Description

Technical Field

[0001] This application relates to the field of screen printing technology, and more particularly to a screen printing apparatus with accurate alignment. Background Technology

[0002] A screen printing apparatus is a mechanical device that uses a screen as a printing plate base, and creates a screen printing plate with images and text through a photosensitive plate-making method, for printing. A screen printing apparatus consists of five main components: the screen printing plate, the squeegee, the ink, the printing table, and the printing substrate.

[0003] Currently, traditional screen printing equipment uses a squeegee to apply pressure to the ink on the screen printing plate, causing the ink to pass through the mesh of the image area of ​​the screen printing plate and be transferred to the substrate. However, when printing different patterns, it is not possible to quickly change the screen printing plate, resulting in reduced printing efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a screen printing device with accurate alignment, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a screen printing device with accurate alignment, comprising a base, a placement platform fixedly connected to the top of the base, a height adjustment mechanism on one side of the placement platform, a moving mechanism on one side of the height adjustment mechanism, a moving rod slidably connected to the surface of the moving mechanism, a storage box fixedly connected to the top of the moving rod, a stirring mechanism inside the storage box, a conveying mechanism on one side of the stirring mechanism, two angle adjustment mechanisms symmetrically distributed on the surface of the moving rod, a screen printing plate on the top of the placement platform, a rotating mechanism on one side of the screen printing plate, the rotating mechanism including a motor, the motor fixedly connected to the base, a rotating frame fixedly connected to the output end of the motor, a positioning frame rotatably connected inside the rotating frame, and bolts threadedly connected to the surface of the positioning frame.

[0006] In a preferred embodiment, the height adjustment mechanism includes a support frame, which is fixedly connected to the base. A motor is fixedly connected to the top of the support frame, and a threaded rod is fixedly connected to the output end of the motor. The threaded rod is rotatably connected to the support frame.

[0007] By adopting the above technical solution, the motor is fixed by the support frame, and the output end of the motor drives the threaded rod to rotate, which can better enable the threaded rod to rotate inside the support frame.

[0008] In a preferred embodiment, the moving mechanism includes a moving frame, which is threadedly connected to a threaded rod and slidably connected to a support frame. A second motor is fixedly connected to the surface of the moving frame, and a second threaded rod is fixedly connected to the output end of the second motor. The second threaded rod is rotatably connected to the moving frame, threadedly connected to a moving rod, and slidably connected to the moving frame.

[0009] By adopting the above technical solution, the second motor is fixed by the movable frame, and the output end of the second motor rotates to drive the second threaded rod to rotate. The rotation of the second threaded rod then causes the movable rod to move on the surface of the movable frame, which can better enable the movable rod to move on the surface of the movable frame.

[0010] In a preferred embodiment, the stirring mechanism includes a motor three, the output end of which is fixedly connected to a rotating rod, the rotating rod being rotatably connected to a storage tank, and a stirring blade being fixedly connected to the surface of the rotating rod.

[0011] By adopting the above technical solution, the output end of motor three drives the rotating rod to rotate, which in turn drives the stirring blade to rotate, and the stirring blade to stir the coating inside the storage tank, preventing the coating inside the storage tank from separating or solidifying. This allows for better stirring of the coating inside the storage tank and prevents the coating inside the storage tank from separating or solidifying.

[0012] In a preferred embodiment, the conveying mechanism includes a pump body, which is fixedly connected to a moving rod. The input of the pump body is fixedly connected to a storage tank. A conveying pipe is fixedly connected to the side of the pump body away from the storage tank, and a discharge port is fixedly connected to the end of the conveying pipe away from the pump body.

[0013] By adopting the above technical solution, the paint inside the storage tank is drawn into the conveying pipe by the pump body, and then the paint is conveyed to the outlet by the conveying pipe and discharged from the outlet. This can better convey the paint inside the storage tank.

[0014] In a preferred embodiment, the angle adjustment mechanism includes a fixed frame, which is fixedly connected to a movable rod. An electric push rod is fixedly connected to the surface of the fixed frame, and a scraper is rotatably connected to the telescopic end of the electric push rod. The scraper is rotatably connected to the movable rod.

[0015] By adopting the above technical solution, the electric push rod is fixed by the fixing frame, and the extension and retraction of the electric push rod drives the scraper to adjust the angle. The scraper then scrapes the paint so that the paint is evenly covered on the surface of the screen printing plate, which can better adjust the angle of the scraper.

[0016] In a preferred embodiment, a controller is fixedly connected to the surface of the base, and a photoelectric sensor is fixedly connected to the surface of the moving rod. The controller is electrically connected to the photoelectric sensor and the motor.

[0017] By adopting the above technical solution, the relative positional deviation between the screen printing plate and the substrate is monitored in real time by a photoelectric sensor, and the switch of motor four is controlled by the controller, which can better detect the relative positional deviation between the screen printing plate and the substrate.

[0018] In a preferred embodiment, a spring is provided between the rotating frame and the positioning frame.

[0019] By adopting the above technical solution, a spring is provided between the rotating frame and the positioning frame. After printing is completed, the spring will support the positioning frame, so that the screen printing plate can be separated from the surface of the substrate, which can better separate the screen printing plate from the surface of the substrate.

[0020] The beneficial effects of this application are:

[0021] 1. This screen printing device with accurate alignment features a motor, a rotating frame, a positioning frame, and bolts. Rotating the bolts causes them to engage with the screen printing plate, securing it within the positioning frame. To replace the screen printing plate, the motor is activated, rotating the rotating frame and then the screen printing plate and positioning frame, allowing for plate replacement. This design avoids the problem of traditional screen printing devices, which cannot quickly replace the screen printing plate when printing different patterns, leading to reduced printing efficiency and improving practicality.

[0022] 2. This screen printing device with accurate alignment, by setting up a motor, a stirring blade, and a rotating rod, the output end of the motor drives the rotating rod to rotate, which in turn drives the stirring blade to rotate, and the stirring blade to stir the paint inside the storage tank, preventing the paint inside the storage tank from separating or solidifying. This avoids the problem that traditional screen printing devices cannot stir the paint inside the storage tank, thus improving practicality. Attached Figure Description

[0032] Reference Figures 1-3 A conveying mechanism 6 is provided on one side of the stirring mechanism 5.

[0036] Reference Figure 4 A spring is provided between the rotating frame 72 and the positioning frame 73. With the spring between the rotating frame 72 and the positioning frame 73, after printing is completed, the spring will support the positioning frame 73, so that the screen printing plate 8 can be separated from the surface of the substrate, which can better separate the screen printing plate 8 from the surface of the substrate.

[0037] Working principle: The paint is poured into the storage tank 9, and the substrate is placed on the surface of the placement table 12. The support frame 22 fixes the motor 21. The output end of the motor 21 rotates, driving the threaded rod 23 to rotate, adjusting the height of the scraper 41. The scraper 41 then contacts the screen printing plate 8, making the screen printing plate 8 adhere tightly to the surface of the substrate. The output end of the motor 51 rotates, driving the rotating rod 53 to rotate, which in turn drives the stirring blade 52 to rotate. The stirring blade 52 then stirs the paint inside the storage tank 9, preventing the paint from separating or solidifying. The pump body 61 then draws the paint from the storage tank 9 into the delivery pipe 62, which then transports the paint to the outlet 63. The paint is then discharged from the outlet 63 onto the surface of the screen printing plate 8. Finally, the fixing frame 43... The electric push rod 42 is fixed, and the extension and retraction of the electric push rod 42 drives the scraper 41 to adjust its angle. The moving frame 31 then fixes the motor 32. The output end of the motor 32 rotates, driving the threaded rod 33 to rotate. The rotation of the threaded rod 33 causes the moving rod 10 to move on the surface of the moving frame 31, thereby driving the scraper 41 to move. The scraper 41 then scrapes the paint, making the paint evenly cover the surface of the screen printing plate 8. The rotating bolt 74 is then inserted into the interior of the screen printing plate 8, fixing the screen printing plate 8 inside the positioning frame 73. When the screen printing plate 8 needs to be replaced, the motor 71 is started. The output end of the motor 71 rotates, driving the rotating frame 72 to rotate. The rotation of the rotating frame 72 then drives the screen printing plate 8 and the positioning frame 73 to rotate, allowing the screen printing plate 8 to be replaced.
