Embodiment
Be used to detect the checkout equipment that hard shell capsules is sealed sealing, be hard shell capsules to be immersed in the salad wet goods that places the transparent vacuum container detect the equipment whether medium observation has bubble to produce, this equipment comprises: sight chamber 1 and be used for described sight chamber 1 is evacuated to the vacuum generator spare of negative pressure, described vacuum device is connected with digital display vacuum control device 2 so that show and the Control work constant pressure.As shown in the figure.Sight chamber 1 comprises able to turn on or off airtight transparent vessel 3, places one in it and is loaded with soybean oil as the transparent vessel 4 that detects medium.In transparent vessel 4, be mounted with capsule anchor clamps 5 with the clamping hard shell capsules.
For reaching ideal effect, in the present invention, able to turn on or off airtight transparent vessel 3 is a casing, and obviously preferred design becomes cylinder, and the upper end is provided with lid 6, and the lower end is provided with through hole 7.
Vacuum generator spare comprises vacuum pump 8, tracheae 9, and tracheae is sealedly connected between the through hole 7 and vacuum pump 8 of able to turn on or off airtight transparent vessel 3, and inter-burst is connected to solenoid valve A10 so that control the interior negative pressure value of described airtight transparent vessel.
In application process owing to will take out capsule anchor clamps 5 to fold up tested hard shell capsules frequently, this just needs the air pressure balance ability uncap 6 in the airtight transparent vessel 3 of recovery, so, tracheae 9 also is provided with a relief port 11, and is connected in series solenoid valve B12 so that control described airtight transparent vessel internal gas pressure balance at the relief port place.
During detection, at first injecting kinetic viscosity at transparent vessel 4 is 2-500mpa.s, can be transparent soybean oil or other vegetable oil, animal oil, the chemistry wet goods detects medium, use the tested hard shell capsules of capsule anchor clamps 5 clampings again, and extension is fixed in the transparent vessel 4, the concrete degree of depth detects in the medium to guarantee that its folded hard shell capsules can be immersed in, place it in then in the able to turn on or off airtight transparent vessel 3, cover lid 6 gives airtight and starts vacuum pump 8 will being evacuated to negative pressure in the airtight transparent vessel 3 for any one numerical value between the-0.001--0.05Mpa and keep the constant 5-30 of this working pressure second by tracheae.
Observation detection medium has or not bubble to produce during this period, if there is bubble to produce, shows the blow-by of sealing of detected hard shell capsules, and is undesirable, otherwise then meets the sealing property requirement.
When detection finished, solenoid valve B12 opened, and relief port 11 paths restore balance airtight transparent vessel 3 internal gas pressures, just can take out tested capsule with unlatching.
