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 slider-adjustable heat-shrinkable film production impurity removal device that is convenient for cleaning and filtering is needed

Abstract

The invention discloses an impurity removal device for sliding block adjusting 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, a sliding block, a guiding column, sliding screws and locking nuts. The guiding column is arranged at the upper end in the filter column. A guiding groove is formed in the upper end of the sliding block. The sliding block is in cup joint to the guiding column at the upper end in the filter column through the guiding groove in the upper end. Each of the two sides of the upper end of the sliding block is provided with one sliding screw. The upper ends of the sliding screws penetrate through the outer side of the upperend of the filter column. The outer side of the upper end of each sliding screw is in threaded connection with one locking nut. The sliding block can slide up and down in the filter column, accordingly, the sliding block can be adjusted to the proper liquid level position for filtration, and usage is more flexible.

Description

technical field [0001] The invention relates to a slider-adjustable impurity removal device for 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,...
