Description

Screen printing machine structure improvement

Technical field

This invention relates to a printing press, and more particularly to a structural improvement of a screen printing machine.

Background technique

The screen printing machine mainly uses the scraper to reciprocate to apply the ink (colorant) to a predetermined position of the predetermined workpiece. Since the ink (color material) has viscosity, it will remain on the screen after working for a period of time. Dry ink (colorant), which in turn leads to poor print quality.

Although the ink (color material) on the screen can be removed by means of washing and unloading, the washing and unloading is not only time-consuming and labor-intensive, but also significantly reduces the production efficiency.

Both Taiwan Patent No. 542103 and Patent No. 519042 disclose techniques for scraping ink using another doctor blade. However, if the ink is dried, the use of a doctor blade to scrape the ink may result in an unclean condition and may easily damage the surface of the screen.

Summary of the invention

It is an object of the present invention to provide a structural improvement of a screen printing machine.

In order to achieve the above objects and effects, the present invention is achieved in that the screen printing machine is improved in that a sliding cylinder is provided with a pneumatic cylinder and a plurality of guiding rods, and a scraper seat is installed at one end of each guiding rod, and a connecting plate It is connected to the other end of each of the slide bars, and an actuating lever of the pneumatic cylinder is connected to the connecting plate. Further, a mounting seat extends on one side of the sliding seat, and the mounting seat can move along with the sliding seat; a nozzle device is connected to the mounting seat, and the head device has at least one nozzle. And the nozzle device is used to eject a solvent or a gas.

Thus, the solvent can be used to dissolve the residual ink on the screen, and then moved with the original scraper on the surface of the screen, the residual ink can be easily removed.

Further, the nozzle device comprises a post, two adjusting rods and two nozzles, wherein the connecting rod passes through the mounting seat; and the adjusting rod is mounted on the connecting rod and is located on two sides of the mounting seat; Second, the nozzle They are mounted on the adjustment lever separately.

Further, the adjusting rod has a plurality of adjusting holes, and the connecting rod passes through the different adjusting holes to adjust the position of the nozzle.

Further, the mounting seat extends on one side of the sliding seat, and the mounting seat is integrated with the sliding seat.

Further, further comprising a linear driving device, the mounting seat is separated from the sliding seat, the linear driving device is installed between the sliding seat and the mounting seat, and the linear driving device links the sliding seat and the mounting seat, And the linear driving device is used to drive the mounting seat to generate displacement.

The invention has the effect of quickly removing residual ink on the surface of the screen and reducing the surface temperature of the screen.

detailed description

Referring to FIG. 1 and FIG. 2, a screen printing machine includes a sliding seat (10) and a pneumatic cylinder (12) and a plurality of guiding rods (14). a scraper seat (16) is mounted at one end of each of the guide rods (14), and a web (18) (see Fig. 1) is coupled to the other end of each of the guide rods (14), and the pneumatic cylinder (12) Actuator (20) Connect the connecting plate (18). Furthermore, the doctor seat (16) corresponds to a countertop (22). A further drive mechanism (24) is coupled to the slide base (10).

Thus, the actuation of the pneumatic cylinder (12) can cause the blade holder (16) to move up and down, thereby causing the blade holder (16) to approach or away from the work surface (22). The drive mechanism (24) may be a combination of a screw set and a motor that actuates to drive the combination of the slide base (10) and the blade holder (16) to produce movement.

Referring to Figures 2 and 3, the present invention includes a mount (30) and a showerhead assembly (40). The mounting seat (30) extends on one side of the sliding seat (10), and the mounting seat (30) can be integrated with the sliding seat (10); a nozzle device (40) is connected to the mounting seat (30) ). Further, the nozzle device (40) comprises a post (42), two adjusting rods (44) and two nozzles (46). Wherein the post (42) is passed through the mounting seat (30); the adjusting rod (44) is mounted on the post (42) and is located on two sides of the mounting seat (30); (46) are respectively mounted on the adjustment lever (44).

Next, please refer to FIG. 3 again. The adjustment rod (44) has a plurality of adjustment holes (48). The use of the post (42) through the different adjustment holes (48) can be used to achieve the purpose and effect of adjusting the position of the spray head (46).

Referring to FIG. 4, the use of the present invention is to adjust the nozzle (46) to a predetermined height, and the sliding mechanism (10) is driven by the driving mechanism (24), and the nozzle (46) can be used for the working platform. The screen (26) on (22) ejects the solvent, so that the ink on the screen (26) can be dissolved, and then the scraping action of the scraper (not shown) is moved when the scraper holder (16) is moved. The residual ink on the screen (26) can then be removed.

Secondly, the solvent sprayed by the nozzle (46) can not only dissolve the ink, but also reduce the surface temperature of the screen (26), thus reducing the chance of the screen (26) being damaged by temperature.

Referring to FIG. 5, another embodiment of the present invention is that the mount (30) is separated from the slide base (10). A linear drive (50) is mounted between the sliding seat (10) and the mounting seat (30), and the linear driving device (50) links the sliding seat (10) with the mounting seat (30). The linear drive unit (50) described above may be composed of a motor (52), a screw (54) and a nut block (56). When the linear drive (50) is actuated, the combination of the mount (30) and the showerhead (40) can be displaced in the direction of the screw (54). Therefore, according to the structure shown in FIG. 5, the nozzle device (40) can perform displacement movement in two directions (X, Y directions) corresponding to the working platform (22), thereby improving the spraying of the solvent by each of the nozzles (46). Effective area.
