AI Technical Summary
[0003]然而,现有卷膜装置在收卷过程中因缺乏导向按压装置,导致薄膜张力不均、层间松散,易出现褶皱、偏移甚至卡滞,影响密封性与使用寿命
在卷膜过程中,导向轮紧贴薄膜表面,随着电机驱动卷轴将薄膜不断卷起,薄膜的厚度逐渐增加,卷径随之变大,此时,导向轮在弹簧的弹性作用下,能够向后滑动,实时补偿因卷径增大而产生的空间变化,从而始终保持与薄膜外层的紧密接触,以此不仅有效引导薄膜按预定轨迹收卷,防止偏移、褶皱或松脱,还能通过持续施加适度压力,提升收卷的整齐度和紧密性,弹簧提供的缓冲力避免了硬性挤压对薄膜造成的损伤,通过上述方案显著提高了卷膜过程的稳定性和可靠性,确保长期运行顺畅。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of film rolling device technology, and in particular to an automatic film rolling device for greenhouse windproof openings. Background Technology
[0002] The automatic film rolling device for greenhouse windbreaks is an intelligent device used in modern greenhouses. It is mainly used to control the opening and closing of windbreaks on the top or side of the greenhouse to regulate the temperature, humidity, carbon dioxide concentration and ventilation volume inside the greenhouse, thereby creating a suitable environment for crop growth.
[0003] However, existing film winding devices lack guiding and pressing devices during the winding process, resulting in uneven film tension, loose interlayers, wrinkles, misalignment, or even jamming, which affects sealing performance and service life.
[0004] To address these issues, we provide an automatic film rolling device for greenhouse windbreaks. Utility Model Content
[0005] This invention provides an automatic film rolling device for greenhouse windproof openings, which solves the problems mentioned in the background art.
[0006] This utility model provides an automatic film rolling device for greenhouse windproof openings, including a device body, a limiting component installed on one side of the device body, and the limiting component including a guide wheel disposed on one side of the device body.
[0007] Preferably, the surface of the main body of the device is threadedly connected to a mounting bracket, and a spring is welded to the surface of the mounting bracket.
[0008] Preferably, a connecting seat is welded to the other side of the spring, a rotating shaft is installed on the inner side of the connecting seat, and a guide wheel is rotatably connected to the inner side of the rotating shaft.
[0009] Preferably, a motor is installed on the outside of the main body of the device, an output rod is connected to the inside of the main body of the device via a key, and a power cord is provided inside the main body of the device.
[0010] Compared with the prior art, the beneficial effects of this utility model are: During the film winding process, the guide rollers are in close contact with the film surface. As the motor drives the reel to continuously wind up the film, the film thickness gradually increases, and the roll diameter increases accordingly. At this time, the guide rollers can slide backward under the elastic action of the springs, compensating for the spatial changes caused by the increase in roll diameter in real time, thus maintaining close contact with the outer layer of the film. This not only effectively guides the film to wind along a predetermined trajectory, preventing deviation, wrinkles, or loosening, but also improves the neatness and tightness of winding by continuously applying moderate pressure. The buffering force provided by the springs avoids damage to the film caused by hard compression. The above solution significantly improves the stability and reliability of the film winding process, ensuring smooth long-term operation. Attached Figure Description
[0011] To more clearly illustrate the technical solution of this utility model, the drawings used in the implementation examples will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.
[0012] Figure 1 This is a schematic diagram of the overall structure proposed in this utility model; Figure 2 This is a schematic diagram of the combined structure of the processing box, filter screen, and collection box proposed in this utility model.
[0013] In the diagram: 1. Main body of the device; 2. Limiting component; 201. Mounting bracket; 202. Spring; 203. Connecting seat; 204. Rotating shaft; 205. Guide wheel; 3. Motor; 4. Output rod; 5. Power cord. Detailed Implementation
[0014] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0015] See Figure 1-2 An automatic film rolling device for greenhouse windproof openings includes a device body 1. A limiting component 2 is installed on one side of the device body 1. The limiting component 2 includes a guide wheel 205 disposed on one side of the device body 1, which limits and fixes the film.
[0016] Furthermore, a mounting bracket 201 is threadedly connected to the surface of the main body 1 of the device, and a spring 202 is welded to the surface of the mounting bracket 201, through which the guide wheel 205 moves.
[0017] Furthermore, a connecting seat 203 is welded to the other side of the spring 202. A rotating shaft 204 is installed on the inner side of the connecting seat 203. A guide wheel 205 is rotatably connected to the inner side of the rotating shaft 204, and the rotating shaft 204 supports the rotation of the guide wheel 205.
[0018] Furthermore, a motor 3 is installed on the outside of the main body 1, and an output rod 4 is connected to the inside of the main body 1 via a key. A power cord 5 is installed inside the main body 1. The motor 3 controls the output rod 4 to rotate via the key, thereby realizing the film winding operation.
[0019] As can be seen from the above technical solution, the motor 3 controls the output rod 4 to rotate via a flat key, thereby realizing the film winding operation. During the film winding process, the guide wheel 205 is in close contact with the film surface. As the motor 3 drives the roller to continuously roll up the film, the thickness of the film gradually increases, and the roll diameter increases accordingly. At this time, the guide wheel 205 can slide backward under the elastic action of the spring 202, compensating for the spatial changes caused by the increase in roll diameter in real time, thus always maintaining close contact with the outer layer of the film. This not only effectively guides the film to be wound along a predetermined trajectory, preventing deviation, wrinkles, or loosening, but also improves the neatness and tightness of the winding by continuously applying appropriate pressure. The buffer force provided by the spring 202 avoids damage to the film caused by hard compression. The above solution significantly improves the stability and reliability of the film winding process, ensuring smooth long-term operation. This completes the use of an automatic film winding device for greenhouse windbreaks.

The above embodiments of this utility model do not constitute a limitation on the scope of protection of this utility model.
