[0002] An unwinding device for a steel strip drum is a device used to control and place the steel strip drum for processing or use. Such a device is usually used in fields such as steel processing, metal processing, and packaging industries in industrial production. The unwinding device generally includes a stable drum support for supporting the steel strip drum. To maintain the stability and tension of the steel strip drum, the unwinding device is usually equipped with a tensioning device. An advanced unwinding device may be equipped with an automated control system that can achieve automatic control and adjustment of the drum to improve production efficiency and operation convenience.
[0003] In the specific unwinding of the steel strip drum, usually when the steel strip is manufactured, it needs to be wound around the drum and finally sold in rolls. Therefore, the steel strip needs to be unwound before processing, and then when in use, the drum is used to unwind the steel strip. However, when the steel strip is unwound, the tension may change, which may cause the wound steel strip to become loose, thereby affecting the effect of steel strip unwinding and making it inconvenient for the operator to use.

Embodiment
[0026] Refer to Figures 1-4, the present utility model provides a technical solution: an unwinding device for a steel strip reel, including a mounting frame 12, an unwinding mechanism 1 and a motor 2. The unwinding mechanism 1 is a mechanism that can reduce the possibility of slack in the steel strip body 21 during unwinding, thereby improving the unwinding effect of the steel strip body 21. The unwinding mechanism 1 includes a hydraulic cylinder 11, the hydraulic cylinder 11 is fixed to the top of the mounting frame 12, two sets of mounting rods 13 are arranged at the bottom of the hydraulic cylinder 11, mounting discs 14 are arranged on the surfaces of the mounting rods 13, mounting sleeves 15 are arranged on the tops of the mounting discs 14, fixing rods 16 are arranged inside the mounting sleeves 15, springs 17 are arranged on the surfaces of the fixing rods 16, fixing frames 18 are arranged at the bottoms of the mounting sleeves 15, and limiting frames 19 are arranged at the bottoms of the fixing frames 18. Through the mutual cooperation of the hydraulic cylinder 11, the limiting ring 29, the mounting disc 14, the mounting sleeve 15, the limiting frame 19, the spring 17 and the steel strip body 21, when the operator needs to unwind the steel strip body 21, first, the hydraulic cylinder 11 can be controlled to drive the limiting ring 29 to move upward. When the limiting ring 29 moves upward, it drives the mounting disc 14 and the mounting sleeve 15 to move upward synchronously. Then, the coiled steel strip body 21 is sleeved on the steel strip frame 22. Next, the hydraulic cylinder 11 drives the mounting disc 14 and the mounting sleeve 15 to reset downward. The limiting frame 19 moves downward under the action of gravity, and the spring 17 is pressed against the steel strip body 21, so that the steel strip body 21 is always in a compressed state during unwinding, reducing the possibility of slack in the steel strip body 21 during unwinding, thereby improving the unwinding effect of the steel strip body 21.
[0027] Refer to Figures 1-4, in a preferred embodiment, the motor 2 is fixed to one side of the mounting frame 12. A steel belt frame 22 is provided at the output of the motor 2. A limiting block 23 is provided on the surface of the steel belt frame 22. A limiting rod 24 is inserted between the limiting block 23 and the fixed frame 18. The size of the limiting rod 24 on one side of the mounting frame 12 is not equal to the size of the limiting rod 24 on one side of the limiting frame 25. The former is longer and the latter is shorter. Through the above settings, the fixed frame 18 can be limited. A limiting hole 27 is opened on the surface of the mounting plate 14. The mounting rod 13 is inserted into the interior of the limiting hole 27. One end of the spring 17 is fixed to the top of the mounting sleeve 15, and the other end of the spring 17 is fixed to the bottom of the mounting frame 12. A limiting ring 29 is provided at the bottom of the mounting rod 13. The size of the limiting ring 29 is larger than the size of the limiting hole 27. A limiting frame 25 is provided on the surface of the mounting frame 12. Through the mutual cooperation of the hydraulic cylinder 11, the fixed frame 18, the limiting frame 19, the limiting block 23, the limiting rod 24, the limiting block 23 and the anti-slip layer 28, when the operator places the steel belt body 21 in daily use, the operator can control the hydraulic cylinder 11 to drive the fixed frame 18 and the limiting frame 19 to move downward. When moving to be parallel to the limiting block 23, the operator can insert the limiting rod 24 into the interior of the limiting block 23. And an anti-slip layer 28 is provided at the bottom of the limiting frame 19, which can make the placement of the steel belt body 21 more stable, so as to limit the steel belt body 21 for subsequent use.
[0028] Referring to Figures 1-4 , in a preferred embodiment, grooves are opened both inside the limiting frame 25 and inside the mounting frame 12. A sliding rod 26 is provided inside the groove. The fixed frame 18 slides on the surface of the sliding rod 26. By providing the sliding rod 26, the stability of the movement of the fixed frame 18 can be improved. The limiting frame 19 is semicircularly arranged. A steel belt body 21 is provided inside the steel belt frame 22. The size of the limiting frame 19 is adapted to the size of the steel belt body 21. An anti-slip layer 28 is opened at the bottom of the limiting frame 19. By providing the anti-slip layer 28, the placement of the steel belt body 21 can be made more stable.
[0029] Specifically, the working process or working principle of the unwinding device for the steel strip reel is as follows: in the specific unwinding of the steel strip reel, the steel strip usually needs to be wound on the reel during manufacturing and finally sold in a roll. Therefore, the steel strip needs to be unwound before processing. Then, when in use, the steel strip is unwound using the reel. However, when the steel strip is unwound, the tension may change, which may cause the rolled steel strip to become loose, thereby affecting the effect of unwinding the steel strip and making it inconvenient for the operator to use. Therefore, the technical solution can solve the above problem. When the operator needs to unwind the steel strip body 21, the hydraulic cylinder 11 can be controlled to drive the limit ring 29 to move upward. When the limit ring 29 moves upward, it drives the mounting plate 14 and the mounting sleeve 15 to move upward synchronously. Then, the rolled steel strip body 21 is sleeved on the steel strip frame 22, and then The hydraulic cylinder 11 drives the mounting plate 14 and the mounting sleeve 15 to reset downward, and the limit frame 19 moves downward under the action of gravity, and the spring 17 is pressed against the steel belt body 21, so that the steel belt body 21 is always in a compressed state during the unwinding process, reducing the possibility of slackness of the steel belt body 21 during the unwinding process, thereby improving the unwinding effect of the steel belt body 21. When the operator places the steel belt body 21 daily, the operator can control the hydraulic cylinder 11 to drive the fixing frame 18 and the limit frame 19 to move downward. When it moves to be parallel to the limit block 23, the operator can insert the limit rod 24 into the inside of the limit block 23, and the bottom of the limit frame 19 is provided with an anti-slip layer 28, which can make the steel belt body 21 placed more stably, thereby limiting the steel belt body 21 for subsequent use, and all processes are completed here.
[0030] It should be noted that the hydraulic cylinder 11 and the motor 2 are both electrically connected to an external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be implemented in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
