Automatic printing production line
In the special printing industry, pad printing machine , screen printing machine , and hot foil stamping machine have advantages that other printing processes do not have. They complement each other and play a unique role in the field of industrial printing. Some products involve not only a single printing process, but some require two, three or even more printing processes, which are combined into an integrated printing production line to complete the decorative printing of a product. These production lines embody the characteristics of a single printing process to the greatest extent, and combine the advantages of different printing processes, so that the added value of the product is greatly increased, and the production efficiency is greatly improved:
Classification by degree of automation
• Fully automatic integrated production line: With servo motor drive and PLC control system as the core, all processes from material loading, positioning, screen printing, pad printing, hot stamping to unloading are completed automatically, such as fully automatic six-color servo screen printing and hot stamping integrated printing machine, automatic seven-color servo screen printing and hot stamping integrated printing machine, etc., which can greatly improve production efficiency and product quality stability.
• Semi-automatic combined production line: Some key processes such as screen printing and hot stamping use automated equipment, but loading and unloading or other auxiliary processes require manual operation. It is suitable for small and medium-sized production or enterprises with high flexibility requirements, which can reduce equipment costs.
Classification by printing object
• Flat printing production line: used for printing flat materials such as paper, cards, flat plastic sheets, such as the common fully automatic flat screen printing and hot stamping production line, which can print exquisite patterns and texts on flat materials and perform hot stamping decoration.
• Curved surface printing production line: for round, arc-shaped and other curved objects, such as plastic bottles, glass bottles, hoses, etc., such as the fully automatic plastic bottle screen printing and hot stamping production line, equipped with a curved screen printing screen with adjustable curvature, a pad printing head that can adapt to the curved surface and a special hot stamping plate.
Classification by functional module
• Multi-color printing combination production line: emphasizes the multi-color printing function of screen printing and pad printing, and can realize multi-color pattern printing through multiple screen printing or pad printing stations, and then combine the hot stamping process to increase the decorative effect, such as the automatic eight-color servo screen printing and hot stamping integrated printing machine.
• Multifunctional integrated production line: In addition to silk screen printing, pad printing and hot stamping, it also integrates other functional modules, such as drying, UV curing, die cutting, detection, etc. For example, the silk screen printing and pad printing hot stamping production line with UV curing function can quickly cure ink and hot stamping materials after printing, thereby improving production efficiency and product quality.

1. Automatic screen printing machine and automatic hot foil stamping production line
Mainly used for printing and decoration of paper packaging. The following is a detailed introduction to its structure and use:
Structure
• Feeding mechanism: including adjustable paper stacking racks that can adapt to different specifications and quantities of paper. There are also vacuum suction cup or mechanical arm feeding devices that can accurately deliver paper to the printing station one by one.
• Screen printing mechanism: It consists of a screen printing system, a printing platform, etc. After the paper is delivered to the printing platform, it is quickly positioned, and the screen printing system quickly contacts the paper, performs the screen printing action, and transfers the printed pattern to the paper surface.
• Drying mechanism: Common ones include hot air drying ovens, infrared drying devices, etc. The printed paper can be quickly dried by circulating hot air or infrared radiation, so that the ink can be quickly solidified to prevent the ink from smudging or falling off during subsequent processing.
• Hot stamping mechanism: including hot stamping plate, hot stamping paper unwinding and rewinding device, hot pressing device, etc. After the hot stamping plate is heated, the hot pressing device controls the hot stamping plate to contact with the paper and hot stamping paper, and transfers the metal foil and other materials on the hot stamping paper to the paper.
• Die-cutting mechanism: It consists of a die-cutting knife plate, a pressing and cutting platform, and a transmission device. The paper can be die-cut according to the preset shape and size, so that the paper packaging forms a specific shape and structure.
• Receiving mechanism: There are a rewinding device and a cutting device. The rewinding device is used to neatly rewind the continuous paper products, and the cutting device can cut the paper according to the set length or quantity. It may also be equipped with an automatic stacking device to stack the cut paper neatly.
• Control system: With PLC as the core, the parameters of each mechanism can be set and adjusted through the operation interface, and the equipment operation status can be monitored in real time, with fault diagnosis and alarm functions.
2. Fully automatic glass bottle screen printing and hot foil stamping production line
Mainly used for screen printing and hot stamping on the surface of glass bottles, its structure and use are as follows:
Structure
• Feeding mechanism: generally composed of a conveyor belt, a bottle divider and a positioning device. The conveyor belt continuously transports the glass bottles to the production line, the bottle divider makes the spacing between the bottles uniform, and the positioning device accurately positions the glass bottles to ensure their accurate position in the subsequent process.
• Screen printing mechanism: including screen printing device and fixture
• Drying mechanism: Infrared drying or UV drying is often used. Infrared drying uses infrared radiation to quickly dry the ink, while UV drying is for UV varnish or UV ink.
• Hot stamping mechanism: It consists of a hot stamping plate, hot stamping paper unwinding and winding device, and a hot pressing device. The customized hot stamping plate matches the shape and pattern of the glass bottle, and the hot pressing device accurately controls the pressure, temperature and time to achieve high-quality hot stamping.
• Unloading mechanism: It is usually composed of a conveyor belt and a robotic arm, which transports the glass bottles that have completed the hot stamping to the designated location, and may also be equipped with an automatic stacking or packaging device for subsequent processing.
• Control system: With PLC as the core, the feeding speed, screen printing parameters, drying temperature, hot stamping parameters, etc. can be set and monitored through the operation interface. It has fault alarm and automatic shutdown functions to ensure safe and stable operation of the equipment.
