Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural facilities technology, and in particular to an automatic rolling and lifting device for agricultural greenhouse insulation layer or light-transmitting film. Background Technology
[0002] Agricultural greenhouses are typically equipped with heat-insulating and light-transmitting films, shading nets, or insulation cotton (cloth). These materials frequently need to be rolled up according to climate and plant growth conditions to allow ventilation and light transmission, and to regulate temperature, humidity, carbon dioxide concentration, and light intensity within the greenhouse. To facilitate operation and improve production efficiency, many greenhouses are now equipped with automatic winding mechanisms that gradually roll up the heat-insulating and light-transmitting film or shading insulation cotton.
[0003] Currently, the heat-insulating and light-transmitting film or shading and heat-insulating cotton in agricultural greenhouses is usually fixed at the top of the greenhouse. When rolling it up, it is gradually rolled up from the lower side of the greenhouse towards the top. When an automatic winding mechanism is used for winding, the diameter of the wound heat-insulating and light-transmitting film or shading and heat-insulating cotton will become larger and larger. In addition, the automatic winding mechanism, including the roll of heat-insulating and light-transmitting film or shading and heat-insulating cotton, needs to move continuously towards the top of the greenhouse during the winding process in order to complete the automatic winding.
[0004] Existing agricultural greenhouses typically have transitional corners between the sides and top of their facades. To ensure the automatic film-rolling device can smoothly achieve automatic winding, please refer to the appendix. Figure 1 As shown, to prevent the automatic winding mechanism 2 from jamming at transition corners, a guide bracket 6 needs to be installed on the greenhouse to support and guide the automatic winding mechanism 2 as it moves along the greenhouse facade towards the roof. The main shape of the guide bracket 6 needs to match the exterior facade of the agricultural greenhouse. Since agricultural greenhouses are typically several meters to tens of meters wide, the existing guide bracket 6 needs to be made very tall, resulting in high costs. Furthermore, the guide bracket 6 is inconvenient to install and move on the greenhouse, which is not conducive to production use and fails to meet user needs. Utility Model Content
[0005] To address the aforementioned issues, the present invention aims to provide an automatic winding and lifting device for agricultural greenhouse insulation layers or light-transmitting films. This device features a simple structure, eliminates the need for additional guide supports, and ensures that the automatic winding mechanism remains perpendicular to the greenhouse support frame during the winding process. This prevents the automatic winding mechanism from jamming at transition corners and ensures smooth automatic winding operation.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic winding and lifting device for agricultural greenhouse insulation or light-transmitting film includes an automatic winding mechanism mounted on the greenhouse support frame. The automatic winding mechanism includes a main winding motor, a first reducer, and a winding shaft. The automatic winding mechanism is mounted on a sliding guide plate. When the automatic winding mechanism winds up, the sliding guide plate moves up and down along the greenhouse support frame. The automatic winding mechanism is equipped with a winding angle adjustment mechanism, which includes an angle adjustment reel, an adjustment belt, and an adjustment motor. One end of the adjustment belt is fixed in the angle adjustment reel, and the other end is fixed to the top of the greenhouse. When the automatic winding mechanism winds up, the adjustment motor drives the angle adjustment reel to rotate, tightening or loosening the adjustment belt, causing the sliding guide plate to swing around its front end, ensuring that the automatic winding mechanism remains perpendicular to the greenhouse support frame.
[0007] Furthermore, the front end of the sliding guide plate is provided with an arc surface or a guide roller, and when the angle adjustment reel rotates to tighten or loosen the adjustment belt, the sliding guide plate swings around the arc surface or the guide roller.
[0008] Furthermore, the greenhouse support frame includes columns, transition corners, and a top beam, and the length of the adjusting belt matches the travel distance of the automatic winding mechanism on the columns, transition corners, and top beam.
[0009] Furthermore, the column, transition corner, and top beam are provided with guide grooves that match the sliding guide plate.
[0010] Furthermore, the adjustment belt is a synchronous belt.
[0011] Furthermore, the top of the greenhouse is provided with a fixing bracket to fix the other end of the adjustment belt.
[0012] Furthermore, a second reducer is provided between the adjusting motor and the angle adjusting reel, and the adjusting motor includes a servo motor.
[0013] Furthermore, the main winding motor includes a servo motor.
[0014] Furthermore, the automatic winding mechanism is provided with a mounting bracket to facilitate the installation of the winding angle adjustment mechanism.
[0015] Furthermore, the greenhouse support frame is provided with two or more sets of automatic winding mechanisms and winding angle adjustment mechanisms in a staggered manner.
[0016] This utility model has the following beneficial effects: 1. This utility model sets a winding angle adjustment mechanism in the automatic winding mechanism. The winding angle adjustment mechanism can keep the automatic winding mechanism relatively perpendicular to the greenhouse support frame during the winding process, so as to avoid the automatic winding mechanism getting stuck at the transition angle and ensure smooth operation of automatic winding. Moreover, its structure is simple and does not require additional guide brackets.
[0017] 2. The winding angle adjustment mechanism of this utility model is equipped with an angle adjustment reel, an adjustment belt and an adjustment motor. The total length of the adjustment belt is determined according to the walking distance of the automatic winding mechanism on the greenhouse support frame. The servo motor is used to precisely control the length of the tightening or loosening of the adjustment belt to ensure that the automatic winding mechanism can remain relatively perpendicular to the greenhouse support frame at different positions, which is beneficial for automatic winding and avoids jamming of the automatic winding mechanism during winding.
[0018] 3. The greenhouse support frame of this utility model is provided with multiple sets of automatic winding mechanisms and winding angle adjustment mechanisms, which are used to wind different light-transmitting films, light-blocking nets or heat-insulating cotton, so as to facilitate automatic winding in layers.

The automatic winding mechanism 2 includes a main winding motor 21, a first reducer 22, and a winding shaft 23. The main winding motor 21 includes a servo motor.

The automatic winding mechanism 2 includes a servo motor 33 and an angle adjustment reel 31. A second reducer 34 is provided between the servo motor 33 and the angle adjustment reel 31. The adjustment belt 32 is a synchronous belt or other similar belt. One end of the adjustment belt 32 is fixed in the angle adjustment reel 31, and the other end is fixed to the top of the greenhouse. A fixing bracket 4 is provided at the top of the greenhouse to fix the other end of the adjustment belt 32. When the automatic winding mechanism 2 winds up, the servo motor 33 drives the angle adjustment reel 31 to rotate, tightening or loosening the adjustment belt 32, and causing the sliding guide plate 24 to swing around its front end, so that the automatic winding mechanism 2 can remain perpendicular to the greenhouse support frame 1.
[0026] The front end of the sliding guide plate 24 is provided with an arc surface or a guide roller. When the angle adjustment reel 31 rotates and the adjustment belt 32 is tightened or loosened, the sliding guide plate 24 swings around the arc surface or the guide roller to ensure smooth swinging.

The length of the adjusting belt 32 matches the travel distance of the automatic winding mechanism 2 on the columns 11, transition corners 12, and top beam 13. The length of the adjusting belt 32 is known, as are the length, curvature, or angle of each segment in the columns 11, transition corners 12, and top beam 13. The adjusting motor 33 is controlled by a program setting to rotate, causing the sliding guide plate 24 to swing around its front end, ensuring that the automatic winding mechanism 2 remains perpendicular to the greenhouse support frame 1 as it moves along the columns 11, transition corners 12, and top beam 13. The columns 11, transition corners 12, and top beam 13 are provided with guide grooves that match the sliding guide plate 24.
[0028] The greenhouse support frame 1 is provided with two or more sets of automatic winding mechanisms 2 and winding angle adjustment mechanisms 3, with each set of automatic winding mechanism 2 and winding angle adjustment mechanism 3 corresponding to different light-transmitting film, light-blocking net or heat-insulating cotton, so as to facilitate automatic winding in layers.
