Turntable Full Automatic screen printing machine for bottle caps

The role of bottle caps in wine packaging is very important. It has the functions of sealing, anti-counterfeiting, decoration, etc. With the fierce competition in the wine industry, the decoration on wine bottle caps has also reached a demanding level. Many high-end brands have won the favor of consumers by using advanced printing technology on the bottle body and bottle caps. Wine bottle caps are divided into plastic bottle caps, glass bottle caps, metal bottle caps and other materials. The fully automatic wine bottle cap screen printing equipment has unique advantages in the brightness of ink, the accuracy of overprinting, and personalized expression.

Structure

Feeding mechanism: Usually a vibration plate is used for automatic material distribution or a crawler feeding structure, which can automatically feed the wine bottle caps into the printing position in turn. Some are also equipped with optical fiber detection devices to realize the function of no material prompt and no printing.

Transmission mechanism: Usually a flat turntable is used, and the turntable is controlled by a high-precision divider, which can accurately transmit the bottle caps to each station.

Printing system: Generally, the printing heads are arranged in sequence in the circumferential direction of the turntable. The printing and rotation movements of the printing heads are controlled by servo motors. The turntable drives the wine bottle caps to pass through the screens of different colors for printing in sequence to realize the three-color printing function.

Positioning system: Mostly adopt pneumatic latch type or visual positioning system, such as dual camera visual positioning, to ensure the accurate position of the wine bottle caps during the printing process, and the positioning accuracy can reach 0.01mm or even higher, to ensure the registration accuracy of the printed pattern.

UV Drying unit: Generally, a UV/LED drying system is equipped at the station behind each printing head. After printing, the ink is quickly dried and cured, so that the ink is firmly attached to the surface of the wine bottle cap to prevent the pattern from blurring or falling off.

Control system: It consists of a PLC programmable controller and a touch screen, which can realize the functions of parameter setting, operation control and fault diagnosis of the equipment. It is easy to operate and maintain.

Features

High efficiency: The turntable design can realize continuous cycle printing, fast printing speed, and can print thousands of wine bottle caps per hour, greatly improving production efficiency.

High precision: The positioning system is accurate, which can ensure the color registration accuracy of three-color printing, and the printed pattern is clear and accurate, meeting the high quality requirements of the surface decoration of wine bottle caps.

Strong adaptability: It can be applied to wine bottle caps of various materials and shapes, such as plastic, glass, metal and other materials, as well as wine bottle caps of different shapes such as round and square.

Easy operation: It is operated through the touch screen, and the parameter setting is intuitive and simple. The operator can master the operation method of the equipment after simple training.

Fully automatic multi-color bottle caps screen printers//Characteristics
An automatic loading system, including a sorting tray and elevator, can be configured based on the bottle cap sample. The automatic loading system automatically positions the bottle caps onto the conveyor track, identifies the front and back faces, and feeds them into the printer's feed rail. Based on the sensor signal, the feed robot automatically clamps the bottle caps onto the turntable's fixture shaft, which provides a tight fit between the fixture shaft and the printed bottle cap. The high-precision 16-station rotary table rotates sequentially, performing electrostatic dust removal (CCD top feature detection and side feature detection can be added to meet customer needs). Workpiece presence detection, first-color screen printing, LED UV ink curing, second-color screen printing, LED UV ink curing, third-color screen printing, LED UV ink curing, fourth-color screen printing, LED UV The ink cures, and the side of the bottle cap is screen-printed and then hot-stamped. A robotic arm automatically unloads the material, and a conveyor automatically delivers it. The container is manually collected and inspected. The four printing colors can be freely combined, and unused stations can be disabled. Hot stamping is performed over the silk-screen font. Screen printing is automatic when the material is ready; if there are no parts, the screen printing stops. Hot stamping also works the same way: if there are parts, hot stamping stops. Automatic color overprinting is completed. The above steps are repeated to achieve continuous, automatic printing without stopping, achieving high efficiency and high-quality production.
