Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a dual-push device based on a cam assembly and a single power source. Background Technology

[0002] In the tissue packaging production process, the material feeding mechanism is one of the core functional components. It is mainly responsible for separating and conveying the tissue raw materials or packaging semi-finished products to be packaged one by one to the subsequent processes such as folding, sealing, and cutting. Its operational stability and adaptability directly affect the production efficiency and product quality of the entire production line. Currently, the material feeding mechanisms used in tissue packaging production lines on the market generally have an oversized overall size. From a practical application perspective, the excessive size will cause the mechanism to occupy too much space in the production workshop. Especially when the production line layout is relatively compact, or when it needs to work in coordination with other equipment such as folding machines, sealing machines, and conveyor rollers, it is difficult to achieve efficient space matching and connection between the various devices. This not only increases the difficulty of overall production line layout planning, but may also obstruct the material transmission path due to unreasonable spacing between devices, thereby affecting the continuity of the production process. At the same time, existing material handling mechanisms are often bulky due to their large size. On the one hand, during the manufacturing stage, the bulky structure requires more raw materials and more complex processing technology, which directly leads to a significant increase in the manufacturing cost of the mechanism. On the other hand, during equipment installation, commissioning, daily operation and maintenance and later repair, the bulky structure requires more manpower and material resources, which not only increases the difficulty of operation, but also further increases the cost of using and maintaining the equipment. In summary, the existing material feeding mechanisms suffer from deficiencies in size, structure, and cost, making them unable to adapt well to the diverse needs of current tissue packaging production lines. This makes it difficult to achieve a balance between production efficiency and cost control, ultimately failing to achieve optimal performance. To a certain extent, this also restricts the development of the tissue packaging production industry towards higher efficiency and lower costs. Utility Model Content

[0026] As a preferred embodiment of this utility model, the operating principle of this device is as follows: This device is typically installed above the production line conveying tissues to be packaged; the drive motor 1 operates, driving the first output shaft 3 and the second output shaft to rotate simultaneously; the rotation of the first output shaft 3 drives the first swing arm 6 to rotate, the rotation of the first swing arm 6 drives the first pulley 8 to move along the first slide rail 10, thereby driving the first slider 9 to move along the first slide rail 10, the first slider 9 drives the first Z-axis slide rail 12 to move vertically, the first Z-axis slide rail 12 drives the first linkage slider 13 to move horizontally along the first X-axis slide rail 11, ultimately realizing the first slider 9 to perform a circular motion along the first slide rail 10. A Z-axis slide rail 12 and a first linkage slider 13 work together to drive the first push rod 16 connected to it to perform a circular motion in a vertical state with the first output shaft 3 as the rotation axis and a rounded rectangle as the trajectory. This motion moves the tissues to be packaged on the production line below, transferring them to another production line and completing the material flow of the production line. Similarly, the second cam mechanism moves with the same motion principle, causing the second push rod 20 to follow the first push rod 16 and perform a corresponding material-grabbing action. The rounded rectangle slide trajectory allows the push rod to have a longer stroke than the circular slide trajectory with the same center, and at the same time, it can make the device smaller in size for the same stroke.
