A tensile testing machine for testing the tensile degree of packaging bags

Abstract

The invention discloses a tensile testing machine for measuring the stretch degree of a packaging bag, comprising a base, 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 the interior of the base is provided with a support. The liquid tank, the end of the output shaft of the first motor is coaxially connected with a screw rod, the top of the base is fixedly connected with a positioning tube, and the end of the positioning tube is provided with a positioning piece, and the support is provided with a rotating roller, The end of the rotating roller is fixed with a positioning plate, and the outer wall of the rotating rod in the positioning plate is provided with a ratchet, the second motor is fixedly installed at the top center of the bracket, and the end of the output shaft of the second motor is connected through the connection. The shaft is fixedly connected with one end of the cross bar. The tensile testing machine for the tensile degree detection of the packaging bag is convenient for positioning and clamping on both sides of the packaging bag, improving the positioning and clamping stability of the packaging bag, and the rotary tensile degree 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...

Problems solved by technology

[0007] The object of the present invention is to provide a kind of tensile testing machine for testing the degree of stretching of packaging bags, to solve the above-mentioned background technology. The stability of the reinforcement is not high, and it is easy to cause the connection of the packaging bag to fall off during the stretching test of the packaging bag, resulting in operational errors in the final detection data, which affects the rapid detection of the stretching degree of the packaging bag. When the stretching operation of the packaging bag is performed, the The packaging is stretched on both sides in the same plane, and the tensile structure of the packaging bag is used for stretch detection, which makes the overall production volume of the device larger, resulting in a large space for the use and storage of the device, which is not conducive to the storage and transfer of the device. At the same time, the problem of inconvenience caused by the detection work
