Slide track type leather specimen preparation device

Abstract

The invention discloses a slide track type leather specimen preparation device. The device comprises a substrate, wherein the substrate is provided with a rotating shaft, the rotating shaft is connected with a handgrip, and the handgrip rotates around the rotating shaft; the substrate is further provided with a slide rail structure, and the handgrip can slide up and down along the slide rail structure; a cutter is fixed on the handgrip, and the substrate is provided with a notch matched with the cutter; and a cutting edge is arranged at the circumference of the cutter, and the cutting edge defines a space for cutting a leather specimen. A point contact mode during leather specimen preparation based on the structure effectively solves the problem in the prior art that the preparation device needs to have a big volume and a large weight since a superhigh pressure is required for a rectangle perimeter type line contact mode of the cutter and leather in the process of preparing a 50*3 mm<2> bar-like leather specimen, and simultaneously solves the problem that a non-vertical component of a manually applied force in the operation process makes the cutting edge deviate from the notch and thus damages the cutting edge.

Description

technical field [0001] The invention belongs to the technical field of leather sample preparation and relates to a slideway type leather preparation device. Background technique [0002] Shrinkage temperature is an important physical parameter test item of leather. Specifically, it refers to the ambient temperature corresponding to the moment when the leather sample begins to shrink during the continuous and uniform heating process, which is its inherent characteristic. By accurately detecting its shrinkage temperature, it will directly reflect the kneading condition and heat-humidity stability of the leather, provide data support for the determination of processing materials and environmental conditions in the kneading process, and provide guidance for further processing and production of leather products or use selection . [0003] Although with the development of science and technology, there are many methods and devices for detecting shrinkage temperature, such as the m...

AI Technical Summary

Problems solved by technology

Through the point contact method where the plane of the knife edge and the plane of the leather sample intersect with an inclined line in space, and extend the instantaneous cutting operation into a continuous cutting process for a period of time, it effectively solves the problem of leather sample preparation in the prior art. The cutting tool and the leather are in rectangular perimeter line contact, which requires super-large pressure at the moment, which leads to the problem of large volume and heavy weight of the production device; more importantly, according to the principle of two points to determine a straight line, by adding slideways, it effectively solves the problem during the operation process. The non-perpendicular force applied by hand causes the knife edge to deviate from the slot and damage the knife edge.
