Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric technology, and in particular to a large-size nonwoven fabric cutting device. Background Technology
[0002] Nonwoven fabric is a sheet material that does not undergo traditional spinning and weaving processes. Instead, fibers are directly bonded into a web through physical, chemical, or mechanical means. Nonwoven fabric is usually produced in large rolls and needs to be cut into the specifications required by the customer.
[0003] Patent application publication number CN214879001U discloses a nonwoven fabric cutting mechanism. It includes a support, an input roller, a main cutting device, a side cutting device, and a first conveying mechanism and a second conveying mechanism arranged sequentially along the conveying direction. The input roller is located at the input end of the first conveying mechanism, and the main cutting device is located between the first and second conveying mechanisms. The main cutting device includes a power unit, a cutting blade, and a cutting table. When using this patent, the nonwoven fabric is placed on a first conveyor belt, and a cylinder drives the cutting blade to cut it. However, when using the aforementioned prior art patent, the nonwoven fabric is directly removed after cutting. However, after cutting, the nonwoven fabric edges may become loose and detached, causing small waste particles to float in the air. These small waste particles can enter the equipment, affecting its performance and potentially being inhaled by workers, impacting their health.
[0004] In view of the existing patents, there is a need to provide a large-size nonwoven fabric cutting device with waste edge cleaning function. Utility Model Content
[0005] To overcome the shortcomings of existing patents, which involve directly removing the nonwoven fabric after cutting, resulting in loose and detached fibers at the edges, causing small waste particles to float in the air, enter the equipment, affect its performance, and be inhaled by workers, thus impacting their health, this invention provides a large-size nonwoven fabric cutting device with a waste edge cleaning function.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: A large-size nonwoven fabric cutting device, comprising a mounting frame, a feeding frame, rollers, a cutting machine, a controller, a receiving platform, mounting plates, moving cylinders, friction plates, and a material pulling assembly. The feeding frame is fixedly connected to the mounting frame, rollers are slidably mounted on the mounting frame, the cutting machine is mounted on the feeding frame, the controller is mounted on the mounting frame and electrically connected to the cutting machine, the receiving platform is fixedly connected to the mounting frame, the material pulling assembly is mounted on the mounting frame, two mounting plates are fixedly connected to the mounting frame, two moving cylinders are threaded onto the rollers, two friction plates are mounted on the rollers, and the device further comprises an exhaust fan, moving frames, pneumatic suction nozzles, and a collection box. The collection box is fixedly connected to the mounting frame, two exhaust fans are mounted on the collection box, two pneumatic suction nozzles are connected to the collection box, and two moving frames are slidably mounted on the mounting frame.
[0007] Furthermore, it also includes a first magnetic ring, a first rotating frame, and a pressure roller. Two first magnetic rings are rotatably arranged on the roller, and a first rotating frame is fixedly connected between the two first magnetic rings. A pressure roller is rotatably arranged on the first rotating frame, and the pressure roller contacts the nonwoven fabric to adjust its tension.
[0008] Furthermore, it also includes a second magnetic ring, a second rotating frame, and a flat pleated cylinder. Two second magnetic rings are rotatably mounted on the roller, and a second rotating frame is fixedly connected between the two second magnetic rings. A flat pleated cylinder is rotatably mounted on the second rotating frame.
[0009] Furthermore, the pneumatic nozzle is made of soft rubber.
[0010] Furthermore, the exhaust fan is equipped with a filter.
[0011] Furthermore, a collection frame is installed inside the collection box in a sliding manner.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the exhaust fan to generate negative pressure, the pneumatic suction nozzle is used to adsorb the cut scraps. At the same time, the sliding frame can adjust the position of the pneumatic suction nozzle to ensure that the waste is accurately sucked into the collection frame in the collection box, which is convenient for centralized cleaning. This avoids the formation of dust from fine waste floating in the air and ensures the health of the staff.
[0013] 2. By rotating the first rotating frame, the first rotating frame drives the pressure roller and the first magnetic ring to rotate, and the first magnetic ring is attracted to the roller to fix the angle of the pressure roller, so that the pressure roller presses on the non-woven fabric. This can make the tension of the non-woven fabric more uniform when straightening, and avoid the non-woven fabric from being deformed due to uneven stretching.
[0014] 3. By rotating the second rotating frame, the second rotating frame drives the second magnetic ring and the flat pleating cylinder to adjust the angle, so that the flat pleating cylinder comes into contact with the nonwoven fabric. This allows the pressure roller and the flat pleating cylinder to flatten the nonwoven fabric a second time, eliminating the wrinkles generated in the nonwoven fabric during the conveying process and ensuring cutting accuracy.

[0021] Example 1: A large-size nonwoven fabric cutting device, see reference Figures 1-4As shown, the assembly includes a mounting frame 1, a feeding frame 2, rollers 5, a cutting machine 3, a controller 4, a receiving table 6, a mounting plate 7, a moving cylinder 8, a friction plate 9, and a material pulling assembly 601. The feeding frame 2 is welded to the left side of the mounting frame 1, and rollers 5 are slidably mounted on the left side of the mounting frame 1. Automatic feeding rollers are mounted on the feeding frame 2. The cutting machine 3 is welded to the right side of the feeding frame 2. The controller 4 is welded to the front of the mounting frame 1 and is electrically connected to the cutting machine 3. The receiving table 6 is welded to the right side of the mounting frame 1. The material pulling assembly 601 is located on the right side of the mounting frame 1 and consists of a drive motor, a bracket, and a material pulling roller. The bracket is fixedly connected to the mounting frame 1. The mounting frame 1 is equipped with a drive motor, and a pulling roller is mounted on the output shaft of the drive motor. Mounting plates 7 are fixedly connected to the front and rear sides of the left side of the mounting frame 1. The roller 5 slides on the two mounting plates 7. The left and right sides of the roller 5 are threaded with movable cylinders 8. The left and right sides of the roller 5 are equipped with friction plates 9. The friction plates 9 are located outside the movable cylinders 8 and in contact with them. The mounting frame 1 also includes an exhaust fan 13, a movable frame 14, a pneumatic suction nozzle 15, and a collection box 16. The right side of the mounting frame 1 is fixedly connected to the collection box 1. The top of the collection box 16 is symmetrically equipped with exhaust fans 13. The bottom of the collection box 16 is symmetrically connected with pneumatic suction nozzles 15. The mounting frame 1 is slidably equipped with two movable frames 14. The pneumatic suction nozzles 15 are located in adjacent movable frames 14.
[0022] See Figure 1 and Figure 3 As shown, the pneumatic nozzle 15 is made of soft rubber.
[0023] See Figure 1 As shown, the exhaust fan 13 is equipped with a filter screen.
[0024] See Figure 1 and Figure 3 As shown, a collection frame is slidably installed inside the collection box 16, and the collection frame is connected to the pneumatic suction nozzle 15.
[0025] When this device is needed, first move roller 5 to a suitable position, then screw the moving cylinder 8 onto roller 5 so that friction plate 9 contacts moving cylinder 8 to provide appropriate resistance, thereby fixing roller 5. Then, pull out the nonwoven fabric from the feeding frame 2 and pass it between roller 5 and mounting frame 1, and contact it with the pulling roller on the pulling assembly 601 to straighten the nonwoven fabric. Then, start the pulling assembly 601, drive the motor to rotate the pulling roller, and smoothly pull the cut nonwoven fabric towards the receiving table 6 to ensure continuous feeding. When the non-woven fabric enters the cutting area, the controller 4 starts the cutting machine 3 to cut the non-woven fabric. After cutting, the exhaust fan 13 generates negative pressure, and the pneumatic suction nozzle 15 is used to absorb the cut scraps. At the same time, the sliding frame 14 can adjust the position of the pneumatic suction nozzle 15 to ensure that the waste is accurately sucked into the collection box 16 for centralized cleaning, thereby avoiding the formation of dust from small wastes that float in the air and ensuring the health of the staff. Finally, the cut non-woven fabric is taken out from the receiving table 6.
[0026] Example 2: Based on Example 1, refer to Figure 2 As shown, it also includes a first magnetic ring 10, a first rotating frame 11 and a pressure roller 12. Two first magnetic rings 10 are rotatably arranged on the roller 5. The first rotating frame 11 is fixedly connected between the two first magnetic rings 10. The pressure roller 12 is rotatably arranged on the first rotating frame 11. The pressure roller 12 contacts the nonwoven fabric and adjusts its tension.
[0027] Before cutting, the first rotating frame 11 is rotated, which drives the pressure roller 12 and the first magnetic ring 10 to rotate. The first magnetic ring 10 is attracted to the roller 5, fixing the angle of the pressure roller 12 and driving the pressure roller 12 to press on the non-woven fabric. This makes the tension of the non-woven fabric more uniform when straightening, and avoids the non-woven fabric from being deformed due to uneven stretching.
[0028] See Figure 4 As shown, it also includes a second magnetic ring 17, a second rotating frame 18, and a flat pleating cylinder 19. Two second magnetic rings 17 are rotatably arranged on the roller 5. The second rotating frame 18 is fixedly connected between the two second magnetic rings 17. The flat pleating cylinder 19 is rotatably arranged on the second rotating frame 18. The non-woven fabric is located between the flat pleating cylinder 19 and the pressure roller 12.
[0029] When the pressure roller 12 comes into contact with the nonwoven fabric, the second rotating frame 18 is rotated, which drives the second magnetic ring 17 and the flat pleating cylinder 19 to adjust the angle, so that the flat pleating cylinder 19 comes into contact with the nonwoven fabric. This allows the pressure roller 12 and the flat pleating cylinder 19 to flatten the nonwoven fabric a second time, eliminating the wrinkles generated by the nonwoven fabric during the conveying process and ensuring cutting accuracy.
