Problems solved by technology

PVC recycled materials need to go through cleaning, crushing, impurity removal, grinding and other processes before they can be reused. Since recycled materials often contain more impurities, these impurities affect the uniformity of the thickness of the heat shrinkable film during the stretching process of the heat shrinkable film. It may also cause the heat-shrinkable film to be broken due to uneven stress, and the removal of impurities from PVC raw materials can improve the quality of the finished heat-shrinkable film; a high-efficiency cleaning and filtering is needed for a fast-flow heat-shrinkable film production impurity removal device

Abstract

The invention discloses an impurity removal device for rapid flowing type heat shrinkage film production. The impurity removal device comprises a tank, an upper fixing plate, a drive mechanism, a filter column, a discharging pipe, a power pump, a closed annular plate and a flow guiding column. The flow guiding column is arranged above a filter cavity of the filter column and is of a conical cylinder structure with the large upper portion and the small lower portion. An annular flow guiding cavity is defined between the flow guiding column and the periphery inner wall of the filter column, andconstant filtration and impurity removal are conducted at the same time from the periphery of the filter column, and the raw material liquid filtration and impurity removal speed is increased.

Description

technical field [0001] The invention relates to an impurity removal device for rapid-flow heat shrinkable film production. Background technique [0002] Heat shrinkable film is used for sales and transportation of various products, and its main function is to stabilize, cover and protect products. Heat shrinkable film must have high puncture resistance, good shrinkage and certain shrinkage stress. Heat shrinkable film is widely used in: food, medicine, disinfection tableware, stationery, craft gifts, printed matter, hardware and plastic products, telephones , Electronic appliances and other products of the outer packaging. PVC heat shrinkable film is made of PVC raw material mixed with more than ten kinds of auxiliary materials and then blown twice. It is characterized by good transparency, easy shrinkage, high strength, shrinkage rate can be adjusted freely according to user needs, and strong operability. PVC recycled materials need to go through cleaning, crushing, impur...
