[0036] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] 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.

[0038] As attached Figure 2 and Figure 3 As shown, two supports 1 are arranged symmetrically, with a cutting table 12 disposed between the two supports 1. A conveyor belt 13 for conveying cardboard 3 is disposed on the cutting table 12, and a crossbeam 11 is disposed above the cutting table 12. The ends of the crossbeam 11 are disposed on the two supports 1 for forward and backward movement. A cutting wheel 2 is disposed on the crossbeam 11 for lifting and moving left and right. Specifically, the cutting wheel 2 is mounted on a lifting frame 21, which is mounted on a transverse frame 22 for lifting and lowering, while the transverse frame 22 is mounted on the crossbeam 11 for left and right movement. The cutting wheel 2 is driven to rotate by a cutting motor 23 disposed on the lifting frame 21. During use, the crossbeam 11, transverse frame 22, and lifting frame 21 are moved. During this process, the cutting motor 23 drives the cutting wheel 2 to rotate and cut the cardboard 3 on the conveyor belt 13, forming a cardboard 31. The lifting frame 21 is provided with a lifting screw, and the traverse frame 22 is threadedly connected to the lifting screw to drive the lifting frame 21 up and down. The crossbeam 11 and the support 1 are both provided with racks. The traverse frame 22 and the crossbeam 11 are both provided with gear motors for driving the rotation of gears. The gears mesh with the racks to drive the traverse frame 22 and the crossbeam 11. The movement of the traverse frame 22 and the crossbeam 11 is guided and limited by slide rails and sliders to ensure that the traverse frame 22 and the crossbeam 11 can move smoothly.

[0039] It is worth mentioning that, as Figure 2As shown, a fixed platform 14 is provided at the rear end of the cutting table 12. This fixed platform 14 has a vacuum chamber within it, and a plurality of suction holes 16 are formed on the surface of the fixed platform 14. When cutting the cardboard 3, the vacuum chamber is evacuated, so that the suction holes 16 on the fixed platform 14 vacuum-absorb and fix the cardboard 3, preventing the cardboard 3 from shifting during the cutting process, thereby ensuring cutting quality. Furthermore, a stop plate 17 is provided at the end of the fixed platform 14 facing away from the cutting table 12. This stop plate 17 is positioned above the fixed platform 14 and raised and lowered. The stop plate 17 is driven by stop cylinders located on both sides of the fixed platform 14. During use, the stop plate 17 is lowered, and the cardboard 3 is moved onto the fixed platform 14 under conveyance until one end of the cardboard 3 abuts the stop plate 17. The cardboard 3 is then vacuum-absorbed and fixed for cutting. At this time, the stop plate 17 acts as a stop and limiter for the cardboard 3, ensuring the cutting size of the cardboard 3.

[0040] 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. The two ends of the longitudinal roller 51 are respectively arranged on the two longitudinal lifting blocks 52 through bearings for rotation. The longitudinal roller 51 is driven by an indentation motor 57 provided on the longitudinal lifting block 52. The two longitudinal lifting blocks 52 are respectively arranged in the two longitudinal lifting frames 53 for lifting and lowering. The longitudinal lifting block 52 is driven by a lifting cylinder 58 provided 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. 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 closer 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 action of 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.

[0041] Details are as attached Figure 5 and Figure 6As shown, the longitudinal indentation wheel 54 includes an indentation main plate 541 and an indentation ring 543 arranged on the outside of the indentation main plate 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 indentation main plate 541 is arranged in the accommodating space and moves left and right. After the connecting arm 542 passes through the longitudinal notch 55, the indentation ring 543 is sleeved on the outside of the longitudinal roller 51 and moves left and right. Among them, four indentation screws 56 are provided in the longitudinal roller 51, and each indentation screw 56 can rotate independently. The indentation main plate 541 of the longitudinal indentation wheel 54 41 is provided with four through holes 544, and each longitudinal creasing wheel 54 has only one through hole 544 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 screw 56 is rotated, only the longitudinal creasing wheel 54 corresponding to the creasing screw 56 will be located on the longitudinal roller 51 and move left and right to adjust its position to adapt to cardboards 31 of different sizes.

[0042] As attached Figure 1 、 Figure 4 and Figure 8 As shown, the rear end of the transition platform 4 is equipped with a guardrail 42, and the upper surface of the transition platform 4 is equipped with a push plate 43. This push plate 43 moves along the length of the guardrail 42 and is driven by a screw mechanism. Specifically, the guardrail 42 is provided with a push screw, and the push plate 43 is threadedly connected to the push screw, driving the push plate 43 to move left and right. After the cardboard 31 completes the longitudinal indentation and is moved to the transition platform 4, the cardboard 31 is manually pressed against the surface of the guardrail 42, and then the push plate 43 pushes the cardboard 31 to the right. A cutting station 6 is located to the right of the transition platform 4. The end of the cutting station 6 near the transition platform 4 is equipped with a transverse indentation mechanism 7. This transverse indentation mechanism 7 has the same structure as the longitudinal indentation mechanism 5 and is used to perform transverse indentations on the cardboard 31.

[0043] 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 provided on the gantry 61, and the two cutting mechanisms 8 are arranged in the gantry 61 and move back and forth. Specifically, two gantry sliders 62 and two gantry screw rods 64 are provided in the gantry 61, and the two gantry screw rods 64 are respectively used to drive the two gantry sliders 62 to move back and forth 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 back and forth and adjust its position to adapt to cardboards 31 of different sizes.

[0044] 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 connector 88, a first knife die 89 and a second knife die 810. The back plate 81 is mounted on the gantry slider 62, and a bearing slide 811 is provided on the back plate 81. An upper slider 82 is provided on the upper side of the bearing slide 811. The upper slider 82 is provided on the front 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 of the back plate 81 and is lifted and lowered. The lower slider 83 is provided with a steering mechanism on the front side. Slider 84, the steering slider 84 is located on the lower slider 83 and moves back and forth. 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. 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 laterally indented by the transverse indentation mechanism 7 and extends from the bottom of the transverse indentation mechanism 7, the upper slider 82 is driven forward and backward by the upper cylinder 821. The upper slider 82 drives the steering slider 84 and the lower slider 83 to move through the connecting rod 85. During this process, the bearing groove 811 guides and limits the bearing 87, causing the steering member 86 located on the steering slider 84 to rotate, so that the first cutting die 89 and the second cutting die 810 are alternately arranged downward to perform cutting. At least one of the first cutting die 89 and the second cutting die 810 can be extended and retracted 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 are all 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.

[0045] Details are as attached Figures 11 to 14As shown, during the rotation of the steering member 86, the second cutting die 810 faces downward while the steering slider 84 moves vertically downward along the bearing slot 811, cutting the ends of the longitudinal indentations on the paperboard 31. Therefore, the first cutting die 89 is retracted and located on the cutting die connector 88. This first cutting die 89 is driven by a cutting die cylinder 891 located on the cutting die connector 88. When the steering member 86 rotates, causing the first cutting die 89 to face downward and the steering slider 84 to move horizontally along the bearing slot 811, the cutting die cylinder 891 drives the first cutting die 89 downward, cutting the edges and corners of the paperboard 31. Furthermore, during the cutting process of the paperboard 31, the transverse indentation mechanism 7 can pause its rotation to keep the paperboard 31 stationary, facilitating cutting. Alternatively, the gantry 61 can drive the cutting mechanism 8 to move synchronously with the paperboard 31, maintaining relative stillness and facilitating cutting. After cutting, the gantry 61 resets the cutting mechanism 8 to prepare for the next cut. At the same time, both ends of the gantry 61 are provided with a clearance opening 63, which makes room for the upper cylinder 821 to avoid collision.

[0046] In summary, when the present invention is in use, the cardboard 3 is conveyed via the conveyor belt 13, the cardboard 3 is fixed by vacuum suction using the fixed platform 14, and then the crossbeam 11, the transverse frame 22, and the lifting frame 21 are moved. During this process, the cutting wheel 2 rotates and cuts the cardboard 3 on the conveyor belt 13, forming a cardboard 31. The cardboard 31 then approaches the longitudinal roller 51, and the longitudinal roller 51 performs a longitudinal indentation on the cardboard 31. After the cardboard 31 moves to the transition platform 4, the longitudinally indented cardboard 31 is placed against the surface of the fence 42, and then the push plate 43 pushes the cardboard 31 to the right to the transverse indentation mechanism 7, and the transverse indentation mechanism 7 performs a transverse indentation on the cardboard 31. During 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 downward to cut the corners on one side of the cardboard 31 and the two ends of the longitudinal indentation on the cardboard 31, thereby completing 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, the various screws in the present invention are driven to rotate by corresponding screw motors, and guide light rods are provided for guidance and limiting. At the same time, the movement of the components such as the crossbeam 11, the transverse frame 22, the lifting frame 21, the cutting wheel 2, and the upper slider 82 in the present invention are all controlled by the control box 18 provided on the support 1. Specifically, the screw motor, the cutting motor 23, the gear motor, the upper cylinder 821 and other components are all electrically connected to the controller in the control box 18, and the controller is used to control the operation of the device.

[0047] A processing flow of a device for making food packaging cartons is characterized by the following steps:

[0048] In the first step, the cardboard 3 is conveyed by the conveyor belt 13;

[0049] In the second step, when the part of the cardboard 3 to be cut is moved to the fixing table 14, the vacuum chamber is evacuated so that the adsorption holes 16 on the fixing table 14 adsorb and fix the cardboard 3 by vacuum, thereby preventing the cardboard 3 from shifting during the cutting process and ensuring the cutting quality;

[0050] In the third step, the crossbeam 11, the transverse frame 22 and the lifting frame 21 are moved. During this process, the cutting wheel 2 rotates and cuts the paperboard 3 on the conveyor belt 13 to form a paperboard 31;

[0051] Step 4: stop vacuuming and loosen the cardboard 31 and the paperboard 3;

[0052] In the fifth step, the cardboard 31 continues to move under the push of the paperboard 3 and the conveyor belt 13, approaching the longitudinal roller 51. During this 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.

[0053] Step 6: When the paperboard 31 contacts the longitudinal creasing wheel 54, the longitudinal creasing wheel 54 rolls to perform longitudinal creasing on the paperboard 31. At the same time, the paperboard 31 is driven to move under the action of the friction between the longitudinal creasing wheel 54 and the paperboard 31.

[0054] Step 7: After the longitudinal indentation of the cardboard 31 is completed and the cardboard 31 is moved to the transition table 4, the cardboard 31 after the longitudinal indentation is manually pressed against the surface of the fence 42;

[0055] In the eighth step, the paperboard 31 is pushed to the right by the pushing plate 43 to move to the transverse indentation mechanism 7, and the transverse indentation mechanism 7 performs transverse indentation on the paperboard 31;

[0056] In the ninth step, when the cardboard 31 extends from the bottom of the transverse indentation mechanism 7, the upper slider 82 moves forward and backward, and the upper slider 82 drives the steering slider 84 and the lower slider 83 to move through the connecting rod 85. During this process, the bearing groove 811 guides and limits the bearing 87, causing the steering member 86 on the steering slider 84 to rotate, so that the first cutting die 89 and the second cutting die 810 are alternately facing downward. After the first cutting die 89 or the second cutting die 810 moves downward, it cuts the corners on one side of the cardboard 31 and the two ends of the longitudinal indentation on the cardboard 31, completing the production of the cardboard 31.

[0057] In the tenth step, the cardboard 31 is folded along the longitudinal and transverse indentations to form a packaging carton and fixed. This has a compact structure and improves production efficiency and accuracy.

[0058] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.

6. The processing flow of the equipment for making food packaging cartons according to claim 1 is characterized in that: Follow these steps: The first step is to transport the cardboard through the conveyor belt; In the second step, when the part of the paper to be cut is moved to the fixing table, the fixing table fixes the paper by vacuum suction; The third step is to move the crossbeam, the transverse frame and the lifting frame. During this process, the cutting wheel rotates and cuts the paper on the conveyor belt to form cardboard. Step 4: Stop vacuuming and loosen the cardboard and paper; In the fifth step, the cardboard continues to move under the push of the paper skin and the conveyor belt, approaching the longitudinal roller. During this process, the longitudinal creasing wheel is located on the longitudinal roller and moves into place. At the same time, the longitudinal roller drives the longitudinal creasing wheel to roll. Step 6: When the cardboard contacts the longitudinal creasing wheel, the longitudinal creasing wheel rolls to perform longitudinal creasing on the cardboard, and the cardboard is driven to move under the action of the friction between the longitudinal creasing wheel and the cardboard; Step 7: After the cardboard has been longitudinally indented and moved to the transition table, the cardboard with longitudinal indentation is placed against the surface of the fence. In the eighth step, the paperboard is pushed to the right by the pushing plate to move to the transverse indentation mechanism, and the transverse indentation mechanism is used to perform transverse indentation on the paperboard; In the ninth step, when the cardboard is extended from the bottom of the transverse indentation mechanism, the upper slider moves forward and backward, and the upper slider drives the steering slider and the lower slider to move through the connecting rod. During this process, the bearing groove guides and limits the bearing, causing the steering member on the steering slider to rotate, so that the first cutting die and the second cutting die face downward alternately. After the first cutting die or the second cutting die moves downward, it cuts the corners on one side of the cardboard and the two ends of the longitudinal indentation on the cardboard, completing the production of the cardboard; The tenth step is to fold the cardboard along the longitudinal and transverse indentations into a packaging box and fix it.
