Technical Field
[0001] The utility model belongs to the technical field of chemical fiber quality detection tools, and particularly relates to a slicer for a chemical fiber cross-section observation slice. Background Art
[0002] In chemical fiber production, the observation of the fiber cross-section is crucial for production stability and product quality improvement. At present, in the production process of chemical fibers, many cross-section observation slices need to be made. By observing the cross-section to determine whether the quality of the fibers meets the standards is an essential step in the chemical fiber inspection process. Currently, the preparation of cross-section observation slices usually involves wrapping the polyester fibers to be detected in viscose fibers, twisting them into a bundle, then passing them through the small holes in the thin sheet tool, and finally using a blade to cut off the excess fibers on both sides of the thin sheet tool. The fiber cross-section in the small holes of the thin sheet tool is observed under a microscope. Manually holding the blade for cutting is likely to cut the hand, posing a certain safety hazard. Content of the Utility Model

[0005] A slicer for a chemical fiber cross-section observation slice, characterized in that: it includes a substrate, a thin sheet, a handle and a spatula. One side of the handle is slidably connected to the substrate, and the other side is connected to the spatula. The spatula fits on the upper end surface of the substrate and makes a reciprocating linear motion. The thin sheet is movably embedded in the positioning groove on the upper end surface of the substrate, and the upper end surface of the thin sheet is flush with the upper end surface of the substrate. The positioning groove is located on the path of the linear motion of the spatula, and at least two uniformly spaced positioning holes are provided on the thin sheet.
[0006] Preferably, a slider is connected to the handle, and the slider is slidably connected to the slide rail provided on the substrate.
[0007] Preferably, the handle is inclined and its lower end is connected to the slider.
[0008] Preferably, the end of the handle is rotatably connected to the connecting shaft provided on the slider, and a support spring is also connected between the slider and the handle. The support spring is located on one side of the connecting shaft.
[0009] Preferably, the handle is of a U-shaped structure.
[0010] Preferably, the positioning groove is a stepped through hole, including an upper hole body and a lower hole body. The aperture of the upper hole body is larger than that of the lower hole body, and the shape and size of the upper hole body match those of the thin sheet.
[0011] Preferably, the positioning hole is in the shape of a truncated cone.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] (1) In the present utility model, the chemical fiber to be detected is fixed in the positioning hole on the thin sheet, and then the thin sheet is embedded in the positioning groove of the substrate.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0023] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0024] In the present utility model, unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0025] As Figure 1 , Figure 3 and Figure 4 shown, a slicer for a chemical fiber cross-section observation slice includes a substrate 1, a thin slice 2, a handle 3 and a spatula 4. One side of the handle is slidably connected to the substrate, and the other side is connected to the spatula. The spatula fits on the upper end surface of the substrate and moves in a reciprocating straight line. The thin slice is movably embedded in the positioning groove 5 on the upper end surface of the substrate. Combining Figure 2 shown, the positioning groove is a stepped through hole, including an upper hole body 501 and a lower hole body 502. The aperture of the upper hole body is larger than that of the lower hole body, and the shape and size of the upper hole body match the shape and size of the thin slice. When the thin slice is embedded in the upper hole body, the lower end surface of the thin slice fits on the end of the lower hole body, and the upper end surface of the thin slice is flush with the upper end surface of the substrate. The setting of the through hole of the positioning groove facilitates the end of the chemical fiber to pass through the substrate. The positioning groove is located on the path of the straight-line movement of the spatula. At least two positioning holes 6 are evenly spaced on the thin slice. The positioning holes on the thin slice are used to insert the chemical fibers to be detected and fix the corresponding chemical fibers with viscose fibers. Combining Figure 5 shown, the positioning hole is a frustum of a cone structure, that is, one end of the aperture is large and the other end is small, which is convenient for strengthening the firmness of the chemical fiber. After the thin slice is embedded in the positioning groove, push the handle to slide linearly along the substrate, so that the spatula slides along the upper end surface of the substrate. When the spatula passes by the thin slice, the chemical fiber exposed outside the positioning hole of the thin slice is cut off, eliminating the trouble of the operator directly holding the cutter by hand and improving safety. In this embodiment, both the substrate and the thin slice are made of metal, which are firm and durable. The spatula includes a tool holder and a blade. The blade is assembled on the tool holder by screws or bolts, and the two can be freely disassembled and assembled, which is convenient for replacing the blade. The specific structure will not be elaborated again here.
[0026] As Figure 1 andFigure 3 As shown, the handle has a U-shaped structure, with one end connected to the slider and the other end connected to the cutting blade. To improve the sliding stability between the handle and the substrate, a slider 7 is connected to the handle, and the slider is slidably connected to a slide rail 8 provided on the substrate. The handle is inclined and its lower end is connected to the slider. This structural design meets the requirements of ergonomics and is convenient for pushing the handle to slide. The end of the handle is rotatably connected to a connecting shaft 9 provided on the slider. The end of the handle is sleeved on the connecting shaft. A support spring 10 is also connected between the slider and the handle. The support spring is located on one side of the connecting shaft, which can effectively support the handle and is also convenient for adjusting the cutting angle and replacing the blade.
[0027] The usage method of the present utility model is as follows:
[0028] (1) First, wrap the chemical fiber to be inspected with viscose fiber and twist it into a wrapped tow;
[0029] (2) Pass the wrapped tow through the positioning holes 6 in the thin sheet 2. Each positioning hole 6 passes through a different tow; the tow is inserted from the end with a larger aperture and exits from the end with a smaller aperture, and then the tow is tightened. The viscose fiber solidifies to fix the tow;
[0030] (3) Insert the thin sheet 2 with the tows to be inspected passed through into the upper hole body 501 of the positioning groove 5, with the end of the positioning hole 6 having a larger aperture facing upward to prevent the tow from falling off during the cutting process. Push the handle 3 to slide along the substrate 1, and the cutting blade 4 cuts the fiber on one side of the thin sheet;
[0031] (4) Take out the thin sheet from the positioning groove 5 and turn it over to the other side, then insert it into the positioning groove 5 again. Push the handle 3 to slide along the substrate 1, and the cutting blade 4 cuts the fiber on the other side of the thin sheet 2 to obtain a chemical fiber cross-section observation sheet;
[0032] (5) Place the chemical fiber cross-section observation sheet under a microscope for observation and record the fiber cross-section conditions.
[0033] The above shows and describes the basic principles, main features and advantages of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
