Screen printing machine workbench
The structure of the screen printer is constantly changing with the changes in the market. The main change is the change in the movement form of the workbench. The change in the movement form of the workbench makes the printing change from intermittent to continuous, realizing the relative automation of the printing process.
1) Flip screen printer
The screen printer can only print on one plane of the product at a time. If the workbench can rotate 90 degrees or 180 degrees, the screen printer can print on different planes of a product. For example, square containers such as beer plastic frames and storage plastic frames are often used for this type of screen printer. Its workbench is controlled by a servo motor and can rotate freely in the vertical direction.
2) Rotary screen printer
The workbench of the rotary screen printer has multiple even-numbered stations forming a disc, which are arranged and rotated along the central axis and enter the printing device in turn. Pre-press devices such as flame treatment devices, plasma treatment devices, and electrostatic dust removal devices can be set between the stations. Post-press devices such as tunnel drying devices and UV curing devices can make the printing process more perfect.
3) Conveyor belt screen printer
A conveyor belt screen printer is a screen printer that is equipped with a conveyor belt. The conveyor belt can run continuously. The operator can place the products on the conveyor belt at a certain interval, and the products will be transported to the printing position in sequence.
4) Slide screen printer
A slide screen printer is a screen printer that can move along the guide rail, or move left and right, or move forward and backward. When moving out, the product can be removed and placed, and when moving into the printing position, printing can be performed. The slide screen printer avoids contact between the operator and the printing device, improving safety.
What is a touch screen?
A touch screen is an inductive display screen that can receive touch commands. Users can operate the device (such as parameter setting, function selection, etc.) by touching the screen with their fingers or a stylus. It is simple, intuitive and convenient. Touch screens are widely used in various intelligent pad printers, screen printers, hot stamping machines and various automated printing equipment.
Why does a turntable screen printer need a touch screen panel?
A multi-station rotary screen printer is a more complex semi-automatic screen printer. Due to the installation of a turntable, the screen printing process is continuous, which improves production efficiency. It is equipped with a touch screen panel and has the following advantages:
1. Centralized control.
The turntable screen printer involves multiple stations such as loading, dust removal, printing, drying, and unloading. It is necessary to set multiple parameters such as printing speed, pressure, turntable speed, drying temperature, etc. The touch screen can integrate these parameters in a visual interface, and users can adjust them by touching and clicking.
2. Improve the setting accuracy
The rotary screen printer can be suitable for most flat products. The parameter settings of the touch screen can be digitized and stored in the same way, which is conducive to the management of the characteristics of different products, and the setting accuracy is also greatly improved.
4. Fault prompt
The touch screen itself is also a display screen, which can display the real-time operation status of the screen printer on the screen. At the same time, when the screen printer fails, it can also be judged from the screen, and the fault can be eliminated according to the prompts on the screen. The jamming of the screen printer, motor abnormality and sensor abnormality can be quickly eliminated.
5. Adaptation to automation
Modern rotary screen printers are often equipped with automatic feeding and detection devices. The back-end can be connected to UVLED curing machines and IR tunnel furnaces and connected to automated production lines. The touch screen can be used as a central control hub to realize the linkage between equipment and external devices.
In summary, the touch screen panel is the core control component for the rotary screen printer to achieve precise, efficient and automated production, and can realize friendly operation of human-computer dialogue.
