The application of an additional carding device overturns the traditional thinking of carding unit configuration, breaking the layout of a single carding area with a large span of the cylinder-slewing cover, which is crucial to the efficiency of the carding machine. The main performance has the following aspects.
Extending the fiber path
In order to obtain sufficient sections to deploy additional carding devices, the new carding machine generally adopts the extension fiber path to achieve it. For example, DK903, TC03, FA225, JWF1202, FA232A and other carding machines with multi-roller design, raise the cylinder to increase the angle between the licker-cylinder and doffer, such as DK803 and C51 , MK6, FA224, JWF1203, FA226 and other carding machines.
Achieve multi-section combing
Compress the number of rotary cover plates, increase the rack cover plate under the licker-in roller and the front and rear fixed rack cover carding units of the cylinder to achieve multi-section carding and improve the carding effect.
Expand carding area
The new carding machine is designed to significantly increase the carding area of the whole machine by adding the rack cover plate under the licker-in roller and the front and rear fixed rack cover plates of the cylinder.
Achieve combing area function combination
Combine carding, dust removal and cotton net cleaning functions to form an additional carding system to suit different carding areas.
Increase the actual needle area ratio in the carding area
The ratio of the length of the needle on the rotary cover to the length of the cover frame is 22 / 32.7, and the fixed cover is about 30/34. Therefore, the effective area of the latter is 21% higher than the former.
The carding is highly targeted, and the optimized configuration is more efficient.
The fiber morphology during the carding process is gradual, and a single carding element cannot meet the actual needs of different sections. Multi-section carding can optimize the design and configuration of card clothing specifications according to the fiber status of different sections and work tasks. Carding elements with different carding characteristics can be used for carding in different sections, making carding more efficient.
Swivel cover improves efficiency and longer life
After carding the lower rack cover and the rear fixed cover of the licker-in roller, the proportion of bundled fibers decreases, and the fibers entering the rotary cover-cylinder carding area are evenly distributed, reducing the filling and reducing the load. Extend, and the tooth density can be increased moderately.
Favorable and high yield
Expand the carding work surface, optimize the configuration of each carding area, make the carding more targeted and more efficient, and create conditions for high output.
Improving the quality of cotton nets and yarns
The application of multi-section carding, sub-section optimized configuration, multi-dust removal and cleaning settings, the final stage of fine carding, finishing carding, and straight fiber reinforcement provide sufficient guarantee for improving the quality of cotton nets and yarns.
