AI Technical Summary

Technical Problem

Existing insulated box packaging equipment has a complex structure and low efficiency. Furthermore, the insulated layer conveying system is prone to disorder during power outages, requiring readjustment upon startup and impacting production efficiency.

Method used

A braking-type lubricating film feeding device is adopted. Through the brake and power failure braking protection device, the cylinder, spring and brake block realize automatic braking when the power is cut off, to prevent the gravity roller assembly from falling and ensure the orderly delivery of the lubricating film.

Benefits of technology

In the event of a power outage, this prevents the insulating film from becoming disordered, improves production efficiency and equipment stability, and avoids conveying problems caused by power outages.

Abstract

This utility model discloses a braking-type insulating film feeding device for insulating box packaging equipment, including a roller connected to a main wall plate. The roller is rotatably connected to the main wall plate, and a film disc is fixedly connected to the roller. Several guide rollers are provided on the main wall plate, and a gravity roller assembly is also included. The gravity roller assembly is slidably connected to the main wall plate. The insulating film layer passes through the guide rollers and the gravity roller assembly and is pulled forward. A brake is connected to the rear end of the roller. The brake is connected to a power failure braking protection device. A brake start / stop sensor is provided on the side of the gravity roller assembly, and the brake start / stop is controlled by the brake start / stop sensor. This application is equipped with a power failure protection device. When the power is off, there is no gas in the cylinder. At this time, the piston rod of the cylinder presses the brake block against the brake under the action of the spring, thereby achieving braking. Then the gravity roller assembly cannot fall, so as not to cause the insulating film to become disordered when the gravity roller assembly falls due to power failure.
