Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging equipment, in particular to a bottle clamping mechanism of a blow-fill-seal integrated machine and the blow-fill-seal integrated machine. Background Art

[0002] Chinese patent document CN114835078A discloses a continuous production blow-fill-seal device and its use method, which can continuously complete the extrusion, molding, filling and sealing processes, which is conducive to improving production efficiency. The embryo is in a closed state throughout the production process, avoiding the risk of contamination of the filling liquid by the external environment. Among them, the lower clamping assembly includes a pair of clamping plates, the inner side of which is provided with a bottle body positioning groove, and the bottle head positioning groove is provided below the bottle body positioning groove. The sides of the bottle body positioning groove and the bottle head positioning groove are provided with cooling channels. After the bottle body mold is opened, the lower clamping assembly can be driven by a first lifting mechanism to rise between the bottle body molds, clamping and fixing the bottle body of the upper bottle and the bottle head of the lower bottle, effectively preventing the embryo from shaking when the bottle head mold and the bottle body mold are opened and closed. In addition, the coolant flowing into the cooling channel in the clamping plate can cool the formed bottle body, which is conducive to ensuring the consistency of the bottle body. However, in this technical solution, the bottle body positioning groove and the bottle head positioning groove are directly arranged on the inner side of the splint. When the bottle specifications produced by the blow-fill-seal equipment (for example, 0.8ml, 2.5ml and 5ml bottles) change, the splint needs to be replaced as a whole. The processing and replacement and debugging of the splints take a long time, which reduces production efficiency. In addition, preparing multiple sets of splints of different specifications will also increase production costs. Utility Model Content

[0031] Example 1

[0032] Figures 1 to 6 An embodiment of the bottle clamping mechanism of the blow-fill-seal machine of the utility model is shown. The bottle clamping mechanism of the blow-fill-seal machine of this embodiment includes relatively arranged mounting plates 1, an insert 2 is provided on the inner side of the mounting plate 1, the mounting plate 1 and the insert 2 are detachably connected, at least a part of the bottle body cavity is provided on the insert 2, and the insert 2 and the mounting plate 1 together constitute the bottle body cavity.

[0033] The bottle clamping mechanism of the blow-fill-seal machine of this embodiment is provided with a detachable insert 2 on the inner side of the mounting plate 1, and the insert 2 is provided with a partial bottle body cavity. When the bottle body specifications change, the insert 2 can be removed and replaced with an insert 2 of the corresponding specifications. The mounting plate 1 does not need to be disassembled, replaced or adjusted, which is conducive to shortening the time required for specification adjustment. Since different inserts 2 share the mounting plate 1, it can also reduce production costs. Figure 1 、 Figure 3 and Figure 5 In this embodiment, the specifications of the bottle body 9 are increased, which is mainly reflected in the increase in the length of the bottle body, while the shapes of the bottle head and the upper part of the bottle body remain unchanged. Therefore, the upper part of the bottle body cavity can be set on the mounting plate 1, and the lower part of the bottle body cavity can be set on the insert 2. As the specifications of the bottle body 9 gradually increase, the proportion of the bottle body cavity located on the insert 2 also gradually increases, and the corresponding insert 2 can be replaced.

[0034] As a preferred embodiment, the insert 2 is provided with a body cavity and a tail cavity. The tail cavity can form a continuous plastic bottle sheet. The tail is the connecting portion between the body of the bottle 9 in the previous row and the bottle head of the bottle 9 in the next row.

[0035] As a preferred embodiment, the bottle tail cavity is located below the bottle body cavity.

[0036] As a preferred embodiment, a bottle head cavity is provided on the mounting plate 1. The bottle head cavity cooperates with the bottle body cavity to completely clamp the bottle body 9.

[0037] As a preferred embodiment, the mounting plate 1 is provided with two inserts 2 in the vertical direction. The two inserts 2 mounted on the mounting plate 1 are of the same specifications and can be interchanged, further enhancing versatility. Of course, in other embodiments, the number of inserts 2 can also be further adjusted.

[0038] Furthermore, in this embodiment, a cooling channel 3 is provided in the mounting plate 1. During operation, a coolant (such as cooling water) is passed through the cooling channel 3 to perform secondary cooling on the bottle body 9, thereby improving the molding quality of the bottle body 9 and preventing the mounting plate 1 and the insert 2 from overheating.

[0039] In a preferred embodiment, the mounting plate 1 and the insert 2 are connected via threaded fasteners 4 (bolts, screws, etc.). This threaded fastener 4 provides a removable connection between the mounting plate 1 and the insert 2, offering high reliability and ease of assembly and disassembly. In other embodiments, the removable connection between the mounting plate 1 and the insert 2 can also be achieved using a snap-fit ​​mechanism or other similar means.
