Plastic bottle vacuum leak detection and leak detection ridding mechanism

Abstract

A plastic bottle vacuum leak detection and leak detection ridding mechanism comprises a vacuum leak detection mould device (1), a vacuum bilge board (3) and a stock guide plate (7), wherein the vacuum bilge board (3) is slantly arranged relative to the horizontal direction; the inclination angle of the vacuum bilge board (3) relative to the horizontal direction is an inclination angle selected by taking the fact that the liquid in the plastic bottle is ensured not to reach a shoulder-neck as a standard; the leak detection station of the vacuum leak detection mould device (1) is corresponding to the position of the vacuum bilge board (3); the vacuum leak detection mould device (1) is matched with the vacuum bilge board (3) to form a vacuum chamber; the stock guide plate (7) is arranged in the inclination angle direction of the vacuum bilge board (3), and can swing corresponding to the vacuum bilge board (3). The mechanism effectively enhances the leak detection accuracy rate, and simplifies the structure and the movement of a waste ridding device.

Description

technical field [0001] The invention relates to the field of food and pharmaceutical packaging machinery, in particular to a plastic bottle vacuum leak detection and leak detection and rejection mechanism used in a product blow-fill-seal integrated machine. Background technique [0002] In pharmaceutical packaging equipment, there are generally devices used to detect and reject unqualified products. At present, there is a vacuum leak detection and leak detection and rejection mechanism for plastic bottles, which mainly includes a vacuum leak detection mold device, a movable suction bottle block, and a vacuum chamber. Bottom plate, waste bottle material guide plate, when the product is separated from the remaining material, the blanking die is opened, the product is absorbed by the vacuum in the movable suction bottle block and rotates to the vertical axis together with the entire movable vacuum leak detection die. At the same time, the entire movable vacuum leak detection mo...

Problems solved by technology

[0003] In the state of leak detection, the entire movable vacuum leak detection mold is turned to the vertical position. At this time, the product is in the horizontal position, and the leaking part of the container mainly occurs at the shoulder of the bottle. During the vacuum leak detection, the product in the horizontal product container Liquids are prone to leakage, resulting in the same vacuum degree in the product as in the vacuum chamber. After a preset time, the vacuum degree in the vacuum chamber will still remain within the allowable range, resulting in misjudgment and affecting the accuracy of leak detection At the same time, when rejecting qualified and unqualified products and restoring the device, it is necessary to go through several stages of the leak detection cylinder driving the bottom plate of the vacuum cabin to move left and right, the waste bottle guide plate to block the product movement, and the waste bottle guide plate to lift. The structure and action are more complicated
