Background

The transfer printing refers to a mode that a printing stock is an irregular special-shaped surface, a steel gravure is used, a semispherical transfer printing rubber head is cast by silicon rubber, the concave rubber head is used as an intermediate, patterns on a copper or steel plate are pressed to a printing surface by the rubber head, and ink is transferred to the printing stock to complete transfer printing. The ink storage modes are divided into an oil basin type pad printing machine and an oil cup type pad printing machine. The ink cup type pad printing machine is used for sealing and storing ink, is relatively environment-friendly, and can ensure better stability of the ink in the printing process.

According to the traditional ink cup type pad printing equipment, an oil cup system (comprising an ink supply device and a doctor blade) is generally adsorbed and pressed on a steel gravure by adopting a strong magnet, the doctor blade is of a circular or elliptical ring structure, and the steel gravure is scraped once and pad printing is performed once. The main defects and disadvantages are: 1. the strong magnet with the traditional structure is positioned in an oil cup system in an exposed mode and is surrounded by printing ink. For ink with high viscosity, after a period of pad printing, the ink tends to accumulate on the edge and periphery of the strong magnet, and the quality of pad printing is affected when the ink reaches a certain thickness. Therefore, the inside of the oil cup system, particularly the position of the strong magnet, needs to be cleaned after the oil cup system is used for a period of time. Due to the limitation of the embedding mode and shape of the strong magnet, the embedding gap between the strong magnet and the oil cup is difficult to clean, and the hidden trouble that the ink accumulation influences the transfer printing quality cannot be eradicated. 2. Even if the ink cup system is cleaned, the oil cup system must be moved away from the steel intaglio plate, the oil cup system has strong magnetic adsorption, so that the moving operation is very inconvenient, and once the oil cup system is moved away, ink stored in the oil cup system is easy to leak, thereby polluting the environment and wasting the ink. 3. When the ink cup system is cleaned and installed again, due to the fact that the magnetic force of the strong magnet is strong, when the ink cup system is installed on a computer, care must be taken, the ink cup system is prone to being rapidly adsorbed on a working face uncontrollably due to poor control over the magnetic force, and the ink scraping knife is damaged. Thus, the prior art is in need of improvement and advancement.

The upper part of the scraper seat is provided with an ink adding hole and an ink exhaust hole which are communicated with the ink storage tank at the lower part. The doctor blade is made of tungsten-cobalt hard alloy or composite zirconia hard ceramic and is triangular in cross section.

Compared with the prior art, the technical scheme of the utility model has the main advantages that: 1. adopt the detachable assembly structure of magnetic disc and scraper seat, keep apart strong magnet and printing ink completely, avoided the printing ink to gather the adhesion in original strong magnet fit-up gap department completely, can guarantee the quality of bat printing for a long time. 2. When the oil cup system needs to be disassembled or cleaned, the distance between the magnetic disc and the scraper seat can be changed through the adjusting bolt, the magnetic attraction force to the working surface below is weakened, and then the magnetic disc is separated from the scraper seat, so that the magnetic attraction force of the strong magnet is far away from the working surface and the steel intaglio below, and the oil cup system is easily assembled or disassembled. 3. Correspondingly, under the condition that the magnetic attraction force is not interfered, the scraper seat can be easily placed on the steel intaglio, and the magnetic disc is assembled after the scraper seat is placed, so that the ink scraper on the working surface of the scraper seat is effectively protected. 4. In the transfer printing process, when the size of magnetic attraction needs to be adjusted, the gap distance between the end face of the magnetic disc and the bottom of the groove of the scraper seat is changed only through the adjusting bolt, so that the transfer printing machine is very convenient and fast.
