Description

Technical Field

[0001] The utility model belongs to the field of printing ink production equipment, and particularly relates to a printing ink impurity filtering device. Background Art

[0002] Ink is a homogeneous mixture composed of coloring substances (such as pigments, dyes, etc.), binders, fillers, additives, etc.; it can be printed and dried on the printed object; it is a paste-like adhesive with color and a certain fluidity. In the production process of printing ink, after the mixture of powdery raw materials and binders, since impurities may be mixed into the powdery raw materials, the mixing of impurities during the production process will affect the color of the pigment. Therefore, impurity screening during the production process can improve the quality of the produced products. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a printing ink impurity filtering device. By placing the mixture in the feeding cylinder, the mixture is introduced into the filtering component by gravity. The cylinder drives the push plate to reciprocally push the mixture on the screen. The sufficiently refined mixture penetrates the screen and accumulates in the receiving bucket at the lower end, while the impurities that cannot pass through the screen stay on the screen, realizing the filtration of printing ink.

[0004] To achieve the above object, the technical solution adopted by the utility model is:

[0005] A printing ink impurity filtering device includes a frame, a feeding cylinder, a filtering component, and a receiving bucket. The frame is sequentially connected from top to bottom by an upper support frame, a middle support frame, and a lower support frame. The feeding cylinder is sleeved in the upper support frame, and the receiving bucket is placed on the lower support frame.

[0006] The filtering component includes a screening cylinder, a screen, a cylinder, and a push plate. The screen is arranged in the screening cylinder. The screening cylinder is sleeved on the middle support frame. The upper opening of the screening cylinder points to the feeding cylinder, and the lower opening of the screening cylinder points to the receiving bucket. The cylinder is connected to the middle support frame, and the output end of the cylinder is connected to the push plate. The smoothing plate on the lower end surface of the push plate abuts against the screen, and the smoothing plate is made of silica gel material. A pipe sleeve is arranged on the push plate. The lower opening of the feeding cylinder is provided with a connector, and the lower end of the hose connected to the connector is nested in the pipe sleeve. A screw hole penetrating the inner cavity of the pipe sleeve is arranged on the pipe sleeve, and a screw is screwed in the screw hole. The end of the screw abuts against the hose. A limiting groove is arranged on the inner side surface of the screening cylinder, a limiting plate is arranged on the side surface of the push plate, a threaded hole is arranged on the limiting plate, and a stud is screwed in the threaded hole. The end of the stud is fitted in the limiting groove.

[0007] For the printing ink impurity filtering device adopting this structure, the feeding cylinder is used to store the unfiltered mixture, and the receiving barrel is used to hold the filtered mixture. In order to filter the impurities in the mixture, a filtering component is arranged between the feeding cylinder and the receiving barrel. The feeding cylinder, the receiving barrel and the filtering component are all arranged on the frame, and necessary supporting forces are provided by the upper support frame, the lower support frame and the middle support frame respectively. The filtering component includes a screening cylinder, a screen, a cylinder and a push plate. The screen is arranged inside the screening cylinder, and the upper opening of the screening cylinder points to the discharging place of the feeding cylinder. The mixture in the feeding cylinder falls onto the screen inside the screening cylinder. Due to the fluidity of the mixture, under the action of gravity, the mixture will pass through the screen and fall into the inner cavity of the screening cylinder. Screens corresponding to different particle sizes of the mixture can be set, so that the mixture can stay and filter the impurities with larger particle sizes on the screen during the process of passing through the screen.

[0008] Although the mixture itself has fluidity, its essence is relatively viscous. Relying solely on the action of gravity, it will take a long time for the mixture to penetrate through the screen, and it is also easy to have a large amount of mixture accumulated on the screen waiting to be filtered, which is not conducive to the daily production requirements. Therefore, a cylinder and a push plate are added. The cylinder is connected to the middle support frame, and the output end of the cylinder is connected to the push plate. The width of the push plate is the same as the upper opening of the screening cylinder. Therefore, driven by the cylinder, the push plate can move back and forth at the upper end of the screen. The smoothing plate at the lower end of the push plate sweeps horizontally on the screen surface, so that the mixture is accelerated to penetrate the screen under the push of the smoothing plate made of silica gel material, improving the filtering efficiency of the mixture. Since the push plate is directly connected to the output end of the cylinder, the push plate will rotate uncontrollably during the pushing process of the cylinder. The rotating push plate will continuously generate a downward pressure on one end of the screen, and the stressed end of the screen will be damaged after long-term operation. Therefore, a limiting groove is arranged on the side surface of the screening cylinder, and a limiting plate is arranged on the side surface of the push plate. By screwing a stud into the threaded hole on the limiting plate, the end of the stud is inserted into the limiting groove to cooperate with the limiting groove. Therefore, the push plate will be restricted in the limiting groove by the end of the stud during the pushing process, so that the push plate can only move horizontally, and the restricted push plate can push more horizontally on the screen, making the filtering of the mixture more balanced.

[0009] If the lower opening of the blanking cylinder directly points to the screen, the slowly falling mixture will drip onto the push plate, making it difficult to push the mixture. Therefore, a pipe sleeve is provided on the push plate, and an adapter is provided at the lower opening of the blanking cylinder. The lower end of the hose connected to the adapter is nested in the pipe sleeve. Thus, the mixture in the blanking cylinder can be directly introduced to the front end of the push plate through the hose. During the forward and backward movement of the push plate, the mixture can be continuously added in front of the push plate, avoiding the mixture directly dripping onto the push plate and ensuring that the mixture can be evenly and orderly added to the screen. To fix the hose, a screw is screwed into the screw hole on the pipe sleeve, and the bottom of the screw abuts against the hose to fix the hose and prevent the lower end of the hose from protruding excessively from the pipe sleeve.

[0010] Further, a joint penetrating the inner cavity is provided on the outer side wall of the screening cylinder, and the joint is connected to a vacuum pump; a baffle is provided in the screening cylinder, and the baffle is horizontally arranged at the connection between the joint and the screening cylinder.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: The mixture after mixing the powdery raw material and the connecting material is directly introduced to the front end of the push plate through the hose under the adapter. During the forward and backward movement of the push plate, the mixture is continuously added in front of the push plate, avoiding the mixture directly dripping onto the push plate and ensuring that the mixture can be evenly and orderly added to the screen. Due to the fluidity of the mixture, under the action of gravity, the mixture will pass through the screen and fall into the inner cavity of the screening cylinder. Screens corresponding to different particle sizes of the mixture can be set. Thus, during the process of the mixture passing through the screen, impurities with larger particle sizes can be retained and filtered on the screen. At the same time, the flat plate under the push plate accelerates the mixture to penetrate the screen, improving the filtering efficiency. To fix the hose, a screw is screwed into the screw hole on the pipe sleeve, and the bottom of the screw abuts against the hose to fix the hose and prevent the lower end of the hose from protruding excessively from the pipe sleeve.

[0023] Description of the working mode of the present utility model:

[0024] For the printing ink impurity filtering device adopting this structure, the feeding cylinder 2 is used to store the mixture that has not been filtered, and the receiving barrel 4 is used to receive the filtered mixture. In order to filter the impurities in the mixture, a filtering component 3 is arranged between the feeding cylinder 2 and the receiving barrel 4. The feeding cylinder 2, the receiving barrel 4 and the filtering component 3 are all arranged on the frame 1, and necessary supporting forces are respectively provided by the upper support frame 11, the lower support frame 13 and the middle support frame 12. The filtering component 3 includes a screening cylinder 31, a screen 32, a cylinder 33 and a push plate 34. The screen 32 is arranged inside the screening cylinder 31, and the upper opening of the screening cylinder 31 points to the discharging place of the feeding cylinder 2. The mixture in the feeding cylinder 2 falls on the screen 32 inside the screening cylinder 31. Due to the fluidity of the mixture, under the action of gravity, the mixture will pass through the screen and fall into the inner cavity of the screening cylinder 31. Screens 32 corresponding to different particle sizes of the mixture can be set, so that the mixture can stay and filter the impurities with larger particle sizes on the screen 32 during the process of passing through the screen 32.

[0025] Although the mixture itself has fluidity, its nature is relatively viscous. Relying solely on the action of gravity, it takes a long time for the mixture to penetrate through the screen 32, and it is also easy to have a large amount of mixture accumulated on the screen 32 waiting to be filtered, which is not conducive to the daily production requirements. Therefore, a cylinder 33 and a push plate 34 are added. The cylinder 33 is connected to the middle support frame 12, and the output end of the cylinder 33 is connected to the push plate 34. The width of the push plate 34 is the same as the upper opening of the screening cylinder 31. Therefore, driven by the cylinder 33, the push plate 34 can move back and forth at the upper end of the screen 32. The smoothing plate 341 at the lower end of the push plate 34 sweeps horizontally on the surface of the screen 32, so that the mixture is accelerated to penetrate the screen 32 under the push of the smoothing plate 341 made of silica gel material, improving the filtering efficiency of the mixture. Since the push plate 34 is directly connected to the output end of the cylinder 33, the push plate 34 will rotate uncontrollably during the pushing process of the cylinder 33. The rotating push plate 34 will continuously generate a downward pressure on one end of the screen 32, and the stressed end of the screen 32 will be damaged after long-term operation. Therefore, a limiting groove 311 is provided on the side surface of the screening cylinder 31, and a limiting plate 344 is provided on the side surface of the push plate 34. By screwing a stud into the threaded hole 345 on the limiting plate 344, the end of the stud is inserted into the limiting groove 311 to cooperate with the limiting groove 311. Therefore, the push plate 34 will be restricted in the limiting groove 311 by the end of the stud during the pushing process, so that the push plate 34 can only move horizontally, and the restricted push plate 34 can push more horizontally on the screen 32, making the filtering of the mixture more balanced.

[0026] If the lower opening of the feeding cylinder 2 is directly pointed at the screen 32, the slowly falling mixture will drip on the push plate 34, causing difficulty in pushing the mixture. Therefore, a pipe sleeve 342 is provided on the push plate 34, and a connector 21 is provided at the lower opening of the feeding cylinder 2. The lower end of the hose 22 connected to the connector 21 is nested in the pipe sleeve 342. Therefore, the mixture in the feeding cylinder 2 can be directly introduced to the front end of the push plate 34 through the hose 22. During the forward and backward movement of the push plate 34, the mixture can be continuously added in front of the push plate 34, avoiding the mixture directly dripping on the push plate 34 and ensuring that the mixture can be evenly and orderly added to the screen 32. In order to fix the hose 22, a screw is screwed into the screw hole 343 on the pipe sleeve 342, and the bottom of the screw abuts against the hose 22 to fix the hose 22 and prevent the lower end of the hose 22 from protruding excessively from the pipe sleeve 342.

[0027] Even when the push plate 34 is combined with the leveling plate 341 and a hose 22 is added to ensure the orderly addition of the mixture, it may still occur that the filtration rate of the mixture is not fast enough. Therefore, a connector 312 can be provided on the side wall of the screening cylinder 31 at the lower end of the screen 32, and this connector 312 is connected to a vacuum pump. Since the mixture on the screen 32 will ultimately fill the entire upper end face of the screen 32 due to filtration efficiency issues, the space below the screen 32 is connected to the vacuum pump, and a one-way valve is provided at the lower end opening of the screening cylinder 31 to ensure that after the upper end of the screen 32 is completely covered with the mixture, the lower end of the screen 32 is in a sealed space. Therefore, the intervention of the vacuum pump can accelerate the mixture passing through the screen 32 through the suction of the vacuum, accelerating filtration. To prevent the mixture dripping from the screen 32 from entering the connector 312, a baffle 313 is provided in the screening cylinder 31, and the baffle 313 is horizontally placed to block the connection between the connector 312 and the screening cylinder 31, preventing the mixture from dripping into the connector 312 and also ensuring the vacuum effect; furthermore, a nozzle can be added to the lower end face of the push head. When the leveling plate 341 moves on the screen 32, air can be sprayed downward onto the screen 32 through the nozzle to assist in accelerating the mixture passing through the screen 32 and improving the filtration efficiency.

[0028] The beneficial effects of the present utility model are as follows: The mixture after mixing the powdery raw material and the binder is directly introduced to the front end of the push plate 34 through the hose 22 under the adapter 21. During the forward and backward movement of the push plate 34, the mixture is continuously added in front of the push plate 34, avoiding the mixture directly dripping onto the push plate 34 and also ensuring that the mixture can be evenly and orderly added to the screen 32. Since the mixture has fluidity, under the action of gravity, the mixture will pass through the screen and fall into the inner cavity of the screening cylinder 31. Screens 32 corresponding to different particle sizes of the mixture can be set. Thus, during the process of the mixture passing through the screen 32, impurities with larger particle sizes can be retained and filtered on the screen 32. At the same time, the leveling plate 341 under the push plate 34 accelerates the mixture to penetrate through the screen 32, improving the filtration efficiency. To fix the hose 22, a screw is screwed into the screw hole 343 on the pipe sleeve 342, and the bottom of the screw abuts against the hose 22 to fix the hose 22 and prevent the lower end of the hose 22 from protruding excessively from the pipe sleeve 342.

[0029] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present utility model.
