Description

Zipper head penetrating device with zipper closing mechanism

Technical Field

The utility model relates to the technical field of zipper production, in particular to a zipper head penetrating device with a zipper closing mechanism.

Background

The zipper puller penetrating machine is a zipper production machine which is used for penetrating and installing a zipper puller on a zipper belt, so that the zipper belt can be opened and closed along with the movement of the zipper puller, and the main working parts of the zipper puller penetrating machine are a zipper belt vacancy sensor, a zipper puller penetrating die mechanism (comprising a fixed upper die and a movable lower die), a bifurcation rod and the like. When the zipper strip vacancy sensor detects the zipper strip vacancy, the bifurcation rod is controlled to move downwards to prop open the vacancy, the lower die moves upwards simultaneously, the pull head is sent to the preset position in the upper die, the upper die and the lower die are matched to enable the pull head to be located at the vacancy of the zipper strip, in this way, when the motor pulls the zipper strip to move, the pull head can be arranged on the zipper in a penetrating mode, then the bifurcation rod rises, when the pulling time of the zipper strip meets the preset time, the lower die moves downwards, and the pull head is pulled out of the die mechanism along with the zipper strip, so that the penetrating and installing of the pull head are completed.

However, after the zipper puller is worn, the part of the zipper where the zipper puller passes cannot be in an open state, when the zipper enters the next process or is easy to fall off in the transferring process, and the open part is required to be closed when the zipper is sewn and assembled, so how to enable the zipper to be closed after the zipper is worn is a very important problem to be solved.

The patent of the invention of the grant bulletin number CN102396852B discloses an automatic slider penetrating machine for a double-closed-end zipper, which comprises a rack; a zipper tape conveying device mounted on the frame; the knife supporting device is movably arranged on the frame and driven by the first power device and is used for supporting the knife edge part of the zipper belt; the pull head conveying device is arranged on the frame and used for conveying pull heads into a lower die cavity of the lower die body one by one; the pull head clamping device is arranged on the frame and used for clamping the pull head in the opening of the cutter opening of the zipper belt, the pull head clamping device comprises an upper die body fixedly arranged on the frame and provided with an upper die cavity, and a lower die device movably arranged on the frame, the lower die device comprises a lower die body movably arranged on the frame and provided with a lower die cavity, the lower die body is driven by a second power device, and a clamping die cavity used for clamping the pull head is formed when the upper die body and the lower die body are clamped; the automatic zipper threading machine with double closed ends further comprises a zipper closing device which is arranged on the frame and used for enabling the zipper strips separated after threading to close the closed ends, wherein the zipper closing device comprises a zipper closing anvil die which is fixedly arranged on the frame, a zipper closing lower die which is movably arranged on the frame and driven by a third power device, the zipper closing lower die comprises a strip body, a zipper closing groove which extends along the width direction of the strip body is arranged on the strip body, and fixing parts which extend towards two ends of the strip body are respectively arranged on two opposite sides of the zipper closing groove; the chain closing groove comprises a chain tooth guiding part and a chain tooth meshing part, and a transition circular arc is arranged between the chain tooth guiding part and the chain tooth meshing part; the open end of the tooth lead-in part is provided with an arc chamfer.

The patent realizes the automatic threading and closing of the zipper on one machine, thereby continuously and automatically producing the double-closed zipper, reducing the production cost and improving the production efficiency. However, the size of the zipper closing groove is fixed, and when the zipper with different widths is closed, the lower zipper closing die is required to be replaced, so that the quick production is not facilitated.
