Description

Technical Field

[0001] The utility model relates to the field of watercolor pen production, in particular to an ink filling device for a watercolor pen. Background Art

[0002] Watercolor pens are a tool for children to draw. Watercolor pens are usually sold in boxes of multiple pens, and each watercolor pen has a different color.

[0003] In the current existing technology, when producing watercolor pens, workers need to inject ink into the pen barrel through an ink filling device. The ink filling device generally extracts ink from the ink cartridge through a piston cylinder or a micro pump and injects it into the pen barrel through an ink filling tube. For the purpose of aesthetics, the pen barrel of the watercolor pen is designed to be made of transparent plastic material. At the same time, some fluorescent powder and some decorative powder are added and mixed into the ink. The decorative powder is mainly used to improve the aesthetics of the watercolor pen, and the fluorescent powder is used to provide some fluorescent effects for the painted pattern to improve the aesthetics.

[0004] However, when refilling ink, the fluorescent powder and decorative powder in the ink will precipitate, which will cause uneven distribution of the fluorescent powder and decorative powder in the ink. In particular, for safety reasons, when using safer water-based ink, the viscosity of water-based ink is lower, and the fluorescent powder and decorative powder are more likely to precipitate, resulting in different contents of fluorescent powder and decorative powder in each watercolor pen after refilling. Therefore, a watercolor pen refilling device is proposed to address the above problems. Utility Model Content

[0024] When in use, the staff injects ink from the ink fountain into the ink cartridge 15, and then fixes the pen holder to the bottom of the frame 11 through a fixing fixture, and then starts the electric push rod 12, which drives the sliding block 13 and the ink injection tube 25 to move downward, so that the ink injection tube 25 is inserted into the pen holder of the watercolor pen, and then starts the servo motor 16, which starts the stirring shaft 17 to rotate, and the stirring shaft 17 and the stirring impeller 18 rotate, so that the fluorescent powder and the decorative powder in the ink are mixed. Relying on the above-mentioned setting, the ink in the ink cartridge 15 is stirred and mixed once before each ink injection, thereby reducing the precipitation of the fluorescent powder and the decorative powder, thereby reducing the fluorescent powder and the decorative powder in the injected ink. In order to solve the problem of uneven amount of fluorescent powder and improve the uniformity of the content of fluorescent powder and decorative powder in the ink of each watercolor pen, during use, the stirring shaft 17 will drive the screw 21 to rotate through the synchronous belt, and the rotation of the screw 21 will drive the first rod 22 and the second rod 23 to move downward, and then push the piston rod 27 to move downward, so as to inject the ink in the piston cylinder 24 into the pen body, and then the servo motor 16 drives the screw 21 to rotate in the opposite direction through the synchronous belt, and then the first rod 22 and the second rod 23 pull the piston rod 27 to move upward, and the piston rod 27 extracts ink from the ink cartridge 15 through the connecting tube 26, and the piston rod 27 is connected to the bottom end of the second rod 23, and the one-way valve is used to make the ink in the ink injection tube 25 and the connecting tube 26 flow in one direction.

When in use, the staff can heat the ink cartridge 15 through the electric heating plate 52 to increase the temperature of the ink cartridge 15 and then ensure the fluidity of the ink. The insulating sleeve 51 is used to keep warm.

[0028] Further, such as Figure 2 As shown, a connecting ring is fixedly connected to the top of the stirring shaft 17; a plurality of scraping rods 6 are fixedly connected to the surface of the connecting ring; the scraping rods 6 are L-shaped rods; when in use, the rotation of the stirring shaft 17 drives the scraping rods 6 to rotate along the inner wall of the ink cylinder 15, thereby scraping off the ink adhered to the inner wall of the ink cylinder 15, so as to facilitate mixing with other inks and improve the overall mixing uniformity.

During use, the stirring shaft 17 drives the screw rod 21 to rotate through the synchronous belt, and the rotation of the screw rod 21 drives the first rod body 22 and the second rod body 23 to move downward, thereby pushing the piston rod 27 downward, so as to inject the ink in the piston cylinder 24 into the pen body, and then the servo motor 16 drives the screw rod 21 to rotate in the opposite direction through the synchronous belt, and then the first rod body 22 and the second rod body 23 pull the piston rod 27 upward, and the piston rod 27 is pulled from the ink cylinder 24 through the connecting pipe 26. Ink is extracted from the cylinder 15, and the piston rod 27 is connected to the bottom end of the second rod body 23. The one-way valve is used to make the ink in the ink injection tube 25 and the connecting tube 26 flow in one direction. The staff can rotate the screw 31 according to the demand for the ink injection amount. The rotation of the screw 31 will drive the piston rod 27 to move, thereby adjusting the length of the piston rod 27 that can slide in the piston cylinder 24, and then adjust the ink injection amount to improve the scope of application. The spring 32 is used to adjust the length of the first rod body 22 and the second rod body 23 to adapt to the adjusted piston rod 27. The slide rail 41 is used to improve the movement stability of the sliding block 13, thereby improving the up and down movement of the ink injection tube 25. The stability of movement can facilitate the insertion of the ink filling tube 25 into the pen holder of the watercolor pen to facilitate ink filling. In some cold areas, due to the low temperature, the low temperature will cause the fluidity of the ink to decrease, and in severe cases, it will also cause gelation. When in use, the staff can heat the ink cylinder 15 through the electric heating plate 52 to increase the temperature of the ink cylinder 15 and thus ensure the fluidity of the ink. The insulation sleeve 51 is used to play a role in heat preservation. The rotation of the stirring shaft 17 will drive the scraper 6 to rotate along the inner wall of the ink cylinder 15, so as to scrape off the ink adhered to the inner wall of the ink cylinder 15, so as to mix it with other inks and improve the overall mixing uniformity.
