Patent document (CN 114835078 a) discloses a continuous production blowing, filling and sealing device and a method for using the same, which can continuously complete the processes of extrusion, molding, filling and sealing, and is beneficial to improving the production efficiency, and the blank is in a closed state in the whole production process, thereby avoiding the risk of pollution of the external environment to the filled liquid medicine. The use method can ensure that at least one part of the blank is always clamped and fixed by matching the upper clamping assembly with the lower clamping assembly in the whole production process, can effectively avoid the hidden danger of blank shaking caused by opening and closing the bottle head mould and the bottle body mould, and further ensures the uniformity of the product. However, in this scheme, the upper clamping assembly and the bottle head mold respectively act, that is, after the bottle head mold is closed, the blank is clamped by the upper clamping assembly, so that on one hand, the cycle of the whole cycle process is prolonged (the upper clamping assembly needs to wait for the blank to be clamped again after the bottle head mold is closed), which is not beneficial to further improving the production efficiency, and on the other hand, the bottle head mold and the upper clamping assembly can sequentially generate two times of impact on the blank, which is not beneficial to further maintaining the stability of the blank. The patent document (CN 104837603B) discloses an apparatus for manufacturing container products from plastic stock, which also clamps the blank after the sealing process is completed, and therefore still suffers from the above-mentioned drawbacks.

The continuous blow-potting apparatus of any of claims 4 to 8, wherein: the filling needle (3) comprises a filling needle body (31) and a filling needle seat (32) used for installing the filling needle body (31), a cooling sleeve (33) is arranged between the filling needle body (31) and the filling needle seat (32), and a through hole (34) is formed in the side wall of the lower end of the cooling sleeve (33).

10. The use method of the continuous blowing, filling and sealing equipment is characterized in that: the method comprises the following steps:

s1, extrusion: the plastic raw material is converted into plastic fluid by an extruder (1), and the plastic fluid is extruded into a blank body (10) by an extrusion die head (2);

s2, forming a bottle body: the bottle body forming mold (5) closes the mold and seals the bottom blank body (10) and forms the bottle body, and the second lifting mechanism (9) drives the sealing mold (4), the bottle body forming mold (5) and the upper clamping part (7) to synchronously descend along with the blank body (10);

s3, filling: the filling needle (3) descends to a set position for filling, and resets after filling is completed;

s4, sealing the bottle head: the sealing mold (4) is closed, meanwhile, the pushing piece (41) drives the upper clamping part (7) to clamp the blank body (10), and the second lifting mechanism (9) drives the sealing mold (4), the bottle body forming mold (5) and the upper clamping part (7) to synchronously descend along with the blank body (10);

s5, clamping the bottle body: the bottle body forming mold (5) is opened, the first lifting mechanism (8) drives the lower clamping part (6) to ascend into the bottle body forming mold (5) and then clamp the blank body (10);

s6, opening the sealing mold (4), keeping the upper clamping part (7) clamped, driving the lower clamping part (6) to synchronously descend along with the blank body (10) by the first lifting mechanism (8), and driving the sealing mold (4), the bottle body forming mold (5) and the upper clamping part (7) to synchronously descend to a set position along with the blank body (10) by the second lifting mechanism (9);

s7, resetting: the upper clamping part (7) is opened, the second lifting mechanism (9) drives the sealing mould (4), the bottle body forming mould (5) and the upper clamping part (7) to ascend to the initial position, the lower clamping part (6) keeps clamping, and the first lifting mechanism (8) drives the lower clamping part (6) to descend synchronously along with the blank body;

and S8, circularly performing the steps S2 to S7 until the production or the fault shutdown is finished.
