The technology involves weaving toughening materials with carbon fibers to achieve toughening. Although this method improves the toughness of composite materials and partially solves the problems of RTM process, the cost is quite high, and it results in excessively low fiber volume of composite materials and a significant decrease in in-plane mechanical properties. The technical effect is limited, so its application market is very limited. In China, there are currently no toughened high-performance carbon fiber fabric products. Summary of the Invention

[0022] Please see Figure 1-5One embodiment of the present invention provides an apparatus for the continuous large-scale preparation of surface-loaded carbon fiber fabrics, comprising a support frame 10, a displacement plate 14 slidably mounted on the upper end face of the support frame 10, a height plate 33 fixedly mounted on the rear side of the upper end face of the displacement plate 14, a power gear 24 rotatably mounted on the height plate 33 via a power element, the power element being a motor, the power gear 24 being connected to a printing mechanism 38, the printing mechanism 38 including a printing cylinder 22 above the power gear 24, and transmission gears 23 fixedly mounted on both end faces of the printing cylinder 22. The transmission gear 23 meshes with the power gear 24 for transmission. The printing cylinder 22 has a motion shaft 28 in its inner cavity. A scraper 29 is fixedly installed on the motion shaft 28. A dripping tube 30 is fixedly installed on the scraper 29. The dripping tube 30 has an opening. Liquid slides down the scraper 29 from the opening on the dripping tube 30. The scraper 29 has a row of rotatable sharp blocks 31. The support frame 10 has an unwinding machine 18 on one side and an oven 19 on the other side. The oven 19 has a winding machine 21 on the side opposite to the support frame 10.

[0023] In another embodiment, a fixed gear 25 is rotatably mounted on the side wall of the height plate 33 facing the printing mechanism 38. A suspension rod 27 is rotatably mounted on the fixed gear 25, and an auxiliary gear 26 is rotatably mounted on the other end face of the suspension rod 27. The fixed gear 25 and the auxiliary gear 26 respectively mesh with the transmission gear 23 in the printing mechanism 38. The fixed gear 25 and the auxiliary gear 26 stabilize the printing mechanism 38 and stably mesh the printing mechanism 38 with the power gear 24.

[0024] In another embodiment, a drive element 35 is fixedly installed on the scraper 29. The drive element 35 is a motor. The output end of the drive element 35 is provided with a power disk 36. All the sharp blocks 31 are connected by a rotating shaft through a connecting block 32. The connecting block 32 and the power disk 36 are hingedly connected by a connecting rod 37.

[0025] In another embodiment, a liquid pump 15 is fixedly installed on the upper end face of the displacement plate 14. The inlet of the liquid pump 15 is connected to the solution tank 17 through a hose 16. The solution tank 17 contains a toughening agent. The outlet of the liquid pump 15 is connected to the dripping pipe 30.

[0026] In another embodiment, a mounting plate 11 is fixedly installed on the side wall of the support frame 10 near the unwinding machine 18. Two transport rollers 13 are arranged sequentially from top to bottom on the mounting plate 11. An auxiliary plate 12 is fixedly installed on the other side of the support frame 10. Three transport rollers 13 are arranged sequentially on the auxiliary plate 12. A fixing plate 20 is fixedly installed on the side of the drying oven 19 near the winding machine 21. Three transport rollers 13 are arranged on the fixing plate 20.

[0027] In practice, the pump 15 is started, and the pump 15 draws toughening agent from the solution tank 17 through the hose 16. The agent then flows to the drip pipe 30, and drips onto the surface of the scraper 29 through the upper opening of the drip pipe 30. Then, the drive element 35 is started, which drives the power disk 36 to rotate. The power disk 36 drives the connecting block 32 to reciprocate through the connecting rod 37. Simultaneously, the connecting block 32 drives a pair of sharp blocks 31 to repeatedly swing, evenly spreading the toughening agent dripped from the drip pipe 30 onto the surface of the scraper 29. Then, the guide rail 34 is activated, which drives the motion shaft 28 and the scraper 29 to move towards the inner wall of the printing cylinder 22 until one end of the scraper 29 contacts the inner wall of the printing cylinder 22. Through the continuous swinging of the sharp block 31, the toughening agent is evenly spread on the surface of the scraper 29, so that the toughening agent can fall evenly on the inner wall of the printing cylinder 22, making the toughening agent evenly distributed in the wall of the printing cylinder 22. This solves the problem of insufficient and uneven toughening agent on the wall of the printing cylinder 22, thus making the printed pattern on the wall of the printing cylinder 22 clearer.

[0028] The unwinding machine 18 is started, and the carbon fiber fabric is conveyed by the unwinding machine 18, passing around the two transport rollers 13 on the mounting plate 11, then passing through the support frame 10, passing around the three transport rollers 13 on the auxiliary plate 12, and sliding the displacement plate 14. The displacement plate 14 drives the whole to move to the right, so that the printing cylinder 22 contacts the transport roller 13 on the uppermost end face of the auxiliary plate 12. At this time, the carbon fiber fabric is sandwiched between the two. Then, the power element is started to drive the power gear 24 to rotate, the power gear 24 drives the transmission gear 23 to rotate, and the transmission gear 23 drives the printing cylinder 22 to rotate. When the printing cylinder 22 rotates, the scraper 29 continuously scrapes the inner wall of the printing cylinder 22, and the toughening agent on the wall of the printing cylinder 22 is printed onto the carbon fiber fabric through the pattern on the wall of the printing cylinder 22. Then, it is dried in the drying oven 19 and finally collected on the winding machine 21. The pattern on the wall of the printing cylinder 22 can be changed according to different requirements, which makes it more adaptable. At the same time, the internal components of the printing mechanism 38 are simple and easy to replace.
