Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0032] See Figures 1 to 3The diagram shows a schematic representation of a packaging bag binding device 10 according to an embodiment of this application. The packaging bag binding device 10 provided in this embodiment includes a binding base 100 and a compression mechanism 200. Specifically, the binding base 100 serves as the supporting foundation for the packaging bag binding device 10 and has a binding cavity 110 for receiving the packaging bag. For example, the binding cavity 110 can be rectangular in shape to accommodate the shape of the packaging bag. The height and other dimensions of the binding cavity 110 should be greater than the height and other dimensions of the packaging bag in its open state to facilitate placing the packaging bag into the binding cavity 110. The compression mechanism 200 includes a first compression component 210 and a second compression component 220, which are respectively connected to the binding base 100 and extend into the binding cavity 110. Both the first compression component 210 and the second compression component 220 are configured to move within the binding cavity 110 to compress the packaging bag within the binding cavity 110. The first compression component 210 and the second compression component 220 move in different directions, so that the first compression component 210 and the second compression component 220 squeeze the packaging bag in different directions to compress the volume of the packaging bag.
[0033] Through the above structural design, the packaging bag bundling device 10 can automatically compress packaging bags via the compression mechanism 200, eliminating the need for manual pressing of the bags. This reduces the labor intensity of operators and improves convenience, speed, and efficiency when handling packaging bags. It also reduces the time spent on manual handling and bundling during the packaging process, while minimizing the area occupied by loose bundles. Multiple bundles of packaging bags can be transported at once, reducing the number of transport trips and saving labor. Furthermore, the first compression component 210 and the second compression component 220 apply pressure to the packaging bags from different directions, fully compressing the gaps inside the bags. This allows the bundling straps to fit more tightly into the bags during subsequent bundling, preventing the bundling from becoming loose. Therefore, the packaging bag bundling device 10 of this embodiment is convenient to operate, easy to transport, and beneficial for on-site management. It is suitable for the disposal of waste packaging bags after the use of can lids for various types of canned products, overcoming the tediousness, looseness, transport, and on-site management problems associated with manual handling of packaging bags.
[0034] Furthermore, in some embodiments, the first compression component 210 is configured to move within the binding cavity 110 along a first direction, and the second compression component 220 is configured to move within the binding cavity 110 along a second direction, wherein the second direction is perpendicular to the first direction. For example, the first compression component 210 and the second compression component 220 can simultaneously compress the packaging bag, or alternately compress it sequentially, to improve compression efficiency. In this embodiment, by having the first compression component 210 and the second compression component 220 compress the packaging bag within the binding cavity 110 from mutually perpendicular directions, compression dead zones can be avoided, ensuring uniform force distribution across all parts of the packaging bag, resulting in a more regular shape after compression, thereby reducing the volume of the packaging bag and further reducing the probability of loose binding.
[0035] Further, see Figures 1 to 3 As shown, in some embodiments, the first direction is parallel to the vertical direction, and the second direction is parallel to the horizontal direction. It should be noted that in this document, the vertical direction refers to the height direction (i.e., the direction of gravity) when the packaging bag binding device 10 is installed on the ground, and the horizontal direction refers to the width and thickness direction when the packaging bag binding device 10 is installed on the ground. For example, the first compression component 210 can be located at the top of the binding base 100, with its movement trajectory extending vertically. In this case, the gravity of the first compression component 210 can assist in compression, reducing the power load on the first drive component 211. Simultaneously, the first compression component 210 can directly compress the packaging bag to reduce the stacking height of the packaging bags. The second compression component 220 can be located on the side of the binding base 100, with its movement trajectory extending horizontally, to accommodate packaging bags of different widths and thicknesses, ensuring that packaging bags of different sizes can be compacted. Furthermore, the combined compression in the vertical and horizontal directions results in a more regular rectangular shape for the compressed packaging bag, which is more conducive to binding and transportation.
[0036] Further, see Figures 1 to 3As shown, in some embodiments, the first compression assembly 210 includes a first driving member 211 and a first compression plate 212. The first driving member 211 is connected to the binding base 100, and the first compression plate 212 is disposed within the binding cavity 110. The first driving member 211 and the first compression plate 212 are drivenly connected. The first driving member 211 is configured to drive the first compression plate 212 to move along a first direction to compress the packaging bag within the binding cavity 110. Specifically, the first driving member 211 is fixed on the binding base 100. The first driving member 211 can be powered by a cylinder, an electric push rod, or a servo motor, for example, a compression cylinder of specification FESTO DNC-50-700. The first compression plate 212 is a component that directly contacts the packaging bag. The size of the first compression plate 212 can be set to match the cross-sectional size of the binding cavity 110. For example, the first compression plate 212 can be set to a length of 125cm and a width of 75cm to ensure sufficient contact area. When the first driving component 211 is activated, it drives the first compression plate 212 to move linearly along the first direction, thereby applying pressure to the packaging bag inside the binding cavity 110 to achieve compression. The first driving component 211 can provide stable and continuous power, replacing manual pressing, making the compression operation simple, time-saving, and highly efficient.
[0037] Optionally, in some embodiments, there are multiple first driving members 211, which are spaced apart on the top of the binding base 100, and the output shaft of the first driving member 211 passes through the binding cavity 110. For example, see... Figures 1 to 3 As shown, two first driving members 211 are provided, arranged at intervals along the top of the binding base 100, and fixedly connected to the outer wall of the binding base 100. The output shaft of each first driving member 211 passes through the binding cavity 110 and is connected to the first compression plate 212. By superimposing the power of multiple first driving members 211, a greater compression force can be provided, and the simultaneous output of power by multiple first driving members 211 can make the thrust on the first compression plate 212 more uniform, ensuring that the first compression plate 212 always moves smoothly in the first direction. In addition, even if one of the first driving members 211 temporarily fails, the remaining first driving members 211 can still perform the compression function, avoiding a complete shutdown of the packaging bag binding equipment 10 and improving the reliability of the packaging bag binding equipment 10.
[0038] It should be understood that in other alternative embodiments, the number of first drive members 211 may be one, three, four or more.
[0039] Optionally, see Figure 2As shown, in some embodiments, the surface of the first compression plate 212 away from the first driving member 211 is a first plane 213, which is perpendicular to a first direction. Specifically, the surface of the first compression plate 212 away from the first driving member 211 is the surface that contacts the packaging bag, i.e., the first plane 213 is used to contact the packaging bag. Since the first plane 213 is perpendicular to the first direction, for example, when the first direction is parallel to the vertical direction, the first plane 213 is a horizontal plane. This flat first plane 213 contacts the packaging bag, allowing pressure to be evenly transmitted to every part of the packaging bag, avoiding the problem of loose binding caused by insufficient local pressure, ensuring that the compressed packaging bag is more compact, and preventing the binding from loosening.
[0040] Further, see Figures 1 to 3 As shown, in some embodiments, the second compression assembly 220 includes a second driving member 221 and a second compression plate 222. The second driving member 221 is connected to the binding base 100, and the second compression plate 222 is disposed within the binding cavity 110. The second driving member 221 is driven to the second compression plate 222, and the second driving member 221 is configured to drive the second compression plate 222 to move in a second direction to compress the packaging bag within the binding cavity 110. Specifically, the second driving member 221 is fixed to the binding base 100. The second driving member 221 can be powered by a cylinder, an electric push rod, or a servo motor, for example, a compression cylinder of specification FESTO DSBC-63-150-PPVA-N3. The second compression plate 222 is a component that directly contacts the packaging bag. The dimensions of the second compression plate 222 can be set to match the cross-sectional dimensions of the binding cavity 110. For example, the second compression plate 222 can be set to a length of 115cm and a height of 57cm to ensure sufficient contact area. When the second driving component 221 is activated, it drives the second compression plate 222 to move linearly along the second direction, thereby applying pressure to the packaging bag inside the binding cavity 110 to achieve compression. The second driving component 221 can provide stable and continuous power, replacing manual pressing, making the compression operation simple, time-saving, and highly efficient.
[0041] Optionally, in some embodiments, there are multiple second driving members 221, which are spaced apart on the side of the binding base 100, and the output shaft of the second driving member 221 passes through the binding cavity 110. For example, see... Figures 1 to 3As shown, two second driving members 221 are provided, spaced apart along the side of the binding base 100, and fixedly connected to the outer wall of the binding base 100. The output shaft of each second driving member 221 passes through the binding cavity 110 and is connected to the second compression plate 222. By superimposing the power of multiple second driving members 221, a greater compression force can be provided, and the simultaneous output of power by multiple second driving members 221 can make the thrust on the second compression plate 222 more uniform, ensuring that the second compression plate 222 always moves smoothly in the second direction. In addition, even if one of the second driving members 221 temporarily fails, the remaining second driving members 221 can still perform the compression function, avoiding a complete shutdown of the packaging bag binding equipment 10 and improving the reliability of the packaging bag binding equipment 10.
[0042] It should be understood that in other alternative embodiments, the number of second drive members 221 may be one, three, four or more.
[0043] Optionally, see Figure 1 As shown, in some embodiments, the surface of the second compression plate 222 away from the second driving member 221 is a second plane 223, which is perpendicular to the second direction. Specifically, the surface of the second compression plate 222 away from the second driving member 221 is the surface that contacts the packaging bag, i.e., the second plane 223 is used to contact the packaging bag. Since the second plane 223 is perpendicular to the second direction, for example, when the second direction is parallel to the horizontal direction, the second plane 223 is a vertical plane. This flat second plane 223 contacts the packaging bag, allowing pressure to be evenly transmitted to every part of the packaging bag, avoiding the problem of loose binding caused by insufficient local pressure, ensuring that the compressed packaging bag is more compact, and preventing the binding from loosening.
[0044] Further, see Figures 1 to 3 As shown, in some embodiments, the binding base 100 has a frame structure with binding gaps 120 for binding straps to pass through. For example, the binding base 100 can be a metal frame, and the internal space of the frame is the binding cavity 110. The frame structure is formed by multiple square tubes connected together on all four sides and the top, with binding gaps 120 formed between adjacent square tubes, making the binding gaps 120 elongated slots. When the packaging bag is compressed, the binding strap is passed through the binding gap 120 from one side of the binding base 100, wraps around the packaging bag, and then passes out through the binding gap 120 on the other side of the binding base 100, thus effectively binding the packaging bag. Therefore, the binding gaps 120 on the binding base 100 can provide a channel for the binding strap to be reserved in the binding cavity 110. The binding strap can be made of nylon rope, cable ties, etc. In practical applications, after the compression is completed, the packaging bag is manually bound using the binding straps reserved in the binding cavity 110, so that the bound packaging bags can be stacked stably and conveniently placed in the warehouse.
[0045] Furthermore, in some embodiments, at least one side of the binding base 100 is provided with a cover 300, the cover 300 being rotatably connected to the binding base 100 and forming a binding cavity 110 with the binding base 100. For example, see... Figures 1 to 3 As shown, the binding base 100 has openings and a cover 300 on both opposite sides. The size of the cover 300 is adapted to the size of the opening of the binding base 100, ensuring that it completely covers the opening when closed. The cover 300 is located in the upper part of the binding base 100 and is rotatably connected to the binding base 100, for example, by a hinge, for easy insertion or removal of packaging bags. Furthermore, the cover 300 can be locked by a buckle or manual lock after closing, ensuring that the cover 300 will not open due to pressure during compression. After the cover 300 is closed and locked, the cover 300 and the binding base 100 together form a binding cavity 110, ensuring that the packaging bag is contained within the binding cavity 110. Therefore, by providing the cover 300, the insertion and removal of packaging bags are more convenient, and it is also convenient to replenish packaging bags during compression, improving operational ease of use.
[0046] It should be understood that in other alternative embodiments, an opening and a cover 300 may be provided only on one side of the binding base 100, or an opening and a cover 300 may be provided on more sides of the binding base 100 to allow for the loading and unloading of packaging bags.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
