In recent years, with the rapid development of the construction industry, urban rail transit, electrical information, communications, new energy vehicles and other industries, the demand for cables has continued to increase. However, in the current cable industry, there is fierce competition among domestic small and medium-sized enterprises, and the production capacity of low-end products is overcapacity. Foreign-funded enterprises have occupied an absolute share of the high-end market through equipment upgrades with advantages in technology and quality.
Most small and medium-sized enterprises in the cable industry have the problems of outdated production line equipment, low production capacity, and long production cycle, resulting in high operation of the factory, and are greatly affected by the price of raw materials. Under the domestic situation of vigorously promoting energy conservation and emission reduction strategies and advocating the “Internet + manufacturing” factory model, if cable manufacturing enterprises cannot improve quality and efficiency through upgrading and transformation, they will only be eliminated by the market.
How to produce newer and better quality products required by customers at low cost and high efficiency is the appeal of the entire industry.
The whole plant planning of the intelligent central conveying system realizes the automation of production and manufacturing equipment, improves product quality, builds an intelligent factory, and helps the cable industry to complete the transformation and upgrading.
The composition of the central conveying system
Because of the characteristics of high efficiency, energy saving, personalization, automation and modern factory image, the central conveying system occupies an important position in the cable, plastic granulation, new energy and other industries.
1.Central Control Station
The central conveying system adopts the central control station to automatically and centrally control all the machines, realizing the 24-hour continuous feeding operation for all the feeding units.
2. Storage and transportation
storage material
Traditional warehousing, limited by the handling method and convenient operation, raw material bags cannot be stacked too high, resulting in a large area for raw material storage. For the storage of raw materials, we can provide small storage barrels suitable for indoor storage tank or a large outdoor silo is used to store raw materials, allowing the factory to save space, prevent raw materials from getting damp, and reduce storage costs.
transport and delivery
The bag automatic unpacking machine is used together with other conveying equipment to complete the functions of raw material transportation and storage after breaking the bag, unloading, and separating. The use of the automatic unpacking machine increases the manual unpacking of 30 bags per hour to 400 bags per hour, saving labor costs . Use positive and negative pressure fans to convey plastic raw materials, and dust-free airtight pipeline transportation equipment to prevent raw materials from being polluted.
3. Drying and dehumidification system
In the combination of double-layer thermal insulation stainless steel dryer and honeycomb rotor dehumidifier, the P.I.D temperature control system is adopted to accurately control the temperature. The honeycomb rotor can reach a dew point below -40°C, ensuring that the raw materials are fully dried and at the same time comparable to the same type. The specific energy saving is more than 30%, and the quality of the product is guaranteed during the rapid drying process.
4. Weighing and mixing system
The dried raw materials are sent to the weighing mixer for batching and mixing. The gravimetric blender of the metering and mixing system can automatically mix the main and auxiliary materials of plastic raw materials in proportion, which improves the production efficiency.
Since its establishment, Hengju Machinery has been focusing on the research and development of central feeding system, whole plant water and electricity planning, dehumidification and drying, and batching measurement, so as to make products closer to customer needs and customize perfect automation solutions for customers. It has provided stable and reliable intelligent systems for thousands of plastic manufacturers.
