Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The invention will be further described in the following with reference to specific embodiments thereof,

as shown in fig. 1-2, a slider positioning compensation mechanism includes a branch chain platform 1, a moving module 2, and a pressing device 3 capable of pressing the moving module 2 downward, a first chain belt inlet 11 for a chain belt to enter is formed at the front end of the branch chain platform 1, a chain belt guiding track 12 is installed at the lower end of the first chain belt inlet 11, a slider mold base 4 capable of moving up and down is further connected at the rear end of the branch chain platform 1, a slider installing template 41 is installed at the upper end of the slider mold base 4, a slider positioning groove 411 for placing a slider is formed at the upper end of the slider installing template 41, a reset groove 21 is formed at the front end of the moving module 2, a first minute hand 22 passing through the lower end of the reset groove 21 and extending from the lower end of the moving module 2 is arranged in the reset groove 21, a reset spring positioned in the reset groove 21 is arranged at the upper end of the first minute hand 22, the lower end of the moving module 2 is also formed with a second minute hand 23 located at the rear end of the slider mounting template 41. Specifically, the chain belt is placed on the chain belt introducing track 12, enters the chain separating platform 1 through the first chain belt inlet 11, finally passes through the second chain belt inlet 131, and passes through the upper side of the slider mold seat 4. A slider having a size corresponding to the slider positioning groove 411 is put in the upper end of the slider attaching template 41. When the device works, the pressing device 3 presses the moving module 2 downwards, that is, the first minute hand 22 and the second minute hand 23 move downwards, and after the lower end of the second minute hand 23 contacts with the teeth on the chain belt penetrating out from the second chain belt inlet 131, the second minute hand 23 continues to press downwards to separate the mutually engaged teeth on the chain belt. When the mechanism detects a gap on the chain belt, the device controls the slider die holder 4 to move upwards, the slider in the slider positioning groove 411 is contacted with the chain belt, the slider die holder 4 continues to move upwards at the moment, through pressure, the chain teeth on the chain belt are pressed into the introducing port of the slider, and meanwhile, the first minute hand 22 is abutted against the slider to fix the slider, so that the slider is prevented from deviating in the process of being installed in the chain belt. And when the first minute hand 22 abuts against the slider, the first minute hand 22 does not move downwards any more, and the moving module 2 continues to drive the second minute hand 23 to move downwards and compress the return spring positioned at the upper end of the first minute hand 22 in the return groove 21. When the first minute hand 22 finishes the action of pulling up the slider, the pressing device 3 rises to the original position, at this time, the return spring is no longer pressed and begins to rebound, and upward force is applied to the moving module 2, so that the moving module 2 is reset. The pressing device 7 can be a cylinder or a motor and can realize corresponding movement.

As shown in fig. 1, a fastener tape clamping plate 13 located at the front end of the slider mold 4 is fixed to the chain separating platform 1, and a second fastener tape inlet 131 is formed through the fastener tape clamping plate. The strand passes through the second strand inlet 131 while being transported on the strand separating platform 1, and the position of the strand in the mechanism is further fixed by the clamping plate 13.

As shown in fig. 1, an element groove 121 for placing a fastener element is formed in the middle of the fastener tape introduction track 12. Specifically, the fastener tape placed on the fastener tape introduction track 12 can be more effectively fixed by placing the fastener elements engaged with the fastener tape on the fastener tape introduction track 12 in the fastener tape grooves 121.

As shown in fig. 2, the slider mounting template 41 is detachable and replaceable with respect to the slider mold 4. Specifically, the sizes of the sliders with different sizes in the slider positioning groove 411 are different, so that the slider mold base 4 needs to be replaced to achieve the purpose of installing the sliders with different sizes in the fastener tape.

As shown in fig. 2, a slider fixing panel 42 having a slit in the middle is installed at the lower end of the slider positioning groove 411. Specifically, the slider fixing panel 42 clamps the cap of the slider through the middle gap, so that the slider can be more effectively fixed, and the slider is prevented from being displaced in the process of rising and loading the slider mold 4 into the zipper tape.

As shown in fig. 2, the slider positioning groove 411 is not closed, and one end of the non-closed end faces the first sub-needle 22, and the inclined surface of the first sub-needle 22 faces the slider positioning groove 411. Specifically, the design is convenient for the inclined surface of the first minute hand 22 to smoothly abut against the slider when the first minute hand 22 moves downwards.

As shown in fig. 2, a convex body 221 for a return spring to be sleeved is formed at the upper end of the first minute hand 22. Specifically, the convex body 221 can fix the return spring mounted in the return groove 21, and prevent the return spring from being separated from the return groove 21 when the return spring is compressed.

Further, the width of the second minute hand 23 is larger than that of the first minute hand 22. Since the slider is small in volume, the width of the first minute hand 23 for abutting against the slider is not appropriate to be too large. The second minute hand 23 for dividing the chain is wider than the first minute hand 22 as shown, because the entrance that is opened when the chain belt is divided needs to be adapted to the whole slider to be put in.

The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
