Description

Technical Field

[0001] The utility model relates to the technical field of straw packaging, in particular to a straw packaging film and an indentation device thereof. Background Art

[0002] These medicinal straws are made from 100% pure PP, a non-toxic, hygienic, heat-resistant, and recyclable material. They are rust-resistant, wear-resistant, scale-resistant, and freeze-crack-resistant, making them hygienic, safe, and convenient to use. They feature five to twelve ridges evenly distributed across their surface, with eight being preferred. The straws have a pointed end at one end and a flat end at the other. These ridges intersect perpendicularly with the flat ends, making the pointed ends easier to penetrate the container seal and facilitate liquid aspiration. Existing medicinal straws, when packaged in single rows, use a heated protective film on the outer edges perpendicular to the straws, heat-sealing each straw into a roll. The rolled straws are then unwound and cut parallel to the straws into custom-sized units. When removing one or more straws, tearing the heat-sealed edges of the straw units can cause irregular breaks, potentially causing unwanted straws to fall or become exposed to air and contaminate them.

It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0028] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

[0029] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0030] The present invention will now be further described with reference to the accompanying drawings.

[0031] When existing straw packaging films are used to package multiple straws in a row, each straw is enclosed in an independent space, and the independent spaces are not connected. During use, one or more straws are taken out for use by tearing open the heat-sealed edges between the independent spaces, which are arranged parallel to the length direction of the straws. This method can easily lead to irregular path breakage when tearing open the heat-sealed edges, which may cause other unnecessary straws to fall or be exposed to the air and cause contamination.

[0032] Based on this, embodiments of the present invention provide a straw packaging film and a creasing device therefor. Compared to existing straw packaging films, the straw packaging film is easier to tear and remove, ensuring that it breaks along a predetermined path during tearing, preventing it from running off the edge or being easily torn to other locations. This ensures that the straws do not leak air and are not contaminated by the environment. The creasing device is used to create indentations (i.e., dotted lines) in the straw packaging film.

[0033] First, the embodiment of the present invention provides a straw packaging film, such as Figure 1 As shown, the straw packaging film includes a film 1, and a plurality of independent and sealed cavities 101 are arranged inside the film 1. The cavity 101 is used to place the straw 2. The cavity 101 has a first port 1011 and a second port 1012 relative to each other. The plurality of cavities 101 are evenly arranged, and the first port 1011 and the second port 1012 of each cavity 101 are flush. A dotted line 102 is provided on the film 1, and the line segment formed by the dotted line 102 and the first port 1011 of each cavity 101 is flush.

[0034] In this embodiment, the cavity 101 is sealed, and the dotted line 102 refers to a line segment formed by multiple through holes on the film 1. The dotted line 102 is close to the first port 1011 of the cavity 101. It should be noted that the first port 1011 and the second port 1012 of each cavity 101 are both closed ports. The dotted line 102 is 0.1 to 1.5 mm away from the first port 1011 of the cavity 101, ensuring that the first port 1011 is still sealed when the dotted line 102 is torn. When taking out the straw 2 in the cavity 101, if you need to take out a straw, tear the dotted line 102 to the first port 1011 of the cavity 101 where the corresponding straw is located, and then use the straw to pierce the first port 1011 to take out the straw 2. This can prevent other unnecessary straws from falling or being exposed to the air and causing contamination. At the same time, the use of the dotted line 102 can ensure that the tearing is carried out along the set path. This is because the dotted line is formed by multiple through holes, and the lengths on both sides of each through hole are relatively short. When tearing, it will only be gradually torn in the direction of the layout of the through holes, so the path is regular.

[0035] In some embodiments, as Figure 2 As shown, a plurality of cavities 101 are arranged in an array to form two cavity groups 103 arranged side by side in the film 1, namely an upper cavity group 1031 and a lower cavity group 1032, wherein the first port 1011 and the second port 1012 of each cavity 101 in the upper cavity group 1031 are all flush, and the first port 1011 and the second port 1012 of each cavity 101 in the lower cavity group 1032 are all flush, and a dividing point break line 104 is provided on the film 1 between the upper cavity group 1031 and the lower cavity group 1032, and the point break line 102 is provided with two, namely a first point break line 1021 and a second point break line 1022, the first point break line 1021 is located at the upper end of the first port 1011 of each cavity 101 in the upper cavity group 1031, and the second point break line 1022 is located at the upper end of the first port 1011 of each cavity 101 in the lower cavity group 1032.

[0036] In this embodiment, the straw packaging film is designed to have two rows of arrangements, namely, two parallel rows of upper cavity groups 1031 and lower cavity groups 1032. The method of taking out the straws 2 from each cavity 101 in the upper cavity group 1031 and the lower cavity group 1032 has been described above and will not be repeated here. The dividing point break line 104 can serve as the folding line of the straw packaging film. When not in use, it can be folded through the dividing point break line 104. At the same time, the dividing point break line 104 can also serve as the tearing line of the straw packaging film. After the dividing point break line 104 is torn, the straw packaging film will be divided into two independent rows of straw packaging films. Its specific structure is as follows: Figure 1 The structure shown.

[0037] Secondly, the embodiment of the present invention also provides a straw packaging film indentation device, such as Figure 3 As shown, the indentation device includes a straw unwinding shaft 3, a straw upper pressing shaft 4, an indentation driven shaft 5 and a dot-break line rolling cutter assembly 6. The straw unwinding shaft 3 is used to unwind the straw packaging film 7 equipped with straws between the straw upper pressing shaft 4 and the indentation driven shaft 5. The straw upper pressing shaft 4 is connected to a power assembly (not shown in the figure). Under the action of the power assembly, the straw upper pressing shaft 4 drives the straw packaging film 7 equipped with straws to move on the indentation driven shaft 5. The dot-break line rolling cutter assembly 6 is arranged on one side of the indentation driven shaft 5. When the straw packaging film 7 equipped with straws moves on the indentation driven shaft 5, the dot-break line rolling cutter assembly 6 forms dot-break lines on the straw packaging film 7 equipped with straws.

[0038] In this embodiment, the indentation device of the straw packaging film is particularly suitable for Figure 1 or Figure 2 The straw packaging film is shown as being indented. When packaging individual medicinal straws in a row, heated packaging film is applied to the outer edges perpendicular to the straws, sealing each straw individually before being rolled up (this is a common straw packaging process and will not be described in detail in this embodiment). The wound straws are then unwound and rolled using the straw packaging film indentation device, followed by a dotted-line indentation of the sealed edges by the unwinding mechanism and the dotted-line rolling cutter assembly 6.

[0039] Specifically, the straw unwinding shaft 3 unwinds the straw packaging film 7 containing the straws between the straw pressing shaft 4 and the indentation driven shaft 5. The power assembly connected to the straw pressing shaft 4 can be a motor or other existing device capable of driving the straw pressing shaft 4 to rotate. Under the action of the straw pressing shaft 4, the straw packaging film 7 containing the straws moves on the indentation driven shaft 5. Simultaneously, the dot-break line rolling cutter assembly 6 contacts the straw packaging film 7 containing the straws, forming dot-break lines on the straw packaging film 7 through the dot-break line rolling cutter assembly 6. In this embodiment, during the indentation process, the dot-break line rolling cutter assembly 6 performs a passive rolling indentation. Its power is derived from the power of the straw pressing shaft 4, requiring no additional power. This allows it to synchronize with the speed of the straw pressing shaft 4, ensuring a uniform indentation line and facilitating the tearing of the formed dot-break lines. Furthermore, the entire process can be automated to ensure that the breakpoints on each straw packaging film meet design requirements.

[0040] In some embodiments, as Figure 4 As shown, the dotted line rolling cutter assembly 6 includes at least one dotted line rolling cutter 601, a cylinder 602, a cutter mounting plate 603 and a linear bearing slider 604. The cutter mounting plate 602 is arranged on the linear bearing slider 604, the telescopic end of the cylinder 602 is connected to the cutter mounting plate 603, and the dotted line rolling cutter 601 is rotatably arranged on the cutter mounting plate 603.

[0041] In this embodiment, the indentation force is adjusted by adjusting the components of the dot-break line rolling cutter assembly 6 according to the material of the straw packaging product. Specifically, the cutter mounting plate 602, driven by a pneumatic cylinder 602, moves horizontally along a linear bearing slider 604, allowing the dot-break line rolling cutter 601 to move closer to or further from the straw packaging film 7 containing the straws. If the dot-break line rolling cutter 601 moves closer to the straw packaging film 7, the indentation force is increased; if the dot-break line rolling cutter 601 moves closer to the straw packaging film 7, the indentation force is decreased, thus achieving adjustable indentation force.

[0042] Exemplarily, the dot-break line rolling cutter 601 may be a circular cutter having a plurality of cutting edges 6011 thereon. When the cutting edges 6011 come into contact with the straw packaging film 7 containing the straws, the film is cut to form through holes. The plurality of cutting edges 6011 respectively come into contact with the straw packaging film 7 containing the straws to form a plurality of evenly distributed through holes on the straw packaging film 7 containing the straws, thereby forming a dot-break line that can be torn along a set path.

[0043] In some embodiments, the cutter 601 is provided in a manner that is rotatably mounted on the cutter mounting plate 603, such as Figure 5 and Figure 6 As shown, at least one rolling cutter mounting seat 605 is provided on the cutter mounting plate 603, and the dotted line rolling cutter 601 is installed on the rolling cutter mounting seat 605. A cutter shaft 606 is provided on the rolling cutter mounting seat 605, and the dotted line rolling cutter 601 is set on the cutter shaft 606.

[0044] In some embodiments, as Figure 4 As shown, the broken line rolling cutter 601 is set to three. When the broken line rolling cutter 601 is set, the following can be processed: Figure 2 The structure of the straw packaging film is shown.

[0045] Certainly, when three point broken line rolling cutters 601 are set, also can be processed as follows Figure 1 Specifically, the middle one of the three dot-break line rolling cutters 601 is selected as a cutting cutter, which directly cuts the middle of the straw packaging film 7 containing the straw, thereby obtaining two pieces of the straw packaging film in one processing. Figure 1 The structure of the straw packaging film is shown.

[0046] In some embodiments, the dotted line rolling cutter assembly 6 further includes a cylinder switch 607, which is connected to the cylinder 602. The cylinder switch 607 is used to control the on / off of the cylinder 602. When the indentation process is not being performed, the cylinder 602 is in the home position. In the home position, the dotted line rolling cutter 601 does not contact the film to be indented. Only when the cylinder switch 607 is turned on, the cylinder 602 lifts the cutter mounting plate 603 according to the set advancement distance, so that the dotted line rolling cutter 601 reaches its working position.

[0047] In some embodiments, as Figure 5 As shown, the indentation device of the straw packaging film also includes an equipment base 8 and an equipment back frame 9. The equipment back frame 9 is installed at the upper end of the equipment base 8. The equipment back frame 9 is used to fix the straw unwinding shaft 3, the straw pressing shaft 4, the indentation driven shaft 5 and the point breaking line rolling cutter assembly 6.

[0048] In some embodiments, as Figure 3 As shown, a straw winding shaft 10 is also fixed on the equipment back frame 9, and the straw winding shaft 10 is used to wind up the straw packaging film 11 that has been processed and broken.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
