Technical Field
The invention belongs to the technical field of textile machinery, and particularly relates to a flat card clothing capable of improving the fiber carding quality and a carding machine.
Background
The flat clothing is one of the main components for carding machine to realize high yield, high quality and low consumption, and has important functions of carding, impurity removal, uniformity, mixing, transfer and fiber straightening. The process of tight gauge and strong carding is widely promoted. Aiming at the current situation that the fiber properties are diversified due to the change of the production area and the quality of raw cotton, it is urgent to develop a high-efficiency cover plate card clothing to adapt to the requirements of cotton spinning factories.
When carding is carried out once, the front end of the fiber is held by the cylinder needle teeth, and the needle teeth near the toe surface of the card clothing of the cover plate mainly play a role in holding the rear end of the fiber, so that one-time carding is realized. When carding again, the needle teeth near the toe surface of the card clothing of the cover plate hold the rear end of the fiber, and the needle teeth near the heel surface mainly play a role in supporting the front end of the fiber and carding the rear end of the fiber held by the cylinder. Therefore, when carding fibers by a carding machine, the improvement of the holding effect of the needle teeth near the card clothing toe surface on the fibers, the holding effect of the needle teeth near the heel surface on the front ends of the fibers when the needle teeth near the card clothing toe surface hold the rear ends of the fibers, and the carding effect on the rear ends of the fibers grasped by a cylinder are key to the improvement of the carding quality of the fibers.
At present, there is a study of changing the needle-planting mode of the cover plate card clothing to improve the carding effect of the carding machine, chinese patent publication No. CN201433261Y (publication No. 2010, 03 and 31), the invention creates a cover plate with thin, medium and dense areas of card needles in the width direction, and six layers of rubber surface D areas are arranged at the bottom of the cover plate. The carding machine has the advantages that carding action on the rear end of the fiber grasped by the cylinder is enhanced by a cover plate needle implantation mode, and the carding machine has the defect that the technology cannot actively improve the capability of grasping the fiber by the cover plate of the carding machine and the action of holding the front end of the fiber by the needle teeth of the cover plate. At present, there is also research on arranging rack cover plates with different card clothing heights to improve carding effect of carding machine, such as chinese patent publication number CN205347660U (publication date 2016, 06 and 29), the invention creates a rack cover plate card clothing for carding machine, the application discloses a rack cover plate card clothing formed by arranging different total tooth plates at equal ratio intervals, the invention realizes opening and carding cotton bundles with different sizes through the change of rack heights, and reduces load of main carding area of cylinder cover plate, which is not only in that grabbing, holding and carding effect of cover plate card teeth of carding area on fibers is still to be improved.
