[0001] This utility model belongs to the field of ink production technology, specifically relating to a quantitative feeding device for ink production. Background Technology

[0002] The general production process of the ink project is as follows: **Formulation:** Pigments, resins, solvents, and additives are weighed and mixed according to the formula. **Pre-dispersion:** The formulation is stirred in a mixer to wet and initially disperse the pigments. **Grinding:** The pre-dispersed materials are ground at high speed in equipment such as a three-roll mill, ball mill, or sand mill to achieve the required fineness and color concentration. **Filtration:** The ground ink is filtered to remove impurities and particulate matter, ensuring the purity and quality stability of the ink. **Packaging:** The filtered ink is piped to packaging equipment, where automated operation fills the ink into packaging containers.

[0003] Domestic utility model patent application number 202321497565.6 discloses a quantitative feeding mechanism for ink production, including an injection cylinder, a feeding hopper on one side of the injection cylinder, a feed pipe extending into the injection cylinder fixedly installed at the bottom of the feeding hopper, a first solenoid valve fixedly installed on the feed pipe, a stirring mechanism inside the feeding hopper, an electric heating plate fixedly installed on the outer wall of the feeding hopper, a discharge pipe extending into the ink preparation machine fixedly installed at the bottom of the injection cylinder, a second solenoid valve fixedly installed on the discharge pipe, a cylinder fixedly installed at the top of the injection cylinder, a piston rod extending into the injection cylinder at the output end of the cylinder, and a piston plate movably engaged inside the injection cylinder fixedly connected to the bottom end of the piston rod. This utility model relates to the field of ink production technology. This quantitative feeding mechanism for ink production can accurately control the feeding flow rate, make the feeding amount more accurate, and is convenient and safe to operate. The aforementioned utility model uses a piston rod to push the material for feeding. While this method ensures the accuracy of feeding, it makes it difficult to control the air inside the feeding chamber during actual operation. When adding or changing the solvent to the feeding container, the constant air pressure can hinder the feeding process. Furthermore, when the piston rod moves upward, it can easily draw out the raw material inside the mixing container or cause the material that has not completely flowed into the mixing container to flow back, thus affecting the use of the feeding equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a quantitative feeding device for ink production, including a base frame, a mixing tank and a control box fixedly installed on the base frame, a welding frame plate welded to the top of the control box and the base frame, a drive motor fixedly installed on the top of the welding frame plate, a feeding tank fixedly installed on the top of the mixing tank, a lead screw connected to the output end of the drive motor, and a lifting frame threaded through the lead screw. A fixing rod is fixedly installed at the bottom of the lifting frame at the top position of the feeding tank, and a piston block is connected to the bottom of the fixing rod. An inner tank is installed inside the feeding tank, and both the feeding tank and the inner tank have openings at their tops. A main shaft motor is fixedly installed at the bottom of the welding frame plate, and a delivery pump is fixedly installed on the base frame at the bottom position of the mixing tank.

[0005] The drive motor drives the lead screw to rotate, causing the lifting frame to move the piston block at the bottom of the fixed rod up and down, squeezing the solvent raw material inside the feeding tank and introducing it into the mixing tank.

[0006] As a further preferred technical solution of this utility model; a pad is fixedly installed at the bottom of the drive motor, a protective frame is fixedly installed at the top of the pad, a positioning frame is fixedly installed at the top of the protective frame, and the lead screw is installed in the positioning frame.

[0007] By starting the drive motor, the lead screw rotates, causing the lifting frame, whose threads pass through the lead screw, to move up and down. This, in turn, moves the piston block at the other end of the lifting frame up and down. The rotation of the lead screw increases the accuracy of the piston block's downward movement.

[0008] As a further preferred technical solution of this utility model; both the feeding tank and the inner tank are transparent and have scales on their surfaces. The feeding tank is fixedly installed on both sides of the mixing tank and the top of the welding frame plate respectively through support frames. An exhaust layer is installed on the inner wall of the inner tank, and the exhaust layer includes multiple sets of air holes opened on the inner tank. A material injection pipe is installed through the feeding tank on one side of the inner tank at the bottom position of the exhaust layer.

[0009] When injecting a measured amount of solvent into the inner tank, the piston block is moved upwards to the top of the venting layer to avoid clogging the vents, ensuring airflow inside the inner tank and maintaining pressure consistency between the inside and outside. Then, the inner tank is filled through the injection pipe. The readings on the outer surface of the feeding tank and the inner tank are observed. After the required amount of solvent is introduced, the piston block is moved to fill the mixing tank. The vent design balances the internal and external pressures of the inner tank when it is empty, preventing pressure buildup from affecting the inner tank itself and the valve at the bottom outlet when the inner tank is completely sealed. Excessive pressure buildup can cause the piston block to move upwards, affecting the operation of the piston block lifting mechanism or the valve at the bottom of the inner tank. Damage to the valve can also lead to errors in subsequent filling.

[0010] As a further preferred technical solution of this utility model, a guide pipe is installed at the bottom of the inner tank, connecting the feeding tank and the mixing tank, and a diaphragm valve is installed on the guide pipe.

[0011] As the piston moves downwards, the inner tank becomes completely sealed when it reaches the bottom of the exhaust layer. This allows the solvent material inside the inner tank to be fed into the mixing tank through the feed pipe. The diaphragm valve effectively prevents backflow of solvent inside the feed pipe due to suction generated inside the inner tank caused by the piston moving upwards. This ensures the accuracy of quantitative feeding into the mixing tank.

[0012] As a further preferred technical solution of this utility model; the mixing tank is fixedly installed to the base frame through two sets of mounting seats, end caps are installed at both ends of the mixing tank, a stirring paddle is installed inside the mixing tank, and the output end of the main shaft motor passes through the mixing tank and is connected to the stirring paddle. Bearing seats are installed at the other end of the stirring paddle and the lead screw.

[0013] The main shaft motor is connected to the agitator, which drives the agitator to rotate, thereby achieving the mixing effect of the raw materials inside the mixing tank.

[0014] As a further preferred technical solution of this utility model; a support base is installed at the bottom of the base frame, and an installation groove is opened on the base frame. The conveying pump is fixedly installed on the installation groove. One end of the conveying pump is connected to the bottom of the mixing tank through a discharge pipe. Solenoid valves are installed on both the discharge pipe and the injection pipe.

[0015] The ink raw materials, after being mixed inside the mixing tank, are transported by a transfer pump and output to the container for the next step. Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] Material is injected into the mixing tank by moving the piston block. The vent design balances the internal and external air pressures of the inner tank when it is empty, preventing pressure buildup from affecting the inner tank and its bottom discharge valve when the inner tank is completely sealed. Excessive pressure could cause the piston block to move upwards, affecting the operation of the piston block lifting mechanism or the bottom valve of the inner tank. Damage to the valve could also lead to errors in subsequent material feeding.

[0018] As the piston moves downwards, the inner tank becomes completely sealed when it reaches the bottom of the exhaust layer. This allows the solvent material inside the inner tank to be fed into the mixing tank through the feed pipe. The diaphragm valve effectively prevents backflow of solvent inside the feed pipe due to suction generated inside the inner tank caused by the piston moving upwards. This ensures the accuracy of quantitative feeding into the mixing tank. Attached Figure Description

[0024] This specific embodiment is a quantitative feeding device for ink production.

[0025] The aforementioned utility model uses a piston rod to push the material for feeding. While this method ensures the accuracy of feeding, it makes it difficult to control the air inside the feeding chamber during actual operation. When adding or changing the solvent to the feeding container, the constant air pressure can hinder the feeding process. Furthermore, when the piston rod moves upward, it can easily draw out the raw material inside the mixing container or cause the material that has not completely flowed into the mixing container to flow back, thus affecting the use of the feeding equipment.

[0026] Its structural diagram is as follows Figures 1-4 As shown. A quantitative feeding device for ink production includes a base frame 1, a mixing tank 3 and a control box 4 fixedly mounted on the base frame 1, a welded frame plate 13 welded to the top of the control box 4 and the base frame 1, a drive motor 6 fixedly mounted on the top of the welded frame plate 13, a feeding tank 7 fixedly mounted on the top of the mixing tank 3, a lead screw 61 connected to the output end of the drive motor 6, and a lifting frame 62 threaded through the lead screw 61. A fixing rod 74 is fixedly mounted at the bottom of the lifting frame 62 at the top of the feeding tank 7, and a piston block 75 is connected to the bottom of the fixing rod 74. An inner tank 73 is installed inside the feeding tank 7, and both the feeding tank 7 and the inner tank 73 have openings 72 at their tops. A pad 14 is fixedly mounted at the bottom of the drive motor 6, a protective frame 15 is fixedly mounted on the top of the pad 14, a positioning frame 16 is fixedly mounted on the top of the protective frame 15, and the lead screw 61 is installed inside the positioning frame 16. By starting the drive motor 6, the lead screw 61 rotates, causing the lifting frame 62, whose threads pass through the lead screw 61, to move up and down. This, in turn, causes the piston block 75 at the other end of the lifting frame 62 to move up and down. The rotation of the lead screw 61 increases the accuracy of the downward movement of the piston block 75.

[0027] Both the feeding tank 7 and the inner tank 73 are transparent and have graduations on their surfaces. The feeding tank 7 is fixedly mounted to the top of the mixing tank 3 and the welding frame plate 13 via support brackets 71 on both sides. An venting layer 79 is installed on the inner wall of the inner tank 73, and the venting layer 79 includes multiple sets of vents 791 formed on the inner tank 73. A filling pipe 78 is installed through the feeding tank 7 on one side of the inner tank 73, at the bottom of the venting layer 79. When injecting a measured amount of solvent into the inner tank 73, the piston block 75 is moved upwards to the top of the venting layer 79 to avoid clogging the vents 791, ensuring airflow inside the inner tank 73 and maintaining consistent air pressure between the inside and outside. Then, the filling pipe 78 injects the solvent into the inner tank 73. The graduations on the outer surfaces of the feeding tank 7 and the inner tank 73 are observed. After the required amount of solvent is introduced, the piston block 75 is moved to inject the solvent into the mixing tank 3. By using vent 791, the air pressure inside and outside the inner tank 73 is balanced when the inner tank 73 is empty. This prevents the inner tank 73 from being pressurized when it is completely sealed, thus avoiding any pressurization issues with the inner tank 73 itself or its bottom discharge valve when filling it with material. Excessive pressurization could cause the piston block 75 to move upwards, affecting the operation of the piston block 75 lifting mechanism. It could also affect the operation of the valve at the bottom of the inner tank 73, and damage to the valve could lead to errors in subsequent material feeding.

[0028] A guide pipe 77 is installed at the bottom of the inner tank 73, connecting the feeding tank 7 and the mixing tank 3. A diaphragm valve 76 is installed on the guide pipe 77. When the piston block 75 moves downward, the inner tank 73 is completely sealed when it reaches the bottom of the exhaust layer 79. This allows the solvent raw material inside the inner tank 73 to be fed into the mixing tank 3 through the guide pipe 77. The diaphragm valve 76 effectively prevents the solvent inside the guide pipe 77 from flowing back when the piston block 75 moves upward and suction is generated inside the inner tank 73. This ensures the accuracy of quantitative feeding into the mixing tank 3. A main shaft motor 5 is fixedly installed at the bottom of the welded frame plate 13. The mixing tank 3 is fixedly installed to the base frame 1 via two sets of mounting seats 32. End caps 31 are installed at both ends of the mixing tank 3. An agitator 33 is installed inside the mixing tank 3, and the output end of the main shaft motor 5 is connected to the agitator 33 through the mixing tank 3. Bearing seats are installed at the other end of both the agitator 33 and the lead screw 61. The output end of the main shaft motor 5 is connected to the stirring paddle 33, which drives the stirring paddle 33 to rotate, thereby achieving the mixing effect of the raw materials inside the mixing tank 3.

[0029] A delivery pump 2 is fixedly installed on the base frame 1 at the bottom of the mixing tank 3. A support base 11 is installed at the bottom of the base frame 1. A mounting groove 12 is provided on the base frame 1, and the delivery pump 2 is fixedly installed on the mounting groove 12. One end of the delivery pump 2 is connected to the bottom of the mixing tank 3 through a discharge pipe 34. Solenoid valves 8 are installed on both the discharge pipe 34 and the injection pipe 78. The delivery pump 2 transports the ink raw materials that have been mixed inside the mixing tank 3 to the container for the next step.

[0030] First, the piston block 75 is moved upwards to the top of the exhaust layer 79 to ensure air circulation inside the inner tank 73 and that the internal air pressure of the inner tank 73 is consistent with that of the outside. Then, the filling pipe 78 fills the inner tank 73 with solvent. The scale readings on the outer surface of the feeding tank 7 and the inner tank 73 are observed. After the required amount of solvent is added, the drive motor 6 is started, causing the lead screw 61 to rotate. This causes the lifting frame 62, through which the thread passes, to move up and down, thereby moving the piston block 75 at the other end of the lifting frame 62 up and down to fill the mixing tank 3 with solvent. After filling is complete, the drive spindle motor 5 drives the stirring paddle 33 to rotate, achieving a mixing effect on the raw materials inside the mixing tank 3.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
