This full-automatic weighing compounding conveying system is specially developed for large-scale PVC pipe and profile manufacturers. It abandons the inefficient manual weighing, batching and material handling mode, and realizes computer integrated automatic control from raw material feeding, storage, precise weighing, mixing to final feeding to extruder. The complete system integrates multiple functional units, effectively solves the problems of low precision, high labor cost and health hazards caused by manual operation. It has stable performance and has been successfully applied in many large PVC profile production enterprises.

With the rapid development of PVC pipe and profile industry, large production factories have higher requirements for production efficiency, batching accuracy and production safety. The traditional manual batching and mixing mode is only suitable for small workshops, and it is difficult to meet the production demands of large-scale factories. Our PVC automatic weighing compounding conveying system is a customized intelligent production solution targeting the pain points of traditional production. The whole production process is controlled by computer. Raw materials such as PVC and calcium carbonate are automatically loaded, stored, conveyed, weighed and mixed, and the finished mixed materials are automatically delivered to the extruder. The system realizes unmanned operation in the batching and conveying link, standardizes the production process, and greatly improves the overall operation level of the production line. It is a necessary supporting equipment for modern large-scale PVC production workshops.
First of all, the system ensures high weighing accuracy. Different from repeated manual operation which is prone to errors and fatigue, computer automatic weighing maintains stable precision all the time, avoiding material proportion deviation and defective products. Secondly, it greatly reduces labor intensity and labor cost. The full-automatic operation mode cuts down a large number of on-site workers, and helps enterprises save long-term labor expenditure. Thirdly, it protects workers’ physical health. Chemical raw materials in PVC production will cause harm to human body, and the closed automatic conveying and mixing structure isolates workers from raw materials thoroughly. In addition, the system adopts modular design, with compact structure and stable operation. Each unit works cooperatively, the whole production flow is smooth, and the failure rate is low, which can adapt to long-term continuous industrial production.
The complete set of PVC automatic mixing and conveying system consists of seven core functional parts. They are loading station including PVC loader and calcium carbonate loader, pneumatic conveying system, special storage silos for PVC and calcium carbonate, vacuum conveyor with automatic weighing device for mixer, professional PVC mixer unit, compound storage silo and automatic feeding system for extruder. Each module is closely connected to form a closed-loop production line, realizing one-stop processing from raw materials to feeding for extrusion production.
This equipment has excellent practical application performance. A typical cooperation case is Anhui Conch Group Co., Ltd., located in Wuhu, China. The project was completed and put into use in 2014. The equipment is mainly used for the production of PVC window profiles, undertaking all links including automatic feeding, dosing and weighing, material mixing and material conveying. After putting into operation, the production efficiency of the customer’s factory was significantly improved, the product qualification rate rose steadily, and the on-site operating environment was greatly optimized, winning high recognition from the customer.
A1: It is mainly designed for large-scale factories engaged in PVC pipe and PVC window profile production. Small factories with low output can still choose manual mode, while large factories pursuing high efficiency, high precision and standardized production are the most applicable customers.
A2: Yes. The whole process from raw material loading, weighing, mixing to feeding to extruder is automatically controlled by computer. Workers only need to conduct regular inspection and equipment maintenance, and no manual batching and material handling is required.
A3: No. The system is equipped with a professional automatic weighing module, which has high and stable precision. Compared with manual weighing, it effectively avoids errors caused by human fatigue and negligence, and keeps the material ratio within the standard range for a long time.
A4: The equipment adopts mature modular structure. Each functional unit is independent and easy to disassemble and inspect. Daily maintenance work is simple, and the overall failure rate is low, which will not affect normal production.
