Technical Field
[0001] This invention relates to the field of cardboard box processing technology, and in particular to a fully automatic cardboard box folding and forming equipment. Background Technology
[0002] Cardboard box manufacturing is the process of producing packaging boxes from corrugated cardboard through printing, die-cutting, slotting, and gluing. Cardboard boxes are widely used in industries such as logistics, e-commerce, food, and home appliances. Subsequent stages of cardboard box manufacturing include precisely folding the printed, die-cut, and creased corrugated cardboard along pre-set crease lines, and then forming the complete box body through gluing (applying adhesive) or stapling.
[0003] Currently, the folding and forming process of cardboard boxes often relies on manual positioning, manual folding, or semi-automatic operation. This is not only labor-intensive and inefficient, but also easily affected by worker fatigue or skill level, resulting in poor product quality consistency. The lack of rigid support inside the formed cardboard makes it prone to deformation and collapse, leading to indistinct edges and poor geometric accuracy. Traditional forming equipment typically uses a one-machine-one-model approach; when the length and width specifications of the cardboard box change, a significant amount of time needs to be spent manually changing the mold and performing complex mechanical adjustments and installations. Therefore, this invention proposes a fully automatic folding and forming equipment for cardboard box processing to solve the problems mentioned in the background. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic folding and forming equipment for cardboard box processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic cardboard box folding and forming device includes a conveying device. A forming frame is fixedly installed at the upper center of the conveying device, and a column is fixedly installed at the lower part of the forming frame. Side seats 1 are provided on both the left and right sides of the lower part of the column, and side seats 2 are provided at the front and rear of the lower part of the forming frame. A rack seat is fixed to the inner side of each of the side seats 1 and 2. The rack seats slide inward and outward within the central column. Corner seats corresponding to side seats 1 and 2 are provided at the four corners of the lower part of the column. A rotating mechanism is provided between adjacent rack seats. A spur gear connected to the column meshes with the rack seats on both sides. The conveying device is provided with two slide blocks 1. Each slide block 1 has a slide block 2 that slides inward and outward at both ends. A rotating shaft is rotatably connected to the lower part of each slide block. Each end of the rotating shaft is fixed with a screw rod 2. The two screw rods 2 are respectively threaded to the corresponding upper slide block 2. Support bars 1 are rotatably connected to the two outer ends of each slide block 1, and support bars 2 are rotatably connected to the outer ends of each slide block 2. The cardboard box is folded into shape by the support bars 1 and 2.
[0006] Preferably, the corner seat is provided with a sliding groove corresponding to side seat one and side seat two, and side seat one and side seat two slide left and right between the two corner seats.
[0007] Preferably, the conveying device includes a conveying seat, two conveying rollers and a conveying belt, and a driving device connected to one of the conveying rollers is installed on the conveying seat, and both of the slides slide left and right within the conveying seat.
[0008] Preferably, the conveying device has two screws rotatably connected inside the conveying seat, the two screws are fixedly connected to each other, and the two screws are threadedly connected to the two slides respectively.
[0009] Preferably, each spur gear is fixed with a bevel gear one on its upper side, and a corresponding bevel gear two is provided on the upper side of the bevel gear one. Two screws three are rotatably connected to the upper part of the column.
[0010] Preferably, a synchronous pulley is fixed to the outer end of the screw and the outer side of the bevel gear, and a corresponding synchronous belt is sleeved on the outside of the two synchronous pulleys on the same side.
[0011] Preferably, the upper part of the column is provided with two sliding blocks corresponding to the screw three, the two sliding blocks are respectively threaded to the two screw three, and the sliding blocks are slidably connected inside the column.
[0012] Preferably, a motor is fixedly installed on the slide block 2, and the output shaft of the motor is fixedly connected to the support bar 2 on the slide block 2.
[0013] Preferably, both ends of the slide block are provided with rectangular groove rods, which slide inward and outward on the slide block. The rectangular groove rods and the support bar are located on the same rotation axis, and a rectangular through groove for the rectangular groove rod is opened at the center of the transition part of the support bar.
[0014] Preferably, the rectangular groove rod is rotatably connected to the slide block two on the corresponding side, a bevel gear three is fixed to the outer end of the rectangular groove rod, and another bevel gear three that meshes with the bevel gear three is fixed to the outer side of the transition part of the support bar two.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention has high versatility and can adapt to the production needs of cartons with different length and width specifications. Through the twin screw drive and synchronous belt transmission mechanism, the operator can easily adjust the length and width of the internal support frame. This adjustment is not limited to the support structure. The bottom folding support bar assembly can also be adjusted synchronously through the linkage screw and slide system. The all-round adjustable size design breaks the limitation of the single specification of traditional equipment. 2. The present invention adopts a cuboid internal support structure composed of side seats, corner seats and rack seats. During the folding process, this structure acts as a rigid inner mold, providing a solid support for the folding of corrugated cardboard. The design effectively prevents the cardboard from deforming or collapsing when folded under force, ensuring the geometric accuracy and sharpness of the carton forming, and significantly improving the appearance quality and structural strength of the finished carton. 3. This invention integrates conveying, positioning, adjustment, and folding processes. After the corrugated cardboard enters the workstation via the conveying equipment, the equipment automatically completes the transformation from a two-dimensional to a three-dimensional shape. The motor at the bottom drives the support bars to rotate 90 degrees, which, together with the internal support structure above, instantly completes the folding action, replacing tedious manual operation. This not only greatly improves production efficiency but also reduces labor intensity, while ensuring product consistency.
[0016] In summary, this invention achieves synchronous dimensional adjustment of the support frame and folding struts through a twin-screw and gear linkage system, exhibiting strong dimensional adaptability. Its unique internal cuboid support structure provides rigid support for cardboard folding, ensuring forming accuracy and appearance quality. Combined with a precise mechanical transmission design, the equipment can efficiently complete the integrated fully automatic operation from conveying and positioning to 90-degree flipping and folding. The structure is compact and logically rigorous, significantly improving production efficiency and product consistency. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0020] Reference Figure 1-7 A fully automatic folding and forming equipment for cardboard box processing includes a conveying device 1. A forming frame 2 is fixedly installed at the upper center of the conveying device 1. A column 3 is fixedly installed at the lower part of the forming frame 2. Side seats 4 are provided on both the left and right sides of the lower part of the column 3, and side seats 5 are provided at the front and rear of the lower part of the forming frame 2. A rack seat 7 is fixed inside the side seats 4 and side seats 5. The rack seat 7 slides inside and outside the central column 3. Corner seats 6 are provided at the four corners of the lower part of the column 3, corresponding to the side seats 4 and side seats 5. The conveying device 1 includes... The system includes a conveyor base, two conveyor rollers, and a conveyor belt. The conveyor base is equipped with a drive device that connects to one of the conveyor rollers. The conveyor equipment 1 transports the corrugated cardboard with grooves cut into it until it is directly below the column 3. The opening and closing degree of the four corner seats 6 is adjusted according to the length and width of the carton. Specifically, this is achieved by sliding and adjusting the front and rear side seats 5 and the left and right side seats 4. The internal support of the cuboid formed by the two side seats 4, the two side seats 5, and the four corner seats 6 can provide stable internal support for the subsequent folding and forming of the carton. The corner seat 6 has a corresponding sliding groove for the side seat 4 and the side seat 5. The side seat 4 and the side seat 5 slide left and right between the two corner seats 6. A spur gear 8 is rotatably connected to the column 3 between two adjacent rack seats 7. The spur gear 8 meshes with both rack seats 7. A bevel gear 9 is fixed on the upper side of each spur gear 8. A bevel gear 10 is correspondingly meshed on the upper side of the bevel gear 9. Two screw rods 23 are rotatably connected to the upper part of the column 3. Synchronous pulleys 11 are fixed to the outer ends of the screw rods 23 and the outer side of the bevel gears 10. A corresponding synchronous belt 12 is sleeved on the outer side of the two synchronous pulleys 11 on the same side. Two sliding blocks 13 corresponding to the screw rods 23 are provided on the upper part of the column 3. The two sliding blocks 13 are threadedly connected to the two screw rods 23 respectively, and the sliding blocks 13 are slidably connected to the column 3. The above-mentioned two The cuboid structure composed of side seat 1 4, two side seats 2 5, and four corner seats 6 is specifically achieved by rotating the two screws 3 23 at the upper end of the column 3. The screws 3 23 are connected to the lower bevel gear 2 10 through the external upper and lower synchronous pulleys 11 and the corresponding synchronous belt 12. The bevel gear 2 10 drives the lower meshing bevel gear 1 9. The bevel gear 1 9 drives the lower fixed spur gear 8 to rotate. Through the spur gear 8, the two meshing rack seats 7 move towards each other or away from each other. The two side seats 1 4 or two side seats 2 5 connected to the outer end of the rack seat 7 open or close. Its outer corner seats 6 follow the movement of the side seats 1 4 or side seats 2 5. Since the upper screw 3 23 is threadedly connected to the slider block 13, the slider block 13 is specifically designed to fix the angle of the rotating screw 3 23, thereby achieving the result of adjusting the length and width of the lower cuboid. The conveying device 1 is equipped with two slide blocks 14. Each slide block 14 has a support bar 16 rotatably connected to its outer ends. Each end of the slide block 14 has a slide block 24 that slides inwards and outwards, with a support bar 22 rotatably connected to its outer end. The support bars 16 and 22 fold the carton into shape. Both slide blocks 14 slide left and right within the conveying base. Two screws 15 are rotatably connected within the conveying base of the conveying device 1. The two screws 15 are fixedly connected to each other and threadedly connected to the two slide blocks 14. The support bars 16 and 22 on both sides of the device base, in conjunction with the adjusted cuboid structure above, facilitate the handling of the transported paper. Before folding, the spacing between the two side support bars 22 and the spacing between the two side support bars 16 needs to be adjusted to match the length and width of the carton. Specifically, by rotating the two screws 15, the two threaded slides 14 are brought closer or further apart, thus adjusting the spacing between the two side support bars 16. By rotating the shaft 20 on the lower side of the slide 14, the screws 21 fixed at both ends of the shaft 20 are brought closer or further apart, thus adjusting the spacing between the two side support bars 22. Then, the four side support bars 16 and support bars 22 are rotated 90 degrees to achieve the purpose of folding the slotted carton. A rotating shaft 20 is rotatably connected to the lower part of slide block 14. Both ends of the rotating shaft 20 are fixed with screws 21, which are threadedly connected to the corresponding upper slide block 24. A motor 17 is fixedly mounted on slide block 24, and the output shaft of the motor 17 is fixedly connected to a support bar 22 on slide block 24. Both ends of slide block 14 are provided with rectangular groove rods 19, which slide inwards and outwards on slide block 14. The rectangular groove rods 19 and support bars 16 are located on the same rotation axis, and a rectangular through slot for the rectangular groove rod 19 is opened at the center of the transition part of support bar 16. The rectangular groove rod 19 is rotatably connected to the corresponding slide block 24. A bevel gear 3 18 is fixed to the outer end of the rectangular groove rod 19, and another bevel gear 3 18 that meshes with bevel gear 3 18 is fixed to the outer side of the transition part of support bar 22. When the rotating shaft 20 and the two screws 21 control the opening and closing of the two slides 24 on the slide 14, the rectangular groove rod 19 on it always maintains the linkage relationship with the support bar 16 on the slide 14. After the above spacing is determined, the motors 17 at the four corners are controlled to work. The output shaft of the motor 17 controls the rotation of the connected support bar 22. The bevel gear 18 fixed on the outside of the support bar 22 rotates. The bevel gear 18 drives another bevel gear 18 to rotate. The other bevel gear 18 is linked to the external support bar 16 through the rectangular groove rod 19. The support bars 16 and support bars 22 at the four corners rotate synchronously by 90 degrees, folding the conveyed cardboard. With the adjustment of the cuboid structure above, the slotted cardboard can be quickly folded and formed, and then glued and fixed by nailing or gluing equipment.
[0021] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
