Abstract

This invention discloses a continuous blow-fill-seal device, including a forming mold. The forming mold has a first bottle forming area, a second bottle forming area, and a waste forming area. The waste forming area is located between the first and second bottle forming areas and on both sides of the first and second bottle forming areas. The waste forming area has a forming protrusion for forming a positioning recess in the waste area of ​​the sheet metal. The forming mold of this invention has a forming protrusion in the waste forming area for forming a positioning recess in the waste area of ​​the sheet metal. The positioning recess can separate the waste area, which helps prevent the waste area of ​​the sheet metal from collapsing, reduces sheet metal deformation, and thus shortens the sheet metal cooling time. Furthermore, it can be used for positioning during subsequent punching, helping to improve the accuracy of sheet metal positioning.

Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging equipment technology, and in particular to a continuous blow-fill-seal equipment. Background Technology

[0002] like Figure 1 and Figure 2 As shown in (a), ideally, the scrap area of ​​the sheet metal should be hollow. If the scrap area collapses, it can easily lead to a prolonged cooling time for the sheet metal, affecting production efficiency. Furthermore, the sheet metal is prone to deformation, making it difficult to twist off the bottle. During subsequent punching, the scrap and bottle are also difficult to separate. Moreover, due to continuous production, the lengths of the bottles in each row on the sheet metal will change to varying degrees after deformation, resulting in defective products and preventing the equipment from operating continuously and stably. However, if... Figure 2 As shown in (b), during actual production, the temperature of the tube blank in the molten state is relatively high, and the dimensions of the scrap area in both the length and width directions are relatively large. This inevitably leads to a large area of ​​collapse in the scrap area, and a large area of ​​bulges will form outside the collapsed area. This is quite different from the ideal situation. The larger the area of ​​the scrap area, the more serious this situation becomes. Furthermore, during subsequent punching, the positioning mold is easily affected by the thickness of the scrap area of ​​the sheet metal, resulting in misalignment and inaccurate positioning. During punching, the bottle body is easily squeezed and deformed. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a continuous blow-fill-seal device with a simple structure that helps to reduce sheet deformation, shorten sheet cooling time, and improve positioning accuracy.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A continuous blow-fill-seal device includes a molding die, which has a first bottle forming area, a second bottle forming area, and a waste forming area. The waste forming area is located between the first bottle forming area and the second bottle forming area, and on both sides of the first bottle forming area and the second bottle forming area. The waste forming area has a forming protrusion for forming a positioning recess in the waste area of ​​the sheet material.

[0006] As a further improvement to the above technical solution: the positioning recesses on the two sides of the waste area are connected as one unit.

[0007] As a further improvement to the above technical solution: the shaped protrusion includes a shaped protrusion strip.

[0008] As a further improvement to the above technical solution: the forming convex strip is arranged horizontally or vertically.

[0009] As a further improvement to the above technical solution: the forming convex strip is provided in multiple parallel arrangement.

[0010] As a further improvement to the above technical solution: the shaped protrusion includes a plurality of conical shaped protrusions.

[0011] As a further improvement to the above technical solution: the continuous blow-fill-seal equipment also includes a punching and positioning die, wherein the punching and positioning die is provided with a first positioning protrusion that cooperates with the positioning recess.

[0012] As a further improvement to the above technical solution: the first positioning protrusion includes a positioning protrusion strip.

[0013] As a further improvement to the above technical solution, the blanking positioning die is also provided with a plurality of second positioning protrusions.

[0014] As a further improvement to the above technical solution: the second positioning protrusion is a conical positioning protrusion.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The continuous blow-fill-seal equipment disclosed in the present invention has a forming protrusion in the waste forming area of ​​the forming mold, which is used to form a positioning recess in the waste area of ​​the sheet material. The positioning recess can divide the waste area, which helps to prevent the waste area of ​​the sheet material from collapsing, reduce the deformation of the sheet material, and thus help to shorten the cooling time of the sheet material. In addition, it can be used for positioning during subsequent punching, which helps to improve the accuracy of sheet material positioning. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] Figures 3 to 7An embodiment of the continuous blow-fill-seal device of the present invention is shown. The continuous blow-fill-seal device of this embodiment includes a molding die 1. The molding die 1 is provided with a first bottle forming area 11, a second bottle forming area 12 and a waste forming area 13. The waste forming area 13 located between the first bottle forming area 11 and the second bottle forming area 12 is provided with a forming protrusion 14 for forming a positioning recess 32 in the waste area 31 of the sheet material 3.

[0033] In this embodiment of the continuous blow-fill-seal equipment, the forming mold 1 has a forming protrusion 14 in the waste forming area 13, which is used to form a positioning recess 32 in the waste area 31 of the sheet material 3. The positioning recess 32 can divide the waste area 31, which helps to prevent the waste area 31 of the sheet material 3 from collapsing, reduces the deformation of the sheet material 3, and thus helps to ensure the length of each row of bottles 30 on the sheet material 3. The equipment can operate stably, shorten the cooling time of the sheet material 3, and can be used for positioning during subsequent punching, which helps to improve the positioning accuracy of the sheet material 3. Compared with forming the positioning recess 32 in the waste area 31, forming the protrusion in the waste area 31, although it can also be used for positioning and improve the positioning accuracy of the sheet material 3, the protrusion is similar to the bottle 30 (the bottle 30 is a protruding structure formed by tube blank), has poor stability, and cannot prevent the waste area 31 of the sheet material 3 from collapsing.

[0034] Furthermore, in this embodiment, the positioning recesses 32 on the two surfaces of the waste area 31 are connected as one unit (see details). Figure 3 and Figure 5 Preferably, the forming mold 1 vertically forms multiple positioning recesses 32 on the left and right sides of the waste area 31 (the positioning recesses 32 on the left and right sides of the waste area 31 are connected one-to-one), or in other words, the positions corresponding to the positioning recesses 32 in the waste area 31 are solid structures. The continuous blow-fill-seal equipment also includes a punching positioning mold 2, which has a first positioning protrusion 21 that cooperates with the positioning recesses 32. Since each positioning recess 32 on the two sides of the waste area 31 is a solid structure, it can reliably separate the waste area 31, while having good stability and high strength, effectively preventing the waste area 31 of the sheet 3 from collapsing and reducing the deformation of the sheet 3. When the sheet 3 needs to be punched, the first positioning protrusion 21 is pressed against the positioning recess 32 without any play, making the positioning more accurate. Furthermore, the thickness of the position corresponding to the positioning recess 32 is very thin, unaffected by the thickness change of the waste area 31, avoiding the bottle body 30 being squeezed and deformed during punching. Preferably, a sheet material conveying mechanism 4 (e.g., a conveyor belt) is provided between the forming mold 1 and the blanking positioning mold 2 to realize the automatic transfer of the sheet material 3 between the forming mold 1 and the blanking positioning mold 2. The structure is simple and effective.

[0035] Furthermore, in this embodiment, the forming protrusion 14 includes a forming rib. The forming rib can form a strip-shaped positioning groove in the waste area 31. The positioning groove can act as a reinforcing rib, effectively preventing the waste area 31 of the sheet 3 from collapsing, reducing the deformation of the sheet 3, shortening the cooling time of the sheet 3, and also facilitating reliable positioning of the sheet 3 by cooperating with the first positioning protrusion 21.

[0036] See details Figure 4 and Figure 6 As a preferred embodiment, the forming protrusions are arranged horizontally (i.e., in the width direction of the waste forming area 13, which is the left-right direction in the figure) or vertically (i.e., in the height direction of the waste forming area 13, which is the up-down direction in the figure), resulting in a simple and effective structure. Of course, in other embodiments, the forming protrusions can also be oblique or curved structures, which will not be elaborated further.

[0037] Furthermore, in this embodiment, multiple forming protrusions are provided and arranged in parallel, which helps to ensure that the waste area 31 obtained by forming remains uniform throughout.

[0038] Of course, in other embodiments, the forming protrusion 14 may also include multiple conical forming protrusions. Multiple conical forming protrusions can form multiple conical recesses in the scrap area 31, and can also prevent the scrap area 31 of the sheet 3 from collapsing, reduce the deformation of the sheet 3, and shorten the cooling time of the sheet 3, etc. However, compared with forming protrusions, the structure is more complex.

[0039] Furthermore, in this embodiment, the first positioning protrusion 21 includes a positioning ridge. The positioning ridge cooperates with the strip-shaped positioning groove to provide good positioning and prevent the position of the sheet metal 3 from shifting. Preferably, the length of the positioning ridge is shorter than that of the forming ridge to ensure that the positioning ridge can be fully pressed into the positioning groove.

[0040] Furthermore, in this embodiment, the blanking positioning die 2 is also provided with a plurality of second positioning protrusions 22. The second positioning protrusions 22 can be used to press the area of ​​the sheet metal 3 other than the scrap area 31, thereby cooperating with the first positioning protrusions 21 to complete the accurate positioning of the sheet metal 3 as a whole.

[0041] In a preferred embodiment, the second positioning protrusion 22 is a conical positioning protrusion. Preferably, the punching positioning die 2 includes an upper positioning die 23 and a lower positioning die 24. Both the upper positioning die 23 and the lower positioning die 24 are provided with first positioning protrusions 21, which respectively cooperate with the positioning recesses 32 on the upper and lower sides of the scrap area 31. The second positioning protrusion 22 is only provided on the upper positioning die 23, which can complete the reliable positioning of the entire sheet metal 3.

[0044] In this embodiment, the waste forming area 13 between the first bottle forming area 11 and the second bottle forming area 12 has a small area. The waste forming area 13 located on both sides of the first bottle forming area 11 and the second bottle forming area 12 is provided with a forming protrusion 14 for forming a positioning recess 32 in the waste area 31 of the sheet material 3.

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.
