Quantitative cutting method for pulling cloth interlayer

Abstract

A quantitative cutting method for a pulling cloth interlayer is characterized in that the device comprises a horizontal spreading table, conveying rails, a cotton spreading machine, a laser probe, an automatic cutting device and cloth pressing clips. The cloth pressing clips are arranged at the two ends of the horizontal spreading table; the conveying rails are arranged on the two sides of the horizontal spreading table; the cotton spreading machine is erected on the rails so that the moving range of the cotton spreading cotton can reach the two ends of the horizontal spreading table. The layer number of core materials is determined according to a mating calculation method; then non-woven fabric is spread on a specific number of layers of glass fiber cotton cloth to achieve seamless connection type quick spreading of multiple batches of core materials; at last, positioning is conducted through lasers, cutting is conducted automatically, and the core materials are cut efficiently, quickly and accurately.

Description

technical field [0001] The invention belongs to the field of heat preservation, and in particular relates to a method for quantitatively and automatically cutting cloth interlayers of glass fiber core materials for vacuum insulation panels. Background technique [0002] As a high-efficiency thermal insulation material, vacuum insulation panels have been successfully used in home appliance insulation, cold chain logistics, building insulation and other fields. The effect of energy saving and emission reduction is obvious, and it has great development potential. During the promotion and use of vacuum insulation panels, fast and accurate cutting of core materials has become an unavoidable problem in increasing production and reducing labor costs. [0003] The original core material cutting mostly adopts the combination of mechanical spreading and manual size measurement and cutting. This method facilitates timely adjustment of the size and thickness of the core material and red...

Problems solved by technology

However, the device has a complex structure and a large volume. When the cloth is driven, the inner tension of the cloth is relatively large, which is easy to cause damage to the glass wool cloth, or even directly crack it.

[0005] The literature shows that the current research on fabric spreading and cutting focuses on fabric flatness, accurate length, neat sides, and tension-free spreading, but glass wool is less tough than ordinary fabrics. Neither outstanding
