[0002] Edge trimming is a crucial step in ensuring precise carton dimensions. Accurate trimming ensures that the length, width, height, and opening dimensions of the carton meet design requirements, resulting in smooth and tightly fitting edges and enhanced structural strength. This helps the carton better protect products during transportation and storage, reducing damage and deformation, maximizing material utilization, and minimizing waste. This contributes to lower production costs and aligns with sustainable development principles. Current edge trimming methods typically rely on manual assistance, which is costly and inefficient.
[0003] According to application number 202022247259.X, a cutting device for producing packaging cartons includes a base, a support leg fixedly connected to the lower surface of the base, two mounting seats fixedly connected to the upper surface of the base, a drive mechanism fixedly connected to the outer side of the mounting seats, a pressing mechanism fixedly connected to the upper part of the mounting seats, two mounting rods fixedly connected to the middle of the upper surface of the base, a mounting plate fixedly connected between the mounting rods, an electric telescopic rod mounting seat fixedly connected to the mounting plate, an electric telescopic rod fixedly connected to the lower surface of the electric telescopic rod mounting seat, and a cutting mechanism fixedly connected to the end of the electric telescopic rod away from the electric telescopic rod mounting seat.
[0004] The aforementioned document describes how setting up a drive mechanism can move the packaging cardboard, and setting up a clamping mechanism can ensure that the packaging cardboard does not deviate during automated cutting. However, it lacks the ability to quickly adapt to cutting packaging cardboard of different widths. Utility Model Content
[0005] Therefore, the purpose of this utility model is to provide a packaging carton edge cutting device to solve the technical problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A packaging carton edge cutting device includes a guide rail, a mounting platform at the top of the guide rail, a pushing component at the middle of the guide rail, straightening components on both sides inside the guide rail, two pressure rollers at the middle of the guide rail and at both ends of the bottom of the mounting platform, a translation component at the top of the mounting platform, two sets of frames above the translation component, and a cutting machine below the frames.
[0008] Preferably, the pushing component includes several rectangular grooves passing through the middle of the guide rail, multiple gears rotatably disposed inside the rectangular grooves, a toothed belt connecting all gears in the same rectangular groove, a shaft connecting the gears at the same end in all different rectangular grooves, and a first motor disposed on one side outside the guide rail and whose actuating end is connected to the central shaft of the shaft.
[0009] Preferably, the outer surface of the toothed belt is smooth and includes a plurality of protrusions evenly spaced on the outer surface.
[0010] Preferably, the correction component includes two first telescopic rods disposed on both sides inside the guide rail, a right-angle plate disposed on the actuating end of the first telescopic rod, a pressure sensor disposed on the other side of the right-angle plate, and a distance sensor disposed on the top of the first telescopic rod with its detection end connected to the top of the right-angle plate.
[0011] Preferably, the pressure roller includes sliders at both ends, grooves on both sides of the guide rail, several springs connecting the top of the sliders to the top of the grooves, and multiple sleeves fitted around the center of the outer side of the pressure roller to avoid the running trajectory of the toothed belt.
[0012] Preferably, the translation component includes two slide rails located on the top of the mounting platform, two sets of pulleys located at the bottom of the frame, a threaded tube passing through both sides of the frame, a nut connected to a bidirectional threaded rod in the middle of the threaded tube, and a second motor connected to the central shaft of one end of the bidirectional threaded rod at the actuating end.
[0013] Preferably, the cutting machine includes multiple second telescopic rods connected to the frame at the top, a cutting head at the bottom of the cutting machine, and an arc-shaped groove located in the middle of the guide rail and directly below the cutting head.
[0014] In summary, this technical solution has the following main advantages:
[0015] In this embodiment, by setting a circulating pushing component inside the middle of the guide rail, the packaging cardboard can be pushed into the cutting position. By correcting the position of the packaging cardboard entering the guide rail with the correcting components at both ends during the pushing process, a production line-style packaging cardboard cutting can be achieved, which greatly speeds up the cutting speed of the packaging carton edge.
[0016] Pressure and distance sensors can measure the width of the packaging cardboard after it has been straightened, and then transmit the data to the translation component to cause the two cutting machines to change the cutting position. This enables adaptive adjustment of the cutting width at the cutting position, allowing for the cutting of various widths of packaging cardboard without stopping the machine.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Example
[0025] Please refer to the attached document carefully. Figure 1 , 2As shown in Figures 3 and 5, a packaging carton edge cutting device includes a guide rail 10, a mounting platform 11 at the top of the guide rail 10, a pushing component 12 in the middle of the guide rail 10, straightening components 13 on both sides inside the guide rail 10, two pressure rollers 14 in the middle of the guide rail 10 and located at both ends of the bottom of the mounting platform 11, a translation component 15 at the top of the mounting platform 11, two sets of frames 16 above the translation component 15, and a cutting machine 17 below the frames 16. The pushing component 12 includes several rectangular grooves 121 penetrating the middle of the guide rail 10, and multiple gears 122 rotatably disposed inside the rectangular grooves 121, connecting all the gears in the same rectangular groove 121. The gear 122 has a toothed belt 123, a shaft 124 connecting the same end gear 122 in all different rectangular slots 121, and a first motor 125 located on one side outside the guide rail 10 with its execution end connected to the central shaft of the shaft 124. The outer surface of the toothed belt 123 is smooth and includes a plurality of protrusions 1231 evenly spaced on the outer surface. The straightening component 13 includes two first telescopic rods 131 located on both sides inside the guide rail 10, a right-angle plate 132 located at the execution end of the first telescopic rod 131, a pressure sensor 133 located on the other side of the right-angle plate 132, and a distance sensor 134 located on the top of the first telescopic rod 131 with its detection end connected to the top of the right-angle plate 132.
[0026] As described above, when cutting begins, the first motor 125 starts, driving multiple gears 122 to rotate via shaft 124, which in turn drives the toothed belt 123 to rotate, causing multiple protrusions 1231 to move cyclically. The PLC controls various adjustment elements to perform corresponding operations based on the relative positions of the protrusions 1231. When each 'c' appears from the front end of the guide rail 10, it marks the start of an operating cycle, and the end point is when this protrusion 1231 passes the cutting position of the cutting machine. When the packaging carton is placed at the front end of the guide rail 10 and pushed by the protrusions 1231, the two first telescopic rods 131 start, pushing the right-angle plate 132 closer to each other, causing the packaging cardboard to be in the center of the guide rail 10. When the readings on the pressure sensor 133 are the same, the two first telescopic rods 131 briefly stop and then retract. The distance sensor 134 records the distance reading at the time of pause and sends it to the PLC element.
[0027] Please refer to the attached document carefully. Figure 1 , 2As shown in Figure 4, the pressure roller 14 includes sliders 141 at both ends, grooves 142 on both sides of the guide rail 10, several springs 143 connecting the top of the sliders 141 and the top of the grooves 142, and multiple sleeves 144 sleeved on the outer center of the pressure roller 14 to avoid the running trajectory of the toothed belt 123; the translation component 15 includes two guide rails 151 on the top of the mounting platform 11, two sets of pulleys 152 on the bottom of the frame 16, threaded tubes 153 passing through both sides of the frame 16, a nut connected to a bidirectional threaded rod 154 in the middle of the threaded tube 153, and a second motor 155 connected to the central shaft of one end of the bidirectional threaded rod 154 at the actuation end; the cutting machine 17 includes multiple second telescopic rods 171 connected to the frame 16 at the top, a cutting head 172 at the bottom of the cutting machine 17, and an arc-shaped groove 173 located in the middle of the guide rail 10 and directly below the cutting head 172.
[0028] As described above, several springs 143 press against the slider 141, causing multiple sleeves 144 on the outside of the pressure roller 14 to press against the surface of the packaging cardboard to stabilize it. Under the control of the PLC components, the second motor 155 starts in advance and adjusts the forward and reverse rotation time according to the existing position and distance reading of the distance sensor 134, controlling the bidirectional threaded rod 154 to rotate forward and reverse accordingly. Through the threaded tube 153, it drives the two sets of frames 16 to move in opposite directions on the slide rail 151 to reach the cutting position. When the packaging cardboard reaches the cutting point, multiple second telescopic rods 171 extend, driving the cutting head 172 to descend to the cutting edge. The arc groove 173 provides bottom space for cutting.
[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
