[0010] The utility model further sets up: the length of the slurry tank is between 2 times to 3 times of the sizing roller diameter.
[0011] The utility model has the advantages of:

[0013] 2. The infrared instrument in the control assembly can detect the tension of the adjusting wheel in real time, and the change of the tension can be captured immediately when the material roll passes through the adjusting wheel. This real-time feedback can quickly detect tension abnormalities compared with traditional methods relying on manual experience or periodic inspection, ensuring that the carbon fiber is always in the best slitting tension state. The infrared instrument transmits the detected tension data to the controller in a timely manner, and the controller quickly makes a judgment and accurately adjusts the position of the adjusting wheel, improving the stability and reliability of the production process and reducing the rate of defective products caused by unstable tension. The correction round stick in the adjusting wheel assembly is transmission connected with the controller, and when the material roll deviates during the conveying process, the correction round stick can automatically move left and right to correct the material roll, effectively avoiding the cutting position deviation caused by the deviation of the material roll, ensuring the accuracy of the slitted carbon fiber material size and improving the consistency of product quality.
[0014] 3. The sizing assembly adopts a sizing roller design partially immersed in the sizing tank, so that the amount of sizing material taken out by the sizing roller is relatively stable and easy to control. Compared with other sizing methods, the sizing roller can accurately and evenly apply an appropriate amount of sizing material under the material roll, ensuring sufficient wetting of the carbon fiber cutout and avoiding waste or pollution caused by excessive sizing material. By controlling the transmission of the sizing roller with the driving motor and guiding the material roll with several round rods, the sizing roller can stably contact and roll on the lower surface of the material roll, thereby evenly applying sizing material under the material roll.

The fixing plate is uniformly distributed with multiple groups of threaded holes for mounting the tool holder, which can be adjusted by the operator according to different production requirements to meet diversified production needs. When the length of the sizing tank is less than 2 times the diameter of the sizing roller, the reserve of sizing material may be insufficient, affecting production efficiency, and excess sizing liquid may drip onto the rack during the sizing process, causing pollution. When the length of the sizing tank is greater than 3 times the diameter of the sizing roller, the excessively long sizing tank will affect the spatial layout of the entire mechanism and increase the manufacturing cost. Therefore, when the length of the sizing tank is between 2 times and 3 times the diameter of the sizing roller, the sizing tank can reserve an appropriate amount of sizing material to meet the continuous sizing demand of the sizing roller. Appropriate sizing material reserve can maintain the stability of the sizing process and prevent uneven sizing caused by insufficient sizing material supply, thereby ensuring the consistency of carbon fiber sizing quality.

Thus, the exemplary term "lower" can encompass both an orientation of upper and lower. The devices can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0022] Also, the terms "first", "second", and the like, are used herein not necessarily to denote any ordinal, chronological or spatial relationship. Rather, such terms are merely used to distinguish a different constituent from another.
[0023] Figs. 1 to 3 The shown carbon fiber slitting mechanism includes a mounting frame 1, the machine table is provided with a tension adjusting assembly for adjusting the tension of carbon fiber, a cutting assembly and a sizing assembly arranged below the cutting assembly, the tension adjusting assembly includes a first roller 2 and a second roller 3 horizontally and parallel arranged on the mounting frame 1, an adjusting roller 4 arranged below the second roller 3 and a control assembly for controlling the movement of the adjusting roller 4, which can adjust the tension of carbon fiber in real time and accurately. Stable tension can effectively avoid cutting deviation, material deformation and other problems caused by relaxation or over-tightness of carbon fiber during slitting, ensure high precision of slitting size, improve product quality and yield. The cutting assembly includes an adjustable tool holder frame 5, a fixed plate 6 mounted on the tool holder frame 5 and a tool holder 7 fixed on the fixed plate 6. It is convenient to quickly adjust the position and angle of the cutting tool according to different specifications of carbon fiber materials and slitting requirements, realize diversified cutting tasks, the fixed mode of the fixed plate 6 and the tool holder 7 ensures the stability of the cutting tool during cutting, reduces the vibration of the cutting tool, improves the cutting efficiency, reduces the wear of the cutting tool, prolongs the service life of the cutting tool, reduces the production cost, and the sizing assembly arranged below the cutting assembly can perform sizing treatment on the cut immediately after the carbon fiber is slitted. This not only helps to prevent defects such as delamination and burr of the cut, but also enhances the surface performance of the carbon fiber, improves its bonding force with subsequent processing materials, and improves the comprehensive performance and durability of the final product.
[0024] The control assembly includes a controller 8 in transmission connection with the adjusting wheel 4 and an infrared instrument 9 for detecting the tension of the adjusting wheel 4. When the material roll passes through the adjusting wheel 4, the change of the tension can be immediately captured. Compared with the traditional method relying on manual experience or periodic inspection, this real-time feedback can quickly discover tension abnormalities and ensure that the carbon fiber is always in the best slitting tension state. The infrared instrument 9 timely transmits the detected tension data to the controller 8, which quickly makes a judgment and accurately adjusts the position of the adjusting wheel 4. When it is detected that the tension of the material roll is too small, the adjusting wheel 4 is controlled to move downward. When it is detected that the tension of the material roll is too large, the adjusting wheel 4 is controlled to move upward, thereby improving the stability and reliability of the production process and reducing the rate of defective products caused by unstable tension.
[0025] The sizing assembly includes a sizing tank 10 arranged below the knife holder frame 5, a sizing roller 11 arranged on the sizing tank 10, a plurality of round rods 14, and a drive motor 15 for controlling the transmission of the sizing roller 11. The sizing roller 11 is partially in contact with the sizing material, and the upper part of the sizing roller is in contact with the lower surface of the material roll, which uniformly applies the sizing material under the material roll. This makes the amount of sizing material brought out by the sizing roller 11 relatively stable and easy to control. Compared with other sizing methods, the sizing roller 11 can accurately and uniformly apply the appropriate amount of sizing material under the material roll, ensuring sufficient infiltration of the carbon fiber cut and avoiding waste or pollution caused by excessive sizing material. By controlling the transmission of the sizing roller 11 through the drive motor 15 and cooperating with the guiding effect of the plurality of round rods 14, the sizing roller 11 can stably contact and roll on the lower surface of the material roll, thereby uniformly applying the sizing material under the material roll. Uniform sizing helps to improve the consistency of the carbon fiber surface, further enhances the bonding effect with subsequent processing materials, and improves the overall quality of the product.
[0026] The adjusting wheel 4 assembly further includes a correction round rod 12 in transmission connection with the controller 8. When the material roll deviates during transportation, the correction round rod 12 can automatically move left and right to correct the material roll, effectively avoiding cutting position deviation caused by material roll deviation and ensuring the accuracy of the cut carbon fiber material size, thereby improving the consistency of product quality.
[0027] The fixing plate 6 is provided with a plurality of evenly distributed threaded holes 13 for mounting the knife holder 7. The operator can adjust the height of the knife holder 7 according to different production requirements, such as the thickness of the carbon fiber material and the number of layers to be cut, thereby conveniently adjusting the height of the knife holder 7. This flexibility greatly expands the application range of the slitting mechanism, and whether it is a thin carbon fiber sheet or a multi-layer composite carbon fiber plate, accurate slitting can be achieved to meet diversified production needs.
[0028] When the length of the sizing tank 10 is less than 2 times the diameter of the sizing roller 11, the sizing stock may be insufficient, affecting the production efficiency, and during the sizing process, the excess sizing liquid may drip onto the rack, causing pollution; when the length of the sizing tank 10 is greater than 3 times the diameter of the sizing roller 11, the excessively long sizing tank 10 will affect the spatial layout of the entire mechanism, and also increase the manufacturing cost, therefore, when the length of the sizing tank 10 is between 2 times and 3 times the diameter of the sizing roller 11, the sizing tank 10 can store an appropriate amount of sizing stock, meeting the continuous sizing demand of the sizing roller 11, and the appropriate amount of sizing stock can maintain the stability of the sizing process, avoiding the uneven sizing caused by insufficient sizing stock, thereby ensuring the consistency of the sizing quality of the carbon fiber.
