It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present application. When introducing the elements / components / etc. described and / or illustrated herein, the terms "comprising", "including" and "having" are used to represent the meaning of open-ended inclusion and mean that in addition to the listed elements / components / etc., there may be additional elements / components / etc.

[0066] like Figures 1 to 3 As shown, the wireless book pre-cutting device 1 of the present application includes a lever structure 10, a pre-cutting knife 20 and a driving block 30. The pre-cutting knife 20 is arranged at one end of the lever structure 10. The driving block 30 is arranged at the other end of the lever structure 10 and drives the lever structure 10 to move. The driving block 30 drives the pre-cutting knife 20 to move in a direction away from the driving block 30 through the lever structure 10 to pre-cut the wireless book 400.

[0067] The wireless book pre-cutting device 1 of the present application adopts a lever structure 10 and a driving block 30, so that the driving block 30 can drive the pre-cutting knife 20 through the lever structure 10 to pre-cut a small opening in the wireless book 400, and then the cutting knife 200 formally cuts the wireless book 400 along the small opening, thereby avoiding the situation where there is no support point at the back of the wireless book 400 at the incision position, which will cause cracks and damages to the back of the wireless book 400 due to the external force of the cutting knife 200.

[0068] In this embodiment, the lever structure 10 includes a follower 11, a rod body 12 and a pivot 13. The follower 11 moves with the movement of the driving block 30. One end of the rod body 12 fixes the follower 11, and the other end is connected to the pre-cutter 20. The pivot 13 passes through the rod body 12, and the follower 11 and the pre-cutter 20 can rotate around the pivot 13. By connecting the follower 11 at one end of the lever and the pre-cutter 20 at the other end, the follower 11 can drive the pre-cutter 20 to move when rotating around the pivot 13, thereby realizing the pre-cutting of the wireless book 400.

[0069] In this embodiment, the driving block 30 includes a driving surface 31, the driving surface 31 contacts the follower 11, and the driving surface 31 can drive the follower 11 to rotate around the pivot 13 in a direction away from the driving surface 31. The setting of the driving surface 31 makes the movement of the follower 11 rotate around the pivot 13 in a direction away from the driving surface 31, so that the pre-cutting knife 20 can be driven to move through the lever structure 10. Among them, the driving surface 31 is a continuous concave arc surface; the concave arc surface is easy to process, and can make the movement of the follower 11 smoother and more continuous, so that the pre-cutting movement of the pre-cutting knife 20 is more stable, and the pre-cutting effect of the wireless book 400 is better. In some other embodiments, the driving surface 31 can also be an inclined surface.

[0070] In this embodiment, the wireless pre-cutting device 1 further includes a bracket 21 and a pull rod 22, the pivot 13 passes through the bracket 21, and the pull rod 22 is fixed to the bracket 21. The bracket 21 provides support for the pivot 13, and the pull rod 22 on the bracket 21 is a continuation of the bracket 21.

[0071] In this embodiment, the wireless pre-cutting device 1 further includes a first elastic member 23, one end of the first elastic member 23 is connected to the rod body 12 and is close to the pre-cutting knife 20, and the other end is connected to the pull rod 22. The first elastic member 23 makes the follower 11 always fit the driving block 30. The first elastic member 23 is a spring, and further a tension spring. The first elastic member 23 is arranged at one end of the pull rod 22 and the rod body 12 close to the pre-cutting knife 20, so that the follower 11 fixed to the other end of the rod body 12 always fits the driving surface 31.

[0072] In this embodiment, the wireless pre-cutting device 1 further includes a support bar 60, one end of the bracket 21 is connected to the pivot 13, and the other end is connected to a guide post 24, the guide post 24 passes through the bracket 21, and the guide post 24 is fixed to the support bar 60 by a connecting block 61. The support bar 60 can support the wireless pre-cutting device 1 on the frame 100, and the guide post 24 can be fixed to the frame 100 by the connecting block 61.

[0073] In this embodiment, the bracket 21 can move along the guide column 24, and a second elastic member 25 is provided between the bracket 21 and the connecting block 61, and the second elastic member 25 can drive the bracket 21 to move in a direction away from the connecting block 61. The second elastic member 25 is a compression spring, and the second elastic member 25 applies pressure to the bracket 21, so that the bracket 21 can move downward along the guide column 24.

[0074] In this embodiment, the axis direction of the pivot 13 is perpendicular to the axis direction of the guide post 24. In this way, the pre-cutting knife 20 can move through the lever structure 10 to pre-cut the wireless notebook 400.

[0075] In this embodiment, a limit ring 26 is provided at one end of the guide post 24 away from the connecting block 61, and the limit ring 26 limits the bracket 21. The setting of the limit ring 26 makes the bracket 21 no longer move downward, so that the downward movement of the driving block 30 can drive the follower 11 to rotate around the pivot 13, driving the pre-cutting knife 20 to pre-cut the wireless notebook 400.

[0076] In this embodiment, the wireless book pre-cutting device 1 further includes a transition plate 40 and a fixing frame 50, wherein the transition plate 40 is connected to the driving block 30 and can move synchronously with the driving block 30, and the fixing frame 50 is connected to the transition plate 40. The transition plate 40 and the fixing frame 50 can fix the wireless book pre-cutting device 1 to the pressing structure 300, so that the structures required for pre-cutting and cutting can be associated and fixed, so that the wireless book 400 can be cut in time after pre-cutting, thereby improving production efficiency.

[0077] In this embodiment, the wireless pre-cutting device 1 further includes a reset hook block 27, which is a bent piece, one end of which is fixed to the transition plate 40, and the other end of which is in contact with or separated from the bracket 21; when the other end of the reset hook block 27 is in contact with the bracket 21, the reset hook block 27 drives the bracket 21 to reset; when the other end of the reset hook block 27 is separated from the bracket 21, the transition plate 40 drives the reset hook block 27 to move. The setting of the reset hook block 27 resets the states of the various components of the entire device after movement, preparing for the next pre-cutting and cutting. Figure 1 and Figure 2 The reset hook block 27 in FIG. 1 only shows a half structure.

[0078] like Figures 4 to 7As shown, the wireless book cutting device 1 of the present application includes a cutting knife 200, a square pressing structure 300 and the above wireless book pre-cutting device 1, wherein the square pressing structure 300 is fixed to the driving block 30 and can drive the driving block 30 to move, the cutting knife 200 is fixed to the square pressing structure 300, and the cutting edges of the cutting knife 200 and the pre-cutting knife 20 are in a straight line. During the cutting process of the wireless book 400, the pre-cutting knife 20 contacts the wireless book 400 before the cutting knife 200. The pre-cutting knife 20 and the cutting knife 200 are installed in a straight line, and the pre-cutting knife 20 contacts the wireless book 400 before the cutting knife 200, so that the wireless book 400 can be cut with a small opening by the pre-cutting knife 20 first, and then the cutting knife 200 can formally cut, thereby improving the cutting quality, avoiding cutting breaks, and improving the cutting qualification rate.

[0079] In this embodiment, the pressing structure 300 includes a pressing block 302 and a pressing base 301. The pressing base 301 is fixedly connected to the driving block 30. The pressing block 302 is fixed to the pressing base 301. The pressing block 302 presses the wireless notebook 400 to facilitate cutting the wireless notebook 400. After the pressing block 302 presses the wireless notebook 400, the pre-cutting knife 20 and the cutting knife 200 cut the wireless notebook 400. The pressing block 302 presses the wireless notebook 400 through the movement of the pressing base 301.

[0080] In this embodiment, the wireless notebook cutting device 2 further includes: a notebook blocking mechanism 500, which blocks the wireless notebook 400. In order to make the cutting size of the wireless notebook 400 more standardized, the baffle mechanism 500 is provided to block the wireless notebook 400, thereby ensuring the cutting quality.

[0081] In this embodiment, the wireless notebook cutting device 2 further includes: a knife holder horizontal axis 600, which passes through the square pressing base 301. The knife holder horizontal axis 600 passes through the square pressing base 301, which can apply uniform pressure to the square pressing base 301, which is beneficial to the cutting of the wireless notebook 400. Figure 6 The reset hook block 27 in FIG. 1 only shows a half structure.

[0082] In this embodiment, the wireless notebook 400 is disposed on the support structure 700. The support structure 700 is in a downward or descending direction relative to the wireless notebook 400, and the wireless notebook 400 is in an upward or ascending direction relative to the support structure 700.

[0083] like Figure 8 As shown, another embodiment 3 of the wireless cutting device of the present application is Figures 4 to 7 The embodiments of the present invention have substantially the same structure in the basic structure. Therefore, in the following Figure 8 In the description of the implementation method of Figures 4 to 7 In addition, Figures 4 to 7 The same reference numerals are used to denote the same structures as those described in the embodiment of the present invention. Figures 4 to 7 The differences between the wireless cutting knife 400 and the cutting knife 200 are described below.

[0084] In this embodiment, two blocking mechanisms 500 are provided along the support bar 60. In fact, in production, multiple wireless cutting devices 2 can be provided along the support bar 60. Usually, one wireless cutting device 2 corresponds to one blocking mechanism 500. Figure 8 Only two blocking mechanisms 500 and one wireless cutting device 2 are shown, and another wireless cutting device 2 is not shown. That is, the frame 100 supports the support bar 60, and multiple wireless cutting devices 2 can be arranged on the support bar 60, corresponding to multiple blocking mechanisms 500. Figure 8 The embodiment is another embodiment 3 of a wireless cutting device formed by two wireless cutting devices 2 (one of which is not shown).

[0085] In this exemplary embodiment, the wireless notebook pre-cutting device 1 and the wireless notebook cutting devices 2 and 3 proposed in this application are described by taking the field of stationery as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of this application to other fields, various modifications, additions, substitutions, deletions or other changes are made to the following specific embodiments, and these changes are still within the scope of the principles of the wireless notebook pre-cutting device 1 and the wireless notebook cutting devices 2 and 3 proposed in this application.

[0086] It should be noted here that the wireless pre-cutting device 1 and the cutting devices 2, 3 shown in the drawings and described in this specification are only a few examples of many wireless pre-cutting devices 1 and cutting devices 2, 3 that can adopt the principles of the present application. It should be clearly understood that the principles of the present application are by no means limited to any component of any detail of the wireless pre-cutting device 1 and the cutting device 2, 3 shown in the drawings or described in this specification.

[0087] The above is a detailed description of several exemplary embodiments of the wireless pre-cutting device 1 and the cutting devices 2, 3 proposed in the present application. The following is an exemplary description of the use process of the wireless pre-cutting device 1 and the cutting devices 2, 3 proposed in the present application.

[0088] Combined with Figures 1 to 8 The use process of the wireless pre-cutting device 1 and the cutting devices 2 and 3 proposed in this application is as follows.

[0089] The tool holder horizontal axis 600 drives the pressing structure 300 to descend, thereby driving the driving block 30 and the reset hook block 27 fixed to the driving block 30 to descend together. At this time, since the reset hook block 27 leaves the bracket 21 due to the descent, the bracket 21 moves downward along the guide column 24 under the action of the second elastic member 25, so that the pull rod 22 fixed to the bracket 21 also moves downward. The lever structure 10 is fixed to the bracket 21 through the pivot 13, so the downward movement of the bracket 21 can drive the lever structure 10 to move downward as a whole. During this movement, due to the action of the first elastic member 23, the follower 11 of the lever structure 10 always fits the driving surface 31 of the driving block 30.

[0090] When the bracket 21 moves downward along the guide column 24 until it contacts the limit ring 26, the bracket 21 stops moving downward due to the limit action of the limit ring 26, so the pull rod 22 and the pivot 13 of the lever structure 10 also stop moving downward. At this time, the tool holder horizontal axis 600 still drives the square pressing structure 300 to continue to descend, so that the driving block 30 also continues to descend, and the pressing block 302 of the square pressing structure 300 will press the wireless book 400. At this time, since the follower 11 of the lever structure 10 is in contact with the driving surface 31 of the driving block 30, when the pivot 13 of the lever structure 10 no longer moves, the descent of the driving block 30 will drive the follower 11 of the lever structure 10 to rise along the driving surface 31 and rotate around the pivot 13, so that the pre-cutting knife 20 at the other end of the lever structure 10 descends and cuts a small hole in the wireless book 400 before the cutting knife 200.

[0091] Afterwards, the horizontal axis 600 of the knife holder continues to descend, driving the cutting knife 200 to complete the cutting of the wireless notebook 400 along the small opening cut by the pre-cutting knife 20 .

[0092] After cutting is completed, the knife holder horizontal axis 600 rises, driving the cutting knife 200 to rise, and also driving the driving block 30 to rise, and the follower 11 is reset along the driving surface 31, and the pre-cutting knife 20 is reset. The knife holder horizontal axis 600 continues to rise, and continues to drive the reset hook block 27 to rise together, so that the reset hook block 27 contacts the bracket 21, and drives the bracket 21 to overcome the elastic force of the second elastic member 25 and then rise to return to the initial position.

[0093] Through the above-mentioned use process of the wireless notebook pre-cutting device and cutting device of the present application, it can be concluded that the wireless notebook pre-cutting device and cutting device of the present application can pre-cut the wireless notebook and then cut it, and the wireless notebook is not prone to cracks and damage.

[0094] In summary, the wireless book pre-cutting device proposed in the present application includes a lever structure, a pre-cutting knife and a driving block. The pre-cutting knife is arranged at one end of the lever structure. The driving block is arranged at the other end of the lever structure and drives the lever structure to move. Among them, the driving block drives the pre-cutting knife to move in a direction away from the driving block through the lever structure to pre-cut the wireless book. This avoids the situation where the cutting knife directly cuts the wireless book, and there is no support point on the back of the wireless book at the incision position, which will easily cause cracks on the back of the wireless book due to external force squeezing, resulting in damage to the back of the wireless book.

[0095] The wireless notebook cutting device proposed in the present application includes a cutting knife, a square pressing structure and the above wireless notebook pre-cutting device, wherein the square pressing structure is fixed to the driving block and can drive the driving block to move, the cutting knife is fixed to the square pressing structure, the cutting knife and the pre-cutting knife are on a straight line, and during the wireless notebook cutting process, the pre-cutting knife contacts the wireless notebook before the cutting knife. The pre-cutting knife first cuts a small hole in the wireless notebook, and then the cutting knife cuts. The wireless notebook after cutting is not easy to be broken or damaged, which improves the qualified rate of wireless notebook cutting products, improves production efficiency, and reduces production costs.
