The cutting blades are generally arranged on the side wall of the pressing strip 2 in a veneering manner or have smaller gaps, the moving range of the cutting blades can be limited by the pressing strip 2, the cutting blades positioned on two sides of the pressing strip 2 along the width direction respectively cut wool leaking out of the pressing strip 2, and finally, the cut wool bundle section is a wool sample pressed below the pressing strip 2, that is, the width of the pressing strip 2 is equal to or basically equal to the length of any wool fiber in the wool bundle section formed by cutting. According to the scheme, the pressing strip 2 is adopted to press the wool sample on the substrate 1, the width of the pressing strip 2 is taken as a reference for cutting, the cutting blade is matched to slide in parallel along the length direction of the pressing strip 2 (the length direction is perpendicular to wool fibers in the wool sample), and the two ends of the wool sample pressed below the pressing strip 2 can be cut smoothly, so that a wool bundle section with preset length and neat two end faces is obtained, and the length of each wool fiber in the wool bundle section is the same. In practical applications, wool beam segments of different lengths may be cut by replacing the batten 2 with a different width, for example, if a wool beam segment of 1cm length is to be obtained, the batten 2 with a width of 1cm needs to be replaced. The wool cutter 100 fills the blank in the prior art, and solves the problem that the length of each wool fiber in the wool bundle section is identical when the wool bundle section of 1cm is cut on a wool sample in the prior art.
In this embodiment, the cutting blades on two sides of the bead 2 along the width direction thereof are slidably connected with the bead 2 through the same U-shaped slider 3, specifically, as shown in fig. 2 and 5, a chute 21 along the length direction thereof is formed on the bead 2, the U-shaped slider 3 is straddled on the bead 2, two arms of the U-shaped slider 3 are respectively located on two sides of the bead 2 along the width direction, through holes 31 are formed on the two arms of the U-shaped slider 3, a connecting rod is connected between the two arms of the U-shaped slider 3, and the connecting rod penetrates through the through holes 31 of the two arms of the U-shaped slider 3 and passes through the chute 21 to be slidably matched with the chute 21; cutting blades are symmetrically arranged on two arms of the U-shaped sliding block 3. The synchronous cutting of the two ends of the wool bundle section can be realized by controlling the U-shaped sliding block 3 to slide along the pressing strip 2; the U-shaped sliding block 3 passes through the sliding groove 21 of the pressing bar 2 through the connecting rod and is in sliding fit with the sliding groove 21, so that the U-shaped sliding block 3 can be limited and guided, and the U-shaped sliding block 3 can be ensured to stably slide along the pressing bar 2.
In this embodiment, a mounting seat 11 is provided on one side of the base plate 1, and one end of the pressing bar 2 in the length direction is hinged with the mounting seat 11. The pressing strip 2 is turned over relative to the mounting seat 11, so that the pressing strip 2 can press or separate the wool sample on the substrate 1. When the wool sample on the base plate 1 is pressed by the pressing bar 2, the width of the pressing bar can determine the length of the cut wool bundle section, meanwhile, a guide rail is provided for the U-shaped sliding block 3, the movement of the U-shaped sliding block 3 is limited, the effect that the wool sample can not slide along with the sliding of the cutting blade when being cut is achieved, and errors caused by the fact that the cutting blade quickly slides to obtain the wool section with the consistent final length when the cutting blade cuts the wool sample are avoided.

The base plate 1 is provided with a notch 13 at the position pressed by the pressing bar 2. The wool sample is limited to move by the cooperation of the pressing strip 2 and the anti-slip pad 4 on the base plate 1, so that wool sample cutting is facilitated. The function of opening the notch 13 is that when the layering 2 is pressed down and touches the anti-slip pad 4, the anti-slip pad 4 can generate certain downward deformation at the position of the notch 13, which is helpful for the compaction of wool samples and the accurate pressing down of the layering 2. The non-slip mat 4 is preferably a silica gel mat.
In this embodiment, a stopper 12 is further provided on the edge of the upper surface of the base plate 1, and the stopper 12 is used to limit the movement of the anti-slip pad 4.
