As shown in fig. 1 to 3, the present invention provides a testing device for a gauze, including a first bracket 100, a lifting mechanism and a second bracket, wherein the first bracket 100 is used for supporting a gauze 102; the lifting mechanism is used for driving the weight 104 to switch between a contact position and a separation position, wherein the weight 104 compresses the gauze 102 at the contact position, and the weight 104 is far away from the gauze 102 at the separation position; the second bracket is used for mounting the lifting mechanism.
The utility model provides a testing arrangement of gauze drives weight 104 through hoist mechanism and switches between the position of contact gauze 102 and the position that separates with gauze 102, can realize the test to gauze 102 performance. Through setting up hoist mechanism, saved operating personnel and placed the step of weight 104, when not needing the test, can hang weight 104 from gauze 102, and then avoided gauze 102 damaged back, weight 104 drops and injures operating personnel by a crashing object. In addition, through setting up hoist mechanism, can also promote the precision of placing weight 104, guaranteed the accuracy to gauze 102 capability test.
Specifically, the first bracket 100 is supported at both ends of the screen 102 so that the screen 102 can be kept away from and level with the ground. The number of the first brackets 100 is two, and the two first brackets 100 are respectively supported on the left and right sides of the gauze 102, for example, the two first brackets 100 may be respectively supported on the two sides of the gauze 102 with relatively narrow width.
The lifting mechanism is used for lifting or lowering the weight 104, and when the weight 104 is lowered by the lifting mechanism, the weight 104 can be tightly pressed on the gauze 102 to test the performance of the gauze 102; when the lifting mechanism lifts the weight 104, the weight 104 can be moved away from the screen 102. Thus, when the gauze 102 needs to be tested, the weight 104 can be lowered through the lifting mechanism, and the weight 104 is pressed on the gauze 102. After the test is completed, the weight 104 can be lifted by the lifting mechanism to lift the weight 104 off the screen 102. More importantly, because the lifting mechanism is used for placing the weight 104 or lifting the weight 104, the process of placing and taking out the weight 104 by an operator is omitted, and the steps of testing the gauze 102 can be effectively simplified. In addition, if in the test process, gauze 102 is damaged, because the existence of hoist mechanism, weight 104 also can not drop, just so can avoid weight 104 to pound operating personnel.

The other ends of the weights 104 and the sling 110 are detachably connected, so that when the weight of the weight 104 needs to be increased, a plurality of weights 104 can be directly hung on the sling 110.
The specific working process of the implementation mode is as follows:
first, a screen 102 is placed on a first holder 100;
secondly, the part of the sling 110 is retracted by the motor 106;
thirdly, selecting a proper weight 104 and hanging the weight 104 on the sling 110;
again, part of the sling 110 is released by the motor 106 so that the weight 104 is pressed against the gauze 102;
after the test is completed, part of the sling 110 is retracted by the motor 106 to move the weight 104 away from the screen 102.
The implementation mode two is as follows:
as shown in fig. 3, the lifting mechanism includes a motor 106, a pulley 112, and a sling 110. The motor 106 is mounted to the second bracket; the sling 110 is wound around the pulley 112, and two ends of the sling 110 are respectively connected with the motor 106 and the weight 104.
