Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to a film rolling device for a tobacco seedling greenhouse. Background Art

[0002] With the continuous progress of society, the traditional agricultural production model can no longer meet the needs of the development of modern civilization. New types of facility agriculture are sought after by people in the industry. Greenhouses are one of them. Greenhouses can transmit light, keep heat (or heat), and are facilities for cultivating plants. In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase yields. Tobacco seedlings can also be planted inside the greenhouse. When using a greenhouse, a tobacco seedling greenhouse film rolling device is required. The tobacco seedling greenhouse film rolling device is an automated equipment for greenhouses, designed to improve the ventilation and cooling capacity of the greenhouse, protect the safety of the greenhouse, and promote the growth and development of tobacco seedlings.

[0003] Chinese patent publication number CN216931098U discloses a film rolling device for a tobacco seedling greenhouse, comprising a first support rod, a second support rod disposed on one side of the first support rod, and a base fixedly connected to the bottom ends of the first and second support rods. The tobacco seedling greenhouse film rolling device is provided with a servo motor, a drive shaft, a connecting shaft, and a mounting sleeve. When the greenhouse film needs to be rolled up, the servo motor is started, and the servo motor drives the connecting shaft to rotate via the drive shaft, causing the base to roll the greenhouse film. Winding the greenhouse film facilitates ventilation of the interior of the greenhouse body. When the connecting shaft needs to be disassembled, the mounting sleeve is unscrewed from the outside of the connection between the connecting shaft and the drive shaft. After unscrewing the mounting sleeve, the connecting shaft is taken out of the interior of the mounting slot to complete disassembly. Disassembling the connecting shaft facilitates transportation of the device, thereby resolving the problem of inconvenient disassembly and use of the device.

[0004] However, the above technical solution has the following shortcomings: the limiting roller squeezes the greenhouse film under the action of the limiting spring. As the greenhouse film is continuously rolled up, the greenhouse film wound on the surface of the connecting shaft becomes thicker and thicker, and the limiting roller squeezes the greenhouse film more and more, which not only causes the workload of the servo motor to increase, but also easily damages the greenhouse film, affecting the subsequent use of the greenhouse film.
