Recently, Ningbo Huare Machinery Manufacturing Co., Ltd. obtained an invention patent“A control method for intelligent quantitative feeding and drying system”It was authorized by the China National Intellectual Property Administration to provide innovative solutions to the industry's pain point of "excessive drying".
A headache inducing difficulty in the plastic processing industry lies in the drying process. The traditional feeding and drying system can ensure that the hopper is always in a full state, sucking material below the level and stopping when it is full. It's like the previous generation raising children, just having enough to eat and wear. With the development of the times, this model has generated many industry pain points:
Pain point 1: Destructionraw materialPerformance of
Each type of plastic has its specific drying temperature and time window. If the drying time is too long or the temperature is too high, it will cause the raw materials to overheat. Either degradation occurs, and plastic molecular chains will break under sustained high temperatures, resulting in a decrease in the mechanical strength, toughness, and weather resistance of the material. Either it affects the appearance, degradation can also cause problems such as silver lines, bubbles, yellowing, black spots, etc. on the surface of the product, which is particularly serious for transparent or light colored products.
The quality of raw materials directly affects the stability of processing, and the melt index of degraded plastics will change, resulting in unstable flowability during injection molding or extrusion molding, which is difficult to control. Changes in liquidity may lead to defects such as flash edges, material shortages, and shrinkage marks in products, resulting in a continuous increase in scrap rates.
Pain Point 2: Ineffective Energy Consumption Causes Anxiety
One is that electrical energy is wasted in vain, and repeated drying unknowingly consumes a large amount of unnecessary electricity. The second issue is that raw materials are easily degraded and can only be discarded, which increases material costs.
Is there a solution that can make the raw materials "just dry completely and never dry out"? Huare Machinery's "control method for an intelligent quantitative feeding and drying system" has achieved this breakthrough. Just like in the new era, raising children is no longer just about asking if they are full, but also about whether they are good or not, teaching them according to their aptitude.
The core idea of Huare Machinery's invention patent is to transform "always full bucket" into "on-demand quantitative". Workers only need to set two parameters on the touch screen: hourly material consumption and required drying time. The system will automatically calculate when to start drying and how much material to add, ensuring that the raw materials are fully dried when starting production.
Even more intelligently, the system also supports a 'temporary interrupt' function. When it is necessary to change the mold or stop the machine briefly, workers can pause the drying process and resume operation after a short period of recovery. If the machine stops for a long time, it will automatically restart to avoid the raw materials from burning empty in the barrel for a long time.
As a deep cultivator in the field of auxiliary machinery, Huare Machinery has always adhered to the concept of "achieving energy conservation while ensuring quality". Huare people hope that products equipped with these patented technologies can create real value for customers and safeguard Huare Machinery's continued leadership and high-quality development in the global rubber and plastic auxiliary machinery market in the future.
