Abstract
The invention relates to a rotary plastic container leak tester. The leak tester comprises a rack and is characterized in that a leak testing rotating plate device is arranged on the rack; and a rotating plate and a plurality of bubble collection devices are arranged on the leak testing rotating plate device. The bubble collection devices are arranged at corresponding positions of the rotating plate; and the bubble collection devices and the rotating plate form a plurality of container fixation stations. Besides, a speed reducer is also arranged at the bottom of the rack and is connected with the leak testing rotating plate device by a rotating shaft; and the leak testing rotating plate device is driven to make rotary motion. On the basis of the structure, a plastic container is extruded by an extrusion assembly to increase the air pressure in the plastic container and thus the air leaks from micropores of the connecting part of the plastic container sealing cover; with collection and viewing of the bubble collection devices, whether the plastic container is sealed well can be identified. Therefore, whether a leakage defect exists in the plastic container can be detected rapidly and precisely and thus the labor intensity of the worker can be reduced.
Description
Technical field
The present invention relates to a kind of plastic packaging containers checkout equipment, especially a kind of rotary plastic material container air leak tester.
Background technology
Leak hunting and be the abbreviation of " detect and leak " and " monitoring leakage ", refers to that employing professional method and instrument check the production equipment such as pipeline, storage tank, device or utensil, find whether it exists leakage, orient leakage point particular location, and provide leakage rate.In beverage syrup industry, packing container side leakage is that whether qualified inspecting containers produce a important indicator, and beverage packaging unit leakage can cause the loss of beverage, also can pollute the daily necessities such as clothes, case and bag, for user makes troubles simultaneously.
Existing plastic containers leak detecting device detects the change of liquid level after generally adopting extruding, or whether the process detection bottle of extruding detects beverage bottle to outside reacting force change and leaks, minimum defect area must be greater than 0.2mm2, these detection means accuracys are not high, and detection method is all very high to the requirement of equipment software and hardware, not intuitively.There will be undetected situation for very micro-leakage especially, this directly causes substandard product to come into the market infringement business and consumer interests.
Summary of the invention
The object of this invention is to provide a kind of structure simple, accuracy of detection is high, and detect directly perceived, detection efficiency is high, the rotary plastic material container air leak tester of failure rate is low.
Realize above-mentioned purpose, the technical solution adopted in the present invention is: rotary plastic material container air leak tester, comprise: frame, it is characterized in that: in frame, be provided with the rotating-table apparatus that leaks hunting, the described rotating-table apparatus that leaks hunting is provided with rotating disk and several bubble collecting devices, this bubble collecting device is located on the correspondence position of rotating disk, and station fixed by several containers of the formation of bubble collecting device and rotating disk; Bottom described frame, be also provided with reductor, this reductor is connected with the rotating-table apparatus that leaks hunting by rotating shaft, and drives the rotating-table apparatus that leaks hunting to do gyration.
Preferably, the described rotating-table apparatus that leaks hunting is made up of rotating disk, cam mechanism, bubble collecting device and pressing mechanism, cam mechanism is fixedly mounted on rotating disk, rotating disk is fixedly connected with the rotating shaft on reductor, bubble collecting device is connected with cam mechanism by cam follower, and does upper and lower displacement along the anglec of rotation change of cam mechanism; Pressing mechanism is located at rotating disk outer side edges edge, and it is corresponding that station fixed by its position and container.
Preferably, described bubble collecting device is socketed by O-ring seal and plastic containers and seals, and the side of bubble collecting device is provided with water filling port, and the top of bubble collecting device is provided with one-way exhaust valve.
Preferably, the described rotating-table apparatus that leaks hunting is provided with industrial camera near the side of bottle outlet, and the position of this industrial camera is corresponding with the position of bubble collecting device.
Preferably, described pressing mechanism is squeezing passage, and the distance size of this squeezing passage is less than the size of plastic containers.
Present external state-of-the-art detection gimmick has the pressure change 1. judged the height of liquid level in container by extruding in 2. inspection instrument, the minimum defect that these two kinds of detection meanss can detect all is greater than 0.2mm2, and the testing process time very short (2-3 second) easily causes undetected.This patent utilizes extruding to produce the method for bubble, and advantage is very micro-leakage to be reflected very intuitively by physical phenomenon, and method simple operations is convenient, detects the technology maturation of bubble with industrial camera, is conducive to reducing business capital burden.On the other hand by extending the detection time (being greater than more than 5 seconds) of single container, long-time extruding is applied to container, the defect making this patent detect can be less than 0.02mm2 even can still have the container of disclosure risk to find in advance to reject non-defectiveness, really accomplishes to take precautions against in possible trouble.
After the present invention adopts said structure, by adopting compression assemblies, plastic containers are extruded, atmospheric pressure in plastic containers is increased, air is forced to ooze out from the micropore of sealing cap for plastic container junction, and inspected by the collection of bubble collecting device, thus tell the frame mode that plastic containers seal whether existing defects, achieve fast, precisely detect the problem whether plastic containers exist leakage defect, alleviate the labour intensity of staff.Structure of the present invention is simple, and accuracy of detection is high, and detect directly perceived, detection efficiency is high, failure rate is low.
