AI Technical Summary

Technical Problem

Traditional bubble wrap feeding devices often experience loosening and wrinkling of the bubble wrap in the later stages of feeding due to insufficient clamping force, which affects production efficiency and product quality.

Method used

A bubble wrap feeding device was designed. Through the cooperation of the transmission component, the pushing component and the elastic component, the pressure roller descends synchronously with the feeding roller to maintain a suitable pressure on the bubble wrap. A multi-stage transmission structure and sensors are used to adjust the feeding speed.

Benefits of technology

It effectively prevents the bubble wrap from loosening and wrinkling, improves the stability of feeding, ensures smooth production, and enhances the tension and production efficiency of the bubble wrap.

Abstract

The application discloses a bubble film feeding device for bubble bag production and relates to the technical field of bubble bag production. The device comprises a support, a feeding roller installed on the support, a pressing roller, an elastic assembly, a pushing assembly and a transmission assembly. The pressing roller is arranged on the inner side of the upper part of the support, and the elastic assembly is arranged on the inner wall of the upper part of the support and connected with the pressing roller. The pushing assembly is arranged on the side wall of the support. The transmission assembly is connected with the roller shaft end of the feeding roller. When the feeding roller is driven to rotate and feed, the transmission assembly is driven to rotate by the roller shaft end of the feeding roller and drives the pushing assembly to move horizontally. The elastic assembly is fixed with an inclined plate, and the pushing assembly is matched with the inclined plate on the elastic assembly through abutting, so that the elastic assembly is compressed, the pressing roller descends synchronously with the rotation and feeding of the feeding roller, the appropriate pressing force on the bubble film is maintained, the bubble film always maintains the appropriate tension during the feeding process, and the loosening and wrinkling condition during feeding is effectively avoided.
