Why is the Roller the Core Part of the Sublimation Roller Printing Machine?

Hi! Nice to see you again, my dear friends! Today's topic is about the rotary heat transfer machine. For the pursuit of low-cost heat transfer printing, sublimation roller printing machine is nothing more than the best choice, because the drum printing machine uses high temperature, high pressure, full oil technology, the machine running clock is a high temperature and high pressure, therefore, the drum It is extremely important that the printing machine can run safely and stably.

Different specifications of the drum, the transfer of the fabric is different in width, different size and diameter of the drum, the transfer speed will be different, the greater the diameter of the drum, the faster the transfer rate. The length of the drum is slightly less than the width of the fabric so that no color paste or damage to the fabric is lost when the fabric 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 excess, the lathe must be used. The number of carts depends on the required size of the drum for engraving. Once each drum passes, the circumference of the cylinder decreases by approximately 1.5-. 2.5mm, the old flower cylinder can use the old pattern carved depth car to continue to use, when the barrel circumference reaches 350mm, it can not be used again.

The number of times the general pattern is repeated on the circumference of the cylinder is called the number of times. The drum size of each pattern must have the same circle size, the error should not exceed 0.1mm, and the precise geometry pattern requires higher, otherwise it may cause inaccurate flowers.
After the truck is well-washed, first use the hand to repair the surface of the sand hole, and then placed on the grinding barrel machine with medium rough grinding stone mill, and then use fine-grained, hard hard stone water mill, so that the barrel surface smooth, polished barrel, can not touch For later use.

The quality and material of the roller have a great influence on the plate making. The material of the drum is generally a copper-zinc alloy (containing 97.5% to 98% of copper, 2% to 2.8% of zinc, less than 0.2% of impurities), and the hardness should be 78 to 84 HB. Generally, the circumference of the drum is 4.2-446mm, the drum is hollow, and the inner diameters of the two ends are different. A cone is formed, a large inner diameter is called a big head, a small inner diameter is a small head, and the drum is mounted on the tapered shaft stem of the transmission part.

Consistently with the flower cylinder cavity, there is a key pin on the drum, which must be aligned with the keyway of the stem. The drum is the most important part of the drum printing machine. The appearance of the drum passes through the lathe, grinding, etc. The outer part of the drum printing machine is mainly coated with Teflon to prevent sticky threads. Teflon has a certain use environment, if the drum maintenance is not appropriate, it will cause the appearance of Teflon off.


If you have the intention to buy a roller printing machine or change, customize the roller, it is better to call the Fei Yue Digital INC. (www.feiyuepaper.com). We will provide you with the perfect solution.

These Problems that Should Be Paid Attention to When Using the Sublimation Roller Printing Machine

图片
Rotary heat transfer machine is often used to print fabric continuously (roll to roll heat press) and to print large fabric parts such as signs and banners which may be too large for a standard platen press. Drum machines can also be used to print sports apparel and other cut apparel parts. Drum machines are more productive than platen machines for sublimation printing on cut apparel parts and are therefore used when production volume is high. Drum machines are not used however to print onto rigid substrates such as wood, metal or ceramic tile. First, the printing process of the roller printing machine When the roller printing machine is printed, the flower cylinder is pressed against the pressure roller. There are several flower tubes around the pressure roller, and several flower tubes are called several sets of printing machines. When printing, the paste roller under the flower tube is used to transfer the color paste to the flower cylinder. In order to scrape

Roller Transfer Printing Machine is an indispensable equipment tool in the hot textile industry. The printing machine on the market is full of styles and brands. There are countless product specifications for a roller printing machine. Let our technician for you analyze the difference between the roller printing machine and the rotary screen printing machine. First, can it be used continuously? The roller transfer printing machine is a process for printing on a fabric with a copper cylinder engraved with a concave pattern, which is also called a copper roller printing. The engraved roller is referred to as the flower tube. When printing, firstly make the surface of the flower tube stained with color, and then use a sharp and flat scraper to scrape off the surface color paste of the unembossed part of the flower tube, leaving a color paste in the concave pattern. When the flower cylinder is embossed on the fabric, the color paste is transferred to the fabric to be print
