Description

Technical Field

[0001] The present invention relates to the technical field of carton production, and in particular to an anti-fall paper shell and processing equipment thereof. Background Art

[0002] Cardboard boxes, a fundamental material in modern logistics and packaging, are primarily used for product transportation, storage protection, and merchandise display. Corrugated cardboard achieves a balance between lightweight and compressive strength through structural design. Surface printing can also carry brand information, combining practicality with marketing capabilities. The core processing equipment is a fully automatic folding and gluing production line. First, the raw cardboard is pre-creased by a creasing machine. Then, it passes through a conveyor belt into a folding unit. A robotic arm, coupled with a rotary mold, rapidly forms the box. Finally, the bottom is sealed with hot-melt adhesive, resulting in a standardized box capable of carrying 5-50 kg. Widely used in industries such as e-commerce, food, and electronics, it serves as an important, reusable, and environmentally friendly carrier in the circular economy.

[0003] Currently, the compression-resistant structure of cardboard-based cartons on the market mostly relies on the corrugated design inside the cardboard. However, this structure has obvious shortcomings - it can only provide basic support, but cannot effectively limit the products inside the box. Once the carton is shaken or accidentally dropped, the internal products are very likely to collide with each other and rub against the box body due to lack of fixation, eventually causing damage, making it difficult to provide comprehensive protection for the products. At the same time, in order to ensure the precise formation of the cardboard during operation, the existing cardboard folding equipment often adopts a step-by-step folding method, that is, after one side of the cardboard is completely folded into place, the other side is folded. Although this method can ensure folding accuracy, it undoubtedly prolongs the forming time of a single carton, which greatly reduces the overall processing efficiency of the cardboard folding equipment, making it difficult to meet the needs of large-scale, high-efficiency production.

[0004] Furthermore, we disclose a drop-resistant paper shell and its processing equipment to meet the actual needs of the existing technology where cartons made of corrugated paper shells lack limit protection, resulting in easy damage to the product, and the processing efficiency of step-folding equipment is low. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to propose a shatter-proof paper shell and its processing equipment to meet the following practical needs in the prior art: on the one hand, in view of the problem that the existing corrugated cardboard boxes only rely on the corrugated structure to provide compressive support, but lack effective limiting and fixing of the products, the shatter-proof paper shell has an innovative structural design and adds a customizable limiting component inside the carton, which can provide stable support and cushioning protection for various products in different transportation scenarios, significantly reducing the risk of shaking and collision of products during transportation, thereby effectively avoiding product damage; on the other hand, in order to overcome the disadvantages of low processing efficiency caused by the step-by-step folding of existing paper shell folding equipment, the accompanying processing equipment adopts advanced synchronous folding technology, and by optimizing the mechanical structure and control system, realizes the coordinated folding of multiple parts of the paper shell, greatly shortens the forming time of a single carton, and significantly improves the overall processing efficiency of the equipment, so as to better adapt to the large-scale and high-efficiency production rhythm of modern industry.

[0010] A kind of anti-fall paper shell processing equipment uses the above-mentioned anti-fall paper shell, including a processing frame for placing the carton body, a loading and unloading robot arm for picking up and placing the carton body, and a conveying mechanism for completing the conveying work. The carton body is placed on the upper end of the processing frame by the loading and unloading robot arm. The upper end of the processing frame is provided with a folding assembly, and the folding assembly is used to complete the folding of the carton body into a box. The middle part of the processing frame is provided with a clamping assembly, and the clamping assembly is used to complete the limiting work of the carton body when the folding assembly is working.

[0011] Preferably, the folding assembly includes a rotating frame respectively arranged in the middle of the four side surfaces of the upper end of the processing frame, an open groove is opened in the middle of the four side walls of the upper end of the processing frame, one end of the rotating frame is located inside the open groove and is fixedly connected to a rotating shaft, the rotating frame is rotatably connected to the processing frame through the rotating shaft, the connection between the rotating shaft and the processing frame is sleeved with a torsion spring, the lower end of the rotating frame close to the processing frame is fixedly connected to a rotating plate, the rotating plate is inclined, and a plurality of rotating wheels are rotatably connected at even intervals on the side of the rotating frame away from the rotating shaft, and the outer wall of the rotating wheel is in contact with the carton body.

[0012] Preferably, the folding assembly also includes a mounting plate fixedly connected to the lower end of the processing frame, a telescopic cylinder is installed in the middle of the upper end surface of the mounting plate, the output end of the telescopic cylinder is fixedly connected to a fixed cylinder, the upper end of the fixed cylinder is fixedly connected to a cross, the four sides of the cross are rotatably connected to rollers, the outer walls of the four rollers are respectively in contact with the outer walls of the four rotating plates, guide rods are fixedly connected on both sides of the lower end of the middle part of the processing frame, the lower ends of the two guide rods pass through the cross and are slidably connected to the cross.

The multi-stage cylinder is used to push the folded carton body onto the conveying mechanism. The upper end of the conveying mechanism is located on both sides of the conveyor belt and a limiting frame is installed to limit the moving path of the carton body.

[0016] Beneficial effects of the present invention:

[0017] 1. This shatter-resistant paper box and its processing equipment address the problem of traditional cartons lacking internal limits, which makes products fragile. The L-shaped structure formed by the folded stabilizing plate and the arched lower end constitute a double buffering and limiting mechanism. The dynamic coupling design of its inclined guide rod and contact plate ensures that the product is both elastically squeezed and limited when placed, while avoiding rigid impact, significantly improving its seismic protection capabilities. Compared with traditional planar support structures, the synergistic effect of the arched contact plate and the crease not only ensures that the stabilizing plate is directional bent to form a three-dimensional support skeleton, but also optimizes the crease position to tilt the lower end inward, further reducing the product displacement space and achieving three-dimensional precise positioning. The all-paper material and glue bonding process not only ensures structural strength while avoiding the pollution risks caused by rusting metal parts or aging plastic parts.

[0018] 2. The anti-fall paper box and its processing equipment significantly improve the processing efficiency through the linkage folding mechanism: a telescopic cylinder is used to drive the cross to synchronously link the four-side rotating frames. With the help of the coordinated cooperation of the elastic potential energy of the torsion spring and the rolling friction of the roller, the synchronous folding of various parts of the paper box in a single vertical movement is achieved, which completely changes the traditional step-by-step operation mode and greatly shortens the single-box forming cycle; the sliding guide structure of the cross and the guide rod effectively solves the problem of crease offset caused by discrete folding, ensures that the pressing force on the four sides is evenly distributed, and cooperates with the precise guidance of the wheel along the folding groove to significantly improve the crease positioning accuracy and avoid the problem of box structure instability caused by crease deflection; the elastic preload and linkage pressing mechanism not only reduces the repeated positioning operation of the robot arm and reduces the energy consumption of the equipment, but also the rolling contact method of the wheel effectively avoids the damage to the paper box surface caused by traditional pressing plate, comprehensively improving the appearance quality and structural strength of the paper box finished product, and perfectly meets the modern packaging industry's requirements for efficient, precise and low-consumption processing.

[0019] 3. The anti-drop paper shell and its processing equipment utilize a dual limiting structure of suction cups and convex balls. Gravity triggers the suction cups to contract and form an initial position the moment the paper shell is placed. During the folding process, the negative pressure adsorption system is simultaneously activated. The sealed cooperation between the piston column and the piston cylinder generates a continuous downward adsorption force. The rigid blocking of the convex balls enables precise positioning of the paper shell, ensuring that there is no displacement throughout the folding process. Compared with the traditional single mechanical limiting method, this design deeply couples the adsorption limit with the folding action, avoiding damage to the paper shell surface caused by mechanical clamping. It also adapts to the processing requirements of paper shells of different specifications through dynamic negative pressure adjustment, significantly improving folding accuracy and equipment compatibility.

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical or scientific terms used in the present invention should have the usual meanings understood by people with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0033] like Figures 1 to 3 As shown, a drop-proof paper shell includes a paper shell body 1 composed of six paper boards, and each paper board is connected with a folding groove for folding it. Both sides of the middle of the upper end surface of the paper shell body 1 are provided with a stabilizing document. The stabilizing component is used to buffer and limit the product inside the paper shell body 1. The stabilizing component includes a stabilizing plate 2. Both ends of the stabilizing plate 2 are respectively fixedly connected to the two paper boards on the paper shell body 1. A fold 4 is provided on one side of the middle of the stabilizing plate 2. A fold 4 is provided on the stabilizing plate 2 at the lower end of the fold 4. There is a contact plate 5, which is in the shape of an arch bridge and the upper end of which contacts the stabilizing plate 2, and the position of the fold 4 on the stabilizing plate 2 is arched upward. The stabilizing component also includes two guide rods 3, which are respectively arranged on both sides of the stabilizing plate 2, and the lower ends of the guide rods 3 are fixedly connected to the paper shell body 1. The guide rods 3 are inclined inwardly, and the end surfaces of both sides of the stabilizing plate 2 are located on one side of the fold 4 and are fixedly connected with a contact plate 12. The contact plate 12 is arc-shaped and will contact the paper shell body 1 when the paper shell body 1 is folded;

[0034] When the carton body 1 is folded into a box, the carton in the middle of the carton body 1 is stable and immovable. When the cardboard outside the middle carton is folded inward by the folding device, the stabilizing plate 2 is folded by the action of the crease 4. When the cardboard is folded, the stabilizing plate 2 forms an L shape inside the carton. And because the contact plate 12 will contact the guide rod 3 when the stabilizing plate 2 rotates, and the guide rod 3 is inclined, the lower end of the stabilizing plate 2 will be an arch after folding. When the product is put into the interior later, it will squeeze the product to complete the limiting work. In addition, The function of the resistance plate 5 is to press the position of the crease 4 of the stabilizing plate 2 upward to ensure that when folding, the stabilizing plate 2 will bend to the side away from the resistance plate 5 through the crease 4 and will not fold inward. In addition, the position of the crease 4 on the stabilizing plate 2 is closer to the side of the rotating cardboard, so that the lower end of the stabilizing plate 2 will tilt inward after folding, further strengthening the limiting work of the internal product; all structures on the stabilizing component are made of paper and are connected to the paper shell body 1 by glue bonding, which is within the scope well known to those skilled in the art.

[0035] Further, such as Figures 4 to 8 As shown, the present invention also discloses an anti-fall paper shell processing equipment, including a processing frame 9 for placing a paper shell body 1, a loading and unloading mechanical arm 8 for picking up and placing the paper shell body 1, and a conveying mechanism 6 for completing the conveying work. The paper shell body 1 is placed on the upper end of the processing frame 9 through the loading and unloading mechanical arm 8. The upper end of the processing frame 9 is provided with a folding component, which is used to complete the folding of the paper shell body 1 into a box. The middle part of the processing frame 9 is provided with a pressing component, which is used to complete the limiting work of the paper shell body 1 when the folding component is working. The folding component includes a rotating frame 14 respectively arranged in the middle of the four side surfaces of the upper end of the processing frame 9, and an open groove 17 is opened in the middle of the four side walls of the upper end of the processing frame 9. One end of the rotating frame 14 is located inside the open groove 17 and is fixedly connected to a rotating shaft 23. The rotating frame 14 is rotatably connected to the processing frame 9 through the rotating shaft 23, and the rotating shaft 23 is connected to the processing frame 9. The connection points of the processing frame 9 are all sleeved with torsion springs 22. The lower end of the rotating frame 14 close to the processing frame 9 is fixedly connected to a rotating plate 21. The rotating plate 21 is tilted, and the side of the rotating frame 14 away from the rotating shaft 23 is evenly spaced and rotatably connected to multiple wheels 15. The outer wall of the wheel 15 is in contact with the paper shell body 1. The folding assembly also includes a mounting plate 18 fixedly connected to the lower end of the processing frame 9. A telescopic cylinder 20 is installed in the middle of the upper end surface of the mounting plate 18. The output end of the telescopic cylinder 20 is fixedly connected to a fixed cylinder 27. The upper end of the fixed cylinder 27 is fixedly connected to a cross 19. The four sides of the cross 19 are rotatably connected to rollers 26. The outer walls of the four rollers 26 are respectively in contact with the outer walls of the four rotating plates 21. Guide rods 25 are fixedly connected to both sides of the lower middle end of the processing frame 9. The lower ends of the two guide rods 25 pass through the cross 19 and are slidably connected to the cross 19.

[0036] The folding mechanism 11 is rotated by the rollers 26 on the four sides to prevent the folding mechanism 11 from moving upwards and downwards, and the folding mechanism 11 is rotated by the rollers 26 on the four sides to prevent the folding mechanism 11 from moving upwards and downwards.

[0037] Further, such as Figures 4 to 8 As shown, the pressing assembly includes a piston cylinder 24 fixedly connected to the middle of the processing frame 9, the upper end of the piston cylinder 24 passes through the processing frame 9 and is provided with a suction cup 16, the position of the suction cup 16 is higher than the convex ball 13 on the processing frame 9, the interior of the piston cylinder 24 is hollow, and a piston column 28 is slidably connected to the interior, the lower end of the piston column 28 is fixedly connected to the fixed cylinder 27, the lower end of the piston cylinder 24 passes through the cross 19 and extends into the interior of the fixed cylinder 27, and the piston cylinder 24 is slidably connected to the cross 19 and the fixed cylinder 27. The side of the processing frame 9 away from the conveying mechanism 6 is fixedly connected to the support frame 10, and a multi-stage cylinder 11 is installed on the support frame 10. The multi-stage cylinder 11 is used to push the folded paper shell body 1 to the conveying mechanism 6. The upper end of the conveying mechanism 6 is located on both sides of the conveyor belt and a limit frame 7 is installed to limit the moving path of the paper shell body 1;

[0038] When the paper shell body 1 is placed on the processing frame 9 by the loading and unloading robot arm 8, the middle part of the lower end of the paper shell body 1 will first contact with the suction cup 16, and the suction cup 16 will shrink due to the gravity of the paper shell body 1, and when the lower end of the paper shell body 1 contacts the convex ball 13, it stops shrinking, and then the folding component works. When the folding component works, the output end of the telescopic cylinder 20 will drive the fixed cylinder 27 to move downward, and the downward movement of the fixed cylinder 27 will drive the piston column 28 to move downward inside the piston cylinder 24. Since the upper end of the piston column 28 is tightly fitted inside the piston cylinder 24, after the piston column 28 moves downward, it will drive the gas inside the piston cylinder 24 to move downward, generating suction. Since the lower end of the paper shell body 1 is in contact with the suction cup, the suction cup 16 will shrink. The upper end surface of 16 is in close contact with each other through the action of gravity, so when suction is generated, the suction cup 16 will give the paper shell body 1 a downward force. However, the paper shell body 1 is difficult to move downward due to the blocking effect of the convex ball 13, thereby completing the limiting work of the paper shell body 1. The limiting work is carried out simultaneously with the folding work to ensure that the paper shell body 1 will not shift during folding. When the folding work is completed, the piston column 28 moves upward through the action of the telescopic cylinder 20, releasing the suction generated, that is, canceling the limiting work of the paper shell body 1. Subsequently, the multi-stage cylinder 11 is started to push the folded paper shell onto the conveying mechanism 6, and the paper shell body 1 is conveyed to the next step for gluing and bonding. In this process, the limiting frame 7 plays a limiting role.
