Description

Technical Field

[0001] This utility model relates to the field of film covering device technology, and in particular to a film covering device for greenhouse construction. Background Technology

[0002] A solar greenhouse, also known as an energy-saving solar greenhouse or a warm shed, consists of two side walls, a rear wall, a supporting frame, and covering materials. It is a type of greenhouse unique to northern my country. It is a greenhouse that does not require internal heating; instead, it absorbs and releases solar energy through the rear wall to maintain a certain temperature level inside, meeting the needs of vegetable crops for growth. The south side is the sun-facing side and is also covered with a film. According to announcement number CN220586986U, a film covering device for a solar greenhouse is disclosed for unfolding the film to be stretched. It includes two sets of support structures, two slider groups, two hanging rails, and two second sliders. The support structures are respectively set on both sides of the greenhouse frame to be covered. Each support structure includes a guide rod. The slider groups are respectively slidably set on the two guide rods and include two first sliders. Each first slider is connected to a guide device. The two hanging rails are set between the two guide rods. The two ends of the hanging rails are respectively set on the corresponding first sliders. The second sliders are respectively set on the corresponding hanging rails. Each second slider is connected to a stretching device. The film to be stretched is correspondingly set on the two second sliders and the two first sliders on the same guide rod, so that the film to be stretched can be unfolded along the length direction of the hanging rails and the length direction of the guide rods. This invention enables automatic covering of greenhouses with film, reducing the difficulty of manual film covering and increasing the efficiency of greenhouse construction. However, the above technology still has some defects. For example, the traditional method of covering greenhouses with film usually involves manually laying the film. This method is not only time-consuming, but also makes it difficult to ensure the flatness and tightness of the film. The film is prone to damage during manual laying, which affects the service life of the greenhouse and needs to be improved. Utility Model Content

The combined design of the fixed plate 7, slider 10, sliding plate 12, fixing block 13, and threaded rod 15 makes the entire device more stable and reliable during operation, improving work efficiency. Simultaneously, the design of the clamping plate 17, rotating rod 18, and rotating wheel 19 allows for flexible adjustment of the film tension, ensuring the stability and service life of the greenhouse.

[0028] Working principle: In use, the film is first placed inside the rotating roller 5 and fixed to the middle of the side plate 2 via the mounting rod 4 and mounting groove 3. Then, the film passes through the groove 22 into the interior of the protruding plate 21 and is fixed. Next, the bottom plate 1 is pinched and pulled backward, causing the rotating wheel 19 to rotate via the rotating rod 18 in the middle of the clamping plate 17, thus moving the bottom plate 1. At this time, the film slides inside the protruding plate 21 via the groove 22. Since the protruding plate 21 is fixed to the surface of the side plate 2 via the connecting block 20, it can limit the film's movement. The rotating roller 5 rotates on the surface of the mounting rod 4 via the rotating groove 6. After laying, the protrusion 25 can be pinched and pulled to the right, causing the sliding block 24 to slide inside the protruding plate 21 via the sliding groove 23. At this time, the cutter 26 can... After the film is cut, when adjusting the rotating wheel 19 to meet different usage requirements, pinch the rotating block 16 and rotate it, so that the threaded rod 15 rotates backward inside the fixed block 13 through the fixed groove 14. At the same time, the threaded rod 15 rotates backward inside the slider 10 through the threaded groove 11. When the rotating block 16 is away from the surface of the fixed block 13, pinch the clamping plate 17 and push and pull it, so that the slider 10 slides inside the fixed plate 7 through the sliding groove 9. At the same time, the sliding plate 12 slides on the surface of the fixed plate 7, and the threaded rod 15 slides on the surface of the fixed plate 7 through the limiting groove 8. When the sliding plate 12 drives the rotating wheel 19 to slide to the required position through the clamping plate 17, pinch the rotating block 16 again and rotate it to fix it firmly.
