Before formal production and filling of the blowing, filling and sealing integrated machine, a product flow channel of the equipment needs to be sterilized by high-temperature steam, in order to quickly heat up, shorten the heating time and improve the sterilization efficiency, the high-temperature steam needs to be introduced into the temperature control joint 8 to accelerate the heating of the whole container filling mechanism, after the sterilization process is completed, the whole container filling mechanism is still in a higher temperature state, and in order to not influence the property of the filled product, a cooling medium needs to be introduced into the temperature control joint 8 to cool the whole container filling mechanism; after the steps are finished, high-point air exhaust is needed before formal filling of the product to improve the filling precision, and the specific operation is that after the filling product enters the liquid medicine distribution block 2 from the liquid inlet pipe 1, the liquid medicine control switch seat 10 at the downstream is in a closed state, namely, the filled product cannot flow into the hollow filling needle 13, and the high-point air exhaust joint 3 is in an open state at the moment, so that the air in the product before filling is started can burst to the high point until the air is completely exhausted (Chinese patent No. CN 202021040945.3); after the steps are completed, when formal products are filled, the high-point exhaust connector 3 is closed, the liquid medicine control switch base 10 at the downstream is opened (air pressure in the air passage I19 at the upper end of the control membrane mounting plate 9 is switched from positive pressure to negative pressure, the negative pressure sucks the liquid medicine control membrane I11, so that a product flow passage of the liquid medicine control switch base 10 is opened), the suck-back point at the lower part of the liquid medicine control valve block 5 is in a closed state (air pressure in the air passage II 20 at the lower end of the control membrane mounting plate 9 is switched from negative pressure to positive pressure, and the liquid medicine control membrane II 18 is propped against the suck-back point of the liquid medicine control valve block 5 by the positive pressure), and the filled products can normally flow to the hollow filling needle 13 from the liquid inlet pipe 1 at the moment, so that the filling of the products is realized;
after the product is filled, the liquid medicine control switch seat 10 at the lower part is closed (the air pressure in the air passage I19 at the upper end of the control diaphragm mounting plate 9 is switched from negative pressure to positive pressure, the liquid medicine control diaphragm I11 is propped against the liquid medicine control switch seat 10 during the positive pressure, so that a product flow passage of the liquid medicine control switch seat 10 is closed), the suck-back point at the lower part of the liquid medicine control valve block 5 is in an open state (the air pressure in the air passage II 20 at the lower end of the control diaphragm mounting plate 9 is switched from positive pressure to negative pressure, and the liquid medicine control diaphragm II 18 is sucked back by the negative pressure), so as to suck back the product at the upper end of the needle tube of the filling needle 13 and prevent the generation of liquid dropping; when the product is filled, in order to protect the filled product (anaerobic product and the like), protective gas needs to be filled during product filling, the protective gas enters the upper part of the blowing needle 14 from the gas inlet connector 12, enters the gap between the filling needle 13 and the blowing needle 14 through the opening of the blowing needle 14, then enters the bottle blank along with the product during product filling, and the protective gas and the filled product are combined together after the bottle blank is sealed to protect the product.
The specific on-off control mode of the product flow channel is as follows: the position where the liquid medicine control switch base 10 and the liquid medicine control membrane one 11 are contacted is a product flow channel control point 25 (as shown in fig. 7, there are 3 control points), when positive pressure air flow is introduced into the air passage one 19, the liquid medicine control membrane one 11 deforms leftwards, the product flow channel control point at the position where the liquid medicine control switch base 10 and the liquid medicine control membrane one 11 are contacted is blocked and closed, so that the upstream flow channel 23 of the control point and the downstream flow channel 24 of the control point are not communicated; when negative pressure airflow is introduced into the air passage I19, the liquid medicine control membrane I11 generates rightward deformation, so that a product flow passage control point at the contact position of the liquid medicine control switch seat 10 and the liquid medicine control membrane I11 is opened, and the control point upstream flow passage 23 is communicated with the control point downstream flow passage 24; the product flow channel is switched on and off through the operation (as shown in figure 7).
