Detailed Implementation

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 3 As shown in the figure, this embodiment discloses an unwinding device for sheet metal rolls, including a base 1, a fixed platform 2, a movable platform 4, and a protective plate 6.

[0020] The base 1 is a square metal frame fixed to the ground. The movable platform 4 is slidably connected to the upper part of the base 1. Specifically, the base 1 includes a guide rail 11 located at the top. The lower part of the movable platform 4 is slidably connected to the guide rail 11. A slider 41 is fixed to the lower part of the movable platform 4. The slider 41 is threadedly connected to the lead screw 100 below the base 1. Rotating the lead screw 100 causes the movable platform 4 to slide along the guide rail 11. Limit blocks 12 are fixed at both ends of the guide rail 11. The limit blocks 12 can prevent the movable platform 4 from detaching from the guide rail 11. In this embodiment, the lead screw 100 is rotated by a motor (not shown in the figure). The cooperation structure between the movable platform 4 and the guide rail 11 is existing technology. By rotating the motor forward and backward, the lead screw 100 can be driven to rotate, thereby driving the movable platform 4 to move towards or away from the fixed platform 2. In this way, it is convenient to install the hoisted sheet metal roll 200 on the unwinding device.

[0021] The fixed platform 2 is fixed to the upper part of the base 1. The fixed platform 2 is rotatably connected to the side of the movable platform 4 with a first rotating sleeve 3. The movable platform 4 is rotatably connected to the side of the fixed platform 2 with a second rotating sleeve 5. Specifically, the fixed platform 2 has an adapter sleeve 7 fixed inside. The first rotating sleeve 3 includes a first convex shaft 32, which is inserted into the adapter sleeve 7 and connected to the adapter sleeve 7 through a bearing. The second rotating sleeve 5 includes a second convex shaft 51, which is inserted into the movable platform 4 and connected to the movable platform 4 through a bearing. With the above arrangement, the rotation of the first rotating sleeve 3 and the second rotating sleeve 5 can be realized, thereby facilitating the unwinding of the sheet metal roll 200.

[0022] The second rotating sleeve 5 includes a slot 52 so that the first rotating sleeve 3 can be inserted into the slot 52. Specifically, when it is necessary to install the sheet metal roll 200, the sheet metal roll 200 is first hoisted between the fixed platform 2 and the movable platform 4 by the hoisting equipment. Then, the movable platform 4 slowly moves closer to the fixed platform 2, and the second rotating sleeve 5 is inserted into the center hole of the sheet metal roll 200. The movable platform 4 continues to move, pushing the sheet metal roll 200 closer to the fixed platform 4, and the first rotating sleeve 3 of the fixed platform 4 is inserted into the slot 52. Through the cooperation of the first rotating sleeve 3 and the second rotating sleeve 5, it is not only convenient to unwind the sheet metal roll 200, but also to effectively improve the support capacity of the sheet metal roll 200, greatly reducing the risk of the second rotating sleeve 5 deforming due to long-term pressure. Furthermore, the sheet metal roll 200 can be protected against bursting when blocked by the fixed platform 2 and the movable platform 4.

[0023] The protective plate 6 is fixed to the side of the fixed platform 2. The protective plate 6 is a metal ring structure. Multiple protective rods 61 are fixed on the surface of the protective plate 6 and distributed along its axis. The sheet metal roll 200 is located in the area enclosed by the protective rods 61. The protective rods 61 can play a protective role when the sheet metal roll 200 explodes, reducing the risk.

[0024] The protective plate 6 includes a notch 62, and the distance between the protective rods 61 located at both ends of the notch 62 is greater than the distance between the other adjacent protective rods 61. The strip of the sheet metal roll 200 is unwound and conveyed to the outside through the notch 62.

[0025] The first rotating sleeve 3 includes a first annular plate 31, which is located outside the fixed platform 2. The second rotating sleeve 5 includes a second annular plate 56, which is located outside the movable platform 4. When the sheet metal roll 200 is installed in place, the sheet metal roll 200 is located between the first annular plate 31 and the second annular plate 56. Through the first annular plate 31 and the second annular plate 56, the sheet metal roll 200 can be prevented from contacting the fixed platform 2 or the movable platform 4.

[0026] The second rotating sleeve 5 is connected to a plurality of clamping members 8 on its periphery. The side of the first rotating sleeve 3 can abut against the clamping members 8 and push the clamping members 8 to expand outward. Specifically, the second rotating sleeve 5 includes a plurality of first mounting grooves 53 on the outer surface and second mounting grooves 54 on the inner surface. The first mounting grooves 53 and the second mounting grooves 54 correspond one-to-one and are separated by a partition 55. The clamping member 8 includes a boss 81 and a protrusion 82. The boss 81 can be inserted into the first mounting groove 53. The protrusion 82 passes through the partition 55 and the second mounting groove 54 and is inserted into the slot 52. The end of the protrusion 82 away from the boss 81 is threadedly connected to an arc-shaped block 83. The arc-shaped block 83 is arc-shaped towards the slot 52. A spring 9 is sleeved on the outside of the protrusion 82. The upper end of the spring 9 abuts against the side of the partition 55 facing the second mounting groove 54 and the lower end abuts against the side of the arc-shaped block 83 facing the partition 55.

[0027] like Figure 3 As shown, in order to facilitate the installation of the sheet metal roll 200, the size of the center hole of the sheet metal roll 200 is larger than the diameter of the second rotating sleeve 5. However, this will result in a large gap between the center hole of the sheet metal roll 200 and the second rotating sleeve 5, which is not conducive to the unwinding of the sheet metal roll 200. Therefore, the cooperation between the first rotating sleeve 3 and the clamping member 8 can improve the fixing effect of the sheet metal roll 200, thereby facilitating its unwinding.

[0028] Specifically, before the first rotating sleeve 3 and the clamping member 8 come into contact, the boss 81 is embedded in the first mounting groove 53, and the arc surface of the arc block 83 is located in the slot 52. During the process of inserting the first rotating sleeve 3 into the slot 52, its end will abut against the arc surface of the arc block 83 to push the clamping member 8 to expand outward. When the arc block 83 abuts against the side wall of the first rotating sleeve 3, the boss 81 disengages from the first mounting groove 53 and abuts against the inner wall of the center hole of the sheet metal roll 200, thereby clamping and fixing the sheet metal roll 200, thus realizing the synchronous rotation of the sheet metal roll 200 and the second rotating sleeve 5, which facilitates the unwinding operation of the sheet metal roll 200.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
