Example two

A product performance detection method for water-based PU synthetic leather comprises the following steps:

the method comprises the following steps: inserting two ends of a leather material to be detected 509 into locking channels 508 of the two mounting plates 507 respectively, and fixing the leather material to be detected 509 and the mounting plates 507 through a plurality of bolts after the leather material to be detected 509 is in a horizontal tensioning state;

step two: the driving motor 403 is started to drive the rotating rod 401 to rotate, the rotating rod 401 drives the cam 404 to synchronously rotate when rotating, the rotating cam 404 is matched with the first spring 416 to enable the pressing plate 406 to do up-and-down reciprocating motion, when the pressing plate 406 moves downwards, the pressing roller 413 is in contact with the material to be detected 509 and presses the material to be detected 509 downwards, the material to be detected 509 between the two mounting rollers 809 is sunken downwards in a V shape, and the material to be detected 509 is pressed and bent;

step three: the two driving motors 813 are started to drive the missing gear 812 to rotate, the missing gear 812 is in contact with the rack 811 to drive the transverse moving plate 810 to move towards the direction close to the vertical plate 801, and when the missing gear 812 is separated from the rack 811, the reaction force of the third spring 806 pushes the sliding sleeve 805 to reset, so that the two mounting rollers 809 synchronously reciprocate in the horizontal direction, and the bending position of the material 509 to be detected is changed continuously;

step four: after the press bending is completed, the leather 509 to be inspected is detached from between the two mounting plates 507, images of two surfaces of the leather 509 to be inspected are captured, the crease condition in the images is analyzed, and the folding resistance of the leather 509 to be inspected is judged.

When the product performance detection equipment for the water-based PU synthetic leather is used, two ends of a leather material to be detected 509 are respectively inserted into locking channels 508 of two mounting plates 507, and after the leather material to be detected 509 is in a horizontal tensioning state, the leather material to be detected 509 and the mounting plates 507 are fixed through a plurality of bolts; the driving motor 403 is started to drive the rotating rod 401 to rotate, the rotating rod 401 drives the cam 404 to synchronously rotate when rotating, the rotating cam 404 is matched with the first spring 416 to enable the pressing plate 406 to do up-and-down reciprocating motion, when the pressing plate 406 moves downwards, the pressing roller 413 is in contact with the material to be detected 509 and presses the material to be detected 509 downwards, the material to be detected 509 between the two mounting rollers 809 is sunken downwards in a V shape, and the material to be detected 509 is pressed and bent; two driving motors 813 are started to drive the lacking gear 812 to rotate, the lacking gear 812 rotates to be intermittently contacted with the rack 811, when the lacking gear 812 is contacted with the rack 811, the transmission action of the lacking gear 812 and the rack 811 drives the sliding sleeve 805 to move on the sliding rod 803 towards the direction close to the vertical plate 801, when the lacking gear 812 is separated from the rack 811, the sliding sleeve 805 resets under the reaction force of the third spring 806, so that the sliding sleeve 805 slides on the sliding rod 803 towards the direction far away from the vertical plate 801, the mounting rollers 809 and the sliding sleeve 805 synchronously move, so that the two mounting rollers 809 synchronously reciprocate in the horizontal direction, when the mounting rollers 809 perform reciprocating transverse movement and the pressing rollers 413 press the surface, the contact position of the mounting rollers 809 and the leather 509 to be detected is a bending position, therefore, the two mounting rollers 809 perform continuous opening and closing movement to match the pressing rollers 413 to perform pressing bending on the leather 509 to be detected at a high frequency, a small-area concentrated crease is formed on the top surface of the leather material 509 to be detected, a large-range multi-area dispersive crease is formed on the bottom surface of the leather material 509 to be detected, and the folding resistance of the leather material 509 to be detected is judged by comprehensively analyzing the crease conditions of the top surface and the bottom surface of the leather material 509 to be detected.
