AI Technical Summary
Existing shaft sealing sleeves are prone to dust and other impurities entering, resulting in poor sealing performance and affecting service life and airtightness.
A guide groove is set on the sealing sleeve body. The guide groove is opposite to the direction of shaft rotation. The groove has a gradually rising bottom design. Impurities are gradually discharged through the guide groove. Combined with protective clamps and water-absorbing cotton, automatic cleaning is performed. The sealing performance is monitored through sealing plugs and exhaust channels.
It enables automatic cleaning of impurities during shaft rotation, prevents wear of the sealing sleeve, promptly detects and repairs leaks, ensures sealing performance, and avoids affecting injection molding quality.
