[0043] Example 1

[0044] In view of the aforementioned deficiencies in existing cross-cutting blade modules, the applicant, drawing upon years of extensive practical experience and expertise in the design and manufacture of such products, combined with the application of academic theory, has actively engaged in research and innovation, hoping to create a technology that can address the deficiencies of the existing technology and make cross-cutting blade modules more practical. Through continuous research and design, as well as repeated trial production and improvements, the applicant has finally created the present utility model, which is truly practical.

[0045] Please refer to Figures 1 to 4 An embodiment of the utility model provides a cross-cutting knife module, including a sliding frame 1 that can slide back and forth along a set direction, a cross-cutting knife assembly 2 installed on the sliding frame 1, and a pressure wheel assembly 3 installed on the sliding frame 1; the sliding frame 1 supports the cross-cutting knife assembly 2 and the pressure wheel assembly 3.

[0046] Two pressing wheel assemblies 3 are provided, and the two pressing wheel assemblies 3 are installed on opposite sides of the cross-cutting knife assembly 2; the cross-cutting knife assembly 2 includes a rotating blade 21 for cutting cardboard, and the pressing wheel assembly 3 includes a pressing wheel 31 for pressing creases on the cardboard, and the rotation center line of the pressing wheel 31 is parallel to the rotation center line of the rotating blade 21.

[0047] In this embodiment, the slide 1 moves in a set direction or in a direction opposite to the set direction, so that the cross-cutting knife assembly 2 can cut the required cuts on the cardboard horizontally, and during the paper cutting process of the rotating blade 21, the pressure wheel 31 simultaneously presses the required folds on the cardboard. Generally, during a cutting process, the center line of the cross-cut cut made by the rotating blade 21 and the center line of the fold pressed by the pressure wheel 31 coincide with each other. Of course, considering some special carton structures, the center line of the cross-cut cut and the center line of the fold pressed by the pressure wheel 31 do not need to coincide, that is, the center line of the cross-cut cut and the center line of the fold pressed by the pressure wheel 31 only need to be parallel to each other.

[0048] In this embodiment, after the cardboard is positioned once, the cross-cutting knife module can cut the required cross-cutting cuts and press out the required transverse indentations, which reduces the time for cardboard transfer and re-positioning, and improves the production efficiency of cartons to a certain extent.

[0049] Optionally, the cross-cutting knife module further includes a frame 100, which is provided with horizontal rails 200, on which the sliding frame 1 is slidably mounted. A drive device 4 is also mounted on the frame 100 for driving the sliding frame 1 along the horizontal rails 200. Specifically, the drive device 4 can drive the sliding frame 1 along the horizontal rails 200 to meet actual production needs. Driven by the drive device 4, the sliding frame 1 can slide from left to right or from right to left.

[0050] Alternatively, the drive device 4 includes a drive motor 41, a first synchronous pulley, a second synchronous pulley, and a synchronous belt 42 tensioned between the first and second synchronous pulleys. The drive motor 41 is in driving connection with the first synchronous pulley. The slide frame 1 includes a pressure plate 101 and a clamping plate 102 detachably mounted on the pressure plate 101. The pressure plate 101 and the clamping plate 102 cooperate to clamp the synchronous belt 42. In this embodiment, the drive motor 41 rotates the first synchronous pulley, thereby rotating the synchronous belt 42, which in turn drives the slide frame 1 to slide along the horizontal rail 200. In this embodiment, the drive motor 41 can rotate in both forward and reverse directions.

[0051] Optionally, the cross-cutting blade assembly 2 further includes a first telescopic device 22, a first fixed seat 23, and a cross-cutting motor 24; the first fixed seat 23 is fixedly connected to the telescopic shaft of the first telescopic device 22, and the rotary blade 21 is rotatably mounted on the first fixed seat 23 via a rotating shaft. The cross-cutting motor 24 can drive the rotating shaft to rotate, thereby driving the rotary blade 21 to rotate to cut the cardboard. It should also be noted that during the actual cutting process, the height of the rotary blade 21 can be controlled to control the rotary blade 21 to cut or stop cutting the cardboard. When only the pressure wheel 31 is needed to press a crease, the rotary blade 21 can be raised so that the rotary blade 21 no longer contacts the cardboard, that is, only the pressure wheel 31 presses against the cardboard.

[0052] Optionally, the pressure wheel assembly 3 further includes a second telescopic device 32 and a second fixed seat 33. The second fixed seat 33 is fixedly connected to the telescopic axis of the second telescopic device 32. The telescopic axis of the first telescopic device 22 and the second telescopic device 32 are parallel to each other, and the first telescopic device 22 is electrically connected to the second telescopic device 32. The second fixed seat 33 is mounted with a fixed axis, and the pressure wheel 31 is rotatably mounted on the fixed axis. Specifically, in areas where only cross-cuts are required, the pressure wheel 31 can be raised to avoid pressing against areas where creases are not required.

[0053] Optionally, the first telescopic device 22 and the second telescopic device 32 are both cylinders.

[0054] Optionally, in this embodiment, the diameter of the paper pressing wheel 31 is not less than the maximum outer diameter of the rotating blade 21 .

[0055] Optionally, a press roller assembly 5 is also mounted on the frame 100. The press roller assembly 5 includes a third telescopic device 51, a third fixed seat 52, a press roller 53, and a press roller drive assembly for rotating the press roller 53. The third fixed seat 52 is mounted on the telescopic shaft of the third telescopic device 51. The press roller 53 is rotatably mounted on the third fixed seat 52, and the centerline of the press roller 53 is perpendicular to the centerline of the rotating blade 21. The press roller 53 rotates under the drive of the press roller drive assembly, thereby moving the cardboard forward to meet the needs of subsequent feeding. It should also be noted that the press roller assembly 5 and the cross-cutting knife assembly 2 are arranged in sequence and spaced apart along the conveying direction of the cardboard. The driving member of the press roller drive assembly can be a motor or other rotary drive device.

[0056] Optionally, the paper pressing wheel 31 includes a middle portion and a paper pressing portion surrounding the middle portion; the farther the paper pressing portion is from the center line of the paper pressing wheel 31 , the smaller its width is, and both opposite side surfaces of the paper pressing portion are arc surfaces.

[0057] Example 2

[0058] This embodiment discloses a paper trimmer including the cross-cutting knife module as described in any one of the above items.

[0059] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
