Product Description
55kw XJP-120 Rubber Hot Feed Extruder
Professional rubber extrusion equipment designed for tire tread rubber extrusion and rubber inner tube manufacturing applications.
Hot Feed Extruder Overview
The inner tube hot feed extruder is specialized equipment for producing tire inner tubes using a hot feeding process that requires preheating of rubber compound. It forms continuous inner tube blanks through screw extrusion.
Main Structure and Components
- Feeding System: Hot feed port receives preheated rubber compound (60-80°C) with forced feeding rollers for uniform material entry
- Extrusion System: Single screw structure with small length-to-diameter ratio (4-6:1) and low compression ratio (1:1.2-1.4) adapted for hot rubber characteristics
- Barrel: Built-in heating/cooling channels to maintain stable temperature (80-100°C)
- Die Head: Annular die for tubular blank extrusion with adjustable diameter for different specifications
- Auxiliary Equipment: Cooling water tank, traction device, and fixed-length cutting machine
Working Principle
- Rubber preheating in open mixer to achieve soft, plastic state
- Forced feeding through rollers into screw mechanism
- Extrusion molding through annular die to form tubular blanks
- Cooling and shaping in water tank to prevent deformation
- Fixed-length cutting for subsequent vulcanization process
Application Characteristics
Applicable Products: Automotive/motorcycle inner tubes (butyl rubber, natural rubber), bicycle inner tubes, and various inflatable rubber products including airbags and lifebuoys.
Technical Advantages: High stability with hot feeding process avoiding pressure fluctuations, strong material adaptability, and high production efficiency with continuous extrusion.
Limitations: Requires pre-heating equipment (increased energy consumption) and limited flexibility when changing rubber specifications.
Hot Feed vs Cold Feed Extruder Comparison
| Comparison Item | Hot Feed Extruder | Cold Feed Extruder |
|---|---|---|
| Material State | Pre-heated (60-80°C) | Fed directly at room temperature |
| Screw Design | Short screw, low compression ratio | Long screw, high compression ratio (1:1.5-2.0) |
| Energy Consumption | Higher (requires pre-heating) | Lower |
| Applicable Materials | Natural rubber, butyl rubber, etc. | Better for synthetic rubber (e.g., EPDM) |
| Application Scenarios | Inner tubes, thick-walled products | Sealing strips, wire & cable (complex profiles) |
