Embodiment Construction

[0029] The present invention is described in further detail below in conjunction with accompanying drawing:

[0030] The invention provides a leather sample preparation device, such as figure 1 As shown, it includes the base plate 1, the base plate 1 is provided with a rotating shaft 2, a return spring is set on the rotating shaft 2, the rotating shaft 2 is connected with the handle 5, and the cross section of the handle 5 is "T" shaped to withstand the external force applied by the operator. And the handle 5 is retractable, or an extension rod that can save labor is added on the handle 5; elastic clips 3 are arranged on both sides of the rotating shaft 2, and the elastic clips 3 are connected with the fixed frame 4, and the fixed frame 4 is connected by a spring The pressure of the clamp secures the leather to be cut well, and the fixing frame 4 is a "U"-shaped frame structure.

[0031] Such as figure 2 As shown, the handle 5 is connected with a cutter 6, the base plate 1 ...

Abstract

The invention discloses a leather sample making device. The device comprises a base plate, wherein the base plate is connected with a handle through a rotary shaft provided with a reset spring, and elastic clamps are arranged on two sides of the rotary shaft and connected with a fixing frame; a cutter is arranged on the handle, cutting edges are formed on four side edges of the cutter, and a space as large as a leather sample is formed in each cutting edge; a notch matched with the cutter is formed in the base plate. The device works in a slope line intersection point contact manner and effectively solves the technical problems that a making device is large in size and weight due to the fact that a cutter and leather are in rectangular perimeter type linear contact and super-large pressure is required in the prior art when a leather sample with the size of 50*3 mm<2> is made once, the device is simple and manual operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of leather physical parameter testing, and relates to a leather sample preparation device, in particular to a leather sample preparation device for testing leather physical parameters. Background technique [0002] Shrinkage temperature is an important physical parameter test item of leather. Specifically, it refers to the corresponding ambient temperature when the leather sample starts to shrink in the process of continuous and uniform heating. It is an inherent characteristic of leather itself. By accurately detecting its shrinkage temperature, it can directly reflect the kneading condition and thermal-moisture 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. The test shrinkage temperature adopts the QB / T2706-2005 ...
