The implementation process comprises the following steps:
the mask sheet 35 is placed on the supporting plate 37, the second motor 52 is started, the second output shaft 53 drives the spur gear 54 to rotate, so that the toothed plate 8, the second connecting plate 10, the fourth connecting plate 13, the third connecting plate 11, the first connecting plate 6 and the cylinder 24 are driven to move downwards, the first stretching strip 14 and the third stretching strip 29 penetrate through one mask belt 36 on the mask sheet 35, the second stretching strip 16 and the fourth stretching strip 30 penetrate through the other mask belt 36 on the other mask sheet 35, the lower end of the cylinder 24 abuts against the top wall of the mask sheet 35, the toothed plate 8 pushes the left side of the balance plate 43 downwards, the right side of the balance plate 43 is pushed upwards, and the upper end of the detection cylinder 40 abuts against the bottom wall of the mask belt 36.
Starting the first motor 3, the first output shaft 4 drives the top block 5 to rotate ninety degrees, because the top block 5 is oval, the top block 5 can push the first connecting plate 6 and the third connecting plate 11 to be away from each other, the first stretching strip 14 and the third stretching strip 29 can be gradually away from each other along the side wall of the first separation block 27, the second stretching strip 16 and the fourth stretching strip 30 can be gradually away from each other along the second separation block 28, so that stretching of the two mask belts 36 in different directions is performed, and thus, a stretching test is performed on the two mask belts 36, and the first pressure sensor 15 and the second pressure sensor 17 can respectively sense pressure data of the two mask belts 36.
The top block 5 rotates ninety degrees again, the first connecting plate 6 and the third connecting plate 11 approach each other under the elastic action of the first connecting plate 6 and the first elastic piece 7, the first stretching strip 14 and the third stretching strip 29 approach each other, and the second stretching strip 16 and the fourth stretching strip 30 approach each other, so that resetting is performed.
The principle is repeated by turning the top block 5 ninety degrees, and the two mask belts 36 are again subjected to tensile test, so that the mask belts 36 are repeatedly subjected to multiple tensile tests.
The external air supply system conveys waste gas to the flexible air pipe 26, the rigid air pipe 25 and the cylinder 24, the first output shaft 4 drives the push block 20 to rotate when rotating, the idler wheel 21 on the push block 20 pushes the inclined plane 19, so that the movable block 18 moves upwards, the movable block 18 drives the connecting rod 22 to move upwards, the elastic piece 23 is stretched upwards, when the push block 20 continues to rotate until the idler wheel 21 and the movable block 18 are separated from each other, the movable block 18 moves downwards rapidly under the action of the elastic force of the seventh elastic piece 181, the elastic piece 23 contracts downwards rapidly under the action of the elastic force of the elastic piece 181 and the elastic force of the seventh elastic piece 181, the waste gas in the cylinder 24 is compressed rapidly through the action of the elastic piece 23, and then is concentrated to be sprayed onto the mask piece 35 from the air outlet 241 of the bottom wall of the cylinder 24, so that the situation when external waste gas blows directly is simulated, the waste gas concentration in the mask piece 35 is detected through the waste gas sensor 41, and the quality of the mask piece 35 is judged.
After the detection, the second motor 52 is reversed to move the toothed plate 8, the second connecting plate 10, the fourth connecting plate 13, the third connecting plate 11, the first connecting plate 6 and the cylinder 24 upwards, the third magnetic block 9 adsorbs the first magnetic block 44 to move upwards, and the second magnetic block 45 adsorbs the fourth magnetic block 42 to move downwards, so that the whole system is reset.
When the first and second conditions occur, the processing module controls the extension of the piston rod on the cylinder 46:
in the first case, when the processing module detects that the value of the exhaust gas concentration of the exhaust gas sensor 41 is higher than or equal to the preset value, this means that the effect of blocking the exhaust gas by the mask sheet 35 is poor;
secondly, when the pressure data of the first pressure sensor 15 or the second pressure sensor 17 suddenly and rapidly decreases to zero at a certain moment, the mask belt 36 is broken, and the welding quality of the mask belt 36 is poor;
after the piston rod is extended, the sliding block 47 moves leftwards, and the first rotating rod 48 drives the supporting plate 37 to incline leftwards, so that the mask falls into the first recovery box 50.
When case three occurs, the processing module controls the piston rod on the cylinder 46 to shorten:
in the third case, when the processing module detects that the value of the exhaust gas concentration of the exhaust gas sensor 41 is lower than the preset value, and the pressure data of the first pressure sensor 15 or the second pressure sensor 17 is not suddenly and rapidly reduced to zero at a moment, it indicates that the mask sheet 35 and the mask belt 36 have better quality.
The sliding block 47 moves right after the piston rod is shortened, the first rotating rod 48 drives the supporting plate 37 to incline to the right, so that the mask falls into the second recovery box 51, and the mask sheets 35 with qualified quality and unqualified quality are classified and collected.
The invention can simultaneously carry out tensile test on the mask belt 36 and exhaust gas blocking effect test on the mask sheet 35, and can automatically control the mask sheet 35 to fall into different collecting boxes according to test results for classified collection, so that a user can rapidly distinguish masks with qualified quality and unqualified quality, the device is ingenious in design and strong in linkage, and rapid and convenient detection can be carried out in the mask production process.
