An automatic height adjustment device for a labeling machine

Abstract

The invention relates to the field of packaging machinery, in particular to an automatic height adjustment device for a labeling machine that is simple in structure, convenient to use and suitable for soft package products with inconsistent bulk heights, comprising a frame and a first belt arranged on the frame Conveying device, bracket, labeling machine, the bracket is provided with a second belt conveying device, the conveying direction of the second belt conveying device is the same as the conveying direction of the first belt conveying device, the labeling machine is arranged on the bracket and located on the second belt At the output end of the conveying device, the bracket is arranged on the upper side of the first belt conveying device and is hinged with the frame to realize the up and down swing of the output end of the second belt conveying device. There is a spring between the two belt conveyors. When the first belt conveyor is in the shutdown state, the vertical distance between the input end of the second belt conveyor and the first belt conveyor is greater than the distance between the output end of the second belt conveyor and the first belt conveyor. vertical distance.

Description

technical field [0001] The invention relates to the field of packaging machinery, in particular to an automatic height adjustment device for a labeling machine. Background technique [0002] Labeling machine is widely used in the field of packaging, and it is a device that sticks paper or metal foil labels on packaging containers through adhesives. The structure of the existing labeling machine, such as the labeling mechanism of the adhesive tape automatic labeling machine disclosed in China Patent Application No. 201620594021.5, which sets the labeling machine on the upper side of the conveyor belt, so that the products with packaging boxes are The conveyor belt is conveyed through the channel formed by the labeling machine and the conveyor belt. The label on the labeling machine is attached to the packaging box, and the slider assembly is set to manually adjust the height of the labeling machine, and products of different sizes are used; but this The height adjustment of ...

Problems solved by technology

In tens of seconds without being pinched, the fluff pulp will automatically expand, from 5mm to 6mm in a single piece, to 7mm to 8mm in a single piece after 30 seconds, and the packaging bag usually stores 10 pieces, resulting in an increase of 10mm to 30mm , In this way, the packaged products cannot pass through the channel formed by the labeling machine and the conveyor belt, causing blockage; at the same time, the products are on the production line for different lengths of time, and the product bulk height is inconsistent, which cannot be adjusted through the slider assembly. Even if it can pass, Because of the inconsistent bulk height, the resistance through the labeling machine is different, causing the label to be skewed and unqualified

[0005] Using another labeling machine, such as the labeling robot, labeling machine and labeling method disclosed in Chinese Patent Application No. 201511034922.5, the spider hand robot is set on the conveyor belt for labeling, which can be more suitable for Labeling of products with different bulkiness, but on products with inconsistent bulkiness heights on the same package, the spider hand robot sticks vertically downwards, and the force is uneven, which is likely to cause skewing or even falling during transportation, and the structure is complex , which is expensive and greatly increases the cost
