Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a scraper structure for printing. Background Art

[0002] In screen printing, a scraper is needed to scrape the ink in the screen frame to transfer the ink to the workpiece to be printed. Currently, most scrapers are integrated plate-shaped parts, which are generally made of wood or aluminum alloy.

[0003] The prior art can refer to the Chinese patent with the authorization publication number CN217293893U, which discloses an open and close scraper structure for screen printing, wherein the scraper includes a blade body; the blade body includes two monomers that can be combined to form the blade body; the monomer includes a main body, a grip formed on two opposite sides of the main body, and a counterweight body arranged on the main body. However, the scraper structure still has certain defects when used:

[0004] First, the scraper body cannot move at a fixed angle during the scraping process. If the angle of the scraper body cannot remain stable, the substrate will be unevenly stressed and easily damaged.

[0005] Secondly, in the process of scraping off the ink, the ink remaining on the substrate cannot be dried, which can easily cause the pattern to be damaged when taking the printed substrate.

[0006] Therefore, a printing scraper structure is now provided. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a scraper structure for printing, which realizes the coordinated use of a moving component, a scraper component, an angle adjustment component and a drying component, thereby realizing the stable scraping of ink by the scraper at a fixed angle, thereby avoiding to a large extent the damage of the substrate due to uneven force, and realizing scraping ink and drying at the same time, thereby avoiding to a large extent the damage of the pattern when the substrate is taken out, thereby overcoming the deficiencies in the prior art, and effectively solving the problem that the scraper body of the existing open and close scraper structure for screen printing cannot move at a fixed angle during the scraping process, if the angle of the scraper body cannot be kept stable, the substrate is easily damaged due to uneven force, and in the process of scraping ink, the ink remaining on the substrate cannot be dried, which easily causes the pattern to be damaged when the printed substrate is taken out.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A printing scraper structure comprises a printing platform, a screen frame is placed on the top of the printing platform, a moving component is slidably connected to the screen frame, a scraper component is installed on the moving component, an angle adjustment component used in conjunction with the scraper component and the moving component is installed on the scraper component, and a drying component is connected to the scraper component;

[0010] The scraper assembly comprises a rotating rod, and a scraper is fixed on the outer wall of the rotating rod.

[0011] Through the above-mentioned scheme, by using the coordinated use of the movable component, the scraper component, the angle adjustment component and the drying component, the scraper can scrape the ink stably at a fixed angle, which largely avoids the damage of the substrate due to uneven force, and achieves scraping and drying at the same time, which largely avoids the damage of the pattern when taking the substrate.

[0012] Preferably, the moving assembly comprises two U-shaped sliders, which are respectively slidably engaged with two sides of the screen frame, and a connecting rod is fixed between the two U-shaped sliders.

[0013] Preferably, both ends of the rotating rod are rotatably connected to two U-shaped sliders via bearings, and the rotating rod is located below the connecting rod.

[0014] Preferably, the angle adjustment assembly includes two support rods fixed at one end of the rotating rod, arc rods are fixed on the two support rods, and holes are opened at equal distances on the surface of the arc rods. A U-shaped rod is fixed to one side of the upper end surface of the rotating rod, and a fixing pin is inserted in the horizontal section of the U-shaped rod, and the bottom end of the fixing pin forms a plug-in fit with the hole.

[0015] Preferably, the drying component includes an air outlet duct fixed between two U-shaped sliders, one end of the air outlet duct is connected to a hose, a fan is fixed on the side of the printing table, an electric heating wire is fixed to the inner wall of the air inlet end of the fan, one end of the hose is connected to the air outlet end of the fan, and air outlet holes are evenly arranged on the air outlet duct.

[0016] Preferably, the surface of the connecting rod is provided with anti-slip grooves, and both sides of the bottom end of the scraper are provided with chamfered structures.

[0017] The beneficial effects of the utility model are:

[0018] 1. Place the substrate on the printing table, turn the scraper to drive the rotating rod to rotate, adjust the scraper to an inclined angle, and then insert the fixing pin into the socket to fix the scraper. Turn the connecting rod to drive the two U-shaped sliders to move on the screen frame, and then drive the scraper to move at a stable angle to scrape ink, which greatly avoids damage to the substrate due to uneven force.

[0019] 2. By turning on the fan and the electric heating wire, the fan blows hot air into the air outlet duct, and the hot air is blown out from the air outlet holes of the air outlet duct, so that the ink can be scraped and dried at the same time, which largely avoids the situation where the pattern is damaged when taking the printed material.

[0020] To sum up, through the coordinated use of the moving component, scraper component, angle adjustment component and drying component, the scraper can scrape the ink stably at a fixed angle, which greatly avoids the damage of the substrate due to uneven force, and achieves scraping and drying at the same time, which greatly avoids the damage of the pattern when taking the substrate.
