[0039] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0040] like Figure 1 and Figure 2 As shown, a glass fiber cloth cutting device comprises a cutting table 1 and a gantry 2 with a lifting function, wherein the cutting table 1 is located at the lower part of the crossbeam of the gantry 2.

[0041] The cross beam of the gantry 2 is provided with a cutting unit 3 , which includes a fume hood 301 , a slide rail 302 , a laser generator 303 , an air compressor 304 , an air inlet pipe 305 , a cyclone barrel 306 , an exhaust pipe 307 , a debris outlet 308 and a debris collection box 309 .

[0042] The smoke hood 301 is fixed to the bottom of the crossbeam of the gantry 2 , the slide rail 302 is fixed inside the smoke hood 301 , the laser generator 303 is connected to the sliding end of the slide rail 302 , and the laser generator 303 slides inside the smoke hood 301 through the slide rail 302 .

[0043] The air compressor 304 and the cyclone barrel 306 are both fixed on the top of the crossbeam of the gantry 2, the air inlet end of the air compressor 304 is connected to the interior of the smoke hood 301, the air outlet end of the air compressor 304 is connected to the side of the cyclone barrel 306, the air outlet end of the air compressor 304 and the connecting pipeline of the cyclone barrel 306 are provided with a regulating valve 5, the upper part of the cyclone barrel 306 is provided with an exhaust pipe 307, one end of the exhaust pipe 307 leads to the interior of the cyclone barrel 306, the exhaust pipe 307 is connected with the cyclone barrel 306, the lower part of the cyclone barrel 306 is provided with a debris outlet 308, the debris outlet 308 and the cyclone barrel 306 are an integrated structure, the lower part of the debris outlet 308 is provided with a debris collection box 309, the debris collection box 309 and the debris outlet 308 are detachably fixedly connected. The cyclone barrel 306 is a cylindrical structure, the debris outlet 308 is a conical barrel structure, and the inner walls of the cyclone barrel and the debris outlet 308 are both provided with a smooth wear-resistant layer.

[0044] The slide rail 302 in the cutting unit 3 cooperates with the laser generator 303, so that the laser generator 303 can slide inside the fume hood 301, thereby achieving uniform and high-precision cutting of the glass fiber cloth on the cutting table 1. The fume hood 301 forms a negative pressure adsorption effect through the air compressor 304, and quickly absorbs the high-temperature smoke and glass fiber debris generated during the cutting process.

[0045] When the air compressor 304 sucks in the mixed airflow containing smoke and glass fiber debris, a high-speed rotating airflow is formed in the cyclone barrel 306, and the heavier solid particles (such as glass fiber debris) are separated from the airflow by centrifugal force. The cylindrical structure can make the airflow form a regular rotating path in the cyclone barrel 306, improve the separation efficiency, and avoid the separation effect being affected by airflow turbulence.

[0046] The air outlet of the air compressor 304 and the communicating pipe of the cyclone barrel 306 are provided with a regulating valve 5. By adjusting the airflow speed by adjusting the valve 5, a stable and efficient rotating airflow can be formed inside the cyclone barrel 306, so that smoke and glass fiber debris can be fully separated, and the efficiency and accuracy of debris separation can be improved. At the same time, the regulating valve 5 can also flexibly adjust the suction force according to the amount of smoke and debris generated during the cutting process and the characteristics of the debris, so as to avoid the phenomenon of debris backflow or poor adhesion caused by excessive airflow, and ensure the smooth discharge of the debris.

[0047] The debris outlet 308 is configured as a conical barrel structure, which can further concentrate and guide the separated solid particles so that the debris can be smoothly discharged into the debris collection box 309 below. The treated air is discharged into the next treatment process through the exhaust pipe 307, thereby maintaining a clean working environment, preventing smoke and dust from spreading, and reducing the impact on the health of operators.

[0048] At the same time, a smooth wear-resistant layer is provided on the inner wall of the cyclone barrel and the debris outlet 308 to reduce the friction between smoke and glass fiber debris and the inner wall of the cyclone barrel and the debris outlet 308 during the cyclone separation process, thereby reducing the possibility of debris adhering to the inner wall, ensuring that the debris can be discharged smoothly and avoiding blockage. The wear-resistant layer can effectively resist the scouring and wear of the inner wall by solid particles in the high-speed airflow, thereby extending the service life of the cyclone barrel and the debris outlet 308.

[0049] The debris collection box 309 includes a box body 309-1, a placement rod 309-2, a winding rod 309-3, a rotating motor 309-4, an exhibition board 309-5 and a pasting roll 309-6. Antistatic layers are provided on the surfaces of the box body 309-1 and the exhibition board 309-5. The interior of the box body 309-1 is connected to the placement rod 309-2 and the winding rod 309-3. The exterior of the collection box is connected to the rotating motor 309-4. The output end of the rotating motor 309-4 is connected to the winding rod 309-3. The upper part of the collection box is connected to the exhibition board 309-5. The inner core part of the pasting roll 309-6 is detachably connected to the placement rod 309-2. The pasting part of the pasting roll 309-6 passes through the upper part of the exhibition board 309-5, and the pasting surface of the pasting part of the pasting roll 309-6 faces upward. The head end of the pasting part of the pasting roll 309-6 is detachably connected to the winding rod 309-3. The outer edge of the display board 309 - 5 extends downward in an arc shape, and limiting parts are arranged on both sides of the adhesive part of the adhesive roll 309 - 6 on the upper part of the display board 309 - 5 , and the limiting parts are connected to the display board 309 - 5 .

[0050] The adhesive roll 309-6 provided in the debris collection box 309 adheres the debris through the display board 309-5, and the fully adhered adhesive roll 309-6 can be driven by the rotating motor 309-4 to be rolled up, and a new adhesive roll 309-6 is released, which simplifies the debris processing process.

[0051] Among them, the outer edge of the display board 309-5 extends downward in an arc shape, so that the adhesive part of the adhesive roll 309-6 can smoothly transition to the surface of the display board 309-5, reduce the tension concentration phenomenon when the adhesive roll 309-6 is unfolded, and avoid the adhesive performance of the adhesive roll 309-6 to the debris being affected by folding or wrinkling. In addition, the arc structure can reduce the risk of the adhesive roll 309-6 being torn or worn. And the surface of the box body 309-1 and the display board 309-5 are both provided with an antistatic layer, which can effectively prevent the accumulation and interference of static electricity, and prevent glass fiber debris and smoke from adhering to their surfaces due to static adsorption.

[0052] The rotating motor 309-4 is a stepper motor, which can accurately control the rotation position and speed of the reel rod 309-3 through a fine step angle, so as to prevent the adhesive roll 309-6 from being wrinkled or damaged due to excessive or uneven reeling. At the same time, the stepper motor can be started and stopped as needed, effectively reducing energy consumption, and can accurately adjust the reeling force of the adhesive roll 309-6 through preset control, so as to ensure a clear boundary between the debris adhesion part and the unused part, thereby improving the efficiency of debris processing.

[0053] A distance measuring sensor 4 is provided in the box body 309-1, the distance measuring sensor 4 corresponds to the position of the adhesive roll 309-6, and the distance measuring sensor 4 is connected to the box body 309-1.

[0054] The distance measuring sensor 4 corresponds to the position of the adhesive roll 309-6, and can accurately sense the consumption of the adhesive roll 309-6. When the adhesive roll 309-6 is gradually used and close to being exhausted, the distance measuring sensor 4 will capture the information that the adhesive roll 309-6 residual amount is insufficient.

[0055] The fiberglass cloth cutting device further comprises a control panel 6 , which is electrically connected to the gantry 2 , the slide rail 302 , the laser generator 303 , the air compressor, the rotary motor 309 - 4 , the regulating valve 5 and the distance sensor 4 .

[0056] The control panel 6 is connected to the gantry 2, and can accurately control the lifting and lowering action of the gantry 2 to ensure that the cutting unit 3 can reach the optimal cutting position. The control panel 6 is connected to the slide rail 302 and the laser generator 303, so that the control panel 6 can control the precise movement and cutting operation of the laser generator 303, and adjust the cutting trajectory and speed as needed. The control panel 6 is connected to the air compressor 304 and the regulating valve 5, so that the control panel 6 can adjust the operating state of the air compressor 304 and the flow rate of the air outlet in real time, thereby optimizing the suction effect of the smoke hood 301 and the separation efficiency of the cyclone barrel 306. The control panel 6 is connected to the rotating motor 309-4 to control the winding process of the adhesive roll 309-6 in the debris collection box 309, ensuring smooth and efficient cleaning of the debris. The electrical connection between the control panel 6 and the distance sensor 4 can monitor the remaining amount of the adhesive roll 309-6 in real time, so that when the adhesive roll 309-6 is about to run out, an alarm prompt is issued in time, which is convenient for the operator to replace it.

[0057] A glass fiber cloth cutting method comprises the following steps:

[0058] S1: Place the fiberglass cloth to be cut flatly and fix it on the cutting table 1 to ensure that the fiberglass cloth has no wrinkles;

[0059] S2: Start the lifting function of the gantry 2, control the crossbeam of the gantry 2 to move slowly downward until the smoke hood 301 is close to the surface of the glass fiber cloth, and ensure that there is an appropriate gap between the smoke hood 301 and the surface of the glass fiber cloth;

[0060] S3: Start the air compressor 304 to suck the inside of the smoke hood 301;

[0061] S4: Start the slide rail 302 and the laser generator 303, and control the laser generator 303 to move from one end of the slide rail 302 to the other end of the slide rail 302. During this process, the laser generator 303 accurately cuts the glass fiber cloth, and the smoke and debris generated during the cutting process are sucked into the cyclone barrel 306 through the air compressor 304;

[0062] S5: The cyclone barrel 306 separates the smoke and debris, and discharges the large solid particles and glass fiber debris into the debris collection box 309 through the conical debris outlet 308, and at the same time, the treated air is discharged into the next treatment process through the exhaust pipe 307 at the upper part of the cyclone barrel 306;

[0063] S6: The large solid particles and glass fiber debris entering the debris collection box 309 will be partially adhered by the adhesive roll 309 - 6 on the display board 309 - 5 ;

[0064] S7: When a certain amount of debris is accumulated on the adhesive part of the adhesive roll 309-6, the rotating motor 309-4 is started to control the winding rod 309-3 to rotate, and the adhesive roll 309-6 part with the debris is wound on the winding rod 309-3, and at the same time, a new adhesive roll 309-6 part is released to the display board 309-5 for subsequent use;

[0065] S8: The remaining amount of the adhesive roll 309-6 is monitored in real time by the distance measuring sensor 4. When the adhesive roll 309-6 is about to be used up, the control panel 6 sends a prompt signal to remind the operator to replace the adhesive roll 309-6 in time;

[0066] S9: After the cutting operation of the glass fiber cloth is completed, the laser generator 303 and the air compressor 304 are turned off, the lifting function of the gantry 2 is started, and the smoke hood 301 is raised to a safe height;

[0067] S10: removing the cut glass fiber cloth on the cutting table 1.

[0068] The implementation principle of a glass fiber cloth cutting device and a cutting method of the present invention is:

[0069] The present invention forms an efficient smoke and debris adsorption system through the cooperation of the smoke hood 301 and the air compressor 304. During the fiberglass cloth cutting process, the high-temperature smoke and glass fiber debris generated by laser cutting are sucked into the smoke hood 301, and through the negative pressure of the air compressor 304, these pollutants are quickly guided into the cyclone barrel 306 for separation. The high-speed rotating airflow inside the cyclone barrel 306 uses centrifugal force to effectively separate the heavier solid debris from the lighter smoke. The separated smoke is discharged through the exhaust pipe 307 and enters the next processing step, while the solid debris is discharged into the debris collection box 309 through the debris outlet 308. In this way, the working environment can be kept clean, the smoke is effectively controlled, and the health risks to the operators are reduced.

[0070] In order to further improve the efficiency of cleaning the debris, a sticky roll 309-6 is provided inside the debris collection box 309 to cooperate with the display board 309-5. The sticky roll 309-6 laid on the display board 309-5 can automatically adhere to the collected glass fiber debris. When enough debris accumulates on the surface of the sticky roll 309-6, the rotating motor 309-4 drives the winding rod 309-3 to perform the winding operation, and the part with the debris adhered is wound on the winding rod 309-3, and a new sticky roll 309-6 part is released to continue the cleaning of the debris. This not only greatly simplifies the cleaning process of the debris, but also improves the operating efficiency, avoids the tediousness of manually cleaning the debris, and ensures the continuity and smoothness of the operation.

[0071] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
