[0015] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following describes in detail the specific embodiments, structures, features and their effects of the present utility model in combination with the attached drawings and preferred embodiments.

[0016] As Figures 1 to 3As shown in the figure, a positioning device for the spare shaft of a rewinder includes a frame 1, a winding device, a cutting device, and a spare shaft placement device. The winding device, the cutting device, and the spare shaft placement device are all installed on the frame 1. The winding device includes a guide roller 2, a main roller 3, and a winding roller 4. The main roller 3 is arranged on one side of the guide roller 2 and below the spare shaft placement device. The winding roller 4 is arranged on one side of the cutting device. Both ends of the winding roller 4 are connected to the winding roller positioning seat 5. The cutting device includes a cutting blade 6, a first cylinder 7, a cutting support frame 8, and a cutting support rod 9. The cutting blade 6 is fixed on the first cylinder 7. The first cylinder 7 is sleeved on the cutting support rod 9. The cutting support rod 9 is installed on the cutting support frame 8. The cutting support frame 8 is fixed on the inner side surface of the frame 1. The spare shaft placement device includes a positioning plate, a shaft hook 10, a second cylinder 11, and a third cylinder 12. There are two groups of the positioning plate, the shaft hook 10, the second cylinder 11, and the third cylinder 12. The positioning plate is installed on the top of the bracket 1. The shaft hook 10 is fixed on the top of the second cylinder 11. One end of the third cylinder 12 is connected to the second cylinder 11 through a hinge 13. The base of the second cylinder 11 is sleeved on a bearing (not marked in the figure). The bearing (not marked in the figure) here is independently separated from the bearing (not marked in the figure) of the main roller 3, and the two do not affect each other.

[0017] In this embodiment, the guide rollers 2 are multiple guide rollers 2 arranged in an interleaved manner. Both ends of each guide roller 2 are connected to the inner side surface of the frame 1.

[0018] In this embodiment, the winding roller positioning seat 5 is arranged on the upper part of the frame 1. A fourth cylinder 14 connected to both ends of the winding roller 4 is arranged inside the winding roller positioning seat 5, which is used for clamping and loosening the winding roller 4 to realize the fixing and disassembly of the winding roller 4. The bottom of the winding roller positioning seat 5 can slide along the slideway 15 on the top of the frame 1.

[0019] In this embodiment, a frame support rod 16 is also installed on the lower part of the inner side of the frame 1.

[0020] In this embodiment, there are two positioning plates, including a left positioning plate 17 and a right positioning plate 18, which are symmetrically installed on the bracket 1.

[0021] Specific usage process: During actual use, after placing the spare shaft 20 on the top of the support plate 19, both ends of the spare shaft 20 abut against the inner sides of the left positioning plate 17 and the right positioning plate 18. The left positioning plate 17 and the right positioning plate 18 precisely position the axial direction of the spare shaft 20. After the spare shaft 20 reaches the appropriate position, start the second cylinder 11. The second cylinder 11 moves downward, and the shaft hook 10 fixed to the top of the second cylinder 11 also moves downward. The shaft hook 10 presses tightly on the upper surface of the spare shaft 20, achieving the fixation of the spare shaft 20 by the shaft hook 10. When the number of meters of the material wound on the winding roller 4 reaches the set value, start the first cylinder 7. Control the first cylinder 7 to move along the cutting support rod 9 through the solenoid valve. The cutting blade 6 fixed to the first cylinder 7 cuts the material. After cutting, the first cylinder 7 returns to its original position. The fourth cylinder 14 in the winding roller positioning seat 5 moves backward, realizing the release of the winding roller 4 and the fourth cylinder 14. The wound material is transported to the designated location to perform the roll change operation. The bottom of the winding roller positioning seat 5 slides along the slideway 15 on the top of the frame 1 and approaches the spare shaft placement device. Start the third cylinder 12. The third cylinder 12 causes the second cylinder 11 to flip along the bearing (not marked in the figure), so that the shaft hook 10 flips downward to be parallel to the horizontal plane. Quickly move the spare shaft 20 and install it in the winding roller positioning seat 5. The fourth cylinder 14 in the winding roller positioning seat 5 moves forward, realizing the fixation of the winding roller 4 and the fourth cylinder 14. The winding motor 21 operates, and the material is re-metered and wound. In the present utility model, after the left positioning plate 17 and the right positioning plate 18 precisely position the axial directions of both ends of the spare shaft 20, then the second cylinder 11 moves downward, and the shaft hook 10 presses tightly on the top of the spare shaft 20 to achieve the fixation of its position. The left positioning plate 17 and the right positioning plate 18 automatically correct the deviation of the spare shaft 20, solving the problem of positioning failure when installing the upper spare shaft 20 in the prior art, improving the overall working efficiency of the equipment, reducing the workload of the staff, and having high practical value.

[0022] In summary, the present utility model achieves the expected effect.

[0023] The above is only a preferred embodiment of the present utility model, and it does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to make equivalent embodiments with equivalent changes, but as long as it does not depart from the technical content of the present utility model, any brief modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
