[0029] The working process of the present application is as follows:

[0030] When the diaphragm of the diaphragm compressor needs to be detected, first, the diaphragm to be detected is placed in the storage frame 9, so that the diaphragm at the frontmost side of the storage frame 9 falls into the groove of the crimping block 72, the driving motor 62 is started to drive the screw rod 61 to rotate, so that the screw rod 61 drives the transverse sliding plates 5 on both sides of the sliding rail 4 to slide towards each other, the transverse sliding plates 5 drive the crimping block 72 to move through the frame body 71 to press the diaphragm, and in the process of moving of the crimping block 72, the gear one 73 is engaged with the rack one 75, and the crimping block 72 rotates in the process of moving, so as to realize the automatic crimping of the diaphragm by simulating the manual crimping action.

[0031] When the diaphragm is crimped to a certain degree, the driving motor 62 is reversely rotated to drive the crimping blocks 72 on both sides of the sliding rail 4 to move away from each other, so that the diaphragm gradually recovers flatness, the crimping block 72 continues to move to make the diaphragm fall out through the through slot arranged at the bottom of the rack 1, and the automatic discharging of the diaphragm is realized; in the process of continuous movement of the crimping block 72, the frame body 71 pushes the sliding frame 84, so that the sliding frame 84 drives the driving strip 83 to rotate, the driving strip 83 drives the stop plate 82 to slide towards the opening at the top of the rack 1, so that the stop plate 82 shields the positions on both sides of the opening at the top of the rack 1, avoiding the diaphragm in the storage frame 9 from falling; the stop plate 82 continues to slide to push the driving frame 106 through the inclined surface arranged on the driving block 109, so that the driving frame 106 drives the rack two 103 to slide, and the rack two 103 pulls the push plate 101 through the gear two 102, and in this process, the gear two 102 does not rotate under the action of the one-way bearing, so that the push plate 101 slides in the storage frame 9 to push the diaphragm.

[0032] After the push plate 101 finishes pushing, the driving motor 62 is reversely rotated to make the two crimping blocks 72 move towards each other, the sliding frame 84 is reset to slide under the action of the spring one 86, so that the stop plate 82 moves away from the opening at the top of the rack 1, the diaphragm in the storage frame 9 falls into the crimping block 72, and the automatic feeding of the diaphragm is realized; the driving block 109 is separated from the driving frame 106, the rack two 103 is reset to slide under the action of the spring two 105, at this time, the gear two 102 rotates, so that the push plate 101 does not move, and the above process can be repeatedly operated to realize the automatic detection of the diaphragm.
