Melt pump and screen changer for PP PET strapping production line

Zhengzhou Batt melt pump for strapping is mainly used for high temperature and high viscosity polymer melt conveying, pressurizing and metering. According to the process of strapping production, Zhengzhou Batt melt pump manufacturer has improved the special melt pump for strapping; the pump is installed between the mold and the screen changer, driven by frequency conversion motor, and the use of this melt pump in the strapping production line can significantly improve the stability of width and thickness dimensions, and also increase the output, reduce the back pressure of the screw machine and extend the service life of the screw.

It is a new multi-station structure with preheating and exhausting mechanism, no pressure fluctuation when changing the net, which can guarantee the continuous production and dimensional stability of the strapping products, realize no stop, no strip, no material leakage, no influence on the production and the size of the strapping, increase production and energy saving, reduce consumption and cost. It is a cost-effective and widely used quick non-stop screen changer.

It can quickly switch screens within 1 second, fast screen changing action, small change in material flow, no material leakage, high pressure resistance (peak up to 50MPA), large filtering area, short runner, simple operation, less screen changing waste, easy and fast screen changing, no stopping to change screens. Adopting internal heating, fast heating speed, uniform temperature and small energy consumption.

Packing belt screen changer, two detachable filter stations are designed on the slide plate, when working, one filter station is inside the main body for melt filtration, and the other station is outside the main body for backup (the slide plate is equipped with stainless steel heating rods for heating and heat preservation to ensure the similarity with the production temperature). When the impurities on the filter net accumulate to a certain degree during the work, it is necessary to change the net, you can press the button of the operating handle on the hydraulic station to start the accumulator hydraulic station to change the net action.

In the face of different customers, we provide professional and considerate consultation and technical services, and customize complete sets of melt pressure stabilization and impurity removal solutions for each customer. With the rise of the biodegradable material industry, our company has concentrated its R&D efforts on the new biodegradable polymer special screen changing equipment, which is suitable for PBAT, PLA, PBS, PGA, PCL and other mainstream biodegradable materials. In recent years, we have overcome the sealing technology of extra-large polymer screen changers and specialize in the design and manufacture of various extra-large polymer screen changers. info@battemachinery.com
