Pad printing effects

The workbench of the pad printing machine initially adopts a pneumatically controlled elliptical turntable. This kind of workbench is noisy and has low overprint accuracy, which has certain limitations for products with high requirements. Most pad printing machines now tend to install a circular turntable controlled by a divider. The circular turntable is set at a certain angle, and after turning through an equiangular arc length, different printing stations are formed.

The easiest way for the circular turntable is to install it on the monochrome pad printing machine to realize the continuous delivery of products. Due to the increase in the number of stations, this kind of turntable pad printing machine can be equipped with a pre-press flame treatment device, or it can be added Loading manipulator and unloading manipulator are installed, and they are linked with the UV processor or IR tunnel furnace in the subsequent process to realize the automation of product pad printing.

Outstanding advantages of the rotary pad printer:

1. Multi-station continuous printing

The rotary table is equipped with multiple independent stations, ranging from 4 to 12 stations, which can complete the processes of loading → printing → drying → unloading at the same time. The production efficiency is doubled compared with the single-station pad printer, and the labor intensity of workers is reduced by 30%.

2. High positioning accuracy

The rotary table is mostly driven by servo motor + precision indexing plate, with high positioning accuracy. The uniformity of the printing position during the rotary table conveying process is guaranteed.

3. Better safety

The distance between the operator's product placement station and the printing station is far, which can effectively avoid the damage of the printing action to the human body and reduce direct contact with the ink.

4. Full process automation

The rotary pad printer has a higher degree of automation, which can complete the closed loop of the whole process of loading → positioning → printing → drying → unloading, reduce manual intervention, and significantly improve production efficiency. Since the rotary pad printing machine has multiple stations, different process units can be added according to the specific characteristics of the product, such as pre-press processing, pad cleaning device, robot and ink curing device, which greatly enhances the adaptability of the product.

What is PLC?

PLC is the abbreviation of Programmable Logic Controller. It is a digital operation system designed for industrial machinery. It controls various types of machinery or production processes through programmable memory, storing instructions for performing logical operations, control, timing, counting and arithmetic operations. In simple terms, PLC is like the "brain" of industrial equipment, which can automatically control the operation of equipment according to preset programs. PLC is widely used in various automatic and semi-automatic printing machinery, including pad printers, screen printers, hot stamping machines and thermal transfer machines. Its application in turntable pad printers and turntable screen printers is more mature.

Benefits of PLC control of turntable pad printer

The turntable pad printer is a pad printer with a multi-station rotating turntable. Compared with the pad printer with a shuttle table, the turntable pad printer ensures the continuous delivery of products, reduces the invalid operation time, and significantly increases the efficiency of the pad printer. Since the turntable pad printer has more complex movements, the use of PLC control can increase the stability of the pad printer. The PLC-controlled pad printer has the following main features:

• High precision: PLC has a fast response speed and can accurately control the positioning of the turntable, the operation of the electrostatic dust removal device, the number of cleaning times of the rubber head cleaning device, the lifting time of the pad head, etc., and the position of the unloading robot.

• Good stability: Strong anti-interference ability, can adapt to the dust, vibration, voltage fluctuation and other environments in the industrial site, and reduce downtime.

• Easy to maintain: The program has a high degree of visualization. When a fault occurs, the problem can be quickly located through the PLC's built-in diagnostic function, which is convenient for maintenance; at the same time, the modular design facilitates component replacement.

• High degree of automation: It can be linked with the feeding system, sensors, cylinders, motors, tunnel furnaces or UV curing machines and other equipment to realize automatic feeding, printing, unloading and other processes, reduce manual operations, and improve production efficiency.
