A multi-purpose test filter paper cutting device and cutting method

Abstract

The invention discloses a multipurpose testing filter paper cutting device and method. The device comprises a circular top plate, a horizontal plate, a circular bottom plate and two vertical rods. Thecircular top plate, the horizontal plate and the circular bottom plate are sequentially arranged in parallel from top to bottom. The two vertical rods are connected to the left side and the right side between the circular top plate and the circular bottom plate, the bottom of the circular top plate is provided with a jack, the jack is located between the circular top plate and the horizontal plate, the portion, facing the horizontal plate, of the jack is provided with a telescopic rod, the end of the telescopic rod of the jack is fixedly connected with the top of the horizontal plate, the bottom of the horizontal plate is connected with a cylindrical iron block through a spring, the bottom of the horizontal plate is provided with a plurality of annular blades, and filter paper pressing nuts are in threaded connection with the lower portions of the vertical rods. The cutting device has the advantages of being simple and novel in structure, stable in cutting quality, easy and convenientto operate in a cutting mode, and the like, and the scientific research level of geotechnical tests is improved; and the cutting method is easy and convenient to operate and controllable, the cut filter paper finished product is quite high in quality, and filter paper raw materials are saved.

Description

technical field [0001] The invention relates to the technical field of filter paper preparation for geotechnical tests, in particular to a filter paper cutting device and a cutting method for multipurpose tests. Background technique [0002] A large amount of circular filter paper is required in the geotechnical test. The diameter of the filter paper is the same as that of the soil sample used in the test, which is conducive to the drainage of the soil sample and can also prevent the soil sample particles from entering the instrument. The relevant test specifications also stipulate the use of filter paper, which is essential , and the same piece of filter paper can only be used once and cannot be reused. How to efficiently prepare filter paper for testing is of great significance. Existing filter paper cutting tools are mainly scissors, relying on manual cutting of filter paper, there is a problem of time-consuming, laborious and irregular, at the same time, the method is re...

AI Technical Summary

Problems solved by technology

[0003] In view of the fact that the cutting of existing test filter paper mainly relies on scissors, which has the technical problem of time-consuming, laborious and irregular, the purpose of the present invention is to provide a multi-purpose test filter paper cutting device and cutting method. The cutting device has a simple and novel structure, low cost The advantages of controllability, energy saving and environmental protection, stable cutting quality, high degree of cutting standardization, simple and controllable cutting operation, etc., have improved the scientific research level of geotechnical testing
