The outer support is composed of two outer supports 1, which is used to support the entire mechanism and provide a stable structural foundation. The inner support is composed of two inner supports 2, which is located between the two outer supports 1 and is used to support the winding roller 3.

[0029] With reference to Figure 3 The winding roller 3 is used to wind the light-proof high-barrier film, and both ends of the winding roller 3 are provided with roller shafts 7. The two roller shafts 7 are respectively located at the top of the two inner supports 2, so that the winding roller 3 can stably rotate.

[0030] In order to realize the connection of the roller shaft 7 and the outer support and allow it to rotate, the present application provides two rotating shafts 11. The two rotating shafts 11 are respectively rotatably arranged at the top end of the two outer supports 1.

[0031] Embodiment 2

[0032] With reference to Figures 3-4 On the basis of embodiment 1, the fixing assembly is provided in order to fix the rotating shaft 11 and the adjacent roller shaft 7. The fixing assembly is arranged on the outer wall of the rotating shaft 11, which is used to ensure the stable connection between the roller shaft 7 and the rotating shaft 11.

[0033] One end of the roller shaft 7 and the rotating shaft 11 is provided with a concave surface 20, and the two concave surfaces 20 are matched. When the roller shaft 7 is connected with the rotating shaft 11, the concave surfaces 20 can be embedded with each other to realize the preliminary connection.

[0034] The fixing assembly comprises a connecting ring 9, which is slidably sleeved on the outer wall of the rotating shaft 11. When the connecting ring 9 slides to the connection position of the two concave surfaces 20, it can be matched with the outer wall of the roller shaft 7, so as to fix the connection between the roller shaft 7 and the rotating shaft 11.

[0035] In order to further increase the stability of the connection, the outer wall of the roller shaft 7 is further fixedly sleeved with a limiting ring 8. The limiting ring 8 is located between the inner support 2 and the connecting ring 9, which is used to prevent the connecting ring 9 from sliding or falling off during the fixing process.

[0036] With reference to Figure 2In addition, the fixing assembly further comprises a limiting half ring 10 located between the outer support 1 and the connecting ring 9.

[0037] The outer support 1 is provided with a side groove 18 on one side close to the connecting vertical plate 4, and the connecting vertical plate 4 is fixedly provided with a fixing block 13 located inside the side groove 18.

Then the connecting vertical plate 4 is moved upward, and the two connecting vertical plates 4 are moved in the same way through the connecting horizontal plate 6, the connecting vertical plate 4 drives the limiting half ring 10 to move to the side of the connecting ring 9, so as to cooperate with the limiting ring 8 to prevent the displacement of the connecting ring 9. When the connecting vertical plate 4 is moved upward, the connecting vertical plate 4 will touch the inclined surface 19, so as to press the sliding plate 15 to move. When the fixing block 13 moves to the top of the inclined surface 19, the sliding plate 15 is reset through the compression spring 17, so as to fix the fixing block 13, and finally complete the installation of the winding roller 3. When it is necessary to replace, the fixing of the fixing block 13 can be released by pulling the sliding plate 15, the connecting vertical plate 4 will drive the limiting half ring 10 to move downward, and then the connecting ring 9 is moved to be separated from the connecting position of the two concave surfaces 20, so as to complete the disassembly. Then the new winding roller 3 is reinstalled on the top of the inner support 2 according to the above steps, so as to complete the replacement.
