The roller heat press machine-do you know how it is pressurized?

The installation of the multi-function roller heat press machine is divided into a lining cloth and a white cloth. The lining cloth adopts a tight type, and the white cloth is mostly loose, and is fed by super-feeding, so that the fabric is suspended in the shape of the cloth ring, and the speed of feeding the super-feeding roller is controlled by the photoelectric tube to ensure the white cloth is relaxed. The state enters the front of the car, making the fabric tension different and achieving excellent printing results. The lining-free printing machine only has a white cloth installed in the cloth.

Pressing mechanism of the garment rotary heat transfer machine: the pressing mechanism applies pressure to the flower cylinder through the bearings at both ends of the flower cylinder shaft. In order to make the printed pattern clear, the left and right prints are averaged, and the pressure must be applied properly. The pressure is too light, and the printed pattern is light in color, so that the bottom is too thick, it will be ambiguous, and it will additionally increase the power loss and increase the wear of the parts. Usually, the thick-lined, large-patterned flower cylinder and the pressure roller as a light plate are lightly pressed, and the flower tubes of fine lines, clouds, and snowflakes are heavily pressed.

The line pressure ranges from 100 to 600 N/cm and is commonly used from 200 to 400 N/cm. The total pressure of each flower tube can reach 2 × 104 - 8 × 104N depending on the length of the flower tube.

In addition, the pressurization mechanism should also meet the following process and operational requirements:

 Heat transfer machine

1. The calender heat press can not only control the advance and retreat of the flower tube and the bearing seat, but also precisely adjust the pressure on the left and right sides respectively.
2. The pressurizing system should be flexible. When the joint of the cloth passes through the pressing point or the shaft is bent, it can act as a buffer to reduce the pressure passively.

How to choose calender heat transfer diameter and thickness of the drum

The rollers of calender heat transfer in the drum line are mostly cylindrical parts and are usually divided into drive and moving rolls. Suitable for rotary screen printing machines, digital printers and other conveying equipment. So how do you choose the diameter and thickness of the drum line? Let me give you a brief explanation:

 Calender Heat Transfer

After the drum is formed, it is generally surface treated, and some are painted, galvanized, rubberized, chrome-plated. According to the size, it can be divided into large-sized mechanical drums, the length can reach more than 10 meters, the diameter can reach more than 1500MM, and the small flat rollers like the belt conveyor on the automatic assembly line, the length is generally 1 meter. Within, the diameter is between 159MM.

The roller diameter of sublimation heat press transfer machine selection range: 25mm, 2mm, 38mm, 42mm, 50mm, 57mm, 60mm, 76mm, 80mm, 89mm. The principle of determining the diameter of the drum is that when the tensile stress of the conveyor belt is large, the additional bending force should be smaller, whereas when the bending force is large, the tensile stress is smaller, and a smaller roller can be selected.

 Rotary Heat Transfer Machine

The calculation of the thickness for the roller heat press machine's drum usually depends on the diameter of the drum, the length of the cylinder, and the tension of the transport tape and the wear during braking. Therefore, the calculation of the thickness of the drum is difficult, and the calculated value is small, and the wear and the ease of manufacture are also considered, so the thickness of the cylinder is usually selected to be thick. After determining the thickness of the shell, we need to check the strength of the shell, but because the shell is subjected to normal and tangential loads, and the size of the load will vary along the circumference of the drum. Therefore, there is no accurate calculation method for the calculation of the thickness of the roller line drum. Although the finite element calculation can relatively accurately calculate the results, there is still a lack of a common procedure for the calculation of the conveyor roller, and only the finite element of the individual drum can be performed. Analysis, but can not analyze the calculation of the roller line drum.

Modern roller heat transfer machines,What are the improvements of it?

Roller heat transfer machines are widely used in flags, non-woven fabrics, clothing fabrics, towels, sheets, mouse pads and other products of sublimation transfer. From the beginning of the production of hot presses to the current development, a lot has happened. Improve. Do you know what is the difference between the hot press and the previous one?

Roller Heat Transfer Machine

Although the roller heat press machine was already produced and applied as early as 1785, the printing machine developed to the present has long been not only the original function and structure, but also the effect of the current printing machine. It is very powerful, it has a special microcomputer control, has a liquid crystal screen, can directly display relevant data through the screen, such as temperature, time, etc. during the transfer process, can be directly controlled through the LCD screen , with higher precision and better results.
At the same time, in the printing machine, every main wall board used or the deflection axis is also carefully crafted, and these parts are repeatedly polished and audited to ensure the quality of the whole roller printing machine. The printing machine, in the actual use process, of course, can bring better results for everyone, and can make people achieve a very satisfactory experience, so that everyone is happy to use such a printing machine.

Why A Good Roll Drum Heat Press Machine Cannot Transfer High Quality Images

When using a roll drum heat transfer machine, we sometimes find that even if you buy a good quality machine, the printing effect is not very good, you know why? This is not only about the machine, but also about many factors.

1.Transfer temperature

The temperature depends on the optimum temperature for sublimation of the dye, the heat resistance of the fiber and the heat transfer time.

Roll Drum Heat Press Machine

Usually on the heat transfer machine instructs the transfer temperature between 190 ~ 230 ℃, it is difficult to correctly judge the temperature of real transfer.
Strictly speaking, the transfer machine transfer temperature is not equal to the actual transfer temperature, it is related to the heating roller processing accuracy, heat carrier oil cycle, loading method.
The sublimation temperature of heat transfer printing should be lower than the melting point of the fiber polymer, and the strength of the fabric will not be damaged. Polyester processing temperature is 180 ~ 210 ℃. Within this temperature range, the molecular weight of dye sublimation is between 230 and 270
The molecular weights in the range of disperse dyes are generally classified into three categories:
Fast dye disperse dye: temperature about 180 ℃ can sublimate the hair color, temperature, and then improve the color changes, edge penetration will happen.
Good disperse dye: in 180 ~ 210 ℃ temperature range can be sublimated hair color. The hair color has a flat curve. The effect of temperature on dyeing is not that it is more suitable for transfer printing of disperse dyes.
Dye disperse dye: late in 180 ~ 210 ℃ can't very well under the condition of dye
sublimation, dye their hair. Good hair color can be obtained by raising the temperature. This dye is highly temperature-dependent when dyed.
Generally suitable for thermal transfer printing dye conditions:
(1) must be under 210 ℃ sublimation ink dye, fixed on the fiber, can obtain good washing fastness and iron fastness.
(2) heat transfer printing dyes can be fully sublimated into gas-phase dye macromolecules after heating, which can condense on the surface of the fabric and diffuse into the fiber.
(3) thermal transfer printing on the transfer paper affinity is small, the fabric affinity is large.
(4) the dye should have a bright, bright color.

2.Transfer the pressure

Heat Press Machine

Flat embossing machine: 10kPa is the standard transfer pressure. If the pressure is insufficient, the transfer paper and the printed cloth are not compact enough, and the printing pattern is not uniform and the color is not clear. On the other hand, if there is too much pressure, the feel and style of the printed fabric will also change.
Roller heat press machine: in order to make the transfer paper and the printed fabric overlap closely, the blanket must be tightly coated on the surface of the hot roller, the appropriate pressure is generally controlled at 12kPa.
Vacuum negative pressure heat transfer printing machine: under the condition of negative pressure (13.3kPa) can obtain good color and penetration effect, and printing fabrics feel good.

3.Transfer time

In the actual processing, the transmission time is 15~45s. Transfer time is affected by transfer temperature, fiber type, and the type of woven and knitted fabric.
Bad hot stamping pattern:
(1). Color sublimation: temperature is too low or pressure is not uniform or time is too short.
(2).Blurred pattern: too long will spread the ink.
(3).Pattern dull: pressure too high or temperature too high.
(4).Pattern scar: hot stamping time is too long.
(5).Pattern tone: uneven pressure or uneven object transfer coating.
(6).Adhesive paper: too high or too long temperature can not make the material transfer coating deterioration.
(7).Patterns fade easily: transfer temperature is too low or too short.
The above is for reference only, please adjust it according to the actual situation. Using ordinary color ink - jet transfer paper transfer temperature can be very high, sublimation transfer paper transfer rate is low.

4.Color fastness

The color fastness of the transferred fabric depends mainly on the following three factors: the fabric to be processed; Transfer paper used and dyes printed on transfer paper; Transfer process conditions.
Heat transfer printing has the characteristics of fast drying, washable, strong color fastness and rich color, which can be used in clothing, household textiles (curtains, sofas, tablecloths, umbrellas, shower curtains, suitcases and bags) and other products.

Heat Press Machine

Therefore, when we using calender heat transfer, temperature, pressure, and transfer time are all key factors in determining the quality of a good image.
