Description

Technical Field

[0001] The utility model relates to the field of ink filling, in particular to a quantitative filling device for printing ink. Background Art

[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. Ink includes main ingredients and auxiliary ingredients, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. Ink is usually composed of resin, pigment, filler, additives and solvents.

[0003] In the prior art, after the ink is prepared into a finished product, it generally needs to be filled by a filling device. The current filling equipment often uses a filling head to fill the ink into a container. If there are many filling stations, multiple filling heads need to be configured for simultaneous filling. Conventional filling heads cannot adjust the spacing laterally, and cannot meet the user's needs for ink filling in containers of different sizes or shapes. In addition, after the filling head completes filling a batch of containers, some ink waste liquid will remain inside the filling head. At this time, the filling head needs to be emptied, and the printing ink will splash into the surrounding environment during the emptying process. The printing ink has a certain viscosity and dries quickly, which pollutes the environment and increases the cleaning work of the equipment, thereby affecting the ink filling production efficiency.

[0004] Therefore, the prior art has defects and needs to be improved. Utility Model Content

[0029] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figures 1 to 8 As shown, the embodiment of the utility model provides a quantitative filling device for printing ink, including a frame 1, a liquid storage tank 2, a three-way rotary valve 3, a push cylinder 4, a piston cylinder 5, a filling head 6 and a lifting and moving mechanism 7;

[0033] like Figure 6 and Figure 7As shown, the liquid storage tank 2 is arranged on the top of the frame 1, and the ink liquid to be filled is stored in the liquid storage tank 2. The three-way rotary valve 3 includes a valve seat 31 and a valve core 32. The valve core 32 is arranged in the valve seat 31. The valve core 32 is provided with a first channel 321, a second channel 322 and a third channel 323 that are interconnected. A rotating shaft 33 is provided at the end of the valve core 32. The movable end of the pushing cylinder 4 is connected to the rotating shaft 33 through a swing arm 41. The pushing cylinder 4 is used to drive the valve core 32 to rotate. A first interface 311, a second interface 312 and a third interface 313 are provided on the valve seat 31. The first interface 311 is connected to the liquid storage tank 2 through a first hose 81, the second interface 312 is connected to the filling head 6 through a second hose 82, and the movable end of the piston cylinder 5 is connected to the third interface 313. The pushing cylinder 4 can switch the on-off state of the three-way rotary valve 3. Specifically, when it is necessary to fill ink liquid, the pushing cylinder 4 can push the valve core 32 to rotate in the valve seat 31, so that the first channel 321 of the valve core 32 is aligned with the first interface 311, the second channel 322 is aligned with the second interface 312, and the third channel 323 is aligned with the third interface 313. At this time, the three-way rotary valve 3 is in the on state, and the ink liquid in the liquid storage tank 2 can flow into the valve seat 31 under the action of gravity. Then the piston cylinder 5 can be pushed upward to provide pneumatic pressure to the valve seat 31, so as to cause the ink liquid in the valve seat 31 to be poured into the filling head 6 for filling; when it is necessary to close the on state of the three-way rotary valve 3, it is only necessary to push the valve core 32 in the opposite direction by the pushing cylinder 4. At this time, the wall surface of the valve core 32 abuts against the first interface 311 to block the inflow of ink liquid.

[0034] like Figure 4 and Figure 5 As shown, the lifting and moving mechanism 7 includes a lifting cylinder 71, a lifting frame 72, a transverse slide bar 73 and a slider 74. The movable end of the lifting cylinder 71 is arranged upward and connected to the lifting frame 72. The lifting cylinder 71 is used to drive the lifting frame 72 to lift and move. The transverse slide bar 73 is arranged on the lifting frame 72. One side wall of the slider 74 is connected to the filling head 6. The other side wall of the slider 74 is provided with a slide groove 740 adapted to be clamped with the transverse slide bar 73. The filling head 6 can slide along the length direction of the transverse slide bar 73 through the slider 74. When the filling head 6 is filling the container with ink liquid, the lifting cylinder 71 can push the lifting frame 72 to descend so that the bottom of the filling head 6 can penetrate into the container for filling, thereby avoiding contamination caused by splashing of ink liquid; when it is necessary to replace containers of different sizes and shapes for filling, the user can move the filling head 6 to different positions by pushing and pulling the slider 74 to adjust the distance between two adjacent filling heads 6 to meet the needs of ink filling containers of different sizes or shapes.

[0035] like Figure 4 and Figure 5 As shown, further, it also includes a waste liquid collection component 9, which is arranged below the filling head 6 to collect the waste ink liquid in the filling head 6; the waste liquid collection component 9 includes a telescopic cylinder 91 and a waste liquid tank 92, the telescopic cylinder 91 is arranged at the side end below the filling head 6, and the movable end of the telescopic cylinder 91 is connected to the waste liquid tank 92, and the telescopic cylinder 91 is used to push the waste liquid tank 92 to move to the bottom of the filling head 6 or move away from the bottom of the filling head 6. Since the waste ink liquid of the last filling will remain inside the filling head 6, when it is necessary to fill a new batch of containers with ink, the waste ink liquid inside the filling head 6 needs to be discharged. At this time, the telescopic cylinder 91 can push the waste liquid tank 92 to move to the bottom of the filling head 6 to receive the waste ink liquid inside the filling head 6, so as to avoid the waste ink liquid in the filling head 6 from being poured into the new container, thereby affecting the production quality of the product.

[0036] like Figure 4 and Figure 5 As shown, further, the lifting and moving mechanism 7 also includes a bottom plate 75, a vertical slide bar 76 and a linear bearing 77. The bottom plate 75 is arranged below the lifting frame 72. The bottom plate 75 and the lifting frame 72 are connected by a plurality of vertical slide bars 76. The linear bearing 77 is arranged on the lifting frame 72, and the vertical slide bar 76 is passed through the linear bearing 77. The lifting frame 72 can slide along the vertical slide bar 76. The arrangement of the vertical slide bar 76 and the linear bearing 77 can improve the movement stability of the lifting frame 72.

[0037] like Figure 6 As shown, further, the piston cylinder 5 includes a cylinder body 51, a piston 52 and a cylinder barrel 53. The top of the cylinder barrel 53 is connected to the third interface 313, the piston 52 is located in the cylinder barrel 53, the movable end of the cylinder body 51 is connected to the bottom of the piston 52 through a pull rod, and the cylinder body 51 is used to drive the piston 52 to reciprocate along the inner wall of the cylinder barrel 53. When the external air source pressure is applied to the cylinder body 51, the air pressure can push the piston 52 to slide toward the valve seat 31, so as to cause the ink liquid in the valve seat 31 to flow into the filling head 6 through the second hose 82.

[0038] like Figures 1 to 3 As shown, further, a liquid supply pipe 21 is provided in the liquid storage tank 2, and the liquid supply pipe 21 is used to transport ink liquid to the liquid storage tank 2. A plurality of liquid outlet branches 211 are arranged at intervals on the liquid supply pipe 21. The arrangement of the liquid outlet branches 211 can improve the flow uniformity of the ink liquid.

[0039] Furthermore, the number of the filling heads 6, the three-way rotary valve 3, the push cylinder 4 and the piston cylinder 5 are eight. Such an arrangement enables the device to perform filling processing of multiple ink liquids at the same time, thereby improving production efficiency.

[0040] like Figure 5 As shown, further, the length of the waste liquid groove 92 is greater than the length of the transverse sliding rod 73. Such an arrangement can prevent the waste ink from dripping from both sides of the waste liquid groove 92.

[0041] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
