In recent years, the continuous development of injection molding and processing industry, the growing demand for injection molded products in various industries is also increasing, thereby pushing the development and improvement of the entire injection molding and molding technology standards. However, due to the complicated equipment and personnel in the injection molding industry, Job management is often unable to cope with such a complex situation, resulting in poor management of processing materials and processing costs. This requires the application of a feed system that meets the multi-color, multi-product requirements of the product. So we all know what the characteristics of the design of the central feed system, the following to share by Xiaobian.
Central feeding system design features are:
1, Quantitative Feeding Weight Loss Feeding The characteristics of the feeder determine the feeding mode of the central feeding system agitating hopper is batch feeding. Therefore, each batch of mixing hopper feedstock will result in substantial fluctuations in the level. In order to the system of continuous and stable feed, the central feed system must be hopper material level to implement reliable automatic control.
2, the central feeding system equipment to reduce the height of installation, easy maintenance of foreign programs to lose weight measuring feeders, mixing hoppers and most of the equipment installed in a higher place (6 ~ 13m away from the ground), self-designed program weight loss measurement Feeder to leave the ground only 2 ~ 3m, mixing hopper but also 5m. Self-designed program is better, is conducive to equipment maintenance.
3, control the central feeding system of quantitative feeding. Once the material enters the screw rod, it is forcibly pushed forward. When the tough material is conveyed or the material is excessively fed, there is no room for backward movement of the material and the accident of overload stalling easily occurs. Inadequate feeding, the material instability. Therefore, the addition of the central feed system requires the installation of additional dosing devices. According to the nature of the material, the amount of extrusion volume, strict control of the amount of feed.
4, the central feeding system mixing hopper using weighing method, the material level control in real time. Normal state and abnormal state according to the production line rupture signal conversion. Stirring hopper set high level, low level, when the material reaches a high level, the total amount of mixing hopper feed decreased by 5%; Similarly, when the material reaches a low level, the total amount of mixing hopper feed Increases by 5%. Keep mixing hopper level fluctuations in this area.
In addition, the central feeding system has been widely used in the plastic production of injection molding workshop because of its characteristics of high efficiency, energy saving and personalization.
