Description

Technical Field

[0001] The utility model relates to the field of dyeing and finishing equipment, in particular to a multifunctional combined printing machine. Background Art

[0002] A printing machine is a device that prints the required patterns and designs on fabrics with one or more dyes or pigments of different colors. At present, the printing process of fabrics decorated with gold and silver powder on the market generally uses a rotary screen printing unit for printing first, and then another rotary screen printing unit uses a dye containing small sequins for overprinting. However, the rotary screen has the defects of long multi-color plate making cycle, high cost and insufficient color richness. In order to meet market demand and improve production efficiency, it is urgent to develop more reasonable combined printing equipment. Utility Model Content

[0003] The utility model aims to provide a multifunctional combined printing machine.

[0004] The technical solution to achieve the purpose of the utility model is: a multifunctional combined printing machine, which includes a guide belt transmission device installed on a frame, and a first rotary screen printing unit, a digital direct injection printing unit and a second rotary screen printing unit that can be used for gold and silver powder printing are installed on the guide belt transmission device in sequence from front to back along the running direction of the fabric.

[0005] Furthermore, the first rotary screen printing unit and the digital direct printing unit are equipped with a first pre-drying unit.

[0006] Furthermore, a second pre-drying unit is installed between the second rotary screen printing unit and the digital direct inkjet printing unit.

[0007] Furthermore, a scraper coating unit is installed at the front end of the first rotary screen printing unit.

[0008] Furthermore, a plurality of the first rotary screen printing units are installed on the guide belt transmission device along the running direction of the fabric.

[0009] Furthermore, a plurality of the digital direct-injection printing units are installed on the belt-guide transmission device along the running direction of the fabric.

[0010] Furthermore, a plurality of the second rotary screen printing units are installed on the belt guide transmission device along the running direction of the fabric.

[0011] The multifunctional combined printing machine realized by the utility model can carry out gold and silver powder sizing printing, direct inkjet printing and rotary screen overprinting in one machine at the same time, and can also carry out gold and silver powder printing, direct inkjet printing or rotary screen printing alone, and after automatic direct inkjet printing, rotary screen printing overprinting can be used, which can easily align the overprinting of the flowers, so as to achieve continuous, multi-combination and multi-functional effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the structure of the multifunctional combined printing machine according to an embodiment of the utility model, wherein the arrow represents the running direction of the fabric. DETAILED DESCRIPTION

[0013] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0014] like Figure 1 As shown, a multifunctional combined printing machine includes a belt guide transmission device 1 installed on a frame 10, on which a scraper coating unit 2, two first rotary screen printing units 3, a first pre-drying unit 4, four digital direct injection printing units 5, a second pre-drying unit 6 and four second rotary screen printing units 7 are installed in sequence from front to back along the running direction of the fabric.

[0015] The scraper coating unit of the multifunctional combined printing machine realized in this embodiment can apply coating and inkjet pre-treatment additives; each of the first rotary screen printing units can respectively perform offset printing of gold and silver powder, white ink, etc.; after offset printing of gold and silver powder, white ink, etc., the fabric is pre-baked by the first pre-baking unit, and after pre-baking, the fabric is subjected to fine direct-jet printing by the direct-jet inkjet printing unit; after direct-jet printing, the fabric is pre-baked by the second pre-baking unit, and after pre-baking, the second rotary screen printing unit in the rear section performs overprinting of the previous coating, gold and silver powder, offset printing, direct-jet, etc. units.

[0016] In this embodiment, the four units of scraper coating, gold and silver powder printing, direct injection printing and overprinting are shared on one guide belt, which is convenient for synchronous adjustment of the pattern and ensuring the printing accuracy; it can also be set to separate scraper coating, separate direct injection printing and separate rotary screen printing.

[0017] The first pre-drying unit and the second pre-drying unit of the utility model are arranged as needed so as to be used in a printing process requiring pre-drying; the pre-drying unit is infrared radiation heating and may also be equipped with air blowing, which is a common equipment in the printing process and will not be described in detail here; the scraper coating unit can be used for coating or applying the pre-treatment additives required for the digital inkjet process; the number of the first rotary screen printing unit, the digital direct injection printing unit and the second rotary screen printing unit can be increased or decreased according to the process and cost control needs.

[0018] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
