylonitrile-based carbon fiber prepreg, so as to make it cleaner.

[0006] The effect achieved by the above components is as follows: When using a cutting machine to cut polyacrylonitrile-based carbon fiber prepreg, the polyacrylonitrile-based carbon fiber prepreg is laid flat on the cutting machine. Then, the cleaning device is activated to clean the surface of the polyacrylonitrile-based carbon fiber prepreg to avoid affecting the focusing of the laser beam and causing uneven cutting, thereby improving the cutting quality and effect. Then, the drive component inside the cutting machine is activated to drive the slide to slide on the cutting machine according to the actual usage requirements. At the same time, according to the cutting requirements, the drive component inside the slide is activated to drive the laser cutting head to move up and down to cut the polyacrylonitrile-based carbon fiber prepreg.

[0007] Preferably, the cleaning device includes a drive mechanism, a screw hole block, a bracket, a slider, and a first motor, wherein the screw hole block is mounted on one side of the cutting machine by means of the drive mechanism, and a detachable device is provided between the screw hole block and the bracket; a threaded groove rod, wherein one end of the threaded groove rod passes through one side of the slider, and the other end is fixedly connected to the output end of the first motor by means of a coupling; an adhesive roller, wherein the outer surface of one end of the adhesive roller is threaded into the inner wall of one end of the threaded groove rod; an adjustment mechanism, wherein the adjustment mechanism is installed between the slider and the bracket, and is used to adjust the height of the threaded groove rod and the adhesive roller; a guide rod, wherein one end of the guide rod is fixedly mounted on one side of the bracket, and spray pipes are symmetrically mounted on both sides of the guide rod; and an air pump, wherein the outlet of the air pump is installed through one side of the guide rod.

Then, with the help of the adjustment mechanism, one end of the adhesive roller is tightly attached to the surface of the polyacrylonitrile-based carbon fiber prepreg. Then, the air pump is started to draw external air into the guide rod, then guides it into the nozzle, and finally discharges it from the nozzle, blowing away large particles of dust and impurities adhering to the surface of the polyacrylonitrile-based carbon fiber prepreg. At the same time, the first motor is started, carrying... The moving threaded groove rod and the adhesive roller rotate on the slider. At this time, the drive mechanism is activated to drive the screw hole block to slide to one end, causing the bracket, adhesive roller, and nozzle to move back and forth on the surface of the polyacrylonitrile-based carbon fiber prepreg to clean the surface. The first motor and the second motor are both servo motors. This allows the first motor and the second motor to be set so that the direction of rotation of the adhesive roller is always opposite to the direction of movement of the screw hole block. This cleans away the dust and impurities adhering to the surface of the polyacrylonitrile-based carbon fiber prepreg, avoiding uneven cutting caused by affecting the focus of the laser beam, and improving the cutting quality and effect.

[0009] Preferably, a filter screen is fixedly installed on the inner wall of the nozzle, and the filter screen is installed in the inner wall of the end of the nozzle away from the guide rod.

[0014] The effect achieved by the above components is as follows: By setting an adjustment mechanism, the adhesive roller can be screwed onto one end of a threaded groove rod according to the thickness of the polyacrylonitrile-based carbon fiber prepreg that needs to be cleaned. The threaded groove rod can be pulled upward to a certain position, causing the slider to slide upward in the groove, which in turn causes the spring and telescopic rod to contract. After the polyacrylonitrile-based carbon fiber prepreg is placed, the threaded groove rod is released, and under the reset action of the spring and telescopic rod, the surface of the adhesive roller can be tightly attached to the surface of the polyacrylonitrile-based carbon fiber prepreg, making it convenient for the adhesive roller to clean the surface of polyacrylonitrile-based carbon fiber prepreg of different thicknesses.

[0015] Preferably, the detachable device includes a locking rod, with first locking holes on both sides of the inner wall of the screw hole block, and a second locking hole at one end of the bracket, the latter of which is inserted into the inner wall of one side of the screw hole block; a round block, one end of which is slidably mounted in the inner wall of one end of the locking rod, and a locking block rotatably mounted on one end of the round block, the locking rod, the round block, and the locking block all being inserted into the inner walls of the first and second locking holes; and a second spring, the two ends of which are respectively fixedly mounted on one side of the inner wall of the locking rod and one side of the round block.

[0016] The effect achieved by the above components is as follows: By setting a detachable device, when it is necessary to replace the bracket and guide rod, the locking block can be manually held and rotated to a certain angle on one side of the round block to align it with the first locking hole. After releasing the locking block, the locking block and the round block will be reset to one end by the spring and retract into the first locking hole. Then, the locking rod can be held and pulled out from the inner wall of the first and second locking holes to release the restriction on the bracket.

[0031] Figure 1-4The fiber prepreg processing equipment shown includes a cutting machine 1. A sliding frame 4 is slidably mounted on one side of the cutting machine 1, and a laser cutting head 5 is disposed on one side of the sliding frame 4. A cleaning device 2 is disposed on one side of the cutting machine 1. The cleaning device 2 can drive an adhesive roller 28 to roll on the surface of the polyacrylonitrile-based carbon fiber prepreg via a first motor 27 for cleaning. Simultaneously, air is drawn into the nozzle 211 by an air pump 210 to blow air onto the surface of the polyacrylonitrile-based carbon fiber prepreg for cleaning, making it more thoroughly cleaned. When using the cutting machine 1 to cut the polyacrylonitrile-based carbon fiber prepreg, the polyacrylonitrile-based carbon fiber prepreg is laid flat on the cutting machine 1. Then, the cleaning device 2 is activated to first clean the surface of the polyacrylonitrile-based carbon fiber prepreg to avoid affecting the focusing of the laser beam and causing uneven cutting, thereby improving the cutting quality and effect. Then, the drive component inside the cutting machine 1 is activated to drive the sliding frame to slide on the cutting machine 1 according to the actual usage requirements. At the same time, the drive component inside the sliding frame is activated to drive the laser cutting head 5 up and down according to the cutting requirements to cut the polyacrylonitrile-based carbon fiber prepreg.

[0032] Figure 1-4The cleaning device 2 shown includes a drive mechanism 22, a screw hole block 21, a bracket 23, a slider 25, and a first motor 27. The screw hole block 21 is mounted on one side of the cutting machine 1 via the drive mechanism 22, and a detachable device 3 is provided between the screw hole block 21 and the bracket 23. A threaded groove rod 26 is shown, with one end of the threaded groove rod 26 passing through one side of the slider 25 and the other end fixedly connected to the output end of the first motor 27 via a coupling. An adhesive roller 28 is shown, with one end of the adhesive roller 28 threaded into the inner wall of one end of the threaded groove rod 26. An adjustment mechanism 24 is shown, which is installed between the slider 25 and the bracket 23 to adjust the height of the threaded groove rod 26 and the adhesive roller 28. A guide rod 29 is shown, with one end of the guide rod 29 fixedly mounted on one side of the bracket 23, and spray pipes 211 symmetrically mounted on both sides of the guide rod 29. An air pump 210 is shown, with its outlet installed through one side of the guide rod 29. After the polyacrylonitrile-based carbon fiber prepreg is laid flat on the cutting machine 1, before cutting, according to the thickness of the polyacrylonitrile-based carbon fiber prepreg, the adhesive roller 28 is screwed into the inner wall of the threaded groove rod 26. Then, with the help of the adjusting mechanism 24, one end of the adhesive roller 28 is tightly attached to the surface of the polyacrylonitrile-based carbon fiber prepreg. Then, the air pump 210 is started to draw external air into the guide rod 29, then guides it into the nozzle 211, and finally discharges it from the nozzle 211, blowing away large particles of dust and impurities adhering to the surface of the polyacrylonitrile-based carbon fiber prepreg. At the same time, the first motor 27 is started to drive the threaded groove rod 26 and the adhesive roller 28 to slide. When block 25 rotates, the drive mechanism 22 is activated, causing the screw hole block 21 to slide to one end. This causes the bracket 23, adhesive roller 28, and nozzle 211 to move back and forth on the surface of the polyacrylonitrile-based carbon fiber prepreg, cleaning its surface. Both the first motor 27 and the second motor 221 are servo motors. These motors can be configured to ensure that the direction of rotation of the adhesive roller 28 is always opposite to the direction of movement of the screw hole block 21, cleaning away dust and impurities adhering to the surface of the polyacrylonitrile-based carbon fiber prepreg. This prevents uneven cutting caused by affecting the laser beam focus, improving cutting quality and effect. A filter screen 212 is fixedly installed on the inner wall of the nozzle 211, located at the end of the nozzle 211 away from the guide rod 29. The filter screen 212 protects the inner wall of the nozzle 211, preventing external dust and impurities from entering and clogging it. It also filters the air drawn in by the air pump 210 before blowing it out.

[0033] Figure 1-4The drive mechanism 22 shown includes a threaded rod 222, one end of which is installed through the inner wall of one side of the cutting machine 1, and its outer surface is threadedly connected to the inner wall of the screw hole block 21. One end of the screw hole block 21 is slidably installed in the inner wall of one side of the cutting machine 1. A second motor 221 is fixedly installed on one side of the cutting machine 1, and its output end is fixedly installed on one end of the threaded rod 222 via a coupling. When cleaning the surface of the polyacrylonitrile-based carbon fiber prepreg using the cleaning device 2, the second motor 221 can be started to drive the threaded rod 222 to rotate in the inner wall of one side of the cutting machine 1. This causes the screw hole block 21 to move back and forth in the inner wall of the cutting machine 1, which in turn causes the support 23, the adhesive roller 28, and the nozzle 211 to move back and forth on the surface of the polyacrylonitrile-based carbon fiber prepreg for cleaning. The adjustment mechanism 24 includes a first spring 241, a slide groove 243 on one side of the bracket 23, the inner wall of the slide groove 243 being slidably connected to the outer surface of the slider 25, wherein the two ends of the first spring 241 are respectively fixedly installed on one side of the slider 25 and one side of the inner wall of the slide groove 243; and a telescopic rod 242, wherein the outer surface of the telescopic rod 242 passes through the inner wall of the first spring 241, and the two ends are respectively fixedly installed on one side of the slider 25 and one side of the inner wall of the slide groove 243. Depending on the thickness of the polyacrylonitrile-based carbon fiber prepreg that needs cleaning, after the adhesive roller 28 is spirally installed on one end of the threaded groove rod 26, the threaded groove rod 26 can be pulled upward to a certain position, causing the slider 25 to slide upward in the groove 243, which causes the spring and telescopic rod 242 to contract. At this time, after the polyacrylonitrile-based carbon fiber prepreg is placed, the threaded groove rod is loosened, so that under the reset action of the spring and telescopic rod 242, the surface of the adhesive roller 28 can be tightly attached to the surface of the polyacrylonitrile-based carbon fiber prepreg, which makes it convenient for the adhesive roller 28 to clean the surface of polyacrylonitrile-based carbon fiber prepreg of different thicknesses.

When it is necessary to replace the bracket 23 and the guide rod 29, you can manually hold the locking block 36 and rotate it to a certain angle on one side of the round block 35 so that it is aligned with the first locking hole 31. Release the locking block 36, and the locking block 36 and the round block 35 will return to one end with the help of the spring and retract into the first locking hole 31. Then hold the locking rod 33 and pull it out from the inner wall of the first locking hole 31 and the second locking hole 32 to release the restriction on the bracket 23. Finally, pull the bracket 23 to one end to remove it from the screw hole block 21 and the cutting machine 1 for easy replacement and storage.

[0035] Figure 1-4 The first locking hole 31 shown has locking grooves 37 on both sides of its inner wall, and the locking block 36 is inserted into the inner wall of the locking groove 37. By setting the locking grooves 37, after the locking rod 33, the round block 35, and the locking block 36 are inserted into the first locking hole 31 and the second locking hole 32, the locking block 36 can be pulled to move the round block 35 to a certain position in the inner wall of the locking rod 33 with the help of the spring. Then, after rotating it ninety degrees, it is locked into the locking groove 37, which provides a secondary limiting and fixing for the locking block 36, making the locking and fixing more secure. A connecting rope 38 is fixedly installed on one side of the locking rod 33, and one end of the connecting rope 38 is fixedly installed on one side of the screw hole block 21. By setting the connecting rope 38, the locking rod 33 can be fixedly fixed on one side of the screw hole block 21, so that it is not easy to lose when not in use.

Then, with the help of the adjusting mechanism 24, one end of the adhesive roller 28 is tightly attached to the surface of the prepreg. Then, the air pump 210 is started to draw external air into the guide rod 29, then guides it into the nozzle 211, and finally discharges it from the nozzle 211, blowing away large dust and impurities adhering to the surface of the prepreg. At the same time, the first motor 27 is started, driving the threaded groove rod 26 and the adhesive roller 28 to rotate on the slider 25. Then, the drive mechanism 2 is started. 2. The screw hole block 21 is slid to one end, causing the bracket 23, adhesive roller 28, and nozzle 211 to move back and forth on the surface of the polyacrylonitrile-based carbon fiber prepreg to clean the surface. The first motor 27 and the second motor 221 are both servo motors. The first motor 27 and the second motor 221 can be set so that the direction of rotation of the adhesive roller 28 is always opposite to the direction of movement of the screw hole block 21, cleaning away the dust and impurities attached to the surface of the polyacrylonitrile-based carbon fiber prepreg, avoiding uneven cutting caused by affecting the focus of the laser beam, and improving the cutting quality and effect. Then, the drive component inside the cutting machine 1 is started to drive the slide to slide on the cutting machine 1 according to the actual use requirements. At the same time, the drive component inside the slide is started to drive the laser cutting head 5 to move up and down according to the cutting requirements, and to cut the polyacrylonitrile-based carbon fiber prepreg.

[0037] When it is necessary to replace the bracket 23 and the guide rod 29, you can manually hold the locking block 36 and pull it to one end to pull it out of the locking slot 37.
