[0022] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] The terms "top surface", "bottom surface" and "underside" are based on the normal use state of the unwinder and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] like Figure 1 and 2 As shown, a uncoiler with a coil support function includes a machine body 1; a roller frame 5, which is arranged on the machine body 1 and is used to support the coil after unwinding, and the forward direction of the coil is a first direction. The roller frame 5 includes two oppositely arranged side plates 505 and a support roller 501 that is rolled between the two side plates 505, and the support roller 501 is horizontally arranged perpendicular to the first direction; a clamping mechanism 6 includes an upper clamping part 602 and a lower clamping part 506 that are relatively slidable, and the lower clamping part 506 is fixedly connected between the two side plates 505, and the upper clamping part 602 is slidably connected to the side plates 505, and the coil passes between the upper clamping part 602 and the lower clamping part 506.

[0025] When the above-mentioned unwinding machine is used for unwinding metal sheets, the material coil is placed on the machine body 1 for unwinding. The unwinded coil passes over the roller frame 5 and is supported by the roller frame 5 from below. The supporting force of the roller frame 5 can offset part of the gravity of the coil, thereby reducing the force of the coil acting on the unwinding machine, so that the unwinding machine can effectively control the unwinding of the coil under a smaller load, thereby reducing the energy consumption of the unwinding machine and improving the energy-saving performance of the unwinding machine; the coil passes between the upper clamping part 602 and the lower clamping part 506 of the clamping mechanism 6. When the coil is unwound to the end, it is difficult for the coil to continue to be wound on the unwinding machine and it is easy to slip off the unwinding machine. At this time, the unwinding machine can be manually controlled to make the upper clamping part 602 and the lower clamping part 506 close to each other, thereby clamping the end of the coil to prevent the coil from falling directly to the ground under the action of its own weight when it falls off the unwinding machine. This not only reduces the chance of damage to the coil, but also improves the safety of the unwinding machine.

[0026] The roller frame 5 has two side plates 505, and a plurality of support rollers 501 are arranged between the two side plates 505 at equal intervals along the first direction. The support rollers 501 are set to support the coiled material. At the same time, the rolling friction between the support rollers 501 and the coiled material is used to reduce the resistance of the coiled material when it moves forward, reduce energy loss, and improve the energy-saving effect of the equipment; the upper clamping part 602 and the lower clamping part 506 are made of rubber material, which can increase the friction force between the upper clamping part 602 and the lower clamping part 506, and at the same time reduce the probability of the upper clamping part 602 and the lower clamping part 506 scratching the coiled material.

[0027] Further improvements are, Figure 1-3 As shown, the roller frame 5 is slidably connected to the machine body 1 along a first direction. The machine body 1 is fixedly connected to a track 2 extending along the first direction. A movable trolley 3 is provided on the track 2. The movable trolley 3 is provided with a support frame 301. The roller frame 5 is rotatably provided on the support frame 301. The movable trolley 3 has movable wheels, and a motor is installed inside the movable wheels to drive the movable wheels to rotate. The movable wheels match the track 2. Through the rotation of the movable wheels, the movable trolley 3 can be driven to move along the track 2 as a whole, thereby causing the roller frame 5 and the clamping mechanism 6 to move along the forward direction of the unwinding coil. Through the movement of the roller frame 5, the position of the roller frame 5 supporting the coil can be adjusted so that the roller frame 5 supports the middle position of the coil, thereby improving the support effect of the roller frame 5 on the coil. At the same time, when the clamping mechanism 6 clamps and fixes the end of the coil, the movement of the clamping mechanism 6 can drive the coil forward to realize the conveyance of the coil, thereby realizing the complete unwinding process of the coil, improving the convenience and work efficiency of the unwinder.

[0028] Further improvements are, Figure 2-4 As shown, a rotating shaft 502 is fixedly connected between the two side plates 505 perpendicular to the first direction. A rotating sleeve 304 is sleeved on the outer periphery of the rotating shaft 502, which is fixedly connected to the support frame 301. A thrust member 4 is hingedly connected between the support frame 301 and the roller frame 5, which is used to drive the roller frame 5 to rotate. In the above-mentioned unwinding machine, the rotating sleeve 304 is provided on the support frame 301, and is used to fix the rotating shaft 502 and enable the rotating shaft 502 to rotate about its own axis. This allows the entire roller frame 5 to rotate, thereby adjusting the angle of the roller frame 5, so that the roller frame 5 can better fit the bottom of the coil and improve the support effect of the roller frame 5 on the coil. The thrust member 4 is a hydraulic cylinder, one end of which is hinged to the support frame 301 and the other end is hinged to the side plate 505. In this way, the extension and contraction of the hydraulic cylinder can drive the roller frame 5 to swing about the rotating shaft 502, thereby adjusting the angle of the roller frame 5.

[0029] Further improvements are, Figure 4As shown, the lower clamping portion 506 is fixedly connected to the rotating shaft 502. In the above unwinding machine, the upper clamping portion 602 moves along the radial direction of the rotating shaft 502. During the rotation of the roller frame 5, the upper clamping portion 602 can always move in the direction toward the lower clamping portion 506, thereby improving the clamping effect of the upper clamping portion 602 and the lower clamping portion 506 on the coiled material. In addition, the rotating shaft 502 is directly connected to the support frame 301 through the rotating sleeve 304, and the lower clamping portion 506 is fixed to the rotating shaft 502, which can improve the secure installation of the lower clamping portion 506 and further enhance the clamping effect on the coiled material.

[0030] Further improvements are, Figure 3 As shown, the support frame 301 is fixedly connected to a vertically distributed guide tube 302. A lifting column 303, coaxially slidably engaged within the guide tube 302 and fixedly connected to the rotating sleeve 304, is provided. A thrust member 4 is provided on each side of the rotating shaft 502. The guide tube 302 acts as a limiter for the lifting column 303, allowing it to rise and fall freely, thereby enabling the roller frame 5 to be raised and lowered. This allows the roller frame 5 to support coils of varying heights, improving its support for the coils. During operation, two hydraulic cylinders are arranged opposite each other at the front and rear sides of the rotating shaft 502 along a first direction. When the two hydraulic cylinders rise and fall synchronously, they drive the roller frame 5 to rise and fall. When one hydraulic cylinder extends and the other contracts, the two hydraulic cylinders drive the roller frame 5 to rotate about the rotating shaft 502, thereby achieving both the rise and fall of the roller frame 5 and improving its support for the coils.

[0031] Further improvements are, Figure 2 、 4 As shown in Figure 5, the upper clamping part 602 is arranged above the roller frame 5, and the side plate 505 is fixedly connected with a guide sleeve 503 distributed along the sliding direction of the upper clamping part 602. The guide sleeve 503 is coaxially slidably fitted with a guide column 603 inside the guide sleeve 503. The guide column 603 is fixedly connected to the upper clamping part 602, and a power part is arranged between the upper clamping part 602 and the side plate 505; the power part includes a magnetic attraction part 601 fixedly connected to the upper clamping part 602, an electromagnet 504 fixedly connected to the side plate 505 and a spring 604 sleeved on the outer periphery of the guide column 603, and the two ends of the spring 604 are respectively connected to the guide sleeve 503 and the guide column 603. In the above-mentioned unwinding machine, the guide sleeve 503 and the guide column 603 cooperate to realize the guiding and limiting effect on the upper clamping part 602, thereby improving the stability of the upper clamping part 602. The magnetic part 601 is a metal block that can be adsorbed by the electromagnet 504. When the upper clamping part 602 and the lower clamping part 506 need to be clamped, the energized electromagnet 504 adsorbs the magnetic part 601, and the two are close to each other to achieve clamping and fixing of the coil; when the electromagnet 504 is powered off, the spring 604 drives the upper clamping part 602 to reset, so that the upper clamping part 602 and the lower clamping part 506 release the coil.
