DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] In the description of the present invention, it should be noted that the terms "upper", "lower", "middle", "both sides", "horizontal", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] like Figure 1 As shown, the utility model provides a composite needling machine, which includes a frame 1, in which a needle plate 2 for needling fiber filaments is arranged, and a plurality of needles (not shown) are arranged at the bottom of the needle plate 2. A stripping plate 3 capable of pressing down the fiber filaments is arranged below the needle plate 2, and a plurality of needle holes corresponding to the needles are opened on the stripping plate 3 (not shown). A partition 4 is arranged above the needle plate 2 and the stripping plate 3, and the partition 4 is installed on the frame 1, and divides a cavity 5 above the frame 1. A first drive device 6 and a second drive device 7 for driving the needle plate 2 and the stripping plate 3 to move up and down are arranged in the cavity 5, and the partition 4 can prevent the fiber filaments from entering the cavity 5 and thus affecting the operation of the first drive device 6 and the second drive device 7. A movable beam 8 is connected to the top of the needle plate 2, and the first drive device 6 and the second drive device 7 pass through the partition 4 and are connected to the movable beam 8 and the stripping plate 3 respectively. The first driving device 6 is used to drive the needle plate 2 to descend and needle the fiber filaments, and the second driving device 7 drives the stripping plate 3 to strip the fiber filaments on the needle plate 2. A conveying device 9 is arranged below the stripping plate 3, and the conveying device 9 is used to transport the fiber filaments and deliver the fiber filaments to the bottom of the stripping plate 3.

[0021] Furthermore, the first driving device 6 includes a main shaft 10 and a plurality of eccentric wheels 11 arranged on the main shaft 10, each eccentric wheel 11 is connected to a connecting rod 12, and the connecting rod 12 is connected to the movable beam 8. By driving the eccentric wheel 11 to rotate, the eccentric wheel 11 drives the connecting rod 12 to move up and down, so that the needle plate 2 moves up and down. The partition plate 4 is provided with a plurality of first guide sleeves 13, and the first guide sleeve 13 is provided with a guide column 14 that can move up and down in the first guide sleeve 13, and the guide column 14 is connected to the movable beam 8. The guide column 14 moves up and down in the first guide sleeve 13, and can position the linear trajectory of the needle plate 2 moving up and down, so as to prevent the needle plate 2 from being misaligned with the needle hole of the stripping plate 3 after it descends.

[0022] The second driving device 7 includes a main shaft 10 and a plurality of cams 15 arranged on the main shaft 10. A guide rod 16 is arranged below each cam 15. The guide rod 16 is connected to the stripping plate 3. The stripping plate 3 is connected to a spring 20. One end of the spring 20 is connected to the partition 4. The guide rod 16 is driven downward by the cam 15, and the spring 20 is stretched. The guide rod 16 drives the stripping plate 3 to move downward to press the fiber filaments, and then the spring 20 is reset to drive the stripping plate 3 to move upward to return to its original position. A second guide sleeve 17 is arranged on the partition 4. The guide rod 16 is arranged in the second guide sleeve 17 and moves up and down in the second guide sleeve 17 to position the movement of the stripping plate 3 so that the needle 3 of the needle plate 2 can be aligned with the needle hole.

[0023] The stripping plate 3 is U-shaped. When the needle plate 2 descends, the stripping plate 3 will be driven down. The stripping plate 3 is mainly used to stabilize the fiber accumulation, ensure that the fibers can be stably pricked by needles during the needling process, increase the pressure on the fiber, make the needling process more stable, and ensure the integrity and quality of the fibers, thereby achieving higher processing accuracy and effect.

[0024] The conveying device 9 includes a driving roller 18, a driven roller 19, and a net-supporting belt 21 disposed on the driving roller 18 and the driven roller 19, and also includes a plurality of guide rollers 22 disposed below the net-supporting belt 21 for changing the direction of the net-supporting belt 21. The guide rollers 22 increase the internal space of the net-supporting belt 21, which is convenient for collecting waste fibers in the process of needle punching fiber fibers, and can also more conveniently clean the inside of the net-supporting belt 21. The driving roller 18, the driven roller 19, and the guide roller 22 are all provided with a plurality of pins (not shown) corresponding to the meshes (not shown) of the net-supporting belt 17 on the circumference, so as to prevent the net-supporting belt 21 from moving back and forth along the axial direction of the rollers during use, and the pins inserted into the meshes of the net-supporting belt 21 can position the net-supporting belt 21.

[0025] When the utility model is in use, the fiber filaments are transported to the bottom of the stripping plate 3 through the conveying device 9, and the eccentric wheel 11 and the cam 15 drive the connecting rod 12 and the guide rod, so that the connecting rod drives the needle plate 2 and the guide rod drives the stripping plate 3 to make reciprocating motion up and down. When the stripping plate 3 descends, the spring 20 connected to the stripping plate 3 is stretched, the stripping plate 3 presses down the fiber filaments, and the needle plate descends to acupuncture the fiber filaments. Then the needle plate 2 rises, and the spring 5 connected to the stripping plate 3 is reset, and acupuncture is completed. The reciprocating motion of the needle plate 2 and the stripping plate 3 can be realized by driving the eccentric wheel 11, the cam 15 and the main shaft 10, thereby realizing acupuncture of the fiber filaments.
