[0024] A method for detecting the air permeability of cowhide leather comprises the following steps: First, water is injected into the detection bucket 7, and then the cowhide leather strip to be tested is placed on the conveyor belt 3 and transported to the detection bucket 7 through the support component 6. Then, the air-filling barrel 8 is started to move downward to seal and extrude the cowhide leather strip.

The second limiting column 410 is moved by the moving frame 412 to flip the mounting plate 411, so that the mounting plate 411 drives the air-filling barrel 8 and the detection bucket 7 to flip in position. Then, the air pump 9 is started to blow air into the detection bucket 7 through the air-filling barrel 8, and the bubbles in the detection bucket 7 are recorded and detected by the detector 10.

[0025] The working principle of the present invention is as follows: when using the device, first fill the detection bucket 7 with water, then place the cowhide leather strips to be detected on the conveyor belt 3 respectively, so that the conveyor belt 3 moves toward the detection bucket 7 through the limit bar 68, so that the limit bar 68 squeezes the cowhide leather under the drive of the conveyor belt 3, and at the same time, the cowhide leather squeezes the baffle 65, so that the baffle 65 drives the slide bar 63 to slide on the fixed plate 61, and at the same time, the slide bar 63 drives the connecting plate 62 to squeeze the spring 64, so that the spring 64 is in a compressed state, and then the cowhide leather falls on the slide bar 63, and at the same time, the slide bar 63 drives the cowhide leather to move to the top of the detection bucket 7, and then the electric telescopic plate on the detection bucket 7 is started to drive the inflatable bucket 8 to move toward the detection bucket 7, and then the cowhide leather is sealed and clamped, and then the motor 4 is started. 17, so that the output end of the motor 417 drives one of the pulleys 419 to rotate, and at the same time, one of the pulleys 419 drives the other pulley 419 to rotate synchronously through the belt 418, and at the same time, the rotating shaft of the pulley 419 drives the reciprocating screw 42 to rotate synchronously in the rectangular through hole 41, and at the same time, the reciprocating screw 42 drives the reciprocating block 44 to slide on the balance bar 43, and at the same time, the reciprocating block 44 drives the moving frame 412 to move upward through the connecting shaft, and at the same time, the mounting plate 411 drives the detection bucket 7 and the inflatable bucket 8 to move upward, and at the same time, the detection bucket 7 moves upward from the storage groove 11, so that the detection bucket 7 separates the cowhide from the baffle 65, and at the same time, the elastic reset force of the spring 64 drives the slide bar 63 to slide on the fixed plate 61, and at the same time, the baffle 65 elastic reset, at the same time, the connecting shaft of the mounting plate 411 drives the arc block 49 and the second limiting column 410 to move toward the toggle plate 415, and at the same time, the toggle plate 415 squeezes the second limiting column 410. When the reciprocating block 44 continues to move upward, the reverse extrusion force received by the second limiting column 410 drives the arc block 49 to flip between the two toggle plates 415, breaking away from the obstruction and extrusion of the toggle plate 415, and at the same time, the arc block 49 drives the connecting shaft of the mounting plate 411 to rotate on the reciprocating block 44, and at the same time, the reciprocating block 44 drives the detection bucket 7 and the inflation bucket 8 to flip, so that the detection bucket 7 is above the inflation bucket 8, and at the same time, the connecting shaft of the mounting plate 411 drives the rotating rod 46 to rotate on the reciprocating block 44 to the other first limiting column 45, and rotates The rotating rod 46 stretches the elastic band 48 during the rotation process, and at the same time, the mounting plate 411 drives the convex column 54 to slide in the concave groove 55 to the rotating groove 57 and then flips over. After the flip is completed, the convex column 54 moves toward the rotating groove 57 under the guidance of the first guide plate 58, and at the same time, the reverse force of the first guide plate 58 drives the convex column 54 to drive the slider 53 to slide in the sliding groove 51, and at the same time, the slider 53 slides on the limiting rod 52, and then the convex column 54 moves into the rotating groove 57 under the action of the first guide plate 58, and then moves into the concave groove 55 under the guidance of the second guide plate 56, and at the same time, the reciprocating screw rod 42 drives the reciprocating block 44 to move downward. When the second limiting column 410 contacts the inclined surface of the triangular plate 413,The second limiting column 410 squeezes the triangular plate 413, causing the triangular plate 413 to drive the moving frame 412 to move in the moving groove 416, and at the same time, the moving frame 412 slides on the guide rod 414, and at the same time, the moving frame 412 drives the stabilizing frame 59 to slide on the reinforcing plate 511 through the sliding roller 510, and at the same time, the moving frame 412 drives the convex column 54 and the slider 53 to slide in the sliding groove 51 through the concave groove 55, so that the moving frame 412 drives the toggle plate 415 to move to a position close to the second limiting column 410, so as to prepare for the next flip. During the flip and descent process, the air pump 9 is started to inflate the cowhide through the air barrel 8, so that the gas penetrates the cowhide into the detection bucket 7 to form bubbles, and then the detector 10 is started to record and observe the rate of bubble generation to detect the air permeability of the cowhide.
