Why is the roller the core component of the roller printing machine?

For the pursuit of low-cost thermal transfer printing, the roller printing machine is nothing but the best choice. Since the roller printing machine adopts high temperature, high pressure and full oil technology, the running clock of the machine is in a high temperature and high pressure state. Therefore, the safe and stable operation of the roller printing machine is extremely important.

Different sizes of rollers have different widths for the transferred fabric. Rollers of different sizes and diameters will also have different transfer speeds. The larger the diameter of the roller, the faster the transfer speed. The length of the drum is slightly smaller than the width of the flower cloth, so that the color paste and the fabric are not wasted when the flower cloth is transferred.

Generally, the circumference of the drum is equal to the integral multiple of the upper and lower dimensions of the unit pattern. If there is any extra, it is necessary to use a lathe, and the number of the car depends on the size required for the drum when engraving. When the drum passes once, the circumference of the flower cylinder is reduced by about 1.5 to 2.5 mm, and the old flower cylinder can be used for the depth of the old pattern carving. When the circumference of the flower cylinder reaches about 350mm, it can no longer be used. The number of times the pattern is repeatedly engraved on the circumference of the cylinder is called the number of times. For each set of rollers, the circumference size requirements are the same, the error should not exceed 0.1mm, and the precise geometric patterns are required to be higher, otherwise it is easy to cause the flowers to be inaccurate.

After the flower car is good, first fix the surface breeze by hand, then put it on the grinding machine and grind it with medium coarse grindstone, then grind it with fine and hard stone, make the surface of the flower tube smooth, and the flower tube can not be touched by hand. For later use.

The quality and material of the drum have a great influence on the plate making. The material of the drum is generally copper-zinc alloy (containing 97.5%-98% copper, 2%-2.8% zinc, containing less than 0.2%), and the hardness should be 78-84HB. Generally, the circumference of the drum is 4.2-446 mm, the drum is hollow, the inner diameters of the two ends are different, and the inner diameter is tapered. The one with a large inner diameter is called a big head, and the one with a small inner diameter is a small head. The roller is mounted on the tapered shaft of the transmission part. Just coincides with the lumen of the tube. There is a key pin on the drum, and the keyway of the shaft stem must be aligned when the drum is mounted.

The drum is the core component of the roller drum heat transfer machine. The appearance of the drum passes through the lathe, grinding, etc. The iron spray of the exterior of the roller printing machine is mainly used for anti-sticking. Teflon has certain environmental requirements. If the roller is not properly maintained, it will cause the appearance of Teflon to fall off.
