Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a non-woven fabric slitting machine. Background Art

[0002] Non-woven fabric is a non-woven fabric formed by using polymer chips, short fibers or filaments to form a web through airflow or machinery, and then undergoing hydroentanglement, needle punching, or hot rolling reinforcement, and finally post-processing. Because it is not woven, it is also called non-woven fabric. Slitting machine is a mechanical equipment that cuts wide paper, mica tape or film into multiple narrow materials. Non-woven fabric slitting machine is a kind of equipment that trims and cuts wide non-woven fabric materials according to different needs during the production process.

[0003] For example, a non-woven fabric slitting machine disclosed in the utility model with authorization announcement number CN220132643U drives the rectangular sliding cylinder and tooth plate 1 downward by pressing the ball head, and spring 2 is compressed, thereby separating tooth plate 1 and tooth plate 2. The ball head pushes the rectangular sliding cylinder to drive the cutter to move horizontally until the cutter moves to the appropriate position. After releasing the ball head, spring 2 pushes the rectangular sliding cylinder to reset so that tooth plate 1 and tooth plate 2 are engaged, thereby locking the adjusted cutter and realizing rapid adjustment of the cutter.

A plurality of cutting knives 10 are arranged on the inner side of the support frame 1. A fixed shaft is arranged through the side of the cutting knife 10, and the fixed shaft is rotatably connected to the cutting knife 10. A U-shaped plate 9 is arranged outside the fixed shaft, and the fixed shaft penetrates through the U-shaped plate 9 and is fixedly connected to the U-shaped plate 9. A pressing rod 8 is fixedly arranged on the top surface of the U-shaped plate 9. A connecting cylinder 7 is slidably connected to the outside of the pressing rod 8. The pressing rod 8 penetrates through the connecting cylinder 7. A vertical groove is arranged through the inside of the connecting cylinder 7. A first lifting plate 12 is slidably connected to the inner wall of the vertical groove. A first reset spring 11 is fixedly arranged on the bottom surface of the first lifting plate 12. The other end of the first reset spring 11 is fixedly connected to the inner bottom surface of the vertical groove. The bottom surface of the first lifting plate 12 is fixedly connected to the pressing rod 8. The pulling force of the first reset spring 11 on the first lifting plate 12 presses the first lifting plate 12 against the pressing rod 8, so as to press the cutting knife 10 against the rotating roller 2 and avoid the situation of the cutting knife 10 cutting in vain.

[0028] As Figures 1 - 6As shown, a limit assembly is provided above the cutter 10, and the limit assembly consists of a pressure plate 5, a rotating rod 6, a threaded rod 13, a first sliding block 14, a second sliding block 15 and a second return spring 16. A plurality of pressure plates 5 are provided above the fixed box 4, and a rotating rod 6 is fixedly provided on the top surface of the pressure plate 5. A threaded rod 13 is fixedly provided on the bottom surface of the pressure plate 5. The outer side of the threaded rod 13 is threadedly connected to the first sliding block 14. The bottom surface of the first sliding block 14 is fixedly connected to the connecting tube 7. The top surface of the fixed box 4 is provided with a through groove that runs through to the bottom surface, and the through groove is adapted to the first sliding block 14. A sliding block 14 is slidably connected to the fixed box 4 through a through slot. A symmetrical second sliding block 15 is slidably connected inside the first sliding block 14. The second sliding block 15 is a hollow structure. The second sliding blocks 15 are opened on one side close to each other. The front and rear sides of the through slot are connected with symmetrical limiting grooves. The limiting grooves are adapted to the second sliding block 15. The second sliding block 15 is slidably connected to the fixed box 4 through the limiting grooves. A rectangular groove adapted to the second sliding block 15 is provided on the front and rear sides of the first sliding block 14. The second sliding block 15 slides with the first sliding block 14 through the rectangular groove. The second sliding block 15 is connected, and the second sliding block 15 never leaves the rectangular groove during its movement. The top surface of the second sliding block 15 is provided with a hollow groove extending through to the bottom surface. The threaded rod 13 passes through the second sliding block 15 through the hollow groove. The hollow groove can prevent the threaded rod 13 from contacting the second sliding block 15 when rotating and moving up and down. A symmetrical second return spring 16 is fixed between the inner walls of the second sliding blocks 15 on the side close to each other. The rotating rod 6 drives the pressure plate 5 and the threaded rod 13 to rotate relative to the first sliding block 14. The rotation of the threaded rod 13 causes the threaded rod 13 to move upward, thereby The pressing plate 5 is moved away from the top surface of the fixed box 4. The pressing plate 5 is separated from the top surface of the fixed box 4 to release the limit on the cutter 10. The rotating rod 6 is moved left and right to drive the pressing plate 5, the connecting tube 7, the threaded rod 13 and the first sliding block 14 to move left and right to adjust the horizontal position of the cutter 10. When the cutter 10 moves to the specified position, the rotating rod 6 is rotated in the opposite direction until the pressing plate 5 is close to the fixed box 4. The position of the pressing plate 5 relative to the fixed box 4 can be fixed, thereby limiting the position of the cutter 10. The limit assembly has high accuracy in adjusting the position of the cutter 10 and is highly applicable.

[0029] like Figures 1 - 6As shown, a disassembly assembly is provided above the cutter 10, and the disassembly assembly consists of a second lifting plate 17, a connecting rod 18 and a push plate 19. The bottom surface of the second sliding block 15 is hinged with a symmetrical connecting rod 18, and the other end of the connecting rod 18 is hinged with the second lifting plate 17. A sliding groove adapted to the second lifting plate 17 is provided at the bottom of the first sliding block 14. The left and right sides of the second lifting plate 17 are slidably connected to the first sliding block 14 through the sliding groove, and the front and rear sides of the second lifting plate 17 are slidably connected to the inner wall of the through groove respectively. A through hole is provided in the center of the second lifting plate 17, and the threaded rod 13 passes through the second lifting plate 17 through the through hole. The outer diameter of the through hole is slightly larger than the maximum outer diameter of the threaded rod 13. A push plate 19 is fixedly provided on the outside of the threaded rod 13, and the push plate 19 is arranged below the second lifting plate 17. Rotating the rotating rod 6 drives the threaded rod 13 and the push plate 19 to move upward. When the push plate 19 contacts the second lifting plate 17, it drives the second lifting plate 17 to move upward. The movement of the second lifting plate 17 drives the connecting rod 18 to rotate at the same time, and the connecting rod 1 The second sliding block 15 can be moved upward to remove the cutter 10 without removing the fixing box 4, thereby improving the convenience of disassembling and assembling the limit assembly and the cutter 10. The angle of rotating the rotating rod 6 so that the pressure plate 5 is close to the top surface of the fixing box 4 should not exceed 360 degrees. The angle of rotating the rotating rod 6 so that the second sliding block 15 is fully entered into the rectangular groove should be greater than 720 degrees, thereby avoiding the second sliding block 15 from being separated from the fixing box 4 due to accidental touch during the position adjustment of the cutter 10, thereby improving the fault tolerance of the operation.

[0030] Specific working principle:

[0031] When the device is in use, the rotating rod 6 drives the pressure plate 5 and the threaded rod 13 to rotate relative to the first sliding block 14. The rotation of the threaded rod 13 causes the threaded rod 13 to move upward, thereby making the pressure plate 5 away from the top surface of the fixed box 4. The pressure plate 5 is separated from the top surface of the fixed box 4 to release the limit of the cutter 10. The rotating rod 6 moves left and right to drive the pressure plate 5, the connecting tube 7, the threaded rod 13 and the first sliding block 14 to move left and right. The staff adjusts the horizontal position of the cutter 10 as needed. When the cutter 10 moves to the specified position, the rotating rod 6 is rotated in the opposite direction until the pressure plate 5 is close to the fixed box 4. The position of the pressure plate 5 relative to the fixed box 4 can be adjusted. The non-woven fabric is fixed in the row, thereby limiting the position of the cutter 10. The limit assembly has high accuracy in adjusting the position of the cutter 10 and is highly applicable. The staff will pass the non-woven fabric to be cut around the rear rotating roller 3, the rotating roller 2 and the front rotating roller 3 in turn and connect them to the winding roller of the external winder. The external winder is started to make the winding roller pull the non-woven fabric to move. The non-woven fabric is cut when it passes between the cutters 10. The pulling force of the first return spring 11 on the first lifting plate 12 causes the first lifting plate 12 to press the pressure rod 8, thereby causing the cutter 10 to press the rotating roller 2 to avoid empty cutting by the cutter 10.

[0032] When the cutting tool 10 needs to be disassembled, the rotating rod 6 drives the threaded rod 13 and the pushing plate 19 to move upward. When the pushing plate 19 contacts the second lifting plate 17, the second lifting plate 17 moves upward. The movement of the second lifting plate 17 drives the connecting rod 18 to rotate at the same time. The connecting rod 18 rotates and drives the second sliding block 15 to approach each other and completely enter the first sliding block 14. The rotating rod 6 is pulled upward to remove the assembly and disassembly component, which is convenient for directly removing and installing the specified limiting assembly and cutting tool 10 without removing the fixing box 4. The connecting tube 7 can move up and down along the through slot. The height of the connecting tube 7 is slightly longer than the first sliding block 14. When the radius of the cutting tool 10 is large and difficult to pass through the through slot, the first sliding block 14 can be rotated ninety degrees when the first sliding block 14 moves upward to above the top surface of the fixing box 4. The first sliding block 14 can be moved upward to remove the cutting tool 10, thereby improving the convenience of disassembling and assembling the limiting assembly and cutting tool 10.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
