Description

Technical Field

[0001] The utility model belongs to the field of zipper machine equipment and relates to a pulling safety device for a reverse hook ring. Background Art

[0002] The zipper threading and chaining machine is a fully automatic equipment that completes the chaining process after putting the slider on the chain belt. The slider is delivered to the upper end of the upper slider mold through the vibration plate and the slider feeding device, and then the upper slider mold delivers the slider to the threading and chaining machine at a fixed point. The upper slider mold is equipped with a pull safety device, which is a pull hook that hooks the pull ring on the slider when threading the chain to open the safety of the slider. The pull hook mainly plays two roles. The first point: when conveying the slider, hooking the pull ring can prevent the slider from jumping and causing displacement or flipping during the conveying process; the second point: pull the safety open so that the zipper can enter the slider. Since the slider feeding device is set in front of the upper slider mold, the pull hook cylinder of the pull hook is set on the side of the upper slider mold facing away from the feeding direction to prevent interference with the slider feeding device, so as to make the space utilization more reasonable. However, since the pull slot of the upper slider mold is open toward the feeding direction, the traditional pull hook is set on the side of the upper slider mold in the feeding direction, and moves from the side of the feeding direction to the side of the upper slider mold facing away from the feeding when hooking. Such a setting will inevitably affect the setting of the feeding device, and the setting of the feeding device is very limited. Summary of the invention

[0009] The utility model is further configured as follows: a cylinder fixing seat is fixed on one side of the middle part of the rear mold seat facing away from the feeding direction, and the cylinder fixing seat is fixedly connected to the hook cylinder.

[0010] The utility model is further configured as follows: the hook cylinder is fixed at the lower end of the cylinder fixing seat.

[0011] The utility model is further configured as follows: the cylinder fixing seat is provided with a limiting groove toward the hook groove, the limiting groove is communicated with the hook groove and matches with the hook.

[0012] By setting the limit groove, the pull hook can be limited, making the equipment run more stably.

[0013] The utility model is further configured as follows: a cylinder insertion groove and an adjustment groove are formed in the middle of the hook, the adjustment groove and the cylinder insertion groove are perpendicular to each other, a hinge hole is formed at the protruding end of the hook cylinder and is inserted into the cylinder insertion groove, a pin is arranged to pass through the adjustment groove and the hinge hole and is fixed with a nut to realize hinge connection.

[0014] By setting the adjusting slot, the positional relationship between the pull hook and the cylinder can be adjusted, thereby adjusting the running track of the pull hook.

[0015] The utility model is further configured as follows: the pull hook includes a hook body and a hook ring portion, the upper end of the hook body is formed with a mounting groove, the lower end of the hook ring portion is adapted to the mounting groove and formed with a slide groove, and the hook ring portion is fixed to the mounting groove by screws passing through the slide groove.

[0016] By setting the mounting groove and the sliding groove, the length of the hook portion can be adjusted to adapt to different pull rings.

[0017] The utility model is further configured as follows: the hook ring portion and the hook body form a clearance groove.

[0018] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: the pull hook and the pull hook cylinder are both arranged on the side of the upper slider mold facing away from the feed, so as not to affect the layout of the feeding device, and then through the arrangement of the lever cross block, the force of the pull hook on the slider is still in the direction away from the feeding device, so that the slider can be stably set on the upper slider mold and will not slip out from the opening of the slider groove.
