  About the introduction of color doser equipment

Principle of color doser

The signal from the control box is sent to the motor, the motor starts to rotate, and the screw is driven to rotate through 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.

The pellets in up to 4 collection hoppers are divided into parts and fed into the weighing hopper in a way of increasing weight. The weighing hopper weighing platform accurately measures and controls the weight of each material, and then automatically discharges the material into the mixing chamber for full the mix of.
Advanced weighing technology
The system applies advanced and advanced weighing technology to the metering mixer, and the precise weighing sensor provides users with sub-second, millimeter-level high-precision weighing, which can be used in harsh industrial environments.
1. It has the function of permanent memory and storage 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, easy to disassemble and assemble, easy to clean and exchange;
This is a new type of color doser, which comprises a frame and a mixing hopper installed on the frame. A weighing hopper is installed on the mixing hopper, and a weighing hopper is arranged between the weighing hopper and the mixing hopper. The weight sensor, the upper part of the weighing hopper is connected to the raw material hopper, and the raw material hopper and the weighing hopper are connected and closed through a plug. The plug is connected to the first cylinder, and the first cylinder is installed in the raw material hopper. The storage hopper is connected with a rotation resistance level gauge. The mixing hopper is equipped with mixing blades, and the mixing blades are fixedly installed on the mixing shaft. The mixing shaft is connected to the rotating shaft of the mixing motor. Both the heavy hopper and the mixing hopper are equipped with solenoid valve switches. This device uses a circular plug to block the material for rough and fine compensation. The coarse feed is determined according to the time, and the fine feed is fed through the instantaneous jitter of the plug with high accuracy.

Application of color doser

The metering masterbatch machine is suitable for the automatic proportional mixing 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 the treatment of 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, and the part in contact with the raw material needs special treatment, such as the use of food-grade materials, polishing treatment, etc.
Under normal circumstances, the color doser is directly installed at the inlet of the molding machine. In order to prevent the control box from shaking with the screw action of the molding machine 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, etc.

The screw diameter is divided into four types: 12, 16, 20, and 24mm. Six models can be evolved to provide different output of 0.1 to 50 kg per hour for customers. 
select. There is also a two-color masterbatch machine, which can be combined with any two masterbatch machines according to customer needs.



color doser The stabilizing device of the color doser, the weighing pan of the mixer is symmetrically provided with weight sensors on the left and right sides, and the two weight sensors are used to support the weighing pan and its contents. The stabilizer device includes a shock-absorbing device and a counterweight. A shock-absorbing device is installed between each bracket and the fixed plate. The shock-absorbing device is a rubber shock absorbing pad, a spring shock absorbing pad or a rubber air spring. The weight is installed on the insert on either side of the front and rear ends of the weighing pan. The stabilization device of the weighing mixer uses the shock absorption device between the bracket and the fixed plate to eliminate or even eliminate the vibration of the mixing barrel, thereby eliminating and eliminating the vibration of the weighing pan, and avoiding the weighing pan from impacting the weight sensor due to vibration. Improve the accuracy of weighing, thereby improving the accuracy of the mixing ratio of raw materials in the mixer, ensuring the quality of the final product, and reducing the noise of the equipment.

Operation Guide for color doser

This machine is installed in equipment that requires weighing and mixing. The weighing time and weight should be set on the equipment to control the weighing and feeding speed.Operation matters of color doser
1. Plug in the power first, then turn on the switch, the machine will start.
2. If the discharge port is not in your desired position, the color doser must be jog until the discharge port stops at your desired position.
3. Before starting the machine, check whether the electrical appliances are normal and whether the cover of the mixing cylinder is tightly closed.
4. The controller is equipped with a standard USB2.0 interface, which can save the mixing ratio data to the U disk, which is convenient for production quality control.
5. Volume mixing metering mode increases the batching capacity; with formula storage function, up to 100 groups of formulas can be stored; hierarchical security password control and alarm history function, please turn off the machine when the alarm sounds, and check whether the raw materials are used up, or in the console Automatic system check. Note: Non-professionals, please do not repair by yourself, and report to the manufacturer of the color doser equipment to deal with the relevant failure!
