Detailed Description

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

as shown in fig. 1 and 2, a zipper slider safety opening mechanism of a slider attaching machine comprises a die holder 1 for fixing a zipper slider 6, wherein an air cylinder 2 is arranged on one side of the die holder 1, a pin 4 acting on a pull tab 7 on the zipper slider 6 is arranged on a piston rod 3 of the air cylinder 2, the pin 4 comprises a connecting end 41 connected with one side of the piston rod 3, and a free end 42 extending from the connecting end 41 and acting on an opening 71 of the pull tab 7 of the zipper slider 6, and the free end 42 is in a triangular shape. The free end 42 of the contact pin 4 is triangular, when the contact pin 4 moves forward under the pushing of the piston rod 3, the foremost end of the free end 42 is thin, so that the contact pin can conveniently extend into the opening 71 of the pull tab 7, along with the continuous movement of the free end 42 to the side close to the zipper puller 6, the free end 42 completely enters the opening 71 of the pull tab 7, the opening 71 of the pull tab 7 interferes with the free end 42 of the contact pin 4, at the moment, the contact pin 4 can still continue to advance under the pushing of the piston rod 3, but at the moment, the pull tab 7 can be driven to move together to pull the pull tab 7 forward, and as the zipper puller 6 is fixed on the die holder 1, the pull tab 7 can open the safety in the zipper puller 6. When the free end 42 of the contact pin 4 approaches the opening 71 of the pull tab 7, the thinner end firstly extends into the opening 71, and then interference is formed between the thicker end and the opening 71 of the pull tab 7, so that the pull tab 7 is driven to open the safety, therefore, the contact pin can be adapted to the upper sliders of zipper pullers of various specifications to work, and the free end 42 in a triangular shape firstly extends into the opening 71 and then interference is formed no matter the size of the opening 71 on the pull tab 7, so that the pull tab 7 is driven.

Further, the free end 42 includes an upper acting edge 421 and a lower acting edge 422, the upper acting edge 421 is substantially parallel to the upper and lower end surfaces of the die holder 1, and the lower acting edge 422 is inclined to the upper and lower end surfaces of the die holder 1. Since the zipper head 6 is fixed on the die holder 1, in order to prevent the free end 42 of the pin 4 from propping against the die holder 1 when moving forward, the upper acting edge 421 is set to be in a state of keeping parallel with the upper and lower end surfaces of the die holder 1, the free end 42 of the pin 4 will not prop against the die holder 1, and only acts on the pull tab 7, therefore, in order to keep the free end 42 in a triangular shape, the lower acting edge 422 of the pin 4 needs to form an included angle with the upper and lower end surfaces of the die holder 1.

Furthermore, the included angle formed by the upper acting edge 421 and the lower acting edge 422 is 20-40 degrees. The thinner the front end of the free end 42 of the pin 4, the longer the portion of the pin 4 that can pass through the opening 71 of the tab 7, and the harder it is for the free end 42 of the pin 4 to come out of the opening 71 of the tab 7, but the thinner the front end of the free end 42, the longer the period of interference between the two will occur, and the time for opening the safety will be affected, so the angle between the upper acting edge 421 and the lower acting edge 422 of the free end 42 is preferably in the range of 20-40 °.

Further, the front end of the free end 42 is rounded. The free end 42 is rounded at the front end, so that the free end 42 can more easily enter the opening 71 of the tab 7.

Further, a connecting seat 5 is further arranged between the contact pin 4 and the piston rod 3, a threaded hole 51 is formed in the connecting seat 5, an adjusting groove 43 is formed in the connecting end 41 of the contact pin 4, and the adjusting groove 43 is connected with the threaded hole 51 through a fastening piece. In order to better fit the free end 42 of the pin 4 with the opening 71 of the pull tab 7, the position of the pin 4 can be adjusted through the threaded hole 51 on the connecting seat 5 and the adjusting groove 43 on the connecting end 41 of the pin 4, so that the free end 42 of the pin 4 can be better aligned with the opening 71 of the pull tab 7. The fasteners are not shown in the figures, but are readily understood by those skilled in the art.

Further, a limiting region 52 which is recessed inwards is arranged on the connecting seat 5, and the connecting end 41 is located in the limiting region 52 and can slide up and down. The defined area 52 enables the connecting end 41 of the pin 4 to be adjusted in the adjustment position only in the up-down direction without rotating, resulting in a change of the angle of the free end 42 of the pin 4.

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.
