[0002] In industries such as packaging, printing, and composite material production, it is often necessary to unwind rolled materials (such as plastic film, aluminum foil, paper, non-woven fabric, etc.) and transport them to subsequent processing stations. During the transfer process, a center unwinding machine is needed to support the rolled materials.

[0003] In existing central unwinding machines, the rolled material is placed onto the unwinding shaft by a hoisting mechanism or a moving jacking mechanism, and then the ends of the rolled material are positioned. After unwinding, the material is connected to other equipment for transmission and processing. However, the position of the rolled material needs to be corrected during unwinding because different materials use different pipe diameters. Without adjustment, it is difficult to achieve a stable effect, which affects the feeding speed of the equipment. This needs to be optimized and improved. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 4 As shown, this application provides a center unwinding machine, including: a support frame 1, a rotating seat 3 rotatably connected to the inner center of the support frame 1, and limit bonding plates 4 rotatably connected to both sides of the top of the support frame 1.

[0026] The support frame 1 is provided with a correction and adjustment assembly on both sides. The correction and adjustment assembly includes a telescopic cylinder 5. A telescopic rod 7 is provided on one side of the telescopic cylinder 5. A fixed cylinder 9 is provided on the outside of the telescopic rod 7. An inner pressure block 13 is provided on the outside of the fixed cylinder 9.

[0027] Specifically, such as Figure 2 As shown, telescopic cylinder 5 is fixedly installed at the middle of the top of both sides of the support frame 1. A rotating rod 6 is fixedly connected to one side of the rotating seat 3, and a fixed cylinder 9 is fixedly connected to one side of the rotating rod 6. One end of the rotating rod 6 and the fixed cylinder 9 are rotatably connected through the rotating seat 3. The rotating seat 3 is connected to the servo motor through a transmission belt to provide rotational power.

[0028] Specifically, such as Figure 3 As shown, a protective cover 8 is fixedly connected to one end of the telescopic rod 7. The telescopic rod 7 and the fixed cylinder 9 are slidably connected. The protective cover 8 is at the end of the fixed cylinder 9 and is used to protect the material pipe wall when in contact. The end of the telescopic rod 7 is wider and protrudes out of the outside of the fixed cylinder 9.

[0029] Specifically, such as Figure 3 As shown, the inner side of the outer wall of the fixed cylinder 9 is provided with an adjustment groove 10 that is slidably connected to the telescopic rod 7, and the inner side of the telescopic rod 7 is provided with a slider that is adapted to the adjustment groove 10, which facilitates the improvement of the stability when the telescopic rod 7 and the fixed cylinder 9 slide relative to each other.

[0030] Specifically, such as Figure 3As shown, a fixing tube 11 is fixedly connected to the outside of the fixing cylinder 9. The fixing tube 11 is arranged in a ring. An elastic connector 12 is connected to the inside of the fixing tube 11. The fixing tube 11 is arranged in six equal rings to provide sliding support for the inner pressure block 13 on the outside.

[0031] Specifically, such as Figure 4 As shown, an inner pressure block 13 is slidably connected to one side of the fixed tube 11. The inner pressure block 13 is fixedly connected to the elastic connector 12. The inner pressure block 13 slides inside the fixed tube 11 via an extended rod. The sliding end is connected through the elastic connector 12 to provide buffer protection for sliding adjustment.

[0032] Specifically, such as Figure 4 As shown, connecting rods 14 are rotatably connected to both sides of the inner pressure block 13. Rotating connectors 15 are rotatably connected to the outer ends of the two connecting rods 14. The rotating connectors 15 at both ends are connected to the outer side of the telescopic rod 7 and the inner side of the fixed cylinder 9, respectively, so that when the telescopic rod 7 and the fixed cylinder 9 slide relative to each other, the connecting rods 14 can be rotated.

[0033] The inner side of the support frame 1 is provided with a guide feeding assembly, which includes a guide protective pad 2, and a feeding rack 18 is provided on one side of the guide protective pad 2.

[0034] Specifically, such as Figure 1 As shown, telescopic cylinders 16 are rotatably connected to both ends of the inner side of the support frame 1, and guide rods 17 are rotatably connected to the bottom inner side of the support frame 1. The feeding frame 18 is rotatably connected to one side of the telescopic cylinders 16. The guide rods 17 and the feeding frame 18 are fixedly connected, and the telescopic cylinders 16 and the feeding frame 18 are rotatably connected, which facilitates the stable swing adjustment of the feeding frame 18 and assists in feeding the product.

[0035] In this embodiment: when positioning the rolled material, the telescopic cylinder 5 drives the telescopic rod 7 to adjust its position. After the material is placed in the appropriate position, the telescopic rod 7 is pulled back, allowing it to slide inside the fixed cylinder 9, which in turn pushes the inner pressure block 13 outward, making it tightly adhere to the inner wall of the material tube, achieving a stable effect. When transferring the rolled material, it is transferred by a material transport trolley. When transferred to the inner side of the support frame 1, it is protected by the guide protective pad 2. The inner side is equipped with a telescopic cylinder 16 to drive the feeding frame 18 to adjust its position and cooperate with the feeding.

[0036] The specific solution is as follows: When transferring the rolled material, it is transferred by a material transport trolley. When it is transferred to the inside of the support frame 1, it is protected by the guide protective pad 2. The inner side is equipped with a telescopic cylinder 16 to drive the loading frame 18 to swing and adjust its position, which is in conjunction with the loading of the rolled material. Then the rolled material is inside the fixed cylinders 9 at both ends. The telescopic rod 7 at one end is extended to make the connecting rod 14 horizontal. The internal elastic connecting member 12 is compressed. Then the rolled material passes through the fixed cylinder 9 at one end. The other end is extended and adjusted by the telescopic cylinder 5. At this time, the rolled material is placed on the outside of the fixed cylinders 9 at both ends. Then the telescopic rod 7 is pulled back to make the telescopic rod 7 slide and adjust inside the adjustment groove 10, so that the inner pressure block 13 expands outside the fixed tube 11. The connecting rod 14 is rotated and connected to the rotating connecting members 15 on both sides to provide support force, so that the inner pressure block 13 with the arc edge is tightly attached to the material tube wall, achieving the effect of extrusion and positioning, improving the stability of the material when unwinding, and ensuring the efficiency of the equipment.
