Description

Technical Field

[0001] This utility model relates to the field of rewinding machines, specifically a rewinding machine that can automatically load and unload cores. Background Technology

[0002] Rewinding machines are specialized equipment used to cut and rewind thick or wide rolls of material. The rewound material is usually mica tape, paper, or film.

[0003] In existing rewinding machines, workers need to place the core in the corresponding position on the winding roller, and then further wind the material to be rewound onto the surface of the core. After rewinding, workers still need to remove the core with the material attached to its surface from the winding roller. The step of coaxially fitting the core onto the winding roller is time-consuming and it is not easy to align the core and the winding roller coaxially. Therefore, the efficiency of rewinding the material is limited by the speed at which workers load and unload the core, resulting in low production efficiency for rewinding the material.

[0004] To address the aforementioned technical problems, this invention proposes a rewinding machine capable of automatically loading and unloading cores. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a rewinding machine with automatic loading and unloading of cores, comprising: a rewinding machine body 1, wherein a guide plate 2 and a support frame 3 are provided on the side of the rewinding machine body 1, an mounting plate 4 is provided on the side of the support frame 3, a drive motor 5 is provided in the mounting plate 4, a positioning plate 6 is installed in the support frame 3, a bearing 7 is provided in the positioning plate 6, a rotating rod 8 is provided in the bearing 7, and a positioning frame 9 is provided at one end of the rotating rod 8; a fixed frame 10, wherein an electric push rod 11 is provided on the side of the fixed frame 10, a moving plate 12 is provided at the lifting end of the electric push rod 11, and a first motor 13 is provided in the moving plate 12; a traction plate 14, wherein a support shaft 15 is provided in the traction plate 14, a vertical plate 16 is provided on the surface of the support shaft 15, a first arc plate 17 is provided at one end of the vertical plate 16, a second arc plate 19 is connected to the first arc plate 17 by a hinge 18, a limiting arc plate 27 is provided on the inner side of the support frame 3, and one end of the support shaft 15 is placed in the limiting arc plate 27;

[0027] When the core 101 needs to be installed, it can first be placed inside the first arc plate 17. Then, the second arc plate 19 is rotated through the hinge 18. The second arc plate 19 is then connected to the first arc plate 17 using the positioning bolt 26, thus fixing the core 101. The limiting arc plate 27 supports the other end of the support shaft 15, ensuring stable rotation of the support shaft 15 without bending. This also facilitates the subsequent insertion of one end of the core 101 into the positioning frame 9. Then, the first motor 13 can drive the support shaft 15 to rotate. When the angle is adjusted to a suitable angle, the support shaft 15 can be pushed by the electric push rod 11, and then one end of the core 101 can be inserted into the positioning frame 9 and fixed by the fixing bolt 20. Then, the core 101 can be rotated by the drive motor 5 to facilitate winding with the rewinder body 1. When it is necessary to disassemble the core 101, simply start the electric push rod 11 to disengage one end of the core 101 from the positioning frame 9, then use the first motor 13 to rotate the support shaft 15, and then rotate the second arc plate 19 to remove the core 101.

[0028] Example 2: Based on Example 1, in order to cooperate between the core 101 and the rewinder body 1, a first arc plate 17 and a second arc plate 19 are provided. The first arc plate 17 and the second arc plate 19 have the same structure. The side of the first arc plate 17 is provided with a placement groove 23. The side of the placement groove 23 is provided with a vertical rod 24. The surface of the vertical rod 24 is fitted with a needle roller bearing 25. The first arc plate 17 and the second arc plate 19 are fixed by positioning bolts 26. The vertical plate 16 is fixedly connected to the surface of the support shaft 15. There are two sets of vertical plates 16. Both sets of vertical plates 16 are provided with the surface of the support shaft 15. One end of the support shaft 15 is fixedly connected to the transmission end of the first motor 13.

[0029] When in use, after the core 101 is clamped by the first arc plate 17 and the second arc plate 19, the inner ring surface of the needle roller bearing 25 is fixedly connected to the surface of the upright 24. After inserting one end of the core 101 into the positioning frame 9, it is fixed by the fixing bolt 20, so that the drive motor 5 can be started to drive the core 101 to rotate, which facilitates the winding of the rewinding machine body 1. When the core 101 rotates, the friction between the core 101 and the first arc plate 17 and the second arc plate 19 can be reduced by the multiple sets of needle roller bearings 25 set in the first arc plate 17 and the second arc plate 19, which also facilitates the rotation of the core 101.

[0030] Example 3: Based on Example 2, a support shaft 15 is provided to facilitate the feeding of the core 101. The rotating rod 8 is fixedly connected to the inner ring surface of the bearing 7. The transmission end of the drive motor 5 is fixedly connected to the end face of the rotating rod 8. The core 101 is inserted into the positioning frame 9. The positioning frame 9 is screwed with a fixing bolt 20. The positioning plate 6 is fixedly connected to the support frame 3 with bolts. The guide plate 2 has a "T" shaped plate structure. The fixing frame 10 is fixedly connected to the side of the rewinder body 1. The moving plate 12 is fixedly connected to the lifting end of the electric push rod 11. The traction plate 14 has a positioning slot 21 on its side. The positioning slot 21 is sleeved on the guide plate 2. The traction plate 14 is provided with a limit bearing 22. The support shaft 15 is fixedly connected to the inner ring surface of the limit bearing 22.

[0031] In use, first loosen the fixing bolts 20 inside the positioning frame 9, then start the electric push rod 11 to move the moving plate 12 backward, thereby allowing the traction plate 14 to move on the guide plate 2, so that one end of the core 101 can be disengaged from the positioning frame 9. Then start the first motor 13 to drive the support shaft 15 to rotate. After the support shaft 15 is rotated to a suitable angle, the positioning bolts 26 can be removed, allowing the second arc plate 19 to rotate around the hinge 18, and then the core 101 can be easily removed from the first arc plate 17 without the need for staff to remove the core 101.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
