AI Technical Summary

Technical Problem

Traditional packaging film pressing devices are difficult to adapt to film materials of different thicknesses and require manual adjustment, resulting in low production efficiency and poor pressing effect. In particular, the synchronous adjustment of dual pressure rollers makes it difficult to ensure parallelism and pressure consistency.

Method used

The piston rod is extended and retracted by a servo electric cylinder, and the height of the first pressure roller is adjusted by the linkage rotating frame. The second pressure roller is adjusted synchronously by the connecting plate to achieve automatic adjustment of the pressure. The height of the second pressure roller is finely adjusted by the threaded part and the fixing part to ensure the consistency of the pressure roller gap.

Benefits of technology

It achieves automatic adjustment of the clamping degree to adapt to different membrane thicknesses, avoids membrane wrinkles or damage, and improves production efficiency and clamping effect.

Abstract

This utility model relates to the field of packaging film processing, and in particular to a packaging film pressing device, including a mounting frame, on which a pressing mechanism is provided. The pressing mechanism includes two pairs of symmetrically arranged rotating brackets on the mounting frame, and an active roller is rotatably arranged at the bottom between the two pairs of rotating brackets. This utility model uses a servo electric cylinder to control the extension and retraction of the piston rod, which links the first rotating bracket to adjust the height of the first pressing roller, achieving automatic adjustment without manual intervention. It adapts to film materials of different thicknesses and makes adjusting the pressing degree more convenient. The connecting plate synchronously pulls the fixing plate and the second pressing roller to ensure that the gap between the two pressing rollers and the active roller changes synchronously, avoiding wrinkles or damage to the film material caused by uneven pressure. The adjusting rod of the second pressing roller is equipped with a threaded part and a fixing component, which can be individually fine-tuned to meet the differentiated pressing requirements of special film materials and improve process adaptability.
