Masterbatch machine

Monochrome master machine	Multi-color masterbatch machine

The metering masterbatch mixer is suitable for the automatic proportioning and mixing of new materials, secondary materials, masterbatch or additives.

Masterbatch machine features

The metering masterbatch machine is suitable for the automatic proportioning of new materials, secondary materials, masterbatch or additives, and the error value is not higher than ±1%. At present, the standard model of masterbatch mixer cannot be used for the treatment of all kinds of plastic powder masterbatch and all kinds of food, chemicals, flammable, explosive and volatile materials. If the customer's product is the optical industry product, such as PC, PMMA, etc., the standard masterbatch machine model cannot be selected. The part in contact with the raw material needs special treatment, such as the use of food-grade materials, polishing treatment, etc.

The standard configuration

1. With the permanent memory and storage function of data;
2. Using DC brushless motor, no maintenance required;
3. Using microcomputer control, intelligent and precise calculation;
4. It can meet the requirements of external signal input at the same time;
5. The screw is chrome-plated, which is durable;
6. Modular assembly structure, convenient disassembly and assembly, easy to clean and exchange;

Optional configuration

1. When the customer is equipped with a dryer of 100KG or below, a large base is required;
2. CM series masterbatch machine can add up to four kinds of masterbatch;
3. Standard stirrer or stainless steel stirrer can be selected to meet customers' double mixing requirements;
4. The main hopper is optional to facilitate customers to add main raw materials;

Scope of application

In general, the metering masterbatch machine is directly installed at the inlet of the molding machine. In order to prevent the control box from shaking with the action of the molding machine screw and causing the loosening of related accessories, it is recommended to fix the control box on a bracket. The motor reduction ratio of this product is divided into 30:1 and 50:1, and the screw diameter is divided into four types: 12, 16, 20, and 24mm. It can evolve into six models to provide customers with different output from 0.1 to 50 kg per hour. select. There is also a two-color masterbatch machine, which can be combined with any two masterbatch machines according to customer needs.

working principle

The signal from the control box is transmitted to the motor, the motor starts to rotate, and the screw is driven by the coupling. The color masterbatch in the hopper falls into the drop rod, is squeezed by the screw, and is conveyed to the base by the screw, so as to achieve the purpose of accurately metering and conveying the color masterbatch.

Specification Table

Note: 1) * means the output size is determined according to the model selected by the customer, please refer to the data of the monochrome machine;
2) ** means the outer diameter of the screw depends on the customer's selection;
3) The single color machine is equipped with a stirrer, and "MS" is added to the back of the model;
4) The output of the above models is based on the data of the color master particles with a specific gravity of 1.2 and a diameter of 2~3mm in a continuous operation mode as the test standard;
5) The voltage specification of the machine is: 1Φ, 220V, 50HZ.

Masterbatch machine Precautions

1. Keep the machine clean and sanitary every day;
2. Add butter and lubricating oil to the moving parts of the machine regularly;
3. Regularly check whether the connecting screws of each part of the machine are loose;
4. Start the motor to check if there is any abnormal sound during operation;
5. Regularly check whether the lines of the machine are damaged;
6. Check the validity and completeness of each button on the machine;
7. Regularly check whether there is paint peeling or rust on the exterior of the machine;
8. Regularly check whether the material box of the machine is leaking;
9. Regularly check whether the transmission belt of the machine is damaged;
10. Regularly check whether the rotating blades are worn and cleaned;
11. Daily check whether the machine stopper is effective;
Common fault types and maintenance methods for weighing master batch machines:
The weighing mastering machine system receives the displacement and speed commands issued by the numerical control system. After transformation, amplification and adjustment, the motor and mechanical transmission mechanism drive the machine tool coordinate axis, the main shaft drives the worktable and the tool post, and the tool is driven by the axis linkage Relative to the workpiece, a variety of complex mechanical movements are generated to process the workpiece required by the user.
The weighing-type masterbatch machine system is an electric drive control system with the drive equipment of mechanical motion-the motor as the control object, the controller as the core, and the power electronic power conversion device as the actuator. This type of system controls the torque, speed and angle of the motor, converts electrical energy into mechanical energy, and realizes the motion requirements of the motion machinery. As the actuator of the weighing masterbatch machine, the hybrid masterbatch machine system integrates power electronics, control, drive and protection, and is accompanied by digital pulse width modulation technology, special motor material technology, microelectronic technology and modern control technology. The progress has gone through many development processes. Once the mixed color master machine is started, the external fuse of the driver will be burned out and the equipment will not work.
During the inspection, the maintenance personnel found that a power tube was damaged, but because there was no information, the function of the tube was not clear. He thought it was a power-driven front push. Replaced with a power tube. After powering on, the fuse was burned again. The upper pipe is also damaged. After inspection by the maintenance engineer, the initial analysis was correct, that is, the fuse was repeatedly blown, there must be an abnormal large current in the drive, and a power tube was found to be damaged. But the role of the tube is not clear. In fact, this tube is a stepper motor power drive tube, and the stepper motor is started by high voltage, so it has to withstand high voltage and large current. The static inspection found that the resistance of the power supply to the ground in the circuit of the pulse ring distributor was very small, but there was no short circuit. According to the number of components in the circuit and its power consumption analysis, the resistance from the power supply to the ground should not be so small, so it is suspected that there are components in the circuit damaged.
When the masterbatch machine has the above-mentioned failure, don't panic. First find out where the problem is, and then prescribe the right medicine to solve the problem as soon as possible and resume normal use.
