[0027] Example 1, by Figures 1-6 As shown, this utility model includes a bracket 1, with a mobile cart assembly 2 at the lower end of the bracket 1. The bracket 1 is mounted on the upper end of the mobile cart assembly 2. The upper end of the bracket 1 is rotatably connected to a rotating shaft 4 via a bearing seat 3. One end of the rotating shaft 4 is connected to a driven gear 5. The lower end of the driven gear 5 is meshed with a driving gear 6. One end of the driving gear 6 is equipped with a motor 7. The driving gear 6 is mounted on the output end of the motor 7. The motor 7 is located on the upper end of the mobile cart assembly 2.

[0028] A baffle 8 is fixedly sleeved on one side of the outer side of the rotating shaft 4. A rotating sleeve 9 is threadedly sleeved near the edge of the outer end of the rotating shaft 4. A lever 10 is connected to the outside of the rotating sleeve 9. A sleeve 11 is provided on one side of the rotating sleeve 9. The sleeve 11 is movably sleeved on the outside of the rotating shaft 4, and the sleeve 11 is rotatably connected to the side end of the rotating sleeve 9.

[0029] The outer wall of the sleeve 11 has three lower U-shaped seats 12 distributed around its circumference. The inner sides of each lower U-shaped seat 12 are rotatably connected to a connecting rod 13. The upper end of the connecting rod 13 is rotatably connected to an upper U-shaped seat 14. The outer end of the upper U-shaped seat 14 is connected to a support plate 15. The side of the support plate 15 near the baffle 8 is connected to a positioning block 16. One end of the positioning block 16 is connected to a limit pin 17. The surface of the baffle 8 is provided with a limit groove 18 corresponding to the limit pin 17. The limit pin 17 is located in the limit groove 18. Through the cooperation of the limit pin 17 and the limit groove 18, the expansion and contraction of the support plate 15 can remain stable.

[0030] The mobile vehicle assembly 2 includes a base frame 201. Four casters 202 are installed at the lower corners of the base frame 201. A push rod 203 is connected to one side of the base frame 201. First connecting rods 204 are rotatably connected to both sides of the upper end of the base frame 201. A second connecting rod 205 is rotatably connected to the middle of the first connecting rod 204. A support plate 206 is rotatably connected to the upper end of the second connecting rod 205. The support plate 206 is located above the base frame 201.

[0031] One end of the first connecting rod 204 is rotatably connected to an upper roller 207, and both sides of the lower end of the support plate 206 are connected to upper rails 208, with the upper roller 207 located inside the upper rails 208;

[0032] One end of the second connecting rod 205 is rotatably connected to a lower roller 209, and both sides of the upper end of the base frame 201 are connected to lower rails 210, with the lower roller 209 located inside the lower rails 210.

[0033] A connecting seat 211 is connected to the middle of one side of the lower end of the pallet 206. A first connecting block 212 is rotatably connected inside the connecting seat 211. A lead screw 213 is threaded through the inside of the first connecting block 212. A second connecting block 214 is threaded onto one side of the outer end of the lead screw 213. The two ends of the second connecting block 214 are rotatably connected to the first connecting rod 204 through a horizontal shaft 215. The horizontal shaft 215 is coaxial with the shaft at the center end of the upper roller 207.

[0034] One end of the lead screw 213 extends through to one side of the support plate 206 and is connected to a crank 216. A locking sleeve 217 is threaded onto the outside of the lead screw 213. A rotating rod 218 is connected to the outside of the locking sleeve 217. By rotating the rotating rod 218, the locking sleeve 217 is rotated, so that the locking sleeve 217 locks the lead screw 213 and prevents it from loosening after adjusting the height.

[0035] The outer end of the support plate 15 is connected to an arc-shaped rubber pad 19, which can increase the friction with the inner wall of the winding cylinder and ensure that the winding cylinder can remain stable. The driven gear 5 and the driving gear 6 are provided with protective covers 20 on their outer sides, which can play a protective role.

[0036] Working principle:

[0037] First, the winding cylinder is fixed to the outside of the support plate 15, and the film is wound around the winding cylinder to ensure that the winding cylinder can be tightly and stably fitted to the outside of the support plate 15. At this time, one end of the film is led out from the winding cylinder for subsequent winding operations.

[0038] In the initial state, the support plate 15 is in the retracted position. At this time, the positioning block 16 and the limiting pin 17 are located in the limiting groove 18 of the baffle 8. A certain gap is maintained between the support plate 15 and the winding cylinder to provide sufficient space for the installation of the winding cylinder.

[0039] By moving the lever 10, the rotating sleeve 9 is rotated, causing it to move axially on the rotating shaft 4. Since the rotating sleeve 9 and the sleeve 11 are connected by a thread, the movement of the rotating sleeve 9 will cause the sleeve 11 to move along the rotating shaft 4 toward the baffle 8.

[0040] As the sleeve 11 moves, the connecting rod 13 on its outer wall pushes the support plate 15 outward through the upper U-shaped seat 14. The outer end of the support plate 15 is connected to an arc-shaped rubber pad 19. When the support plate 15 is extended outward, the arc-shaped rubber pad 19 is in close contact with the inner wall of the winding cylinder, thereby achieving internal tension of the winding cylinder and ensuring that the winding cylinder will not loosen or shift during the winding process.

[0041] After the support plate 15 completes the internal tensioning operation, the motor 7 is started. The output end of the motor 7 drives the driven gear 5 to rotate through the driving gear 6, thereby driving the rotating shaft 4 to rotate.

[0042] The rotation of the shaft 4 drives the support plate 15 and the winding cylinder sleeved on its outside to rotate together. The film on the winding cylinder is gradually wound and tightened during the rotation. Due to the internal tensioning effect of the support plate 15 on the winding cylinder, the film can remain flat and tight during the winding process, avoiding wrinkles, deviations and other phenomena, and ensuring the winding quality.

[0043] Once the film is completely wound onto the winding drum, the motor 7 stops running, the shaft 4 stops rotating, and the winding process ends.

[0044] The mobile vehicle assembly 2 can be moved within the greenhouse as needed. By pushing the push rod 203, the moving wheels 202 on the mobile vehicle assembly 2 can flexibly change the position of the device, so that the film can be rolled up at different positions, improving the applicability and flexibility of the device.

[0045] By reversing the lever 10, the rotating sleeve 9 moves outward, causing the sleeve 11 to retract. The support plate 15 retracts inward under the action of the connecting rod 13, and the support plate 15 returns to its initial state, which facilitates the subsequent disassembly of the winding cylinder and replacement of the film.
