[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4, the utility model provides an embodiment: a steel material unwinding device, including a base 1, the inner wall of the base 1 is slidably connected with a groove cylinder 5, the middle part of the inner wall of the base 1 is fixedly connected with a fixed plate 3, the outer side of the fixed plate 3 is fixedly connected with a hydraulic rod 4, one end of the hydraulic rod 4 is fixedly connected with a disc 7, the front end of the disc 7 is slidably connected with a plurality of rotating plates 8, the front end of the rotating plate 8 is rotatably connected with a clamping rod 6, the clamping rod 6 is rotatably connected to the inner wall of the groove cylinder 5, the middle part of the front end of the disc 7 is rotatably connected with a cylinder 9, the outer side of the cylinder 9 is fixedly connected with a plurality of L-shaped plates 10, the L-shaped plate 10 is engaged with the rotating plate 8, a threaded groove 11 is provided at the front end of the outer wall of the cylinder 9, a spring 12 is fixedly connected to the front end of the cylinder 9, a threaded cover 13 is fixedly connected to the front end of the spring 12, the threaded cover 13 is threadedly connected to the threaded groove 11, and a pressing mechanism 2 is arranged at the top of the base 1;

[0032] Specifically, the threaded cover 13 is pressed, so that the cylinder 9 rotates under the threaded connection between the threaded groove 11 above it and the threaded cover 13, thereby releasing the engagement between the L-shaped plate 10 and the rotating plate 8, and then the hydraulic rod 4 is started to shrink, thereby driving the disc 7 to move toward the rear side of the groove cylinder 5. As the disc 7 moves, the rotating plate 8 will pull the clamping rod 6 to rotate, thereby changing the clamping rod 6 from an expanded state to a contracted state. At this time, the operation of the hydraulic rod 4 is stopped, and the steel strip is rolled into the outside of the groove cylinder 5. At this time, the hydraulic rod 4 is started to extend, driving the disc 7 to move forward, thereby driving the clamping rod 6 to expand through the rotating plate 8, and then the threaded cover 13 is loosened. Under the reset of the spring 12, the cylinder 9 will be driven to rotate, thereby causing the L-shaped plate 10 to engage with the rotating plate 8 again, thereby fixing it to prevent the clamping rod 6 from being accidentally opened.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The pressing mechanism 2 includes a concave hole plate 201, which is fixedly connected to the front side of the top of the base 1, and a sliding block 202 is slidably connected to the inner wall of the concave hole plate 201, and a rack 203 is fixedly connected to the rear side of the sliding block 202. A servo motor 204 is fixedly connected to the rear side of the concave hole plate 201, and a gear 205 is fixedly connected to the output end of the servo motor 204. The gear 205 is meshed with the rack 203, and a pressing column 206 is fixedly connected to the front of the sliding block 202;

[0034] Specifically, after the steel strip roll is placed on the outside of the groove cylinder 5, since the steel strip roll is fixed by a fastening strip, the gear 205 can be driven to rotate by starting the servo motor 204, and the sliding block 202 is driven to move through the meshing connection with the rack 203. As the sliding block 202 moves, the pressing column 206 is driven to move, thereby pressing the steel strip roll to prevent the steel strip from opening instantly when the fastening strip is cut off, causing harm to the staff. When the use of the steel strip roll is reduced at any time, the pressing column 206 will move with it to ensure that it will not be accidentally detached.

[0035] Reference Figure 1 , Figure 2 and Figure 4 A plurality of limiting columns 14 are fixedly connected to the middle of the front side of the groove cylinder 5, and the outer side of the limiting column 14 is slidably connected to the threaded cover 13; a plurality of sliding grooves 15 are opened at the front of the disc 7, and the rotating plate 8 is slidably connected to the sliding grooves 15; an alarm 16 is fixedly connected to the left side of the top of the base 1, and speakers 17 are fixedly connected to the left and right sides of the outer wall of the alarm 16; a first ring 21 is rotatably connected to the front of the base 1, and a second ring 22 is rotatably connected to the outer wall of the groove cylinder 5;

[0036] Specifically, the movement direction of the threaded cover 13 can be restricted by the limit column 14, the movement of the rotating plate 8 can be facilitated by the slide groove 15, the alarm 16 can be used to remind the staff when a fault occurs, the speaker 17 can be used to remind the staff, and the first ring 21 and the second ring 22 can facilitate the feeding of the entire steel strip coil.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The left side of the base 1 is fixedly connected with a controller 18, and the controller 18 is electrically connected to the hydraulic rod 4 and the servo motor 204 respectively; the outer side of the controller 18 is fixedly connected with a housing 19, and the outer side of the housing 19 is rotatably connected with a protective cover 20;

[0038] Specifically, the controller 18 can control the starting and operating power between the hydraulic rod 4 and the servo motor 204 respectively, the housing 19 can prevent the controller 18 from being damaged due to collision, and the protective cover 20 can prevent dust and the like from entering the controller 18 and causing damage to its internal electronic components.

[0039] Working principle: Before using the device, first, it is necessary to apply appropriate pressure to the threaded cover 13 so that it forms an effective threaded connection with the threaded groove 11 above the cylinder 9, thereby causing the cylinder 9 to rotate. This rotation action will cause the engagement state between the L-shaped plate 10 and the rotating plate 8 to be released. Subsequently, the hydraulic rod 4 is started to retract, prompting the disc 7 to move along the rear side of the groove cylinder 5. As the disc 7 moves, the rotating plate 8 will pull the clamping rod 6 to rotate, so that the clamping rod 6 is transformed from an expanded state to a retracted state. After confirming that the clamping rod 6 is fully retracted, the operation of the hydraulic rod 4 is stopped, and the steel strip roll is securely placed on the outside of the groove cylinder 5. Next, the hydraulic rod 4 is restarted to extend, pushing the disc 7 to move forward. This action will drive the clamping rod 6 to expand again through the rotating plate 8. After the clamping rod 6 is fully expanded, release the pressure on the threaded cover 13. At this time, the spring 12 will play a reset role, driving the cylinder 9 to rotate in the opposite direction, so that the L-shaped plate 10 is re-engaged with the rotating plate 8. The movable plate 8 forms a clamping state to ensure the fixation of the clamping rod 6 to prevent it from opening accidentally, and through the pressing mechanism 2, the steel strip roll is securely placed on the outside of the groove cylinder 5. Since it is fixed by the fastening strip, the servo motor 204 is started, and the servo motor 204 drives the gear 205 to rotate, and through the engagement with the rack 203, the sliding block 202 is prompted to move in an orderly manner. As the sliding block 202 moves, the pressing column 206 will move accordingly to apply the necessary pressing force to the steel strip roll. This is intended to prevent the steel strip from opening instantly when the fastening strip is removed, posing a potential safety risk to the staff. At the same time, as the steel strip roll gradually decreases during use, the pressing column 206 will keep moving synchronously to ensure that it will not accidentally disengage under any circumstances, thereby ensuring the safety and stability of the entire operation process. The model of the hydraulic rod 4 is HOB80X250-100, the model of the servo motor 204 is MDME752G1H, and the model of the controller 18 is KC72B30.
