[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 3The diagram shows a needle plate rack for nonwoven fabric production, comprising a placement platform 1 and a positioning platform. The positioning platform is located at the center of the placement platform 1 and consists of an upper adjustment platform 3 and a lower auxiliary platform 2. The adjustment platform 3 contains a positioning assembly, which includes a rotating disk 31, two fixed connecting rods 4, two movable connecting rods 5, and four push plates 6. The rotating disk 31 is rotatably mounted inside the adjustment platform 3, and a rotating shaft 33 is located at the center of the rotating disk 31. The rotating shaft 33 is connected to a motor 34. The rotating disk 31 has four arc-shaped slide rails 32. The two fixed connecting rods 4 are respectively located on a pair of opposite sides of the adjustment platform 3. All connecting rods 4 are slidably inserted into the adjusting platform 3. The insertion end of the fixed connecting rod 4 is provided with a vertical connecting post 7. Two push plates 6 are fixedly installed on the outer ends of the two fixed connecting rods 4. The vertical connecting post 7 is slidably inserted into the corresponding arc-shaped slide rail 32. The two movable connecting rods 5 are symmetrically and slidably inserted into another set of opposite sides of the adjusting platform 3. The movable connecting rod 5 is provided with multiple mounting slots 51. The other two push plates 6 are detachably installed on the movable connecting rod 5. The push plates 6 are detachably installed on the movable connecting rod 5 through the mounting slots 51. The insertion end of the movable connecting rod 5 is also slidably inserted into the corresponding arc-shaped slide rail 32 through the vertical connecting post 7. Generally, since the needle plate 10 is usually rectangular, the length of the fixed connecting rod 4 is less than the total length of the movable connecting rod 5. When placing it, the long side of the needle plate 10 is placed on the upper side of the fixed connecting rod 4, and the short side of the needle plate 10 is located above the movable connecting rod 5. When using it, first reinstall the position of the push plate 6 on the movable connecting rod 5 according to the length of the needle plate 10. Note that the two push plates 6 on the movable connecting rod 5 should be symmetrical to each other, and the distance between the two push plates 6 should be equal to the length of the long side of the needle plate 10. Then start the motor 34, the rotating disk 31 will rotate, and the fixed connecting rod 4 and the movable connecting rod 5 will converge inward to fix the needle plate 10. Since the position of each push plate 6 has been adjusted in advance, even if the needle plate 10 is not placed in the center of the placement table 1 when it is placed, it will return to the center of the placement table 1 under the action of the four push plates 6 to achieve positioning.

[0018] The adjustment platform 3 is provided with connecting ports around its four sides. The auxiliary platform 2 is provided with slide rails 21 on the platform surface corresponding to the four connecting ports. The fixed connecting rod 4 and the movable connecting rod 5 are slidably arranged in the slide rails 21.

[0019] The fixed connecting rod 4 and the movable connecting rod 5 are inserted into the adjusting platform 3 through a communication port, as shown in the figure. Both the fixed connecting rod and the movable connecting rod are slidably located below the rotating disk.

[0020] The mounting slot 51 is equipped with a magnetic block, and the corresponding push plate 6 is also equipped with a magnetic block, which facilitates the quick installation of the push plate 10.

[0021] The top surface of the push plate 6 is higher than the top surface of the adjustment table 3. The needle plate 10 needs to be placed on the adjustment table 3, so the height of the push plate 6 must be higher than the height of the adjustment table 3 in order to hold the needle plate 10.

[0022] The bottom of the placement platform 1 is provided with a support column 11, and the motor 34 is located inside the auxiliary platform 2.
