Double-station rotary screen printing machine

Abstract

The invention discloses a double-station rotary screen printing machine. The double-station rotary screen printing machine comprises a rack, a conduction band transmission mechanism and double-station printing units, wherein each double-station printing unit comprises a sizing agent supply mechanism, a rotary screen scraping printing mechanism and two printing rotary screens, and the two printing rotary screens in each double-station printing unit are mounted on the rack through a rotary screen mounting frame; each rotary screen mounting frame comprises two rotary screen fixed seats and rotary screen movable seats; each sizing agent supply mechanism comprises two sizing agent supply pipes which transversely penetrate through two printing rotary screens; and each rotary screen scraping printing mechanism comprises two scraper plates, two printing magnetic bars and a plurality of electromagnets. According to the double-station rotary screen printing machine, printing processing of two textile fabrics can be completed at the same time, input of manpower and material resources is effectively reduced, consumption of energy such as water, electricity and gas can be greatly reduced, and the energy-saving and emission-reducing effects are obvious; and meanwhile, according to the printing machine, proper printing rotary screens can be freely selected according to the widths of the textile fabrics, and meanwhile, the mounting positions of the printing rotary screens can be flexibly adjusted according to the patterns of the textile fabrics, so that the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of textile printing equipment, and in particular relates to a double-station rotary screen printing machine. Background technique [0002] At present, there are various types of rotary screen printing machines used for textile printing, such as scraper type, magnetic rod type, scraper magnetic rod hybrid type, scraper magnetic rod dual-purpose type, etc. When any type is a single-station printing machine, that is, every One printing unit can only install one printing rotary screen, and can only complete the printing process of one textile fabric at a time. In practical applications, in order to improve production efficiency and reduce production costs, some manufacturers try to make two patterns at both ends of a wide printing rotary screen and print and process two narrow textile fabrics at the same time.

Problems solved by technology

In practical applications, in order to improve production efficiency and reduce production costs, some manufacturers try to make two patterns at both ends of a wide printing rotary screen and print and process two narrow textile fabrics at the same time. Production efficiency, reduced production costs, but production is greatly restricted

First of all, a printing rotary screen can only supply printing paste of one color, so it is required that the colors of the two patterned fabrics printed at the same time are exactly the same, and the printing colors are exactly the same, which greatly limits the pattern of the printed fabrics. Flexibility and diversity of type registration

Secondly, the number of orders for textile fabric printing patterns and the number of color sets are different due to different needs. It is difficult to arrange production for one printing rotary screen to print two different orders at the same time, especially when customers repeat additional orders. The probability of additional orders at the same time is almost zero. Using rotary screen printing with two patterns to process a piece of textile fabric will not only not reduce the cost, but will also generate huge waste.

Third, because the textile fabric is flexible, when the two fabrics are sent to the printing guide belt, the width and edge of the two fabrics will change on the printing guide belt. It is necessary to adjust the phase parameters of the printing rotary screen and the printing rotary screen according to the change of the fabric. The horizontal and oblique positions, and it is difficult for one printed rotary screen to meet the changes of two fabrics at the same time

Therefore, in actual production practice, in addition to the production of chemical fiber imitation wax printed cloth fabrics, a wide-format printing rotary screen can be seen to produce two patterns at the same time, and print two narrow-format patterns at the same time, but textile fabrics are one For wide-width fabrics, after printing, one piece of fabric is cut to form two narrow-width fabrics. In theory, it still belongs to single-station printing. There are almost no production cases where companies use one rotary screen printing to process two textile fabrics.
