PP drawing melt pump used in woven bag production line

PP brushed woven bag melt pump is a specialized equipment used in the production process of PP (polypropylene) brushed woven bags to transport, pressurize, and measure high-temperature and high viscosity polymer melt. The following is a detailed introduction to the PP brushed woven bag melt pump:

1、 Main purpose

The melt pump is mainly used for the treatment of high-temperature and high viscosity polymer melts. In the production line of PP drawing and weaving bags, it can pressurize and stabilize the high-temperature PP melt from the extruder, and then steadily send the flow rate to subsequent processes such as weaving or forming heads. This helps to ensure the dimensional accuracy of woven bags, reduce scrap rates, and improve production efficiency.

2、 Working principle

The melt pump is a positive displacement conveying device, and its working principle mainly relies on two meshing gears. When the gear rotates in the specified direction, the melt is sucked into the gear teeth and transported to the discharge area along with the rotation of the gear, and finally pressed into the outlet pipeline. Due to the continuous rotation of the pump shaft, the melt is continuously transported out, thereby achieving stable pressurization and metering.

3、 Structure and Composition

The melt pump is mainly composed of pump casing, driving gear, driven gear, sliding bearing, front and rear end plates, packing seal and other components. These components together form a sealed working chamber, ensuring the stability and safety of the melt during transportation.

4、 Performance characteristics

High stability: The melt pump can accurately control the flow and pressure of the melt, ensuring the stability and consistency of woven bag production.

High efficiency: By optimizing gear design and increasing speed, the melt pump can achieve efficient melt transportation and pressurization.

Good temperature resistance: Made of high temperature resistant materials, it can adapt to the high temperature environment of PP melt.

Strong sealing: High quality sealing materials and structures are used to ensure that the melt does not leak during transportation.

5、 Application advantages

Improving product quality: Stable melt conveying helps reduce dimensional deviations and defects in woven bags, improving overall product quality.

Reduce energy consumption: By optimizing the working conditions of the extruder, reduce back pressure and energy consumption, and improve overall production efficiency.

Extend equipment lifespan: Reduce the load and wear of extruders, and extend the service life of equipment and molds.

6、 Market and Suppliers

At present, there are multiple suppliers in the market offering PP brushed woven bag melt pump products, such as Zhengzhou BATTE Melt Pump Co., Ltd. and Tianjin Haotian Pump Industry Co., Ltd. These suppliers typically have years of production experience and professional technical teams, capable of providing customers with high-quality products and services.

In summary, the melt pump for PP woven bags plays a crucial role in the production process of PP woven bags. It can not only improve product quality and production efficiency, but also reduce energy consumption and equipment wear, making it an indispensable and important equipment in modern production lines.
