Description

Technical Field

[0001] The utility model relates to the technical field of blow-fill-seal integrated machines, in particular to a container preparation device. Background Art

[0002] Combined with the existing blow-fill-seal technology, such as the production methods recorded in CN217895136U, CN115891112A and CN117261169A, continuous production is achieved by using a method in which the die head is stationary, the mold moves up and down, and the filling needle of the filling system moves up and down. After long-term operation of this method, the insoluble particles generated by the friction between the filling needle and the extrusion die head will fall into the container. To avoid this situation, the operator needs to clean the die head and the filling needle at regular intervals, and each disassembly and cleaning requires a lot of time and labor costs.

[0024] Preferably, the material blank extruded by the extrusion system 1 is continuous, the overall cross-section is elliptical, and the tension between the extruded material blank and the clamped mold or cooling clamp is constant, ensuring that the wall thickness of the material blank is uniform and wrinkle-free;

[0025] Preferably, a filling system 4 is provided above the extrusion die 15 of the extrusion system 1; a filling needle of the filling system 4 passes through the extrusion die 15 and is located in the continuously extruded material blank;

[0026] Preferably, a clamping mechanism 2 is provided below the extrusion die head 15, and the clamping mechanism 2 is mounted and fixed on the side panel of the frame 11;

[0033] A method for using a container preparation device comprises the following steps:

[0034] a. Control the cooling clamp mechanism 3 to rise to the inside of the mold, and then clamp the molded container (empty for the first time);

Control the cooling clamp mechanism 3 to descend, so that the left cooling clamp plate 33, the right cooling clamp plate 34 and the container move to the outside of the mold, and at the same time the extrusion die head 15 and the filling system 4 follow the descent, so that the embryo enters the inside of the mold, and the filling needle 41 is in place for filling;
