In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0023] like Figure 1-6 As shown, a coating supply device for a printing press comprises a mixing cylinder 1, a partition plate 2 and a feed hole 4, wherein the mixing cylinder 1 is provided with a partition plate 2, and the upper and lower ends of the partition plate 2 are a first storage chamber 3 and a second storage chamber 5, the feed hole 4 is connected to the first storage chamber 3, the mixing cylinder 1 is provided with a discharge hole 6 connected to the second storage chamber 5, the discharge hole 6 is connected to the printing press, a driving device 7 is provided inside the first storage chamber 3, the driving device 7 drives the first plug 9 to control the closing of the feed hole 4, the driving device 7 drives the partition plate 2 to control the connection or isolation between the first storage chamber 3 and the second storage chamber 5, a release device 8 is provided inside the first storage chamber 3 to control the position of the driving device 7, and a stirring device 10 for stirring the material inside the second storage chamber 5 is provided on the partition plate 2.
[0024] The discharge hole 6 inside the second storage chamber 5 replenishes the paint to the printing press. As the paint is used, the paint inside the first storage chamber 3 is continuously replenished to the first storage chamber 3. When the paint inside the first storage chamber 3 passes through the dividing plate 2, it will drive the stirring device 10 to stir the paint inside the first storage chamber 3. As the paint is used, the paint in the first storage chamber 3 gradually decreases. When the paint is less than a certain amount, the releasing device 8 releases the limit on the driving device 7, and then the driving device 7 drives the first plug 9 to no longer block the feed hole 4. The material replenishes the paint to the first storage chamber 3 through the feed hole 4. At the same time, the driving device 7 closes the dividing plate 2 to prevent the first storage chamber 3 from directly entering the second storage chamber 5 and causing uneven mixing of the paint.
[0025] Among them, Figure 1-6 As shown, the partition plate 2 includes a plate body 2-1 and a second discharge hole 2-2. The plate body 2-1 is provided with a second discharge hole 2-2, which connects the first storage chamber 3 and the second storage chamber 5. The stirring device 10 is arranged inside the second discharge hole 2-2.
[0026] Among them, Figure 1-6 As shown, the driving device 7 includes a mounting rod 7-1, a mounting box 7-2, a sliding cavity 7-3, a movable float box 7-4, a bevel limit groove 7-5 and a second plug 7-6. The mounting box 7-2 is arranged inside the first storage cavity 3 through the mounting rod 7-1, the movable float box 7-4 slides inside the mounting box 7-2 through the sliding cavity 7-3, the bevel limit groove 7-5 is arranged on the movable float box 7-4, the release device 8 controls the position of the movable float box 7-4 through the movable float box 7-4, the second plug 7-6 is arranged on the movable float box 7-4, and the first plug 9 is arranged on the movable float box 7-4.
[0027] When the amount of paint inside the first storage chamber 3 is less than a certain amount, the release device 8 will no longer limit the movable float box 7-4 through the inclined limit groove 7-5, and the movable float box 7-4 will move downward inside the installation box 7-2. The movable installation box 7-2 drives the first plug 9 to move and open the feed hole 4. At the same time, the float box 7-4 drives the second plug 7-6 to move the discharge hole 2-2 to prevent the paint inside the two chambers from mixing.
[0028] Among them, Figure 1-6As shown, the release device 8 includes a sleeve 8-1, a float 8-2, a connecting rod 8-3, an extrusion inclined panel 8-4, a fixing tube 8-5, a push bolt 8-6, a push plate 8-7, a spring 8-8, a connecting plate 8-9 and a limiting inclined strip 8-10. The sleeve 8-1 is arranged on the dividing plate 2, the float 8-2 slides inside the sleeve 8-1, the connecting rod 8-3 is arranged on the float 8-2, and the connecting rod 8-3 is provided with an extrusion inclined panel 8-4, which is wide at the top and narrow at the bottom. The fixed cylinder 8-5 is arranged on the installation box 7-2, the pushing bolt 8-6 slides inside the fixed cylinder 8-5, a spring 8-8 is arranged between the pushing bolt 8-6 and the fixed cylinder 8-5, the pushing plate 8-7 is arranged on the pushing bolt 8-6, the extrusion inclined plate 8-4 extrudes and pushes the pushing plate 8-7, the connecting plate 8-9 is arranged on the pushing bolt 8-6, the limiting inclined strip 8-10 is arranged on the connecting plate 8-9, and the limiting inclined strip 8-10 limits the movable float box 7-4 from moving downward through the inclined limiting groove 7-5.
[0029] When the paint is less than a certain amount, the paint gives less buoyancy to the float 8-2, and the float 8-2 will move downward, and the moving float 8-2 drives the extrusion inclined plate 8-4 to move through the connecting rod 8-3, and the moving extrusion inclined plate 8-4 will push the push plate 8-7 to move, and the push plate 8-7 drives the connecting plate 8-9 to move through the push bolt 8-6, and the connecting plate 8-9 drives the limiting inclined strip 8-10 to move and slide from the inside of the inclined limiting groove 7-5 to release the limit of the mobile float box 7-4. Then, as the paint increases, the float 8-2 will move upward to push the extrusion inclined plate 8-4 to reset, and then when the mobile float box 7-4 is subjected to the buoyancy of the paint and moves back to the original position, it is restricted again.
[0030] Among them, Figure 1-6 As shown, the stirring device 10 includes a mounting frame 10-1, a rotating shaft 10-2, a turbine 10-3 and a stirring plate 10-4, the mounting frame 10-1 is arranged inside the discharge hole 2-2, the rotating shaft 10-2 is arranged on the mounting frame 10-1, the turbine 10-3 is arranged on the rotating shaft 10-2 and placed inside the discharge hole 2-2, and the stirring plate 10-4 is arranged on the rotating shaft 10-2.
