Description

Technical Field

[0001] The invention relates to a double-layer sticker printing system and a double-layer sticker manufacturing method, and in particular to a double-layer sticker printing system and a double-layer sticker manufacturing method capable of adjusting a printing path. Background Art

[0002] Nowadays, the competition among commodities is getting more and more fierce. Products can interact with consumers. There are many promotional activities that have gained considerable advantages. Stickers are used to provide commodities with a good promotion platform. However, known promotional stickers can be divided into single-sided scratch-off stickers or double-sided scratch-off stickers. Single-sided scratch-off stickers are stickers with product advertisements, instructions and scratch-off areas printed on the front of the sticker. When the products are displayed on the shelves, unscrupulous customers will take the opportunity to steal and scratch the scratch-off area on the product, and then put the product back after obtaining the serial number, causing losses to the merchants. Secondly, the traditional process of scratch-off stickers is front printing, back printing, award or serial number printing, protective film application, scratch-off area formation, partial gluing and cutting into shape. It requires at least 4 to 6 processes in total, and the procedures are cumbersome, labor-intensive and time-consuming, which makes the cost relatively high.

[0003] Secondly, currently, hospitals use identification tags to identify patients. When patients go to the hospital for various examinations, the hospital will attach the patient's personal identification tag to the patient's identification bracelet to ensure that each patient can receive exclusive medical treatment, medicine, examination or surgery without making mistakes. However, hospital staff need to serve many patients at a time, so the hospital needs to be very careful when attaching patient identification tags. If the wrong information is found or the identification tag is attached to the test container or test manual of different patients, the test results will not correspond to the real patient, resulting in inevitable medical negligence. Summary of the invention

[0004] The main purpose of the present invention is to provide a double-layer printed sticker manufacturing system and a double-layer sticker manufacturing method. The system of the present invention can operate consistently and print the upper and lower layers of paper at the same time, simplifying the manufacturing process and thus reducing the manufacturing cost.

[0046] In summary, the double-layer sticker printing system and the double-layer sticker manufacturing method of the present invention have the following advantages. First, after the upper and lower layers of paper are printed, they are folded by the two paper folding machines, and the gluing machine is used to flatten and calibrate the paper, and then the knife die is used to cut the paper, and finally the paper is rolled. Different from the known method, the paper is first folded into a roll, which is easy to cause paper continuous errors, and the paper is first cut into single sheets and cannot be calibrated. Secondly, the length of general relief printing equipment is about 17 meters, and the longer the paper path is, the easier it is to deviate; however, the total length of the adjustable path printing port of the present invention is only 3 meters, which can avoid the problem of paper deviation caused by excessive path length. Furthermore, the adjustable path printing port of the present invention has at least eighteen kinds of flexible printing path adjustments, the main purpose of which is to use multiple first printing machines 21 and multiple first ultraviolet curing machines 22 without causing waste of resources.
