[0029] As attached Figure 1 As shown, a device for making a food packaging carton includes a support 1, a cutting wheel 2, a transition table 4, a longitudinal creasing mechanism 5, a cutting table 6, a transverse creasing mechanism 7 and a cutting mechanism 8.

[0030] As attached Figure 2 and Figure 3 As shown, two supports 1 are arranged symmetrically, and a cutting table 12 is provided between the two supports 1. A conveyor belt 13 for conveying paperboard 3 is provided on the cutting table 12, and a crossbeam 11 is provided above the cutting table 12. The two ends of the crossbeam 11 are respectively provided on the two supports 1 to move forward and backward. A cutting wheel 2 that can be raised and lowered and moved left and right is provided on the crossbeam 11. Specifically, the cutting wheel 2 is installed on a lifting frame 21. The lifting frame 21 is provided on a transverse frame 22 to be raised and lowered, and the transverse frame 22 is provided on the crossbeam 11 to be moved left and right. The cutting wheel 2 is driven to rotate by a cutting motor 23 provided on the lifting frame 21. When in use, the crossbeam 11, the transverse frame 22 and the lifting frame 21 are moved. During the process, the cutting motor 23 drives the cutting wheel 2 to rotate and cut the paperboard 3 on the conveyor belt 13 to form a paperboard 31. Among them, the lifting frame 21 is provided with a lifting screw rod, and the traverse frame 22 is threadedly connected with the lifting screw rod to drive the lifting frame 21 to rise and fall, and the cross beam 11 and the support 1 are both provided with racks, and the traverse frame 22 and the cross beam 11 are both provided with gear motors for driving the gear to rotate, and the gear and the rack are meshed to drive the traverse frame 22 and the cross beam 11 to move. In addition, the movement of the traverse frame 22 and the cross beam 11 is guided and limited by the slide rail and the slider to ensure that the traverse frame 22 and the cross beam 11 can move smoothly.

[0031] It is worth mentioning that Figure 2As shown, a fixed platform 14 is provided at the rear end of the cutting platform 12, and a vacuum chamber is provided in the fixed platform 14, and a plurality of adsorption holes 16 are penetrated on the surface of the fixed platform 14. When cutting the cardboard 3, the vacuum chamber is evacuated so that the adsorption holes 16 on the fixed platform 14 are vacuum adsorbed and fixed to the cardboard 3, so as to prevent the cardboard 3 from being offset during the cutting process, thereby ensuring the cutting quality. In addition, a stop plate 17 is provided at one end of the fixed platform 14 facing away from the cutting platform 12, and the stop plate 17 is located above the fixed platform 14 and is lifted and lowered, and the stop plate 17 is driven by the stop cylinders provided on both sides of the fixed platform 14. When in use, the stop plate 17 is lowered, and the cardboard 3 is moved to the fixed platform 14 under the conveyance until one end of the cardboard 3 is against the stop plate 17, and then the cardboard 3 is vacuum adsorbed and fixed for cutting, and at this time, the stop plate 17 plays a role of blocking and limiting the cardboard 3, so as to ensure the cutting size of the cardboard 3.

[0032] As attached Figure 4 , Figure 5 and Figure 7 As shown, a transition platform 4 is provided at the rear end of the fixed platform 14, and a longitudinal indentation mechanism 5 is provided at the front end of the transition platform 4. The longitudinal indentation mechanism 5 includes a longitudinal roller 51, a longitudinal lifting block 52, a longitudinal lifting frame 53 and a longitudinal indentation wheel 54. Longitudinal lifting blocks 52 and longitudinal lifting frames 53 are provided at both ends of the longitudinal roller 51. Both ends of the longitudinal roller 51 are respectively arranged on two longitudinal lifting blocks 52 through bearings for rotation. The longitudinal roller 51 is driven by an indentation motor 57 arranged on the longitudinal lifting block 52. The two longitudinal lifting blocks 52 are respectively arranged in two longitudinal lifting frames 53 for lifting and lowering. The longitudinal lifting blocks 52 are driven by a lifting cylinder 58 arranged on the longitudinal lifting frame 53, and the two longitudinal lifting frames 53 are respectively arranged on both sides of the front end of the transition platform 4. Four longitudinal indentation wheels 54 are provided on the longitudinal roller 51, and the four longitudinal indentation wheels 54 can be individually located on the longitudinal roller 51 and move left and right. After the cardboard 3 is cut to form the paperboard 31, the cardboard 3 is pushed by the conveyor belt 13 to continue to move the cardboard 31 close to the longitudinal roller 51. During the process, the longitudinal creasing wheel 54 is located on the longitudinal roller 51 and moves into position. At the same time, the longitudinal roller 51 drives the longitudinal creasing wheel 54 to roll until the cardboard 31 contacts the longitudinal creasing wheel 54. The longitudinal creasing wheel 54 rolls to perform longitudinal creasing on the cardboard 31, and the cardboard 31 is driven to move under the friction between the longitudinal creasing wheel 54. During the process, since the rotation speed of the longitudinal roller 51 and the longitudinal creasing wheel 54 is greater than the rotation speed of the conveyor belt 13, the cardboard 31 can be separated from the cardboard 3, which is convenient for the subsequent blocking and fixing of the cardboard 3.

[0033] Details are as attached Figure 5 and Figure 6As shown, the longitudinal creasing wheel 54 includes a creasing main board 541 and a creasing ring 543 arranged on the outside of the creasing main board 541 through a connecting arm 542. The interior of the longitudinal roller 51 is hollow to form an accommodating space, and a longitudinal notch 55 is provided on the side of the longitudinal roller 51. The creasing main board 541 is arranged in the accommodating space and moves left and right. After the connecting arm 542 passes through the longitudinal notch 55, the creasing ring 543 is sleeved on the outside of the longitudinal roller 51 and moves left and right. Among them, four creasing lead screws 56 are arranged in the longitudinal roller 51, and each creasing lead screw 56 can rotate independently. The creasing main board 541 of the longitudinal creasing wheel 54 Four through holes 544 are provided on 41, and only one through hole 544 on each longitudinal creasing wheel 54 is threadedly connected to the creasing screw 56, and the other through holes 544 are threadedly connected to other creasing screws 56 through threaded sleeves, and the threaded sleeves are installed in the through holes 544 through bearings for rotation, and the threaded sleeves play a guiding role. At the same time, the longitudinal creasing wheels 54 correspond to the creasing screws 56 one by one, so that when the creasing screws 56 are rotated, only the longitudinal creasing wheels 54 corresponding to the creasing screws 56 will be located on the longitudinal roller 51 and move left and right to adjust the position to adapt to cardboards 31 of different sizes.

[0034] As attached Figure 1 , Figure 4 and Figure 8 As shown, a fence 42 is provided at the rear end of the transition platform 4, and a push plate 43 is provided on the upper surface of the transition platform 4. The push plate 43 moves along the length direction of the fence 42. The push plate 43 is driven by a screw mechanism. Specifically, a push screw is provided on the fence 42. The push plate 43 is threadedly connected with the push screw to drive the push plate 43 to move left and right. When the cardboard 31 is moved to the transition platform 4 after the longitudinal indentation, the cardboard 31 after the longitudinal indentation is manually pressed against the surface of the fence 42, and then the cardboard 31 is pushed to the right by the push plate 43. A cutting platform 6 is provided on the right side of the transition platform 4. The end of the cutting platform 6 close to the transition platform 4 is provided with a transverse indentation mechanism 7. The transverse indentation mechanism 7 has the same structure as the longitudinal indentation mechanism 5. The transverse indentation mechanism 7 is used to perform transverse indentation on the cardboard 31.

[0035] In addition, as attached Figures 8 to 10As shown, a gantry 61 is provided at one end of the cutting table 6 facing away from the transition table 4, and two cutting mechanisms 8 are arranged on the gantry 61, and the two cutting mechanisms 8 are arranged in the gantry 61 and move forward and backward. Specifically, two gantry sliders 62 and two gantry screw rods 64 are arranged in the gantry 61, and the two gantry screw rods 64 are respectively used to drive the two gantry sliders 62 to move forward and backward separately. Specifically, only one side of the gantry slider 62 is threadedly connected to one of the gantry screw rods 64, and the other side of the gantry slider 62 is threadedly connected to the other gantry screw rod 64 through a threaded sleeve, and the threaded sleeve is installed in the through hole 544 through a bearing for rotation, and the threaded sleeve plays a guiding role. At the same time, the gantry screw rod 64 corresponds to the gantry slider 62 one by one, so that when the gantry screw rod 64 is rotated, only the gantry slider 62 corresponding to the gantry screw rod 64 will drive the cutting mechanism 8 to move forward and backward, and adjust the position to adapt to cardboards 31 of different sizes.

[0036] Among them, as attached Figures 9 to 14As shown, the cutting mechanism 8 includes a back plate 81, an upper slider 82, a lower slider 83, a steering slider 84, a connecting rod 85, a steering member 86, a bearing 87, a knife die connecting member 88, a first knife die 89 and a second knife die 810. The back plate 81 is installed on the gantry slider 62, and a bearing slide groove 811 is provided on the back plate 81. An upper slider 82 is provided on the upper side of the bearing slide groove 811. The upper slider 82 is provided on the front side of the back plate 81 and moves back and forth. The upper slider 82 is driven by an upper cylinder 821 provided on the back plate 81. A lower slider 83 is provided on the lower side of the upper slider 82. The lower slider 83 is provided on the front side of the back plate 81 for lifting and lowering, and a steering member is provided on the front side of the lower slider 83. Slider 84, the steering slider 84 is located on the lower slider 83 and moves forward and backward. The steering slider 84 and the upper slider 82 are connected by a connecting rod 85. The two ends of the connecting rod 85 are respectively hinged to the steering slider 84 and the upper slider 82. A steering member 86 is provided on the steering slider 84. The steering member 86 is set to avoid the lower slider 83, and the steering member 86 can be rotatably passed through the steering slider 84 and two bearings 87 are installed. The two bearings 87 move along the bearing groove 811, and the end of the steering member 86 facing away from the bearing 87 is provided with a knife die connecting member 88, and the adjacent two side surfaces of the knife die connecting member 88 are respectively provided with a first knife die 89 and a second knife die 810. When the cardboard 31 is horizontally indented by the horizontal indentation mechanism 7 and extends from the bottom of the horizontal indentation mechanism 7, the upper slider 82 is driven to move forward and backward by the upper cylinder 821, and the upper slider 82 drives the steering slider 84 and the lower slider 83 to move through the connecting rod 85. During the process, the bearing slide groove 811 guides and limits the bearing 87, so that the steering member 86 on the steering slider 84 rotates, so that the first cutting die 89 and the second cutting die 810 are alternately set downward for cutting, and at least one of the first cutting die 89 and the second cutting die 810 can be extended relative to the cutting die connecting member 88. At the same time, the movement of the upper slider 82, the lower slider 83 and the steering slider 84 is guided and limited by the slide rails and sliders, ensuring that the upper slider 82, the lower slider 83 and the steering slider 84 can move smoothly.

[0037] Details are as attached Figures 11 to 14As shown, in the present invention, during the rotation of the steering member 86, the second cutting die 810 is downward while the steering slider 84 moves vertically downward along the bearing slot 811 to cut the two ends of the longitudinal indentation on the paperboard 31. Therefore, the present invention is that the first cutting die 89 is located on the cutting die connecting member 88 and is retracted, and the first cutting die 89 is driven by a cutting die cylinder 891 provided on the cutting die connecting member 88. When the steering member 86 rotates, so that the first cutting die 89 is downward, and the steering slider 84 moves horizontally along the bearing slot 811, the first cutting die 89 is driven downward by the cutting die cylinder 891 to cut the corners of the paperboard 31. In addition, during the process of cutting the paperboard 31, the horizontal indentation mechanism 7 can be stopped from rolling to keep the paperboard 31 still for convenient cutting, or the gantry 61 can drive the cutting mechanism 8 to move synchronously with the paperboard 31 to keep relatively still for convenient cutting. After cutting, the gantry 61 drives the cutting mechanism 8 to reset to prepare for the next cutting. At the same time, both ends of the gantry 61 are provided with a clearance opening 63, and the clearance opening 63 makes room for the upper cylinder 821 to avoid collision.

After the cardboard 31 moves to the transition platform 4, the longitudinally indented cardboard 31 is abutted against the surface of the fence 42, and then the cardboard 31 is pushed to the right by the push plate 43 to move to the transverse indentation mechanism 7, and the transverse indentation mechanism 7 performs transverse indentation on the cardboard 31. In the process of the cardboard 31 extending from the bottom of the transverse indentation mechanism 7, the first cutting die 89 or the second cutting die 810 on the cutting mechanism 8 moves down to cut the corners on one side of the cardboard 31 and the two ends of the longitudinal indentation on the cardboard 31 to complete the production of the cardboard 31. Finally, the cardboard 31 is folded into a packaging carton along the longitudinal indentation and the transverse indentation and fixed. The structure is compact and the production efficiency and accuracy are improved. Among them, various screws in the present invention are driven to rotate by corresponding screw motors, and guide light rods are set for guidance and limiting. At the same time, the movement of the crossbeam 11, the transverse frame 22, the lifting frame 21, the cutting wheel 2, the upper slider 82 and other components in the present invention are all controlled by the control box 18 arranged on the support 1.
