[0034] Further, the device body 1 adopts the longitudinal and latitudinal cutting machine in the prior art, which has the advantages of mature technology and stable work. The longitudinal moving mechanism 2 and the latitudinal moving mechanism 3 are both configured as linear rail electric sliders on the longitudinal and latitudinal cutting machine. The longitudinal moving mechanism 2 can drive the cutting mechanism 4 and the pressing mechanism 5 to move longitudinally. The longitudinal moving mechanism 2 has a transverse guide rail 201, and the latitudinal moving mechanism 3 is installed on the transverse guide rail 201. The latitudinal moving mechanism 3 can drive the cutting mechanism 4 and the pressing mechanism 5 to move latitudinally.
[0035] It should be noted that the bottom of the latitudinal moving mechanism 3 is provided with a lifting cylinder, and the bottom of the lifting cylinder is provided with an electric control rotary table. This part of the technology is in the prior art, and therefore will not be described in detail. The cutting mechanism 4 and the pressing mechanism 5 are connected with the electric control rotary table. The lifting cylinder of the latitudinal moving mechanism 3 can drive the cutting mechanism 4 and the pressing mechanism 5 to vertically lift, so as to realize the functions of lowering and lifting the cutting knife. The electric control rotary table of the latitudinal moving mechanism 3 can drive the cutting mechanism 4 and the pressing mechanism 5 to rotate, so as to adjust the cutting angle.
[0036] In some embodiments of the present embodiment, as shown in Figure 1 、 Figure 2 , the cutting mechanism 4 comprises a cutting blade 401 and a mounting frame 402. The mounting frame 402 is fixedly connected with the latitudinal moving mechanism 3. The rotating shaft of the cutting blade 401 is connected with the mounting frame 402. A motor on the mounting frame 402 drives the rotating shaft of the cutting blade 401 to rotate, thereby driving the cutting blade 401 to rotate and play a cutting role.
[0037] Further, as shown in Figure 1 、 Figure 2 and Figure 3 , the pressing mechanism 5 comprises an elastic member 501 and a pressing track 502. The elastic member 501 pushes the pressing track 502 downward by the rebound force after being compressed, so as to push the pressing track 502 to tightly abut against the paperboard 8 below.
[0038] As shown in Figure 2 and Figure 3 , the elastic member 501 comprises a sleeve 5011, a guide column 5012 and a spring 5013. The sleeve 5011 is fixedly connected with the bottom of the latitudinal moving mechanism 3. The guide column 5012 is inserted into the bottom end of the sleeve 5011. The spring 5013 is installed inside the sleeve 5011 and is in a compressed state, so as to exert a vertical downward pushing force on the top end of the guide column 5012.
[0039] It should be noted that, as shown in Figure 3As shown in the figure, the sleeve 5011 and the guide column 5012 are shown in cross section, the side of the guide column 5012 is provided with a vertical strip-shaped sliding groove, the inner wall of the sleeve 5011 is provided with a sliding block inserted into the strip-shaped sliding groove, and the sliding block can slide relatively along the strip-shaped sliding groove. The displacement stroke of the guide column 5012 is limited by the cooperation of the strip-shaped sliding groove and the sliding block, and the sleeve 5011 and the guide column 5012 can also be prevented from being separated.
[0040] In some embodiments of the present embodiment, in combination with Figure 2 and Figure 3 As shown, the two elastic members 501 are symmetrically installed compared to the cutting blade 401, and the corresponding compression track 502 is also symmetrically installed compared to the cutting blade 401. When cutting the paperboard 8, the compression tracks 502 on both sides press the paperboard 8 on both sides of the cutting blade 401, which prevents the paperboard 8 from arching and improves the effect.
[0041] As shown in Figure 2 and Figure 3 The compression track 502 mainly includes a cross beam 5021, a rotating wheel 5022 and a compression belt 5023. The cross beam 5021 is made of aluminum alloy and has the advantages of light weight and high strength. The two ends of the cross beam 5021 are provided with rear bearings, and the wheel shaft of the rotating wheel 5022 is connected with the bearings. One cross beam 5021 is provided with a driving motor 7, and the driving motor 7 is configured as a small stepping motor. The rotating wheel 5022 is located on the side close to the cutting blade 401, and the driving motor 7 is located on the side away from the cutting blade 401. The wheel shaft of the rotating wheel 5022 is connected with the main shaft of the driving motor 7, and the driving motor 7 drives the rotating wheel 5022 to rotate.
[0042] Further, in combination with Figure 2 and Figure 3 The compression belt 5023 is sleeved on the two rotating wheels 5022, and the bottom surface of the compression belt 5023 is in contact with the paperboard 8. The compression belt 5023 has a larger contact area with the paperboard 8 than the rotating wheel 5022, and the compression effect is better. The cutting blade 401 is located at the middle position of the two compression belts 5023, and the lowest part of the cutting blade 401 is aligned with the vertical center line of the compression belt 5023, which ensures that the front and rear paperboards 8 at the cutting position of the cutting blade 401 are pressed by the compression belt 5023, facilitating the lifting of the cutting blade 401.
[0043] It should be noted that the compression belt 5023 is made of rubber material, which is easy to deform and has small pressure on the paperboard 8, and is not easy to produce indentation. In order to avoid slipping between the compression belt 5023 and the rotating wheel 5022, the surface of the rotating wheel 5022 is uniformly provided with a tooth, and the inner wall of the compression belt 5023 is provided with a tooth groove. After the rotating wheel 5022 rotates, the tooth is inserted into the tooth groove, which has a better driving effect on the compression belt 5023.
[0044] Embodiment 2
[0045] Embodiment 2 is further optimized on the basis of the packaging paperboard cutting device of embodiment 1, as follows.
[0046] As shown in Figure 1 and Figure 4 As shown in the top of the device body 1, four fixing pieces 6 are installed for fixing the four corners of the paperboard 8. The fixing piece 6 includes an L-shaped support rod 601 made of metal, and the cross section of the L-shaped support rod 601 is square. The bottom end of the L-shaped support rod 601 is fixedly connected with the device body 1, and the L-shaped support rod 601 is installed with an electric push rod 602, the telescopic end of which is vertically downward, and the bottom end of the electric push rod 602 is installed with a pressing piece 603. The pressing piece 603 has a larger contact area than the bottom end of the electric push rod 602. After the electric push rod 602 is extended, the pressing piece 603 can push the paperboard 8 below to be pressed tightly.
[0047] It should be noted that the pressing piece 603 can be made of a metal sheet, and a rubber layer is fixedly bonded at the bottom of the metal sheet. The rubber layer has a larger friction with the paperboard 8, and the fixing effect is better.
[0048] The working principle of the packaging paperboard cutting device of the utility model is as follows:
[0049] As shown in Figure 5 As shown in the figure, the paperboard 8 to be cut is shown, the thick line shows the cutting line 801 that needs to be cut, the dashed line shows the crease 802, the paperboard 8 outside the cutting line 801 is the excess material, and the paperboard 8 inside the cutting line 801 is the packaging box. As shown in Figure 1 As shown in the figure, before cutting, the workers need to place multiple pieces of paperboard 8 (about 4 or 5 pieces) neatly on the device body 1, and then control the electric push rod 602 to extend, driving the pressing piece 603 to move downward until the pressing piece 603 presses the paperboard 8 below.
[0050] After fixing, start cutting operation, longitudinal moving mechanism 2 and transverse moving mechanism 3 move, cutting mechanism 4 and pressing mechanism 5 move to the predetermined lower knife position. The electric control rotating table of transverse moving mechanism 3 adjusts the angle, the lifting cylinder of transverse moving mechanism 3 drives cutting mechanism 4 and pressing mechanism 5 to move downward, during the process of descending, the pressing belt 5023 of pressing track 502 first contacts the paperboard 8, then the cutting blade 401 contacts the paperboard 8. The cutting blade 401 moves along the preset route, during the process of moving, the rotating cutting blade 401 forms a cutting line 801 on the paperboard 8. Because the driving motor 7 can drive the pressing track 502 to rotate, the pressing track 502 and the cutting blade 401 move synchronously on the paperboard 8. The moving speed and direction of the pressing track 502 and the moving speed and direction of the cutting blade 401 are consistent, which can avoid the paperboard 8 from arching during cutting, and the cutting precision of the paperboard 8 is higher. After cutting is completed, the lifting cylinder of the transverse moving mechanism 3 lifts the cutting blade 401, the pressing track 502 still presses the paperboard 8 under the action of the elastic member 501, which avoids tearing the paperboard 8 or pulling the paperboard 8 upward when the blade is lifted. After lifting the cutting blade 401, the lifting cylinder of the transverse moving mechanism 3 continues to drive the lifting, so that the pressing track 502 also separates from the paperboard 8, and the cutting work of the cutting line 801 is completed.
[0051] In summary, the packaging paperboard cutting device provided by the utility model has the advantages that the packaging paperboard cutting device avoids the arching of the paperboard 8 and has good cutting quality.
[0052] The above detailed description is only a specific embodiment of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
