Description

Technical Field

[0001] This application relates to the field of box-making machine technology, and more specifically, to a fully automatic box-making machine. Background Technology

[0002] Currently, fully automatic box-making machines have achieved full automation from cardboard cutting, crease pressing, box forming to material feeding and conveying, which has greatly improved the production efficiency of regular boxes such as square and rectangular boxes. The daily production capacity of a single machine can reach thousands to tens of thousands of pieces. At the same time, consumers have increasingly strict requirements for packaging quality. They not only require high precision in box forming, but also need to ensure that there is no surface damage or positional deviation in the material feeding process, so as to avoid subsequent assembly process jams or product scrap due to clamping problems. This places higher requirements on the adaptability and stability of the material feeding and clamping mechanism of the fully automatic box-making machine.

[0003] The feeding and clamping mechanisms of existing fully automatic box-making machines are mostly based on square or rectangular boxes, using a clamping structure with two sets of parallel plane clamps. When feeding round boxes, this structure requires manual disassembly of the original plane clamp assembly and replacement with a dedicated round clamping mechanism to achieve functional switching. This process increases additional labor costs. Furthermore, if the original plane clamps are used directly to clamp and feed round boxes, the contact between the plane clamps and the side wall of the box is limited by the geometric characteristics of the circular cross-section. During the conveying process, the round box is prone to circumferential rotation along its own axis or axial sliding along the clamping direction, which can lead to displacement of the feeding position. Operators need to frequently stop the machine to adjust the position of the box, thus affecting the continuity and stability of the production process. Utility Model Content

[0004] To address the aforementioned problems, this application provides a fully automatic box-making machine.

[0005] The fully automatic box-making machine provided in this application adopts the following technical solution: A fully automatic box-making machine includes a conveying mechanism and a paper box located on top of the conveying mechanism. The conveying mechanism includes two conveyor belts arranged perpendicular to each other. A fixed frame is fixedly installed on one side of the top of the conveying mechanism, and a feeding assembly is provided on one side of the fixed frame. The feeding assembly includes a clamping unit and a moving unit. The clamping unit includes two mounting boxes. Each mounting box has a flat clamping plate and a curved clamping plate on one side. A first motor is fixedly installed on one side of each mounting box. Each first motor is used to drive the corresponding flat clamping plate and curved clamping plate to move in opposite directions, thereby clamping paper boxes of different shapes.

[0006] Furthermore, each mounting box has an internal cavity, and each mounting box has a rotating shaft rotatably connected inside. The output end of each first motor passes through the corresponding mounting box and is fixedly connected to one end of the corresponding rotating shaft. Each rotating shaft has a gear fixedly connected to its outer wall.

[0007] Furthermore, each curved clamping plate and flat clamping plate is fixedly connected to the inner wall of the corresponding mounting box with at least one limiting telescopic rod, and each flat clamping plate and curved clamping plate is fixedly connected to a rack plate on the side near the gear, and both rack plates mesh with the corresponding gear.

[0008] Furthermore, each mounting box has two openings on one side, which are adapted to the corresponding flat clamping plate and curved clamping plate respectively.

[0009] The above technical solution allows for rapid adaptation to square or round cardboard boxes by moving the flat and curved clamping plates in opposite directions, significantly improving the equipment's compatibility with different shaped cardboard boxes and its changeover efficiency.

[0010] Furthermore, the moving unit includes two fixed guide rails, both of which are fixedly connected to the fixed frame. A second motor is fixedly installed on one side of each fixed guide rail. A threaded rod is rotatably connected inside each fixed guide rail. The output end of each second motor passes through one side of the corresponding fixed guide rail and is fixedly connected to one end of the corresponding threaded rod.

[0011] Furthermore, each fixed guide rail is provided with a movable plate on one side, one end of each movable plate is slidably connected to the inner wall of the corresponding fixed guide rail, and one side of each movable plate is threadedly connected to the corresponding threaded rod.

[0012] Furthermore, a first electric push rod is fixedly installed on one side of each movable plate, and the output end of each first electric push rod passes through the corresponding movable plate and is fixedly connected to one side of the corresponding mounting box.

[0013] Through the above technical solution, the first electric push rod in the moving unit can accurately adjust the installation box spacing according to the size of the cardboard box, adapt to cardboard boxes of different shapes and sizes, ensure stable clamping and prevent the cardboard box from falling off or deforming.

[0014] Furthermore, two centering rods are provided on the top side of the conveying mechanism, and two second electric push rods are fixedly installed on the top side of the conveying mechanism. The output end of each second electric push rod is fixedly connected to the side of the corresponding centering rod.

[0015] The above technical solution can quickly adjust the cardboard box that may be misaligned during feeding to the center position of the conveying mechanism.

[0016] In summary, this application includes at least one of the following beneficial technical effects: (1) This utility model drives the flat clamping plate and the arc clamping plate to move in opposite directions by the forward and reverse rotation of the first motor in the clamping unit, which can quickly adapt to square or round paper boxes, greatly improve the equipment's compatibility and changeover efficiency for paper boxes of different shapes. Furthermore, through the transmission of gears and racks, the dual guidance of the limiting telescopic rod and the opening, it can ensure that the clamping plate moves linearly and smoothly without deviation.

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] Reference Figures 1-7 A fully automatic box making machine includes a conveying mechanism 1 and a paper box located on top of the conveying mechanism 1. The conveying mechanism 1 includes two conveyor belts 2, which are arranged perpendicular to each other. A fixed frame 3 is fixedly installed on one side of the top of the conveying mechanism 1. A feeding assembly is provided on one side of the fixed frame 3. The feeding assembly includes a clamping unit and a moving unit. The clamping unit includes two mounting boxes 6. Each mounting box 6 has a flat clamping plate 7 and an arc-shaped clamping plate 8 on one side. Each mounting box 6 has a first motor 9 fixedly installed on one side. Each first motor 9 is used to drive the corresponding flat clamping plate 7 and arc-shaped clamping plate 8 to move in opposite directions, thereby clamping paper boxes of different shapes.

[0021] Reference Figures 1-7 Each mounting box 6 has an internal cavity, and each mounting box 6 has a rotating shaft 10 rotatably connected inside. The output end of each first motor 9 passes through the corresponding mounting box 6 and is fixedly connected to one end of the corresponding rotating shaft 10. Each rotating shaft 10 has a gear 11 fixedly connected to its outer wall. Each arc-shaped clamping plate 8 and flat clamping plate 7 has at least one limiting telescopic rod 13 fixedly connected to the inner wall of the corresponding mounting box 6. Each flat clamping plate 7 and arc-shaped clamping plate 8 has a rack plate 12 fixedly connected to its side near the gear 11. Both rack plates 12 mesh with the corresponding gear 11. Each mounting box 6 has two openings 14 on one side, and the two openings 14 are respectively adapted to the corresponding flat clamping plate 7 and arc-shaped clamping plate 8.

[0022] The clamping unit can adjust the shape of the clamping plate according to the shape of the cardboard box. Specifically, when the clamping plate needs to be adjusted according to the shape of the cardboard box (square or round), firstly, a corresponding control command is sent to the first motor 9 according to the shape of the cardboard box to be clamped. If a square cardboard box needs to be clamped, after the first motor 9 starts, its output end passes through the mounting box 6 and drives the rotating shaft 10, which is rotatably connected in the internal cavity, to rotate synchronously. The gear 11 fixed to the outer wall of the rotating shaft 10 rotates together with the rotating shaft 10. Since both the flat clamping plate 7 and the curved clamping plate 8 have rack plates 12 fixed on the side near the gear 11 that mesh with the gear 11, and both are connected by a limiting telescopic rod 13... The inner wall of the mounting box 6 is connected, and the limiting telescopic rod 13 can restrict the movement of the clamping plate to only in a straight line to avoid deviation. When the gear 11 rotates, it will drive the two rack plates 12 to move in opposite directions through meshing. At this time, since the target is a square cardboard box, the first motor 9 drives the gear 11 to rotate in the forward direction, so that the rack plate 12 connected to the flat clamping plate 7 extends outward along the opening 14. The opening 14 can guide the movement of the flat clamping plate 7 to ensure accurate extension trajectory. At the same time, the rack plate 12 connected to the curved clamping plate 8 retracts into the mounting box 6 along the opening 14 until the flat clamping plate 7 is fully extended and fits against the side wall of the square cardboard box to achieve stable clamping. If it is necessary to switch to clamping a round cardboard box, the first motor 9 rotates in the opposite direction, driving the rotating shaft 10 and gear 11 to rotate in the opposite direction. Through the meshing transmission of gear 11 and rack plate 12, the rack plate 12 connecting the arc-shaped clamping plate 8 extends outward along the opening 14, and the rack plate 12 connecting the flat clamping plate 7 retracts into the mounting box 6 until the arc-shaped clamping plate 8 is fully extended and fits against the side wall of the round cardboard box, thus completing the clamping plate shape adjustment.

[0023] The first motor 9 serves as the core driving component, offering advantages such as rapid start / stop response and stable speed. It can precisely control the rotation direction and angle of the rotating shaft 10, ensuring accurate and controllable clamp switching actions. Furthermore, the meshing of the rack plate 12 and gear 11 ensures high transmission precision, enabling linear and smooth movement of the clamps and guaranteeing the accuracy of their extension or retraction positions. Simultaneously, the limiting telescopic rod 13 not only provides limiting and guiding functions for the flat clamp 7 and the curved clamp 8, but its number can also be flexibly adjusted according to the clamp size, ensuring support stability. The flat clamp 7, with its smooth surface design, has a large contact area with the square cardboard box, resulting in strong stability when clamping the square cardboard box and reducing the likelihood of slippage. The curved clamp 8, conforming to the curved structure of the round cardboard box, increases the contact area with the round cardboard box, preventing it from rolling and ensuring clamping reliability.

[0024] By rotating the first motor 9 in the clamping unit in both forward and reverse directions, and through the precise transmission of the rotating shaft 10, gear 11, and rack plate 12, the flat clamping plate 7 and the curved clamping plate 8 are driven to move in opposite directions, quickly adapting to square or round cartons. This significantly improves the equipment's compatibility with different shaped cartons and its changeover efficiency. Furthermore, through the transmission of the gear 11 and rack plate 12, and the dual guidance of the limiting telescopic rod 13 and the through-hole 14, the clamping plates can be ensured to move linearly and smoothly without deviation. Combined with the large contact area of ​​the flat clamping plate 7 for square boxes and the curved fit of the curved clamping plate 8 for round boxes, the cartons are effectively prevented from slipping or rolling, improving clamping stability and feeding accuracy, and reducing defective products. In addition, the cavity of the box 6 can protect the internal components and extend the equipment's lifespan. Moreover, the entire operation is controlled by commands, requiring no complex manual intervention, ensuring continuous production, and ultimately improving the overall production efficiency and operational reliability of the carton making machine.

[0025] Reference Figures 1-5 The moving unit includes two fixed guide rails 4, both of which are fixedly connected to the fixed frame 3. A second motor 16 is fixedly installed on one side of each fixed guide rail 4. A threaded rod 17 is rotatably connected inside each fixed guide rail 4. The output end of each second motor 16 passes through one side of the corresponding fixed guide rail 4 and is fixedly connected to one end of the corresponding threaded rod 17. A moving plate 5 is provided on one side of each fixed guide rail 4. One end of each moving plate 5 is slidably connected to the inner wall of the corresponding fixed guide rail 4. One side of each moving plate 5 is threadedly connected to the corresponding threaded rod 17. A first electric push rod 15 is fixedly installed on one side of each moving plate 5. The output end of each first electric push rod 15 passes through the corresponding moving plate 5 and is fixedly connected to one side of the corresponding mounting box 6.

[0026] The moving components enable rapid unloading. Specifically, when the conveying mechanism 1 transports the cardboard box to the clamping area, it first sends a clamping command to the first electric push rod 15 on one side of the two moving plates 5 according to the size of the cardboard box. The output end of the first electric push rod 15 extends and retracts precisely, pushing the mounting box 6 fixedly connected to it to move horizontally. Since the two first electric push rods 15 move synchronously, the distance between the two mounting boxes 6 is controlled by adjusting the extension length until the flat clamping plate 7 or the curved clamping plate 8 on the mounting box 6 fits against the side wall of the cardboard box, thus achieving stable clamping of the cardboard box. The first electric push rod 15 has the advantages of stable pushing force and precise controllable extension stroke. It can flexibly adjust the clamping force and distance according to the size of the cardboard box, avoiding the cardboard box from falling off due to excessively loose clamping or deforming due to excessively tight clamping. After clamping, a synchronous drive command is sent to the second motor 16 on one side of the two fixed guide rails 4 according to the target position of the unloading. The second motor 16 starts, and its output end passes through the fixed guide rail 4 and drives the internally rotated threaded rod 17 to rotate synchronously. Since one end of the moving plate 5 is slidably connected to the inner wall of the fixed guide rail 4 and the other side is threadedly connected to the threaded rod 17, when the threaded rod 17 rotates, it drives the moving plate 5 to slide smoothly along the inner wall of the fixed guide rail 4 through the threaded transmission. Since the fixed guide rail 4 is fixedly connected to the fixed frame 3, the structure is stable and has strong guiding properties, providing a high-precision sliding path for the moving plate 5, preventing deviation during the sliding process, and ensuring the stability of the paper box conveying. While the moving plate 5 moves, it drives the first electric push rod 15, the mounting box 6 and the clamped paper box fixed on it to move synchronously until the paper box reaches directly above the unloading area. Subsequently, the first electric push rod 15 receives the retraction command, and the output end extends to push the mounting box 6 and the paper box to move. The retraction action of the first electric push rod 15 is smooth, which can avoid the paper box from shifting or being damaged due to impact. When the paper box is retracted to the preset length, the first electric push rod 15 stops moving, and the clamp on the mounting box 6 releases the paper box to complete the unloading. After the material is unloaded, the output end of the first electric push rod 15 retracts, causing the mounting box 6 to reset. The second motor 16 rotates in the opposite direction, driving the threaded rod 17 to rotate in the opposite direction, so that the moving plate 5 slides and resets along the fixed guide rail 4, waiting for the next unloading operation.

[0027] The first electric push rod 15 in the moving unit can precisely adjust the spacing of the mounting box 6 according to the size of the cardboard box, adapting to cardboard boxes of different shapes and sizes, ensuring stable clamping and preventing the cardboard box from falling off or deforming. With the help of the second motor 16 driving the threaded rod 17 for transmission, and in conjunction with the guide rail 4 guiding and limiting the moving plate 5, the clamped cardboard box can be moved smoothly and accurately to the unloading area, ensuring accurate unloading position without deviation. At the same time, it can quickly reset, ensuring continuous unloading in subsequent processes, effectively improving the overall production efficiency and unloading accuracy of the box making machine, reducing the generation of defective products, and further ensuring the long-term reliability of the moving unit.

[0028] Reference Figure 1 The top side of the conveying mechanism 1 is provided with two centering rods 18, and two second electric push rods 19 are fixedly installed on the top side of the conveying mechanism 1. The output end of each second electric push rod 19 is fixedly connected to the side of the corresponding centering rod 18.

[0029] The centering rod 18 can be precisely extended and retracted through the output end of the corresponding second electric push rod 19 to move towards the paper box from both sides and push the paper box. This quickly adjusts the paper box, which may be offset due to feeding, to the center position of the conveying mechanism 1, ensuring that the paper box can accurately enter the next stage in subsequent processes and avoiding the impact of positional offset on production continuity and processing accuracy.

[0030] Both the flat clamping plate 7 and the curved clamping plate 8 are equipped with pressure sensors on the side closest to the cardboard box. The pressure sensors are FUTEK LCM300 models. The pressure sensors are pre-linked with the equipment control system. The operator presets a safe clamping pressure threshold in the system according to the cardboard box material (e.g., 5-15N for ordinary cardboard boxes, 15-25N for cardboard boxes). When the clamping plate (flat clamping plate 7 or curved clamping plate 8) moves toward the cardboard box, the sensor transmits the contact pressure data to the control system in real time. If the pressure reaches the preset threshold, the system immediately sends a command to stop the clamping plate extension driven by the first motor 9 and controls the first electric push rod 15 to maintain the current clamping distance to avoid pressure overload causing deformation of the cardboard box. At the same time, the pressure sensor can dynamically monitor pressure fluctuations during the clamping process (e.g., pressure changes caused by slight deformation of the cardboard box). If the pressure is lower than the threshold, the system drive component fine-tunes the clamping plate position to supplement the pressure and ensure stable clamping. If the pressure suddenly increases (e.g., abnormal jamming), the overload protection is triggered, causing the clamping plate to slightly retract, which ensures clamping accuracy and completely avoids damage to the cardboard box.

[0031] The controllers and pressure sensors mentioned above are all existing technologies and will not be described in detail here.

[0032] Working principle: First, the cardboard box to be processed is placed on two mutually perpendicular conveyor belts 2 of the conveying mechanism 1. The conveyor belts 2 transport the cardboard box to the material unloading component clamping area on one side of the fixed frame 3. When the cardboard box reaches the clamping area, the clamping unit initiates the corresponding action according to the shape of the cardboard box (square or round). That is, it sends a control command to the first motor 9 on one side of the two mounting boxes 6. The first motor 9 drives the rotating shaft 10 connected inside the mounting box 6 and the gear 11 fixed on the outer wall to rotate. Through the meshing transmission of the gear 11 with the rack plate 12 on one side of the flat clamping plate 7 and the curved clamping plate 8, and with the guidance of the limiting telescopic rod 13 and the opening 14, the flat clamping plate 7 (square cardboard box) or the curved clamping plate 8 (round cardboard box) extends and fits against the side wall of the cardboard box. At the same time, the first electric push rod 15 on one side of the two moving plates 5 in the moving unit extends and retracts synchronously to adjust the distance between the two mounting boxes 6 and achieve stable clamping of the cardboard box. After clamping is completed, the second motor 16 of the moving unit starts and drives the threaded rod 17 inside the fixed guide rail 4 to rotate. Through the threaded connection between the threaded rod 17 and the moving plate 5 and the guidance of the fixed guide rail 4, the moving plate 5, the first electric push rod 15, the mounting box 6 and the clamped cardboard box are moved smoothly to the top of the unloading area. Then the first electric push rod 15 retracts to the preset length and the clamping plate is released to complete the unloading. After the material is unloaded, the first electric push rod 15 retracts, causing the mounting box 6 to reset. The second motor 16 rotates in the opposite direction, causing the moving plate 5 to reset along the fixed guide rail 4. At the same time, the second electric push rod 19 at the top of the conveying mechanism 1 drives the centering rod 18 to move closer from both sides, adjusting any potentially misaligned cardboard boxes to the center position of the conveying mechanism 1, ensuring that subsequent cardboard boxes can accurately enter the next process. This cycle is repeated to achieve fully automatic box making and unloading operations.
