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, easy-to-clean and filter-friendly telescopic adjustable heat-shrinkable film production impurity removal device is needed

Abstract

The invention discloses an impurity removal device for telescopic adjusting type heat shrinkage film production. The impurity removal device comprises a tank, an upper fixing plate, a drive mechanism,a filter mechanism, a discharging pipe, a power pump, a closed annular plate and a positioning assembly. The filter mechanism is formed through sequential up-down connection of an upper connecting cover, a telescopic pipe and a connecting base. Through the up-down telescopic movement of the telescopic pipe, the filter length is changed, accordingly, the length of the telescopic pipe can be adjusted according to the filter raw material amount, in addition, the size of filter holes can be changed through stretching and contracting of the telescopic pipe, filter precision control is achieved, and after adjustment is finished, locking nuts on penetrating connection screws are clamped to the upper side and the lower side of a penetrating connection plate.

Description

technical field [0001] The invention relates to an impurity removal device for stretching and adjusting 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, c...
