What is the main reason for the failure of each part of rotary printing machine?

Today to detail the main reasons for the failure of various parts of the rotary printing machine.

The open ground (bottom). The pattern on the printed fabric is partially exposed to the ground color. Causes: low wool efficiency, thick size, too fast speed, low pressure, too shallow overshading. If the shaft core is bent, it will cause color difference between left, middle and right.

Knife blade. Forming a single or multiple colored line on the surface of the fabric. The main reason is that the scraper has a small gap (the blade has not been polished for a long time, the surface of the cylinder is rough, etc.) or some impurities (fluff, undissolved substance in the color paste, etc.), which leads to the color paste on the cylinder not being scraped clean.

Jump cut. The horizontal band left on the fabric by the shimmer of the cylinder which is not scraped by the flashing of the blade. The main reason may be that the blade is installed too low, causing the blade to flash or the hammer pressure is insufficient, of course, the sleeve is installed improperly and the gear bite is tightened can also cause the jump knife.

Dragging. Drag a small part of the same or different color of the non-pattern under the pattern. The reason may be that 1. The blade is installed too high 2. The fabric cannot be absorbed in an instant due to the thick color paste, and 3 sleeves are not arranged reasonably in the pattern. Generally can use to adjust knife Angle, color paste thickness and add knife to solve.

Splash. A splash of color from the blade landed on the fabric. If the scraper is installed too low, the speed is too fast, the slurry is too thin, and the cylinder is horizontal, this defect is easy to occur. If the problem cannot be solved through adjustment, a piece of cloth can be put on the top of the cylinder to keep out. In addition, if there is a sand hole on the cylinder, the resulting color points are made in a regular circle, different from spatter.

How to use the heat transfer printing machine skillfully?

In today’s printing industry, the technology is more and more new, and people’s ability to innovate is also increasing. The appearance of more printing machines perfectly meets the hot demand of the market at present, and the heat transfer printing machine is the printing equipment which is born with the trend.

Rotary printing machine process has a brilliant solution.

First,turn on the switch, press the general power button, the power indicator is on, turn on the heating switch, the green light of the temperature controller is on, and the machine starts to heat up.

Second, temperature setting.

1. Check the setting of the dial code before starting up the machine to prevent the blanket from burning due to artificially high setting

2. The temperature controller dial decoder digital dial in below 250 ° C, little green light to start automatic temperature control.

3. When the temperature reached around 250 ° C, red light says working temperature is to transfer.

4. Turn on the motor switch, turn it forward, and turn the speed control knob slowly from left to right to the appropriate speed.

5. If the temperature is too low when printing, set the temperature to be raised appropriately, otherwise lower.

Third, power off processing: in order to ensure the finished printing, please turn the motor belt pulley after power off, and it can still be transferred at this time with the same effect (note that the speed should be consistent).

Fourth, in order to ensure the service life of the transfer printing blankets, every time after the transfer, please dispatch dial the decoder to below 95 ° C, the machines continue to roll, until the temperature fell to below 100 ° C, you can stop.

What is the requirement of rotary printing machine for transfer fabric?

In the market more heat sublimation transfer printing equipment, small output, most of the heat transfer stamping machine to solve, for the small batch, small heat transfer stamping more flexible. However, for large volume printing, rotary printing machine is the best choice.

The rotary heat transfer machine also has certain requirements for the transfer of the fabric, the rotary printing machine is the best effect on the pure polyester fabric, because the cotton fiber is not dispersed dye color on the polyester blended fabric, the color to be lighter than the pure polyester fabric, large flower shape and “snowflake” (white) phenomenon. Pure polyamide fabric can also transfer printing, but less color, wet treatment fastness. The transfer printing process consumes twice the length of the fabric, the waste paper and the residual dye after printing are difficult to recover, and the printing color is difficult, so it is mainly used for partial printing of some fabrics, such as deformed silk fabric and knitwear, as well as some decorative printing.

Of course, roller printing machine is not omnipotent, nor is the transfer effect perfect. For cotton, real silk, linen and other fabrics pattern printing, roller printing machine is not competent. This had to be done by printing patterns on the fabric using a direct spray printing machine.

How to avoid the problem of short blanket life of rotary printing machine?

The blanket quality of rotary printing machine affects the quality and effect of transfer printing. Blanket, as an important component of calender heat press machine, is not a perfect body. Usually our blanket service life is about 2 years. However, due to the improper operation of workers often caused the blanket deformation, dirty, burnt or burned.

So how to avoid the blanket’s short life? Here are my Suggestions:

(1) Before shipment, we will conduct constant temperature finalization for the blanket to extend its service life.

(2) Special training will be given on matters needing attention for blanket maintenance and machine operation during machine installation.

(3) In addition, we have developed new functions of automatic preheating and automatic shutdown for this problem and machine safety operation. For details, please consult our business staff.

(4) It is suggested that the customer factory should be equipped with a master who can operate the machine specially, and should be responsible for the maintenance and care of the machine at ordinary times, and timely contact our after-sales staff if any problem is found.

Feiyue roller printing machine with dupont materials blanket, the use of special materials resistant to high temperature of 250 ℃, alkali resistance, acid resistance, resistance to chemical corrosion. Blanket surface flat, uniform density, good wear resistance. Stable operation, no deviation, long service life. Because the supremacy blanket has such advantages, so the supreme roller printing machine by the majority of business.

What are the printing methods of rotary printing machine?

With the continuous update of the printing industry, the technology is also continuously enhanced, and more printing machine equipment can better meet the market demand. The appearance of rotary printing machine reflects this point very well. The printing pattern is exquisite, and there is no restriction on the printing fabric, and the covering area is small. What are the printing methods of rotary printing machine? This is not very well known to the layman, today I would like to share with you the rotary printing machine how many kinds of printing methods?

There are mainly the following:

1. Swimming movement of rotary printing machine

The dye in the transfer paper ink layer is selected according to the nature of the fibre. The fabric is first soaked and rolled by the mixture of solid color auxiliaries and pastes, and then transferred by thermal pressure in the wet state, so that the dye is transferred from the printing paper of the rotary printing machine to the fabric and fixed, and finally through steaming, washing and other wet processing. When dye transfer, there should be greater pressure between the fabric and transfer paper.

2. Melting method of roller printing machine

Transfer paper ink layer with dyes and wax as the basic components. Through fusion pressure, the ink layer embedded into the fabric, so that part of the ink to the fiber, and then according to the nature of the dye posttreatment. When using the melting method, greater pressure is required, and the transfer rate of the dye increases with the increase of pressure.

3. Sublimation of rotary heat press machine

This is the most commonly used method, using the sublimation characteristics of disperse dyes, using disperse dyes with molecular weight of 250~400, particle diameter of 0.2~2 micron, as well as water-soluble carriers (such as sodium alginate) or alcohol soluble carriers (such as ethyl cellulose), oil soluble resins to make inks. In 200 ~ 230 ° C roller printing machine processing 20 to 30 seconds, make the disperse dye transfer onto polyester and other synthetic fibers and fixation.

4. Ink layer stripping method of roller printing machine

Use the ink that can produce stronger adhesion to the fiber after the heat, can make the entire ink layer spin printing paper to transfer to the fabric under less pressure, and then according to the properties of the dye do the corresponding fixation.

What is the importance and correct maintenance method of rotary heat transfer machine?

Women need cosmetics to beautify their appearance and maintain youthful beauty, and rotary heat transfer machine also needs proper maintenance. The difference is that the machine is maintained for its life, to create more benefits, to make it more effective for us to generate benefits and improve efficiency.
