Technical Field

The utility model relates to the technical field of zipper production equipment, in particular to an automatic zipper penetrating and closing machine with a resin injection molding opening zipper front code as a bevel edge.

Background

The prior zipper is provided with a zipper head and a zipper belt, wherein the zipper belt is provided with a first zipper belt and a second zipper belt, the first end part of the first zipper belt is provided with a square block, the first end part of the second zipper belt is provided with a bolt inserted into the square block, the second end part of the first zipper belt and the second end part of the second zipper belt are provided with a front code, and the front code is a square block; the pull head is provided with an upper wing plate, a lower wing plate and a connecting column arranged between the upper wing plate and the lower wing plate, the top surface of the upper wing plate is provided with a trunk, the trunk is provided with a pull tab, and a chain belt penetrating channel through which a first chain belt and a second chain belt respectively penetrate correspondingly is formed between the upper wing plate and the lower wing plate. During production, the pull head and the chain belt are produced separately, and the pull head and the chain belt are required to be pulled together after production so as to be sold. The traditional zipper is pulled and closed in a way that the manual zipper puller is arranged on the zipper belt, so that the working efficiency is low, and later mechanical operation is adopted, namely, the zipper puller is arranged on the zipper belt through a zipper closing machine. However, such a fastener closing machine operates by unwinding a fastener tape for a certain length, then loading a slider into a first fastener tape from a front end of the first fastener tape in a straight manner, inserting a pin into a square of the first fastener tape to close the first fastener tape and a second fastener tape, and since the slider is inserted into the front end of the first fastener tape in a straight manner, when the slider pulls one fastener tape, it is possible to load the next slider into the first fastener tape only by cutting the fastener tape, and thus the slide fastener is one tape when sold, and is not easy to transport. Therefore, the first zipper tape with the front code having the inclined opening is also shown on the market, namely, the front code on the first zipper tape is provided with the through openings penetrating through the two sides of the front code in the width direction in a concave manner, the through openings are obliquely arranged, the front code is provided with the inclined opening which is inclined from inside to outside in the square direction, thus, after the whole roll of zipper tape is formed, a plurality of closed sections are arranged, the zipper tape is arranged between the two closed sections, namely, the first zipper tape structure and the second zipper tape structure which are separately arranged are arranged, in this way, the front code inclined opening of the first zipper tape in the zipper tape corresponds to the zipper tape, the zipper tape penetrates through the channel and is obliquely inserted into the front code, so that the zipper tape can be assembled into the first zipper tape to the square, finally, the bolt of the second zipper tape is inserted into the square, the first zipper tape and the second zipper tape are assembled into the first zipper tape, then, the next zipper tape is directly inclined from the space between the first zipper tape and the second zipper tape, thus repeatedly arranged, a plurality of rolling and finally, the whole roll of zipper tape is formed, and after the whole roll of zipper tape is sold, the whole zipper tape is manufactured, and the whole zipper tape can be directly closed at the position after the whole roll of the zipper tape is produced. The chain belt strip realizes the effect of whole roll sales after each slider is assembled, but the existing zipper closing machine is only suitable for the mode that the sliders are inserted and installed on the front zipper in a straight mode, and cannot be suitable for the installation of the sliders on the front zipper with the bevel ports, so that the installation of the sliders on the front zipper with the bevel ports can only be manually operated, and the problem of low production efficiency is caused.

In view of the above, the present inventors have conducted intensive studies on the above problems, and have resulted from the present utility model.
