Pre-carding plate for carding machine with suction port

Abstract

The invention discloses a pre-carding plate for a carding machine with an air suction port, which comprises a first aluminum frame, a second aluminum frame, and a hoisting rack, the first aluminum frame and the second aluminum frame are provided with the lifting rack through special screws, adjusting turnbuckles and rivet nuts. The second aluminum frame is provided with a cotton supporting plate connector, the first aluminum frame and the second aluminum frame are fixedly arranged on an adjusting seat through inner hexagon screws, the bottoms of the first aluminum frame and second aluminum frame are fixedly connected with the adjusting seat through an eccentric adjusting shaft, a connecting plate and inner hexagon screws, according to the invention, the structure is simple, the design is reasonable, a prior press-fitting pre-carding plate rack is changed to a hoisting rack to be assembled, a suction port design is added in the middle position of the two racks after the design of the intermediate batten is removed, and on the condition that the whole carding area is not changed and the mounting structure is consistent with the prior design, a suction port design is added, so that the fiber can improve the removal effect of the cotton knot, impurities and linters during the carding process, and the carding effect of the fiber is improved, thereby improving the yarn forming quality.

Description

technical field [0001] The invention relates to a pre-carding board, in particular to a pre-carding board for a carding machine with an air suction port. Background technique [0002] According to relevant research, the orientation angle of 70% of the fiber bundles on the licker-in roller is 5 0 Within (relative to the machine direction), the use of the carding plate can improve the orientation of the fiber bundles, laying a good foundation for the cotton flow to enter the carding area of ​​the cylinder flat plate for fine carding. The pre-carding plate has a carding effect on the fibers on the licker-in roller. Studies have shown that after using the carding plate, the carding force between the cylinder and the cover plate decreases, and the cotton bundles decrease, indicating that the carding plate has a carding effect. [0003] A pre-carding board is installed under the licker-in roller, which can turn large cotton blocks into small cotton blocks, so the pre-carding boar...

Problems solved by technology

After the fibers are carded by the pre-carding board, impurities and short fibers are removed again in the second trash area between the cotton support board and the small drain bottom. Since the relative position of the second trash area is relatively small, coupled with the pre-carding The entire carding surface composed of the two racks and the layering bars of the board is relatively large, and the entire carding area under the entire take-in roller has fewer removal points for impurities and short fibers, which affects the ability of the carding board to separate the neps and impurities and short fibers after fiber opening. removal of
