Abstract

The invention discloses a sponge printing process, which comprises the following six steps of: rolling up sponge; feeding into a cloth hopper; regulating sponge tension; printing in a printing house; drying in an oven; and automatically cutting. By adopting programmable and controllable programs, multi-unit synchronous variable frequency speed control and the like, the pressure before and behind a sponge roll and pressure of all contact positions of a printing roller and wide sponge are kept consistent, and in the actual printing process, the sponge is difficultly broken due to drawing, and is not creased, and print patterns are vivid and not deformed. By adopting four-pass oven drying and accurately controlling drying tunnel temperature, ink can be quickly adsorbed onto the sponge, and phenomena of ink fading, ink scattering, overlapping and the like are avoided, so that the thin and porous elastic sponge can be printed.

Description

A kind of sponge printing technology

Technical field

The present invention relates to a kind of sponge printing technology, particularly a kind of ultra-thin high elasticity sponge printing technology.

Background technology

The dyeing stamp mainly contains more than 10 kind of printing technologies such as water slurry stamp, bonding agent printing both at home and abroad, and the base material that is adopted is main with cotton, terylene, silk fiber crops, leather, nylon cloth, various PVC, denim etc. basically.But to sponge, particularly wide cut (1000mm), ultra-thin (0.6～0.8mm), carry out stamp on the sponge substrate of high resiliency (expansion and contraction >=300%), how to overcome technical problems such as decalcomania distortion and decorative pattern fracture and in available data, do not see.

Summary of the invention

Technical problem to be solved by this invention: a kind of sponge printing technology is provided, is used for the flowing water printing of ultra-thin high elasticity sponge, make the sponge decalcomania true to nature and indeformable, do not rupture.

In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:

A kind of sponge printing technology of the present invention in turn includes the following steps:

(1), rolls up in the sponge clot;

(2), get into the cloth bucket;

Automatically beat rolling, speed of a motor vehicle front and back overfeeding before and after said adjustment sponge tension force adopts, decide line time, can compile control program and multiple-unit synchronous frequency conversion arrangements for speed regulation.

Automatic deviation correction cloth clamp location, adjustment sponge tension force: the elasticity ratio of sponge confirms as 1: 1.10～and 1.15;

The stamp room is provided with water curtain ventilating system stamp; Start the water curtain ventilating system: will pour airtight relatively stamp room at the printing ink that relative dust-free workshop mixes up; The one side of adjustment stamp roller bearing immerses ink tank; The temperature of setting the stamp room is 30-35 ℃; Humidity is 45-50%; Use the water curtain ventilating system, guarantee that constant temperature and humidity is dustless in the stamp room; Use high accuracy stamp roller bearing (diameter deviation is less than 0.1mm) to carry out stamp;

Natural wind is air-dry again, natural wind is air-dry again behind the heating, drying again for elder generation's heating, drying;

Heating, drying generally is an oven for drying;

Automatically cutting: the clot rolling of cooling back is cut automatically naturally.

As a kind of improvement of the present invention; Automatically beat rolling, speed of a motor vehicle front and back overfeeding before and after the method for adjustment sponge tension force can adopt, decide line time, can compile control program and the speed governing of multiple-unit synchronous frequency conversion etc.; The tension force of sponge keeps constant during with assurance clot, last volume and stamp, guarantees that simultaneously the stamp roller bearing is consistent with the pressure of all contact positions of wide cut sponge.

As another kind of improvement the of the present invention, said oven for drying is through heating, drying, natural wind oven dry, heating, drying, four drying courses of natural wind oven dry; Said drying tunnel is four roads, adopts circulated air up and down, and one or three roads are heated oven; Two or four roads are the natural wind baking oven; Drying tunnel temperature is controlled at 55～60 ℃, and the not dried meeting of the too low printing ink of temperature causes pattern overlapping after the rolling, and temperature is too high can destroy sponge elasticity or on fire easily.

Beneficial effect of the present invention: automatically beat overfeeding before and after rolling, the speed of a motor vehicle before and after the present invention adopts, decide line time, can compile control program and the speed governing of multiple-unit synchronous frequency conversion etc. and can guarantee that sponge is rolled up front and back and the stamp roller bearing is consistent with the pressure of all contact positions of wide cut sponge, sponge is difficult for breaking in actual stamp process, wrinkle resistant pleat and decalcomania be true to nature and indeformable.Adopt four roads oven dry and accurate control drying tunnel temperature, printing ink comparatively fast is adsorbed onto on the sponge, avoided China ink occurring moving back, the phenomenon such as black, overlapping of loosing, thereby can be approaching carry out stamp on the elastic sponge of porous.

The specific embodiment

The sponge printing technology, comprise roll up 1 in the sponge clot, get into cloth bucket 2, adjustment sponge tension force 3, stamp room stamp 4, oven for drying 5 and cut 6 automatically, such six steps.

In the stamp process, beat overfeeding before and after rolling, the speed of a motor vehicle before and after adopting automatically, decide line time, can compile control program and the speed governing of multiple-unit synchronous frequency conversion etc. and guarantee that sponge is rolled up front and back and the stamp roller bearing is consistent with the pressure of all contact positions of wide cut sponge.

The temperature of setting the stamp room is that 30-35 ℃, humidity are 45-50%, and uses the water curtain ventilating system, guarantees that constant temperature and humidity is dustless in the stamp room.Use high accuracy stamp roller bearing (diameter deviation is less than 0.1mm) to carry out stamp simultaneously and guarantee that decalcomania is true to nature.

Oven for drying is through heating, drying, natural wind oven dry, heating, drying, four drying courses of natural wind oven dry; Drying tunnel temperature is controlled at 55～60 ℃; The not dried meeting of the too low printing ink of temperature causes pattern overlapping after the rolling, and temperature is too high can destroy sponge elasticity or on fire easily.
