[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown in the embodiment of this utility model, a carton cutting device for carton production includes a feeding platform 1; a cutting mechanism 11 is installed in the middle of the feeding platform 1; a conveyor belt 12 is connected to the side wall of the feeding platform 1; a pair of side plates 13 are fixedly connected to the side wall of the conveyor belt 12; a first motor 14 is installed on the side wall of the side plate 13; a first rotating shaft 15 is fixedly connected to the output end of the first motor 14; a fixing plate 16 is fixedly connected to the end of the side plate 13; a fixing block 17 is fixedly connected to the side wall of the fixing plate 16; a guide frame 18 is fixedly connected to the side wall of the feeding platform 1; the guide... A second motor 19 is fixedly connected to the end of frame 18; a lead screw 110 is fixedly connected to the output end of the second motor 19; the fixing block 17 is threadedly connected to the middle of the lead screw 110; a connecting component is provided on the side wall of the fixing block 17; during operation, when cutting the cardboard, the first motor 14 is started to drive the first rotating shaft 15 and the conveyor belt 12 to rotate, and then the cardboard is placed on the conveyor belt 12 and conveyed to the cutting mechanism 11. Then, the cardboard is cut by the cutting blade of the cutting mechanism 11. At this time, the conveyor belt 12 will drive the cardboard to move to the top of the lower material table 1. When the cardboard is completely removed from the cutting machine... When mechanism 11 passes through, it can complete the cutting of cardboard, and the cut cardboard will be collected on the top of the unloading table 1. When it is necessary to adjust the cutting size of the cardboard, the second motor 19 can be started to reciprocate and drive the lead screw 110 to rotate. At this time, the fixed block 17 will slide back and forth in the guide frame 18. At this time, the fixed block 17 will drive the fixed plate 16 and the conveyor belt 12 to move, so that the conveyor belt 12 and the cutting mechanism 11 can be misaligned, thereby changing the position of the center of the conveyor belt 12 relative to the cutting mechanism 11, thus changing the cutting size of the cardboard. Through the above structure, it is assumed that... The placement of the feed table 1, the cutting mechanism 11, and the conveyor belt 12 facilitates the feeding, cutting, and collection of the cardboard to the cutting mechanism 11 during cutting, reducing the need for workers to manually push the cardboard for cutting, which could lead to hand cuts. At the same time, through the fixing plate 16, the fixing block 17, and the guide frame 18, in conjunction with the second motor 19 and the lead screw 110, the position of the conveyor belt 12 relative to the cutting mechanism 11 can be adjusted to adjust the cutting size of the cardboard, reducing the risk of cuts caused by disassembling and installing the cutting blade when adjusting the cardboard cutting size.

[0025] like Figure 3As shown, a first gear 2 is fixedly connected to the side wall of the first rotating shaft 15; a second rotating shaft 21 is rotatably connected to the middle of the side plate 13; a plurality of rubber wheels 22 are fixedly connected to the middle of the second rotating shaft 21; a second gear 23 is fixedly connected to the side wall of the rubber wheel 22; the first gear 2 and the second gear 23 mesh with each other; during operation, when the first motor 14 drives the first rotating shaft 15 to rotate, the first rotating shaft 15 will drive the first gear 2 to rotate. At this time, the first gear 2 will drive the second gear 23 to rotate in the opposite direction to the second rotating shaft 21 and the rubber wheel 22. When the cardboard is conveyed on the conveyor belt 12, the rubber wheel 22 contacts the top of the cardboard. Under the opposite rotation of the rubber wheel 22 and the conveyor belt 12, the cardboard will be conveyed to the cutting mechanism 11 for cutting. With the above structure, the first gear 2, the second rotating shaft 21 and the rubber wheel 22 are set up, and the second gear 23 is used to fix the cardboard from above and generate a thrust towards the cutting mechanism 11 under the opposite rotation of the rubber wheel 22 and the conveyor belt 12, which can make the cardboard move and be conveyed more stably during cutting.

[0026] like Figure 3 As shown, a cylinder 3 is fixedly connected to the side wall of the side plate 13; a push plate 31 is fixedly connected to the end of the cylinder 3; a plurality of first rollers 32 are rotatably connected to the side wall of the push plate 31; during operation, when the cardboard is conveyed on the surface of the conveyor belt 12, the push plate 31 can be moved to the side of the cardboard by activating the cylinders 3 on both sides. At this time, the push plate 31 can squeeze and limit the cardboard from the side. When the cardboard moves, it will drive the first rollers 32 to rotate, thereby changing the sliding friction between the cardboard and the push plate 31 into rolling friction. Through the above structure, the cylinder 3 and the push plate 31 can clamp and limit the cardboard during conveying, and the first rollers 32 can reduce the friction between the cardboard and the push plate 31 to improve the stability of the cardboard during conveying.

[0027] like Figure 2 As shown, a processing box 4 is fixedly connected to the side wall of the unloading platform 1; a fan 41 is fixedly connected to the side wall of the unloading platform 1; the processing box 4 and the fan 41 are interconnected; a conduit 43 is fixedly connected to the side wall of the processing box 4; an air inlet hood 42 is installed at the end of the conduit 43; during operation, paper scraps and dust are generated when the cutting mechanism 11 cuts the cardboard. At this time, the fan 41 is started to drive the airflow into the air inlet hood 42, which can suck in the generated dust, and then enter the processing box 4 through the conduit 43. At this time, the filter screen installed in the processing box 4 can filter the dust, and then the airflow flows to the fan 41 and is discharged. Through the above structure, the processing box 4, the fan 41 and the air inlet hood 42 are set up to facilitate the absorption and filtration of dust generated during cutting, so as to reduce the situation of dust dispersion causing pollution of the workshop and affecting the health of workers.

[0028] like Figure 1As shown, multiple springs 5 ​​are fixedly connected to the inner wall of the feeding table 1; the ends of the multiple springs 5 ​​are jointly fixedly connected to a baffle 51; during operation, when the cardboard is cut, it will impact the inner wall of the feeding table 1 due to the inertia of its movement. At this time, the cardboard will contact the surface of the baffle 51, and the springs 5 ​​will contract when impacting the baffle 51, thereby buffering the impact of the cardboard. Through the above structure, the springs 5 ​​and the baffle 51 can buffer the impact between the paper and the feeding table 1, so as to reduce the situation where the cardboard is deformed or bent due to the strong impact between the cardboard and the feeding table 1.

[0029] like Figure 4 As shown, the connecting assembly includes a fixed base 6; the fixed base 6 is fixedly connected to the side wall of the fixed block 17; a plurality of second rollers 61 are rotatably connected to the side wall of the fixed base 6; during operation, when the fixed block 17 moves within the guide frame 18, it will drive the fixed base 6 to move within the guide frame 18. At this time, the second rollers 61 contact the guide frame 18 and can rotate as the fixed base 6 moves, thereby converting the sliding friction between the fixed block 17 and the guide frame 18 into rolling friction. Through the above structure, by setting the fixed base 6 and the second rollers 61, the friction between the fixed block 17 and the guide frame 18 can be reduced, so as to reduce the situation where large friction causes large wear between the fixed block 17 and the guide frame 18.

[0030] like Figure 1 and Figure 2 As shown, there is a pair of air intake hoods 42; the pair of air intake hoods 42 are distributed on both sides of the cutting mechanism 11; with the above structure, a pair of air intake hoods 42 are distributed on both sides of the cutting mechanism 11, which can simultaneously draw air from both sides near the cutting position to improve the absorption effect of dust during cutting.

[0031] Working principle: When cutting cardboard, the first motor 14 is started to drive the first rotating shaft 15 and the conveyor belt 12 to rotate. The cardboard is then placed on the conveyor belt 12 and conveyed to the cutting mechanism 11. The cardboard is then cut by the cutting blade of the cutting mechanism 11. At this time, the conveyor belt 12 will drive the cardboard to move to the top of the unloading platform 1. When the cardboard has completely passed the cutting mechanism 11, the cutting work is completed, and the cut cardboard will be collected at the top of the unloading platform 1. When it is necessary to adjust the cutting size of the cardboard, the second motor 19 can be started to reciprocate and drive the lead screw 110 to rotate. At this time, the fixed block 17 will be in the position of the lead screw 110. The guide frame 18 slides back and forth, at which time the fixed block 17 will drive the fixed plate 16 and the conveyor belt 12 to move, so that the conveyor belt 12 and the cutting mechanism 11 can be misaligned, thereby changing the position of the center of the conveyor belt 12 relative to the cutting mechanism 11, thus changing the cutting size of the cardboard. When the first motor 14 drives the first rotating shaft 15 to rotate, the first rotating shaft 15 will drive the first gear 2 to rotate. At this time, the first gear 2 will drive the second gear 23 to rotate in the opposite direction to the second rotating shaft 21 and the rubber wheel 22. When the cardboard is conveyed on the conveyor belt 12, the rubber wheel 22 contacts the top of the cardboard, and through the rubber wheel 22 and the conveyor belt 12 When rotating in the reverse direction, the cardboard is conveyed to the cutting mechanism 11 for cutting. When the cardboard is conveyed on the surface of the conveyor belt 12, the cylinders 3 on both sides can be activated to stretch and move the push plate 31 to the side of the cardboard. At this time, the push plate 31 can squeeze and limit the cardboard from the side. When the cardboard moves, it will drive the first roller 32 to rotate, thereby changing the sliding friction between the cardboard and the push plate 31 into rolling friction. When the cutting mechanism 11 cuts the cardboard, paper scraps and dust will be generated. At this time, the fan 41 is activated to drive the airflow into the air inlet hood 42, which can suck in the generated dust and then enter the processing box 4 through the duct 43. At this time, the filter screen installed in the processing box 4 can filter the dust, and then the airflow flows to the fan 41 for discharge. When the cardboard is cut, it will hit the inner wall of the lower material table 1 due to the inertia of the movement. At this time, the cardboard will contact the surface of the baffle 51, and the spring 5 will contract when it impacts the baffle 51, thereby buffering the impact of the cardboard. When the fixed block 17 moves in the guide frame 18, it will drive the fixed seat 6 to move in the guide frame 18. At this time, the second roller 61 contacts the guide frame 18 and can rotate when it moves with the fixed seat 6, thereby changing the sliding friction between the fixed block 17 and the guide frame 18 into rolling friction.
