[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5This utility model provides a technical solution: A steel coil packing strap pad includes a pad body 1, the bottom surface of which is arc-shaped, a strip groove 2 formed on the upper end surface of the pad body 1, a rectangular groove 4 formed on the upper end surface of the pad body 1, wedge-shaped surfaces 3 formed at both ends of the strip groove 2, and limit seats 5 formed on both sides of the pad body 1. A negative pressure suction cup 6 is provided below the limit seats 5. The pad body 1 is made of PE material. The strip groove 2 is used to fix the packing strap. When the steel coil is fixed with steel packing strap, the rectangular groove 4 can lock the steel strap in place. The protrusions generated during the deformation locking process partially conceal the gasket. This gasket not only protects the surface of the steel coil from scratches but also provides some protection for subsequent packaging materials, reducing wear and tear on the packaging materials during transportation and storage. Made of PE material, this gasket has sufficient strength and wear resistance. Its smooth surface allows it to fit tightly against the surface of the steel coil, effectively reducing friction between tools and the steel coil. The negative pressure suction cup 6 can fix the gasket body 1 to the surface of the steel coil, serving a pre-positioning function and facilitating the use of packing straps.

[0016] Specifically, such as Figure 3 and Figure 4 As shown, a guide cylinder 7 is provided on the limiting seat 5. The bottom of the guide cylinder 7 is connected to the negative pressure suction cup 6. A piston 10 is provided inside the guide cylinder 7. A guide hole 8 is provided on the side of the guide cylinder 7. A transmission mechanism for controlling the up and down movement of the piston 10 is provided on the side of the limiting seat 5. The transmission mechanism includes an adjusting rod 9 provided on the top of the piston 10. A transmission plate 11 is provided on the top of the adjusting rod 9. A first transmission rod 12 is provided at the end of the transmission plate 11 away from the adjusting rod 9. A positioning seat 13 is provided on the side of the limiting seat 5. A transmission component for driving the first transmission rod 12 is provided on the positioning seat 13.

[0017] Specifically, such as Figure 4 and Figure 5 As shown, the transmission assembly includes a transmission cylinder 14, which is rotatably connected to a positioning seat 13. The inner side of the transmission cylinder 14 is provided with a threaded groove 19, and the outer side of the first transmission rod 12 is provided with a thread. The first transmission rod 12 and the threaded groove 19 are threadedly connected.

[0018] Specifically, such as Figure 3 and Figure 5 As shown, a second transmission rod 16 runs through the gasket body 1, and worm gears 17 are provided at both ends of the second transmission rod 16. A worm wheel 15 is provided at the bottom of the transmission cylinder 14. The worm wheel 15 and the worm gear 17 are meshed and connected. A knob 18 is provided at one end of the second transmission rod 16.

[0019] In summary, the steel coil packing pad provided in this embodiment is used by first placing the pad body 1 on the steel coil, then pressing the pad body 1, which expels the air in the negative pressure suction cup 6. Under the action of the negative pressure suction cup 6, the pad body 1 is fixed on the steel coil. Then, the packing strap is passed through the strip groove 2 to pack the steel coil. When removing the packing strap, turning the knob 18 causes the second transmission rod 16 to drive the two worm gears 17 to rotate. The worm gears 17 drive the transmission cylinder 14 to rotate through the worm wheel 15. Then, the first transmission rod 12 drives the adjusting rod 9 to rise through the transmission plate 11. Then, the piston 10 moves in the air guide cylinder 7. When the piston 10 passes the air guide hole 8, the knob 18 is stopped. At this time, the outside air enters the air guide cylinder 7. Because the negative pressure suction cup 6 and the air guide cylinder 7 are interconnected, the pressure inside and outside the negative pressure suction cup 6 is the same. The pressure is released, and the pad body 1 separates from the steel coil.

[0020] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
