The head end of each connecting rod is provided with a fixed first positioning block, a moveable second positioning block. The second positioning block is fixed by a nut. One face of each needle sheet is provided with a plurality of U-shaped needle placing grooves. The longitudinal depth and width of each needle placing groove are equal to the maximum diameter of the needle, and the horizontal depth of the needle placing groove is smaller than the length of the needle. A plurality of through holes for passing the connecting rods is installed below the U-shaped needle placing grooves. The needles are placed in the needle placing grooves according to the mode that the point of the needle faces to the outside. The traditional needle plate is replaced by the needle plate formed by a plurality of the needle sheets, the needle sheet with the damaged needle is replaced by new needle sheet while the needle needs to be replaced, the operation is simple and convenient without hurting people, and the needle changing time is saved.

Description

technical field [0001] The invention relates to the textile field, in particular to a needle board. Background technique [0002] Needle boards, mainly for jute and flax carding machines. Generally, it is made of steel needles planted on arc-shaped wooden boards, and aluminum alloy can also be used instead of wooden boards, which can prolong the service life. If the needles are worn or broken, the needles need to be pulled out manually or tapped with a hammer. It is not only difficult to operate, and people are easily injured, but also takes a long time to change the needle, which affects the normal operation of the work. On the other hand, if it is a pinhole guideline, because it is a through hole, there is no focus on the bottom, and the needle is easy. Save up. Contents of the invention [0003] Aiming at the above problems, the present invention provides a needle plate which is convenient for needle replacement, low in cost and not easy to accumulate.
