Description

Technical Field

[0001] This utility model relates to the field of ink production equipment technology, and in particular to an ink grinding machine. Background Technology

[0002] Various related equipment are required in the ink production process. For example, the three-roll mill is a commonly used ink processing equipment. It achieves the grinding effect by pressing the surfaces of three horizontal rollers against each other and rubbing at different speeds.

[0003] Chinese Patent CN110898914A discloses a three-roller ink grinding mill, belonging to the technical field of ink production equipment. It includes a grinding disc, a support column fixedly installed at the bottom of the grinding disc, and a support frame fixedly installed at the upper end of the grinding disc. A support plate is installed inside the support frame, and the support plate includes a first fixed plate, a second fixed plate, and a third fixed plate. An adjustment mechanism is installed inside the second fixed plate, and the adjustment mechanism is connected to both the first and third fixed plates. This invention uses the adjustment mechanism to synchronously adjust the distance between the first and third grinding rollers and the second grinding roller, making the adjustment more precise and the operation more convenient. Furthermore, the first and third grinding rollers can be adjusted independently, and the addition of a feeding hopper ensures more uniform feeding, thereby improving grinding efficiency and making it more practical.

[0004] The above technical solution uses an adjustment mechanism to synchronously adjust the distance between the first and third grinding rollers and the second grinding roller, making the adjustment more precise and the operation more convenient. However, during use, the first and third grinding rollers are adjustable and movable. Since the third grinding roller is located below the feed box, and the positions of the feed box and the lower feed hopper are fixed, after adjusting the position of the third grinding roller, when the ink is fed onto the third grinding roller through the through hole of the feed hopper, a positional shift will occur, resulting in uneven feeding. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide an ink grinding machine that has the advantages of easy disassembly and replacement without affecting the grinding quality.

[0006] To achieve the above and other related objectives, the present invention provides the following technical solution:

[0007] An ink grinding machine includes: a grinding disc with multiple support legs mounted on its bottom; a support frame mounted above the grinding disc; three sets of mounting plates mounted on both sides of the support frame, with a grinding roller rotatably fitted between each set of mounting plates; a feed box mounted on the upper side of the support frame, a feed hopper mounted on the bottom of the feed box and connected thereto, and a receiving box slidably fitted above the grinding disc; and a fixing frame mounted on one side of the support frame, with an adjustment component provided between the fixing frame and the mounting plates.

[0008] To achieve the above technical solution, a set of mounting plates near the feed box is fixedly installed on the support frame, so that the position of the grinding rollers on the mounting plates is always fixed. After adjusting the position between multiple sets of grinding rollers by adjusting the component, the position of the feed box and the feed hopper and the grinding rollers below remain unchanged, reducing the situation of uneven ink feeding after the position of the grinding rollers changes.

[0009] In one embodiment of the present invention, the adjusting assembly includes an adjusting plate that is slidably fitted within a fixed frame. A threaded hole is provided on one side of the adjusting plate, and a threaded adjusting rod is threadedly fitted into the threaded hole. A through groove is provided on one side of the fixed frame that rotatably engages with the threaded adjusting rod.

[0010] To achieve the above technical solution, the threaded adjustment rod and the threaded hole of the adjustment plate are threadedly engaged, so that when the threaded adjustment rod in the through groove is rotated, the adjustment plate can be driven to slide within the fixed frame.

[0011] In one embodiment of this utility model, two sliders are slidably fitted inside the adjusting plate. A fixing block is installed on one side of each set of mounting plates. Multiple connecting brackets are arranged between the sliders and the fixing blocks. Two first connecting posts are installed on one side of the sliders, and two second connecting posts are installed on one side of the fixing blocks. Connecting grooves are opened on both sides of the connecting brackets. The first connecting posts are rotatably fitted in one of the connecting grooves, and the second connecting posts are rotatably fitted in the other connecting groove.

[0012] To achieve the above technical solution, since one set of mounting plates is fixed, the adjusting plate that slides within the fixed frame drives the other two sets of mounting plates to slide on the support frame via the slider and connecting frame, and the distance that the other two sets of mounting plates move is the same as the distance between them and the fixed set of mounting plates.

[0013] In one embodiment of this utility model, a set of mounting plates near the feed box is fixedly mounted on the support frame, and the other two sets of mounting plates are slidably fitted on the support frame. A drive motor is mounted on the other side of the three sets of mounting plates, and the output end of the drive motor is fixedly connected to the rotating shaft of the grinding roller.

[0014] In one embodiment of this utility model, a connecting block is installed on one side of the receiving box, and one side of the connecting block is installed on the outermost mounting plate. A scraper is installed at the inlet of the receiving box and on the surface of the outermost grinding roller. An inclined feeding groove is opened in the feeding hopper, and multiple through holes are opened at the bottom of the feeding groove.

[0015] To achieve the above technical solution, an inclined feeding trough is installed at the bottom of the feeding hopper, so that the ink can be added sequentially from top to bottom along the through hole during feeding, thereby making the feeding more uniform.

[0016] As described above, the ink grinding machine provided by this utility model has the following beneficial effects:

[0017] This utility model provides an ink grinding machine, comprising: a grinding disc with multiple support legs at the bottom; a support frame mounted above the grinding disc; three sets of mounting plates mounted on both sides of the support frame, with a grinding roller rotatably fitted between each set of mounting plates; a feed box mounted on the upper side of the support frame, a feed hopper mounted at the bottom of the feed box and connected thereto, and a receiving box slidably fitted above the grinding disc; a fixed frame mounted on one side of the support frame, with an adjustment assembly between the fixed frame and the mounting plates. By fixing one set of mounting plates near the feed box to the support frame, the position of the grinding roller on this set of mounting plates is always fixed. By rotating the threaded adjustment rod, the adjustment plate is moved to slide within the fixed frame. The sliding fixed frame, through a slider and a connecting frame, moves the other two sets of mounting plates to adjust their positions by the same distance. This ensures that after adjusting the positions of multiple sets of grinding rollers, the positions of the feed box and feed hopper relative to the grinding roller below remain unchanged, reducing uneven ink feeding caused by changes in the position of the grinding rollers.

[0027] Please see Figure 1This utility model provides an ink grinding machine, including a grinding disc 1 with multiple support legs 2 at the bottom; a support frame 3 mounted above the grinding disc 1; three sets of mounting plates 4 mounted on both sides of the support frame 3, with a grinding roller 10 rotatably engaged between each set of mounting plates 4; a feed box 7 mounted on the upper side of the support frame 3; a feed hopper 8 mounted on the bottom of the feed box 7 and connected to it; a receiving box 9 slidably engaged above the grinding disc 1; a fixing frame 5 mounted on one side of the support frame 3; and an adjustment component provided between the fixing frame 5 and the mounting plates 4. 6. One set of mounting plates 4 near the feed box 7 is fixedly mounted on the support frame 3, and the other two sets of mounting plates 4 are slidably fitted on the support frame 3. By fixing one set of mounting plates 4 near the feed box 7 on the support frame 3, the position of the grinding roller 10 on the mounting plate 4 is always fixed. After adjusting the position between multiple sets of grinding rollers 10 by adjusting the component 6, the position of the feed box 7 and the feed hopper 8 and the grinding roller 10 below remain unchanged, reducing the situation of uneven ink feeding after the position of the grinding roller 10 changes.

[0028] Please see Figure 2-3 The adjusting assembly 6 includes an adjusting plate 601 that slides within the fixed frame 5. A threaded hole 602 is provided on one side of the adjusting plate 601, and a threaded adjusting rod 603 is threaded into the threaded hole 602. A through groove 610 is provided on one side of the fixed frame 5 to rotatably engage with the threaded adjusting rod 603. Two sliders 604 slide within the adjusting plate 601.

Connecting brackets 606 have connecting posts on both sides. The first connecting post 607 is rotatably fitted in one of the connecting grooves 609, and the second connecting post 608 is rotatably fitted in the other connecting groove 609. Because the threaded adjusting rod 603 is threadedly fitted with the threaded hole 602 of the adjusting plate 601, rotating the threaded adjusting rod 603 in the through groove 610 can drive the adjusting plate 601 to slide within the fixed frame 5. Since one set of mounting plates 4 is fixed, the adjusting plate 601 sliding within the fixed frame 5 drives the other two sets of mounting plates 4 to slide on the support frame 3 through the slider 604 and the connecting bracket 606. The distance that the other two sets of mounting plates 4 move is the same as the distance between them and the fixed set of mounting plates 4.
