The piercing strength of the cardboard refers to the work done through the cardboard with a pyramid of a certain shape. That includes the work required to start the puncture and tear and bend the cardboard into a hole. Expressed in Joules (J). This method can be applied to various types of cardboard, such as box cardboard, corrugated cardboard and so on. DRK104 electronic cardboard puncture strength tester is a special instrument for measuring the puncture resistance (ie puncture strength) of corrugated cardboard. Performance Characteristics: The DRK104 electronic cardboard puncture strength tester has the characteristics of fast clamping of the sample, automatic reset of the operating handle, and reliable safety protection. It has microcomputer control technology and LCD Chinese display; it has the function of statistical processing of test data and can be printed out. ◆1 Full computer control technology, open structure, high automation program, simple and convenient operation, safe and reliable; ◆2 Fully automatic measurement, intelligent judgment function, the operating system displays the measurement results in real time; ◆3 Automatic measurement, statistics, and print test results, and have data storage function; ◆4 Chinese graphic menu display operation interface, easy to use; ◆5 Thermal high-speed micro printer, high-speed printing, low noise, no ink and ribbon, easy to use, low failure rate; ◆6 Modern design concept of electromechanical integration, compact structure, beautiful appearance and easy maintenance. Applications: It has a wide range of applications and is an indispensable common instrument for enterprises and departments such as cardboard and carton production, scientific research and commodity inspection. Working Principle: The DRK104 electronic cardboard piercing strength tester is composed of a pendulum system sample holding device, a pointer dial pyramid (piercing head) operating system and other parts. According to the functional principle, the instrument installs a triangular prism pyramid designed and produced according to the standard geometry on a pendulum with a special shape, and uses the energy of the pendulum to make the triangular pyramid penetrate the sample. Instrument Structure: (1) Base and stand. (2) Pendulum device: It is composed of pendulum body, pendulum shaft, piercing head and heavy mound. (3) The test part is composed of pointer, pointer shaft and dial. (4) Specimen clamping device: composed of upper and lower pressing plates and clamping springs. (5) The release body is composed of a pillar and a release body handle. Technical Standard: The DRK104 electronic cardboard piercing strength tester meets the following standards: The product is designed with reference to ISO3036 (cardboard-determination of piercing strength) and GB2679·7-2005 "Testing method for cardboard piercing strength". It has fast compression and automatic handle operation. Reliable features of reset and safety protection. Product parameters:
