Processing technology of greenhouse insulation quilt

Abstract

The invention relates to a processing technology of a greenhouse insulation quilt, which comprises an inner tube felt forming procedure, a surface felt forming procedure, a synthetic felt forming procedure and a quilting shaping procedure. The inner tube felt forming procedure comprises selection of raw materials, loosening through opening, airflow feeding, loosening through combing, needle puncturing, synthesis and the like, so as to prepare an inner tube felt. The processing technology of the invention can realize standardized operation, has high processing efficiency, and provides a complete set of processing line for processing of the insulation quilt. The processing procedures have the advantages of high degree of automation and high working efficiency, and not only reduce the labor intensity of workers, but also realize the industrialized and large-scale processing of insulation quilts and reduce the production cost. In addition, the insulation quilt produced with the processing technology has certain tension and certain bulkiness, can not be loosened during repeated folding and can not easily roll up to form spheres. Moreover, the insulation quilt produced with the processing technology has the advantages of easy storage of thermal energy, good insulation effect and long service life.

Description

technical field [0001] The invention relates to a processing technology of a thermal insulation quilt, in particular to a processing technology of a greenhouse thermal insulation quilt. Background technique [0002] In the past two decades, the number of greenhouse planting and greenhouse poultry breeding in my country has developed rapidly. The national greenhouse area has reached 17.1 billion square meters. In winter, the scope of planting or breeding in greenhouses includes vegetables, melons, flowers, poultry and other agricultural products. In terms of animal husbandry, the current insulation of greenhouses mainly uses straw curtains or ordinary bedding. [0003] Straw curtains and ordinary quilts have the following major drawbacks: [0004] 1. The thermal insulation effect is poor; when the outdoor temperature reaches minus 17°C in winter, the temperature in the greenhouse is required to reach above 12°C. Meet the requirements above 12°C; when the outdoor temperature ...

AI Technical Summary

Problems solved by technology

[0004] 1. The thermal insulation effect is poor; when the outdoor temperature reaches minus 17°C in winter, the temperature in the greenhouse is required to reach above 12°C. Meet the requirements above 12°C; when the outdoor temperature reaches minus 20°C, the straw curtain can no longer meet the normal needs of greenhouse insulation for eyesight, and when the outdoor temperature reaches minus 26°C, the straw curtain can no longer be used

[0005] 2. The service life is short and the cost of use is high. The service life of the straw curtain is generally 2 years, and it needs to be replaced in the third year. Moreover, it is easy to roll off by mechanical coiling, and it takes a lot of manpower to adjust, which causes manpower. The waste of material resources, the cost of using straw curtains is 7.11 yuan per square meter per year. When the straw curtains are exposed to strong sunlight in plateau areas, they generally need to be replaced every year, and the cost is high.

[0006] 3. Heavy weight, difficult to save, easy to pollute the environment, the weight of the straw curtain is heavy, the construction of the greenhouse needs to increase the support of the bracket, otherwise it is easy to crush the roof, increase the cost of building the greenhouse and shorten the service life of the greenhouse, and the straw It is easy to rot when exposed to water, especially in summer, and it is difficult to save. During the use of straw curtains, the rice leaves gradually age and break, and fall on the shed film to cause pollution of the shed film, reduce light transmittance, affect crop growth, and pollute the environment.

However, this technical solution is only a three-layer structure. The fibers of the three layers are composed of fibers of various materials. It is more complicated to select fibers of various materials. It is greatly affected, and the performance of the three-layer structure is basically the same, and there is no obvious strengthening effect
