Shuttle type automatic two colors screen printing machine

Application- Printed Samples show

       Liquor bottles, beer bottles, and many beverage bottles are made of glass. They are not as easy to make positioning points as plastic bottles. Therefore, using a fully automatic screen printer for multi-color printing will involve the problem of overprinting. At present, the linear shuttle fully automatic screen printer and the turntable fully automatic servo screen printer are relatively mature screen printing solutions for glass bottles. The shuttle-type fully automatic screen printer is composed of multiple sets of screen printing devices and UVLED curing groups combined with a shuttle-type workbench. The glass bottle is grabbed by the robot via the conveyor belt and placed on the fixture of the workbench. After flame treatment, the first color printing starts, and then UVLED curing is performed. The bottle and the fixture continue to move forward. The servo rotation mechanism will rotate the bottle in the opposite direction to the starting printing position of the first color, and the second color printing will be performed. The second color UVLED curing. Until all colors are overprinted. Since only one set of fixtures is used in the printing process of all colors of the bottle, the relatively unchanged printing position is maintained, and multi-color overprinting is achieved. The overprint accuracy of the shuttle-type fully automatic screen printer is not very high, but it can reach 0.05mm, which basically meets the requirements of multi-color UV screen printing for most glass bottles. Compared with the flat multi-color turntable screen printer, it has a high cost performance.

    For the multi-color overprinting of cylindrical substrates, a more economical method is to use a set of clamping fixtures to fix the products and enter the printing stations one by one. Since the position changes of the products are completed on the same set of fixtures, the product is avoided. The position error during the transfer process, so the overprint angle is increased. This type of screen printing machine is widely used in multi-color overprinting of wine bottles and other products without positioning points. Because the machine adopts the design idea of reciprocating transmission of fixtures, the printing efficiency of the machine is not high, and it is especially suitable for multi-color printing of wine bottles with small batches. The machine also have one set  photoelectric tracking and positioning, so the structure is relatively simple, and it is a substitute for the turntable servo screen printing machine.  The SZD-1043 is specially designed for screen printing on beer bottles, drinking bottle and glass. It uses a very simple technique to settle registration problem. The key technique is to print with melted high temperature glass ink, then bum in a high temperature oven so that the ink merges with the glass. The project  features very small investment and fast return.

Glass and ceramic bottles Automatic linear shuttle silk screen printing machines and automated turntable silk screen printing machines

    Glass bottles are the most environmentally friendly materials for wine and beverage packaging. Silk screen printing is one of the most important ways of decoration. As the most important purchasing direction, automated silk screen printing machines, linear shuttle silk screen printing machines and automated turntable silk screen printing machines have always been favored by the market. How to choose linear shuttle and flat turntable glass bottle silk screen printing machines can refer to the following description:

• Structure and operation mode

   The linear shuttle silk screen printing machine adopts a linear assembly line structure, which consists of a feeding conveyor belt, a servo shuttle workbench, a silk screen printing station, a UV curing device or an IR curing device, and a feeding conveyor belt. The glass bottles are fed in sequence by the conveyor belt, and the servo shuttle workbench (X/Y axis movement) grabs the bottles and moves them horizontally to the silk screen printing station; the first color of the bottle is printed, and the shuttle table transfers the bottle to the curing area, and then transports the glass bottle to the second color printing, and the second color is cured until all colors of silk screen printing are completed. The flat turntable screen printer is centered on a horizontal turntable, with multiple stations distributed at equal angles. It is equipped with loading, CCD positioning, dust removal, positioning, screen printing, UV curing, unloading and other devices. The glass bottle is installed on the turntable fixture through a manipulator, and the turntable rotates intermittently at a fixed angle (such as 60°/station); the bottle passes through each station in turn with the turntable, realizing the "loading → processing → printing → curing → unloading" cycle, and multiple stations work synchronously.

• Applicable scenarios

   The automatic linear shuttle screen printer is suitable for small batch and multi-variety production (such as customized advertising bottles, sample trial production), with flexible changeover; large diameter glass bottles (such as wine bottles, beverage bottles), better linear conveying stability; simple pattern printing (such as brand logo, barcode), low cost. The automatic rotary screen printer is suitable for large-scale standardized production (such as cosmetic bottles and medicine bottles), and has outstanding high-speed multi-color printing efficiency; For scenes with high printing precision requirements (such as gradient patterns and fine text), the rotary indexing positioning is more accurate; For scenes that require the integration of multiple processes (such as the simultaneous completion of dust removal, flame treatment, and UV curing), the rotary station layout is more compact.

• Design Differences

The automatic linear shuttle screen printer uses a servo motor to drive the ball screw to achieve linear reciprocating motion. The automatic rotary screen printer uses a cam divider or a servo indexing motor, which has high positioning accuracy and is suitable for high-speed rotation.
