A vertical plate is fixed to the rear side wall of the bottom plate, a workbench is arranged on the top of the bottom plate, and a pulley groove is installed on the top of the bottom plate. The workbench can be moved left and right through a pulley and the pulley groove. After the cardboard is cut, the cut part is taken away. By moving to the right, the right end of the cardboard can always be abutted against the limiting plate, and the cardboard can always be fixed on the workbench. When producing a batch of cardboard of the same length, it is not necessary to mark the length on the cardboard first. After adjustment, it can be directly quantitatively cut, saving time and thus improving work efficiency.

[0004] Although the above patent does not require marking the length on the cardboard first when producing a batch of cardboard of the same length, and can be directly quantitatively cut after adjustment, saving time and thus improving work efficiency, in actual use, it is still necessary to manually adjust the position of the sliding block. When producing cardboard of different lengths, manual adjustment and positioning are required for each case, and the entire operation process is relatively troublesome, time-consuming and laborious, thus reducing the production efficiency to a certain extent.

[0005] Therefore, it is necessary to transform the cardboard quantitative cutting device in the above patent to effectively prevent the problem that when producing cardboard of different lengths, manual adjustment and positioning of the sliding block are required for each case, and the entire operation process is relatively troublesome, time-consuming and laborious, thus reducing the production efficiency to a certain extent.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0016] As Figures 1 to 4 shown, the quantitative cutting mechanism for cardboard in the carton packaging of this embodiment includes a transmission table 1. Inside the transmission table 1, transmission belts 2 are symmetrically and fixedly connected. On the top of the transmission table 1, a gantry 3 is fixedly connected. And between the gantry 3 and the two transmission belts 2, on the top of the gantry 3, a hydraulic telescopic rod 4 is fixedly connected. The output end of the hydraulic telescopic rod 4 is fixedly connected with a lifting plate 5. At the bottom of the lifting plate 5, a cutting knife 6 is fixedly connected. On both sides of the cutting knife 6, pressing plates 7 are symmetrically arranged. On the top of the pressing plates 7, sliding columns 8 are symmetrically fixedly connected with respect to the hydraulic telescopic rod 4. The top of the sliding columns 8 penetrates through the lifting plate 5 and is fixedly connected with a limit disk 9. On the top of the transmission table 1, moving frames 10 are symmetrically fixedly connected. And the moving frames 10 are located on one side of the gantry 3. Inside the moving frames 10, a lead screw 11 is rotatably connected. And the lead screw 11 is driven by a servo motor. A moving frame 12 is threadedly connected to the surface of the lead screw 11. On the top of the moving frame 12, an electric push rod 13 is fixedly connected. At the bottom of the electric push rod 13, a baffle 14 is fixedly connected. And the baffle 14 is arranged in cooperation with the transmission belt 2.

[0017] Refer to Figure 2 , a bearing block 15 is fixedly connected between the two transmission belts 2. And the bearing block 15 is located directly below the pressing plate 7. On the top of the bearing block 15, a cutting opening 16 is opened. And the cutting opening 16 is arranged in cooperation with the cutting knife 6.

[0018] Through the setting of the bearing block 15 in this embodiment, the bearing block 15 can support the pressing plate 7, thereby improving the positioning effect on the cardboard. By using the setting of the cutting opening 16, it can bear the cutting knife 6, avoiding the problem that the cutting knife 6 directly contacts the bearing block 15 and causes its damage.

[0019] Refer to Figure 3 , the number of the sliding columns 8 is eight. And the eight sliding columns 8 are symmetrically arranged in a group of four. A spring 17 is sleeved on the surface of the sliding columns 8. And the spring 17 is located between the pressing plate 7 and the lifting plate 5.

[0020] In this embodiment, through the arrangement of eight sliding columns 8, the two pressing plates 7 can be evenly pressed down to prevent them from tilting. Through the arrangement of the spring 17, a downward thrust can be given to the pressing plate 7, thereby improving the positioning effect of the pressing plate 7 on the cardboard.

[0021] Reference Figure 2 and Figure 3 , the height of the pressing plate 7 is lower than that of the cutting knife 6, and an anti-slip pad is fixedly connected to the bottom of the pressing plate 7.

[0022] In this embodiment, through the setting that the height of the pressing plate 7 is lower than that of the cutting knife 6, it can be ensured that the pressing plate 7 contacts the cardboard first, thereby achieving the effect of automatically positioning the cardboard.

[0023] Reference Figure 2 and Figure 3 , symmetrically fixed inside walls of the gantry 3 are limiting grooves 18, symmetrically fixedly connected to both sides of the lower pressing plate 7 are limiting blocks 19, and the limiting blocks 19 are slidably connected with the limiting grooves 18.

[0024] In this embodiment, through the arrangement of the limiting grooves 18 and the limiting blocks 19, the lifting trajectory of the lifting plate 5 can be restricted, thereby ensuring that the lifting plate 5 can perform vertical lifting.

[0025] Reference Figure 4 , symmetrically fixedly connected to the top of the baffle 14 with respect to the electric push rod 13 are limiting posts 20, a limiting hole 21 is formed in the top of the moving frame 12, and the limiting hole 21 is slidably connected with the limiting posts 20.

[0026] In this embodiment, through the arrangement of the limiting posts 20 and the limiting holes 21, the baffle 14 can perform a linear up-and-down movement, thereby ensuring the stability of the baffle 14 during use.

[0027] When the utility model cuts the cardboard for carton packaging, first, the servo motor is started according to the cutting requirements of the cardboard for carton packaging, and then the lead screw 11 is driven to rotate, so that the moving frame 12 can be moved to a suitable position, and the distance between the baffle 14 and the cutting knife 6 is made consistent with the length required for cutting the cardboard. Then, the electric push rod 13 can be started to drive the baffle 14 to descend so that it fits with the conveyor belt 2. Then, the raw material of the cardboard for carton packaging is placed on the conveyor belt 2 on the other side, and the conveyor belt 2 is started to drive the cardboard for carton packaging to be conveyed, so that the other end of the cardboard for carton packaging is blocked by the baffle 14, and then the conveyor belt 2 can be put on standby. Then, the hydraulic telescopic rod 4 is started to drive the lifting plate 5 to descend, so that the pressing plate 7 can first contact the surface of the raw material of the cardboard for carton packaging and press the spring 17 upward. At this time, the reaction force of the spring 17 can be used to position the raw material of the cardboard for carton packaging by the pressing plate 7. At this time, the bearing block 15 can bear the bottom of the raw material of the cardboard for carton packaging. As the lifting plate 5 continuously descends, the cutting knife 6 can cut the raw material of the cardboard for carton packaging. When the cutting is completed, the hydraulic telescopic rod 4 drives the lifting plate 5 to return to its original position. Then, the electric push rod 13 drives the baffle 14 to move upward. Then, the conveyor belt 2 at the bottom of the baffle 14 can be started to convey the cut cardboard for carton packaging to the designated position. Then, the above steps are repeated to quantitatively cut the raw material of the cardboard for carton packaging, and there is no need for manual operation by workers.
