Double-puller penetrating machine

Abstract

The invention discloses a double-puller penetrating machine which comprises a machine frame, and the machine frame is provided with a positioning die, a pulling die, a pressing die, a pressing die and a pressing die, and the bottom face of the positioning die is provided with a positioning through groove; the first chain separating device is positioned on one side of the positioning mold; the second zipper separating device is positioned on the other side of the positioning mold; the first feeding device is provided with a first feeding die capable of moving up and down; the transferring device is provided with a transferring seat capable of moving in the direction close to or away from the first feeding die; the second feeding device is arranged on the transferring base and provided with a second feeding die capable of moving up and down, and when the transferring base drives the second feeding device to be close to the first feeding die and enables the second feeding die to be located under the positioning die, the arrangement direction from the first feeding die to the second feeding die is the same as the length extension direction of the positioning through groove; two zipper pullers can be transferred to the chain at the same time to be assembled, the two zipper pullers can be assembled to the chain through one-time assembling action, and the zipper assembling efficiency is greatly improved.

Description

technical field [0001] The invention relates to a zipper production equipment, in particular to a double slider threading machine. Background technique [0002] The head threading machine has a mechanism for pulling and feeding the chain. After feeding the zipper head to the feeding die, the zipper head is moved to the chain positioning through the feeding die. At the front side or the back side of the zipper head and the chain assembly, there is usually a chain separating device, which is used to separate the chain. Some zippers need to penetrate two zipper heads during production and assembly, which are usually set in the existing production equipment. With two threading machines, the chain needs to be passed through the two threading machines in turn, and the two threading machines are used to install the zipper heads on the chain one by one. The entire zipper assembly process has many operation steps, and it is difficult to improve the efficiency of zipper assembly. SU...

Problems solved by technology

[0002] The head threading machine has a mechanism for pulling the chain. After feeding the zipper head to the feeding mold, the zipper head is moved to the chain position through the feeding die. By pulling the zipper, the zipper head is inserted into the chain. At the front or rear side where the zipper puller and the chain are assembled, there is usually a chain splitting device for separating the chain. Some zippers need to be inserted into two zipper pullers during production and assembly. The existing production equipment is usually set Two threading machines need to pass the chain through the two threading machines in turn, and the two threading machines install the zipper heads on the chain one by one. The whole zipper assembly process has many steps, and it is difficult to improve the efficiency of zipper assembly.
