[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] like Figures 1 to 5As shown, the present invention proposes a non-woven fabric reinforcement needle punching device, including a mounting plate 1. Supports 24 are provided on both the left and right sides of the mounting plate 1, and the mounting plate 1 is fixedly connected to the supports 24. The supports 24 facilitate the installation of the equipment. A motor 2 is provided on the rear side of the mounting plate 1, and the rear side of the mounting plate 1 is fixedly connected to the front side of the motor 2. The output end of the motor 2 extends through to the front side of the mounting plate 1 and is provided with a turntable 3. The output end of the motor 2 is fixedly connected to the turntable 3. The front side of the mounting plate 1 is open... An L-shaped groove is provided, and an L-shaped ring 25 is provided on the rear side of the turntable 3. The rear side of the turntable 3 is fixedly connected to the front side of the L-shaped ring 25. The L-shaped ring 25 is rotatably connected to the L-shaped groove. The L-shaped ring groove can guide and limit the L-shaped ring 25, thereby guiding and limiting the running trajectory of the turntable 3. An adjustment groove is provided on the front side of the turntable 3. A knob 4 is rotatably provided on the top of the turntable 3. A screw 5 is provided on the bottom surface of the knob 4. The bottom surface of the knob 4 is fixedly connected to the top surface of the screw 5.

[0023] The bottom end of the screw 5 extends through the interior of the adjustment groove and is threadedly connected to a threaded block 6. The bottom end of the screw 5 is rotatably connected to the bottom end of the adjustment groove, which facilitates the support and fixation of the bottom end of the screw 5. The outer wall of the threaded block 6 is in contact with the inner wall of the adjustment groove and is slidably connected. The adjustment groove can guide and limit the running trajectory of the threaded block 6. Rotating the knob 4 can drive the screw 5 to rotate. The rotation of the screw 5 can drive the threaded block 6 to move up and down along the screw 5. A rotating plate 7 is provided on the front side of the threaded block 6. The front side of the threaded block 6 is fixedly connected to the rear side of the rotating plate 7. A guide groove 8 is provided on the front side of the rotating plate 7. A cylindrical block 9 is slidably arranged inside the guide groove 8. When the threaded block 6 is located at the middle position of the screw 5, the cylindrical block 9 remains unchanged when the rotating plate 7 rotates. When the threaded block 6 moves down or up, it will drive the cylindrical block 9 further and further away from the output shaft of the turntable 3, thereby adjusting the size of the reciprocating distance and thus adjusting the needle penetration depth.

[0024] A connecting rod 10 is provided around the outer ring of the cylindrical block 9, and the outer ring of the cylindrical block 9 is fixedly connected to the connecting rod 10. A connecting plate 11 is provided on the bottom surface of the mounting plate 1, and the bottom surface of the mounting plate 1 is fixedly connected to the top surface of the connecting plate 11. A rectangular plate 12 is provided on the front side of the connecting plate 11, and the front side of the connecting plate 11 is fixedly connected to the rear side of the rectangular plate 12. A C-shaped block 13 is provided on the front side of the rectangular plate 12, and the front side of the rectangular plate 12 is fixedly connected to the rear side of the C-shaped block 13. The outer wall of the connecting rod 10 is connected to the inner wall of the C-shaped block 13. The connecting rod 10 is slidably connected and guided and limited by the C-block 13. The bottom end of the connecting rod 10 is provided with a mounting block 14, and the bottom end of the connecting rod 10 is fixedly connected to the top surface of the mounting block 14. When the rotating plate 7 rotates, it will drive the guide groove 8 to rotate. The rotation of the guide groove 8 can drive the cylindrical block 9 to slide inside the guide groove 8. Since the rotating plate 7 is located at the eccentric position of the output shaft of the turntable 3, it can drive the connecting rod 10 to move up and down, thereby driving the mounting block 14 to move up and down.

[0025] The top surface of the mounting block 14 has two movable slots, each with a receiving groove on its bottom surface. Each receiving groove also has a movable slot on its bottom surface. A guide rod 15 is installed inside each receiving groove, and the guide rod 15 is fixedly installed within the receiving groove. A slider 16 is slidably mounted on the side of each guide rod 15 that is close to each other, and the slider 16 is slidably connected to the receiving groove. A spring 17 is fitted around the outer ring of the side of each guide rod 15 that is far apart from each other. The guide rod 15, slider 16, and spring 17 are all located in corresponding positions. Inside the receiving groove, each slider 16 has a connecting block 18 on its top surface. The top surface of the slider 16 is fixedly connected to the bottom surface of the connecting block 18. The connecting block 18 is slidably connected to the movable groove 1. Each connecting block 18 has a toggle block 19 on its top surface. The top surface of the connecting block 18 is fixedly connected to the bottom surface of the toggle block 19. Each slider 16 has a connecting block 20 on its bottom surface. The bottom surface of the slider 16 is fixedly connected to the top surface of the connecting block 20. The connecting block 20 is slidably connected to the movable groove 2.

[0026] The connecting block 20 and each set of locking strips 23 are slidably connected on the side close to each other. Each connecting block 20 has a locking block 21 on its bottom surface. The bottom surface of the connecting block 20 and the top surface of the locking block 21 are fixedly connected. The bottom surface of the mounting block 14 is provided with a needle plate 22. The bottom surface of the mounting block 14 is in contact with the top surface of the needle plate 22 but not fixedly connected. The top surface of the needle plate 22 has two slots. Each of the two slots has a set of locking strips 23 on the side close to each other. The locking strips 23 are fixedly installed inside the slots. Each locking block 21 is slidably connected to the corresponding slot. The top surface of the locking block 21 is in contact with the bottom surface of the locking strip 23. The locking strips 23 can limit the locking block 21 to ensure a stable connection between the mounting block 14 and the needle plate 22.

[0027] In this embodiment, when using this device, if the needle plate 22 needs to be replaced, the two levers 19 need to be moved to a side away from each other. This causes the two levers 19 to move the connecting block 18, slider 16, connecting block 20, and locking block 21 in a direction away from each other. This moves the locking block 21 to a position in the slot where the locking strip 23 is not limiting it, thus separating the mounting block 14 from the needle plate 22. Then, the new needle plate 22 is placed below the mounting block 14, the locking block 21 is installed into the slot, and the force on the levers 19 is released. This causes the spring 17 to push the slider 16 back to its original position, allowing the locking block 21 to move into the slot and be limited by the locking strip 23. The position ensures the stability of the connection between the mounting block 14 and the needle plate 22. When it is necessary to adjust the needle depth, the knob 4 can be turned. The rotation of the knob 4 drives the screw 5 to rotate. The rotation of the screw 5 can drive the threaded block 6 to move up and down along the screw 5, thereby driving the rotating plate 7 to move to the eccentric position, thereby increasing the reciprocating travel distance. Then, the motor 2 is run, which can drive the turntable 3 to rotate, thereby driving the rotating plate 7 to rotate. The rotation of the rotating plate 7 can drive the cylindrical block 9 to slide inside the guide groove 8, thereby causing the connecting rod 10 to reciprocate up and down, thereby driving the mounting block 14 to reciprocate up and down.

[0028] The above-described specific embodiments are merely preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
