Description
Technical Field
The invention relates to the technical field of thermal transfer printing, in particular to an electromagnetic superconducting thermal transfer printing machine.
Background
The electromagnetic heating silica gel roller of the traditional heat transfer printer is mainly divided into two types, one type is an all-metal roller with chrome plating or Teflon plating on the surface, and the other type is an external heating silica gel roller.
The object of the all-metal roller transfer printing can only be a flexible material, and the transfer printing can not be carried out on rigid materials (such as an acrylic plate, an aluminum plate, a stainless steel iron plate and the like). The external heating silica gel roller can transfer rigid materials, and the structure of the external heating silica gel roller is shown in fig. 1, but the external heating silica gel roller also has great defects in use:
1. the area of the external heating silica gel roller which can be contacted and heated with an external heating device is limited, generally the area is at most 1/3 of the external circumferential surface of the silica gel roller, so that the requirement on the power of the heating device is extremely high, the minimum requirement is more than 15KW, and the heating cost is high;
2. when the silica gel roller is preheated, the silica gel roller needs to rotate ceaselessly to heat the whole roller, so that an independent transmission device needs to be added to the silica gel roller, the use cost of the silica gel roller is further increased, the size of the silica gel roller is increased, and the installation difficulty is increased;
3. when the thermal transfer printing is carried out, the surface temperature of the silica gel roller generally needs to be heated to 160-200 ℃, and because the contact area between the silica gel roller and the heating device is limited, if the surface temperature of the silica gel roller is heated to 180 ℃, the silica gel roller needs to be heated for at least more than 2 hours, so that the preheating time of each startup use is long, and the working efficiency is reduced;
4. because the silica gel roller needs to be divided into a part to be contacted with the heating device, the contact area of the heat transfer film and the silica gel roller is greatly compressed, and only 1/4 of the outer circumferential surface of the silica gel roller is remained at most, so that the heating area of the heat transfer film is small, the heat is greatly wasted, and the transfer efficiency is further reduced.
Of course, other fields also include internally heated silicone rollers, but these cannot be used normally in the field of thermal transfer printing. The minimum finished product encapsulation thickness of an internal heating silica gel roller on the market at present can only reach 7mm, the thermal conductivity of silica gel is poor, the higher the temperature required during heating is, the larger the temperature difference between the inside and the outside is, generally speaking, if the outside needs to reach 120 ℃, the temperature of the inside needs to reach 200 ℃, and if the outside needs to reach 180 ℃, the temperature of the inside needs to reach 280 ℃. The structure of the silica gel roller is generally encapsulated outside the metal roller, the temperature resistance of an adhesive contacting the silica gel and the metal is poor, the temperature resistance of the adhesive is generally not more than 220 ℃, even if the adhesive with the highest temperature resistance on the market is used, the temperature of the adhesive is generally not more than 260 ℃, otherwise, the adhesive is failed, and the silica gel falls off from the metal roller, so that the internally heated silica gel roller cannot be used in the thermal transfer industry at present.
