Two fixing springs 9 and a handle 10 are fixedly connected to one side of the movable plate 8. Several fixing holes 6 are fixedly connected to the side of the movable plate 8 away from the fixing springs 9. When using this plastic film storage rack, the fixed insertion rod 11 first supports and fixes the plastic film roller 5 through the roller storage structure 4. Then, the handle 10 is pulled to move the moving plate 8, causing the fixed insertion rod 11 to move and separate from the fixed insertion hole 6. At this time, the fixing spring 9 is in a compressed state. Then, the rotating plate 3 drives the roller storage structure 4 and the plastic film roller 5 to rotate 180°. At this time, the fixed insertion rod 11 corresponds to the fixed insertion hole 6. Then, the handle 10 is slowly released, and under the reaction force of the fixing spring 9, the fixed insertion rod 11 is inserted into the interior of the fixed insertion hole 6, thereby completing the fixing operation of the rotating plate 3. At this time, the plastic film roller 5 is located inside the sealed space formed by the two L-shaped baffles 1, the rotating plate 3, the fixed support plate 401, and the moving support plate 406, thereby protecting the plastic film roller 5.

[0025] As an optional technical solution of this utility model, the roller storage structure 4 includes a fixed support plate 401, a slide groove 402, a lead screw 403, a crank handle 404, a slider 405, a movable support plate 406, and a support column 407. A support plate 401 is fixedly connected to one side of the rotating plate 3. A slide groove 402 is provided on one side of the rotating plate 3. The inner wall of the slide groove 402 is rotatably connected to the lead screw 403 via a bearing. A crank handle 404 is fixedly connected to one end of the lead screw 403. A slider 405 is threaded onto the outer surface of the lead screw 403. A movable support plate 406 is fixedly connected to the top side of the slider 405. The movable support plate 406 corresponds to the fixed support plate 401 in position, and the size of the movable support plate 406 is adapted to the fixed support plate 401. The movable support plate 406 and the fixed support plate 407... Several support columns 407 are fixedly connected to one side of the support plate 401. The positions of the support columns 407 connected to the movable support plate 406 and the support columns 407 connected to the fixed support plate 401 correspond to each other. When storing the plastic film roller 5, firstly, the support columns 407 connected to the fixed support plate 401 are inserted into the interior of the plastic film roller 5, and the plastic film roller 5 is tightly fitted with the fixed support plate 401. Then, the screw 403 is rotated by the crank handle 404. At this time, the slider 405 will drive the movable support plate 406 to move, so that the support columns 407 connected to the movable support plate 406 are inserted into the interior of the plastic film roller 5, and the movable support plate 406 is tightly fitted with the plastic film roller 5, thereby completing the fixed support operation of the plastic film roller 5.

[0026] As an optional technical solution of this utility model, a movable wheel 12 is fixedly installed on the bottom side of the L-shaped baffle 1, and a push-pull handle 13 is fixedly connected to one side of the L-shaped baffle 1. The movable wheel 12 is a self-locking universal wheel, and the plastic film storage rack can be moved by pushing and pulling the handle 13 and the movable wheel 12.

[0027] As an optional technical solution of this utility model, the cross-sectional shape of the guide rod 7 is T-shaped, and a part of the guide rod 7 is located inside the fixed spring 9. The end of the fixed spring 9 away from the moving plate 8 is fixedly connected to the end of the guide rod 7, so that the fixed spring 9 can generate elastic deformation as the moving plate 8 moves, and the guide rod 7 can prevent the fixed spring 9 from bending during the elastic deformation process.

[0028] As an optional technical solution of this utility model, the number of fixed insertion rods 11 corresponds to the number of fixed insertion holes 6. The fixed insertion rods 11 pass through the L-shaped baffle 1 and are slidably connected to the L-shaped baffle 1. The size of the fixed insertion rods 11 and the fixed insertion holes 6 are adapted to each other, so that the fixed insertion rods 11 can move smoothly and be inserted into the interior of the fixed insertion holes 6.

[0029] As an optional technical solution of this utility model, the width of both the fixed support plate 401 and the movable support plate 406 is the same as the height of the L-shaped baffle 1. The length of the fixed support plate 401 is equal to the minimum distance between the two L-shaped baffles 1, and the length of the movable support plate 406 is equal to the minimum distance between the two L-shaped baffles 1. Both the fixed support plate 401 and the movable support plate 406 are slidably connected to the L-shaped baffle 1, so that the movable support plate 406 and the fixed support plate 401 can rotate smoothly, and the sealing between the movable support plate 406 and the fixed support plate 401 and the L-shaped baffle 1 is relatively good, thereby providing a more comprehensive covering operation for the plastic film roller 5.

[0032] 1) Insert the support column 407 connected to the fixed support plate 401 into the interior of the plastic film roller 5, and make the plastic film roller 5 fit tightly against the fixed support plate 401;

[0033] 2) Rotate the lead screw 403 by cranking the handle 404. At this time, the slider 405 will drive the movable support plate 406 to move, so that the support column 407 connected to the movable support plate 406 is inserted into the interior of the plastic film roller 5, and the movable support plate 406 is tightly attached to the plastic film roller 5, thereby completing the fixed support operation of the plastic film roller 5.

[0034] 3) Pull the handle 10 to move the moving plate 8 and the fixed rod 11 to separate the fixed rod 11 from the fixed hole 6. At this time, the fixed spring 9 is in a compressed state.

[0035] 4) The rotating plate 3 drives the roller storage structure 4 and the plastic film roller 5 to rotate 180°. At this time, the fixed insertion rod 11 corresponds to the fixed insertion hole 6.

[0036] 5) Slowly release the handle 10. Under the reaction force of the fixed spring 9, the fixed rod 11 is inserted into the fixed hole 6, thereby completing the fixing operation of the rotating plate 3. At this time, the plastic film roller 5 is located in the sealed space formed by the two L-shaped baffles 1, the rotating plate 3, the fixed support plate 401 and the movable support plate 406, thereby protecting the plastic film roller 5.

[0037] In summary, this plastic film storage rack, through the coordinated arrangement of the L-shaped baffle 1, supporting shaft 2, rotating plate 3, roller storage structure 4, plastic film roller 5, fixed insertion hole 6, guide rod 7, moving plate 8, fixed spring 9, handle 10, and fixed insertion rod 11, not only makes the operation of storing the plastic film roller 5 more convenient, but also ensures that after storing the plastic film roller 5, it is located inside the sealed space formed by the two L-shaped baffles 1, rotating plate 3, fixed support plate 401, and moving support plate 406, thereby preventing the plastic film roller from... 5. To prevent damage to the plastic film caused by external factors such as scratches, the integrity of the plastic film is ensured. Through the coordinated arrangement of the fixed support plate 401, slide 402, lead screw 403, crank 404, slider 405, movable support plate 406 and support column 407, the distance between the movable support plate 406 and the fixed support plate 401 can be adjusted, thereby enabling the plastic film storage rack to store plastic film rollers 5 of a larger length, expanding the applicability of the plastic film storage rack, and improving its practicality and structural flexibility.
