Air permeable plate and manufacturing method thereof

Abstract

The invention discloses an air permeable plate and a manufacturing method thereof. The air permeable plate comprises an upper plate, a medium plate and a lower plate which form a layered structure, wherein the upper plate and the lower plate are made of wear-resistant materials; the medium plate is made of a material with a high heat dissipation performance and a thermal deformation resistance; a plurality of first air permeable holes and first air permeable grooves are arranged at the upper plate; the first air permeable grooves are distributed at the periphery of the upper plate and face towards the middle position of the upper plate, and extend out of the upper plate; the medium plate is provided with second air permeable holes corresponding to the first air permeable holes; and the lower plate is provided with third air permeable holes corresponding to the second air permeable holes. The manufacturing method of the air permeable plate includes preparing materials, drilling and processing the air permeable grooves, and assembling. The air permeable plate of the invention has the advantages of wear resistance, long service life, small thermal deformation, stable operation, and simple manufacture.

Description

technical field [0001] The invention relates to the fields of vacuum skin packaging, elevator packaging and tight packaging, in particular to a breathable panel and a manufacturing method thereof. Background technique [0002] In production and life, it is often necessary to carry out vacuum skin packaging on objects. When vacuum skin packaging is carried out on articles, it is necessary to use a storage ventilating panel. The grooves mainly increase the ventilation flow, but the aluminum plate is easy to wear when cutting on the surface and rubbing on the back to produce aluminum dust, which pollutes the working environment. However, the use of pure stainless steel or iron plate is not only too heavy and difficult to operate, but also because it is easily deformed when heated. At the same time, in automatic packaging, the packaging film needs to be cut off after packaging. Since the cutting is performed at the same position every time, it is easy to scratch the storage vent...

Problems solved by technology

[0002] In production and life, it is often necessary to carry out vacuum skin packaging on objects. When vacuum skin packaging is carried out on articles, it is necessary to use a storage ventilation panel. The existing storage ventilation panels generally use a ventilation aluminum plate. The grooves mainly increase the ventilation flow, but the aluminum plate is easy to wear when cutting on the surface and rubbing on the back to produce aluminum dust, which pollutes the working environment. However, the use of pure stainless steel or iron plate is not only too heavy and difficult to operate, but also because it is easily deformed when heated. Use; at the same time, in automatic packaging, the packaging film needs to be cut off after packaging. Since the cutting is performed at the same position every time, it is easy to scratch the storage ventilation panel, reduce the strength of the storage ventilation panel, and shorten its service life.
