Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a curved surface screen printing component capable of preventing ink from settling. Background Art

[0002] Screen printing is a process of printing based on the basic principle that the mesh holes of the graphic part of the screen printing plate are permeable to ink, while the mesh holes of the non-graphic part are not. When printing, ink is poured into one end of the screen printing plate, and a scraper is used to apply a certain pressure to the ink part of the screen printing plate while moving the screen printing plate at a constant speed toward the other end. During the movement, the ink is squeezed from the mesh holes of the graphic part onto the substrate by the scraper. Curved screen printing is when the substrate has an unusual curved shape, such as curved structures such as barrels, cans, and bottles of packaging materials.

[0003] A green curved screen printing component with application number 202120313671.9 includes an ink storage cartridge, a box cover is provided on the top of the ink storage cartridge, a motor box is provided in the middle of the top of the box cover, a motor is provided in the motor box, a rotating shaft is provided at the output end of the bottom of the motor, the bottom end of the rotating shaft passes through the box cover and is provided in the ink storage cartridge, a stirring rod is provided on the outside of the rotating shaft, and the stirring rod is provided in the ink storage cartridge, a feed pipe is provided on the left side of the top of the box cover, a discharge pipe is provided in the middle of the bottom of the ink storage cartridge, and an electric heating plate is provided on the outside of the ink storage cartridge. The utility model has a simple structure and a reasonable design. After the printing ink is stored in the ink storage cartridge, the ink is stirred by the stirring rod to prevent the ink from precipitating, and the hot air can be directed to the heating tank to prevent the ink temperature from being low, thereby ensuring the printing effect.

[0004] This technical solution stirs the ink by a rotating stirring rod to avoid precipitation, but during use, it is necessary to power the motor to drive the stirring rod to rotate, which increases the cost and energy consumption of screen printing. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a curved screen printing component that prevents ink precipitation, so as to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a curved screen printing component that prevents ink precipitation, including a mounting frame and a shell, characterized in that: guide seats are connected to both sides of the interior of the shell, a stirring shaft is connected to the interior of the shell, and a stirring blade is connected to the outer surface of the stirring shaft, a clockwork spring is sleeved on the outside of the stirring shaft, a winding wheel is connected to one side of the stirring shaft, and a pull rope is connected to the bottom of the winding wheel.

[0007] By adopting the above technical solution, when the ink is scraped into the holes of the screen by the scraper, the scraper moves away from the shell to pull the pull rope, and after the pull rope is pulled, the take-up wheel is pulled and rotated to release the pull rope, and at the same time, the rotation of the take-up wheel drives the stirring blade to rotate through the stirring shaft, thereby stirring the ink in the shell to prevent sedimentation, and the clockwork spring is compressed; when the scraper is reset after printing, the pull rope is no longer pulled. At this time, the clockwork spring drives the stirring shaft and the stirring blade to reverse, stirring the ink again to prevent sedimentation, and the stirring shaft drives the take-up wheel to reverse to reel in the loose pull rope, ready to move down for stirring.

[0008] Furthermore, the cross section of the stirring blade is in a "T" shape.

[0009] By adopting the above technical solution, since the cross section of the stirring blade is T-shaped, the ink can be effectively stirred regardless of whether it rotates forward or reversely to avoid precipitation.

[0010] Furthermore, a plurality of stirring blades are provided, and the plurality of stirring blades are distributed in a ring array.

[0011] By adopting the above technical solution, the number of stirring blades is increased to increase the stirring range, thereby effectively avoiding the occurrence of ink precipitation.

[0012] Furthermore, the pull rope is a steel wire rope.

[0013] By adopting the above technical solution, the pull rope made of steel wire rope has the advantages of high structural strength and long service life, and can fully transmit the pulling force to rotate the stirring shaft and the stirring blade.

[0014] Furthermore, there are two winding wheels, two pull ropes and two winding springs, and the two winding wheels, two pull ropes and two winding springs are symmetrically distributed.

[0015] By adopting the above technical solution, when the pull rope is pulled, the take-up wheel is pulled and rotated to release the pull rope. At the same time, the rotation of the take-up wheel drives the stirring blade to rotate through the stirring shaft, thereby stirring the ink in the shell to prevent precipitation.

[0016] Furthermore, a scraper is connected to the bottom end of the pull rope, a shell is connected to the top of the mounting frame, a cover plate is connected to the top of the shell, and a discharge valve is installed at the bottom of the shell.

[0017] By adopting the above technical solution, the staff opens the cover and pours the ink into the shell. Then the staff closes the cover. At this time, the ink is guided to the discharge valve through the guide seat. When the ink on the screen is exhausted, the staff can open the discharge valve to allow the ink in the shell to fall to the top of the screen.

[0018] Furthermore, the cover plate is detachably connected to the shell.

[0019] By adopting the above technical solution, the staff opens the cover and pours the ink into the shell, and then closes the cover to prevent foreign matter from falling into the ink.

[0020] Furthermore, an electric heating plate is installed at the lower part of the shell.

[0021] By adopting the above technical solution, the staff can turn on the electric heating plate to prevent the ink temperature from being too low, resulting in poor fluidity and difficulty in flowing out through the discharge valve.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a take-up wheel, a pull rope, a clockwork spring, a stirring shaft, a stirring blade and a guide seat. When the ink is scraped into the holes of the screen by the scraper, the scraper moves away from the shell to pull the pull rope. After the pull rope is pulled, the take-up wheel is pulled and rotated to release the pull rope. At the same time, the rotation of the take-up wheel drives the stirring blade to rotate through the stirring shaft, thereby stirring the ink in the shell to prevent sedimentation, and the clockwork spring is compressed by force. When the scraper is reset after printing, the pull rope is no longer pulled. At this time, the clockwork spring drives the stirring shaft and the stirring blade to reverse, and the ink is stirred again to prevent sedimentation. The stirring shaft drives the take-up wheel to reverse and reel in the loose pull rope, ready to move down for stirring. No additional control and electric drive are required, the structure is simple, the operation is convenient and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

There are two wheels 7, pull ropes 8 and springs 9, and the two winding wheels 7, pull ropes 8 and springs 9 are symmetrically distributed. When the staff scrapes the ink into the holes of the screen through the scraper 2, the scraper 2 moves away from the shell 3 to pull the pull rope 8. After the pull rope 8 is pulled, the winding wheel 7 is pulled and rotated to release the pull rope 8. At the same time, the rotation of the winding wheel 7 drives the stirring blade 11 to rotate through the stirring shaft 10, thereby stirring the ink in the shell 3 to prevent precipitation, and the spring 9 is compressed.

[0033] See also Figure 1-Figure 3 In the above embodiment, the scraper 2 is connected to the bottom end of the pull rope 8, the shell 3 is connected to the top of the mounting frame 1, the cover plate 4 is connected to the top of the shell 3, the cover plate 4 is detachably connected to the shell 3, and a discharge valve 5 is installed at the bottom of the shell 3. The staff opens the cover plate 4 and pours the ink into the shell 3. Then the staff closes the cover plate 4. At this time, the ink is guided to the discharge valve 5 through the guide seat 12. When the ink on the screen is exhausted, the staff can open the discharge valve 5 to allow the ink in the shell 3 to fall to the top of the screen.

[0034] Embodiment 2:

[0035] On the basis of the above-mentioned embodiment 1, in order to prevent the poor fluidity of ink from clogging the housing 3 due to low temperature, the following settings are now adopted.

[0036] See also Figure 2 and Figure 3 In the above embodiment, an electric heating plate 6 is installed at the lower part of the housing 3 , and the electric heating plate 6 is turned on to prevent the ink temperature from being too low, resulting in poor fluidity and difficulty in flowing out through the discharge valve 5 .
