I. Introduction.
In the modern injection molding process, multi-shot injection molding technology has become an important means to achieve product diversification and enhance product added value. In order to meet this demand, the multi-color group injection molding weighing mixer came into being. This kind of equipment not only integrates a precise weighing system, an efficient mixing system, but also has the function of multi-color group batching, which provides great convenience for injection molding production.
2. Introduction to multi-color injection molding weighing mixer.
Multi-color group injection molding weighing mixer is a kind of raw material handling equipment specially used for multi-color injection molding production. It accurately weighs and mixes a variety of different color raw materials according to the preset ratio through a precise weighing system and an efficient mixing system to meet the production needs of multi-color injection molding machines. The equipment has a high degree of automation and intelligence, which can greatly improve production efficiency and product quality.
3. The structure and principle of multi-color group injection molding weighing mixer.
Structure: The multi-color injection molding weighing mixer is mainly composed of weighing system, mixing system, control system and conveying system.
1) Weighing system: including a plurality of independent weighing units, each unit is responsible for the weighing of one color raw material. The weighing cell is equipped with a high-precision load cell to ensure the weighing accuracy of each color raw material.
2) Mixing system: responsible for mixing the weighed raw materials of various colors. Mixing systems usually employ high-efficiency agitators, such as spiral agitators or paddle agitators, to ensure homogeneous mixing of raw materials.
3) Control system: It is the core part of the multi-color group injection molding weighing mixer, which is responsible for controlling the operation of the whole equipment. The control system receives data from the load cell to achieve precise control of a wide range of color raw materials. At the same time, the control system also has the functions of formula storage, production data recording, etc., which is convenient for production management and traceability.
4) Conveying system: responsible for transporting the mixed multi-color group raw materials to the multi-color injection molding machine. The conveyor system usually uses equipment such as screw conveyors or belt conveyors to ensure that the material is conveyed smoothly and does not leak.
Principle: The working principle of the multi-color injection molding weighing mixer is mainly based on the load cell and control system. When the equipment is started, the control system will control the opening and closing of the weighing system according to the preset formula and weight requirements, so that the multi-color raw materials will enter the corresponding weighing unit separately. When the weighing reaches the preset value, the weighing system will send a signal to the control system, and after the control system receives the signal, it will control the mixing system to start working and mix a variety of color raw materials. During the mixing process, the control system will adjust the stirring speed and mixing time as needed to ensure the homogeneous mixing of the raw materials. When the mixing is completed, the control system will control the conveyor system to convey the mixed multi-color group raw materials to the multi-color injection molding machine for injection molding.
Fourth, the function and advantages of multi-color injection molding weighing mixer.
Function: 1) Accurate weighing: The multi-color injection molding weighing mixer adopts a high-precision weighing sensor and control system, which can realize the accurate weighing of raw materials of various colors and ensure the accurate proportion of raw materials in the production process.
2) Efficient mixing: The equipment is equipped with an efficient mixing system, which can quickly mix a variety of color raw materials and improve production efficiency.
3) Multi-color batching: The multi-color group injection molding weighing mixer can process a variety of raw materials of different colors at the same time to meet the needs of multi-color injection molding production.
4) Automatic control: Through the control system, automatic control can be realized, manual intervention can be reduced, and production stability can be improved.
5) Multiple recipe storage: The control system can store a variety of recipes, which is convenient for quick switching in the production process. At the same time, the control system can also record production data, which is convenient for production management and traceability.
6) Flexible adaptation: The multi-color group injection molding weighing mixer can be customized according to the production needs, such as adding or decreasing the weighing unit, adjusting the mixing speed, etc., to adapt to different production environments and needs.
Advantages: 1) Improve production efficiency: Through automatic control and efficient mixing, production efficiency can be significantly improved and production costs can be reduced.
2) Ensure product quality: Accurate weighing and mixing can ensure the stability and consistency of product quality.
3) Reduce manual intervention: The automatic control system can reduce manual intervention and reduce the possibility of human error.
4) Realize multi-color injection molding: Multi-color group injection molding weighing mixer can meet the needs of multi-color injection molding production, realize product diversification and improve product added value.
5) Easy to operate and maintain: The operation interface of the multi-color group injection molding weighing mixer is simple and clear, and it is easy to get started. At the same time, the equipment has a simple structure and easy maintenance.
6) Wide range of application: Because it can flexibly adapt to different production needs and environments, multi-color group injection weighing mixers have a wide range of application prospects in many industries such as plastics, chemicals, and food.
