Force Feeding Single Screw Rubber Extruder Machine With Strainer

A force-feeding single-screw rubber extruder machine with a strainer is a specific type of rubber extrusion equipment that combines the functions of feeding raw rubber material and removing impurities using a straining mechanism.

Here's a breakdown of the key components and processes involved:

1. Feeding System: The force-feeding single-screw rubber extruder machine is designed with an efficient feeding system to introduce the raw rubber material into the extruder. This system typically consists of a hopper where the rubber material is loaded and a feeding mechanism that ensures a consistent and controlled supply of rubber into the extruder.

2. Single Screw: The extruder features a single rotating screw that is responsible for conveying and processing the rubber material. The screw is designed with a specific configuration, including varying flight depths and pitch, to facilitate the desired mixing, shearing, and melting of the rubber.

3. Straining Mechanism: Incorporated within the extruder, usually at the beginning of the screw, is a strainer or a screen changer. This component is designed to remove impurities and foreign particles from the rubber material as it is forced through the machine. The strainer can be a screen pack or a continuous belt-type filter that traps contaminants while allowing the rubber to pass through.

4. Heating and Cooling Zones: The extruder is equipped with heating and cooling zones along the barrel length to control the temperature of the rubber material. Heating elements, such as electric heaters or steam jackets, raise the temperature to soften the rubber for processing, while cooling systems, such as water cooling, maintain the desired temperature profile to prevent overheating or degradation.

5. Die and Die Plate: At the end of the screw, the extruder is equipped with a die and die plate. The die determines the final shape and dimensions of the extruded rubber product, while the die plate helps control the flow and pressure distribution of the rubber material.

6. Downstream Equipment: Depending on the specific application, the extruded rubber may undergo further processing or finishing steps. This can include cooling, calibration, cutting, or coiling systems, which are typically integrated into the extrusion line after the extruder.

Force-feeding single-screw rubber extruder machines with strainers are commonly used in the rubber industry when processing materials that contain impurities or contaminants. The straining mechanism helps ensure the quality and purity of the final extruded rubber product by removing unwanted particles during the extrusion process.

This equipment has the characteristics of high production capacity, low temperature of the rubber material, low power consumption, good mixing quality, and uniform plasticization. It can evenly and stably extrude rubber materials of various mouth shapes with one bolt, so it can be widely used. Extrusion molding of hoses, inner tubes, tapes, inner linings, sealing strips, wire connections, sheaths, side tables, sub-mouth glue, etc.
