The central feeding system is composed of many large and small equipment. Therefore, generally speaking, the installation of the central feeding system requires planning and design of the entire workshop. Workshop planning and design affects the use efficiency of the central feeding system to a certain extent. So, what should be paid attention to when planning the central feeding system?
1. The feeding equipment of the central feeding system tank should be as close as possible to the injection molding machine. At the same time, the vacuum pumps of the central feeding and drying system should be put together, and a spare vacuum pump should be equipped.
2. The design of the raw material conveying pipeline of the entire central feeding system and drying system should minimize the number of elbows and the use of hoses, and try to avoid the vertical arrangement of the raw material conveying pipeline. Generally, there are two ways to choose from the central feeding system raw material from the drying tank to the injection molding machine:
1. Each injection molding machine leads a dedicated pipeline to the material selection station of the central drying system, and then chooses which drying material tank to go to.
2. Each drying tank leads out a common pipeline, and the central feeding system reserves a quick connector for each unit, which can be switched according to the needs of the product.
3. The proportion of raw materials and recycled materials, raw materials and raw materials, generally has two types: volumetric and weighing:
1. The volumetric type uses a proportional mixing valve to switch proportionally according to time;
2. If there are more than two kinds of raw materials to be mixed, or a precise mixing ratio is required, the weighing type is recommended.
There are also many kinds of mixing time. It can be mixed before entering the drying tank, or after exiting the drying tank, or mixed on the feeder of the injection molding machine. It should be analyzed according to the actual situation. select.
The above are the things that need to be paid attention to when the central feeding system is planned and designed in the workshop. The planning and design of the workshop should be done before the installation of the central feeding system. Once the installation is completed, it is impossible to modify the workshop design. Therefore, The planning and design of the central feeding system in the workshop deserves everyone's attention.
