As shown in Fig. 2, when floating piston is against on annular upper limit position block, the second venthole is located at floating with third venthole The lower section of piston.
When floating piston is against on annular lower position block, the second venthole is located at the upper of floating piston with third venthole Side.
As shown in Figure 1, when floating support plate is against on the second limited block:First venthole is located under floating sliding sleeve Side.
When floating support plate is against on the first limited block:First venthole be located at lower seal in floating sliding sleeve with it is upper Between sealing ring.
The specific works of the air-tightness detection device of the food cans of the present embodiment are as follows:
The original state of the air-tightness detection device of food cans, as shown in Figure 1, at this point, third limited block is against leads vertically On the lower face of set, floating piston is against on annular upper limit position block, and floating support plate is against on the second limited block.
First, food cans 4 are placed in food cans locating slot, the upper port of food cans is positioned by food cans upward Slot positions food cans, as shown in Figure 3.
Second, lifting cylinder drives floating support plate to move down, in this process:
Horizontal pressure foot, vertical guide rod, end face seal gasket, sealing cylinder will be erected with vertical pressure inlet in Gravitative Loads lower edge Straight guide sleeve moves down, and when end face seal gasket is against on the upper surface of food cans, horizontal pressure foot, vertical guide rod, end face are close Gasket, sealing cylinder and the stopping of vertical pressure inlet move down, at this point, sealing cylinder is located at food cans with air pressure detection sensor In upper port(The outer diameter for sealing cylinder is less than the internal diameter of food cans);
Then, lifting cylinder drives floating support plate to continue to move down, in this process:Floating sliding sleeve is along vertical pressure inlet It moving down, after floating support plate is against on the first limited block, lifting cylinder drives floating support plate to continue to move down 1 millimeter, Then lifting cylinder is stopped, at this time:First venthole is located at the lower seal in floating sliding sleeve and between upper sealing ring, the One venthole is not in communication with the outside, and end face seal gasket is pressed on the upper surface of food cans, end face seal gasket and food First of sealing is formed between the upper surface of product tank(End face seal).
Third opens switch valve, is pressurized pump work, is inflated in vertical pressure inlet by booster pump and connecting tube, at this During a:
Floating piston in vertical pressure inlet moves down first, when floating sliding sleeve be located at the second venthole and third venthole it Between when, inflation inner cavity will be entered by the second venthole by being pressurized the gas that is pumped into vertical pressure inlet, and sealing cylinder is made to expand And be against on the medial surface of food cans, in the medial surface of sealing cylinder and food cans(Medial surface close to food cans upper end) Between formed second sealing(Medial surface seals);
Then, floating piston continues to move down, until floating piston is against on annular lower position block, at this point, booster pump The gas being pressed into vertical pressure inlet will be entered by third venthole in food cans;When baroceptor detects in food cans Air pressure when reaching setting value P1, switch valve is closed, and booster pump is stopped, and after food cans pressurize 6 seconds, then passes through air pressure Sensor detects the air pressure P2 in food cans;
Followed by two draught head △ P, △ P=P1- P2 of calculating;
If △ P are less than setting value, illustrate that canned food air-tightness meets the requirements;
If △ P are greater than the set value, illustrate that canned food air-tightness is undesirable.
In addition, in this process, due to forming first of sealing between end face seal gasket and the upper surface of food cans, It seals and forms second sealing between cylinder and the medial surface of food cans, can ensure in food cans pressure maintaining period in this way, eat Gas in product tank will not be bad because of the sealing effect between end face seal gasket and food cans, generates gas leakage, and causes △ P big In setting value, the problem of erroneous judgement by accident, the detection accuracy of the air-tightness of food cans is effectively improved.
4th, lifting cylinder drives floating support plate to move up, in this process:
Floating support plate and floating sliding sleeve will be moved up first(Horizontal pressure foot, vertical guide rod, end face seal gasket, sealing cylinder It is kept essentially stationary with vertical pressure inlet), when the first venthole is located at the lower section of floating sliding sleeve, the first venthole connects with extraneous It is logical, to make the gas of intracavitary in inflation pass through the second venthole, vertical pressure inlet and the discharge of the first venthole, to make sealing Cylinder shrinks and is detached with food cans;After floating support plate is against on the second limited block, floating support strip move horizontal pressure foot, Vertical guide rod, end face seal gasket, sealing cylinder up move in place together with vertical pressure inlet;Meanwhile floating piston is in work It up moves, reset under the action of plug resetting spring;
Since sealing cylinder is shunk and is detached with food cans, in this way after floating support plate is against on the second limited block, float Dynamic support plate drives horizontal pressure foot, vertical guide rod, end face seal gasket, sealing cylinder up to be moved together with vertical pressure inlet In the process, food cans will not be driven to move up together(Sealing cylinder contraction is detached with food cans), seal cylinder and food cans be smooth Separation ensures that the food cans for completing air-leakage test can smoothly be taken out.
5th, take out the food cans for completing air-leakage test.
