Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a magnetized separation and color mixing mixer with digital precision control function. Background Technology

[0002] In fields such as plastics processing and 3D printing material preparation, color mixing mixers are core equipment for achieving uniform mixing of materials. The mixing accuracy and material purity directly affect the quality of the final product. Existing color mixing mixers generally suffer from problems such as limited functionality, low control precision, and insufficient impurity separation capabilities, making it difficult to meet the needs of precision processing scenarios.

[0003] Traditional mixers mostly only have basic mixing functions and cannot simultaneously remove magnetic impurities such as iron filings and iron powder mixed in with materials. These impurities can cause defects in subsequent processed products and reduce the yield of finished products. Some equipment with magnetization functions have fixed magnetic components that cannot be adjusted in terms of adsorption position and magnetic field strength, resulting in adsorption dead zones. Furthermore, the magnetic field is easily shielded by the barrel wall, leading to poor separation effect.

[0004] Meanwhile, the stirring speed, time and other parameters of existing equipment are mostly manually adjusted, lacking digital monitoring and feedback mechanisms. The parameters are not accurate and cannot be matched with the process precisely according to the material characteristics, resulting in large fluctuations in the uniformity of mixing. The stirring paddles are mostly of ordinary structure, which makes the materials easy to stick together and separate, further affecting the mixing effect. Summary of the Invention

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model discloses a magnetized separation and color mixing mixer with digital precision control function, comprising a frame 1, a mixing tank 2, a mixing component, a magnetized separation component, a digital control system, and a drive module. The mixing tank 2 is fixed to the top of the frame 1, the mixing component is vertically installed inside the mixing tank 2, and the magnetized separation component surrounds the outside of the mixing tank 2. The digital control system is electrically connected to the drive module and the magnetized separation component. The mixing tank 2 has a double-layer structure, with the inner layer 3 being the mixing chamber and the outer layer 4 forming an installation cavity 5 between it and the inner layer 3. Several guide rails 6 are arranged around the inner wall of the outer layer 4. The mixing component includes a mixing motor 7, a mixing shaft 8, and a mixing paddle. The magnetized separation component includes a mounting base 13, an electromagnetic adsorption block 15, and an adjustment component. The digital control system includes a control panel 19, a PLC controller, a speed sensor 17, a magnetic field strength sensor 16, and a timer. The control panel 19 is embedded in the side of the frame 1, the PLC controller is embedded inside the control panel 19, and the speed sensor 17 is installed at the output end of the mixing motor 7.

[0021] This technical solution integrates the operating parameters of each component through a digital control system, achieving simultaneous optimization of the stirring process and magnetization separation. The stirring component drives the material to form a circulating flow, ensuring uniform mixing; the magnetization separation component is driven by a servo motor 12 to move along the guide rail 6, and works with the adjustable strong magnetic field generated by the annular magnetizer 14 to penetrate the inner layer 3 of the stirring tank 2 and adsorb magnetic impurities; the PLC controller collects data such as rotation speed, magnetic field strength, and temperature in real time, and automatically calibrates according to preset parameters, ultimately achieving an integrated function of uniform material mixing, efficient separation of magnetic impurities, and precise control of process parameters, solving the pain points of low mixing accuracy and incomplete impurity separation in traditional equipment.

[0022] The stirring motor 7 is fixed to the top center of the stirring tank 2 via a motor base, and its output end is coaxially connected to the stirring shaft 8. The stirring shaft 8 has propeller blades 9 evenly distributed along the axial direction, and the surface of the propeller blades is provided with anti-slip texture. The bottom of the stirring tank 2 has a conical structure, which is adapted to the top opening of the frame 1.

[0023] The stirring motor 7 receives speed commands from the PLC controller and outputs torque, which is transmitted to the propeller blades 9 via the coaxially connected stirring shaft 8, driving the blades to rotate at high speed. The spiral structure of the propeller blades 9 generates axial thrust, pushing the material at the bottom of the mixing tank 2 upwards, while the material at the top falls naturally under gravity, forming an upward and downward circulating flow that prevents material stratification.

[0024] The anti-slip texture on the surface of the propeller blade 9 increases the friction with the material, breaks the adhesion between material particles, and enhances the turbulence effect, allowing materials of different colors and properties to spread and blend quickly, improving the mixing uniformity to over 98%; the conical bottom design guides the material to converge towards the center, avoiding material residue at the bottom and further ensuring comprehensive mixing.

[0025] The guide rail 6 is located on the inner wall of the outer layer 4 of the mounting cavity 5 and has an adjustment groove; the adjustment component includes a servo motor 12 and a ball screw 11. The servo motor 12 drives the ball screw 11 to rotate. The mounting seat 13 is fitted onto the ball screw 11 and slides on the guide rail 6; an annular magnetizer 14 is embedded at the front end of the mounting seat 13. An electromagnetic adsorption block 15 surrounds the annular magnetizer 14 and is attached to the inner layer 3 of the mixing tank 2. A magnetic field strength sensor 16 is attached to the inner side of the annular magnetizer 14.

[0026] The servo motor 12 receives instructions from the PLC controller and drives the ball screw 11 to rotate in both directions, causing the mounting base 13 to move axially back and forth along the adjustment groove of the guide rail 6. The mounting base 13 synchronously drives the annular magnetizer 14 and the electromagnetic adsorption block 15 to move, so that the magnetic field adsorption area covers the entire height of the stirring chamber, eliminating adsorption dead zones.

[0027] When the annular magnetizer 14 is energized, it generates an adjustable strong magnetic field of 100-500mT. The electromagnetic adsorption block 15 is closely attached to the inner layer 3 of the mixing tank 2. With the non-magnetic stainless steel material of the inner layer 3, the magnetic field can efficiently penetrate the tank wall and form an annular adsorption magnetic field in the mixing chamber. Magnetic impurities in the material, such as iron filings and iron powder, overcome flow resistance under the action of the magnetic field force, move towards the tank wall and are adsorbed onto the inner wall of the inner layer 3. They are then locked in place by the outer electromagnetic adsorption block 15 through the magnetic field.

[0028] The magnetic field strength sensor 16 collects the magnetic field parameters of the annular magnetizer 14 in real time and feeds them back to the PLC controller. If the value deviates from the set value, the PLC automatically adjusts the input current to ensure that the magnetic field strength is stable at 80-450mT, which can meet the adsorption requirements of magnetic impurities with different particle sizes.

[0029] The control panel 19 is embedded in the side of the frame 1, with a built-in PLC controller, a touch screen and operation buttons; the speed sensor 17 is installed at the output end of the stirring motor 7, the temperature sensor 18 is located on the inner wall of the stirring tank 2, and the timer is integrated into the PLC controller; the PLC is electrically connected to each actuator and sensor to realize bidirectional signal transmission.

[0030] Operators can set parameters such as stirring speed, stirring time, magnetic field strength, and adsorption movement speed through the touch screen or operation buttons. After receiving the instructions, the PLC controller sends operation signals to components such as stirring motor 7, servo motor 12, and annular magnetizer 14 to specify the working parameters of each component.

[0031] Speed ​​sensor 17 collects the real-time speed of stirring motor 7, temperature sensor 18 monitors the material temperature, magnetic field strength sensor 16 provides feedback on magnetic field parameters, and timer records the stirring time. All data is transmitted to the PLC controller in real time. If the parameters deviate from the set values, such as speed fluctuations exceeding ±5 r / min or temperature exceeding the threshold, the PLC controller immediately and automatically adjusts the operating status of the components, such as increasing the current of stirring motor 7 and decreasing the magnetic field strength, forming a closed-loop control.

[0032] The touch screen displays various operating parameters and equipment status in real time, such as standby / running / complete, as well as fault alarms, such as overload and abnormal temperature, allowing operators to monitor the process in real time. It also supports parameter storage and retrieval to adapt to different material processing needs.

[0033] The electromagnetic discharge valve 20 is electrically connected to the PLC controller. After the mixing is completed, the PLC controller receives the duration signal of the timer, delays for 30 seconds to ensure that the magnetic impurities are fully adsorbed, and then sends an opening command. The discharge valve opens automatically, and the material is quickly discharged along the bottom of the cone to avoid residue. If it is necessary to interrupt the operation, it can be manually closed through the control panel 19, which is convenient to operate.

[0034] The top opening of the frame 1 is precisely matched with the conical structure at the bottom of the mixing tank 2. On the one hand, it can stabilize and fix the mixing tank 2, and on the other hand, it can guide the material at the bottom of the cone to converge towards the discharge valve, improve the discharge efficiency, and reduce material residue.

[0035] Detailed Workflow Step 1: Device Initialization and Parameter Setting Operators check equipment status: ensure the inner wall of mixing tank 2 is clean, the electromagnetic adsorption block 15 is free of residual impurities, and all components are properly connected; Input process parameters via the touch screen on control panel 19: stirring speed, such as 300 r / min; stirring time, such as 15 min; magnetic field strength, such as 300 mT; and servo motor 12 moving speed, such as 5 cm / min. Clicking the "Start" button will cause the PLC controller to receive the command, initialize all sensors, and enter standby mode after a self-test without any faults. The touch screen will then display "Ready".

[0036] Step 2: Material feeding and pretreatment Open the sealing cover of the top feed hopper 10 of the mixing tank 2, and pour the material to be mixed, such as plastic granules or powder, into the mixing chamber. The amount of material should not exceed 80% of the volume of the mixing chamber. After closing the sealing cover of the feed hopper 10, a "feeding complete" signal is sent through the control panel 19. The PLC controller records the initial state, and the temperature sensor 18 begins to collect the material temperature in real time.

[0037] Step 3: Simultaneous operation of stirring and magnetization separation The PLC controller sends a start command to the stirring motor 7, which drives the stirring shaft 8 to rotate the propeller blade 9. The material begins to form an upward and downward circulating flow, and the anti-slip texture enhances the turbulence, achieving initial color mixing. Synchronously send commands to servo motor 12 and annular magnetizer 14: servo motor 12 starts, drives ball screw 11 to move mounting base 13 back and forth along guide rail 6, annular magnetizer 14 is energized to generate a magnetic field of set intensity, and electromagnetic adsorption block 15 begins to adsorb magnetic impurities in material. During operation, each sensor collects data in real time: speed sensor 17 provides feedback on stirring speed, magnetic field strength sensor 16 calibrates magnetic field parameters, and temperature sensor 18 monitors material temperature. The data is displayed synchronously on the touch screen. If the parameters deviate from the set value, such as when the temperature rises to the 50℃ threshold, the PLC automatically adjusts, such as reducing the speed of stirring motor 7, to ensure process stability.

[0038] Step 4: Work completed and materials discharged After the timer reaches the set stirring time, the PLC controller sends a stop command, and the stirring motor 7, servo motor 12, and annular magnetizer 14 are shut down in sequence. After a 30-second delay, to ensure that the magnetic impurities are stably adsorbed onto the barrel wall, the PLC sends an opening command to the electromagnetically controlled discharge valve 20. The discharge valve opens, and the uniformly mixed material with the magnetic impurities removed is discharged along the bottom of the cone and collected into a preset container. After the material is discharged, the touch screen displays "Operation Complete". The operator then closes the discharge valve and prepares for the next operation or equipment cleaning.

[0039] Step 5: Equipment Cleaning and Standby If it is necessary to clean magnetic impurities, a "magnetic field off" command can be sent through the control panel 19. After the annular magnetizer 14 is powered off, the magnetic field disappears, the magnetic impurities lose their adsorption force, and some are discharged with the material. Rotate and remove the conical structure at the bottom of the mixing tank 2. At this time, the residual impurities inside the mixing tank 2 can be removed by wiping the inner wall of the mixing tank 2. After cleaning is complete, turn off the main power supply to the equipment. The touch screen will display "Standby" to complete the entire work cycle.
