[0028] The woven bag clamped between the two connecting plates 4 is stretched straight, and the mounting plate 62 is pushed down by starting the cylinder 67, so that the pressure plate 64 is pressed on the top of the woven bag and moves downward to detect the plastic woven bag. The pressure is reflected by the pressure sensor 63. After the detection is completed, the telescopic end of the cylinder 67 is controlled to contract, and the pressure plate 64 is driven to rise and reset quickly under the action of the elastic force of the first spring 65.

[0029] The woven bag clamped between the two connecting plates 4 is stretched straight, the electromagnet 74 is powered off to make it lose its magnetic force, and the friction plate 72 is driven to slide up and contact with the bottom of the woven bag through the rebound of the second spring 75. The turntable 81 is driven to rotate by starting the second motor 91. The movable seat 7 is driven to slide horizontally left and right on the top of the testing platform 1 under the action of the extrusion slider 82, the rectangular frame 8 and the sliding block 76. The wear resistance of the woven bag is tested by the friction plate 72.
