AI Technical Summary

Technical Problem

Existing sealing machines for plastic bag processing are difficult to adjust the spacing of the hot rollers precisely and stably, resulting in inconsistent sealing widths, which affects product quality. Furthermore, they are prone to bag misalignment or jamming during transportation, and the adjustment process is unstable.

Method used

The precise adjustment and synchronous movement of the hot rolling roll spacing are achieved through the linkage between the drive roller, worm gear, transmission rod, worm, slider, connecting block, slide bar, connecting rod, slide plate, first gear, second gear and transport roller, ensuring the consistency of the sealing width and uniform pressure.

Benefits of technology

It enables precise control of the sealing width, preventing spacing changes caused by vibration or external force, improving the consistency and stability of sealing quality, reducing shaking and wrinkles of plastic bags during transportation, and enhancing the equipment's flexible production capacity and effective operating rate.

Abstract

The utility model relates to the technical field of edge sealing machines, and discloses an edge sealing machine for plastic bag processing, which comprises a processing platform, a bearing frame is fixedly connected to the middle of the top of the processing platform, fixing plates are fixedly connected to the two ends of the top of the bearing frame, and a driving roller penetrates through one side between the fixing plates and is rotatably connected to one side between the fixing plates. A worm gear is fixedly connected to one end of the driving roller, a transmission rod penetrates through and is rotationally connected to one side of the fixing plate at one end, a worm is fixedly connected to one end of the transmission rod, the worm is in meshed connection with the worm gear, and a rocker penetrates through and is slidably connected to the other end of the transmission rod; the top of the bearing frame penetrates through and is in sliding connection with sliding blocks which are evenly distributed. According to the plastic bag edge sealing width control device, the requirement for fine control over the plastic bag edge sealing width can be met through linkage among the driving roller, the worm wheel, the transmission rod, the worm, the sliding block, the connecting block, the sliding rod, the connecting rod, the sliding plate, the first gear, the second gear and the conveying roller.
