Dual-purpose printing equipment with functions of transfer printing and direct printing

Abstract

The invention discloses dual-purpose printing equipment with the functions of transfer printing and direct printing. The equipment consists of a preprocessing device and a printing device, wherein the preprocessing device consists of a reticulate pattern roller (45) and a bearing roller (46); the printing device consists of a front main roller and a rear main roller, and each main roller is matched with printing plate rollers, roller barrel washing devices and roller barrel drying devices. The dual-purpose printing equipment disclosed by the invention adopts integrated dual-purpose design with the functions of the transfer printing and the direct printing and can meet requirements for low cost and high speed of the direct printing, and the dual-purpose printing equipment can also meet requirements for high fineness of the transfer printing.

Description

technical field [0001] The invention relates to printing and dyeing machinery in the textile industry, specifically a dual-purpose printing equipment for transfer printing and direct printing suitable for various fabrics such as cotton, nylon, polyester, etc. The equipment can realize high-quality single-sided and double-sided transfer printing and direct printing. Background technique [0002] There are many types of printing and dyeing techniques and machinery, and a wide range of products. At present, the main printing processes of printing on the market include screen printing, roller printing, platen printing, transfer printing and digital inkjet printing. The corresponding equipment is mainly rotary screen printing machine, flat screen printing machine and roller printing printing machine. , Table printing machine, transfer printing machine, digital inkjet printing machine, etc. In the early days, most of the printing in our country used roller printing, such as the ...

Problems solved by technology

But in practical application we find: one, the disclosed paperless transfer printing technical scheme all is to replace paper with these recyclable materials such as metal foil or plastic tape, but the surface tension of these materials is all very low, and pattern printing Solvent-based ink is required to be used on metal foil or plastic tape, and the organic solvent volatilizes a lot during the production process; secondly, if high-precision printing effect is to be obtained, the surface of metal foil or plastic tape needs to be treated by corona and other methods, and after After several times of recycling, the surface treatment effect of the plastic tape disappears, resulting in a serious decline in printing quality; again, as stated in the article "Paperless Thermal Transfer Printing Technology" in the 8th issue of "Printing and Dyeing" in 2003, "some difficulties still need to be overcome, such as tension. "Regulation problem", since neither the steel belt nor the plastic belt can be stretched and rebounded, in order to achieve the precise positioning of the pattern and the fineness of the pattern line in the transfer process, it is inevitable to need to adjust the transfer temporary carrier Tension control is carried out, and due to the reciprocating application of the steel belt and the plastic belt, the more the number of cycles, the small deformation of the steel belt or plastic caused by each tension stretch will be accumulated and enlarged, because its stretch cannot be recovered, so it exceeds a certain The number of cycles and the accumulated deformation will seriously affect the quality of the printing. Therefore, the replacement of the steel belt and the plastic belt is relatively frequent in actual production. Compared with paper, the production cost is difficult to be effectively reduced.
