[0025] As Figs. 1-6As shown, a paper roll storage device comprises a middle tube 1, the two ends of the middle tube 1 are shaped with a flange 10, and an end ring 11 is mounted on the flange 10 by screws. An end tube 2 is arranged in the middle tube 1, and the end ring 11 is sleeved on the end tube 2. In some embodiments, an outer threaded ring 22 is arranged on the inner side of the middle tube 1, and the middle tube 1 is connected to the outer threaded ring 22 by threads. The length of the end tube 2 can be limited by the end ring 11, so that the middle tube 1 and the end tube 2 are not separated. In addition, the threaded connection can prevent water vapor from entering, thereby improving the protection effect of the paper roll.

[0026] An outer cover 4 is arranged on the outer side of the end tube 2, and an outer ring 40 is arranged on the outer periphery of the outer cover 4. The outer ring 40 is sleeved on the outer side of the end tube 2. The arrangement of the outer cover 4 and the outer ring 40 can prevent water vapor from entering the end tube 2, thereby improving the sealing effect. A plurality of rectangular protrusions 3 are arranged on the outer periphery of the end tube 2, and a moving plate 31 is sleeved on the rectangular protrusions 3. A rectangular hole 36 is formed in the moving plate 31, and the rectangular protrusions 3 are arranged in the rectangular hole 36. The inner side of the moving plate 31 is bent to form an end plate 33. The outer side of the rectangular protrusions 3 is provided with a limiting outer plate 30. A rotating plate 37 is arranged on the limiting outer plate 30 by a first screw 35. The inner side of the rotating plate 37 acts on the end plate 33. The outer side of the moving plate 31 is bent to form a buckle plate 32. The inner wall of the buckle plate 32 abuts against the outer cover 4. A plurality of insertion plates 360 are arranged on the outer cover 4, and the insertion plates 360 are inserted into the buckle plate 32. The outer side of the end plate 33 is bent to form a limiting side plate 34, and the rotating plate 37 is located on the inner side of the limiting side plate 34. The buckle plate 32 facilitates the fixing operation of the outer cover 4. The inner wall of the outer cover 4 is tightly attached to the outer side of the end tube 2 by the pushing action of the rotating plate 37, thereby improving the sealing effect.

[0027] In operation, the operator adjusts the length of the end tube 2 according to the length of the paper roll. The length referred to herein is the length of the paper roll in the axial direction. During adjustment, the operator rotates the end tube 2 to move the outer side of the end tube 2 outward or inward. Then, the paper roll is placed in the cavity formed by the middle tube 1 and the end tube 2. Then, the two outer covers 4 are arranged on the end tube 2. After arrangement, the moving plate 31 is moved inward, so that the buckle plate 32 is located on the end face of the outer cover 4. Then, the operator rotates the rotating plate 37. When the rotating plate 37 rotates, the inner side of the rotating plate 37 acts on the end plate 33, so that the inner wall of the buckle plate 32 is tightly attached to the outer cover 4. At this time, the paper roll is closed and stored to prevent it from being damp and contaminated.

[0028] In some embodiments, the outer side end of the end pipe 2 is formed with a sealing ring 20, the inner periphery of the sealing ring 20 is in a tapered structure, and the outer side end of the tapered structure of the sealing ring 20 is a large end. The inner wall of the outer cover 4 is provided with an inner insert ring 7, the outer periphery of the inner insert ring 7 is in a tapered structure, and the outer periphery of the inner insert ring 7 is tightly attached to the tapered structure of the sealing ring 20. This design can further improve the sealing effect of the outer cover 4 on the end pipe 2 to prevent water vapor and the like from penetrating. The outer wall of the outer cover 4 is coaxially provided with an inner threaded pipe 42, the inner threaded pipe 42 is connected with a connecting pipe 43 through threads, the outer side end of the connecting pipe 43 is closed, and the inner side end thereof is open. The connecting pipe 43 is provided with a moving ring 47, the inner periphery of the moving ring 47 is formed with a tapered shell 49, the outer diameter of the moving ring 47 is greater than the diameter of the middle hole, and the tapered shell 49 extends into the inner part of the outer cover 4. The inner side end of the tapered shell 49 is a small end, the tapered shell 49 is provided with a spring 46, and the outer side end of the spring 46 acts on the inner side end of the connecting pipe 43. The inner side end of the connecting pipe 43 is provided with an end column 45, the inner side end of the tapered shell 49 is provided with a connecting column 50, one end of the spring 46 is sleeved on the end column 45, and the other end of the spring 46 is sleeved on the connecting column 50. The tapered shell 49 can be inserted into the both ends of the winding drum of the paper roll, thereby achieving the effect of fixing the paper roll to prevent damage to the paper roll due to rolling during transfer.

[0029] In the operation of the embodiment, when the outer cover 4 is covered, the outer periphery of the inner insert ring 7 is tightly attached to the tapered structure of the sealing ring 20, and the tapered shell 49 on the outer cover 4 also moves inward, and the tapered shell 49 is inserted into the both ends of the winding drum of the paper roll. In order to avoid the problem of damage to the winding drum due to the long movement distance of the tapered shell 49, the spring 46 is provided, which can prevent the paper roll from moving along the axial direction and also prevent the movement distance of the tapered shell 49 from being too large.
