Description

Technical Field

[0001] The present invention relates to the technical field of ink production, and particularly to a feeding device for digital printing ink production. Background Art

[0002] The production process and preparation technology of digital printing ink integrate technologies in multiple fields such as fine chemical engineering, material science, and fluid mechanics. The core lies in achieving high stability, color accuracy, and smooth inkjet printing of the ink. Among them, feeding devices are used in both the raw material pretreatment stage and the dispersion and grinding stage. In the raw material pretreatment stage, the feeding device mainly feeds materials into the premixing tank. In the dispersion and grinding stage, the feeding device mainly replenishes materials into the grinding machine. In both stages, the materials fed by the feeding device include liquids and solid powders.

[0003] Most inks are made using carbon black, also known as lampblack or soot. Some also use acid black dyes, lampblack (i.e., soot), and water-soluble oxidized aniline melanin as colorants. Carbon black is the general term for carbonaceous substances obtained from various raw materials. There are many types, and the main ones used as ink raw materials are carbon black and lampblack, which are light powdery solids obtained from the black smoke of burning pinewood, tung wood, asphalt, or kerosene. The feeding device is used to put these light powdery solids into the mixing tank for mixing with various other raw materials.

[0004] Based on the above technical features, the problems that occur are as follows: In the prior art, during feeding, due to the scattering characteristics of raw material particles and their own gravity, they often naturally accumulate in a conical shape. During the mixing process, it is necessary to stir for a long time to disperse the raw materials, resulting in low mixing efficiency and easy uneven mixing of the materials.

[0005] Therefore, it is very necessary to solve the above problems through a feeding device for digital printing ink production. Summary of the Invention

[0048] The sliding sleeve 23 penetrates upward through the feeding box 15 and is in limit sliding fit with the top box body of the feeding box 15 in the horizontal direction.

A driving assembly for driving the push block 24 to reciprocate along the radial direction of the rotating tube 10 is arranged between the base 1 and the feeding box 15.

[0050] Specifically, the driving assembly includes a vertical shaft 5. The vertical shaft 5 coaxially penetrates through the rotating tube 10. The bottom end of the vertical shaft 5 penetrates through the base 1, and a cam 9 is fixedly sleeved at the top end of the vertical shaft 5.

[0052] Two electric push rods 7 are fixedly installed on the base 1. The two electric push rods 7 are evenly distributed along the circumferential direction of the vertical shaft 5. The telescopic shafts of the two electric push rods 7 are vertically upward and are fixedly connected to drive the transmission ring 6. In this embodiment, the transmission ring 6 extends two flat plates outward, and the two flat plates correspond to the two electric push rods 7 one by one. The telescopic shaft of each electric push rod 7 is fixedly connected to the corresponding flat plate.

[0053] A spiral groove 8 is opened on the vertical shaft 5 along the circumferential direction. A convex block is fixedly arranged on the base 1. The convex block is located in the spiral groove 8 and is in limit sliding fit with the spiral groove 8.

[0054] The bottom and top of the feeding box 15 are both provided with box openings. Two mounting grooves are horizontally opened at the bottom end of the side of the feeding box 15, and the two mounting grooves penetrate through the feeding box 15 along the sliding direction of the pushing block 24. The vertical shaft 5 is located between the two mounting grooves, and the two mounting grooves are symmetrical with respect to the vertical shaft 5.

[0055] The opposite ends of the two mounting grooves communicate with the feeding box 15, and the opposite ends of the two mounting grooves are notch openings. A slide plate 26 is installed in each mounting groove in a limited sliding manner, and the two slide plates 26 both penetrate through the corresponding mounting grooves.

[0056] A plurality of horizontal rotating shafts 31 are horizontally arranged between the two slide plates 26. The plurality of rotating shafts 31 are located on the same horizontal plane and are parallel to each other. The plurality of rotating shafts 31 are not coaxial and are evenly distributed at equal intervals along the radial direction of the rotating pipe 10. Each rotating shaft 31 penetrates through the two slide plates 26 and is rotatably connected to the two slide plates 26.

[0057] A dispersion plate 32 is fixedly arranged on each rotating shaft 31. Each dispersion plate 32 is parallel to the corresponding rotating shaft 31 and is arranged along the radial direction of the rotating shaft 31. The plurality of dispersion plates 32 are parallel to each other.

[0058] A linkage mechanism for driving all the rotating shafts 31 to rotate synchronously is arranged between the feeding box 15 and the mixing tank 3.

[0059] Specifically, the linkage mechanism includes a gear 33 and a rack 36. The corresponding end of each rotating shaft 31 on the same side penetrates through the feeding box 15 and is coaxially and fixedly connected to a gear 33.

[0060] The rack 36 is horizontally installed on the feeding box 15 in a limited sliding manner. The specific installation method is that a guide rail 34 is fixedly arranged on the outer wall of the feeding box 15 along the sliding direction of the pushing block 24. A track with a downward-facing notch and a T-shaped vertical cross-section is opened in the guide rail 34 along the sliding direction of the pushing block 24. A matching pull rod 35 is inserted into the track. The rack 36 is fixedly arranged at the bottom of the pull rod 35 along the sliding direction of the pull rod 35. The pull rod 35 and the rack 36 are integrally arranged.

[0062] A horizontal ring plate 41 is fixedly installed at the top tank opening of the mixing tank 3, and the rotating pipe 10 coaxially penetrates through the ring plate 41.

[0064] To ensure force balance, in this embodiment, two linkage mechanisms are provided, and the two linkage mechanisms are symmetrically arranged relative to the feeding box 15. The cross bar 37 is fixed between the two pull rods 35.

[0065] To ensure the stability of the transmission shaft 40 sliding along the annular groove 42, a plurality of third springs 38 are fixedly arranged between the cross bar 37 and the feeding box 15 along the moving direction of the cross bar 37. The plurality of third springs 38 are parallel to each other and evenly spaced along the horizontal plane.

[0066] Two vertical and symmetrically arranged spring telescopic rods are fixedly installed on the top of each slide plate 26, and a clearance groove 27 for the spring telescopic rods to slide and give way is provided on the box body of the feeding box 15. The top groove wall of the clearance groove 27 is V-shaped, and the telescopic end of each spring telescopic rod slides against the top groove wall of the clearance groove 27.

[0067] Specifically, the spring telescopic rod includes a vertical fixed rod 28 and a vertical movable rod 29, wherein the fixed rod 28 is fixed to the top of the slide plate 26. A slot is provided in the fixed rod 28 in the vertical direction, and the movable rod 29 is inserted into the slot and is limitedly slidably matched with the fixed rod 28. A second spring 30 is vertically arranged in the slot, wherein the top end of the second spring 30 is fixedly connected to the movable rod 29, and the bottom end of the second spring 30 is fixedly connected to the fixed rod 28.

[0068] Working principle: When using the feeding device to produce digital printing ink, first add an appropriate amount of raw materials for the digital printing ink to the cavity above the quantitative partition 17 of the feeding box 15, and then flatten the raw materials.

[0069] Next, the hydraulic rod 16 is started, and the telescopic end of the hydraulic rod 16 is retracted upward and drives the quantitative partition 17 to slide upward, and the quantitative partition 17 pushes the raw material upward. When the plane of the top of the raw material contacts the top inner wall of the feeding box 15, the hydraulic rod 16 is turned off. At this time, the cavity of the feeding box 15 located above the quantitative partition 17 is the amount of raw material added, and then it is only necessary to fill the cavity with raw materials, and it only needs to be measured once in the city, and no repeated weighing and measurement is required.

[0070] Afterwards, the two electric push rods 7 are started simultaneously.

[0071] After the electric push rod 7 is started, the telescopic shaft of the electric push rod 7 drives the transmission ring 6 to move downward, and the transmission ring 6 drives the vertical shaft 5 to move downward. When the vertical shaft 5 moves downward, the protrusion pushes the vertical shaft 5 to rotate through the spiral groove 8. At the same time, the vertical shaft 5 drives the cam 9 to move downward and rotate. When the cam 9 moves downward, the protrusion of the cam 9 will contact the push block 24.

[0072] After the protrusion of the cam 9 contacts the push block 24, it will push the push block 24 away from the vertical shaft 5. At this time, the push block 24 pushes the sliding sleeve 23 to compress the first spring 25. At the same time, the sliding sleeve 23 pushes the push rod 22 away from the vertical shaft 5, the push rod 22 drives all the connecting blocks 20 to slide away from the vertical shaft 5, and all the connecting blocks 20 drive the corresponding baffle plates 19 to open the corresponding material leakage perforations 18. After the material leakage perforations 18 are opened, the raw materials fall into the cavity of the feeding box 15 located below the quantitative partition plate 17 through the material leakage perforations 18.

[0073] To prevent the connecting blocks 20 from being mixed with raw materials, the connecting blocks 20 can be triangular prism blocks with an isosceles triangle cross-section. Among them, the intersection of the two waists of the isosceles triangle is located at the end of the connecting block 20 that radially moves away from the vertical shaft 5 along the vertical shaft 5. And, to prevent raw materials from remaining on the top surface of the baffle plate 19, the top of the baffle plate 19 is set as an inclined surface, that is, the edge of the top end face of the baffle plate 19 close to the vertical shaft 5 is lower than the edge far from the vertical shaft 5.

[0074] When all the raw materials flow from the cavity of the feeding box 15 located above the quantitative partition plate 17 into the cavity located below the quantitative partition plate 17, the telescopic shaft of the electric push rod 7 pushes the transmission ring 6 to move upward. The transmission ring 6 drives the vertical shaft 5 to move upward. When the vertical shaft 5 moves upward, the convex block pushes the vertical shaft 5 to reverse through the spiral groove 8. At the same time, the vertical shaft 5 drives the cam 9 to move upward and reverse. When the cam 9 moves upward, the protrusion of the cam 9 will be separated from the contact with the push block 24.

[0075] After the protrusion of the cam 9 is separated from the push block 24, under the elastic force of the first spring 25, the sliding sleeve 23 slides close to the vertical shaft 5 and pushes the push rod 22 close to the vertical shaft 5. The push rod 22 drives all the connecting blocks 20 to slide close to the vertical shaft 5, and all the connecting blocks 20 drive the corresponding baffle plates 19 to close the corresponding material leakage perforations 18.

[0076] After that, the motor 12 is started. The output shaft of the motor 12 drives the second bevel gear 13 to rotate. The second bevel gear 13 pushes the first bevel gear 11 to rotate. The first bevel gear 11 drives the rotating tube 10 to rotate. The rotating tube 10 drives the mounting seat to revolve around the vertical shaft 5. The mounting seat drives the feeding box 15 to revolve around the vertical shaft 5. The feeding box 15 drives the guide rail 34 to revolve around the vertical shaft 5. The guide rail 34 drives the pull rod 35 to revolve around the vertical shaft 5. The pull rod 35 drives the cross bar 37 to revolve around the vertical shaft 5. The cross bar 37 drives the support rod 39 to revolve around the vertical shaft 5. The support rod 39 drives the transmission shaft 40 to revolve around the vertical shaft 5. During this process, the transmission shaft 40 slides along the ring groove 42, and the ring plate 41 pushes the transmission shaft 40 to slide radially back and forth close to and away from the rotating tube 10.

[0077] When the transmission shaft 40 slides along the annular groove 42, the pull rod 35 is driven to reciprocate along the guide rail 34 through the support rod 39 and the cross bar 37. The pull rod 35 drives the rack 36 to reciprocate, and the rack 36 pushes all the gears 33 to rotate forward and backward synchronously. All the gears 33 drive the corresponding rotating shafts 31 to rotate forward and backward synchronously, and all the rotating shafts 31 drive the corresponding dispersion plates 32 to swing reciprocally.

[0078] In this embodiment, the end of the dispersion plate 32 far from the corresponding rotating shaft 31 is located below the rotating shaft 31. And in the initial state, the transmission shaft 40 is located at the trough of the annular groove 42; the dispersion plate 32 farthest from the rotating tube 10 contacts the bottom of the box body of the feeding box 15 far from the rotating tube 10, and the top of the dispersion plate 32 closest to the rotating tube 10 contacts the inner wall of the box body of the feeding box 15 close to the rotating tube 10. At this time, the bottom ends of all the dispersion plates 32 are inclined away from the rotating tube 10, and at the same time, two adjacent dispersion plates 32 are in contact with each other. As Figure 11 shown.

[0079] When all the rotating shafts 31 drive the corresponding dispersion plates 32 to swing reciprocally, all the dispersion plates 32 first rotate close to the rotating tube 10. During this process, the dispersion plate 32 farthest from the rotating tube 10 separates from the bottom of the box body of the feeding box 15 far from the rotating tube 10, the top of the dispersion plate 32 closest to the rotating tube 10 separates from the inner wall of the box body of the feeding box 15 close to the rotating tube 10, and the gap between two adjacent dispersion plates 32 gradually becomes larger. When all the dispersion plates 32 rotate to the vertical state, the gap between two adjacent dispersion plates 32 is the largest. As Figure 12 shown.

[0080] When gaps appear between two adjacent dispersion plates 32, the raw materials are diverted into the mixing tank 3 from multiple gaps. At the same time, along with the rotation of the feeding box 15 around the vertical shaft 5, the raw materials are tiled circumferentially and radially along the vertical shaft 5 into the mixing tank 3.

[0081] When all the dispersion plates 32 rotate to the vertical state for the first time, all the dispersion plates 32 continue to rotate close to the rotating tube 10. At this time, the gap between two adjacent dispersion plates 32 gradually becomes smaller. Finally, the dispersion plate 32 closest to the rotating tube 10 contacts the bottom of the box body of the feeding box 15 close to the rotating tube 10.

[0082] After the dispersion plate 32 closest to the rotating tube 10 contacts the bottom of the box body of the feeding box 15 close to the rotating tube 10, the dispersion plate 32 pushes the corresponding rotating shaft 31 to move away from the rotating tube 10 under the action of the reaction force, and at the same time, relative sliding occurs between the dispersion plate 32 and the bottom of the box body of the feeding box 15 close to the rotating tube 10.

[0083] When the dispersion plate 32 closest to the rotating tube 10 pushes the corresponding rotating shaft 31 to move away from the rotating tube 10, the moving speed of all the gears 33 is less than that of the rack 36. At the same time, the rotating shaft 31 where the dispersion plate 32 closest to the rotating tube 10 is located pushes the two sliding plates 26 to slide synchronously. The two sliding plates 26 drive the corresponding spring telescopic rods to slide along the corresponding relief grooves 27, and the spring telescopic rods slide from one end of the relief groove 27 close to the rotating tube 10 to the end far from the rotating tube 10. During this process, the movable rod 29 of the spring telescopic rod first slides and abuts against the surface of the top groove wall of the relief groove 27 close to the rotating tube 10; then, after the movable rod 29 passes the lowest point of the top groove wall of the relief groove 27, it slides and abuts against the surface of the top groove wall of the relief groove 27 far from the rotating tube 10; at this time, under the elastic force of the second spring 30, the spring telescopic rod drives the connected sliding plate 26 to quickly move away from the rotating tube 10; at the same time, the two sliding plates 26 drive all the rotating shafts 31 to quickly move away from the rotating tube 10, and all the rotating shafts 31 drive the corresponding gears 33 and dispersion plates 32 to move synchronously and quickly; the moving speed of all the gears 33 is greater than that of the rack 36, and all the gears 33 reverse and drive the corresponding rotating shafts 31 to reverse. When the spring telescopic rod moves to one end of the relief groove 27 far from the rotating tube 10, all the dispersion plates 32 are in the vertical state for the second time. As Figure 13 shown.

[0084] After that, all the dispersion plates 32 rotate towards the rotating tube 10 again. When the dispersion plate 32 closest to the rotating tube 10 contacts the bottom of the box body of the feeding box 15 close to the rotating tube 10 again, and the top of the dispersion plate 32 farthest from the rotating tube 10 contacts the inner wall of the feeding box 15 far from the rotating tube 10, the transmission shaft 40 is located at the peak of the annular groove 42. As Figure 14 shown.

[0085] Figure 11 and Figure 12 and Figure 13 and Figure 14 are the intermediate state diagrams of the transmission shaft 40 sliding one unit along the annular groove 42 from the trough to the peak. The state of the transmission shaft 40 sliding one unit along the annular groove 42 from the peak to the trough is opposite to the state of sliding one unit from the trough to the peak.
