At the same time, it should be understood that for the convenience of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] As Figures 1 to 3 shown, applying the technical solution of this embodiment, the punching device includes a connecting beam 10 and a punching member. The connecting beam 10 is detachably connected to the floating device 50. The punching member is connected to the connecting beam 10 with adjustable position. The punching member has a plurality of punching needles.

[0031] In this way, when the floating device 50 floats, it can drive the punching member to float up and down through the connecting beam 10, so that the plurality of punching needles on the punching member can perform punching operations on the bag body. Moreover, the detachable connection between the connecting beam 10 and the floating device 50 facilitates the installation and disassembly of the punching device on the floating device 50, and facilitates the operator to choose whether to install the punching device according to actual needs. The adjustable position of the punching member and the connecting beam 10 enables the position of the punching needles relative to the connecting beam 10 to be adjustable, so as to facilitate adjusting the punching needles to the position where the punching needles can contact the bag body when the connecting beam 10 presses down. In this way, the operation of replacing the connecting beam 10 is avoided, and only the punching member needs to be replaced, making the operation relatively simple and reducing the cost. Therefore, the technical solution of this embodiment effectively solves the problem that the operation is relatively troublesome when the operator replaces the punching member in the related art.

[0032] As Figures 1 to 3 shown, a first adjustment hole 11 extending in the horizontal direction is provided on the connecting beam 10, and the punching member is movably arranged in the first adjustment hole 11. In this way, through the setting of the first adjustment hole 11, the position of the punching member relative to the connecting beam 10 in the horizontal direction is adjustable, so that the position between the punching member and the floating device 50 can be adjusted, facilitating the adjustment of the punching position of the punching member on the bag body, making the punching operation more accurate, and improving the adaptability of the punching member.

[0033] In this embodiment, the bag-making device further includes a conveying device 60. The floating device 50 is floatingly arranged above the conveying device 60. The floating device 50 floats to drive the punching member to float above the conveying device 60 through the connecting beam 10. The connecting beam 10 extends along the conveying direction of the conveying device 60, and the punching member is located on one side of the floating device 50.

[0034] As Figures 1 to 3 shown, the punching member includes a needle plate 21 and a connecting member connected between the needle plate 21 and the connecting beam 10. A plurality of punching needles are arranged on the side of the needle plate 21 facing away from the connecting member, and the connecting member is adjustably connected to the connecting beam 10. The structures of the needle plate 21 and the connecting member are simple, which is convenient for the processing of the punching member. The needle plate 21 is convenient for arranging the punching needles, and the connecting member is convenient for connecting the needle plate 21 and the connecting beam 10.

[0035] As Figures 1 to 3 shown, the punching member further includes a first fastener 30, and a second adjustment hole 222 extending in the vertical direction is provided on the punching member. The first fastener 30 is inserted into the first adjustment hole 11 and the second adjustment hole 222 to fixedly connect the punching member and the connecting beam 10. The setting of the second adjustment hole 222 enables the first fastener 30 to move within the second adjustment hole 222 to adjust the position of the punching member in the vertical direction, so that the punching member can be adjusted to a position where the punching needles can contact the bag body when the connecting beam 10 presses down. Inserting the first fastener 30 into the first adjustment hole 11 and the second adjustment hole 222 enables the operator to adjust the position of the punching member in the vertical direction and the horizontal direction by adjusting the fastening state of the first fastener 30, further improving the convenience of operation.

[0036] As Figures 1 to 3 shown, the connecting member includes a plate body 221 and a connecting frame connected between the plate body 221 and the needle plate 21, and the second adjustment hole 222 is provided on the plate body 221. The structures of the plate body 221 and the connecting frame are simple, which is convenient for processing. And the setting of the connecting frame improves the structural strength of the connecting member, and reduces the swing of the connecting member when the punching member floats up and down, making the punching operation of the punching member more accurate.

[0037] As Figures 1 to 3As shown, the connecting frame includes a first plate segment 223, a second plate segment 224, and a third plate segment 225. The first plate segment 223 and the second plate segment 224 are arranged oppositely, and the first ends of the first plate segment 223 and the second plate segment 224 are both connected to the needle plate 21. The third plate segment 225 is connected between the second ends of the first plate segment 223 and the second plate segment 224, and the plate body 221 is connected to the third plate segment 225. The structures of the first plate segment 223, the second plate segment 224, and the third plate segment 225 are simple and convenient for processing. The settings of the first plate segment 223 and the second plate segment 224 can increase the contact area between the connecting member and the needle plate 21, making the connection between the connecting frame and the needle plate 21 more reliable. Connecting the plate body 221 to the third plate segment 225 can make the force on the connecting frame more uniform, and further reduce the swing of the connecting member when the punching member floats up and down.

[0038] As Figures 1 to 3 shown, there are multiple punching members, and the arrangements of the multiple punching needles on each punching member are different. One of the multiple punching members can be selectively connected to the connecting beam 10. In this way, the operator can select different punching members to be connected to the connecting beam 10 according to different product requirements, so as to punch different holes through the arrangements of different punching needles. Moreover, applying the technical solution of this embodiment, only by replacing the punching member, the arrangement of the holes on the bag body can be changed, making the operation simpler and improving the work efficiency.

[0039] It should be noted that the different arrangements of the multiple punching needles on each punching member refer to: the multiple punching needles on each punching member form multiple needle groups, and the shapes formed by the multiple needle groups are different; or, the multiple punching needles on each punching member form multiple needle groups, and the positions of the multiple needle groups on the needle plate 21 are different; or, the distances between adjacent two punching needles among the multiple punching needles on different punching members are different; or, the numbers of punching needles on different punching members are different.

[0040] In this embodiment, the multiple punching needles on the punching member form four needle groups. The needle plate 21 is rectangular, and the four needle groups are respectively arranged at the four corners of the rectangle. The four needle groups are the first needle group 231, the second needle group 232, the third needle group 233, and the fourth needle group 234 arranged adjacent to each other. An avoidance space for avoiding the marks on the bag body is formed among the first needle group 231, the second needle group 232, the third needle group 233, and the fourth needle group 234. The punching needles in the first needle group 231 are arrayed to form a triangle, and the punching needles in the second needle group 232, the third needle group 233, and the fourth needle group 234 are respectively arrayed to form a trapezoid. Moreover, the projection area formed by the first needle group 231 on the needle plate 21 is the smallest, and the projection area formed by the third needle group 233 arranged opposite to the first needle group 231 on the needle plate 21 is the largest.

[0041] As Figures 1 to 3As shown, the punching device further includes a fixing member for connecting the connecting beam 10 to the floating device 50. The fixing member is fixedly connected to the connecting beam 10 and detachably connected to the floating device 50. The setting of the fixing member facilitates the fixed connection and disassembly of the connecting beam 10 and the floating device 50, with simple operation and convenient processing. Fix the fixing member on the floating device 50 to fixedly connect the connecting beam 10 and the floating device 50. Remove the fixing member from the floating device 50 to enable the connecting beam 10 to be separated from the floating device 50.

[0042] As Figures 1 to 3 shown, the fixing member includes a first fixing plate 41, a second fixing plate 42 and a second fastener 43. The first fixing plate 41 and the second fixing plate 42 are arranged at an angle, and the first fixing plate 41 is fixedly connected to the connecting beam 10. The second fixing plate 42 is provided with an avoidance hole, and the second fastener 43 is passed through the avoidance hole to fixedly connect the second fixing plate 42 and the floating device 50. The setting of the first fixing plate 41 makes the connection between the fixing member and the connecting beam 10 more stable and reliable. The avoidance hole on the second fixing plate 42 and the setting of the second fastener 43 make the installation and disassembly of the second fixing plate 42 and the floating device 50 more convenient and fast. The first fixing plate 41 and the second fixing plate 42 are arranged at an angle, which is convenient for the operator to operate the second fastener 43 and makes the structure of the fixing member more compact.

[0043] In this embodiment, the connecting beam 10 is connected to the upper surface of the first fixing plate 41, and the lower surface of the first fixing plate 41 is attached to the upper surface of the floating device 50. The second fixing plate 42 is attached to the side wall of the floating device 50.

[0044] The present application also provides a bag-making device, which includes a floating device 50. The bag-making device further includes a punching device, and the punching device is the above-mentioned punching device. Since the above-mentioned punching device can solve the problem that the operation is relatively troublesome when the operator replaces the punching part in the related art, the bag-making device with this punching device can solve the same technical problem.

[0045] In this embodiment, the floating device 50 includes a heat-sealing structure that is floatingly arranged above the conveying device 60. The connecting beam 10 is detachably connected to the heat-sealing structure, and the punching part is located downstream of the heat-sealing structure.

[0046] In other embodiments, the floating device 50 includes a cutting device that is floatingly arranged above the conveying device 60. The connecting beam 10 is detachably connected to the cutting device.

[0047] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0048] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0049] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without separate declaration, the above words have no special meaning. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0050] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
