Description

Technical Field

[0001] The present invention relates to the technical field of carbon fiber, and specifically provides a resin softening and stretching device for the production of carbon fiber filaments. Background Technique

[0002] Carbon fiber filaments refer to high-strength and high-modulus fibers with a carbon content of more than 90%. They have the highest heat resistance among all chemical fibers. They are made from acrylic fibers and viscose fibers as raw materials and are formed by high-temperature oxidation and carbonization. They are excellent materials for manufacturing high-tech equipment such as aerospace. When producing carbon fiber filaments, the resin needs to be softened and then stretched. This is the first step in the carbon fiber production process, mainly separating the resin into fibers, which belongs to a physical change. During this process, mass transfer and heat transfer occur between the spinning solution stream and the coagulating solution, and finally, PAN precipitates to form a gel-structured filament. Therefore, a stretching device is required.

[0003] Existing patent: CN215103722U discloses a resin softening and stretching device for the production of carbon fiber filaments, including a main box body, which is the installation base of the entire device. A fixed box is fixed on the main box body, and a guide wheel is connected to the main box body through a bearing for guiding, and the guide wheel is connected to the carbon fiber filament body; fixed frames are equally spaced and fixed on the main box body, and the fixed frames are connected to adjusting screws through threads, and the adjusting screws are vertically distributed with the fixed frames. At the same time, the adjusting screws are fixed to the mounting frame through bearings.

[0004] The above patents or existing stretching devices have the following problems:

[0005] The stretching rollers of the existing stretching devices need to press the carbon fiber filaments to maintain the stability of the carbon fiber filaments in the box body. In order to maintain the stability of the carbon fiber filaments, the positions of the stretching rollers need to be pressed. However, after the existing stretching rollers are adjusted, they are directly placed on the box body. During the stretching process of the carbon fiber filaments, the stretching rollers will be pulled and shifted, resulting in the instability of the stretching rollers. There is also the problem that it is not convenient for subsequent corresponding adjustments when locking the stretching rollers with bolts; the existing stretching devices are not convenient for diverting the carbon fiber filaments, resulting in the problem that the carbon fiber filaments may touch and stick to each other during the stretching process.

Detailed implementation manners

[0027] In order to further explain the technical solution of the present invention, the following will be elaborated in detail through specific embodiments.

[0028] Please refer to Figure 1 and Figure 2 , the present invention provides a resin softening and stretching device for carbon fiber filament production, including a box body 1. Cooling water is contained inside the box body 1. A bracket 2 is fixed to the bottom of the box body 1 by bolts. The bracket 2 is used to support the box body 1.

A stretching roller 31 is arranged on the box body 1, and the stretching roller 31 is fixed on the box body 1 through a sliding adjustment structure 4. When stretching the carbon fiber filaments, the carbon fiber is placed on the guide rollers 3 and then wound around the guide rollers 3. Then, one end of the carbon fiber is connected to a traction machine. Under the traction of the traction machine, the carbon fiber will be stretched into filaments on the stretching roller 31. A flow - dividing structure 5 is arranged at the side of the box body 1.

[0029] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the present invention provides a resin softening and stretching device for carbon fiber filament production. The sliding adjustment structure 4 includes a fixed rail 41. The fixed rail 41 is installed and fixed to the side of the box body 1 by bolts. A sliding frame 43 assembled on the fixed rail 41, and the sliding frame 43 is slidably connected to the fixed rail 41. The sliding frame 43 is integrally formed on the surface of the sliding box 42 to realize the installation of the sliding box 42 on the fixed rail 41;

[0030] A lever 431 rotatably connected by a torsion spring is assembled at the lower end of the sliding box 42. A driving gear 44 rotatably connected is installed inside the sliding box 42, and the driving gear 44 is connected to the lever 431. A driven gear 45 is assembled inside the sliding box 42, and the driven gear 45 is meshed with the driving gear 44. A rotating rod 46 is fixed in the middle of the driven gear 45. The rotating rod 46 is rotatably connected to the sliding box 42 and extends outside the sliding box 42. Two rotating plates 461 are rotatably arranged on the surface of the rotating rod 46. A reinforcing frame 462 in an "X" shape is welded between the two rotating plates 461 to improve the stability of the two rotating plates 46 and prevent the rotating rod 46 from swinging. A connecting rod 48 passes through the upper ends of the two rotating plates 461;

[0031] A pressing plate 49 is arranged at the lower end of the sliding frame 43. A side plate 410 is welded at the lower end of the pressing plate 49. A sliding groove 411 is formed on the side plate 410, and the connecting rod 48 is connected to the sliding groove 411;

[0032] An assembling block 47 is arranged at the upper end of the sliding box 42. The stretching roller 431 is rotatably connected to the assembling block 47;

[0033] The bottom of the sliding box 42 is fixed with a fixed box 412 by screws. A cross bar 413 is fixed inside the fixed box 412 by bolts. A spring 414 is assembled on the cross bar 413. A clamping rod 415 slidably connected is arranged on the cross bar 413. A dial 416 is fixed at the bottom of the clamping rod 415. The dial 416 extends out of the bottom of the sliding box 42. The clamping rod 416 is fixed to one end of the spring 414. The clamping rod 416 can be butted against the lever 431. A docking structure 417 is arranged at the upper end of the sliding box 42;

[0034] The docking structure 417 includes a docking groove 4171. The docking groove 4171 is formed inside the assembling block 47. A second spring 4172 is arranged inside the sliding box 42. A clamping block 4173 is fixed at the end of the second spring 4172. The clamping block 4173 can be butted against the assembling block 47 to limit the assembling block 47. A pressing rod 4174 slidably connected horizontally is assembled inside the sliding box 42. A fixing groove 4175 is arranged at the upper end of the sliding box 42. The assembling block 47 is inserted into the fixing groove 4175. A limiting piece 4176 is arranged on the surface of the pressing rod 4174. A third spring 4177 is arranged inside the sliding box 42, and the third spring 4177 is connected to the limiting piece 4176 for limiting the pressing rod 4174 and for the rebounding effect of the pressing rod 4174;

[0035] When it is necessary to adjust the position of the stretching roller 31, slide the sliding box 42 so that the sliding frame 43 slides along the surface of the fixed rail 41. Since the assembly block 47 is fixed on the sliding box 42, when the sliding box 42 slides, it will drive the assembly block 47 and drive the stretching roller 31 to move its position, so as to achieve the beneficial effect of conveniently adjusting the position of the stretching roller 31. After adjusting the position, the lever 431 can be rotated downward, and then the driving gear 44 will be driven. Because the driving gear 44 is meshed and connected with the driven gear 45, when the driving gear 44 rotates, it will drive the driven gear 45, so that the rotating rod 46 rotates. When the rotating rod 46 rotates, it will drive the rotating plate 461 and make the connecting rod 48 move upward. Since the connecting rod 48 is connected to the sliding groove 411, and the sliding groove 411 is fixed on the side plate 410, when the connecting rod 48 moves upward, it will push the side plate 410 to make the pressing plate 49 move upward and press on the fixed rail 41, so that the sliding frame 43 can no longer slide on the fixed rail 41, so as to achieve the beneficial effect of facilitating limit fixation after sliding adjustment. Reset the lever 431, and the pressing plate 49 will not press on the fixed rail 41, and the limit is released, so as to facilitate later adjustment. After the lever 431 rotates downward, under the action of the spring 414, the latch 415 will be inserted into the lever 431 to limit the lever 431;

[0036] Press the pressure rod 4174 to push the block 4173. The block 4173 will apply force to the second spring 4172. The second spring 4172 is compressed by the force and generates elastic force. Then the assembly block 47 is installed in the fixing groove 4175. At this time, the docking groove 4171 will be docked with the pressure rod 4174. Then release the pressure rod 4174. Under the action of the second spring 4172, the block 4173 will be pushed to dock in the assembly block 47 to limit the assembly block 47, so as to achieve the beneficial effect of conveniently installing and disassembling the assembly block 47, which can make it more convenient when the stretching roller 31 is worn and needs to be disassembled and replaced.

[0037] Please refer to Figure 2 、 Figure 8 and Figure 9 As shown in, the present invention provides a resin softening and stretching device for carbon fiber filament production.

Guide wheels 54 are arranged on the flow splitting block 53. A smoothing structure 55 is arranged at the bottom of the flow splitting block 53;

[0038] The smooth structure 55 includes an adjustment groove 551. The adjustment groove 551 is provided at the top of the installation block 52. The bottom of the shunt block 53 is fixed with an adjustment block 552. The adjustment block 552 is slidably connected to the adjustment groove 551. A press block 553 connected by sliding is assembled inside the adjustment block 552. An abutment plate 554 is integrally formed on the surface of the press block 553. A press rebound device 555 is provided inside the adjustment block 552. The press block 553 is connected to the press rebound device 555. A fourth spring 556 is provided on the surface of the press rebound device 555. A pressing block 557 is provided inside the adjustment block 552.

The fourth spring 556 is located inside the positioning frame 559. And the pressing block 557 is slidably connected along the surface of the positioning frame 559 for positioning the positioning frame 559.

[0039] Put the carbon fibers into the shunt block 53, and put each carbon fiber into a different shunt block 53 respectively. Under the action of the shunt block 53, each carbon fiber will be separated to achieve the separation of the carbon fibers and avoid sticking to each other due to mutual contact. Press the press block 553 and then the press rebound device 555. Under the action of the press rebound device 555, the press block 553 will be pushed and ejected. Then the abutment plate 554 releases the pushing of the pressing block 557. Then the pressing block 557 contracts into the adjustment block 552 under the action of the fourth spring 556. At this time, the pressing block 557 does not press on the inner side of the adjustment groove 551, and the limit on the adjustment block 552 is released. At this time, the shunt block 53 can be slid to make the adjustment block 552 slide along the inner wall of the adjustment groove 551 to achieve the adjustment of the distance between the two shunt blocks 53. Pressing the press block 553 can push the abutment plate 554 to abut on the surface of the pressing block 557, and make the pressing block 557 press on the inner wall of the adjustment groove 551 for limiting.
