A bottle body positioning groove 62 is arranged on the inner side of the clamping plate 61, a bottle head positioning groove 63 is arranged below the bottle body positioning groove 62, and cooling channels 64 are arranged on the sides of the bottle body positioning groove 62 and the bottle head positioning groove 63. Taking the first lifting mechanism 8 as an example, in this embodiment, the first lifting mechanism 8 includes a servo motor 81, a ball screw 82 connected to the servo motor 81, and a screw nut 83 arranged on the ball screw 82. The lower clamping assembly 6 is connected to the screw nut 83. When in use, the servo motor 81 drives the ball screw 82 to rotate, and the screw nut 83 moves up and down on the ball screw 82. The lower clamping assembly 6 is lifted and lowered synchronously with the screw nut 83. The overall structure is simple, reliable, and has high motion accuracy. Of course, in other embodiments, the first lifting mechanism 8 can also adopt other forms. The second lifting mechanism 9 can have the same structure as the first lifting mechanism 8, which will not be repeated.

[0039] The continuous production blowing, filling and sealing equipment can continuously complete the extrusion, molding, filling and sealing processes, which is beneficial to improving production efficiency. In the entire production process, the embryo 10 is in a closed state, avoiding the risk of contamination of the filling liquid by the external environment. Driven by the first lifting mechanism 8, the lower clamping component 6 can rise between the bottle body mold 5 (after the bottle body mold 5 is opened) and clamp and fix the bottle body of the upper bottle body 20 and the bottle head of the lower bottle body 20 at the same time, effectively avoiding the shaking of the embryo 10 when the bottle head mold 4 and the bottle body mold 5 are opened and closed, and the coolant introduced into the cooling channel 64 in the clamping plate 61 can cool the formed bottle body 20, which is beneficial to ensure the consistency of the bottle body 20.

[0040] Furthermore, in this embodiment, an upper clamping assembly 7 is provided above the bottle head mold 4, and the upper clamping assembly 7 is provided on the second lifting mechanism 9. The upper clamping assembly 7 cooperates with the lower clamping assembly 6 to ensure that the embryo 10 is always clamped and fixed at least at one place, and the hidden danger of the embryo 10 shaking when the bottle head mold 4 and the bottle body mold 5 are opened and closed during the entire production process can be effectively avoided, further improving the reliability of the equipment.

[0041] As a preferred embodiment, the continuous production blow-fill-seal equipment further includes an air supply component (not shown in the figure, such as a blower, an air supply pipeline, etc.) for providing clean air to the area where the extrusion die head 2 is located. The air supply component provides clean oxygen-free gas (such as nitrogen or inert gas, etc.) to the area where the extrusion die head 2 is located, thereby ensuring a sterile, oxygen-free and clean environment during the molding, filling and sealing processes.

[0042] Furthermore, in this embodiment, the clamping plate 61 is connected to a first telescopic driving member 65 (such as a cylinder, an electric cylinder, a screw nut pair, etc.) and a first guide rod 66, and the first guide rod 66 is inserted into a first guide seat 67. The first guide rod 66 cooperates with the first guide seat 67 to provide a guide for the opening and closing action of the clamping plate 61, which is conducive to ensuring the smoothness and accuracy of the movement process.

[0043] Furthermore, in this embodiment, the upper clamping assembly 7 includes a pair of wedge-shaped clamping blocks 71, which are connected to a second telescopic driving member 73 (such as a cylinder, an electric cylinder, a screw nut pair, etc.) through a second guide rod 72, and the second guide rod 72 is inserted into a second guide seat 74. The wedge-shaped clamping block 71 has high mechanical strength, and the thinner side is convenient for clamping the embryo 10 to reduce material waste, and the thicker side is convenient for connecting the second guide rod 72. The second guide rod 72 cooperates with the second guide seat 74 to provide a guide for the opening and closing action of the wedge-shaped clamping block 71, which is conducive to ensuring the smoothness and accuracy of the movement process.

[0044] Furthermore, in this embodiment, the injection needle 3 includes an injection needle body 31 and an injection needle seat 32 for mounting the injection needle body 31. A cooling sleeve 33 is provided between the injection needle body 31 and the injection needle seat 32. A through hole 34 is provided on the side wall at the lower end of the cooling sleeve 33. Cooling liquid can be introduced into the cooling sleeve 33, flows downward and then flows out from the through hole 34, and finally leaves the injection needle seat 32 from the gap between the cooling sleeve 33 and the injection needle seat 32. During the flow process, the liquid medicine in the injection needle body 31 can be kept warm to avoid the adverse effect of the high temperature embryo 10 on the liquid medicine.

[0045] Embodiment 2

In the method for using the continuous production blow-fill-seal equipment of this embodiment, the extruder 1 extrude the embryo 10, the lower clamping assembly 6 rises to the bottle body mold 5 to seal the bottom embryo 10 and moves downward, the bottle body mold 5 and the bottle head mold 4 form the bottle body and the bottle head of the embryo 10, and at the same time, the lower clamping assembly 6, the bottle head mold 4 and the bottle body mold 5 descend synchronously, and after the bottle body mold 5 is opened and before the bottle head mold 4 is opened, the lower clamping assembly 6 rises to the bottle body mold 5 to clamp the bottle body 20.

[0047] The method for using the continuous production blowing, filling and sealing equipment continuously performs extrusion, molding, filling and sealing processes, thereby improving production efficiency. In the entire production process, the embryo 10 is in a closed state, thereby avoiding the risk of contamination of the filling liquid by the external environment. The lower clamping component 6 rises between the bottle body mold 5 to clamp and fix the bottle body 20, thereby effectively avoiding the shaking of the embryo 10 when the bottle head mold 4 and the bottle body mold 5 are opened and closed.

[0048] In this embodiment, the specific steps of the method for using the continuous production blow-fill-seal equipment are as follows:

[0049] S1. Extrusion: The extruder 1 converts the plastic raw material into a plastic fluid, and the extrusion die 2 extrude the plastic fluid into an embryo 10. For details, see Figure 7 In this embodiment, the embryo body 10 has a cross-section of a round closed structure;

[0050] S2, the embryo 10 is sealed at the bottom: the first lifting mechanism 8 drives the lower clamping assembly 6 to rise to the bottle body mold 5 (the bottle body mold 5 has not yet been closed), the lower clamping assembly 6 clamps the embryo 10, and the first lifting mechanism 8 drives the lower clamping assembly 6 to descend to the initial position synchronously with the embryo 10 ( Figure 8 In a, P0 is the initial position of the lower clamping assembly 6, and P0′ is the initial position of the bottle head mold 4, which is also the highest position. Figure 8 P1 in b is the position where the lower clamping assembly 6 rises to the bottle body mold 5, which is also the highest position of the lower clamping assembly 6. Figure 8 a to Figure 8 As shown in c;

[0051] S3, bottle body forming: the bottle body mold 5 is closed and descends synchronously with the embryo 10 to form the bottle body, and the filling needle 3 descends to the set position for filling. Figure 8 As shown in d, it is reset after filling is completed;

[0052] S4, bottle head forming: the bottle head mold 4 is molded to form the bottle head, the first lifting mechanism 8 drives the lower clamping assembly 6, and the second lifting mechanism 9 drives the bottle head mold 4 and the bottle body mold 5 to synchronously descend to the set position along with the embryo 10. Figure 8 e to Figure 8 As shown in g, Figure 8 In g, the bottle head mold 4 is located at the P1′ position, and the lower clamping assembly 6 is located at the P2 position, both of which are at the lowest position;

[0053] S5, clamping the embryo 10: the bottle body mold 5 is opened, the first lifting mechanism 8 drives the lower clamping assembly 6 to rise between the bottle body mold 5, the lower clamping assembly 6 clamps the formed bottle body 20, and the bottle head mold 4 is opened. Figure 8 g to Figure 8 As shown in FIG. 1 , it should be noted that, for the first row of bottles 20 formed, the lower clamping assembly 6 only clamps the first row of bottles 20. In the subsequent process, the lower clamping assembly 6 simultaneously clamps the bottle bodies of the upper row of bottles 20 and the bottle heads of the lower row of bottles 20, or in other words, simultaneously clamps the bottle heads of the previous cycle of bottles 20 and the bottle bodies of the current cycle of bottles 20;

[0054] S6, reset: the second lifting mechanism 9 drives the bottle head mold 4 and the bottle body mold 5 to rise to the initial position, and the first lifting mechanism 8 drives the lower clamping assembly 6 to move to the initial position. Figure 8 k to Figure 8 As shown in l, Figure 8 l and Figure 8 The devices in d are in the same state;

[0055] S7. Repeat steps S3 to S6 until production is completed or the machine is shut down due to a fault.

[0056] Further, in this embodiment, when the lower clamping assembly 6 is located below the bottle body mold 5, the maximum distance between the lower clamping assembly 6 and the bottle body mold 5 is greater than the length of the bottle head. Figure 8 c and Figure 8As shown in k, sufficient space can be reserved for the lower clamping assembly 6 to clamp the bottle bodies of the upper row of bottle bodies 20 and the bottle heads of the lower row of bottle bodies 20 at the same time. In step S3, the lower clamping assembly 6 is opened while the bottle body mold 5 forms the bottle body to prepare for the next clamping. Of course, in other embodiments, it can also be opened during the descending process of step S4; in step S5, the lower clamping assembly 6 rises to the initial position. In step S6, the moving distance of the lower clamping assembly 6 is zero, which is conducive to simplifying the movement process of the lower clamping assembly 6 and improving production efficiency.

[0057] Furthermore, in this embodiment,

[0058] In step S4, after the bottle head mold 4 is molded to form the bottle head, the upper clamping assembly 7 clamps the embryo 10, as shown in the following example. Figure 8 As shown in FIG. 5 , the second lifting mechanism 9 then drives the bottle head mold 4, the bottle body mold 5 and the upper clamping assembly 7 to synchronously descend to the set position along with the embryo 10;

[0059] In step S5, after the bottle head mold 4 is opened, the upper clamping assembly 7 is opened. Figure 8 i and Figure 8 As shown in j;

[0060] In step S6, the second lifting mechanism 9 drives the bottle head mold 4, the bottle body mold 5 and the upper clamping assembly 7 to rise to the initial position, as shown in the following figure. Figure 8 k shown.
