Product Introduction
The JWF1458A/JWF1457 AUTO-DOFFING ROVING FRAME is a full-automatic external doffer roving frame; it can be used alone or in conjunction with roving transfer system to constitute a roving and spinning unit. The.machine provides up to 216 spindles/224 spindles
Technical highlights
-
External automatic doffer system
Hight efficiency: low failure rate/ Doffing system can be maintained andrepaired without affecting normal operation of the roving system.
100%Hight success rate: the success rate of doffing/empty and full tubeexchange/spinning in is almost 100%.
-
There are two types. One is with threerollers. The other one is with four rollers
Standard configuration: Chinese YJ-40Aspring-loaded drafting system.
Optional configuration: Germany Texpartsspring-loaded drafting system.
Germany Suessen spring-loaded draftingsystem.
-
Drive in groups
The lower spindle rail tube drives the spindles in groups withcircle-arc tooth belt. lt makes it possible for long roving frames Smooth transmission, low noise, high speed (pure cotton spinning spindle speed up to 1300 rpm/min).
-
Cleaning system
The cleaning system comprises the upper and lower cleaners/suction unit and dust suction device behind it. lt can effectively remove the accumulated flying and avoids yarn faults, creating favorable conditions for delivering high-grade products. Tour cleaners operating mode can be set to run cycle and intervals asneeded.
-
Spool changeover
Automatic changeover is achieved between the empty and full spools of full-automatic doffing roving frame. Theechange frequency is adjustable.
-
The operation interface is user-friendly and easy to operate
Multi-motor synchronous control for constant tension spinning.
The multi-stage speed is adopted to spin and the spinning speed can be set on the screen. Automatically keep centrifugal force constant and improve spinning quality.
Through the HMl, the state inquiry, fault finding queries. Automatic storage of fault records and stop records, etc.
With network remote operation and maintenance function. can realize network management, network diagnosis and enhanced productivity.
