Anti-counterfeiting mark positioning compound transfer device for inserting coil substrate

Abstract

The invention belongs to the field of anti-counterfeiting mark processing equipment and particularly relates to an anti-counterfeiting mark positioning compound transfer device for an inserting coil substrate. The anti-counterfeiting mark positioning compound transfer device is characterized by comprising a sizing device, a mark point printing paired roll, a compound paired roll, a stripping paired roll, a finished product pull roll and a waste PET (Polyethylene Terephthalate) film pull roll which are sequentially arranged, wherein the sizing device consists of a glue tank, an anilox roll, a plate roll and an imprinting bottom roll which are sequentially arranged, wherein the lower part of the anilox roll is immerged in the glue tank; the imprinting bottom roll is driven by a servomotor; the plate roll is linked with the imprinting bottom roll by virtue of a gear transmission mechanism; the plate roll drives the anilox roll to rotate; a tracking and aligning device is arranged between the mark point printing paired roll and the compound paired roll; the tracking and aligning device is provided with two light sensors; and the light sensors and the servomotor are connected with a PLC (Programmable Logical Controller) system. By utilizing the device, positioning compound transfer, namely overprinting, can be rapidly realized, and the overprinting precision is high, the inserting coil substrate consumed in the overprinting adjustment process is greatly reduced in comparison with that of a traditional operation, and the cost is saved.

Description

technical field [0001] The invention relates to an anti-counterfeit label positioning composite transfer device for off-line substrates, belonging to the field of anti-counterfeit label processing equipment. Background technique [0002] In the process of traditional anti-counterfeiting label processing, sometimes due to the need for special anti-counterfeiting labels, there is a situation of secondary printing (that is, overprinting the printed substrate that has been offline). It must be ensured that each anti-counterfeiting label is sprayed with an anti-counterfeiting query code. Therefore, there is an off-line detection process of the anti-counterfeiting code during the processing of the anti-counterfeiting label, and the anti-counterfeiting label that fails the test (that is, the anti-counterfeiting query code is not sprayed) is marked as discarded It is screened out in the later packaging process of finished products. After the off-line inspection process is completed,...

Problems solved by technology

At present, the traditional secondary printing method is to put the detected anti-counterfeiting label directly on the secondary printing line, and transfer the anodized aluminum to a suitable position. The specific operation is as follows: the operator visually observes the position of the anodized aluminum, and manually operates the control system , Adjusting the motor speed of the embossing bottom roller usually requires repeated observations and adjustments, and the operation is cumbersome. On the one hand, a large amount of off-line substrates will be wasted during the adjustment process. On the other hand, positioning compound transfer (ie overprinting) The efficiency is low and the accuracy is difficult to guarantee
