This utility model, through the coordinated use of a motor, bearings, clamping tube, clamping body, clamping block, groove, and winding roller, can achieve automated control of the film rolling process, better improving the work efficiency of operators and increasing the practicality of the device.

[0004] However, this application does not allow for adjustment of the winding length, and when the film winding device is opened, insect repellent devices, monitoring devices, etc. need to be installed as needed, which is not conducive to functional expansion. Utility Model Content

[0005] The purpose of this application is to provide a greenhouse film rolling device to solve the problems mentioned above, such as the inability to adjust the winding length and the need to install insect repellent devices, monitoring devices, etc. on the outside of the film rolling device when it is opened, which is not conducive to functional expansion.

[0006] The technical solution adopted in this application is as follows: A greenhouse film rolling device includes a film rolling shell, an active tooth rotatably connected to the inner surface of the film rolling shell, a rolling rod welded to the outer surface of the output end of the film rolling shell, a sleeve movably sleeved on the outer surface of the rolling rod, an adjusting main shell movably sleeved on the outer surface of the sleeve, a second active tooth provided on the inner surface of the adjusting main shell, an adjusting tooth meshing with the outer surface of the second active tooth, and the inner surface of the adjusting tooth sleeved on the outer surface of the sleeve.

[0007] By adopting the above technical solution, the second active tooth inside the main shell rotates to drive the adjusting tooth, and the corresponding sleeve in the threaded groove of the adjusting tooth moves left and right to adjust the length. The first motor rotates the active tooth, and the film roll shell and the active tooth squeeze each other. The active tooth meshes with the support rack. Under the mutual force, the film roll shell is lifted as a whole. On the other side, through the force, the rolling rod and the sleeve are rolled up to complete the film rolling operation. This facilitates the mutual adjustment between the film roll shell and the main shell, and facilitates the rolling of greenhouse films of different lengths.

[0008] In a preferred embodiment, the film housing is provided with a first motor on the outer surface of the active tooth, and the outer surface of the output end of the first motor is welded to the active tooth.

[0009] By adopting the above technical solution, the first motor drives the active gear and the winding rod to provide mechanical power for the winding of the equipment through rotation.

[0010] In a preferred embodiment, a support rack is movably connected to the inner surface of the film roll housing corresponding to the active tooth, and a brake motor is fixedly connected to the upper surface of the film roll housing corresponding to the active tooth.

[0011] By adopting the above technical solution, the support rack meshes with the active tooth, which facilitates the lifting and lowering of the film roll shell. When the first motor is not in operation, the active tooth is fixed by the extension of the brake motor to complete the braking.

[0012] In a preferred embodiment, a second motor is fixedly connected to the outer surface of the film roll housing next to the first motor, and a second roll rod is welded to the outer surface of the output end of the second motor.

[0013] By adopting the above technical solution, the second motor provides mechanical power for the rotation of the second winding rod, and by placing a baffle cloth at the second winding rod, it can be wound up on the outside, providing a baffle cloth for the area.

[0014] In a preferred embodiment, an extension block is welded to the outer surface of the adjusting main body shell, and the inner surface of the extension block is movably sleeved onto the second coil rod.

[0015] By adopting the above technical solution, the outer extension block is sleeved with the second roll rod and rotated rapidly by the second motor to provide a membrane placement area.

[0016] In a preferred embodiment, a support block is welded to the outer surface of the main body shell, and a support column is movably sleeved on the inner surface of the support block.

[0017] By adopting the above technical solution, the support column is fixed to the outside of the greenhouse, and the support block is supported by being sleeved on the end away from the outer shell of the roll film.

[0018] In a preferred embodiment, a winding machine is provided on the outer surface of the extension block, and a fixing pin is provided on the outer surface of the winding machine.

[0019] By adopting the above technical solution, the fixing nail can be easily fixed at a high place or a better stress point for binding, which is more convenient for fixing. The spiral deformation and reset metal inside the winding machine provides inward force when the fixing nail is not under force, ensuring stable support.

[0020] In a preferred embodiment, a fixing block is movably sleeved on the outer surface of the second reel, and screws are provided on the outer surface of the fixing block.

[0021] By adopting the above technical solution, the fixing block is adjusted left and right at the second roll rod and then tightened with screws, which facilitates the placement of area barrier cloths or mosquito repellents.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] The second active tooth inside the main body shell rotates to drive the adjusting tooth. The threaded groove inside the adjusting tooth moves the sleeve left and right to adjust the length. The first motor rotates the active tooth, and the film roll shell and the active tooth squeeze each other. The active tooth meshes with the support rack. Under the mutual force, the film roll shell is lifted as a whole. On the other side, through the force, the rolling rod and the sleeve are rolled up to complete the film rolling operation. This facilitates the mutual adjustment between the film roll shell and the main body shell, and makes it convenient to roll greenhouse films of different lengths.

[0024] The second motor provides mechanical power for the rotation of the second winding rod. By placing a baffle at the second winding rod, winding can be performed on the outside, providing a baffle area for placement. The fixing nails can be removed for easy fixing at a high place or a better stress point for binding, making it easier to fix. The spiral deformation reset metal inside the winding machine provides inward force when the fixing nails are not under force, ensuring stable support. Attached Figure Description
