TECHNICAL FIELD
[0001] The utility model relates to zip fastener manufacturing technical field, especially a puller placing seat of double puller. BACKGROUND
[0002] The traditional double puller zip fastener includes a chain belt and two pullers installed on the chain belt for opening and closing the chain belt, one end of the chain belt has a latch, the other end has a stopper, the puller has a zipper head body, a cap and a puller, the zipper head body is provided with a chain passing channel for the chain belt to pass through, both ends of the chain passing channel are respectively a zipper opening end and a zipper closing end, the end with a larger opening of the chain passing channel is the opening end, the end with a smaller opening is the closing end, the puller is connected with the cap, the end of the puller away from the cap has a pull opening. This kind of double puller zip fastener needs workers to separate two belt bodies of a group of zip fasteners from a whole chain belt during processing and production, then install two pullers on one belt body from the gap of the cloth end of the belt body, after installation, the workers pull the two pullers to the latch of the belt body, the latch of the other belt body is inserted into the two pullers, finally the workers pull the two pullers to the direction of the stopper for a certain distance, then install the next group of pullers; however, this manual puller installation method is low in efficiency.
[0003] To this end, the market appears to install two pull heads in the chain belt, such as the double pull head machine, the application number is 2019224572443, which includes a rack; The zipper tape conveying device mounted on the rack; The spacer device for opening the zipper tape is movably mounted on the rack; The upper die and the lower die for forming the chain guide channel when the mold is closed are mounted on the rack, the lower die includes a first lower die movably mounted on the rack and a second lower die; The first chain guide slot and the first zipper head clamping slot communicated with the first chain guide slot are sequentially arranged along the direction of the zipper tape conveying; The first chain guide slot is trumpet-shaped, the width of which decreases along the direction of the zipper tape conveying, the first chain guide slot includes a chain tooth inlet and a chain tooth outlet; When the first zipper head clamping slot is placed with the zipper head, the chain tooth outlet corresponds to the chain inlet of the zipper head; The second zipper head clamping slot and the second chain guide slot communicated with the second zipper head clamping slot are sequentially arranged along the direction of the zipper tape conveying; The first zipper head clamping slot and the second zipper head clamping slot are symmetrically arranged; The first zipper head conveying device mounted on the rack is used to send the zipper head into the first zipper head clamping slot; The second zipper head conveying device mounted on the rack is used to send the zipper head into the second zipper head clamping slot. When applied, the first zipper head conveying device conveys the first zipper head into the first zipper head clamping slot, while the second zipper head conveying device conveys the second zipper head into the second zipper head clamping slot, after the zipper head is conveyed, the first zipper head conveying device and the second zipper head conveying device return to the original position. The chain joint part (the end of the engaged zipper) of the first zipper head and the second zipper head is symmetrically arranged. At this time, the chain tooth outlet of the first chain guide slot is aligned with the chain inlet of the first zipper head. Then, the first lower die and the second lower die are driven by the cylinder to approach each other, and the upper die is closed. The spacer device opens the zipper tape, and the zipper tape changes from the engaged state to the separated state. The zipper tape conveying device drives the zipper tape to move forward, the zipper teeth of the separated zipper tape enter the first chain guide slot through the chain tooth inlet of the first chain guide slot, then enter the chain inlet of the first zipper head through the chain tooth outlet of the first chain guide slot, and then complete the first zipper head threading through the chain joint part of the first zipper head. The zipper tape again completes engagement. Because the chain joint part (the end of the engaged zipper) of the first zipper head and the second zipper head is symmetrically arranged, the zipper tape immediately enters the chain joint part of the second zipper head after engagement; Then through the chain inlet of the second zipper head and the second chain guide slot, the zipper tape again becomes a separated state, completing the threading of two zipper heads at a time. When threading the zipper head is completed, the two zipper heads are symmetrically distributed with the tail parts opposite on the zipper tape, and the zipper tape between the two zipper heads is in an engaged state.
[0004] However, the zipper head is embedded in the first zipper clamping groove and the second zipper clamping groove when the zipper head is inserted into the zipper tape, and if zipper heads of different sizes need to be inserted, the entire lower mold body needs to be replaced, and the first pull piece fixing device and the second pull piece fixing device are also installed on the lower mold body, which is relatively troublesome to disassemble, so that the overall device cannot adapt to zipper heads of different sizes for insertion.
[0005] Therefore, the inventor of the present application has conducted in-depth research on the problem, and thus the present application is produced. Content of the Utility Model
