Foldable coil and greenhouse heat preservation device

Abstract

The invention provides a foldable coil and greenhouse heat preservation device, which relates to the technical field of a greenhouse built-in heat preservation material. The foldable coil comprises afirst solid structure layer and a multi-bubble structure layer; the multi-bubble structure layer is arranged on the first solid structure layer, the bubble structure zone is formed at the position ofthe bubble structure layer on the first solid structure layer, and a bubble-free folding zone is formed between the adjacent two bubble structure layers, and a bubble-free connection zone is formed atthe two sides of the first solid structure layer; the two adjacent bubble structures can be folded together along the bubble-free folding zone, or flattened along the bubble-free folding zone, multiple groups of foldable coils can be connected through the bubble-free connection zone. The greenhouse insulation device includes the above-described foldable coil. The utility model solves the problemthat the traditional bubble coil is not easy to be folded, and the volume occupies a large space after folding, and the traditional bubble coil is easy to shade and affect the growth of crops when applied in greenhouse.

Description

technical field [0001] The invention relates to the technical field of greenhouse built-in thermal insulation materials, in particular to a foldable coiled material and a greenhouse thermal insulation device. Background technique [0002] Bubble rolls are widely used in the field of packaging technology and heat preservation technology. When in use, they function in the form of covering in sheets or in the form of rolling in whole sheets. It is not necessary for the bubble rolls to have the functions of folding, shrinking and stretching. However, the above-mentioned air bubble coil is not easy to fold, and when it is forced to fold, the opposite surfaces cannot naturally close together, and it takes up a lot of space after being folded, so that when it is hung for use in the greenhouse space, it will cause great damage to the ground. The shading area affects the normal growth of plants in the greenhouse. [0003] Based on the above problems, it is particularly important to ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a foldable coiled material and a greenhouse heat preservation device to solve the problem that the traditional air bubble coiled material is not easy to fold, and after folding, the volume takes up a large space, and when it is used in a greenhouse, the shading area is large and affects the growth of crops.
