Description

Technical Field

[0001] The utility model relates to the technical field of adjustable film placing, in particular to an adjustable film placing frame for a laminating machine. Background Art

[0002] During the early spring sowing period, the temperature is low and the soil temperature rises slowly, which is not conducive to seed germination and seedling growth. At this time, using an agricultural laminating machine to cover the film can effectively increase the ground temperature, create temperature conditions suitable for seed germination and seedling growth, promote early emergence of crops, and lay a good foundation for a good harvest. In arid and rainy areas, soil moisture evaporates quickly, and crop growth faces the dilemma of water shortage. Using an agricultural laminating machine for laminating operations can reduce soil moisture evaporation, maintain soil moisture, and provide crops with a relatively stable moisture environment, which helps to improve crop yield and quality. At the same time, in winter, low temperatures and cold winds may cause frost damage to crops, and laminating machines are also needed.

[0003] Use a laminating machine to cover the surface of the land with plastic film through a mechanical device. First, before using the agricultural laminating machine, carefully check whether all parts of the equipment are intact. Then, according to the needs of crops and soil conditions, select the film, and then install the film reel on the bracket of the laminating machine, and pull out one end of the film, pass it through the guide device, start the power equipment, and drive the laminating machine forward slowly. After the operation is completed, clean the dirt and debris on the laminating machine in time to keep the equipment clean.

[0004] Laminating machine is a kind of equipment widely used in agricultural production. It can effectively prevent the evaporation of soil moisture and retain the moisture in the soil for a long time, which provides a stable and sufficient water supply for the growth of crops, reduces the frequency of irrigation and water consumption, and reduces agricultural production costs. During the laminating process, excessive tension will cause the film to bear too high a tensile force. When it exceeds its bearing limit, it will break, resulting in interruption of the laminating operation and reduced work efficiency. Insufficient tension will make the film loose and may accumulate dust, debris or moisture during subsequent use, providing conditions for the breeding of pests and diseases, and increasing the risk of crop diseases and pests.
