There is a lack of dedicated devices for integrated control of quantitative addition and dispersion processes, resulting in problems such as low addition accuracy, uneven dispersion, and poor batch stability in actual production. Furthermore, existing devices lack effective linkage control between key stages such as weighing, feeding, discharging, mixing, and discharge, making it difficult to meet the automation and intelligent requirements of modern industrial production.

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses a device for quantitative addition and dispersion of colorants, such as... Figure 1 , Figure 2 , Figure 8 As shown, the colorant quantitative addition and dispersion device mainly includes a frame 1, a mounting box 2, a weighing mechanism 3, a metering hopper 4, a feeding mechanism 5, a discharge hopper 6, a discharge mechanism 7, a support frame 8, a horizontal dispersion cylinder 9, a stirring mechanism 10, a discharge mechanism 11, and a controller 12. The frame 1, as the basic load-bearing component of the entire device, is made of high-strength steel to ensure sufficient stability and vibration resistance during operation. The mounting box 2 is fixedly installed at the top of the frame 1. It is a hollow structure with openings at the top and bottom and closed on all sides, and a transparent movable door at the front for easy observation of the internal operating status and maintenance. The top of the mounting box 2 is also equipped with a platform, and protective railings are installed around it, which facilitates the placement of tools by operators and ensures operational safety.

[0021] like Figure 7 As shown, the weighing mechanism 3 is the core component for achieving accurate weighing. It includes a mounting beam 31, a connecting plate 32, and a load cell 33. The mounting beam 31 is fixedly installed inside the mounting box 2, while the connecting plate 32 is connected to the side wall of the weighing hopper 4. One end of the load cell 33 is connected to the mounting beam 31, and the other end is connected to the connecting plate 32. When the colorant enters the weighing hopper 4, the load cell 33 can monitor the weight change in the weighing hopper 4 in real time and transmit the data to the controller 12. The controller 12 determines whether to stop feeding based on a preset target value, thereby achieving precise weight control.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, the metering hoppers 4 are configured in two sets, each installed inside the mounting box 2 via a weighing mechanism 3. A feeding tray is inclined at the top of each hopper to facilitate the smooth sliding of the colorant into the hopper. A feeding port is located at the bottom of the metering hopper 4, and a feeding mechanism 5 is installed at the feeding port to control the flow of the colorant. The feeding mechanism 5 includes a mounting plate 51, a feeding plate 52, and a feeding cylinder 53. The mounting plate 51 is fixedly installed on both sides of the feeding port and has slide rails on it. The feeding plate 52 is slidably installed within the slide rails. The feeding cylinder 53 is installed at the bottom of the connecting plate 32, and its piston rod is connected to the feeding plate 52. When the feeding cylinder 53 receives a command from the controller 12, the piston rod pushes the feeding plate 52 to move along the slide rails, thereby opening or closing the feeding port and achieving precise control of the colorant.

[0023] like Figure 6 As shown, the discharge hopper 6 is installed inside the mounting box 2 via a support beam, located directly below the two sets of metering hoppers 4. Its bottom end has a discharge port, and the discharge mechanism 7 is installed at the bottom of the discharge port and extends to the outside of the mounting box 2. The discharge mechanism 7 includes a double-lobed hopper 71 and a discharge cylinder 72. The double-lobed hopper 71 is hinged to the support beam of the mounting box 2 via a pin and is located directly below the discharge port. One end of the discharge cylinder 72 is installed on one lobe of the hopper, and the other end is hinged to the other lobe. When the discharge cylinder 72 receives a command from the controller 12, it controls the opening and closing state of the double-lobed hopper 71 through a telescopic movement, thereby achieving a quantitative output of the colorant.

[0024] like Figure 3 , Figure 5 , Figure 7 As shown, the horizontal dispersion cylinder 9 is mounted directly below the discharge mechanism 7 via a support frame 8. Its interior is a hollow structure used to contain the mixture of colorant and substrate. The stirring mechanism 10 is installed inside the hollow structure and includes a rotating shaft 101, a motor 102, a connecting rod 103, and a spiral stirring blade 104. The rotating shaft 101 is rotatably mounted inside the horizontal dispersion cylinder 9. The motor 102 is mounted on the side wall of the rotating shaft 101 and is connected to the rotating shaft 101 via a transmission connection. The connecting rod 103 is fixedly mounted on the rotating shaft 101, and the spiral stirring blade 104 is mounted on the rotating shaft 101 via the connecting rod 103. When the motor 102 starts, it drives the rotating shaft 101 to rotate, which in turn drives the spiral stirring blade 104 to efficiently disperse the mixture, ensuring that the colorant is evenly distributed in the substrate.

[0025] like Figure 4 , Figure 10As shown, the bottom of the horizontal dispersing cylinder 9 has a discharge port, and a discharge mechanism 11 is installed at the discharge port to control the discharge of the finished product. The discharge mechanism 11 includes a discharge frame 111, a limiting plate 112, an arc-shaped discharge plate 113, and a discharge cylinder 114. The discharge frame 111 is fixedly installed at the discharge port of the horizontal dispersing cylinder 9, and the limiting plate 112 is installed on the discharge frame 111. A groove is formed between the bottom of the horizontal dispersing cylinder 9 and the limiting plate 112, and the arc-shaped discharge plate 113 is slidably installed in the groove. The discharge cylinder 114 is installed on the support frame 8, and its piston rod passes through the discharge frame 111 and is connected to the arc-shaped discharge plate 113. When the discharge cylinder 114 receives a command from the controller 12, it pushes the arc-shaped discharge plate 113 along the groove through a telescopic action, thereby opening or closing the discharge port and realizing the automatic discharge of the finished product.

[0026] The controller 12 is installed on the side wall of the mounting box 2 and is electrically connected to the weighing mechanism 3, the feeding mechanism 5, the discharging mechanism 7, the stirring mechanism 10, and the discharge mechanism 11. It is responsible for coordinating the operation of the entire device. In actual operation, the operator sets the target weight and operating parameters through the controller 12, and the controller 12 automatically adjusts the working status of each mechanism based on the real-time collected data.

[0027] Work process: I. Preparation Stage The operator sets the target weight of the colorant and the operating parameters of the device using the controller 12 installed on the side wall of the mounting box 2. At this time, all mechanisms of the device are initially closed, waiting for instructions to start working.

[0028] II. Feeding and Weighing Stage This device works in conjunction with a conveying system. The operator uses controller 12 to start the conveying system, delivering the colorant to the measuring hopper 4 inside the mounting box 2. The measuring hopper 4 is connected to the mounting box 2 via a weighing mechanism 3. Weighing sensors 33 in the weighing mechanism 3 monitor the weight changes of the colorant in the measuring hopper 4 in real time and transmit the weight data to controller 12. When the weight of the colorant in the measuring hopper 4 reaches the preset target value of controller 12, controller 12 issues a command, and the conveying system stops delivering the colorant.

[0029] III. Material feeding stage After confirming that the weight of the colorant in the metering hopper 4 has reached the target value, the controller 12 sends an opening command to the feeding mechanism 5 at the feeding port of the metering hopper 4. Upon receiving the command, the feeding cylinder 53 in the feeding mechanism 5 pushes the feeding plate 52 to move along the slide rail on the mounting plate 51, opening the feeding port and allowing the colorant in the metering hopper 4 to fall smoothly into the discharge hopper 6 below.

[0030] IV. Discharge Stage Once all the colorant has fallen into the discharge hopper 6, the controller 12 sends a command to the discharge mechanism 7. The discharge cylinder 72 in the discharge mechanism 7 begins to extend and retract, controlling the double-lobed hopper 71 to open, and quantitatively discharging the colorant in the discharge hopper 6 into the horizontal dispersion cylinder 9 installed below via the support frame 8. At the same time, the substrate is added into the horizontal dispersion cylinder 9.

[0031] V. Decentralization Phase After the colorant and substrate enter the horizontal dispersion cylinder 9, the controller 12 starts the stirring mechanism 10. The motor 102 in the stirring mechanism 10 drives the rotating shaft 101 to rotate, and the connecting rod 103 mounted on the rotating shaft 101 rotates accordingly, thereby driving the spiral stirring blade 104 to efficiently disperse the colorant and substrate mixture in the horizontal dispersion cylinder 9, ensuring that the colorant is evenly distributed in the substrate.

[0032] VI. Material Discharge Stage After the mixing and dispersion are completed, the controller 12 sends an opening command to the discharge mechanism 11 at the bottom discharge port of the horizontal dispersion cylinder 9. After receiving the command, the discharge cylinder 114 in the discharge mechanism 11 pushes the arc-shaped discharge plate 113 to move along the slide groove formed by the discharge frame 111 and the limiting plate 112, opening the discharge port and discharging the finished product in the horizontal dispersion cylinder 9 into the collection container.

[0033] VII. Cyclic Operation Phase After all the material in the horizontal dispersion cylinder 9 is discharged, all mechanisms of the device return to their initial closed state, ready for the next quantitative addition and dispersion operation of colorant.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
