[0017] The features of the present invention and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0019] As described above, the structure of this case is simple and easy to implement. The setting of the first protective layer winding mechanism 2 and the setting of the second protective layer winding mechanism 4 facilitate the removal of the upper and lower protective layers of the prepreg, so that the warp prepreg 101 and the weft prepreg 102 after being woven by the warp and weft weaving mechanism 5 can adhere to each other, which has good practicability; the setting of the attaching protective layer mechanism 6 facilitates attaching protective layers to the upper and lower ends of the woven warp and weft prepreg 103, so that the inner and outer layers will not adhere to each other during subsequent winding, which is convenient for subsequent use and has good practicability; the setting of the rolling and pressing mechanism 7 facilitates ensuring that the protective layer is tightly attached to the warp and weft prepreg 103, which has good practicability; this case realizes the mechanized weaving and winding of the prepreg, which is beneficial to improving production efficiency, ensuring product quality, avoiding the risk of deformation caused by impregnating resin after weaving and avoiding the risk of incomplete penetration of impregnating resin, and has good practicability.

[0020] As Figure 1 shown, in specific implementation, the first protective layer winding mechanism 2 includes a first roller 21 for winding the upper protective layer of the warp prepreg 101 thereon, a first driver 22 for driving the first roller 21 to rotate to facilitate winding the upper protective layer of the warp prepreg 101, a second roller 23 for winding the lower protective layer of the warp prepreg 101 thereon, and a second driver 24 for driving the second roller 23 to rotate to facilitate winding the lower protective layer of the warp prepreg 101.

[0021] As described above, the specific arrangement of the first protective layer winding mechanism 2 in this case is convenient to implement. During operation, the free end of the protective layer can be manually wound onto the corresponding roller first, and then the roller is driven to rotate by the corresponding driver to wind the protective layer.

[0022] As Figure 1 shown, during specific implementation, the second protective layer winding mechanism 4 includes a third roller 41 for winding the upper protective layer of the weft pre-impregnated material 102 thereon, a third driver 42 for driving the third roller 41 to rotate to facilitate winding the upper protective layer of the weft pre-impregnated material 102, a fourth roller 43 for winding the lower protective layer of the weft pre-impregnated material 102 thereon, and a fourth driver 44 for driving the fourth roller 43 to rotate to facilitate winding the lower protective layer of the warp pre-impregnated material 101.

[0023] As described above, the specific arrangement of the second protective layer winding mechanism 4 in this case is convenient to implement. During operation, the free end of the protective layer can be manually wound onto the corresponding roller first, and then the roller is driven to rotate by the corresponding driver to wind the protective layer.

[0024] As Figure 2 shown, during specific implementation, the warp and weft weaving mechanism 5 includes an upper and lower shuttle frame assembly 51 for vertically displacing multiple passing warp pre-impregnated materials 101 as needed to leave a displacement space for the weft pre-impregnated material 102 to be woven therein, a conduit 52 located at the first end of the displacement space for the weft pre-impregnated material 102 released from the weft supply rack 3 to pass through, a chuck 53 for clamping the weft pre-impregnated material 102 at the outlet of the conduit 52 to the second end of the displacement space, a fifth driver 54 for driving the chuck 53 to move back and forth in the displacement space along the weft direction, and a knife body 55 for severing the weft pre-impregnated material 102 at the outlet of the conduit 52 after the weft pre-impregnated material 102 is clamped to the other end of the displacement space.

[0025] As described above, the arrangement of the conduit 52 in this case facilitates specifying the output position of the weft pre-impregnated material 102, so that the fifth driver 54 can drive the chuck 53 to move to the output port of the conduit 52 to clamp the weft pre-impregnated material 102. The arrangement of the upper and lower shuttle frame assembly 51 facilitates vertically displacing multiple passing warp pre-impregnated materials 101 to leave a displacement space for the weft pre-impregnated material 102 to be woven therein. The arrangement of the knife body 55 facilitates obtaining the weft pre-impregnated material 102 of the required length, so that the warp and weft weaving mechanism 5 can weave the weft pre-impregnated material 102 into multiple warp pre-impregnated materials 101 time by time. It is convenient to implement and has good practicality.

[0026] As Figure 2As shown, in specific implementation, the upper and lower shuttle frame assembly 51 includes an upper shuttle frame 511 capable of moving up and down, which presses the designated warp prepreg 101 downward when moving from top to bottom to facilitate vertical dislocation with the remaining warp prepregs 101 to form a dislocation space, a sixth driver 512 for driving the upper shuttle frame 511 to move up and down, a lower shuttle frame 513 capable of moving up and down, which presses the designated warp prepreg 101 upward when moving from bottom to top to facilitate vertical dislocation with the remaining warp prepregs 101 to form a dislocation space, and a seventh driver 514 for driving the lower shuttle frame 513 to move up and down, and its implementation is convenient.

[0027] In addition, in specific implementation, the upper and lower shuttle frame assembly 51 in this case can also adopt other implementation methods. For example, the upper shuttle frame 511 and the lower shuttle frame 513 are connected together, and are driven to move up and down synchronously by a driver. When working, multiple warp prepregs 101 are divided into two groups. When the upper shuttle frame 511 and the lower shuttle frame 513 move up and down together, they both drive multiple warp prepregs 101 in the first group to move up and down to facilitate vertical dislocation with the remaining multiple warp prepregs 101 in the second group to form a dislocation space.

[0028] As Figure 1 As shown, in specific implementation, the protective layer attaching mechanism 6 includes an upper side unwinding rack 61 located on the upper side, a fifth roller 62 for attaching the protective layer unwound from the upper side unwinding rack 61 to the upper end face of the warp and weft prepreg 103, a lower side unwinding rack 63 located on the lower side, and a sixth roller 64 for attaching the protective layer unwound from the lower side unwinding rack 63 to the lower end face of the warp and weft prepreg 103, and its implementation is convenient.

[0029] As Figure 1 As shown, in specific implementation, the rolling mechanism 7 includes a seventh roller 71 for rolling the upper end face of the warp and weft prepreg 103 after attaching the protective layer and an eighth roller 72 for rolling the lower end face of the warp and weft prepreg 103 after attaching the protective layer. The seventh roller 71 and the eighth roller 72 are vertically opposite to each other, and its implementation is convenient.

[0030] As described above, in specific implementation, each driver in this case can be selected as a drive motor assembly or a drive cylinder assembly according to actual conditions to facilitate the driving of the corresponding components.

[0031] As described above, what this case protects is a mechanized weaving device for prepregs. All technical solutions identical or similar to this case should be regarded as falling within the protection scope of this case.
