Referring to the attached

drawings

1, 2, 3 and 5, the workbench 2 is provided with a plurality of tightening sliders 14 in a sliding manner, preferably three tightening sliders 14, each tightening slider 14 is located on the inner side of the ring of the rotating disc 8, the upper end of each tightening slider 14 is rotatably provided with a tightening roller 15, the workbench 2 is further provided with a plurality of tightening sliders 16 in a sliding manner, the tightening sliders 16 are located on the inner side of the ring of the rotating disc 8, the tightening sliders 16 correspond to the tightening sliders 14 in a one-to-one manner, and second springs 17 are fixedly connected between the tightening sliders 16 and the tightening sliders 14. And a second connecting rod 18 is connected between each tightening sliding block 16 and the sliding rod 4, two ends of the second connecting rod 18 are respectively hinged with the tightening sliding blocks 16 and the sliding rods 4, and the second connecting rod 18 is always positioned at the lower end of the workbench 2. The slide rod 4 slides up and down in the sleeve 3, the tightening slide block 16 is driven by the second connecting rod 18 to slide on the workbench 2, and the tightening slide seat 14 is driven by the second spring 17 to slide, so that the purpose of adjusting the position of the tightening slide seat 14 is achieved. Before the steel strip coil is ready to be installed, the sliding rod 4 slides downwards, the second connecting rod 18 is used for driving the tightening sliding block 16 to slide towards the direction close to the sleeve 3, the tightening sliding seat 14 is further pulled through the second spring 17 to enable the tightening roller 15 to slide towards the direction close to the sleeve 3, and at the moment, the steel strip coil can be installed. After the installation, slide bar 4 moves upwards, utilize second connecting rod 18 to drive and prop tight slider 16 and to keeping away from sleeve 3 direction and slide, and then promote through second spring 17 and prop tight slide 14, make to prop tight roller 15 and to keeping away from sleeve 3 direction and slide, make and prop tight roller 15 can the butt on steel band book inner wall, prop tight slider 16 this moment and continue to slide, make second spring 17 be in the pulling force state, when the steel band book unreels, prop tight roller 15 and can prop the inner wall of steel band book all the time under the thrust of second spring 17, further prevent that the steel band from curling hair and producing the phenomenon of unreeling.

Referring to fig. 1 and fig. 2, a limiting roller 19 and a steering roller group 20 are rotatably arranged on the working table 2, the distance between the limiting roller 19 and the sleeve 3 is smaller than the distance between the steering roller and the sleeve 3, the steering roller group 20 comprises an upper steering roller 201 and a lower steering roller 202, gears 203 are coaxially fixed on the upper steering roller 201 and the lower steering roller 202, and the two gears 203 are meshed with each other. When unreeling is performed through the limiting roller 19, the unreeling position of the steel strip coil is limited, then the steel strip is converted into a horizontal turntable from a vertical state by using the steering roller group 20, and then the next process is performed, and the upper steering roller 201 and the lower steering roller 202 can be rotated in opposite directions by meshing the two gears 203.

Still be fixed with a plurality of universal wheels 21 that can lock on the base 1, preferably four, lie in the four corners of base 1 respectively, universal wheel 21 can make the convenient removal of whole unreeling machine and can act as transfer device when need not unreeling. When the square roll device needs to be unreeled, the universal wheel 21 is locked, and the square roll device is guaranteed not to move in the unreeling process, so that the stability of the unreeling process is guaranteed.

The working principle of the embodiment is as follows: before the steel strip coil is ready to be installed, the threaded sleeve 302 is rotated according to the thickness of the steel strip coil, and the height of the sleeve 3 is adjusted. After the adjustment is finished, the pressing rod 6 is rotated, the pressing rod 6 drives the pressing roller 7 to be in a vertical state, the sliding rod 4 drives the pressing rod 6 to enter the sleeve 3 under the action of the gravity of the balancing weight 5, and a clamping table on the pressing rod 6 can be clamped at the upper end of the sleeve 3; the sliding rod 4 slides downwards, the abutting sliding block 11 is pushed by the first connecting rod 13 to slide towards one side far away from the sleeve 3, and then the abutting sliding seat 9 is pushed by the first spring 12, so that the abutting roller 10 rotatably arranged on the abutting sliding seat 9 slides towards one side far away from the sleeve 3; when the sliding rod 4 slides downwards, the second connecting rod 18 pulls the tightening slide block 16 to slide to one side close to the sleeve 3, then the second spring 17 is used for pulling the tightening slide block 16, and then the second spring 17 is used for pulling the tightening slide seat 14, so that the tightening roller 15 which is rotatably arranged on the tightening slide seat 14 slides to one side close to the sleeve 3, and then the steel strip coil can be installed.

After the installation is finished, pulling the pressure lever 6 to move upwards, and when the hinged position of the pressure lever 6 and the slide rod 4 is higher than the highest position of the sleeve 3, rotating the pressure lever 6 to enable the compression roller 7 to be compressed on the steel strip coil, and enabling the pressure lever 6 to be clamped on the sleeve 3; when the sliding rod 4 moves upwards, the pressing slide block 11 is driven to slide towards one side close to the sleeve 3 through the first connecting rod 13, and then the pressing slide seat 9 is pulled by the first spring 12, so that the pressing roller 10 is pressed against the outer wall of the steel strip coil. The abutting sliding block 11 continues to slide, and the first spring 12 is in an extension state at the moment; when the sliding rod 4 moves upwards, the second connecting rod 18 drives the tightening slide block 16 to slide towards the side away from the sleeve 3, and then the second spring 17 pushes the tightening slide seat 14, so that the tightening roller 15 abuts against the inner wall of the steel strip coil. The tightening slider 16 continues to slide while the second spring 17 is in a compressed state.

When the unreeling is started, the steel strip roll is in a horizontal state, the unreeled steel strip is in a vertical state, the steel strip enters the steering roller group 20 through the limiting roller 19, the upper steering roller 201 and the lower steering roller 202 rotate oppositely under the action of the gear 203, and the steel strip is changed from the vertical state to the horizontal state. Continuing to unreel, the diameter of steel coil of strip can reduce along with going on unreeling, supports tight slide 9 this moment and makes to support tight roller 10 constantly the butt on the outer wall of steel coil of strip under the pulling force of first spring 12, when the steel coil of strip unreels to the certain extent, the internal diameter of steel coil of strip can the grow, props tight slider 16 and props tight roller 15 constantly the butt on the inner wall of steel coil of strip when under the thrust of second spring 17, until unreeling the completion.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered by the protection scope of the utility model.
