The efficient automatic production line comprises an automatic feeding mechanism, a mixing mechanism, a planetary extruder, a six-roll calendaring primary and auxiliary machine, a roll stripping mechanism, a calender roll, a roll cooling mechanism, an offcut removing mechanism, a traction roll and a sheet coiler, araw material storage device, a vacuum feeding machine and a group of auxiliary material storage devices and a group of processing auxiliary tanks are arranged in the automatic feeding mechanism, a discharging opening of the mixing mechanism is connected with a feeding opening of the planetary extruder through a feeding pipe, a discharging opening of the planetary extruder is connected with the six-roll calendaring primary and auxiliary machine through a transmission belt, and the roll stripping mechanism, the calender roll, the roll cooling mechanism, the offcut removing mechanism, the traction roll and the sheet coiler are sequentially arranged on the rear portion of the six-roll calendaring primary and auxiliary machine. The efficient automatic production line is simple in structure, reliable in design and easy to operate, the automation from raw material processing to finished product coiling is achieved thoroughly, the product processing quality is improved, and the PVC film production efficiency is also improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of thermoplastic products with high specific strength, large size and complicated appearance structure, and in particular relates to an efficient automatic production line for PVC processing and a working method thereof. Background technique [0002] The main component of PVC is polyvinyl chloride, which is light yellow, translucent and shiny. PVC, the full name is Polyvinylchlorid, the main ingredient is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million to...

Problems solved by technology

[0007] During the processing of PVC film, the edges are often processed due to the different sizes required by customers. However, most of the existing edge removal machines are unilaterally operated, and the problem of inclination is prone to occur during the processing, which affects the quality of the edge removal. , and the removed side material falls off directly to the ground and is collected manually, which not only consumes labor, but also affects the surrounding environment and the production of the equipment;

[0008] In the production process of PVC, the traction roller is mainly used for the traction of sheet raw materials. During the processing of PVC sheet, the pressure requirements on the traction roller are different due to different customer needs, different production batches, and different raw materials. The distance and pressure of the traction rollers are fixed, which will cause it to fail to meet the production requirements of the enterprise, and the PVC will often fall on both sides of the traction roller during the transmission process;

[0009] The sheet coiler is a mechanism for winding PVC after production. At present, many sheet coilers only collect single rolls. After collecting, workers must wait for the workers to remove the collected PVC film from the shelf. Coiling can only be continued after that, which not only wastes a lot of time, but also seriously affects its production efficiency;
