Air exhaust device for starch packaging machine

Abstract

The invention relates to an air exhaust device for a starch packaging machine, belonging to the field of equipment for packaging starch. The air exhaust device comprises a filter element which is connected with a lifting mechanism; and an inner cavity of the filter element is connected with a vacuum extract device through a main pipeline which is provided with a valve. The filter element and the vacuum extract device of the pipeline connected with the filter element can ensure that air in bags can be exhausted; after the air is exhausted, the density of materials in packaging bags becomes greater, the packaging bags are firm, the bag stacking is convenient and the stacker scattering is not easy to generate; meanwhile, after the material density becomes greater, the packager volume becomes smaller and consumed packaging materials also become smaller, thereby greatly saving the cost; and after the materials become firm, in the process of loading, unloading and transporting, the package bags are not broken easily and does not leak dust, thereby ensuring that the net weight is more accurate and the carrying environment can be improved, therefore, the technical scheme can bring favorable economic benefit and environment-friendly effect and provide the guarantee for personnel safety and site safety.

Description

technical field [0001] The invention relates to equipment for starch packaging, in particular to an air extraction device for a starch packaging machine. Background technique [0002] First of all, since the materials are generally air-dried and sieved by vibrating screens in the production process, there will be a large amount of gas in the materials. During the packaging process, the gas will enter the packaging bag with the materials because it cannot be discharged. The process will cause dust to escape, which will cause air pollution, powder explosion and other hidden dangers. [0003] Secondly, due to the presence of a large amount of gas in the packaging bag, the density of the packaged material also changes. Therefore, the packaging material, that is, the packaging bag, needs to be enlarged. Phenomena such as loose stacking and rupture of packaging bags; the rupture of packaging bags has brought a lot of troubles to the storage of materials, which greatly affects the...

[0002] First of all, since the materials are generally air-dried and sieved by vibrating screens in the production process, there will be a large amount of gas in the materials. During the packaging process, the gas will enter the packaging bag with the materials because it cannot be discharged. The process will cause dust to escape, which will cause air pollution, powder explosion and other hidden dangers

[0003] Secondly, due to the presence of a large amount of gas in the packaging bag, the density of the packaged material also changes. Therefore, the packaging material, that is, the packaging bag, needs to be enlarged. Phenomena such as loose stacking and rupture of packaging bags; the rupture of packaging bags has brought a lot of troubles to the storage of materials, which greatly affects the warranty period of products; at the same time, due to the rupture of packaging bags, the materials will escape together with the gas in the packaging bags, The loss of materials will cause insufficient net weight of materials in the packaging bag, which will leave a bad impression on users
