DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0034] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0035] As shown in the figure, a carbon fiber pultruded plate production line for wind turbine main beams includes a yarn release component 11 and an impregnation box 2, the yarn release component includes a receiving box 3, a plurality of first wire holes 4 are evenly opened on the side of the receiving box 3 facing the impregnation box 2, a yarn straightening component 5 is also arranged between the receiving box 3 and the impregnation box 2, a guide frame 6 is arranged on the side of the impregnation box 2 relative to the receiving box 3, a covering component 7, an extrusion component 8, a high-temperature curing component 9, and a traction component 10 are arranged on the guide frame 6, a winding component 11 is also arranged on the side located at the rear end of the guide frame 6, and a cutting component 12 is also arranged at the rear end of the guide frame 6.

[0036] The unwinding assembly 11 can automatically unwind multiple rolls of carbon fiber raw materials. The unwinding carbon fiber bundle is straightened by the yarn straightening assembly 5 and then enters the impregnation box 2 for glue dipping. It then passes through the covering assembly 7, the extrusion assembly 8 and the high-temperature curing assembly 9 to form a carbon fiber extruded board. Finally, it is wound up by the winding assembly 11. After a roll of the board is wound up, it is cut off by cutting, so that it can be processed fully automatically, which effectively improves the production efficiency.

[0037] There are two containing boxes 3, which include vertically arranged support plates 301, baffles 302 are arranged on the circumferential sides of the opposite surfaces of the two support plates 301, a plurality of unwinding rollers 13 are passed through and rotatably connected to the two support plates 301, and also include a first driving member for driving the unwinding rollers 13, and the circumferential surface of the unwinding rollers 13 extending into the two containing boxes 3 is provided with two relatively arranged support rings 14, and also include a second driving member for driving the two support rings 14 to expand or contract.

[0038] The first driving member includes two pulleys 15 arranged on each unwinding roller 13, the two pulleys 15 are located between the two containing boxes 3, a belt 16 is arranged between two adjacent unwinding rollers 13 located at the same height, and also includes a first motor 17 for driving one of the unwinding rollers 13 at a different height position, and the first motor 17 drives one of the unwinding rollers 13 to rotate through gears.

[0039] The unwinding roller 13 is provided with a through groove running through its two side surfaces along its length direction. The second driving member includes a connecting block 18 arranged on the inner surface of the support ring 14. The connecting block 18 slides in the through groove along the vertical direction. Both sides of the connecting block 18 are hinged with hinged rods 19, two of which are hinged at the middle of the inner wall of the end of the through groove. Two driving blocks 20 are arranged in the through groove between the two groups of support rings 14, and the other two hinged rods 19 are hinged at one side of the driving block 20. A bidirectional cylinder 21 is arranged in the middle of the through groove for controlling the relative or away movement of the two driving blocks 20.

[0040] Before production and processing, the wound carbon fiber raw material is sleeved on the unwinding roller 13, and the two driving blocks 20 are driven to move away by the two-way cylinder 21. Under the action of the hinged rod 19, the two support rings 14 are driven to open, thereby ensuring the stability of the carbon fiber raw material during unwinding, thereby ensuring the pay-off speed of the carbon fiber raw material.

[0041] The yarn straightening assembly 5 includes a first yarn straightening plate 22 vertically arranged between the receiving box 3 and the impregnation box 2, a plurality of second yarn guide holes 23 are evenly opened on the first yarn straightening plate 22, a second yarn straightening plate 24 is arranged on the top of one side of the impregnation box 2 close to the first yarn straightening plate 22, and third yarn guide holes 25 are evenly opened on the second yarn straightening plate 24, the density of the first yarn guide holes is less than the density of the second yarn guide holes 23, and the density of the second yarn guide holes 23 is less than the density of the third yarn guide holes 25. The carbon fiber passes through the first yarn guide hole, the second yarn guide hole 23 and the third yarn guide hole 25 at one time, so that the density of the carbon fiber bundle gradually increases, so that it can be gradually gathered and enter the impregnation box 2 for dipping.

[0042] A guide roller 26 is provided at the bottom of the impregnation box 2, and support rods 27 are provided on both sides of the top of the impregnation box 2 on the side close to the guide frame 6. A plurality of first squeezing rollers 28 are provided between the two support rods 27. The carbon fiber bundle passes around the bottom of the guide roller 26, thereby ensuring that the carbon fiber bundle can be fully impregnated in the resin.

[0043] L-shaped rods 29 are arranged on both sides of the end of the guide frame 6 facing the impregnation box 2, a plurality of second squeezing rollers 30 are arranged between the two L-shaped rods 29, a guide plate 31 is arranged between the L-shaped rod 29 and the support rod 27, and the guide plate 31 is inclined toward one end of the impregnation box 2. After impregnation, the carbon fiber bundle first passes between the first squeezing roller 28 and the second squeezing roller 30, thereby squeezing off the excess resin on the carbon fiber bundle, and the excess resin falls on the guide plate 31 and then flows back into the impregnation box 2 along the guide plate 31.

[0044] The winding assembly 11 includes a vertically arranged fixed plate 32, and a rotating shaft 33 is rotatably connected to one side surface of the fixed plate 32. A third driving member (not shown in the figure, which is specifically a motor) for driving the rotating shaft 33 is arranged on the fixed plate 32. A rotating plate 34 is arranged at the end of the rotating shaft 33. Four driving cylinders 35 are evenly arranged on the inner surface of the rotating plate 34 along its circumferential direction. A winding block 36 is fixedly connected to the end of the output shaft of the driving cylinder 35. The winding block 36 includes a bottom wall 3601 with a horizontal bottom and an outer wall 3602 with an arc shape. The bottom wall 3601 is provided with a fixed block 37 fixedly connected to the output shaft of the driving cylinder 35.

[0045] During the winding process, the driving cylinder 35 drives several winding blocks 36 to open in a direction away from the rotating shaft 33. After the winding is completed, the driving cylinder 35 drives the winding blocks 36 to reset, so that the wound carbon fiber pultruded sheet can be easily unloaded.

[0046] A clamping plate 38 is provided on the bottom wall 3601 of one of the winding blocks 36, and bottom plates 39 are provided on both sides of the bottom wall 3601. The middle parts of the clamping plate 38 are rotatably connected to the two bottom plates 39 on both sides, and one end of the clamping plate 38 facing the fixed block is hinged with a movable rod 40, and the other end of the movable rod 40 is hinged to the inner surface of the rotating plate 34. Before the winding work is performed, the end of the carbon fiber pultruded sheet is extended between the clamping plate 38 and the bottom wall. When the driving cylinder drives the winding block 36 to open, the clamping plate 38 is deflected under the action of the movable rod 40, so that the end of the carbon fiber pultruded sheet is clamped, and the rotating shaft 33 is driven to rotate by the third driving member to wind the carbon fiber pultruded sheet around the outer wall surface of the winding block. After the winding is completed, the driving cylinder drives the winding block to reset, and at the same time drives the clamping plate 38 to reset, so that the rolled carbon fiber pultruded sheet can be easily unloaded.

[0047] The surface of the fixed plate 32 is provided with a side plate 41 along its circumference, and a feed port 42 is provided at the top of the side plate 41 facing the guide frame 6, and connecting plates 43 are provided on both sides of the side plate 41 located at the feed port 42, and a feed roller 44 is rotatably connected between the two connecting plates 43, and a second motor 45 for driving one feed roller 44 is installed on one connecting plate 43. The end of the carbon fiber pultruded sheet passes through between the two feed rollers 44 and extends into the feed port 42 to roll up the carbon fiber pultruded sheet.

[0048] The covering assembly 7, the extrusion assembly 88, the high temperature curing assembly 99, and the pulling assembly 1010 are all prior arts and will not be described in detail in this embodiment.

[0049] A process for producing a carbon fiber extruded sheet for a wind power main beam comprises the following steps:

[0050] S1, yarn distribution: the rolled carbon fiber raw material is placed in the containing box 3, and the carbon fiber is discharged from the containing box 3 and passes through the yarn straightening assembly 5 to be tightly and neatly distributed;
