Description

Technical Field

[0001] This utility model relates to the field of color paste production technology, specifically to a color paste quantitative proportioning system. Background Technology

[0002] Color paste is a concentrated pigment paste, made from different pigments through a rigorous processing technique involving surface treatment and coating. Depending on the solvent used, color pastes are classified as water-based, oil-based, and water-oil combined.

[0003] In the existing technology, when preparing color paste, workers usually need to mix a variety of different raw materials. When making the raw material ratio, different raw materials need to be weighed using tools. After weighing, the raw materials are put into the material box through the feed port. Then, the motor is started, so that the output end of the motor drives the stirring rod to stir the raw materials, and then the raw materials are discharged from the discharge pipe.

[0004] In practical applications, the process of weighing raw materials using other tools beforehand makes each batching of raw materials take a long time, reducing the efficiency of color paste mixing. Therefore, a quantitative color paste mixing system is needed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a color paste quantitative proportioning system that achieves accurate raw material proportioning and high proportioning efficiency.

[0006] This utility model is achieved through the following technical solution: a color paste quantitative proportioning system includes a mixing tank and a stirring mechanism disposed inside the mixing tank. The bottom of the mixing tank is provided with a first discharge port, and a first electrically controlled valve is installed on the first discharge port. A cover plate is fixedly connected to the top of the mixing tank. Two placement holes communicating with the inner cavity of the mixing tank are opened on the cover plate. A dispensing cylinder is inserted into each of the two placement holes. A support ring is fixedly connected to the top of the dispensing cylinder. A weighing sensor is disposed between the support ring and the top surface of the cover plate. The weighing sensor is fixedly connected to the top surface of the cover plate. A second discharge port is provided at the bottom of the dispensing cylinder, and a second electrically controlled valve is installed on the second discharge port. The stirring mechanism is located below the two dispensing cylinders.

[0007] This design features two mixing cylinders that can hold different ingredients. Each cylinder is supported on a cover plate by a weighing sensor. As ingredients are discharged into the mixing tank through the second discharge port, the weighing sensor monitors and calculates the weight of the discharged ingredients in real time. When the set weight is reached, the second electrically controlled valve stops the discharge, thus achieving precise proportioning of the ingredients. After entering the mixing tank, the ingredients are mixed by the stirring mechanism and discharged through the first discharge port. This design is convenient and highly efficient.

[0008] As an optimization, the cover plate is detachably fixed to the mixing tank. This optimization facilitates disassembly and assembly for internal maintenance.

[0009] As an optimization, several feed pipes are fixedly connected to the side wall of the mixing tank, and the feed pipes communicate with the inner cavity of the mixing tank. This optimized solution allows other auxiliary reagents to be directly added to the mixing tank for mixing through the feed pipes, making it convenient to use.

[0010] As an optimization, a level gauge is fixedly connected to the side wall of the mixing tank. This optimization scheme uses the level gauge to monitor the material level inside the mixing tank, making it easier for personnel to control the material quantity.

[0011] As an optimization, the stirring mechanism includes a laterally extending stirring shaft, which is rotatably connected to the side wall of the mixing tank. Multiple stirring rods are evenly distributed and fixed to the outer wall of the stirring shaft, and a motor that drives the stirring shaft to rotate is fixed to the outer wall of the mixing tank. This optimized solution uses a motor to drive the stirring shaft to rotate, thereby causing the stirring rods to stir.

[0012] As an optimization, a supporting partition is fixed to the inner wall of the mixing tank. The supporting partition is located between the two batching cylinders, with its upper end in contact with the cover plate and its lower end positioned above the mixing mechanism. This optimized solution uses the supporting partition to support the cover plate, thereby improving the support strength and stability of the cover plate.

[0013] As an optimization, a viewing window is provided on the side wall of the mixing tank. This optimization allows personnel to easily observe the mixing state of the materials inside.

[0014] The beneficial effects of this invention are as follows: Different ingredients can be added to the two mixing cylinders. The mixing cylinders are supported on the cover plate by weighing sensors. When the mixing cylinders discharge ingredients into the mixing tank through the second discharge port, the weighing sensors can monitor and calculate the weight of the discharged ingredients in real time. When the set weight is reached, the second electrically controlled valve stops the discharge, thereby achieving quantitative proportioning of the ingredients. After the ingredients enter the mixing tank, they are mixed by the stirring mechanism and discharged from the first discharge port, making it convenient to use and more efficient.

[0015] By installing a viewing window on the mixing tank, it is easy for personnel to observe the mixing state of the materials inside. Attached Figure Description

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] like Figures 1-5 As shown, a color paste quantitative proportioning system includes a mixing tank 1 and a mixing mechanism disposed within the mixing tank 1. Support legs (not shown) are fixed to the outer wall of the mixing tank 1. A first discharge port 15 is provided at the bottom of the mixing tank 1, and a first electrically controlled valve 16 is installed on the first discharge port 15. Material is discharged from the mixing tank 1 through the first discharge port 15, and the material discharge is controlled by the first electrically controlled valve 16.

[0025] The top of the mixing tank 1 is fixedly connected to a cover plate 2. The cover plate 2 has two placement holes 4 that communicate with the inner cavity of the mixing tank. A batching cylinder 5 is inserted into each of the two placement holes 4. A support ring 6 is fixedly connected to the top of the batching cylinder 5. A weighing sensor 7 is provided between the support ring 6 and the top surface of the cover plate 2. The weighing sensor 7 is fixedly connected to the top surface of the cover plate 2. A second discharge port 8 is provided at the bottom of the batching cylinder 5. A second electric control valve 9 is installed on the second discharge port 8.

[0026] Two mixing cylinders 5 can be filled with different proportions of ingredients. The mixing cylinders 5 are supported on the cover plate 2 by the weighing sensor 7. When the mixing cylinders 5 discharge the ingredients into the mixing tank 1 through the second discharge port 8, the weighing sensor 7 can monitor the weight of the discharged ingredients in real time. When the set weight is reached, the discharge is stopped by the second electric control valve 9, thereby realizing the quantitative proportion of the ingredients.

[0027] Specifically, the cover plate 2 is detachably fixed to the mixing tank 1. In this embodiment, the mixing tank 1 has a rectangular box structure, and a rectangular flange 3 is fixed to the top of the mixing tank 1. The cover plate 2 is a rectangular plate, and the outer diameter of the cover plate 2 is adapted to the outer diameter of the rectangular flange 3. The cover plate 2 and the rectangular flange 3 are connected by bolts to realize the detachable fixed connection between the cover plate 2 and the mixing tank 1, which facilitates disassembly and internal maintenance.

[0028] In this embodiment, the outer diameter of the mixing cylinder 5 is smaller than the diameter of the placement hole 4, so that the mixing cylinder 5 can be freely inserted into the placement hole 4. The lower end of the mixing cylinder 5 is inserted into the mixing tank 1, so that the second discharge port 8 directly discharges the ingredients into the mixing tank 1. The discharge of ingredients can be controlled by the second electric control valve 9.

[0029] The inner wall of the support ring 6 is fixedly connected to the outer wall of the dispensing cylinder 5. The outer diameter of the support ring 6 is larger than the diameter of the placement hole 4, so that the dispensing cylinder 5 can be supported on the cover plate 2 through the support ring 6. The support ring 6 and the cover plate 2 are supported by weighing sensors 7, which enable real-time monitoring of the weight change of the dispensing cylinder. In this embodiment, four weighing sensors 7 are evenly distributed circumferentially at the bottom of the support ring 6. The weight of one dispensing cylinder 5 is detected by the four weighing sensors 7, which improves the accuracy of weight detection.

[0030] Preferably, a supporting partition 13 is fixedly connected to the inner wall of the mixing tank 1. The supporting partition 13 is located between the two batching cylinders 5. The front and rear ends of the supporting partition 13 are fixedly connected to the inner walls of the opposite sides of the mixing tank 1, respectively. The upper end of the supporting partition 13 contacts the cover plate 2, and the lower end of the supporting partition 13 is located above the mixing mechanism. The supporting partition 13 supports the cover plate 2, thereby improving the support strength and stability of the cover plate.

[0031] The stirring mechanism is located below the two mixing cylinders 5. Specifically, the stirring mechanism includes a laterally extending stirring shaft 11, which is rotatably connected to the side wall of the mixing tank 1. Multiple stirring rods 12 are evenly distributed and fixed to the outer wall of the stirring shaft 11, and a motor 10 for driving the stirring shaft 11 to rotate is fixed to the outer wall of the mixing tank 1. The stirring shaft 11 is driven to rotate by the motor 10, thereby causing the stirring rods 12 to stir.

[0032] Preferably, a plurality of feed pipes 17 are fixedly connected to the side wall of the mixing tank 1, and the feed pipes 17 communicate with the inner cavity of the mixing tank 1. In this embodiment, two feed pipes 17 are fixedly connected to the side wall of the mixing tank 1, and the height of the feed pipes 17 is lower than the height of the second discharge port 8. Other auxiliary additives can be directly added to the mixing tank 1 for mixing through the feed pipes 17, which is convenient to use.

[0033] Preferably, a level gauge 14 is fixedly connected to the side wall of the mixing tank 1. In this embodiment, the height of the level gauge 14 is lower than the height of the feed pipe 17. By monitoring the material level in the mixing tank 1 through the level gauge 14, it is convenient for personnel to control the material quantity and avoid the material level from exceeding the second discharge port 8, which would cause the material level to be too high and thus affect the discharge of the batching.

[0034] Preferably, the mixing tank 1 has a viewing window 18 on its side wall, which facilitates personnel to observe the mixing state of the materials inside.

[0035] This system also includes a PLC controller. The weighing sensor 7, the first solenoid valve 16, the second solenoid valve 9, and the motor 10 are all electrically connected to the PLC controller, thereby realizing automatic weighing, proportioning, and stirring. The control program of the PLC controller can be programmed by technicians in related fields, and will not be elaborated further here.

[0036] The working principle of this device is as follows: Operators can pre-set the discharge weight of the ingredients in the two batching cylinders 5 using a PLC controller for quantitative mixing. The PLC controller controls the opening of two second-level solenoid valves 9, allowing the two batching cylinders 5 to discharge the preset weight of ingredients. When the discharge weight is detected by the weighing sensor 7 and reaches the set value, the PLC controller controls the two second-level solenoid valves 9 to close. The PLC controller then controls the motor 10 to drive the stirring mechanism to mix the ingredients. After mixing for a certain period, the PLC controller controls the opening of the first solenoid valve 16, allowing the mixed ingredients to be discharged.
