These embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0020] According to Figure 1 、 2As shown in Figures 3, 4, and 5, in this embodiment, a steel belt guiding and winding device for suture needle transportation is proposed, which includes an L-shaped bottom plate 1 and a winding assembly 2. A winding assembly 2 is provided at one end of the L-shaped bottom plate 1, and a first chute 3 is provided at one end of the side wall of the L-shaped bottom plate 1. There are two groups of the first chutes 3, and a first slider 4 is movably installed inside the first chute 3. A tension adjusting assembly 5 is provided on one side of the first slider 4. A first threaded screw 6 is rotatably installed inside the first chute 3, and the first threaded screw 6 passes through the first slider 4 and is threadedly adapted. A cleaning assembly 7 is provided at the middle position of the L-shaped bottom plate 1. A baffle 8 is provided at one end of one side of the L-shaped bottom plate 1, and second chutes 9 are provided on both the baffle 8 and the other end of the side wall of the L-shaped bottom plate 1. Second sliders 10 are movably installed inside the two groups of second chutes 9, and a pressing wheel 11 is rotatably installed between the two groups of second sliders 10. A support wheel 12 is rotatably installed below between the baffle 8 and the L-shaped bottom plate 1. A pressing groove adapted to the pressing wheel 11 is provided on the support wheel 12. A second threaded screw 13 is rotatably installed inside the second chute 9, and the second threaded screw 13 passes through the second slider 10 and is threadedly adapted. When in use, the steel belt first winds around the limiting wheel 19 of the tension adjusting assembly 5. The first threaded screw 6 rotates to drive the first slider 4 to move inside the first chute 3, adjusting the height of different tension adjusting assemblies 5 and changing the drop during mutual tension adjustment, so that the steel belt winds around the limiting wheel 19 at different height drops. And the third threaded screw 21 rotates to drive the third slider 18 to move inside the third chute 17, changing the position of the limiting wheel 19, thereby changing the spacing of the steel belt winding points to adapt to different tension adjustment requirements. After the tension adjustment, the steel belt passes through the cleaning assembly 7 and reaches between the pressing wheel 11 and the support wheel 12. The second threaded screw 13 rotates to drive the first slider 4 to move inside the first chute 3, and the pressing wheel 11 approaches the support wheel 12 to clamp and press the steel belt.

[0021] The upper end of the first threaded screw 6 penetrates out of the L-shaped bottom plate 1, and a turntable 14 is provided at the upper end of the first threaded screw 6. Rotating the turntable 14 drives the first threaded screw 6 to rotate. A driving motor 15 is provided at the top end of the L-shaped bottom plate 1 far from the turntable 14 and at the top of the baffle 8. The model of the driving motor 15 is YNT-01, and the output ends of the two groups of driving motors 15 are respectively connected to the two groups of second threaded screws 13. The driving motor 15 drives the second threaded screw 13 to rotate.

[0022] The tension adjustment assembly 5 includes a mounting block 16. At the middle position on one side of the mounting block 16, there is a third chute 17. A third slider 18 is movably mounted on the third chute 17, and a limiting wheel 19 is provided on one side of the third slider 18. A limiting groove 20 is provided on the side wall of the limiting wheel 19. The rotation of the third threaded screw 21 drives the third slider 18 to move within the third chute 17, changing the position of the limiting wheel 19, thereby changing the spacing of the steel belt winding points.

[0023] A third threaded screw 21 is rotatably mounted inside the third chute 17. One end of the mounting block 16 is provided with a driving motor 22. The model of the driving motor 22 is ZYT46S-10, and the output end of the driving motor 22 is connected to the third threaded screw 21.

[0025] The winding assembly 2 includes a bracket 28 and a winding roller 29. There are two sets of brackets 28, and a winding roller 29 is rotatably mounted at the upper end between the two sets of brackets 28. A reduction motor 30 is provided at the upper end outside one set of brackets 28. The model of the reduction motor 30 is PDH160312, and the output end of the reduction motor 30 is connected to the winding roller 29. The reduction motor 30 drives the winding roller 29 to rotate to wind up the steel belt.

[0026] Air cylinders 31 are provided at the upper ends on both sides of the two sets of brackets 28, and limit disks 32 are provided at the output ends of the air cylinders 31 on both sides. The winding roller 29 movably passes through the limit disks 32. The air cylinders 31 adjust the spacing between the two limit disks 32 to limit the steel belt. After winding one turn, the two limit disks 32 move to expand the spacing between them, facilitating the regular winding of another turn on the winding roller 29.

[0027] After the steel strip transportation of the steel strip guiding and winding device for suture needles is completed, the tension of the steel strip is adjusted by the tension adjustment assembly 5. The first slider 4 moves in the first chute 3, facilitating the adjustment of the height of different tension adjustment assemblies 5 and changing the drop during mutual tension adjustment, enabling the steel strip to bypass the limit wheel 19 at different height drops. Moreover, the third slider 18 moves in the third chute 17, facilitating the change of the position of the limit wheel 19, thereby changing the spacing of the steel strip winding points to adapt to different tension adjustment requirements. In summary, it is convenient to adjust the tension of the steel strip according to the actual situation, avoiding winding stress inside the steel strip. At the same time, by moving the first slider 4 in the first chute 3, the pressing wheel 11 can be driven to approach the support wheel 12 to clamp and press the steel strip, flattening the surface of the steel strip and avoiding unevenness and other situations to ensure the quality of the steel strip. Additionally, through the action of the cleaning assembly 7, the upper and lower surfaces of the steel strip are cleaned by the cooperation of the two cleaning rollers 25 to avoid the adsorption of dust and debris. Finally, the steel strip is wound by the winding assembly 2. The distance between the two limit discs 32 can be adjusted by the air cylinder 31 to limit the steel strip, ensuring the regularity of winding. After one turn of winding, the limit discs 32 expand the distance between each other, facilitating another regular turn of winding on the winding roller 29 and increasing the winding amount.
