Abstract
Description
Technical Field
[0001] This utility model relates to the field of sofa fabric testing technology, and in particular to a sofa fabric tear resistance testing device. Background Technology
[0002] When producing sofa fabrics, it is necessary to test their tear resistance. Existing testing devices can only perform lateral or longitudinal tensile tests, limiting the testing direction. Furthermore, since some sofas are used outdoors in courtyards, they are easily exposed to sunlight. Ultraviolet rays and the high temperatures generated by sunlight affect the tear resistance of sofa fabrics. However, existing testing devices can only perform tests at room temperature and cannot simulate the effects of high temperatures and ultraviolet rays from sunlight. Therefore, there is an urgent need to develop a sofa fabric tear resistance testing device that is convenient for testing the tear resistance of fabrics, utilizes a rotation adjustment mechanism to test tear resistance in different directions, and can use xenon lamps and heaters to simulate ultraviolet rays and high temperatures to test the tear resistance of fabrics under ultraviolet and high-temperature environments. This device would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

The transparent observation door is hinged to the front of the test chamber. The tensile sensor is fixedly installed inside the test chamber. The rotation adjustment mechanism is mounted on the test chamber, and the electric telescopic rod is fixedly mounted on the rotation adjustment mechanism. Two clamping mechanisms are arranged vertically opposite each other; one clamping mechanism is fixedly connected to the tensile sensor, and the other clamping mechanism is connected to the electric telescopic rod. The telescopic end is fixedly connected. A temperature sensor is installed on one side of the tension sensor inside the test box. The heater and xenon lamp are both fixedly installed inside the test box. The rotation adjustment mechanism includes: a drive motor, a first gear, a second gear, a transmission shaft, and a turntable. The drive motor is fixed to the test box. A first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it. The second gear is fixed to the transmission shaft. The transmission shaft is rotatably connected to the test box. The turntable is fixed to the transmission shaft. The electric telescopic rod is fixedly installed on the turntable.

[0007] Preferably, a PLC controller is installed on the outside of the test box, and the tension sensor, electric telescopic rod, drive motor, temperature sensor, heater and xenon lamp are electrically connected to the PLC controller.
[0008] The beneficial effects of this utility model are as follows: When using this sofa fabric tear resistance testing device, the upper and lower ends of the fabric are first clamped into the clamping mechanism, then the transparent observation door is closed. An electric telescopic rod drives one of the clamping mechanisms to pull the fabric up and down. Simultaneously, a tension sensor transmits the tension to the PLC controller for display. Furthermore, a drive motor drives the first gear, the second gear, the transmission shaft, and the turntable to rotate. The turntable drives the electric telescopic rod to rotate, thereby adjusting the orientation of the electric telescopic rod and thus the pulling direction, to test the tear resistance of the fabric in different directions.

It can also use a xenon lamp and heater to simulate ultraviolet radiation and high-temperature environments to test the tear resistance of fabrics under ultraviolet radiation and high-temperature environments.
