Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] The properties of carbon fiber determine the types of products. Among these, mechanical properties primarily include tensile strength and tensile modulus. These two properties are determined through carbon fiber multifilament strip testing. The quality of the strips directly impacts the test results, affecting their accuracy and stability. Therefore, strip preparation plays a crucial role in the characterization of carbon fiber, provides guidance for carbon fiber production, and is fundamental to the testing department. Testing requires real-time processing; sampling and testing after the production process wastes time and increases costs. Therefore, testing should be completed during production whenever possible.

[0026] A portable online multifilament test strip preparation machine mainly includes the following steps:

[0027] 1. Wire drawing: Adjust the tension and, under a fixed tension, guide the carbon fiber to the extrusion roller as shown in the diagram;

[0028] 2. Impregnation: Add the prepared resin to the impregnation tank through the feed port according to the specified ratio;

[0029] 3. Resin control: Carbon fibers are impregnated in the impregnation tank, and the resin content is controlled by the resin limiting hole at the outlet;

[0030] 4. Curing: The resin-impregnated filaments are placed in a curing oven for curing to form a sample strip;

[0031] 5. Sample collection: Cut the extruded wire sample into the required length as needed.

[0032] refer to Figure 5 As shown, a portable online multifilament test strip preparation machine has a combination roller installed in the middle position between the guide roller and the impregnation tank, which facilitates the traction of the filament bundle 2 and changes in the traction direction, and makes it easy to unfold and place the portable online multifilament test strip preparation machine.

[0033] refer to Figures 1-2 As shown, a portable online multifilament test strip preparation machine includes a guide roller 1 and a fiber bundle 2. The guide roller 1 is used for feeding, drawing, and outputting the fiber bundle 2, which is a carbon fiber bundle 2. The unimpregnated carbon fiber bundle 2 is elastic and bendable. The fiber bundle 2 is drawn from the guide roller 1, passes through a combination roller, an impregnation tank, a curing oven, and is finally output by an extrusion roller. The mounting base 3 of the combination roller has multiple mounting surfaces. The lower layer is used to install longitudinal rollers, and the upper layer is used to install transverse rollers. The transverse rollers and longitudinal rollers cooperate to draw and change the drawing direction of the fiber bundle 2. Multiple pulleys 303 are installed on the lower end face of the frame 3, which can push the frame 3 to change the position of the combination rollers for more flexible adaptation to the workshop environment. The pulleys 303 can be self-locking to facilitate the fixation of the position of the frame 3. At the same time, lifting components can be installed on the connecting legs between the upper and lower layers of the frame 3.

[0034] A frame 3 is provided along the traction direction of the filament bundle 2. A longitudinal traction assembly is installed on the frame 3. The longitudinal traction assembly includes a pair of first rollers 4, which are longitudinal traction rollers. The rotation directions of the pair of first rollers 4 are opposite, and the gap between the first rollers 4 is matched with the filament bundle 2 to pull the filament bundle 2 to the transverse traction roller on the upper layer of the frame 3. A pair of fixing plates 302 are installed on the frame 3. The fixing plates 302 are mounting angle irons. A motor 5 is installed on the pair of fixing plates 302. A transmission belt 401 is installed on the motor 5. The other end of the transmission belt 401 is installed at the bottom of the first roller 4. The transmission belt 401 cooperates with both the first roller 4 and the motor 5. The motor 5 drives the first roller 4 to rotate through the transmission belt 401.

[0035] refer to Figures 2-3 As shown, a slide rail 301 is installed on the upper layer of the frame 3, and a slider 3011 is installed on the slide rail 301. The slider 3011 can slide inside the slide rail 301. A sliding base 6 is installed on the slider 3011. The slider 3011 and the sliding base 6 are fixedly connected by a bolt assembly. The sliding base 6 can be displaced within the slide rail 301 by the slider 3011 installed on it. By displacing the sliding base 6, the transverse traction roller on it can be displaced synchronously, which is used to change the position of the transverse traction roller relative to the longitudinal traction roller, so as to facilitate the adjustment of the output angle of the filament bundle 2.

[0036] A lateral traction assembly is installed on the slide rail 301 for lateral traction of the carbon fiber bundle 2. The lateral traction assembly includes a deflector and a guide. The deflector and guide adapt the guide wire to the input and deflect it to the output. It also works with the displacement of the slide rail 301 to adapt to more output angles and output directions.

[0037] refer to Figures 3-4As shown, the deflector includes a first fixing frame 601, a second fixing frame 602, a guide plate 603, and a guide shaft 604. The first fixing frame 601 and the second fixing frame 602 are mounted on the sliding base 6. The sliding base 6 has a first mounting groove 6011 that mates with the first fixing frame 601 and a second mounting groove 6021 that mates with the second fixing frame 602. The first fixing frame 601 can be fixedly mounted on the first mounting groove 6011 with mounting bolts, and its position can be changed to position it. The second fixing frame 602 can be fixedly mounted on the second mounting groove 6021 with mounting bolts, and its position can be changed to position it. By changing the mounting positions of the first fixing frame 601 and the second fixing frame 602 on the first mounting groove 6011 and the second mounting groove 6021, and by changing the rotation angle during installation, more input and output angles of the filament bundles 2 can be accommodated.

[0038] A deflectable guide plate 603 is mounted on the first fixed frame 601. The guide plate 603 is connected to the first fixed frame 601 via a shaft and can deflect around the shaft. A guide shaft 604 is mounted on the second fixed frame 602. The guide shaft 604 can follow the second fixed frame 602 by changing its position relative to the second roller 605 by being installed at different positions in the second mounting groove 6021. A first guide rail 6031 is mounted on the guide plate 603. The first guide rail 6031 can deflect synchronously with the deflection of the guide plate 603 to accommodate the input of filament bundles 2 in more directions. A second guide rail 6041 is mounted on the guide shaft 604. By adjusting the installation position of the guide shaft 604 relative to the second roller 605, the guide shaft 604 can lift and lower the end of the second guide rail 6041 that is not in contact with the second roller 605 to control the angle of the filament bundle 2 output, thus outputting the filament bundle 2 into the impregnation tank behind.

[0039] refer to Figures 3-4 As shown, a support roller 606 and a second roller 605 are installed on the sliding base 6. The support roller 606 is located below the second roller 605. The second roller 605 is provided with a plurality of locking grooves that cooperate with the filament bundle 2 to provide sufficient traction force when pulling the filament bundle 2 and cooperate with the first guide rail 6031 and the second guide rail 6041 to force the filament bundle 2 to turn.

[0040] The ends of the first guide rail 6031 and the second guide rail 6041 near the second roller 605 are both located between the second roller 605 and the support roller 606. The ends of the first guide rail 6031 and the second guide rail 6041 near the second roller 605 are both provided with arc-shaped grooves that cooperate with the second roller 605. The filament bundle 2 is conveyed through the first guide rail 6031 to the space between the second roller 605 and the support roller 606. Through the snap-fit ​​groove on the rotating second roller 605, it is pulled onto the second guide rail 6041 and finally output from the second guide rail 6041 with a set deflection angle into the impregnation tank.

[0041] By changing the installation positions of the first fixing bracket 601 and the second fixing bracket 602 installed on the first mounting slot 6011 and the second mounting slot 6021, and adjusting the rotation direction of the guide plate 603 and the guide shaft 604 on them, the deflection angle of the first guide rail 6031 and the second guide rail 6041 is adjusted, ultimately adapting to the input and output of the wire bundle 2 on the guide roller 1 in the workshop.

[0042] In practical use, a combined roller is installed between the guide roller 1 and the impregnation tank in the portable online multifilament test strip preparation machine. Motor 5 is turned on to drive 401, which in turn drives the longitudinal and transverse rollers within the combined roller. Depending on the site conditions, the frame 3 is pushed to an appropriate position, and then the pulley 303 is fixed. The sliding base 6 is pushed along the slide rail 301 to a suitable position. Then, the installation positions of the first fixing frame 601 and the second fixing frame 602 on the sliding base 6 are adjusted on the first mounting groove 6011 and the second mounting groove 6021. The guide plate 603 is flipped to adjust the position of the guide shaft 604 relative to the second roller 605, confirming that the input angle of the first guide rail 6031 matches the angle of the output filament bundle 2 on the first roller 4. The filament bundle 2 is input from the first guide rail 6031 and pulled through the second roller 605 to the second guide rail 6041, where it is output into the impregnation tank.

[0043] Compared with the prior art, the beneficial effect of this utility model is that it adds a movable combination roller to the guide roller of the portable multifilament test strip preparation machine. The combination roller can change the traction angle of the filament bundle and provide sufficient traction force, which can adapt to complex workshop environments and deploy the portable multifilament test strip preparation machine.
