[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4In this embodiment of the present invention, a drying device for fold-resistant yarn tube paper includes two end plates 1, an inner drying cylinder 9 is fixedly installed between the two end plates 1, and a first fixing stud 4 protruding outward is integrally formed at both ends of the inner drying cylinder 9. A through hole is opened inside the end plate 1 to mate with the first fixing stud 4, and a first locking nut 5 threadedly connected to the first fixing stud 4 is provided on the outer side of the end plate 1. A connecting flange 2 is integrally formed at the center of one end plate 1, and a rotating shaft 7 is welded at the center of the other end plate 1. A gear 8 is assembled on the outer wall of the rotating shaft 7. A replacement mechanism is provided on the outer periphery of the inner drying cylinder 9, and a limiting mechanism is provided on the two end plates 1 to limit the replacement mechanism.

[0020] In this embodiment: First, when the outer drying cylinder 6 installed outside the inner drying cylinder 9 develops surface rust or wear after prolonged use, the limiting mechanism on one end plate 1 is released. Then, the outer drying cylinder 6 is pulled outward until the rusted or worn outer drying cylinder 6 is completely removed. Afterward, a new outer drying cylinder 6 is re-attached to the outer periphery of the inner drying cylinder 9 through a replacement mechanism until one end of the outer drying cylinder 6 abuts against another part of the limiting mechanism. At this point, the outer drying cylinder 6 can no longer move. Then, the immobile outer drying cylinder 6 can be fixed by a part of the limiting mechanism. Using this method, the outer drying cylinder 6 can be easily replaced when surface rust or wear occurs, without the need for long-term downtime and extensive surface repair.

[0021] Please refer to this carefully. Figure 3 and Figure 4 The replacement mechanism includes multiple limiting grooves 10 formed on the outer periphery of the inner drying cylinder 9. The multiple limiting grooves 10 are equidistantly distributed in the circumferential direction. The replacement mechanism also includes limiting blocks 12 that are slidably connected to the inner wall of the limiting grooves 10. The outer wall of the limiting blocks 12 matches the inner wall of the limiting grooves 10. The outer periphery of the multiple limiting blocks 12 is integrally formed with an outer drying cylinder 6 that is sleeved on the outer periphery of the inner drying cylinder 9.

[0022] In this embodiment: when disassembling or installing the outer drying cylinder 6, the outer drying cylinder 6 is pulled outward, and the limiting block 12 on the inner circumference of the outer drying cylinder 6 moves along the limiting groove 10. After the replacement is completed, the rotating inner drying cylinder 9 can drive the outer drying cylinder 6 to rotate synchronously through the limiting block 12 and the limiting groove 10.

[0023] Please refer to this carefully. Figure 1 and Figure 2The limiting mechanism includes a limiting ring 3 welded to one edge of an end plate 1. The outer diameter of the limiting ring 3 is greater than or equal to the outer diameter of the inner drying cylinder 9. The limiting mechanism also includes multiple limiting plates 13 fixedly installed at one end of the outer drying cylinder 6. The multiple limiting plates 13 are evenly distributed in the circumferential direction. Multiple second-order fixing studs 11 are circumferentially distributed and welded to one end of the outer side of an end plate 1. The inside of the limiting plate 13 is provided with a circular hole that mates with the second-order fixing studs 11. The outer wall of the second-order fixing studs 11 is threaded with a second-order locking nut 14 that presses the limiting plate 13.

[0024] In this embodiment: when the outer drying cylinder 6 is installed by sliding on the outer periphery of the inner drying cylinder 9 through the replacement mechanism, until one end of the outer drying cylinder 6 contacts the limiting ring 3, the outer drying cylinder 6 can no longer move. At this time, the outer drying cylinder 6 drives the lower limiting plate 13 to be effectively inserted into the second fixing stud 11. At this time, the second locking nut 14 is threaded onto the outer periphery of the second fixing stud 11 until it is completely tightened. At this time, the tightened second locking nut 14 presses against the limiting plate 13, and the outer drying cylinder 6 can be limited to the current position, thus completing the connection of the outer drying cylinder 6.

[0025] It should be noted that the thickness of the outer drying cylinder 6 and the inner drying cylinder 9 are the same as the thickness of the drying cylinder in the prior art.

[0026] Please refer to this carefully. Figure 1 and Figure 2 The interior of the inner drying cylinder 9 is hollow, and a sealing ring is installed at the joint between the end plate 1 and the inner drying cylinder 9.

[0027] In this embodiment: the hollow structure of the inner drying cylinder 9 is used to supply high-temperature steam flow, and the design of the sealing ring can improve the sealing performance at the joint and prevent high-temperature steam leakage.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
