DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The paper processing and trimming device according to the embodiment of the utility model will be described below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, the paper processing and trimming device of the embodiment of the utility model may include a trimming table 10 , a pre-pressing mechanism 20 and a trimming mechanism 30 .

[0024] The top surface of the trimming table 10 is provided with a first groove 11 , the side surface is provided with a second groove 12 , and the pre-pressing mechanism 20 is arranged in the first groove 11 .

[0025] It can be understood that the pre-pressing mechanism 20 can squeeze and limit the multi-layer corrugated paper placed in the first groove 11, so that the corrugated paper can be stably placed to ensure smooth cutting by the subsequent trimming mechanism 30.

[0026] The trimming mechanism 30 may include a connecting frame 31, a driving member 32 and a plurality of cutters 33, wherein the connecting frame 31 is arranged in an L shape, one end of the connecting frame 31 is movably arranged in the second groove 12, and the other end of the connecting frame 31 is extended above the trimming table 10. The plurality of cutters 33 are arranged in sequence on one side of the trimming table 10, and the cutting teeth of two adjacent cutters 33 are arranged in an interlaced meshing manner. A rotating shaft 331 is arranged in the middle of the cutter 33, and the lower side of the bottom cutter 33 is arranged below the top surface of the trimming table 10. The driving member 32 is arranged on the upper side of the connecting frame 31 through the housing 311, and the output end of the driving member 32 is connected to the plurality of rotating shafts 331.

[0027] It is understandable that the plurality of cutters 33 can move simultaneously, and in the process can perform edge trimming operations on the multiple layers of corrugated paper stacked in the first groove 11 .

[0028] It should be noted that the driving member 32 described in this embodiment can simultaneously drive the multiple rotating shafts 331 to rotate, thereby causing the multiple cutters 33 to rotate synchronously to perform cutting operations.

[0029] It should be noted that the second groove 12 described in this embodiment may be provided with a slide rail motor, a slide module, etc. for linearly moving the connecting frame 31 to facilitate linear movement of the cutter 33 .

[0030] It should be noted that the vertical height of the multiple cutters 33 described in this embodiment is greater than the vertical height of the stacked multiple layers of corrugated paper, so as to ensure smooth edge trimming operation of the stacked multiple layers of corrugated paper.

[0031] Specifically, when actually trimming the stacked multi-layer corrugated paper, the relevant personnel first place the stacked multi-layer corrugated paper in the first groove 11, and make one side of the corrugated paper rest against the side wall of the first groove 11, and make the end of the corrugated paper that needs to be trimmed be placed on the other side of the cutter 33, and then use the pre-pressing mechanism 20 to squeeze and limit the multi-layer corrugated paper so that the corrugated paper can be placed stably.

[0032] Then, the driving member 32 can simultaneously drive the multiple rotating shafts 331 to rotate, so that the multiple rotating shafts 331 drive the corresponding cutters 33 to rotate, and then the multiple cutters 33 can be linearly moved in the second groove 12. During the process, the multiple cutters 33 can cut the stacked multi-layer corrugated paper. The use of multiple cutters 33 can effectively divert the cutting pressure on the multi-layer corrugated paper, effectively reduce the collapse of the cutting edge caused by cutting, and improve the cutting quality. At the same time, multiple cutters 33 can improve the efficiency of cutting.

[0033] In one embodiment of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, the driving member 32 may include a plurality of driven wheels 321 , a synchronous belt 322 , a driving wheel 323 and a third driving component 324 .

[0034] Among them, a plurality of driven wheels 321 are sequentially arranged in the housing 311 from top to bottom, and a plurality of rotating shafts 331 are movably passed through the housing 311 and connected to the corresponding driven wheels 321. The synchronous belt 322 is respectively connected to the driving wheel 323 and the plurality of driven wheels 321, and the synchronous belt 322 is arranged in an S shape at the plurality of driven wheels 321. The third driving component 324 is connected to the driving wheel 323.

[0035] It should be noted that the third driving component 324 described in this embodiment can be a high-speed motor, a servo motor, etc. The third driving component 324 can drive the driving wheel 323 to rotate.

[0036] Specifically, when the relevant personnel use the driving member 32 to drive multiple rotating shafts 331 to rotate at the same time, the third driving component 324 can first drive the driving wheel 323 to rotate, and the driving wheel 323 can drive multiple driven wheels 321 to rotate synchronously through the synchronous belt 322, so that the multiple rotating shafts 331 drive the corresponding cutters 33 to rotate.

[0037] In one embodiment of the present invention, Figure 5 As shown, a cover 40 for protecting the cutting knife 33 is provided on the trimming table 10. It can be understood that the cover 40 can provide protection for the cutting knife 33 when it is not in use.

[0038] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the pre-pressing mechanism 20 may include a side pressing frame 21 and an upper pressing frame 22, wherein the side pressing frame 21 is arranged in the first groove 11 through a first driving component 211, and a plurality of side rods 212 arranged vertically and side by side are arranged on one side of the side pressing frame 21. The upper pressing frame 22 is arranged in the first groove 11 through a second driving component 221, and a plurality of upper rods 222 arranged horizontally and side by side are arranged on one side of the upper pressing frame 22, and the plurality of upper rods 222 are arranged alternately with the plurality of side rods 212.

[0039] The upper rod 222 and the side rod 212 are slidably connected to the first groove 11 respectively.

[0040] It should be noted that the first driving component 211 described in this embodiment can be a cylinder, a telescopic motor, etc. The first driving component 211 can drive the side pressure frame 21 to move horizontally.

[0041] It should be noted that the second driving component 221 described in this embodiment can be a cylinder, a telescopic motor, etc. The second driving component 221 can drive the upper press frame 22 to move vertically.

[0042] It is understandable that the upper rod 222 and the side rod 212 can be provided to quickly limit the position of paper products of different sizes, which is more flexible and convenient.

[0043] Specifically, when relevant personnel squeeze and limit the multi-layer corrugated paper through the pre-pressing mechanism 20, the first groove 11 has already limited the other side and lower side of the multi-layer corrugated paper. At this time, the side pressing frame 21 can be driven to move horizontally by the first driving component 211, and the upper pressing frame 22 can be driven to move vertically by the second driving component 221. During the process, multiple upper rods 222 and multiple side rods 212 run alternately, and squeeze and limit one side and upper side of the multi-layer corrugated paper in the first groove 11, thereby achieving stable placement of the corrugated paper.

[0044] In summary, the paper processing and trimming device of the embodiment of the utility model can effectively divert the cutting pressure exerted on multiple layers of corrugated paper by providing multiple cutters, thereby effectively reducing the collapse of the cutting edges caused by trimming, thereby improving the trimming quality, and multiple cutters can improve the efficiency of trimming.
