PP Fiber Drawing Automatic Mesh Belt Screen Changer

The PP Fiber Drawing Automatic Mesh Belt Screen Changer is a critical piece of equipment used in the production process of PP (polypropylene) fiber drawing. Its primary function is to automatically and continuously change the screen mesh to ensure the continuity and stability of the production process. Below is a detailed introduction to the PP Fiber Drawing Automatic Mesh Belt Screen Changer:

I. Structural Composition

The PP Fiber Drawing Automatic Mesh Belt Screen Changer mainly consists of the following key components:

Mesh Belt with Differential Weave: Used for continuously and automatically changing the screen mesh. It is the core component that realizes the automatic screen-changing function.

Screen Mesh Box: Houses and supports the screen mesh, ensuring effective filtration of impurities and particulate matter as the melt passes through.

Inlet Cooling Section and Outlet Cooling Section: Achieves melt sealing and cooling through water cooling, ensuring smooth screen-changing operations.

Main Flow Channel Connection Section: Connects various components to ensure smooth melt flow during screen changing.

Electronic Control System: Controls the automatic operation of the screen changer, including the movement speed and distance of the screen mesh, as well as the operation of the heating and cooling systems.

II. Operating Principle

The PP Fiber Drawing Automatic Mesh Belt Screen Changer adopts water-cooled sealing and utilizes melt pressure or time to control the mesh movement. When the pressure or time reaches the set value, the control system automatically activates the heating device at the outlet end. After reaching the set temperature, the mesh belt, carrying impurities and waste within the melt, is ejected from the screen changer under the melt's own pressure. The melt pressure then drops to normal working levels, and the control system automatically stops heating. The outlet end is sealed by water cooling solidification, completing the mesh movement process fully automatically.

III. Advantages and Features

Automatic Screen Changing: Eliminates manual operation, improving production efficiency and reducing worker labor intensity.

No Pressure Fluctuation: During screen changing, there is no fluctuation in material pressure and flow, achieving constant pressure production with no impact on product quality.

No Wear and No Material Leakage: With water-cooled sealing, the distance and speed of screen mesh movement can be freely set, allowing flexible mesh movement without wear or material leakage, ensuring production continuity and stability.

High Efficiency and Energy Saving: Uses internal heating with high thermal efficiency. Coupled with a circulating cooling water system, it conserves water, is environmentally friendly, and reduces production costs.

Novel Structure and Easy Installation: Occupies little space, is easy and simple to install, and facilitates user maintenance and servicing.

IV. Application Scenarios

The PP Fiber Drawing Automatic Mesh Belt Screen Changer is widely used in the production of raw materials such as PP, PE, ABS, PS, and PMMA. It is particularly suitable for the production of long-process products such as fiber drawing, sheet materials, cast films, plates, and some new material pipes.

In summary, the PP Fiber Drawing Automatic Mesh Belt Screen Changer plays a crucial role in the plastic product production process due to its unique structure and advantages. It is one of the indispensable pieces of equipment in the modern plastic processing industry.
