Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1~2, in the embodiment of the present invention, a kind of blow-molded article forming process gas leakage detection machine, including gas stream
Quantity sensor 1, PLC controller 2, warning device 3, touch screen 4, air blowing air valve 5, blow mold 6, tracheae 7 and data cable 8,
It is connected with tracheae 7 on the blow mold 6, gas flow sensor 1 and air blowing air valve 5 are separately installed on tracheae 7, it is described
PLC controller 2 is electrically connected with warning device 3, touch screen 4 and gas flow sensor 1 respectively by data cable 8, described
Gas flow sensor 1 is used to detect the flow of production process compressed air and sends data to PLC controller 2, the PLC control
The data that device 2 processed is used to transmit gas flow sensor 1 are handled, and to judge the case where product is with the presence or absence of gas leakage, are had
Gas leakage situation can also send a signal to warning device 3, and the touch screen 4 can monitor current shape for setting parameters
State, or parameters are set using other " man-machine interfaces ", for prompting operator, product has occurred the warning device 3
Gas leakage situation, defective products will distinguish, and the air blowing air valve 5 is used to that product is inflated and is deflated, and be exactly that machine is included
Air valve, have no need to install.
In the present embodiment, the gas flow sensor 1 is installed on the tracheae 7 between air blowing air valve 5 and blow mold 6
On.
In the present embodiment, the warning device 3 is combined aural and visual alarm.
In the present embodiment, the PLC controller 2, warning device 3 and touch screen 4 are installed on the electronic box of blow moulding machine.
The art production process of the blow mold 6 are as follows: first step extruded stock embryo；Second step closes up mold；Third step is past
Model cavity is filled with compressed air, keeps certain time product cooling；Compressed air is discharged in 4th step, opens mold and takes out product.
The present invention is achieved by the following technical solutions: in production process third step, to the flow of mold cavity inflation
It is monitored in real time with gas flow sensor 1.Just starting to have a bigger flow when inflation, after air is completely filled with
Gastight product flow can stablize a relatively low value (fixed minor leakage existing for each 7 connector of tracheae tracheae), this
When the data on flows that receives of PLC controller 2 be less than setting flow and will not trigger warning device 3, if a certain in production process
The flow value of a product is greater than this value, the data transmission that at this moment gas flow sensor 1 issues to PLC controller 2, PLC control
Device 2 processed compares actual flow and there is gas leak phenomenon as defective products greater than flow is set, and then 2 output signal of PLC controller is touched
Alarm device 3 transmit messages to prompt operator, realizes defective products detection in process of production.
The blow-molded article forming process gas leakage detection machine, installation are simple, it is only necessary to a gas is concatenated in blowing pipe
Flow sensor 1, PLC controller 2, warning device 3 and touch screen 4 can be installed on existing electronic box；It is passed with gas flow
Sensor 1, PLC controller 2 and touch screen 4 data total digitalization, parameter setting intuitive and convenient detect reliable and stable；It is versatile,
Installing a set of can reliably detect all molds and product, it is not necessary to individually dedicated to develop for every kind of product
" frock clamp ", reduces production cost；The time is saved, is improved efficiency, production process, that is, detection process, after the completion of removing product from
Time-consuming and laborious equal adverse effect brought by being detected again；The configuration of the present invention is simple detects reliable and stable, suitable popularization.
