Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, specifically to an automatic folding device for straight-edge card boxes. Background Technology

[0002] Straight-edge cardboard boxes are single-piece packaging boxes made from cardboard or grey-backed white cardboard. They are formed into cuboid or polygonal structures through folding and gluing, with a small opening surface, and belong to the typical "tubular" packaging form. Their simple structure and low cost make them widely used for lightweight packaging of food, pharmaceuticals, and daily necessities. However, their cushioning performance is limited. The introduction of automatic folding technology has completely changed the paper box production model—fully automatic box-making machines, through servo control systems and photoelectric sensing technology, automatically complete the entire process of feeding, gluing, folding, and forming, increasing production efficiency several times over. Digital parameter control minimizes folding accuracy errors. However, current equipment still faces the challenge of insufficient flexibility in quickly adapting to different sized paper boxes. While existing technologies may already offer solutions to these problems, this paper aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic folding device for straight-edge card boxes, comprising: a device base, a bearing top plate, and a pair of first bearing seats, the pair of first bearing seats being respectively installed on the device base, a combined folding structure being installed on the device base, and a pressing auxiliary shaping structure being installed on the bearing top plate, the combined folding structure comprising: a pair of alignment deflection protective shells, electric tracks, a pair of second bearing seats, a folding power motor, a transmission distribution gearbox, and a pair of bending and folding components;

[0004] A pair of alignment deflection protective shells are respectively mounted on a pair of first bearing seats, a pair of second bearing seats are respectively mounted inside the device base, the electric track is mounted on the device base, the folding power motor is mounted inside the device base, the transmission distribution gearbox is inserted into the device base and is connected to the folding power motor, and a pair of bending and folding components are respectively mounted on a pair of alignment deflection protective shells and a pair of second bearing seats;

[0005] The bending and folding assembly includes: a positioning deflection motor, a positioning deflection turntable, a coordinating push electric push rod, a push brush head, a first transmission shaft, a first drive turntable, a pair of second drive turntables, a second transmission shaft, a third transmission shaft, a pair of mounting bearings, several adjusting hydraulic telescopic rods, a pair of branch folding blocks, a rotary folding block, and a pair of connecting eccentric blocks.

[0006] The alignment deflection motor is installed inside the alignment deflection protective shell. The alignment deflection turntable is connected to the alignment deflection motor via a rotating shaft. The coordinating push electric push rod is installed on the alignment deflection turntable. The push brush head is installed on the coordinating push electric push rod. The first transmission shaft is connected to the transmission distribution gearbox. The first drive turntable is installed on the first transmission shaft, and the first drive turntable and the second drive turntable mesh with each other. A pair of second drive turntables are respectively connected to the second transmission shaft and the third transmission shaft. A pair of mounting bearings are respectively installed on the second bearing seat, and a pair of mounting bearings are respectively connected to the second transmission shaft and the third transmission shaft. A plurality of adjusting hydraulic telescopic rods are respectively installed on the rotary folding block. A pair of branch folding blocks are respectively connected to a plurality of adjusting hydraulic telescopic rods. The rotary folding block is respectively connected to a pair of connecting eccentric blocks via a rotating shaft. A pair of connecting eccentric blocks are respectively connected to the second transmission shaft and the third transmission shaft.

[0007] It should be noted that, as described above, the cardboard box blank to be folded is placed on the electric track on the device base. The operation of the electric track drives the cardboard box blank until it reaches the space between a pair of coordinated pushing electric push rods. At this point, the pair of coordinated pushing electric push rods automatically adjust their relative lengths according to the size and width of the cardboard box blank. Simultaneously, the alignment deflection motor inside the alignment deflection protective shell operates, causing the corresponding alignment deflection turntable to deflect, which in turn causes the coordinated pushing electric push rods mounted on it to deflect in tandem. At the same time, the pair of coordinated pushing electric push rods adjust their reciprocating extension and retraction based on whether the cardboard box blank is in the center of the electric track, and push the cardboard box blank to the center of the electric track through a pair of pushing brush heads, thus facilitating subsequent folding and bending. Then, the folding power motor inside the device base drives the transmission distribution gearbox, which in turn distributes power to a pair of first transmission gears. The rotating shaft drives a pair of first transmission shafts, causing the corresponding first drive turntable to rotate. Since the first and second drive turntables mesh with each other via meshing gear rings on the first drive turntable, the second drive turntable rotates along the bearing and the second transmission shaft, causing the connecting eccentric block to rotate. This drives the rotating folding block on the eccentric block to move and shift. The adjacent second drive turntable is also driven by the third transmission shaft and the bearing. Driven by the coordinated rotation of the pair of second drive turntables, the rotating folding block performs a reciprocating rotational motion. Multiple adjustable hydraulic telescopic rods on one side extend and retract in tandem, allowing a pair of branch folding blocks to move to the optimal folding position, thus accommodating more sizes of cardboard box blanks. The operation panel on the device base allows for adjustment and parameter calibration of the entire process, while the emergency stop button on the device base allows for emergency stopping of the device in case of an emergency.

[0008] Preferably, the pressing auxiliary shaping structure includes: a top receiving platform, a pressing power motor, a transmission screw, a pair of cooperating connecting rods, a secondary connecting block, a pressing top plate, an adjustment displacement module, and a pair of mounting connecting flanges;

[0009] The top support platform is mounted on the bearing top plate, the downward pressure motor is mounted on the top support platform, the transmission screw is mounted on the top support platform and connected to the downward pressure motor, a pair of cooperating connecting rods are respectively mounted on the secondary connecting block via rotating shafts, the secondary connecting block is connected to the downward pressure top plate, a pair of cooperating connecting rods are respectively connected to the top support platform and the adjustment displacement module via rotating shafts, the adjustment displacement module is fitted on the transmission screw, and a pair of mounting connecting flanges are respectively mounted on the bearing top plate;

[0010] It should be noted that, as described above, the top plate is properly fixed to the ceiling by a pair of mounting flanges. When the downward power motor on the top support platform is driven, the transmission screw is rotated. The rotating transmission screw drives the adjustment displacement module to move through its thread. The displacement adjustment displacement module then drives a pair of cooperating connecting rods to move synchronously, thereby causing the secondary connecting block to move downward. The moving secondary connecting block then drives the downward pressure top plate to move downward until it touches the top of the carton blank, completing the calibration and positioning of the carton blank, thus facilitating the bending of the carton blank.

[0011] Preferably, the first drive turntable is provided with a meshing toothed ring;

[0012] Preferably, the device base is provided with a maintenance and inspection port;

[0013] Preferably, an emergency stop button is provided on the base of the device;

[0014] Preferably, an operation panel is provided on the base of the device;

[0015] Beneficial effects

[0016] This utility model provides an automatic folding device for straight-edge cardboard boxes. Compared with existing technologies, this automatic folding device for straight-edge cardboard boxes achieves precise positioning and adjustment of the cardboard box blank through the synergistic effect of a combined folding structure and a pressing-assisted shaping structure. When the blank is conveyed to the designated position on the electric conveyor belt, four branch folding blocks synchronously advance towards the center, applying uniform pressure to the fixed blank to complete the three-dimensional folding and forming action. The entire processing flow can be digitally controlled through preset program parameters. Engineers only need to adjust the equipment parameters to adapt to cardboard box blanks of different sizes and specifications, significantly improving production compatibility.

[0025] According to the appendix Figure 1-3The process involves placing the cardboard box blank requiring folding onto the electric track 9 on the device base 1. The operation of the electric track 9 drives the cardboard box blank until it reaches the space between a pair of coordinated pushing electric actuators 7. At this point, the pair of coordinated pushing electric actuators 7 automatically adjust their relative lengths according to the size and width of the cardboard box blank. Simultaneously, the alignment deflection motor 5 inside the alignment deflection protective housing 4 operates, causing the corresponding alignment deflection turntable 6 to deflect. This deflection further causes the coordinated pushing electric actuators 7 mounted on it to deflect in tandem. Furthermore, the pair of coordinated pushing electric actuators 7 adjust their reciprocating extension and retraction based on whether the cardboard box blank is in the center position of the electric track 9. The cardboard blank is pushed to the center of the electric track 9 by a pair of push-position brush heads 8, facilitating subsequent folding and bending. Then, the folding power motor 11 in the drive unit base 1 drives the transmission distribution gearbox 12 to operate. The transmission distribution gearbox 12 further distributes power to a pair of first transmission shafts 13, thus driving the pair of first transmission shafts 13 to operate, thereby causing the corresponding first drive turntable 14 to start rotating. Since the first drive turntable 14 and the second drive turntable 15 are meshed with each other by the meshing toothed ring provided on the first drive turntable 14, the second drive turntable 15 is supported by the bearing 18 and the second transmission... The rotating shaft 16 begins to rotate, causing the connecting eccentric block 22 to rotate, which in turn drives the rotating folding block 21 on it to move and change position. The adjacent second drive turntable 15 is simultaneously actuated by the third transmission shaft 17 and the mounting bearing 18. Driven by the coordinated rotation of the pair of second drive turntables 15, the rotating folding block 21 performs a reciprocating rotary motion. Meanwhile, multiple adjusting hydraulic telescopic rods 19 on one side extend and retract in tandem, allowing a pair of branch folding blocks 20 to move to the optimal folding position, thus accommodating more sizes of cardboard box blanks. The operation panel on the device base 1 allows for adjustment and parameter calibration of the entire process. The device base 1 also features an emergency... The stop button allows for emergency stop of the device in case of emergency. The top plate 2 is securely fixed to the ceiling by a pair of mounting flanges 30. When the downward power motor 24 on the top support platform 23 is driven, the transmission screw 25 is rotated. The rotating transmission screw 25 drives the adjustment displacement module 29 to move through its threads. The displacement adjustment displacement module 29 then drives a pair of cooperating connecting rods 26 to move synchronously, thereby causing the secondary connecting block 27 to move downward. The moving secondary connecting block 27 then drives the downward pressure top plate 28 to move downward until it touches the top of the carton blank, completing the calibration and positioning of the carton blank, thus facilitating the bending of the carton blank.
