[0026] In the present utility model, the movable rod 13 and the first spring 14 are provided. The connecting plate 7 can be vertically and slidably connected to the moving plate 6 by using the movable rod 13, so that the upper needle device 8 and the connecting plate 7 can automatically adapt to products of different thicknesses by using the movable rod 13, without repeatedly adjusting the parameters of the air cylinder 5, reducing the labor intensity of adjusting the equipment, and using the first spring 14 can stabilize the positions of the connecting plate 7 and the movable rod 13, so that they will not move randomly.

[0027] A clamping groove 12 is provided at the front end of the connecting plate 7, and a clamping plate 11 is provided on the side of the upper needle device 8. The upper needle device 8 is connected to the clamping groove 12 through the clamping plate 11;

[0028] By providing the clamping groove 12 and the clamping plate 11, the upper needle device 8 can be connected to the clamping groove 12 through the clamping plate 11, so as to achieve the purpose of being fixed in the connecting plate 7, and it is convenient to replace the upper needle device 8 with a suitable specification according to the production requirements.

[0029] A locking member 9 is provided in the clamping groove 12. The locking member 9 is used to limit the radial movement of the clamping plate 11. The locking member 9 includes a linkage plate 901, a second spring 904, a pressing rod 902 and a locking rod 903. The linkage plate 901 is arranged under the connecting plate 7 through the second spring 904. The locking rod 903 is arranged at the front end of the linkage plate 901 and penetrates through the connecting plate 7 and extends into the clamping groove 12. The outer side surface of the locking rod 903 is arranged as an inclined surface. The pressing rod 902 is arranged on the linkage plate 901 and penetrates through the connecting plate 7 and is slidably connected thereto;

[0030] By providing the second spring 904 and the locking rod 903, and the outer side of the locking rod 903 is arranged as an inclined surface, when the clamping plate 11 is inserted into the clamping groove 12, the locking rod 903 can be pushed aside, and the back surface of the locking rod 903 is vertically arranged, so that it can stably hold the locking rod 903, and the second spring 904 can apply an upward pulling force to the linkage plate 901, so that the linkage plate 901 can support the locking rod 903 to perform the locking work.

[0031] A threaded groove is provided at a position near the top end of the movable rod 13. The movable rod 13 is connected with a nut 15 through the threaded groove, and the nut 15 is attached to the connecting plate 7;

[0032] By providing the nut 15 and connecting the nut 15 with the threaded groove at the top end of the movable rod 13, the movable rod 13 and the moving plate 6 are detachably arranged. With this arrangement method, when the size of the replaced upper needle device 8 does not match the connecting plate 7, the corresponding specification of the connecting plate 7 can be replaced, further improving the adaptation range of the equipment.

[0033] The first adjusting member 3 includes a slide rail 301, a vertically moving frame 302 and a first threaded rod 303. The slide rail 301 is arranged on the machine base 1. The vertically moving frame 302 is movably connected in the slide rail 301. The first threaded rod 303 is in threaded cooperation with the vertically moving frame 302 and is attached to the machine base 1;

[0034] By setting the first threaded rod 303, when the first threaded rod 303 is in the tightened state, it will move downward and fit on the machine base 1. Correspondingly, an upward supporting force is applied to the vertical moving frame 302, so that the vertical moving frame 302 is closely attached to the top of the slide rail 301. The friction between the two is used to limit and fix the vertical moving frame 302. At the same time, when the first threaded rod 303 is loosened, it will separate from the machine base 1, enabling the vertical moving frame 302 to lose its supporting force, so that its position can be freely adjusted.

[0035] The second adjusting component 4 includes a support rod 401, a second threaded rod 403, and a transverse moving frame 404. The support rod 401 is arranged inside the vertical moving frame 302, and a limiting groove 402 is opened above it. The transverse moving frame 404 is connected to the slide rod 10 and is slidably matched with the support rod 401 through the limiting groove 402. The second threaded rod 403 is in threaded cooperation with the transverse moving frame 404 and is in contact with the support rod 401.

[0036] By setting the limiting groove 402 and the second threaded rod 403, the limiting groove 402 can limit the position of the transverse moving frame 404, enabling the transverse moving frame 404 to freely slide along the support rod 401 but unable to rotate, ensuring the perpendicularity of the transverse support rod 401. When the second threaded rod 403 is in the locked state, it will be in contact with the support rod 401, causing the transverse moving frame 404 to be closely attached to the support rod 401 under the reaction force, achieving the purpose of fixing the transverse moving frame 404.

[0037] Working principle:

[0038] During operation, the air cylinder 5 drives the moving plate 6 to move downward on the side of the slide rod 10. The moving plate 6 drives the connecting plate 7 to move downward through the movable rod 13. The connecting plate 7 drives the upper needle device 8 to fit with the product through the card slot 12 and the clamping plate 11. The upper needle device 8 and the connecting plate 7 stop moving under the support of the product, while the air cylinder 5 drives the moving plate 6 to continue moving. At the same time, the movable rod 13 vertically moves inside the moving plate 6 to offset the subsequent movement of the moving plate 6, enabling the connecting plate 7 and the upper needle device 8 to automatically adapt to products of different thicknesses.

[0039] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
