Description

Technical Field

[0001] This utility model relates to the field of ink technology, and more specifically, to an ink grinding machine powder feeding device. Background Technology

[0002] Ink is a liquid or viscous substance used for printing, writing, or applying. It is usually composed of pigments, resins, solvents, and additives. It has good adhesion, flowability, covering power, and lightfastness. Ink is widely used in the printing industry, such as paper printing, packaging, signage, and electronic products. Ink processing requires the use of grinding mills, and grinding mills require powder feeding devices.

[0003] The grinding process of inks generates a large amount of dust and solvent volatiles. Existing ink grinding machines cannot quickly process these dust and solvent volatiles. If left uncontrolled, this dust will diffuse through the air, leading to a decline in workshop air quality and even polluting the surrounding environment. Prolonged exposure to dust may harm the health of employees, especially long-term inhalation of fine dust, which may cause respiratory diseases, allergic reactions, and other health problems. Solvent volatiles are the solvent components in the ink that evaporate into the air during the grinding process. These volatile solvents not only increase the concentration of harmful substances in the air but may also pollute the environment around the workshop.

[0004] Therefore, we made improvements and proposed a powder feeding device for ink grinding machines. Utility Model Content

[0005] The purpose of this invention is to address the fact that existing ink grinding machine powder feeding devices cannot quickly process dust and solvent volatiles. If these dust particles are not controlled, they will diffuse through the air, leading to a decline in workshop air quality and even polluting the surrounding environment. Long-term exposure to dust may harm the health of employees, especially long-term inhalation of fine dust, which may cause respiratory diseases, allergic reactions, and other health problems. Solvent volatiles are the solvent components in the ink that evaporate into the air during the grinding process. These volatile solvents not only increase the concentration of harmful substances in the air but may also pollute the surrounding environment of the workshop.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The ink grinding machine powder feeding device is designed to improve the above-mentioned problems.

[0008] The application is as follows:

[0009] Includes: a feeding tank; a feed pipe is provided on the top left side of the feeding tank; three support legs are fixedly installed on the bottom of the feeding tank; a discharge pipe is connected to the bottom of the feeding tank; a connecting shell is fixedly installed on the top of the feeding tank; a support plate is fixedly installed on the right side of the feeding tank; an outer shell is fixedly installed on the right side of the support plate; a fan is connected to the rear side of the outer shell; the fan is fixedly connected to the support plate on the side near the support plate; an installation assembly is fixedly installed on the left side of the outer shell; two support frames are provided on one side of the inner cavity of the outer shell, and the two support frames are connected... Two dustproof nets are movably connected between the two sides of the housing. Limiting blocks are fixedly installed on the top and bottom of the left side of the dustproof nets. A dust suction pipe is connected to the top of the housing, and a dust suction head is connected to the bottom of the dust suction pipe. Connecting plates are fixedly installed on both sides of the dust suction head. The top of the connecting plate is fixedly connected to the inner cavity of the housing. A filter plate is fixedly installed on the top of the inner cavity of the feeding tank. A limiting component is fixedly installed on the front side of the right side of the housing. A collection box is movably connected to the front side of the bottom of the inner cavity of the housing. A limiting plate is fixedly installed on the right side of the collection box.

[0010] The above technical solution achieves rapid processing of dust and solvent volatiles generated during ink feeding and grinding by using a combination of a casing, fan, dustproof net, dust suction pipe, dust suction head, and filter plate. If dust and solvent volatiles generated during ink production are not treated in time, they will seriously affect the air quality in the workshop. Through an effective treatment device, the air can be purified in time, reducing the concentration of harmful substances in the air, making the workshop environment fresher and healthier, thereby improving the work comfort and efficiency of employees.

[0011] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, the mounting assembly includes a protective shell, which is fixedly installed on one side of the outer shell. A first fixing plate is movably connected to the front side of the inner cavity of the protective shell. A first pull plate is fixedly installed on the front side of the first fixing plate. Two first movable rods are fixedly installed on one side of the first fixing plate. A fixing frame is movably connected to the surface of the first movable rod. A second movable rod is movably connected to the other side of the inner cavity of the fixing frame. A connecting block is fixedly installed on one side of the second movable rod. A baffle is fixedly installed on the rear side of the connecting block. Two first insert rods are fixedly installed on opposite sides of the two baffles. Two first springs are fixedly installed on opposite sides of the two baffles.

[0012] To achieve the above technical solution, the dustproof net may become clogged on its surface after prolonged use, requiring disassembly and cleaning. Disassembly involves pulling the first pull plate, which moves the first fixed plate. This movement, in turn, causes the two connecting blocks to move relative to each other via the cooperation of the first movable rod, the fixed frame, and the second movable rod. The moving connecting blocks then move the baffle, which in turn moves the first insert rod. This movement also compresses the first spring, moving the first insert rod out of the limiting block, thus disassembling the limiting block. The dustproof net will disassemble along with the limiting block. Reinstallation is achieved by reversing the process, allowing for quick cleaning of dust from the dustproof net's surface.

[0013] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, sliding blocks are fixedly installed on the top and bottom of the first fixed plate, and a sliding rod is slidably connected to the inner cavity of the sliding block. The side of the sliding rod near the protective shell is fixedly connected to the protective shell.

[0014] To achieve the above technical solution, the sliding block and the sliding rod work together to limit and support the first fixed plate when it is pulled, preventing it from shifting position during the pulling process.

[0015] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, a positioning block is fixedly installed on the rear side of the baffle, and a positioning rod is slidably connected to the inner cavity of the positioning block. The top and bottom of the positioning rod are both fixedly installed in the inner cavity of the protective shell.

[0016] To achieve the above technical solution, the positioning block and positioning rod work together to limit and support the baffle when it moves, preventing it from shifting position during movement.

[0017] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, the limiting component includes a protective shell, the protective shell is fixedly installed on one side of the outer shell, a second spring is fixedly installed at the top of the inner cavity of the protective shell, a second fixing plate is fixedly installed at the bottom of the second spring, a second insert rod is fixedly installed at the bottom of the second fixing plate, a second pull plate is fixedly installed on the right side of the second fixing plate, and one side of the second pull plate extends through to the outside of the protective shell.

[0018] To achieve the above technical solution, when the collection box needs to be removed, the second pull plate is pulled. When the second pull plate is pulled, it drives the second fixing plate and the second insert rod to move. It can also compress the second spring and move the second insert rod out of the limit plate, so that the limit plate can be disassembled. The collection box will be disassembled along with the limit plate, and the dust inside the collection box can be quickly removed. When the collection box needs to be installed, the operation is reversed.

[0019] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, movable blocks are fixedly installed on both the front and rear sides of the second fixed plate, and the movable blocks are slidably connected to the inner cavity of the protective shell.

[0020] To achieve the above technical solution, the movable block can limit the position of the second fixed plate, preventing the second fixed plate from shifting during use.

[0021] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, a fixing ring is sleeved on the bottom of the surface of the connecting shell, and the fixing ring is fixedly connected to the feeding tank on the side near the feeding tank.

[0022] In a preferred embodiment of the ink grinding machine powder feeding device provided by this utility model, two positioning plates are fixedly installed on the top and bottom of the outer shell, and the side of the positioning plate near the support plate is fixedly connected to the support plate.

[0041] Please refer to Figure 1-6The ink grinding mill powder feeding device includes: a feeding tank 1; a feeding pipe 2 is provided on the top left side of the feeding tank 1; three support legs 3 are fixedly installed on the bottom of the feeding tank 1; a discharge pipe 4 is connected to the bottom of the feeding tank 1; a connecting shell 5 is fixedly installed on the top of the feeding tank 1; a support plate 6 is fixedly installed on the right side of the feeding tank 1; a shell 7 is fixedly installed on the right side of the support plate 6; a fan 8 is connected to the rear side of the shell 7; the side of the fan 8 closest to the support plate 6 is fixedly connected to the support plate 6; an installation assembly 9 is fixedly installed on the left side of the shell 7; and two support frames 10 are provided on one side of the inner cavity of the shell 7. Two dustproof nets 11 are movably connected between opposite sides. Limiting blocks 12 are fixedly installed on the top and bottom of the left side of the dustproof nets 11. The top of the outer shell 7 is connected to a suction pipe 13, and the bottom of the suction pipe 13 is connected to a suction head 14. Connecting plates 15 are fixedly installed on both sides of the suction head 14. The top of the connecting plate 15 is fixedly connected to the inner cavity of the connecting shell 5. A filter plate 16 is fixedly installed on the top of the inner cavity of the feeding tank 1. A limiting component 17 is fixedly installed on the front right side of the outer shell 7. A collection box 18 is movably connected to the front bottom of the inner cavity of the outer shell 7. A limiting plate 19 is fixedly installed on the right side of the collection box 18. When it is necessary to quickly process the dust and solvent volatiles generated during ink feeding and grinding, the blower 8 is started. During operation, the blower 8 sucks the dust and solvent volatiles generated during ink feeding into the interior of the housing 7 through the suction pipe 13 and the suction head 14. The dust entering the housing 7 is blocked by the dustproof net 11 and falls into the collection box 18, where it is collected and processed. The solvent volatiles are discharged through the other end of the blower 8 into the corresponding collection equipment. This allows for the rapid processing of dust and solvent volatiles generated during ink feeding and grinding, which can purify the air in a timely manner, reduce the concentration of harmful substances in the air, make the workshop environment fresher and healthier, and thus improve the working comfort and efficiency of employees.

[0042] Please see Figure 3 and Figure 5The mounting assembly 9 includes a protective shell 901, which is fixedly mounted on one side of the outer shell 7. A first fixing plate 902 is movably connected to the front side of the inner cavity of the protective shell 901. A first pull plate 903 is fixedly mounted on the front side of the first fixing plate 902. Two first movable rods 904 are fixedly mounted on one side of the first fixing plate 902. A fixing frame 905 is movably connected to the surface of the first movable rods 904. A second movable rod 906 is movably connected to the other side of the inner cavity of the fixing frame 905. A connecting block 907 is fixedly mounted on one side of the second movable rod 906. A baffle 908 is fixedly mounted on the rear side of the connecting block 907. Two first insert rods 909 are fixedly mounted on opposite sides of the two baffles 908. Two first springs 910 are fixedly mounted on opposite sides of the two baffles 908. The dustproof net 11 may become clogged after prolonged use, so it needs to be disassembled and cleaned. When disassembling, pull the first pull plate 903. When the first pull plate 903 is pulled, it drives the first fixed plate 902 to move. When the first fixed plate 902 moves, it drives the two connecting blocks 907 to move relative to each other through the cooperation of the first movable rod 904, the fixed frame 905 and the second movable rod 906. When the connecting blocks 907 move, they drive the baffle 908 to move. When the baffle 908 moves, it drives the first insertion rod 909 to move. When the baffle 908 moves, it also compresses the first spring 910, moving the first insertion rod 909 out of the interior of the limiting block 12, thereby disassembling the limiting block 12. The dustproof net 11 will be disassembled along with the limiting block 12. When it is necessary to install the dustproof net 11, simply reverse the operation, so that the dust on the surface of the dustproof net 11 can be cleaned quickly. Sliding blocks 911 are fixedly installed on both the top and bottom of the first fixed plate 902. A sliding rod 912 is slidably connected to the inner cavity of the sliding block 911, and the side of the sliding rod 912 closest to the protective shell 901 is fixedly connected to the protective shell 901. Through the cooperation of the sliding block 911 and the sliding rod 912, the first fixed plate 902 can be limited and supported when pulled, preventing it from shifting position during pulling. A positioning block 913 is fixedly installed on the rear side of the baffle 908. A positioning rod 914 is slidably connected to the inner cavity of the positioning block 913, and the top and bottom of the positioning rod 914 are fixedly installed in the inner cavity of the protective shell 901. Through the cooperation of the positioning block 913 and the positioning rod 914, the baffle 908 can be limited and supported when moving, preventing it from shifting position during movement.

[0043] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6The limiting component 17 includes a protective shell 1701, which is fixedly installed on one side of the outer shell 7. A second spring 1702 is fixedly installed on the top of the inner cavity of the protective shell 1701. A second fixing plate 1703 is fixedly installed on the bottom of the second spring 1702. A second insert rod 1704 is fixedly installed on the bottom of the second fixing plate 1703. A second pull plate 1705 is fixedly installed on the right side of the second fixing plate 1703. One side of the second pull plate 1705 extends through to the outside of the protective shell 1701. When the collection box 18 needs to be removed, the second pull plate 1705 is pulled. Pulling the second pull plate 1705 moves the second fixing plate 1703 and the second insertion rod 1704, and also compresses the second spring 1702, moving the second insertion rod 1704 out of the limiting plate 19. This allows the limiting plate 19 to be disassembled, and the collection box 18 will disassemble along with the limiting plate 19, allowing for quick removal of dust from inside the collection box 18. Reinstallation of the collection box 18 is achieved by reversing the operation. Movable blocks 1706 are fixedly installed on both the front and rear sides of the second fixing plate 1703, and these movable blocks 1706 are slidably connected to the inner cavity of the protective shell 1701. The movable blocks 1706 limit the position of the second fixing plate 1703, preventing it from shifting during use.

[0044] Specifically, during use, when it is necessary to quickly process the dust and solvent volatiles generated during ink feeding and grinding, the blower 8 is started. The blower 8, through the suction pipe 13 and suction head 14, draws the dust and solvent volatiles generated during ink feeding into the interior of the outer casing 7. The dust entering the outer casing 7 is blocked by the dustproof net 11 and falls into the collection box 18, where it is collected. The solvent volatiles are discharged through the other end of the blower 8 into the corresponding collection device. This quickly processes the dust and solvent volatiles generated during ink feeding and grinding, purifying the air and reducing the concentration of harmful substances, making the workshop environment fresher and healthier, thereby improving employee comfort and efficiency. The dustproof net 11 may become clogged over time, so it needs to be disassembled and cleaned. Disassembly involves pulling the first pull plate 903, which moves the first fixed plate 902. The movement of the first fixed plate 902 is facilitated by the first movable rod 904, the fixed frame 905, and the second movable rod 906. The cooperation of 06 drives the two connecting blocks 907 to move relative to each other. When the connecting block 907 moves, it drives the baffle 908 to move. When the baffle 908 moves, it drives the first insert rod 909 to move. When the baffle 908 moves, it also compresses the first spring 910, moving the first insert rod 909 out of the interior of the limiting block 12, thereby disassembling the limiting block 12. The dustproof net 11 will be disassembled along with the limiting block 12. When it is necessary to install the dustproof net 11, the operation is reversed. This allows for quick cleaning of dust on the surface of the dustproof net 11. To remove the collection box 18, pull the second pull plate 1705. When the second pull plate 1705 is pulled, it moves the second fixing plate 1703 and the second insertion rod 1704. It can also compress the second spring 1702, moving the second insertion rod 1704 out of the interior of the limiting plate 19. This allows the limiting plate 19 to be disassembled, and the collection box 18 will be disassembled along with the limiting plate 19. The dust inside the collection box 18 can be quickly removed. When it is necessary to install the collection box 18, simply reverse the operation.
