Packaging bag production involves conveying a variety of raw materials, such as film, paper, and plastic. Different materials place varying demands on the conveyor system. Common conveyor systems include belt conveyors, vibrating conveyors, screw conveyors, and pneumatic conveying systems, each suited to specific material types and characteristics. Design requirements for the feed conveyor system must include high efficiency, stability, and precise control, while also offering strong adaptability and low maintenance costs. Furthermore, with the advancement of automation and intelligent technologies, the feed systems of modern packaging bag production lines are increasingly adopting intelligent control systems and remote monitoring to improve efficiency and stability. Environmental protection and energy conservation are also key design considerations, with approaches such as optimizing drive systems and using environmentally friendly materials contributing to sustainable production. In short, with technological advancements, the feed conveyor system in packaging bag production will evolve towards greater efficiency, intelligence, and environmental friendliness, driving innovation and development across the industry.

[0003] However, existing solutions lack adjustable tension, which can severely impact the stability and efficiency of the infeed conveyor system used in bag production. Improper tension can lead to material breakage, reduced processing precision, and increased equipment wear, increasing production downtime and repair costs. Excessive tension can stretch or tear the material, while insufficient tension can cause it to loosen, sway, or even become stuck. This situation not only wastes raw materials and reduces production efficiency, but also increases energy consumption and manual intervention, impacting product quality and reducing automation levels.

[0004] To this end, the utility model provides a feeding and conveying device for producing packaging bags. Utility Model Content

This helps ensure material stability and prevents material loosening or overstretching, thereby improving production efficiency and product quality. Appropriate tension reduces material loss, protects equipment from excessive wear, and extends its service life. Furthermore, tension adjustment optimizes energy consumption, improves the automation level of the production line, reduces downtime, and enhances production flexibility and stability.

[0014] 2. The feeding and conveying device for packaging bag production described in this utility model converts the impact force generated by external vibrations through the high friction between the piston and the damping cylinder. This friction converts the impact force into heat and dissipates it into the air, thereby damping the vibrations during the raw material conveying process. This can significantly reduce equipment loss and wear, extend equipment life, and improve production stability. Shock absorption helps to smooth material conveying, avoids jamming, deviation, or material damage caused by vibration, thereby ensuring production process continuity and product quality.

[0030] Working principle: When the feeding and conveying device for packaging bag production is running, the external traction equipment first pulls out the raw material. When the tension needs to be adjusted, it is only necessary to pull the gas rod 23 upward with the second limit frame 22 as the stress point through the gas rod 23, and at the same time drive the tensioning cylinder 25 to move synchronously through the slider 24, so as to tension the raw material. At the same time, the second guide roller 31 is pulled by the raw material and rotated upward, thereby compressing the spring 36. After compression, the spring 36 still maintains its original stiffness, that is, the elastic constant of the spring 36, which means that no matter how much the spring 36 is compressed As long as the yield limit of the spring 36 is not exceeded, the hardness or rigidity of the spring 36 will not change, thereby not affecting the tension of the raw material. The vibration generated by the raw material during the transportation process will be transmitted to the first articulated frame 32 and the connecting rod 33 through the second guide roller 31 and the rotating rod 3, thereby driving the piston 34 to slide up and down in the damping cylinder 35. The greater friction between the piston 34 and the damping cylinder 35 converts the impact force generated by the vibration into heat, thereby achieving vibration reduction processing for the vibration received during the transportation of the raw material, and at the same time, the deformation of the spring 36 itself is used for buffering.
