Description

A bottle clamping mechanism for a blow-fill-seal integrated machine and the blow-fill-seal integrated machine itself.

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202422706133.2, filed on November 6, 2024, entitled "A Bottle Clamping Mechanism and a Blow-Fill-Seal Integrated Machine", the full text of which is incorporated herein by reference as a part of this application. Technical Field

[0003] This invention relates to the field of food and pharmaceutical packaging equipment technology, and in particular to a bottle clamping mechanism and a blow-fill-seal integrated machine. Background Technology

[0004] Chinese patent document CN114835078A discloses a continuous blow-fill-seal equipment and its usage method, which can continuously complete the extrusion, molding, filling, and sealing processes, thereby improving production efficiency. Throughout the entire production process, the preform remains in a closed state, avoiding the risk of contamination of the filled liquid by the external environment. The lower clamping assembly includes a pair of clamping plates. The inner side of the clamping plates has a bottle body positioning groove, and below the bottle body positioning groove is a bottle head positioning groove. Cooling channels are provided on the sides of the bottle body positioning groove and the bottle head positioning groove. After the bottle body mold opens, the lower clamping assembly, driven by a first lifting mechanism, can rise between the bottle body molds, simultaneously clamping and fixing the bottle body above and the bottle head below. This effectively prevents the preform from shaking when the bottle head mold and bottle body mold open and close. Furthermore, the coolant flowing through the cooling channels inside the clamping plates cools the molded bottle, helping to ensure the consistency of the bottle. However, in this technical solution, the bottle body positioning groove and the bottle head positioning groove are directly located inside the clamp. When the bottle specifications produced by the blow-fill-seal equipment (e.g., 0.8ml, 2.5ml and 5ml bottles) change, the entire clamp needs to be replaced. The clamp processing and replacement debugging takes a long time, which reduces production efficiency. In addition, preparing multiple sets of clamps of different specifications will also increase production costs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a bottle clamping mechanism for a blow-fill-seal integrated machine that is simple in structure, easy to adjust in size, and conducive to reducing costs.

[0006] The present invention further provides a blow-fill-seal integrated machine including the above-mentioned bottle clamping mechanism.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A bottle clamping mechanism for a blow-fill-seal integrated machine includes mounting plates arranged opposite each other. An insert is provided on the inner side of the mounting plate. The mounting plate and the insert are detachably connected. At least a portion of the bottle body cavity is provided on the insert. The insert and the mounting plate together constitute the bottle body cavity.

[0009] In some embodiments of the present invention: the insert is provided with a bottle body cavity and a bottle tail cavity.

[0010] In some embodiments of the present invention: the bottle tail cavity is located below the bottle body cavity.

[0011] In some embodiments of the present invention: the mounting plate is provided with a bottle head cavity.

[0012] In some embodiments of the present invention, the mounting plate is provided with two or more inserts along the vertical direction.

[0013] In some embodiments of the present invention, the mounting plate is further provided with a cooling channel.

[0014] In some embodiments of the present invention, the mounting plate and the insert are connected by threaded fasteners.

[0015] A blow-fill-seal integrated machine includes an extrusion die, a filling needle inserted into the extrusion die, a bottle head mold located below the extrusion die, and a bottle body mold located below the bottle head mold. The bottle head mold is further provided with a bottle clamping mechanism for the blow-fill-seal integrated machine.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] The bottle clamping mechanism of the blow-fill-seal integrated machine disclosed in this invention has a detachable insert on the inner side of the mounting plate, and the insert has a partial bottle body cavity. When the bottle size changes, the insert can be removed and replaced with an insert of the corresponding size. The mounting plate does not need to be disassembled, replaced and adjusted, which helps to shorten the time required for size adjustment. Since different inserts share the mounting plate, production costs can also be reduced.

[0018] The blow-fill-seal integrated machine disclosed in this invention includes the bottle clamping mechanism of the blow-fill-seal integrated machine described above, and therefore also has the above-mentioned advantages.

[0019] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0033] Figures 1 to 6 show an embodiment of the bottle clamping mechanism of the blow-fill-seal integrated machine of the present invention. The bottle clamping mechanism of the blow-fill-seal integrated machine of this embodiment includes a mounting plate 1 arranged opposite to each other. 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. The insert 2 is provided with at least a portion of the bottle body cavity. The insert 2 and the mounting plate 1 together constitute the bottle body cavity.

[0034] The bottle clamping mechanism of the blow-fill-seal integrated machine in this embodiment has a detachable insert 2 on the inner side of the mounting plate 1, and the insert 2 has a portion of the bottle body cavity. When the bottle size changes, the insert 2 can be removed and replaced with an insert 2 of the corresponding size. The mounting plate 1 does not need to be disassembled, replaced, or adjusted, which helps to shorten the time required for size adjustment. Since different inserts 2 share the mounting plate 1, production costs can also be reduced. See Figures 1, 3, and 5 for details. In this embodiment, the bottle size 9 is increased, mainly in terms of the increase in bottle length. 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 bottle size 9 gradually increases, the proportion of the bottle body cavity located on the insert 2 also gradually increases. The corresponding insert 2 can be replaced.

[0035] In a preferred embodiment, the insert 2 is provided with a bottle body cavity and a bottle tail cavity. The bottle tail cavity allows for the formation of continuous plastic bottle sheets. The bottle tail refers to the connection between the bottle body of one row of bottles 9 and the bottle head of the next row of bottles 9.

[0036] In a preferred embodiment, the bottle tail cavity is located below the bottle body cavity.

[0037] In a preferred embodiment, the mounting plate 1 is provided with a bottle head cavity. The bottle head cavity, in conjunction with the bottle body cavity, can completely clamp the bottle body 9.

[0038] In a preferred embodiment, the mounting plate 1 has two inserts 2 along the vertical direction. The two inserts 2 mounted on the mounting plate 1 are of the same specification and can be interchanged, further improving versatility. Of course, in other embodiments, the number of inserts 2 can be further adjusted.

[0039] Furthermore, in this embodiment, the mounting plate 1 is also provided with a cooling channel 3. During operation, coolant (such as cooling water) is introduced into the cooling channel 3, which can perform secondary cooling on the bottle body 9, which is beneficial to improving the molding quality of the bottle body 9, and can also prevent the mounting plate 1 and the insert 2 from overheating.

[0040] In a preferred embodiment, the mounting plate 1 and the insert 2 are connected by threaded fasteners 4 (bolts, screws, etc.). The threaded fasteners 4 provide a detachable connection between the mounting plate 1 and the insert 2, offering good reliability and ease of assembly and disassembly. Of course, in other embodiments, a detachable connection between the mounting plate 1 and the insert 2 can also be achieved through snap-fit ​​mechanisms or similar methods. Example 2

[0041] Figures 7 and 8 show an embodiment of the blow-fill-seal integrated machine of the present invention. The blow-fill-seal integrated machine of this embodiment includes an extrusion die 5, a filling needle 6 passing through the extrusion die 5, a bottle head mold 7 located below the extrusion die 5, and a bottle body mold 8 located below the bottle head mold 7. The bottle head mold 7 is also provided with the bottle clamping mechanism of the blow-fill-seal integrated machine.

[0042] The blow-fill-seal integrated machine of this embodiment includes the bottle clamping mechanism of the blow-fill-seal integrated machine described above, and therefore also has the above-mentioned advantages.

[0043] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
