Structure of printing blade

The present invention relates to a structure for a printing blade, in particular to an elastic blade body which is combined with a bottom edge of a rigid locking substrate, so that the elastic blade body is reciprocally filled on the metal intaglio or the relief plate and scrapes off the ink without scratching the metal intaglio Or letterpress, which can extend the service life of the scraper unit and the metal gravure or letterpress, so that the uniformity of the fine lines at different positions can be better, and the scraper can be positioned quickly, accurately and in a foolproof manner, requiring no time-consuming and labor-intensive adjustment procedures. Scraper design that improves print quality and saves costs.

According to the printing technology, it is a well-known technology. If it is applied in the electronics industry, it can greatly reduce production costs and increase production efficiency. At present, the electronics industry is moving towards the demand for high-precision lines. When the line is less than 50um, the commercial printing technology has not met the demand. Therefore, relevant industries in various countries have invested in the research and development of precision metal gravure and letterpress transfer processes, hoping to replace the current high. Pollution, high cost yellow light development process.

However, the transfer of metal gravure (6) or letterpress for printing is usually made of metal or rubber (a few) and printed with a metal scraper (4), as shown in Figure 12 and Figure 13. As shown in the fourteenth figure, this method has short life, scratches, and defects in printing defects on the metal intaglio (6) or the relief and the metal blade (4). In order to overcome the problem of short life, the industry generally uses metal materials to make metal intaglio (6) or letterpress, and after laser, etching or electroforming, the wire is formed on the metal gravure (6) or the relief, and then the metal Gravure (6) or letterpress is sent for various hardening treatments, and the cost is not high, but only in this way, regardless of industry The metal gravure (6) or the relief is sent to various expensive hardening treatments, but the metal doctor blade (4) is used to reciprocally scrape the metal intaglio (6) or the ink on the relief, due to the metal intaglio (6) or the relief The higher hardness causes the metal blade (4) to be worn at the bottom edge of the blade (41) when it is reciprocated 1-2 times. In addition to the frequent replacement of the metal blade (4), it is also worn by the worn metal blade (4). When reciprocating on a metal intaglio (6) or a relief, it is also easy to scratch the surface of the metal intaglio (6) or the relief, which causes the trouble of printing defects, and makes the metal intaglio (6) or letterpress which is hardened by expensive hardening. Unable to use due to damage.

In addition, the conventional metal scraper (4) is directly mounted on the clamping portion (51) of the blade holder (5) with a screw (53) by a plywood strip (52). The known metal scraper (4) has no alignment design, and the metal scraper (4) bottom edge blade (41) must have a high-precision fit with the metal intaglio (6) or relief surface, resulting in the initial installation of the metal scraper (4). And the horizontal correction requires more time adjustment, which is also likely to cause the capacity drop during the replacement of the metal scraper (4).

Therefore, this creation uses a new design of the blade design to effectively solve the above problems, and meets the requirements of rapid installation, high stability and low consumables cost.

In view of the practical difficulties of the scraper used in the above-mentioned printing equipment and the lack of improvement, the presenter hopes to provide a breakthrough design to enhance the practical effect, which is devoted to research and design, and comprehensively collects many years. Engaged in the professional technical knowledge and practical experience of related product design and production and the results of research and design, and finally developed a structure of a printing scraper to provide users.

The blade unit of the present invention comprises a rigid locking substrate and an elastic blade body coupled to the bottom edge of the rigid locking substrate. On the rigid locking substrate, more than one positioning hole and locking hole are provided, and the blade holder is disposed on the blade holder. The corresponding locking pin and the screw hole are arranged on the locking surface, and the locking hole on the rigid locking substrate of the blade unit and the positioning pin of the blade holder can be set after the locking, and then the rigid locking is performed by the screw The locking hole on the solid substrate locks into the screw hole on the blade holder, so that the blade can be positioned quickly, accurately and in a foolproof manner. It requires a time-consuming and labor-intensive adjustment procedure to improve printing quality and cost, and the blade unit is The rigid locking substrate and the elastic scraper body can reduce the force of the scraper unit being pressed by the scraper seat, and the elastic scraper body is combined with the elastic scraper body at the bottom edge of the rigid locking substrate to make the elastic scraper body on the metal intaglio or the relief plate. Reciprocating filling and scraping ink does not scratch the metal gravure or letterpress, which can extend the service life of the doctor unit and the metal intaglio or letterpress, and make the fine line uniformity at different positions of the printing better.

The main purpose of this creation is to use a specially constructed scraper unit with a dedicated scraper holder to improve the traditional problem. This creation has the following advantages:

1. The scraper adopts a metal or hard structure combined with the design of the elastic scraper body to prevent the scraper from damaging the precision metal gravure or letterpress and prolong the service life of the scraper and the metal gravure or relief.

2. The scraper has one or more positioning holes, which can be quickly combined with the corresponding positioning pin on the blade holder to achieve horizontal correction, reducing the time for replacing the blade and the total cost of printing.

3. The scraper unit can be replaced at one time, or only the elastic scraper body can be polished and trimmed to achieve the purpose of cost-saving for repeated use, and the metal can be recycled and reused to reduce environmental pollution.

4. Compared with the metal scraper, the scraper with metal combined with the elastic scraper body can improve the effect of attaching the metal gravure or the relief, and it can be confirmed that the uniform effect can be achieved on the printing thin line, and there is no problem of line recess on the thick line.

5. The elastic scraper body can be combined with metal or hard structure by means of sticking, pouring, clamping and squeezing, and the elastic scraper body can also be changed in shape and hardness according to requirements.

6. The elastic scraper body can be added with conductive materials and combined with a low-resistance hard material to eliminate static electricity generated during the printing process.

7. The scraper can also be used with a heated blade holder to achieve a heating effect, which can reduce the viscosity of the printing paste and achieve a good printing effect.
