Description
Technical field
The invention belongs to beverage packaging pressure checking device field, the especially detection of negative pressure to PET heat filling beverage bottle.
Background technology
At present, PET bottle has become as the topmost packaged form of China's heat filling beverage, and beverage to be examined before hot filling
Survey bottleneck, bottle cap whether existing defects, bottle sealing etc., if defective meeting causes air to enter outside beverage, or beverage
Overflow.Affect the quality of product.Producing negative pressure in hot fill product bottle after cooling, the method for testing of test is single at present, only
It is by bottleneck internal pressurization, for soda pop etc., air pressure is injected in bottle, reach certain pressure, during pressurize one section
Between, to see that bottleneck is the most defective, and heat filling beverage is negative pressure, best detection method is to bottleneck external pressurized, the present invention
Being the external pressurized for bottleneck, see that gas arrives under certain pressure condition, whether gas can enter the device of beverage.
Summary of the invention
It is an object of the invention to provide a kind of can effectively heat filling beverage be tested under atmospheric environment mould
Material bottle negative-pressure detection device.
For solving above-mentioned technical problem, plastic bottle negative-pressure detection device of the present invention, including: base, described base sets
There is air inlet；Cavity, described cavity is arranged on described base, and described air inlet connects with described cavity；Water container, the described water capacity
Device is arranged on above described cavity；Fixed cell, described fixed cell is arranged between described cavity and described water container；And
Pneumatic means, described pneumatic means connects with described air inlet..
Preferably, it is additionally provided with sealing ring at described cavity and described water container on the contact surface with bottleneck to be measured.
Preferably, described fixed cell is active grab, and described active grab is arranged on the both sides of described bottleneck to be measured.
Preferably, described pneumatic means includes being sequentially connected with air compressor, relief valve, air accumulator, filter, decompression
Valve, flow control valve, Pressure gauge, rapid escape valve and acoustic filter.
Preferably, between described Pressure gauge and described rapid escape valve, a negative pressure device is also concatenated.
Plastic bottle negative-pressure detection device of the present invention is by negative pressure device to bottleneck external pressurized, and compressed air is led to as requested
Crossing air relief valve and enter pressure chamber applying pressure, make test specimens produce inside and outside differential pressure, the excessive situation of gas in observation sample, to judge
The sealing property of sample.

Detailed description of the invention
Below in conjunction with the accompanying drawings plastic bottle negative-pressure detection device of the present invention is described in further detail.
As it is shown in figure 1, plastic bottle negative-pressure detection device of the present invention, including: base 1, base 1 is provided with air inlet 2；Chamber
Body 3, cavity 3 is arranged on base 1, and air inlet 2 connects with cavity 3；Water container 4, water container 4 is arranged on above cavity 3；And it is fast
Speed clamp 5 is arranged on the both sides of bottleneck 17 to be measured.Cavity 3 and water container 4 with the contact surface of bottleneck 17 to be measured are additionally provided with close
Seal 6.
Pneumatic means is by connecting with air inlet, and pneumatic means includes the air compressor 7 being sequentially connected with, relief valve 8, stores up
Gas tank 9, filter 10, air relief valve 11, flow control valve 12, Pressure gauge 13, negative pressure device 14, rapid escape valve 15 and acoustic filter
16。
During work, first bottleneck 17 to be measured cutting is stayed 1/4, bottleneck 17 to be measured is put in the middle of water container 4 and pressure chamber, use
Active grab 5 clamps water container 4, and sealing ring 6 deforms and bottleneck 17 to be measured is carried out interior external seal simultaneously, water filling in water container 4,
Carry out stress test simultaneously.Test sample is defective, then there will be bubble in water container 4.As test sample need to be changed, first by water
Outwell, water container 4 is unclamped, sample can be taken out simultaneously.
Plastic bottle negative-pressure detection device of the present invention is by negative pressure device to bottleneck external pressurized, and compressed air is led to as requested
Crossing air relief valve and enter pressure chamber applying pressure, make test specimens produce inside and outside differential pressure, the excessive situation of gas in observation sample, to judge
The sealing property of sample.
Below preferred embodiment to the invention is illustrated, but the invention is not limited to described
Embodiment, those of ordinary skill in the art also can make all equivalents on the premise of the invention spirit
Modification or replacement, modification or the replacement of these equivalents are all contained in the application claim limited range.
