A pressing device applied to a labeling machine

Abstract

The invention discloses a press covering device applied to a labeling machine. A left supporting seat and a right supporting seat are fixed at two sides of a supporting plate of the press covering device respectively; a horizontal spreading roll and a press roll are arranged between the left supporting seat and the right supporting seat; two ends of the spreading roll or the press roll are both hinged on a side bracket, and the side bracket is fixed on the supporting plate; a turntable is hinged on the inner wall of the left supporting seat; a sleeve body is formed on the outer wall of the right supporting seat; a slide block is inserted into the sleeve body; a horizontal push cylinder is fixed on the outer side wall of the sleeve body; a piston rod of the push cylinder penetrates through the sleeve body and is fixed on the slide block; a clamped cylinder is fixed on the slide block; a stud is formed at the top of a piston rod of the clamped cylinder; a pipe sleeve sleeves on the piston rod of the clamped cylinder by inserting; an end cap sleeves on the piston rod of the clamped cylinder at the front end of the pipe sleeve by inserting; a nut is in threaded connection with the stud at the front side of the end cap; and the end cap presses against the nut. The press covering device disclosed by the invention is simple in structure, can be used for performing press fit treatment on a label on a bottle body, and can eliminate a condition of edge warping of the label during labeling, thereby ensuring the labeling quality of the labeling machine.

Description

Technical field: [0001] The invention relates to the technical field of automatic labeling machines, and more specifically relates to a pressing device applied to a labeling machine. Background technique: [0002] Labeling machine, as the name implies, is a mechanical equipment used to attach labels, and the bottle body is a labeling product that is often used by labeling machines, because the existing general bottle body is cylindrical, and the bottle attached to the bottle body The label is generally arc-shaped, and the side of the label is prone to warping, so the bottle labeling machine needs to be equipped with a corresponding device for pressing the label. Invention content: [0003] The purpose of the present invention is to address the deficiencies of the prior art, and provide a pressing device applied to a labeling machine, which can press the label of the bottle body, eliminate the edge warping of the label, and ensure the labeling quality. [0004] To achieve ...
