[0013] Beneficial effects:

[0014] 1. Through the conveying frame, connecting plate, limit opening, limit block, conveying plate and conveying device, by starting the servo motor, the servo motor drives the screw rod to rotate, and through the limit opening and the limit block, it has a limiting effect.

[0015] 2. Through the lifting device, electric telescopic rod, bolt column and ball, by starting the electric push rod, the electric push rod extends, driving the support plate and the positioning plate to rise, thereby driving the coiled steel to rise. When the coiled steel rises to the same height as the electric telescopic rod, the electric push rod stops working, adjusts the height of the bolt column, ensures that the ball is attached to the wooden barrel inside the coiled steel, and the electric telescopic rod extends, thereby fixing the coiled steel, and driving the coiled steel to rotate through the feeding device of the laser cutting machine to complete the automatic unwinding work.

[0024] As mentioned in the background technology, in the prior art, laser cutting machines need to manually place rolled steel on an unwinding device when loading. Since the rolled steel is heavy, a large amount of labor cost is consumed, and the existing unwinding device cannot adapt to rolled steel of different specifications, the rolled steel is easily stuck or dropped when rotating, causing a safety hazard. The present disclosure proposes a structure that can automatically load materials and has high applicability.

Electric telescopic rods 2 are fixedly connected to the upper parts of the left and right sides of the unwinding bracket 1. In order to facilitate the placement of rolled steel materials of different specifications, bolt columns 3 are evenly connected to the outer wall of the extended end of the electric telescopic rod 2. The bolt columns 3 are threadedly connected to the extended end of the electric telescopic rod 2. In order to ensure the normal rotation of the rolled steel material, balls 4 are evenly arranged at the ends of the bolt columns 3. The balls 4 are attached to the inner wall of the inner cavity of the rolled steel material, and at the same time ensure that the rolled steel material can rotate normally.

[0027] See also Figure 2 In order to ensure that the coiled steel can be lifted, a lifting device 5 is arranged in the middle of the bottom end surface of the inner cavity of the unwinding bracket 1, and the lifting device 5 is ensured to be in the same plane with the electric telescopic rod 2, so that the coiled steel can be quickly supported by the ball 4 after being lifted. In order to facilitate the delivery of the coiled steel to the upper part of the lifting device 5, a conveying frame 6 is fixedly connected to the middle of the front side of the unwinding bracket 1, and the conveying frame 6 is inclined. In order to ensure the stability of the conveying frame 6, connecting plates 7 are arranged on the upper and lower sides of the inner cavity of the conveying frame 6 to ensure the stability of the left and right structures of the conveying frame 6. A conveying device 9 is arranged on the upper part of the conveying frame 6, and a conveying plate 11 is movably connected to the upper part of the conveying device 9. In order to ensure the stability of the coiled steel, a limiting device is arranged on the upper end surface of the conveying plate 11 to effectively prevent the coiled steel from falling and ensure that the coiled steel is normally transported to the upper part of the lifting device 5.

[0028] See also Figure 2 In order to facilitate lifting the coiled steel to the placement device, a lifting device 5 is composed of a support plate 51, an electric push rod 52 and a positioning plate 53. Two groups of electric push rods 52 with the same structure are evenly fixedly connected in the middle of the bottom end surface of the inner cavity of the unwinding bracket 1, and a support plate 51 is fixedly connected to the upper end surface of the electric push rod 52. In order to ensure that the coiled steel will not fall on the upper end surface of the support plate 51, positioning plates 53 are fixedly connected on both sides of the upper end surface of the support plate 51, which effectively ensures the stability of the coiled steel.

[0029] See also Figure 3In order to facilitate the conveying of the coiled steel to the lifting device 5, it is necessary to transport the conveying plate 11 upward. The conveying device 9 is composed of a moving block 91, a screw rod 92 and a servo motor 93. A servo motor 93 is fixedly connected to the middle of the right end surface of the upper connecting plate 7. The motor shaft of the servo motor 93 extends to the bottom of the upper connecting plate 7 and is fixedly connected to the screw rod 92. The end of the screw rod 92 is movably connected to the right end surface of the lower connecting plate 7. A moving block 91 is sleeved on the outside of the screw rod 92, and the upper end surface of the moving block 91 is fixedly connected to the middle of the lower end surface of the conveying plate 11.

[0030] See also Figure 1 In order to ensure that the conveying plate 11 can move up and down stably, a limit opening 8 is opened on the upper part of the two side plates of the conveying frame 6, and the limit opening 8 is a waist-shaped structure. The limit blocks 10 are fixedly connected to the middle of the left and right end surfaces of the conveying plate 11, and the limit blocks 10 are installed inside the limit openings 8. The thickness of the limit blocks 10 matches the height of the inner cavity of the limit openings 8 to ensure that the movable plate 11 will not tilt and can move up and down stably.

[0031] See also Figure 4 In order to ensure that the rolled steel will not fall or roll due to gravity and shape when being transported to the lifting device 5, a limiting device is formed by a groove 12, a telescopic column 13 and a baffle 14. A groove 12 is opened on the left side of the upper end surface of the conveying plate 11, and the telescopic column 13 is evenly fixedly connected to the bottom end surface of the inner cavity of the groove 12. The baffle 14 is fixedly connected to the upper end surface of the telescopic column 13, and the baffle 14 matches the groove 12 to ensure that the baffle 14 can enter the inner cavity of the groove 12, so that workers can push the rolled steel to the upper end surface of the conveying plate 11.

[0032] Example 2

[0033] See also Figure 2 In order to ensure the stability of the rolled steel on the positioning plate 53, the upper end surface of the positioning plate 53 is arc-shaped, and a rubber pad is fixedly bonded to the upper end surface of the positioning plate 53. The rubber pad has a buffering effect to prevent the rolled steel from having a large collision with the positioning plate 53, thereby preventing the positioning plate 53 from being damaged and easily causing the rolled steel to pop out.

[0034] Working principle: When in use, the staff pushes the rolled steel to the upper end surface of the conveying plate 11, resets it through the telescopic column 13, drives the baffle 14 to move upward, and the baffle 14 blocks the rolled steel from falling. The external power supply is connected to start the servo motor 93, and the servo motor 93 drives the screw rod 92 to rotate. Through the cooperation of the limit opening 8 and the limit block 10, it has a limiting effect. The screw rod 92 rotates to drive the conveying plate 11 to move upward. When the transmission plate 11 moves to the top of the positioning plate 53, the staff pushes the rolled steel, and the rolled steel The steel coil enters the interior of the positioning plate 53, and then the electric push rod 52 is started, which extends to drive the support plate 51 and the positioning plate 53 to rise, thereby driving the steel coil to rise. When the steel coil rises to the same height as the electric telescopic rod 2, the electric push rod 52 stops working, adjusts the height of the bolt column 3, ensures that the ball 4 fits the wooden barrel inside the steel coil, and the electric telescopic rod 2 extends, thereby fixing the steel coil, and drives the steel coil to rotate through the feeding device of the laser cutting machine to complete the automatic unwinding work.
