Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a fully automatic cardboard box corner folding device. Background Technology

[0002] In the modern logistics and packaging industry, cardboard boxes are commonly used packaging containers, and their production and processing have gradually moved towards automation and intelligence. The fully automatic cardboard box corner folding device, as a key piece of equipment in the cardboard box forming process, can realize the automation of cardboard box corner folding, shaping and other processes, which greatly improves cardboard box production efficiency, reduces manual labor intensity, meets the needs of large-scale cardboard box production, and is an indispensable and important part of the current cardboard box processing production line. Because the heights of cartons of different sizes vary, the existing carton placement platforms in most devices are fixed structures, unable to be flexibly adjusted according to carton height. When processing taller cartons, the top of the carton is difficult to precisely align with the corner folding mechanism, easily leading to corner misalignment and irregular corners. When processing shorter cartons, the bottom of the carton does not align well with the device's conveyor structure, potentially causing carton conveying jams and affecting the smoothness of the overall processing flow. This severely restricts the device's adaptability to different carton sizes. To solve these height adaptability problems, existing technologies typically use dedicated placement platforms for cartons of different heights as an improvement. However, in actual use, this solution requires manual platform replacement when changing the carton size being processed. This not only requires preparing multiple platforms, increasing equipment costs, but also takes a long time to change, reducing production efficiency. Utility Model Content

The lifting mechanism 2 includes two columns 201, both of which are fixedly connected to the middle of the frame 1. A threaded rod 202 is rotatably connected inside the rear column 201, and a support rod 204 is fixedly connected inside the front column 201. A working surface 203 is provided on the front side of the threaded rod 202. A drive assembly 205 is installed on the bottom right side of the frame 1, and a transmission assembly 206 is installed on the front side of the bottom end of the threaded rod 202. The drive assembly 205 includes a motor 2051, model Y132S2-2. After being energized, a three-phase alternating current is passed through the stator winding to generate a rotating magnetic field, which cuts the rotor winding to generate an induced current, thereby generating an electromagnetic torque to drive the rotor to rotate. The motor 2051 is installed on the right side of the front column 201. A drive gear 2052 is fixedly connected to the output end of the motor 2051, and a driven gear 2053 is meshed on the left side of the drive gear 2052. The transmission assembly 206 includes a first rotating shaft 2061, which passes through the middle of the driven gear 2053. A first bevel gear 2062 is fixedly connected to the rear end of the outer wall of the first rotating shaft 2061. A second bevel gear 2063 is meshed with the top of the first bevel gear 2062. The second bevel gear 2063 is fixedly connected to the bottom end of the outer wall of the threaded rod 202. A movable frame 2064 is threadedly connected to the outer wall of the threaded rod 202. The front side of the movable frame 2064 is slidably connected to the outer wall of the support rod 204. The first rotating shaft 2061 is rotatably connected to the bottom end of the two columns 201. The working surface 203 is fixedly connected to the top wall of the movable frame 2064. A motor bracket 4 is fixedly connected to the right side of the bottom end of the outer wall of the front column 201. A first motor 2051 is fixedly connected to the top wall of the motor bracket 4. Specifically, the output shaft of motor 2051 is fixedly connected to the central shaft of drive gear 2052. When energized, it drives drive gear 2052 and its meshing driven gear 2053 to rotate synchronously. The central hole of driven gear 2053 is interference-fitted with one end of shaft 2061, causing shaft 2061 to rotate around its own axis. The other end of shaft 2061 is fixedly connected to the center of bevel gear 2062 via a key. The rotation of shaft 2061 causes bevel gear 2062 to rotate along with it. The teeth of bevel gear 2062 mesh with the teeth of bevel gear 2063, driving the rotation of the threaded rod 202, which is coaxially fixed with bevel gear 2063, through gear meshing transmission. The upper and lower ends of threaded rod 202 are respectively mounted in pre-set mounting holes inside the rear column 201 via bearings. The rear column 201 rotates around its own axis while maintaining its axial position. The rear part of the movable frame 2064 has a threaded hole with an internal thread that meshes with the external thread on the surface of the threaded rod 202. As the threaded rod 202 rotates forward and backward, the movable frame 2064 moves the working surface 203 up and down along the axis of the threaded rod 202 under the action of threaded transmission. The height of the working surface 203 can be adjusted to meet the needs of placing cartons of different specifications and sizes. The upper and lower ends of the support rod 204 are connected to the mounting base inside the front column 201 through bearings. It can rotate freely in the front column 201 and has a smooth, threadless surface. The front side of the movable frame 2064 has a through hole that fits on the surface of the support rod 204. When the movable frame 2064 moves up and down, the support rod 204 restricts its lateral displacement and serves as a guide for the movement path.

[0018] Reference Figure 4 and Figure 5 Each of the multiple adjustment mechanisms 3 includes a mounting base 301, which is installed around the top of the frame 1. Sliding plates 302 are slidably connected to the front and rear sides of the inner top wall of the mounting base 301. A rack 303 is fixedly connected to the top of each of the two sliding plates 302. An adjustment gear 304 is meshed on the inner side of the two racks 303. A connecting rod 305 passes through the middle of the adjustment gear 304. The connecting rod 305 is rotatably connected to the middle of the top of the mounting base 301. A locking component 306 is provided on the top of the adjustment gear 304. The locking assembly 306 includes a ratchet 3061, which is fixedly connected to the bottom outer wall of the connecting rod 305. Pads 3062 are installed on both the left and right sides of the ratchet 3061. Both pads 3062 are installed in the middle of the inner top wall of the mounting base 301. Compression springs 3063 are fixedly connected to the middle of the outer wall of both pads 3062. A knob 6 is fixedly connected to the top of the connecting rod 305. Multiple anti-slip teeth 7 are fixedly connected at equal intervals to the outer wall of the knob 6. Specifically, two sliding plates 302 are respectively embedded in two parallel sliding grooves opened on the top of the mounting base 301, and can slide horizontally along the sliding grooves in the mounting base 301. By changing the distance between the two sliding plates 302, it can adapt to cartons of different widths. Rotating the connecting rod 305, one end of the connecting rod 305 passes through the side wall of the mounting base 301 and is fixedly connected to the central shaft of the adjusting gear 304. It drives the adjusting gear 304 to rotate around the central shaft. The top teeth of the adjusting gear 304 simultaneously mesh with the racks 303 on the top of the two sliding plates 302. As the adjusting gear 304 rotates, the two racks 303 move in opposite directions on both sides of the adjusting gear 304, causing the two sliding plates 302 to move away from each other, expanding the coverage area of ​​the two sliding plates 302 and increasing the folding area. The ratchet 3061 is coaxially fixed with the adjusting gear 304. The pawl 3062 is hinged to the side wall of the mounting base 301 by a pin, and its end engages with the teeth of the ratchet 3061 to form a one-way locking structure to prevent the ratchet 3061 and the adjusting gear 304 from rotating in opposite directions. This prevents the slider 302 from retracting under external force due to the reverse rotation of the adjusting gear 304. One end of the compression spring 3063 is fixed to the side wall of the mounting base 301, and the other end contacts the middle of the pawl 3062 to press the ratchet 3061, so that the pawl 3062 and the ratchet 3061 are always tightly engaged to prevent the ratchet 3061 from loosening. A certain amount of external force needs to be applied to push the pawl 3062 to compress the compression spring 3063 in order to pull the slider 302 to adjust its position, ensuring the stability of the slider 302 after adjustment.

[0019] Reference Figure 1 and Figure 2 Two motors 8 are installed on the top rear side and left side of the frame 1. The output ends of the multiple motors 8 are fixedly connected to the rotating shafts 5. The outer walls of the multiple rotating shafts 5 are fixedly connected to the top of the mounting base 301. Specifically, motor 28 is bolted to the left and rear crossbeams at the top of frame 1 to provide power for the angle bending operation. There are two motors on each of the two crossbeams. Rotary shaft 25 connects motor 28 and mounting base 301. Under the drive of rotating shaft 25, it drives the motor to rotate and perform the angle bending operation.

[0020] Working principle: Motor 2051 drives the driving gear 2052 and driven gear 2053 to rotate. Driven gear 2053 drives shaft 2061 to rotate. The rotation of shaft 2061 causes bevel gear 2062 to start working. Through meshing with bevel gear 2063, it drives the threaded rod 202 to rotate. The threaded rod 202 rotates within the rear column 201 without changing its position. The rear part of the moving frame 2064 is provided with threads that mesh with the surface of the threaded rod 202. As the threaded rod 202 rotates... The movable frame 2064 drives the working surface 203 to move up and down to adapt to cartons of different specifications and sizes. The support rod 204 rotates inside the front column 201 and has a smooth surface. The front side of the movable frame 2064 is fitted onto its surface to guide the movement path. This set of mechanisms can quickly and accurately change the vertical position of the working surface 203 as needed. Only one set of mechanisms is needed to ensure that cartons of different heights can be located at the optimal processing height, solving the problems of increased equipment cost, long time consumption and low efficiency in the existing technology. The slider 302 slides in the mounting base 301 to adapt to cartons of different widths. Rotating the connecting rod 305 drives the adjusting gear 304 to rotate. The top of the adjusting gear 304 meshes with the rack 303 on the top of the slider 302. As the adjusting gear 304 rotates, the two racks 303 move in opposite directions, and the two sliders 302 move away from each other, increasing the folding area. The pawl 3062 engages with the teeth of the ratchet 3061 to prevent the ratchet 3061 and the adjusting gear 304 from rotating in opposite directions. This causes the slider 302 to retract under external force. The compression spring 3063 presses the ratchet 3061 to prevent it from loosening. A certain amount of external force is required to pull the slider 302 to ensure adjustment stability.
