   The semi-automatic hot stamping machine adopts manual loading and unloading, and the production efficiency is difficult to improve. The frequent contact between the hand and the hot pressing device also causes unnecessary safety hazards. Therefore, the products with large orders and relatively fixed product shapes use automatic hot stamping. The machine has become a rigid demand in the market. Greeting card industry, gift box industry and jewelry industry were the first to gain access to automatic hot stamping machines and have developed rapidly. Such a bronzing machine adopts an automatic stacker, which can automatically raise the worktable according to the requirements of bronzing conveying. The whole process basically does not require human intervention, all mechanized operations, the bronzing speed reaches 1200 pieces per hour, and the safety factor is also greatly improved. 

    The fully automatic servo flat gift box and paper box packaging hot stamping machine is a professional equipment used for hot stamping of gift boxes and paper box packaging. The following is its relevant introduction:

Structural composition

• Servo drive system: It is the core power part of the equipment. It is driven by a servo motor and can accurately control the movement of each component to achieve high-precision hot stamping positioning and stable running speed, ensuring the accuracy and consistency of the hot stamping pattern.

• Hot stamping system: It includes hot stamping plate, heating device, pressure regulating device, etc. The hot stamping plate is engraved with the pattern or text to be hot stamped. The heating device provides the required heat for the hot stamping plate, so that the electrochemical aluminum foil is transferred to the surface of the gift box or paper box at a certain temperature and pressure, forming a clear and firm hot stamping effect.

• Feeding and receiving system: The feeding system can use belt conveyor, roller conveyor, etc. to smoothly convey the gift box or paper box to the hot stamping station. After the hot stamping is completed, the receiving system collects or transports the finished products to the designated location in an orderly manner to achieve automated continuous production.

• Control system: Generally equipped with advanced PLC control system and human-machine interface, it can realize precise control and parameter setting of the hot stamping process, such as hot stamping temperature, pressure, speed, hot stamping time, etc. It also has functions such as fault diagnosis, alarm prompts, and production data statistics, which are convenient for operation and management.

Working principle

When the equipment is working, the feeding system transports the gift box or paper box to the hot stamping station, the servo drive system accurately controls the relative position of the hot stamping plate and the paper box, the heating device makes the hot stamping plate reach the set temperature, and the pressure regulating device applies appropriate pressure to make the electrochemical aluminum foil fit closely with the surface of the paper box to complete the hot stamping transfer, and then the receiving system collects or transports the hot stamped paper box away.

Features and advantages

• High-precision hot stamping: The precise control of the servo system enables the position accuracy of hot stamping patterns and texts to reach the millimeter level or even higher, with clear and smooth edges, which improves the overall beauty and grade of the product.

• Efficient production: With a high degree of automation and fast running speed, it can achieve continuous and uninterrupted production. The production efficiency is greatly improved compared with traditional hot stamping machines, and it can meet the needs of large-scale production.

• Wide range of applications: It can adapt to gift boxes and paper boxes of different sizes, shapes, and materials. It can also adjust the hot stamping temperature, pressure, time and other parameters according to different hot stamping requirements to achieve a variety of hot stamping effects.

• Stable and reliable: It uses high-quality electrical components and mechanical parts, with stable performance, low failure rate, long service life, and the equipment has good compatibility and scalability, and can be upgraded and transformed according to production needs.

Machine advantage

• Automatic hot stamping of paper, PVC, PU and other materials used in the printing and packaging industry. It includes automatic paper feeding, automatic length walking hot stamping paper, automatic paper collection, automatic rewinding of hot stamping paper and other functions.
• Automatic paper feeding and automatic paper collection are controlled by servo motors, the paper is accurate, and the error can be controlled within 0.1mm. Both the paper feed table and the paper collection table can be automatically adjusted according to the height of the paper, ensuring the precise positioning of the paper collection and paper feeding.
• The automatic bronzing spindle is controlled by a 1500W servo motor with brakes + planetary reducer, which can easily achieve a pressure adjustment range of 0-1.5 tons.
• The bronzing temperature control system uses high-precision temperature control switches, thermocouples, and 400W heating plates, and the temperature difference range can be controlled within 2-3 °C, which is extremely effective for temperature-sensitive aluminum hot stamping film.
• The automatic paper walking of aluminum galvanized aluminum and bronzing paper is controlled by stepper motor + high-precision pulley, and the fixed length of hot stamping paper is within 0.2mm.
• The whole machine is programmable logic controller + touch screen man-machine interface + high-precision servo motor + cylinder control operation, reasonable design, high precision, small appearance and space-saving, especially suitable for jewelry box packaging, wallet watch box packaging, small leather shell, red packet bag, display box PVC and other products surface gilding.
