Abstract

The invention discloses a tensile testing machine for detecting the tensile strength of a packaging bag. The tensile testing machine for detecting the tensile strength of the packaging bag comprises abase, a first motor, a pressure sensor, a second motor and a torque sensor. A bracket is fixedly connected to the top of the base, and a liquid groove is formed in the base. A screw rod is coaxiallyconnected to the end of an output shaft of the first motor, a positioning tube is fixedly connected to the top of the base, and a positioning member is arranged at the end of the positioning tube. A rotating roller is arranged on the bracket, a positioning disk is fixed to the end of the rotating roller, and a ratchet is arranged on the outer wall of a rotating rod in the positioning disk. The second motor is fixedly installed at the center of the top of the bracket, and the end of an output shaft of the second motor is fixedly connected with one end of a cross rod through a coupler. Accordingto the tensile testing machine for detecting the tensile strength of the packaging bag, two sides of the packaging bag can be conveniently positioned and clamped, the positioning and clamping stability of the packaging bag is improved, and rotating type tensile strength detection reduces the overall size of the device.

Description

technical field

[0001] The invention relates to the technical field of packaging bag testing, in particular to a tensile testing machine for testing the stretching degree of packaging bags. Background technique

[0002] The packaging bag is a packaging and isolation tool before transporting and storing products and equipment. Through the use of packaging bags, the products and equipment can be effectively isolated from the external environment, and the products and equipment can be stored in a unified manner, avoiding the process of transshipment and storage. The loss of the loss and the damage of the nature of the use due to the influence of the external environment, resulting in the shortening of its service life. After the production and processing of the packaging bag, in order to ensure that the use of the packaging bag meets the quality requirements of its application, it is necessary to stretch the packaging bag mechanically. Inspection, knowing the average stretching...
