[0007] The limiting mechanism includes two first limiting plates disposed on the surface of the operating table on one side of the through hole, and the distance between the two first limiting plates is greater than the distance between the two cutting discs.
[0008] Preferably, one end of the operating table is provided with an adjustment groove, and a first bidirectional lead screw is rotatably connected between the two ends of the inner cavity of the adjustment groove via a bearing. Two adjustment blocks are slidably connected in the adjustment groove, and the two adjustment blocks are respectively threaded onto the outer sides of the first bidirectional lead screw. The two adjustment blocks are respectively fixedly connected to the two first limiting plates on one side of the through hole by a connecting plate. One end of the first bidirectional lead screw rotatably passes through the adjustment groove and the operating table and is located on the outside of the operating table. The bottom of the two first limiting plates moves against the surface of the operating table.
[0009] Preferably, a gantry frame is provided above the through hole, and the gantry frame is fixedly connected between the two ends of the operating table. A sliding groove is provided on the top inner side of the gantry frame. A second bidirectional lead screw is rotatably connected between the two ends of the inner cavity of the sliding groove through a bearing. Two sliders are slidably connected in the sliding groove. The two sliders are respectively threaded on both sides of the outer side of the second bidirectional lead screw. A fixing plate is fixedly connected to the bottom of each of the two sliders. Two first drive motors are respectively fixedly connected to the opposite ends of the two fixing plates. One end of the second bidirectional lead screw rotatably passes through the sliding groove and the gantry frame and is located on the outside of the gantry frame.
[0010] Preferably, a collection box is fixedly connected to the bottom of the operating table. The inner cavity of the collection box communicates with the through hole. A discharge port is opened at one end of the collection box. A baffle is provided inside the discharge port.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model combines an operating table, a first limiting plate, a cutting disc, and a first drive motor to place the cardboard board requiring edge cutting on the surface of the operating table between two first limiting plates. Then, the cardboard board is pushed towards one end of the cutting disc. Since the distance between the two first limiting plates is greater than the distance between the two cutting discs, when the cardboard board contacts the cutting disc, the cutting disc driven by the first drive motor can simultaneously cut both sides of the cardboard board at once, thus eliminating the need for manual edge cutting of the cardboard board.

This perfectly adapts to the edge cutting requirements of different specifications of carton boards.
[0017] 3. This utility model combines a second bidirectional lead screw, a slider, a groove, and a fixing plate. By rotating the second lead screw, the slider moves within the groove, allowing adjustment of the distance between the two cutting discs. This facilitates the cutting of the edges of cardboard boxes of different sizes, improving the applicability of the device. Attached Figure Description

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0025] Example 1: A carton edge cutting device, see [link to example]. Figures 1 to 5The system includes: a trimming mechanism, which includes two first drive motors 31 disposed on both sides of the inner cavity of the through hole 11 in the middle of the operating table 1, with the drive ends of the two first drive motors 31 disposed opposite to each other, and each drive end of the two first drive motors 31 being fixedly connected to a cutting disc 3; and a limiting mechanism, which includes two first limiting plates 2 disposed on the surface of the operating table 1 on one side of the through hole 11, with the distance between the two first limiting plates 2 being greater than the distance between the two cutting discs 3.
[0026] During operation, the cardboard board that needs edge trimming is placed on the surface of the operating table 1 between the two first limiting plates 2, and then pushed towards one end of the cutting disc 3. Since the distance between the two first limiting plates 2 is greater than the distance between the two cutting discs 3, when the cardboard board contacts the cutting disc 3, the cutting disc 3 driven by the first drive motor 31 can simultaneously trim both sides of the cardboard board at one time, thus eliminating the need for manual edge trimming of the cardboard board. This not only improves the production efficiency of the cardboard board, but also simplifies the cutting of the cardboard board and reduces the labor intensity of the personnel.
[0027] For details, see Figure 1 One end of the operating table 1 is provided with an adjustment groove 21. The two ends of the inner cavity of the adjustment groove 21 are rotatably connected to a first bidirectional lead screw 24 through bearings. Two adjustment blocks 22 are slidably connected in the adjustment groove 21. The two adjustment blocks 22 are respectively threaded on both sides of the outer side of the first bidirectional lead screw 24. The two adjustment blocks 22 are respectively fixedly connected to the two first limiting plates 2 on one side of the through hole 11 by connecting plates 23. One end of the first bidirectional lead screw 24 rotates through the adjustment groove 21 and the operating table 1 and is placed on the outside of the operating table 1. The bottom of the two first limiting plates 2 moves against the surface of the operating table 1. By rotating the first bidirectional lead screw 24, the adjustment blocks 22 are driven to move smoothly along the adjustment groove 21, thereby synchronously adjusting the precise distance between the two sets of first limiting plates 2 and the cutting disc 3, and thus steplessly adjusting the cutting width. It can perfectly adapt to the edge cutting requirements of different specifications of carton boards. Moreover, the distance adjustment between the first limiting plates 2 and the cutting disc 3 can be completed by rotating the first bidirectional lead screw 24 with one hand, which greatly improves the multi-specification production capacity of the equipment.
[0028] Further, see Figure 2 and Figure 5A gantry frame 4 is provided above the through hole 11, and the gantry frame 4 is fixedly connected between the two ends of the operating table 1. A sliding groove 42 is provided on the top inner side of the gantry frame 4. A second bidirectional lead screw 43 is rotatably connected between the two ends of the inner cavity of the sliding groove 42 through bearings. Two sliders 44 are slidably connected in the sliding groove 42. The two sliders 44 are respectively threaded on the outer sides of the second bidirectional lead screw 43. A fixing plate 41 is fixedly connected to the bottom of each of the two sliders 44. Two first drive motors 31 are respectively fixedly connected to the opposite ends of the two fixing plates 41. One end of the second bidirectional lead screw 43 rotates through the sliding groove 42 and the gantry frame 4 and is placed on the outside of the gantry frame 4. By rotating the second lead screw, the sliders 44 are guided to move in the sliding groove 42, thereby adjusting the distance between the two cutting discs 3. This facilitates the cutting of the two ends of cardboard boards of different sizes, improves the applicability of the device, and only requires one hand to rotate the second lead screw to complete the distance adjustment between the two cutting discs 3, which greatly improves the multi-specification production capacity of the equipment.
[0029] It is worth noting that, see Figure 2 A collection box 5 is fixedly connected to the bottom of the operating table 1. The inner cavity of the collection box 5 is connected to the through hole 11. A discharge port 52 is opened at one end of the collection box 5. A baffle 53 is provided in the discharge port 52. A bolt 54 passes through the outer side of the baffle 53 and is threaded to the surface of the collection box 5. By setting up the collection box 5, the waste material cut from the edge of the cardboard is collected in the collection box 5 through the through hole 11. This not only avoids the accumulation of waste material from affecting the edge cutting of the cardboard, but also avoids the waste material from polluting the working environment. Furthermore, the bolt 54 facilitates the disassembly and assembly of the baffle 53, thereby facilitating the cleaning of the collected waste material.
[0030] It is worth noting that, see Figure 3 and Figure 4 The inner cavity of the collection box 5 is equipped with a filter screen 51. A negative pressure pump 6 is fixedly connected to the operating table 1 on one side of the collection box 5. The suction end of the negative pressure pump 6 is connected to the bottom end of the collection box 5 by a suction pipe 61. The surface of the filter screen 51 is on the same horizontal plane as the bottom end of the inner cavity of the discharge port 52. When collecting waste, the negative pressure pump 6 is started to generate negative pressure in the collection box 5, thereby improving the waste collection effect in conjunction with the filter screen 51.
[0031] It is worth mentioning that, see Figure 3 Each of the two fixed plates 41 is fixedly connected to a second drive motor 7 at one end. The drive end of the second drive motor 7 is fixedly connected to a shredder 71. When the edge of the cardboard is cut, the second drive motor 7 is started to drive the shredder 71 to rotate at high speed, so that the shredder 71 can shred the larger waste material of the cut cardboard and ensure that the cut waste material can be collected in the collection box 5.
[0032] It is worth mentioning that, see Figure 1 Two second limiting plates 26 are provided on the operating table 1 on the side of the through hole 11 away from the first limiting plate 2. A U-shaped connecting frame 25 is fixedly connected between the outer sides of the first limiting plate 2 and the second limiting plate 26 on the same side. The ends of the first limiting plate 2 and the second limiting plate 26 away from the U-shaped connecting frame 25 are on the same horizontal plane. By setting the second limiting plate 26, the carton board after edge cutting can be guided to move, ensuring the quality of the carton board edge cutting. Furthermore, the second limiting plate 26 is made to move synchronously with the adjustment of the first limiting plate 2 through the U-shaped connecting frame 25, which not only ensures the flatness of the cut edge, but also realizes the seamless connection between the cutting and conveying processes, significantly improving the product qualification rate.
