Description

Technical Field

[0001] The utility model relates to the technical field of vacuum hot pressing forming machines, in particular to an air collecting and filtering device of a vacuum hot pressing forming machine. Background Art

[0002] The vacuum hot pressing machine heats the material first when working. When the molding temperature is reached, the vacuum cover at the upper end is lowered to cover the material. At the same time, the material is deformed under the adsorption of vacuum to achieve the effect of the finished product. The vacuum is achieved by evacuating the air through the pump body.

[0003] However, when the pump body is evacuating the air, the gas is filtered through the filter box. After filtering, foreign matter can be prevented from entering the pump body, and the efficiency of the pump body can be guaranteed. The filter element in the traditional filter box is fixed, and the filtering position of the filter element is only at the air inlet. After using it for a period of time, the filter element needs to be replaced and cleaned, while the filtering surfaces of other parts of the filter element can continue to work, which reduces the overall filtering effect.
