[0002] In today's industrial production, the degree of automation in the product packaging process is crucial for improving production efficiency and reducing labor costs. As a key starting piece of equipment in the packaging production line, the performance of automatic carton openers directly affects the smoothness and efficiency of the overall packaging process. Especially in the rice wine industry, with the growth of market demand and the expansion of production scale, the demand for automatic carton openers that can accurately and quickly process cartons of different specifications is becoming increasingly urgent.

[0003] Existing automatic carton opening machines have many limitations when dealing with diverse carton sizes. Most machines have a fixed storage plate structure, lacking flexibility and making it difficult to adapt to the placement requirements of cartons of different sizes. When the carton size changes, the material feeding space is often too large, causing the carton to be unstable on the storage plate and easily shifting before subsequent processes, affecting opening accuracy and efficiency; or the material feeding space is too small, causing the carton to be unable to be placed smoothly, or even causing damage to the carton, increasing production costs and material waste. To address these issues, we provide a new type of automatic carton opening device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of automatic box opening device.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Please see Figure 1 and Figure 2As shown, this utility model embodiment provides a novel automatic carton opening device. The core component, the support frame 1, is meticulously crafted from high-strength aluminum alloy. Its lightweight and sturdy characteristics ensure stable support for all components while facilitating equipment layout and flexible handling. The outer surface is tightly connected to the storage plate 2 via a precise welding process. The storage plate 2 is made of wear-resistant and impact-resistant engineering plastic with a smooth and delicate surface, effectively reducing frictional wear on the carton and ensuring smooth and unobstructed material feeding with precise positioning. An adjustment mechanism 3 is provided below the storage plate 2. A motor 301 is mounted on the outer surface of the storage plate 2 with a sturdy bolt. The motor 301 is a high-efficiency and energy-saving type, and its output end is strongly connected to the lead screw 302 via a specially made high-strength alloy steel coupling to ensure stable power transmission. The lead screw 302 is precisely screwed to the storage plate 2, and its thread is optimized with a precisely matched pitch, resulting in smooth and unhindered rotation. During driving, the displacement of the moving plate 303 is precisely controlled. The movable plate 303, externally threaded to the lead screw 302, is forged from high-quality carbon steel, making it tough and structurally stable. The movable plate 303 is externally connected to a guide rod 304, which is made of specially treated stainless steel, making it wear-resistant and smooth. Its sliding fit with the storage plate 2 achieves micron-level precision. The distal end of the guide rod 304 is connected to a limiting plate 9, which is integrally molded from engineering plastic and slides against the inner wall of the storage plate 2, limiting the position of the carton and preventing excessive displacement. These three components work together to precisely control the material feeding space of the storage plate 2, adapting to various carton sizes and improving the equipment's versatility. A fixing plate 305 is threadedly connected to the outer surface of the lead screw 302. The outer surface of the fixing plate 305 is fixedly connected to the outer surface of the storage plate 2, providing support for the entire adjustment mechanism 3.

[0025] Please see Figure 3 As shown, a spreading mechanism 5 is provided on the inner side of the support frame 1. Cylinder 1 501 is fixed to the inner wall by a high-strength mounting base, outputting strong power to cylinder 2 502. The inner wall of cylinder 2 502 is tightly slidably fitted with a chrome-plated alloy steel limit rod 503. The outer end of the limit rod 503 is firmly welded to the inner wall of the support frame 1, ensuring that the reciprocating linear motion of cylinder 2 502 is precise, stable, and without any deviation. The mounting plate 504 connected to the output end of cylinder 2 502 is milled from aviation aluminum alloy, which is lightweight, strong, and has excellent rigidity. The suction cups 505 neatly arranged on the mounting plate 504 are made of high-elasticity silicone and are optimized according to fluid dynamics, with strong and uniform adsorption force and rapid response, instantly and firmly adhering to the side of the carton. The push rod 506 connected to cylinder 2 502 is made of hemispherical stainless steel with a smooth surface. It applies precise force from the key support point at the bottom of the carton and works in conjunction with suction cup 505 to perfectly unfold the carton from a folded state into a regular three-dimensional shape with straight edges and flat surfaces. The stable structure is conducive to subsequent processes and improves packaging quality and efficiency.

[0026] Please see Figure 4As shown, a folding mechanism 6 is installed on the inner side of the support frame 1. Motor 601 is fixed to the inner wall of the support frame 1 with precision positioning bolts. Its output end is keyed to a high-quality alloy steel rotating shaft 602. The rotating shaft 602 rotates smoothly with the support frame 1 via high-precision bearings, ensuring stable operation, low noise, and a long service life. The folding plate 603 connected to the rotating shaft 602 is made of engineering plastic injection molding followed by surface hardening treatment, exhibiting excellent flexibility and wear resistance, precisely guiding the folding of the carton lid. The drive gear 604 and driven gear 605 on the rotating shaft 602 are precision machined and heat-treated from high-strength alloy steel, ensuring tight and precise meshing, efficient and reliable transmission, and superior load-bearing capacity. The rotating shaft 606 driven by the driven gear 605 rotates stably with the support frame 1 via high-quality bearings. The externally connected folding plate 607 works in conjunction with folding plate 603, precisely maneuvering according to the carton lid folding process, tightly and precisely folding the lid, improving packaging sealing and aesthetics, and enhancing the equipment's core competitiveness in the rice wine packaging line.

[0027] In this embodiment, a mounting frame 7 is welded to the outer surface of the support frame 1. The mounting frame 7 is made of high-strength steel, with a stable structure and excellent shock resistance, providing support for the conveyor belt 8. The conveyor belt 8 is composed of a wear-resistant rubber surface layer and a high-strength polyester fiber core layer. The surface texture is designed according to the principle of tribology, with moderate and stable friction, ensuring close connection and efficient and smooth operation of each process. This achieves stable and reliable operation of the entire automatic box opening process, significantly improving the automation level and production efficiency of rice wine packaging.

[0028] The specific working principle of this utility model is as follows: During operation, motor 301 is activated according to the size of the carton. Motor 301 drives screw 302 to rotate. Under the coordinated guidance of guide rod 304 and limiting plate 9, moving plate 303 can drive guide rod 304 and limiting plate 9 to move laterally horizontally, causing the two limiting plates 9 to move closer or further apart, changing the material feeding space in storage plate 2 to fit the carton. After the carton is placed on storage plate 2, storage push plate 4 pushes it to the working area of ​​opening mechanism 5. At this time, cylinder 2 502 starts along the limit rod 503 and pushes the mounting plate 504 and suction cup 505 forward smoothly. The mounting plate 504 and suction cup 505 precisely adhere to the side of the carton and adhere to it. Then, the telescopic end of cylinder 2 502 drives the mounting plate 504 and suction cup 505 to retract backward. At the same time, the top rod 506 can smoothly unfold the side panels of the carton from the folded state during the adsorption and movement process, so that the edges are straight, the surfaces are flat, and there is no damage or deformation. Then, motor 2 601 is turned on. Motor 601 drives shaft 602 and drive gear 604 to rotate. At this time, shaft 602 drives folding plate 603 to rotate clockwise, and drive gear 604 drives driven gear 605, shaft 606 and folding plate 607 to rotate counterclockwise. Through the cooperation of folding plate 603 and folding plate 607, the bottom cover of the carton can be folded accurately, completing the entire automatic opening process. Then cylinder 501 is started, and its telescopic end drives cylinder 502, mounting plate 504, suction cup 505 and push rod 507. 06 moves towards the conveyor belt 8. During the process, the limit rod 503 can guide and limit it to avoid deviation of the movement trajectory. At this time, the carton moves onto the conveyor belt 8 on the vertical folding plate 1 603 and folding plate 2 607. Then, the suction cup 505 releases the suction of the carton, so that the carton can be smoothly conveyed from the conveyor belt 8 to the top of the tape applicator to achieve the sealing operation of the bottom of the carton. Through the cooperation of various mechanisms, the carton can be opened quickly, which improves the overall operation efficiency.
