[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] The present embodiment provides a raw material adding device for UV ink production.

The material guide plate 3, the screening component 4, the discharge hopper 8, the discharge hose 9 and the discharge port 10 are used in coordination with each other, thereby facilitating the screening of the powdered raw materials during the process of adding them to the ink mixing tank 12, so that the ink is stirred evenly to avoid local color differences, ensure good appearance, and not cause viscosity abnormalities, thereby ensuring good printing effects and normal drying speed.

[0023] See also Figures 1 to 5 A raw material adding device for UV ink production includes a shell 1, a feed hopper 2 is provided on the top of the shell 1, and a guide plate 3 is fixedly connected to the inner wall of the shell 1.

[0024] The guide plate 3 is designed to be inclined. The powdered raw materials are poured into the shell 1 through the feed hopper 2. The raw materials are introduced into the screening plate 401 through the guide plate 3, thereby achieving a guiding effect on the raw materials.

[0025] A screening assembly 4 is provided inside the housing 1 .

[0026] The screening assembly 4 comprises a screening plate 401 slidably connected to the inner wall of the housing 1 .

[0027] The inner wall of the screening plate 401 is rotatably connected to the limiting shaft 402 , and the outer surface of the limiting shaft 402 is fixedly connected to the inner wall of the shell 1 .

[0028] By setting the limiting shaft 402, the screening plate 401 can be limited, and the screening plate 401 can be restricted to rotate around the limiting shaft 402 as the axis during movement, thereby avoiding the deviation of the screening plate 401 during movement, thereby ensuring the stability of the screening plate 401 when screening materials, and achieving a better screening effect.

[0029] A shaking mechanism 5 is provided inside the housing 1 .

[0030] The shaking mechanism 5 includes a motor 501 fixedly mounted on the outer surface of the shell 1. The output end of the motor 501 is fixedly connected to a rotating shaft 502, and the outer surface of the rotating shaft 502 rotates with the inner wall of the shell 1. The end of the rotating shaft 502 away from the motor 501 is fixedly connected to a cam 503.

[0031] The inner wall of the cam 503 is rotatably connected to the movable shaft 1 504 , the outer surface of the movable shaft 1 504 is rotatably connected to the connecting plate 505 , the inner wall of the connecting plate 505 is rotatably connected to the movable shaft 2 506 , and the outer surface of the movable shaft 2 506 is rotatably connected to the connecting frame 507 .

[0032] The movable shaft 1 504 and the movable shaft 2 506 can provide movable space for the cam 503 and the connecting plate 505 during movement to avoid jamming, and can cooperate with the limit block 6 to ensure the vertical movement of the push rod 508.

[0033] A top rod 508 is fixedly connected to the top of the connecting frame 507 . The outer surface of the top rod 508 slides with the inner wall of the limiting block 6 , and the top of the top rod 508 contacts the bottom of the screening plate 401 .

[0034] Turn on the motor 501, and the motor 501 will drive the rotating shaft 502 to rotate, and then the rotating shaft 502 will drive the cam 503 to rotate accordingly, and the cam 503 will drive the movable shaft 1 504 to rotate with the rotating shaft 502 as the axis. At this time, the movable shaft 1 504 will drive the connecting plate 505, the movable shaft 2 506, the connecting frame 507 and the push rod 508 to move downward, thereby making the screening plate 401 on the top of the push rod 508 rotate clockwise with the limiting shaft 402 as the axis. When the rotating shaft 502 drives the cam 503 and the movable shaft 1 504 to rotate 180 degrees, the bottom of the screening plate 401 will contact the buffer pad 7. When the cam 503 continues to rotate, it will drive the connecting plate 505, movable shaft 2 506, connecting frame 507 and push rod 508 to move gradually upward. After the cam 503 rotates 360 degrees, movable shaft 1 504 will drive the connecting plate 505, movable shaft 2 506, connecting frame 507 and push rod 508 to move upward to the highest point. At this time, the push rod 508 will drive the screening plate 401 to rotate counterclockwise with the limiting shaft 402 as the axis to reach the highest point. This cycle will be repeated, so that the screening plate 401 can continue to flip up and down with the limiting shaft 402 as the axis, so that the powdered raw materials on the screening plate 401 can be screened.

[0035] The inner wall of the housing 1 is fixedly connected to a limit block 6 , and the top of the limit block 6 is fixedly connected to a buffer pad 7 .

[0036] The limit block 6 can limit the top rod 508, ensure the stable vertical movement of the top rod 508, and improve the stability of the top rod 508 during movement. The buffer pad 7 can be designed to be made of rubber. The buffer pad 7 can protect the bottom of the screening plate 401 to prevent the impact force generated by the screening plate 401 and the limit block 6 from causing excessive collision to the screening plate 401 and accelerating wear.

[0037] Screening holes 403 are formed inside the screen plate 401 .

[0038] A discharge hopper 8 is provided at the bottom of the housing 1 .

[0039] An ink mixing tank 12 is provided below the discharge hose 9 .

[0040] Qualified materials in the powdered raw materials can be screened out through the screening holes 403 , the qualified materials can be guided through the discharge hopper 8 , and finally the qualified materials can be added into the ink mixing tank 12 through the discharge hose 9 .

[0041] The bottom of the discharge hopper 8 is fixedly connected with a discharge hose 9.

[0042] The discharge hose 9 can be designed as a bellows with strong telescopic deformation capability, which can facilitate the addition of qualified materials into the ink mixing tank 12 through the discharge hose 9.

[0043] The bottom of the housing 1 is provided with a debris discharge port 10 .

[0044] A through slot 404 is formed inside the screening plate 401 .

[0045] Unqualified materials will fall through the through slot 404 and finally be discharged into the collection bucket through the impurity discharge port 10.

[0046] A supporting leg 11 is fixedly connected to the outer surface of the housing 1 .

[0047] Working principle: When the present invention is in use, the ink mixing tank 12 needs to be placed just below the discharge hose 9, and the discharge hose 9 is extended into the feed port of the ink mixing tank 12, so as to facilitate the subsequent addition of screened powdered materials into the ink mixing tank 12, and the powdered raw materials are poured into the shell 1 through the feed hopper 2, and the raw materials are introduced into the screening plate 401 through the guide plate 3, and then the powdered raw materials are accumulated on the screening plate 401, and then the motor 501 needs to be turned on by the external controller, at this time the motor 501 will drive the rotating shaft 502 to rotate, and then the rotating shaft 502 will drive the cam 503 to rotate, and the cam 503 will drive the movable shaft 504 to rotate with the rotating shaft 50 2 is the axis to rotate, at this time the movable shaft 1 504 will drive the connecting plate 505, the movable shaft 2 506, the connecting frame 507 and the top rod 508 to move downward, thereby making the screen plate 401 on the top of the top rod 508 rotate clockwise with the limit shaft 402 as the axis. When the rotating shaft 502 drives the cam 503 and the movable shaft 1 504 to rotate 180 degrees, the bottom of the screen plate 401 will contact the buffer pad 7. At this time, the buffer pad 7 can protect the bottom of the screen plate 401, avoiding the impact force generated by the screen plate 401 and the limit block 6 to cause excessive collision to the screen plate 401 and accelerate wear. When the cam 503 continues to rotate, it will drive the connecting plate 505, the movable shaft 2 506, connecting frame 507 and push rod 508 gradually move upward. When cam 503 rotates 360 degrees, movable shaft 1 504 will drive connecting plate 505, movable shaft 2 506, connecting frame 507 and push rod 508 to move upward to reach the highest point. At this time, push rod 508 will drive screening plate 401 to rotate counterclockwise around limit shaft 402 to reach the highest point. This cycle is repeated, so that screening plate 401 can continuously flip up and down around limit shaft 402, so that powdered raw materials on screening plate 401 can be screened. The continuous flipping of screening plate 401 will drive powdered raw materials to gradually move to the left, and the powdered raw materials can be screened through screening holes 403. Qualified materials in the raw materials are screened out, and the qualified materials can be guided by the discharge hopper 8, and finally the qualified materials are added into the ink mixing tank 12 through the discharge hose 9. At the same time, unqualified materials will fall through the through groove 404, and finally the unqualified materials are discharged into the collection bucket through the discharge port 10. The guide plate 3, screening component 4, discharge hopper 8, discharge hose 9 and discharge port 10 are used in conjunction with each other, so that the powdered raw materials can be screened during the process of being added to the ink mixing tank 12, so that the ink is evenly stirred to avoid local color differences, ensure good appearance, and will not cause viscosity abnormalities, ensuring good printing effects and normal drying speed.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
