[0004] Basalt fiber-related experiments often require basalt fibers to be cut, but the existing fiber cutting equipment in the laboratory is large and heavy, making it difficult to operate. Sometimes operators are required to use a knife to perform secondary cutting on the basalt fibers to meet the experimenter's requirements. Utility Model Content

[0005] The utility model aims to provide a basalt fiber cutting device for laboratory to solve the problems that the existing fiber cutting equipment in the laboratory is difficult to operate and the cutting results are not up to standard.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a basalt fiber cutting device for laboratory use, comprising a base plate, a baffle plate and a guide roller are arranged on the base plate, a gear roller fixing assembly is arranged on the baffle plate, the gear roller fixing assembly is positioned and fixed by a gear roller fixing assembly positioning screw, the gear roller fixing assembly has two ends passing through its interior, a gear roller rocker is installed at one end of the gear roller, an auxiliary rotation accessory is connected to the side of the base plate through a groove-type interface, a rotatable knife groove is connected through the auxiliary rotation accessory, the auxiliary rotation accessories are connected and fixed by auxiliary rotation fixing screws, a cutter is fixed to the rotatable knife groove through a cutter fixing screw, a knife handle is installed on the cutter, and the knife handle is installed on the side opposite to the cutter fixing screw.

[0007] In the above-mentioned laboratory basalt fiber cutting device, the basalt fiber is guided toward the center of the device by a guide roller, which is beneficial to the stable cutting and consistent length of the basalt fiber short segment during cutting. According to the fiber diameter, the gap between the bottom plate and the toothed roller is adjusted by a toothed roller fixing assembly, and the toothed roller fixing assembly is fixed and positioned by a positioning screw of the toothed roller fixing assembly. The toothed roller is driven to rotate by shaking a toothed roller rocker. The friction between the basalt fiber and the toothed roller, and between the basalt fiber and the bottom plate is utilized to make the toothed roller drive the basalt fiber forward. The roller teeth evenly distributed on the toothed roller are beneficial to the user to control the length of the basalt fiber short segment, so as to obtain the basalt fiber short segment that meets the requirements. The auxiliary rotating accessory is utilized to rotate the rotatable knife groove around the connection point between the auxiliary rotating accessory and the bottom plate and the rotatable knife groove and the connection point between the auxiliary rotating accessories, and the angle between the plane where the cutting knife is located and the basalt fiber is adjusted, thereby adjusting the cross section of the basalt fiber short segment, cutting out the basalt fiber short segment that meets the relevant experimental requirements, and improving the application scope of the cutting device.

[0008] As a further improvement of the present application, the gear roller fixing assembly is located on the baffles on both sides of one end of the base plate, and the positioning screws of the gear roller fixing assembly are installed on the outside of the gear roller fixing assembly, passing through the gear roller fixing assembly to squeeze the baffle to achieve the purpose of positioning and fixing.

[0009] As a further improvement of the present application, both ends of the gear roller pass through and are installed inside the gear roller fixing assembly, and a gear roller rocker is installed at one end of the gear roller, and the gear roller is rotated by shaking the gear roller rocker.

[0010] As another improvement of the present application, the auxiliary rotation accessory is movably installed between the base plate and the rotatable knife slot, and the auxiliary rotation accessories are connected by auxiliary rotation fixing screws, so that the rotatable knife slot can rotate around the connection points between the auxiliary rotation accessory and the base plate and the rotatable knife slot and the connection points between the auxiliary rotation accessories.

[0011] As another improvement of the present application, two guide rollers are installed on the bottom plate, the lower guide roller is located at the end away from the baffle, and the higher guide roller and the lower guide roller are close to the baffle. By setting the height difference between the guide rollers, it is helpful to promote the basalt fibers to move closer to the center.

[0012] In summary, this application has the following beneficial effects:

[0013] 1. The length of the short section of basalt fiber is adjustable; the toothed roller uses friction to drive the basalt fiber forward, and uses the uniform roller teeth on the toothed roller to regulate the length of each short section of basalt fiber, thereby achieving the adjustment of the length of each short section of basalt fiber.

[0014] 2. Stable operation and consistent short segment length; Setting the height difference between the two guide rollers is conducive to pushing the basalt fiber to the center, so that when the basalt fiber reaches the tooth roller, it is perpendicular to the horizontal line where the tooth roller is located, which is convenient for the stable cutting operation and helps to keep the short segment length of the basalt fiber consistent.

[0015] 3. The cross section is adjustable to meet special requirements; the rotatable knife groove can rotate around the connection points between the auxiliary rotating accessories and the bottom plate and the rotatable knife groove and the connection points between the auxiliary rotating accessories, so that the angle between the plane where the cutting knife is located and the basalt fiber can be adjusted, and then the cross section produced by cutting can be adjusted to meet the special requirements of some experiments.
