When the positioning rod 17 passes over the wedge block 20, the wedge block 20 extends out of the first slide groove 18 under the action of the first spring 19, thereby fixing the positioning rod 17 in the second avoidance groove 16, so that the position of the installation shaft 14 is fixed.

[0026] To facilitate unfolding the cloth roll, the unfolding component 5 includes a plurality of positioning grooves 34 corresponding to each other on the two vertical rods 11, and a cloth pulling rod 35 is provided in the two corresponding positioning grooves 34 on the two vertical rods 11. One end of the cloth roll is bonded to the cloth pulling rod 35, and one side of the limiting disk 21 is fixedly connected to the fixing ring 23 by bolts. A rotating disk 28 is rotatably connected to the circumferential outer wall of the fixing ring 23, and a torsion spring 29 is welded to one side of the rotating disk 28. The other end of the torsion spring 29 is fixed to the circumferential outer wall of the fixing ring 23. A driving component for moving the cloth pulling rod 35 up and down is provided between the inner walls on both sides of the protective shell 1 and at the front side of the vertical rods 11. The driving component includes two rotating shafts 31 rotatably connected to the inner walls on both sides of the protective shell 1, and one side of the protective shell 1 is fixedly connected to the inner walls on both sides of the protective shell 1 by bolts. A driving motor 30 is fixedly connected to rotate one of the rotating shafts 31, two symmetrical pulleys 32 are fixedly connected to the circumferential outer walls of the two rotating shafts 31 by bolts, and the two pulleys 32 on the same side of the two rotating shafts 31 are connected by belt drive, two rubber blocks 33 are bonded to the two belts, and the distance between the two rubber blocks 33 is the same as the height of the cloth pulling rod 35, and a plurality of spaced electric push rods 36 are fixedly connected to the inner wall of one side of the protective shell 1 by bolts, one end of the electric push rod 36 is bonded to a magnetic block 37, and the other end of the magnetic block 37 is attracted to one side of the cloth pulling rod 35, when the cloth roll is installed, one end of the cloth roll is bonded to the cloth pulling rod 35, and when the cloth roll needs to be unfolded, the driving motor 30 is started first to rotate the two rotating shafts 31. The shaft 31 rotates synchronously through the pulley 32. When the two rubber blocks 33 on the belt are in front of the cloth-pulling rod 35 next to the cloth roll that needs to be displayed, the drive motor 30 is turned off, and the corresponding electric push rod 36 is started to extend, thereby pushing the cloth-pulling rod 35 into the two sets of rubber blocks 33. Then, the drive motor 30 is started again to make the two belts rotate synchronously and drive the cloth-pulling rod 35 to move up and down, so that the cloth roll can be unfolded. At this time, the cloth roll drives the rotating disk 28 to rotate and the torsion spring 29 is stressed. After the display is completed, the drive motor 30 is started to rotate in the opposite direction. At this time, the torsion spring 29 releases the torque to drive the rotating disk 28 to rotate in the opposite direction, thereby driving the cloth roll to be wound up and the cloth is recovered. When the cloth-pulling rod 35 reaches the initial positioning groove 34, the electric push rod 36 is started. 6 is extended so that the magnetic block 37 at one end thereof is adsorbed with the cloth-pulling rod 35, and then the electric push rod 36 is retracted so that the cloth-pulling rod 35 returns to the positioning groove 34.

Through the driving component provided, when the cloth roll needs to be unfolded, the driving motor 30 can be started to drive the cloth roll to be retracted and unwound. During this process, the staff does not need to touch the cloth roll, which further ensures the cleanliness of the surface of the cloth roll.

[0027] In order to ensure the dryness of the air inside the protective shell 1, the air circulation component 2 includes a plurality of square tubes 6 arranged on the inner wall at the bottom and on the inner walls on both sides of the protective shell 1. The two square tubes 6 located on the inner wall at the bottom of the protective shell 1 are each provided with an electric fan 1 7 for blowing air into the inside thereof, and the two square tubes 6 located on the inner walls on both sides of the protective shell 1 are each provided with an electric fan 2 8 for sucking air outwards. Both sides of the protective shell 1 are provided with a connecting pipe 9 for connecting the two square tubes 6 on the same side, and both connecting pipes 9 are provided with a detachable drying box 10. When it is necessary to dry the air inside the protective shell 1, a detachable drying box 10 can be provided on the two connecting pipes 9. When the electric fan 1 7 and the electric fan 2 8 are started, the electric fan 2 8 draws out the air inside the protective shell 1 and transports it to the connecting pipe 9, and the electric fan 1 7 transports the air in the connecting pipe 9 to the protective shell 1 to form a circulation. When the air passes through the connecting pipe 9, the moisture in the air is absorbed by the drying box 10 provided thereon, thereby ensuring the dryness of the air. The air in the protective shell 1 can be circulated by the air circulation component 2 provided. During the circulation process, the moisture in the air is absorbed by the drying box 10 to ensure the dryness of the air, thereby preventing the cloth roll from being damp and thus being damaged.

[0028] The present invention is divided into the following steps when used: S1: When the fabric roll needs to be installed, the wedge block 20 is first moved upward until it completely slides into the first slide groove 18, thereby exposing the positioning rod 17, and the installation shaft 14 is rotated out to the outside of the protective housing 1 with the rotating rod 13 as the center, and then the wedge block 20 is released. At this time, the first spring 19 releases the elastic force to push the wedge block 20 to slide downward along the first slide groove 18; S2: Then move the slider 25 on one of the limit plates 21 to make it move outward along the second slide groove 24 until its bottom end is out of contact with the fixed groove 22, and then slide it until it is out of the mounting shaft 14, and then install the fabric roll on the mounting shaft 14 and adjust the positions of the two limit components 4 according to the length of the fabric roll. When the installation is completed, reinstall the right limit component 4 on the mounting shaft 14 and limit the two ends of the fabric roll; S3: After the fabric roll is installed, one end of the fabric roll is bonded to the fabric pulling rod 35. When the fabric roll needs to be unfolded, the drive motor 30 is first started to make the two shafts 31 rotate synchronously through the pulley 32. When the two rubber blocks 33 on the belt are located in front of the fabric pulling rod 35 next to the fabric roll to be displayed, the drive motor 30 is turned off, and the corresponding electric push rod 36 is started to extend, and then the fabric pulling rod 35 is pushed into the two groups of rubber blocks 33. Then, the drive motor 30 is started again to make the two belts rotate synchronously to drive the fabric pulling rod 35 to move up and down, so that the fabric roll can be unfolded. At this time, the fabric roll drives the rotating disk 28 to rotate and the torsion spring 29 is stressed. S4: After the display is completed, the drive motor 30 is started to rotate in the reverse direction. At this time, the torsion spring 29 releases the torque to drive the rotating disk 28 to rotate in the reverse direction, thereby driving the cloth roll to be rolled up and the cloth is recovered. When the cloth pulling rod 35 reaches the initial positioning groove 34, the electric push rod 36 is started to extend so that the magnetic block 37 at one end is adsorbed with the cloth pulling rod 35, and then the electric push rod 36 is retracted, so that the cloth pulling rod 35 returns to the positioning groove 34; S5: When it is necessary to dry the air inside the protective shell 1, start the electric fan 1 7 and the electric fan 2 8 at the same time. The electric fan 2 8 draws the air inside the protective shell 1 and transports it to the connecting pipe 9. The electric fan 1 7 transports the air in the connecting pipe 9 to the protective shell 1 to form a circulation. When the air passes through the connecting pipe 9, the moisture in the air is absorbed by the drying box 10 provided thereon, thereby ensuring the dryness of the air.
