Double-compression roller structure for label delivering machine

Abstract

The invention relates to a double-compression roller structure for a label delivering machine. The structure comprises a drive roller (1) arranged on a mainboard (2) of the label delivering machine and two groups of compression rollers (3), wherein the two groups of compression rollers (3) have the same structures and are arranged on the two sides of the drive roller (1); a label body paper (21) and a label (22) are pressed on the surface of the drive roller (1) by one of the compression rollers (3); and after the label (22) is separated from the label body paper (21), the label body paper (21) moves around the drive roller (1) of the label delivering device again and is pressed on the surface of the drive roller (1) by the other compression roller (3). By adoption of the invention, during the movement of the label, the label body paper can be equally stressed so that the label body paper cannot be torn even in the state of high-speed movement. The double-compression roller structure for the label delivering machine is reasonable in design, convenient and practical.

Description

technical field [0001] The invention relates to a double-pressure roller structure for a label feeder, which belongs to the transformation technology of the double-press roller structure used in the label feeder. Background technique [0002] The double pressure roller is the core part of the label feeder. Its purpose is to press the label on the driving roller to ensure that there is no slippage between the label and the driving roller when the driving roller drives the label, so as to improve the label delivery and stop of the label feeder. standard accuracy. The structural schematic diagram of the existing double pressure roller is as follows figure 1 As shown: the label backing paper 21 bypasses the active roller 1 of the label feeder, and is pressed on the surface of the active roller 1 by two pressing rollers 3; before the label 22 is separated from the label backing paper 21, it is not pressed by the pressing roller 3, and The double pressure roller structure adopte...

Problems solved by technology

The structural schematic diagram of the existing double pressure roller is as follows figure 1 As shown: the label backing paper 21 bypasses the active roller 1 of the label feeder, and is pressed on the surface of the active roller 1 by two pressing rollers 3; before the label 22 is separated from the label backing paper 21, it is not pressed by the pressing roller 3, and The double pressure roller structure adopted by the labeler has two disadvantages. One is that when the label 22 is threaded, the label channel is not open, so it is troublesome to thread the label 22; the other is that the label backing paper 21 is easily broken at high speed.
