Problems solved by technology
[0002] Some products need to judge its airtightness. The existing technology generally uses manual inspection, which is time-consuming and labor-intensive, which increases the production cost and labor intensity. Therefore, it is necessary to design an airtightness testing mechanism, which uses a silicone pressure head to pass through the power source. It is attached to the air inlet of the product. After the silicone pressure head is attached to the product, the product is vacuumed. When the negative pressure value in the product reaches the set predetermined value, the vacuum is stopped, and the negative pressure in the product is detected. Judging the tightness of the product

The invention relates to an air tightness testing mechanism. A bottom plate is disposed in a rack, which is provided with a vacuumizing mechanism. The bottom part of the bottom plate is provided with a driving device, and the upper part of the bottom plate is slidably provided with a carrier fixing plate, which is provided with a carrier. The vertical plate of the driving device passes through the bottom plate, and the upper end of the vertical plate is connected with the carrier fixing plate, and in addition, the driving device is used to drive the carrier to move. The bottom plate is connected with a pressing cylinder fixing plate by four guiding pillars a, and the lower part of the pressing cylinder fixing plate is provided with a pressing cylinder. The lower end of the pressing cylinder is connected with a movable plate, the lower part of which is provided with a pressing plate by an equal-height screw. The lower part of the pressing plate is provided with a silicone pressing head. The air tightness testing mechanism is advantageous in that under the driving of the pressing cylinder, the silicone pressing head can be attached to the gas inlet opening of the product, and thereafter the product can be vacuumized; when the negative pressure value in the product reaches the preset value, the vacuumizing can be stopped; the sealing performance of the product can be determined by detecting the negative pressure in the product, and therefore the mechanism is simple and practical, the costs can be saved, and the mechanism is suitable for the air tightness detection of various products.
