[0024] 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.

[0025] 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.

[0026] like Figure 1 and 2 As shown, a reeling machine with a fast loading function includes a body 1 equipped with an unwinding shaft 2, a movable trolley 4 is provided on the body 1 for horizontal movement, and a support mechanism 5 is provided on the top of the movable trolley 4 for lifting and lowering; the support mechanism 5 includes a base plate 501 and a plurality of support rollers 504 distributed along the axial direction of the unwinding shaft 2, and each support roller 504 is arranged at equal intervals perpendicular to its own axial direction directly above the base plate 501, and both ends of the support roller 504 are connected to the base plate 501 by elastic connecting parts.

[0027] The above-mentioned unwinding machine is suitable for but not limited to the unwinding operation of metal sheets. When in use, the coil is hoisted onto the support mechanism 5, and the coil is transported to the unwinding shaft 2 by the mobile trolley 4. Then the support mechanism 5 is raised and lowered to make the coil dock with the unwinding shaft 2. The unwinding shaft 2 is an inflatable shaft. By inflating the unwinding shaft 2 to make it expand, the unwinding shaft 2 and the coil are fixed to each other. At this time, the support mechanism 5 stays under the coil to support the coil. After the coil is unwound, the mobile trolley 4 drives the support mechanism 5 to reset, so that a new coil can be placed on the support mechanism 5.

[0028] Compared with the existing unwinding machine in which a support device is provided to support the other end of the unwinding shaft 2, the support mechanism 5 of the unwinding machine can play the role of transporting the coil and supporting the coil. During the unwinding process, it can effectively support the unwinding shaft 2 and the coil, thereby improving the stability of the unwinding machine operation; at the same time, it eliminates the need for the setting of additional support devices, reducing the production cost of the unwinding machine; and during the loading process, it eliminates the time for retracting and extending the additional support device, as well as the time for resetting the mobile trolley 4, which greatly improves the loading efficiency of the unwinding machine, thereby improving the production efficiency of the unwinding machine; the rolling connection between the support roller 504 and the coil can reduce the resistance encountered by the coil during unwinding, thereby reducing the energy consumption of the equipment; the setting of the elastic connecting member can make each support roller 504 fit closely with the surface of the coil, thereby improving the support effect on the coil; and during the loading process, the elastic connecting member can also absorb part of the impact force generated by the coil on the bottom plate 501, thereby reducing the loss rate of the equipment and extending the service life of the equipment.

[0029] Further improvements are, Figure 1 As shown, the machine body 1 is provided with a track 3 distributed along the axial direction of the unwinding shaft 2, and a movable carriage 4 is arranged on the track 3. The movable carriage 4 has moving wheels that roll along the track 3. The movable carriage 4 is internally provided with a motor that drives the moving wheels to rotate. The moving wheels drive the movable carriage 4 to move along the track 3 as a whole, thereby realizing the conveyance of the coiled material; the track 3 arranged along the axial direction of the unwinding shaft 2 can move the coiled material along the axial direction of the unwinding shaft 2, facilitating the insertion of the unwinding shaft 2 into the coiled material for docking.

[0030] Further improvements are, Figure 2 As shown, the mobile trolley 4 is vertically fixedly connected to a plurality of guide sleeves 402. The guide sleeves 402 are coaxially slidably fitted with guide posts 505 fixedly connected to the base plate 501. The mobile trolley 4 is also provided with a thrust member 401 for driving the base plate 501 to rise and fall. The guide posts 505 and guide sleeves 402 are provided to guide and limit the rise and fall of the base plate 501, thereby improving the stability of the base plate 501. The thrust member 401 is a hydraulic cylinder, which provides power to achieve the rise and fall of the base plate 501, thereby improving the convenience of docking the coiled material with the unwinding shaft 2.

[0031] Further improvements are, Figure 4 and 5As shown, the elastic connector includes a guide hole 508 vertically defined in the base plate 501, a guide rod 512 coaxially slidingly engaged with the guide hole 508, and a spring 511 sleeved around the outer periphery of the guide rod 512. The end of the support roller 504 is fixedly connected to the inner ring of a bearing 513, the outer ring of the bearing 513 is fixedly connected to the guide rod 512, and the ends of the spring 511 are respectively connected to the base plate 501 and the outer ring of the bearing 513. The guide hole 508 and the guide rod 512 cooperate to guide and limit the support roller 504, enhancing the stability of the support roller 504 during its lifting and lowering. The bearing 513 is provided to enhance the smoothness of the rotation of the support roller 504. When the spring 511 is in a compressed state, the elastic force generated by it exerts an upward thrust on the support roller 504, thereby allowing the support roller 504 to closely contact the bottom surface of the web and improving the support effect of the support roller 504 on the web.

[0032] Further improvements are, Figure 2 and 3 As shown, two side baffles 502 are provided on the top surface of the bottom plate 501. The side baffles 502 are arranged perpendicular to the axial direction of the unwinding shaft 2, and each support roller 504 is arranged between the two side baffles 502. The provision of the side baffles 502 can improve the stability of the support rollers 504 and limit the axial movement of the coil along the support rollers 504 during the unwinding process, thereby improving the unwinding accuracy of the unwinder.

[0033] Further improvements are, Figure 3-5 As shown, the side baffle 502 is vertically provided with a plurality of slots 506. The outer ring of the bearing 513 is fixedly connected to a sliding seat 509, which slides in engagement with the slots 506. The slots 506 and sliding seat 509 cooperate with each other to limit and guide the raising and lowering of the bearing 513, thereby improving the stability of the support roller 504 during the raising and lowering process. The top of the slots 506 is connected to the outside, which facilitates the assembly and disassembly of the sliding seat 509 within the slots 506, thereby improving the convenience of assembling and disassembling the support roller 504.

[0034] Further improvements are, Figure 4 and 5 As shown, both side walls of the slot 506 are vertically provided with positioning grooves 507, and the sliding seat 509 is fixedly connected to a positioning block 510 that slidably engages with the positioning grooves 507. The arrangement of the positioning block 510 and the positioning grooves 507 can be used to confine the sliding seat 509 within the slot 506, preventing the sliding seat 509 from escaping, and further improving the stability of the support roller 504.

[0035] Further improvements are, Figure 2 and 3As shown, two positioning rollers 503 are further disposed between the two side guards 502. The ends of the positioning rollers 503 are connected to the side guards 502 via bearings 513. The positioning rollers 503 and the support rollers 504 are parallel to each other, and each support roller 504 is disposed between the two positioning rollers 503. The two positioning rollers 503 and each support roller 504 are evenly spaced along an axial direction perpendicular to the unwinding shaft 2, and the two positioning rollers 503 are located at both ends. The positioning rollers 503 are connected to the side guards 502 via bearings, so the positioning rollers 503 can only rotate in place. The positioning rollers 503 can confine the coil between the two positioning rollers 503, preventing the coil from rolling off the bottom plate 501.

[0036] A further improvement is that the opposing sides of the two side guards 502 are provided with a lubricating layer. The lubricating layer can be a polytetrafluoroethylene layer. The provision of the lubricating layer can reduce the friction between the side guards 502 and the coil, reducing the mutual wear between the two. The movable carriage drives the coil along the axial direction of the unwinding shaft 2, which can also be used to adjust the position of the coil, facilitating the connection between the unwinding coil and subsequent processing equipment, thereby improving the unwinding efficiency of the equipment.
