Description

Technical Field

[0001] This utility model relates to the field of cartoning machine transmission technology, and in particular to a dynamic balance and stabilization device for a cartoning machine transmission system. Background Technology

[0002] In the field of modern automated packaging, cartoning machines are key equipment for the automated packaging of pharmaceuticals, food, and daily necessities. The performance of their transmission systems directly affects the packaging quality and production efficiency. The dynamic balance and stability of the transmission system is not only related to the operational reliability of the equipment, but also a core element in ensuring the continuity, accuracy, and safety of cartoning operations. Therefore, developing a highly efficient and reliable dynamic balance stabilization device for the transmission system of cartoning machines has significant practical implications.

[0003] Currently, most cartoning machine transmission systems primarily use traditional chain drive mechanisms for power transmission. This traditional chain drive structure typically relies on fixedly installed sprockets, chains, and simple tension adjustment components. During operation, the chain tension is set once through mechanical limits or basic bolt adjustments to ensure that the chain maintains basic tension during transmission, thereby completing a series of operations such as material conveying, carton forming, and product loading.

[0004] However, due to varying operating conditions such as differences in material weight and production speed, the traditional fixed or extensive tension adjustment methods of existing cartoning machine chain drive mechanisms cannot meet the dynamic tension requirements of the chain drive mechanism. When the chain tension is insufficient, problems such as chain slippage and tooth skipping can easily occur, leading to a decrease in transmission efficiency and even causing malfunctions such as misalignment and jamming in cartoning. On the other hand, excessive tension will increase the wear of the chain and sprockets, shorten the service life of the equipment, and also increase energy consumption, seriously affecting the stable and efficient operation of the cartoning machine. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 4 An embodiment of this utility model provides a dynamic balancing and stabilizing device for a cartoning machine transmission system, comprising a chain body 1, a fixed frame 3 provided on one side of the outer wall of the chain body 1, an inner plate 5 fixedly connected inside the fixed frame 3, a sprocket 2 rotatably connected inside the inner plate 5, the sprocket 2 meshing with the chain body 1, a push plate 4 rotatably connected to the outer wall of the sprocket 2, a connecting plate 6 fixedly connected to the inner wall of the push plate 4, a push rod 7 fixedly connected to one side of the connecting plate 6, and an adjustment component provided at one end of the push rod 7;

[0027] The adjustment assembly includes a triangular slide plate 8 and a second push plate 10. The outer wall of the triangular slide plate 8 is fixedly connected to one end of the push rod 7. A T-shaped slide plate 18 is fixedly connected to one side of the outer wall of the triangular slide plate 8. A fixed plate 12 is fixedly connected to the outer wall of the inner plate 5. A handwheel 11 is rotatably connected inside the fixed plate 12. A telescopic rod 17 is fixedly connected to one end of the handwheel 11. A threaded rod 9 is fixedly connected to one end of the telescopic rod 17. The inner thread of the second push plate 10 is threadedly connected to the outer wall of the threaded rod 9. The inner wall of the second push plate 10 is slidably connected to the outer wall of the triangular slide plate 8. The second push plate 10 is used to drive the triangular slide plate 8 to move. The outer wall of the triangular slide plate 8 is slidably connected to the inside of the inner plate 5. The triangular slide plate 8 is used to drive the first push plate 4 to move.

[0028] Specifically, in use, the drive handwheel 11 rotates, its stable structure efficiently transmitting power, causing the high-strength alloy telescopic rod 17 and the internal threaded rod 9 to rotate synchronously. The threaded rod 9 and the push plate 10 are connected by a high-precision thread, causing the push plate 10 to move axially during rotation. The inclined surface at the front end of the push plate 10 pushes the triangular slide plate 8 to slide along the track of the inner plate 5, changing the direction of force transmission. This causes the connecting plate 6 to shift via the push rod 7, thereby driving the push plate 4 and the sprocket 2 to move synchronously, achieving precise adjustment of the tension of the chain drive mechanism.

[0029] Reference Figure 1 , Figure 4 and Figure 5A limiting wheel 13 is fixedly connected to the outer wall of the handwheel 11. A fixing ring 14 is fixedly connected to the outer wall of the telescopic rod 17 near the handwheel 11. A reset assembly is provided on the outer wall of the telescopic rod 17. The reset assembly includes a movable ring 15 and a spring 16. The movable ring 15 and the spring 16 are both sleeved on the outer wall of the telescopic rod 17. One end of the spring 16 is fixedly connected to the outer wall of the movable ring 15, and the other end of the spring 16 is fixedly connected to the outer wall of the fixing ring 14. The fixing ring 14 and the movable ring 15 are slidably connected inside the fixing plate 12. The fixing ring 14 and the movable ring 15 are used to drive the spring 16 to extend and retract. The outer wall of the limiting wheel 13 is slidably connected inside the fixing frame 3. The limiting wheel 13 is used to limit the handwheel 11.

[0030] Specifically, pulling the handwheel 11 outward causes the coaxial limit wheel 13 to slide within the fixed frame 3. After disengaging from the limit, it can be freely adjusted. During the movement, the telescopic rod 17 stretches, causing the spring 16 to store energy. After adjustment, the spring rebounds, causing the limit wheel 13 to reset, thus firmly limiting the handwheel 11, preventing loosening during operation, and ensuring stable and reliable tension adjustment.

[0031] Working Principle: When the adjustable tension chain drive is needed, the handwheel 11 is first driven to apply rotational force. Thanks to its robust structural design, the handwheel 11 efficiently transmits the operator's power, causing the closely connected telescopic rod 17 to rotate. The telescopic rod 17 is made of high-strength alloy material, possessing excellent torsional resistance and maintaining stability during rotation. Simultaneously, it drives the internally nested threaded rod 9 to rotate synchronously. The surface of the threaded rod 9 undergoes high-precision thread machining, precisely matching the internal threaded hole of the push plate 10. As the threaded rod 9 rotates, according to the threaded transmission principle, the push plate 10 moves linearly along the axial direction under the action of the threaded rod 9. The front end of the push plate 10 is carefully designed with specific... The inclined plane, when moving linearly, will fit closely with the side of the triangular slide plate 8, and the pushing action of the inclined plane will drive the triangular slide plate 8 to slide smoothly along the pre-designed track inside the inner plate 5. The triangular slide plate 8 has a unique shape, and its sliding process can effectively change the direction of force transmission. Through the push rod 7 connected to it, the force is accurately transmitted to the connecting plate 6. The connecting plate 6 has a sturdy structure and can withstand a large tensile force. Under the action of the push rod 7, it will be displaced, and then, through its connection structure with the push plate 4 and the sprocket 2, it will drive the push plate 4 and the sprocket 2 to move synchronously. The movement of the sprocket 2 ultimately realizes the precise adjustment of the tension of the rubber-coated chain drive mechanism, meeting the requirements of the chain drive mechanism for tension under different working conditions.

[0032] Furthermore, when the handwheel 11 is pulled outward, its exterior features a textured surface for easy gripping, facilitating force application by the operator. As the handwheel 11 moves outward, the limiting wheel 13, coaxially mounted with it, slides within the fixing frame 3. The inner surface of the fixing frame 3 is finely polished to ensure smooth and stable sliding of the limiting wheel 13. When the limiting wheel 13 completely disengages from the fixing frame 3 under external force, the handwheel 11 is freed from its limiting constraint, allowing the operator to freely drive it to rotate and initiate the subsequent tension adjustment process. During the movement of the handwheel 11, the connected telescopic rod 17 is also stretched accordingly. The telescopic rod 17 consists of multiple nestable telescopic tubes, providing excellent extension... With the telescopic rod 17 moving, the fixed ring 14 at its end and one end of the spring 16 connected to the fixed ring 14 are also moved, causing the spring 16 to gradually stretch and store elastic potential energy. After the tension adjustment operation is completed, the spring 16 begins to rebound with its stored elastic potential energy. This rebound force is transmitted to the telescopic rod 17 through the fixed ring 14, which in turn drives the limit wheel 13 to slide along the internal track of the fixed frame 3 again until it returns to the initial limit position inside the fixed frame 3, thus achieving a firm limit on the handwheel 11. This effectively prevents the handwheel 11 from loosening due to vibration or other external forces during equipment operation, ensuring the stability and reliability of the tension adjustment of the chain drive device.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
