Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of boxing equipment, especially small plug ear boxing machine. BACKGROUND

[0002] In modern industrial production, boxing equipment is widely used in the packaging process of various products, especially in production lines that require high efficiency and automation. Its role is particularly important. Traditional boxing machines can usually complete the forming of paper boxes, product filling, and basic packaging of box bodies, etc. However, there are still deficiencies in the packaging process of some paper boxes with special structures. For example, when packaging paper boxes with small plug ears, accurate folding and locking insertion operations need to be performed on the small plug ears to ensure the sealing of the box body and the safety of the product. However, existing boxing equipment often fails to achieve accurate folding and locking insertion of small plug ears when processing such paper boxes, resulting in unsatisfactory packaging results, and even the problem of product falling or box body loosening. In addition, existing equipment usually lacks flexible adjustment function and cannot adapt to paper boxes of different sizes and specifications, limiting its application range. At the same time, the layout of the functional modules of the traditional boxing machine is not optimized, resulting in low production efficiency and difficulty in meeting the requirements of modern industry for high efficiency and high precision. Therefore, developing a boxing machine that can efficiently complete the folding and locking insertion operations of small plug ears and optimizing the functional layout and adjustment capability of the equipment has become a technical problem to be solved. The utility model is aimed at the above problems and proposes an innovative small plug ear boxing machine to improve packaging quality, enhance equipment adaptability and improve overall production efficiency.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] The present application will now be described in detail with reference to the drawings illustrating the embodiments thereof:

[0026] In conjunction with Figures 1 to 5 The concrete embodiments of the present application are described in detail. As Figure 2 and Figure 3As shown, the overall structure of the small-ear carton filling machine includes a frame, a carton feeding mechanism 4, a product feeding mechanism 5, a bottom sealing mechanism 8, a top sealing mechanism 6, a locking mechanism 7, and a conveying mechanism. The frame serves as the basic support structure for the equipment, used to install and fix each functional mechanism. The carton feeding mechanism 4 is mounted above the conveying mechanism, its function being to place cardboard between the forming bars on the conveying mechanism to complete the initial forming of the carton. The product feeding mechanism 5 is located on one side of the conveying mechanism, used to push the product to be filled into the carton. The bottom sealing mechanism 8 is located on the other side of the conveying mechanism, responsible for sealing the bottom of the carton. The top sealing mechanism 6 is located on the same side as the product feeding mechanism 5, used for sealing the side wings and front flap of the carton. The conveying mechanism runs through the entire equipment, responsible for sequentially conveying the carton to each functional mechanism, thus completing the entire process from feeding and sealing to final locking assembly.

[0027] The locking mechanism 7 is the core component of this utility model, and its structural design and operating principle are particularly important. Combined with... Figure 4 and Figure 5 As can be seen, the locking mechanism 7 includes an insert 15, a folding push plate 16, a stop pin 18, a lifting frame 10, an extension plate 11, a positioning frame 12, and a small insert ear lifting rod 9. The insert 15 is a thin sheet structure, driven by the second cylinder 14 to move vertically. When the insert 15 descends, its front end contacts the latch 2 at the end of the small insert ear 3, inserting the latch 2 into the insert cover, thus completing the final sealing operation. The folding push plate 16 is an L-shaped structure, driven by the first cylinder 13 to move vertically. When the folding push plate 16 descends, its inner surface contacts the small insert ear 3 and applies pressure, realizing the pressing and folding action of the small insert ear 3. The stop pin 18 is driven by the horizontal cylinder 17 to move horizontally. When the stop pin 18 extends, its end contacts the small insert ear 3 and tilts the small insert ear 3 forward at a certain angle to facilitate the subsequent folding operation of the insert 15. The lifting frame 10 is equipped with a positioning frame 12 and an extension plate 11, and is fixed to the machine frame via a height-adjustable connection. By adjusting the height of the lifting frame 10, the locking mechanism 7 can adapt to different sizes of cardboard boxes, improving the versatility and applicability of the equipment. One end of the small insert ear lifting rod 9 is provided with an upward tilting structure. When the lifting rod 9 rises, its tilted end contacts the small insert ear 3 and flips the small insert ear 3 up, facilitating the box top sealing mechanism 6 to perform preliminary sealing operations on the box top.

[0028] The working process of the small tab box packing machine includes the following steps: S1, the paper box feeding mechanism 4 places the paperboard between the forming grooves on the conveying mechanism to complete the preliminary forming of the paper box; S2, the conveying mechanism conveys the preliminarily formed paper box to the box bottom packaging mechanism 8, and the box bottom packaging mechanism 8 packages the box bottom; S3, the conveying mechanism conveys the paper box with the packaged box bottom to the product feeding mechanism 5, and the product feeding mechanism 5 pushes the product into the paper box; S4, the conveying mechanism conveys the paper box filled with the product to the box top packaging mechanism 6, and the box top packaging mechanism 6 packages the side wings and the positive wing cover of the box top; S5, the conveying mechanism conveys the paper box to the lock catch mechanism 7, and the lock catch mechanism 7 completes the folding and lock catch assembly of the small tab 3. In S5, the specific operation steps of the lock catch mechanism 7 are as follows: first, the small tab lifting rod 9 rises, the raised end thereof contacts the small tab 3 and flips up the small tab 3; second, the blocking pin 18 extends, the end thereof contacts the small tab 3 and tilts the small tab 3 by a certain angle; third, the insert piece 15 descends, the front end thereof contacts the lock catch 2 at the end of the small tab 3 and inserts the lock catch 2 into the insert cover; finally, the folding push plate 16 descends, the inner side surface thereof contacts the small tab 3 and applies pressure to the small tab 3 to complete the pressing and folding of the small tab 3.

[0029] In the above working process, the operation of the paper box feeding mechanism 4 is particularly critical. When the paper box feeding mechanism 4 places the paperboard between the forming grooves on the conveying mechanism, it needs to ensure that the edges of the paperboard are tightly fitted with the forming grooves to avoid the paper box from being offset or misaligned in the subsequent process. The feeding speed of the paper box feeding mechanism 4 needs to match the speed of the conveying mechanism to ensure that the paper box can be accurately conveyed to the next station within the specified time. The product feeding mechanism 5 uses a pushing device to load the product into the paper box. The pushing device is composed of multiple cylinders and can adjust the pushing force and stroke according to the size and shape of the product to ensure that the product can smoothly enter the paper box without damaging the paper box. The box bottom packaging mechanism 8 performs packaging operation on the bottom of the paper box through hot melt adhesive or other bonding technology, and the temperature and time parameters need to be strictly controlled during the packaging process to ensure that the packaging part has sufficient strength and sealing performance. The box top packaging mechanism 6 performs packaging operation on the side wings and positive wing cover of the top of the paper box, and the mechanical arm is used to fold and press the side wings and positive wing cover during the packaging process to make the packaging part flat and firm.

[0030] The design of the locking mechanism 7 embodies the technical innovation point of the utility model. In actual operation, the first cylinder 13 and the second cylinder 14 drive the folding push plate 16 and the insert piece 15 to move along the vertical direction respectively, realizing accurate pressing of the small insert ear 3 and precise insertion of the lock catch 2. The horizontal cylinder 17 drives the blocking pin 18 to move horizontally along the horizontal direction, which can effectively adjust the angle of the small insert ear 3, providing convenient conditions for subsequent operation. The height-adjustable design of the lifting frame 10 enables the equipment to adapt to paper boxes of different specifications, expanding the application range of the equipment. The clever design of the raised end of the small insert ear jacking rod 9 enables the small insert ear 3 to be easily turned up during the jacking process, reducing errors in the operation process. In addition, the components of the locking mechanism 7 work cooperatively through precise matching relationship, significantly improving the overall operation efficiency and packaging quality of the equipment.

[0031] In order to further improve the production efficiency and packaging precision of the equipment, the utility model also optimizes the matching relationship between each mechanism. For example, the conveying mechanism not only conveys the paper boxes to each functional mechanism in turn, but also sets a buffer area between each station to avoid the collision or dumping of the paper boxes due to too fast conveying speed. In addition, each functional mechanism is equipped with a sensor and a control system, which can monitor the position and state of the paper box in real time, and automatically adjust the operation parameters according to the detection results, ensuring that each operation can be completed smoothly. For the folding of the small insert ear 3 and the assembly of the lock catch 2, the utility model adopts multi-stage linkage control technology, which realizes high-precision folding of the small insert ear 3 and precise insertion of the lock catch 2 through the coordinated action of multiple cylinders. After the small insert ear 3 is pressed and folded by the folding push plate 16, the blocking pin 18 is reset immediately, and then the insert piece 15 moves downward to insert the lock catch 2 into the box body to complete the packaging of the lock catch 2. This multi-stage linkage control technology not only improves the stability of the operation, but also significantly reduces the failure rate of the equipment.

[0032] The practical application scenarios of the utility model cover multiple industry fields such as food, medicine, daily chemical industry, etc. In the food industry, the small insert ear box packing machine can be used for automatic packaging of biscuit, candy and other products, improving the production efficiency while ensuring that the packaging quality meets the food safety standards. In the pharmaceutical industry, the equipment can be used for the outer packaging of medicines, ensuring that the medicines will not be contaminated or damaged during transportation and storage. In the daily chemical industry, the equipment can be used for packaging of cosmetics, washing products and other products, meeting the market demand for high-quality packaging. No matter in which application scenario, the utility model can realize efficient and accurate operation of folding the small insert ear 3 and assembling the lock catch 2 through optimized structure design and multi-mechanism cooperative work, significantly improving the production efficiency and ensuring the product quality.

[0033] In summary, the utility model discloses through optimizing structure design and multiple mechanism collaborative work, solved the low production efficiency, the problem of poor packaging precision in the prior art. The lock catch mechanism 7 adopts the cylinder drive's insert piece 15 and the folding push plate 16, through the accurate control small insert ear 3's folding and the operation of lock catch 2, has improved the packaging quality significantly. The height adjustable design of lifting frame 10 makes the equipment can adapt to different specifications carton, has improved the versatility and the scope of application of equipment. Small insert ear top lift column 9 and the design of the blocking pin 18 effectively reduce the error in the operation process, ensure the stability of small insert ear 3 folding and lock catch 2 assembly. In addition, the close cooperation between each mechanism and the efficient operation of the conveying mechanism, significantly improve the overall production efficiency. These improvements and adjustments should be considered as the protection scope of the utility model, therefore the protection scope of the utility model patent should be the attached claims.
