[0054] Reference figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Picture 9 , Picture 10 , Picture 11 with Picture 12. A method for using pull-tab conveying equipment in a zipper assembly machine includes the following steps:
[0055] 1) The rotating disc 1 is rotated into position so that the upper vacant pull tab positioning device 2 is facing the pull tab conveying device 4;
[0056] 2) The pull-tab conveying device 4 is activated, and the pull-tabs 3 in the pull-tab vibrating hopper 41 are sequentially dropped into the diagonal-stay track 42 for transmission until they are delivered to the lower output end 422 of the diagonal-stay track 42 and are located at the lower output The side of the pull tab 3 of the end 422 conflicts with the push knife assembly 45;
[0057] 3) The first driving mechanism 46 acts to drive the push knife assembly 45 to move, thereby pushing the pull tab 3 that is in conflict with it to move. The pull tab 3 enters the feeding side 432 of the guide channel in the pull tab guide assembly 43 and slides into it. The elastic movable piece 44 in the pull-tab guide assembly 43 is pressed into the pull-tab guide assembly 43, and then the pull-tab 3 is pushed to the discharge side 433 of the guide channel, and then enters the opposite pull-tab positioning device 2 Then, the push-knife assembly 45 returns to its original position, and it conflicts with the next pull-tab side that falls into the output end 422 under the diagonal pull-tab track; after the pull-tab 3 leaves the elastic movable piece 44, the elastic movable piece 44 Can pop out and hold the next pull tab;
[0058] 4) After the pull tab 3 enters the pull tab positioning device 2, one side 34 of the pull tab 3 conflicts with the pull tab side limit block 24 in the pull tab positioning device 2, and the bottom surface 33 is in contact with the clip in the pull tab positioning device 2. The front and rear adjustment blocks 22 of the pull-tab collide, and the top surface 36 collides with the upper clamping plate 25 of the pull-tab positioning device;
[0059] 5) The rotating disc 1 continues to rotate until the pull-tab positioning device 2 is facing the pull-tab pushing device 5;
[0060] 6) The pull-tab pushing device 5 is activated, and the second driving mechanism 51 acts to drive the fish-eye bearing 52 to move, thereby pushing the pull-tab fixed slider 53 connected to the fish-eye bearing 52 to move, so that the slider 53 is fixed with the pull-tab The connected pull-tab fixing steel sheet 54 enters into the pull-tab positioning device 2 and interferes with the other side 32 of the pull-tab 3, and at the same time makes the pull-tab fixing small block 55 connected with the pull-tab fixing slider 53 and the pull-tab 3 The front end 31 conflicts, and then the pull tab 3 is pushed to make the rear end 35 of the pull tab conflict with the side limit block 24 of the pull tab, and the positioning of the pull tab is completed.
[0061] The foregoing are only specific implementations of the present invention, but the design concept of the present invention is not limited to this. Any insubstantial modification of the present invention using this concept should be an act that violates the protection scope of the present invention.
