It is only for the convenience of describing the present invention patent and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention patent. In addition, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention patent can be understood according to specific circumstances.

[0024] See Figure 1-2 As shown, a detachable coiling reel includes a first reel 1, on which a first reel shaft 2 is provided. The axial centerlines of the first reel 1 and the first reel shaft 2 coincide, and a first through hole 3 is axially opened between them. A second reel shaft 4 is arranged in the first through hole 3, and the second reel shaft 4 is threadedly connected with the first through hole 3. A second reel 5 is provided on the second reel shaft 4. The axial centerlines of the second reel shaft 4 and the second reel 5 coincide, and a second through hole 6 is axially opened between them. Wherein, in this embodiment, when the second reel 5 is connected to the first reel shaft 2 through the second reel shaft 4, the first reel 1 and the second reel 5 are oppositely arranged, and one end of the first reel shaft 2 away from the first reel 1 abuts against the second reel 5. When disassembling, by pulling the first reel 1 and the second reel 5, the second reel shaft 4 is screwed out of the first through hole 3, that is, the disassembly between the first reel 1 and the second reel 5 is realized. When installing, the second reel shaft 4 is screwed into the first through hole 3, that is, the connection between the first reel 1 and the second reel 5 is realized. Thus, the quick disassembly and assembly of the coiling reel are realized, and then the reuse is realized. When in use, by driving the coiling reel to rotate, the strip is wound around the first reel shaft 2 between the first reel 1 and the second reel 5.

[0025] Wherein, in this embodiment, the materials of the first reel 1, the first reel shaft 2, the second reel shaft 4, and the second reel 5 are all made of plastic. During processing, the first reel 1 and the first reel shaft 2 are integrally formed by injection molding, and the second reel 5 and the second reel shaft 4 are also integrally formed by injection molding.

[0026] Further, in this embodiment, the aperture diameter of the second through hole 6 is the same as that of the first through hole 3. Of course, the above is only one implementation manner and is not used to limit the scope of the present application. In actual setting, as long as it is ensured that the aperture diameter of the second through hole 6 is not greater than that of the first through hole 3.

[0027] Further, in this embodiment, continue to refer to Figure 1-2 As shown, the first disk 1 and the second disk 5 have the same structural shape and both adopt disks; wherein, screw holes 7 and observation holes 8 are provided on both the first disk 1 and the second disk 5; wherein, in this embodiment, when the first disk 1 and the second disk 5 are injection molded, the screw holes 7 are formed by wrapping hexagon socket head cap nuts therein. When in use, refer to Figure 3 As shown (in the figure, reference numeral A represents the fixed shaft; reference numeral B represents the connecting disk; reference numeral C represents this coil reel), the coil reel is sleeved and clamped on the fixed shaft of a driving device through the first through hole 3 and the second through hole 6, and the coil reel is driven to rotate by the fixed shaft of the driving device. When driving the coil reel to rotate, in order to prevent loosening or displacement of the fixed shaft on the coil reel, which affects the coiling of the coil reel, the first disk 1 and / or the second disk 5 are connected to the fixed shaft through a connecting disk. Specifically, the connecting disk is fixedly connected to the fixed shaft, and the connecting disk is fixedly connected to the first disk 1 and / or the second disk 5 through locking bolts. That is, after the locking bolts pass through the connecting disk, their front ends are screwed into the screw holes 7 and tightened. Among them, when fixing, all the screw holes 7 on the first disk 1 and / or the second disk 5 can be screwed into the locking bolts, or some of them can be screwed into the locking bolts; and the observation holes 8 penetrate through the inner and outer end faces of the first disk 1 and the second disk 5. Through the observation holes 8, it is convenient to observe the thickness of the strip wound on the first shaft 2. At the same time, by setting the observation holes 8, the use of materials can be reduced, the cost can be reduced, and the weight can be reduced.

[0028] Further, continue to refer to Figure 1-2 As shown, a limit threaded hole 10 for a countersunk head screw 9 to be locked into is provided on the first shaft 2; a limit groove 11 is provided at the front end of the threaded part of the second shaft 4; when the second shaft 4 is screwed into the first through hole 3, the limit groove 11 is aligned with the limit threaded hole 10. At this time, by screwing the countersunk head screw 9 into the limit threaded hole 10 and making the lower end of the countersunk head screw 9 extend into the limit groove 11, it can effectively prevent the second shaft 4 from rotating in the first through hole 3 during the process of winding the strip, thereby causing the coil reel to come loose.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
