Description
Technical field
The utility model relates to a kind of control circuit, relates in particular to a kind of PET injection molding needle controller.
Background technology
PET, promptly PETG is a kind of plastic material relatively more commonly used at present, has the transparency height, nontoxic, tasteless, wholesomeness is good, advantages such as good mechanical properties.The PET bottle day by day replaces PVC bottle, bag, aluminium pot, and iron flask, vials etc. become the packing timber of tool growth potentiality.But in the injection moulding of existing P ET bottle is produced, because injection time is uncontrollable, cause through regular meeting that turn white in a bottle embryo bottom, problems such as grog phenomenon appear in a bottle embryo body, product qualified rate is low, but also needs to increase the operation of hammer-shears embryo.
The utility model content
To the deficiency of above-mentioned prior art, the technical problem that the utility model will solve provides a kind of controller of when injection moulding, controlling the needle working time.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: 1, a kind of PET injection molding needle controller is characterized in that: comprise very first time relay, second time relay, first auxiliary reclay, second auxiliary reclay; The coil crossover of very first time relay is between melten gel signal positive input terminal and melten gel signal negative input end; Melten gel signal positive input terminal is connected with first auxiliary reclay through the switch of very first time relay, and the other end of first auxiliary reclay is connected with power cathode; Positive source is connected to the control signal output through the switch of first auxiliary reclay; The two ends of the switch in parallel of second auxiliary reclay switch of device in the middle of first; The coil crossover of second time relay is between control signal output and power cathode; The switch series of the coil of second auxiliary reclay and second time relay is unified into branch road, and this branch road is connected in parallel on the two ends of the coil of second time relay.The magnetic valve of needle is connected across between control signal output and the power cathode, realizes the control to the needle duty by the control signal output, and the coil of each relay is controlled the closed situation of disconnection of switch separately respectively.Such structure makes the working time of needle can realize automatic control, and turn white in bottle embryo bottom, the problem of bottle embryo body imitation frosted glass thereby improve.
A kind of preferred as the utility model; Also be connected with a single-pole double-throw switch (SPDT) between the switch of first auxiliary reclay and the positive source; The not moved end of single-pole double-throw switch (SPDT) is connected with positive source; One of them moved end is connected with the switch of first auxiliary reclay, and another moved end is connected with the control signal output.Such structure makes PET injection molding needle controller have automatic control and manually controls two kinds of patterns, when the electric elements fault, still can guarantee production efficiency earlier.
In sum, the PET injection molding needle controller of the utility model can be adjusted the needle working time, solves that turn white in bottle embryo bottom, the problem of bottle embryo body imitation frosted glass, the operation of removing the hammer-shears embryo from, and improve the qualification rate of product greatly.
