Technical field

The utility model relates to the technical field of surface special printing equipment, in particular to a rotary automatic steaming machine.

Background technique

As we all know, cold stamping printing technology is an important breakthrough in the existing printing technology. It combines traditional printing technology and bonding technology, which not only increases the variability of printing design, but also can be produced with cold stamping and smashing. The perfect effect of the product, widely used in the production of packaging boxes, exquisite poster calendars, anti-counterfeit labels, various securities, etc., because it can not only reduce production costs, improve production efficiency, but also re-create the added value of products, Therefore, it has gradually become a new development trend in printing technology.

However, the traditional cold stamping printing technology is limited by factors such as the unreasonable structure and function design of the cold stamping printing equipment used, which leads to the following problems:

1. During hot stamping, since the curing lamp cannot illuminate the area where the substrate adheres to the electrochemical aluminum foil, the glue in this area cannot be fully cured, so that the electrochemical aluminum foil cannot be completely transferred to the substrate, resulting in hot stamping. The pattern is incomplete and the effect is poor.

2. After the printing equipment is working for a long time, the heat generated by the curing lamp and the cold-hot rubber roller in the equipment will gradually increase, and the heat-conducting component will be abnormally heated, and the high-temperature environment generated by the device will affect the printing effect of the substrate. In severe cases, it will also affect the normal operation of the device itself.

3. Under normal circumstances, a product often has multiple printed patterns, and the traditional printing equipment cannot meet the requirements of the number of printed patterns due to insufficient number of pieces of electrochemical aluminum foil.

4. The substrate or the formed printed matter is easily affected by external wind or external force during the conveyance, resulting in micro-motion or positional deviation, which may result in incomplete printing of some patterns or failure to receive the material normally.

5. The equipment unit structure is too complicated, the flexibility is poor, the space is large, the convenience of use and maintenance is poor, it can't be adjusted according to the specific environment or production needs in the workshop, and it can't form the production line with other equipment in the cold ironing technology. Moreover, the substrate can not be printed at one time, which increases the printing process and the manufacturing cost of the substrate, and reduces the production efficiency.
