Adjustable fiber cutting-off and weighing device

Abstract

The invention discloses an adjustable fiber cutting-off and weighing device. The adjustable fiber cutting-off and weighing device comprises a clamping plate bracket part arranged at the bottom, wherein a shearing part, limiting parts, a notch adjusting part and a fiber bundle tension control part are arranged on the clamping plate bracket part; an electronic balance is arranged below the clampingplate bracket part; the clamping plate bracket part consists of a bracket body and a supporting plate; the bracket body is provided with a notch distance adjusting part; the notch distance adjusting part is a scaleplate with scales; two L-shaped clamping plates are symmetrically arranged in the middle of the bracket body; the fiber bundle tension control part is arranged at the tail end of one side of the supporting plate; each limiting part is arranged on the corresponding L-shaped clamping plate and consists of a limiting groove and a limiting clamp slot; and the shearing part is arranged between the two L-shaped clamping plates. The adjustable fiber cutting-off and weighing device is used for cutting off and weighing fiber materials when measuring linear densities of fibers by a middle-section cutting-off method or measuring lengths of chemical fibers by a cutting-off and weighing method, and the size of a fracture of a cutting-off device for fibers is adjustable to adapt to difference.

Description

technical field [0001] The invention belongs to the technical field of fiber detection, and in particular relates to an adjustable fiber cutting and weighing device. Background technique [0002] At present, there are some problems in the actual use of the cutters used in the measurement of fiber fineness by the mid-cut weighing method and the measurement of the length of chemical fibers by the cut-off weighing method: the cutter suitable for cutting cotton fibers is not suitable for cutting other fibers such as Y171-10 type The cutting distance is 10mm, etc., because there are differences in the length distribution of different types of fibers, and different types of fibers have their own suitable cutting lengths. There is no fiber cutter in the prior art that can meet the needs of cutting different types of fibers. Second, there is no limit mechanism at the holding port, and the relevant fiber cutting device disclosed in the prior art has no fiber restraint control mechan...

Problems solved by technology

[0002] At present, there are some problems in the actual use of the cutters used in the measurement of fiber fineness by the mid-cut weighing method and the measurement of the length of chemical fibers by the cut-off weighing method: the cutter suitable for cutting cotton fibers is not suitable for cutting other fibers such as Y171-10 type The cutting distance is 10mm, etc., because there are differences in the length distribution of different types of fibers, and different types of fibers have their own suitable cutting lengths

There is no fiber cutter in the prior art that can meet the needs of cutting different types of fibers

Second, there is no limit mechanism at the holding port, and the relevant fiber cutting device disclosed in the prior art has no fiber restraint control mechanism, and it is easy to tilt when placing the fiber bundle that has been arranged, so that the length between the fibers in the fiber section cut by the knife edge exists. Big difference influences the accuracy of measurement; The 3rd, the edge of the fiber midsection cutter of prior art is that rectangular blade and concave groove cooperate to cut off fiber or hollow circular double-edged stainless steel blade, these several edge sharpness and sharpness Due to the problem of structural design, the retention is not ideal. There are often several fibers that have not been cut, and the blade is easy to blunt. At the same time, the shape of the blade increases the difficulty of grinding and restoring the blade. Once the blade is blunt, the device will be almost unusable.

Fourth, the fiber cutting device given in the prior art cannot weigh the cut fibers in time, and the possibility of dropping the fibers during the process of picking up the cut fibers for weighing is very high, thus causing serious measurement errors; , the fiber cutting device given in the prior art can be applied to fibers, fiber bundles and fiber webs, but in practice, there are large differences in the longitudinal dimensions of fiber webs, fibers and fiber bundles, and the scope of application of the equipment must be increased, which increases Therefore, the fiber cutting device for cutting fiber webs should be different from the design that can cut fibers and fiber bundles. The structure of cutting fibers or fiber bundles should be simple, small in size, and easy to adjust. Convenient and fast weighing
