A label paper adsorption structure of a labeling machine

Abstract

The invention provides a label paper adsorption structure of a labeling machine. The label paper adsorption structure comprises a suction disc fixed at the lower end of a labeling arm capable of moving up and down; a vacuum chamber is formed in the suction disc; a plurality of suction holes communicated with the vacuum chamber are formed in an adsorption surface at the lower end of the suction disc. The label paper adsorption structure further comprises an air blowing rod positioned under a label outlet in the labeling machine; an air blowing channel communicated with an external air source is formed in the air blowing rod; a plurality of air blowing holes distributed at intervals and communicated with the air blowing channel are formed in the air blowing rod; along the horizontal forward conveying direction of labels in the labeling machine, the air blowing directions of the air blowing holes are obliquely arranged towards the front upper part and face the adsorption surface at the lower end of the suction disc. When a printer in the labeling machine prints and conveys the labels forwards from the position of the label outlet, airflow blown out by the air blowing rod has first component force towards the front part and second component force towards the upper part; the first component force is used for pushing the labels to be continuously conveyed forwards, and the second component force is used for supporting the labels, therefore, the labels are ensured to be accurately adsorbed by the suction disc.

Description

technical field [0001] The invention relates to a labeling machine used in a cloth cutting production line, in particular to a label paper adsorption structure of the labeling machine. Background technique [0002] The machines on the fabric cutting production line mainly include cloth spreading machines, labeling machines and cutting beds, etc. Among them, the labeling machine prints the cutting information on the label paper through an industrial printer, and uses pneumatic components to stick the label paper after biaxial coordinate positioning. An industrial automation equipment for the garment industry to the corresponding position of the cloth. The labeling machine replaces the traditional marker paper of the same shape covered on the fabric to mark the size and remarks of the cut piece, so as to save paper and other consumables and reduce costs, and the labeling machine is linked with the cutting bed, cloth spreading machine and other equipment Control to realize the...

Problems solved by technology

[0004] However, in the actual labeling process, the above-mentioned automatic labeling machine cannot solve the following problems:

[0005] 1. There are various sizes and specifications of the label, but the relative position between the vacuum adsorption component and the printer cannot be adjusted, so that the vacuum adsorption component cannot accurately absorb the labels of each specification, resulting in unstable capture of the label and affecting the labeling effect. standard quality

[0006] 2. After the downward distance of the Z-direction movement component is preset, it can no longer adjust the downward pressure labeling stroke of the vacuum adsorption component, so it cannot automatically adapt to the different labeling distances caused by different layers of fabrics and different thicknesses of fabrics, so , when the preset down-pressing labeling stroke of the vacuum adsorption component is greater than the actual labeling distance, it is very easy to lose fabrics, especially high-elastic fabrics and leather fabrics; when the preset down-pressing labeling stroke of the vacuum adsorption component is smaller than the actual labeling distance , it is very easy for the label to fail to press on the fabric, or the label is not stable
