Embodiment Construction

[0034] The patent of the present invention provides a device that can detect and judge the airtightness of packaging bottles after sealing on the automatic packaging linkage line, and can automatically remove the packaging bottles that are judged to be unqualified from the linkage line. It is an indispensable device to ensure the quality of packaging sealing.

[0035] Device structure of the present invention sees figure 1 -3, as shown in the figure: it includes a positioning conveying mechanism 14 installed on the lower table 16 of the cabinet 1, a number of negative pressure detection mechanisms 12 installed on the positioning conveying mechanism 14 and a lifting mechanism 2 of the negative pressure detecting mechanism, See figure 1 . The positioning conveying mechanism 14 includes a conveyer belt 28 that is placed horizontally on the slideway and can move forward and backward under the action of the pusher 17. The chain plate of the conveyer belt 28 is equipped with a rep...

Abstract

The invention provides a device for on-line detection of the sealability of bottles, which comprises a locating conveying mechanism arranged on a lower table top on a chassis, a plurality of suction pressure detection mechanisms arranged on the locating conveying mechanism and an elevating mechanism for the suction pressure detection mechanisms. The positioning conveying mechanism comprises a conveyer belt which is arranged across a slideway as a whole and can shuttle under the action of a pusher. A plurality of partitioning locating pieces are arranged on the scraping belt of the conveyer belt. The conveyer belt is driven by a motor, and a moving guardrail is arranged on the position of the conveyer belt relative to the locating conveying mechanism. Each of the suction pressure detection mechanism comprises a metal cylinder, the wall of which is thick to some extent; the foundation ring plane of the metal cylinder is level, and is provided with an air leakage resistant seal ring; a universal thrust structure for a ball joint is arranged on the top of the cylinder. The elevating mechanism is used to adjust the suction pressure detection mechanisms to the positions suitable for detection. The invention can detect the airtightness of a plurality of bottles which have been packaged and sealed automatically, quickly and very efficiently, and determine whether the bottles are acceptable, and remove the acceptable bottles from the packaging linkage line.

Description

technical field [0001] The invention relates to the technical field of container leakage detection, in particular to a device for on-line detection of bottle sealing airtightness. Background technique [0002] As we all know, the bottles used in the packaging of medicines, beverages, etc. are usually recycled, that is to say, after the recycled bottles are cleaned, they will be repacked with products for sale. When we fill the bottle with medicine or beverage, the mouth of the bottle will be sealed to ensure the quality of the contents in the bottle. But, also do not have a kind of device that carries out on-line detection to the bottle after sealing at present. [0003] For example: Chinese invention patent CN1107971A provides a method for detecting the leakage of containers, especially recyclable plastic bottles, which is characterized in that some compressed liquid, such as compressed air, is poured into the container, Or empty the container; after filling or emptying, ...
