Description

Technical Field

[0001] The utility model relates to the field of food and medicine packaging machinery, in particular to a mold structure of a continuous blowing, filling and sealing integrated machine and the continuous blowing, filling and sealing integrated machine. Background Art

[0002] For a single-mode continuous blowing, filling and sealing machine, the molten plastic tube embryo extruded by the extrusion die head is continuously extruded without being cut off, and is transported downward to a set of molding molds that can move up and down. The molding mold includes a main mold and a head mold, which are opened and closed in the center on the left and right. The plastic tube embryo extrusion speed is kept consistent with the downward speed of the mold to complete the molding, filling and sealing of the plastic ampoule. All these processes are completed at one time under sterile conditions, and the entire cycle is generally within 7-10 seconds.

[0003] The main mold is closed to form the bottle body, and then the filling needle is lowered to fill the liquid medicine, and finally the filling needle is raised to reset. This process takes a long time, which makes the main mold cooling time longer and the plastic ampoule is fully cooled. The head mold is closed to seal the plastic ampoule, and this process takes a short time, which makes the head mold cooling time short and the cooling effect on the plastic ampoule is poor. If the cooling time of the head mold is directly extended to achieve a better cooling effect, it will cause the entire molding cycle to become longer and the production capacity to become lower.

[0004] like Figure 1 and Figure 2 As shown, there are two ways to form plastic ampoules, namely, forward filling and reverse filling. In forward filling, the handle is formed in the head mold, and in reverse filling, the labeling area is formed in the head mold. The labeling area and the handle have a small stretch ratio during the molding process, a large thickness, and a slow cooling speed. If the handle or labeling area of ​​the plastic ampoule is formed in the head mold, the cooling effect is poor due to the short cooling time, which will cause bulging, resulting in defects such as unstable subsequent labeling and poor bottle appearance. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a mold structure of a continuous blowing, filling and sealing integrated machine which has a simple structure, is conducive to improving the cooling effect and avoids prolonging the molding cycle.

[0006] The utility model further provides a continuous blowing, filling and sealing integrated machine comprising the mold structure of the continuous blowing, filling and sealing integrated machine.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] As a further improvement of the above technical solution: the main mold is equipped with a mold opening and closing driving component, and the cooling component is arranged on the mold opening and closing driving component.

[0010] As a further improvement of the above technical solution: when the main mold is closed, there is a gap between the cooling parts on both sides.

[0034] Embodiment 1

[0035] Figures 2 to 8 An embodiment of the mold structure of the continuous blowing, filling and sealing machine of the utility model is shown. The mold structure of the continuous blowing, filling and sealing machine of this embodiment includes a main mold 1 for forming a bottle body 101 and a head mold 2 for sealing the bottle body 101. Cooling channels 3 (such as water cooling channels, etc.) are provided in the main mold 1 and the head mold 2. A cooling member 4 that can move along the closing direction of the main mold 1 is provided below the main mold 1, and a cooling channel 3 is also provided in the cooling member 4.

[0036] The mold structure of the continuous blowing, filling and sealing machine of this embodiment is provided with a cooling member 4 movable along the mold closing direction of the main mold 1 below the main mold 1, and a cooling channel 3 is also provided in the cooling member 4. Figure 7 and Figure 8 As shown, when the main mold 1 is molding the bottle body 101 of the second row of bottles, the cooling member 4 does not participate in the molding, but can cool the portion of the first row of bottles that is molded by the head mold 2 (in this embodiment, it is reverse pouring molding, so the head mold 2 molds a labeling area 103. Of course, in other embodiments, if it is forward pouring molding, the head mold 2 molds a handle portion 102) again, and can continue until the sealing clamp 5 completes the sealing, thereby improving the cooling effect, avoiding defects such as bulging caused by poor cooling effect, unstable subsequent labeling, and poor bottle appearance, and compared with directly extending the cooling time of the head mold, it avoids lengthening the molding cycle, and the structure is simple and effective.

[0037] Furthermore, in this embodiment, the main mold 1 is equipped with a mold opening and closing driving member 11 (for example, a cylinder, a screw nut pair, etc.), and the cooling member 4 is arranged on the mold opening and closing driving member 11. The cooling member 4 and the main mold 1 share a common drive, which can ensure that the two operate synchronously, while reducing the number of driving components, simplifying the structure, and reducing costs. Of course, in other embodiments, the cooling member 4 can also be equipped with a separate driving member, but it will lead to a complex structure and increased costs.

[0038] Furthermore, in this embodiment, when the main mold 1 is closed, there is a gap between the cooling members 4 on both sides. Figure 4 and Figure 5 The gap between the cooling members 4 on both sides can accommodate the labeling area 103 of the upper row of bottles formed by the head mold 2. When the labeling area 103 is cooled, it only contacts the labeling area 103 without causing extrusion deformation. The structure is reasonable and effective.

[0039] As a preferred embodiment, the cooling element 4 is made of aluminum. The cooling element 4 made of aluminum is light in weight and has good heat conduction effect, which is conducive to further improving the secondary cooling effect.

[0040] Of course, in other embodiments, the cooling member 4 may also be made of copper. The cooling member 4 made of copper also has a good thermal conductivity, but its cost is higher than that of aluminum.

[0041] Furthermore, in this embodiment, a sealing clamp 5 is provided above the head mold 2. Figure 5 and Figure 8 After the sealing clips 5 are closed and sealed, a partition can be formed between two adjacent rows of bottles, which is convenient for subsequent cutting and other processes.

[0042] Embodiment 2

[0043] Figures 2 to 8 An embodiment of the continuous blowing, filling and sealing machine of the utility model is shown. The continuous blowing, filling and sealing machine of this embodiment includes an extrusion die head 6 and a filling needle 7 inserted into the extrusion die head 6. The mold structure of the continuous blowing, filling and sealing machine is arranged below the extrusion die head 6.

[0044] The continuous blowing, filling and sealing machine of this embodiment includes the mold structure of the continuous blowing, filling and sealing machine described above, and thus also has the above advantages.

[0045] The working process of the continuous blowing, filling and sealing machine of this embodiment is as follows:

[0046] See also Figure 3 , the extrusion die head 6 continuously extrude the rubber blank;

[0047] See also Figure 4 Driven by the mold opening and closing driving member 11, the main mold 1 is closed, and the cooling members 4 on both sides are moved closer to each other and simultaneously descend with the rubber blank. The main mold 1 is closed to form the bottle body 101, and the filling needle 7 descends to fill the liquid medicine into the bottle body 101, and then rises to reset;

[0048] See also Figure 5 The head mold 2 closes the mold to seal the bottle body 101 and form the labeling area 103, and the sealing clamp 5 seals it. At the same time, the head mold 2 and the sealing clamp 5 descend synchronously with the rubber blank to complete the first molding cycle;

[0049] See also Figure 6 , the main mold 1, head mold 2, etc. are opened and raised to reset, ready for the next molding cycle;

[0050] See also Figure 7 Driven by the mold opening and closing driving member 11, the main mold 1 is closed again, and the cooling members 4 on both sides are brought closer to each other again. At this time, the cooling members 4 can perform secondary cooling on the labeling area 103 of the bottle body formed in the first molding cycle, see Figure 8 The secondary cooling process of the cooling member 4 can continue until the main mold 1 and the head mold 2 are opened again.

[0051] Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
