Automatic labeling machine height adjusting device

Abstract

The invention relates to the field of packaging machinery, in particular to an automatic labeling machine height adjusting device which is simple in structure, convenient to use and suitable for softpackage products with inconsistent bulking heights. The device comprises a rack, a first belt conveying device, a support and a labeling machine; the first belt conveying device, the support and the labeling machine are arranged on the rack; a second belt conveying device is arranged on the support; the conveying direction of the second belt conveying device is the same as that of the first belt conveying device; the labeling machine is arranged on the support and located at the output end of the second belt conveying device; the support is arranged on the upper side of the first belt conveying device and hinged to the rack; vertical swing of the output end of the second belt conveying device is achieved; and a spring is arranged between the end, away from the hinged point of the support and the rack, of the support and the rack, and when the first belt conveying device is in a shutdown state, the vertical distance between the input end of the second belt conveying device and the firstbelt conveying device is larger than the vertical distance between the output end of the second belt conveying device and the first belt conveying device.

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] The labeling machine is widely used in the packaging field, and is a device for pasting paper or metal foil labels on packaging containers through adhesives. Existing labeling machine structure, such as the labeling mechanism of the adhesive tape automatic labeling machine disclosed in Chinese patent application number: 201620594021.5, it sets the labeling machine on the upper side of the conveyor belt, so that the products with packing boxes are placed in the The conveyor belt conveys 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 a slider assembly is set to manually adjust the height of the labeling machine to use products of different sizes; but the The height adjustment of this labelin...

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
