[0027] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figures 1 to 6 As shown in the figure, a high-performance novel glass fiber cutting device for processing provided by the present invention includes a frame 1, a U-shaped frame 11 fixedly installed on the upper end of the frame 1, movable slots 12 are provided at both ends of the U-shaped frame 11, a moving mechanism 3 is provided on both sides of the U-shaped frame 11, a cutting mechanism 4 is connected to the inner side of the moving mechanism 3, a protective mechanism 2 is provided on the inner side of the U-shaped frame 11, and the cutting mechanism 4 is movably disposed in the protective mechanism 2.

[0031] In this application, the movable groove 12 provides a path for the sliding of the moving mechanism 3. The moving mechanism 3 drives the cutting mechanism 4 to move. When it moves into the protective mechanism 2, the cutting mechanism 4 is protected by the protective mechanism 2. When it moves out of the protective mechanism 2, the glass fiber is cut.

[0032] Furthermore, the moving mechanism 3 includes a fixed base 32, which is disposed on both sides of the U-shaped frame 11. A screw 34 and a slide bar 37 are respectively disposed on the two fixed bases 32. A movable box 36 is movably disposed on the slide bar 37. A moving motor 31 is fixedly installed on the fixed base 32 located on one side of the screw 34. The output end of the moving motor 31 is fixedly connected to the screw 34. A threaded sleeve 33 is threadedly connected to the screw 34. A vibrating seat 35 is fixedly connected to one side of the threaded sleeve 33. The vibrating seat 35 and the movable box 36 are slidably connected in the movable grooves 12 on both sides.

[0033] After the mobile motor 31 starts, it drives the screw 34 to rotate. The screw sleeve 33, which is threadedly connected to the screw 34, drives the vibrating seat 35 to slide in the movable groove 12 on one side. At the same time, the movable box 36 slides on the slide rod 37 and moves in the movable groove 12 on the other side, thereby driving the cutting mechanism 4 to move as a whole. The vibrating seat 35 receives the vibration of the cutter 43 but does not vibrate itself, ensuring stability during the movement process.

[0034] Furthermore, the cutting mechanism 4 includes a vibration motor 41, which is fixedly installed inside the movable box 36. The output end of the vibration motor 41 is fixedly connected to a knife holder 42, and a knife 43 is fixedly installed on the knife holder 42. The end of the knife holder 42 away from the vibration motor 41 is fixedly installed on the vibration seat 35.

[0035] The vibration motor 41 is fixed inside the movable box 36. After starting, it generates vibration and transmits it to the cutter holder 42 and the cutter 43. The cutter 43 moves forward with the moving mechanism 3 while vibrating, thereby cutting the glass fiber during the movement. The vibration cutting method can effectively reduce cutting resistance, improve cutting efficiency, make the glass fiber cross-section flatter, and improve processing quality.

[0036] Furthermore, the protective mechanism 2 includes a fixed cover 21, which is fixedly installed inside the U-shaped frame 11. Guide rods 23 are fixedly connected to both ends inside the fixed cover 21. A protective plate 22 is slidably connected to the guide rods 23. The protective plate 22 covers the outside of the tool holder 42 and the tool 43. A two-way lead screw 24 is rotatably connected to the middle of the fixed cover 21. A lead screw nut 27 is fixedly connected to the middle of the protective plate 22. The lead screw nut 27 is threaded onto the two-way lead screw 24. A gear 25 is fixedly sleeved in the middle of the two-way lead screw 24. A rack 26 is meshed with one side of the gear 25. The rack 26 is fixedly connected to one side of the tool holder 42.

[0037] When the cutter 43 is not working, the fixed cover 21 and the two L-shaped protective plates 22 form a closed space, with the ends of the protective plates 22 abutting each other, enclosing the cutter 43 inside. When working, the moving mechanism 3 drives the cutting mechanism 4 to move forward, and the rack 26 on one side of the cutter holder 42 moves synchronously, driving the gear 25 and the double-acting screw 24 to rotate, so that the two protective plates 22 open, making it easier for the cutter 43 to be removed. After the work is completed, the cutting mechanism 4 resets, the rack 26 drives the double-acting screw 24 to rotate in the opposite direction, the protective plates 22 close, and the closed space is formed again.

[0038] By setting up the L-shaped protective plate 22 and the fixed cover 21, external debris can be effectively prevented from contacting the tool 43, thus avoiding damage to the tool 43. This achieves reliable protection for the tool 43 when it is not in operation, extends the service life of the tool 43, and allows the tool 43 to move freely in and out when it is in operation without affecting its operation.

[0039] Example 2

[0040] Based on Example 1, the functions of waste recycling and fiber detection have been added, as detailed below:

[0041] The waste recycling mechanism includes a negative pressure collection hood (not shown in the figure) located below the frame 1, which is connected to a cyclone separator (not shown in the figure) via a pipe. Glass fiber fragments and short fibers generated during the cutting process are sucked into the collection hood under negative pressure and transported to the cyclone separator for separation. The separated, pure waste can be directly reused as raw material in the melting process, achieving resource recycling and reducing waste disposal costs. Simultaneously, an adjustable damper is installed at the inlet of the collection hood, which can adjust the negative pressure in real time according to the amount of waste generated during cutting, preventing excessive negative pressure from affecting the normal transport of glass fibers.

[0042] The fiber detection module is installed at the feed end of the U-shaped frame 11 and consists of a laser diameter gauge (not shown in the figure) and a tension sensor (not shown in the figure). The laser diameter gauge can detect the diameter of the glass fiber filament in real time. Once the diameter exceeds the set range, it will immediately transmit the signal to the control system. The tension sensor can monitor the tension changes of the fiber during the conveying process. When the tension is abnormal, the control system will adjust the speed of the conveying roller in time to ensure the stability of fiber conveying. The detected diameter and tension data are displayed on the operation panel in real time for easy monitoring by the operator, and the data can be automatically stored to provide a basis for subsequent quality analysis.

[0043] The waste recycling mechanism solves the problem of waste pollution during the cutting process, while the recycled waste reduces raw material costs. The fiber detection module can detect substandard glass fiber filaments in advance, preventing them from entering the cutting process and reducing ineffective processing. Furthermore, the signals from the detection module can be linked to control the cutting mechanism; when a change in filament diameter is detected, the cutting mechanism automatically adjusts the cutting length to ensure consistent product quality. In addition, the purity data of the recycled waste can be fed back to the detection module to optimize detection parameters and further improve the overall performance of the device.

[0044] Furthermore, let:

[0045] The tool movement speed (driven by the moving mechanism 3, unit: mm / s);

[0046] The tool vibration frequency (output by vibration motor 41, unit: Hz);

[0047] The opening range of the protective plate (the displacement of the bidirectional lead screw 24 in the protective mechanism 2, in mm).

[0048] The measured diameter of the glass fiber (output from a laser diameter gauge, unit: μm);

[0049] Fiber tension detection value (tension sensor output, unit: N);

[0050] Negative pressure value for waste recovery (adjustment parameter of the damper in the collection hood, unit: Pa);

[0051] The formula for coordinated control is:

[0052] .

[0053] Coefficient definition:

[0054] : The adaptation coefficient of the protective plate opening amplitude to the tool movement (experimental calibration value, usually taken as 0.8~1.2).

[0055] : Correction factor for fiber diameter on breaking strength (the larger the diameter, the larger the coefficient, ranging from 1.5 to 3.0).

[0056] : Compensation coefficient for tension stability on cutting speed (the larger the tension fluctuation, the smaller the coefficient, ranging from 0.5 to 1.0).

[0057] The influence coefficient of negative pressure on system load (the larger the negative pressure, the larger the coefficient, ranging from 0.3 to 0.6).

[0058] Logical meaning: The left side of the equation represents the "effective cutting power" of the cutter 43 (the synergistic effect of moving speed and vibration frequency); the right side dynamically matches the power of the cutter 43 through the linkage of the opening amplitude of the protective plate 22, fiber diameter, tension, and negative pressure, ensuring:

[0059] 22 opening width of protective board The size increases synchronously with the movement of tool 43. Positive correlation);

[0060] Fiber diameter When increasing the power, the cutoff power needs to be increased ( Positive correlation);

[0061] tension During abnormal fluctuations, reduce power to avoid fiber breakage. (Dynamic compensation)

[0062] negative pressure Excessive power consumption will increase the system load, and the power needs to be reduced to offset the impact. (Reverse association).

[0063] Furthermore, the collaborative extension relationship is as follows:

[0064] Coordination among protective agencies: = ( For the time of travel, (This is the rack-and-pinion transmission ratio coefficient) to ensure that the opening speed of the protective plate matches the movement speed of the cutting tool;

[0065] Waste recycling linkage: (The higher the vibration frequency, the more waste is generated, and the negative pressure increases accordingly.)

[0066] Detection feedback linkage: When When the threshold is exceeded, the system will automatically adjust. And correct Ensure that the cut length is consistent.

[0067] This formula achieves a dynamic balance between "movement-vibration-protection-detection-recovery" by quantifying the synergistic relationship between the parameters of each component.

[0068] Working principle of the invention:

[0069] When it is necessary to cut the glass fiber, the moving motor 31 of the moving mechanism 3 starts, driving the screw 34 to rotate. The screw sleeve 33 drives the vibrating seat 35 to slide in the movable groove 12. The movable box 36 moves synchronously in the slide rod 37 and the movable groove 12 on the other side, thereby driving the cutting mechanism 4 to move forward. At this time, the rack 26 on one side of the cutter holder 42 moves with the cutting mechanism 4, driving the gear 25 to rotate, which in turn causes the bidirectional lead screw 24 to rotate. The bidirectional lead screw 24 drives the two protective plates 22 to open, and the cutter 43 moves from the fixed cover 21 and the protective plate 22 to open. The blade moves out of the enclosed space formed by plate 22. Then, the vibration motor 41 starts, driving the blade holder 42 and the blade 43 to vibrate. Under the combined action of vibration and forward movement, the blade 43 cuts the glass fiber. After the work is completed, the moving mechanism 3 drives the cutting mechanism 4 to reset. The rack 26 moves in the opposite direction with the blade holder 42, causing the gear 25 and the bidirectional lead screw 24 to rotate in the opposite direction. The two protective plates 22 close and their ends abut against each other, forming an enclosed space with the fixed cover 21, enclosing the blade 43 inside, thus protecting the blade 43.

[0070] In summary, this high-performance new type of glass fiber cutting device, by setting up a protective mechanism 2, allows two L-shaped protective plates 22 to close when the tool 43 is not working, forming a closed space with the fixed cover 21. This effectively blocks external debris and protects the tool 43. The plates automatically open during operation without affecting the work, and automatically close after operation, providing reliable protection and extending the service life of the tool 43.
