Description

Technical Field

[0001] This utility model relates to the field of printing line technology, specifically a printing line. Background Technology

[0002] Screen printing is a widely used printing technology. During printing, a squeegee forces ink through the mesh of the printing plate onto the substrate, creating an image identical to the original artwork. Screen printing machines are simple, easy to operate, and offer convenient and inexpensive printing and plate-making processes, making them highly adaptable.

[0003] A screen printing production line disclosed in CN110126445B includes screen printing equipment. The equipment comprises a loading / unloading device, a dust removal device, a screen printing device, a drying mechanism, a collecting mechanism, a turntable, a turntable drive mechanism, a conveying device, a feeding device, and multiple positioning devices. The dust removal device removes dust from the material on the turntable. The positioning devices position the dust-removed material. The screen printing device performs screen printing on the positioned material. The drying mechanism dries the printed material on the carriers of the conveying device. The collecting mechanism collects the carriers filled with dried material. The loading / unloading device transports material from the carriers of the conveying device to the turntable or transports printed material from the turntable to the carriers of the conveying device. This automated process achieves material loading, dust removal, positioning, printing, unloading, drying, and collection, improving the efficiency and quality of screen printing.

[0004] While existing printing lines can handle material feeding, dust removal, positioning, printing, unloading, drying, and collection, their printing quality is poor. Therefore, we propose a new printing line. Utility Model Content
