Clamping and positioning devices for clamping and positioning the ends of the core are provided on both sides of the H-shaped frame. The clamping and positioning devices include two movable plates respectively sliding on both sides of the H-shaped frame, an adjustment component one for driving the two movable plates closer to or away from both sides of the H-shaped frame, a slide groove vertically opened on the movable plate and passing through both sides, a slider slidably set in the slide groove, an adjustment component two for adjusting and controlling the slider's sliding relative to the slide groove, and a bullseye bearing fixed on the side of the slider facing the H-shaped frame. This utility model has the following advantages and effects: it can not only clamp and position the ends of the core to ensure stable unwinding of the core, but also help workers accurately adjust the position of the core and the roll material.

[0004] However, this patent is only convenient for feeding and unwinding rolls with shafts, and it is less convenient for using rolls without shafts. It has certain limitations in practical use, and the feeding of this patent requires the assistance of a forklift, which is also inconvenient. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0022] Figure 1 The diagram schematically illustrates a composite machine unwinding device with a double-material loading function, comprising a base plate 1, a pair of support columns 12 fixedly mounted on the top of the base plate 1, the pair of support columns 12 being symmetrically arranged, the pair of support columns 12 having a hollow structure, each pair of support columns 12 having a lifting device 2, each pair of support columns 12 having a sliding groove 13 on its outer wall, each pair of support columns 12 having a slider 14 slidably mounted in the sliding groove 13, the slider 14 being slidably connected to the pair of support columns 12 via the lifting device 2, the end of the slider 14 away from the sliding groove 13 having an integrally formed mounting plate 15, the mounting plate 15 having an mounting groove 16 having a clamping device 3, the sharp part of the base plate 1 having a rounded corner 4, the rounded corner 4 effectively reducing the damage caused by bumps and collisions and preventing scratches to the user, each of the four corners of the base plate 1 having an integrally formed mounting block 5, each mounting block 5 having a mounting hole 51 in the center, the device can be fixedly installed by setting bolts or other fixing tools in the mounting hole 51.

[0023] like Figure 2 and Figure 3 The lifting device 2 shown includes a first motor 21, which is fixedly installed on the top of the base plate 1. A worm gear 22 is fixedly connected to the output end of the first motor 21. A worm wheel 23 is rotatably connected to one side of the worm gear 22. The worm wheel 23 is rotatably installed inside the support column 12. A threaded rod 24 is fixedly installed on the top of the worm wheel 23. A slider 14 is threadedly connected to the surface of the threaded rod 24.

[0024] In specific implementation, the rotation of the first motor 21 drives the worm gear 22 to rotate, which in turn drives the worm wheel 23 to rotate. The rotation of the worm wheel 23 drives the threaded rod 24 to rotate, which in turn drives the threaded slider 14 connected to its surface to move. The movement of the slider 14 drives the mounting plate 15 to move, which in turn drives the clamping device 3 to move. This allows the user to control the height of the clamping device 3 by rotating the first motor 21 in both directions, thus facilitating the clamping of the roll material located below the clamping device 3 and avoiding the need to use forklifts or other tools to lift the roll material for loading.

[0025] like Figure 2 and Figure 4 The clamping device 3 shown includes a second motor 31, with a support platform 36 fixedly mounted at the bottom of the second motor 31. One end of the support platform 36 is fixedly connected to the mounting plate 15. The output end of the second motor 31 passes through the mounting plate 15 and is fixedly connected to a bidirectional threaded rod 32. The bidirectional threaded rod 32 is rotatably mounted in the mounting groove 16. Both ends of the bidirectional threaded rod 32 are threadedly connected to moving blocks 33. The top outer wall of the moving blocks 33 is rotatably connected to clamping blocks 34 through bearings. A blind hole 35 is opened in the middle of the clamping block 34. A reinforcing rod 6 is fixedly mounted on the top of the support platform 36. The other end of the reinforcing rod 6 is fixedly connected to the mounting plate 15. The reinforcing rod 6 forms a triangle between the mounting plate 15 and the support platform 36, thereby improving the stability of the support platform 36. The clamping block 34 is frustum-shaped. The special shape of the frustum-shaped clamping block 34 can effectively clamp shaftless coils of different diameters.

[0026] In practice, simply place the roll material to be loaded under the clamping block 34. Then, start the lifting device 2, which will align the clamping block 34 with the center point of the roll material. Then, start the second motor 31. The rotation of the second motor 31 will drive the bidirectional threaded rod 32 to rotate. The rotation of the bidirectional threaded rod 32 will cause the moving blocks 33 connected at both ends to move closer together. The moving blocks 33 moving closer together will cause the clamping blocks 34 to move closer together, so that the clamping blocks 34 can be inserted into the center point of the shaftless roll material, thus completing the fixation. The clamping block 34 has a blind hole 35, which allows the shaft of the axial roll material to be inserted into the blind hole 35, thus completing the fixation of the axial roll material. Then, start the lifting device 2 again to move the roll material to a suitable height.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
