Steam shrinking device

Abstract

The invention discloses a steam label shrinking device capable of greatly reducing energy consumption. The steam label shrinking device comprises a conveyer belt, wherein a mounting rack is arranged at the outer side of the conveyer belt, a label shrinking cylinder is arranged on a top plate of the mounting rack, a label shrinking piston rod is downwards vertical and is fixedly connected with a cover body, the cover body comprises a tubular body, a top cover is arranged on the top of the tubular body, the tubular body and the top cover form a containing cavity with a downward opening, the tubular body is hollow and forms a steam containing cavity, a plurality of through holes are formed in the inner wall of the tubular body, a steam conveying pipe communicated with the steam containing cavity and provided with a control valve is connected onto the cover body, a retaining device on the mounting rack can retain a water barrel right below the cover body, at the moment, the label shrinking cylinder drives the cover body to move downwards until the opening of the water barrel is contained in the containing cavity of the cover body, and after the label shrinking cylinder drives the cover body and the water barrel to be separated from each other, the retaining device does not retain the water barrel and the water barrel is continuously conveyed through the conveyer belt.

Description

technical field [0001] The invention relates to a bottled water packaging production line, in particular to a steam shrink labeling device. Background technique [0002] In the bottled water packaging production line, the label on the mouth of the bucket needs to be shrinked by the steam shrinking device. The structure of the traditional steam shrinking device includes: a conveyor belt, a mounting frame is arranged on the outside of the conveyor belt, and an inverted U-shaped channel opening downward is installed on the mounting frame above the conveyor belt. A steam storage chamber is formed, and the steam delivery pipe connected with the steam storage chamber is connected to the tank body, and several through holes are opened on the inner side walls of both sides of the inverted U-shaped channel; the installation height of the inverted U-shaped channel is the same as the height of the bucket It is suitable and can ensure that the mouth of the bucket on the conveyor belt b...

AI Technical Summary

Problems solved by technology

The defect of the above-mentioned steam shrinking device is that: the length of the inverted U-shaped channel is relatively long. In order to transport the bucket, the two ends of the inverted U-shaped channel are opened and not closed, and the steam needs to be continuously ejected during work, so the steam consumption is very high. large, high energy consumption
