Introduction
Interpretation of the core content of the standard
This standard is equivalent to the ISO28239:2008 international standard, which standardizes the terminology system and structural principles of short fiber openers and cotton cleaners, and is applicable to the design and manufacture of short fiber pretreatment equipment such as cotton and chemical fibers.
Key Terms Analysis
| Terms | English Correspondence | Technical Definition | Typical Applications |
|---|---|---|---|
| Opening Roller 1 | opening roll 1 | With combing needles/saw teeth, used for primary tearing of raw materials | Preliminary defibration of cotton bales |
| Dust removal knife | mote knife | Key component for impurity separation | Remove large impurities such as seed shells |
| Combing plate | carding element | Card clothing pre-opening element | Fiber bundle decomposition |
Structural principle comparison
Differences between opener and cleaner
opener (single-roller structure) mainly completes the preliminary decomposition of fiber bundles, while cleaner (multi-roller structure) achieves deep impurity removal through 2-3 level opening rollers and dust removal knives.
Typical configuration comparison:
- Opener: 1 opening roller + dust removal knife
- Cotton cleaner: 3 opening rollers + guide plate + trash suction system
Implementation suggestions
Equipment selection guide
Select the working width according to the fiber type (specified in Appendix A of the standard):
- Cotton fiber: 1000-1600mm width
- Chemical fiber: 800-1200mm width
Maintenance points
Regularly check the wear of the opening roller clothing (it is recommended to check every 500 hours), and the dust removal knife angle adjustment range should be maintained at 15°-25°.
