Shoe heel automatic pad printing machine

Shoe heel pad printer

1. Servo Shuttle Rotary Worktable

• Working Principle:

• The servo motor drives the worktable to realize the shuttle motion, which can accurately control the horizontal displacement of the worktable between different workstations. For example, in the process of heel pad printing, it can accurately move the heel from the loading position to the first ink cup ink printing position, and then shuttle to the second oil cup position for two-color printing. The rotation function is to drive the rotating mechanism through the motor, so that the heel can rotate at a certain angle, which is convenient for printing from multiple directions and meets the printing needs of patterns at different angles on the heel.

• Advantages:

• High-precision servo control ensures the accuracy of heel positioning, and the accuracy of shuttle and rotation movements can reach a millimeter or even smaller error range. This high precision helps to improve the position accuracy of the printed pattern and ensure the registration accuracy between the two-color patterns and between the pattern and the heel edge. Moreover, the movement speed of the worktable can be flexibly adjusted according to actual production needs to improve production efficiency.

2. Special clamp for heels

• Design features:

• Specially designed for different shapes of high-heeled shoes and leather shoes (such as thin heels, thick heels, special-shaped heels, etc.). The clamp adopts suitable materials and structures to ensure that the heel can be firmly clamped to prevent the heel from moving during printing, and to avoid damage to the heel surface. For example, for stiletto heels, the clamp may use a clamp with soft pads to gently clamp the heel from both sides; for thick heels, it can be designed as an embracing clamp to increase the contact area with the heel.

• Advantages:

• Special clamps can adapt to various heel shapes and sizes to ensure the stability of the heel during pad printing. Stable heel position is one of the key factors to ensure printing quality, which can effectively reduce printing defects such as blurred patterns and deformation caused by heel shaking or displacement.

3. PLC touch screen control system

• Function realization:

• PLC, as the core control unit, coordinates the actions of various components of the pad printer through pre-written programs. The touch screen is a human-machine interactive interface. The operator can intuitively set various parameters on the touch screen, such as the speed and displacement of the servo shuttle rotary table, the ink volume and scraping speed of the two-color oil cup horizontal scraping system, and the time of delayed printing of the rubber head. At the same time, the touch screen can also display the operating status and fault information of the equipment.

• Advantages:

• Simple and convenient operation, no need for operators to remember complex instruction codes. Through the intuitive graphical interface and simple touch operation, the working mode and parameters of the pad printer can be quickly adjusted. Moreover, the PLC control system has a high degree of reliability and stability, can run stably for a long time, and reduce downtime caused by control system failure.

4. Two-color oil cup horizontal scraping system

• Working principle:

• The two-color oil cup contains two different colors of ink respectively. The horizontal scraping system moves the scraper horizontally on the surface of the oil cup to evenly distribute the ink on the surface of the oil cup, so that the pad printing rubber head can dip into the appropriate and uniform amount of ink. In two-color printing, the two ink cups can be controlled independently to ensure that the ink supply of the two colors does not interfere with each other.

• Advantages:

• This system can accurately control the amount of ink to ensure that the ink of the two colors is evenly distributed during two-color printing. Even ink supply helps to print colorful and full patterns. At the same time, the independent two-color ink cup design facilitates the switching and adjustment of colors, and improves the flexibility of two-color printing.

5. Pad delay embossing system

• Working principle:

• After the pad printing pad is dipped in ink, a certain delay time is set through the control system so that the pad is pressed down at the appropriate time point to print the ink on the heel. This delay time can be adjusted according to the material, shape, drying speed of the ink and other factors of the heel. For example, for some heels with uneven surfaces, appropriately extending the delay time can allow the pad to better fit the heel surface and ensure complete transfer of ink.

• Advantages:

• The pad delay embossing system can improve the effect of ink transfer and make the printed pattern clearer and more complete. By adjusting the delay time, it can adapt to different heel characteristics and printing requirements, effectively reducing printing defects such as incomplete ink transfer and incomplete patterns.

6. Advantages of patented pad printing machines in heel printing

• Comprehensive advantages:

• These components work together to give patented pad printing machines significant advantages in printing high heels and leather shoes. It can accurately print two-color patterns on heels, whether it is complex brand logos, exquisite decorative patterns or functional patterns. It can be completed with high quality. The entire pad printing process is efficient and stable, and due to the protection of its patented technology, it may have unique advantages in certain performance aspects, such as higher printing accuracy, faster production speed or more convenient operation experience, which can meet the high quality and high efficiency needs of footwear manufacturers for heel printing.
